We need to parse the puzzle. The description: "You are solving a grid transformation puzzle. You are given a metaphorical description of the transformation, training examples, and a test input grid."

We have a color key mapping letters to colors. The puzzle: "What you see: A small 3×3 tapestry hangs in a dark hall. One thread—a single row or column—is woven from a single pure color, forming the flagpole that holds the whole design together. The rest of the weave is a patchwork of different colors. What to do: The flagpole knows which wall it belongs to. A row-pole is horizontal and knows its height; a column-pole is vertical and knows its side. The tapestry longs to be seen, so it unfurls itself three times along the direction of its pole, like a banner repeating in the wind. Wherever the banner doesn't reach, the dark hall remains—empty black stone stretching into shadow. Grid details: The dark hall is a 9×9 chamber of black stone. The flagpole's position decides which strip of the chamber gets decorated: a horizontal pole at the top, middle, or bottom places three copies side by side in the matching horizontal band; a vertical pole on the left, center, or right stacks three copies in the matching vertical band. The rest of the chamber stays dark and bare."

So we have a 3x3 input grid. We need to produce a 9x9 output grid. The input grid has a "flagpole" which is a single row or column that is a single pure color. That row or column is the "pole" that determines orientation and location. The rest of the grid is patchwork of colors. The transformation: replicate the 3x3 tapestry three times along the direction of its pole, like a banner repeating in the wind. The 9x9 output grid is a 3x3 block repeated 3 times along the direction of the pole. The rest of the 9x9 grid remains black (represented by '.' maybe). The 9x9 grid is a "dark hall" of black stone. The flagpole's position decides which strip of the chamber gets decorated: a horizontal pole at the top, middle, or bottom places three copies side by side in the matching horizontal band; a vertical pole on the left, center, or right stacks three copies in the matching vertical band. The rest of the chamber stays dark and bare.

So we need to identify the flagpole: a single row or column that is a single pure color. In the input grid, we need to find a row or column that is all the same color. That row or column is the flagpole. The orientation of the flagpole (horizontal or vertical) determines the direction of replication. The position of the flagpole (top, middle, bottom for horizontal; left, center, right for vertical) determines which band of the 9x9 output grid will be filled with the repeated pattern. The repeated pattern is the entire 3x3 tapestry repeated 3 times along the direction of the pole. So if the pole is horizontal, we replicate the 3x3 block horizontally 3 times, resulting in a 3x9 block. That block will be placed in the corresponding horizontal band of the 9x9 grid: top band (rows 0-2), middle band (rows 3-5), bottom band (rows 6-8). If the pole is vertical, we replicate the 3x3 block vertically 3 times, resulting in a 9x3 block. That block will be placed in the corresponding vertical band of the 9x9 grid: left band (cols 0-2), center band (cols 3-5), right band (cols 6-8). The rest of the 9x9 grid remains black ('.').

We need to confirm with the training example.

Example 1:
Input:
B B B
M R R
R R M

Output:
B B B B B B B B B
M R R M R R M R R
R R M R R M R R M

Let's analyze. Input grid 3x3:

Row0: B B B
Row1: M R R
Row2: R R M

We need to find a row or column that is a single pure color. Let's check rows: Row0 is B B B (all B). Row1 is M R R (not all same). Row2 is R R M (not all same). So the flagpole is row0, which is horizontal, top row. So orientation horizontal, position top. So we replicate the 3x3 block horizontally 3 times, resulting in a 3x9 block. That block is placed in the top band of the 9x9 grid. The output shows that: first 3 rows are the repeated pattern: row0 repeated 3 times: B B B B B B B B B. Row1 repeated 3 times: M R R M R R M R R. Row2 repeated 3 times: R R M R R M R R M. The rest of the 9x9 grid is black ('.'). Indeed, the output shows 9 rows: first 3 rows are the repeated pattern, next 6 rows are all '.'.

Thus the rule matches.

Now we need to apply to test input:

Test Input:
M M G
Y Y G
Y Y G

We need to find the flagpole: a row or column that is a single pure color. Let's examine rows:

Row0: M M G (not all same)
Row1: Y Y G (not all same)
Row2: Y Y G (not all same)

Columns:

Col0: M Y Y (not all same)
Col1: M Y Y (not all same)
Col2: G G G (all G). So column 2 is all G. So the flagpole is column 2, vertical, rightmost column. So orientation vertical, position right. So we replicate the 3x3 block vertically 3 times, resulting in a 9x3 block. That block will be placed i

We need to solve the puzzle. Let's parse the problem carefully.

We have a grid transformation puzzle. Input is a 3x3 grid. Output is a 9x9 grid. The description: "What you see: A 3×3 organism with one structural spine — a row or column of identical tissue running through it. What to do: The spine determines the axis of mitosis. The organism replicates itself three times along that axis, embedding into a larger 9×9 body of dormant (black) tissue at the position matching the spine's location. Grid details: Input: 3×3. Output: 9×9, mostly black. Three copies of the input arranged in a strip corresponding to the spine's position and orientation."

So we need to identify the "spine" in the 3x3 input: a row or column of identical tissue (i.e., same color). The spine determines the axis of mitosis. The organism replicates itself three times along that axis, embedding into a larger 9x9 body of dormant (black) tissue at the position matching the spine's location.

Thus, we need to find a row or column that has all identical colors. That row/column is the spine. Then we replicate the entire 3x3 input three times along that axis, i.e., we create a 9x9 grid where the 3x3 input is repeated three times along that axis, and the rest of the grid is black (.). The output examples confirm this.

Let's analyze the training examples.

Example 1:

Input:
B B B
M R R
R R M

We need to find a row or column of identical tissue. Let's check rows:

Row 1: B B B -> all B. So row 1 is a spine. Row 2: M R R -> not all same. Row 3: R R M -> not all same.

Columns:

Col 1: B M R -> not all same. Col 2: B R R -> not all same. Col 3: B R M -> not all same.

So the spine is row 1 (top row). The axis of mitosis is horizontal (row). The organism replicates itself three times along that axis, embedding into a larger 9x9 body of dormant (black) tissue at the position matching the spine's location.

So we replicate the 3x3 input three times horizontally? Wait, the axis is horizontal, so we replicate along that axis: we create a 9x9 grid where the 3x3 input is repeated three times along the horizontal axis (i.e., left to right). But the output shows:

Output:
B B B B B B B B B
M R R M R R M R R
R R M R R M R R M
. . . . . . . . .
. . . . . . . . .
. . . . . . . .
. . . . . . . .
. . . . . . . .
. . . . . . . .

Let's examine the output: The first row is B B B B B B B B B. That is 9 B's. The second row is M R R M R R M R R. That's 9 cells: M R R repeated 3 times. Third row: R R M repeated 3 times. Then the rest of the grid is black.

So indeed, the 3x3 input is repeated horizontally 3 times, forming a 3x9 block. Then the rest of the 9x9 grid is black. The 3x9 block is placed at the top of the 9x9 grid because the spine is the top row. So the 3x9 block occupies rows 1-3, columns 1-9. The rest rows 4-9 are black.

Thus, the rule: find the spine row or column. If it's a row, replicate the 3x3 input horizontally 3 times, forming a 3x9 block. Place that block at the row index of the spine (i.e., if spine is row 1, place at rows 1-3; if spine is row 2, place at rows 4-6; if spine is row 3, place at rows 7-9). The columns are always 1-9. The rest of the grid is black.

If the spine is a column, replicate the 3x3 input vertically 3 times, forming a 9x3 block. Place that block at the column index of the spine (i.e., if spine is column 1, place at columns 1-3; if spine is column 2, place at columns 4-6; if spine is column 3, place at columns 7-9). The rows are always 1-9. The rest of the grid is black.

Let's confirm with Example 2.

Example 2 Input:
R Y G
R G Y
R G Y

Check rows: Row 1: R Y G -> not all same. Row 2: R G Y -> not all same. Row 3: R G Y -> not all same.

Columns: Col 1: R R R -> all R. So column 1 is the spine. So we replicate the 3x3 input vertically 3 times, forming a 9x3 block. Place that block at column 1 (i.e., columns 1-3). The output shows:

Output:
R Y G . . . . . .
R G Y . . . . . .
R G Y . . . . . .
R Y G . . . . . .
R G Y . . . . . .
R G Y . . . . . .
R Y G . . . . . .
R G Y . . . . . .
R G Y . . . . . .

Let's check: The first 3 rows: R Y G, R G Y, R G Y. Then row 4: R Y G, row 5: R G Y, row 6: R G Y, row 7: R Y G, row 8: R G Y, row 9: R G Y. So indeed, the 3x3 input is repeated vertically 3 times, forming a 9x3 block. The rest of the grid (columns 4-9) is black. So the rule holds.

Example 3 Input:
G B M
G M B
G B M

Check rows: Row 1: G B M -> not all same. Row 2: G M B -> not all same. Row 3: G B M -> not all same.

Columns: Col 1: G G G -> all G. So column 1 is the spine. So replicate vertically 3 times, forming a 9x3 block at columns 1-3. Output:

G B M . . . . . .
G M B . . . . . .
G B M . . . . . .
G B M . . . . . .
G M B . . . . . .
G B M . . . . . .
G B M . . . . . .
G M B . . . . . .
G B M . . . . . .

Yes, matches.

Thus, the rule is confirmed.

Now we need to apply to the test input:

We need to parse the puzzle. The description: "What you see: A 3×3 pastry where one layer is a single pure ingredient — the baking sheet — and the rest is mixed filling. What to do: Place the pastry on a 9×9 oven rack (black background). The baking sheet's position on the rack determines which shelf gets loaded: tile the pastry three times along that shelf, leaving the other shelves empty."

Interpretation: Input is a 3x3 grid. There is a "single pure ingredient" layer: a uniform color? The rest is mixed filling: other colors. The "baking sheet" is the uniform layer. The "position" of that uniform layer in the 3x3 grid determines which shelf (row) in the 9x9 output gets loaded. Then we tile the pastry (the entire 3x3 input) three times along that shelf (i.e., horizontally? or vertically?). The output is a 9x9 grid with a strip of three tiled copies of the input placed at the position indicated by the uniform layer. The rest of the grid is black (represented by .). The output examples confirm this.

Let's analyze the training examples to confirm.

Example 1:

Input:
B B B
M R R
R R M

We need to find the uniform layer: a single pure ingredient. In the input, we see B B B in the first row: all B. So the uniform layer is B. The position of that uniform layer in the 3x3 grid: it's the first row (row index 0). So the shelf to load is row 0? But the output shows the first 3 rows of the 9x9 grid are filled with the tiled copies of the input. Let's examine output:

Output:
B B B B B B B B B
M R R M R R M R R
R R M R R M R R M
. . . . . . . . .
. . . . . . . . .
. . . . . . . . .
. . . . . . . . .
. . . . . . . . .
. . . . . . . . .

So the first 3 rows are filled with the tiled copies of the input. The rest are black. So the uniform layer was in row 0, so the shelf loaded is row 0. The 9x9 grid is 9 rows, each row has 9 columns. The "shelf" is a row of 9 cells. The "tile the pastry three times along that shelf" means we tile the 3x3 pastry horizontally 3 times to fill the 9 cells of that row. But the output shows that the first 3 rows are filled, not just the first row. Wait, the output shows the first 3 rows are filled with the tiled copies of the input. That means the "shelf" might be a vertical column of 3 rows? Let's analyze.

The output shows the first 3 rows are filled with the 3x3 pastry repeated horizontally 3 times. That means the 3x3 pastry is repeated horizontally 3 times to fill a 3x9 block. That block occupies rows 0-2 and columns 0-8. So the "shelf" is a 3-row tall block. The uniform layer's position determines which shelf gets loaded. The uniform layer is in row 0 of the 3x3 pastry. That corresponds to the top shelf (rows 0-2). So the shelf is a 3-row block. The "tile the pastry three times along that shelf" means tile horizontally 3 times across the 9 columns. So the output is 9x9 with a 3x9 block of the tiled pastry at the shelf determined by the uniform layer's row. The rest of the grid is black.

Let's confirm with Example 2.

Example 2 Input:
R Y G
R G Y
R G Y

Uniform layer: The first column is R R R. So uniform layer is R. Its position: column 0. So the shelf to load is column 0? But the output shows the first 3 columns are filled with the tiled pastry repeated vertically 3 times? Let's examine output:

Output:
R Y G . . . . . .
R G Y . . . . . .
R G Y . . . . . .
R Y G . . . . . .
R G Y . . . . . .
R G Y . . . . . .
R Y G . . . . . .
R G Y . . . . . .
R G Y . . . . . .

So the first 3 columns are filled with the 3x3 pastry repeated vertically 3 times. That is, the 3x3 pastry is repeated vertically 3 times to fill a 9x3 block. That block occupies rows 0-8 and columns 0-2. So the shelf is a 3-column wide block. The uniform layer's column index 0 corresponds to the leftmost shelf. So the shelf is a vertical column of 3 cells? Wait, the shelf is a 3x9 block? Let's analyze.

In Example 1, the uniform layer was in row 0, and the output had a 3x9 block at the top. In Example 2, the uniform layer was in column 0, and the output had a 9x3 block on the left. So the shelf is a 3x9 block if the uniform layer is in a row, and a 9x3 block if the uniform layer is in a column. But the description says "tile the pastry three times along that shelf". The shelf is a 3x9 or 9x3 block? Let's think.

The pastry is 3x3. The shelf is a 3x9 block if the uniform layer is in a row. The pastry is tiled horizontally 3 times to fill the 9 columns. The shelf is 3 rows tall. So the shelf is a 3x9 block. Similarly, if the uniform layer is in a column, the shelf is a 9x3 block. The pastry is tiled vertically 3 times to fill the 9 rows. So the shelf is 9 rows tall.

Thus the rule: Identify the uniform layer (a row or column of identical color). Determine its position: if it's a row, the shelf is the corresponding row of the 9x9 grid (i.e., rows 0-2, 3-5, or 6-8). If it's a column, the shelf is the corresponding column of the 9x9 grid (i.e., columns 0-2, 3-5, or 6-8). Then tile the 3x3 pastry horizontally

## Metaphorical Description

What you see: A 3×3 formation of players, one row or column wearing matching jerseys.
What to do: On a 9×9 field (empty/black), the uniformed line picks the lane. The whole formation is repeated three times along that lane at the matching position, and the rest of the field stays empty.
Grid details: Input: 3×3. Output: 9×9 empty field with three copies of the formation tiled in a strip matching the uniformed line's position and direction."

So we have a 3x3 input grid. We need to produce a 9x9 output grid. The output grid is empty except for three copies of the formation repeated along a lane (row or column) that matches the uniformed line's position and direction. The uniformed line is a row or column of matching jerseys. So we need to identify a row or column in the 3x3 input that has all same color. That row or column is the "uniformed line". Then we need to replicate the entire 3x3 formation three times along that lane in the 9x9 output. The lane is a row or column in the 9x9 grid. The lane's position and direction correspond to the uniformed line's position and direction. So if the uniformed line is a row (top, middle, bottom) in the 3x3 input, then we replicate the 3x3 formation three times along that row in the 9x9 output. Similarly for a column.

But we need to interpret "the uniformed line picks the lane. The whole formation is repeated three times along that lane at the matching position, and the rest of the field stays empty." So we need to place the 3x3 formation three times along the lane. The lane is a row or column in the 9x9 grid. The lane's position and direction match the uniformed line's position and direction. So if the uniformed line is the top row of the 3x3 input, then the lane is the top row of the 9x9 output. Then we need to tile the 3x3 formation three times along that lane. But how to tile? The 3x3 formation is 3x3. The lane is a row or column of length 9. We need to place the 3x3 formation three times along that lane. That means we need to place the 3x3 formation at positions that align with the lane. For a row lane, we would place the 3x3 formation at columns 0-2, 3-5, 6-8 of that row. But the 3x3 formation is 3x3, so we need to place it in a 3x3 block. For a row lane, we would place the 3x3 formation in the lane row and the two rows below or above? Wait, the lane is a row or column. The formation is 3x3. If the lane is a row, we need to place the formation such that its row aligns with the lane row. But the formation has 3 rows. So we need to decide which rows of the 9x9 output the formation occupies. The lane is a row, but the formation is 3 rows tall. So maybe the lane is a column? Let's examine the example.

Example 1:

Input:
B B B
M R R
R R M

Output:
B B B B B B B B B
M R R M R R M R R
R R M R R M R R M
. . . . . . . . .
. . . . . . . . .
. . . . . . . .
. . . . . . . .
. . . . . . . .
. . . . . . . .

So the output is 9x9. The first 3 rows are filled with the 3x3 formation repeated 3 times horizontally. The rest of the rows are empty (black). So the lane is the top row? Wait, the uniformed line in the input: Let's examine the input. Input grid:

Row 0: B B B
Row 1: M R R
Row 2: R R M

We need to find a row or column with matching jerseys. Row 0: B B B (all same). Row 1: M R R (not all same). Row 2: R R M (not all same). Column 0: B M R (not same). Column 1: B R R (not same). Column 2: B R M (not same). So the uniformed line is row 0 (top row). So the lane is the top row of the 9x9 output. But the output shows the 3x3 formation repeated horizontally across the first 3 rows, not just the top row. Wait, the output shows the first 3 rows filled with the 3x3 formation repeated horizontally. That means the lane is the top 3 rows? But the description says "the uniformed line picks the lane. The whole formation is repeated three times along that lane at the matching position, and the rest of the field stays empty." So maybe the lane is a 3-row strip (like a horizontal lane of 3 rows). The uniformed line is a row of matching jerseys. That row indicates the lane's vertical position: top, middle, bottom. So the lane is a 3-row strip that starts at that row. For example, if the uniformed line is the top row, then the lane is the top 3 rows. If the uniformed line is the middle row, then the lane is the middle 3 rows (rows 3-5). If the uniformed line is the bottom row, then the lane is the bottom 3 rows (rows 6-8). Similarly for columns: if the uniformed line is a column, then the lane is a 3-column strip.

Thus, the lane is a 3x9 or 9x3 strip. The formation is 3x3. The lane is 3 rows tall (if horizontal) or 3 columns wide (if vertical). The format

## Metaphorical Description

What you see: A 3×3 blueprint with one structural wall — a row or column built from one uniform material.
What to do: Expand to a 9×9 city block of empty lots (black). The load-bearing wall's orientation and position determine the avenue; tile the blueprint three times along that avenue.
Grid details: Input: 3×3. Output: 9×9 empty block with three copies of the input tiled in a strip matching the wall's position and axis."

So we have a 3x3 input grid. There is a "structural wall" which is a row or column built from one uniform material. That means there is a row or column that is all the same color. That row or column is the "wall". The orientation and position of that wall determine the avenue. Then we tile the blueprint three times along that avenue. The output is a 9x9 grid of empty lots (black) with three copies of the input tiled in a strip matching the wall's position and axis.

We need to analyze the training examples to confirm.

Example 1:

Input:
B B B
M R R
R R M

So the grid is:

Row1: B B B
Row2: M R R
Row3: R R M

We need to find a row or column that is uniform. Let's check rows: Row1 is B B B (uniform). Row2 is M R R (not uniform). Row3 is R R M (not uniform). Columns: Column1: B M R (not uniform). Column2: B R R (not uniform). Column3: B R M (not uniform). So the uniform row is Row1 (top row). So the wall is the top row. Orientation: horizontal. Position: top row. So the avenue is horizontal at the top? The output is 9x9 grid. Let's examine the output:

Output:
B B B B B B B B B
M R R M R R M R R
R R M R R M R R M

Wait, the output shows 9 rows, each with 9 columns. The first 3 rows are filled with the input repeated horizontally 3 times. The rest 6 rows are all '.' (black). So the output is a 9x9 grid where the first 3 rows contain 3 copies of the input side by side horizontally. The rest rows are empty.

But the description says "tile the blueprint three times along that avenue." The avenue is determined by the wall's orientation and position. In this case, the wall is the top row. So the avenue is horizontal at the top. So we tile the blueprint 3 times along that avenue. That means we replicate the blueprint horizontally 3 times, but only in the rows that correspond to the avenue? Wait, the output shows the blueprint repeated horizontally 3 times across the entire 9x9 grid, but only in the first 3 rows. The rest rows are empty. So the blueprint is repeated horizontally 3 times, but only in the rows that correspond to the wall's position? Actually the blueprint is repeated horizontally 3 times across the entire width, but only in the rows that correspond to the wall's position? Let's analyze.

The blueprint is 3x3. The output is 9x9. The blueprint is repeated horizontally 3 times, giving 3x3 repeated horizontally 3 times: 3 rows of 9 columns. That matches the first 3 rows of the output. The rest 6 rows are empty. So the blueprint is repeated horizontally 3 times, but only in the rows that correspond to the wall's position? Wait, the wall is the top row. So the blueprint is repeated horizontally 3 times in the rows that correspond to the wall's position? But the wall's position is the top row. So we might think that the blueprint is repeated horizontally 3 times in the rows that correspond to the wall's position? But the output shows the blueprint repeated horizontally 3 times in the first 3 rows, not just the top row. So maybe the rule is: The blueprint is repeated horizontally 3 times in the rows that correspond to the wall's position? But the wall's position is the top row, but the blueprint is repeated in all 3 rows. So maybe the rule is: The blueprint is repeated horizontally 3 times in the rows that correspond to the wall's orientation? Wait, the orientation is horizontal. So we tile along the horizontal axis. That means we replicate the blueprint horizontally 3 times. But we also replicate it vertically? Actually the output shows the blueprint repeated horizontally 3 times, but not vertically. So the blueprint is repeated horizontally 3 times, but only in the rows that correspond to the wall's orientation? But the orientation is horizontal, so we replicate horizontally. But we also replicate vertically? Let's analyze the second example.

Input:

So the grid:

Row1: R Y G
Row2: R G Y
Row3: R G Y

Check uniform rows: Row1: R Y G (not uniform). Row2: R G Y (not uniform). Row3: R G Y (not uniform). Uniform columns: Column1: R R R (uniform). Column2: Y G G (not uniform). Column3: G Y Y (not uniform). So the uniform col

We need to understand the puzzle. We have a metaphorical description: "Scattered across a vast dark field lie colored sticks of different lengths — each a single pure color, each lying perfectly straight, no two alike. They look abandoned, but each one remembers its size. What to do: The longest stick claims authority and bends itself into a square frame — the outermost shell of a nesting doll. The next longest stick, humbled, curls inside that frame to form a smaller shell within. Each remaining stick, from longest to shortest, takes its turn nestling inside the one before it, like matryoshka dolls stacking inward. The tiniest stick — perhaps just a splinter — finds itself cradled at the very heart. Grid details: The result is a perfect square portrait of nested shells, each exactly one layer thick, with the mightiest stick's color as the outer skin and the smallest stick's color glowing at the core. No darkness remains — every inch is claimed by a shell."

So we have a grid with colored cells. The input grid has colored cells scattered. The output grid is a square of nested shells, each one layer thick, with colors from outermost to innermost corresponding to the longest to shortest sticks. The longest stick is the longest line of same color? Or the longest contiguous line? The input grid has colored cells forming lines? Let's examine Example 1.

Example 1 Input: 22x? Actually the input grid is 22 columns? Let's count: The first line: ". . . . . . . . . . . . . . . . . . . . . ." That's 22 cells. So grid is 22x22? Actually there are 22 lines. So 22x22 grid. The input has some colored cells: B, G, M. Let's examine the pattern: The B cells form a vertical line at column 12? Let's check: In row 3: ". . . . . . . . . . . . . B . . . . . . . ." So B at column 13? Wait indexing: Let's count: columns 1-22. Row 3: after 12 dots, B at column 13? Actually row 3: ". . . . . . . . . . . . . B . . . . . . . ." So there are 12 dots, then B, then 9 dots? Let's count: 12 dots, B, 9 dots = 22. So B at column 13. Row 4: ". . . . G . . . . . . . . B . . . . . . . ." So G at column 5, B at column 13. Row 5: same. Row 6: same. Row 7: same. Row 8: ". . . . . . . . . . . . . B . . . . . . . ." So B at column 13. Row 9: ". . . . . . . . M . . . . . . . . . . . . ." So M at column 9? Wait row 9: after 8 dots, M at column 9, then 12 dots. Row 10: same. Row 11-22: all dots.

So the input has a vertical line of B at column 13 from rows 3-8. A vertical line of G at column 5 from rows 4-7. A vertical line of M at column 9 from rows 9-10. So we have three vertical lines of different lengths: B line length 6 (rows 3-8 inclusive). G line length 4 (rows 4-7). M line length 2 (rows 9-10). So the longest stick is B, next G, then M. The output grid is a 6x6 square: B outermost, G next, M innermost. Indeed output grid is 6x6: B B B B B B; B G G G G B; B G M M G B; B G M M G B; B G G G G B; B B B B B B. That matches the nested shells: outermost B border, next G border inside, next M border inside. So the rule: For each color, we have a line of that color in the input. The length of the line determines the size of the shell. The longest line becomes the outermost shell, next longest inside, etc. The output is a square of size equal to the length of the longest line. Each shell is one cell thick. The colors are arranged from outermost to innermost according to line lengths. The innermost shell is the smallest line's color. The output grid is fully filled with shells; no background.

Thus the transformation: Identify all colored lines (vertical or horizontal?) In example, they are vertical lines. But maybe they could be horizontal lines? The metaphor says "sticks of different lengths — each a single pure color, each lying perfectly straight, no two alike." So each stick is a straight line of cells of a single color. They could be horizontal or vertical. The input grid has them scattered. The longest stick is the longest line of same color. The next longest is next. They are nested inside each other. The output is a square of nested shells, each one cell thick, with outermost color being the longest stick's color, next inside being next longest, etc. The innermost is the smallest stick's color. The size of the output square is equal to the length of the longest stick. The number of shells equals the number of sticks. The shells are nested: each shell is a border of the square of that color. The innermost shell is a border of a square of size equal to the length of the smallest stick? Wait the innermost shell is a border of a square of size equal to the length of the smallest stick? Let's examine Example 1: The smallest stick length is 2. The innermost shell is a 2x2 border? Actually the innermost shell in output is a 2x2 border of M. Let's check: The output 6x6: The innermost 2x2 area is M M in rows 3-4, columns 3-4? Wait let's index: Outer B border: row 1 all B, row 6 all B, col 1 all B, col 6 all B. Next G bor

We need to solve a grid transformation puzzle. We have a metaphorical description, training examples, and a test input grid. We need to produce the output grid.

We need to parse the puzzle: The description: "Across a dark field, azure gemstones lie scattered like fallen stars. But among them, two pillars of grey iron stand upright, and azure cornerstone jewels cap their tops and bottoms, forming the frame of a buried chest. Inside the chest, some compartments hold azure gems while others sit empty. The gems strewn outside the chest are fool's gold — glittering distractions left by wanderers. What to do: Find the two iron pillars rising from the darkness — they are the sides of the chest. Look for the azure cornerstones that seal each pillar's top and bottom; these mark where the lid begins and the base ends. Lift the chest out of the ground whole, leaving every scattered gem behind in the dirt. What you hold in your hands is the treasure — nothing more, nothing less."

So we have a grid with black background (.), azure gems (A), grey iron pillars (X), azure cornerstones (A? Wait azure cornerstones are also A? But azure is A. But maybe azure cornerstones are also A but at corners? But we need to differentiate? The description says azure cornerstones are A. But we also have azure gems inside chest. So maybe azure gems inside chest are A as well. So we need to identify the chest boundaries: two vertical pillars of grey iron (X) that are the sides of the chest. The chest is defined by its grey iron walls running vertically and its azure cornerstones and trim running horizontally across the top and bottom. So the chest is a rectangle defined by two vertical X columns and two horizontal A rows at top and bottom. Inside the chest, azure gems (A) may be present or empty (black). Outside the chest, azure gems are scattered (fool's gold). The transformation: "Lift the chest out of the ground whole, leaving every scattered gem behind in the dirt. What you hold in your hands is the treasure — nothing more, nothing less." So we need to extract the chest contents: the rectangle defined by the two X columns and the top and bottom A rows. The output grid should be the chest interior? Or the chest itself? Let's examine training example.

Example 1 Input and Output:

Input:
```
. A . . . . . . . . .
. . A . . . A . . . A
. . . . . . . . . A A
. . A . . . . . A . .
A . X . . . . . X . .
. . X . . A A . X . .
. . X . . . . . X . .
. . A . A . . . A . .
. A . . . . . . A A .
```
Output:
```
A . . . . . A
X . . . . . X
X . . A A . X
X . . . . . X
A . A . . . A
```

Let's analyze. Input grid size: 9 rows, 11 columns? Let's count: first row: ". A . . . . . . . . ." that's 11 columns. So 9x11 grid.

Output grid: 5 rows, 7 columns? Let's count: first row: "A . . . . . A" that's 7 columns. So output is 5x7.

We need to see how output relates to input. Let's map coordinates. We'll index rows 0-8, columns 0-10.

Input grid:

Row0: col0 '.', col1 'A', col2 '.', col3 '.', col4 '.', col5 '.', col6 '.', col7 '.', col8 '.', col9 '.', col10 '.'
Row1: ". . A . . . A . . . A" => col0 '.', col1 '.', col2 'A', col3 '.', col4 '.', col5 '.', col6 'A', col7 '.', col8 '.', col9 '.', col10 'A'
Row2: ". . . . . . . . . A A" => col0 '.', col1 '.', col2 '.', col3 '.', col4 '.', col5 '.', col6 '.', col7 '.', col8 '.', col9 'A', col10 'A'
Row3: ". . A . . . . . A . ." => col0 '.', col1 '.', col2 'A', col3 '.', col4 '.', col5 '.', col6 '.', col7 '.', col8 'A', col9 '.', col10 '.'
Row4: "A . X . . . . . X . ." => col0 'A', col1 '.', col2 'X', col3 '.', col4 '.', col5 '.', col6 '.', col7 '.', col8 'X', col9 '.', col10 '.'
Row5: ". . X . . A A . X . ." => col0 '.', col1 '.', col2 'X', col3 '.', col4 '.', col5 'A', col6 'A', col7 '.', col8 'X', col9 '.', col10 '.'
Row6: ". . X . . . . . X . ." => col0 '.', col1 '.', col2 'X', col3 '.', col4 '.', col5 '.', col6 '.', col7 '.', col8 'X', col9 '.', col10 '.'
Row7: ". . A . A . . . A . ." => col0 '.', col1 '.', col2 'A', col3 '.', col4 'A', col5 '.', col6 '.', col7 '.', col8 'A', col9 '.', col10 '.'
Row8: ". A . . . . . . A A ." => col0 '.', col1 'A', col2 '.', col3 '.', col4 '.', col5 '.', col6 '.', col7 '.', col8 'A', col9 'A', col10 '.'

Now output grid:

Row0: "A . . . . . A" => col0 'A', col1 '.', col2 '.', col3 '.', col4 '.', col5 '.', col6 'A'
Row1: "X . . . . . X" => col0 'X', col1 '.', col2 '.', col3 '.', col4 '.', col5 '.', col6 'X'
Row2: "X . . A A . X" => col0 'X', col1 '.', col2 '.', col3 'A', col4 'A', col5 '.', col6 'X'
Row3: "X . . . . . X" => col0 'X', col1 '.', col2 '.', col3 '.', col4 '.', col5 '.', col6 'X'
Row4: "A . A . . . A" => col0 'A', col1 '.', col2 'A', col3 '.', col4 '.', col5 '.', col6 'A'

So output is a 5x7 grid. Let's see if this corresponds to a subgrid of the input. Let's find the rectangle defined by the two X columns and the top and bottom A rows. In input, the X columns are at col2 and col8. The top A row is row0?

We need to solve a grid transformation puzzle. We have a metaphorical description: "dark ocean with azure bioluminescent plankton drifting randomly. A rectangular porthole: grey iron frame on left and right sides, azure brass fittings along top and bottom edges and at the four corners. Through the glass, azure sea-lights and dark water are visible. Find the porthole — grey iron sides and azure brass fittings — and capture only the sea view framed within. Bioluminescence outside the porthole is hull-side scatter; ignore it."

We have training example 1: Input grid and output grid. We need to deduce transformation rule. Then apply to test input.

We need to parse the training example. Let's rewrite the input and output grids with coordinates.

We have color key: .=black B=blue R=red G=green Y=yellow X=grey M=magenta O=orange A=azure W=maroon.

In training example 1, input grid is 10x? Let's count columns: Input lines:

1: ". A . . . . . . . . . ." -> 12 columns? Let's count: . (1) space A (2) space . (3) space . (4) space . (5) space . (6) space . (7) space . (8) space . (9) space . (10) space . (11) space . (12). Yes 12 columns.

Row 1: . A . . . . . . . . . .
Row 2: . . A . . . A . . . A
Row 3: . . . . . . . . . A A
Row 4: . . A . . . . . A . .
Row 5: A . X . . . . . X . .
Row 6: . . X . . A A . X . .
Row 7: . . X . . . . . X . .
Row 8: . . A . A . . . A . .
Row 9: . A . . . . . . A A .
Row 10: (not given? Wait there are 9 rows? Let's check: The input shows 9 lines? Actually the input shows 9 lines: lines 1-9. Let's recount: Provided input:

```
. A . . . . . . . . . .
. . A . . . A . . . A
. . . . . . . . . A A
. . A . . . . . A . .
A . X . . . . . X . .
. . X . . A A . X . .
. . X . . . . . X . .
. . A . A . . . A . .
. A . . . . . . A A .
```

Yes 9 rows, 12 columns.

Output grid:

```
A . . . . . A
X . . . . . X
X . . A A . X
X . . . . . X
A . A . . . A
```

That's 5 rows, 7 columns.

So transformation reduces grid size. We need to find rule.

Let's analyze input: The metaphor: "dark ocean with azure bioluminescent plankton drifting randomly. A rectangular porthole: grey iron frame on left and right sides, azure brass fittings along top and bottom edges and at the four corners. Through the glass, azure sea-lights and dark water are visible. Find the porthole — grey iron sides and azure brass fittings — and capture only the sea view framed within. Bioluminescence outside the porthole is hull-side scatter; ignore it."

So we need to find a rectangular region defined by grey iron sides (X) on left and right sides, azure brass fittings (A) along top and bottom edges and at four corners. The view inside is azure (A) and black (.).

So we need to locate a rectangle where the border is X on left/right sides and A on top/bottom edges and corners. Then output the interior of that rectangle (including the border? The output includes A and X? Let's examine output: It contains A and X. The output grid includes A and X. The output grid seems to be the rectangle including the border? Let's check.

In input, we have a rectangle of X and A. Let's locate it.

Input grid: Let's mark coordinates. We'll index rows 1-9, columns 1-12.

Row1: col1 '.', col2 'A', col3 '.', col4 '.', col5 '.', col6 '.', col7 '.', col8 '.', col9 '.', col10 '.', col11 '.', col12 '.'

Row2: col1 '.', col2 '.', col3 'A', col4 '.', col5 '.', col6 '.', col7 'A', col8 '.', col9 '.', col10 '.', col11 'A', col12 ?

Wait row2 has 12 columns: ". . A . . . A . . . A" -> col1 '.', col2 '.', col3 'A', col4 '.', col5 '.', col6 '.', col7 'A', col8 '.', col9 '.', col10 '.', col11 'A', col12? Actually there are 12 columns: after last A there is a space then nothing? Let's count: ". (1) space . (2) space A (3) space . (4) space . (5) space . (6) space A (7) space . (8) space . (9) space . (10) space A (11)". Wait we need 12 columns. Let's recount: The string ". . A . . . A . . . A" has 11 tokens? Let's count tokens: 1 '.'; 2 '.'; 3 'A'; 4 '.'; 5 '.'; 6 '.'; 7 'A'; 8 '.'; 9 '.'; 10 '.'; 11 'A'. That's 11 tokens. But earlier we counted 12 columns. Let's check row1: ". A . . . . . . . . . ." -> tokens: 1 '.'; 2 'A'; 3 '.'; 4 '.'; 5 '.'; 6 '.'; 7 '.'; 8 '.'; 9 '.'; 10 '.'; 11 '.'; 12 '.' -> 12 tokens. Row2 has 11 tokens? That seems inconsistent. Let's check the input again: maybe there is a trailing space or missing token. Let's re-evaluate the input lines:

Input:
```
. A . . . . . . . . . .
. . A . . . A . . . A
. . . . . . . . . A A
. . A . . . . . A . .

. . X . . . . . X . .
. . A . A . . . A . .
. A . . . . . . A A .
```

Row2: ". . A . . . A . . . A" -> 11 tokens. Row3: ". . . . . . . . . A A" -> 11 tokens. Row4: ". . A . . . . . A . ." -> 11 tokens. Row5: "A . X . . . . . X . ." -> 11 tokens. Row6: ". . X . . A A .

We need to solve a grid transformation puzzle. The description: "What you see: A golden river runs across the middle of the battlefield, dividing two kingdoms. Above the river, the Red Army has pitched its tents on certain squares. Below the river, the Blue Army holds its own positions. The rest of the land lies empty and dark. What to do: The war is over — the golden river dries up, and the two kingdoms merge into one. Wherever either army had claimed ground, the united banner of green now flies. Only the squares that neither army ever touched remain barren darkness. Every soldier, red or blue, becomes green in the new alliance. Grid details: The golden river is a single row splitting the world in half. The united kingdom is exactly the size of one half. Every plot of land answers one question: did anyone fight here? If so, it blooms green."

So the transformation: We have a grid with a "golden river" row that splits the grid into two halves. The top half contains red army positions (R). The bottom half contains blue army positions (B). The rest of the grid is empty (.). The output grid is the union of the two halves: any cell that had R or B becomes G. The rest remains . (black). The output grid size is the same as the input? Wait: The description says "The united kingdom is exactly the size of one half." That might mean the output grid is half the size of the input grid? Let's examine training examples to confirm.

Example 1 Input: Let's parse. Input grid lines:

1: . . . . .
2: . R R R .
3: . R . . .
4: R R R . R
5: Y Y Y Y Y
6: B B . . B
7: B B . B B
8: B . B . B
9: . B . B B

So input grid is 9 rows by 5 columns. The golden river is a single row splitting the world in half. Which row is the river? In the input, row 5 is Y Y Y Y Y. That seems to be the golden river row. So the top half is rows 1-4 (4 rows). The bottom half is rows 6-9 (4 rows). The output grid is 4 rows by 5 columns. Indeed, the output grid in Example 1 is:

G G . . G
G G G G G
G G G . G
G G G G G

That's 4 rows by 5 columns. So the output grid is the top half? Wait, the output grid is 4 rows by 5 columns. Which half? The top half? Let's check: The output grid's first row: G G . . G. Let's compare with the top half of input: rows 1-4. Row 1: . . . . . -> no R or B. But output row 1: G G . . G. That doesn't match. Let's examine the transformation: The output grid is the union of red and blue positions from both halves, but the output grid is the size of one half. But which half? The output grid seems to be the size of the top half (4 rows). But the output grid's first row has G G . . G. Let's see if that matches the union of red positions from top half and blue positions from bottom half, but projected onto the top half? Let's analyze.

We need to understand the mapping. The description: "The united kingdom is exactly the size of one half." That suggests that the output grid is the size of one half of the input grid. But which half? Possibly the top half? Or maybe the output grid is the size of the top half (the red side). But the output grid's first row has G G . . G. Let's see if that matches the union of red positions from the top half and blue positions from the bottom half, but only for the columns that correspond to the top half? Wait, the output grid is 4 rows by 5 columns. The input grid is 9 rows by 5 columns. The top half is 4 rows. The bottom half is 4 rows. The output grid is 4 rows. So the output grid is the size of one half. But which half? It could be the top half. But the output grid's first row: G G . . G. Let's see if that matches the union of red positions from the top half and blue positions from the bottom half, but only for the first row of the top half? Let's check.

Top half rows 1-4:

Row1: . . . . .
Row2: . R R R .
Row3: . R . . .
Row4: R R R . R

Bottom half rows 6-9:

Row6: B B . . B
Row7: B B . B B
Row8: B . B . B
Row9: . B . B B

Now, if we overlay the bottom half onto the top half, aligning row 6 with row 1, row 7 with row 2, etc. Then we would get a 4x5 grid where each cell is G if either the top half had R or the bottom half had B. Let's compute that overlay.

Row1 overlay: top row1: . . . . . ; bottom row6: B B . . B. So union: B B . . B -> G G . . G. That matches output row1: G G . . G. Good.

Row2 overlay: top row2: . R R R . ; bottom row7: B B . B B. Union: . R R R . OR B B . B B -> G G G G G? Let's compute: For each column:

col1: top ., bottom B -> G
col2: top R, bottom B -> G
col3: top R, bottom . -> G
col4: top R, bottom B -> G
col5: top ., bottom B -> G

So row2 overlay: G G G G G. Output row2: G G G G G. Good.

Row3 overlay: top row3: . R . . . ; bottom row8: B . B . B. Union: col1: . B -> G; col2: R . -> G; col3: . B -> G; col4: . . -> .; col5: . B -> G. So row3 overlay: G G G . G. Output row3: G G G . G. Good.

Row4 overlay: top row4: R R R . R ; bottom row9: . B . B B. Union: col1: R . -> G; col2: R B -> G; col3: R . -> G; col4: . B ->

We need to solve a grid transformation puzzle. We have training examples. We need to deduce the transformation rule. The puzzle description: "What you see: A nautical chart torn along a gold latitude line. The upper half marks reefs in red from one captain's survey; the lower marks reefs in blue from another's. Uncharted waters are blank on both. What to do: Stitch the charts together along the gold line and project both surveys onto a single map. Every cell where either captain spotted a reef is marked green for danger. Only waters clear on both surveys remain unmarked. The merged chart is the size of one half. Hazard cells are green; safe waters are blank."

So we have two halves: upper half (red cells) and lower half (blue cells). The input grid is a full grid that contains both halves? Let's examine training examples.

Example 1 Input: 10 rows? Let's count. Provided:

Input:
. . . . .
. R R R .
. R . . .
R R R . R
Y Y Y Y Y
B B . . B
B B . B B
B . B . B
. B . B B

Wait that's 9 rows? Let's count: row1: . . . . . (5 columns)
row2: . R R R . (5)
row3: . R . . . (5)
row4: R R R . R (5)
row5: Y Y Y Y Y (5)
row6: B B . . B (5)
row7: B B . B B (5)
row8: B . B . B (5)
row9: . B . B B (5)

So 9 rows, 5 columns. Output:

G G . . G
G G G G G
G G G . G
G G G G G

Output has 4 rows, 5 columns. So output is half the number of rows (9 -> 4? Actually 9/2 = 4.5, but output has 4 rows). So maybe the input grid is 2 halves stacked vertically: top half (rows 1-4) are red cells, bottom half (rows 5-8?) Actually bottom half maybe rows 5-8? But we have 9 rows, so maybe the middle row is the gold line? Wait the description: "nautical chart torn along a gold latitude line. The upper half marks reefs in red from one captain's survey; the lower marks reefs in blue from another's. Uncharted waters are blank on both." So the input grid might contain both halves: top half (rows 1-? maybe 4) with red cells, bottom half (rows 5-? maybe 8) with blue cells. The middle row (row 5) might be the gold line? But row 5 is Y Y Y Y Y. That is all Y's. Y is yellow. The color key: Y=yellow. So maybe Y indicates the gold line. So the input grid has a row of Y's that marks the gold line. The top half (rows above Y) contains red cells (R). The bottom half (rows below Y) contains blue cells (B). The Y row is the gold line. The output grid is the size of one half (i.e., the number of rows above Y). The hazard cells are green where either captain spotted a reef. So we need to overlay the red cells from the top half and the blue cells from the bottom half onto the same grid of size equal to the top half. For each cell, if either the red cell or the blue cell is present (i.e., R or B), then output G. If both are absent (i.e., '.' in both), output '.'.

But we need to align the bottom half onto the top half. The bottom half might be reversed? Let's examine Example 1 to confirm.

Example 1 Input: 9 rows, 5 columns. Row 5 is Y Y Y Y Y. So top half rows 1-4: rows 1-4. Bottom half rows 6-9: rows 6-9. So top half has 4 rows, bottom half has 4 rows. Output has 4 rows. So we overlay row 1 of top half with row 6 of bottom half? Or row 1 with row 9? Let's test.

Top half rows:

Row1: . . . . .
Row2: . R R R .
Row3: . R . . .
Row4: R R R . R

Bottom half rows:

Row6: B B . . B
Row7: B B . B B
Row8: B . B . B
Row9: . B . B B

Now overlay: For each column, if either top cell is R or bottom cell is B, output G. Let's compute.

We need to align bottom half rows with top half rows. Which mapping? Let's test mapping row6 to row1, row7 to row2, row8 to row3, row9 to row4. That would overlay bottom half reversed? Actually row6 is the first row below Y. So maybe we overlay row6 onto row1? Let's test.

Compute overlay row1: top row1: . . . . . ; bottom row6: B B . . B. So cells: col1: top '.' bottom 'B' => G. col2: '.' + 'B' => G. col3: '.' + '.' => '.' (both '.'), col4: '.' + '.' => '.', col5: '.' + 'B' => G. So row1 output: G G . . G. That matches output row1: G G . . G. Good.

Row2: top row2: . R R R . ; bottom row7: B B . B B. Overlay: col1: '.' + 'B' => G. col2: 'R' + 'B' => G. col3: 'R' + '.' => G. col4: 'R' + 'B' => G. col5: '.' + 'B' => G. So row2 output: G G G G G. That matches output row2: G G G G G.

Row3: top row3: . R . . . ; bottom row8: B . B . B. Overlay: col1: '.' + 'B' => G. col2: 'R' + '.' => G. col3: '.' + 'B' => G. col4: '.' + '.' => '.'; col5: '.' + 'B' => G. So row3 output: G G G . G. That matches output row3: G G G . G.

Row4: top row4: R R R . R ; bottom row9: . B . B B. Overlay: col1: 'R' + '.' => G. col2: 'R' + 'B' => G. col3: 'R' + '.' => G. col4: '.' + 'B' => G. col5: 'R' + 'B' => G. So row4 output: G G G G G. That matches output row4: G G G G G.

Thus mapping is row6->row1, row7->row2, row8->row3, row9->row4. So bottom half is aligned directly below the Y line, but we overlay them onto the top half by aligning row6 with row1, etc. So basically we overlay the bottom half

We need to solve a grid transformation puzzle. We have training examples. We need to deduce the rule. Let's parse the problem statement.

We have a metaphorical description: "What you see: A circuit board split by a golden bus bar. The upper channel carries red HIGH signals at certain nodes; the lower carries blue HIGH signals at others. Unpowered nodes sit at LOW on both sides. What to do: The bus bar routes both channels into a shared OR gate array. Each gate outputs green HIGH if either input is HIGH. Only nodes where both inputs are LOW remain off. Grid details: The output array matches one channel's dimensions. HIGH outputs are green; LOW nodes are black."

So we have two channels: upper channel (red) and lower channel (blue). The grid input includes both channels? The input grid includes both red and blue cells. The output grid is green where either red or blue is present (i.e., OR). But the output grid matches one channel's dimensions. Which channel? The output array matches one channel's dimensions. The output grid is smaller than the input? Let's examine training examples.

Example 1 Input grid: Let's list coordinates. The input grid appears to be 9 rows? Let's count: Provided lines:

1: . . . . .
2: . R R R .
3: . R . . .
4: R R R . R
5: Y Y Y Y Y
6: B B . . B
7: B B . B B
8: B . B . B
9: . B . B B

So 9 rows, each row has 5 columns. So input grid is 9x5. Output grid: Provided lines:

1: G G . . G
2: G G G G G
3: G G G . G
4: G G G G G

So output grid is 4x5. So output grid has 4 rows, 5 columns. So output grid matches one channel's dimensions. Which channel? The upper channel maybe? Let's examine the input: The first 4 rows (rows 1-4) contain red cells (R). The next row (row 5) is Y Y Y Y Y (yellow). Then rows 6-9 contain blue cells (B). So the input grid is split by a golden bus bar: row 5 is Y Y Y Y Y (gold). So the upper channel is rows 1-4 (red). The lower channel is rows 6-9 (blue). The bus bar is row 5 (yellow). So the output grid matches one channel's dimensions: maybe the upper channel's dimensions: 4 rows x 5 columns. Indeed output grid is 4x5. So output grid is the OR of the red and blue channels, but only for the positions that correspond to the upper channel? Wait, but the lower channel has 4 rows as well (rows 6-9). So both channels have 4 rows each. So output grid matches one channel's dimensions: either upper or lower. But the output grid is 4x5. So we need to compute OR of red and blue at each corresponding position? But the red and blue are in separate halves of the grid. So we need to overlay them? The bus bar routes both channels into a shared OR gate array. Each gate outputs green HIGH if either input is HIGH. Only nodes where both inputs are LOW remain off. So we need to align the two channels: The upper channel's nodes correspond to the lower channel's nodes? The bus bar splits them but then routes them into a shared OR gate array. So we need to overlay the two halves: For each position (i,j) in the output grid, we look at the corresponding position in the upper channel (row i, col j) and the lower channel (row i+? maybe offset). But the lower channel is below the bus bar. So we need to align them: The lower channel's row 1 corresponds to the upper channel's row 1? Or maybe the lower channel's row 1 corresponds to the upper channel's row 1? But the lower channel's rows are 6-9. So we need to map them to 1-4. So we need to subtract 5? Actually row 6 corresponds to row 1 of lower channel. So we need to align them: For each i from 1 to 4, we take upper channel row i and lower channel row i+5? Wait, row 6 is lower channel row 1. So mapping: lower row index = i+5. So we overlay them: For each i in 1..4, j in 1..5, we look at input[i][j] (upper channel) and input[i+5][j] (lower channel). Then we compute OR: if either is R or B, output G. If both are '.' (LOW), output '.'.

But we need to confirm with example 1. Let's compute manually.

Example 1 Input:

Rows 1-4 (upper channel):

Row1: . . . . .
Row2: . R R R .
Row3: . R . . .
Row4: R R R . R

Rows 6-9 (lower channel):

Row6: B B . . B
Row7: B B . B B
Row8: B . B . B
Row9: . B . B B

Now compute OR for each position:

Row1: upper: . . . . . ; lower: B B . . B
- col1: upper '.' lower 'B' => G
- col2: '.' + 'B' => G
- col3: '.' + '.' => '.' (both low)
- col4: '.' + '.' => '.'
- col5: '.' + 'B' => G

So row1 output: G G . . G. That matches output row1: G G . . G. Good.

Row2: upper: . R R R . ; lower: B B . B B
- col1: '.' + 'B' => G
- col2: 'R' + 'B' => G
- col3: 'R' + '.' => G
- col4: 'R' + 'B' => G
- col5: '.' + 'B' => G

So row2 output: G G G G G. Matches.

Row3: upper: . R . . . ; lower: B . B . B
- col1: '.' + 'B' => G
- col2: 'R' + '.' => G
- col3: '.' + 'B' => G
- col4: '.' + '.' => '.'
- col5: '.' + 'B' => G

So row3 output: G G G . G. Matches.

Row4: upper: R R R . R ; lower: . B . B B
- col1: 'R' + '.' => G
- col2: 'R' + 'B' => G
- col3: 'R' + '.' => G
- col4: '.' + 'B'

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A kitchen counter divided by a strip of saffron garnish. Above it, dollops of paprika reduction sit in some compartments of a mold; below, pools of blueberry coulis fill other compartments. Some compartments on each side are empty. What to do: Remove the saffron divider and fold both sauces into a single mold of the same compartment layout. Any compartment that received flavor from either sauce turns into a mature green pesto. Only compartments that were empty in both halves remain clean. The resulting mold has half the rows. Filled compartments are green; empty ones are bare."

We have training example 1: Input grid and output grid. We need to deduce transformation rule.

We have test input grid. We need to produce output grid.

We need to parse the training example to understand mapping.

Let's analyze training example 1.

Input grid:

```
. . . . .
. R R R .
. R . . .
R R R . R
Y Y Y Y Y
B B . . B
B B . B B
B . B . B
. B . B B
```

We need to interpret grid: Each cell is a color code: '.' black, 'R' red, 'Y' yellow, 'B' blue, etc. The grid is 9 rows? Let's count: Provided lines: 9 lines. Each line has 5 columns? Let's check: first line ". . . . ." -> 5 columns. So grid is 9x5.

Output grid:

```
G G . . G
G G G G G
G G . G
G G G G G
```

Wait output grid lines: 4 lines? Let's count: Provided lines: "G G . . G" (5 columns), "G G G G G" (5 columns), "G G . G" (4 columns?), "G G G G G" (5 columns). That seems inconsistent. Let's double-check: The output grid lines: "G G . . G" (5 columns). "G G G G G" (5). "G G . G" (4). "G G G G G" (5). That seems wrong. Maybe there is a formatting issue. Let's examine the training example again: Provided:

```
Output:
G G . . G
G G G G G
G G . G
G G G G G
```

It might be that the output grid is 4 rows, but the third row has only 4 columns? That seems unlikely. Maybe there is a missing space or a misprint. Let's analyze the transformation conceptually: The metaphor says: "kitchen counter divided by a strip of saffron garnish. Above it, dollops of paprika reduction sit in some compartments of a mold; below, pools of blueberry coulis fill other compartments. Some compartments on each side are empty. Remove the saffron divider and fold both sauces into a single mold of the same compartment layout. Any compartment that received flavor from either sauce turns into a mature green pesto. Only compartments that were empty in both halves remain clean. The resulting mold has half the rows. Filled compartments are green; empty ones are bare."

So we have a grid that is split horizontally by a saffron divider (maybe a row of 'X' or something). The top half has some colored cells (paprika reduction) and bottom half has some colored cells (blueberry coulis). We need to combine them: For each cell, if either top or bottom cell is colored (i.e., not '.'), then output cell is green 'G'. If both are '.' then output cell remains '.'.

Also, the resulting mold has half the rows. That means we combine two halves into one grid with half the number of rows. So if input grid has 2n rows, output grid has n rows. Each output row corresponds to a pair of input rows: top row and bottom row? Wait: The metaphor says "kitchen counter divided by a strip of saffron garnish." That could be a horizontal divider row of saffron (maybe 'X' or 'Y' or something). But the input grid may have a row of 'X' or 'Y' that acts as divider. But the training example input grid: Let's examine the rows:

Row1: ". . . . ."
Row2: ". R R R ."
Row3: ". R . . ."
Row4: "R R R . R"
Row5: "Y Y Y Y Y"
Row6: "B B . . B"
Row7: "B B . B B"
Row8: "B . B . B"
Row9: ". B . B B"

We need to identify a divider row. Row5 is "Y Y Y Y Y" - all Y. That could be saffron garnish? But Y is yellow, not saffron. But maybe saffron is represented by Y? But Y is yellow. But saffron is a golden color, maybe Y. So row5 might be the divider. The top half is rows 1-4, bottom half rows 6-9. Row5 is the divider. So we remove the divider and combine top and bottom halves.

Now we need to combine each cell: For each column, we have top cell from row1-4 and bottom cell from row6-9. But we need to combine them row-wise: For each pair of rows (top row i and bottom row i?), we combine them into one output row. But the top half has 4 rows, bottom half has 4 rows. So we can pair row1 with row6, row2 with row7, row3 with row8, row4 with row9. That would produce 4 output rows. That matches output grid having 4 rows. Good.

Now we need to compute each output cell: If either top cell or bottom cell is colored (not '.'), output 'G', else '.'.

Let's test this with the training example.

We need to map each pair:

- Pair 1: Row1 (top) = ". . . . ."
  Row6 (bottom) = "B B . . B"

Combine: For each column:
col1: top '.' bottom 'B' -> G
col2: top '.' bottom 'B' -> G
col3: top '.' bottom '.' -> '.' (since both '.'? Wait bottom '.'? Row6 col3 is '.'? Row6: "B B . . B"

We need to parse the problem. We have a grid transformation puzzle. The description: "Two architectural floor plans separated by a golden binding strip. The upper plan draws walls in red drafting ink; the lower plan draws walls in blue. Open spaces in each plan are empty. Remove the binding and overlay the plans on the light table. Any cell where either plan specifies a wall becomes solid green in the composite. Only spaces open in both plans remain empty. The composite plan has the footprint of one floor. Solid walls are green; open spaces are unmarked."

So we have two input grids? Wait: The training example shows Input: a grid of 10 rows? Let's examine Example 1 Input:

```
. . . . .
. R R R .
. R . . .
R R R . R
Y Y Y Y Y
B B . . B
B B . B B
B . B . B
. B . B B
```

Wait that's 9 rows? Let's count: Row1: ". . . . ." (5 columns). Row2: ". R R R ." (5). Row3: ". R . . ." (5). Row4: "R R R . R" (5). Row5: "Y Y Y Y Y" (5). Row6: "B B . . B" (5). Row7: "B B . B B" (5). Row8: "B . B . B" (5). Row9: ". B . B B" (5). So 9 rows, 5 columns.

Output:

```
G G . . G
G G G G G
G G G . G
G G G G G
```

That's 4 rows, 5 columns. So the output is smaller. So the transformation is not just overlaying two grids of same size. The input seems to contain two floor plans separated by a golden binding strip. The golden binding strip might be the row of Y's? Wait Y is yellow. In the input, row5 is "Y Y Y Y Y". That might be the golden binding strip. The upper plan is above that row, the lower plan is below that row. The upper plan uses red walls (R). The lower plan uses blue walls (B). The Y row is the binding strip. The output is the composite plan: any cell where either plan has a wall becomes green. Only cells open in both remain empty. So we overlay the two plans ignoring the binding row. But the output grid is smaller: we need to combine the two halves into one grid. But the output grid has 4 rows, not 8. Wait the upper plan has 4 rows (rows 1-4). The lower plan has 4 rows (rows 6-9). So overlaying them would produce 4 rows? But we need to overlay them: For each cell position (i,j) in the output, we look at the corresponding cell in the upper plan (row i) and the lower plan (row i). But the lower plan's rows are offset? Wait the lower plan has 4 rows, but we overlay them onto the same positions as the upper plan. So we need to align them row-wise: row1 of upper plan with row1 of lower plan? But the lower plan's row1 is row6 of input. So we overlay row1 of upper plan with row1 of lower plan. That yields 4 rows. That matches output: 4 rows. So the output grid is the overlay of the two halves, ignoring the binding row. So we overlay each cell: if either is a wall (R or B), output G. If both are empty (.), output . (empty). But we also need to consider that the lower plan may have B walls, but the upper plan may have R walls. So we treat both as walls. So the rule: For each cell (i,j) in the output, if either the upper plan cell (i,j) is R or the lower plan cell (i,j) is B, output G. Else output . (empty). That seems to produce the output.

Let's test with Example 1: We'll overlay row1 of upper plan: ". . . . ." with row1 of lower plan: "B B . . B". For each column: col1: upper ., lower B => G. col2: upper ., lower B => G. col3: upper ., lower . => .? Wait lower is '.'? Actually row6 col3 is '.'? Row6: "B B . . B" => col3 '.' => no wall. So both empty => output '.'? But output row1 col3 is '.'? Let's check output row1: "G G . . G". Yes col3 '.' matches. col4: upper ., lower '.' => '.' output '.'? But output row1 col4 '.'? Yes. col5: upper ., lower B => G. So row1 matches.

Row2: upper plan row2: ". R R R ." ; lower plan row2: "B B . B B". Let's overlay: col1: upper '.' lower 'B' => G. col2: upper 'R' lower 'B' => G. col3: upper 'R' lower '.' => G. col4: upper 'R' lower 'B' => G. col5: upper '.' lower 'B' => G. Output row2: "G G G G G" matches.

Row3: upper row3: ". R . . ." ; lower row3: "B . B . B". Overlay: col1: '.' + 'B' => G. col2: 'R' + '.' => G. col3: '.' + 'B' => G. col4: '.' + '.' => '.'? Wait lower row3 col4 '.'? Row8: "B . B . B" => col4 '.' => yes. So output '.'? But output row3 col4 is '.'? Let's check output row3: "G G G . G". Yes col4 '.' matches. col5: '.' + 'B' => G. So row3 matches.

Row4: upper row4: "R R R . R" ; lower row4: ". B . B B". Overlay: col1: 'R' + '.' => G. col2: 'R' + 'B' => G. col3: 'R' + '.' => G. col4: '.' + 'B' => G. col5: 'R' + 'B' => G. Output row4: "G G G G G" matches.

So rule works.

Now we need to apply to test input.

Test Input:

```
. R R R R
. . . R .
. R . . .
R R R . R
Y Y Y Y Y
. . B . .
. . . . B
B . . B B
. . . . B
```

Let's parse: 9 rows, 5 columns. Row1: ". R R R R" ; Row2: ". . . R ." ; Row3: ". R . . ." ; Row4: "R R R . R" ; Row5: "Y Y Y Y Y" ; Row6: ". . B . ." ; Row7: ". . . . B" ; Row8: "B . . B B" ; Row9: ". . . . B"

So upper plan: rows 1-4. Lower plan: rows 6-9. Binding row: row5 Y's.

We need to solve a grid transformation puzzle. The description: "What you see: A war table split by a gold command ribbon. Above, one scout's report marks enemy positions in red. Below, the other scout's report marks positions in blue. Unobserved cells are blank in both. What to do: Remove the ribbon and merge both intelligence reports onto one tactical map. Every cell flagged by at least one scout turns green for 'confirmed presence.' Only cells missed by both remain unmarked. The tactical map matches one scout report's dimensions. Occupied cells are green; unconfirmed cells are blank."

So we have two grids: one above the ribbon (red cells) and one below (blue cells). The output grid is the same size as one of the scout reports (the top or bottom? The description says "The tactical map matches one scout report's dimensions." So the output grid is the same size as the top or bottom grid. The input grid is a single grid that contains both top and bottom parts separated by a row of Y's? Wait, the training examples show input grids that have a row of Y's in the middle. Let's examine Example 1 input:

Example 1 Input:
```
. . . . .
. R R R .
. R . . .
R R R . R
Y Y Y Y Y
B B . . B
B B . B B
B . B . B
. B . B B
```
So the input grid is 9 rows by 5 columns. The first 4 rows are the red scout's report (top). Then a row of Y Y Y Y Y (the gold command ribbon). Then 5 rows of blue scout's report (bottom). The output grid is 4 rows by 5 columns: 
```
G G . . G
G G G G G
G G G . G
G G G G G
```
So the output grid is the same size as the top part (4 rows). The output grid shows green cells where either red or blue had a cell. But note that the bottom part has 5 rows, but the output only has 4 rows. So we only consider the top part's dimensions. But we need to merge the two reports onto one map of that size. So we overlay the bottom part onto the top part, aligning them by columns but maybe aligning rows? Wait, the bottom part has 5 rows, but the top part has 4 rows. So how do we overlay? The output grid has 4 rows. So we need to overlay the bottom part onto the top part by aligning the bottom part's rows with the top part's rows? But the bottom part has 5 rows, so maybe we only consider the first 4 rows of the bottom part? Or maybe we consider the bottom part's rows that correspond to the top part's rows? Let's examine Example 1 to deduce the overlay logic.

Example 1 Input: top 4 rows, bottom 5 rows. Output 4 rows. Let's overlay bottom part onto top part by aligning the bottom part's rows with the top part's rows starting from the top? That would mean we overlay bottom rows 1-4 onto top rows 1-4. But bottom part has 5 rows, so row 5 of bottom part is not used. Let's test: bottom part rows:

Row 5: B B . . B
Row 6: B B . B B
Row 7: B . B . B
Row 8: . B . B B

Wait, bottom part has 5 rows: rows 6-10? Actually the input grid has 9 rows: rows 1-4 top, row 5 Y's, rows 6-10 bottom. So bottom part rows 6-10: 5 rows. Let's index them as bottom row 1 = row 6 of input, bottom row 2 = row 7, bottom row 3 = row 8, bottom row 4 = row 9, bottom row 5 = row 10? Wait, there are only 9 rows in input. Let's recount: Example 1 input lines:

1: . . . . .
2: . R R R .
3: . R . . .
4: R R R . R
5: Y Y Y Y Y
6: B B . . B
7: B B . B B
8: B . B . B
9: . B . B B

So there are 9 rows. So top part has 4 rows (rows 1-4). Bottom part has 4 rows (rows 6-9). Wait, row 5 is Y's. So bottom part has 4 rows, not 5. So the bottom part matches the top part's dimensions. So the output grid is 4 rows. Good. So the bottom part has same number of rows as top part. So the output grid is 4 rows. So we overlay bottom part onto top part by aligning rows 1-4 of bottom part with rows 1-4 of top part. That seems plausible.

Now let's test the overlay logic: For each cell, if either top or bottom has a non-blank (i.e., R or B), then output G. If both are blank, output blank. Let's test with Example 1.

Top part:
Row1: . . . . .
Row2: . R R R .
Row3: . R . . .
Row4: R R R . R

Bottom part:
Row1: B B . . B
Row2: B B . B B
Row3: B . B . B
Row4: . B . B B

Now overlay:

Row1: top: . . . . . ; bottom: B B . . B => cells: col1: top blank, bottom B => G; col2: top blank, bottom B => G; col3: top blank, bottom . => blank; col4: top blank, bottom . => blank; col5: top blank, bottom B => G. So row1 output: G G . . G. That matches output row1.

Row2: top: . R R R . ; bottom: B B . B B => col1: top blank, bottom B => G; col2: top R, bottom B => G; col3: top R, bottom . => G; col4: top R, bottom B => G; col5: top blank, bottom B => G. So row2 output: G G G G G. That matches output row2.

Row3: top: . R . . . ; bottom: B . B . B => col1: top blank, bottom B => G; col2: top R, bottom . => G; col3: top ., bottom B => G; col4: top ., bottom . => blank; col5: top ., bottom B => G. So row3 output: G G G . G. That matches output row3.

Row4: top: R R R . R ; bottom: . B . B B => col1: top R, bottom . => G; col2: top R, bottom B

We need to solve a grid transformation puzzle. The description: "Scattered across a dark landscape, small herds of mysterious grey animals huddle together. Some travel in pairs, some in trios, and some in groups of four. Each herd keeps to itself, never touching another. What to do: A naturalist arrives to catalog the wildlife. She identifies each herd by counting its members, then paints them with a tag color revealing their species: the smallest pairs share one color, the middle-sized trios another, and the largest bands of four a third. The empty wilderness stays untouched. Grid details: The dark terrain remains as-is. Every grey animal receives its species tag — a new coat color determined solely by how many companions share its herd. No creatures appear or vanish; only their coats change."

So we have a grid with '.' representing black (dark terrain). 'X' representing grey animals. We need to identify connected components of X's (connected orthogonally? Likely orthogonal adjacency). Each component size: 2, 3, or 4. Then we recolor each X in that component to a color based on size: pairs -> one color, trios -> another, groups of four -> another. The colors used in example: In Example 1, input had X's. Output shows R, G, B. Let's analyze mapping.

Example 1 Input grid 10x10. Let's parse.

Input grid lines:

1: . . . . . . . . . .
2: . . . . . . . . . .
3: . X X X . . . X . .
4: . . . . . . . X . .
5: . . . . . . . . . .
6: . . . X X . . . . .
7: . . . X . . . . . .
8: . . . . . . . X . .
9: . X X . . . X X X .
10: . X X . . . . . . .

Output grid lines:

1: . . . . . . . . . .
2: . . . . . . . . . .
3: . R R R . . . G . .
4: . . . . . . . G . .
5: . . . . . . . . . .
6: . . . R R . . . . .
7: . . . R . . . . . .
8: . . . . . . . B . .
9: . B B . . . B B B .
10: . B B . . . . . . .

We need to map each component.

Let's identify components in input.

Input X positions:

Row3: col2,3,4 (three X's contiguous horizontally). Row3 col8 (X). Row4 col8 (X). Row6 col4,5 (two X's). Row7 col4 (X). Row8 col8 (X). Row9 col2,3 (two X's). Row9 col7,8,9 (three X's). Row10 col2,3 (two X's).

Also Row3 col8 and Row4 col8 are adjacent vertically, so they form a component of size 2? Wait Row3 col8 and Row4 col8 are adjacent vertically, yes. So component of size 2.

Row6 col4 and Row6 col5 adjacent horizontally, size 2. Row7 col4 adjacent to Row6 col4 vertically, so that extends component to size 3? Wait Row6 col4 is part of component with Row6 col5. Row7 col4 is adjacent to Row6 col4, so component size 3. So that component is 3 X's: (6,4), (6,5), (7,4). Good.

Row9 col2,3 adjacent horizontally, size 2. Row10 col2,3 adjacent horizontally, and also adjacent vertically to row9 col2,3? Row9 col2 adjacent to row10 col2, row9 col3 adjacent to row10 col3. So all four X's (9,2),(9,3),(10,2),(10,3) form a component of size 4. Good.

Row9 col7,8,9 adjacent horizontally, size 3. Row8 col8 adjacent to row9 col8 vertically, so that extends component to size 4? Wait row8 col8 is X. So component includes (8,8),(9,7),(9,8),(9,9). That's 4 X's. So component size 4.

Row3 col2,3,4 is a component of size 3.

Row3 col8 and Row4 col8 is component size 2.

So we have components sizes: 3, 2, 3, 4, 4, 3? Wait we counted: (3,2-4) size 3; (3,8-4,8) size 2; (6,4-6,5-7,4) size 3; (9,2-10,3) size 4; (8,8-9,7-9,9) size 4; (9,7-9,9-8,8) we already counted; (9,7-9,9-8,8) is same component. So we have 3 components of size 3? Let's list all components:

1. Component A: (3,2),(3,3),(3,4) size 3.
2. Component B: (3,8),(4,8) size 2.
3. Component C: (6,4),(6,5),(7,4) size 3.
4. Component D: (9,2),(9,3),(10,2),(10,3) size 4.
5. Component E: (8,8),(9,7),(9,8),(9,9) size 4.

So we have 2 components of size 2, 2 components of size 3, 2 components of size 4. Wait we counted 2 of size 2? Actually we have only one component of size 2: B. Did we miss any other size 2? Let's double-check: Are there any other X's not part of these components? Let's list all X coordinates:

Row3: col2,3,4,8
Row4: col8
Row6: col4,5
Row7: col4
Row8: col8
Row9: col2,3,7,8,9
Row10: col2,3

We accounted for all: 3+2+3+4+4 = 16 X's. Let's count: 3+2+3+4+4 = 16. Yes.

So we have 1 component of size 2, 2 components of size 3, 2 components of size 4. Wait we counted 2 components of size 3: A and C. Yes.

Now output mapping: Let's see colors.

Component A (size 3) output: row3 col2-4 are R R R. So size 3 -> R.

Component B (size 2) output: row3 col8 and row4 col8 are G G. So size 2 -> G.

Component C (size 3) output: row6 col4,5,7,4 are R R R. So size 3 -> R.

Component D (size 4) output: row9 col2,3,10,2,3 are B B B B. So size 4 -> B.

Component E (size 4) output: row8 col8, row9 col7,8,9 are B B B B. So size 4 -> B.

Thus mapping: size 2 -> G, size 3 -> R, size 4 -> B.

So the rule: For each connected component of X's, recolor all X's in that component to a color based on component size: size 2 -> G, size 3 -> R, size 4 -> B. The colors are fixed ma

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A dark slide dotted with pale, unstained cell colonies of varying sizes. What to do: Apply the appropriate fluorescent marker to each colony based on the number of cells it contains. Smaller fusions glow one hue, mid-sized another, and the largest yet another. Grid details: Grid dimensions match the input. Black background remains. Each pale colony is recolored with its size-appropriate fluorescent dye."

We have training example 1: Input grid 10x10 with '.' and 'X' cells. Output grid has '.' and colored cells: R, G, B. So we need to map each connected component of X's to a color based on size. The mapping: small -> R? mid -> G? large -> B? Let's analyze.

Example 1 Input:

Row 0: . . . . . . . . . .
Row 1: . . . . . . . . . .
Row 2: . X X X . . . X . .
Row 3: . . . . . . . X . .
Row 4: . . . . . . . . . .
Row 5: . . . X X . . . . .
Row 6: . . . X . . . . . .
Row 7: . . . . . . . X . .
Row 8: . X X . . . X X X .
Row 9: . X X . . . . . . .

Let's identify connected components of X's. Use 4-neighbor connectivity? Likely 4-neighbor (up/down/left/right). Let's map.

Component 1: At (2,1),(2,2),(2,3) contiguous horizontally. Also (3,7) is separate? Wait (2,7) is X. Let's list all X coordinates:

Row 2: (2,1),(2,2),(2,3),(2,7)
Row 3: (3,7)
Row 5: (5,3),(5,4)
Row 6: (6,3)
Row 7: (7,7)
Row 8: (8,1),(8,2),(8,6),(8,7),(8,8)
Row 9: (9,1),(9,2)

Also maybe (8,6) is X. Yes.

Now connectivity:

Component A: (2,1),(2,2),(2,3) are connected horizontally. Are they connected to any other X? Check adjacency: (3,1) is ., (1,1) ., (2,0) ., (2,4) . So isolated component of size 3.

Component B: (2,7),(3,7),(7,7),(8,6),(8,7),(8,8),(7,7) etc. Let's see connectivity: (2,7) adjacent to (3,7). (3,7) adjacent to (2,7) and (4,7) ., (3,6) ., (3,8) . So component B includes (2,7),(3,7). Also (7,7) is far away, not connected. So component B size 2.

Component C: (5,3),(5,4),(6,3). These are connected: (5,3) adjacent to (5,4) and (6,3). (6,3) adjacent to (5,3). So component C size 3.

Component D: (7,7) alone? Wait (7,7) is X. Adjacent to (6,7) ., (8,7) X, (7,6) ., (7,8) . So (7,7) connects to (8,7). So component D includes (7,7),(8,7). Also (8,6) and (8,8) adjacent to (8,7). So component D includes (7,7),(8,7),(8,6),(8,8). Also (8,6) adjacent to (8,7). (8,8) adjacent to (8,7). So component D size 4.

Component E: (8,1),(8,2),(9,1),(9,2). These are connected: (8,1) adjacent to (8,2),(9,1). (8,2) adjacent to (8,1),(9,2). (9,1) adjacent to (8,1),(9,2). (9,2) adjacent to (8,2),(9,1). So component E size 4.

So we have components sizes: 3,2,3,4,4. Output grid shows colors:

Let's map output grid:

Row 0: all .
Row 1: all .
Row 2: . R R R . . . G . .
Row 3: . . . . . . . G . .
Row 4: all .
Row 5: . . . R R . . . . .
Row 6: . . . R . . . . . .
Row 7: . . . . . . . B . .
Row 8: . B B . . . B B B .
Row 9: . B B . . . . . . .

So mapping: component A (size 3) at (2,1-3) is colored R. So size 3 -> R.

Component B (size 2) at (2,7),(3,7) is colored G. So size 2 -> G.

Component C (size 3) at (5,3),(5,4),(6,3) is colored R. So size 3 -> R.

Component D (size 4) at (7,7),(8,6),(8,7),(8,8) is colored B. So size 4 -> B.

Component E (size 4) at (8,1),(8,2),(9,1),(9,2) is colored B. So size 4 -> B.

Thus mapping: size 2 -> G, size 3 -> R, size 4 -> B. Are there any other sizes? Not in this example. So we need to deduce mapping for other sizes maybe.

But we only have one training example. We need to apply to test input. We need to identify components of X's, compute sizes, and assign colors accordingly. But we need to know mapping for all possible sizes that may appear in test input. The test input may have components of various sizes. We need to guess mapping. The puzzle description: "Apply the appropriate fluorescent marker to each colony based on the number of cells it contains. Smaller fusions glow one hue, mid-sized another, and the largest yet another." So there are three categories: small, medium, large. In example, small size 2 -> G, medium size 3 -> R, large size 4 -> B. But is that the mapping? Wait small -> G, medium -> R, large -> B. But we need to confirm if small is 2, medium 3, large 4. But maybe small is 1? But there is no component of size 1 in example. But we can guess that size 1 would be maybe R? But we need to deduce mapping from example.

Let's analyze the mapping: The output uses colors R, G, B. The mapping might be: small -> G, medium -> R, large -> B. But we need to confirm if the mapping is consistent with typical color assignment: maybe small -> R, medium -> G, large -> B. But example shows size 2 -> G, size 3 -> R, size 4 -> B. So small (size 2) -> G, medium (size 3) -> R, large (size 4) -> B. That seems plausible.

But we need to consider if there might be other sizes like 1, 5, etc. The puzzle might have only sizes 1-4. But we need to guess map

We need to solve a grid transformation puzzle. We have training examples. We need to deduce the rule. Let's analyze.

We have a grid of 10x10 (since examples show 10 rows, 10 columns). Input uses '.' for black (empty). 'X' for grey. Output uses colors: R, G, B, etc. The rule: "Count the stars in each cluster and render them in the false-color palette assigned to that membership tier." The metaphor: "dark sky field with faint grey star clusters of various sizes. Count the stars in each cluster and render them in the false-color palette assigned to that membership tier." So we need to identify clusters of X's (connected components). Count number of X's in each cluster. Then assign a color based on membership tier. The membership tier likely refers to cluster size categories. The palette mapping: maybe small clusters -> B, medium -> G, large -> R, etc. Let's analyze training examples to deduce mapping.

Example 1 Input: Let's parse.

Example 1 Input grid:

Row1: . . . . . . . . . .
Row2: . . . . . . . . . .
Row3: . X X X . . . X . .
Row4: . . . . . . . X . .
Row5: . . . . . . . . . .
Row6: . . . X X . . . . .
Row7: . . . X . . . . . .
Row8: . . . . . . . X . .
Row9: . X X . . . X X X .
Row10: . X X . . . . . . .

Let's mark coordinates (row, col). We'll index 1-10.

Row3: X at (3,2),(3,3),(3,4). Also X at (3,8).
Row4: X at (4,8).
Row6: X at (6,4),(6,5).
Row7: X at (7,4).
Row8: X at (8,8).
Row9: X at (9,2),(9,3),(9,7),(9,8),(9,9).
Row10: X at (10,2),(10,3).

Now we need to identify clusters: adjacency likely 4-neighbor (up/down/left/right). Let's find clusters.

Cluster A: The group at (3,2),(3,3),(3,4) maybe connected to (6,4),(6,5),(7,4)? Let's check connectivity: (3,4) is at row3 col4. (4,4) is '.'; (5,4) '.'; (6,4) X. So there is a vertical gap of 2 rows. So not connected. So cluster A is just the three X's at row3 col2-4. That's size 3.

Cluster B: The group at (3,8),(4,8),(8,8). Wait (4,8) is adjacent to (3,8). (5,8) '.'; (6,8) '.'; (7,8) '.'; (8,8) X. So (3,8) and (4,8) are connected; (8,8) is separate. So cluster B: (3,8),(4,8) size 2.

Cluster C: The group at (6,4),(6,5),(7,4). Let's check connectivity: (6,4) adjacent to (6,5) horizontally; (6,4) adjacent to (7,4) vertically. So cluster size 3.

Cluster D: The group at (9,2),(9,3),(10,2),(10,3). These four X's form a 2x2 block. So cluster size 4.

Cluster E: The group at (9,7),(9,8),(9,9). These three X's adjacent horizontally. So cluster size 3.

Cluster F: The group at (9,7),(9,8),(9,9) we counted. Wait we also have (9,7),(9,8),(9,9). That's cluster E. Are there any other X's? Let's check: (9,7),(9,8),(9,9). That's cluster E. Are there any X's at (9,7) etc. Already counted. So cluster E size 3.

Also cluster at (9,7),(9,8),(9,9) is separate from cluster at (9,2),(9,3),(10,2),(10,3). Yes.

Also cluster at (9,7),(9,8),(9,9) maybe also adjacent to (8,8)? Wait (8,8) is X but not adjacent to (9,7) or (9,8) or (9,9) because adjacency is 4-neighbor. (8,8) is at row8 col8. (9,8) is at row9 col8. They are adjacent vertically: (8,8) and (9,8) are adjacent. So cluster B had (3,8),(4,8) and cluster E has (9,7),(9,8),(9,9). But (8,8) is X at row8 col8. That is adjacent to (9,8). So cluster E should include (8,8) as well. Wait we earlier considered cluster B as (3,8),(4,8). But (8,8) is separate. But (8,8) is adjacent to (9,8). So cluster E includes (8,8),(9,7),(9,8),(9,9). So cluster E size 4. Let's re-evaluate.

Let's list all X coordinates again:

Row3: (3,2),(3,3),(3,4),(3,8)
Row4: (4,8)
Row6: (6,4),(6,5)
Row7: (7,4)
Row8: (8,8)
Row9: (9,2),(9,3),(9,7),(9,8),(9,9)
Row10: (10,2),(10,3)

Now cluster connectivity:

- Cluster 1: (3,2),(3,3),(3,4) size 3.

- Cluster 2: (3,8),(4,8) size 2.

- Cluster 3: (6,4),(6,5),(7,4) size 3.

- Cluster 4: (9,2),(9,3),(10,2),(10,3) size 4.

- Cluster 5: (8,8),(9,7),(9,8),(9,9) size 4.

Check if any other connections: (8,8) adjacent to (9,8). Yes. So cluster 5 includes (8,8),(9,7),(9,8),(9,9). That's size 4.

Now we have cluster sizes: 3,2,3,4,4.

Now output grid for Example 1:

Output grid:

Row1: . . . . . . . . . .
Row2: . . . . . . . . . .
Row3: . R R R . . . G . .
Row4: . . . . . . . G . .

Row6: . . . R R . . . . .
Row7: . . . R . . . . . .
Row8: . . . . . . . B . .
Row9: . B B . . . B B B .
Row10: . B B . . . . . . .

Let's map colors to cluster sizes.

We need to see which cluster corresponds to which color.

Cluster 1 (size 3) at (3,2),(3,3),(3,4) -> output row3 col2-4 are R R R. So size 3 cluster -> R.

Cluster 2 (size 2) at (3,8),(4,8) -> output row3 col8 is G, row4 col8 is G. So size 2 cluster -> G.

Cluster 3 (size 3) at (6,4),(6,5),(7,4) -> output row6 col4-5 are R R, row7 col4 is R. So size 3 cluster -> R again.

Cluster 4 (size 4) at (9,2),(9,3),(10,2),(10,3) -> output row9 col2-3 are B B, row10 col2-3 are B B. So size 4 cluster -> B.

Cluster 5 (size 4) at (8,8),(9,7),(9,8),(9,9) -> output row8 col8 is B, row9 col7-9 are B B B. So size 4 cluster -> B.

We need to solve a grid transformation puzzle. We have a metaphorical description: "Dark open water with clusters of grey vessels rafted together at scattered anchorages. Count the boats in each raft-up and repaint them in the harbor signal color for that raft size." So we have a grid with '.' representing black (dark water). 'X' representing grey vessels (boats). We need to count the boats in each raft-up (connected group of X's). Then repaint them in the harbor signal color for that raft size. The output shows colors: R, G, B, etc. We need to map group size to color. Let's analyze training example 1.

Input grid 10x10. Output grid 10x10. Let's parse.

Input Example 1:

We need to map each group of X's to a color. Let's identify groups in input.

Group 1: Row3 columns 2-4: X X X contiguous horizontally. Also check adjacency: Are there any other X's adjacent? Row4 col8 is separate. So group 1 size = 3. Output: those positions become R R R. So size 3 -> R.

Group 2: Row3 col8: X. Row4 col8: X. Row5 none. Row6 none. So vertical pair of X's at (3,8) and (4,8). That's size 2. Output: those positions become G G. So size 2 -> G.

Group 3: Row6 col4-5: X X. Row7 col4: X. So group of 3? Let's check connectivity: Row6 col4 adjacent to Row6 col5 horizontally. Row7 col4 adjacent vertically to Row6 col4. So group size 3. Output: those positions become R R R. Yes.

Group 4: Row8 col8: X. Row9 col8-10: X X X. Row10 col2-3: X X. Wait check connectivity: Row8 col8 adjacent to Row9 col8 vertically. Row9 col8 adjacent to Row9 col9 horizontally, and to Row9 col10 horizontally. Row9 col8 also adjacent to Row10 col8? Row10 col8 is '.' so no. Row9 col8 also adjacent to Row10 col8? no. Row9 col8 adjacent to Row10 col8? no. Row9 col8 adjacent to Row10 col8? no. Row9 col8 adjacent to Row10 col8? no. Row9 col8 adjacent to Row10 col8? no. Row9 col8 adjacent to Row10 col8? no. So group 4 includes Row8 col8, Row9 col8-10. That's 4 cells. Output: those positions become B B B B? Let's check output: Row8 col8: B. Row9 col8-10: B B B. Yes. So size 4 -> B.

Group 5: Row9 col2-3: X X. Row10 col2-3: X X. That's a 2x2 block of 4 cells. Are they connected? Yes. So group size 4. Output: those positions become B B B B. Row9 col2-3: B B. Row10 col2-3: B B. Yes.

So mapping: size 3 -> R, size 2 -> G, size 4 -> B. What about size 1? Not present. But we might need to map size 1 to some color maybe Y? Let's examine color key: . = black, B=blue, R=red, G=green, Y=yellow, X=grey, M=magenta, O=orange, A=azure, W=maroon. The colors used in output: R, G, B. So maybe mapping: 1->Y, 2->G, 3->R, 4->B, 5->M, 6->O, 7->A, 8->W? But we need to confirm.

Let's analyze the metaphor: "harbor signal color for that raft size." In maritime, there are standard signal colors for group sizes? Not sure. But maybe the mapping is: 1=Y (yellow), 2=G (green), 3=R (red), 4=B (blue), 5=M (magenta), 6=O (orange), 7=A (azure), 8=W (maroon). That seems plausible: each color corresponds to a number. But we need to confirm with training examples. Only sizes 2,3,4 appear. So mapping fits.

But we need to confirm that the mapping is indeed 1->Y, 2->G, 3->R, 4->B, 5->M, 6->O, 7->A, 8->W. Let's check if any other training examples exist. Only one training example given. So we can't confirm further. But we can deduce that the mapping is likely sequential: 1=Y, 2=G, 3=R, 4=B, 5=M, 6=O, 7=A, 8=W. This is a typical mapping used in some ARC tasks: mapping group size to color. The color key order: Y, G, R, B, M, O, A, W. That matches the order of colors in the key: Y=yellow, G=green, R=red, B=blue, M=magenta, O=orange, A=azure, W=maroon. So the mapping is likely 1->Y, 2->G, 3->R, 4->B, 5->M, 6->O, 7->A, 8->W. This is a common pattern: mapping group size to color in ascending order of colors.

Thus the transformation rule: For each connected component of X's (boats), count the number of X's. Then recolor all cells in that component with the color corresponding to that size: 1->Y, 2->G, 3->R, 4->B, 5->M, 6->O, 7->A, 8->W. The background '.' remains '.'.

Now we need to apply to test input.

Test Input grid 10x10:

We need to solve a grid transformation puzzle. We have a metaphorical description: "dark divination cloth with clusters of pale bone fragments of varying group sizes. Count the touching shards in each cluster to determine which deity claims the omen, then let that patron's sacred color suffuse the bones." So we have a grid with '.' representing black (empty cloth). 'X' representing grey bone fragments. The transformation: For each cluster of X's (connected orthogonally? maybe 4-neighbor connectivity), we count the number of touching shards in each cluster. That is, the size of the cluster (# of X cells). Then we determine which deity claims the omen. The output shows colored cells: R, G, B, etc. The mapping from cluster size to color is likely predetermined. We need to deduce mapping from training example.

We have Example 1 input and output. Let's analyze.

Example 1 Input grid 10x10. Let's parse.

Input grid lines:

1: . . . . . . . . . .
2: . . . . . . . . . .
3: . X X X . . . X . .
4: . . . . . . . X . .
5: . . . . . . . . . .
6: . . . X X . . . . .
7: . . . X . . . . . .
8: . . . . . . . X . .
9: . X X . . . X X X .
10: . X X . . . . . . .

Let's mark coordinates (row, col). We'll identify clusters of X's.

We need to determine connectivity: likely 4-neighbor (up, down, left, right). Let's examine.

Row3: positions (3,2),(3,3),(3,4) are X. Row3 col8 is X. Row4 col8 is X. Row6 col4, col5 are X. Row7 col4 is X. Row8 col8 is X. Row9 col2, col3 are X. Row9 col7, col8, col9 are X. Row10 col2, col3 are X.

Also row3 col8 and row4 col8 are adjacent vertically, so cluster. Row8 col8 is separate? Wait row8 col8 is X, but row7 col8? Row7 col8 is '.'; row9 col8 is X. So row8 col8 is adjacent to row9 col8? Yes, row8 col8 is above row9 col8, so they are connected. So cluster includes row3 col8, row4 col8, row8 col8, row9 col7,8,9? Wait row9 col7,8,9 are X. Row8 col8 is adjacent to row9 col8. Row9 col7 adjacent to row9 col8. Row9 col9 adjacent to row9 col8. So cluster includes all those. Also row3 col8 and row4 col8 are connected to row8 col8? They are separated by rows 5 and 6 and 7. Are there any X's in between? Row5 col8 is '.'; row6 col8 '.'; row7 col8 '.'; row8 col8 X. So no connectivity. So cluster of X's at col8 row3 and row4 is separate from cluster at row8 col8 and row9 col7-9. So we have at least two clusters in that vertical column.

Also cluster at row3 col2-4: positions (3,2),(3,3),(3,4). Are there any adjacent X's below? Row4 col2-4 are '.'; row2 col2-4 '.'; row3 col2-4 are only cluster. So cluster size 3.

Cluster at row6 col4-5: (6,4),(6,5). Row7 col4 is X adjacent to (6,4). So cluster includes (6,4),(6,5),(7,4). Are there any other X's adjacent? Row5 col4-5 '.'; row8 col4-5 '.'; row6 col4-5 adjacent to each other. So cluster size 3.

Cluster at row9 col2-3 and row10 col2-3: (9,2),(9,3),(10,2),(10,3). Are they connected? Yes, (9,2) adjacent to (10,2); (9,3) adjacent to (10,3); (9,2) adjacent to (9,3). So cluster size 4.

Cluster at row8 col8, row9 col7-9: (8,8),(9,7),(9,8),(9,9). Are there any other X's adjacent? Row7 col8 '.'; row10 col8 '.'; row8 col7 '.'; row8 col9 '.'; row9 col6 '.'; row9 col10 '.'; row10 col7 '.'; row10 col8 '.'; row10 col9 '.'; So cluster size 4.

Also cluster at row3 col8 and row4 col8: (3,8),(4,8). Are they adjacent? Yes, vertical adjacency. So cluster size 2.

Wait we also have cluster at row3 col8? Actually we counted cluster of (3,8),(4,8) size 2. But we also counted cluster at row8 col8 etc. So we have clusters: size 3 (top left), size 2 (col8 top), size 3 (middle cluster), size 4 (bottom left), size 4 (bottom right cluster). Let's double-check if any other X's: row3 col8, row4 col8, row8 col8, row9 col7-9, row9 col2-3, row10 col2-3, row6 col4-5, row7 col4, row3 col2-4. That's all.

Now output grid:

Output lines:

1: . . . . . . . . . .
2: . . . . . . . . . .
3: . R R R . . . G . .
4: . . . . . . . G . .
5: . . . . . . . . . .
6: . . . R R . . . . .
7: . . . R . . . . . .
8: . . . . . . . B . .
9: . B B . . . B B B .
10: . B B . . . . . . .

Let's map output colors to clusters.

Row3 col2-4: output R R R. So cluster size 3 -> color R (red). Good.

Row3 col8, row4 col8: output G at (3,8) and G at (4,8). So cluster size 2 -> color G (green). Good.

Row6 col4-5, row7 col4: output R R at (6,4),(6,5) and R at (7,4). So cluster size 3 -> color R again. Good.

Row9 col2-3, row10 col2-3: output B B at (9,2),(9,3) and B B at (10,2),(10,3). So cluster size 4 -> color B (blue). Good.

Row8 col8, row9 col7-9: output B at (8,8), B at (9,7),(9,8),(9,9). So cluster size 4 -> color B again. Good.

Thus mapping: cluster size 2 -> G, cluster size 3 -> R, cluster size 4 -> B. What about cluster size 1? Not present. But we might need mapping for other sizes. The color key includes Y, M, O, A, W. Maybe cluster sizes 5,6,7,8,9? But we only have up to 4. But maybe there are other clusters in test input.

We need to deduce mapping from cluster size to color. The mapping

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A dark stage floor with clusters of dancers (grey) holding various small formations. What to do: Count the dancers in each formation and assign them the costume color designated for that formation size. Grid details: Same stage. Empty floor stays dark. Each dancer group appears in their formation-size costume color."

We have training example 1: Input grid 10x10 with '.' and 'X' (grey). Output grid 10x10 with '.' and colors R, G, B. The rule: Count the dancers in each formation and assign them the costume color designated for that formation size. So we need to identify clusters of X's (connected components). For each cluster, count the number of X's. Then assign a color based on cluster size. The mapping from size to color: we need to deduce from example.

Let's analyze example 1.

Input grid:

Row indices 0-9, columns 0-9.

I'll rewrite input grid with coordinates.

Input:

Row0: . . . . . . . . . .

Let's mark X positions:

Row3: col7
Row5: col3,4
Row6: col3
Row7: col7
Row8: col1,2; col6,7,8
Row9: col1,2

We need to find connected components. Connectivity likely 4-directional (up, down, left, right). Let's analyze.

Component A: cluster around (2,1),(2,2),(2,3). Are they connected to others? (2,1) adjacent to (3,1) none; (2,2) adjacent to (2,1),(2,3),(1,2),(3,2). None of those are X except (2,1),(2,3). So cluster of size 3 at top left. Output shows R R R at row2 col1-3. Yes output row2: . R R R . . . G . . Wait output row2: ". R R R . . . G . ." Actually output row2: ". R R R . . . G . ." Let's check. Output row2: ". R R R . . . G . ." So cluster of size 3 turned to R. So size 3 -> R.

Component B: cluster at (2,7),(3,7),(7,7),(8,6),(8,7),(8,8). Wait check connectivity: (2,7) adjacent to (3,7). (3,7) adjacent to (2,7),(4,7),(3,6),(3,8). None of those are X except (2,7). So cluster of size 2? Wait (2,7) and (3,7) only. But there are also X at (7,7) and (8,6),(8,7),(8,8). Are they connected? Let's check connectivity: (7,7) adjacent to (6,7),(8,7),(7,6),(7,8). (6,7) none; (8,7) is X; (7,6) none; (7,8) none. So (7,7) connected to (8,7). (8,7) adjacent to (8,6),(8,8),(7,7),(9,7). So (8,6) and (8,8) are X. So cluster of size 4? Wait we have X at (2,7),(3,7),(7,7),(8,6),(8,7),(8,8). Are (3,7) connected to (7,7)? No, because there is a gap of rows 4-6. So they are separate clusters. So cluster B1: (2,7),(3,7) size 2. Output row2 col7: G? Wait output row2 col7: G. Output row3 col7: G. So size 2 -> G.

Cluster B2: (7,7),(8,6),(8,7),(8,8). That's 4 X's. Output row7 col7: B? Wait output row7 col7: B? Let's check output row7: ". . . . . . . X . ." Actually output row7: ". . . . . . . X . ." Wait output row7: ". . . . . . . X . ." Wait we need to check output grid. Let's rewrite output grid from example:

Output:
. . . . . . . . . .
. . . . . . . . . .
. R R R . . . G . .
. . . . . . . G . .
. . . . . . . . . .
. . . R R . . . . .
. . . R . . . . . .
. . . . . . . B . .
. B B . . . B B B .
. B B . . . . . . .

Let's parse output row by row:

Row0: all .
Row1: all .
Row2: . R R R . . . G . .
Row3: . . . . . . . G . .
Row4: all .
Row5: . . . R R . . . . .
Row6: . . . R . . . . . .
Row7: . . . . . . . B . .
Row8: . B B . . . B B B .
Row9: . B B . . . . . . .

So cluster B2: positions (7,7) -> B. (8,6),(8,7),(8,8) -> B. So cluster size 4 -> B.

Cluster C: (5,3),(5,4),(6,3). That's 3 X's. Output row5 col3,4: R R. Row6 col3: R. So size 3 -> R again.

Cluster D: (8,1),(8,2),(9,1),(9,2). That's 4 X's. Output row8 col1,2: B B. Row9 col1,2: B B. So size 4 -> B again.

So mapping: size 2 -> G, size 3 -> R, size 4 -> B. Are there any other sizes? Not in example. But we might need to handle other sizes in test input. The mapping might be: 2 -> G, 3 -> R, 4 -> B. But we need to confirm if there are other sizes like 1, 5, etc. The puzzle might have only these sizes. But we need to deduce mapping from training examples. There is only one training example. But maybe there are other training examples not shown? The problem statement only shows Example 1. So we only have mapping for sizes 2,3,4. But test input may contain clusters of other sizes. We need to guess mapping for other sizes. But maybe the puzzle only uses these sizes. Let's examine test input.

Test Input grid:

Row0: . . . . . . . . . X
Row1: . . . . . . . . . X
Row2: . . X X . X X . . X
Row3: . X X . . . X . . X
Row4: . . . . . . . . . .
Row5: . . . . . . . . . .
Row6: X . . . . . . . . .
Row7: X . . X X . . X . .
Row8: X . . . . . . X . .
Row9: . . . . . . . . . .

Let's mark X positions:

Row0 col9
Row1 col9
Row2 col2,3,5,6,9
Row3 col1,2,6,9
Row4 none
Row5 none
Row6 col0
Row7 col0,3,4,7

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A cutting board (black surface) scattered with clusters of raw mushrooms (grey) of varying bunch sizes. What to do: Weigh each connected bunch by counting its pieces, then coat it in the sauce assigned to that weight class. Grid details: Same board layout. Background unchanged. Each mushroom cluster takes on the color of its assigned marinara."

We have training example 1: Input grid 10x10 with '.' and 'X' cells. Output grid 10x10 with '.' and colors R, G, B. The transformation: For each connected component of X's (connected orthogonally? likely 4-neighbor connectivity), count the number of cells. Then assign a color based on weight class. The mapping from size to color: In example 1, we need to deduce mapping.

Let's analyze example 1.

Input grid:

Row indices 0-9, columns 0-9.

I'll rewrite input grid with coordinates.

Input:

Row0: . . . . . . . . . .
Row1: . . . . . . . . . .
Row2: . X X X . . . X . .
Row3: . . . . . . . X . .
Row4: . . . . . . . . . .
Row5: . . . X X . . . . .
Row6: . . . X . . . . . .
Row7: . . . . . . . X . .
Row8: . X X . . . X X X .
Row9: . X X . . . . . . .

Let's mark X positions.

Row2: col1,2,3 are X. Also col7 is X.
Row3: col7 is X.
Row5: col3,4 are X.
Row6: col3 is X.
Row7: col7 is X.
Row8: col1,2 are X. col6,7,8 are X.
Row9: col1,2 are X.

So we have several clusters.

Let's identify connected components (4-neighbor adjacency). We'll list each cluster.

Cluster A: The group at top-left: Row2 col1-3. Are they connected to any other X? Let's check adjacency: Row2 col1 adjacent to row1 col1 (.), row3 col1 (.), row2 col0 (.), row2 col2 (X). So cluster includes col1,2,3. Row2 col3 adjacent to row1 col3 (.), row3 col3 (.), row2 col2 (X). So cluster A size 3.

Cluster B: The group at top-right: Row2 col7, Row3 col7, Row7 col7, Row8 col6-8? Wait check connectivity: Row2 col7 adjacent to Row3 col7 (down). Row3 col7 adjacent to Row2 col7 (up) and Row4 col7 (.), Row3 col6 (.), Row3 col8 (.). So cluster includes Row2 col7 and Row3 col7. Row7 col7 is far away: row4-6 col7 are '.'; row7 col7 is isolated? But maybe connected via row8 col7? Let's check: Row7 col7 adjacent to Row6 col7 (.), Row8 col7 (X). Row8 col7 adjacent to Row7 col7 (up), Row9 col7 (.), Row8 col6 (X), Row8 col8 (X). So cluster includes Row7 col7, Row8 col6,7,8. Row8 col6 adjacent to Row7 col6 (.), Row9 col6 (.), Row8 col5 (.), Row8 col7 (X). So cluster includes Row8 col6,7,8. Row9 col6? no. So cluster B includes Row2 col7, Row3 col7, Row7 col7, Row8 col6,7,8. Are they connected? Let's check connectivity: Row2 col7 to Row3 col7 is connected. Row3 col7 to Row4 col7 (.) no. Row3 col7 to Row2 col7 (connected). Row3 col7 to Row3 col6 (.) no. Row3 col7 to Row3 col8 (.) no. So cluster B currently includes Row2 col7 and Row3 col7. Row7 col7 is not connected to them because there is a gap of rows 4-6. So cluster B splits into two separate clusters: cluster B1: Row2 col7, Row3 col7. cluster B2: Row7 col7, Row8 col6,7,8. But we need to check if Row7 col7 is connected to Row8 col7 (X). Yes. So cluster B2 includes Row7 col7, Row8 col6,7,8. Are there any other X's adjacent? Row8 col6 adjacent to Row8 col7 (X). Row8 col8 adjacent to Row8 col7 (X). Row8 col6 adjacent to Row7 col6 (.), Row9 col6 (.), Row8 col5 (.). So cluster B2 size 4? Wait count: Row7 col7 (1), Row8 col6 (2), Row8 col7 (3), Row8 col8 (4). So cluster B2 size 4.

Cluster C: The group at middle-left: Row5 col3,4 and Row6 col3. Are they connected? Row5 col3 adjacent to Row5 col4 (X), Row6 col3 (X). Row5 col4 adjacent to Row5 col3 (X), Row6 col4 (.), Row4 col4 (.), Row5 col5 (.). Row6 col3 adjacent to Row5 col3 (X), Row7 col3 (.), Row6 col2 (.), Row6 col4 (.). So cluster C includes Row5 col3,4, Row6 col3. Size 3.

Cluster D: The group at bottom-left: Row8 col1,2 and Row9 col1,2. Are they connected? Row8 col1 adjacent to Row8 col2 (X), Row9 col1 (X). Row8 col2 adjacent to Row8 col1 (X), Row9 col2 (X). Row9 col1 adjacent to Row9 col2 (X). So cluster D includes Row8 col1,2, Row9 col1,2. Size 4.

Also there might be cluster E: Row8 col6,7,8 we already counted in cluster B2. So all clusters accounted.

Now output grid:

Output:

Row0: . . . . . . . . . .
Row1: . . . . . . . . . .
Row2: . R R R . . . G . .
Row3: . . . . . . . G . .
Row4: . . . . . . . . . .
Row5: . . . R R . . . . .
Row6: . . . R . . . . . .
Row7: . . . . . . . B . .
Row8: . B B . . . B B B .
Row9: . B B . . . . . . .

Let's map colors: R=red, G=green, B=blue.

Now we need to see mapping from cluster size to color.

Cluster A size 3 -> output color R at positions Row2 col1-3. Yes, cluster A is colored R.

Cluster B1 size 2? Wait cluster B1 includes Row2 col7, Row3 col7. That's size 2. Output at Row2 col7 is G, Row3 col7 is G. So cluster size 2 -> G.

Cluster B2 size 4 -> output color B at Row7 col7, Row8 col6-8. Yes, cluster size 4 -> B.

Cluster C size 3 -> output color R at Row5 col3,4 and Row6 col

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: An empty field (black) with clusters of unassigned players (grey) standing in small groups. What to do: Count the members of each group and issue them the jersey color designated for that squad size. Grid details: Same field. Empty grass stays black. Each group now wears their size-assigned jersey color."

We have training example 1: Input grid 10x10 with '.' and 'X' (grey). Output grid has '.' and colors: R, G, B. So transformation: For each cluster of X's (connected components), count the number of cells in the cluster. Then assign a color based on cluster size. The mapping from size to color: We need to deduce from example.

Let's analyze Example 1.

Input grid:

Row1: . . . . . . . . . .
Row2: . . . . . . . . . .
Row3: . X X X . . . X . .
Row4: . . . . . . . X . .
Row5: . . . . . . . . . .
Row6: . . . X X . . . . .
Row7: . . . X . . . . . .
Row8: . . . . . . . X . .
Row9: . X X . . . X X X .
Row10: . X X . . . . . . .

Let's mark coordinates (row, col). We'll identify clusters of X's. Connectivity: likely 4-directional (up, down, left, right). Let's examine.

Cluster 1: Row3 col2-4: X X X contiguous horizontally. Also Row4 col8: X? Wait row4 col8 is X but not connected to row3 col2-4. Let's examine each cluster.

Let's list all X positions:

Row3: col2, col3, col4, col8
Row4: col8
Row6: col4, col5
Row7: col4
Row8: col8
Row9: col2, col3, col7, col8, col9
Row10: col2, col3

Now cluster connectivity:

Cluster A: Row3 col2-4 (3 cells). Are there any adjacent X's? Row4 col2? No. Row3 col2 adjacent to row2 col2? No. Row3 col4 adjacent to row4 col4? No. So cluster A size 3.

Cluster B: Row3 col8 and Row4 col8 and Row8 col8? Wait Row4 col8 adjacent to Row3 col8 (vertical). Row8 col8 is far away (row8). Row4 col8 adjacent to Row5 col8? Row5 col8 is '.'; Row4 col8 adjacent to Row3 col8 (connected). Row4 col8 adjacent to Row5 col8 '.'; Row4 col8 adjacent to Row4 col7 '.'; Row4 col8 adjacent to Row4 col9 '.'; Row4 col8 adjacent to Row3 col8 (connected). Row8 col8 is not adjacent to Row4 col8 (distance 4). So cluster B: Row3 col8 + Row4 col8 = 2 cells.

Cluster C: Row6 col4, col5, Row7 col4. Let's examine connectivity: Row6 col4 adjacent to Row6 col5 (horizontal). Row6 col4 adjacent to Row7 col4 (vertical). Row6 col5 adjacent to Row7 col5? Row7 col5 '.'; Row6 col5 adjacent to Row5 col5 '.'; Row6 col5 adjacent to Row6 col6 '.'; Row6 col5 adjacent to Row7 col5 '.'; So cluster C size 3 cells: (6,4), (6,5), (7,4).

Cluster D: Row9 col2, col3, Row10 col2, col3. Let's examine connectivity: Row9 col2 adjacent to Row9 col3 (horizontal). Row9 col2 adjacent to Row10 col2 (vertical). Row9 col3 adjacent to Row10 col3 (vertical). So cluster D size 4 cells: (9,2),(9,3),(10,2),(10,3).

Cluster E: Row9 col7, col8, col9. Are they connected? Row9 col7 adjacent to Row9 col8 (horizontal). Row9 col8 adjacent to Row9 col9 (horizontal). Row9 col7 adjacent to Row8 col7 '.'; Row9 col8 adjacent to Row8 col8 X? Wait Row8 col8 is X but not part of cluster E because cluster E is row9 col7-9. But row8 col8 is X but not adjacent to row9 col8? Actually row8 col8 is above row9 col8, so they are adjacent vertically. So row8 col8 is adjacent to row9 col8. So cluster E includes row8 col8 as well. Let's check connectivity: Row8 col8 adjacent to Row9 col8. So cluster E includes row8 col8. Also row8 col8 adjacent to row7 col8 '.'; row8 col8 adjacent to row8 col7 '.'; row8 col8 adjacent to row8 col9 '.'; row8 col8 adjacent to row9 col8 (connected). So cluster E size 4 cells: (8,8),(9,7),(9,8),(9,9). Wait also row3 col8 and row4 col8 are separate cluster B. So cluster E is separate.

Now we have cluster sizes: 3, 2, 3, 4, 4.

Now output grid:

Let's examine output grid:

Row1: . . . . . . . . . .
Row2: . . . . . . . . . .
Row3: . R R R . . . G . .
Row4: . . . . . . . G . .
Row5: . . . . . . . . . .
Row6: . . . R R . . . . .
Row7: . . . R . . . . . .
Row8: . . . . . . . B . .
Row9: . B B . . . B B B .
Row10: . B B . . . . . . .

Let's map colors to clusters:

Cluster A (size 3) at row3 col2-4: output shows R R R. So size 3 -> R.

Cluster B (size 2) at row3 col8, row4 col8: output shows G at row3 col8, G at row4 col8. So size 2 -> G.

Cluster C (size 3) at row6 col4, col5, row7 col4: output shows R at row6 col4, R at row6 col5, R at row7 col4. So size 3 -> R again.

Cluster D (size 4) at row9 col2-3, row10 col2-3: output shows B at row9 col2, B at row9 col3, B at row10 col2, B at row10 col3. So size 4 -> B.

Cluster E (size 4) at row8 col8, row9 col7-9: output shows B at row8 col8, B at row9 col7, B at row9 col8, B at row9 col9. So size 4 -> B.

Thus mapping: size 2 -> G, size 3 -> R, size 4 -> B. What about other sizes? Not present in example. But we might need to deduce mapping for other sizes. The puzzle may involve mapping cluster size to color. The color key includes many colors: B, R, G, Y, M, O, A, W. So maybe mapping: 1->Y? 2-&

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A dark radar screen with scattered grey storm cells of varying extent. What to do: Measure each connected weather system by its cell count, then paint it in the alert color assigned to that severity tier. Grid details: Same radar dimensions. Clear sky stays dark. Each storm system is recolored by its size-based alert level."

We have training example 1: Input grid 10x10 with '.' and 'X' cells. Output grid has '.' and colored cells: R, G, B. So we need to map each connected component of X's to a color based on its size. The mapping: small components -> B? Or maybe B for small, G for medium, R for large? Let's analyze.

We need to parse the training example. Let's reconstruct the input grid coordinates. We'll index rows 0-9, columns 0-9.

Input Example 1:

Row0: . . . . . . . . . .
Row1: . . . . . . . . . .
Row2: . X X X . . . X . .
Row3: . . . . . . . X . .
Row4: . . . . . . . . . .
Row5: . . . X X . . . . .
Row6: . . . X . . . . . .
Row7: . . . . . . . X . .
Row8: . X X . . . X X X .
Row9: . X X . . . . . . .

Let's mark X positions:

Row2: col1,2,3; col7
Row3: col7
Row5: col3,4
Row6: col3
Row7: col7
Row8: col1,2; col6,7,8
Row9: col1,2

So we have several connected components. Let's identify them.

Component A: The cluster at top-left: row2 col1-3. Are they connected to any other X? Let's check adjacency: 4-neighbor connectivity (likely). Row2 col1-3 are adjacent horizontally. Are they connected to any other X? Row3 col? Row3 col7 is far. Row5 col3? Row5 col3 is two rows below row3 col3? Wait row3 col3 is '.'; row4 col3 '.'; row5 col3 X. So not connected. So component A is just the 3 X's at row2 col1-3. Size = 3.

Component B: The vertical line at col7: row2 col7, row3 col7, row7 col7. Are they connected? Row2 col7 adjacent to row3 col7 (vertical). Row3 col7 adjacent to row4 col7 '.'; row5 col7 '.'; row6 col7 '.'; row7 col7 X. So row3 col7 not adjacent to row7 col7 because there is a gap of 3 rows. So they are separate components: row2-3 col7 is a component of size 2. Row7 col7 is a single X component of size 1.

Component C: The cluster at row5-6 col3-4: row5 col3,4; row6 col3. Are they connected? Yes: row5 col3 adjacent to row5 col4; row5 col3 adjacent to row6 col3. So component size = 3.

Component D: The cluster at bottom-left: row8 col1,2; row9 col1,2. Are they connected? Yes: row8 col1 adjacent to row8 col2; row8 col1 adjacent to row9 col1; row8 col2 adjacent to row9 col2. So component size = 4.

Component E: The cluster at row8 col6,7,8: row8 col6,7,8. Are they connected? Yes horizontally. So component size = 3.

So we have component sizes: 3, 2, 1, 3, 4, 3. Wait we also have maybe other components? Let's double-check: Did we miss any X? Row2 col7, row3 col7, row7 col7. Row5 col3,4; row6 col3. Row8 col1,2; row9 col1,2. Row8 col6,7,8. That's all.

Now output grid:

Row0: . . . . . . . . . .
Row1: . . . . . . . . . .
Row2: . R R R . . . G . .
Row3: . . . . . . . G . .
Row4: . . . . . . . . . .
Row5: . . . R R . . . . .
Row6: . . . R . . . . . .
Row7: . . . . . . . B . .
Row8: . B B . . . B B B .
Row9: . B B . . . . . . .

Let's map each component to color:

Component A (size 3) at row2 col1-3: output shows R R R. So size 3 -> R (red). Good.

Component B1 (size 2) at row2-3 col7: output shows G at row2 col7 and G at row3 col7. So size 2 -> G (green). Good.

Component B2 (size 1) at row7 col7: output shows B at row7 col7. So size 1 -> B (blue). Good.

Component C (size 3) at row5-6 col3-4: output shows R R at row5 col3-4; R at row6 col3. So size 3 -> R. Good.

Component D (size 4) at row8-9 col1-2: output shows B B at row8 col1-2; B B at row9 col1-2. So size 4 -> B. Wait but earlier we had size 1 -> B. So B is used for both size 1 and size 4? That seems inconsistent. Let's double-check: maybe we mis-identified component D. Wait row8 col1-2 and row9 col1-2: that's 4 cells. Output shows B B at row8 col1-2; B B at row9 col1-2. So yes, B for size 4. But earlier we had size 1 -> B. So B used for both 1 and 4? That can't be. Let's double-check the output for row7 col7: It shows B at row7 col7. Yes. So B used for size 1 and size 4. That seems contradictory. Maybe we mis-read the output: Let's re-check the output grid lines:

Output:
. . . . . . . . . .
. . . . . . . . . .
. R R R . . . G . .
. . . . . . . G . .
. . . . . . . . . .
. . . R R . . . . .
. . . R . . . . . .
. . . . . . . B . .
. B B . . . B B B .
. B B . . . . . . .

Yes, row7 col7 is B. So B used for size 1 and size 4. That seems odd. Let's double-check component D: maybe it's not size 4 but size 2? Wait row8 col1-2 and row9 col1-2: that's 4 cells. But maybe the connectivity is not 4-neighbor but 8-neighbor? But that wouldn't change size. Let's check if row8 col1-2 and row9 col1-2 are connected diagonally? They are adjacent vertically/horizontally. So size 4.

But maybe the rule is not based on component size but on something e

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A blank city grid (black) with grey building footprints of varying sizes scattered across it. What to do: Count the lots each footprint covers, then color-code it according to the zoning designation for that building class. Grid details: Same city grid. Empty lots remain black. Each footprint takes its zoning color."

We have training example 1: Input grid 10x10 with '.' and 'X' cells. Output grid 10x10 with '.' and colors: R, G, B. The mapping: The 'X' cells in input represent building footprints. In output, each contiguous region of X's is replaced by a color: R, G, B. The color depends on the size of the region? The description says: "Count the lots each footprint covers, then color-code it according to the zoning designation for that building class." So maybe the color depends on the number of cells in the region. Let's analyze training example 1.

Input grid:

Row1: . . . . . . . . . .
Row2: . . . . . . . . . .
Row3: . X X X . . . X . .
Row4: . . . . . . . X . .
Row5: . . . . . . . . . .
Row6: . . . X X . . . . .
Row7: . . . X . . . . . .
Row8: . . . . . . . X . .
Row9: . X X . . . X X X .
Row10: . X X . . . . . . .

Let's mark coordinates (row, col). We'll index 1-10.

Let's identify contiguous regions of X's (connected orthogonally? Usually 4-neighbor connectivity). Let's find each region.

Region A: Starting at (3,2). Let's trace: (3,2),(3,3),(3,4) contiguous horizontally. Also (4,8) is separate? Wait (3,8) is X. Let's list all X coordinates:

Row3: col2,3,4,8
Row4: col8
Row6: col4,5
Row7: col4
Row8: col8
Row9: col2,3,7,8,9
Row10: col2,3

Also row3 col8, row4 col8, row8 col8: these are vertical cluster? Let's check connectivity: (3,8) adjacent to (4,8) vertical. (4,8) adjacent to (8,8)? No, there is a gap: rows 5,6,7 between 4 and 8. So not connected. So (3,8) and (4,8) are a cluster of size 2. (8,8) is isolated? Wait (8,8) is X but adjacent to (9,8) which is X. So (8,8) and (9,8) are connected. Also (9,7) and (9,9) are X. So cluster at bottom right: (8,8),(9,7),(9,8),(9,9). Also (10,2),(10,3) are X. They are adjacent to (9,2),(9,3) which are X. So cluster at bottom left: (9,2),(9,3),(10,2),(10,3). Also (6,4),(6,5),(7,4) cluster: (6,4) adjacent to (6,5) and (7,4). So cluster of size 3. Also cluster at top left: (3,2),(3,3),(3,4) cluster of size 3. Also cluster at (3,8),(4,8) cluster of size 2. So we have clusters of sizes: 3,3,2,3,4? Wait bottom right cluster size 4? Let's count: (8,8),(9,7),(9,8),(9,9) = 4. So cluster sizes: 3,3,2,3,4,4? Wait bottom left cluster size 4? Let's count: (9,2),(9,3),(10,2),(10,3) = 4. So cluster sizes: 3,3,2,3,4,4. Actually we have 6 clusters: cluster1 size3 (top left), cluster2 size3 (middle left), cluster3 size2 (top right), cluster4 size3 (bottom left), cluster5 size4 (bottom right). Wait we counted 5 clusters? Let's recount: cluster1: (3,2),(3,3),(3,4) size3. cluster2: (6,4),(6,5),(7,4) size3. cluster3: (3,8),(4,8) size2. cluster4: (9,2),(9,3),(10,2),(10,3) size4. cluster5: (8,8),(9,7),(9,8),(9,9) size4. That's 5 clusters. Did we miss any? Let's check all X coordinates: row3 col2,3,4,8; row4 col8; row6 col4,5; row7 col4; row8 col8; row9 col2,3,7,8,9; row10 col2,3. That's 4+1+2+1+1+5+2 = 16 X cells. Let's sum cluster sizes: 3+3+2+4+4 = 16. Good. So 5 clusters.

Now output grid: Let's examine output to see mapping.

Output grid:

Row1: . . . . . . . . . .
Row2: . . . . . . . . . .
Row3: . R R R . . . G . .
Row4: . . . . . . . G . .
Row5: . . . . . . . . . .
Row6: . . . R R . . . . .
Row7: . . . R . . . . . .
Row8: . . . . . . . B . .
Row9: . B B . . . B B B .
Row10: . B B . . . . . . .

So mapping: cluster1 (top left) size3 -> color R. cluster2 (middle left) size3 -> color R. cluster3 (top right) size2 -> color G. cluster4 (bottom left) size4 -> color B. cluster5 (bottom right) size4 -> color B.

Thus mapping: size3 -> R, size2 -> G, size4 -> B. So color depends on cluster size. But we need to confirm if there are other sizes mapping to other colors. In training example, only sizes 2,3,4 appear. Colors used: R, G, B. So mapping: size2 -> G, size3 -> R, size4 -> B. That seems plausible.

But we need to confirm if there is any other rule: maybe color mapping is based on number of cells mod something? But we only have 3 colors. Let's examine the color key: . = black, B=blue, R=red, G=green, Y=yellow, X=grey, M=magenta, O=orange, A=azure, W=maroon. In training example, only B, R, G used. So mapping: maybe B=blue for size4, R=red for size3, G=green for size2. That matches typical color-coded zoning: maybe B=blue for large, R=red for medium, G=green for small. But we need to confirm with test input.

Test Input grid: 10x10 again. Let's list coordinates of X's.

Test Input:

Row1: . . . . . . . . . X
Row2: . . . . . . . . . X

Row4: . X X . . . X . . X

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A dark tactical map with grey markers indicating enemy positions, each cluster representing a unit of unknown strength. What to do: Assess each unit's strength by counting its connected positions, then replace the grey markers with the colored pin designated for that unit size. Grid details: Same map. Unmarked terrain stays dark. Each unit's markers are replaced with their strength-coded color."

We have training example 1: Input grid 10x10 with '.' and 'X' markers. Output grid has '.' and colored letters: R, G, B. The mapping: clusters of X's replaced by colors based on cluster size. Let's analyze.

Input Example 1:

Row1: . . . . . . . . . .
Row2: . . . . . . . . . .
Row3: . X X X . . . X . .
Row4: . . . . . . . X . .

Row7: . . . X . . . . . .
Row8: . . . . . . . X . .
Row9: . X X . . . X X X .
Row10: . X X . . . . . . .

Output Example 1:

Row1: . . . . . . . . . .
Row2: . . . . . . . . . .
Row3: . R R R . . . G . .

Row9: . B B . . . B B B .
Row10: . B B . . . . . . .

So we need to map cluster sizes to colors: R, G, B. Let's identify clusters.

We need to consider connectivity: likely 4-directional adjacency (up, down, left, right). Let's find clusters of X's.

Input grid coordinates: Let's index rows 1-10, columns 1-10.

Row3: positions (3,2),(3,3),(3,4) are X. Also (3,8) is X.

Row4: (4,8) is X.

Row6: (6,4),(6,5) are X.

Row7: (7,4) is X.

Row8: (8,8) is X.

Row9: (9,2),(9,3) are X; (9,7),(9,8),(9,9) are X.

Row10: (10,2),(10,3) are X.

Also row3 col8, row4 col8, row8 col8, row9 col7-9, etc.

Let's identify clusters:

Cluster A: The group at top left: (3,2),(3,3),(3,4). Are they connected? Yes horizontally. Are there any other X's adjacent? (4,2) is '.'; (2,2) '.'; (3,1) '.'; (3,5) '.'; So cluster size 3.

Cluster B: The group at (3,8),(4,8),(8,8),(9,7),(9,8),(9,9),(8,8) etc. Wait we need to check connectivity. Let's list all X's in that region:

(3,8)
(4,8)
(8,8)
(9,7),(9,8),(9,9)
(10,2),(10,3) are separate.

But (8,8) is far from (4,8). Are they connected via vertical adjacency? Let's check: (4,8) is at row4 col8. (5,8) is '.'; (6,8) '.'; (7,8) '.'; (8,8) is X. So there is a vertical gap of 3 rows. So they are not connected. So cluster B: (3,8),(4,8) maybe cluster size 2? Wait (3,8) adjacent to (4,8) vertically. So cluster size 2.

But output shows G at (3,8) and (4,8). Yes G at those positions. So cluster size 2 maps to G.

But we also have cluster at (8,8) alone? Let's check: (8,8) is X. Are there any adjacent X's? (7,8) '.'; (9,8) X; (8,7) '.'; (8,9) '.'; So (8,8) adjacent to (9,8). So cluster includes (8,8),(9,8). Also (9,7),(9,9) are adjacent to (9,8). So cluster includes (9,7),(9,8),(9,9). So cluster size 4? Let's count: (8,8),(9,7),(9,8),(9,9). That's 4 cells. Are there any other X's adjacent? (10,8) '.'; (10,7) '.'; (10,9) '.'; (8,7) '.'; (8,9) '.'; (7,8) '.'; So cluster size 4.

Output shows B at (8,8),(9,7),(9,8),(9,9). Yes B at those positions. So cluster size 4 maps to B.

Now cluster at (6,4),(6,5),(7,4). Let's check connectivity: (6,4) adjacent to (6,5) horizontally; (6,4) adjacent to (7,4) vertically. So cluster size 3. Output shows R at (6,4),(6,5),(7,4). Yes R.

Now cluster at (10,2),(10,3),(9,2),(9,3). Let's check connectivity: (9,2) adjacent to (9,3) horizontally; (9,2) adjacent to (10,2) vertically; (9,3) adjacent to (10,3) vertically. So cluster size 4. Output shows B at (9,2),(9,3),(10,2),(10,3). Yes B.

Also cluster at (3,2),(3,3),(3,4) size 3 -> R. Yes.

So mapping: cluster size 3 -> R; cluster size 2 -> G; cluster size 4 -> B. Are there any cluster size 1? None in example. But maybe there is mapping for size 1 -> something else? But we only have R, G, B. But maybe there are more colors for other sizes. Let's examine training example 2? Wait only one training example given. But we might need to deduce mapping for other sizes. But we only have 3 colors. But maybe there are only 3 possible cluster sizes in the puzzle: 2,3,4. But we need to consider test input: we need to identify cluster sizes and map to colors accordingly.

But we need to confirm mapping: cluster size 2 -> G; cluster size 3 -> R; cluster size 4 -> B. But we need to confirm that mapping is consistent with the metaphor: "Assess each unit's strength by counting its connected positions, then replace the grey markers with the colored pin designated for that unit size." So each cluster size corresponds to a color. The mapping might be predetermined: maybe 2=G, 3=R, 4=B. But we need to confirm if there is any other mapping like 1=Y or something. But we don't have example for size 1. But maybe there is no cluster of size 1 in training example. But test input might have cluster size 1. We need to guess mapping for size

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A dark garden bed with clusters of grey seedlings of varying group sizes poking through the soil. What to do: Count the sprouts in each cluster and tie the ribbon color that corresponds to that count around the group. Grid details: Same bed dimensions. Bare soil stays dark. Each seedling cluster displays its count-assigned ribbon color."

We have training example 1: Input grid with '.' and 'X' cells. Output grid with '.' and colored cells: R, G, B. The mapping: clusters of X's are counted, and each cluster gets a color based on the count. The color mapping: maybe 3 clusters of size 3 -> R? Let's analyze.

We need to deduce the rule: For each cluster of X's (connected components), count the number of X cells. Then assign a color based on the count. The mapping from count to color: maybe 1->? 2->? 3->? 4->? 5->? 6->? 7->? 8->? 9->? But we only see R, G, B in example. Let's analyze the example.

Example 1 Input grid: 10x10. Let's map coordinates. I'll index rows 0-9, columns 0-9.

Input:

Row0: . . . . . . . . . .
Row1: . . . . . . . . . .
Row2: . X X X . . . X . .
Row3: . . . . . . . X . .
Row4: . . . . . . . . . .
Row5: . . . X X . . . . .
Row6: . . . X . . . . . .
Row7: . . . . . . . X . .
Row8: . X X . . . X X X .
Row9: . X X . . . . . . .

Let's identify clusters of X's. Connectivity: likely orthogonal adjacency (4-neighbor). Let's find clusters.

Cluster A: Row2 col1-3: X X X contiguous horizontally. Also check adjacency to other X's: Row3 col7 is far. Row2 col7 is X. So cluster A is the group at (2,1),(2,2),(2,3). That's 3 cells.

Cluster B: Row2 col7: X. Row3 col7: X. Row7 col7: X. Row8 col6-8: X X X. Row9 col1-2: X X. Wait we need to check connectivity.

Let's list all X coordinates:

(2,1),(2,2),(2,3)
(2,7)
(3,7)
(5,3),(5,4)
(6,3)
(7,7)
(8,1),(8,2),(8,6),(8,7),(8,8)
(9,1),(9,2)

Now cluster connectivity:

- Cluster 1: (2,1),(2,2),(2,3) are connected horizontally. Are they connected to any other X? Check adjacency: (3,1) is ., (1,1) is ., (2,0) is ., (2,4) is . So cluster 1 is isolated. Size 3.

- Cluster 2: (2,7),(3,7),(7,7),(8,6),(8,7),(8,8). Are they connected? Let's see adjacency: (2,7) adjacent to (3,7). (3,7) adjacent to (2,7) and (4,7) is ., (3,6) is ., (3,8) is . So cluster includes (2,7),(3,7). (7,7) is far: row difference 4. Not connected. (8,6),(8,7),(8,8) are adjacent horizontally. Are they connected to (7,7)? (7,7) adjacent to (8,7). Yes, (7,7) adjacent to (8,7). So cluster includes (7,7),(8,6),(8,7),(8,8). Are they connected to (2,7),(3,7)? No. So cluster 2 is (2,7),(3,7). Size 2.

- Cluster 3: (5,3),(5,4),(6,3). These are connected: (5,3) adjacent to (5,4) and (6,3). (6,3) adjacent to (5,3). So cluster size 3.

- Cluster 4: (8,1),(8,2),(9,1),(9,2). These are connected: (8,1) adjacent to (8,2) and (9,1). (8,2) adjacent to (8,1),(9,2). (9,1) adjacent to (8,1),(9,2). (9,2) adjacent to (8,2),(9,1). So cluster size 4.

Thus we have clusters of sizes: 3, 2, 3, 4.

Now output grid:

Output:

Row0: . . . . . . . . . .
Row1: . . . . . . . . . .
Row2: . R R R . . . G . .
Row3: . . . . . . . G . .
Row4: . . . . . . . . . .
Row5: . . . R R . . . . .
Row6: . . . R . . . . . .
Row7: . . . . . . . B . .
Row8: . B B . . . B B B .
Row9: . B B . . . . . . .

Let's map output colors to clusters.

Cluster 1 (size 3) at (2,1),(2,2),(2,3) -> output R R R. So size 3 -> R.

Cluster 2 (size 2) at (2,7),(3,7) -> output G at (2,7) and G at (3,7). So size 2 -> G.

Cluster 3 (size 3) at (5,3),(5,4),(6,3) -> output R R R at (5,3),(5,4),(6,3). So size 3 -> R again.

Cluster 4 (size 4) at (8,1),(8,2),(9,1),(9,2) -> output B B B B at those positions. So size 4 -> B.

Thus mapping: size 2 -> G, size 3 -> R, size 4 -> B. We don't see other sizes. So mapping might be: 2->G, 3->R, 4->B. But we need to confirm if there is a mapping for other sizes. The color key includes many colors: B, R, G, Y, X, M, O, A, W. But only B, R, G used. Maybe mapping is: 1->Y, 2->G, 3->R, 4->B, 5->M, 6->O, 7->A, 8->W? But we need to deduce from the puzzle description: "Count the sprouts in each cluster and tie the ribbon color that corresponds to that count around the group." So each cluster gets a color based on its size. The mapping might be predetermined: maybe 1->Y, 2->G, 3->R, 4->B, 5->M, 6->O, 7->A, 8->W. But we need to confirm.

We have only one training example. But we can deduce mapping from the color key: The colors are B, R, G, Y, X, M, O, A, W. The key includes X=grey, but X is used as input symbol for grey seedlings. So X is not used as output color. The output uses B, R, G. So mapping might be: 2->G, 3->R, 4->B. But we need to confirm if 1->? maybe Y? But we don't have cluster of size 1. But we can guess.

We need to apply rule to test input. Let's analyze test input.

Test Input grid:

We need to solve a grid transformation puzzle. We have a metaphorical description, training examples, and test input. We need to deduce the transformation rule. Let's parse the problem carefully.

We have a 7x7 grid input. Output is a 3x3 grid. The description: "What you see: A crowded square buzzes with chatter. Most voices are faint — a whisper of maroon here, a murmur of orange there — but one color is practically shouting over everyone else, filling the room with its presence. The rest are just passersby. What to do: Listen to the crowd and find the voice that drowns out all others. That dominant voice doesn't just win the argument — it chooses a signature gesture, a pose struck in azure light on a small dark stage. Each color-voice has rehearsed its own distinctive pose: one stands bold as a horizon line, another rises like a bent elbow, another traces a zigzag path. The loudest voice steps onto the stage and strikes the only pose it knows. Grid details: The crowded square is always seven paces on each side. The stage where the winner performs is a tiny three-by-three platform, lit only in azure against darkness. No matter how chaotic the crowd, only one pose appears — chosen not by where anyone stood, but simply by who was loudest."

So we need to find the color that appears most frequently in the 7x7 grid. That color is the "loudest voice". Then we need to output a 3x3 grid that is the "pose" of that color. The pose is predetermined for each color. The description says: "Each color-voice has rehearsed its own distinctive pose: one stands bold as a horizon line, another rises like a bent elbow, another traces a zigzag path." So each color has a unique 3x3 pattern. The output grid is that pattern. The pattern is in azure (A) on a dark stage (black). So the output grid is 3x3 with azure cells (A) and black cells (.). The pattern is predetermined for each color. We need to deduce the mapping from color to pattern from the training examples.

We have two training examples. Let's analyze them.

Example 1 Input:

Row1: B . B . O . .
Row2: B B W B . B .
Row3: . . B B . R .
Row4: . . . . G . B
Row5: . Y . B . . B
Row6: . . B . R . A
Row7: . . B . O G B

Output:
. . A
A A .
. A .

So the output is a 3x3 grid:

Row1: . . A
Row2: A A .
Row3: . A .

We need to find the dominant color in the input. Let's count each color frequency.

Colors present: B, O, W, R, G, Y, A. Let's count.

I'll parse each row:

Row1: B . B . O . . => B:2, O:1
Row2: B B W B . B . => B:4, W:1
Row3: . . B B . R . => B:2, R:1
Row4: . . . . G . B => G:1, B:1
Row5: . Y . B . . B => Y:1, B:2
Row6: . . B . R . A => B:1, R:1, A:1
Row7: . . B . O G B => B:2, O:1, G:1

Now sum B: row1 2 + row2 4 + row3 2 + row4 1 + row5 2 + row6 1 + row7 2 = 14 B's. O: row1 1 + row7 1 = 2. W: 1. R: row3 1 + row6 1 = 2. G: row4 1 + row7 1 = 2. Y: 1. A: 1.

So B is the dominant color with 14 occurrences. So the output pattern corresponds to color B. The output pattern is:

. . A
A A .
. A .

So the pattern for B is that shape. Let's call it pattern_B.

Now Example 2 Input:

Row1: . G . G X G .
Row2: . . G G . . .
Row3: A . . . . . G
Row4: G Y G W G . G
Row5: . . W G B G G
Row6: . G G G . G .
Row7: . . . . . . G

Output:
. A A
. A .
. A .

So output pattern is:

Row1: . A A
Row2: . A .
Row3: . A .

We need to find the dominant color in this input. Let's count.

Colors: G, X, A, Y, W, B. Let's count each.

Row1: . G . G X G . => G:3, X:1
Row2: . . G G . . . => G:2
Row3: A . . . . . G => A:1, G:1
Row4: G Y G W G . G => G:4, Y:1, W:1
Row5: . . W G B G G => W:1, G:3, B:1
Row6: . G G G . G . => G:4
Row7: . . . . . . G => G:1

Now sum G: row1 3 + row2 2 + row3 1 + row4 4 + row5 3 + row6 4 + row7 1 = 18 G's. X:1. A:1. Y:1. W:2. B:1.

So G is dominant with 18 occurrences. So the output pattern corresponds to color G. The output pattern is:

. A A
. A .
. A .

So pattern_G is that shape.

Thus we have mapping:

Color B -> pattern_B = 
. . A
A A .
. A .

Color G -> pattern_G = 
. A A
. A .
. A .

We need to deduce the mapping for all colors. We have only two colors mapped. But we need to produce output for test input. The test input likely has a dominant color that we need to map to a pattern. We need to deduce the pattern for that color. But we only have patterns for B and G. We need to deduce the pattern for the dominant color in test input. The test input may have a color that is either B or G, or maybe another color. Let's check test input.

Test Input:

Row1: G . G . . . G
Row2: G . W X . . X
Row3: . G . G . R W
Row4: A G . G . . O
Row5: . G X . . G G
Row6: . . G G . . .
Row7: . . G . Y . .

We need to count each color.

Colors present: G, W, X, R, A, O, Y. Let's count.

Row1: G . G . . . G => G:3
Row2: G . W X . . X => G:1, W:1, X:2
Row3: . G . G . R W => G:2, R:1, W:1
Row4: A G . G . . O => A:1, G:2, O:1
Row5: . G X . . G G => G:3, X:1
Row6: . . G G . . . => G:2
Row7: . . G . Y . .

We need to solve a grid transformation puzzle. We have training examples with input 7x7 grids and output 3x3 grids. The description: "What you see: A crowded culture plate where several species of microorganism vie for resources. One species vastly outnumbers the rest, while rare mutant strains appear as isolated specimens. What to do: Identify which colony has achieved dominance through sheer population. Each dominant species, when it wins, expresses a unique molecular signature — a small, fixed fold pattern. Read off the winning species' signature. Grid details: The petri dish is a 7×7 field. The diagnostic result is always a 3×3 protein fold rendered in azure against a dark background."

So we need to find the dominant species (color) that has the largest population in the 7x7 grid. Then we need to output a 3x3 pattern of azure (A) that is the "signature" of that species. The pattern is fixed for each species? The output is always a 3x3 grid of azure (A) and black (.)? Wait, the output examples show azure (A) and black (.) only. Let's examine the training examples.

Example 1 Input: 7x7 grid with many colors: B, O, W, R, G, Y, A, X. Output: 3x3 grid with azure (A) and black (.). Let's examine the output:

Example 1 Output:
. . A
A A .
. A .

So 3x3 grid with azure at positions: (0,2), (1,0),(1,1),(2,1). That's a pattern.

Example 2 Output:
. A A
. A .
. A .

Positions: (0,1),(0,2),(1,1),(2,1). That's a different pattern.

Example 3 Output:
. . .
A A A
. . .

Positions: (1,0),(1,1),(1,2). That's a horizontal line.

So each species has a unique 3x3 pattern of azure. The pattern is fixed for each species. The output is the pattern for the dominant species.

Thus we need to determine which color appears most in the input grid. Then output the pattern associated with that color.

We need to deduce the mapping from color to pattern from the training examples.

We have 3 training examples. Let's analyze each.

Example 1 Input: Let's count each color.

Input grid:

Row0: B . B . O . .
Row1: B B W B . B .
Row2: . . B B . R .
Row3: . . . . G . B
Row4: . Y . B . . B
Row5: . . B . R . A
Row6: . . B . O G B

Let's count:

Colors: B, O, W, R, G, Y, A, X? Actually X appears? In example 1, I don't see X. Wait, there is no X in example 1. Colors present: B, O, W, R, G, Y, A. Let's count each:

- B: Let's count. Row0: B at (0,0) and (0,2) => 2. Row1: B at (1,0),(1,1),(1,3),(1,5) => 4. Row2: B at (2,2),(2,3) => 2. Row3: B at (3,6) => 1. Row4: B at (4,3),(4,6) => 2. Row5: B at (5,2) => 1. Row6: B at (6,2),(6,6) => 2. Total B = 2+4+2+1+2+1+2 = 14.

- O: Row0: O at (0,4) => 1. Row6: O at (6,5) => 1. Total O = 2.

- W: Row1: W at (1,2) => 1. Total W = 1.

- R: Row2: R at (2,5) => 1. Row5: R at (5,4) => 1. Total R = 2.

- G: Row3: G at (3,4) => 1. Row6: G at (6,5) => 1? Wait, row6 has G at (6,5). But we already counted O at (6,5). Actually row6: ". . B . O G B" => positions: (6,0)=., (6,1)=., (6,2)=B, (6,3)=., (6,4)=O, (6,5)=G, (6,6)=B. So G at (6,5). So G count: row3: G at (3,4) => 1. Row6: G at (6,5) => 1. Total G = 2.

- Y: Row4: Y at (4,1) => 1. Total Y = 1.

- A: Row5: A at (5,6) => 1. Total A = 1.

So B is dominant with 14. Output pattern: . . A / A A . / . A . . Wait, output is 3x3: row0: . . A, row1: A A ., row2: . A . . Wait, the output grid is 3x3, but the example shows 3 rows each with 3 characters. Let's confirm: Example 1 Output:
. . A
A A .
. A .

Yes, 3x3. So pattern for B is that.

Example 2 Input: Let's count.

Input grid:

Row0: . G . G X G .
Row1: . . G G . . .
Row2: A . . . . . G
Row3: G Y G W G . G
Row4: . . W G B G G
Row5: . G G G . G .
Row6: . . . . . . G

Colors present: G, X, A, Y, W, B. Let's count each.

- G: Count all G's. Row0: G at (0,1),(0,3),(0,5) => 3. Row1: G at (1,2),(1,3) => 2. Row2: G at (2,6) => 1. Row3: G at (3,0),(3,2),(3,4),(3,6) => 4. Row4: G at (4,3),(4,5),(4,6) => 3. Row5: G at (5,1),(5,2),(5,3),(5,5) => 4. Row6: G at (6,6) => 1. Total G = 3+2+1+4+3+4+1 = 18.

- X: Row0: X at (0,4) => 1. Total X = 1.

- A: Row2: A at (2,0) => 1. Total A = 1.

- Y: Row3: Y at (3,1) => 1. Total Y = 1.

- W: Row3: W at (3,3) => 1. Row4: W at (4,2) => 1. Total W = 2.

- B: Row4: B at (4,4) => 1. Total B = 1.

So G is dominant with 18. Output pattern: . A A / . A . / . A . . Wait, output is:

. A A
. A .
. A .

So pattern for G is that.

Example 3 Input: Let's count.

- R: Count all R's. Row0: R at (0,2) => 1. Row1: R at (1,2),(1,5) => 2. Row2: R at (2,0),(2,1),(2,2),(2,4) => 4. Row3: R at (3,1),(3,3),(3,5) => 3. Row4: R at (4,0),(4,1),(4,4),(4,5) => 4. Row5: R at (5,1),(5,2),(5,4) => 3. Row6: R at (6,3),(6,5),(6,6) => 3. Total R = 1+2+4+3+4+3+3 = 20.

We need to solve a grid transformation puzzle. We have training examples. We need to deduce the rule. Let's analyze.

We have a 7x7 input grid, and a 3x3 output grid. The output grid uses only a subset of colors: In example 1, output uses '.' and 'A' only. In example 2, output uses '.' and 'A' only. So output is a 3x3 grid of '.' and 'A' only. So the transformation likely selects a 3x3 subgrid from the input, or maybe a pattern of 'A's based on some rule.

The description: "What you see: A dense star field with stars of various spectral types. One class of star vastly outnumbers the rest, which appear as rare scattered points. What to do: Classify the stars and determine which spectral type dominates. Each dominant class triggers a specific constellation projection — a fixed pattern. Display it on the dome. Grid details: The star field is 7×7. The constellation projection is 3×3, illuminated in azure on the dark dome."

So we have a 7x7 grid of stars of various spectral types (colors). One class of star vastly outnumbers the rest, which appear as rare scattered points. So we need to find the dominant color (most frequent). Then each dominant class triggers a specific constellation projection — a fixed pattern. So for each dominant color, there is a fixed 3x3 pattern of azure (A) and black (.)? The output uses azure 'A' for the pattern. So the output is a 3x3 pattern of azure (A) and black (.) that corresponds to the dominant color.

Thus the rule: Determine the most frequent color in the 7x7 grid. Then output a 3x3 pattern that is predetermined for that color. The pattern is likely the same across all examples? But we only have two examples. Let's analyze the patterns.

Example 1 Input: 7x7 grid. Let's list the colors:

Row1: B . B . O . .
Row2: B B W B . B .
Row3: . . B B . R .
Row4: . . . . G . B
Row5: . Y . B . . B
Row6: . . B . R . A
Row7: . . B . O G B

We need to count each color frequency. Let's count:

Colors: B, O, W, R, G, Y, A, . (black). But '.' is background? The description says '.' = black. So black cells are background. The stars are colored cells. So we count only colored cells? But maybe we count all cells including '.'? But the dominant class likely refers to colored stars, not background. But we need to confirm.

Let's count colored cells:

Row1: B, B, O => 3 colored cells
Row2: B, B, W, B, B => 5 colored cells
Row3: B, B, R => 3 colored cells
Row4: G, B => 2 colored cells
Row5: Y, B, B => 3 colored cells
Row6: B, R, A => 3 colored cells
Row7: B, O, G, B => 4 colored cells

Total colored cells: 3+5+3+2+3+3+4 = 23 colored cells.

Now count each color:

B: Let's count. Row1: 2 B. Row2: 4 B. Row3: 2 B. Row4: 1 B. Row5: 2 B. Row6: 1 B. Row7: 3 B. Total B = 2+4+2+1+2+1+3 = 15 B.

O: Row1: 1 O. Row7: 1 O. Total O = 2.

W: Row2: 1 W. Total W = 1.

R: Row3: 1 R. Row6: 1 R. Total R = 2.

G: Row4: 1 G. Row7: 1 G. Total G = 2.

Y: Row5: 1 Y. Total Y = 1.

A: Row6: 1 A. Total A = 1.

So B is dominant with 15 occurrences. So the dominant class is B.

Now the output pattern is:

. . A
A A .
. A .

Let's write as 3x3 grid:

Row1: . . A
Row2: A A .
Row3: . A .

So the pattern for B is this pattern.

Now Example 2 Input: Let's analyze.

Input grid:

Row1: . G . G X G .
Row2: . . G G . . .
Row3: A . . . . . G
Row4: G Y G W G . G
Row5: . . W G B G G
Row6: . G G G . G .
Row7: . . . . . . G

We need to count colored cells.

Row1: G, G, X, G => 4 colored cells
Row2: G, G => 2 colored cells
Row3: A, G => 2 colored cells
Row4: G, Y, G, W, G, G => 6 colored cells
Row5: W, G, B, G, G => 5 colored cells
Row6: G, G, G, G => 4 colored cells
Row7: G => 1 colored cell

Total colored cells: 4+2+2+6+5+4+1 = 24 colored cells.

Now count each color:

G: Let's count. Row1: 3 G. Row2: 2 G. Row3: 1 G. Row4: 4 G (positions 1,3,5,7). Row5: 3 G (positions 4,6,7). Row6: 4 G (positions 2,3,4,6). Row7: 1 G. Total G = 3+2+1+4+3+4+1 = 18 G.

X: Row1: 1 X. Total X = 1.

A: Row3: 1 A. Total A = 1.

Y: Row4: 1 Y. Total Y = 1.

W: Row4: 1 W. Row5: 1 W. Total W = 2.

B: Row5: 1 B. Total B = 1.

So G is dominant with 18 occurrences.

Output pattern for G is:

. A A
. A .
. A .

Let's write as 3x3 grid:

Row1: . A A
Row2: . A .
Row3: . A .

So the pattern for G is this pattern.

Thus we have two patterns: For B: pattern1; For G: pattern2.

Now we need to deduce the mapping from color to pattern. There might be a fixed mapping for each color. But we only have two colors. But maybe the mapping is based on something else: maybe the pattern is derived from the arrangement of the dominant color in the 7x7 grid? But the output patterns are fixed 3x3 patterns of azure and black. They might be derived from the shape of the dominant color cluster? But the patterns are not obviously derived from the input shape. Let's examine.

For B: pattern1:

. . A
A A .
. A .

For G: pattern2:

. A A
. A .
. A .

Let's see if these patterns correspond to some shape like a cross or something. Let's o

We need to solve a grid transformation puzzle. We have training examples. We need to deduce the rule. Let's parse the problem.

We have a 7x7 input grid, and a 3x3 output grid. The description: "What you see: A busy harbor where ships fly flags of many nations. One fleet vastly outnumbers the others, while a few foreign vessels dot the anchorage. What to do: Survey the harbor and identify the dominant fleet by flag count. Each fleet has a unique signal pennant pattern. The harbormaster hoists that pennant. Grid details: The harbor is 7×7. The signal pennant is 3×3, stitched in azure on a dark field."

So we have a 7x7 grid of colors. We need to find the dominant fleet by flag count. Each fleet has a unique signal pennant pattern. The harbormaster hoists that pennant. The output is a 3x3 grid of colors, presumably the pattern of the dominant fleet's pennant. The output is azure (A) on a dark field? Wait: "The signal pennant is 3×3, stitched in azure on a dark field." So the output is a 3x3 grid with azure (A) and dark field (maybe black '.'? But the output examples show '.' and 'A' only. Let's examine training examples.

Example 1 Input: 7x7 grid with many colors: B, ., O, W, R, G, Y, A. Output: 3x3 grid with '.' and 'A' only. Let's examine the output:

Example 1 Output:
. . A
A A .
. A .

So output grid has '.' and 'A' only. So azure 'A' cells correspond to the pattern of the dominant fleet's pennant. The rest of the output cells are '.' (black). So the output is a 3x3 pattern of azure cells (A) and black cells (.) representing the pennant.

Thus the rule: find the color that appears most frequently in the 7x7 grid (dominant fleet). Then find the 3x3 pattern of that color in the grid? Wait: The output pattern is azure on a dark field. The azure cells correspond to the pattern of the dominant fleet's pennant. But the output pattern is not necessarily the same as the arrangement of that color in the input grid. It might be the shape of the dominant color's cluster? Let's analyze.

Example 1 Input: Let's list coordinates of each color. We'll need to parse the grid.

Example 1 Input grid:

Row1: B . B . O . .
Row2: B B W B . B .
Row3: . . B B . R .
Row4: . . . . G . B
Row5: . Y . B . . B
Row6: . . B . R . A
Row7: . . B . O G B

Let's index rows 1-7, columns 1-7.

We need to find the dominant color. Let's count each color:

Colors present: B, O, W, R, G, Y, A. Also '.' (black). Let's count.

We'll count each color:

Initialize counts: B:0, O:0, W:0, R:0, G:0, Y:0, A:0.

Row1: B . B . O . . => B:2, O:1
Row2: B B W B . B . => B:5 (2+3?), let's count: B at col1, col2, col4, col6 => 4 B's. So B:2+4=6. W:1
Row3: . . B B . R . => B at col3, col4 => +2 => B:8. R:1
Row4: . . . . G . B => G:1, B:1 => B:9
Row5: . Y . B . . B => Y:1, B at col4, col7 => +2 => B:11
Row6: . . B . R . A => B:1 => B:12, R:1 => R:2, A:1
Row7: . . B . O G B => B at col3, col7 => +2 => B:14, O:1 => O:2, G:1 => G:2

So counts: B:14, O:2, W:1, R:2, G:2, Y:1, A:1. Dominant color: B (blue). So the dominant fleet is blue.

Now the output pattern: 3x3 grid with azure cells (A) and black cells (.). But azure cells correspond to the pattern of the dominant fleet's pennant. But azure is not blue; azure is a different color. So the output pattern is azure cells representing the shape of the dominant fleet's pennant. But the shape is derived from the arrangement of the dominant color in the input grid? Let's examine the arrangement of B cells in the input grid. Maybe the shape of the dominant color's cluster is a 3x3 pattern? Let's see.

We need to find a 3x3 subgrid that contains the most B cells? Or maybe the 3x3 subgrid that has the highest count of B cells? Let's examine all possible 3x3 subgrids in the 7x7 grid. There are 5x5 = 25 possible 3x3 subgrids. For each subgrid, we can count the number of B cells. The subgrid with the maximum B count might be the dominant fleet's pennant pattern. Then we output a 3x3 grid where azure cells correspond to B cells in that subgrid, and black cells correspond to non-B cells. Let's test this hypothesis.

We need to find the 3x3 subgrid with the maximum B count. Let's compute.

We'll label coordinates (row, col). Let's list B positions:

Row1: col1, col3
Row2: col1, col2, col4, col6
Row3: col3, col4
Row4: col7
Row5: col4, col7
Row6: col3
Row7: col3, col7

So B positions: (1,1),(1,3),(2,1),(2,2),(2,4),(2,6),(3,3),(3,4),(4,7),(5,4),(5,7),(6,3),(7,3),(7,7). 14 positions.

Now we need to find a 3x3 subgrid that contains the most of these B positions. Let's examine each possible top-left coordinate (r,c) where r=1..5, c=1..5.

We'll compute B counts for each subgrid.

We can do manual enumeration.

Define subgrid (r,c) includes rows r,r+1,r+2 and columns c,c+1,c+2.

Let's create a table.

We'll compute B counts.

We'll list B positions again for quick reference:

(1,1)
(1,3)
(2,1)
(2,2)
(2,4)
(2,6)
(3,3)
(3,4)
(4,7)
(5,4)
(5,7)

We need to solve a grid transformation puzzle. We have training examples. We need to deduce the rule. Let's analyze.

We have 7x7 input grids and 3x3 output grids. The output grid is 3x3. The output grid uses only colors A, B, G, R, Y, X, etc? Let's check training outputs.

Example 1 output:
```
. . A
A A .
. A .
```
So output uses only A and . (black). Example 2 output:
```
. A A
. A .
. A .
```
Also only A and . . So output is a 3x3 pattern of A's and . (black). So the output is a pattern of azure (A) lights on a dark panel. The puzzle description: "diagnostic display is 3×3, lit in azure on a dark panel." So output is azure pattern.

So the rule: from 7x7 input grid, we need to produce a 3x3 pattern of azure (A) lights. The azure pattern corresponds to the dominant frequency? The metaphor: "What you see: A noisy circuit board carrying signals across many frequency bands. One frequency appears on far more traces than the others, which register as faint noise. What to do: Analyze the signal spectrum and identify the dominant frequency. Each frequency is mapped to a unique diagnostic LED pattern — a fixed indicator shape. Light up that pattern."

So we need to identify the dominant frequency among the colors? The input grid has many colors: B, R, G, Y, X, M, O, A, W. The output pattern is a 3x3 pattern of azure (A). The azure pattern corresponds to the dominant frequency. So we need to find which color appears most frequently in the input grid. Then map that color to a 3x3 pattern. The mapping is fixed: each color maps to a unique 3x3 pattern of azure lights. The output pattern is the pattern for the dominant color.

Thus we need to deduce the mapping from colors to 3x3 patterns from the training examples.

We have two training examples. In each, we can compute the frequency of each color in the input grid. Then find the dominant color. Then see the output pattern. That will give us mapping for that color.

Let's analyze Example 1.

Example 1 Input grid (7x7):

Row1: B . B . O . .
Row2: B B W B . B .
Row3: . . B B . R .
Row4: . . . . G . B
Row5: . Y . B . . B
Row6: . . B . R . A
Row7: . . B . O G B

Let's count each color: B, O, W, R, G, Y, A. Also maybe . (black). Let's count.

I'll write coordinates. Let's count manually.

Row1: B . B . O . . => B:2, O:1
Row2: B B W B . B . => B:4, W:1
Row3: . . B B . R . => B:2, R:1
Row4: . . . . G . B => G:1, B:1
Row5: . Y . B . . B => Y:1, B:2
Row6: . . B . R . A => B:1, R:1, A:1
Row7: . . B . O G B => B:2, O:1, G:1

Now sum:

B: row1 2 + row2 4 + row3 2 + row4 1 + row5 2 + row6 1 + row7 2 = 14? Let's sum: 2+4=6, +2=8, +1=9, +2=11, +1=12, +2=14. Yes B=14.

O: row1 1 + row7 1 = 2.

W: row2 1 = 1.

R: row3 1 + row6 1 = 2.

G: row4 1 + row7 1 = 2.

Y: row5 1 = 1.

A: row6 1 = 1.

So B is dominant with 14 occurrences. So the output pattern corresponds to color B.

Now the output pattern is:

```
. . A
A A .
. A .
```

So the pattern for B is that shape.

Now Example 2.

Example 2 Input grid:

Row1: . G . G X G .
Row2: . . G G . . .
Row3: A . . . . . G
Row4: G Y G W G . G
Row5: . . W G B G G
Row6: . G G G . G .
Row7: . . . . . . G

Let's count colors: G, X, A, Y, W, B. Also maybe . (black). Let's count.

Row1: . G . G X G . => G:3, X:1
Row2: . . G G . . . => G:2
Row3: A . . . . . G => A:1, G:1
Row4: G Y G W G . G => G:4, Y:1, W:1
Row5: . . W G B G G => W:1, G:3, B:1
Row6: . G G G . G . => G:4
Row7: . . . . . . G => G:1

Now sum:

G: row1 3 + row2 2 + row3 1 + row4 4 + row5 3 + row6 4 + row7 1 = 18? Let's sum: 3+2=5, +1=6, +4=10, +3=13, +4=17, +1=18. Yes G=18.

X: row1 1 = 1.

A: row3 1 = 1.

Y: row4 1 = 1.

W: row4 1 + row5 1 = 2.

B: row5 1 = 1.

So G is dominant with 18 occurrences. So the output pattern corresponds to color G.

Output pattern for Example 2:

```
. A A
. A .
. A .
```

So the pattern for G is that shape.

Thus we have mapping:

Color B -> pattern:
```
. . A
A A .
. A .
```

Color G -> pattern:
```
. A A
. A .
. A .
```

Now we need to produce output for test input. We need to find the dominant color in test input. Then output the corresponding pattern.

But we only have mapping for B and G. The test input may have a different dominant color. We need to deduce mapping for other colors? But maybe the dominant color will be B or G again. Let's check test input.

Test Input grid:

Row1: G . G . . . G
Row2: G . W X . . X
Row3: . G . G . R W
Row4: A G . G . . O
Row5: . G X . . G G
Row6: . . G G . . .
Row7: . . G . Y . .

Let's count colors: G, W, X, R, O, A, Y. Also maybe . (black). Let's count.

Row1: G . G . . . G => G:3
Row2: G . W X . . X => G:1, W:1, X:2
Row3: . G . G . R W => G:2, R:1, W:1
Row4: A G . G . . O => A:1, G:2, O:1
Row5: . G X . . G G => G:3, X:1
Row6: . . G G . . . => G:2
Row7: . . G . Y . . => G:1, Y:1

Now sum:

G: row1 3 + row2 1 + row3 2 + row4 2 + row5 3 + row6 2 + row7 1 = 14? Let's sum: 3+1=4, +2=6, +2=8, +3=11, +2=13, +1=14. Yes G=14.

We need to solve a grid transformation puzzle. We have training examples. We need to deduce the rule. Let's analyze.

We have 7x7 input grids and 3x3 output grids. The output grid is 3x3. The description: "What you see: A sacred grove alive with many spiritual presences. One spirit manifests far more intensely than the others, whose traces are faint and scattered. What to do: Sense which spirit dominates the grove. Each spirit, when it prevails, inscribes its personal rune on the altar — a compact, fixed glyph. Read the glowing rune. Grid details: The grove is 7×7. The altar rune is 3×3, glowing azure on dark stone."

So we need to find which spirit dominates the grove. Each spirit, when it prevails, inscribes its personal rune on the altar — a compact, fixed glyph. So the output is a 3x3 glyph that corresponds to the dominant spirit. The glyph is "glowing azure" (color A). So the output grid is 3x3 with azure cells? Wait the output examples show azure cells (A) and black cells (.). Let's examine Example 1 output:

Example 1 Output:
. . A
A A .
. A .

So 3x3 grid with azure cells at positions: (0,2), (1,0),(1,1),(2,1). That's a shape. Example 2 Output:
. A A
. A .
. A .

Positions: (0,1),(0,2),(1,1),(2,1). That's a shape similar but rotated? Let's compare shapes.

Example 1 shape: coordinates (0,2),(1,0),(1,1),(2,1). Example 2 shape: (0,1),(0,2),(1,1),(2,1). So they differ: Example 1 has an extra cell at (1,0) and missing at (0,1). Example 2 has extra at (0,1) and missing at (1,0). So shapes differ. So the glyph depends on which spirit dominates. So we need to identify the dominant spirit in the input grid. The dominant spirit is the one that manifests far more intensely than others, whose traces are faint and scattered. So we need to find which color appears most frequently? But the description says "One spirit manifests far more intensely than the others, whose traces are faint and scattered." So maybe the dominant spirit is the one that appears most often in the grid. But we need to confirm with training examples.

Let's analyze Example 1 input grid:

Example 1 Input (7x7):
Row0: B . B . O . .
Row1: B B W B . B .
Row2: . . B B . R .
Row3: . . . . G . B
Row4: . Y . B . . B
Row5: . . B . R . A
Row6: . . B . O G B

Let's count each color frequency:

Colors: B, O, W, R, G, Y, A. Let's count.

Row0: B, B, O => B:2, O:1
Row1: B,B,W,B,B => B:4, W:1
Row2: B,B,R => B:2, R:1
Row3: G,B => G:1, B:1
Row4: Y,B,B => Y:1, B:2
Row5: B,R,A => B:1, R:1, A:1
Row6: B,O,G,B => B:2, O:1, G:1

Now sum B: 2+4+2+1+2+1+2 = 14? Wait let's sum carefully: Row0 B:2, Row1 B:4 => 6, Row2 B:2 => 8, Row3 B:1 => 9, Row4 B:2 => 11, Row5 B:1 => 12, Row6 B:2 => 14. So B appears 14 times.

O: Row0 1, Row6 1 => 2
W: Row1 1 => 1
R: Row2 1, Row5 1 => 2
G: Row3 1, Row6 1 => 2
Y: Row4 1 => 1
A: Row5 1 => 1

So B is dominant with 14 occurrences. So the dominant spirit is B (blue). The output glyph shape for B is the shape in Example 1 output. So the glyph for B is that shape.

Now Example 2 input grid:

Example 2 Input:
Row0: . G . G X G .
Row1: . . G G . . .
Row2: A . . . . . G
Row3: G Y G W G . G
Row4: . . W G B G G
Row5: . G G G . G .
Row6: . . . . . . G

Count colors: G, X, A, Y, W, B. Let's count.

Row0: G, G, X, G => G:3, X:1
Row1: G, G => G:2
Row2: A, G => A:1, G:1
Row3: G, Y, G, W, G, G => G:4, Y:1, W:1
Row4: W, G, B, G, G => W:1, G:4, B:1
Row5: G, G, G, G => G:4
Row6: G => G:1

Now sum G: Row0 3 + Row1 2 + Row2 1 + Row3 4 + Row4 4 + Row5 4 + Row6 1 = 19? Let's sum: 3+2=5, +1=6, +4=10, +4=14, +4=18, +1=19. So G appears 19 times.

X: 1
A: 1
Y: 1
W: 2? Wait W appears Row3 1, Row4 1 => 2
B: 1

So G is dominant with 19 occurrences. So the dominant spirit is G (green). The output glyph shape for G is the shape in Example 2 output. So the glyph for G is that shape.

Thus the rule: Identify the color that appears most frequently in the 7x7 grid. Then output a 3x3 glyph that corresponds to that color. The glyph is predetermined for each color. We need to deduce the glyph mapping for each color. We have glyphs for B and G. We need to produce glyph for the dominant color in test input. The test input likely has a dominant color. We need to find which color appears most. Then we need to output the glyph for that color. But we only have glyphs for B and G. We need to deduce glyphs for other colors? But maybe the test input's dominant color is either B or G, so we can use the known glyph. Let's check test input.

Test Input:
Row0: G . G . . . G
Row1: G . W X . . X
Row2: . G . G . R W

We need to solve a grid transformation puzzle. We have training examples. We need to deduce the rule. Let's analyze.

We have a 7x7 input grid, and a 3x3 output grid. The output grid uses only a subset of colors: A, maybe others? In example 1 output: 
```
. . A
A A .
. A .
```
So output uses only '.' and 'A'. Example 2 output:
```
. A A
. A .
. A .
```
Also only '.' and 'A'.

So the transformation likely selects a 3x3 subgrid from the 7x7 input, maybe based on some rule, and then transforms it to output. The output uses only '.' and 'A', maybe representing presence of a particular color in the subgrid? The description: "What you see: A geological cross-section showing many mineral types embedded in rock. One mineral is pervasive throughout the sample, while others appear as rare inclusions. What to do: Examine the sample and identify the dominant mineral by abundance. Each mineral, when dominant, produces a characteristic crystal habit — a fixed geometric form. Sketch it in the notebook. Grid details: The core sample is 7×7. The crystal habit sketch is 3×3, drawn in azure on a dark page."

Interpretation: The input grid is a 7x7 cross-section with many colors representing minerals. One mineral is pervasive throughout the sample, while others appear as rare inclusions. The task: identify the dominant mineral by abundance. Each mineral, when dominant, produces a characteristic crystal habit — a fixed geometric form. Sketch it in the notebook. The output grid is 3x3, drawn in azure on a dark page. So the output grid is a 3x3 representation of the crystal habit of the dominant mineral, drawn in azure (color A). The output grid uses '.' for background (dark page) and 'A' for azure lines. So the output is a 3x3 pattern of azure cells representing the crystal habit shape of the dominant mineral.

Thus the transformation: find the color that appears most frequently in the 7x7 input grid. Then find the 3x3 pattern that best matches the arrangement of that color in the input? Or maybe the 3x3 pattern is the shape of the dominant mineral's crystal habit, which is predetermined for each color. But we only have two training examples, so we need to deduce the mapping from color to 3x3 pattern. The output patterns are:

Example 1 output:
```
. . A
A A .
. A .
```
Example 2 output:
```
. A A
. A .
. A .
```

We need to see which color is dominant in each input, and then see if the output pattern corresponds to that color's predetermined habit.

Let's analyze Example 1 input:

Example 1 Input grid (7x7):
Row1: B . B . O . .
Row2: B B W B . B .
Row3: . . B B . R .
Row4: . . . . G . B
Row5: . Y . B . . B
Row6: . . B . R . A
Row7: . . B . O G B

Let's count each color frequency:

Colors: B, O, W, R, G, Y, A. Also '.'.

Count B: Let's count manually.

Row1: B at col1, B at col3 => 2
Row2: B at col1, col2, col4, col6 => 4
Row3: B at col3, col4 => 2
Row4: B at col8? Wait row4 has 7 columns: row4: . . . . G . B. So B at col7 => 1
Row5: B at col4, col7 => 2
Row6: B at col7 => 1
Row7: B at col7 => 1

Total B: 2+4+2+1+2+1+1 = 13

Count O: Row1 col5 => 1; Row7 col5 => 1; Row7 col? Wait row7: . . B . O G B => O at col5 => 1. Row1 col5 => 1. Row7 col5 => 1. Row7 col? Actually row7 col5 is O. Row7 col? There's also O at row7 col5. Row7 col? Wait row7 col5 is O. Row7 col? There's also O at row7 col5. Row7 col? There's also O at row7 col5. Row7 col? There's also O at row7 col5. Row7 col? I'm repeating. Let's just count: Row1: O at col5 => 1. Row7: O at col5 => 1. Row7: O at col5. Row7: O at col5. Row7: O at col5. Row7: O at col5. Row7: O at col5. Row7: O at col5. Row7: O at col5.

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A bubbling pot with many ingredients, but one flavor dominates the broth. Other seasonings — a pinch here, a dash there — are barely noticeable by comparison. What to do: Taste the stew and identify the overwhelming ingredient. Each dominant flavor has a traditional plating style — a specific arrangement of garnish on a small square plate. Present the garnish that corresponds to whatever took over the dish. Grid details: The stew pot is a 7×7 arrangement of ingredients. The plate is always 3×3, garnished in azure on a clean dark surface."

We have training examples. We need to deduce the transformation rule. Let's analyze the training examples.

Example 1:

Input grid 7x7:

Row1: B . B . O . .
Row2: B B W B . B .
Row3: . . B B . R .
Row4: . . . . G . B
Row5: . Y . B . . B
Row6: . . B . R . A
Row7: . . B . O G B

Output grid 3x3:

Row1: . . A
Row2: A A .
Row3: . A .

We need to find rule mapping input to output. Let's analyze colors: B=blue, W=maroon? Wait W=maroon. Actually W=maroon. But we have W in input. Also O=orange, Y=yellow, R=red, G=green, X=grey, A=azure. Output uses only A and . (black). So output is 3x3 with azure cells and black cells. The output pattern seems to be a shape of azure cells. The azure cells correspond to something in input. The metaphor: "dominant flavor" is the color that dominates the broth. The output is a 3x3 plate garnished in azure on a clean dark surface. So the output is a 3x3 grid with azure cells representing the garnish arrangement for the dominant flavor. So we need to find the dominant color in the input grid, then produce a 3x3 pattern that corresponds to that color. The pattern is predetermined for each color. The output pattern is the "traditional plating style" for that dominant flavor. So we need to deduce mapping from color to 3x3 pattern.

We have two training examples. Let's analyze them.

Example 1: Input grid has many colors: B, O, W, R, G, Y, A. We need to find the dominant color. Let's count occurrences of each color.

We'll parse the grid:

Row1: B . B . O . . => B:2, O:1
Row2: B B W B . B . => B:4, W:1
Row3: . . B B . R . => B:2, R:1
Row4: . . . . G . B => G:1, B:1
Row5: . Y . B . . B => Y:1, B:2
Row6: . . B . R . A => B:1, R:1, A:1
Row7: . . B . O G B => B:2, O:1, G:1

Now sum:

B: 2+4+2+1+2+1+2 = 14? Let's compute: Row1 2, Row2 4 => 6, Row3 2 => 8, Row4 1 => 9, Row5 2 => 11, Row6 1 => 12, Row7 2 => 14. Yes B=14.

O: Row1 1, Row7 1 => 2.

W: Row2 1 => 1.

R: Row3 1, Row6 1 => 2.

G: Row4 1, Row7 1 => 2.

Y: Row5 1 => 1.

A: Row6 1 => 1.

So B is dominant with 14 occurrences. So the dominant flavor is blue (B). The output pattern is azure cells arranged in a shape. But azure is A. So the output uses azure cells to represent the garnish for the dominant flavor. So the output pattern is predetermined for blue. Let's examine the output pattern:

Output 3x3:

Row1: . . A
Row2: A A .
Row3: . A .

So azure cells at positions: (1,3), (2,1), (2,2), (3,2). That's a shape like a cross? Let's map coordinates: using 1-indexed rows and columns.

Positions:

(1,3)
(2,1)
(2,2)
(3,2)

This shape looks like a T shape rotated? Let's visualize:

Row1: . . A
Row2: A A .
Row3: . A .

So pattern:

Row1: ..A
Row2: AA.
Row3: .A.

This is like a "zigzag" shape? Let's see if we can find a pattern for each color.

Example 2:

Input grid 7x7:

Row1: . G . G X G .
Row2: . . G G . . .
Row3: A . . . . . G
Row4: G Y G W G . G
Row5: . . W G B G G
Row6: . G G G . G .
Row7: . . . . . . G

Output 3x3:

Row1: . A A
Row2: . A .
Row3: . A .

So azure cells at positions: (1,2), (1,3), (2,2), (3,2). That's a vertical line of 3 azure cells at column 2, plus one at (1,3). Wait let's list:

Row1: . A A => azure at (1,2), (1,3)
Row2: . A . => azure at (2,2)
Row3: . A . => azure at (3,2)

So shape: a vertical line of 3 azure cells at column 2, plus an extra azure at (1,3). So shape looks like a "T" rotated? Actually it's like a vertical line with a horizontal bar at top right. Let's visualize:

Row1: ..? Actually row1: . A A => positions (1,2),(1,3)
Row2: . A . => (2,2)
Row3: . A . => (3,2)

So shape: a vertical line at column 2 from rows 1-3, plus a horizontal bar at top row from columns 2-3. So shape like a "Γ" shape? Let's think.

Now we need to find the dominant color in Example 2. Let's count occurrences.

Input grid:

Row1: . G . G X G . => G:3, X:1
Row2: . . G G . . . => G:2
Row3: A . . . . . G => A:1, G:1
Row4: G Y G W G . G => G:4, Y:1, W:1
Row5: . . W G B G G => W:1, G:3, B:1
Row6: . G G G . G . => G:4
Row7: . . . . . . G => G:1

Now sum:

G: Row1 3, Row2 2 => 5, Row3 1 => 6, Row4 4 => 10, Row5 3 => 13, Row6 4 => 17, Row7 1 => 18. So G=18.

Y: 1
W: 2? Wait W appears in Row4 1, Row5 1 => 2.
B: 1
X: 1
A: 1

So G is dominant with 18 occurrences. So

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A chaotic warm-up where many instruments play simultaneously. One instrumental section is far louder and more numerous than the scattered soloists from other sections. What to do: Listen for which section dominates the soundscape. The conductor responds with a specific baton gesture — a compact motion pattern unique to that instrument family. Transcribe the gesture. Grid details: The orchestra pit is 7×7. The conductor's gesture is a 3×3 notation in azure on silence."

We have training examples. We need to deduce the transformation rule. Let's analyze the examples.

Example 1:

Input grid 7x7:

Row1: B . B . O . .
Row2: B B W B . B .
Row3: . . B B . R .
Row4: . . . . G . B
Row5: . Y . B . . B
Row6: . . B . R . A
Row7: . . B . O G B

Output grid 3x3:

. . A
A A .
. A .

We need to find rule mapping input to output. The output is 3x3 azure (A) pattern on silence (.). The output pattern is a 3x3 shape of azure cells. The output pattern appears to be a shape of azure cells that correspond to something in the input. The description: "One instrumental section is far louder and more numerous than the scattered soloists from other sections." So we need to find the color that appears most frequently in the input grid. That color is the dominant instrument. Then we need to produce a 3x3 pattern that is a "compact motion pattern unique to that instrument family." So maybe we need to produce a 3x3 pattern that is the shape of the most frequent color's arrangement? Or maybe we need to produce a 3x3 pattern that is the shape of the most frequent color's bounding box? Or maybe we need to produce a 3x3 pattern that is the shape of the most frequent color's "motion pattern" (like a 3x3 pattern that is the most common 3x3 subgrid of that color?). Let's analyze.

We need to examine the input grid for Example 1. Let's count each color frequency.

Colors: B, O, W, R, G, Y, A, X? Actually X appears? In Example 1, I see B, O, W, R, G, Y, A. No X. Let's count.

Row1: B . B . O . . => B:2, O:1
Row2: B B W B . B . => B:4, W:1
Row3: . . B B . R . => B:2, R:1
Row4: . . . . G . B => G:1, B:1
Row5: . Y . B . . B => Y:1, B:2
Row6: . . B . R . A => B:1, R:1, A:1
Row7: . . B . O G B => B:2, O:1, G:1

Now sum B: row1 2 + row2 4 + row3 2 + row4 1 + row5 2 + row6 1 + row7 2 = 14 B's. O: row1 1 + row7 1 = 2 O's. W: 1. R: row3 1 + row6 1 = 2 R's. G: row4 1 + row7 1 = 2 G's. Y: 1. A: 1. So B is dominant with 14. So the dominant color is B.

Now the output grid is 3x3 with azure (A) cells. So azure is the output color. The output pattern is:

Row1: . . A
Row2: A A .
Row3: . A .

So azure cells at positions: (1,3), (2,1), (2,2), (3,2). That's a shape like a small cross? Actually shape: coordinates (row, col) 1-indexed: (1,3), (2,1), (2,2), (3,2). That's like a shape of 4 cells forming a "T" shape rotated? Let's visualize:

Row1: . . A
Row2: A A .
Row3: . A .

So shape:

```
  . . A
  A A .
  . A .
```

This shape is like a "zigzag" or "L" shape? Let's see: It's like a 3x3 pattern with 4 azure cells. The shape is symmetrical? Not symmetrical. Let's check if this shape corresponds to the arrangement of B's in the input? Maybe the shape is the 3x3 bounding box of the B's? But B's are many across the grid. The bounding box of B's would be from row1 to row7, col1 to col7. That's the whole grid. So not that.

Maybe the shape is the 3x3 pattern that appears most frequently in the input grid for the dominant color? Let's examine all 3x3 subgrids of the input grid that contain B's. But there are many. But maybe we need to find the 3x3 subgrid that has the most B's? Or the subgrid that has the most B's relative to other colors? But the output pattern is azure cells, not B. So maybe we need to produce a 3x3 pattern that is the shape of the most common 3x3 pattern of B's? But the output pattern is azure cells, not B. So maybe we need to produce a 3x3 pattern that is the shape of the "motion pattern" of the dominant color, but we output it in azure on silence. So we need to find the shape of the dominant color's "motion pattern" (like the arrangement of B's relative to each other). But the output pattern is only 4 azure cells. So maybe the shape is the shape of the "most common 3x3 pattern" of B's? But we need to check.

Let's analyze Example 2.

Example 2 Input:

Row1: . G . G X G .
Row2: . . G G . . .
Row3: A . . . . . G
Row4: G Y G W G . G
Row5: . . W G B G G
Row6: . G G G . G .
Row7: . . . . . . G

Output:

. A A
. A .
. A .

So output 3x3 azure pattern:

Row1: . A A
Row2: . A .
Row3: . A .

Positions: (1,2), (1,3), (2,2), (3,2). That's a vertical line of 3 azure cells at column 2, plus one at (1,3). Actually shape: a vertical line of 3 cells at column 2, plus one at (1,3). So shape:

```
. A A
. A .
. A .
```

This shape is like a "T" shape rotated? Actually it's like a vertical line with a cell to the right at the top. So

We need to solve a puzzle. We have a grid transformation puzzle. The description: "What you see: A satellite view shows a region with many competing weather systems. One type of front covers far more area than the scattered pockets of other conditions. What to do: Read the dominant weather pattern across the map. Each type of dominant front produces a characteristic forecast symbol — a compact icon. Display that icon on the forecast board. Grid details: The weather map spans a 7×7 region. The forecast icon is a 3×3 symbol rendered in azure on a dark bulletin board."

We have training examples. We need to deduce the transformation rule. Let's analyze the training examples.

We have 7x7 input grids, and 3x3 output grids. The output grid uses only '.' and 'A' in examples? Let's check.

Example 1 Input: 7x7 grid with colors: B, ., O, W, R, G, Y, X, A. Output: 3x3 grid with '.' and 'A' only. Example 2: Output also '.' and 'A'. Example 3: Output also '.' and 'A'. So output is a 3x3 grid of '.' and 'A' only. So the transformation reduces the 7x7 grid to a 3x3 grid of azure (A) and black (.) cells. The azure cells correspond to the dominant weather pattern across the map. The description: "Read the dominant weather pattern across the map. Each type of dominant front produces a characteristic forecast symbol — a compact icon. Display that icon on the forecast board." So we need to find the dominant weather pattern across the map. The dominant front type covers far more area than the scattered pockets of other conditions. So we need to find the color that appears most frequently in the 7x7 grid. That is the dominant front. Then we need to produce a 3x3 icon that corresponds to that front type. Each type of dominant front produces a characteristic forecast symbol — a compact icon. So each color has a unique 3x3 pattern of azure cells. The output is that pattern. So we need to map each color to a 3x3 pattern. The training examples show patterns for some colors. Let's analyze.

Example 1 Input: Let's count colors. Input grid:

Row1: B . B . O . .
Row2: B B W B . B .
Row3: . . B B . R .
Row4: . . . . G . B
Row5: . Y . B . . B
Row6: . . B . R . A
Row7: . . B . O G B

Let's count each color: B, O, W, R, G, Y, A. Let's count B: row1: 2 B; row2: 4 B? Wait row2: B B W B . B . => B at positions 1,2,4,6 => 4 B. Row3: . . B B . R . => 2 B. Row4: . . . . G . B => 1 B. Row5: . Y . B . . B => 2 B. Row6: . . B . R . A => 1 B. Row7: . . B . O G B => 2 B. Total B = 2+4+2+1+2+1+2 = 14 B. O: row1: O at col5 => 1. Row7: O at col5 => 1. So O=2. W: row2: W at col3 => 1. R: row3: R at col6 => 1. Row6: R at col5 => 1. So R=2. G: row4: G at col5 => 1. Row7: G at col6 => 1. So G=2. Y: row5: Y at col2 => 1. A: row6: A at col7 => 1. So B is dominant with 14 cells. So the output pattern should correspond to B. The output grid is:

. . A
A A .
. A .

Let's write that as 3x3:

Row1: . . A
Row2: A A .
Row3: . A .

So that's the pattern for B.

Example 2 Input: Let's count colors. Input grid:

Row1: . G . G X G .
Row2: . . G G . . .
Row3: A . . . . . G
Row4: G Y G W G . G
Row5: . . W G B G G
Row6: . G G G . G .
Row7: . . . . . . G

Colors: G, X, A, Y, W, B. Let's count G: many. Let's count each.

Row1: G at col2, col4, col6 => 3 G.
Row2: G at col3, col4 => 2 G.
Row3: G at col7 => 1 G.
Row4: G at col1, col3, col5, col7 => 4 G.
Row5: G at col4, col6, col7 => 3 G.
Row6: G at col2, col3, col4, col6 => 4 G.
Row7: G at col7 => 1 G.
Total G = 3+2+1+4+3+4+1 = 18 G.

X: row1: X at col5 => 1 X. Row? None else. So X=1.

A: row3: A at col1 => 1 A.

Y: row4: Y at col2 => 1 Y.

W: row4: W at col4 => 1 W. Row5: W at col3 => 1 W. So W=2.

B: row5: B at col5 => 1 B.

So G is dominant with 18 cells. Output pattern is:

. A A
. A .
. A .

Let's write that:

Row1: . A A
Row2: . A .
Row3: . A .

So that's the pattern for G.

Example 3 Input: Let's count colors. Input grid:

Row1: . . R . B X G
Row2: . . R W . R .
Row3: R R R Y R . .
Row4: . R . R O R .
Row5: R R . . R R M

Row7: X . Y R . R R

Colors: R, B, X, G, W, Y, O, M. Let's count R: many. Let's count each.

Row1: R at col3 => 1 R. Row1: B at col5, X at col6, G at col7. Row2: R at col3, W at col4, R at col6 => 2 R. Row3: R at col1, col2, col3, col5 => 4 R. Row4: R at col2, col4, col6 => 3 R. Row5: R at col1, col2, col5, col6 => 4 R. Row6: R at col2, col3, col5 => 3 R. Row7: R at col4, col6, col7 => 3 R. Total R = 1+2+4+3+4+3+3 = 20 R.

B: row1: B at col5 => 1 B. Row? None else. So B=1.

X: row1: X at col6 => 1 X. Row7: X at col1 => 1 X. So X=2.

G: row1: G at col7 => 1 G. Row? None else. So G=1.

W: row2: W at col4 => 1 W. So W=1.

Y: row3: Y at col4 => 1 Y. Row7: Y at col3 => 1 Y. So Y=2.

O: row4: O at col5 => 1 O. So O=1.

M: row5: M at col7 => 1 M. So M=1.

So R is dominant with 20 cells. Output pattern is:

We need to solve a grid transformation puzzle. We have training examples with input 7x7 grids and output 3x3 grids. The puzzle description: "What you see: An aerial view of a city block with structures made of various materials. One material overwhelmingly dominates the landscape, while rare materials appear in isolated buildings. What to do: Survey the block and identify the prevailing construction material. Each material is associated with a specific zoning stamp — a small blueprint mark. Stamp the permit with the appropriate mark. Grid details: The city block is 7×7. The zoning stamp is 3×3, inked in azure on a dark permit."

So we need to find the "prevailing construction material" in the 7x7 grid. That is the color that appears most frequently? Then we need to produce a 3x3 grid that is "inked in azure on a dark permit." The output examples show 3x3 grids with '.' and 'A' characters. 'A' stands for azure. The output grid seems to have 'A's in some pattern. The pattern likely corresponds to the shape of the most frequent color's arrangement? Or maybe the shape of the largest contiguous region of that color? Let's analyze training examples.

We have 5 training examples. Let's parse each.

Example 1 Input (7x7):

Row1: B . B . O . .
Row2: B B W B . B .
Row3: . . B B . R .
Row4: . . . . G . B
Row5: . Y . B . . B
Row6: . . B . R . A
Row7: . . B . O G B

Output 3x3:

A A .

So output grid has A's in positions: (1,3), (2,1),(2,2),(3,2). Let's index rows 1-3, columns 1-3.

Positions with A: (1,3), (2,1),(2,2),(3,2). That's a shape like a rotated L? Let's map coordinates: row1 col3; row2 col1, col2; row3 col2. So shape: top right, middle left, middle center, bottom center. That's like a cross shape missing top left, top center, bottom left, bottom right. Actually shape: a 3x3 with A's at positions: (1,3), (2,1),(2,2),(3,2). So pattern:

Row1: . . A
Row2: A A .
Row3: . A .

Ok.

Now we need to deduce rule: maybe we find the most frequent color in input. Let's count colors in Example 1.

Input grid:

Row1: B . B . O . . => B appears 2 times, O 1.
Row2: B B W B . B . => B 4, W 1.
Row3: . . B B . R . => B 2, R 1.
Row4: . . . . G . B => G 1, B 1.
Row5: . Y . B . . B => Y 1, B 2.
Row6: . . B . R . A => B 1, R 1, A 1.
Row7: . . B . O G B => B 2, O 1, G 1.

Count B: row1 2, row2 4, row3 2, row4 1, row5 2, row6 1, row7 2 => total B = 14? Let's sum: 2+4=6, +2=8, +1=9, +2=11, +1=12, +2=14. Yes B=14.

Count O: row1 1, row7 1 => 2.

Count W: row2 1 => 1.

Count R: row3 1, row6 1 => 2.

Count G: row4 1, row7 1 => 2.

Count Y: row5 1 => 1.

Count A: row6 1 => 1.

So B is overwhelmingly dominant. So the "prevailing construction material" is B. The output grid is azure (A) marks. So we need to produce a 3x3 grid of azure marks that correspond to something about B. Maybe we need to find the shape of the largest contiguous region of B? Let's examine B's arrangement in the 7x7 grid. Let's mark B positions:

Row1: col1, col3
Row2: col1, col2, col4, col6
Row3: col3, col4
Row4: col7
Row5: col4, col7
Row6: col3
Row7: col3, col7

So B positions: (1,1),(1,3),(2,1),(2,2),(2,4),(2,6),(3,3),(3,4),(4,7),(5,4),(5,7),(6,3),(7,3),(7,7). That's 14 positions.

Now the output 3x3 grid maybe corresponds to a 3x3 subgrid of the 7x7 that contains the most B's? Or maybe the 3x3 subgrid that has the highest density of B? Let's test: We need to find a 3x3 subgrid of the 7x7 that has the most B's. Let's compute counts for each possible 3x3 subgrid. There are 5x5 = 25 possible 3x3 subgrids. But maybe the output pattern is the shape of the B's within that subgrid? But output is 3x3 with A's at positions where B's are? Let's test: Suppose we find a 3x3 subgrid that has the most B's. Then we output a 3x3 grid with A's at positions where B's are in that subgrid, and '.' elsewhere. That would produce a pattern of A's that matches the B's in that subgrid. Let's test with Example 1.

We need to find a 3x3 subgrid that has the most B's. Let's compute B counts for each subgrid. But maybe the subgrid is the one that contains the largest contiguous cluster of B's? Let's examine B cluster: B's at (1,1),(1,3),(2,1),(2,2),(2,4),(2,6),(3,3),(3,4),(4,7),(5,4),(5,7),(6,3),(7,3),(7,7). The largest cluster might be around the top-left area: (1,1),(1,3),(2,1),(2,2),(2,4),(3,3),(3,4),(6,3),(7,3). But there are also B's at (4,7),(5,7),(7,7). So maybe the largest cluster is the top-left cluster of 8 B's? Let's count cluster sizes: cluster 1: (1,1),(1,3),(2,1),(2,2),(2,4),(3,3),(3,4),(6,3),(7,3). Wait (6,3),(7,3) are far away but maybe connected via adjacency? Let's define adjacency: 4-neighbor? Usually adjacency is orthogonal. Let's check connectivity: (1,1) adjacent to (2,1). (2,1) adjacent to (2,2). (2,2) adjacent to (1,1) and (2,1). (1,3) adjacent to (2,3) but no B at (2,3). So (1,3) is isolated from cluster? Actually (1,3) adjacent to (2,3) (empty), (1,2) (empty), (1,4) (empty), (0,3) out of bounds. So (

We need to solve a grid transformation puzzle. We have training examples with input and output. We need to deduce the rule. The puzzle description: "What you see: A contested field where many factions have deployed forces. One faction vastly outnumbers the others, whose scattered units are too few to matter. What to do: Count the forces and determine which faction holds numerical superiority. Each faction carries a unique battle standard — a small, fixed emblem. Reproduce that emblem on the strategic map. Grid details: The battlefield is a 7×7 grid. The war room emblem is a 3×3 mark in azure on a dark map."

So we have a 7x7 input grid with colors. Output is a 3x3 grid with azure (A) and black (.)? Let's examine training examples.

Example 1 Input: 7x7 grid. Output: 3x3 grid with azure and black. Let's analyze.

Example 1 Input:

Row1: B . B . O . .
Row2: B B W B . B .
Row3: . . B B . R .
Row4: . . . . G . B
Row5: . Y . B . . B
Row6: . . B . R . A
Row7: . . B . O G B

Output:
. . A
A A .
. A .

So output is 3x3 grid with azure (A) and black (.) only. So the output is a 3x3 pattern of azure and black. The puzzle says "war room emblem is a 3×3 mark in azure on a dark map." So the output is a 3x3 azure pattern on a dark map (black). So we need to produce a 3x3 azure pattern that corresponds to something derived from the input.

The description: "What you see: A contested field where many factions have deployed forces. One faction vastly outnumbers the others, whose scattered units are too few to matter. What to do: Count the forces and determine which faction holds numerical superiority. Each faction carries a unique battle standard — a small, fixed emblem. Reproduce that emblem on the strategic map."

So we need to count the number of each color in the input grid. The one with the most units is the majority. Then we need to reproduce that faction's emblem (a small fixed emblem) on the output grid. The emblem is a 3x3 pattern of azure? Wait, the output is azure pattern. But the emblem is a small fixed emblem that each faction carries. So each color has a unique emblem. The output is the emblem of the majority color. But the output is azure? Wait, the output uses azure (A) for the emblem. But the emblem is a small fixed shape that is unique to each faction. But the output uses azure for the emblem. So maybe the output is the emblem of the majority color, but drawn in azure. So the shape of the emblem is fixed for each color. So we need to know the emblem shapes for each color. But we only have examples. We need to deduce the emblem shapes from the outputs.

Let's analyze each example to deduce the majority color and the output pattern.

Example 1 Input: Let's count colors.

Colors: B, O, W, R, G, Y, A. Let's count each.

I'll parse each row:

Row1: B . B . O . . => B:2, O:1
Row2: B B W B . B . => B:4, W:1
Row3: . . B B . R . => B:2, R:1
Row4: . . . . G . B => G:1, B:1
Row5: . Y . B . . B => Y:1, B:2
Row6: . . B . R . A => B:1, R:1, A:1
Row7: . . B . O G B => B:2, O:1, G:1

Now sum:

B: row1 2 + row2 4 + row3 2 + row4 1 + row5 2 + row6 1 + row7 2 = 14
O: row1 1 + row7 1 = 2
W: row2 1 = 1
R: row3 1 + row6 1 = 2
G: row4 1 + row7 1 = 2
Y: row5 1 = 1
A: row6 1 = 1

So majority is B (blue) with 14. So the output should be the emblem of blue. The output pattern is:

. . A
A A .
. A .

So the emblem of blue is that pattern. So azure (A) marks the shape of the emblem. So the output is azure shape of the majority color's emblem.

Now Example 2 Input: Let's count.

Input rows:

Row1: . G . G X G . => G:3, X:1
Row2: . . G G . . . => G:2
Row3: A . . . . . G => A:1, G:1
Row4: G Y G W G . G => G:4, Y:1, W:1
Row5: . . W G B G G => W:1, G:3, B:1
Row6: . G G G . G . => G:4
Row7: . . . . . . G => G:1

Now sum:

G: row1 3 + row2 2 + row3 1 + row4 4 + row5 3 + row6 4 + row7 1 = 18
X: 1
A: 1
Y: 1
W: 2 (row4 1 + row5 1)
B: 1

So majority is G (green) with 18. Output pattern:

. A A
. A .
. A .

So the emblem of green is that pattern.

Example 3 Input: Let's count.

Rows:

Row1: . . R . B X G => R:1, B:1, X:1, G:1
Row2: . . R W . R . => R:2, W:1
Row3: R R R Y R . . => R:4, Y:1
Row4: . R . R O R . => R:3, O:1
Row5: R R . . R R M => R:4, M:1
Row6: . R R . R . . => R:3
Row7: X . Y R . R R => X:1, Y:1, R:3

Now sum:

R: row1 1 + row2 2 + row3 4 + row4 3 + row5 4 + row6 3 + row7 3 = 20
B: 1
X: 2 (row1 1 + row7 1)
G: 1
W: 1
Y: 2 (row3 1 + row7 1)
O: 1
M: 1

So majority is R (red) with 20. Output pattern:

. . .
A A A
. . .

So the emblem of red is that pattern.

Example 4 Input: Let's count.

Rows:

Row1: R . . R R . X => R:3, X:1
Row2: . R R . . . R => R:3
Row3: . B . . . . . => B:1
Row4: . . . . R . W => R:1, W:1
Row5: . W . . . . R => W:1, R:1
Row6: . . R B . . A => R:1, B:1, A:1
Row7: R . . R R . . => R:3

Now sum:

R: row1 3 + row2 3 + row4 1 + row5 1 + row6 1 + row7 3 = 12
X: 1
B: 1
W: 2
A: 1

So majority is R again with 12.

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A casting call where many performers appear on stage. One performer keeps showing up in scene after scene, while others make only fleeting cameos. What to do: Review the audition log and identify the performer with the most appearances. Each lead actor is known for a unique mask silhouette. Display that mask on the marquee. Grid details: The stage is 7×7. The marquee mask is 3×3, rendered in azure against a dark backdrop."

We have training examples. We need to deduce the transformation rule. Let's analyze the training examples.

Example 1:

Input grid 7x7:

Row1: B . B . O . .
Row2: B B W B . B .
Row3: . . B B . R .
Row4: . . . . G . B
Row5: . Y . B . . B
Row6: . . B . R . A
Row7: . . B . O G B

Output grid 3x3:

. . A
A A .
. A .

We need to find rule mapping input to output. The description: "identify the performer with the most appearances. Each lead actor is known for a unique mask silhouette. Display that mask on the marquee." So we need to find the color that appears most frequently in the input grid? Then output a 3x3 mask of that color? But output grid is 3x3 with azure (A) and black (.)? Wait azure is A. The output grid has A's and .s. So maybe we need to output a 3x3 mask of the most frequent color, but the mask shape is unique to each color? The description: "Each lead actor is known for a unique mask silhouette." So each color has a unique 3x3 pattern? The output shows a pattern of A's and .s. So maybe the pattern is the silhouette of the most frequent color. But we need to deduce the pattern for each color. Let's analyze Example 1: Input has many colors: B, O, W, R, G, Y, A. We need to find the most frequent color. Let's count.

Input grid:

Row1: B . B . O . . => B appears 2 times, O 1
Row2: B B W B . B . => B 4, W 1
Row3: . . B B . R . => B 2, R 1
Row4: . . . . G . B => G 1, B 1
Row5: . Y . B . . B => Y 1, B 2
Row6: . . B . R . A => B 1, R 1, A 1
Row7: . . B . O G B => B 2, O 1, G 1

Let's sum B: Row1 2, Row2 4, Row3 2, Row4 1, Row5 2, Row6 1, Row7 2 => total B = 14? Let's sum: 2+4=6, +2=8, +1=9, +2=11, +1=12, +2=14. Yes B=14.

O: Row1 1, Row7 1 => 2
W: Row2 1 => 1
R: Row3 1, Row6 1 => 2
G: Row4 1, Row7 1 => 2
Y: Row5 1 => 1
A: Row6 1 => 1

So B is most frequent. Output grid is 3x3 with A's and .s. But B is most frequent, not A. So maybe the output is the silhouette of the most frequent color, but the silhouette is represented in azure (A). So we output the shape of B's positions? But the output grid is 3x3, not 7x7. So maybe we need to find the 3x3 subgrid that contains the most B's? Or maybe we need to find the 3x3 mask that matches the shape of the most frequent color's pattern? Let's analyze the output pattern: . . A / A A . / . A . . Wait output is 3x3:

Row1: . . A
Row2: A A .
Row3: . A .

Let's write coordinates (row, col) 1-indexed:

(1,3) A
(2,1) A
(2,2) A
(3,2) A

So shape: a cross shape? Actually it's like a T shape rotated? Let's visualize:

Row1: ..A
Row2: AA.
Row3: .A.

This shape is like a 3x3 pattern with 4 A's. Let's see if this matches the shape of B's positions in the input? But B's positions are many across the grid. But maybe we need to find the 3x3 subgrid that has the most B's? Let's check all 3x3 subgrids of the 7x7 input. There are 5x5 = 25 subgrids. For each subgrid, count B's. The subgrid with the most B's might be the one that matches the output pattern? But the output pattern is not B's but A's. But maybe we output the silhouette of the most frequent color but in azure. So we need to find the 3x3 subgrid that has the most B's, then output that subgrid's pattern but with B replaced by A? Let's test.

We need to find the 3x3 subgrid with the most B's. Let's compute quickly. But maybe the output pattern is the shape of B's in that subgrid. Let's compute B counts for each 3x3 subgrid. We'll need to examine the input grid.

Let's label the grid coordinates:

Row1: 1: B, 2: ., 3: B, 4: ., 5: O, 6: ., 7: .
Row2: 1: B, 2: B, 3: W, 4: B, 5: ., 6: B, 7: .
Row3: 1: ., 2: ., 3: B, 4: B, 5: ., 6: R, 7: .
Row4: 1: ., 2: ., 3: ., 4: ., 5: G, 6: ., 7: B
Row5: 1: ., 2: Y, 3: ., 4: B, 5: ., 6: ., 7: B
Row6: 1: ., 2: ., 3: B, 4: ., 5: R, 6: ., 7: A
Row7: 1: ., 2: ., 3: B, 4: ., 5: O, 6: G, 7: B

We need to find 3x3 subgrid with most B's. Let's compute B counts for each subgrid starting at (i,j) where i=1..5, j=1..5.

We'll compute quickly.

Define B positions: (1,1),(1,3),(2,1),(2,2),(2,4),(2,6),(3,3),(3,4),(4,7),(5,4),(5,7),(6,3),(7,3),(7,7). That's 14 B's.

Now for each subgrid, we count B's.

Subgrid (1,1) rows 1-3, cols 1-3:

Rows 1-3, cols 1-3:

Row1: B . B
Row2: B B W
Row3: . . B

B's: (1,1),(1,3),(2,1),(2,2),(3,3) => 5 B's.

Subgrid (1,2) rows 1-3, cols 2-4:

Row1: . B .
Row2: B W B
Row3: . . B

B's: (1,3),(2,1? Wait col2? Actually (2,2) is B? Wait row2 col2 is B, but col2 is part of subgrid? Yes subgrid columns 2-4 includes

We need to solve a grid transformation puzzle. The description: "What you see: A warrior carries two shields stacked one behind the other — the front shield is forged from green iron, the rear from blue steel. Each shield has gaps where the metal was never filled in, leaving dark empty spaces. What to do: An archer fires arrows at the paired shields. Where both shields have holes — where neither green iron nor blue steel stands guard — the arrow passes clean through and leaves a red wound on the wall behind. Wherever at least one shield holds firm, the arrow is deflected and the wall stays unmarked. Grid details: The two shields sit one atop the other in the input, each a square slab four units across. The wall behind them, revealed in the output, is the same size as a single shield, dark except where it bleeds red."

So we have two shields stacked: front shield is green, rear shield is blue. Each shield is a 4x4 grid? The input grid likely contains both shields stacked vertically? The output grid is a 4x4 grid representing the wall behind them, with red where both shields have holes (i.e., both are empty at that position). The input grid likely contains a 8x4 grid? Actually, the input grid might be 8 rows by 4 columns: first 4 rows are the front shield (green), next 4 rows are the rear shield (blue). But the example input shows 9 rows? Let's examine the training example.

Example 1 Input:
```
. G G .
. G . G
. . G .
G G G G
B B B B
B B . .
B B . .
. B B .
```
Wait, that's 9 rows? Let's count: Row1: ". G G .", Row2: ". G . G", Row3: ". . G .", Row4: "G G G G", Row5: "B B B B", Row6: "B B . .", Row7: "B B . .", Row8: ". B B .". That's 8 rows. Actually, I miscounted: Let's list them:

1. ". G G ."
2. ". G . G"
3. ". . G ."
4. "G G G G"
5. "B B B B"
6. "B B . ."
7. "B B . ."
8. ". B B ."

Yes, 8 rows. So the input grid is 8 rows by 4 columns. The first 4 rows are the front shield (green). The next 4 rows are the rear shield (blue). But the first 4 rows contain both green and maybe some black? Wait, the first 4 rows contain G and . only? Let's check: Row1: ". G G .": has '.' and 'G'. Row2: ". G . G": '.' 'G' '.' 'G'. Row3: ". . G .": '.' '.' 'G' '.'. Row4: "G G G G": all G. So yes, first 4 rows are green shield with holes ('.').

Rows 5-8: "B B B B", "B B . .", "B B . .", ". B B .": these contain B and '.' only. So second shield is blue with holes.

So the input grid is 8x4: top 4 rows are green shield, bottom 4 rows are blue shield. The output grid is 4x4: "wall behind them" with red where both shields have holes. The output grid in example 1 is:

```
. . . .
. . R .
. . . R
. . . .
```

Wait, that's 4 rows by 4 columns. Let's check: Row1: ". . . .", Row2: ". . R .", Row3: ". . . R", Row4: ". . . .". So indeed 4x4.

So the rule: For each cell position (i,j) in the 4x4 grid, if the corresponding cell in the green shield (top 4 rows) is '.' (hole) AND the corresponding cell in the blue shield (bottom 4 rows) is '.' (hole), then output 'R' at that position. Else output '.' (black). That matches the description: arrow passes through only if both shields have holes; else arrow deflected.

But we need to confirm that the output grid uses '.' for black (unmarked). Yes, the output uses '.' for black. So the rule is: For each position (row, col) in 4x4, if both input rows (top 4 rows and bottom 4 rows) have '.' at that position, output 'R', else '.'.

But we need to confirm that the input grid always has 8 rows by 4 columns. The test input is:

```
. G . G
G G G .
. . . G
G G G .
. . B B
. . B B
. B . .
B B . .
```

Let's count rows: Row1: ". G . G", Row2: "G G G .", Row3: ". . . G", Row4: "G G G .", Row5: ". . B B", Row6: ". . B B", Row7: ". B . .", Row8: "B B . .". So 8 rows by 4 columns. So indeed the input is 8x4. The first 4 rows are green shield, next 4 rows are blue shield.

We need to produce a 4x4 output grid. Let's compute.

We need to parse the input grid. Let's write them as arrays:

Green shield (rows 1-4):
Row1: ". G . G"
Row2: "G G G ."
Row3: ". . . G"
Row4: "G G G ."

Blue shield (rows 5-8):
Row5: ". . B B"
Row6: ". . B B"
Row7: ". B . ."
Row8: "B B . ."

We need to check each column and row.

Let's index rows 1-4 for green, 5-8 for blue. For each position (r,c) where r=1..4, c=1..4, we check green[r][c] and blue[r+4][c]. If both are '.' then output 'R', else '.'.

Let's write them in a table:

We'll create a 4x4 grid of output.

Let's label columns 1-4.

Green rows:

Row1: col1 '.', col2 'G', col3 '.', col4 'G'
Row2: col1 'G', col2 'G', col3 'G', col4 '.'
Row3: col1 '.', col2 '.', col3 '.', col4 'G'
Row4: col1 'G', col2 'G', col3 'G', col4 '.'

Blue rows:

Row5: col1 '.', col2 '.', col3 'B', col4 'B'
Row6: col1 '.', col2 '.', col3 'B', col4 'B'
Row7: col1 '.', col2 'B', col3 '.', col4 '.'
Row8: col1 'B', col2 'B', col3 '.', col4 '.'

Now we need to pair each green row with the corresponding blue row: row1 with row5, row2 with row6, row3 with row7, row4 with row8.

So for each position

We need to solve a grid transformation puzzle. The description: "What you see: A specimen slide divided into two layered membranes—one stained green, one stained blue—each with gaps in their coverage. What to do: Overlay the two membranes and find where both leave the tissue exposed. The dye penetrates only through shared openings, marking those sites red. Grid details: The input is 4 columns by 8 rows, two 4×4 membrane layers stacked. The output is a single 4×4 tissue sample. Background is unstained black."

We have training example 1: Input grid 4 columns by 8 rows? Let's examine. Example 1 Input:

```
. G G .
. G . G
. . G .
G G G G
B B B B
B B . .
B B . .
. B B .
```

That's 8 rows, each row has 4 columns. So yes 4x8 grid. The first 4 rows correspond to green membrane? The next 4 rows correspond to blue membrane? The description says two 4x4 membrane layers stacked. So the first 4 rows are green membrane, next 4 rows are blue membrane. The output is a single 4x4 tissue sample. The rule: overlay the two membranes and find where both leave the tissue exposed. The dye penetrates only through shared openings, marking those sites red. So we need to find cells where both membranes have a gap (i.e., '.' maybe indicates gap). But the description says "background is unstained black." The output grid uses '.' for black. The output example:

```
. . . .
. . R .
. . . R
. . . .
```

Let's analyze the input to confirm.

Input first 4 rows (green membrane):

Row1: . G G .
Row2: . G . G
Row3: . . G .
Row4: G G G G

So green membrane has '.' at positions: (1,1), (1,4), (2,1), (2,3), (3,1), (3,2), (3,4), (4,1?) Wait row4 has G G G G, so no '.' in row4. So green gaps at positions: (row, col) coordinates 1-indexed: (1,1), (1,4), (2,1), (2,3), (3,1), (3,2), (3,4). That's 7 gaps.

Blue membrane (next 4 rows):

Row5: B B B B
Row6: B B . .
Row7: B B . .
Row8: . B B .

So blue gaps at positions: (row5? Actually row5 is first row of blue membrane, but we need to map to 4x4 grid coordinates. So row5 corresponds to row1 of blue membrane, row6 to row2, row7 to row3, row8 to row4. So blue gaps at: row6 col3, row6 col4, row7 col3, row7 col4, row8 col1, row8 col4. So positions: (1,3), (1,4), (2,3), (2,4), (3,1), (3,4). Wait careful: row6 is second row of blue membrane: B B . . => gaps at col3, col4. Row7: B B . . => gaps at col3, col4. Row8: . B B . => gaps at col1, col4. So yes.

Now overlay: We need to find positions where both membranes have a gap. That is intersection of green gaps and blue gaps. Let's list green gaps: (1,1), (1,4), (2,1), (2,3), (3,1), (3,2), (3,4). Blue gaps: (1,3), (1,4), (2,3), (2,4), (3,1), (3,4). Intersection: (1,4), (2,3), (3,1), (3,4). That's 4 positions. The output grid shows red at positions: row2 col3? Wait output grid:

```
. . . .
. . R .
. . . R
. . . .
```

Let's map coordinates: row1: all '.'; row2: '.' '.' 'R' '.' => red at (2,3). row3: '.' '.' '.' 'R' => red at (3,4). row4: all '.'.

But we also expected red at (1,4) and (3,1). But output shows only two red cells. So maybe the rule is different: maybe we overlay the two membranes and find where both leave the tissue exposed, but the dye penetrates only through shared openings, marking those sites red. But maybe the output is not the intersection but something else. Let's analyze again.

Maybe the output grid is not the intersection but the union? But union would be all positions where either membrane has a gap. That would be many positions. But output only has two red cells. So maybe the output grid is the intersection but only for positions where the green membrane has a gap and the blue membrane has a gap, but also maybe the output grid is rotated or something? Let's examine the positions of red in output: (2,3) and (3,4). These correspond to intersection positions (2,3) and (3,4). So output includes only two of the four intersection positions. Which ones? (1,4) and (3,1) are missing. Why? Let's examine the input: maybe the membranes are stacked, but the output is a 4x4 tissue sample. The input is 4x8 grid: first 4 rows are green membrane, next 4 rows are blue membrane. The output is 4x4. So we overlay the two membranes: we need to combine them into a single 4x4 grid. But maybe the overlay is done by aligning the membranes such that the top of the blue membrane is aligned with the bottom of the green membrane? But the input is 4x8, so maybe the two membranes are stacked vertically: the green membrane is on top, the blue membrane is below. But the output is a single 4x4 tissue sample. So we need to overlay them: maybe we overlay them by aligning them such that the top of the blue membrane is aligned with the bottom of the green membrane? But that would produce a 4x4 grid where each cell is the result of combining the two cells from the two membranes at the same position. But the input is 4x8, so we can pair each row of green with each row of blue? But there are 4 rows each, so we can pair row1 of green with

We need to solve a grid transformation puzzle. The description: "You are solving a grid transformation puzzle. You are given a metaphorical description of the transformation, training examples, and a test input grid.

Color key: .=black B=blue R=red G=green Y=yellow X=grey M=magenta O=orange A=azure W=maroon

## Metaphorical Description

What you see: A telescope view showing two overlapping nebula layers, one glowing green and one blue, each with dark gaps in their gas clouds.
What to do: Where both nebulae have voids at the same position, the background red dwarf's light is visible. Mark those sightlines red in the observation chart.
Grid details: Input is 4 wide by 8 tall, two 4×4 nebula maps. Output is a 4×4 stellar visibility chart. Background is empty space (black).

Before predicting the output, perform a Conceptual Digestion:
1. Identify the CAST: What roles do different grid elements play?
2. Identify the AFFORDANCES: What can each element do or have done to it?
3. Identify the TRANSFORMATION RULE: What is the precise rule that maps input to output?

Then apply the rule to the test input to predict the output grid.

## Training Examples

Example 1:
Input:
. G G .
. G . G
. . G .
G G G G
B B B B
B B . .
B B . .
. B B .
Output:
. . . .
. . R .
.. etc.

Example 2, Example 3.

Test Input:
. G . G
G G G .
. . . G
G G G .
. . B B
. . B B
. B . .
B B . .

We need to produce output grid 4x4.

We need to deduce transformation rule from training examples.

Let's parse training examples carefully.

We have input grids of size 4x8? Wait: The description says Input is 4 wide by 8 tall, two 4×4 nebula maps. So input grid is 4 columns by 8 rows. The first 4 rows correspond to green nebula map? The next 4 rows correspond to blue nebula map? Let's examine Example 1 input:

Example 1 Input:
```
. G G .
. G . G
. . G .
G G G G
B B B B
B B . .
B B . .
. B B .
```
Let's count rows: 8 rows. Each row has 4 characters. So yes 4x8 grid.

We can think of first 4 rows as green map, next 4 rows as blue map. But we need to confirm.

Let's label rows 0-7. Row 0: ". G G ."
Row 1: ". G . G"
Row 2: ". . G ."
Row 3: "G G G G"
Row 4: "B B B B"
Row 5: "B B . ."
Row 6: "B B . ."
Row 7: ". B B ."

Now output grid is 4x4:

```
. . . .
. . R .
. . . R
. . . .
```

So output has red cells at positions (1,2) and (2,3) (0-indexed). Let's analyze.

The metaphor: "two overlapping nebula layers, one glowing green and one blue, each with dark gaps in their gas clouds. Where both nebulae have voids at the same position, the background red dwarf's light is visible. Mark those sightlines red in the observation chart."

So we have two maps: green and blue. Each has voids (dark gaps). Where both have voids at same position, we mark red. So we need to find positions where both maps have '.'? Wait: The maps are 4x4 each. The input grid is 4x8: first 4 rows are green map, next 4 rows are blue map. The cells in each map can be '.' (empty) or 'G' or 'B'? Actually the green map uses 'G' for gas? The blue map uses 'B' for gas? The voids are '.'? But the input uses '.' for empty, 'G' for green gas, 'B' for blue gas. So the voids are '.'.

Thus we need to find positions where both maps have '.' at same coordinates. Then output grid should have 'R' at those positions. All other positions are '.' (black). That seems plausible.

Let's test with Example 1.

Green map (rows 0-3):
Row0: . G G .
Row1: . G . G
Row2: . . G .
Row3: G G G G

Blue map (rows 4-7):
Row4: B B B B
Row5: B B . .
Row6: B B . .
Row7: . B B .

Now we need to overlay them: For each position (col, row) 0-3, check if green map has '.' and blue map has '.' at same coordinates. Let's compute.

We'll create 4x4 grid coordinates: row 0-3, col 0-3.

Green map:
- (0,0) '.'; (1,0) 'G'; (2,0) 'G'; (3,0) '.'
- (0,1) '.'; (1,1) 'G'; (2,1) '.'; (3,1) 'G'
- (0,2) '.'; (1,2) '.'; (2,2) 'G'; (3,2) '.'
- (0,3) 'G'; (1,3) 'G'; (2,3) 'G'; (3,3) 'G'

Blue map:
- (0,0) 'B'; (1,0) 'B'; (2,0) 'B'; (3,0) 'B'
- (0,1) 'B'; (1,1) 'B'; (2,1) '.'; (3,1) '.'
- (0,2) 'B'; (1,2) 'B'; (2,2) '.'; (3,2) '.'
- (0,3) '.'; (1,3) 'B'; (2,3) 'B'; (3,3) '.'

Now find positions where both are '.':

- (0,0): green '.' but blue 'B' -> no
- (1,0): green 'G' -> no
- (2,0): green 'G' -> no
- (3,0): green '.' but blue 'B' -> no
- (0,1): green '.' but blue 'B' -> no
- (1,1): green 'G' -> no
- (2,1): green '.' and blue '.' -> yes -> (2,1) should be 'R'
- (3,1): green 'G' -> no
- (0,2): green '.' but blue 'B' -> no
- (1,2): green '.' and blue 'B' -> no
- (2,2): green 'G' -> no
- (3,2): green '.' and blue '.' -> yes -> (3,2) should be 'R'
- (0,3): green 'G' -> no
- (1,3): green 'G' -> no
- (2,3): green 'G' -> no
- (3,3): green 'G' -> no

Thus we expect 'R' at (2,1) and (3,2). Let's check output: Output grid:

Row0: . . . .
Row1: . . R .
Row2: . . . R
Row3: . . . .

Indices: row0 col0-3 all '.'; row1 col2 'R'; row2 col3 'R'; row3 all '.'.

Matches our computed positions: (2,1) an

We need to parse the problem. The puzzle: "grid transformation puzzle" with metaphorical description. We have training examples. We need to deduce transformation rule. Input grid: 4 wide by 8 tall, two 4×4 masks. Output is a 4×4 wafer surface. Background is unetched silicon (black). The description: "What you see: A fabrication stack showing two photolithography masks, one green-tinted and one blue-tinted, each with opaque and transparent zones. What to do: Align the masks. Where both are transparent at the same cell, the laser etches through and marks the wafer red. All other positions remain unetched."

So we have two masks: green mask and blue mask. Each mask is 4x4. The input grid is 4 wide by 8 tall, so presumably the first 4 rows correspond to green mask, next 4 rows correspond to blue mask. The output is 4x4 wafer surface. The rule: For each cell, if both masks have transparent (i.e., not opaque) at that cell, then output is red. Else output remains black (unetched). Transparent vs opaque: In the input, we have characters: '.' (black), 'G' (green), 'B' (blue). But we need to interpret which are transparent and which are opaque. The description: "two photolithography masks, one green-tinted and one blue-tinted, each with opaque and transparent zones." So each mask has transparent and opaque zones. The input uses 'G' and 'B' to represent the mask color? Wait: The input grid uses '.' for black, 'G' for green, 'B' for blue. But we need to interpret which cells are transparent or opaque. In the example, we need to deduce mapping.

Let's analyze Example 1.

Example 1 Input:

```
. G G .
. G . G
. . G .
G G G G
B B B B
B B . .
B B . .
. B B .
```

We need to parse: 4 wide by 8 tall. So first 4 rows (rows 0-3) are green mask. Next 4 rows (rows 4-7) are blue mask.

Let's write them:

Green mask (rows 0-3):
Row0: . G G .
Row1: . G . G
Row2: . . G .
Row3: G G G G

Blue mask (rows 4-7):
Row4: B B B B
Row5: B B . .
Row6: B B . .
Row7: . B B .

Now output is 4x4 wafer surface:

```
. . . .
. . R .
. . . R
. . . .
```

We need to see how this output arises.

We need to interpret transparent vs opaque. Usually in photolithography, transparent zones allow light to pass through, opaque zones block. The mask color indicates the mask type: green mask or blue mask. But the color might not indicate transparency. The input uses '.' for black (maybe representing transparent? Or maybe black is background? Wait: The color key: .=black B=blue R=red G=green Y=yellow X=grey M=magenta O=orange A=azure W=maroon. So '.' is black. But in the input, '.' appears in both masks. But the description says "two photolithography masks, one green-tinted and one blue-tinted, each with opaque and transparent zones." So each mask is tinted green or blue. So the mask color indicates the mask type. Transparent zones might be represented by '.'? But '.' is black, not green or blue. But maybe the mask color indicates the color of the mask, but the mask's transparent zones are represented by '.'? But then how to differentiate between transparent and opaque? The mask color might be used to indicate the mask type, but the mask's transparent zones might be indicated by '.'? But the input uses 'G' and 'B' to represent the mask color. But we need to differentiate transparent vs opaque. Perhaps the mask color indicates the mask type, but the mask's transparent zones are indicated by '.'? But then the mask's opaque zones would be indicated by 'G' or 'B'? But that would mean that 'G' and 'B' represent opaque zones. But the description says "two photolithography masks, one green-tinted and one blue-tinted, each with opaque and transparent zones." So the mask color is the tint, but the mask's transparent zones might be indicated by '.'? But the input uses '.' for black, which might represent transparent? But black is not transparent. But maybe the input uses '.' to represent transparent (i.e., no color). But the color key says '.' is black. But maybe the color key is for output only? But the input uses '.' as black. But the input might use '.' to represent transparent (i.e., no color). But the color key might be for output only. But the problem statement says "Color key: .=black B=blue R=red G=green Y=yellow X=grey M=magenta O=orange A=azure W=maroon". That might apply to both input and output. But the input uses '.' for black. But the mask color is green or blue. So maybe the mask's transparent zones are represented by '.' (black). But that would mean that the mask's opaque zones are represented by 'G' or 'B' (colored). But that seems plausible: The mask is tinted green or blue, but the transparent zones are black (no color). But the mask's opaque zones are colored (green or blue). But that seems contradictory: In a mask, the opaque zones are usually black (opaque) and transparent zones are white. But here the mask is tinted green or blue, so maybe the mask's transparent zones are colored (green or blue) and opaque zones are black. But the input us

We need to solve a grid transformation puzzle. The description: "What you see: A threshold woven with two layers of magical protection, one shimmering green and one blue, each with unprotected gaps. What to do: Where both enchantments are absent at the same spot, infernal red flame breaks through the threshold. Mark those breaches red. Grid details: Input is 4 columns by 8 rows, two 4×4 ward layers. Output is a 4×4 threshold map. Background is sealed stone (black)."

We have training example 1: Input grid 4 columns by 8 rows? Let's examine. Example 1 Input:

```
. G G .
. G . G
. . G .
G G G G
B B B B
B B . .
B B . .
. B B .
```

That's 8 rows, each row has 4 columns. So yes 4x8 grid. Output:

```
. . . .
. . R .
. . . R
. . . .
```

So output is 4x4 grid. The rule: Where both enchantments are absent at the same spot, mark red. The two enchantments are green and blue layers. The input grid has two layers: first 4 rows are green layer? Actually first 4 rows: rows 1-4: . G G ., . G . G, . . G ., G G G G. That seems to be green layer. Next 4 rows: B B B B, B B . ., B B . ., . B B . . That seems to be blue layer. So each layer is 4x4. The output is 4x4 threshold map. The rule: For each cell (i,j) in 4x4, if both layers have no protection at that spot (i.e., both are '.'?), then mark red. But the output shows red at positions (2,3) and (3,4) (1-indexed). Let's check: In input, green layer at (2,3) is '.'? Let's index rows 1-4, columns 1-4. Green layer:

Row1: . G G . => col1 '.', col2 'G', col3 'G', col4 '.'
Row2: . G . G => col1 '.', col2 'G', col3 '.', col4 'G'
Row3: . . G . => col1 '.', col2 '.', col3 'G', col4 '.'
Row4: G G G G => col1 'G', col2 'G', col3 'G', col4 'G'

Blue layer rows 5-8:

Row5: B B B B => col1 'B', col2 'B', col3 'B', col4 'B'
Row6: B B . . => col1 'B', col2 'B', col3 '.', col4 '.'
Row7: B B . . => col1 'B', col2 'B', col3 '.', col4 '.'
Row8: . B B . => col1 '.', col2 'B', col3 'B', col4 '.'

Now, for each cell, we check if both layers are '.'? Let's compute:

Cell (1,1): green '.'; blue 'B' => not both '.' => no red
Cell (1,2): green 'G'; blue 'B' => no
Cell (1,3): green 'G'; blue 'B' => no
Cell (1,4): green '.'; blue 'B' => no

Cell (2,1): green '.'; blue 'B' => no
Cell (2,2): green 'G'; blue 'B' => no
Cell (2,3): green '.'; blue '.' => both '.' => red
Cell (2,4): green 'G'; blue '.' => no

Cell (3,1): green '.'; blue 'B' => no
Cell (3,2): green '.'; blue 'B' => no
Cell (3,3): green 'G'; blue '.' => no
Cell (3,4): green '.'; blue '.' => both '.' => red

Cell (4,1): green 'G'; blue '.' => no
Cell (4,2): green 'G'; blue 'B' => no
Cell (4,3): green 'G'; blue '.' => no
Cell (4,4): green 'G'; blue '.' => no

Thus red at (2,3) and (3,4). Output shows red at those positions. Yes.

So rule: For each cell in 4x4, if both layers have '.' (no protection), output 'R', else output '.' (black). That matches description: "Where both enchantments are absent at the same spot, infernal red flame breaks through the threshold. Mark those breaches red." So output is black except red at cells where both layers are '.'.

Now we need to apply to test input.

Test Input:

```
. G . G
G G G .
. . . G
G G G .
. . B B
. . B B
. B . .
B B . .
```

Let's parse. 8 rows, 4 columns each.

Rows 1-4: green layer.

Row1: . G . G
Row2: G G G .
Row3: . . . G
Row4: G G G .

Rows 5-8: blue layer.

Row5: . . B B
Row6: . . B B
Row7: . B . .
Row8: B B . .

We need to produce 4x4 output: for each cell, if both green and blue are '.' then 'R', else '.'.

Let's compute.

First, create arrays.

Green layer (rows 1-4):

Row1: col1 '.', col2 'G', col3 '.', col4 'G'
Row2: col1 'G', col2 'G', col3 'G', col4 '.'
Row3: col1 '.', col2 '.', col3 '.', col4 'G'
Row4: col1 'G', col2 'G', col3 'G', col4 '.'

Blue layer (rows 5-8):

Row5: col1 '.', col2 '.', col3 'B', col4 'B'
Row6: col1 '.', col2 '.', col3 'B', col4 'B'
Row7: col1 '.', col2 'B', col3 '.', col4 '.'
Row8: col1 'B', col2 'B', col3 '.', col4 '.'

Now compute for each cell (i,j):

We'll index rows 1-4, columns 1-4.

Cell (1,1): green '.'; blue '.' => both '.' => red
Cell (1,2): green 'G'; blue '.' => not both '.' => black
Cell (1,3): green '.'; blue 'B' => not both '.' => black
Cell (1,4): green 'G'; blue 'B' => not both '.' => black

Cell (2,1): green 'G'; blue '.' => black
Cell (2,2): green 'G'; blue '.' => black
Cell (2,3): green 'G'; blue 'B' => black
Cell (2,4): green '.'; blue 'B' => black

Cell (3,1): green '.'; blue '.' => red
Cell (3,2): green '.'; blue 'B' => black
Cell (3,3): green '.'; blue '.' => red
Cell (3,4): green 'G'; blue '.' => black

Cell (4,1): green 'G'; blue 'B' => black
Cell (4,2): green 'G'; blue 'B' => black
Cell (4,3): green 'G'; blue '.' => black
Cell (4,4): green '.'; blue '.' => red

Thus red at positions: (1,1), (3,1), (3,3), (4,4). Let's double-check.

Wait, check (3,3): green '.'; blue '.'? Let's conf

We need to solve a grid transformation puzzle. The description: "What you see: A rehearsal floor divided into two practice sessions viewed from above, one troupe in green and one in blue, each occupying certain tiles. What to do: Compare both formations. Where neither troupe occupies a tile, the choreographer marks it with a red rose for the final number. Grid details: Input is 4 wide by 8 tall, two 4×4 floor plans. Output is a 4×4 rose placement map. Background is bare floor (black)."

So we have an input grid of 4 columns by 8 rows. The first 4 rows correspond to the green troupe's floor plan? Actually the description says "two 4×4 floor plans" meaning the input grid is 4 wide by 8 tall, representing two 4x4 grids stacked vertically: top 4 rows for green, bottom 4 rows for blue. The output is a 4x4 grid of red roses placed where neither troupe occupies a tile. So we need to compute the intersection of the two sets? Wait: "Where neither troupe occupies a tile, the choreographer marks it with a red rose for the final number." That means we need to find cells that are empty (.) in both the green and blue floor plans. Those cells become red (R) in the output. All other cells remain black (.)? But the output examples show only '.' and 'R' cells. Let's examine training examples to confirm.

Example 1 Input:

```
. G G .
. G . G
. . G .
G G G G
B B B B
B B . .
B B . .
. B B .
```

Let's parse: 8 rows, 4 columns each. Top 4 rows (rows 0-3) are green plan. Bottom 4 rows (rows 4-7) are blue plan.

Let's label coordinates: row 0-3 for green, row 4-7 for blue. Each row has 4 columns.

Green plan:

Row0: . G G .
Row1: . G . G
Row2: . . G .
Row3: G G G G

Blue plan:

Row4: B B B B
Row5: B B . .
Row6: B B . .
Row7: . B B .

Now we need to produce output 4x4 grid of red roses where neither troupe occupies a tile. That means we need to find cells that are '.' in both green and blue at the same coordinates (i.e., same row and column). Let's compute.

We need to align the two 4x4 grids: top 4 rows vs bottom 4 rows. So we compare row0 of green with row0 of blue? Wait, the bottom 4 rows are rows 4-7. So row4 of input corresponds to row0 of blue plan. So we need to map row index: row i of green (0-3) corresponds to row i of blue (4-7). So we compare each cell at (i,j) for i=0..3, j=0..3.

Let's compute:

Green grid G[i][j], Blue grid B[i][j] (i=0..3). We'll compute.

Row0: G[0] = . G G .
Row0 of blue: B[0] = B B B B

Positions:
- (0,0): G '.' ; B 'B' -> not both '.' -> no rose.
- (0,1): G 'G'; B 'B' -> no.
- (0,2): G 'G'; B 'B' -> no.
- (0,3): G '.' ; B 'B' -> no.

Row1: G[1] = . G . G
Blue row1: B[1] = B B . .

Positions:
- (1,0): G '.' ; B 'B' -> no.
- (1,1): G 'G'; B 'B' -> no.
- (1,2): G '.' ; B '.' -> both '.' -> rose.
- (1,3): G 'G'; B '.' -> no.

Row2: G[2] = . . G .
Blue row2: B[2] = B B . .

Positions:
- (2,0): G '.' ; B 'B' -> no.
- (2,1): G '.' ; B 'B' -> no.
- (2,2): G 'G'; B '.' -> no.
- (2,3): G '.' ; B '.' -> rose.

Row3: G[3] = G G G G
Blue row3: B[3] = . B B .

Positions:
- (3,0): G 'G'; B '.' -> no.
- (3,1): G 'G'; B 'B' -> no.
- (3,2): G 'G'; B 'B' -> no.
- (3,3): G 'G'; B '.' -> no.

So we have roses at (1,2) and (2,3). Let's check output example 1:

Output:
```
. . . .
. . R .
. . . R
. . . .
```

Indices: row0: . . . . ; row1: . . R . ; row2: . . . R ; row3: . . . .

Matches our computed positions: (1,2) and (2,3). Good.

So rule: For each cell (i,j) in 4x4 grid, if both green and blue have '.' at that cell, output 'R', else '.'.

Now Example 2:

Input:
```
G G G G
. G G .
. . G G
G . . .
. . . B
. . . B
. B . .
B . . B
```

Let's parse: top 4 rows (rows 0-3) are green plan:

Row0: G G G G
Row1: . G G .
Row2: . . G G
Row3: G . . .

Bottom 4 rows (rows 4-7) are blue plan:

Row4: . . . B
Row5: . . . B
Row6: . B . .
Row7: B . . B

Now compute positions where both '.'.

Let's compute:

Row0: G[0] = G G G G
Blue row0: B[0] = . . . B

Positions:
- (0,0): G 'G'; B '.' -> no.
- (0,1): G 'G'; B '.' -> no.
- (0,2): G 'G'; B '.' -> no.
- (0,3): G 'G'; B 'B' -> no.

Row1: G[1] = . G G .
Blue row1: B[1] = . . . B

Positions:
- (1,0): G '.' ; B '.' -> rose.
- (1,1): G 'G'; B '.' -> no.
- (1,2): G 'G'; B '.' -> no.
- (1,3): G '.' ; B 'B' -> no.

Row2: G[2] = . . G G
Blue row2: B[2] = . B . .

Positions:
- (2,0): G '.' ; B '.' -> rose.
- (2,1): G '.' ; B 'B' -> no.
- (2,2): G 'G'; B '.' -> no.
- (2,3): G 'G'; B '.' -> no.

Row3: G[3] = G . . .
Blue row3: B[3] = B . . B

Positions:
- (3,0): G 'G'; B 'B' -> no.
- (3,1): G '.' ; B '.' -> rose.
- (3,2): G '.' ; B '.' -> rose.
- (3,3): G '.' ; B 'B' -> no.

So we have roses at (1,0), (2,0), (3,1), (3,2). Let's check output example 2:

Output:
```
. . . .
R . . .
R . . .
. R R .
```

Indices: row0: . . . . ; row1: R . . . ; row2: R . . . ; row3: . R R .

Matches our computed positions: (1,0), (2,0), (3,1), (3,2). Good.

Thus rule confirmed.

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A geological cross-section showing two rock layers, one green-mineralized and one blue, each with fissures and solid sections. What to do: Where fractures in both strata align at the same position, magma erupts through, marking those surface vents red. Grid details: Input is 4 columns by 8 rows, two 4×4 rock strata. Output is a 4×4 surface eruption map. Background is solid crust (black)."

We have training examples. Example 1: Input grid 4x8? Let's examine. Provided Input:

```
. G G .
. G . G
. . G .
G G G G
B B B B
B B . .
B B . .
. B B .
```

That's 8 rows, each row has 4 columns. So yes 4x8. Output:

```
. . . .
. . R .
. . . R
. . . .
```

So output is 4x4. The rule: Where fractures in both strata align at the same position, magma erupts through, marking those surface vents red. So we need to find positions where both strata have a fracture (i.e., a '.' maybe?) at the same column and row? But the strata are two 4x4 layers stacked vertically: top 4 rows are green layer, bottom 4 rows are blue layer. The output is 4x4 surface eruption map: each cell corresponds to a column and row of the strata? But the output is 4x4, same as each layer. So we need to map each column and row of the strata to a cell in output. The rule: Where fractures in both strata align at the same position, magma erupts through, marking those surface vents red. So we need to check for each column and row (i.e., each cell in the 4x4 grid) if both the green layer and blue layer have a fracture at that position. But the strata are 4x4 each. The green layer occupies rows 0-3, columns 0-3. The blue layer occupies rows 4-7, columns 0-3. So we need to check for each column j (0-3) and row i (0-3) if the cell at (i,j) in the green layer is '.' (fracture) and the cell at (i+4,j) in the blue layer is '.' (fracture). If both are '.' then output cell (i,j) is 'R' (red). Else output cell (i,j) is '.' (black). That seems plausible.

Let's test with Example 1. We'll parse the input:

Row 0: ". G G ."
Row 1: ". G . G"
Row 2: ". . G ."
Row 3: "G G G G"
Row 4: "B B B B"
Row 5: "B B . ."
Row 6: "B B . ."
Row 7: ". B B ."

Let's index rows 0-7, columns 0-3.

Green layer rows 0-3:

- (0,0) = '.'
- (0,1) = 'G'
- (0,2) = 'G'
- (0,3) = '.'

- (1,0) = '.'
- (1,1) = 'G'
- (1,2) = '.'
- (1,3) = 'G'

- (2,0) = '.'
- (2,1) = '.'
- (2,2) = 'G'
- (2,3) = '.'

- (3,0) = 'G'
- (3,1) = 'G'
- (3,2) = 'G'
- (3,3) = 'G'

Blue layer rows 4-7:

- (4,0) = 'B'
- (4,1) = 'B'
- (4,2) = 'B'
- (4,3) = 'B'

- (5,0) = 'B'
- (5,1) = 'B'
- (5,2) = '.'
- (5,3) = '.'

- (6,0) = 'B'
- (6,1) = 'B'
- (6,2) = '.'
- (6,3) = '.'

- (7,0) = '.'
- (7,1) = 'B'
- (7,2) = 'B'
- (7,3) = '.'

Now we check each (i,j) for both '.':

- (0,0): green '.'; blue at (4,0) = 'B' -> not both '.' -> output '.'
- (0,1): green 'G'; blue (4,1) = 'B' -> not both '.' -> '.'
- (0,2): green 'G'; blue (4,2) = 'B' -> '.'
- (0,3): green '.'; blue (4,3) = 'B' -> '.'

- (1,0): green '.'; blue (5,0) = 'B' -> '.'
- (1,1): green 'G'; blue (5,1) = 'B' -> '.'
- (1,2): green '.'; blue (5,2) = '.' -> both '.' -> output 'R'
- (1,3): green 'G'; blue (5,3) = '.' -> not both '.' -> '.'

- (2,0): green '.'; blue (6,0) = 'B' -> '.'
- (2,1): green '.'; blue (6,1) = 'B' -> '.'
- (2,2): green 'G'; blue (6,2) = '.' -> not both '.' -> '.'
- (2,3): green '.'; blue (6,3) = '.' -> both '.' -> 'R'

- (3,0): green 'G'; blue (7,0) = '.' -> not both '.' -> '.'
- (3,1): green 'G'; blue (7,1) = 'B' -> '.'
- (3,2): green 'G'; blue (7,2) = 'B' -> '.'
- (3,3): green 'G'; blue (7,3) = '.' -> '.'

Thus output grid:

Row 0: . . . .
Row 1: . . R .
Row 2: . . . R
Row 3: . . . .

Matches the given output. Good.

Now we need to apply the same rule to the test input.

Test Input:

```
. G . G
G G G .
. . . G
G G G .
. . B B
. . B B
. B . .
B B . .
```

Let's parse. 8 rows, 4 columns each.

Rows:

0: ". G . G"
1: "G G G ."
2: ". . . G"
3: "G G G ."
4: ". . B B"
5: ". . B B"
6: ". B . ."
7: "B B . ."

We need to check each cell (i,j) for i=0..3, j=0..3. For each, check if green layer cell (i,j) is '.' and blue layer cell (i+4,j) is '.'.

Let's index.

Green layer rows 0-3:

Row 0: (0,0)='.', (0,1)='G', (0,2)='.', (0,3)='G'
Row 1: (1,0)='G', (1,1)='G', (1,2)='G', (1,3)='.'
Row 2: (2,0)='.', (2,1)='.', (2,2)='.', (2,3)='G'
Row 3: (3,0)='G', (3,1)='G', (3,2)='G', (3,3)='.'

Blue layer rows 4-7:

Row 4: (4,0)='.', (4,1)='.', (4,2)='B', (4,3)='B'
Row 5: (5,0)='.', (5,1)='.', (5,2)='B', (5,3)='B'
Row 6: (6,0)='.', (6,1)='B', (6,2)='.', (6,3)='.'
Row 7: (7,0)='B', (7,1)='B', (7,2)='.', (7,3)='.'

Now we need to check each (i,j):

- (0,0): green '.'; blue (4,0)='.' -> both '.' -> output 'R'
- (0,1): green 'G'; blue (4,1)='.' -> not both '.' -> '.'
- (0,2): green '.'; blue (4,2)='B' -> not both '.' -> '.'
- (0,3): green 'G'; blue (4,3)='B' -> '.'

- (1,0): green 'G'; blue (

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A playing field viewed from above, showing two defensive squads arranged in 4×4 zones—green defenders on one half, blue on the other—with gaps in their coverage. What to do: Overlay both formations. Where neither team has a defender stationed, the striker's shot blazes through, marked red in the goal grid. Grid details: Input is 4 wide by 8 tall, two 4×4 defensive zones stacked. Output is a 4×4 target grid. Background is empty pitch (black)."

We have training examples. Example 1: Input grid 4x8? Let's examine. Example 1 Input:

```
. G G .
. G . G
. . G .
G G G G
B B B B
B B . .
B B . .
. B B .
```

That's 8 rows, each 4 columns. Yes. Output:

```
. . . .
. . R .
. . . R
. . . .
```

So output is 4x4 grid. The rule: overlay both formations (green and blue). Where neither team has a defender stationed, the striker's shot blazes through, marked red in the goal grid. So we need to find cells that are empty (.) in both the green zone and the blue zone? But the input has two 4x4 zones stacked: top 4 rows are green zone? Actually the description: "two defensive squads arranged in 4×4 zones—green defenders on one half, blue on the other—with gaps in their coverage." So maybe the top 4 rows are green defenders, bottom 4 rows are blue defenders. But the input shows green cells in top rows, blue cells in bottom rows. Let's confirm: In input, first 4 rows: row1: . G G . ; row2: . G . G ; row3: . . G . ; row4: G G G G. These are green defenders. Bottom 4 rows: row5: B B B B ; row6: B B . . ; row7: B B . . ; row8: . B B . . Wait row8: . B B . . Actually row8: . B B . . Wait row8 has 4 columns: . B B . . Wait that's 5 columns? Let's check: The input lines: "B B . ." is 4 columns: B, space, B, space, ., space, .? Actually the input lines are separated by spaces? The example shows each row as " . G G . " etc. But the formatting might be ambiguous. Let's parse each row: The input lines are:

1. ". G G ."
2. ". G . G"
3. ". . G ."
4. "G G G G"
5. "B B B B"
6. "B B . ."
7. "B B . ."
8. ". B B ."

Wait row8: ". B B ." is 4 columns: ., B, B, . . Yes. So bottom 4 rows: rows 5-8. They contain B's and .s. So indeed top 4 rows are green zone, bottom 4 rows are blue zone.

Now the output: 4x4 grid. The rule: overlay both formations. Where neither team has a defender stationed, the striker's shot blazes through, marked red in the goal grid. So we need to find cells that are empty in both the green zone and the blue zone. But the output shows some R's. Let's compute.

We need to overlay the two 4x4 zones: For each cell (i,j) in 4x4 grid, we look at the cell in the green zone (top 4 rows) and the cell in the blue zone (bottom 4 rows). If both are empty (.), then we mark R in output. If either has a defender (G or B), then output is .? But the output shows some R's. Let's compute.

Let's index rows 1-4 for green zone, rows 5-8 for blue zone. For each column 1-4.

Green zone:

Row1: . G G .
Row2: . G . G
Row3: . . G .
Row4: G G G G

Blue zone:

Row5: B B B B
Row6: B B . .
Row7: B B . .
Row8: . B B .

Now overlay: For each cell (r,c) where r=1..4, c=1..4:

- (1,1): green ., blue B -> at least one defender -> output .
- (1,2): green G, blue B -> output .
- (1,3): green G, blue B -> output .
- (1,4): green ., blue B -> output .
- (2,1): green ., blue B -> .
- (2,2): green G, blue B -> .
- (2,3): green ., blue . -> both empty -> output R
- (2,4): green G, blue . -> .
- (3,1): green ., blue B -> .
- (3,2): green ., blue B -> .
- (3,3): green G, blue . -> .
- (3,4): green ., blue . -> R
- (4,1): green G, blue . -> .
- (4,2): green G, blue B -> .
- (4,3): green G, blue . -> .
- (4,4): green G, blue . -> .

So we get R at (2,3) and (3,4). That matches output: row1: . . . . ; row2: . . R . ; row3: . . . R ; row4: . . . . . Yes.

So rule: For each cell in 4x4 grid, if both the corresponding cell in the green zone (top 4 rows) and the blue zone (bottom 4 rows) are empty (.), then output R; else output . (black). So basically we overlay the two 4x4 zones and find cells that are empty in both.

Now we need to apply to test input. The test input is:

```
. G . G
G G G .
. . . G
G G G .
. . B B
. . B B
. B . .
B B . .
```

Wait let's parse. The test input lines:

1. ". G . G"
2. "G G G ."
3. ". . . G"
4. "G G G ."
5. ". . B B"
6. ". . B B"
7. ". B . ."
8. "B B . ."

But we need to confirm each row has 4 columns. Let's check each:

Row1: . G . G -> 4 columns: ., G, ., G
Row2: G G G . -> 4 columns: G, G, G, .
Row3: . . . G -> ., ., ., G
Row4: G G G . -> G, G, G, .
Row5: . . B B -> ., ., B, B
Row6: . . B B -> ., ., B, B
Row7: . B . . -> ., B, ., .
Row8: B B . . -> B, B, ., .

Yes.

So top 4 rows are green zone, bottom 4 rows are blue zone.

We need to overlay and find cells that are empty in both zones.

Let's compute.

Green zone (rows 1

We need to parse the problem. It's a grid transformation puzzle. We have a metaphorical description: "What you see: A cathedral window composed of two lattice screens stacked vertically, one of green glass and one of blue, each with certain panes absent. What to do: Align the two screens. Where both have absent panes at the same position, the rosy exterior light floods through, marking those floor tiles red. Grid details: Input is 4 wide by 8 tall, two 4×4 glass screens. Output is a 4×4 floor illumination pattern. Background is dark stone (black)."

We have training examples. Example 1: Input grid is 4 wide by 8 tall? Let's examine. Example 1 Input:

```
. G G .
. G . G
. . G .
G G G G
B B B B
B B . .
B B . .
. B B .
```

That's 8 rows, each 4 columns. So yes 4x8. The first 4 rows are the green screen? The next 4 rows are the blue screen? Let's check: The first 4 rows contain G and .; the next 4 rows contain B and .; yes. So the input is two 4x4 screens stacked vertically: top 4 rows are green screen, bottom 4 rows are blue screen. The output is 4x4 grid. Output:

```
. . . .
. . R .
. . . R
. . . .
```

So output has R at positions where both screens have absent panes (i.e., '.' in both). Let's verify: For each position (row, col) in 4x4, we look at top screen (row 0-3) and bottom screen (row 4-7). If both are '.' then output 'R', else '.'? Let's test with example.

Let's index rows 0-3 for green, 4-7 for blue. Let's create a table:

Row 0: ". G G ."
Row 1: ". G . G"
Row 2: ". . G ."
Row 3: "G G G G"

Row 4: "B B B B"
Row 5: "B B . ."
Row 6: "B B . ."
Row 7: ". B B ."

Now we need to compute output 4x4. Let's compute each cell:

- (0,0): green '.'; blue 'B' (row 4 col 0). Not both '.' => output '.'.
- (0,1): green 'G'; blue 'B' => '.'.
- (0,2): green 'G'; blue 'B' => '.'.
- (0,3): green '.'; blue 'B' => '.'.

Row 0 output: ". . . ."

- (1,0): green '.'; blue 'B' => '.'.
- (1,1): green 'G'; blue 'B' => '.'.
- (1,2): green '.'; blue '.' (row 5 col 2). Both '.' => 'R'.
- (1,3): green 'G'; blue '.' (row 5 col 3). Not both '.' => '.'.

Row 1 output: ". . R ."

- (2,0): green '.'; blue 'B' => '.'.
- (2,1): green '.'; blue 'B' => '.'.
- (2,2): green 'G'; blue '.' (row 6 col 2). Not both '.' => '.'.
- (2,3): green '.'; blue '.' (row 6 col 3). Both '.' => 'R'.

Row 2 output: ". . . R"

- (3,0): green 'G'; blue '.' (row 7 col 0). Not both '.' => '.'.
- (3,1): green 'G'; blue 'B' => '.'.
- (3,2): green 'G'; blue 'B' => '.'.
- (3,3): green 'G'; blue '.' (row 7 col 3). Not both '.' => '.'.

Row 3 output: ". . . ."

Matches output. So rule: For each cell, if both top and bottom screens have '.' (absent pane), output 'R', else '.'.

But we need to confirm that there are no other colors in output. The output only uses '.' and 'R'. So the transformation is: Align the two screens (top and bottom). Where both have absent panes at same position, mark that floor tile red. So yes.

Now we need to apply to test input.

Test Input:

```
. G . G
G G G .
. . . G
G G G .
. . B B
. . B B
. B . .
B B . .
```

Let's parse. 8 rows, 4 columns. Top 4 rows are green screen. Bottom 4 rows are blue screen.

Let's list them:

Row 0: ". G . G"
Row 1: "G G G ."
Row 2: ". . . G"
Row 3: "G G G ."

Row 4: ". . B B"
Row 5: ". . B B"
Row 6: ". B . ."
Row 7: "B B . ."

We need to produce 4x4 output grid. For each cell (r,c) where r=0..3, c=0..3, we check if both top and bottom screens have '.' at that position. If yes, output 'R', else '.'.

Let's compute.

We'll create a table.

Indices: row 0-3 for green, row 4-7 for blue.

Let's write them in a grid:

Green screen (rows 0-3):

Row 0: col0 '.', col1 'G', col2 '.', col3 'G'
Row 1: col0 'G', col1 'G', col2 'G', col3 '.'
Row 2: col0 '.', col1 '.', col2 '.', col3 'G'
Row 3: col0 'G', col1 'G', col2 'G', col3 '.'

Blue screen (rows 4-7):

Row 4: col0 '.', col1 '.', col2 'B', col3 'B'
Row 5: col0 '.', col1 '.', col2 'B', col3 'B'
Row 6: col0 '.', col1 'B', col2 '.', col3 '.'
Row 7: col0 'B', col1 'B', col2 '.', col3 '.'

Now compute output.

We'll produce 4x4 grid.

Let's compute each cell:

- (0,0): green '.'; blue '.' (row 4 col 0). Both '.' => 'R'.
- (0,1): green 'G'; blue '.' (row 4 col 1). Not both '.' => '.'.
- (0,2): green '.'; blue 'B' (row 4 col 2). Not both '.' => '.'.
- (0,3): green 'G'; blue 'B' (row 4 col 3). Not both '.' => '.'.

Row 0 output: "R . . ."

- (1,0): green 'G'; blue '.' (row 5 col 0). Not both '.' => '.'.
- (1,1): green 'G'; blue '.' (row 5 col 1). Not both '.' => '.'.
- (1,2): green 'G'; blue 'B' (row 5 col 2). Not both '.' => '.'.
- (1,3): green '.'; blue 'B' (row 5 col 3). Not both '.' => '.'.

Row 1 output: ". . . ."

- (2,0): green '.'; blue '.' (row 6 col 0). Both '.' => 'R'.
- (2,1): green '.'; blue 'B' (row 6 col 1). Not both '.' => '.'.
- (2,2): green '.'; blue '.' (row 6 col 2). Both '.' => 'R'.
- (2,3): green 'G'; blue '.' (row 6 col 3). Not both '.' => '.'.

We need to solve a grid transformation puzzle. The description: "You are solving a grid transformation puzzle. You are given a metaphorical description of the transformation, training examples, and a test input grid.

Color key: .=black B=blue R=red G=green Y=yellow X=grey M=magenta O=orange A=azure W=maroon

## Metaphorical Description

What you see: A fortification cross-section: two defensive walls, one greenstone and one bluestone, each with narrow openings scattered across their face.
What to do: Find positions where both walls have openings aligned. Fire arrows pass through these double slits and ignite the keep wall behind, marked red.
Grid details: Input is 4 columns by 8 rows, two 4×4 wall faces stacked. Output is a 4×4 keep wall. Background is unburnt stone (black).

Before predicting the output, perform a Conceptual Digestion:
1. Identify the CAST: What roles do different grid elements play?
2. Identify the AFFORDANCES: What can each element do or have done to it?
3. Identify the TRANSFORMATION RULE: What is the precise rule that maps input to output?

Then apply the rule to the test input to predict the output grid.

## Training Examples

Example 1:
Input:
. G G .
. G . G
. . G .
G G G G
B B B B
B B . .
B B . .
. B B .
Output:

.. . R

Test Input:
. G . G
G G G .
. . . G
G G G .
. . B B
. . B B
. B . .
B B . .

Think step by step. After your reasoning, you MUST write out the complete predicted output grid using these single-character color codes:
Color key: .=black B=blue R=red G=green Y=yellow X=grey M=magenta O=orange A=azure W=maroon

At the very end of your response, write the complete output grid inside a clearly labeled block like this:
ANSWER:
.. etc"

We need to produce the output grid for the test input. We have only one training example. We need to deduce the transformation rule.

Let's parse the training example.

Input grid: 4 columns by 8 rows. So 8 rows, each row has 4 characters. The input is:

Row1: . G G .
Row2: . G . G
Row3: . . G .
Row4: G G G G
Row5: B B B B
Row6: B B . .
Row7: B B . .
Row8: . B B .

Wait, the input lines: Let's list them:

1: . G G .
2: . G . G
3: . . G .
4: G G G G
5: B B B B
6: B B . .
7: B B . .
8: . B B .

But the example shows 8 rows? Let's check: The example input lines:

```
. G G .
. G . G
. . G .
G G G G
B B B B
B B . .
B B . .
. B B .
```

Yes, 8 rows. Good.

Output grid: 4 columns by 4 rows. Output lines:

```
. . . .
. . R .
. . . R
. . . .
```

Wait, the output lines: The example output shows:

```
. . . .
. . R .
. . . R
. . . .
```

But the example output in the prompt is:

```
. . . .
. . R .
. . . R
. . . .
```

But the prompt shows:

```
. . . .
. . R .
. . . R
. . . .
```

But the actual example output in the prompt is:

```
. . . .
. . R .
. . . R
. . . .
```

Wait, the prompt shows:

```
. . . .
. . R .
. . . R
. . . .
```

But the prompt shows:

```
. . . .
. . R .
. . . R
. . . .
```

But the prompt shows:

```
. . . .
. . R .
. . . R
. . . .
```

But the prompt shows:

```
. . . .
. . R .
. . . R
. . . .
```

But the prompt shows:

```
. . . .
. . R .
. . . R
. . . .
```

Wait, I'm repeating. Let's just capture the output: 4 rows, each 4 columns. The output grid is:

Row1: . . . .
Row2: . . R .
Row3: . . . R
Row4: . . . .

But the example output in the prompt is:

```
. . . .
. . R .
. . . R
. . . .
```

But the prompt shows:

```
. . . .
. . R .
. . . R
. . . .
```

But the prompt shows:

```
. . . .
. . R .
. . . R
. . . .
```

Ok.

Now we need to deduce the transformation rule.

The metaphor: "What you see: A fortification cross-section: two defensive walls, one greenstone and one bluestone, each with narrow openings scattered across their face. What to do: Find positions where both walls have openings aligned. Fire arrows pass through these double slits and ignite the keep wall behind, marked red. Grid details: Input is 4 columns by 8 rows, two 4×4 wall faces stacked. Output is a 4×4 keep wall. Background is unburnt stone (black)."

So the input grid has two 4x4 wall faces stacked: top 4 rows are green wall, bottom 4 rows are blue wall. Each wall has openings (represented by '.' maybe?). The output is a 4x4 keep wall: positions where both walls have openings aligned produce red cells. The rest are black ('.').

Thus the rule: For each column and row index (0-3), if the cell in the top 4 rows (green wall) at that position is '.' (open) AND the cell in the bottom 4 rows (blue wall) at that position is '.' (open), then the output cell at that position is 'R' (red). Otherwise, output '.' (black). That seems plausible.

Let's test with the example.

Input top 4 rows (green wall):

Row1: . G G .
Row2: . G . G
Row3: . . G .
Row4: G G G G

Input bottom 4 rows (blue wall):

Row5: B B B B
Row6: B B . .
Row7: B B . .
Row8: . B B .

We need to align them: The top 4 rows correspond to rows 0-3, bottom 4 rows correspond to rows 4-7. For each column 0-3, we check if top cell is '.' and bottom cell is '.

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: An orange sky stretches above an azure launchpad. Clustered on or near the pad, colorful balloons of various shapes wait, freshly inflated and straining against the ground. Each balloon is a tight knot of same-colored or distinctly colored cells, full of lift. What to do: Release the balloons. Each one rises into the orange sky — the more air inside it, the higher it floats. A balloon's buoyancy is measured by its fullness: every breath of color it holds carries it one story higher. The launchpad stays bolted to the earth, and the sky fills in behind each balloon as it ascends. Grid details: The sky is 8 columns wide and 8 stories tall. The azure launchpad is the ground floor, permanent and immovable. The orange atmosphere fills every space not claimed by a balloon. Each balloon keeps its shape perfectly as it drifts upward — no stretching, no tumbling, just a clean vertical ascent."

We have training examples. Example 1: Input grid 8x8. Output grid 8x8. We need to deduce transformation rule.

Let's analyze Example 1.

Input grid:

Row1: O O O O O O O O

We need to interpret. The input has some colored cells: W (maroon) at row6 col2, row7 col1-3, R (red) at row7 col6-8. The rest are O (orange). The bottom row (row8) is A (azure). The top rows are all O.

The output shows that the W cluster moved upward: originally at row6 col2, row7 col1-3. In output, W cluster is at row2 col2, row3 col1-3. So it moved up 4 rows? Let's check: The W cluster originally had shape: a 3x2 shape? Actually coordinates: (row6, col2), (row7, col1), (row7, col2), (row7, col3). That's a shape like a small cluster. In output, W cluster at (row2, col2), (row3, col1), (row3, col2), (row3, col3). So moved up 4 rows (row6->row2, row7->row3). Similarly, the R cluster originally at row7 col6-8. In output, R cluster at row4 col6-8. So moved up 3 rows? Wait row7->row4 is 3 rows up. But maybe the rule is that each balloon rises until it hits the top or until it would collide with other balloons? Let's analyze.

The input has a ground floor row8 of A. The sky is O. The balloons are W and R. The rule: release balloons, they rise until they hit the top? But the output shows W cluster moved up 4 rows, R cluster moved up 3 rows. Why different? Maybe because the W cluster had more cells (4 cells) so it rises higher? The metaphor says: "The more air inside it, the higher it floats. A balloon's buoyancy is measured by its fullness: every breath of color it holds carries it one story higher." So each cell of a balloon gives it one story of lift? So the number of cells in a balloon determines how many rows it moves up. That seems plausible: W cluster has 4 cells, so it moves up 4 rows. R cluster has 3 cells, so it moves up 3 rows. That matches: W cluster moved from rows 6-7 to rows 2-3 (4 rows up). R cluster moved from row7 to row4 (3 rows up). But we need to check if there is any obstacle: The sky is O, but the balloons cannot pass through each other or the ground. They also cannot go above the top row? The top row is row1. The W cluster moved to row2-3, not row1. But why not row1? Because maybe the shape cannot go above row1 due to shape constraints? Let's examine shape: W cluster shape: a 3x2 shape? Actually shape: coordinates relative: (0,0) at row6 col2? Let's map shape: row6 col2, row7 col1, row7 col2, row7 col3. So shape is like a "T" shape? Actually it's like a 3-block horizontal line at row7 col1-3, plus one block above at row6 col2. So shape is like a T shape oriented with the stem downwards. When moving up, the shape must maintain its shape. So moving up 4 rows: new positions: row2 col2, row3 col1-3. That shape is same orientation. So it moved up 4 rows. But could it move up 5 rows? That would put it at row1 col2, row2 col1-3. That would still be within grid. But maybe it cannot because the shape would overlap with something? Let's check: At row1 col2, row2 col1-3. Are there any obstacles? The top row originally had O cells. But after moving, the shape would occupy row1 col2, row2 col1-3. That would be fine. But maybe the rule is that the balloon stops when it would collide with another balloon or the top? But there is no other balloon above. So why didn't it go to row1? Let's examine the R cluster: shape: row7 col6-8 (3 horizontal cells). It moved up 3 rows to row4 col6-8. Could it move up 4 rows to row3 col6-8? That would be row3 col6-8. That would be within grid. But maybe it would collide with the W cluster? Let's check: W cluster after moving up 4 rows is at row2 col2, row3 col1-3. T

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: An azure dock line runs along the bottom of the harbor cross-section. Colored cargo bundles rest near the dock, submerged in the murky orange water of the harbor. What to do: Each cargo bundle floats upward — the more crates lashed together, the more trapped air buoys them higher. The dock stays anchored at the bottom. Each bundle rises intact through the orange water, preserving its packing arrangement. Grid details: 8-berth harbor, 8 fathoms deep. Azure bottom is the dock. Orange is harbor water. Colored clusters are cargo bundles."

We have training example 1. Input grid 8x8. Output grid 8x8. We need to deduce transformation rule.

Let's analyze training example 1.

Input grid:

Row1: O O O O O O O O
Row2: O O O O O O O O
Row3: O O O O O O O O
Row4: O O O O O O O O
Row5: O O O O O O O O
Row6: O W O O O O O O
Row7: W W W O O R R R
Row8: A A A A A A A A

Output grid:

Row1: O O O O O O O O
Row2: O W O O O O O O
Row3: W W W O O O O O
Row4: O O O O O R R R
Row5: O O O O O O O O
Row6: O O O O O O O O
Row7: O O O O O O O O
Row8: A A A A A A A A

We need to interpret. Input: bottom row (row8) is A A A A A A A A (azure). Row7: W W W O O R R R. Row6: O W O O O O O O. Others all O.

Output: bottom row remains A's. Row7 all O. Row6 all O. Row5 all O. Row4: O O O O O R R R. Row3: W W W O O O O O. Row2: O W O O O O O O. Row1 all O.

So basically the colored clusters (W and R) moved upward. The W cluster originally at row6 col2 and row7 col1-3. In output, W cluster moved to row3 col1-3 and row2 col2? Wait let's map coordinates.

Let's index rows 1-8 top to bottom, columns 1-8 left to right.

Input:

Row6: col1 O, col2 W, col3 O, col4 O, col5 O, col6 O, col7 O, col8 O.
Row7: col1 W, col2 W, col3 W, col4 O, col5 O, col6 R, col7 R, col8 R.

So W cluster: cells (6,2), (7,1),(7,2),(7,3). R cluster: cells (7,6),(7,7),(7,8).

Output:

Row2: col1 O, col2 W, col3 O, col4 O, col5 O, col6 O, col7 O, col8 O.
Row3: col1 W, col2 W, col3 W, col4 O, col5 O, col6 O, col7 O, col8 O.
Row4: col1 O, col2 O, col3 O, col4 O, col5 O, col6 R, col7 R, col8 R.

So W cluster moved up 4 rows: from row6 to row2? Actually (6,2) moved to (2,2). (7,1) moved to (3,1). (7,2) moved to (3,2). (7,3) moved to (3,3). So cluster shape preserved but moved upward by 4 rows. R cluster moved up 3 rows: from row7 to row4. (7,6) -> (4,6). (7,7) -> (4,7). (7,8) -> (4,8). So R cluster moved up 3 rows.

But why different distances? The rule might be: each cluster floats upward until it hits the top or another cluster? But the clusters are moving upward until they reach the top? Let's examine.

In input, W cluster is at rows 6-7. In output, W cluster is at rows 2-3. So it moved up until it reached row2? Actually row2 is second row from top. So W cluster moved up until it reached row2? But why not row1? Because maybe it stops when it would collide with another cluster? But there is no other cluster above. But maybe the rule is that each cluster moves upward until it reaches the topmost row that is not occupied by any other cluster? But there is no other cluster above. So why not row1? Let's check R cluster: moved up to row4. That is 3 rows up. But why not row1? Because maybe R cluster is blocked by W cluster? But W cluster is to the left, not overlapping. So maybe the rule is that each cluster moves upward until it reaches the topmost row that is not occupied by any other cluster of the same color? That doesn't make sense.

Let's analyze the metaphor: "Each cargo bundle floats upward — the more crates lashed together, the more trapped air buoys them higher. The dock stays anchored at the bottom. Each bundle rises intact through the orange water, preserving its packing arrangement." So each cluster (bundle) floats upward. The more crates lashed together, the more trapped air buoys them higher. So bigger clusters float higher. So maybe the rule: clusters move upward by a number of rows equal to their size? Let's test: W cluster size 4 cells. It moved up 4 rows? Yes, from row6 to row2 (difference 4). R cluster size 3 cells. It moved up 3 rows? Yes, from row7 to row4 (difference 3). That matches! So rule: each cluster moves upward by a number of rows equal to its size (number of cells). The clusters preserve shape and relative positions. They cannot pass through other clusters or the top? But they can float until they hit the top? But if cluster size is large, it might go above top? But maybe the grid is large enough. But we need to consider collisions: if two clusters would overlap after moving, maybe they stop earlier? But in this example, they didn't overlap.

Also, the bottom row (dock) remains anchored at bottom. The water is orange. So the clusters float upward through orange water. So the rule: each cluster moves upward by a number of rows equal to its size. The bottom row remains unchanged. The water remains orange. The clusters preserve shape.

We need to solve a grid transformation puzzle. We have a metaphorical description, training examples, and test input. We need to deduce the transformation rule. Let's analyze the training example.

We have an 8x8 grid. Input and output grids are given. Let's rewrite them with coordinates. We'll use row 0 at top, row 7 at bottom. Columns 0-7 left to right.

Input Example 1:

Row0: O O O O O O O O
Row1: O O O O O O O O
Row2: O O O O O O O O
Row3: O O O O O O O O
Row4: O O O O O O O O
Row5: O W O O O O O O
Row6: W W W O O R R R
Row7: A A A A A A A A

Output Example 1:

Row0: O O O O O O O O
Row1: O W O O O O O O
Row2: W W W O O O O O
Row3: O O O O O R R R
Row4: O O O O O O O O
Row5: O O O O O O O O
Row6: O O O O O O O O
Row7: A A A A A A A A

We need to find transformation rule mapping input to output.

Observations: The bottom row (row7) remains unchanged: all A's. The top rows (rows0-4) remain unchanged except for some changes? Let's compare row by row.

Input row0: all O. Output row0: all O. unchanged.

Row1: all O. Output row1: O W O O O O O O. So at column1 (index1) changed from O to W. Input row1 had all O. So a W appears at (row1, col1). Where did that W come from? In input, there were W's at row5 col1, row6 col0-2. So maybe W's moved upward? Let's see.

Input row5: O W O O O O O O. Output row5: all O. So the W at (5,1) moved up to (1,1). Input row6: W W W O O R R R. Output row6: all O. So the W's at (6,0),(6,1),(6,2) moved up to (2,0),(2,1),(2,2)? Let's check output row2: W W W O O O O O. Yes, output row2 has W at columns 0,1,2. So W's moved upward by 4 rows? Wait: (6,0) -> (2,0) is up 4 rows. (6,1) -> (2,1) up 4 rows. (6,2) -> (2,2) up 4 rows. (5,1) -> (1,1) up 4 rows. So all W's moved up 4 rows. But also the R's at (6,5),(6,6),(6,7) moved up? Let's check output row3: O O O O O R R R. Yes, R's moved up 3 rows? Wait: (6,5) -> (3,5) is up 3 rows. (6,6) -> (3,6) up 3 rows. (6,7) -> (3,7) up 3 rows. So R's moved up 3 rows. But maybe they moved up until they hit something? Let's examine.

Input row6: W W W O O R R R. Output row3: O O O O O R R R. So R's moved up 3 rows. But why 3? Maybe they moved up until they hit the topmost row that is not O? But there is no other color above them. Let's check the top rows: row0-4 all O. So R's could have moved up 6 rows to row0? But they didn't. So maybe they moved up until they hit a row that contains a different color? But there is no other color. So maybe they moved up until they hit the first row that contains a non-O? But there is none. So maybe they moved up until they hit the first row that contains a W? But there is no W above them. So maybe they moved up until they hit the first row that contains a different color than themselves? But there is no other color. So maybe they moved up until they hit the first row that contains a color that is not O and not the same as them? But there is none. So maybe they moved up until they hit the first row that contains a color that is not O and not the same as them? But again none.

Alternatively, maybe the rule is that each colored group (W, R, etc.) moves upward until it reaches the topmost row that is not the same color as the group? But again none.

Let's examine the transformation of W's: They moved up 4 rows. R's moved up 3 rows. So maybe the number of rows moved depends on the color? Or maybe the number of rows moved depends on the distance to the nearest non-O cell? But there is none.

Wait, maybe the rule is that each colored group moves upward until it reaches the first row that contains a different color group? But there is no other color group above them. So maybe they move upward until they reach the first row that contains a color that is not O and not the same as them? But again none.

Let's examine the positions of the groups in input: W group at row5 col1 and row6 col0-2. R group at row6 col5-7. In output: W group at row1 col1 and row2 col0-2. R group at row3 col5-7. So W group moved up 4 rows, R group moved up 3 rows. So maybe the rule is that each group moves upward until it reaches the first row that contains a different color group? But there is no other group above them. So maybe they move upward until they reach the first row that contains a color that is not O and not the same as them? But again none.

Alternatively, maybe the rule is that each group moves upward until it reaches the first row that contains a color that is not O and not the same as them, but if there is none, they move up until they reach the topmost row? But they didn't reach topmost row. So maybe they stop at the first row that contains a color that is not O and not the same as them, but if there is none, they stop at the row just above the topmost row? But that would be row0? But they didn't.

Let's examine the difference: W group moved up 4 rows, R group moved up 3 rows. The difference is 1 row. Maybe the rule is that each group moves upward until it reaches the first row that contains a color that is not O an

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: An azure bedrock layer lies at the base of the geological cross-section. Colored mineral deposits sit near the bedrock, each a different ore cluster, embedded in orange sedimentary matrix. What to do: Each mineral vein is thrust upward by tectonic forces — the more crystalline mass in the deposit, the greater the uplift. The bedrock stays immovable. Each deposit preserves its crystal structure as it's pushed through the sediment, orange matrix backfilling the void. Grid details: 8-column cross-section, 8 strata deep. Azure bottom is bedrock. Orange is sedimentary matrix. Colored clusters are mineral deposits."

We have training example 1. Input grid 8x8. Output grid 8x8. We need to deduce transformation rule.

Let's analyze training example 1.

Input grid:

Row1: O O O O O O O O
Row2: O O O O O O O O
Row3: O O O O O O O O
Row4: O O O O O O O O
Row5: O O O O O O O O
Row6: O W O O O O O O
Row7: W W W O O R R R
Row8: A A A A A A A A

So bottom row (row8) is all A (azure). Row7 has W W W O O R R R. Row6 has O W O O O O O O. Row1-5 all O.

Output grid:

Row1: O O O O O O O O
Row2: O W O O O O O O
Row3: W W W O O O O O
Row4: O O O O O R R R
Row5: O O O O O O O O
Row6: O O O O O O O O
Row7: O O O O O O O O
Row8: A A A A A A A A

So transformation: The colored clusters (W and R) moved upward? Let's examine.

Input: W cluster: at row6 col2 (W). Row7 col1-3 are W. So W cluster shape: a 3x2 block? Actually row6 col2 is W, row7 col1-3 are W. So shape: a 3x2 cluster with a missing at row6 col1? Wait row6 col1 is O. So shape: row6 col2 W; row7 col1-3 W. So shape like a "L" shape? Let's map coordinates: using 1-indexed rows from top.

Input coordinates:

Row6 col2: W
Row7 col1: W
Row7 col2: W
Row7 col3: W

So shape: a 3x2 cluster with missing at row6 col1 and row6 col3? Actually row6 col3 is O. So shape is like a "T" shape? Let's draw:

Row6: . W . . . . . .
Row7: W W W . . R R R

So W cluster is 4 cells: (6,2), (7,1),(7,2),(7,3). R cluster: row7 col5-7: R R R. So R cluster is 3 cells contiguous horizontally.

Now output: W cluster moved upward: row2 col2? Wait output row2 col2 is W. Row3 col1-3 are W. So W cluster moved up by 4 rows? Let's check: Input W cluster at rows 6-7. Output W cluster at rows 2-3. So moved up 4 rows. R cluster moved up: Input R cluster at row7 col5-7. Output R cluster at row4 col5-7. So moved up 3 rows. So each cluster moved upward by some amount. The bedrock (A) stays at bottom row 8. The orange matrix (O) remains at other cells? But in output, many O cells changed to O? Actually output row1-5 all O except where clusters moved. But input had O in all cells except clusters. So O remains O except where clusters moved. But also the clusters moved upward, leaving behind O. So the transformation is: each colored cluster moves upward until it hits bedrock? But bedrock is at bottom row 8. But clusters moved upward, not downward. Wait the metaphor says: "Each mineral vein is thrust upward by tectonic forces — the more crystalline mass in the deposit, the greater the uplift. The bedrock stays immovable. Each deposit preserves its crystal structure as it's pushed through the sediment, orange matrix backfilling the void." So the clusters are pushed upward, not downward. So they move upward until they hit the top? But bedrock is at bottom, so upward movement is away from bedrock. So they move upward until they reach the top? But in output, clusters ended up near top: W cluster at rows 2-3, R cluster at row4. So they moved upward until they hit the top? But there is no obstacle above them except the top boundary. So they moved up until they hit the top boundary? But why did W cluster move 4 rows, R cluster 3 rows? Let's examine distances: Input W cluster at rows 6-7. The top boundary is row1. So maximum upward movement would be 5 rows for row7 cluster? Actually the cluster's topmost cell is at row6 col2. The topmost row is row1. So distance to top is 5 rows. But W cluster moved 4 rows, not 5. So maybe they moved until they hit the topmost row that is not occupied by other clusters? But there were no other clusters above. So why not 5? Let's examine the shape: W cluster has a cell at row6 col2. If it moved up 5 rows, it would be at row1 col2. But output row1 col2 is O. So W cluster didn't move that far. So maybe the rule is: each cluster moves upward until it reaches the first row that is not occupied by any other cluster? But there is no other cluster. So maybe the rule is: each cluster moves upward until it reaches the topmost row that is not occupied by any other cluster? But that would be row1. So still not.

Maybe the rule is: each cluster moves upward until it reaches the topmost row that is not occupied by any other cluster, but also until it reaches the topmost row that is not occupied by any other cluster of the same color? That doesn't make sense.

Let's analyze the R cluster: Input R cluster

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: An azure baking sheet sits at the bottom of the oven. Lumps of differently colored dough rest on or near the sheet, surrounded by the warm orange glow of the oven cavity. What to do: Each lump of dough rises — the more flour kneaded into it, the higher it climbs. Bigger lumps contain more yeast and lift proportionally higher. The baking sheet stays put, and the dough holds its shape as it ascends through the heat. Grid details: 8-wide, 8-tall oven interior. Azure bottom is the baking sheet. Orange is ambient heat. Colored lumps are the dough pieces."

We have training examples. Example 1: Input grid 8x8. Output grid 8x8. We need to deduce transformation rule.

Let's parse Example 1.

Input grid:

Row1: O O O O O O O O
Row2: O O O O O O O O
Row3: O O O O O O O O
Row4: O O O O O O O O
Row5: O O O O O O O O
Row6: O W O O O O O O
Row7: W W W O O R R R
Row8: A A A A A A A A

Output grid:

Row1: O O O O O O O O
Row2: O W O O O O O O
Row3: W W W O O O O O
Row4: O O O O O R R R
Row5: O O O O O O O O
Row6: O O O O O O O O
Row7: O O O O O O O O
Row8: A A A A A A A A

We need to see transformation: The input had W at (row6, col2) and W at (row7, col1-3). R at (row7, col6-8). Output moved W's upward? Let's index coordinates: 1-indexed rows from top. Input: row6 col2 has W. row7 col1-3 W. row7 col6-8 R. Output: row2 col2 has W. row3 col1-3 W. row4 col6-8 R. So W moved up 4 rows? Actually from row6 to row2: moved up 4 rows. W at row7 col1-3 moved to row3 col1-3: moved up 4 rows. R at row7 col6-8 moved to row4 col6-8: moved up 3 rows? Wait row7 to row4 is 3 rows up. But maybe R moved up 3? Let's check: Input row7 col6-8 R. Output row4 col6-8 R. That's 3 rows up. So W moved 4 rows up, R moved 3 rows up. But maybe the rule is that each colored lump rises until it hits something? The bottom row is azure (A). The top rows are orange (O). The lumps are W and R. They rise until they hit the top? But they don't go to top; they stop at some height. Maybe they rise until they hit the topmost row that is not orange? But top row is O. They might rise until they hit the first non-O cell above them? But above them there is only O. So they'd go to top row? But they didn't. So maybe they rise until they hit the first non-O cell above them, but there is none. So maybe they rise until they hit the first non-O cell below them? Wait they are moving upward, so they'd hit something above them. But there is nothing above them except O. So maybe they rise until they hit the first non-O cell below them? That would be downward movement. But they moved upward. So maybe they rise until they hit the first non-O cell below them? That would be downward movement. But they moved upward. So maybe they rise until they hit the first non-O cell above them? But there is none. So maybe they rise until they hit the first non-O cell below them? That would be downward. So not that.

Let's analyze the metaphor: "Each lump of dough rises — the more flour kneaded into it, the higher it climbs. Bigger lumps contain more yeast and lift proportionally higher. The baking sheet stays put, and the dough holds its shape as it ascends through the heat." So lumps of dough (colored lumps) rise. The more flour kneaded into it, the higher it climbs. Bigger lumps contain more yeast and lift proportionally higher. The baking sheet stays put, and the dough holds its shape as it ascends through the heat.

So we have lumps of dough of different sizes. They rise proportionally to their size. The baking sheet stays put at bottom. The dough holds its shape as it ascends. So maybe the transformation is: each colored lump moves upward by a number of rows equal to its size (maybe number of cells in the lump). The lumps maintain shape (so they don't change shape). They don't overlap? They might move until they hit the top or another lump? But they might also stop when they reach the top row? But in example, W lumps moved up 4 rows, R lumps moved up 3 rows. Let's check sizes: W lumps: there are 4 W cells in input: at (6,2) and (7,1-3). That's 4 cells. R lumps: 3 cells at (7,6-8). So W lumps moved up 4 rows, R lumps moved up 3 rows. That matches: each lump moves up by number of cells in the lump. That seems plausible. Let's test: W lumps moved up 4 rows: from row6 to row2 (4 rows up). R lumps moved up 3 rows: from row7 to row4 (3 rows up). So rule: each contiguous group of same color (lump) moves upward by a number of rows equal to the size of the lump. They maintain shape. They don't interact with other lumps? They might pass through each other? But in example, W lumps moved up 4 rows, R lumps moved up 3 rows. They didn't collide because they moved to different columns. But what if lumps overlapped? We need to consider test input.

Also, the bottom row is azure (A). The top rows are orange (O). The lumps are W and R. The lumps are above the baking sheet? Actually the bottom row is

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: An azure springboard stretches across the bottom of the arena. Teams of differently colored athletes stand huddled on or near the board, surrounded by the orange mat of the competition floor. What to do: Each team launches off the springboard in formation — the larger the squad, the higher their vault carries them. They hold their huddle shape mid-air. The springboard stays bolted to the floor, and the mat fills where they stood. Grid details: 8-lane arena, 8 rows high. Azure bottom is the springboard. Orange is the mat. Colored groups are athlete teams."

We have training examples. Example 1: Input grid 8x8. Output grid 8x8. We need to deduce transformation rule.

Let's parse Example 1.

Input grid:

Row1: O O O O O O O O

Row5: O O O O O O O O
Row6: O O O O O O O O
Row7: O O O O O O O O
Row8: A A A A A A A A

We need to interpret transformation. Let's label coordinates: row 1 top, row 8 bottom. Column 1 left, column 8 right.

Input: There is a group of W (maroon) at row6 col2? Wait row6: "O W O O O O O O" so W at (row6, col2). Row7: "W W W O O R R R" so W at (row7, col1-3). R at (row7, col6-8). A at row8 all columns.

Output: Row2: "O W O O O O O O" so W at (row2, col2). Row3: "W W W O O O O O" so W at (row3, col1-3). Row4: "O O O O O R R R" so R at (row4, col6-8). Row5-7 all O. Row8 same A.

So transformation: The W group moved upward from rows 6-7 to rows 2-3. The R group moved upward from row7 col6-8 to row4 col6-8. The A group stayed at bottom row8. The O background remains O except where moved groups replaced O. The O at row5-7 become O again after groups moved.

Essentially, the groups (W and R) moved upward until they hit the top of the arena? But they didn't go all the way to top; they moved to row2-3 and row4. Let's analyze distances: W group originally at rows 6-7. After transformation, at rows 2-3. So moved up 4 rows. R group originally at row7 col6-8. After transformation, at row4 col6-8. Moved up 3 rows. So maybe they moved up until they hit the topmost non-O cell? But there is no other non-O cells above them except O. So maybe they moved up until they hit the top row? But they didn't go to row1. They ended at row2-3 for W, row4 for R. So maybe they moved up until they hit the next non-O cell (like the A row at bottom? No, that's below). Wait maybe they moved up until they hit the next non-O cell in the same column? But there is no other non-O cell above them. So maybe they moved up until they hit the topmost row that is not the bottom row? But that seems arbitrary.

Let's examine the metaphor: "An azure springboard stretches across the bottom of the arena. Teams of differently colored athletes stand huddled on or near the board, surrounded by the orange mat of the competition floor. What to do: Each team launches off the springboard in formation — the larger the squad, the higher their vault carries them. They hold their huddle shape mid-air. The springboard stays bolted to the floor, and the mat fills where they stood."

Interpretation: The bottom row is azure (A). The springboard is at bottom row. The teams (colored groups) stand on or near the board. They launch off the springboard in formation. The larger the squad, the higher their vault carries them. They hold their huddle shape mid-air. The springboard stays bolted to the floor, and the mat fills where they stood.

So transformation: The colored groups (teams) are moved upward (vault) from their original positions to new positions above the springboard. The height of the vault depends on the size of the squad: larger squads go higher. They maintain their shape (huddle shape). The springboard stays at bottom row (unchanged). The mat (orange) fills where they stood (i.e., the original positions become orange). So the transformation is: For each colored group, we compute the size of the group (number of cells). The group is moved upward by a number of rows equal to something like group size? But in example, W group size: 4 cells (row6 col2, row7 col1-3). R group size: 3 cells (row7 col6-8). They moved up 4 rows for W, 3 rows for R. That matches group size! Indeed, W group size 4 moved up 4 rows. R group size 3 moved up 3 rows. So rule: Each group moves upward by a number of rows equal to its size. They maintain shape. The original cells become O (orange). The bottom row remains A. The springboard stays bolted to the floor (so bottom row remains unchanged). The mat fills where they stood (original positions become O). That matches.

Let's test: W group originally at rows 6-7. Move up 4 rows: row6 -> row2, row7 -> row3. That matches output. R group originally at row7 col6-8.

We need to solve a grid transformation puzzle. We have a metaphorical description, training examples, and a test input grid. We need to produce the output grid.

We have to analyze the training example to deduce the transformation rule. Let's parse the training example.

We have an 8x8 grid. Input grid:

Row1: O O O O O O O O
Row2: O O O O O O O O
Row3: O O O O O O O O
Row4: O O O O O O O O
Row5: O O O O O O O O
Row6: O W O O O O O O
Row7: W W W O O R R R
Row8: A A A A A A A A

Output grid:

Row1: O O O O O O O O
Row2: O W O O O O O O
Row3: W W W O O O O O
Row4: O O O O O R R R
Row5: O O O O O O O O
Row6: O O O O O O O O
Row7: O O O O O O O O
Row8: A A A A A A A A

So the transformation moved some colored cells upward? Let's examine.

Input: Row6 has O W O O O O O O. So at row6, column2 is W. Row7 has W W W O O R R R. So row7 columns1-3 are W, columns6-8 are R. Row8 is all A.

Output: Row2 has O W O O O O O O. So the W from row6 moved up to row2. Row3 has W W W O O O O O. So the W's from row7 moved up to row3. Row4 has O O O O O R R R. So the R's from row7 moved up to row4. The rest of the grid is all O except bottom row A.

So the transformation seems to "lift" the colored shapes upward, maybe by a number of rows equal to something like the number of W's? Let's analyze.

Input: The W's are at row6 col2, row7 col1-3. The R's at row7 col6-8. The A's at row8 all columns. The O's fill the rest.

Output: The W's moved up to row2 and row3. The R's moved up to row4. The A's stayed at row8. The O's fill the rest.

So the transformation seems to "lift" each colored shape upward until it hits the top or until it collides with something? But the shapes moved upward by different amounts: W at row6 moved up 4 rows to row2. W at row7 moved up 4 rows to row3. R at row7 moved up 3 rows to row4. So maybe the rule is: For each colored shape (non-O), move it upward until it reaches the first row that is not occupied by the same color? But the shapes moved to different rows.

Let's examine the relative positions: In input, the W shape is a cluster of 4 cells: at (row6,col2), (row7,col1),(row7,col2),(row7,col3). The R shape is a cluster of 3 cells: at (row7,col6),(row7,col7),(row7,col8). The A shape is a cluster of 8 cells: at row8 all columns. The O shape is everything else.

In output, the W shape moved up to rows 2-3: at (row2,col2),(row3,col1),(row3,col2),(row3,col3). The R shape moved up to row4: at (row4,col6),(row4,col7),(row4,col8). The A shape stayed at row8.

So the W shape moved up 4 rows (from row6 to row2, and row7 to row3). The R shape moved up 3 rows (from row7 to row4). The A shape moved up 0 rows (stayed at row8). So maybe the rule is: Each shape moves upward by a number of rows equal to the number of rows it is above the bottom? But that doesn't match: W shape is at rows 6-7, so above bottom by 1-2 rows? Actually bottom row is row8. So W shape is 1-2 rows above bottom. But moved up 4 rows. R shape is also at row7, 1 row above bottom, moved up 3 rows. A shape is at row8, 0 rows above bottom, moved up 0 rows. So maybe the rule is: Each shape moves upward by a number of rows equal to the number of rows between its topmost cell and the bottom row? Let's compute: For W shape, topmost cell is at row6. Bottom row is row8. So distance = 8-6 = 2. But moved up 4 rows. Not match.

Maybe the rule is: Each shape moves upward until it reaches the topmost row that is not occupied by any other shape? But the shapes moved to rows 2-4, leaving rows 1,5-7 empty. So maybe the shapes are moved upward until they reach the first row that is not occupied by any shape of the same color? But there is no other shape of same color. So maybe they move upward until they hit the top row or until they collide with the bottom row? But they didn't hit top row; they ended at row2-4. So maybe they moved upward until they hit the first row that is not occupied by any shape of any color? But row1 is all O, so they could have moved to row1. But they didn't. So maybe they moved upward until they hit the first row that is not occupied by any shape of the same color? But again row1 is all O, so they could have moved to row1. So not that.

Maybe the rule is: Each shape moves upward by a number of rows equal to the number of cells in the shape? Let's test: W shape has 4 cells, moved up 4 rows. R shape has 3 cells, moved up 3 rows. A shape has 8 cells, moved up 0 rows? But 8 cells would move up 8 rows, but bottom row is row8, so moving up 8 rows would go to row0 (outside). So maybe shapes cannot move beyond the top row, so they stop at row1? But A shape didn't move at all. So maybe shapes that are at the bottom row cannot move upward because they are at the bottom? But W shape is not at bottom row; it moved up. So maybe shapes that are at the bottom row cannot move upward because they are anchored? But A shape is at bottom row, so anchored. That matches: A shape anchored at bottom row, cannot move. W shape is not anchored, so moves upward by number of c

We need to solve a grid transformation puzzle. We have a metaphorical description, training examples, and a test input grid. We need to produce the output grid.

We have to analyze the transformation rule from the training example. Let's parse the training example.

We have an 8x8 grid. Input grid:

Row1: O O O O O O O O
Row2: O O O O O O O O
Row3: O O O O O O O O
Row4: O O O O O O O O
Row5: O O O O O O O O
Row6: O W O O O O O O
Row7: W W W O O R R R
Row8: A A A A A A A A

Output grid:

Row1: O O O O O O O O
Row2: O W O O O O O O
Row3: W W W O O O O O
Row4: O O O O O R R R
Row5: O O O O O O O O
Row6: O O O O O O O O
Row7: O O O O O O O O
Row8: A A A A A A A A

We need to understand the transformation. Let's label coordinates: rows 1-8 from top to bottom, columns 1-8 left to right.

Input: The bottom row (row8) is all A (azure). Row7 has W W W O O R R R. Row6 has O W O O O O O O. The rest rows 1-5 are all O.

Output: Row8 remains all A. Row7 becomes all O. Row6 becomes all O. Row5 becomes all O. Row4 has O O O O O R R R. Row3 has W W W O O O O O. Row2 has O W O O O O O O. Row1 remains all O.

So basically the pattern of W and R moved upward? Let's examine.

Input: Row6: O W O O O O O O. Row7: W W W O O R R R. Row8: A A A A A A A A.

Output: Row2: O W O O O O O O. Row3: W W W O O O O O. Row4: O O O O O R R R. Row5: O O O O O O O O. Row6: O O O O O O O O. Row7: O O O O O O O O. Row8: A A A A A A A A.

So the W cluster moved up from row6 to row2? Actually the W cluster originally at row6 col2 (W) moved to row2 col2. The W cluster originally at row7 col1-3 moved to row3 col1-3. The R cluster originally at row7 col6-8 moved to row4 col6-8. So the clusters moved upward by some amount. The bottom row remains unchanged. The top rows become O except where clusters moved.

It seems like the transformation is: For each colored cluster (non-O, non-A?), we "shoot upward" until we hit the top or until we hit something? The description: "Each seedling cluster shoots upward — the more roots in its mass, the taller it grows. The soil bed stays at the base. Each cluster maintains its leaf arrangement as it stretches skyward, orange mulch filling where stems once pressed." The metaphor: azure bottom is soil. Orange is mulch. Colored groups are seedling clusters. The transformation: each cluster shoots upward, the more roots in its mass, the taller it grows. The soil bed stays at the base. Each cluster maintains its leaf arrangement as it stretches skyward, orange mulch filling where stems once pressed.

So we have a bottom row of azure (soil). The clusters are colored groups. They shoot upward, meaning they move upward. The more roots in its mass, the taller it grows. That might mean that the cluster's vertical extent increases? Or the cluster's height increases? The cluster maintains its leaf arrangement as it stretches skyward, orange mulch filling where stems once pressed. So the cluster's shape remains the same relative arrangement, but it moves upward, and the cells that were previously occupied by the cluster become orange (mulch). The bottom row remains azure. The top row might become O if cluster moved above? But the top row remains O in the example.

Let's analyze the cluster shapes.

Input cluster 1: W cluster. In input, W cells: row6 col2, row7 col1-3. So shape: a 2x3 cluster? Actually it's like a shape: row6 col2, row7 col1, col2, col3. So shape like a T? Let's map coordinates:

- (6,2)
- (7,1)
- (7,2)
- (7,3)

So shape: a 2x3 cluster with a single cell above the center of the bottom row. So shape like a small cluster.

Input cluster 2: R cluster. R cells: row7 col6-8. So shape: a horizontal line of 3 cells.

Now output cluster positions:

W cluster: output W cells: row2 col2, row3 col1-3. So shape same: row2 col2, row3 col1-3. So the cluster moved up by 4 rows? Let's check: original W cluster had min row 6, max row 7. Output W cluster has min row 2, max row 3. So moved up by 4 rows. The shape remains same relative arrangement: the relative positions of cells within cluster remain same: the top cell at row6 col2 moved to row2 col2 (difference -4). The bottom row cells at row7 col1-3 moved to row3 col1-3 (difference -4). So cluster moved up by 4 rows.

R cluster: input R cells: row7 col6-8. Output R cells: row4 col6-8. So moved up by 3 rows. Wait difference: row7 to row4 difference -3. So cluster moved up by 3 rows.

So clusters moved upward by different amounts. Why? The description: "the more roots in its mass, the taller it grows." So maybe the cluster with more cells (roots) moves up more? Let's check: W cluster has 4 cells. R cluster has 3 cells. W cluster moved up 4 rows, R cluster moved up 3 rows. That matches: number of cells equals number of rows moved up. So rule: each cluster moves upward by a number of rows equal to the number of cells in the cluster. That seems plausible.

But we need to confirm with other examples. We only have one training example. But we can test this rule on the test input.

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A small stage with nine positions arranged in a square — some occupied by performers in colored costumes, others left dark and empty. Each performer is a distinct voice in the ensemble. What to do: The more voices present in the choir, the more space each one claims. Every performer swells in presence proportional to the total number of singers — as if each voice resonates with every other, amplifying itself. The empty seats swell too, but remain silent darkness. The chorus arranges itself exactly as they stood on the original stage, just grander. Grid details: The intimate 3×3 rehearsal stage becomes a full concert hall. Each performer's single seat blooms into a square throne whose size is dictated by the richness of the ensemble — a solo act barely grows, but a quintet commands enormous territory. The darkness between performers expands in kind, a respectful silence scaled to match the music."

We have training example 1: Input 3x3 grid, output 9x9 grid. The transformation seems to be scaling each cell into a block of size equal to number of distinct colors? Let's analyze.

Input Example 1:
Row1: . A .
Row2: . M M
Row3: W A .

So 3x3 grid. Output is 9x9 grid. Let's examine output:

Output:
. . . A A A . . .
. . . A A A . . .
. . . A A A . . .
. . . M M M M M M
. . . M M M M M M
. . . M M M M M M
W W W A A A . . .
W W W A A A . . .
W W W A A A . . .

We can see that each input cell is expanded into a 3x3 block? Let's check: Input cell (1,1) is '.' (black). In output, the top-left 3x3 block is all '.'? Let's see: Output rows 1-3, columns 1-3: all '.'? Yes, output row1 col1-3: . . . ; row2 col1-3: . . . ; row3 col1-3: . . . . So yes, '.' expands to 3x3 block of '.'.

Input cell (1,2) is 'A'. In output, the block at rows 1-3, columns 4-6: all 'A'? Let's check: row1 col4-6: A A A ; row2 col4-6: A A A ; row3 col4-6: A A A. Yes.

Input cell (1,3) is '.' again, so block rows 1-3, columns 7-9: all '.'.

Input cell (2,1) is '.' -> block rows 4-6, columns 1-3: all '.'? Let's check: row4 col1-3: . . . ; row5 col1-3: . . . ; row6 col1-3: . . . . Yes.

Input cell (2,2) is 'M' -> block rows 4-6, columns 4-6: all 'M'? Let's check: row4 col4-6: M M M ; row5 col4-6: M M M ; row6 col4-6: M M M. Yes.

Input cell (2,3) is 'M' -> block rows 4-6, columns 7-9: all 'M'? Let's check: row4 col7-9: M M M ; row5 col7-9: M M M ; row6 col7-9: M M M. Yes.

Input cell (3,1) is 'W' -> block rows 7-9, columns 1-3: all 'W'? Let's check: row7 col1-3: W W W ; row8 col1-3: W W W ; row9 col1-3: W W W. Yes.

Input cell (3,2) is 'A' -> block rows 7-9, columns 4-6: all 'A'? Yes.

Input cell (3,3) is '.' -> block rows 7-9, columns 7-9: all '.'? Yes.

So the transformation is simply scaling each cell into a block of size equal to the number of distinct colors? Wait, but the scaling factor is 3. The input grid is 3x3, output is 9x9. So scaling factor is 3. But why 3? The description says: "The more voices present in the choir, the more space each one claims. Every performer swells in presence proportional to the total number of singers — as if each voice resonates with every other, amplifying itself. The empty seats swell too, but remain silent darkness. The chorus arranges itself exactly as they stood on the original stage, just grander. Grid details: The intimate 3×3 rehearsal stage becomes a full concert hall. Each performer's single seat blooms into a square throne whose size is dictated by the richness of the ensemble — a solo act barely grows, but a quintet commands enormous territory. The darkness between performers expands in kind, a respectful silence scaled to match the music."

So the scaling factor is the number of distinct colors? Let's check: In input example 1, distinct colors: '.' (black), 'A', 'M', 'W'. That's 4 distinct colors. But scaling factor is 3. So not that.

Maybe scaling factor is the number of non-empty cells? Let's count: Input has '.' at positions: (1,1), (1,3), (2,1), (3,3). That's 4 empty cells. Non-empty cells: (1,2) 'A', (2,2) 'M', (2,3) 'M', (3,1) 'W', (3,2) 'A'. That's 5 non-empty cells. So scaling factor 3 is not that.

Maybe scaling factor is the number of distinct colors minus 1? 4-1=3. That matches. But is that a coincidence? Let's test with other training examples. We only have one training example. But we can analyze the test input: . B . / . A O / W W . We need to produce output. We need to deduce the rule.

Let's analyze the test input: 3x3 grid:

Row1: . B .
Row2: . A O
Row3: W W .

We need to produce output grid. According to the rule, we might scale each cell into a block of size equal to something. The scaling factor might be the number of distinct colors minus 1? Let's compute distinct colors: '.' (black), 'B', 'A', 'O', 'W'. That's 5 distinct colors. Distinct colors minus 1 = 4. So scaling factor might be 4. That would produce a 12x12 output grid.

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A petri dish of colored organisms scattered among empty medium, each species distinct. What to do: Each organism replicates itself into a colony whose size reflects the biodiversity of the dish — the richer the ecosystem, the larger every colony swells. Grid details: The dish scales outward uniformly; empty medium expands in lockstep with living colonies, preserving the original spatial arrangement of the culture."

We have training example 1: Input grid 3x3? Let's parse.

Example 1 Input:
```
. A .
. M M
W A .
```
So 3 rows, 3 columns. '.' is black? Actually '.' is black. Colors: B=blue, R=red, G=green, Y=yellow, X=grey, M=magenta, O=orange, A=azure, W=maroon. '.' is black.

So input grid:

Row1: . A .
Row2: . M M
Row3: W A .

Output grid is 9x9? Let's examine.

Output:
```
. . . A A A . . .
. . . A A A . . .
. . . A A A . . .
. . . M M M M M M
. . . M M M M M M
. . . M M M M M M
W W W A A A . . .
W W W A A A . . .
W W W A A A . . .
```
So output grid is 9x9. So transformation: each cell in input expands to a 3x3 block? Let's check.

Input cell (1,1) is '.' (black). In output, top-left 3x3 block is all '.'? Let's see output rows 1-3, columns 1-3: all '.'? Output row1 col1-3: . . . ; row2 col1-3: . . . ; row3 col1-3: . . . . Yes, all '.'.

Input cell (1,2) is 'A'. In output, top-left 3x3 block? Actually the block for (1,2) would be rows 1-3, columns 4-6. Let's check: output rows 1-3, columns 4-6: A A A ; A A A ; A A A. Yes, all 'A'.

Input cell (1,3) is '.'; output rows 1-3, columns 7-9: . . . ; . . . ; . . . . Yes.

Input cell (2,1) is '.'; output rows 4-6, columns 1-3: . . . ; . . . ; . . . . Yes.

Input cell (2,2) is 'M'; output rows 4-6, columns 4-6: M M M ; M M M ; M M M. Yes.

Input cell (2,3) is 'M'; output rows 4-6, columns 7-9: M M M ; M M M ; M M M. Yes.

Input cell (3,1) is 'W'; output rows 7-9, columns 1-3: W W W ; W W W ; W W W. Yes.

Input cell (3,2) is 'A'; output rows 7-9, columns 4-6: A A A ; A A A ; A A A. Yes.

Input cell (3,3) is '.'; output rows 7-9, columns 7-9: . . . ; . . . ; . . . . Yes.

So transformation: each cell expands to a 3x3 block of the same color. So scaling factor 3. But the description says "Each organism replicates itself into a colony whose size reflects the biodiversity of the dish — the richer the ecosystem, the larger every colony swells. Grid details: The dish scales outward uniformly; empty medium expands in lockstep with living colonies, preserving the original spatial arrangement of the culture." That seems to match: each cell replicates into a colony of size equal to the number of distinct colors? Wait, "size reflects the biodiversity of the dish — the richer the ecosystem, the larger every colony swells." But in example, all colonies are same size 3x3. So maybe the size is constant? But the description might be generic. But we need to deduce rule: scaling factor maybe equal to number of distinct colors? Let's check: In example 1, distinct colors: '.' (black), 'A', 'M', 'W' => 4 distinct colors. But scaling factor is 3, not 4. So maybe scaling factor is number of distinct colors minus 1? 4-1=3. That matches. But we need to test with other examples. But we only have one training example. But maybe there are more training examples? The problem statement only shows Example 1. But maybe there are more hidden? Let's read again: "## Training Examples

Example 1:
Input:
. A .
. M M
W A .
Output:
...".

So only one training example. But we might need to deduce rule from that. But we also have test input: 
```
. B .
. A O
W W .
```
We need to produce output grid. We need to figure scaling factor. Let's analyze test input: 3x3 grid again. Distinct colors: '.' (black), 'B', 'A', 'O', 'W' => 5 distinct colors. So scaling factor might be 4? Or maybe 5? Let's examine description: "Each organism replicates itself into a colony whose size reflects the biodiversity of the dish — the richer the ecosystem, the larger every colony swells." So maybe colony size equals number of distinct colors? But in example 1, distinct colors 4, colony size 3. So not equal. Maybe colony size equals number of distinct colors minus 1? That would be 3. That matches. But why minus 1? Because maybe empty medium '.' is not counted? But '.' is empty medium. So maybe biodiversity refers to living organisms only, not empty medium. In example 1, living colors: 'A', 'M', 'W' => 3 distinct colors. Colony size 3. That matches. So scaling factor equals number of distinct living colors. That seems plausible. Let's test: In example 1, living colors: 'A', 'M', 'W' => 3. So scaling factor 3. In test input, living colors: 'B', 'A', 'O', 'W' => 4 distinct colors. So scaling factor 4. So output grid would be 3x3 input scaled by factor 4 => 12x12 output grid. But we need to confirm that scaling factor is indeed number of distinct living colors. Let's examine description: "Each or

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A small star chart with colored celestial objects and dark void between them. What to do: Each object and each void region expands into a square zone proportional to the count of distinct luminaries in the chart. Grid details: The star chart scales uniformly outward, preserving the original constellation pattern as each point becomes a block."

We have training example 1: Input grid 3x3? Let's examine.

Input:
. A .
. M M
W A .

So 3 rows, 3 columns. Represented as:

Row1: . A .
Row2: . M M
Row3: W A .

Output grid: 9x9? Let's examine output:

. . . A A A . . .
. . . A A A . . .
. . . A A A . . .
. . . M M M M M M
. . . M M M M M M
. . . M M M M M M
W W W A A A . . .
W W W A A A . . .
W W W A A A . . .

So output is 9x9. Each input cell expands into a 3x3 block? Let's check: Input cell at (1,1) is '.' (black). In output, the top-left 3x3 block is all '.'? Let's see: Output rows 1-3, columns 1-3: all '.'? Yes, first 3 rows, first 3 columns: all '.'.

Input cell at (1,2) is 'A' (azure). In output, the block at rows 1-3, columns 4-6: all 'A'? Yes, all 'A'.

Input cell at (1,3) is '.' again. Output block rows 1-3, columns 7-9: all '.'? Yes.

Input cell at (2,1) is '.' again. Output block rows 4-6, columns 1-3: all '.'? Wait, output rows 4-6, columns 1-3: all '.'? Let's check: rows 4-6, columns 1-3: all '.'? The output shows row4: . . . M M M M M M. So columns 1-3 are '.'? Yes, row4 columns 1-3: '.' '.' '.'. Row5: . . . M M M M M M. Row6: . . . M M M M M M. So yes, '.'.

Input cell at (2,2) is 'M' (magenta). Output block rows 4-6, columns 4-6: all 'M'? Let's check: row4 columns 4-6: M M M. Row5: M M M. Row6: M M M. Yes.

Input cell at (2,3) is 'M' again. Output block rows 4-6, columns 7-9: all 'M'? Row4 columns 7-9: M M M. Row5: M M M. Row6: M M M. Yes.

Input cell at (3,1) is 'W' (maroon). Output block rows 7-9, columns 1-3: all 'W'? Row7: W W W A A A . . . So columns 1-3: W W W. Row8: W W W. Row9: W W W. Yes.

Input cell at (3,2) is 'A'. Output block rows 7-9, columns 4-6: all 'A'? Row7 columns 4-6: A A A. Row8: A A A. Row9: A A A. Yes.

Input cell at (3,3) is '.' again. Output block rows 7-9, columns 7-9: all '.'? Row7 columns 7-9: . . . Row8: . . . Row9: . . . Yes.

So the transformation is: each input cell expands into a block of size N x N, where N is the number of distinct colors in the input grid? Wait, the description: "Each object and each void region expands into a square zone proportional to the count of distinct luminaries in the chart." The count of distinct luminaries in the chart: In the input, distinct colors: '.' (black), 'A', 'M', 'W'. That's 4 distinct colors. But the block size is 3x3, not 4x4. So maybe it's the number of distinct colors minus 1? Or maybe it's the number of distinct colors minus 1? Let's check: 4 distinct colors, minus 1 = 3. That matches block size 3. But is that always? Let's test with other examples.

We only have one training example. But we need to deduce the rule. The description: "Each object and each void region expands into a square zone proportional to the count of distinct luminaries in the chart." So each cell expands into a square zone whose side length is equal to the number of distinct luminaries? But we saw 4 distinct luminaries, but block size is 3. So maybe the count of distinct luminaries is 3? Let's count distinct luminaries: maybe they consider only colored objects, not black? The black '.' might be considered void, not a luminary. So distinct luminaries: 'A', 'M', 'W' = 3. That matches block size 3. So the rule: block size = number of distinct colored cells (excluding black). That seems plausible.

Also, the transformation preserves the pattern: each cell becomes a block of that size, with the same color. So the output grid is input grid scaled by factor N, where N = number of distinct colors (excluding black). That matches the example.

Now we need to apply to test input:

Test Input:
. B .
. A O
W W .

Let's parse: 3x3 grid.

Row1: . B .
Row2: . A O
Row3: W W .

Colors: '.' (black), 'B' (blue), 'A' (azure), 'O' (orange), 'W' (maroon). Distinct colored cells: B, A, O, W = 4 distinct colors. So N = 4. So output grid will be 12x12 (3*4 = 12). Each input cell expands into a 4x4 block of its color.

Let's confirm: In example, N=3, output 9x9. So yes.

Thus output grid: 12 rows, each row 12 columns. We need to fill each 4x4 block accordingly.

Let's map input coordinates to output coordinates.

Input grid coordinates (row, col) 1-indexed:

(1,1) = '.' -> block rows 1-4, cols 1-4: all '.'.

(1,2) = 'B' -> block rows 1-4, cols 5-8: all 'B'.

(1,3) = '.' -> block rows 1-4, cols 9-12: all '.'.

(2,1) = '.' -> block rows 5-8, cols 1-4: all '.'.

(2,2) = 'A' -> block rows 5-8, cols 5-8: all 'A'.

(2,3) = 'O' -> block rows 5-8, cols 9-12: all 'O'.

(3,1) = 'W' -> block rows 9-12, cols 1-4: all 'W'.

(3,2) = 'W' -> block rows 9-12, cols 5-8: all

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A small harbor chart with colored vessels and open water. What to do: Every ship and every stretch of open water swells into a square berth whose size matches the number of distinct flags flying in the harbor. Grid details: The harbor chart scales uniformly, each original position expanding into a square block while preserving the fleet's formation."

We have training example 1: Input grid 3x3? Let's parse.

Example 1 Input:
```
. A .
. M M
W A .
```
So 3 rows, 3 columns. '.' is black? Actually '.' is black. Colors: B=blue, R=red, G=green, Y=yellow, X=grey, M=magenta, O=orange, A=azure, W=maroon. '.' is black.

So input grid:

Row1: . A .
Row2: . M M
Row3: W A .

Output grid:
```
. . . A A A . . .
. . . A A A . . .
. . . A A A . . .
. . . M M M M M M
. . . M M M M M M
. . . M M M M M M
W W W A A A . . .
W W W A A A . . .
W W W A A A . . .
```
So output grid is 9x9? Let's count columns: The first row: ". . . A A A . . ." that's 9 columns. So output is 9x9. So each input cell expands into a 3x3 block? Let's check: Input grid 3x3, output 9x9. So each cell expands into a 3x3 block. But the output shows that each cell's color is expanded into a 3x3 block of that color? Let's check.

Input cell (1,1) is '.' (black). Output block at top-left 3x3: all '.'? Let's check output first 3 rows, first 3 columns: Row1: . . . ; Row2: . . . ; Row3: . . . . Yes, all '.'.

Input cell (1,2) is 'A' (azure). Output block at top-left 3x3? Actually the block for (1,2) would be columns 4-6, rows 1-3. Let's check: Row1 columns 4-6: A A A ; Row2: A A A ; Row3: A A A. Yes, all 'A'.

Input cell (1,3) is '.' again. Output block at columns 7-9, rows 1-3: all '.'.

Input cell (2,1) is '.' again. Output block at rows 4-6, columns 1-3: all '.'? Let's check: Row4 columns 1-3: . . . ; Row5: . . . ; Row6: . . . . Yes.

Input cell (2,2) is 'M' (magenta). Output block at rows 4-6, columns 4-6: all 'M'? Let's check: Row4 columns 4-6: M M M ; Row5: M M M ; Row6: M M M. Yes.

Input cell (2,3) is 'M' again. Output block at rows 4-6, columns 7-9: all 'M'? Let's check: Row4 columns 7-9: M M M ; Row5: M M M ; Row6: M M M. Yes.

Input cell (3,1) is 'W' (maroon). Output block at rows 7-9, columns 1-3: all 'W'? Let's check: Row7 columns 1-3: W W W ; Row8: W W W ; Row9: W W W. Yes.

Input cell (3,2) is 'A' again. Output block at rows 7-9, columns 4-6: all 'A'? Row7 columns 4-6: A A A ; Row8: A A A ; Row9: A A A. Yes.

Input cell (3,3) is '.' again. Output block at rows 7-9, columns 7-9: all '.'? Row7 columns 7-9: . . . ; Row8: . . . ; Row9: . . . . Yes.

So the transformation is: each input cell expands into a square block of size equal to the number of distinct colors in the input? Wait, the description says: "Every ship and every stretch of open water swells into a square berth whose size matches the number of distinct flags flying in the harbor." So the size of each block is equal to the number of distinct flags (colors) in the input grid. In example 1, the input grid has colors: '.' (black), 'A', 'M', 'W'. That's 4 distinct colors. But the block size is 3x3, not 4x4. Wait, maybe '.' is not considered a flag? The description says "flags flying in the harbor" maybe only colored vessels? But '.' is black, maybe representing water. So maybe only colored cells count. Let's check: Input colors: 'A', 'M', 'W' (3 distinct). So block size is 3x3. That matches. So the rule: For each cell in input, expand into a square block of size equal to the number of distinct non-'.' colors in the input. Each block is filled with the same color as the original cell. The output grid is thus input size times block size.

But we need to confirm with the test input. The test input is:

```
. B .
. A O
W W .
```

Let's parse: 3x3 grid.

Row1: . B .
Row2: . A O
Row3: W W .

Colors present: '.' (black), 'B', 'A', 'O', 'W'. Distinct non-'.' colors: 'B', 'A', 'O', 'W' => 4 distinct colors. So block size should be 4x4. So output grid should be 12x12? Wait, input 3x3, block size 4, output 12x12. Let's confirm: 3*4 = 12. So output grid 12x12.

But we need to confirm that the rule is indeed that each cell expands into a block of size equal to the number of distinct non-'.' colors. Let's double-check with the example: Input had 3 distinct non-'.' colors: 'A', 'M', 'W'. So block size 3. Yes. So rule holds.

But we need to confirm that the output grid is exactly that: each cell expands into a block of that size, preserving the arrangement. The output grid in example 1 is exactly that.

Thus for test input, we need to produce a 12x12 grid where each input cell expands into a 4x4 block of its color.

But we need to confirm that '.' cells also expand into blocks of '.'? Yes, in example 1, '.' cells expanded into '.' blocks. So we will do the same.

Thus we need to produce a 12x12 grid. Let's map each input cell to a 4x4 block.

Input grid coordinates:

(1,1) '.' -> 4x4 block of '.' at rows 1-

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A small PCB layout with colored components and empty pads. What to do: Each component and each empty pad scales into a square region whose side equals the number of unique part types on the board. Grid details: The PCB layout grows uniformly, maintaining the original component placement as every position becomes a larger square footprint."

We have training example 1: Input grid 3x3? Let's examine.

Example 1 Input:
```
. A .
. M M
W A .
```
So 3 rows, 3 columns. Colors: '.' black, 'A' azure, 'M' magenta, 'W' maroon.

Output grid:
```
. . . A A A . . .
. . . A A A . . .
. . . A A A . . .
. . . M M M M M M
. . . M M M M M M
. . . M M M M M M
W W W A A A . . .
W W W A A A . . .
W W W A A A . . .
```
So output grid is 9x9. Each input cell becomes a 3x3 block? Let's check: Input grid 3x3, output 9x9. So scaling factor is 3. That matches "side equals the number of unique part types on the board." Let's count unique part types: In input, we have '.' (black), 'A', 'M', 'W'. That's 4 unique types. But scaling factor is 3, not 4. Wait maybe they exclude '.'? Let's check: Unique part types maybe only colored components? But '.' is empty pad. The description: "Each component and each empty pad scales into a square region whose side equals the number of unique part types on the board." So includes empty pad. So number of unique part types is 4. But scaling factor is 3. So maybe they count only colored components? Let's count colored components: 'A', 'M', 'W' => 3 unique types. That matches scaling factor 3. So '.' is not counted as a part type? But the description says "each component and each empty pad scales into a square region". But maybe they treat '.' as empty pad but not counted as part type? But they say "unique part types on the board" maybe refers to colored components only. Let's examine training example 1: Input has 3 colored types: A, M, W. So scaling factor 3. Output 9x9. Each input cell becomes 3x3 block. Let's verify mapping: Input cell (0,0) '.' becomes output block of 3x3 '.'? Let's check output: top-left 3x3 block: rows 0-2, cols 0-2: all '.'? Output shows first 3 rows: first 3 columns are '.'? Let's check output: first row: ". . . A A A . . ." So first 3 columns are '.'? Yes. So '.' maps to 3x3 '.' block. Good.

Input cell (0,1) 'A' maps to 3x3 block of 'A'? Let's check output: top-left 3x3 block of 'A' should be at rows 0-2, cols 3-5. Output: first row: ". . . A A A . . ." So columns 3-5 are 'A'. Good. So mapping holds.

Input cell (0,2) '.' maps to 3x3 '.' block at rows 0-2, cols 6-8. Output: first row: ". . . A A A . . ." So columns 6-8 are '.'? Yes.

Input cell (1,0) '.' maps to 3x3 '.' block at rows 3-5, cols 0-2. Output: row 3: ". . . M M M M M M" Wait row 3: ". . . M M M M M M". So columns 0-2 are '.'? Yes. Good.

Input cell (1,1) 'M' maps to 3x3 'M' block at rows 3-5, cols 3-5. Output: row 3: ". . . M M M M M M" columns 3-5 are 'M'. Good.

Input cell (1,2) 'M' maps to 3x3 'M' block at rows 3-5, cols 6-8. Output: row 3: ". . . M M M M M M" columns 6-8 are 'M'. Good.

Input cell (2,0) 'W' maps to 3x3 'W' block at rows 6-8, cols 0-2. Output: row 6: "W W W A A A . . ." columns 0-2 are 'W'. Good.

Input cell (2,1) 'A' maps to 3x3 'A' block at rows 6-8, cols 3-5. Output: row 6: "W W W A A A . . ." columns 3-5 are 'A'. Good.

Input cell (2,2) '.' maps to 3x3 '.' block at rows 6-8, cols 6-8. Output: row 6: "W W W A A A . . ." columns 6-8 are '.'.

So transformation: scale each cell to a square of side equal to number of unique colored component types (excluding '.'), replicating the same color.

Thus the rule: Determine number of unique colors (excluding '.') in input grid. Let N = that number. Output grid is input grid scaled by factor N: each cell replaced by N x N block of same color.

Now test input: 
```
. B .
. A O
W W .
```
We need to compute unique colored component types: B, A, O, W. That's 4 unique colors. '.' is empty pad but not counted. So scaling factor N=4. Input grid is 3x3. Output grid will be 12x12 (3*4=12). Each input cell becomes 4x4 block of same color.

Let's verify with training example: They had 3 unique colors, scaling factor 3. Output 9x9. So yes.

Thus we need to produce 12x12 grid. Let's map each input cell to 4x4 block.

Input grid coordinates:

Row 0: col0 '.', col1 'B', col2 '.'
Row 1: col0 '.', col1 'A', col2 'O'
Row 2: col0 'W', col1 'W', col2 '.'

We need to produce output grid of 12 rows, each row 12 columns.

We can produce by constructing 4x4 blocks for each cell.

Let's define block for '.' is '.' repeated 4x4.

Block for 'B' is 'B' repeated 4x4.

Block for 'A' is 'A' repeated 4x4.

Block for 'O' is 'O' repeated 4x4.

Block for 'W' is 'W' repeated 4x4.

Now we need to place them in order.

The output grid will be arranged as:

Rows 0-3: correspond to input row 0. Each row 0-3 will have 3 blocks horizontally: block for col0 '.' (4 columns), block for col1 'B' (4 c

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A small celestial map with colored divine domains and primordial void. What to do: Each god's domain and each stretch of void expands into a square territory proportional to the number of distinct deities in the pantheon. Grid details: The cosmic map scales uniformly, each original position becoming a block, preserving the divine arrangement."

We have training example 1: Input grid 3x3? Let's parse.

Example 1 Input:
```
. A .
. M M
W A .
```
So 3 rows, 3 columns. '.' is black? Actually '.' is black. Colors: B=blue, R=red, G=green, Y=yellow, X=grey, M=magenta, O=orange, A=azure, W=maroon. '.' is black.

So input grid:
Row1: . A .
Row2: . M M
Row3: W A .

Output grid:
```
. . . A A A . . .
. . . A A A . . .
. . . A A A . . .
. . . M M M M M M
. . . M M M M M M
. . . M M M M M M
W W W A A A . . .
W W W A A A . . .
W W W A A A . . .
```
So output grid is 9x9? Let's count: Each row has 9 columns. Yes 9x9. So each input cell expanded into a 3x3 block? Let's check: Input 3x3, output 9x9. So scaling factor 3. Each input cell becomes a 3x3 block. But the pattern is not uniform: For example, input cell (1,1) is '.' (black). In output, the top-left 3x3 block is all '.'? Let's check: Output row1: . . . A A A . . . So first 3 columns are '.'? Yes. Row2: . . . A A A . . . So first 3 columns '.' again. Row3: . . . A A A . . . So first 3 columns '.' again. So top-left 3x3 block is all '.'.

Input cell (1,2) is 'A' (azure). In output, the block at rows 1-3, columns 4-6 is 'A A A' repeated. So that block is all 'A'. Good.

Input cell (1,3) is '.' again. In output, block at rows 1-3, columns 7-9 is '.' all. Good.

Input cell (2,1) is '.' again. Output block rows 4-6, columns 1-3 is '.'? Let's check row4: . . . M M M M M M. Wait row4: . . . M M M M M M. So first 3 columns '.'? Yes. Row5: . . . M M M M M M. Row6: . . . M M M M M M. So block rows 4-6, columns 1-3 is '.' all. Good.

Input cell (2,2) is 'M' (magenta). Output block rows 4-6, columns 4-6 is 'M M M'? Let's check row4: . . . M M M M M M. So columns 4-6 are M M M. Row5: same. Row6: same. So block is all 'M'.

Input cell (2,3) is 'M' again. Output block rows 4-6, columns 7-9 is 'M M M'? Let's check row4: . . . M M M M M M. So columns 7-9 are M M M. Row5: same. Row6: same. So block is all 'M'.

Input cell (3,1) is 'W' (maroon). Output block rows 7-9, columns 1-3 is 'W W W'? Let's check row7: W W W A A A . . . So columns 1-3 are W W W. Row8: same. Row9: same. Good.

Input cell (3,2) is 'A' again. Output block rows 7-9, columns 4-6 is 'A A A'? Row7: W W W A A A . . . So columns 4-6 are A A A. Row8: same. Row9: same. Good.

Input cell (3,3) is '.' again. Output block rows 7-9, columns 7-9 is '.'? Row7: W W W A A A . . . So columns 7-9 are . . . Good.

So the transformation is: Each input cell expands into a block of size N x N, where N is the number of distinct colors (deities) in the input? Wait the description: "Each god's domain and each stretch of void expands into a square territory proportional to the number of distinct deities in the pantheon." So each cell expands into a square block whose side length equals the number of distinct deities in the input. In example 1, distinct colors: '.' (black), 'A', 'M', 'W'. That's 4 distinct colors. But the scaling factor is 3, not 4. Wait maybe '.' is not counted? Or maybe they count only colored cells? Let's check: Distinct deities: A, M, W. That's 3. So scaling factor 3. That matches. So '.' is void, not a deity. So the number of distinct deities (colored cells) is 3. So each cell expands into a 3x3 block. That matches.

Thus transformation rule: Determine the number of distinct colors (excluding '.') in the input grid. Let N = that number. Then output grid is input grid scaled by factor N: each cell replaced by an N x N block of the same color. The arrangement is preserved.

Now test input: 
```
. B .
. A O
W W .
```
We need to compute distinct colors (excluding '.') in this grid. Colors present: B, A, O, W. That's 4 distinct colors. So scaling factor N = 4. So output grid will be 4x4 blocks for each input cell, resulting in 12x12 grid? Wait input grid is 3x3, scaling factor 4 => output grid 12x12. Yes.

We need to produce the output grid: 12 rows, each with 12 characters separated by spaces. Each input cell replaced by a 4x4 block of that color.

Let's confirm with example: In example 1, scaling factor 3, output grid 9x9. Yes.

So for test input, we produce 12x12 grid.

Let's map input coordinates:

Input grid coordinates (row, col):
Row1: col1 '.', col2 'B', col3 '.'
Row2: col1 '.', col2 'A', col3 'O'
Row3: col1 'W', col2 'W', col3 '.'

We need to produce output grid rows 1-12, columns 1-12.

We can think of each input cell mapping to a block of 4 rows and 4 columns.

Block mapping:

- Input cell (1,1) '.' => block rows 1-4, cols 1-4 all '.'.
- Input cell (1,2) 'B' => block rows 1-4, cols 5-8 all 'B'.
- Input cell (1

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A small geological cross-section with colored mineral deposits and barren rock. What to do: Each mineral deposit and each barren zone grows into a square crystal whose dimensions match the number of distinct minerals in the sample. Grid details: The cross-section scales uniformly, preserving the original stratigraphy as every position expands into a square block."

We have training example 1: Input grid 3x3? Let's parse.

Example 1 Input:
```
. A .
. M M
W A .
```
So 3 rows, 3 columns. '.' is black? Actually '.' is black. Colors: B=blue, R=red, G=green, Y=yellow, X=grey, M=magenta, O=orange, A=azure, W=maroon. '.' is black.

So input grid:

Row1: . A .
Row2: . M M
Row3: W A .

Output grid:
```
. . . A A A . . .
. . . A A A . . .
. . . A A A . . .
. . . M M M M M M
. . . M M M M M M
. . . M M M M M M
W W W A A A . . .
W W W A A A . . .
W W W A A A . . .
```
So output grid is 9x9? Let's count: Each row has 9 characters. Yes 9x9.

So transformation: Each cell in input expands into a square block of size equal to number of distinct minerals in the sample. Distinct minerals: In input, we have colors: '.' (black), 'A', 'M', 'W'. That's 4 distinct colors. So each cell expands into a 4x4 block? Wait output block size: For each input cell, we see a 3x3 block? Let's examine.

Input cell (1,1) is '.' (black). In output, the top-left 3x3 block? Let's check output row1: ". . . A A A . . ." So first 3 columns are '.'? Actually row1: . . . A A A . . . So first 3 columns are '.'? Yes. Row2: . . . A A A . . . So first 3 columns are '.' again. Row3: . . . A A A . . . So first 3 columns are '.' again. So the top-left 3x3 block is all '.'.

So each input cell expands into a 3x3 block. But we expected 4x4? Let's check other cells.

Input cell (1,2) is 'A'. In output, the block at columns 4-6, rows 1-3: A A A repeated. So 3x3 block of 'A'.

Input cell (1,3) is '.' again. In output, columns 7-9, rows 1-3: . . . So 3x3 block of '.'.

Input cell (2,1) is '.' again. In output, rows 4-6, columns 1-3: . . .? Let's check row4: . . . M M M M M M. Wait row4: . . . M M M M M M. So first 3 columns are '.'? Actually row4: . . . M M M M M M. So first 3 columns are '.'? Yes. Row5: . . . M M M M M M. Row6: . . . M M M M M M. So rows 4-6, columns 1-3 are '.'.

Input cell (2,2) is 'M'. In output, rows 4-6, columns 4-6: M M M. So 3x3 block of 'M'.

Input cell (2,3) is 'M'. In output, rows 4-6, columns 7-9: M M M. So 3x3 block of 'M'.

Input cell (3,1) is 'W'. In output, rows 7-9, columns 1-3: W W W. So 3x3 block of 'W'.

Input cell (3,2) is 'A'. In output, rows 7-9, columns 4-6: A A A. So 3x3 block of 'A'.

Input cell (3,3) is '.' again. In output, rows 7-9, columns 7-9: . . . So 3x3 block of '.'.

Thus each input cell expands into a 3x3 block. So the scaling factor is 3. But the description says "Each mineral deposit and each barren zone grows into a square crystal whose dimensions match the number of distinct minerals in the sample." Distinct minerals: 4. But scaling factor is 3. So maybe the number of distinct minerals is 3? Wait we counted 4 distinct colors: '.' (black), 'A', 'M', 'W'. But maybe '.' is not considered a mineral deposit? The description says "mineral deposit and each barren zone grows into a square crystal". So maybe '.' is considered barren zone. So distinct minerals might be only the colored minerals, not including '.'? Let's check: Colors present: 'A', 'M', 'W'. That's 3 distinct minerals. So scaling factor is 3. That matches output. So the rule: Count distinct colored minerals (excluding '.'), call that N. Then each cell expands into an N x N block of the same color. So each cell expands uniformly.

Thus transformation: For each cell in input, produce an N x N block of that cell's color. The output grid will be N times larger in each dimension: input size m x n -> output size (m*N) x (n*N). The output preserves the original stratigraphy: each cell expands into a block.

Now we need to apply to test input:

Test Input:
```
. B .
. A O
W W .
```
Let's parse: 3 rows, 3 columns.

Row1: . B .
Row2: . A O
Row3: W W .

Colors: '.' (black), 'B', 'A', 'O', 'W'. Distinct colored minerals: B, A, O, W. That's 4 distinct minerals. So N=4. So each input cell expands into a 4x4 block.

Thus output grid will be 12x12 (3*4=12). We need to produce 12 rows, each with 12 characters.

We need to produce the output grid accordingly.

Let's confirm with training example: Input had 3 distinct colored minerals: A, M, W. So N=3. Output 9x9. Yes.

Thus rule: Count distinct colored minerals (excluding '.'), N. Expand each cell into N x N block of same color.

Now we need to produce output for test input.

Test Input grid:

Row1: . B .
Row2: . A O
Row3: W W .

Let's index cells:

(1,1) '.' (black)
(1,2) 'B'
(1,3) '.'
(2,1) '.'
(2,2) 'A'
(2,3) 'O'
(3,1) 'W'
(3,2) 'W'

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A sparse arrangement of ingredients resting on a neutral surface, some spaces left bare. What to do: Each ingredient puffs up into a generous portion proportional to how many distinct flavors share the recipe, while bare spaces become equally generous servings of nothing. Grid details: The cutting board grows to accommodate every inflated ingredient, each occupying a square region, preserving the original mise en place layout."

We have training example 1: Input grid 3x3? Let's parse.

Input:
. A .
. M M
W A .

So grid 3 rows, 3 columns. Represented as:

Row1: . A .
Row2: . M M
Row3: W A .

Output grid: Let's parse the output lines:

. . . A A A . . .
. . . A A A . . .
. . . A A A . . .
. . . M M M M M M
. . . M M M M M M
. . . M M M M M M
W W W A A A . . .
W W W A A A . . .
W W W A A A . . .

So output grid is 9x9? Let's count columns: The first line: ". . . A A A . . ." That's 9 columns. So output grid is 9x9. So each input cell expands to a 3x3 block? Let's check: Input 3x3, output 9x9. So each input cell expands to 3x3 block. But the output shows that each cell is expanded to a 3x3 block of the same color? Let's examine.

Input cell (1,1) is '.' (black). Output block at top-left 3x3: first 3 rows, first 3 columns: all '.'? Let's check: first line: ". . . A A A . . ." first 3 columns are '.' '.' '.' yes. second line: ". . . A A A . . ." first 3 columns '.' '.' '.' yes. third line: ". . . A A A . . ." first 3 columns '.' '.' '.' yes. So that block is all '.'.

Input cell (1,2) is 'A'. Output block at top-left 3x3? Actually the block for (1,2) would be columns 4-6, rows 1-3. Let's check: first line columns 4-6: "A A A" yes. second line: "A A A" yes. third line: "A A A" yes. So block is all 'A'.

Input cell (1,3) is '.' again. Output block at columns 7-9, rows 1-3: all '.'? Let's check: first line columns 7-9: ". . ." yes. second line: ". . ." yes. third line: ". . ." yes.

Input cell (2,1) is '.' again. Output block at rows 4-6, columns 1-3: all '.'? Let's check: row4: ". . . M M M M M M" first 3 columns '.' '.' '.' yes. row5: same. row6: same. So block is all '.'.

Input cell (2,2) is 'M'. Output block at rows 4-6, columns 4-6: "M M M" each row? Let's check: row4 columns 4-6: "M M M" yes. row5: "M M M" yes. row6: "M M M" yes.

Input cell (2,3) is 'M'. Output block at rows 4-6, columns 7-9: "M M M" each row? Let's check: row4 columns 7-9: "M M M" yes. row5: "M M M" yes. row6: "M M M" yes.

Input cell (3,1) is 'W'. Output block at rows 7-9, columns 1-3: "W W W" each row? Let's check: row7: "W W W A A A . . ." first 3 columns "W W W" yes. row8: same. row9: same.

Input cell (3,2) is 'A'. Output block at rows 7-9, columns 4-6: "A A A" each row? Let's check: row7 columns 4-6: "A A A" yes. row8: same. row9: same.

Input cell (3,3) is '.' again. Output block at rows 7-9, columns 7-9: all '.'? Let's check: row7 columns 7-9: ". . ." yes. row8: same. row9: same.

So the transformation is: each input cell expands to a 3x3 block of the same color. So the output grid is 3 times larger in each dimension. But the description says: "Each ingredient puffs up into a generous portion proportional to how many distinct flavors share the recipe, while bare spaces become equally generous servings of nothing." That might refer to scaling factor equal to number of distinct colors? Wait, but in example 1, scaling factor is 3. But why 3? Let's examine the input: distinct colors present: '.' (black), 'A', 'M', 'W'. That's 4 distinct colors. But scaling factor is 3, not 4. So maybe scaling factor is number of distinct colors minus 1? That would be 3. But that seems arbitrary.

Alternatively, maybe scaling factor is the number of distinct colors that are not '.'? That would be 3 (A, M, W). That matches scaling factor 3. But the description says "proportional to how many distinct flavors share the recipe". That might refer to number of distinct colors in the input? But we need to confirm with other examples.

We only have one training example. But we need to apply to test input: 
Test Input:
. B .
. A O
W W .

We need to produce output grid. We need to deduce scaling factor. Let's analyze test input: Input grid 3x3 again. Colors present: '.' (black), 'B', 'A', 'O', 'W'. Distinct colors: '.' (black), 'B', 'A', 'O', 'W' => 5 distinct colors. But maybe scaling factor is number of distinct non-'.' colors: 'B', 'A', 'O', 'W' => 4. So scaling factor might be 4. But we need to confirm with training example: In training example, distinct non-'.' colors: 'A', 'M', 'W' => 3. So scaling factor 3. That matches. So scaling factor = number of distinct non-'.' colors in input. That seems plausible.

But we need to confirm that the output grid is indeed scaling factor times larger in each dimension. In training example, scaling factor 3, output grid 9x9. Input 3x3. So 3*3=9. So yes.

Now we need to confirm that each cell expands to a block of siz

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: Athletes and empty patches scattered across a small playing field. What to do: Each player stakes out a square territory whose size reflects the total number of teams competing; unoccupied zones grow by the same proportion. Grid details: The field expands uniformly, each original position becoming a block, maintaining the spatial formation of the original lineup."

We have training example 1: Input grid 3x3? Let's examine.

Example 1 Input:
```
. A .
. M M
W A .
```
So 3 rows, 3 columns. Output grid is 9x9? Let's check. Output:

```
. . . A A A . . .
. . . A A A . . .
. . . A A A . . .
. . . M M M M M M
. . . M M M M M M
. . . M M M M M M
W W W A A A . . .
W W W A A A . . .
W W W A A A . . .
```

That's 9 rows, 9 columns. So the transformation expands each cell into a 3x3 block? Let's check: Input cell (0,0) is '.' (black). In output, the top-left 3x3 block is all '.'? Let's see: Output rows 0-2, columns 0-2: all '.'? Yes, first 3 rows, first 3 columns: all '.'.

Input cell (0,1) is 'A' (azure). In output, the block at rows 0-2, columns 3-5: all 'A'? Yes, rows 0-2, columns 3-5: all 'A'.

Input cell (0,2) is '.' again. Output block rows 0-2, columns 6-8: all '.'? Yes.

Input cell (1,0) is '.' again. Output block rows 3-5, columns 0-2: all '.'? Wait, output rows 3-5, columns 0-2: all '.'? Let's check: row 3: ". . . M M M M M M" -> columns 0-2 are '.'? Yes. Row 4: same. Row 5: same. So yes.

Input cell (1,1) is 'M' (magenta). Output block rows 3-5, columns 3-5: all 'M'? Let's check: row 3: ". . . M M M M M M" -> columns 3-5 are 'M'? Yes. Row 4: same. Row 5: same.

Input cell (1,2) is 'M' again. Output block rows 3-5, columns 6-8: all 'M'? Let's check: row 3: columns 6-8 are 'M'? Yes. Row 4: same. Row 5: same.

Input cell (2,0) is 'W' (maroon). Output block rows 6-8, columns 0-2: all 'W'? Let's check: row 6: "W W W A A A . . ." -> columns 0-2 are 'W'? Yes. Row 7: same. Row 8: same.

Input cell (2,1) is 'A'. Output block rows 6-8, columns 3-5: all 'A'? Yes. Row 6: columns 3-5 are 'A'? Yes. Row 7: same. Row 8: same.

Input cell (2,2) is '.' again. Output block rows 6-8, columns 6-8: all '.'? Yes.

So the transformation is: each cell expands into a 3x3 block of the same color. So the scaling factor is 3. But the description says "Each player stakes out a square territory whose size reflects the total number of teams competing; unoccupied zones grow by the same proportion. Grid details: The field expands uniformly, each original position becoming a block, maintaining the spatial formation of the original lineup." That matches: each cell becomes a block of size equal to the number of teams? But we need to deduce the scaling factor from the input. In example 1, the input is 3x3, output is 9x9, scaling factor 3. That might be the number of distinct colors? Let's count distinct colors in input: '.' (black), 'A', 'M', 'W'. That's 4 distinct colors. But scaling factor is 3, not 4. Maybe it's the number of non-empty cells? Let's count non-empty cells: 'A', 'M', 'M', 'W', 'A' = 5 non-empty cells. Not 3. Maybe it's the number of rows? Input has 3 rows, output has 9 rows, scaling factor 3. So scaling factor equals number of rows? But input is 3x3, so scaling factor equals number of rows (3). That seems plausible. But we need to confirm with other training examples. There's only one training example given. But the test input is also 3x3. So scaling factor might be 3 again. But we need to confirm if scaling factor is always equal to number of rows in input. But the description says "Each player stakes out a square territory whose size reflects the total number of teams competing; unoccupied zones grow by the same proportion." That might refer to the number of distinct colors (teams). But we need to parse the metaphor.

Let's parse the metaphor: "What you see: Athletes and empty patches scattered across a small playing field." So the input grid has colored cells representing athletes (players) and '.' representing empty patches. "What to do: Each player stakes out a square territory whose size reflects the total number of teams competing; unoccupied zones grow by the same proportion." So each player (colored cell) expands into a square territory. The size of the territory reflects the total number of teams competing. So the side length of the square territory might be equal to the number of distinct colors (teams). But in example 1, number of distinct colors is 4, but side length is 3. So maybe it's the number of distinct colors minus 1? That would be 3. But that seems arbitrary. Or maybe it's the number of distinct colors minus the number of empty cells? Let's check: distinct colors: 4. Number of empty cells: 4? Actually input has '.' at positions (0,0), (0,2), (1,0), (2,2). That's 4 empty cells. So distinct colors minus empty cells = 0. Not 3. So no.

Alternatively, maybe the side length equals the number of rows (or col

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A small forecast map with colored weather systems and calm patches. What to do: Each system — and each calm zone — inflates its area based on how many distinct fronts are present, as if mutual atmospheric pressure forces them all to swell equally. Grid details: The map scales uniformly outward, each original cell becoming a square region, preserving the original meteorological layout."

We have training example 1: Input grid 3x3? Let's parse.

Example 1 Input:
```
. A .
. M M
W A .
```
So 3 rows, 3 columns. Output grid is 9x9? Let's examine output:

```
. . . A A A . . .
. . . A A A . . .
. . . A A A . . .
. . . M M M M M M
. . . M M M M M M
. . . M M M M M M
W W W A A A . . .
W W W A A A . . .
W W W A A A . . .
```

So output is 9x9. Each input cell becomes a 3x3 block? Let's check: Input cell (0,0) is '.' (black). In output, top-left 3x3 block is all '.'? Let's see: first 3 rows, first 3 columns: all '.'? Output shows first 3 rows: first 3 columns are '.'? Let's check: Row1: ". . . A A A . . ." -> first 3 columns '.' '.' '.' yes. Row2: same. Row3: same. So yes, input cell '.' maps to 3x3 block of '.'.

Input cell (0,1) is 'A'. In output, the block at rows 0-2, columns 3-5 is 'A'? Let's check: Row1 columns 4-6? Wait indexing: columns 0-8. For block (0,1) we expect columns 3-5. Row1: ". . . A A A . . ." -> columns 3-5 are 'A A A'. Row2 same. Row3 same. So yes, 'A' maps to 3x3 block of 'A'.

Input cell (0,2) is '.' again -> block rows 0-2, columns 6-8 all '.'? Row1 columns 6-8: ". . ." yes.

Input cell (1,0) is '.' -> block rows 3-5, columns 0-2 all '.'? Let's check row4: ". . . M M M M M M" -> columns 0-2 are '.' '.' '.' yes. Row5 same. Row6 same.

Input cell (1,1) is 'M' -> block rows 3-5, columns 3-5 should be 'M'? Row4 columns 3-5: "M M M" yes. Row5 same. Row6 same.

Input cell (1,2) is 'M' -> block rows 3-5, columns 6-8 should be 'M'? Row4 columns 6-8: "M M M" yes.

Input cell (2,0) is 'W' -> block rows 6-8, columns 0-2 should be 'W'? Row7 columns 0-2: "W W W" yes.

Input cell (2,1) is 'A' -> block rows 6-8, columns 3-5 should be 'A'? Row7 columns 3-5: "A A A" yes.

Input cell (2,2) is '.' -> block rows 6-8, columns 6-8 all '.'? Row7 columns 6-8: ". . ." yes.

So the transformation is simply scaling each cell to a 3x3 block of the same color. That is a simple scaling by factor 3. But the description says "Each system — and each calm zone — inflates its area based on how many distinct fronts are present, as if mutual atmospheric pressure forces them all to swell equally." That might refer to scaling factor equal to number of distinct colors? But in example, scaling factor is 3. Let's examine number of distinct colors in input: '.' (black), 'A', 'M', 'W' => 4 distinct colors. But scaling factor is 3, not 4. Maybe scaling factor equals number of distinct colors minus 1? 4-1=3. But that seems arbitrary.

Alternatively, maybe scaling factor equals number of distinct colors in the entire grid? But we saw 4 distinct colors. But scaling factor 3. So maybe scaling factor equals number of distinct colors minus 1? Let's test with other examples? We only have one training example. But the description: "Each system — and each calm zone — inflates its area based on how many distinct fronts are present, as if mutual atmospheric pressure forces them all to swell equally." That could mean each cell expands to a square region whose side length equals the number of distinct colors in the grid. But we saw 4 distinct colors, but side length 3. So maybe it's number of distinct colors minus 1. But why minus 1? Maybe because the calm zone '.' is considered not a front? But '.' is a calm zone. The description says "Each system — and each calm zone — inflates its area based on how many distinct fronts are present". So maybe the number of distinct fronts is number of distinct colors excluding '.'? That would be 3 distinct fronts: 'A', 'M', 'W'. Then scaling factor 3. That matches. So scaling factor equals number of distinct non-'.' colors. That seems plausible.

Let's test: Input has '.' (calm zone) and three colored systems: 'A', 'M', 'W'. So number of distinct fronts = 3. So each cell expands to a 3x3 block. That matches.

Thus transformation rule: For each cell in input grid, produce a block of size N x N where N = number of distinct non-'.' colors in the input grid. Fill block with the same color as the input cell. The output grid will be N times larger in each dimension.

But we need to confirm that the output grid is exactly N times larger. In example, input 3x3, N=3, output 9x9. Yes.

Now we need to apply to test input:

Test Input:
```
. B .
. A O
W W .
```

Let's parse: 3 rows, 3 columns.

Row0: '.' 'B' '.'
Row1: '.' 'A' 'O'
Row2: 'W' 'W' '.'

We need to find number of distinct non-'.' colors: 'B', 'A', 'O', 'W' => 4 distinct colors. So N=4.

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A small floorplan with colored rooms and vacant lots arranged in a grid. What to do: Every room and every vacancy scales up its footprint equally, determined by how many distinct tenants occupy the building — more tenants, grander rooms for all. Grid details: The blueprint grows proportionally, each original unit becoming a square block, maintaining the spatial relationships of the original design."

We have training example 1: Input grid 3x3? Let's parse.

Example 1 Input:
```
. A .
. M M
W A .
```
So 3 rows, 3 columns. Output grid is 9x9? Let's examine output:

```
. . . A A A . . .
. . . A A A . . .
. . . A A A . . .
. . . M M M M M M
. . . M M M M M M
. . . M M M M M M
W W W A A A . . .
W W W A A A . . .
W W W A A A . . .
```

So output is 9x9. Each input cell becomes a 3x3 block? Let's check: Input cell (0,0) is '.' (black). In output, the top-left 3x3 block is all '.'? Let's see: first 3 rows, first 3 columns: all '.'? The output shows first 3 rows: first 3 columns are '.'? Let's check: first row: ". . . A A A . . ." So first 3 columns are '.'? Yes. Second row: ". . . A A A . . ." So first 3 columns '.'? Yes. Third row: ". . . A A A . . ." So first 3 columns '.'? Yes. So input cell (0,0) '.' maps to 3x3 block of '.'.

Input cell (0,1) is 'A'. In output, the block at rows 0-2, columns 3-5 should be 'A'? Let's check: first row columns 3-5: "A A A". Yes. Second row: "A A A". Third row: "A A A". So yes.

Input cell (0,2) '.' maps to block at rows 0-2, columns 6-8: all '.'? Let's check: first row columns 6-8: ". . .". Yes.

Input cell (1,0) '.' maps to block at rows 3-5, columns 0-2: all '.'? Let's check: row 3 columns 0-2: ". . .". Yes. Row 4: ". . .". Row 5: ". . .". So yes.

Input cell (1,1) 'M' maps to block at rows 3-5, columns 3-5: all 'M'? Let's check: row 3 columns 3-5: "M M M". Row 4: "M M M". Row 5: "M M M". Yes.

Input cell (1,2) 'M' maps to block at rows 3-5, columns 6-8: all 'M'? Let's check: row 3 columns 6-8: "M M M". Row 4: "M M M". Row 5: "M M M". Yes.

Input cell (2,0) 'W' maps to block at rows 6-8, columns 0-2: all 'W'? Let's check: row 6 columns 0-2: "W W W". Row 7: "W W W". Row 8: "W W W". Yes.

Input cell (2,1) 'A' maps to block at rows 6-8, columns 3-5: all 'A'? Let's check: row 6 columns 3-5: "A A A". Row 7: "A A A". Row 8: "A A A". Yes.

Input cell (2,2) '.' maps to block at rows 6-8, columns 6-8: all '.'? Let's check: row 6 columns 6-8: ". . .". Row 7: ". . .". Row 8: ". . .". Yes.

So the transformation is: each cell expands to a block of size N x N, where N is the number of distinct colors (including '.'?) in the input grid? Let's check: Input grid has colors: '.' (black), 'A', 'M', 'W'. That's 4 distinct colors. But the block size is 3, not 4. So maybe N is the number of distinct non-blank colors? Let's count: 'A', 'M', 'W' = 3. That matches block size 3. So the rule: For each cell, expand to a block of size equal to the number of distinct non-blank colors in the input grid. Each block is filled with the same color as the original cell. The spatial arrangement is preserved: each cell's block is placed in the same relative position.

But the description says: "Every room and every vacancy scales up its footprint equally, determined by how many distinct tenants occupy the building — more tenants, grander rooms for all." That matches: number of distinct tenants (colors) determines scaling factor. "Grid details: The blueprint grows proportionally, each original unit becoming a square block, maintaining the spatial relationships of the original design." So yes.

Thus transformation rule: Let k = number of distinct non-blank colors in input grid. For each cell, replace it with a k x k block of the same color. The output grid will be k times larger in each dimension.

Now we need to apply to test input:

Test Input:
```
. B .
. A O
W W .
```

Let's parse: 3 rows, 3 columns.

Row 0: '.' 'B' '.'
Row 1: '.' 'A' 'O'
Row 2: 'W' 'W' '.'

We need to find distinct non-blank colors: 'B', 'A', 'O', 'W'. That's 4 distinct colors. So scaling factor k = 4. So output grid will be 12x12 (3*4 = 12). Each input cell expands to a 4x4 block of the same color.

Let's confirm with example: In example 1, distinct non-blank colors were 'A', 'M', 'W' = 3, scaling factor 3. Yes.

Thus for test input, scaling factor 4.

Now we need to produce the 12x12 output grid. Let's map each input cell to a 4x4 block.

We need to produce output grid with 12 rows, each row with 12 characters separated by spaces.

Let's index input cells:

Input coordinates (row, col):
(0,0) = '.'
(0,1) = 'B'
(0,2) = '.'
(1,0) = '.'
(1,1) = 'A'
(1,2) = 'O'
(2,0) = 'W'
(2,1) = 'W'
(2,2) = '.'

Now we need to produce output grid: For each input cell, produce a 4x4 block of that color. The block's top-left corner in output grid is at (row*4, col*4). So output grid rows 0-3 correspond to input row 0, columns 0-3 correspond to input col

We need to solve a grid transformation puzzle. We have training examples. We need to deduce the transformation rule. Let's analyze.

We have a grid transformation puzzle. Input grid is small (3x3). Output grid is larger (9x9 or 12x12). The transformation seems to involve expanding each cell into a 3x3 block? Let's examine Example 1.

Example 1 Input:
```
. A .
. M M
W A .
```
So 3x3 grid. Output is 9x9 grid. Let's examine output:

```
. . . A A A . . .
. . . A A A . . .
. . . A A A . . .
. . . M M M M M M
. . . M M M M M M
. . . M M M M M M
W W W A A A . . .
W W W A A A . . .
W W W A A A . . .
```

We can see that each input cell is expanded into a 3x3 block. But the mapping of colors is not straightforward: For example, input cell (0,0) is '.' (black). In output, the top-left 3x3 block is all '.'? Let's check: The output top-left 3x3 block is:

Rows 0-2, columns 0-2: all '.'? Let's check: Row 0: ". . .", Row 1: ". . .", Row 2: ". . .". Yes, all '.'.

Input cell (0,1) is 'A' (azure). In output, the block at rows 0-2, columns 3-5: all 'A'? Let's check: Row 0: "A A A", Row 1: "A A A", Row 2: "A A A". Yes, all 'A'.

Input cell (0,2) is '.' again. Output block rows 0-2, columns 6-8: all '.'? Row 0: ". . .", Row 1: ". . .", Row 2: ". . .". Yes.

Input cell (1,0) is '.' again. Output block rows 3-5, columns 0-2: all '.'? Let's check: Row 3: ". . .", Row 4: ". . .", Row 5: ". . .". Yes.

Input cell (1,1) is 'M' (magenta). Output block rows 3-5, columns 3-5: all 'M'? Let's check: Row 3: "M M M", Row 4: "M M M", Row 5: "M M M". Yes.

Input cell (1,2) is 'M' again. Output block rows 3-5, columns 6-8: all 'M'? Row 3: "M M M", Row 4: "M M M", Row 5: "M M M". Yes.

Input cell (2,0) is 'W' (maroon). Output block rows 6-8, columns 0-2: all 'W'? Row 6: "W W W", Row 7: "W W W", Row 8: "W W W". Yes.

Input cell (2,1) is 'A'. Output block rows 6-8, columns 3-5: all 'A'? Row 6: "A A A", Row 7: "A A A", Row 8: "A A A". Yes.

Input cell (2,2) is '.' again. Output block rows 6-8, columns 6-8: all '.'? Row 6: ". . .", Row 7: ". . .", Row 8: ". . .". Yes.

So Example 1: Each input cell expands to a 3x3 block of the same color. So the transformation is simply scaling by factor 3, replicating each cell into a 3x3 block. But we need to confirm with other examples.

Example 2 Input:
```
B . Y
. Y .
. B .
```
Output:
```
B B . . Y Y
B B . . Y Y
. . Y Y . .
. . Y Y . .
. . B B . .
. . B B . .
```
Let's analyze. Input is 3x3. Output is 6x6. So scaling factor 2? Let's check: Input cell (0,0) is 'B'. Output block rows 0-1, columns 0-1: "B B" in row 0, "B B" in row 1. Yes.

Input cell (0,1) is '.' (black). Output block rows 0-1, columns 2-3: ". ." in row 0, ". ." in row 1. Yes.

Input cell (0,2) is 'Y'. Output block rows 0-1, columns 4-5: "Y Y" in row 0, "Y Y" in row 1. Yes.

Input cell (1,0) is '.' (black). Output block rows 2-3, columns 0-1: ". ." in row 2, ". ." in row 3. Yes.

Input cell (1,1) is 'Y'. Output block rows 2-3, columns 2-3: "Y Y" in row 2, "Y Y" in row 3. Yes.

Input cell (1,2) is '.' (black). Output block rows 2-3, columns 4-5: ". ." in row 2, ". ." in row 3. Yes.

Input cell (2,0) is '.' (black). Output block rows 4-5, columns 0-1: ". ." in row 4, ". ." in row 5. Yes.

Input cell (2,1) is 'B'. Output block rows 4-5, columns 2-3: "B B" in row 4, "B B" in row 5. Yes.

Input cell (2,2) is '.' (black). Output block rows 4-5, columns 4-5: ". ." in row 4, ". ." in row 5. Yes.

So Example 2: scaling factor 2.

Example 3 Input:
```
G R .
. O G
. . .
```
Output:
```
G G G R R R . . .
G G G R R R . . .

Input cell (2,2) '.' -> block rows 6-8, cols 6-8: all '.'. Yes.

So scaling factor 3 again.

We need to solve a grid transformation puzzle. We have training examples. We need to deduce the rule. Let's analyze.

We have a grid transformation puzzle. Input grid is small (3x3). Output grid is larger (9x9). The transformation seems to involve expanding each cell into a 3x3 block? Let's examine Example 1.

Example 1 Input:
```
. A .
. M M
W A .
```
So 3x3 grid. Output is 9x9 grid. Let's write the output grid from example 1:

```
. . . A A A . . .
. . . A A A . . .
. . . A A A . . .
. . . M M M M M M
. . . M M M M M M
. . . M M M M M M
W W W A A A . . .
W W W A A A . . .
W W W A A A . . .
```

Let's analyze mapping. Input cell (0,0) is '.' (black). In output, the top-left 3x3 block is all '.'? Let's check: The first 3 rows, first 3 columns: all '.'? The output shows first 3 rows: first 3 columns are '.'? Let's check: Row 0: ". . . A A A . . ." So first 3 columns are '.' '.' '.' yes. Row 1: same. Row 2: same. So yes, the top-left 3x3 block is all '.'.

Input cell (0,1) is 'A'. In output, the block at rows 0-2, columns 3-5 is 'A'? Let's check: Row 0: columns 3-5: "A A A". Row 1: same. Row 2: same. So yes, 3x3 block of 'A'.

Input cell (0,2) is '.' again. Output block rows 0-2, columns 6-8: all '.'? Row 0: columns 6-8: ". . .". Row 1: same. Row 2: same. So yes.

Input cell (1,0) is '.' again. Output block rows 3-5, columns 0-2: all '.'? Let's check: Row 3: ". . . M M M M M M" Wait row 3: first 3 columns are '.' '.' '.'? Actually row 3: ". . . M M M M M M". So yes, first 3 columns '.' '.' '.'.

Input cell (1,1) is 'M'. Output block rows 3-5, columns 3-5: 'M'? Let's check: Row 3: columns 3-5: "M M M". Row 4: same. Row 5: same. So yes.

Input cell (1,2) is 'M'. Output block rows 3-5, columns 6-8: 'M'? Row 3: columns 6-8: "M M M". Row 4: same. Row 5: same. So yes.

Input cell (2,0) is 'W'. Output block rows 6-8, columns 0-2: 'W'? Row 6: "W W W A A A . . .". So first 3 columns are 'W W W'. Row 7: same. Row 8: same. So yes.

Input cell (2,1) is 'A'. Output block rows 6-8, columns 3-5: 'A'? Row 6: columns 3-5: "A A A". Row 7: same. Row 8: same. So yes.

Input cell (2,2) is '.' again. Output block rows 6-8, columns 6-8: '.'? Row 6: columns 6-8: ". . .". Row 7: same. Row 8: same. So yes.

Thus the transformation is: each input cell expands into a 3x3 block of the same color. So the output grid is 3 times larger in each dimension (3x3 input -> 9x9 output). Each cell is replaced by a 3x3 block of that cell's color.

But we need to confirm with Example 2 and 3.

Example 2 Input:
```
B . Y
. Y .
. B .
```
Output:
```
B B . . Y Y
B B . . Y Y
. . Y Y . .
. . Y Y . .
. . B B . .
. . B B . .
```
Let's analyze: Input 3x3 -> output 6x6? Wait output is 6x6. Let's check: The output grid has 6 rows, each row has 6 columns. So scaling factor is 2? Let's check mapping: Input cell (0,0) is 'B'. Output block rows 0-1, columns 0-1: 'B'? Row 0: "B B . . Y Y". So columns 0-1: "B B". Row 1: same. So yes.

Input cell (0,1) is '.' -> output block rows 0-1, columns 2-3: '.'? Row 0: columns 2-3: ". .". Row 1: same. So yes.

Input cell (0,2) is 'Y' -> output block rows 0-1, columns 4-5: 'Y'? Row 0: columns 4-5: "Y Y". Row 1: same. So yes.

Input cell (1,0) is '.' -> output block rows 2-3, columns 0-1: '.'? Row 2: ". . Y Y . .". So columns 0-1: ". .". Row 3: same. So yes.

Input cell (1,1) is 'Y' -> output block rows 2-3, columns 2-3: 'Y'? Row 2: columns 2-3: "Y Y". Row 3: same. So yes.

Input cell (1,2) is '.' -> output block rows 2-3, columns 4-5: '.'? Row 2: columns 4-5: ". .". Row 3: same. So yes.

Input cell (2,0) is '.' -> output block rows 4-5, columns 0-1: '.'? Row 4: ". . B B . .". So columns 0-1: ". .". Row 5: same. So yes.

Input cell (2,1) is 'B' -> output block rows 4-5, columns 2-3: 'B'? Row 4: columns 2-3: "B B". Row 5: same. So yes.

Input cell (2,2) is '.' -> output block rows 4-5, columns 4-5: '.'? Row 4: columns 4-5: ". .". Row 5: same. So yes.

Thus scaling factor 2. So the scaling factor is not constant across examples. Example 1 scaling factor 3, Example 2 scaling factor 2, Example 3 scaling factor 3? Let's check Example 3.

Example 3 Input:
```
G R .
. O G
. . .
```
Output:
```
G G G R R R . . .
G G G R R R . . .
G G G R R R . . .
. . . O O O G G G
. . . O O O G G G
. . . O O O G G G
. . . . . . . . .

This is 9x9 output. So scaling factor 3 again. So scaling factor depends on something. Let's analyze the input grid: Example 1 had 3x3 input, output 9x9 scaling factor 3. Example 2 had 3x3 input, output 6x6 scaling factor 2. Example 3 had 3x3 input, output 9x9 scaling factor 3. So scaling factor is not constant across all examples. So there must be some rule that determines scaling factor based on something else, maybe the number of distinct colors? The description says: "Each spotlight and each shadow expands into a square region whose dimensions equal the number of distinct characters performing." Let's parse the metaphor: "What you see: A small stage 

... [7342 chars truncated]

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A small plot with colored plantings and bare soil arranged in a grid. What to do: Each plant and each bare patch claims a square territory whose side equals the number of distinct species in the garden. Grid details: The garden expands uniformly from its original layout, every plot position becoming a larger square block."

We have training example 1: Input grid 3x3? Let's parse.

Example 1 Input:
```
. A .
. M M
W A .
```
So 3 rows, 3 columns. Colors: '.' black, 'A' azure, 'M' magenta, 'W' maroon.

Output grid:
```
. . . A A A . . .
. . . A A A . . .
. . . A A A . . .
. . . M M M M M M
. . . M M M M M M
. . . M M M M M M
W W W A A A . . .
W W W A A A . . .
W W W A A A . . .
```
So output grid is 9x9? Let's count: each row has 9 characters. Yes 9x9. So the transformation expands each cell into a 3x3 block? Wait 3x3 input -> 9x9 output. So each cell becomes a 3x3 block. But the pattern is not uniform: For example, input cell (0,0) is '.' (black). In output, the top-left 3x3 block is all '.'? Let's check: Output rows 0-2, columns 0-2: all '.'? The output shows first 3 rows: ". . . A A A . . ." So first 3 columns are '.'? Actually row 0: ". . . A A A . . ." So columns 0-2 are '.'; columns 3-5 are 'A'; columns 6-8 are '.'.

So the first 3x3 block (rows 0-2, cols 0-2) is all '.'? Yes. That matches input cell (0,0) '.'.

Input cell (0,1) is 'A'. In output, the block rows 0-2, cols 3-5 is 'A' repeated. So that block is all 'A'. Good.

Input cell (0,2) is '.' again. Output block rows 0-2, cols 6-8 is '.'.

Input cell (1,0) is '.'? Wait row 1 of input: ". M M". So cell (1,0) '.'; block rows 3-5, cols 0-2 is '.'? Let's check output rows 3-5: ". . . M M M M M M" Wait row 3: ". . . M M M M M M". So columns 0-2 are '.'? Yes. So block rows 3-5, cols 0-2 is '.'.

Input cell (1,1) is 'M'. Output block rows 3-5, cols 3-5 is 'M'? Let's check row 3: ". . . M M M M M M". So columns 3-5 are 'M'. Good.

Input cell (1,2) is 'M'. Output block rows 3-5, cols 6-8 is 'M'? Row 3: columns 6-8 are 'M'. Yes.

Input cell (2,0) is 'W'. Output block rows 6-8, cols 0-2 is 'W'? Row 6: "W W W A A A . . .". So columns 0-2 are 'W'. Good.

Input cell (2,1) is 'A'. Output block rows 6-8, cols 3-5 is 'A'? Row 6: columns 3-5 are 'A'. Yes.

Input cell (2,2) is '.'? Wait row 2 of input: "W A .". So cell (2,2) '.'; output block rows 6-8, cols 6-8 is '.'? Row 6: columns 6-8 are '.'.

So transformation is: each input cell expands to a block of size equal to number of distinct species in the garden? Wait the description: "Each plant and each bare patch claims a square territory whose side equals the number of distinct species in the garden." So the side length of each block equals the number of distinct species in the garden. In example 1, distinct species: '.' (black), 'A', 'M', 'W' => 4 distinct? Wait '.' counts as a species? The description says "Each plant and each bare patch claims a square territory whose side equals the number of distinct species in the garden." So maybe '.' counts as a species? But the side length of each block is 3? Wait we saw each block is 3x3. So side length 3. So number of distinct species must be 3. Let's count distinct colors in input: '.' (black), 'A', 'M', 'W' => 4. But maybe '.' is not counted? But the description says "bare patch" is '.'; maybe it's considered a species? But the side length is 3, not 4. So maybe '.' is not counted. Let's check: distinct non-'.' colors: 'A', 'M', 'W' => 3. So side length 3. That matches. So the rule: side length = number of distinct non-'.' colors in the input grid. Each cell expands to a block of that side length, filled with the same color as the cell. So basically a scaling transformation: each cell becomes a block of size N x N, where N = number of distinct non-'.' colors in the input grid. The output grid is N times larger in each dimension: input size 3x3 -> output 9x9 (3*3). That matches.

But we need to confirm with the test input: 
Test Input:
```
. B .
. A O
W W .
```
We need to compute number of distinct non-'.' colors: 'B', 'A', 'O', 'W' => 4 distinct. So N=4. So each input cell expands to a 4x4 block. Input grid is 3x3, so output grid will be 12x12. Let's confirm with the description: "Each plant and each bare patch claims a square territory whose side equals the number of distinct species in the garden." So side length = number of distinct species. Distinct species includes all colors? But we need to decide if '.' counts. In example 1, we had 4 distinct colors including '.' but side length 3. So '.' not counted. So we count only non-'.' colors. So N=4.

Thus output grid will be 12x12. Each input cell expands to a 4x4 block of its color. So we need to produce a 12x12 grid.

But we need to double-check if there are any other transformations: maybe the output grid is not just scaling but also some arrangement? Let's examine the output grid of example 1: It is exa

We need to parse the puzzle. The description: "grid transformation puzzle" with metaphorical description. We have training examples. We need to deduce rule. Let's analyze.

We have a 3-lane grid: top, middle, bottom rows. The center lane is always full of yellow marchers. The outer lanes alternate presence and absence in opposite lockstep. So top lane has pattern Y . Y . Y ...? bottom lane has . Y . Y . Y ...? They are offset by one cell. The grid length can vary.

The transformation: "drumbeat sounds every three steps along the center lane, and each marcher standing on that beat swaps their yellow uniform for a magenta one." So at positions in center lane that are multiples of 3 steps? Starting from first cell? "every three steps along the center lane" likely means positions 0,3,6,9,...? But we need to confirm with examples.

Also "outer lanes hear a slower rhythm — a cymbal crash every six steps. But the two outer lanes are offset from each other: whichever lane has a marcher standing at the start of the route hears the crash on the downbeat, while the lane that begins with a gap hears it on the off-beat, halfway between crashes. Wherever a crash lands on an occupied position, that marcher also turns magenta. Empty gaps stay empty — you can't dye what isn't there."

So for outer lanes: there is a crash every 6 steps. But the lanes are offset: the lane that starts with a marcher at the start of the route hears the crash on the downbeat (i.e., at positions 0,6,12,...). The lane that starts with a gap hears it on the off-beat, halfway between crashes (i.e., at positions 3,9,15,...). So basically for outer lanes, the positions that get magenta are those that are multiples of 6 for the lane that starts with a marcher, and those that are multiples of 6 plus 3 for the lane that starts with a gap.

But we need to confirm with training examples.

Let's analyze Example 1.

Input grid:

Row1: Y . Y . Y . Y . Y . Y . Y
Row2: Y Y Y Y Y Y Y Y Y Y Y Y Y
Row3: . Y . Y . Y . Y . Y . Y .

Let's write indices 0-based across columns.

Row1: positions: 0:Y,1:.,2:Y,3:.,4:Y,5:.,6:Y,7:.,8:Y,9:.,10:Y,11:.,12:Y
Row2: all Y across 13 columns.
Row3: 0:.,1:Y,2:.,3:Y,4:.,5:Y,6:.,7:Y,8:.,9:Y,10:.,11:Y,12:.

So top lane starts with Y at position 0. Bottom lane starts with . at position 0. So top lane offset 0, bottom lane offset 1 relative to Y pattern.

Now output grid:

Row1: M . Y . Y . M . Y . Y . M
Row2: M Y Y M Y Y M Y Y M Y Y M
Row3: . Y . M . Y . Y . M . Y .

Let's analyze each row.

Row1: positions: 0:M,1:.,2:Y,3:.,4:Y,5:.,6:M,7:.,8:Y,9:.,10:Y,11:.,12:M

So Y at positions 0,2,4,6,8,10,12 originally. After transformation, Y at 0 changed to M, 2 remains Y, 4 remains Y, 6 changed to M, 8 remains Y, 10 remains Y, 12 changed to M. So positions 0,6,12 changed to M. These are multiples of 6? 0,6,12 yes. So for top lane, positions multiples of 6 changed to M. That matches the rule: top lane starts with Y at position 0, so it hears crash on downbeat at positions 0,6,12,... So those positions become M.

Row3: positions: 0:.,1:Y,2:.,3:M,4:.,5:Y,6:.,7:Y,8:.,9:M,10:.,11:Y,12:.

Original Y at positions 1,3,5,7,9,11. After transformation, Y at 1 remains Y, 3 changed to M, 5 remains Y, 7 remains Y, 9 changed to M, 11 remains Y. So positions 3,9 changed to M. These are positions 3,9 which are multiples of 6 plus 3. So bottom lane offset 1, so it hears crash at positions 3,9,15,... So that matches.

Now center lane: Row2: original Y at all positions 0-12. Output: M Y Y M Y Y M Y Y M Y Y M. So Y at positions 0 changed to M, 1 remains Y, 2 remains Y, 3 changed to M, 4 remains Y, 5 remains Y, 6 changed to M, 7 remains Y, 8 remains Y, 9 changed to M, 10 remains Y, 11 remains Y, 12 changed to M. So positions 0,3,6,9,12 changed to M. These are multiples of 3. So center lane: every 3 steps (positions 0,3,6,9,12) changed to M. That matches rule: drumbeat every 3 steps along center lane.

Thus rule confirmed.

Now we need to apply to test input.

Test Input:

Row1: . Y . Y . Y . Y . Y . Y . Y . Y .
Row2: Y Y Y Y Y Y Y Y Y Y Y Y Y Y Y Y Y
Row3: Y . Y . Y . Y . Y . Y . Y . Y . Y

Let's parse.

Row1: pattern: . Y . Y . Y . Y . Y . Y . Y . Y . (positions 0-? Let's count). There are 17 columns? Let's count: The string: ". Y . Y . Y . Y . Y . Y . Y . Y ." That's 17 tokens: positions 0 to 16. Let's confirm: tokens: 0:.,1:Y,2:.,3:Y,4:.,5:Y,6:.,7:Y,8:.,9:Y,10:.,11:Y,12:.,13:Y,14:.,15:Y,16:. So top lane starts with . at position 0. So top lane offset 1 relative to Y pattern. So top lane is like bottom lane in example 1: offset 1.

Row2: all Y across 17 columns.

Row3: pattern: Y . Y . Y . Y . Y . Y . Y . Y . Y (positions 0-16). So bottom lane starts with Y at position 0. So bottom lane offset 0.

Thus top lane offset 1, bottom lane offset 0.

Now we need to apply transformation.

We need to produce output grid of same size: 3 rows, 17 columns.

We need to convert Y to M at positions:

- Center lane: positions multiples of 3: 0,3,6,9,12,15? Wait 15 is m

We need to solve a grid transformation puzzle. We have training examples. We need to deduce the rule. Let's parse the problem carefully.

We have a metaphorical description: "Three horizontal bands of golden stars: a continuous central band and two outer bands with alternating stars and voids in opposite phase. What to do: Magenta flares erupt periodically in the central band. The outer bands flare at double the interval, only on stars positioned at the resonant points. Grid details: Three rows. Center row solid golden. Outer rows alternate golden/dark oppositely. Magenta replaces golden at regular intervals — twice as dense in the center."

We have color key: .=black B=blue R=red G=green Y=yellow X=grey M=magenta O=orange A=azure W=maroon

So Y=yellow is golden stars. '.' is black (void). M=magenta is the flare. The puzzle: we have 3 rows. The center row is all Y. Outer rows alternate Y and . in opposite phase. So row1: Y . Y . Y . ... row3: . Y . Y . Y ... etc. The transformation: Magenta flares erupt periodically in the central band. The outer bands flare at double the interval, only on stars positioned at the resonant points.

So we need to map input to output. Let's examine training examples.

Example 1:

Input:
Row1: Y . Y . Y . Y . Y . Y . Y
Row2: Y Y Y Y Y Y Y Y Y Y Y Y Y
Row3: . Y . Y . Y . Y . Y . Y .

Output:
Row1: M . Y . Y . M . Y . Y . M
Row2: M Y Y M Y Y M Y Y M Y Y M
Row3: . Y . M . Y . Y . M . Y .

Let's analyze.

Input row1: Y . Y . Y . Y . Y . Y . Y (length 13). Output row1: M . Y . Y . M . Y . Y . M. So positions: 1,7,13 changed to M. Others remain Y or . unchanged. So pattern: every 6th? Let's index positions 1-13. Input row1: Y at odd positions 1,3,5,7,9,11,13. Output row1: M at positions 1,7,13. So M at positions 1,7,13. That's positions 1, 7, 13. That's 6 apart. So M at positions 1, 7, 13. So pattern: M at positions 1 + 6k. So M at positions 1,7,13. So basically every 6th Y becomes M. So the interval is 6. So the rule: In outer rows, Y's become M at positions that are multiples of 6? But we need to check row3.

Row3 input: . Y . Y . Y . Y . Y . Y . (positions 1-13). Output row3: . Y . M . Y . Y . M . Y . So M at positions 4 and 10? Wait let's index: positions: 1 '.'; 2 'Y'; 3 '.'; 4 'Y'; 5 '.'; 6 'Y'; 7 '.'; 8 'Y'; 9 '.'; 10 'Y'; 11 '.'; 12 'Y'; 13 '.'. Output: . Y . M . Y . Y . M . Y . So M at positions 4 and 10. So positions 4 and 10. That's also 6 apart. So M at positions 4,10. So pattern: In outer rows, Y's become M at positions 4,10, etc. So offset 4 relative to row1's offset 1. So row1 offset 1, row3 offset 4. So pattern: Outer rows alternate offset by 3? Wait difference between 1 and 4 is 3. But row1 offset 1, row3 offset 4. So maybe the offset is 1 for row1, 4 for row3. That matches the description: outer rows alternate golden/dark oppositely. So row1 has Y at odd positions, row3 has Y at even positions. So the M positions are at positions 1,7,13 for row1; 4,10 for row3. So basically M at positions that are 1 mod 6 for row1, 4 mod 6 for row3. So the rule: In outer rows, Y's become M at positions that are 1 mod 6 for row1, 4 mod 6 for row3. That is, every 6th Y starting at the first Y in each row. So the interval is 6. So the outer rows have M at every 6th Y.

Now row2: Input row2: Y Y Y Y Y Y Y Y Y Y Y Y Y (13 Y's). Output row2: M Y Y M Y Y M Y Y M Y Y M. So M at positions 1,4,7,10,13. So M at positions 1,4,7,10,13. That's also every 3? Wait difference 3. So M at positions 1,4,7,10,13. So interval 3. So center row has M at every 3rd Y. So center row is denser: M at every 3rd Y. Outer rows have M at every 6th Y. So that matches the description: "Magenta flares erupt periodically in the central band. The outer bands flare at double the interval, only on stars positioned at the resonant points." So central band has flares at interval 3, outer bands at interval 6. So the rule: In center row, replace Y with M at positions that are 1 mod 3? Wait positions 1,4,7,10,13. That's 1 mod 3? Let's check: 1 mod 3 = 1; 4 mod 3 = 1; 7 mod 3 = 1; 10 mod 3 = 1; 13 mod 3 = 1. Yes. So M at positions 1 mod 3. So center row: M at positions 1 mod 3. Outer rows: M at positions 1 mod 6 for row1, 4 mod 6 for row3. So basically M at positions that are 1 mod 3 in center, 1 mod 6 in outer row1, 4 mod 6 in outer row3. So the rule: In each row, Y's become M at positions that are 1 mod N, where N=3 for center, N=6 for outer rows. But the offset for outer rows depends on the row: row1 offset 1, row3 offset 4. So we need to figure offset pattern: For row1, offset 1; row3 offset 4. That is 1 mod 6 and 4 mod 6. So basically the offset is 1 for row1, 4 for row3. That is 1 and 4. So maybe offset is 1 for row1, 4 for row3. That is 1 and 4. So maybe the offset is 1 for the first outer row, 4 for the second outer row. So the rule: For outer rows, M at positions that are 1 mod 6 for the top outer row, 4 mod 6 for the bottom outer row. That matches the pattern.

Now let's check Example 2.

Example 2 Input:
Row1:

We need to solve a grid transformation puzzle. We have training examples. We need to deduce the rule. Let's parse the problem carefully.

We have a metaphorical description: "What you see: Three horizontal lines of golden buoys: a solid center channel marker flanked by two alternating lines with buoys and gaps in opposite arrangement. What to do: A periodic lighthouse beam turns some golden buoys magenta. The center line is swept most often; flanking lines are caught at half the frequency, only where buoys sit at the right positions. Grid details: Three rows. Center row all golden. Outer rows alternate golden/empty in antiphase. Magenta replaces golden at regular spacings."

We have color key: .=black B=blue R=red G=green Y=yellow X=grey M=magenta O=orange A=azure W=maroon

So the grid uses '.' for black, Y for yellow, M for magenta. The input grid uses Y and '.' only. The output grid uses Y, M, and '.'.

We need to deduce transformation rule: For each cell, maybe some cells become M (magenta) based on some pattern.

Let's analyze training examples.

Example 1:

Input:
Row1: Y . Y . Y . Y . Y . Y . Y
Row2: Y Y Y Y Y Y Y Y Y Y Y Y Y
Row3: . Y . Y . Y . Y . Y . Y .

Output:
Row1: M . Y . Y . M . Y . Y . M
Row2: M Y Y M Y Y M Y Y M Y Y M
Row3: . Y . M . Y . Y . M . Y .

Let's write them as arrays.

Input1 Row1: Y . Y . Y . Y . Y . Y . Y
Indices: 0 1 2 3 4 5 6 7 8 9 10 11 12
Input1 Row2: Y Y Y Y Y Y Y Y Y Y Y Y Y
Indices: 0-12
Input1 Row3: . Y . Y . Y . Y . Y . Y .

Output1 Row1: M . Y . Y . M . Y . Y . M
Output1 Row2: M Y Y M Y Y M Y Y M Y Y M
Output1 Row3: . Y . M . Y . Y . M . Y .

Let's analyze pattern.

Observations: In output, some Y cells become M. Which ones? Let's mark positions.

Row1: Input Y at positions 0,2,4,6,8,10,12. Output M at positions 0,6,12. So Y at 0,6,12 become M. Y at 2,4,8,10 remain Y.

Row2: Input Y at all positions 0-12. Output M at positions 0,3,6,9,12. So Y at 0,3,6,9,12 become M. Y at 1,2,4,5,7,8,10,11 remain Y.

Row3: Input Y at positions 1,3,5,7,9,11. Output M at positions 3,9. So Y at 3,9 become M. Y at 1,5,7,11 remain Y.

So pattern: M appears at positions that are multiples of 3? Let's check: positions 0,3,6,9,12 are multiples of 3. Yes. In Row1, Y at positions 0,6,12 are multiples of 3. In Row3, Y at positions 3,9 are multiples of 3. So rule: For each row, Y cells at positions that are multiples of 3 become M. But Row1 has Y at positions 0,2,4,6,8,10,12. Among them, multiples of 3: 0,6,12. Row3 Y at 1,3,5,7,9,11. Multiples of 3: 3,9. So yes.

But we need to confirm with Example 2.

Example 2 Input:
Row1: . Y . Y . Y . Y . Y .
Indices: 0-10? Let's count: . Y . Y . Y . Y . Y . => 11 cells? Actually pattern: . Y . Y . Y . Y . Y . => 11 cells. Let's index 0-10.

Row2: Y Y Y Y Y Y Y Y Y Y Y => 11 cells.

Row3: Y . Y . Y . Y . Y . Y => 11 cells.

Output:
Row1: . Y . M . Y . Y . M .
Row2: M Y Y M Y Y M Y Y M Y
Row3: M . Y . Y . M . Y . Y

Let's analyze.

Row1 Input Y at positions 1,3,5,7,9. Output M at positions 3,9. So Y at 3,9 become M. Y at 1,5,7 remain Y. So again multiples of 3? Let's check: positions 3 and 9 are multiples of 3. Yes.

Row2 Input Y at positions 0-10. Output M at positions 0,3,6,9. So Y at 0,3,6,9 become M. Multiples of 3 again.

Row3 Input Y at positions 0,2,4,6,8,10. Output M at positions 0,6,10? Wait output row3: M . Y . Y . M . Y . Y. Let's index: 0 M, 1 ., 2 Y, 3 ., 4 Y, 5 ., 6 M, 7 ., 8 Y, 9 ., 10 Y. So M at positions 0,6. Wait 10? Actually output row3 has Y at 10. So M at 0,6. But 10 is not multiple of 3. So maybe rule is: Y at positions that are multiples of 3 become M, but also maybe Y at position 0? But 0 is multiple of 3. So yes. So row3 M at 0,6. 0 and 6 are multiples of 3. So rule holds.

Thus rule: For each row, Y cells at positions that are multiples of 3 become M. But we need to confirm that positions start at 0. Yes.

But we also need to consider that the input grid may have '.' cells at positions that are multiples of 3. In that case, output remains '.'? Let's check Example 1 Row1: Input '.' at positions 1,3,5,7,9,11. Output '.' at same positions. So no change.

Thus transformation: For each cell that is Y in input, if its column index modulo 3 equals 0, then output M; else Y. '.' remains '.'.

But we need to confirm that the rule is exactly that. Let's test with Example 1 Row3: Input '.' at positions 0,2,4,6,8,10,12. Output '.' at same positions. So yes.

Thus rule: Replace Y with M at columns that are multiples of 3 (0-indexed). Equivalent to: For each column index i, if i mod 3 == 0, then all Y cells in that column become M. But we need to check if there is any difference between rows. In Example 1 Row1, Y at 0,6,12 become M. Row2 Y at 0,3,6,9,12 become M. Row3 Y at 3,9 become M. So yes, all Y cells at columns 0,3,6,9,12 become M. So rule: For each column index that is multiple of 3, all Y cells in that column become M. But we need to confirm that there is no difference between rows. In Example 1 Row3, Y at 3,9 become M. Yes. So r

We need to solve a grid transformation puzzle. We have a metaphorical description: "Three golden threads on a cosmic loom: a solid center thread and two flanking threads that alternate woven/unwoven in opposite pattern. Magenta ichor marks the threads at regular intervals. The center thread is marked most densely; the outer threads receive marks at half the rate, only where thread is present at the right interval."

We have training examples. Let's parse them.

Example 1:

Input:
```
Y . Y . Y . Y . Y . Y . Y
Y Y Y Y Y Y Y Y Y Y Y Y Y
. Y . Y . Y . Y . Y . Y .
```
Output:
```
M . Y . Y . M . Y . Y . M
M Y Y M Y Y M Y Y M Y Y M
. Y . M . Y . Y . M . Y .
```

We need to understand the transformation rule.

We have a 3-row grid. Input uses Y and . (yellow and black). Output uses M (magenta) and Y and . . So transformation: some Y cells become M. The pattern: In the input, the middle row is all Y. The top and bottom rows alternate Y and . starting with Y at first column. So top row: Y . Y . Y . Y . Y . Y . Y (13 columns). Bottom row: . Y . Y . Y . Y . Y . Y . (13 columns). So top row has Y at even columns (0-indexed?), bottom row has Y at odd columns.

Output: Let's examine each row.

Row 0 output: M . Y . Y . M . Y . Y . M
Row 1 output: M Y Y M Y Y M Y Y M Y Y M
Row 2 output: . Y . M . Y . Y . M . Y .

We need to see pattern: In output, some Y cells changed to M. Which ones? Let's compare row by row.

Row 0 input: Y . Y . Y . Y . Y . Y . Y
Output: M . Y . Y . M . Y . Y . M

Positions: 0: Y -> M. 1: . stays . 2: Y stays Y 3: . stays . 4: Y stays Y 5: . stays . 6: Y -> M 7: . stays . 8: Y stays Y 9: . stays . 10: Y stays Y 11: . stays . 12: Y -> M

So in row 0, Y at positions 0,6,12 changed to M. That's every 6 columns? Let's check: positions 0,6,12 difference 6. So pattern: every 6 columns starting at 0. So maybe the rule: In the center row, all Y become M? Wait row 1 output: M Y Y M Y Y M Y Y M Y Y M. Input row 1: Y Y Y Y Y Y Y Y Y Y Y Y Y. Output: M Y Y M Y Y M Y Y M Y Y M. So positions 0,3,6,9,12 changed to M. That's every 3 columns starting at 0. So center row: every 3rd cell becomes M. Row 2 output: . Y . M . Y . Y . M . Y . . Wait row 2 input: . Y . Y . Y . Y . Y . Y . . Wait input row 2: . Y . Y . Y . Y . Y . Y . (13 columns). Output: . Y . M . Y . Y . M . Y . . Wait output row 2: . Y . M . Y . Y . M . Y . . Wait there are 13 columns? Let's count: . Y . M . Y . Y . M . Y . . That's 14? Let's check carefully. The output row 2 in example: ". Y . M . Y . Y . M . Y ." Actually the example shows: ". Y . M . Y . Y . M . Y ." That's 13 columns: positions 0: .; 1: Y; 2: .; 3: M; 4: .; 5: Y; 6: .; 7: Y; 8: .; 9: M; 10: .; 11: Y; 12: . . Wait there is an extra dot at the end? Let's count: 0 ., 1 Y, 2 ., 3 M, 4 ., 5 Y, 6 ., 7 Y, 8 ., 9 M, 10 ., 11 Y, 12 . That's 13 columns. Good.

So row 2: Y at positions 1,5,7,11 changed to M at positions 3,9? Wait Y at positions 1,5,7,11. Output: Y at 1 remains Y; Y at 5 remains Y; Y at 7 remains Y; Y at 11 remains Y. But M appears at positions 3 and 9. Those positions originally had . in input. So M appears at positions 3 and 9. So M appears at positions that were originally .? Wait row 2 input had . at positions 0,2,4,6,8,10,12. Output has M at positions 3 and 9, which were originally .? Wait 3 and 9 are originally .? Let's check: Input row 2: . Y . Y . Y . Y . Y . Y . So positions: 0 ., 1 Y, 2 ., 3 Y, 4 ., 5 Y, 6 ., 7 Y, 8 ., 9 Y, 10 ., 11 Y, 12 . . Wait I mis-copied earlier. Let's re-evaluate: Input row 2: . Y . Y . Y . Y . Y . Y . (13 columns). So Y at positions 1,3,5,7,9,11. . at positions 0,2,4,6,8,10,12. Output row 2: . Y . M . Y . Y . M . Y . . Wait output row 2: . Y . M . Y . Y . M . Y . . Wait there is an extra dot at the end? Let's parse: The output row 2 string: ". Y . M . Y . Y . M . Y ." That's 13 columns: 0 ., 1 Y, 2 ., 3 M, 4 ., 5 Y, 6 ., 7 Y, 8 ., 9 M, 10 ., 11 Y, 12 . . So M at positions 3 and 9. Those positions originally had Y in input. So M replaced Y at positions 3 and 9. So M appears at Y positions at positions 3 and 9. So pattern: In row 2, Y at positions 3 and 9 changed to M. That's every 6 columns starting at 3? Let's check: positions 3,9 difference 6. So yes, every 6 columns starting at 3. So row 2: Y at positions 3,9 changed to M. Row 0: Y at positions 0,6,12 changed to M. Row 1: Y at positions 0,3,6,9,12 changed to M. So pattern: In each row, Y cells at positions that are multiples of 3? Wait row 1: positions 0,3,6,9,12 are multiples of 3. Row 0: positions 0,6,12 are multiples of 6? Actually 0,6,12 are multiples of 6. Row 2: positions 3,9 are multiples of 6 plus 3. So pattern: In row 0, Y at positions that are multiples of 6. In row 1, Y at positions that are multiples of 3. In row 2, Y at positions that are multiples of 6 plus 3. So basically, the pattern of M marks is a periodic pattern across the grid: maybe a 3x? pattern.

Let's examine the grid as a 3x13 grid. Let's index columns 0-12. Let's mark Y positions in input:

Row 0: Y at 0,2,4

We need to solve a grid transformation puzzle. We have training examples. Let's parse them carefully.

We have a grid transformation puzzle. The input grid is 3 rows. The output grid is also 3 rows. The grid uses characters: '.' for black, Y for yellow, M for magenta, etc. The transformation seems to replace some Y's with M's according to some rule. Let's analyze the training examples.

Example 1:

Input:
Row1: Y . Y . Y . Y . Y . Y . Y
Row2: Y Y Y Y Y Y Y Y Y Y Y Y Y
Row3: . Y . Y . Y . Y . Y . Y .

Output:
Row1: M . Y . Y . M . Y . Y . M
Row2: M Y Y M Y Y M Y Y M Y Y M
Row3: . Y . M . Y . Y . M . Y .

Let's write them in a grid with coordinates. Let's index columns from 0 to maybe 12? Let's count: Row1 has 13 entries: Y . Y . Y . Y . Y . Y . Y. That's 13 columns. Row2 has 13 Y's. Row3 has 13 entries: . Y . Y . Y . Y . Y . Y . That's 13 columns. So grid is 3x13.

Output Row1: M . Y . Y . M . Y . Y . M. That's 13 entries. Row2: M Y Y M Y Y M Y Y M Y Y M. Row3: . Y . M . Y . Y . M . Y . That's 13 entries.

So transformation: Some Y's replaced by M's. Let's mark positions.

Let's index columns 0-12.

Input Row1: col0 Y, col1 ., col2 Y, col3 ., col4 Y, col5 ., col6 Y, col7 ., col8 Y, col9 ., col10 Y, col11 ., col12 Y.

Output Row1: col0 M, col1 ., col2 Y, col3 ., col4 Y, col5 ., col6 M, col7 ., col8 Y, col9 ., col10 Y, col11 ., col12 M.

So Y at col0 replaced by M. Y at col2 remains Y. Y at col4 remains Y. Y at col6 replaced by M. Y at col8 remains Y. Y at col10 remains Y. Y at col12 replaced by M.

So pattern: Y at even columns 0,2,4,6,8,10,12. In output, Y at columns 0,6,12 replaced by M. Y at columns 2,4,8,10 remain Y. So maybe every third Y? Let's check: positions 0,6,12 are multiples of 6? 0,6,12. Yes. So maybe replace Y at columns that are multiples of 6? But 6 is 6, 12 is 12. 0 is 0. So yes, multiples of 6. But we need to check other rows.

Row2 Input: all Y's. Output Row2: M Y Y M Y Y M Y Y M Y Y M. So positions 0,3,6,9,12 replaced by M. So Y at columns 0,3,6,9,12 replaced by M. So pattern: every third column? 0,3,6,9,12. Yes. So for row2, replace Y at columns that are multiples of 3? Actually 0,3,6,9,12 are multiples of 3. So yes.

Row3 Input: . Y . Y . Y . Y . Y . Y . (positions 1,3,5,7,9,11). Output Row3: . Y . M . Y . Y . M . Y . So Y at columns 3 and 9 replaced by M. So Y at columns 3 and 9 replaced. So pattern: Y at columns 3 and 9 replaced. Those are multiples of 3? 3,6,9,12. But 6 is not present because there is no Y at 6. So Y at columns 3 and 9 replaced. So again multiples of 3. So for row3, Y at columns 3 and 9 replaced. So pattern: Y at columns that are multiples of 3? But row1 had Y at columns 0,2,4,6,8,10,12. Among those, multiples of 3 are 0,6,12. So yes, row1 replaced Y at columns 0,6,12. So rule: For each row, replace Y at columns that are multiples of 3? But row1 had Y at columns 0,2,4,6,8,10,12. Among those, multiples of 3: 0,6,12. So replaced. Row2 had Y at all columns 0-12. Multiples of 3: 0,3,6,9,12 replaced. Row3 had Y at columns 1,3,5,7,9,11. Multiples of 3: 3,6,9,12. But Y at 6 and 12 not present. So replaced Y at 3 and 9. So yes, rule: Replace Y with M at columns that are multiples of 3. But row1 had Y at 0,2,4,6,8,10,12. So Y at 0,6,12 replaced. That matches. So rule: For each row, replace Y with M at columns that are multiples of 3. But we need to check if there are any other changes. Are there any other changes? Let's check if any '.' changed to something else. In all rows, '.' remained '.'.

So rule: For each row, replace Y with M at columns that are multiples of 3. That seems to hold for Example 1.

Now Example 2:

Input:
Row1: . Y . Y . Y . Y . Y .
Row2: Y Y Y Y Y Y Y Y Y Y Y
Row3: Y . Y . Y . Y . Y . Y

Wait, let's parse. Example 2 Input:

Row1: . Y . Y . Y . Y . Y .
Row2: Y Y Y Y Y Y Y Y Y Y Y
Row3: Y . Y . Y . Y . Y . Y

But the given input lines:

Example 2:
Input:
. Y . Y . Y . Y . Y .
Y Y Y Y Y Y Y Y Y Y Y
Y . Y . Y . Y . Y . Y

Yes.

Output:
Row1: . Y . M . Y . Y . M .
Row2: M Y Y M Y Y M Y Y M Y
Row3: M . Y . Y . M . Y . Y

Let's analyze.

Input Row1: . Y . Y . Y . Y . Y . (positions 1,3,5,7,9). Output Row1: . Y . M . Y . Y . M . (positions 1,3,5,7,9). Y at positions 3 and 9 replaced by M. So Y at columns 3 and 9 replaced. Those are multiples of 3? 3,6,9,12. Yes. So Y at 3 and 9 replaced. So rule holds: replace Y at columns multiples of 3.

Input Row2: Y Y Y Y Y Y Y Y Y Y Y (positions 0-10). Output Row2: M Y Y M Y Y M Y Y M Y. So Y at columns 0,3,6,9 replaced by M. Those are multiples of 3. Yes.

Input Row3: Y . Y . Y . Y . Y . Y (positions 0,2,4,6,8,10). Output Row3: M . Y . Y . M . Y . Y. So Y at columns 0,6 replaced by M. Those are multiples of 3. Yes.

So rule holds for Example 2 as well.

Thus the transformation rule: For each row, replace Y with M at columns that are multiples of 3 (i.e., columns 0,3,6,9,12,...). The grid width may vary. In Example 1, width 13. In Example 2, width 11? Let's check: Row1 has 11 entries: . Y . Y . Y . Y . Y . (positions 0-10).

We need to solve a grid transformation puzzle. We have a metaphorical description: "Three lanes of golden runners: a full center lane and two flanking lanes with staggered positions, offset from one another. What to do: A periodic strobe paints certain runners magenta. The center lane catches it most often. The outer lanes catch it at half the frequency, only where runners happen to stand at the right beat. Grid details: Three horizontal rows. Center is solid golden. Outer rows alternate golden and empty in opposite patterns. Magenta replaces some golden cells at regular intervals."

We have training examples. Example 1:

Input:
```
Y . Y . Y . Y . Y . Y . Y
Y Y Y Y Y Y Y Y Y Y Y Y Y
. Y . Y . Y . Y . Y . Y .
```
Output:
```
M . Y . Y . M . Y . Y . M
M Y Y M Y Y M Y Y M Y Y M
. Y . M . Y . Y . M . Y .
```

Test Input:
```
. Y . Y . Y . Y . Y . Y . Y . Y .
Y Y Y Y Y Y Y Y Y Y Y Y Y Y Y Y Y
Y . Y . Y . Y . Y . Y . Y . Y . Y
```

We need to produce output grid.

We need to deduce transformation rule.

Let's analyze training example.

Input grid: 3 rows, each row length? Let's count: first row: "Y . Y . Y . Y . Y . Y . Y" that's 13 cells? Let's count: Y(1) space? Actually they separate by spaces. So row: Y . Y . Y . Y . Y . Y . Y. That's 13 cells: Y, ., Y, ., Y, ., Y, ., Y, ., Y, ., Y. So 13 cells.

Second row: Y Y Y Y Y Y Y Y Y Y Y Y Y: 13 Y's.

Third row: . Y . Y . Y . Y . Y . Y . : 13 cells: ., Y, ., Y, ., Y, ., Y, ., Y, ., Y, .? Wait there are 13 cells: ., Y, ., Y, ., Y, ., Y, ., Y, ., Y, .? Actually the pattern: . Y . Y . Y . Y . Y . Y . That's 13 cells: ., Y, ., Y, ., Y, ., Y, ., Y, ., Y, .? Wait we need to count: 1: ., 2: Y, 3: ., 4: Y, 5: ., 6: Y, 7: ., 8: Y, 9: ., 10: Y, 11: ., 12: Y, 13: .? But the pattern shows 13 cells: ., Y, ., Y, ., Y, ., Y, ., Y, ., Y, .? Actually there are 13 cells: ., Y, ., Y, ., Y, ., Y, ., Y, ., Y, .? Wait we need to check: The third row string: ". Y . Y . Y . Y . Y . Y ." That's 13 cells: ., Y, ., Y, ., Y, ., Y, ., Y, ., Y, .? Wait there are 13 cells: 1 ., 2 Y, 3 ., 4 Y, 5 ., 6 Y, 7 ., 8 Y, 9 ., 10 Y, 11 ., 12 Y, 13 .? Actually the pattern ends with a dot. So yes 13 cells.

So grid is 3x13.

Output grid: first row: "M . Y . Y . M . Y . Y . M" That's 13 cells: M, ., Y, ., Y, ., M, ., Y, ., Y, ., M. Wait there are 13 cells: M, ., Y, ., Y, ., M, ., Y, ., Y, ., M? Actually we need to count: 1 M, 2 ., 3 Y, 4 ., 5 Y, 6 ., 7 M, 8 ., 9 Y, 10 ., 11 Y, 12 ., 13 M. Yes.

Second row: "M Y Y M Y Y M Y Y M Y Y M" That's 13 cells: M, Y, Y, M, Y, Y, M, Y, Y, M, Y, Y, M.

Third row: ". Y . M . Y . Y . M . Y ." That's 13 cells: ., Y, ., M, ., Y, ., Y, ., M, ., Y, .? Wait we need to count: 1 ., 2 Y, 3 ., 4 M, 5 ., 6 Y, 7 ., 8 Y, 9 ., 10 M, 11 ., 12 Y, 13 .? Actually the pattern ends with a dot. So yes.

So transformation: In input, we have Y's in all cells except some '.' cells. In output, some Y's replaced by M (magenta). The pattern: In row 1, Y's at positions 1,3,5,7,9,11,13. In output, Y's at positions 3,5,9,11? Wait let's check: Row 1 output: M at positions 1,7,13; Y at positions 3,5,9,11; '.' at positions 2,4,6,8,10,12. So Y's at positions 3,5,9,11 remain Y; Y's at positions 1,7,13 replaced by M. So pattern: Y's at positions 1,7,13 replaced by M. Row 2: all Y's replaced by M at positions 1,4,7,10,13? Wait row 2 output: M Y Y M Y Y M Y Y M Y Y M. So Y's at positions 1,4,7,10,13 replaced by M. Row 3: Y's at positions 2,4,6,8,10,12? Wait row 3 output: . Y . M . Y . Y . M . Y . So Y's at positions 2,6,8,12? Wait let's list: positions: 1 ., 2 Y, 3 ., 4 M, 5 ., 6 Y, 7 ., 8 Y, 9 ., 10 M, 11 ., 12 Y, 13 . So Y's at positions 2,6,8,12 remain Y; Y's at positions 4,10 replaced by M. So pattern: Y's at positions 4,10 replaced by M.

So transformation: In each row, some Y's replaced by M at positions that follow a pattern. Let's analyze pattern across rows.

Row 1: M at positions 1,7,13. Row 2: M at positions 1,4,7,10,13. Row 3: M at positions 4,10.

We need to find rule: maybe it's a periodic strobe that paints certain runners magenta. The center lane catches it most often. The outer lanes catch it at half the frequency, only where runners happen to stand at the right beat.

Interpretation: We have three lanes: center lane (row 2) is full of runners (Y). Outer lanes (row 1 and row 3) have runners at alternating positions: row 1 has Y at odd positions (1,3,5,7,9,11,13). Row 3 has Y at even positions (2,4,6,8,10,12). Actually row 3 has Y at positions 2,4,6,8,10,12? Wait row 3 input: . Y . Y . Y . Y . Y . Y . So Y at positions 2,4,6,8,10,12. Yes.

So outer lanes have runners at alternating positions offset by one relative to each other. So row 1 has Y at odd positions; row 3 has Y at even positions.

Now the strobe: "periodic strobe paints certain runners magenta. The center lane catches it most often. The outer lanes catch it at half the frequency, only where runners happen to stand at the right beat." So the strobe is periodic; maybe it lights up at certain intervals. The center lane (row 2) has Y at

We need to solve a grid transformation puzzle. We have a metaphorical description: "Three rows of golden stage lights: a fully lit center row and two outer rows that alternate on/off in opposite patterns. Magenta gels replace golden lights at periodic intervals. The center row changes most often; the outer rows change at half the rate, only on lamps that are lit at the right cue points."

We have training example 1: Input grid and output grid. We need to deduce transformation rule.

Let's parse the training example.

Input grid:

Row1: "Y . Y . Y . Y . Y . Y . Y" (13 cells? Let's count: Y, ., Y, ., Y, ., Y, ., Y, ., Y, ., Y => 13 cells)
Row2: "Y Y Y Y Y Y Y Y Y Y Y Y Y" (13 Y's)
Row3: ". Y . Y . Y . Y . Y . Y ." (13 cells)

Output grid:

Row1: "M . Y . Y . M . Y . Y . M"
Row2: "M Y Y M Y Y M Y Y M Y Y M"
Row3: ". Y . M . Y . Y . M . Y ."

Let's check lengths: Row1 output: M, ., Y, ., Y, ., M, ., Y, ., Y, ., M => 13 cells. Row2: M, Y, Y, M, Y, Y, M, Y, Y, M, Y, Y, M => 13 cells. Row3: ., Y, ., M, ., Y, ., Y, ., M, ., Y, . => 13 cells.

So transformation: Input had Y's and . (black). Output replaced some Y's with M (magenta). The pattern: In row1, Y's at positions 1,3,5,7,9,11,13. Output: M at positions 1,7,13; Y at positions 3,5,9,11. So pattern: M at positions 1,7,13. Row3: Y's at positions 2,4,6,8,10,12. Output: M at positions 4,10. So pattern: M at positions 4,10. Row2: all Y's at positions 1-13. Output: M at positions 1,4,7,10,13. So pattern: M at positions 1,4,7,10,13.

So we need to deduce rule: maybe periodic intervals: every 6 cells? Let's examine positions: For row2, M at 1,4,7,10,13: difference 3 each time. So M at positions 1 + 3k for k=0..4. For row1, M at 1,7,13: difference 6 then 6. So M at positions 1 + 6k for k=0..2. For row3, M at 4,10: difference 6. So M at positions 4 + 6k for k=0..1.

So pattern: For each row, M at positions that are congruent to some offset modulo 6. Row2 offset 1 mod 3? Wait 1 mod 3? Actually 1,4,7,10,13 difference 3. So offset 1 mod 3. Row1 offset 1 mod 6? Actually 1,7,13 difference 6. So offset 1 mod 6. Row3 offset 4 mod 6? 4,10 difference 6. So offset 4 mod 6.

But maybe the rule: For each row, M at positions that are multiples of 3? Let's check: Row2: positions 1,4,7,10,13: these are 1 mod 3? 1 mod 3: 1,4,7,10,13 indeed. Row1: positions 1,7,13: these are 1 mod 6? But also 1 mod 3? 1 mod 3: 1,4,7,10,13. Row1 positions 1,7,13: 1 mod 3? 1 mod 3: 1,4,7,10,13. Row1 has 1,7,13 which are 1 mod 3 but missing 4,10. So maybe rule: For row1, M at positions that are 1 mod 6? But 1 mod 6: 1,7,13. Yes. Row3: M at 4,10: 4 mod 6. So maybe rule: For each row, M at positions that are 1 mod 6 for center row? Wait center row is row2. Outer rows are row1 and row3. The description: "Three rows of golden stage lights: a fully lit center row and two outer rows that alternate on/off in opposite patterns." So row2 is fully lit (all Y). Row1 and row3 alternate on/off in opposite patterns: row1 has Y at odd positions, row3 has Y at even positions. That matches input: row1 Y at odd positions, row3 Y at even positions. So outer rows alternate.

"Magenta gels replace golden lights at periodic intervals. The center row changes most often; the outer rows change at half the rate, only on lamps that are lit at the right cue points." So center row changes most often: maybe every 3 cells? Outer rows change at half the rate: maybe every 6 cells? And only on lamps that are lit at the right cue points: meaning only on Y cells (not on .). So for outer rows, M only on Y cells that are at positions that are multiples of 6? Let's check: Row1 Y at odd positions: 1,3,5,7,9,11,13. M at 1,7,13: these are 1 mod 6. Row3 Y at even positions: 2,4,6,8,10,12. M at 4,10: these are 4 mod 6. So yes, outer rows: M at positions that are 1 mod 6 for row1, 4 mod 6 for row3. That matches "half the rate" relative to center row: center row M at positions 1 mod 3. Outer rows M at positions 1 mod 6 or 4 mod 6. So rule: For center row, M at positions 1 mod 3. For outer rows, M at positions 1 mod 6 for row1, 4 mod 6 for row3. But why 4 mod 6 for row3? Because row3 Y at even positions, so the positions that are 4 mod 6 are even (4,10). So that matches.

But we need to confirm with training example: Row2 M at 1,4,7,10,13: yes 1 mod 3. Row1 M at 1,7,13: 1 mod 6. Row3 M at 4,10: 4 mod 6. So rule holds.

Now we need to apply to test input.

Test Input:

Row1: ". Y . Y . Y . Y . Y . Y . Y . Y ." (looks like 17 cells? Let's count: . Y . Y . Y . Y . Y . Y . Y . Y . => 17 cells. Actually pattern: . Y repeated 8 times? Let's count: positions: 1: ., 2: Y, 3: ., 4: Y, 5: ., 6: Y, 7: ., 8: Y, 9: ., 10: Y, 11: ., 12: Y, 13: ., 14: Y, 15: ., 16: Y, 17: . So yes 17 cells. Row1 has Y at even positions 2,4,6,8,10,12,14,16. Row2: "Y Y Y Y Y Y Y Y Y Y Y Y Y Y Y Y Y" (17 Y's). Row3: "Y . Y . Y . Y . Y . Y . Y . Y . Y" (17 cells). Row3 Y at odd positions 1,3,5,7,9,11,13,15,17. So outer rows alternate: row1 Y at even positions, row3 Y at od

We need to solve a grid transformation puzzle. We have training examples. We need to deduce the rule. Let's analyze.

We have a grid of 3 rows. Input and output grids are 3 rows each. The grid cells are either '.' (black) or a color letter: Y, M, etc. The transformation seems to replace some Y cells with M (magenta). The rule: "Magenta dahlias replace golden marigolds at periodic intervals. The center row is replanted most frequently; border rows receive dahlias at half the rate, only where flowers coincide with the longer cycle." So basically we have a pattern of Y cells in the input. The output has some Y cells replaced by M. The pattern: In the center row, all Y cells become M? Let's check.

Example 1:

Input:
Row1: Y . Y . Y . Y . Y . Y . Y
Row2: Y Y Y Y Y Y Y Y Y Y Y Y Y
Row3: . Y . Y . Y . Y . Y . Y .

Output:
Row1: M . Y . Y . M . Y . Y . M
Row2: M Y Y M Y Y M Y Y M Y Y M
Row3: . Y . M . Y . Y . M . Y .

Let's analyze each row.

Row1 input: Y . Y . Y . Y . Y . Y . Y
Indices: 0 1 2 3 4 5 6 7 8 9 10 11 12
Positions with Y: 0,2,4,6,8,10,12. Output row1: M . Y . Y . M . Y . Y . M
Positions: 0 M, 2 Y, 4 Y, 6 M, 8 Y, 10 Y, 12 M. So Y at positions 0,6,12 replaced by M. Y at positions 2,4,8,10 remain Y. So pattern: every 6 cells? Let's check: positions 0,6,12 difference 6. So maybe every 6 cells? But we need to check other rows.

Row2 input: all Y. Output row2: M Y Y M Y Y M Y Y M Y Y M
Indices 0-12. Output: M at 0,3,6,9,12. Y at 1,2,4,5,7,8,10,11. So M at positions 0,3,6,9,12. That's every 3 cells? Actually difference 3. So pattern: every 3 cells. Row3 input: . Y . Y . Y . Y . Y . Y . (positions 1,3,5,7,9,11). Output row3: . Y . M . Y . Y . M . Y . So M at positions 3,9. So pattern: every 6 cells? Actually difference 6. So row3: M at 3,9. So pattern: every 6 cells. Row1: M at 0,6,12. Row3: M at 3,9. Row2: M at 0,3,6,9,12. So row2 has M at every 3 cells. Row1 and Row3 have M at every 6 cells but offset: row1 at 0,6,12; row3 at 3,9. So row1 offset 0, row3 offset 3. So pattern: center row has M at every 3 cells; border rows have M at every 6 cells but offset by 3 relative to each other? Actually row1 offset 0, row3 offset 3. So they alternate.

Now Example 2:

Input:
Row1: . Y . Y . Y . Y . Y .
Row2: Y Y Y Y Y Y Y Y Y Y Y
Row3: Y . Y . Y . Y . Y . Y

Output:
Row1: . Y . M . Y . Y . M .
Row2: M Y Y M Y Y M Y Y M Y
Row3: M . Y . Y . M . Y . Y

Let's analyze.

Row1 input: . Y . Y . Y . Y . Y . (positions 1,3,5,7,9). Output row1: . Y . M . Y . Y . M . (positions 3,9 replaced by M). So M at positions 3,9. So pattern: every 6 cells? Actually difference 6. So row1 M at 3,9. Row3 input: Y . Y . Y . Y . Y . Y (positions 0,2,4,6,8,10). Output row3: M . Y . Y . M . Y . Y. So M at positions 0,6. So pattern: every 6 cells offset by 0. Row2 input: all Y. Output row2: M Y Y M Y Y M Y Y M Y. M at positions 0,3,6,9. So pattern: every 3 cells. So again center row M at every 3 cells. Border rows M at every 6 cells but offset: row1 offset 3, row3 offset 0. So same as example 1 but swapped? Wait example 1 had row1 offset 0, row3 offset 3. Example 2 has row1 offset 3, row3 offset 0. So the offset alternates between the two border rows. So the rule: In the border rows, M appears at every 6 cells, but the offset alternates between the two border rows. The center row has M at every 3 cells. The pattern of M positions in border rows depends on the relative positions of Y cells? Let's analyze more.

Example 3:

Input:
Row1: Y . Y . Y . Y . Y . Y
Row2: Y Y Y Y Y Y Y Y Y Y Y
Row3: . Y . Y . Y . Y . Y .

Output:
Row1: M . Y . Y . M . Y . Y
Row2: M Y Y M Y Y M Y Y M Y
Row3: . Y . M . Y . Y . M .

This is similar to example 1 but with one fewer Y in row1? Wait row1 input: Y . Y . Y . Y . Y . Y (positions 0,2,4,6,8,10). Output row1: M . Y . Y . M . Y . Y. M at positions 0,6. So M at 0,6. Row3 input: . Y . Y . Y . Y . Y . (positions 1,3,5,7,9). Output row3: . Y . M . Y . Y . M . M at 3,9. So again border rows M at every 6 cells offset by 0 for row1? Wait row1 M at 0,6 offset 0. Row3 M at 3,9 offset 3. So again offset alternates. So pattern: border rows M at every 6 cells, offset alternates between 0 and 3. Center row M at every 3 cells.

Now test input:

Row1: . Y . Y . Y . Y . Y . Y . Y . Y .
Row2: Y Y Y Y Y Y Y Y Y Y Y Y Y Y Y Y Y
Row3: Y . Y . Y . Y . Y . Y . Y . Y . Y

We need to produce output.

Let's analyze the pattern.

We need to deduce the rule precisely. Let's formalize.

We have a 3-row grid. The input has Y cells in a pattern: center row all Y. Border rows alternate Y and . (black). The pattern of Y in border rows is the same as the pattern of Y in the center row? Actually center row is all Y. Border rows alternate Y and . in antiphase: one border row starts with Y at index 0, the other starts with . at index 0. In example 1, row1 starts with Y at index 0, row3 starts with . at index 0. In example 2, row1 starts with . at index 0, row3 starts with Y at index 0. In example 3, row1 starts with Y at index 0, row3 starts with . at ind

We need to solve a grid transformation puzzle. The description: "What you see: A grey wall divides two rooms. On the left, a blue vault door has gaps cut into it — empty keyholes waiting. On the right, a colored key floats in darkness, its teeth shaped from a single vivid color. What to do: Slide the key into the lock. If every tooth fits perfectly into every keyhole — no extra teeth, no empty holes left over — the key merges with the vault door, filling each gap with its color. If the key doesn't match the lock, the vault stays sealed and unchanged, its empty keyholes still dark. Grid details: The grey wall always stands in the center, separating lock from key. The vault door is always built from blue steel and dark gaps. The key is always carved from a single color. What emerges is either a door transformed — blue and the key's color fused together — or the same cold, unturned lock."

We have training example 1:

Input:
```
B B B B X . . . .
B . . B X . M M .
B . . B X . M M .
B B B B X . . . .
```
Output:
```
B B B B
B M M B
B M M B
B B B B
```

So the input grid is 4x9? Let's parse: The input grid lines:

Line1: B B B B X . . . .  (9 columns)
Line2: B . . B X . M M .  (9 columns)
Line3: B . . B X . M M .  (9 columns)
Line4: B B B B X . . . .  (9 columns)

So 4 rows, 9 columns. The output grid is 4x4: B B B B / B M M B / B M M B / B B B B. So the output is the left side of the input? Actually the left side of the input is 4x4: columns 1-4. The right side of the input is columns 6-9? Wait, the input has a grey wall X at column 5. So the left side is columns 1-4, the right side is columns 6-9. The output is 4x4, which matches the left side. So the transformation seems to be: If the right side (key) matches the left side (lock) in some way, then the left side is replaced by the key's color in the keyhole positions. The keyhole positions are the '.' cells on the left side? Let's examine.

Left side (columns 1-4) of input:

Row1: B B B B
Row2: B . . B
Row3: B . . B
Row4: B B B B

So the left side is a blue square with a 2x2 hole in the middle (positions (2,2),(2,3),(3,2),(3,3) are '.'), representing keyholes. The right side (columns 6-9) of input:

Row1: . . . .
Row2: M M . .
Row3: M M . .
Row4: . . . .

So the right side is a 4x4 grid with a 2x2 block of M's in the top-left corner? Wait, row2 col6-9: M M . . ; row3 col6-9: M M . . ; row1 col6-9: . . . . ; row4 col6-9: . . . . . So the key is a 2x2 block of M's in the top-left corner of the right side. The key is a single color (M). The lock has a 2x2 hole. The key's shape matches the lock's shape? The key's shape is a 2x2 block of M's. The lock's shape is a 2x2 hole. So the key fits into the lock. The rule: If the key shape matches the lock shape exactly (i.e., the positions of non-'.' cells in the key correspond to the positions of '.' cells in the lock), then the lock's '.' cells are replaced by the key's color. The output shows the left side with the '.' replaced by M's. Indeed, output left side: B B B B / B M M B / B M M B / B B B B. So the '.' cells replaced by M's. The rest of the left side remains B. The right side is removed. The output is just the left side after transformation.

If the key does not match the lock shape, then the lock remains unchanged. The output would be the same as the left side? But the example shows a match.

We need to apply this rule to the test input.

Test Input:
```
B B B B X R . . .
. B B . X R R R R
. B B . X R . . .
. . . . X . . . .
```

Let's parse the test input. It's 4 rows, 9 columns. Let's index columns 1-9.

Row1: B B B B X R . . .
Row2: . B B . X R R R R
Row3: . B B . X R . . .
Row4: . . . . X . . . .

So left side columns 1-4: 
Row1: B B B B
Row2: . B B .
Row3: . B B .
Row4: . . . .

Right side columns 6-9: 
Row1: . . . .
Row2: R R R R
Row3: . . . .
Row4: . . . .

Wait, but we need to check: The right side is columns 6-9. Let's list them:

Row1: columns 6-9: R . . .? Wait, row1: B B B B X R . . . . Actually row1 has 9 columns: B B B B X R . . . . Wait, that's 10 columns? Let's count: B(1) B(2) B(3) B(4) X(5) R(6) .(7) .(8) .(9) .(10). Actually the input shows 9 columns? Let's count again: "B B B B X R . . ." That's 9 tokens: B, B, B, B, X, R, ., ., . . Wait, that's 9 tokens: B, B, B, B, X, R, ., ., . . Actually that's 9 tokens: B, B, B, B, X, R, ., ., . . Wait, we need to count: B(1) B(2) B(3) B(4) X(5) R(6) .(7) .(8) .(9). So there are 9 columns. So the right side is columns 6-9: R . . .? Wait, columns 6-9: column6=R, column7=., column8=., column9=.. So right side is R . . .? Actually row1: columns 6-9: R . . . (R at col6, . at col7, . at col8, . at col9). So right side row1: R . . . (4 cells). Row2: . B B . X R R R R. Let's parse row2: . B B . X R R R R. That's 9 tokens: .(1) B(2) B(3) .(4) X(5) R(6) R(7) R(8) R(9). So right side row2: columns 6-9: R R R R. Row3: . B B . X R . . . . Wait, row3: . B B . X R . . . . Actually row3: . B B . X R . . . . That's 9 tokens: .(1) B(2) B(3)

We need to solve a grid transformation puzzle. The description: "What you see: A blue tissue sample with empty receptor cavities sits beside a colored molecular cluster, separated by a grey membrane wall. What to do: If every colored molecule aligns precisely with every cavity in the tissue, the molecules bind and fill the receptors. If even one molecule has no matching cavity or one cavity has no molecule, the tissue rejects the cluster entirely. Grid details: The left 4x4 region is the tissue; black cells are receptor cavities. The right 4x4 region holds the molecular cluster. The grey column is the membrane. Output is the 4x4 tissue, either filled or unchanged."

We have training examples. Let's parse them.

Example 1 Input:
```
B B B B X . . . .
B . . B X . M M .
B . . B X . M M .
B B B B X . . . .
```
So it's a 4x4 left side (tissue) and 4x4 right side (molecule cluster). The grey column X is the membrane. The left side is all B except some '.' cells. The right side has '.' and 'M' cells. The output is:
```
B B B B
B M M B
B M M B
B B B B
```
So the output is the left side but with '.' replaced by M where there was M on the right side? Wait, let's analyze.

Left side (tissue) grid (4x4):
Row1: B B B B
Row2: B . . B
Row3: B . . B
Row4: B B B B

Right side (molecule cluster) grid (4x4):
Row1: . . . .
Row2: . M M .
Row3: . M M .
Row4: . . . .

So the right side has M in positions (row2,col2),(row2,col3),(row3,col2),(row3,col3). The left side has '.' in those same positions. The output shows B M M B in rows 2 and 3. So the '.' cells in tissue that correspond to M cells in cluster become M. So the rule: If the cluster has a colored molecule in a position that matches a cavity ('.') in tissue, then the tissue cell becomes that color. But the description says: "If every colored molecule aligns precisely with every cavity in the tissue, the molecules bind and fill the receptors. If even one molecule has no matching cavity or one cavity has no molecule, the tissue rejects the cluster entirely." So we need to check if the cluster's colored cells exactly match the tissue's cavities. That is, the set of positions of '.' in tissue must equal the set of positions of colored cells in cluster. If yes, then fill the tissue with those colors. If not, output unchanged tissue.

In Example 1, the tissue cavities are exactly the positions of M in cluster. So the cluster matches exactly. So we fill tissue with M at those positions. The output shows B M M B in rows 2 and 3. So that matches.

Example 2 Input:
```
B B B B X R R . .
B . . B X R R . .
B . . B X . . . .
B B B B X . . . .
```
Let's parse left side tissue (4x4):
Row1: B B B B
Row2: B . . B
Row3: B . . B
Row4: B B B B

Right side cluster (4x4):
Row1: R R . .
Row2: R R . .
Row3: . . . .
Row4: . . . .

So cluster has R in positions (row1,col1),(row1,col2),(row2,col1),(row2,col2). Tissue has '.' in positions (row2,col2),(row2,col3),(row3,col2),(row3,col3). Wait, tissue '.' positions: row2 col2, row2 col3, row3 col2, row3 col3. Cluster colored cells: row1 col1, row1 col2, row2 col1, row2 col2. They don't match. So the cluster does not align precisely with cavities. So the tissue rejects cluster entirely. So output is unchanged tissue: same as left side. Output given:
```
B B B B
B . . B
B . . B
B B B B
```
Yes.

So the rule: If the set of positions of colored cells in cluster equals the set of '.' cells in tissue, then fill tissue with those colors. Else output unchanged tissue.

But we need to consider that the cluster may have colored cells that are not '.' in tissue, or tissue may have '.' that are not colored in cluster. In either case, reject.

Also, the cluster may have multiple colors? In example 1, cluster had only M. In example 2, cluster had only R. But the description says "colored molecules" could be multiple colors. But the rule likely still applies: each colored molecule must align with a cavity. But if there are multiple colors, we need to fill each cavity with the color of the molecule that aligns. But if there is a mismatch, reject.

Also, the cluster may have colored cells that are not '.' in tissue. That would be a mismatch. So we need to check that for all positions (i,j) in 4x4, cluster[i][j] is either '.' or a color. Tissue[i][j] is either B or '.'.

We need to check that for all positions, cluster[i][j] is '.' if tissue[i][j] is B, and cluster[i][j] is a color if tissue[i][j] is '.'? Actually, the rule: "If every colored molecule aligns precisely with every cavity in the tissue, the molecules bind and fill the receptors. If even one molecule has no matching cavity or one cavity has no molecule, the tissue rejects the cluster entirely." So we need to check that the set of colored cells in cluster equals the set of cavities in tissue. That means: For each position (i,j), cluster[i][j] is colored if and only if tissue[i][j] is '.'.

Thus, we need to check that cluster[i][j] is '.' when tissue[i][j] is B, and cluster[i][j] is colored when tissue[i][j]

We need to solve a grid transformation puzzle. The description: "You are solving a grid transformation puzzle. You are given a metaphorical description of the transformation, training examples, and a test input grid.

Color key: .=black B=blue R=red G=green Y=yellow X=grey M=magenta O=orange A=azure W=maroon

## Metaphorical Description

What you see: A blue celestial body with exposed bright patches sits beside a colored shadow pattern, divided by a grey orbital plane.
What to do: If the shadow fills every exposed patch exactly, the color of the shadow replaces the brightness. If alignment is off, the celestial body appears as it was before the transit.
Grid details: Left 4x4 is the body. Right 4x4 is the shadow. Grey column is the orbital divider. Output is 4x4.

Before predicting the output, perform a Conceptual Digestion:
1. Identify the CAST: What roles do different grid elements play?
2. Identify the AFFORDANCES: What can each element do or have done to it?
3. Identify the TRANSFORMATION RULE: What is the precise rule that maps input to output?

Then apply the rule to the test input to predict the output grid.

## Training Examples

Example 1:
Input:
B B B B X . . . .
B . . B X . M M .
B . . B X . M M .
B B B B X . . . .
Output:
B B B B
B M M B
B M M B
B B B B

Test Input:
B B B B X R . . .
. B B . X R R R R
. B B . X R . . .
. . . . X . . . .

Think step by step. After your reasoning, you MUST write out the complete predicted output grid using these single-character color codes:
Color key: .=black B=blue R=red G=green Y=yellow X=grey M=magenta O=orange A=azure W=maroon

At the very end of your response, write the complete output grid inside a clearly labeled block like this:
ANSWER:
... etc"

We need to produce the output grid for the test input. We have one training example. We need to deduce the transformation rule.

Let's parse the training example.

Input grid: 4x4 left side (body) and 4x4 right side (shadow). There is a grey column X dividing them. So the input is 4x4 left, 1 column X, 4x4 right. So total width 9 columns? Actually 4+1+4=9. Height 4 rows.

Input example 1:

Row1: B B B B X . . . .
Row2: B . . B X . M M .
Row3: B . . B X . M M .
Row4: B B B B X . . . .

So left side (body) is 4x4:

Row1: B B B B
Row2: B . . B
Row3: B . . B
Row4: B B B B

Right side (shadow) is 4x4:

Row1: . . . .
Row2: . M M .
Row3: . M M .
Row4: . . . .

Output grid: 4x4:

Row1: B B B B
Row2: B M M B
Row3: B M M B
Row4: B B B B

So transformation: The body is a blue square with a central 2x2 area of '.' (black). The shadow has a 2x2 area of 'M' (magenta) in the same central location. The output replaced the '.' in the body with 'M' from the shadow. The rest of the body remains unchanged. So rule: For each cell in the body that is '.' (black), if the corresponding cell in the shadow is a color (not '.'), then replace the '.' with that color. If the shadow cell is '.' (black), keep the body cell as is. But the description says: "If the shadow fills every exposed patch exactly, the color of the shadow replaces the brightness. If alignment is off, the celestial body appears as it was before the transit." So maybe the rule is: For each '.' cell in the body, if the shadow cell is a color, replace it. But if the shadow cell is '.' (black), keep the body cell. But the description says "If the shadow fills every exposed patch exactly" meaning if the shadow covers all '.' cells? But in example, the shadow covers exactly the '.' cells. So the output replaced them. If the shadow does not cover all '.' cells, maybe the body remains unchanged? But we only have one example.

Let's analyze the test input.

Test Input:

Row1: B B B B X R . . .
Row2: . B B . X R R R R
Row3: . B B . X R . . .
Row4: . . . . X . . . .

So left side (body) 4x4:

Row1: B B B B
Row2: . B B .
Row3: . B B .
Row4: . . . .

Right side (shadow) 4x4:

Row1: R . . .
Row2: R R R R
Row3: R . . .
Row4: . . . .

Wait, we need to parse carefully: The input lines:

"B B B B X R . . ."
". B B . X R R R R"
". B B . X R . . ."
". . . . X . . . ."

So each row has 9 tokens: 4 body, 1 X, 4 shadow. Let's split:

Row1: body: B B B B; X; shadow: R . . .
Row2: body: . B B .; X; shadow: R R R R
Row3: body: . B B .; X; shadow: R . . .
Row4: body: . . . .; X; shadow: . . . .

Yes.

So body grid:

Row1: B B B B
Row2: . B B .
Row3: . B B .
Row4: . . . .

Shadow grid:

Row1: R . . .
Row2: R R R R
Row3: R . . .
Row4: . . . .

We need to produce output 4x4.

We need to deduce rule. Let's analyze the body: It is a blue square with some '.' cells. The body has a pattern: top row all B. Row2: '.' at col1, B at col2, B at col3, '.' at col4. Row3: same as row2. Row4: all '.'.

Shadow: Row1: R at col1, '.' at col2, '.' at col3, '.' at col4. Row2: R at all 4 columns. Row3: R at col1, '.' at col2, '.' at col3, '.' at col4. Row4: all '.'.

So the shadow covers some cells: It covers a vertical line at col1 (rows1-3) with R, and a horizontal line at row2 (cols1-4) with R. So the shadow shape i

We need to solve a puzzle. The description: "You are solving a grid transformation puzzle. You are given a metaphorical description of the transformation, training examples, and a test input grid.

## Metaphorical Description

What you see: A blue circuit board with empty sockets sits beside colored components on a grey anti-static mat.
What to do: If every component aligns with a socket and every socket gets a component, the board powers up and the components appear in place. Mismatch means the board stays in its original unpowered state.
Grid details: Left 4x4 is the board. Right 4x4 is the component tray. Grey column is the divider. Output is 4x4.

Before predicting the output, perform a Conceptual Digestion:
1. Identify the CAST: What roles do different grid elements play?
2. Identify the AFFORDANCES: What can each element do or have done to it?
3. Identify the TRANSFORMATION RULE: What is the precise rule that maps input to output?

Then apply the rule to the test input to predict the output grid.

## Training Examples

Example 1:
Input:
B B B B X . . . .
B . . B X . M M .
B . . B X . M M .
B B B B X . . . .
Output:
B B B B
B M M B
B M M B
B B B B

Example 2:
Input:
B B B B X R R . .
B . . B X R R . .
B . ... etc

We need to analyze the transformation.

We have a 4x4 board on left side, 4x4 component tray on right side, separated by a grey column X. The board is blue (B) and has empty sockets (represented by . maybe). The component tray has colored components (R, M, O, etc). The rule: If every component aligns with a socket and every socket gets a component, the board powers up and the components appear in place. Mismatch means the board stays in its original unpowered state.

So we need to interpret: The board is left 4x4. The component tray is right 4x4. The grey column X is a divider. The output is 4x4. The output likely is the board after powering up: the components from the tray are placed onto the board where there are sockets. But only if the alignment is perfect: each component must align with a socket and each socket must get a component. If not, the board stays unchanged (original board). So the output is either the board with components inserted or the board unchanged.

But we need to examine the training examples to confirm.

Example 1:

Input:
```
B B B B X . . . .
B . . B X . M M .
B . . B X . M M .
B B B B X . . . .
```
Let's parse: left 4x4 board:

Row1: B B B B
Row2: B . . B
Row3: B . . B
Row4: B B B B

Right 4x4 component tray:

Row1: . . . .
Row2: . M M .
Row3: . M M .
Row4: . . . .

So board has sockets at positions (2,2), (2,3), (3,2), (3,3) (assuming 1-indexed). The component tray has components at same positions: (2,2) M, (2,3) M, (3,2) M, (3,3) M. So each socket gets a component, and each component aligns with a socket. So board powers up: output board should have components placed in those sockets. The output given:

```
B B B B
B M M B
B M M B
B B B B
```

Yes, the output board has M's in those positions. So rule: if all sockets have components and all components align with sockets, then replace the sockets (.) with the component colors. The board remains otherwise unchanged.

Example 2:

Input:
```
B B B B X R R . .
B . . B X R R . .
B . . B X . . . .
B B B B X . . . .
```
Left board:

Row1: B B B B
Row2: B . . B
Row3: B . . B
Row4: B B B B

Right tray:

Row1: R R . .
Row2: R R . .
Row3: . . . .
Row4: . . . .

So components at (1,1) R, (1,2) R, (2,1) R, (2,2) R. But board sockets at (2,2), (2,3), (3,2), (3,3). So components are not aligned with sockets: they are in top-left corner of tray, not matching board sockets. So mismatch: board stays unchanged. Output:

```
B B B B
B . . B
B . . B
B B B B
```

Yes, unchanged board.

Example 3:

Input:
```
B B B B X . . . .
B . . . X . O O O
B . B B X . O . .
B . B . X . O . O
```
Left board:

Row1: B B B B
Row2: B . . . 
Row3: B . B B
Row4: B . B .

Right tray:

Row1: . . . .
Row2: . O O O
Row3: . O . .
Row4: . O . O

So board sockets: positions where board has '.'? Let's list board positions:

Row1: all B
Row2: B . . . (positions (2,2),(2,3),(2,4) are sockets)
Row3: B . B B (position (3,2) is socket)
Row4: B . B . (positions (4,2),(4,4) are sockets)

Right tray components: positions with O: (2,2),(2,3),(2,4),(3,2),(4,2),(4,4). So all board sockets have components? Let's check:

Board sockets: (2,2),(2,3),(2,4),(3,2),(4,2),(4,4). Tray components: same positions. Yes, all sockets have components. Also each component aligns with a socket. So board powers up: output board should have O's in those positions. Output given:

```
B B B B
B O O O
B O B B
B O B O
```

Yes, matches.

Thus rule: For each board cell that is '.' (socket), if the corresponding cell in the component tray (same row, same column) has a non-'.' component, then we replace the '.' with that component. But only if all sockets have components and all components align with sockets.

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A blue enchanted mask with carved rune-slots faces a set of colored counter-sigils across a grey altar stone. What to do: If every counter-sigil corresponds to a rune-slot and every slot is matched, the sigils fill the mask and transform it. Imperfect alignment leaves the mask cursed and unchanged. Grid details: Left 4x4 is the mask. Right 4x4 is the sigil array. Grey column is the altar. Output is 4x4."

We have training example 1. Input grid: 4x4 left mask, 4x4 right sigil array, grey column between them. The input grid is 4x4 left, then X column, then 4x4 right. The output is 4x4. We need to deduce transformation rule.

Let's parse training example 1.

Input:

```
B B B B X . . . .
B . . B X . M M .
B . . B X . M M .
B B B B X . . . .
```

So left 4x4 mask:

Row1: B B B B
Row2: B . . B
Row3: B . . B
Row4: B B B B

Right 4x4 sigil array:

Row1: . . . .
Row2: M M . .
Row3: M M . .
Row4: . . . .

Grey column X between them.

Output:

```
B B B B
B M M B
B M M B
B B B B
```

So output mask is same as left mask but with some cells changed: the '.' cells in the mask (positions (2,2),(2,3),(3,2),(3,3)) are replaced by M from the sigil array. The sigil array had M in those positions. So transformation: fill the mask's empty cells with corresponding sigil colors if they match? But we need to check rule: "If every counter-sigil corresponds to a rune-slot and every slot is matched, the sigils fill the mask and transform it. Imperfect alignment leaves the mask cursed and unchanged." So maybe the rule: For each empty cell in mask ('.'), if the corresponding cell in sigil array has a color (not '.'), then fill mask cell with that color. But also maybe need to check that all empty cells are filled? In example, all empty cells were filled. But what if some empty cells remain '.'? Then maybe output unchanged? But we only have one training example.

Let's analyze the test input.

Test Input:

```
B B B B X R . . .
. B B . X R R R R
. B B . X R . . .
. . . . X . . . .
```

So left mask:

Row1: B B B B
Row2: . B B .
Row3: . B B .
Row4: . . . .

Right sigil array:

Row1: R . . .
Row2: R R R R
Row3: R . . .
Row4: . . . .

We need to produce output 4x4.

We need to deduce rule precisely. Let's analyze the metaphor: "blue enchanted mask with carved rune-slots faces a set of colored counter-sigils across a grey altar stone." So left mask is blue (B) with carved rune slots ('.' maybe). Right sigil array is colored counter-sigils (R, M, etc). Grey column is altar. "If every counter-sigil corresponds to a rune-slot and every slot is matched, the sigils fill the mask and transform it. Imperfect alignment leaves the mask cursed and unchanged." So maybe the rule: For each slot in mask ('.'), there must be a corresponding sigil in the same relative position in the sigil array. If all slots are matched (i.e., all '.' in mask have a non-'.' in sigil array), then fill them. If any slot is unmatched (i.e., mask '.' but sigil '.'), then output unchanged (i.e., same as input mask). But we need to confirm with example: In example 1, mask had 4 '.' cells. Sigil array had M in those positions. So all matched. So output mask had those cells replaced by M. Good.

Now test input: mask has '.' cells at positions: (2,1),(2,4),(3,1),(3,4),(4,1),(4,2),(4,3),(4,4). That's 8 empty cells. Sigil array has R at positions: (1,1),(2,1),(2,2),(2,3),(2,4),(3,1). Wait let's list:

Sigil array:

Row1: R . . .
Row2: R R R R
Row3: R . . .
Row4: . . . .

So positions with R: (1,1),(2,1),(2,2),(2,3),(2,4),(3,1). That's 6 R's. So there are 6 non-'.' cells in sigil array. But mask has 8 '.' cells. So not all mask slots have a sigil. So according to rule, output should be unchanged mask? But we need to check if maybe the rule is different: maybe we only fill those slots that have a matching sigil, but if any slot is unmatched, we leave the mask unchanged entirely (no changes). But the phrase "If every counter-sigil corresponds to a rune-slot and every slot is matched, the sigils fill the mask and transform it. Imperfect alignment leaves the mask cursed and unchanged." That suggests that if not all slots are matched, the mask remains unchanged. So output should be same as input mask: B B B B / . B B . / . B B . / . . . . . But we need to confirm if there is any other nuance: maybe the rule is that we only fill the mask if the sigil array exactly matches the mask's empty cells pattern (i.e., same shape). But in example 1, the sigil array had M in the same shape as the mask's empty cells. In test input, the sigil array has R in some positions but not all. So not matching shape. So output unchanged.

But we need to check if there might be other transformation: maybe we need to rotate or reflect the sigil array to match the mask? But the description says "counter-sigils across a grey altar stone." The sigil array is across the altar. The mask faces the sigil array. So maybe the

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A blue dance formation with open positions faces colored dancers waiting across a grey stage divide. What to do: If every dancer finds an open position and every position has a dancer, partners join and color fills the formation. If not, the original formation holds. Grid details: Left 4x4 is the formation. Right 4x4 is the waiting dancers. Grey column is the divide. Output is 4x4."

We have training example 1: Input grid 8x4? Wait: Input: 
```
B B B B X . . . .
B . . B X . M M .
B . . B X . M M .
B B B B X . . . .
```
So it's 4 rows, 8 columns. The left 4 columns are formation, right 4 columns are waiting dancers. The grey column is the divide: X column? Actually the X column is the grey column dividing left and right. In the input, we see X at column 5? Wait: The input shows "B B B B X . . . ." So columns: 1-4: B B B B; column 5: X; columns 6-8: . . . .? Wait there are 8 columns: B B B B X . . . . That's 9 tokens? Let's count: B(1) B(2) B(3) B(4) X(5) .(6) .(7) .(8) .(9). Actually there are 9 tokens. But the grid is 4x9? But the description says left 4x4 is formation, right 4x4 is waiting dancers, grey column is divide. So total width 4+1+4=9 columns. Yes, 9 columns. So the grid is 4 rows x 9 columns. The left 4 columns (1-4) are formation, column 5 is X dividing, columns 6-9 are waiting dancers.

In the example, the left formation is all B's in first row, B's in last row, and B's in first column? Wait: Let's parse the input:

Row1: B B B B X . . . .
Row2: B . . B X . M M .
Row3: B . . B X . M M .
Row4: B B B B X . . . .

So left 4 columns: 
Row1: B B B B
Row2: B . . B
Row3: B . . B
Row4: B B B B

So left formation is a blue border: a 4x4 square of B's with interior empty (.). So it's a blue ring.

Right 4 columns: columns 6-9: 
Row1: . . . .
Row2: . M M .
Row3: . M M .
Row4: . . . .

So right side has a 2x2 block of M's in the middle (rows 2-3, columns 7-8). So the waiting dancers are M's.

The output is:
```
B B B B
B M M B
B M M B
B B B B
```
So the output is a 4x4 grid: the left formation but with the interior replaced by M's. So the M's from the right side moved into the interior of the left formation, filling the open positions. The rule: If every dancer finds an open position and every position has a dancer, partners join and color fills the formation. If not, the original formation holds.

So we need to interpret: The left formation is a shape of B's with open positions (.). The right side has some colored dancers (M's). The rule: If the number of dancers equals the number of open positions, and each open position can be matched with a dancer, then the formation is filled with the color of the dancers. But if not, the formation remains unchanged.

In example 1, the left formation had 4x4 border of B's, interior 2x2 open positions (4 open positions). The right side had exactly 4 M's. So the condition is satisfied: each open position gets a dancer. So the interior becomes M's. The output is the left formation with interior replaced by M's.

Now we need to apply to test input:

Test Input:
```
B B B B X R . . .
. B B . X R R R R
. B B . X R . . .
. . . . X . . . .
```
Let's parse: 4 rows, 9 columns. Left 4 columns: formation. Column 5: X. Right 4 columns: waiting dancers.

Row1: B B B B X R . . .
Row2: . B B . X R R R R
Row3: . B B . X R . . .
Row4: . . . . X . . . .

So left formation: columns 1-4:

Row1: B B B B
Row2: . B B .
Row3: . B B .
Row4: . . . .

So left formation is a shape: top row all B's, second and third rows have B's in columns 2-3, bottom row all empty. So it's like a shape of B's forming a T shape? Let's draw:

Row1: B B B B
Row2: . B B .
Row3: . B B .
Row4: . . . .

So B's at positions: (1,1),(1,2),(1,3),(1,4),(2,2),(2,3),(3,2),(3,3). So 8 B's. The open positions inside the shape: The shape is not closed; there are open positions inside? Let's see: The shape is like a 4x4 grid with B's at top row, middle two rows have B's in columns 2-3, bottom row empty. So there are open positions at (2,1),(2,4),(3,1),(3,4),(4,1),(4,2),(4,3),(4,4). So 8 open positions. But some of those open positions might be outside the shape? The shape is not closed; it's like a T shape with missing corners. But the rule might consider open positions as those that are not B's within the left 4x4 grid. So there are 8 open positions.

Right side: columns 6-9:

Row1: R . . .
Row2: R R R R
Row3: R . . .
Row4: . . . .

So right side has R's at positions: (1,6),(2,6),(2,7),(2,8),(2,9),(3,6). So 6 R's. Wait, we need to check: The right side is 4 columns: columns 6,7,8,9. So positions:

Row1: col6=R, col7=., col8=., col9=.
Row2: col6=R, col7=R, col8=R, col9=R
Row3: col6=R, col7=., col8=., col9=.
Row4: col6=., col7=., col8=., col9=.

So 6 R's.

So left formation has 8 open positions, right side has 6 R's. So the number of dancers (6) is less than the number of open positions (8). So the condition "If every dancer finds an

## Metaphorical Description

What you see: A blue rock formation with hollow chambers sits beside a colored magma flow pattern, divided by a grey fault line.
What to do: If every magma channel maps to a chamber and every chamber has a channel, the lava fills the voids with color. Incomplete alignment means the rock stays cool and unchanged.
Grid details: Left 4x4 is the rock. Right 4x4 is the magma map. Grey column is the fault line. Output is 4x4.

Before predicting the output, perform a Conceptual Digestion:
1. Identify the CAST: What roles do different grid elements play?
2. Identify the AFFORDANCES: What can each element do or have done to it?
3. Identify the TRANSFORMATION RULE: What is the precise rule that maps input to output?

Then apply the rule to the test input to predict the output grid.

## Training Examples

Example 1:
Input:
B B B B X . . . .
B . . B X . M M .
B . . B X . M M .
B B B B X . . . .
Output:
B B B B
B M M B
B M M B
B B B B

Example 2:
Input:
B B B B X R R . .
B . . B X R R . .
B . ... etc.

We need to analyze the transformation rule.

We have a 4x4 left side (rock) and 4x4 right side (magma). The grey column X is the fault line dividing them. The output is 4x4. The rule: "If every magma channel maps to a chamber and every chamber has a channel, the lava fills the voids with color. Incomplete alignment means the rock stays cool and unchanged."

Interpretation: The left side is rock with blue cells B and maybe other colors? The right side is magma flow pattern with colors like M, R, O, etc. The grey column X is a separator. The output is a 4x4 grid that presumably is the rock after lava fills the voids with color. The rule: For each cell in the rock that is a chamber (maybe a hole or empty space?), if there is a corresponding magma channel (color) that maps to that chamber, then the chamber gets filled with that color. But if not all chambers have a magma channel or not all magma channels map to a chamber, then the rock stays unchanged (i.e., output equals input rock). But the examples show that sometimes the output is changed.

Let's analyze the examples carefully.

Example 1:

Input grid (4x4 left, 4x4 right):

Left side (rock):
Row1: B B B B
Row2: B . . B
Row3: B . . B
Row4: B B B B

Right side (magma):
Row1: . . . .
Row2: . M M .
Row3: . M M .
Row4: . . . .

Grey column X is between them.

So the rock has a rectangular cavity in the center: a 2x2 area of '.' (empty). The magma side has a 2x2 area of 'M' in the same positions (rows 2-3, columns 2-3). So the magma channels align with the cavity. The output is:

B B B B
B M M B
B M M B
B B B B

So the cavity cells are filled with M. So the rule: If the magma side has a color in a cell that corresponds to a cavity cell in the rock, then fill that cavity cell with that color. But also we need to check that every magma channel maps to a chamber and every chamber has a channel. In this case, the magma side has exactly 4 cells of M, and the rock has exactly 4 cells of '.' (cavities). So it's a perfect mapping. So the output is the rock with cavities filled with M.

Example 2:

Input:

Left side (rock):
Row1: B B B B
Row2: B . . B
Row3: B . . B
Row4: B B B B

Right side (magma):
Row1: R R . .
Row2: R R . .
Row3: . . . .
Row4: . . . .

So the magma side has a 2x2 area of R in rows 1-2, columns 1-2. The rock has a 2x2 cavity in rows 2-3, columns 2-3. So the magma channels do not align with the cavity. The output is:

B B B B
B . . B
B . . B
B B B B

So the output is unchanged from the rock. So the rule: If the magma channels do not align with the cavities, then no filling occurs. But the description says "If every magma channel maps to a chamber and every chamber has a channel, the lava fills the voids with color. Incomplete alignment means the rock stays cool and unchanged." So indeed, if the mapping is incomplete or mismatched, no filling.

But we need to consider also the possibility that the magma side might have colors that are not M but other colors like R, O, etc. The output might fill cavities with those colors. But we need to check if the mapping is perfect: each magma channel must correspond to a cavity cell, and each cavity cell must have a magma channel. If that holds, then fill cavities with the magma colors. If not, output unchanged.

But we also need to consider that the rock might have other colors besides B and '.'? In the examples, the rock is only B and '.' (cavities). But maybe in other examples, the rock might have other colors? Let's check Example 3.

Example 3:

Input:

Left side (rock):
Row1: B B B B
Row2: B . . . 
Row3: B . B B
Row4: B . B .

Right side (magma):

What you see: A blue pastry mold with hollow spaces sits on one side of a grey countertop divider, and a colored batter shape sits on the other.
What to do: If the batter's shape is a perfect negative of the mold's hollows, pour it in and the color fills the gaps. If the shapes don't match perfectly, the mold remains unfilled.

ANSWER:

We need to produce the output grid for the test input.

We have a puzzle: left 4x4 is mold: blue walls, black hollows. Right 4x4 is batter: color cells (like red) and black cells (air). The rule: If the batter's shape is a perfect negative of the mold's hollows, pour it in and the color fills the gaps. If shapes don't match perfectly, the mold remains unfilled.

Interpretation: The mold is a shape of walls (blue) and hollows (black). The batter shape is a shape of color cells (like red) and air (black). The negative of the mold's hollows means that the shape of the color cells in the batter should exactly match the shape of the black cells in the mold, but inverted? Wait, "perfect negative of the mold's hollows" might mean that the shape of the batter's color cells is the complement of the mold's black cells. But the mold's black cells are hollows; the negative of that shape would be the shape of the black cells? Let's parse.

The metaphor: "If the batter's shape is a perfect negative of the mold's hollows, pour it in and the color fills the gaps." So the batter shape is a shape of color cells. The mold's hollows are black cells. The negative of the mold's hollows would be the shape of the black cells? Wait, negative shape: In image processing, negative of a shape means invert the shape: black becomes white, white becomes black. But here, the mold's hollows are black cells. The negative of that shape would be the shape of the black cells? Actually, if you take the mold's hollows shape (black cells), the negative would be the shape of the black cells? That seems trivial. But maybe they mean the shape of the batter's color cells should match the shape of the mold's black cells. But the phrase "negative" might mean that the shape of the batter's color cells is the complement of the mold's black cells: i.e., the batter's color cells fill the mold's black cells. But the phrase "negative" might mean that the shape of the batter's color cells is the same shape as the mold's black cells, but inverted orientation? Let's examine the training example.

Example 1 Input:
```
B B B B X . . . .
B . . B X . M M .
B . . B X . M M .
B B B B X . . . .
```
So left 4x4 (mold):
Row1: B B B B
Row2: B . . B
Row3: B . . B
Row4: B B B B

Right 4x4 (batter):
Row1: . . . .
Row2: . M M .
Row3: . M M .
Row4: . . . .

So mold has black cells at positions (2,2), (2,3), (3,2), (3,3). The batter has color cells (M) at positions (2,2), (2,3), (3,2), (3,3). So the shape of the batter's color cells exactly matches the shape of the mold's black cells. So the rule: If the shape of the batter's color cells matches the shape of the mold's black cells, then the color fills the gaps. The output is the mold with the color cells in the black hollows. The output grid is:

```
B B B B
B M M B
B M M B
B B B B
```

Yes, that matches the output. So the rule: If the shape of the batter's color cells exactly matches the shape of the mold's black cells, then the output is the mold with the color cells inserted into the black cells. If not, the mold remains unchanged (i.e., output is the mold unchanged). But the description says "If the shapes don't match perfectly, the mold remains unfilled." That means the output is the mol

We need to parse the puzzle. The description: "You are solving a grid transformation puzzle. You are given a metaphorical description of the transformation, training examples, and a test input grid.

Color key: .=black B=blue R=red G=green Y=yellow X=grey M=magenta O=orange A=azure W=maroon

## Metaphorical Description

What you see: A blue musical score with silent rests is separated by a grey bar line from a colored sequence of notes.
What to do: If every colored note corresponds to a rest in the score and every rest has a note, the notes fill the silences. If the correspondence is imperfect, the original score plays as written.
Grid details: Left 4x4 is the score (blue = sustained tones, black = rests). Right 4x4 is the note pattern. Grey column separates them. Output is the 4x4 score.

Before predicting the output, perform a Conceptual Digestion:
1. Identify the CAST: What roles do different grid elements play?
2. Identify the AFFORDANCES: What can each element do or have done to it?
3. Identify the TRANSFORMATION RULE: What is the precise rule that maps input to output?

Then apply the rule to the test input to predict the output grid.

## Training Examples

Example 1:
Input:
B B B B X . . . .
B . . B X . M M .
B . . B X . M M .
B B B B X . . . .
Output:
B B B B
B M M B
B M M B
B B B B

Test Input:
B B B B X R . . .
. B B . X R R R R
. B B . X R . . .
. . . . X . . . .

Think step by step. After your reasoning, you MUST write out the complete predicted output grid using these single-character color codes:
Color key: .=black B=blue R=red G=green Y=yellow X=grey M=magenta O=orange A=azure W=maroon

At the very end of your response, write the complete output grid inside a clearly labeled block like this:
ANSWER:
... etc"

We need to produce the output grid for the test input. Let's analyze the puzzle.

We have a 4x4 left side (score) and 4x4 right side (note pattern). The grey column X separates them. The left side is the "score" with blue B for sustained tones, black . for rests. The right side is a "note pattern" with colored notes (R, M, etc). The rule: "If every colored note corresponds to a rest in the score and every rest has a note, the notes fill the silences. If the correspondence is imperfect, the original score plays as written." So we need to fill the rests (.) in the left side with notes from the right side, but only if there's a perfect correspondence: each colored note corresponds to a rest in the score and every rest has a note. If not, we keep the original score unchanged.

But we need to interpret "corresponds" and "every rest has a note" precisely. Let's examine the training example.

Example 1 Input:

```
B B B B X . . . .
B . . B X . M M .
B . . B X . M M .
B B B B X . . . .
```

So left side (score) is 4x4:

Row1: B B B B
Row2: B . . B
Row3: B . . B
Row4: B B B B

Right side (note pattern) is 4x4:

Row1: . . . .
Row2: . M M .
Row3: . M M .
Row4: . . . .

So the right side has colored notes M in positions (row2, col2), (row2, col3), (row3, col2), (row3, col3). The left side has rests at positions (row2, col2), (row2, col3), (row3, col2), (row3, col3). So there is a perfect correspondence: each rest in the left side has a note in the right side, and each note in the right side corresponds to a rest in the left side. So we fill the rests with the notes. The output is:

```
B B B B
B M M B
B M M B
B B B B
```

Yes, that matches.

Now the test input:

```
B B B B X R . . .
. B B . X R R R R
. B B . X R . . .
. . . . X . . . .
```

Let's parse left side (score):

Row1: B B B B
Row2: . B B .
Row3: . B B .
Row4: . . . .

Right side (note pattern):

Row1: R . . .
Row2: R R R R
Row3: R . . .
Row4: . . . .

We need to determine if there's a perfect correspondence: each colored note corresponds to a rest in the score and every rest has a note. Let's list the positions of rests in the left side:

Left side rest positions (.):

Row1: none? Wait row1: B B B B, no rests.
Row2: positions (row2, col1) and (row2, col4) are rests.
Row3: positions (row3, col1) and (row3, col4) are rests.
Row4: positions (row4, col1), (row4, col2), (row4, col3), (row4, col4) are rests.

So total rests: 2 + 2 + 4 = 8 rests.

Now colored notes in right side: Let's list positions of colored notes (non-.):

Row1: (row1, col1) is R.
Row2: (row2, col1) R, (row2, col2) R, (row2, col3) R, (row2, col4) R.
Row3: (row3, col1) R.
Row4: none.

So total colored notes: 1 + 4 + 1 = 6 notes.

So there are 8 rests but only 6 notes. So not every rest has a note. So the correspondence is imperfect. According to the rule: "If the correspondence is imperfect, the original score plays as written." That means we keep the original score unchanged. So the output should be the left side unchanged: the 4x4 grid of the score.

But we need to confirm that the rule is indeed that simple. Let's double-check the description: "If every colored note corresponds to a rest in the score and every rest has a note, the notes fill the silences. If the correspond

We need to solve a grid transformation puzzle. The description: "What you see: A blue defensive wall with openings faces a colored attacking squad across a grey midfield line. What to do: If attackers perfectly occupy every gap in the wall, they break through and appear in those positions. If any gap is left unfilled or any attacker has no gap, the wall stands unchanged. Grid details: Left 4x4 is the defensive wall. Right 4x4 is the attacking formation. Grey column is the midfield. Output is the 4x4 wall, breached or intact."

We have training example 1. Input grid: 4x4 left side (wall) and 4x4 right side (attackers). There's a grey column X between them. The input grid is 4 rows, each row has 9 cells: 4 left, 1 X, 4 right. The output grid is 4x4: the wall after transformation.

We need to deduce rule: If attackers perfectly occupy every gap in the wall, they break through and appear in those positions. If any gap is left unfilled or any attacker has no gap, the wall stands unchanged.

Interpretation: The wall is blue cells B. The wall has openings: cells that are not B? In the left 4x4, there are B cells and maybe other colors? In example 1, left side: row1: B B B B; row2: B . . B; row3: B . . B; row4: B B B B. So the wall is a blue border with two openings in the middle (two columns). The right side: row1: . . . .; row2: M M . .; row3: M M . .; row4: . . . .? Wait let's parse example 1 input:

Input:
B B B B X . . . .
B . . B X . M M .
B . . B X . M M .
B B B B X . . . .

So each row has 9 cells: left 4, X, right 4. Let's index columns 1-4 left, 5 X, 6-9 right.

Row1: B B B B X . . . . => left: B B B B; right: . . . . (all black? Actually '.' is black). So row1 right side all black.

Row2: B . . B X . M M . => left: B . . B; right: . M M . (positions 6-9). So row2 right side: col6 '.', col7 'M', col8 'M', col9 '.'. So two magenta cells in middle.

Row3: B . . B X . M M . => same as row2.

Row4: B B B B X . . . . => left: B B B B; right: . . . . (all black).

So the right side has magenta cells in rows 2-3, columns 7-8. The left side has openings at columns 2-3 in rows 2-3. So the attackers (magenta) occupy exactly the openings in the wall. So rule: if attackers perfectly occupy every gap in the wall, they break through and appear in those positions. So the output should be the wall with magenta cells in the openings. Indeed output:

B B B B
B M M B
B M M B
B B B B

Yes, the output shows magenta cells in the openings. So rule: if the right side's colored cells exactly match the openings in the left side, then the left side's openings are replaced by those colors. If not, left side remains unchanged.

But we need to consider "If any gap is left unfilled or any attacker has no gap, the wall stands unchanged." So if the right side has some colored cells that don't match openings, or if some openings are not filled, then no change.

We need to apply to test input.

Test Input:
B B B B X R . . .
. B B . X R R R R
. B B . X R . . .
. . . . X . . . .

Let's parse. 4 rows, each 9 cells.

Row1: B B B B X R . . . => left: B B B B; right: R . . .? Wait columns 6-9: R . . .? Actually row1: after X, we have R . . .? Let's parse: "B B B B X R . . ." => left: B B B B; X; right: R . . .? But there are 4 cells after X: R, ., ., . So right side: col6 'R', col7 '.', col8 '.', col9 '.'. So row1 right side: R at col6, rest black.

Row2: ". B B . X R R R R" => left: . B B .; X; right: R R R R. So left side: col1 '.', col2 'B', col3 'B', col4 '.'; right side: col6 'R', col7 'R', col8 'R', col9 'R'.

Row3: ". B B . X R . . ." => left: . B B .; X; right: R . . .? Wait after X: R . . .? Actually row3: ". B B . X R . . ." => left: . B B .; X; right: R . . .? But there are 4 cells after X: R, ., ., . So right side: col6 'R', col7 '.', col8 '.', col9 '.'. So row3 right side: R at col6, rest black.

Row4: ". . . . X . . . ." => left: . . . .; X; right: . . . .? Actually after X: . . . .? Wait row4: ". . . . X . . . ." => left: . . . .; X; right: . . . .? But there are 4 cells after X: ., ., ., . So right side: all black.

So the left side (wall) is:

Row1: B B B B
Row2: . B B .
Row3: . B B .
Row4: . . . .

The right side (attackers) is:

Row1: R . . .
Row2: R R R R
Row3: R . . .
Row4: . . . .

We need to determine if the attackers perfectly occupy every gap in the wall. The wall has openings: cells that are not B. Let's identify openings in left side:

Row1: B B B B => no openings.
Row2: . B B . => openings at col1 and col4.
Row3: . B B . => openings at col1 and col4.
Row4: . . . . => openings at col1, col2, col3, col4.

So total openings: 2+2+4 = 8 openings.

Now the right side has colored cells: R at various positions. Let's list positions of R in right side:

Row1: col6 R
Row2: col6 R, col7 R, col8 R, col9 R
Row3: col6 R
Row4: none.

So there are 1+4+1+0 = 6 R cells.

But the rule says: "If attackers perfectly occupy every gap in the wall, they break through and appear in those positions.

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A blue landscape with patches of dry earth sits beside a colored rain pattern, divided by a grey cloud bank. What to do: If the rain pattern is the exact complement of the dry patches, the rain soaks in and colors the earth. Otherwise the land remains unchanged, as if the storm passed over. Grid details: Left 4x4 is the terrain. Right 4x4 is the rainfall pattern. Grey column is the cloud bank. Output is 4x4 terrain."

We have training example 1: Input grid 8x4? Actually 4x8? Let's parse.

Example 1 Input:
```
B B B B X . . . .
B . . B X . M M .
B . . B X . M M .
B B B B X . . . .
```
So it's 4 rows, 8 columns. The left 4 columns are the terrain (blue landscape with patches of dry earth). The right 4 columns are rainfall pattern. The middle column is grey cloud bank? Wait, the description says "Grey column is the cloud bank." But in the input, we see "X" in column 5? Actually the input has 8 columns: columns 1-4 are terrain, column 5 is X? Wait, the input shows "B B B B X . . . ." So row 1: B B B B X . . . . That's 9 entries? Let's count: B, B, B, B, X, ., ., ., . That's 9 columns. But the description says 4x4 left, 4x4 right, grey column in between. That would be 4+1+4 = 9 columns. Yes, 9 columns. So the grid is 4 rows, 9 columns. The left 4 columns are terrain, column 5 is X (grey cloud bank), columns 6-9 are rainfall pattern. So the input is 4x9.

The output is 4x4 terrain. The output grid is:

```
B B B B
B M M B
B M M B
B B B B
```

So the transformation: The left 4x4 terrain is updated based on the rainfall pattern. The rainfall pattern is 4x4 (columns 6-9). The grey column is X. The rule: "If the rain pattern is the exact complement of the dry patches, the rain soaks in and colors the earth. Otherwise the land remains unchanged, as if the storm passed over."

We need to interpret "dry patches" and "rain pattern complement." The left terrain has some cells that are not B? In the example, left terrain: row1: B B B B; row2: B . . B; row3: B . . B; row4: B B B B. So the left terrain has B cells (blue) and . cells (black). The right rainfall pattern: row1: . . . .; row2: M M . .; row3: M M . .; row4: . . . .? Wait, let's parse the input again:

Row1: B B B B X . . . . (columns 1-4: B B B B; column5: X; columns6-9: . . . .)
Row2: B . . B X . M M . (columns1-4: B . . B; column5: X; columns6-9: . M M .)
Row3: B . . B X . M M . (same as row2)
Row4: B B B B X . . . . (columns1-4: B B B B; columns6-9: . . . .)

So rainfall pattern: row1: . . . .; row2: . M M .; row3: . M M .; row4: . . . . (4x4). The left terrain: row1: B B B B; row2: B . . B; row3: B . . B; row4: B B B B.

The output: row1: B B B B; row2: B M M B; row3: B M M B; row4: B B B B.

So the output changed the . cells in the left terrain to M where the rainfall pattern had M? Actually the rainfall pattern had M in positions (row2, col7-8) and (row3, col7-8). The left terrain had . at positions (row2, col2-3) and (row3, col2-3). The output changed those . to M. So the rule: If the rainfall pattern has a color (M) at a position, and the left terrain has a dry patch (.) at the corresponding position, then the dry patch becomes that color. But the description says "If the rain pattern is the exact complement of the dry patches, the rain soaks in and colors the earth. Otherwise the land remains unchanged." So maybe the rule is: For each cell in the left terrain, if the corresponding cell in the rainfall pattern is the same color as the left terrain cell? Wait, the left terrain cell is either B or .; the rainfall pattern cell is either . or M. The complement of dry patches: The dry patches are the . cells. The complement of dry patches would be the cells that are not dry? But the rainfall pattern is the complement of the dry patches? Let's interpret: The left terrain has B cells (blue) and . cells (dry). The rainfall pattern has M cells (rain color) and . cells (no rain). The rule: If the rainfall pattern is the exact complement of the dry patches, the rain soaks in and colors the earth. That means: For each cell, if the left terrain cell is . (dry), then the rainfall pattern cell must be M (rain). And if the left terrain cell is B (blue), then the rainfall pattern cell must be . (no rain). That would be the complement: The rainfall pattern has M where the terrain has ., and . where the terrain has B. That is exactly the complement. In the example, the rainfall pattern is indeed the complement: For row2, col2-3: left terrain ., rainfall pattern M. For row2, col1 and col4: left terrain B, rainfall pattern . . Yes. For row3, same. For row1 and row4: left terrain B B B B, rainfall pattern . . . . (complement). So the rainfall pattern is the exact complement of the dry patches. So the rule triggers: The rain soaks in and colors the earth. So the output: The left terrain is updated: The dry patches (.) become the color of the rain (M). The B cells remain B. So the o

We need to solve a puzzle. The description: "You are solving a grid transformation puzzle. You are given a metaphorical description of the transformation, training examples, and a test input grid.

Color key: .=black B=blue R=red G=green Y=yellow X=grey M=magenta O=orange A=azure W=maroon

## Metaphorical Description

What you see: A blue fortress with structural weak points faces a colored siege formation across a grey no-man's-land.
What to do: If every siege weapon aligns with a weak point and every weak point faces a weapon, the walls fall and the color fills the breaches. Misalignment means the fortress stands.
Grid details: Left 4x4 is the fortress. Right 4x4 is the siege. Grey column is the buffer zone. Output is the 4x4 fortress.

Before predicting the output, perform a Conceptual Digestion:
1. Identify the CAST: What roles do different grid elements play?
2. Identify the AFFORDANCES: What can each element do or have done to it?
3. Identify the TRANSFORMATION RULE: What is the precise rule that maps input to output?

Then apply the rule to the test input to predict the output grid.

## Training Examples

Example 1:
Input:
B B B B X . . . .
B . . B X . M M .
B . . B X . M M .
B B B B X . . . .
Output:
B B B B
B M M B
B M M B
B B B B

Example 2:
Input:
B B B B X R R . .
B . . B X R R . .
B . ... etc.

We need to analyze the transformation rule.

We have a 4x4 fortress on the left side of the grid, a 4x4 siege on the right side, separated by a grey column X. The fortress is blue (B) with structural weak points indicated by '.'? The siege is colored (R, M, O, etc). The rule: "If every siege weapon aligns with a weak point and every weak point faces a weapon, the walls fall and the color fills the breaches. Misalignment means the fortress stands."

Interpretation: The fortress is a 4x4 grid of cells. The siege is a 4x4 grid of cells on the right side. The grey column X is a buffer zone. The fortress cells are either B (blue) or '.' (weak point). The siege cells are colored (R, M, O, etc) or '.' (empty). The rule: For each column (or maybe each row?) we check alignment: If a siege cell (colored) aligns with a weak point ('.') in the fortress, and every weak point faces a siege weapon, then the fortress walls fall and the color fills the breaches. That means the fortress cells that were weak points ('.') become the color of the siege weapon that aligns with them. The fortress cells that were originally B remain B? Or maybe they become the color of the siege weapon if the fortress falls? Let's examine training examples.

Example 1:

Input grid:

Row1: B B B B X . . . .
Row2: B . . B X . M M .
Row3: B . . B X . M M .
Row4: B B B B X . . . .

So left 4x4 fortress:

Row1: B B B B
Row2: B . . B
Row3: B . . B
Row4: B B B B

Right 4x4 siege:

Row1: . . . .
Row2: . M M .
Row3: . M M .
Row4: . . . .

So siege cells: only rows 2-3, columns 2-3 have M. Others are '.'.

Now output:

B B B B
B M M B
B M M B
B B B B

So fortress remains same except the weak points '.' in rows 2-3, columns 2-3 become M. So the rule: If a weak point aligns with a siege weapon, the weak point becomes that color. But we also need to check "every siege weapon aligns with a weak point and every weak point faces a weapon" condition. In this example, all siege weapons (M) align with weak points ('.') in fortress. And all weak points (there are 4 of them) face a siege weapon. So the fortress falls and the color fills the breaches. So the output is fortress with weak points replaced by the siege color.

Now Example 2:

Input:

Row1: B B B B X R R . .
Row2: B . . B X R R . .
Row3: B . . B X . . . .
Row4: B B B B X . . . .

So fortress:

Row1: B B B B
Row2: B . . B
Row3: B . . B
Row4: B B B B

Siege:

Row1: R R . .
Row2: R R . .
Row3: . . . .
Row4: . . . .

So siege weapons: R in rows 1-2, columns 1-2. Weak points: '.' in fortress at rows 2-3, columns 2-3. Wait fortress weak points: row2 col2, row2 col3, row3 col2, row3 col3. Siege weapons: row1 col1, row1 col2, row2 col1, row2 col2. So alignment: Siege weapons are not aligned with weak points. They are above them? Actually fortress is left side, siege is right side. The alignment might be vertical alignment: same row? Or same column? Let's think: The fortress is left 4x4, siege is right 4x4. The grey column X is between them. So the fortress cells are at positions (row, col) 1-4, 1-4. Siege cells are at positions (row, col) 1-4, 6-9? Actually the grid is 4x4 fortress, 1 column X, 4x4 siege. So the siege cells are offset horizontally by 5 columns relative to fortress. So alignment might be vertical alignment: same row. So a siege weapon aligns with a weak point if they are in the same row. But the fortress weak points are at columns 2-3. Siege weapons are at columns 1-2 relative to siege grid. So they are not aligned horizontally. But maybe alignment means that the siege weapon is in the same row and same column relative to the fortress? But the fortress and siege are separate, so maybe alignment m

We need to parse the puzzle. We have a grid transformation puzzle. The description: "What you see: A blue stage arrangement with empty marks sits beside colored understudies waiting in the wings, separated by a grey curtain. What to do: If every empty mark has a corresponding understudy and every understudy has an empty mark, the understudies take their positions. Otherwise the original arrangement holds. Grid details: Left 4x4 is the stage. Right 4x4 is the wing. Grey column is the curtain. Output is 4x4."

We have training example 1: Input grid 8x4? Wait: The input grid is 4x8? Let's examine.

Example 1 Input:

```
B B B B X . . . .
B . . B X . M M .
B . . B X . M M .
B B B B X . . . .
```

This appears to be 4 rows, each row has 8 columns: 4 left side (stage) + 1 grey column (curtain) + 4 right side (wing). So 4x8 grid. The left 4 columns are stage, right 4 columns wing, middle column is grey curtain (X). Output is 4x4 grid: presumably the stage after transformation.

The rule: "If every empty mark has a corresponding understudy and every understudy has an empty mark, the understudies take their positions. Otherwise the original arrangement holds."

Interpretation: The stage has some empty marks ('.') and some blue marks (B). The wing has some colored understudies (M, etc). The rule: If each empty mark on the stage has a corresponding understudy in the wing, and each understudy has an empty mark, then the understudies take their positions. That means the empty marks on the stage are replaced by the corresponding understudy colors from the wing. The wing empties? Or maybe the wing empties become empty? The output is 4x4 grid: presumably the stage after transformation. The wing is not output. So we only output the stage after transformation.

Thus the rule: For each empty cell '.' on the stage, we need to find a matching understudy in the wing. But what does "corresponding" mean? Possibly the same color? Or maybe each empty mark corresponds to a specific understudy color that matches the color of the empty mark? But empty marks are '.'; they don't have color. So maybe each empty mark corresponds to a specific understudy color that is present in the wing. But there may be multiple empty marks and multiple understudies. The rule says: "If every empty mark has a corresponding understudy and every understudy has an empty mark, the understudies take their positions." So we need a one-to-one mapping between empty marks and understudies. That means the number of empty marks on the stage equals the number of understudies in the wing. And each empty mark is replaced by the color of the corresponding understudy. But we need to decide which understudy goes to which empty mark. Possibly the mapping is by column? Or by row? Or by some pattern? Let's analyze the example.

Example 1 Input:

Row1: B B B B X . . . .
Row2: B . . B X . M M .
Row3: B . . B X . M M .
Row4: B B B B X . . . .

So stage (left 4 columns) is:

Row1: B B B B
Row2: B . . B
Row3: B . . B
Row4: B B B B

Wing (right 4 columns) is:

Row1: . . . .
Row2: . M M .
Row3: . M M .
Row4: . . . .

So there are 4 empty marks on the stage: positions (row2,col2), (row2,col3), (row3,col2), (row3,col3). There are 4 understudies in the wing: positions (row2,col6), (row2,col7), (row3,col6), (row3,col7). They are all M (magenta). So there are 4 understudies, all same color M. So the mapping is trivial: each empty mark gets M. The output is:

```
B B B B
B M M B
B M M B
B B B B
```

Yes, that matches: the empty marks replaced by M. So the rule: If the number of empty marks equals the number of understudies, and each understudy has a color, then each empty mark is replaced by the color of an understudy. But we need to decide mapping: maybe each empty mark gets the color of the corresponding understudy in the same row? Let's check: In row2, the empty marks at col2 and col3 correspond to understudies at col6 and col7. So mapping by row: each empty mark gets the color of the understudy in the same row. In row3, same. So mapping by row. But what if there are multiple colors? Let's examine test input.

Test Input:

```
B B B B X R . . .
. B B . X R R R R
. B B . X R . . .
. . . . X . . . .
```

Let's parse: 4 rows, 8 columns.

Row1: B B B B X R . . .
Row2: . B B . X R R R R
Row3: . B B . X R . . .
Row4: . . . . X . . . .

So stage (left 4 columns):

Row1: B B B B
Row2: . B B .
Row3: . B B .
Row4: . . . .

Wing (right 4 columns):

Row1: R . . .
Row2: R R R R
Row3: R . . .
Row4: . . . .

Wait, we need to check: The right 4 columns are columns 6-8? Actually the grid has 8 columns: columns 1-4 stage, column 5 is curtain (X), columns 6-8 wing? But there are 8 columns, so columns 6-8 are wing? But we have 4 columns for wing, but we only have 3 columns after the curtain? Let's check: The input row1: "B B B B X R . . ." That's 9 tokens? Wait, let's count: B, B, B, B, X, R, ., ., . That's 9 tokens. But the grid should be 8 columns: 4 stage + 1 curtain + 4 wing = 9 columns? Wait, 4+1+4 =

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A blue garden bed with patches of tilled soil sits beside colored seeds on a grey potting bench. What to do: If every seed aligns with tilled soil and every plot receives a seed, the garden blooms in color. If the match is imperfect, the bed stays as it was. Grid details: Left 4x4 is the garden bed. Right 4x4 is the seed tray. Grey column is the bench. Output is 4x4."

We have training examples. Let's parse them.

We have a 4x4 left side (garden bed) and a 4x4 right side (seed tray). The middle column is grey X. The input grid is 4x8? Actually 4 rows, 8 columns: left 4 columns, then X column, then right 4 columns. The output is 4x4.

We need to figure out transformation rule.

Let's analyze Example 1.

Example 1 Input:

Row1: B B B B X . . . .
Row2: B . . B X . M M .
Row3: B . . B X . M M .
Row4: B B B B X . . . .

So left 4x4 (garden bed) is:

Row1: B B B B
Row2: B . . B
Row3: B . . B
Row4: B B B B

Right 4x4 (seed tray) is:

Row1: . . . .
Row2: . M M .
Row3: . M M .
Row4: . . . .

So the seed tray has M in positions (row2, col2-3) and (row3, col2-3). The left side has B in all cells except the interior 2x2 (rows2-3, cols2-3) which are '.' (black). So the left side has a 2x2 interior of black cells. The right side has M in that same 2x2 area. So the seeds align with the tilled soil? Wait, the left side interior is black (maybe tilled soil). The right side has seeds M. So seeds align with tilled soil. The rule: If every seed aligns with tilled soil and every plot receives a seed, the garden blooms in color. If the match is imperfect, the bed stays as it was.

So we need to check if the seeds align with the tilled soil and every plot receives a seed. That means: For each cell in the left side that is '.' (tilled soil), there must be a seed in the corresponding cell in the right side. And for each cell in the right side that has a seed, the corresponding left side cell must be '.' (tilled soil). And also every plot receives a seed: meaning all '.' cells in left side must have a seed in right side? Or maybe all cells in left side must be covered by seeds? Let's parse.

In Example 1, left side has 4x4 = 16 cells. The interior 2x2 = 4 cells are '.'; the rest 12 cells are B. Right side has M in the same 2x2 cells, and '.' elsewhere. So the seeds align with tilled soil: yes. And every plot receives a seed: meaning all '.' cells in left side have a seed. Yes. So the transformation: The output is the garden bed with seeds replaced? Let's see output:

Output:
B B B B
B M M B
B M M B
B B B B

So the output is the left side but with the interior '.' replaced by M (the seed color). So basically, if the seeds align with tilled soil and every plot receives a seed, then the garden bed is updated: the '.' cells become the seed color. The rest remains B. So the output is left side with '.' replaced by seed color.

Now Example 2.

Input:

Row1: B B B B X R R . .
Row2: B . . B X R R . .
Row3: B . . B X . . . .
Row4: B B B B X . . . .

Left side:

Row1: B B B B
Row2: B . . B
Row3: B . . B
Row4: B B B B

Right side:

Row1: R R . .
Row2: R R . .
Row3: . . . .
Row4: . . . .

So seeds: R in positions (row1, col1-2) and (row2, col1-2). The left side has '.' in positions (row2, col2-3) and (row3, col2-3). Wait, left side interior '.' positions: row2 col2-3, row3 col2-3. Right side seeds are in row1 col1-2 and row2 col1-2. So they don't align: seeds are in top-left 2x2 of right side, but left side '.' are in bottom-left 2x2? Actually left side '.' positions: row2 col2-3, row3 col2-3. So they are in the left side's interior 2x2 but offset: left side '.' positions are at columns 2-3 (0-indexed 1-2). Right side seeds are at columns 1-2 (0-indexed 0-1). So they don't align. Also, not all '.' cells have seeds: left side '.' cells are 4 cells, but right side seeds are 4 cells but not in same positions. So the match is imperfect. According to rule, the bed stays as it was. So output should be the left side unchanged. Output:

B B B B
B . . B
B . . B
B B B B

Yes, matches output.

Now Example 3.

Input:

Row1: B B B B X . . . .
Row2: B . . . X . O O O
Row3: B . B B X . O . .
Row4: B . B . X . O . O

Left side:

Row1: B B B B
Row2: B . . .
Row3: B . B B
Row4: B . B .

Right side:

Row1: . . . .
Row2: . O O O
Row3: . O . .
Row4: . O . O

So seeds: O in row2 col2-4, row3 col2, row4 col2 and col4. Let's map coordinates: left side '.' positions: row2 col2-4 (positions 2-4?), row3 col2, row4 col2 and col4. Wait, left side '.' positions: row2 col2-4 (3 cells), row3 col2 (1 cell), row4 col2 and col4 (2 cells). So total 6 '.' cells. Right side seeds: row2 col2-4 (3 cells), row3 col2 (1 cell), row4 col2 and col4 (2 cells). So they align exactly. So the match is perfect. So output should be left side with '.' replaced by O. Let's check output:

Output:
B B B B
B O O O
B O B B
B O B O

Yes, matches.

So rule: For each test input, we need to check if the seed

We need to parse the puzzle. The description: "Two kingdoms sit on opposite sides of a golden bridge. The northern kingdom flies blue banners from some of its towers, while the southern kingdom lights red fires atop others. The darkness between them marks empty watchtowers where no one stands guard. What to do: The golden bridge opens and the two kingdoms merge their defenses. Any watchtower that had a blue banner flying OR a red fire burning sends a soldier to the unified army, marked in green. Only towers that were dark and abandoned in BOTH kingdoms remain empty in the new realm. Grid details: The world is a tall fortress split by a golden bridge spanning the full width. Above and below the bridge lie matching castle walls. The united army's banner—green against the darkness—flies only where at least one kingdom once kept watch."

So we have a grid transformation puzzle. The input grid has some colors: B, R, Y, ., etc. The output grid has G's and .s. The rule: For each cell, if either the cell in the northern part (above the bridge) or the southern part (below the bridge) had a B or R (blue or red), then output G. If both were empty (.), then output . (empty). But we need to confirm with training example.

Let's analyze Example 1.

Input grid: Provided as 10 rows? Let's parse.

Example 1 Input:
```
B B . .
B . B .
B B . B
B B B B
Y Y Y Y
R R . R
. . R .
. R . .
R . R .
```
Output:
```
G G . G
G . G .
G G . G
G G G G
```

Wait: The output grid is 4 rows? Actually output shows 4 rows of 4 columns each. But input grid is 10 rows of 4 columns each. So the transformation reduces the grid size? Let's examine.

Input grid: 10 rows, 4 columns. Output grid: 4 rows, 4 columns. So maybe the transformation merges the top 5 rows (northern kingdom) and bottom 5 rows (southern kingdom) into a single 4x4 grid? But 5+5=10 rows. But output has 4 rows. So maybe the golden bridge splits the grid into two halves: top half (rows 1-5) and bottom half (rows 6-10). Then we combine them by some rule: For each column, we combine the two halves? But output has 4 columns, same as input. So maybe we combine each column pair? Wait.

Let's analyze the input grid more carefully. The input grid has 10 rows, 4 columns. The first 5 rows (rows 1-5) are the northern kingdom? Actually the description says "Two kingdoms sit on opposite sides of a golden bridge." So the grid is split by a golden bridge spanning the full width. The golden bridge is maybe a row of Y's? In the input, row 5 is "Y Y Y Y". That might represent the golden bridge. So the top part (rows 1-4) is the northern kingdom, the bottom part (rows 6-10) is the southern kingdom. The golden bridge row (row 5) is Y Y Y Y. So the grid is 10 rows: 4 rows above the bridge, 1 row of Y's (bridge), 5 rows below the bridge. But the output grid is 4 rows. So maybe we ignore the bridge row and combine the two halves into a single grid of 4 rows? But we have 4 rows above the bridge and 5 rows below. So maybe we combine them by aligning them vertically? But we need to produce 4 rows output. So maybe we only consider the top 4 rows and bottom 4 rows? But bottom has 5 rows. So maybe we ignore the last row? Let's examine the input bottom part: rows 6-10:

Row 6: R R . R
Row 7: . . R .
Row 8: . R . .
Row 9: R . R .
Row 10: ??? Wait there are only 10 rows total. Actually we counted 10 rows: 1-10. Row 10 is "R R R ." Wait let's re-check the input lines:

Input lines:

1: B B . .
2: B . B .
3: B B . B
4: B B B B
5: Y Y Y Y
6: R R . R
7: . . R .
8: . R . .
9: R . R .
10: ??? Wait we have 10 lines? Let's count again:

The input block:

```
B B . .
B . B .
B B . B
B B B B
Y Y Y Y
R R . R
. . R .
. R . .
R . R .
```

That's 9 lines? Let's count: 1: B B . .; 2: B . B .; 3: B B . B; 4: B B B B; 5: Y Y Y Y; 6: R R . R; 7: . . R .; 8: . R . .; 9: R . R .; 10: ??? Wait we have 9 lines. Actually we counted 9 lines. Let's recount: The block shows 9 lines. Let's list them:

Line 1: B B . .
Line 2: B . B .
Line 3: B B . B
Line 4: B B B B
Line 5: Y Y Y Y
Line 6: R R . R
Line 7: . . R .
Line 8: . R . .
Line 9: R . R .

Yes, 9 lines. So the grid is 9 rows, 4 columns. The golden bridge row is row 5: Y Y Y Y. So top part: rows 1-4 (4 rows). Bottom part: rows 6-9 (4 rows). So both halves have 4 rows each. That matches the output grid of 4 rows. So the transformation merges the two halves (top and bottom) into a single 4x4 grid. The rule: For each cell position (row, column), if either the top cell or the bottom cell is B or R, then output G. If both are empty (.), then output . (empty). But we need to confirm with the example.

Let's compute the output for each cell:

We have top part (rows 1-4) and bottom part (rows 6-9). Let's index rows 1-4 top, 6-9 bottom. We'll align them row-wise: row 1 top with row 6 bottom? Wait we need to align them by row index relative to the bridge. The top part has 4 rows: rows 1-4. The bottom part has 4 rows: rows 6-9. So we can pair row 1 with row 6, row 2 with row 7, row 3 w

We need to solve a grid transformation puzzle. We have a metaphorical description: "two-chambered petri dish divided by a golden membrane. The upper culture shows cold-pigment colonies; the lower shows warm-pigment colonies. Empty sites are sterile. Fuse the two cultures through the membrane. Any site where at least one chamber harbored a living colony blooms into a hybrid organism of a novel hue. Sterile sites remain barren. Grid details: Output is a single 4×4 dish. Hybrid colonies appear where either parent culture was active. Empty where both were sterile."

We have training examples. Example 1: Input: a 8x? Wait, the input grid appears to be 8 rows? Let's parse.

Example 1 Input:
```
B B . .
B . B .
B B . B
B B B B
Y Y Y Y
R R . R
. . R .
. R . .
R . R .
```
Wait, that's 9 rows? Let's count: 1: B B . . ; 2: B . B . ; 3: B B . B ; 4: B B B B ; 5: Y Y Y Y ; 6: R R . R ; 7: . . R . ; 8: . R . . ; 9: R . R . . Wait, the last row has 5 entries? Actually "R . R ." is 4 entries. Let's re-evaluate: The input lines:

1. B B . .
2. B . B .
3. B B . B
4. B B B B
5. Y Y Y Y
6. R R . R
7. . . R .
8. . R . .
9. R . R .

But the last line "R . R ." has 4 entries. So we have 9 rows of 4 columns each. So the input is 9x4 grid. The output is 4x4 grid:

Output:
```
G G . G
G . G .
G G . G
G G G G
```

So the transformation: The input is 9x4 grid. The output is 4x4 grid. The description says: "Output is a single 4×4 dish. Hybrid colonies appear where either parent culture was active. Empty where both were sterile." So we need to combine two cultures: upper culture (cold-pigment colonies) and lower culture (warm-pigment colonies). The input grid is 9x4. The first 4 rows maybe represent the upper culture? Wait, the input has 9 rows. The description says "two-chambered petri dish divided by a golden membrane." So maybe the input grid is 9 rows: the top 4 rows are the upper culture, the bottom 4 rows are the lower culture, and the middle row is the membrane? But we have 9 rows: 4 + 1 + 4 = 9. Yes, that fits: 4 rows of upper culture, 1 row of membrane (maybe golden?), 4 rows of lower culture. But the input lines: 1-4: B B . . ; B . B . ; B B . B ; B B B B. That's 4 rows. Then row 5: Y Y Y Y. That might be the membrane? But Y Y Y Y is all Y's. But the description says "golden membrane" maybe Y stands for yellow? Yes Y=yellow. So the membrane row is Y Y Y Y. Then rows 6-9: R R . R ; . . R . ; . R . . ; R . R . . Wait, row 9 has 5 entries? Let's check again: The input lines after Y Y Y Y: "R R . R" (4 entries), ". . R ." (4 entries), ". R . ." (4 entries), "R . R ." (4 entries). So 4 rows of lower culture. So the input is 4 rows upper, 1 row membrane, 4 rows lower. So the output is 4x4 grid. The rule: "Any site where at least one chamber harbored a living colony blooms into a hybrid organism of a novel hue. Sterile sites remain barren." So we need to combine the upper and lower cultures: For each column and row index, we need to check if either the upper or lower cell is non-empty (i.e., not '.'), then output a new color (hybrid). The new color is a novel hue. In the example, the output uses G (green). So the hybrid color is G. So the rule: For each cell in the 4x4 output, if either the upper cell (in the upper 4x4 block) or the lower cell (in the lower 4x4 block) is not '.' (i.e., has a color), then output G. If both are '.' then output '.'.

But we need to confirm that the output matches the example. Let's test: For each position (i,j) where i=0..3, j=0..3. Upper cell: from rows 0-3. Lower cell: from rows 5-8 (since row 4 is membrane). Let's compute manually.

Upper grid (rows 0-3):
Row0: B B . .
Row1: B . B .
Row2: B B . B
Row3: B B B B

Lower grid (rows 5-8):
Row5: R R . R
Row6: . . R .
Row7: . R . .
Row8: R . R .

Now compute output: For each cell, if either upper or lower is not '.', output G else '.'.

Let's compute:

Row0:
- col0: upper B, lower R => G
- col1: upper B, lower R => G
- col2: upper ., lower . => '.'? Wait lower row5 col2 is '.'? Row5: R R . R => col2 '.' yes. So both '.' => '.'.
- col3: upper ., lower R => G

So row0: G G . G. That matches output row0: G G . G.

Row1:
- col0: upper B, lower . => G
- col1: upper ., lower . => '.'? Wait lower row6 col1 is '.'? Row6: . . R . => col1 '.' yes. So '.'.
- col2: upper B, lower R => G
- col3: upper ., lower . => '.'? Wait lower row6 col3 is '.'? Row6: . . R . => col3 '.' yes. So '.'.

So row1: G . G . That matches output row1: G . G .

Row2:
- col0: upper B, lower . => G
- col1: upper B, lower R => G
- col2: upper ., lower R => G
- col3: upper B, lower . => G

So row2: G G G G? Wait output row2: G G . G. Let's check: The output row2 is "G G . G". Wait the example output row2: "G G . G". Let's re-check the example output: Provided:

```
G G . G
G . G .
G G . G
G G G G
```

So row2 is "G G . G". But our calculation gave "G G G G". Let's double-check the lower grid row for row2: For row2 (i=2), lower row index is

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A starfield bisected by a golden band. Above: patches of cool nebular gas. Below: patches of hot nebular gas. The rest is void. What to do: Collapse both nebulae through the band. Any region containing gas from either nebula ignites into a newborn star. Void remains only where both sides were empty."

We have a 4x4 star chart with newborn stars where either nebula contributed matter.

We have training examples. Example 1: Input grid is 10x? Wait, let's parse.

Example 1 Input:
```
B B . .
B . B .
B B . B
B B B B
Y Y Y Y
R R . R
. . R .
. R . .
R . R .
```
Output:
```
G G . G
G . G .
G G . G
G G G G
```

So input grid is 10 rows? Let's count: lines: 1: B B . . ; 2: B . B . ; 3: B B . B ; 4: B B B B ; 5: Y Y Y Y ; 6: R R . R ; 7: . . R . ; 8: . R . . ; 9: R . R . . Wait line 9: "R . R ." ; 10: ??? Actually the input shows 9 lines? Let's recount: Provided input lines:

1. B B . .
2. B . B .
3. B B . B
4. B B B B
5. Y Y Y Y
6. R R . R
7. . . R .
8. . R . .
9. R . R .

That's 9 lines. But output is 4x4 grid. So maybe the input is 9x4? Wait each line has 4 columns. So input is 9 rows x 4 columns. Output is 4 rows x 4 columns. So transformation reduces rows from 9 to 4. The description: "A 4×4 star chart with newborn stars where either nebula contributed matter." So output is 4x4. Input is 9x4. So we need to map 9x4 to 4x4. The transformation rule: "Collapse both nebulae through the band. Any region containing gas from either nebula ignites into a newborn star. Void remains only where both sides were empty." So we have a band dividing the grid horizontally? The input has 9 rows. The band might be at row 5? Because we have 4 rows above (rows 1-4) and 4 rows below (rows 6-9). Row 5 is the band? Let's check: Row 5 is "Y Y Y Y". That might be the golden band. So the band is row 5. The rows above (1-4) are "cool nebular gas" (blue?). The rows below (6-9) are "hot nebular gas" (red?). The rest is void. The input uses B for blue, R for red, Y for golden band, . for void. So the rule: For each column, we collapse the two nebulae through the band: we look at each column, we consider the cells above the band (rows 1-4) and below the band (rows 6-9). For each column, if either side has a gas cell (B or R) in that column, then the output cell is a star (green). If both sides are empty (.), then output is empty. The output grid is 4x4. But we need to map 9 rows to 4 rows. How to map? The output grid is 4x4. The input has 4 rows above band and 4 rows below band. So maybe we collapse each column into a single cell? But output is 4x4, not 4x1. Wait, we need to produce 4x4 grid. So maybe we collapse each column into a 4x4 grid by mapping each of the 4 rows above to 4 rows in output? Let's analyze.

Input: 9 rows x 4 columns. Output: 4 rows x 4 columns. So we collapsed 9 rows into 4 rows. The band row (row 5) is removed. The 4 rows above and 4 rows below are collapsed into 4 rows. How? Maybe we collapse each column pair of rows (above and below) into a single row? But we need 4 rows output. Let's examine the mapping.

We have 4 rows above: rows 1-4. 4 rows below: rows 6-9. So we can pair row 1 with row 6, row 2 with row 7, row 3 with row 8, row 4 with row 9. That would produce 4 rows output. For each pair, we look at each column: if either cell in the pair is gas (B or R), output G; else . . That seems plausible. Let's test with example 1.

Input rows:

Row1: B B . .
Row2: B . B .
Row3: B B . B
Row4: B B B B
Row5: Y Y Y Y (band)
Row6: R R . R
Row7: . . R .
Row8: . R . .
Row9: R . R .

Now pair them:

Pair1: Row1 & Row6
- Column1: Row1 B, Row6 R => gas present => G
- Column2: Row1 B, Row6 R => G
- Column3: Row1 ., Row6 . => no gas => .
- Column4: Row1 ., Row6 R => G

So output row1: G G . G. That matches output row1: G G . G. Good.

Pair2: Row2 & Row7
- Col1: Row2 B, Row7 . => G
- Col2: Row2 . , Row7 . => . (both empty)
- Col3: Row2 B, Row7 R => G
- Col4: Row2 . , Row7 . => . (both empty)
Output row2: G . G . . Wait output row2: G . G . . But output row2 in example is "G . G .". Wait output row2: "G . G .". Yes, matches.

Pair3: Row3 & Row8
- Col1: Row3 B, Row8 . => G
- Col2: Row3 B, Row8 R => G
- Col3: Row3 ., Row8 . => .
- Col4: Row3 B, Row8 . => G
Output row3: G G . G. That matches output row3: G G . G.

Pair4: Row4 & Row9
- Col1: Row4 B, Row9 R => G
- Col2: Row4 B, Row9 . => G
- Col3: Row4 B, Row9 R => G
- Col4: Row4 B, Row9 . => G
Output row4: G G G G. That matches output row4: G G G G.

So the rule is: For each column, pair the row above the band with the corresponding row below the band (i.e., row i above with row i+4 below). For each pair, if either cell is gas (B or R), output G; else . . The band row is removed. The output grid is 4x4.

Now we need to apply this rule to the test input.

Test Input:

B . B .
B . B .

We need to parse the puzzle. We have a grid transformation puzzle. The description: "You are given a metaphorical description of the transformation, training examples, and a test input grid." The color key: .=black B=blue R=red G=green Y=yellow X=grey M=magenta O=orange A=azure W=maroon.

The metaphor: "What you see: A harbor chart split by a golden sandbar. Above: one fleet's anchorages marked in cool tones. Below: another fleet's in warm tones. Empty berths are open water. What to do: Erase the sandbar and merge the harbor. Any berth occupied by either fleet now flies a combined ensign. Only berths empty in both charts remain open water. Grid details: A 4×4 harbor with unified ensigns where either fleet had a ship."

So we have a 4x4 grid? Wait the training examples show bigger grids. Let's examine.

Example 1 Input: 
```
B B . .
B . B .
B B . B
B B B B
Y Y Y Y
R R . R

This is 9 rows? Let's count: lines: 1: B B . . ; 2: B . B . ; 3: B B . B ; 4: B B B B ; 5: Y Y Y Y ; 6: R R . R ; 7: . . R . ; 8: . R . . ; 9: R . R . . Wait line 9: R . R .? Actually the input shows "R . R ." but the line shows "R . R ."? Let's re-check: The input lines:

3. B B . B
4. B B B B
5. Y Y Y Y
6. R R . R
7. . . R .
8. . R . .
9. R . R .

But the last line "R . R ." has 4 cells: R, ., R, . . So 9 rows of 4 columns each. So the grid is 9x4? But the description says "A 4×4 harbor". But maybe the grid is 9x4? Let's examine Example 2 Input:

Again 9 rows of 4 columns. Example 3 Input:

Again 9 rows of 4 columns. So the grid is 9x4. But the description says "A 4×4 harbor with unified ensigns where either fleet had a ship." Maybe the 4x4 refers to the subgrid of interest? Let's analyze.

The input seems to consist of two 4x4 subgrids stacked vertically? Actually 9 rows: maybe the first 4 rows are the "cool tones" (blue) above the sandbar, the next row is the sandbar (golden?), then the next 4 rows are the warm tones (red) below the sandbar. But we have 9 rows: 4 rows of blue, 1 row of sandbar, 4 rows of red. But the input shows 9 rows: first 4 rows are B's and .; row 5 is Y Y Y Y; row 6-9 are R's and .; So row 5 is Y Y Y Y. That might be the sandbar? But Y is yellow, which is a warm tone? But the description says "golden sandbar" maybe Y stands for yellow. So Y Y Y Y is the sandbar row. So the grid is 9 rows: 4 rows of blue (cool tones), 1 row of sandbar (Y), 4 rows of red (warm tones). So the grid is 9x4. The transformation: "Erase the sandbar and merge the harbor. Any berth occupied by either fleet now flies a combined ensign. Only berths empty in both charts remain open water." So we need to combine the two 4x4 subgrids (blue and red) into a single 4x4 grid, where each cell is green if either of the two subgrids had a ship (B or R) in that position. If both are empty (.), then remains empty. So basically we overlay the two 4x4 grids: if either has a ship, output G; else output . . That seems to match the examples.

Let's test with Example 1: Input: first 4 rows (blue) are:

Row1: B B . .
Row2: B . B .
Row3: B B . B
Row4: B B B B

Row5: Y Y Y Y (sandbar)

Rows 6-9 (red) are:

Row6: R R . R
Row7: . . R .
Row8: . R . .
Row9: R . R .

Now we overlay: For each of the 4x4 positions (rows 1-4, columns 1-4), we check if either the blue grid or the red grid has a ship. But note that the red grid is rows 6-9, but we need to align them with the blue grid: row6 corresponds to row1 of the combined grid? Actually we overlay them: row6 (first row of red) corresponds to row1 of combined grid? Wait the red grid is 4 rows: rows 6-9. So we need to map them to the same 4x4 positions as the blue grid. So row6 -> row1, row7 -> row2, row8 -> row3, row9 -> row4. So we overlay row1 of blue with row1 of red, etc.

Let's overlay:

Row1: Blue: B B . . ; Red: R R . R
Positions:
col1: B or R? B present -> G
col2: B or R? B present -> G
col3: . or .? -> .
col4: . or R? R present -> G

So row1 output: G G . G

Row2: Blue: B . B . ; Red: . . R .
col1: B -> G
col2: . or . -> .
col3: B or R? B present -> G
col4: . or . -> .

So row2: G . G .

Row3: Blue: B B . B ; Red: . R . .
col1: B -> G
col2: B or R? B present -> G
col3: . or . -> .
col4: B or .? B present -> G

Row3: G G . G

Row4: Blue: B B B B ; Red: R . R .
col1: B or R? B present -> G
col2: B or .? B present -> G
col3: B or R? B present -> G
col4: B or .? B present -> G

Row4: G G G G

So output grid: 
Row1: G G . G
Row2: G . G .
Row3: G G . G
Row4: G G G G

Matches Example 1 output. Good.

## Metaphorical Description

What you see: A two-layer PCB split by a golden bus trace. The upper layer has active traces in some cells; the lower layer has active traces in others. Dead cells carry no current.
What to do: Laminate the layers through the bus. Any cell where either layer carried current lights a unified indicator. Cells dead on both layers stay off.
Grid details: A 4×4 output board with lit indicators wherever either layer was active.

Before predicting the output, perform a Conceptual Digestion:
1. Identify the CAST: What roles do different grid elements play?
2. Identify the AFFORDANCES: What can each element do or have done to it?
3. Identify the TRANSFORMATION RULE: What is the precise rule that maps input to output?

Then apply the rule to the test input to predict the output grid.

We need to produce output grid.

We need to understand the transformation rule. The description: "two-layer PCB split by a golden bus trace. The upper layer has active traces in some cells; the lower layer has active traces in others. Dead cells carry no current. Laminate the layers through the bus. Any cell where either layer carried current lights a unified indicator. Cells dead on both layers stay off. Grid details: A 4×4 output board with lit indicators wherever either layer was active."

So we have two layers: upper layer and lower layer. The input grid likely contains two layers of 4x4 each? But the input grid seems to be 9 rows? Let's examine.

Example 1 Input: 
```
B B . .
B . B .
B B . B
B B B B
Y Y Y Y
R R . R
. . R .
. R . .
R . R .
```
That's 9 rows. The first 4 rows maybe represent the upper layer? The next 4 rows maybe represent the lower layer? But there are 9 rows, not 8. Wait, maybe the first 4 rows are the upper layer, the next 4 rows are the lower layer, and the 9th row is something else? Let's examine the pattern.

Example 1 Input: 9 rows. Let's index them:

Row1: B B . .
Row2: B . B .
Row3: B B . B
Row4: B B B B
Row5: Y Y Y Y
Row6: R R . R
Row7: . . R .
Row8: . R . .
Row9: R . R .

Wait, there are 9 rows. But the description says "A 4×4 output board with lit indicators wherever either layer was active." So output is 4x4. So input must contain two 4x4 layers plus maybe a golden bus trace row? Let's examine the input: The first 4 rows are B's and .s. The next row is Y Y Y Y. That might be the golden bus trace row? Then the next 4 rows are R's and .s. That would be the lower layer. So the input grid is 4 rows of upper layer, 1 row of bus trace, 4 rows of lower layer. That totals 9 rows. Yes.

So the input grid is 9 rows: 4 rows of upper layer, 1 row of bus trace (maybe Y Y Y Y), 4 rows of lower layer. The bus trace row is Y Y Y Y. The Y's might represent the golden bus trace. The Y row is all Y's. So the bus trace is a row of Y's. The bus trace is maybe a row of Y's that splits the two layers. The transformation: "Laminate the layers through the bus. Any cell where either layer carried current lights a unified indicator. Cells dead on both layers stay off." So we need to combine the two layers: For each cell position (i,j) in the 4x4 grid, if either the upper layer cell or the lower layer cell is active (i.e., not '.'), then the output cell is lit (maybe G?). The output uses G for lit cells. The output grid uses G for lit cells and '.' for off cells. The output grid is 4x4. In the examples, the output grid uses G for lit cells and '.' for off cells. Yes.

Let's confirm with Example 1. Input: upper layer rows 1-4, lower layer rows 6-9. Let's write them:

Upper layer (rows 1-4):
Row1: B B . .
Row2: B . B .
Row3: B B . B
Row4: B B B B

Lower layer (rows 6-9):
Row6: R R . R
Row7: . . R .
Row8: . R . .
Row9: R . R .

Now we need to combine them: For each cell (i,j) where i=1..4, j=1..4, if either upper or lower cell is not '.' then output G else '.'.

Let's compute:

Row1: upper: B B . . ; lower: R R . R
- col1: upper B, lower R => G
- col2: upper B, lower R => G
- col3: upper ., lower . => .
- col4: upper ., lower R => G

So row1 output: G G . G. That matches Example 1 output row1: G G . G. Yes.

Row2: upper: B . B

We need to produce the output grid for the test input. The puzzle is a transformation puzzle. The training example shows an input grid and an output grid. We need to deduce the rule.

Let's parse the training example.

Input grid: It seems to be a 4x4 map? Wait the description says "A 4×4 map of life runes where either bank had a rune placed." But the input grid in Example 1 appears to be 10 rows? Let's examine.

Example 1 Input:

```
B B . .
B . B .
B B . B
B B B B
Y Y Y Y
R R . R
. . R .
. R . .
R . R .
```

That's 10 rows, each row has 4 columns? Let's check: Row 1: "B B . ." -> 4 columns. Row 2: "B . B ." -> 4 columns. Row 3: "B B . B" -> 4 columns. Row 4: "B B B B" -> 4 columns. Row 5: "Y Y Y Y" -> 4 columns. Row 6: "R R . R" -> 4 columns. Row 7: ". . R ." -> 4 columns. Row 8: ". R . ." -> 4 columns. Row 9: "R . R ." -> 4 columns. Wait row 9: "R . R ." -> 4 columns. Row 10: ??? Actually the input shows 9 rows? Let's count again: The input lines:

1. B B . .
2. B . B .
3. B B . B
4. B B B B
5. Y Y Y Y
6. R R . R
7. . . R .
8. . R . .
9. R . R .

That's 9 rows. But the output grid is 4 rows:

Output:
```
G G . G
G . G .
G G . G
G G G G
```

So the output is 4x4. The input is 9x4. So maybe the input is two separate 4x4 grids stacked vertically? Let's examine: The first 4 rows of input: rows 1-4: B B . .; B . B .; B B . B; B B B B. That's a 4x4 grid. Then row 5: Y Y Y Y. Row 6: R R . R. Row 7: . . R . . Row 8: . R . . Row 9: R . R . . Wait row 9: "R . R ." -> 4 columns. So rows 5-9: 5 rows? Actually row 5: Y Y Y Y; row 6: R R . R; row 7: . . R .; row 8: . R . .; row 9: R . R . . Wait row 9: "R . R ." -> 4 columns. So rows 5-9: 5 rows. But the output is 4x4. So maybe the input is two 4x4 grids separated by a row of Y Y Y Y? But Y Y Y Y is a row of 4 Y's. That might be a separator? Let's examine the test input: It is:

```
B . B .
B . B .
. B . .
B . B .
Y Y Y Y
R R . .
. . R .
. R . R
R R R .
```

That's 9 rows again. Let's count: 1: B . B .; 2: B . B .; 3: . B . .; 4: B . B .; 5: Y Y Y Y; 6: R R . .; 7: . . R .; 8: . R . R; 9: R R R . . Wait row 9: "R R R ." -> 4 columns. So 9 rows. So the input is 9 rows of 4 columns. The output is 4 rows of 4 columns. So the transformation is to produce a 4x4 output from a 9x4 input. The input seems to contain two 4x4 grids separated by a row of Y Y Y Y. The Y Y Y Y row might be a separator or a "river" of gold? The description: "A mythic river of gold divides two banks. One bank bears scattered frost runes; the other bears scattered fire runes. Some ground on each bank is bare." So the Y Y Y Y row might represent the river of gold. The two banks are the 4x4 grids above and below the Y Y Y Y row. The "frost runes" might be blue (B) and "fire runes" might be red (R). The "life rune" might be green (G). The "ground bare" might be black (.)? The "life rune" is green. The transformation: "Ford the river and unite the banks. Every position bearing a rune from either god transforms into a life rune. Only ground bare on both banks remains empty." So we need to combine the two banks into a single 4x4 grid. For each position (i,j) in the 4x4 grid, if either the top bank (row i in the top 4x4 grid) or the bottom bank (row i in the bottom 4x4 grid) has a rune (i.e., B or R), then

We need to parse the puzzle. The description: "A rehearsal floor split by a golden ribbon. Above: chalk marks from one company in cool tones. Below: marks from another in warm tones. Unmarked floor is bare. What to do: Remove the ribbon and combine choreographies. Any floor tile marked by either company is danced upon, leaving a unified mark. Only doubly-unmarked tiles stay clean. Grid details: A 4×4 floor showing unified dance marks wherever either company rehearsed."

So we have a 4x4 grid? But the training example input seems to be 8x? Let's examine.

Example 1 Input:

```
B B . .
B . B .
B B . B
B B B B
Y Y Y Y
R R . R

R . R .

Wait, that's 9 lines? Let's count: 1: B B . . ; 2: B . B . ; 3: B B . B ; 4: B B B B ; 5: Y Y Y Y ; 6: R R . R ; 7: . . R . ; 8: . R . . ; 9: R . R . . Wait, line 9: "R . R ." Actually the input shows 9 lines: 1-4 are B's and ., 5 is Y Y Y Y, 6 is R R . R, 7 is . . R ., 8 is . R . ., 9 is R . R . . Wait, the last line "R . R ." has 4 tokens? Actually "R . R ." is 4 tokens. So the input grid is 9 rows by 4 columns? Let's check each line: 
1: B B . . (4 tokens)
2: B . B . (4)
3: B B . B (4)
4: B B B B (4)
5: Y Y Y Y (4)
6: R R . R (4)
7: . . R . (4)
8: . R . . (4)
9: R . R . (4)

So 9 rows, 4 columns. Output:

```
G G . G
G . G .
G G . G
G G G G
```

Wait, output has 4 rows? Actually output lines: 1: G G . G ; 2: G . G . ; 3: G G . G ; 4: G G G G. That's 4 rows, 4 columns. So output is 4x4. Input is 9x4. So maybe the input is two separate 4x4 grids stacked vertically with a separator row? Let's examine: The first 4 rows are B's and ., second 4 rows are Y Y Y Y, R R . R, . . R ., . R . .? Wait, no. Let's separate:

Rows 1-4: B B . . ; B . B . ; B B . B ; B B B B. That's a 4x4 grid of B and . (blue and black). 
Rows 5-8: Y Y Y Y ; R R . R ; . . R . ; . R . . . That's a 4x4 grid of Y, R, ., etc. 
Row 9: R . R . . Wait, row 9 is "R . R .". That's 4 tokens. So maybe the input is 5x4? Wait, we need to re-evaluate. The input lines might be mis-copied. Let's re-check the original text:

Example 1:
Input:
B B . .
B . B .
B B . B
B B B B
Y Y Y Y
R R . R
. . R .
. R . .
R . R .
Output:
G G . G
G . G .
G G . G
G G G G

Wait, the input has 9 lines. But the output has 4 lines. So maybe the input is 9x4 but the output is 4x4. That seems inconsistent. But maybe the input is actually 8x4? Let's count again: The input lines: 
1: B B . .
2: B . B .
3: B B . B
4: B B B B
5: Y Y Y Y
6: R R . R
7: . . R .
8: . R . .
9: R . R .

Wait, there are 9 lines. But maybe the last line "R . R ." is part of the output? But the output is separate. The input ends at "R . R .". The output is separate. So input is 9x4. Output is 4x4. So maybe the input is two 4x4 grids stacked with a separator row of Y Y Y Y? But Y Y Y Y is a row of Y's. That might be the "golden ribbon" dividing the two halves. The description: "A rehearsal floor split by a golden ribbon. Above: chalk marks from one company in cool tones. Below: marks from another in warm tones. Unmarked floor is bare." So the golden ribbon might be a row of Y's? But Y is yellow, which is a warm tone. But the description says "golden ribbon" maybe represented by Y? But Y is yellow. But the input has Y

We need to parse the puzzle. We have a grid transformation puzzle. The description: "What you see: A cross-section of earth split by a golden fault. Above: veins of cool mineral in some positions. Below: veins of hot mineral in others. The rest is barren rock. What to do: Apply tectonic pressure to fuse the layers across the fault. Any position containing ore from either deposit crystallizes into a new gem. Barren-on-both positions remain plain rock."

We have a 4x4 geological layer with gemstones wherever either deposit had a mineral vein.

We have training examples. Example 1: Input grid is 8x? Wait, the input shows 8 rows? Let's examine.

Example 1 Input:
```
B B . .
B . B .
B B . B
B B B B
Y Y Y Y
R R . R
. . R .
. R . .
R . R .
```
Wait, that's 9 rows? Let's count: 1: B B . . ; 2: B . B . ; 3: B B . B ; 4: B B B B ; 5: Y Y Y Y ; 6: R R . R ; 7: . . R . ; 8: . R . . ; 9: R . R . . Wait, the last row has 4 columns? Actually "R . R ." is 4 columns. So 9 rows of 4 columns each. So input grid is 9x4? But the description says 4x4 geological layer. But maybe the input is 9x4? Let's examine the output.

Output:
```
G G . G
G . G .
G G . G
G G G G
```
That's 4 rows of 4 columns. So output is 4x4. So the transformation reduces the grid from 9x4 to 4x4. So maybe the input is two layers stacked: top 4 rows (cool mineral deposit) and bottom 4 rows (hot mineral deposit) with a middle row of Y Y Y Y? Wait, the input has 9 rows: first 4 rows are B's and .; row 5 is Y Y Y Y; rows 6-9 are R's and .; So maybe the Y Y Y Y row is the "golden fault" dividing the two layers. So the top 4 rows are the "cool mineral deposit" (blue B). The bottom 4 rows are the "hot mineral deposit" (red R). The Y Y Y Y row is the fault line. The rule: "Apply tectonic pressure to fuse the layers across the fault. Any position containing ore from either deposit crystallizes into a new gem. Barren-on-both positions remain plain rock." So we need to combine the two layers: For each column, we look at the top layer (rows 1-4) and bottom layer (rows 6-9). For each position (i.e., each column index), if either top or bottom has a mineral (B or R), then the output cell is a gem (G). If both are barren (.), then output is barren (.). So we need to produce a 4x4 grid where each cell corresponds to a column index? Wait, we need to map 9x4 to 4x4. The output has 4 rows and 4 columns. So each output cell corresponds to a column index? But we have 4 columns in input. So each output cell corresponds to a column index? But we also need 4 rows. So maybe each output row corresponds to a column index? Wait, we need to think.

Let's analyze the example: Input top 4 rows: 
Row1: B B . .
Row2: B . B .
Row3: B B . B
Row4: B B B B

Bottom 4 rows:
Row6: R R . R
Row7: . . R .
Row8: . R . .
Row9: R . R .

We need to produce 4x4 output. Let's compute for each column index (1-4) and each row index (1-4). But we need to map 9x4 to 4x4. Maybe we need to overlay the top and bottom layers: For each column, we look at the top 4 rows and bottom 4 rows. But we need 4 rows in output. So maybe each output row corresponds to a column index? Wait, we need to think about the transformation: "Apply tectonic pressure to fuse the layers across the fault. Any position containing ore from either deposit crystallizes into a new gem. Barren-on-both positions remain plain rock." So we have two layers: top and bottom. They are stacked vertically. The fault is between them. The transformation fuses them across the fault: So we overlay the two layers: For each position (row, column) in the combined 8x4 grid (top 4 rows + bottom 4 rows), we produce a gem if either top or bottom has ore at that position. But the output is 4x4, not 8x4. So maybe we compress the vertical dimension: We combine each pair of rows (top row i and bottom row i) into one output row i. That would produce 4 rows. That seems plausible: For each column j, we look at top row i and bottom row i (i from 1 to 4). If either has ore, output G at (i,j). So we overlay row i of top and row i of bottom. That yields 4x4 output. Let's test with example.

Compute for each i=1..4, j=1..4:

Top row1: B B . .
Bottom row1 (row6): R R . R

So for each column:
col1: top B, bottom R => G
col2: top B, bottom R => G
col3: top ., bottom . => .
col4: top ., bottom R => G

So row1 output: G G . G. That matches output row1: G G . G. Good.

Row2: top row2: B . B .
Bottom row2 (row7): . . R .
col1: B, . => G
col2: ., . => .
col3: B, R => G
col4: ., . => .
So row2 output: G . G . matches output row2: G . G . Good.

Row3: top row3: B B . B
Bottom row3 (row8): . R . .
col1: B, . => G
col2: B, R => G
col3: ., . => .
col4: B, . => G
Row3 output: G G . G matches output row3: G G . G.

Row4: top row4: B B B B
Bottom row4 (row9): R . R .
col1: B, R => G
col2: B, . => G
col3: B, R => G
col4: B, . => G
Row4 output: G G G G matches output row4: G G G G.

So the rule is: For each i from 1 to 4, overlay top row i and b

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A score split into upper and lower staves by a shimmering bar line. The upper staff has cool notes scattered across four measures; the lower staff has warm notes in different positions. What to do: Merge the two staves into one. Wherever either staff carried a note, the combined score sounds a harmonized tone. Rests persist only where both staves were silent. Grid details: One 4×4 staff of harmonized tones and rests."

We have training examples. Let's parse them.

We have a grid of 8 rows? Wait, the input grid seems to be 8 rows of 4 columns each? Let's check Example 1 Input:

```
B B . .
B . B .
B B . B
B B B B
Y Y Y Y
R R . R
. . R .
. R . .
R . R .
```

Wait, that's 9 rows? Let's count: 1: B B . . ; 2: B . B . ; 3: B B . B ; 4: B B B B ; 5: Y Y Y Y ; 6: R R . R ; 7: . . R . ; 8: . R . . ; 9: R . R . . Wait, the last line "R . R ." is 4 columns? Actually "R . R ." is 4 columns. So there are 9 rows? Let's count again: The input lines:

1. B B . .
2. B . B .
3. B B . B
4. B B B B
5. Y Y Y Y
6. R R . R
7. . . R .
8. . R . .
9. R . R .

Yes, 9 rows. But the output grid is 4 rows of 4 columns: "G G . G" etc. So the input grid is 9 rows? Wait, maybe the input grid is 8 rows? Let's check Example 2 Input:

```
B B B .
. B . B
. . B B
B B . B
Y Y Y Y
. . . R
. . . R
R R R R
R R . R
```

Count rows: 1: B B B . ; 2: . B . B ; 3: . . B B ; 4: B B . B ; 5: Y Y Y Y ; 6: . . . R ; 7: . . . R ; 8: R R R R ; 9: R R . R. That's 9 rows again. So input grid is 9 rows of 4 columns each. Output grid is 4 rows of 4 columns. So the transformation merges two staves (upper and lower) into one 4x4 grid. The input has 9 rows: maybe the first 4 rows are the upper staff? The next row is a bar line? The next 4 rows are the lower staff? But we have 9 rows, not 9? Wait, 4 + 1 + 4 = 9. Yes, that matches: 4 rows for upper staff, 1 row for bar line, 4 rows for lower staff. The bar line row is "Y Y Y Y" in both examples. So the bar line is a row of Y's. So the input grid is 9 rows: first 4 rows: upper staff; row 5: bar line; rows 6-9: lower staff. The output grid is 4 rows: the merged staff.

Now we need to figure out the transformation rule: "Merge the two staves into one. Wherever either staff carried a note, the combined score sounds a harmonized tone. Rests persist only where both staves were silent." So we need to combine the two 4x4 grids (upper and lower) into a single 4x4 grid. For each cell (i,j), if either upper or lower has a note (i.e., not a rest), then the output cell is a harmonized tone. The color of the harmonized tone? In the examples, the output grid uses G (green). So maybe the harmonized tone is always green. The input uses B (blue) for cool notes, R (red) for warm notes. The bar line uses Y (yellow). The output uses G (green). So the rule: For each cell, if either upper or lower has a note (B or R), output G. If both are rests (i.e., '.'), output '.'.

But we need to confirm with examples. Let's test Example 1.

Example 1 Input:

Upper staff (rows 1-4):
Row1: B B . .
Row2: B . B .
Row3: B B . B
Row4: B B B B

Lower staff (rows 6-9):
Row6: R R . R
Row7: . . R .
Row8: . R . .
Row9: R . R .

We need to combine them. Let's align them: For each of the 4 rows, we need to combine the corresponding rows from upper and lower. But we need to align them properly: The lower staff rows correspond to the same positions as the upper staff rows? The bar line is row 5. So lower staff row 6 corresponds to upper staff row 1? Or row 6 corresponds to row 1? Wait, we need to check the mapping. The output grid is 4 rows. Let's compute the output for each row.

We need to check the output grid for Example 1:

Output:
Row1: G G . G
Row2: G . G .
Row3: G G . G
Row4: G G G G

Let's compute using the rule: For each cell, if either upper or lower has a note, output G. Let's test row1: Upper row1: B B . . ; Lower row1: row6: R R . R. Combine: For each column:

- Col1: Upper B, Lower R => note => G
- Col2: Upper B, Lower R => G
- Col3: Upper ., Lower . => both rests => .
- Col4: Upper ., Lower R => G

So row1 output: G G . G. That matches.

Row2: Upper row2: B . B . ; Lower row2: row7: . . R . ; Combine:

- Col1: B, . => G
- Col2: ., . => .
- Col3: B, R => G
- Col4: ., . => .

Output: G . G . matches.

Row3: Upper row3: B B . B ; Lower row3: row8: . R . . ; Combine:

- Col1: B, . => G
- Col2: B, R => G
- Col3: ., . => .
- Col4: B, . => G

Output: G G . G matches.

Row4: Upper row4: B B B B ; Lower row4: row9: R . R . ; Combine:

- Col1: B, R => G
- Col2: B, . => G
- Col3: B, R => G
- Col4: B, . => G

Output: G G G G matches.

So the rule is correct: For each cell, if either upper or lower has a note (B or R), output G; else output '.'.

Now Example 2: Let's test.

Example 2 Input:

Upper staff rows 1-4:
Row1: B B B .
Row2: . B . B
Row3: . . B B
Row4: B B . B

Lower staff rows 6-9:
Row6: . . . R

We need to parse the puzzle. The description: "Two blueprint transparencies pinned above and below a golden lamp strip. Each has walls and open spaces in a 4×4 layout. What to do: Stack the transparencies on the lightbox. Any cell where at least one blueprint drew a wall becomes a built structure in the final plan. Only mutually open cells stay as open floor."

So we have two 4x4 grids: one above, one below. The input seems to contain 8 rows? Let's examine training examples.

Example 1 Input:

```
B B . .
B . B .
B B . B
B B B B
Y Y Y Y
R R . R
. . R .
. R . .
R . R .
```

Wait that's 9 rows? Let's count: lines:

1: B B . .
2: B . B .
3: B B . B
4: B B B B
5: Y Y Y Y
6: R R . R
7: . . R .
8: . R . .
9: R . R .

That's 9 rows. But the description says 4x4 layout. Maybe the first 4 rows are the top blueprint, next 4 rows are the bottom blueprint? But we have 9 rows. Let's examine: maybe the first 4 rows are top blueprint, next 4 rows are bottom blueprint, and the 9th row is something else? Wait maybe the 9th row is the output? But no, the output is separate.

Let's examine Example 1 Output:

```
G G . G
G . G .
G G . G
G G G G
```

That's 4 rows of 4 columns. So output is 4x4.

So input must contain two 4x4 grids. But we have 9 rows. Let's examine the pattern: The first 4 rows: B B . . / B . B . / B B . B / B B B B. That's 4x4. Then next 4 rows: Y Y Y Y / R R . R / . . R . / . R . . . Wait that's 4 rows? Let's count: Y Y Y Y (row 5), R R . R (row 6), . . R . (row 7), . R . . (row 8). That's 4 rows. Then row 9: R . R . (row 9). That's 1 row. So maybe the 9th row is something else? But maybe the input is 4x4 top blueprint, 4x4 bottom blueprint, and then 1 row of something else? But the description says "Two blueprint transparencies pinned above and below a golden lamp strip." So maybe the golden lamp strip is a row of Y's? Wait Y Y Y Y appears as row 5. That might be the golden lamp strip. So the input might be: top blueprint (rows 1-4), golden lamp strip (row 5), bottom blueprint (rows 6-9). But bottom blueprint is 4 rows: rows 6-9. That matches: row 6: R R . R, row 7: . . R ., row 8: . R . ., row 9: R . R . . Wait row 9 has 4 columns: R . R .? Actually row 9: R . R . (4 columns). Yes.

So the input format: 4 rows top blueprint, 1 row golden lamp strip (all Y's?), 4 rows bottom blueprint. That yields 9 rows total. The golden lamp strip is a row of Y's (maybe all Y's). In Example 1, row 5 is Y Y Y Y. In Example 2, let's check.

Example 2 Input:

```
B B B .
. B . B
. . B B
B B . B
Y Y Y Y
. . . R
. . . R
R R R R
R R . R
```

Count rows: 1: B B B .; 2: . B . B; 3: . . B B; 4: B B . B; 5: Y Y Y Y; 6: . . . R; 7: . . . R; 8: R R R R; 9: R R . R. So again 9 rows: 4 top blueprint, 1 golden lamp strip, 4 bottom blueprint. Good.

So the input format is consistent: 4 rows top blueprint, 1 row golden lamp strip (all Y's), 4 rows bottom blueprint. The golden lamp strip is just a row of Y's, maybe used to separate the two blueprint layers. The transformation: "Stack the transparencies on the lightbox. Any cell where at least one blueprint drew a wall becomes a built structure in the final plan. Only mutually open cells stay as open floor." So we need to overlay the two 4x4 grids: top blueprint and bottom blueprint. For each cell, if either top or bottom has a wall (i.e., a non-dot cell), then output is a wall (maybe represented by G?). Wait the output uses G for green. In the examples, output uses G for walls. The input uses B and R for walls? Let's examine Example 1: top blueprint uses B for walls, bottom blueprint uses R for walls. The output uses G for walls. So the rule: output grid uses G for walls (maybe green). The open cells are '.' (black). So the transformation: overlay top and bottom blueprint: if either cell is a wall (i.e., not '.'), output G; else output '.'.

But we need to confirm that the output uses G for walls. In Example 1 output: G G . G / G . G . / G G . G / G G G G. Let's overlay the two input grids to see if that matches.

Let's overlay Example 1:

Top blueprint (rows 1-4):
Row1: B B . .
Row2: B . B .
Row3: B B . B
Row4: B B B B

Bottom blueprint (rows 6-9):
Row6: R R . R
Row7: . . R .
Row8: . R . .
Row9: R . R .

We overlay: For each cell, if either top or bottom has a wall (B or R), output G; else '.'.

Let's compute row by row:

Row1: top: B B . . ; bottom: R R . R? Wait bottom row1 corresponds to row6? Actually bottom blueprint row1 is row6: R R . R. So overlay row1: top B B . . ; bottom R R . R. So cells: col1: top B, bottom R => wall => G. col2: top B, bottom R => G. col3: top ., bottom . => '.'? Wait bottom row6 col3 is '.'? Row6: R R . R => col3 '.' yes. So '.' remains '.'? But output row1 col3 is '.'? Output row1: G G . G. Yes col3 '.' matches. col4: top ., bottom R => G. So row1: G G . G. Good.

Row2: top: B . B . ; bottom: row7: . . R . => col1: top B, bottom . => G. col2: top ., bottom . => '.'? But output row2 col2 is '.'? Output row2: G . G . => yes.

We need to solve a grid transformation puzzle. The description: "You are given a metaphorical description of the transformation, training examples, and a test input grid. Color key: .=black B=blue R=red G=green Y=yellow X=grey M=magenta O=orange A=azure W=maroon"

We have a "metaphorical description" that says: "What you see: Two tactical maps separated by a golden demarcation line. Each map marks positions with its signature flare color against dark terrain. What to do: Overlay both maps. Any position flagged by either corps is marked as confirmed on the unified map in a new indicator color. Unflagged-by-both positions remain dark. Grid details: One 4×4 consolidated map with confirmed markers where either corps reported activity."

So we have two maps: one with blue markers (B) and one with red markers (R). They are separated by a golden demarcation line. The output is a 4x4 grid with green markers (G) where either B or R is present. The rest remain black (.). So basically we overlay the two maps and mark G where either B or R is present. That seems to be the rule.

But we need to confirm with training examples.

Example 1:

Input:
```
B B . .
B . B .
B B . B
B B B B
Y Y Y Y
R R . R
. . R .
. R . .
R . R .
```

Output:
```
G G . G
G . G .
G G . G
G G G G
```

Let's parse the input. The input seems to be 9 rows? Actually let's count: The input lines:

1. B B . .
2. B . B .
3. B B . B
4. B B B B
5. Y Y Y Y
6. R R . R
7. . . R .
8. . R . .
9. R . R .

So 9 rows. The first 4 rows are the blue map? The next 4 rows are the red map? But there are 5 rows of Y Y Y Y? Wait, the description says "Two tactical maps separated by a golden demarcation line." The golden demarcation line might be the Y Y Y Y row. So the input is: first 4 rows: blue map. Then a row of Y Y Y Y: golden demarcation line. Then next 4 rows: red map. That would be 4+1+4 = 9 rows. Yes.

So the input is 9 rows: 4 rows of B, 1 row of Y, 4 rows of R. The output is 4 rows of G. So the output is the overlay of the B and R maps: for each cell, if either B or R is present, output G; else output . (black). That matches the description.

Let's test with Example 1: The B map is:

Row1: B B . .
Row2: B . B .
Row3: B B . B
Row4: B B B B

The R map is:

Row1: R R . R
Row2: . . R .
Row3: . R . .
Row4: R . R .

Now overlay: For each cell, if B or R present, output G. Let's compute:

Row1: B B . . vs R R . R
- col1: B present -> G
- col2: B present -> G
- col3: . vs . -> no -> .
- col4: . vs R -> G

So row1: G G . G. That matches output row1.

Row2: B . B . vs . . R .
- col1: B -> G
- col2: . vs . -> .
- col3: B -> G
- col4: . vs . -> .

So row2: G . G . matches output row2.

Row3: B B . B vs . R . .
- col1: B -> G
- col2: B -> G
- col3: . vs . -> .
- col4: B -> G

Row3: G G . G matches output row3.

Row4: B B B B vs R . R .
- col1: B -> G
- col2: B -> G
- col3: B -> G
- col4: B -> G

Row4: G G G G matches output row4.

So rule holds.

Example 2:

Input:
```
B B B .
. B . B
. . B B
B B . B
Y Y Y Y
. . . R
. . . R
R R R R
R R . R
```

Wait, let's parse: 4 rows of B, 1 row of Y, 4 rows of R. But the B map is 4 rows: row1: B B B ., row2: . B . B, row3: . . B B, row4: B B . B. Then Y Y Y Y. Then R map: row1: . . . R, row2: . . . R, row3: R R R R, row4: R R . R. That is 4 rows of R.

Output:
```
G G G G
. G . G
G G G G
G G . G
```

Let's overlay: B map vs R map.

Row1: B B B . vs . . . R
- col1: B -> G
- col2: B -> G
- col3: B -> G
- col4: . vs R -> G

Row1: G G G G matches output.

Row2: . B . B vs . . . R
- col1: . vs . -> .
- col2: B -> G
- col3: . vs . -> .
- col4: B vs R -> G

Row2: . G . G matches output.

Row3: . . B B vs R R R R
- col1: . vs R -> G
- col2: . vs R -> G
- col3: B vs R -> G
- col4: B vs R -> G

Row3: G G G G matches output.

Row4: B B . B vs R R . R
- col1: B vs R -> G
- col2: B vs R -> G
- col3: . vs . -> .
- col4: B vs R -> G

Row4: G G . G matches output.

So rule holds.

Thus the transformation is: overlay two 4x4 maps separated by a row of Y Y Y Y. The first 4 rows are B map, the last 4 rows are R map. Output a 4x4 grid where each cell is G if either B or R is present in that cell; else . (black). So basically OR operation.

Now we need to apply to test input:

Test Input:
```
B . B .
B . B .
. B . .
B . B .
Y Y Y Y
R R . .
. . R .
. R . R
R R R .
```

Let's parse: 4 rows of B, 1 row of Y, 4 rows of R.

B map rows:

Row1: B . B .
Row2: B . B .
Row3: . B . .
Row4: B . B .

R map rows:

Row1: R R . .
Row2: . . R .
Row3: . R . R
Row4: R R R .

We need to overlay them.

Let's create a 4x4 grid. We'll index rows 1-4, columns 1-4.

B map:

- Row1: col1 B, col2 ., col3 B, col4 .
- Row2: col1 B, col2 ., col3 B, col4 .
- Row3: col1 ., col2 B, col3 ., col4 .
- Row4: col1 B, col2 ., col3 B, col4 .

R map:

- Row1: col1 R, col2 R, col3 ., col4 .
- Row2: col1 ., col2 ., col3 R, col4 .
- Row3: col1 ., col2 R, col3 ., col4 R
- Row4: col1 R, col2 R, col3

We need to solve a grid transformation puzzle. The description: "What you see: A stage divided by a golden scrim. Above: cool-toned shadow puppets in various positions. Below: warm-toned shadow puppets in other positions. Dark where no puppet appears. What to do: Remove the scrim and merge the performances. Wherever either troupe cast a shadow, a unified spotlight illuminates that spot in a new color. Only doubly-dark areas stay unlit."

We have a 4x4 stage with spotlit positions wherever either troupe performed. The training example shows input and output. We need to deduce the rule.

We have a grid transformation puzzle. The input grid is 8x4? Wait, the example input shows 8 rows? Let's examine Example 1:

Input:
B B . .
B . B .
B B . B
B B B B
Y Y Y Y
R R . R
. . R .
. R . .

R . R .

Wait, the input seems to have 9 rows? Let's count: The lines:

1: B B . .
2: B . B .
3: B B . B
4: B B B B
5: Y Y Y Y
6: R R . R
7: . . R .
8: . R . .
9: R . R .

So 9 rows. But the output shows 4 rows:

Output:
G G . G
G . G .
G G . G
G G G G

So output is 4 rows of 4 columns. So the input is 9 rows of 4 columns. The output is 4 rows of 4 columns. So the transformation reduces the grid from 9x4 to 4x4. The description: "A 4×4 stage with spotlit positions wherever either troupe performed." So the output is 4x4. The input seems to be 9x4. The top 4 rows might be the "cool-toned shadow puppets" (blue?), the bottom 4 rows might be the "warm-toned shadow puppets" (yellow? red?). The 5th row might be the golden scrim dividing them? Wait, the 5th row is Y Y Y Y. That might be the scrim? But Y is yellow. But the description says "golden scrim". But Y is yellow. So maybe Y row is the scrim. The top 4 rows are B (blue) and . (black). The bottom 4 rows are R (red) and . (black). The 5th row is Y Y Y Y. So the input is 9 rows: 4 rows of blue, 1 row of Y, 4 rows of red. The output is 4x4 grid of G (green). So the rule: combine the two 4x4 grids (top and bottom) by merging them: wherever either has a non-black cell, output a new color (green). But the output shows G in all positions where either top or bottom had a B or R. But we need to check if any positions had both B and R? The rule says "Only doubly-dark areas stay unlit." That means if both top and bottom had a black (.) at that position, then output remains black. But if either had a non-black, output is a new color. The new color is "unified spotlight illuminates that spot in a new color." In the example, the new color is G (green). So the rule: For each column and row index (0-3), if either the top 4x4 grid (rows 0-3) or the bottom 4x4 grid (rows 5-8) has a non-'.' cell, then output G at that position; else output '.'.

But we need to confirm with the example. Let's map the input:

Rows 0-3: top 4 rows (cool-toned). They are:

Row0: B B . .
Row1: B . B .
Row2: B B . B
Row3: B B B B

Rows 5-8: bottom 4 rows (warm-toned). They are:

Row5: R R . R
Row6: . . R .
Row7: . R . .
Row8: R . R .

Wait, row5 is R R . R. Row6: . . R . Row7: . R . . Row8: R . R . So bottom 4 rows.

Now we need to combine them. Let's create a 4x4 grid of booleans: top has B at positions: (0,0),(0,1),(1,0),(1,2),(2,0),(2,1),(2,3),(3,0),(3,1),(3,2),(3,3). bottom has R at positions: (0,0),(0,1),(0,3),(1,2),(2,1),(3,0),(3,2). Wait, bottom row indices relative to bottom 4 rows: row5 is index 0, row6 index 1, row7 index 2, row8 index 3. So bottom positions: (0,0),(0,1),(0,3),(1,2),(2,1),(3,0),(3,2). So combine: any position that has either B or R should be G. Let's check each of the 16 positions:

(0,0): top B, bottom R => G
(0,1): top B, bottom R => G
(0,2): top ., bottom . => .
(0,3): top ., bottom R => G
(1,0): top B, bottom . => G
(1,1): top ., bottom . => .
(1,2): top B, bottom R => G
(1,3): top ., bottom . => .
(2,0): top B, bottom . => G
(2,1): top B, bottom R => G
(2,2): top ., bottom . => .
(2,3): top B, bottom . => G
(3,0): top B, bottom R => G
(3,1): top B, bottom . => G
(3,2): top B, bottom R => G
(3,3): top B, bottom . => G

So the resulting grid should be:

Row0: G G . G
Row1: G . G .
Row2: G G . G
Row3: G G G G

Which matches the output. So the rule is correct.

Now we need to apply the rule to the test input.

Test Input:
B . B .
B . B .
. B . .
B . B .
Y Y Y Y
R R . .
. . R .
. R . R
R R R .

Wait, let's parse the test input. It has 9 rows of 4 columns each. Let's list them:

Row0: B . B .
Row1: B . B .
Row2: . B . .
Row3: B . B .
Row4: Y Y Y Y
Row5: R R . .
Row6: . . R .
Row7: . R . R
Row8: R R R .

So top 4 rows: rows 0-3. Bottom 4 rows: rows 5-8. Row4 is Y Y Y Y (scrim). So we need to combine top and bottom.

We need to produce a 4x4 output grid. The new color is G? In the example, the new color is G. But is that always G? The description says "unified spotlight illuminates that spot in a new color." The new color might be G. But we need to confirm if the new color is always G or depends on something else. The training example had only one ex

We need to solve a grid transformation puzzle. The description: "You are given a metaphorical description of the transformation, training examples, and a test input grid. Color key: .=black B=blue R=red G=green Y=yellow X=grey M=magenta O=orange A=azure W=maroon

Wait, the input has 10 rows. The first 4 rows are B and .? Actually first 4 rows: "B B . .", "B . B .", "B B . B", "B B B B". That's a 4x4 grid of B and .? Then next 4 rows: "Y Y Y Y", "R R . R", ". . R .", ". R . .", "R . R ."? Wait, let's parse carefully.

The input lines:

1. B B . .
2. B . B .
3. B B . B
4. B B B B
5. Y Y Y Y
6. R R . R
7. . . R .
8. . R . .
9. R . R .

Wait, that's 9 lines. But the output has 4 lines. So maybe the input is 9 lines? Let's count again: The input block shows 9 lines. But the output block shows 4 lines. So maybe the input is 9 rows, but the transformation uses only the first 4 rows? Or maybe the input is 9 rows but the transformation uses the first 4 rows as one bed, the next 4 rows as the second bed? But there are 9 rows, not 8. Let's examine Example 2.

Example 2 Input:
```
B B B .
. B . B
. . B B
B B . B
Y Y Y Y
. . . R
. . . R
R R R R
R R . R
```
Output:
```
G G G G
. G . G
G G G G
G G . G
```

Input lines: 9 lines again. Let's count: 1: B B B ., 2: . B . B, 3: . . B B, 4: B B . B, 5: Y Y Y Y, 6: . . . R, 7: . . . R, 8: R R R R, 9: R R . R. So 9 lines. Output has 4 lines. So maybe the input is 9 rows: first 4 rows are one bed, next 4 rows are second bed, and the 9th row is something else? But the description says "Two planting beds flanking a golden marigold border." The golden marigold border might be the Y row? Actually Y Y Y Y appears as a row of Y's. That might be the border between the two beds. So the input might be 9 rows: first 4 rows are left bed, row 5 is border (Y Y Y Y), next 4 rows are right bed. That would be 4+1+4 = 9 rows. Yes. So the input is a 9x4 grid: 9 rows, 4 columns. The first 4 rows are left bed, row 5 is border of Y's, rows 6-9 are right bed. The output is a 4x4 grid: the consolidated bed. So the transformation: For each cell in the 4x4 grid, if either left bed or right bed had a seedling (i.e., B or R?), then the output cell is G (hybrid). If both are empty (.), then output is . (empty). The Y row is just a border and not used in output. The left bed uses B cells? The right bed uses R cells? But the left bed might have B or R? Let's examine Example 1 left bed: rows 1-4: B B . ., B . B ., B B . B, B B B B. So left bed has B's and .s. Right bed: rows 6-9: R R . R, . . R ., . R . ., R . R .? Wait, let's parse rows 6-9: row 6: R R . R, row 7: . . R ., row 8: . R . ., row 9: R . R .? Actually row 9: R . R .? Wait, the input line 9 is "R . R ."? Let's check: In Example 1, the last line is "R . R ."? Wait, the input block shows:

```
B B . .
B . B .
B B . B
B B B B
Y Y Y Y
R R . R
. . R .
. R . .
R . R .
```

Yes, row 9 is "R . R .". So right bed rows 6-9: row 6: R R . R, row 7: . . R ., row 8: . R . ., row 9: R . R . . Wait, row 9 has 4 columns: R, ., R, .? Actually "R . R ." is 4 columns: R, ., R, . So yes.

Now, the output for Example 1 is:

```
G G . G
G . G .
G G . G
G G G G
```

Let's check if that matches the rule: For each cell (i,j) in 4x4, if left bed has B or right bed has R, output G. If both are ., output . . Let's test.

Left bed matrix (rows 1-4, columns 1-4):

Row1: B B . .
Row2: B . B .
Row3: B B . B
Row4: B B B B

Right bed matrix (rows 6-9):

Row6: R R . R
Row7: . . R .
Row8: . R . .
Row9: R . R .

Now compute output:

Row1: left: B B . ., right: R R . R. For each column:
col1: left B, right R => G
col2: left B, right R => G
col3: left ., right . => .
col4: left ., right R => G
So row1: G G . G. Matches output row1.

Row2: left: B . B ., right: . . R . => col1: B, . => G; col2: ., . => .; col3: B, R => G; col4: ., . => .? Wait, right row2 col4 is .? Right row2 is ". . R .", so col4 is . So left ., right . => . So row2: G . G .? But output row2 is "G . G ."? Wait, output row2 is "G . G ."? Let's check output: "G . G ."? Actually output row2 is "G . G ."? Wait, output row2: "G . G ."? Let's check the output block: "G . G ."? The output block shows:

```
G G . G
G . G .
G G . G
G G G G
```

So row2: G . G . Yes. So matches.

Row3: left: B B . B, right: . R . .? Wait,

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A dark night sky dotted with bright blue stars, each one alone in the void, quietly waiting to orient lost travelers. What to do: When dawn begins, each blue star awakens as a compass rose, projecting its cardinal beams into the surrounding darkness — a warm glow to the north, a sunset hue to the west, a violet flash to the east, and a cool shimmer to the south. The star itself remains blue at the center of its cross. Stars near the edge of the sky simply lose whichever beam would fly beyond the horizon. Grid details: The night sky is a square canvas of darkness. North is at the top, west is at the left. The sky does not grow or shrink when the stars ignite their beacons."

We have training example 1: Input grid 10x10 with '.' and 'B' only. Output grid 10x10 with many colors: O, B, M, R, A, etc. We need to deduce transformation rule.

We have to analyze the training example to figure out mapping from input to output. Then apply to test input.

Let's parse the training example.

Input grid (10x10). Let's index rows 0-9, columns 0-9. Input:

Row0: . . . . . B . . . .
Row1: . . . . . . . . . .
Row2: B . . . . . . . . .
Row3: . . . . . . . . . B
Row4: . . . . . . . . . .
Row5: . . . . . B . . . .
Row6: . . . . . . . . . .
Row7: . . . . . . . . . .
Row8: . . B . . . . . . .
Row9: . . . . . . . . . B

So there are B's at positions: (0,5), (2,0), (3,9), (5,5), (8,2), (9,9). That's 6 blue stars.

Output grid:

Row0: . . . . O B M . . .
Row1: R . . . . A . . . .
Row2: B M . . . . . . . R
Row3: A . . . . . . . O B
Row4: . . . . . R . . . A
Row5: . . . . O B M . . .
Row6: . . . . . A . . . .
Row7: . . R . . . . . . .
Row8: O B M . . . . . . R
Row9: . . A . . . . . O B

We need to interpret mapping. The description says: each blue star becomes a compass rose: a cross shape with beams in cardinal directions: north (up) warm glow, west (left) sunset hue, east (right) violet flash, south (down) cool shimmer. The star itself remains blue at center. The beams are colored accordingly: warm glow to north, sunset hue to west, violet flash to east, cool shimmer to south. Colors: warm glow maybe orange? Sunset hue maybe magenta? Violet flash maybe purple? Cool shimmer maybe blue? Wait star remains blue at center. But we need to map to color codes: O=orange, B=blue, M=magenta, R=red, A=azure, G=green, Y=yellow, X=grey, W=maroon. The description: "warm glow to the north" could be orange (O). "sunset hue to the west" could be magenta (M). "violet flash to the east" could be purple? But we don't have purple; maybe azure (A) or something. "cool shimmer to the south" could be blue? But star remains blue at center. Wait we need to map each cardinal direction to a color. Let's examine output to deduce mapping.

Take star at (0,5). In input, B at (0,5). In output, at (0,5) we have B (blue). Good. The beams: north would be above (row -1) but out of bounds, so no north beam. West: left of (0,5) is (0,4). Output at (0,4) is O. So west beam is O? Wait west is left, but output shows O at (0,4). But description says west is sunset hue. But O is orange. So maybe O is west? Let's check other stars.

Star at (2,0). Input B at (2,0). Output at (2,0) is B. Good. West beam would be left of (2,0) out of bounds. East beam: (2,1). Output at (2,1) is M. So east beam is M? But description says east is violet flash. M is magenta. So maybe M is east. North beam: (1,0). Output at (1,0) is R. So north beam is R? But description says north is warm glow. R is red. So maybe R is north. South beam: (3,0). Output at (3,0) is A. So south beam is A? But description says south is cool shimmer. A is azure. So maybe azure is south. West beam: (2,-1) out of bounds. So we have mapping: north -> R, east -> M, south -> A, west -> O? Wait we saw west beam at (0,4) is O. So west -> O. But we need to confirm with other stars.

Star at (3,9). Input B at (3,9). Output at (3,9) is B. West beam: (3,8). Output at (3,8) is O. So west -> O again. East beam: (3,10) out of bounds. North beam: (2,9). Output at (2,9) is R. So north -> R. South beam: (4,9). Output at (4,9) is A. So south -> A. Good.

Star at (5,5). Input B at (5,5). Output at (5,5) is B. West beam: (5,4). Output at (5,4) is O. East beam: (5,6). Output at (5,6) is M. North beam: (4,5). Output at (4,5) is R. South beam: (6,5). Output at (6,5) is A. Good.

Star at (8,2). Input B at (8,2). Output at (8,2) is B. West beam: (8,1). Output at (8,1) is O. East beam: (8,3). Output at (8,3) is M. North beam: (7,2). Output at (7,2) is R. South beam: (9,2). Output at (9,2) is A. Good.

Star at (9,9). Input B at (9,9). Output at (9,9) is B. West beam: (9,8). Output at (9,8) is O. East beam: (9,10) out of bounds. North beam: (8,9). Output at (8,9) is R. South beam: (10,9) out of bounds. So mapping holds.

Thus mapping: For each blue star, we create a cross shape: center remains B. The four cardinal directions

We need to solve a grid transformation puzzle. We have a training example: Input grid 10x10 with some B's (blue). Output grid has many colors: O, B, M, R, A, etc. We need to deduce rule. The description: "What you see: A dark ballroom floor with blue dancers at various positions. What to do: Each dancer extends one uniquely colored ribbon into each cardinal neighbor tile." So each blue dancer extends a ribbon into each cardinal neighbor tile. The output shows colored tiles around each B. The colors are unique per dancer? The description says "one uniquely colored ribbon into each cardinal neighbor tile." So each blue dancer extends a ribbon into each of its four cardinal neighbors. The ribbon color is unique per dancer. So each B has a unique color assigned to it, and that color is used for all four neighbor tiles of that B. But the output shows multiple colors: O, B, M, R, A, etc. Wait B is also present in output. But B is the original color of the dancer. In output, B remains at original positions? Let's check example 1.

Input Example 1: Let's parse.

Input grid 10x10:

Row0: . . . . . B . . . .
Row1: . . . . . . . . . .
Row2: B . . . . . . . . .
Row3: . . . . . . . . . B
Row4: . . . . . . . . . .
Row5: . . . . . B . . . .
Row6: . . . . . . . . . .
Row7: . . . . . . . . . .
Row8: . . B . . . . . . .
Row9: . . . . . . . . . B

So B positions: (0,5), (2,0), (3,9), (5,5), (8,2), (9,9). That's 6 B's.

Output grid:

Row0: . . . . O B M . . .
Row1: R . . . . A . . . .
Row2: B M . . . . . . . R
Row3: A . . . . . . . O B
Row4: . . . . . R . . . A
Row5: . . . . O B M . . .
Row6: . . . . . A . . . .
Row7: . . R . . . . . . .
Row8: O B M . . . . . . R
Row9: . . A . . . . . O B

Let's analyze. The B's remain at same positions? Let's check: (0,5) B remains B. (2,0) B remains B. (3,9) B remains B. (5,5) B remains B. (8,2) B remains B. (9,9) B remains B. Yes, B's remain.

Now, around each B, there are colored tiles. For each B, the four cardinal neighbors (up, down, left, right) are colored with a unique color for that B. But we need to see if the colors are consistent across all B's. Let's examine each B.

B at (0,5). Its neighbors: up (row -1) out of bounds, down (1,5), left (0,4), right (0,6). In output, at (1,5) we see A? Wait row1 col5: row1: R . . . . A . . . . So col5 is A. At (0,4) row0 col4: O. At (0,6) row0 col6: M. So the neighbors of B at (0,5) are colored O, A, M. But we expected four neighbors, but top neighbor is out of bounds, so only three neighbors. So the three neighbors are colored O, A, M. Are they all the same color? No, they are different. So maybe each neighbor gets a different color? But the description says "Each dancer extends one uniquely colored ribbon into each cardinal neighbor tile." That could mean each neighbor tile gets a ribbon of a unique color per dancer, but maybe each neighbor gets a different color? But the phrase "one uniquely colored ribbon into each cardinal neighbor tile" could mean each neighbor tile gets a ribbon of a unique color, but maybe each neighbor tile gets a different color? But the example shows that for B at (0,5), the three neighbors are O, A, M. So they are all different. So each neighbor tile gets a unique color per dancer, but the colors are not the same across neighbors. But the description says "one uniquely colored ribbon into each cardinal neighbor tile." That could be interpreted as each neighbor tile gets a ribbon of a unique color, but the color is unique per dancer? Actually "one uniquely colored ribbon" could mean each dancer has a unique color for its ribbon, but each neighbor tile gets that same ribbon color. But the example shows different colors for each neighbor tile of the same B. So maybe each neighbor tile gets a unique color per dancer, but the colors are not the same across neighbors. But the phrase "one uniquely colored ribbon into each cardinal neighbor tile" could also mean each dancer extends a ribbon into each neighbor tile, and each ribbon is uniquely colored (i.e., each ribbon has a unique color). But if each ribbon is unique, then each neighbor tile gets a different color. That matches the example: each neighbor tile of a B has a different color. But then we need to determine the mapping of colors to neighbor positions. Let's analyze further.

For B at (0,5), neighbors: left (0,4) O, right (0,6) M, down (1,5) A. So the colors are O, M, A. For B at (2,0), neighbors: up (1,0) R, down (3,0) A, right (2,1) M. So colors: R, A, M. For B at (3,9), neighbors: up (2,9) R, down (4,9) A, left (3,8) O. Colors: R, A, O. For B at (5,5), neighbors: up (4,5) R, down (6,5) A, left (5,4) O, right (5,6) M. Colors: R, A, O, M. For B at (8,2), neighbors: up (7,2) R, down (9,2) A, left (8,1) O, right (8,3) M. Colors: R, A, O, M. For B at (9,9), neighbors: up (8,9) R, left (9,8) O, down out of bounds, right out of bounds. Colors: R, O.

So each B has neighbors colored with a set of colors: R, A, O, M. But the distribution of colors across neighbors seems

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A dark sky with blue storm eyes at scattered locations. What to do: Each storm eye radiates one unique colored weather event into each of its four cardinal neighbors. Grid details: 10x10 grid, black background. Row 0 is top, column 0 is left. Dimensions unchanged."

We have training example 1: Input grid and output grid. We need to deduce the transformation rule. Then apply to test input.

We need to parse the training example. Let's rewrite the input and output grids in a more readable format.

Input Example 1:

Row0: . . . . . B . . . .
Row1: . . . . . . . . . .
Row2: B . . . . . . . . .
Row3: . . . . . . . . . B
Row4: . . . . . . . . . .
Row5: . . . . . B . . . .
Row6: . . . . . . . . . .
Row7: . . . . . . . . . .
Row8: . . B . . . . . . .
Row9: . . . . . . . . . B

Output Example 1:

Row0: . . . . O B M . . .
Row1: R . . . . A . . . .
Row2: B M . . . . . . . R
Row3: A . . . . . . . O B
Row4: . . . . . R . . . A
Row5: . . . . O B M . . .
Row6: . . . . . A . . . .
Row7: . . R . . . . . . .
Row8: . O B M . . . . . R
Row9: . . A . . . . . O B

We need to interpret the transformation. The metaphor: "dark sky with blue storm eyes at scattered locations. Each storm eye radiates one unique colored weather event into each of its four cardinal neighbors." So the input has blue storm eyes (blue cells). They radiate one unique colored weather event into each of its four cardinal neighbors. So each blue cell will produce a colored event in each of its four neighbors. The output grid has many colors: O, B, M, R, A, etc. The input only had B cells. The output has B cells too, but also other colors. The output also has B cells at the same positions as input? Let's check: Input B positions: (0,5), (2,0), (3,9), (5,5), (8,2), (9,9). Output B positions: Let's list all B's in output: Row0 col5 B, row2 col0 B, row3 col9 B, row5 col5 B, row8 col2 B, row9 col9 B. Yes, the B's remain at same positions. So B cells are preserved. Additionally, new colored cells appear around them. Let's examine each B cell and its neighbors.

We need to identify the unique colored weather event for each storm eye. The metaphor says "radiates one unique colored weather event into each of its four cardinal neighbors." So each B cell will produce a unique color that is the same for all four neighbors? Or each neighbor gets a unique color? The phrase "one unique colored weather event into each of its four cardinal neighbors" could mean each B cell emits a single color that is unique to that B cell, and that color is placed in each of its four neighbors. So each B cell will produce the same color in all four neighbors. But the output shows that each B cell's neighbors have different colors? Let's check.

Take B at (0,5). Its neighbors: up (none), down (1,5), left (0,4), right (0,6). In output, at (1,5) we have B? Wait output row1 col5 is A? Let's check output row1: "R . . . . A . . . ." So row1 col5 is A. Row0 col4 is O. Row0 col6 is M. So the neighbors of B at (0,5) are (1,5)=A, (0,4)=O, (0,6)=M. So they are different colors: O, M, A. So each neighbor gets a different color. But the phrase "one unique colored weather event into each of its four cardinal neighbors" could mean each neighbor gets a unique color, but maybe each neighbor gets a different color from the B cell's unique color? But the output shows three different colors for the three neighbors. So maybe each B cell has a unique set of colors for its neighbors? Let's examine B at (2,0). Its neighbors: up (1,0), down (3,0), left (none), right (2,1). Output: row1 col0 is R. Row3 col0 is A. Row2 col1 is M. So again three different colors: R, A, M. B at (3,9). Neighbors: up (2,9), down (4,9), left (3,8), right (none). Output: row2 col9 is R. Row4 col9 is A. Row3 col8 is O. So again R, A, O. B at (5,5). Neighbors: up (4,5), down (6,5), left (5,4), right (5,6). Output: row4 col5 is R. Row6 col5 is A. Row5 col4 is O. Row5 col6 is M. So again R, A, O, M. B at (8,2). Neighbors: up (7,2), down (9,2), left (8,1), right (8,3). Output: row7 col2 is R. Row9 col2 is A. Row8 col1 is O. Row8 col3 is M. B at (9,9). Neighbors: up (8,9), down (none), left (9,8), right (none). Output: row8 col9 is R. Row9 col8 is O. So again R, O, A? Wait row9 col8 is O, row8 col9 is R. So two neighbors: R and O. So each B cell's neighbors are colored with a set of colors: R, A, O, M. But the order may vary. Let's check the pattern: For B at (0,5), neighbors: left O, right M, down A. For B at (2,0), neighbors: up R, down A, right M. For B at (3,9), neighbors: up R, left O, down A. For B at (5,5), neighbors: up R, down A, left O, right M. For B at (8,2), neighbors: up R, down A, left O, right M. For B at (9,9), neighbors: up R, left O. So the set of colors used for neighbors is always {R, A, O, M}. But the assignment of which neighbor gets which color seems to follow a pattern: maybe the colors are assigned based on direction: up ge

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A dark battlefield with blue command posts at scattered positions. What to do: Each command post sends one uniquely colored scout one step into each cardinal direction. Grid details: 10x10 grid, black background. Row 0 is top, column 0 is left. Dimensions unchanged."

We have training example 1: Input grid 10x10 with B's at certain positions. Output grid has many colors: O, B, M, R, A, etc. We need to deduce transformation rule.

We have test input: 10x10 grid with B's at certain positions. We need to produce output grid.

We need to analyze training example 1 to deduce rule.

Let's parse training example 1.

Input grid:

Row 0: . . . . . B . . . .
Row 1: . . . . . . . . . .
Row 2: B . . . . . . . . .
Row 3: . . . . . . . . . B
Row 4: . . . . . . . . . .
Row 5: . . . . . B . . . .
Row 6: . . . . . . . . . .
Row 7: . . . . . . . . . .
Row 8: . . B . . . . . . .
Row 9: . . . . . . . . . B

So B positions: (0,5), (2,0), (3,9), (5,5), (8,2), (9,9). 6 B's.

Output grid:

Row 0: . . . . O B M . . .
Row 1: R . . . . A . . . .
Row 2: B M . . . . . . . R
Row 3: A . . . . . . . O B
Row 4: . . . . . R . . . A
Row 5: . . . . O B M . . .
Row 6: . . . . . A . . . .
Row 7: . . R . . . . . . .
Row 8: . O B M . . . . . R
Row 9: . . A . . . . . O B

We need to interpret mapping.

We have B's in input. In output, B's remain at same positions? Let's check: Input B at (0,5). Output row 0 col 5: B. Yes. Input B at (2,0). Output row 2 col 0: B. Yes. Input B at (3,9). Output row 3 col 9: B. Yes. Input B at (5,5). Output row 5 col 5: B. Yes. Input B at (8,2). Output row 8 col 2: B. Yes. Input B at (9,9). Output row 9 col 9: B. Yes. So B's stay same.

Now other colors appear: O, M, R, A. They appear in positions adjacent to B's? Let's check.

For each B, we might have scouts moving one step in each cardinal direction. The metaphor says: "Each command post sends one uniquely colored scout one step into each cardinal direction." So each B sends a scout in each of four directions: up, down, left, right. Each scout has a unique color. So each B has four scouts, each with a unique color. The colors used: O, M, R, A. So each B's scouts are colored O, M, R, A. But we need to determine which color goes to which direction. The output shows O, M, R, A at positions adjacent to B's. Let's check.

Take B at (0,5). Adjacent positions: up: ( -1,5 ) out of bounds. Down: (1,5). Left: (0,4). Right: (0,6). Output at (1,5) is B? Wait output row 1 col 5: A? Let's check output row 1: "R . . . . A . . . ." So row 1 col 5 is A. So down from B at (0,5) is A. Left from B at (0,5) is (0,4). Output row 0 col 4: O. Right from B at (0,5) is (0,6). Output row 0 col 6: M. So for B at (0,5), we have scouts: left: O, down: A, right: M. Up is out of bounds. So we have O, A, M. But we also need R somewhere? Maybe R is for up? But up is out of bounds, so no R. So maybe each B's scouts are colored O, M, R, A in some order: maybe left: O, right: M, up: R, down: A. That matches B at (0,5). Let's test with other B's.

B at (2,0). Adjacent positions: up: (1,0). Down: (3,0). Left: (2,-1) out of bounds. Right: (2,1). Output at (1,0): R? Let's check output row 1 col 0: R. Yes. Down: (3,0) output row 3 col 0: A? Wait output row 3: "A . . . . . . . O B". So row 3 col 0: A. Right: (2,1) output row 2 col 1: M? Wait output row 2: "B M . . . . . . . R". So row 2 col 1: M. So left is out of bounds. So we have up: R, down: A, right: M. That matches the pattern: up: R, down: A, right: M. So far consistent.

B at (3,9). Adjacent positions: up: (2,9). Down: (4,9). Left: (3,8). Right: (3,10) out of bounds. Output at (2,9): R? Let's check output row 2 col 9: R. Yes. Down: (4,9) output row 4 col 9: A? Row 4: ". . . . . R . . . A". So col 9: A. Left: (3,8) output row 3 col 8: O? Row 3: "A . . . . . . . O B". So col 8: O. So up: R, down: A, left: O. Right out of bounds. So pattern holds: up: R, down: A, left: O, right: M. Good.

B at (5,5). Adjacent positions: up: (4,5). Down: (6,5). Left: (5,4). Right: (5,6). Output at (4,5): R? Row 4: ". . . . . R . . . A". So col 5: R. Down: (6,5) output row 6 col 5: A? Row 6: ". . . . . A . . . .". So col 5: A. Left: (5,4) output row 5 col 4: O? Row 5: ". . . . O B M . . .". So col 4: O. Right: (5,6) output row 5 col 6: M? Row 5 col 6: M. So pattern holds.

B at (8,2). Adjacent positions: up: (7,2). Down: (9,2). Left: (8,1). Right: (8,3). Output at (7,2): R? Row 7: ". . R . . . . . . .". So col 2: R. Down: (9,2) output row 9 col 2: A? Row 9: ". . A . . . . . O B". So col 2: A. Left: (8,1) output row 8 col 1: O? Row 8: ". O B M . . . . . R". So col 1: O. Right: (8,3) output row 8 col 3: M? Row 8 col 3: M. So pattern holds.

B at (9,9). Adjacent positions: up: (8,9). Down: (10,9) out of bounds. Left: (9,8). Right: (9,10) out of bounds. Output at (8,9): R? Row 8 col 9: R. Yes. Left: (9,8) output row 9 col 8: O? Row 9 col 8: O. So pattern holds: up: R, left: O. R

We need to parse the puzzle. The description: "glowing emerald hearth (the 2×2 green block) sits in the darkness, while lonely travelers of various colors are scattered across the land. Some travelers happen to stand on a road—a shared row or column—that leads straight to the hearth; others wander paths that never cross it. Each traveler who finds themselves on a road aligned with the hearth feels its warmth and leaves a trail of their own color behind them as they are pulled toward it—like footprints glowing in the snow. The trail stretches from where the traveler stands all the way to the hearth's doorstep, but the traveler never moves and the hearth is never disturbed. Those who share no road with the hearth remain where they are, unaware of its light."

So we have a 10x10 grid. There is a 2x2 green block somewhere. The "traveler" cells are colored single cells of various colors. The rule: For each traveler that shares a row or column with the green block (i.e., is in same row or same column as any of the green cells), we draw a line of that color from the traveler to the green block's "doorstep" (the nearest cell adjacent to the green block? Or the entire path to the green block?). The description: "leaves a trail of their own color behind them as they are pulled toward it—like footprints glowing in the snow. The trail stretches from where the traveler stands all the way to the hearth's doorstep, but the traveler never moves and the hearth is never disturbed." So we fill cells along the straight line between the traveler and the green block, but not including the green block itself? The "doorstep" might be the cell adjacent to the green block along that line? But the description says "the hearth's doorstep" maybe the cell adjacent to the green block along the line? But the traveler never moves, so the trail is from the traveler to the doorstep, not including the hearth. But the hearth remains unchanged. So we fill cells along the line from the traveler to the cell adjacent to the green block along that line. But if the traveler is in the same row or column as the green block, the line is horizontal or vertical. So we fill all cells between the traveler and the green block, excluding the green block cells. But we might also fill the cell adjacent to the green block? The "doorstep" might be the cell adjacent to the green block along that line. But if the traveler is in the same row or column, the line will end at the green block's edge. The "doorstep" might be the cell just before the green block. So we fill all cells from the traveler to the cell adjacent to the green block, inclusive of that adjacent cell. But we might also fill the green block cells? The description says "the hearth is never disturbed." So we do not modify the green block cells. So we fill only the cells between the traveler and the green block, not including the green block cells. But we might fill the cell adjacent to the green block. That cell might be part of the green block? Wait, the green block is 2x2. So the "doorstep" might be the cell adjacent to the green block along the line. But if the traveler is in the same row or column, the line will end at the green block's edge. The "doorstep" might be the cell adjacent to the green block along that line, which is the cell just before the green block. So we fill all cells from the traveler to that adjacent cell inclusive. That includes the cell adjacent to the green block. But we do not fill the green block cells. So the line stops just before the green block.

But we need to confirm with the training example.

Let's analyze Example 1.

Input grid (10x10). Let's label coordinates: row 0-9, col 0-9.

Input:

Row0: . O . . . . A . . .
Row1: . . . . . . . . . .
Row2: . . . O . G G . . A
Row3: . . . . . G G . . .
Row4: . . . . . . . . . .
Row5: . A . . . . . . . .
Row6: . . . . . . . . A .
Row7: . . . A . . . . . .
Row8: . O . . . . . . . .
Row9: . . . . . O . . . O

Output:

Row0: . O . . . . A . . .
Row1: . . . . . . A . . .
Row2: . . . O O G G A A A
Row3: . . . . . G G . . .
Row4: . . . . . O . . . .
Row5: . A . . . O . . . .
Row6: . . . . . O . . A .
Row7: . . . A . O . . . .
Row8: . O . . . O . . . .
Row9: . . . . . O . . . O

We need to see the green block location. In input, green cells at (2,5),(2,6),(3,5),(3,6). So 2x2 block at rows 2-3, cols 5-6. That matches the description: 2x2 green block.

Now we need to see the colored travelers: O, A, etc. Let's list all colored cells in input:

Row0: col1 O, col6 A
Row2: col3 O, col8 A
Row3: col5 G, col6 G (green block)
Row5: col1 A
Row6: col8 A
Row7: col3 A
Row8: col1 O
Row9: col5 O, col9 O

Also maybe other colors? There is no R, B, etc. So we have O and A travelers.

Now we need to see which travelers are in same row or column as the green block. The green block occupies rows 2-3, cols 5-6. So any traveler in row 2 or 3 or column 5 or 6 will be considered "aligned".

Let's check each traveler:

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A battlefield (5×5) is strewn with warriors of a single tribe — blue, red, or green — scattered among empty darkness. Their positions are chaotic, as if flung by a storm, but every warrior wears the same color, and that color is the name of their tribe. What to do: Ignore where the warriors fell — their arrangement is a feint. Instead, read the color of their armor to learn which tribe has taken the field. Each tribe carries an ancestral sigil, a compact grey emblem stamped onto a 3×3 seal. The blue tribe's sigil radiates outward from the center in four directions. The red tribe's sigil stands tall, crowned with a broad brim. The green tribe's sigil hunkers into one corner, bracing two walls that meet at the foundation. Summon the correct sigil and the battle resolves. Grid details: The battlefield is a 5×5 expanse of darkness dotted with a single tribe's colored warriors. The ancestral seal is a 3×3 tablet where the sigil is rendered in grey (X) against black emptiness — always five stones placed, four spaces left bare."

We have training examples: Example 1, 2, 3. Input grids are 5x5 with B, R, G, or . (black). Output grids are 3x3 with X and . (black). The output is a 3x3 pattern of X's and . that corresponds to the "sigil" of the tribe. The description says: "The blue tribe's sigil radiates outward from the center in four directions. The red tribe's sigil stands tall, crowned with a broad brim. The green tribe's sigil hunkers into one corner, bracing two walls that meet at the foundation." So each tribe has a unique 3x3 pattern of 5 X's (grey stones) and 4 . (black emptiness). The pattern is always 5 X's. The input grid is 5x5 with colored warriors of a single tribe. The arrangement is chaotic, but we need to ignore positions and just read the color to determine which tribe. Then output the corresponding 3x3 pattern.

Thus the transformation rule: Identify the color present in the input grid (B, R, or G). Then output the 3x3 pattern for that color. The pattern is predetermined: For blue: "radiates outward from the center in four directions." That likely means a cross shape: X at center, X at up, down, left, right. That would be 5 X's: center and four orthogonal neighbors. That pattern is a plus sign. For red: "stands tall, crowned with a broad brim." That might be a vertical line with a horizontal top? Or a shape like a T? "Tall" suggests vertical line of 3 X's, "crowned with a broad brim" suggests a horizontal line of 3 X's at the top? But we need exactly 5 X's. A T shape: top row all X's (3), middle row center X (1), bottom row center X (1) would be 5 X's. That is a T shape. For green: "hunkers into one corner, bracing two walls that meet at the foundation." That suggests a corner shape: X's at the corner and along two sides. For example, top-left corner: X at (0,0), X at (0,1), X at (1,0), X at (1,1), X at (0,2)? Wait, we need 5 X's. The shape might be a 2x2 block plus one extra X at the corner? Let's parse: "hunkers into one corner, bracing two walls that meet at the foundation." That suggests a shape that occupies a corner and extends along two walls (horizontal and vertical). So maybe a shape like a corner with a 2x2 block plus one X at the corner? But we need 5 X's. Let's think: The shape might be a 3x3 pattern where the X's form a corner shape: X at (0,0), X at (0,1), X at (0,2), X at (1,0), X at (2,0). That would be a corner shape with a horizontal line of 3 X's at top row and vertical line of 3 X's at left column, overlapping at (0,0). That would be 5 X's: top row 3, left column 3, minus one duplicate at (0,0) gives 5. That matches "hunkers into one corner, bracing two walls that meet at the foundation." So the green pattern is a corner shape: a 3x3 with X's at top row and left column. That is a corner shape.

Now let's verify with training examples.

Example 1 Input: 5x5 grid with B's. Output: 3x3 grid:
. X .
X X X
. X .

Let's check: The output pattern is:
Row0: . X .
Row1: X X X
Row2: . X .
This is a plus shape? Let's see: center at (1,1) is X. Up at (0,1) is X. Down at (2,1) is X. Left at (1,0) is X. Right at (1,2) is X. Yes, that's a plus shape. So for blue, the pattern is plus shape. That matches "radiates outward from the center in four directions." Good.

Example 2 Input: 5x5 grid with R's. Output:
X X X
. X .
. X .

Let's check: Row0: X X X
Row1: . X .
Row2: . X .
This is a T shape: top row all X's, center column X's at rows 1 and 2. That matches "stands tall, crowned with a broad brim." Yes, a T shape.

Example 3 Input: 5x5 grid with G's. Output:
. . X
. . X
X X X

Let's check: Row0: . . X
Row1: . . X
Row2: X X X
This is a corner shape but rotated? Let's see: The X's are at (0,2), (1,2), (2,0), (2,1), (2,2). That is a corner shape at bottom-left? Actually, the shape is a corner at bottom-left: bottom row all X's (3), right column all X's (3), o

We need to solve a grid transformation puzzle. We have training examples. We need to deduce the rule. Let's analyze.

We have input grids 5x5, output grids 3x3. The input contains one colored species scattered among empty medium. The output is a 3x3 protein structure in grey on black, determined solely by species identity. So the output depends only on the color of the species, not on the positions. The output is a 3x3 pattern of X (grey) and . (black). The pattern is unique per color. We have training examples for colors B, R, G, B again? Wait Example 1 uses B, Example 2 uses R, Example 3 uses G, Example 4 uses B again. So we have patterns for B, R, G. We need to produce output for G (since test input is G). But we need to confirm that the pattern for G is consistent across examples. Example 3 uses G and output is:

. . X
. . X
X X X

Let's confirm. Example 3 input: 5x5 grid with G's. Output: 3x3 grid:

Row1: . . X
Row2: . . X
Row3: X X X

Yes.

Now we need to produce output for G. But we need to confirm that the pattern for G is indeed that. But we also need to confirm that the pattern for B and R are consistent across examples. Example 1: B output:

. X .
X X X
. X .

Example 4: B output:

. X .
X X X
. X .

Yes same pattern. Good. Example 2: R output:

X X X
. X .
. X .

So pattern for R is:

Row1: X X X
Row2: . X .
Row3: . X .

Now we need to produce output for G. Pattern for G is:

Row1: . . X
Row2: . . X
Row3: X X X

Now we need to produce output grid for test input: 5x5 grid with G's. So output should be the G pattern.

But we need to double-check that the pattern for G is indeed that. Let's analyze the training examples to confirm.

Example 3 input:

. G . G .
G G . . .
. G . . .
. . G . .
G G G . .

Let's map coordinates. 5x5 grid. Let's index rows 0-4, columns 0-4.

Row0: . G . G . => positions (0,1) and (0,3) are G.
Row1: G G . . . => (1,0),(1,1)
Row2: . G . . . => (2,1)
Row3: . . G . . => (3,2)
Row4: G G G . . => (4,0),(4,1),(4,2)

So G's are scattered. Output pattern: 3x3 grid:

Row0: . . X
Row1: . . X
Row2: X X X

So pattern is like a right triangle oriented with right side vertical at column 2? Actually 3x3 grid: columns 0-2. Row0: col0 '.', col1 '.', col2 'X'. Row1: col0 '.', col1 '.', col2 'X'. Row2: col0 'X', col1 'X', col2 'X'.

So shape is like a 3x3 block with a vertical line on right side and a horizontal line at bottom. Equivalent to a 3x3 "L" shape rotated 90 degrees? Let's think: The shape is like a 3x3 block with missing top-left 2x2 area. So it's like a 3x3 block with a 2x2 missing at top-left. So shape is like a 3x3 block with a 2x2 missing at top-left. That shape is symmetrical to B pattern? Let's check B pattern: Example 1 and 4 output for B:

. X .
X X X
. X .

This shape is like a 3x3 block with a vertical line at center column 1, horizontal line at middle row 1, but missing corners? Actually B pattern: Row0: . X . (col0 '.', col1 'X', col2 '.'). Row1: X X X (col0 'X', col1 'X', col2 'X'). Row2: . X . (col0 '.', col1 'X', col2 '.').

So shape is like a cross shape? Actually it's like a vertical line at column 1, horizontal line at row 1, but corners are '.'.

R pattern: X X X
. X .
. X .

So shape is like a vertical line at column 1, horizontal line at row 0, but missing bottom row? Actually R pattern: Row0: X X X (full top row). Row1: . X . (vertical line at center). Row2: . X . (vertical line at center). So shape is like a vertical line at center plus top row.

G pattern: . . X
. . X
X X X

So shape is like a vertical line at rightmost column, horizontal line at bottom row.

So each color corresponds to a different orientation of a 3x3 shape: B is vertical line at center + horizontal line at middle row. R is vertical line at center + horizontal line at top row. G is vertical line at rightmost column + horizontal line at bottom row. So maybe each color corresponds to a direction: B maybe "north-south" orientation? R maybe "north"? G maybe "east"? But we need to deduce mapping.

But we only need to produce output for G. So we can just output the pattern for G.

But we need to confirm that the pattern for G is indeed that. Let's double-check Example 3 output: . . X / . . X / X X X. Yes.

Now we need to produce output grid for test input: 5x5 grid with G's. So output should be:

. . X
. . X
X X X

But we need to output using the color key: '.' for black, 'X' for grey. So we need to output 3 lines each with 3 characters separated by spaces? The instructions: "At the very end of your response, write the complete output grid inside a clearly labeled block like this: ANSWER: . B R G Y ."

But the example shows "ANSWER:" then grid lines with spaces between characters. So we need to produce:

ANSWER:
. . X
. . X
X X X

But we need to confirm that the output grid uses spaces between characters. The example shows:

ANSWER:
. B R
G Y .

But that example uses spaces between characters. So we should follow that.

Thus final answer:

ANSWER:
. . X
. . X
X X X

We need to solve a grid transformation puzzle. The description: "What you see: Stars of one spectral color scattered across a dark sky plate. What to do: Classify the spectral type by color and predict the stellar remnant — a small fixed shape that spectral class alone determines. Grid details: Input: 5x5 sky with one star color. Output: 3x3 remnant silhouette in grey, per spectral class."

So we have 5x5 input grid with one color (B, R, G, etc). The output is a 3x3 grid of X's (grey) and . (black). The shape depends on the color. The training examples show mapping from input to output.

We need to deduce the rule: For each color, there is a fixed 3x3 pattern of X's. The input grid contains that color scattered across the 5x5 grid. The output is the shape of the remnant silhouette in grey. So the shape is determined solely by the color, not by the arrangement of the stars. So we need to map each color to a 3x3 pattern.

We have training examples for colors B, R, G. Let's analyze each.

Example 1: Input has B stars. Output:

. X .
X X X
. X .

So for B, the pattern is:

Row1: . X .
Row2: X X X
Row3: . X .

That's a cross shape (plus shape) with center and arms.

Example 2: Input has R stars. Output:

X X X
. X .
. X .

So for R, pattern:

Row1: X X X
Row2: . X .
Row3: . X .

That's like a vertical line on the right side? Wait let's map coordinates: 3x3 grid indices (row, col). For R: row1: X X X (all X). row2: . X . (only center). row3: . X . (only center). So shape: top row full, then two rows with only center X. That's like a T shape rotated? Actually it's like a vertical line on the right? Wait center X is at column 2 (index 1). So row2 col2 X, row3 col2 X. So shape: top row all X, then two rows with only center X. So shape is like a "T" with the stem downwards? Actually a T shape would have top row all X, and center X below. But here we have two X's below center. So it's like a T with a longer stem. So shape: top row full, then two rows with only center X. So shape is like a "T" with a vertical line of length 3 (including top row). So basically a vertical line of length 3, but with top row extended horizontally. So shape: a vertical line of 3 X's in the center column, plus the top row all X's. So shape: a "T" shape with a longer stem.

Example 3: Input has G stars. Output:

. . X
. . X
X X X

So for G: pattern:

Row1: . . X
Row2: . . X
Row3: X X X

That's like a rotated L shape: vertical line on right side (two X's) plus bottom row all X's. So shape: a "L" shape rotated 90 degrees? Actually it's like a "Γ" shape: vertical line on right side, bottom row all X's. So shape: a "Γ" shape.

Example 4: Input has B stars again. Output:

. X .
X X X
. X .

Same as Example 1. So B pattern is consistent.

Thus we have mapping:

Color B -> pattern:
. X .
X X X
. X .

Color R -> pattern:
X X X
. X .
. X .

Color G -> pattern:
. . X
. . X
X X X

We need to produce output for test input: color G. So output should be same as G pattern: . . X / . . X / X X X.

But we need to confirm that the test input indeed has G stars. Let's check test input:

Test Input:
. G . G G
. . G . .
G . . . .
. . G . G
. . . . G

Yes, all stars are G. So output should be G pattern.

But we need to double-check that the mapping is indeed color-based and not something else. Let's analyze the training examples more thoroughly to ensure no other hidden rule.

We have 5x5 input grid with one color. The output is 3x3 grid of X's and . . The shape is fixed per color. The mapping we found seems plausible.

But we should also consider if the shape might be derived from the arrangement of stars in the input. But the description says "Classify the spectral type by color and predict the stellar remnant — a small fixed shape that spectral class alone determines." So indeed shape depends only on color.

Thus we can produce output for G.

But let's double-check the mapping for G: In Example 3, the output is:

. . X
. . X
X X X

Yes.

Now we need to produce the output grid in the required format: each row on a new line, characters separated by spaces? The instructions: "At the very end of your response, write the complete output grid inside a clearly labeled block like this:
ANSWER:
. B R
G Y .
(one row per line, characters separated by spaces)"

So we need to output:

ANSWER:
. . X
. . X
X X X

But we need to separate characters by spaces. So each row: ". . X" etc.

Thus final answer:

ANSWER:
. . X
. . X
X X X

But we need to ensure we follow the format exactly: "ANSWER:" on its own line, then the grid lines. Each row: characters separated by spaces. So:

ANSWER:
. . X
. . X
X X X

Yes.

But let's double-check the mapping for R: In Example 2, output is:

X X X
. X .
. X .

Yes.

Now, we should also consider if there might be any other colors in the test input. The test input only has G. So we output G pattern.

But we should also consider if the shape might be rotated or mirrored depending on something else. But the descripti

We need to solve a grid transformation puzzle. We have training examples. Input is 5x5 grid with one color (B, R, G). Output is 3x3 grid with X's and . (black). The description: "Floating debris of one color scattered across dark ocean. Identify the cargo type by its color and assign the mooring configuration — each cargo has one berth pattern, regardless of where the flotsam drifts. Grid details: Input: 5x5 ocean with one cargo color. Output: 3x3 mooring pattern in grey, fixed per cargo."

So the rule: For each color (B, R, G), there is a fixed 3x3 pattern of X's and . that is output. The input 5x5 grid contains scattered cells of that color. The output is the pattern for that color. So we need to map each color to a 3x3 pattern.

We have three training examples: Example 1: Input has B cells. Output is a 3x3 pattern with X's and . . Let's record.

Example 1 Input: 5x5 grid with B cells. Output: 3x3 grid:

Row1: . X .
Row2: X X X
Row3: . X .

So pattern for B: 
```
. X .
X X X
. X .
```

Example 2 Input: R cells. Output: 3x3 grid:

Row1: X X X
Row2: . X .
Row3: . X .

So pattern for R: 
```
X X X
. X .
. X .
```

Example 3 Input: G cells. Output: 3x3 grid:

Row1: . . X
Row2: . . X
Row3: X X X

So pattern for G: 
```
. . X
. . X
X X X
```

Now test input: 5x5 grid with G cells. So we need to output the pattern for G: same as Example 3. So output should be:

Row1: . . X
Row2: . . X
Row3: X X X

But we need to confirm that the pattern is indeed fixed per color. Let's double-check that the patterns are consistent across examples. For B, pattern is symmetrical cross shape. For R, pattern is top row all X, then two X's in column 2? Wait pattern for R: 
```
X X X
. X .
. X .
```
So it's like a vertical line of X's in column 2, plus top row all X. For G, pattern is vertical line of X's in column 3, plus bottom row all X. So each color has a pattern that is rotated or mirrored? Let's analyze.

B pattern: cross shape: X's at center row and center column. So shape: plus sign. R pattern: top row all X, plus vertical line at column 2. G pattern: bottom row all X, plus vertical line at column 3. So each color has a pattern that is rotated 90 degrees? Let's see: B pattern is plus sign. R pattern is like a rotated plus sign? Actually plus sign rotated 90 degrees is same shape. But R pattern is not plus sign. Wait plus sign shape: X at (1,1), (1,2), (1,3), (2,1), (2,2), (2,3), (3,1), (3,2), (3,3) but with center? Actually plus sign shape would be X at center row and center column: positions (1,2), (2,1),(2,2),(2,3),(3,2). That's exactly B pattern: . X . / X X X / . X . So B pattern is plus sign.

R pattern: top row all X: (1,1),(1,2),(1,3). Then vertical line at column 2: (2,2),(3,2). So shape: a T shape? Actually it's like a T shape rotated 90 degrees? Let's think: plus sign rotated 90 degrees is same shape. But R pattern is like a T shape: top row all X, plus vertical line at center column. That is a T shape. G pattern: bottom row all X, plus vertical line at column 3: shape like a reversed T? Actually bottom row all X: (3,1),(3,2),(3,3). Then vertical line at column 3: (1,3),(2,3). So shape: a T shape rotated 180 degrees? Wait T shape rotated 180 degrees would have bottom row all X and vertical line at center column. But G pattern has vertical line at column 3, not center. So it's not symmetrical.

But maybe the pattern is determined by the color's position relative to something else? But the description says "each cargo has one berth pattern, regardless of where the flotsam drifts." So pattern is fixed per color. So we just need to output the pattern for G.

Thus answer: 
```
. . X
. . X
X X X
```

But we need to output with spaces between characters? The instructions: "At the very end of your response, write the complete output grid inside a clearly labeled block like this: ANSWER: . B R G Y ."

So we need to output:

ANSWER:
. . X
. . X
X X X

But we need to ensure we use spaces between characters. The example answer block shows each row on a new line, characters separated by spaces. So we need to produce:

ANSWER:
. . X
. . X
X X X

But we need to confirm that the output grid uses the same format as training examples: In the training examples, the output grid is shown as:

Example 1 Output:
. X .
X X X
. X .

They didn't show spaces between characters. But the final answer block requires spaces. The instructions: "write the complete output grid inside a clearly labeled block like this: ANSWER: . B R G Y . (one row per line, characters separated by spaces)". So we need to output with spaces.

Thus final answer:

ANSWER:
. . X
. . X
X X X

But we need to double-check that the pattern for G is indeed . . X / . . X / X X X. Let's confirm by analyzing Example 3 input and output.

Example 3 Input:
```
. G . G .
G G . . .
. G . . .
. . G . .
G G G . .
```
Output:
```
. . X
. . X
X X X
```

So pattern for G is as above. So we can output that.

But we should also consider if there might be any other transformation rule

We need to solve a grid transformation puzzle. We have training examples: Input 5x5 grid with one dopant color (B, R, G). Output 3x3 grid with X's and . (grey and black). The transformation rule: identify dopant by color and read off the junction geometry — a fixed output pattern intrinsic to that impurity type. So each dopant color corresponds to a fixed 3x3 pattern of X's and . (maybe rotated or mirrored?). Let's analyze training examples.

Example 1: Input 5x5 with B (blue). Output 3x3 pattern:

. X .
X X X
. X .

So for blue, output pattern is:

Row1: . X .
Row2: X X X
Row3: . X .

Example 2: Input 5x5 with R (red). Output:

X X X
. X .
. X .

So for red, output pattern is:

Row1: X X X
Row2: . X .
Row3: . X .

Example 3: Input 5x5 with G (green). Output:

. . X
. . X
X X X

So for green, output pattern is:

Row1: . . X
Row2: . . X
Row3: X X X

So each color has a unique 3x3 pattern. The transformation rule: identify dopant color and output its fixed pattern. But maybe the pattern is derived from the arrangement of dopant cells in the 5x5 input? Let's examine the inputs to see if the pattern is derived from the positions of the dopant cells relative to something. But the description says: "Identify the dopant by its color and read off the junction geometry — a fixed output pattern intrinsic to that impurity type." That suggests the output pattern is predetermined for each color, not derived from the input arrangement. But we need to confirm.

Let's analyze Example 1 input: 5x5 grid with B cells. Let's map coordinates (row, col) 1-indexed. Input:

Row1: B . B . .
Row2: B . . B B
Row3: B B . B .
Row4: . B . B .
Row5: B . . . B

Let's mark B positions:

(1,1), (1,3)
(2,1), (2,4), (2,5)
(3,1), (3,2), (3,4)
(4,2), (4,4)
(5,1), (5,5)

So B cells are many. The output pattern is . X . / X X X / . X . . That pattern is symmetrical. But is it derived from the arrangement? Let's see if the pattern corresponds to some shape of B cells? For example, maybe the output pattern is the shape of the B cells when rotated or scaled? But the output pattern is 3x3, while input is 5x5. Maybe we need to find the bounding box of B cells, then shrink to 3x3? Let's check bounding box: min row = 1, max row = 5; min col = 1, max col = 5. So bounding box is entire grid. But output is 3x3. So not bounding box.

Maybe we need to find the "junction geometry" of the dopant: maybe the arrangement of B cells relative to each other forms a shape that can be represented as a 3x3 pattern of X's and .? But the output pattern for B is . X . / X X X / . X . . That shape is like a cross shape (plus sign). But the B cells in input: Let's see if they form a cross shape? Let's overlay a 3x3 cross shape onto the 5x5 grid: The cross shape has center at (3,3) maybe? But B cells at (3,3) is '.' not B. So not.

Maybe the output pattern is derived from the arrangement of B cells relative to the center of the grid? Let's compute the center of the grid: (3,3). B cells relative to center: (1,1) is (-2,-2), (1,3) is (-2,0), (2,1) is (-1,-2), (2,4) is (-1,1), (2,5) is (-1,2), (3,1) is (0,-2), (3,2) is (0,-1), (3,4) is (0,1), (4,2) is (1,-1), (4,4) is (1,1), (5,1) is (2,-2), (5,5) is (2,2). So B cells are at many positions. The output pattern . X . / X X X / . X . has X's at positions: (1,2), (2,1),(2,2),(2,3),(3,2). That is a cross shape. But B cells are not exactly at those positions. So output pattern is not derived from B positions.

Maybe the output pattern is predetermined for each color. Let's check Example 2: Input with R cells. Output pattern: X X X / . X . / . X . . That shape is like a diagonal line from top-left to bottom-right? Actually pattern: Row1: X X X (positions (1,1),(1,2),(1,3)). Row2: . X . (positions (2,2)). Row3: . X . (positions (3,2)). So shape is like a vertical line at column 2 from row 2 to 3, plus a horizontal line at row 1 across all columns. So shape is like a T shape rotated? Not exactly.

Example 3: Input with G cells. Output pattern: . . X / . . X / X X X. That shape is like a vertical line at column 3 from row 1 to 2, plus a horizontal line at row 3 across all columns. So shape is like a T shape rotated 180 degrees? Actually it's like a T shape rotated 90 degrees? Let's analyze: For G, output pattern: Row1: . . X (X at (1,3)). Row2: . . X (X at (2,3)). Row3: X X X (X at (3,1),(3,2),(3,3)). So shape is like a vertical line at column 3 from row 1 to 2, plus a horizontal line at row 3 across all columns. That is like a T shape rotated 90 degrees clockwise? Wait, a T shape rotated 90 degrees clockwise would have a horizontal line at top and vertical line at right? Actually a T shape rotated 90 degrees clockwise would have a horizontal line at top and vertical line at right side. But here we have horizontal line at bottom and vertical line at right side. That is a T shape rotated 180 degrees? Let's think: Standard T shape: horizontal line at top, vertical line at center. Rotated 180 degrees: horizontal line at bottom,

We need to solve a grid transformation puzzle. We have training examples: Example 1, 2, 3. Input grids are 5x5, output grids are 3x3. The transformation seems to involve a single color (the "sacred color") in the input. The output is a 3x3 grid of X's (grey) and . (black). The output pattern seems to be a "glyph" that is fixed per deity (color). The description: "Oracle bones tinted in one deity's sacred color, scattered across a dark cloth. Read the dye color to identify the deity and inscribe the sacred glyph — each god commands one eternal symbol, indifferent to how the bones fell." So the input grid has a single color (like B, R, G). The output is a 3x3 pattern of X's and . that is fixed for that color. So we need to map each color to a 3x3 pattern. The training examples show mapping for B, R, G. We need to deduce the pattern for G (green) from Example 3. Then apply to test input which is also green. So we need to produce the 3x3 pattern for green.

But we need to confirm that the output pattern is indeed fixed per color, not dependent on arrangement. Let's analyze each example.

Example 1: Input 5x5 with B's scattered. Output 3x3 pattern:

. X .
X X X
. X .

So pattern for B is:

Row1: . X .
Row2: X X X
Row3: . X .

Example 2: Input 5x5 with R's scattered. Output:

X X X
. X .
. X .

So pattern for R is:

Row1: X X X
Row2: . X .
Row3: . X .

Example 3: Input 5x5 with G's scattered. Output:

. . X
. . X
X X X

So pattern for G is:

Row1: . . X
Row2: . . X
Row3: X X X

Thus we have mapping:

B -> pattern1
R -> pattern2
G -> pattern3

Now test input is also G. So output should be pattern3.

But we need to double-check that the mapping is indeed fixed per color. Let's examine the input patterns to see if they match any transformation rule that might produce the output pattern. But the description says "indifferent to how the bones fell" meaning the arrangement of the colored cells in the input doesn't matter; only the color matters. So the output is predetermined for each color. So we just need to output the pattern for G.

But we should confirm that the output pattern for G is indeed as we deduced. Let's double-check Example 3 input and output.

Example 3 Input:

Row1: . G . G .
Row2: G G . . .
Row3: . G . . .
Row4: . . G . .
Row5: G G G . .

Output:

Row1: . . X
Row2: . . X
Row3: X X X

Yes.

Now test input:

Row1: . G . G G
Row2: . . G . .
Row3: G . . . .
Row4: . . G . G
Row5: . . . . G

We need to output the same pattern for G: . . X / . . X / X X X.

But we should confirm that the output pattern is indeed 3x3. Yes.

Now we need to produce the output grid in the required format: each row on a new line, characters separated by spaces. The output grid should be:

. . X
. . X
X X X

But we need to check if the output uses X for grey and . for black. Yes.

Now we need to produce the final answer block:

ANSWER:
. . X
. . X
X X X

But we need to ensure that we follow the instructions: "At the very end of your response, write the complete output grid inside a clearly labeled block like this: ANSWER: . B R G Y ."

So we need to produce:

ANSWER:
. . X
. . X
X X X

But we need to separate characters by spaces. So each row: ". . X" etc.

Thus final answer:

ANSWER:
. . X
. . X
X X X

But we need to double-check if there is any nuance: The output pattern for G might be rotated or mirrored? Let's examine the patterns for B and R to see if they are rotated or mirrored relative to each other. Pattern for B: . X . / X X X / . X . (like a cross shape). Pattern for R: X X X / . X . / . X . (like a rotated cross). Pattern for G: . . X / . . X / X X X (like a rotated cross again? Actually it's like a diagonal shape? Let's analyze.

Pattern for B: cross shape with center X and arms up, down, left, right? Actually pattern for B: Row1: . X . (X at center top). Row2: X X X (full row). Row3: . X . (X at center bottom). So it's like a vertical line of X's at center column, plus a horizontal line at middle row. So it's a plus shape.

Pattern for R: Row1: X X X (full row). Row2: . X . (X at center). Row3: . X . (X at center). So it's like a vertical line at center column plus a horizontal line at top row. So it's like a rotated plus shape? Actually it's like a plus shape rotated 90 degrees? Let's think: The plus shape for B has horizontal line at middle row, vertical line at center column. For R, horizontal line at top row, vertical line at center column. So it's like the plus shape rotated 90 degrees? But the plus shape rotated 90 degrees would have horizontal line at top row? Wait, rotating the plus shape 90 degrees would produce the same shape: horizontal line at top row, vertical line at center column. So yes, R pattern is the plus shape rotated 90 degrees relative to B. But the plus shape rotated 90 degrees is the same shape because plus shape is symmetric under 90-degree rotation. But the difference is that the horizontal line is at top row instead of middle row. So it's like a plus shape but with horizonta

We need to solve a grid transformation puzzle. We have training examples: Example 1, 2, 3. Input grids are 5x5, output grids are 3x3. The transformation seems to produce a 3x3 pattern of X's and . (black). The input has one color (B, R, G). The output is a 3x3 pattern of X's and . (grey and black). The description: "What you see: Dancers in one color of slippers scattered across a dark stage. What to do: Identify the company by slipper color and call the signature lift — a compact formation each company always performs, regardless of starting positions. Grid details: Input: 5x5 stage with one slipper color. Output: 3x3 lift formation in grey, unique per company."

So each color corresponds to a unique 3x3 pattern of X's and . (maybe representing a shape). The pattern is independent of the positions of the colored cells in the input; it's a fixed pattern for each color. The input grid is 5x5 with scattered cells of that color. The output is a 3x3 pattern of X's and . that is unique per color. So we need to deduce the mapping from color to pattern.

We have three training examples: Example 1: color B (blue). Input grid has B's scattered. Output grid is:

. X .
X X X
. X .

So for B, the pattern is:

Row1: . X .
Row2: X X X
Row3: . X .

Example 2: color R (red). Output grid:

X X X
. X .
. X .

So for R, pattern is:

Row1: X X X
Row2: . X .
Row3: . X .

Example 3: color G (green). Output grid:

. . X
. . X
X X X

So for G, pattern is:

Row1: . . X
Row2: . . X
Row3: X X X

Thus we have mapping:

B -> pattern1
R -> pattern2
G -> pattern3

Now test input: color G. So we need to output pattern for G: . . X / . . X / X X X.

But we need to confirm that the mapping is indeed unique per color. Let's double-check the patterns.

Example 1: B pattern: . X . / X X X / . X . (like a cross shape with center and arms). Example 2: R pattern: X X X / . X . / . X . (like a vertical line on right side plus top row). Example 3: G pattern: . . X / . . X / X X X (like a vertical line on right side plus bottom row). Wait, R pattern: top row all X, second row has X at center, third row has X at center. G pattern: top row has X at rightmost, second row has X at rightmost, third row has X X X. So R pattern is top row all X, then vertical line on center? Actually second row: . X . (center X). Third row: . X . (center X). So vertical line on center. G pattern: vertical line on rightmost, plus bottom row all X. B pattern: vertical line on center, horizontal line on bottom row? Wait B pattern: . X . / X X X / . X . So vertical line on center, horizontal line on middle row. So each pattern is a shape of 3x3.

Now test input: . G . G G / . . G . . / G . . . . / . . G . G / . . . . G

We need to output the pattern for G: . . X / . . X / X X X.

But we need to confirm that the output grid is 3x3. Yes. So answer should be:

. . X
. . X
X X X

But we need to output with spaces between characters? The instructions: "write the complete predicted output grid using these single-character color codes: Color key: .=black B=blue R=red G=green Y=yellow X=grey M=magenta O=orange A=azure W=maroon. At the very end of your response, write the complete output grid inside a clearly labeled block like this: ANSWER: . B R G Y ."

So we need to output:

ANSWER:
. . X
. . X
X X X

But we need to check if the output grid uses spaces between characters. The example shows "ANSWER: . B R G Y .". That is a single line with spaces. But the instructions say "one row per line, characters separated by spaces". So we need to output each row on a new line, with characters separated by spaces. So we need:

ANSWER:
. . X
. . X
X X X

But we need to confirm that the output grid uses spaces between characters. The example shows "ANSWER: . B R G Y .". That is a single line. But the instruction says "one row per line, characters separated by spaces". So we need to output:

ANSWER:
. . X
. . X
X X X

Yes.

But we need to double-check the mapping: Are we sure that the pattern for G is . . X / . . X / X X X? Let's verify with Example 3. Example 3 input: . G . G . / G G . . . / . G . . . / . . G . . / G G G . . Output: . . X / . . X / X X X. Yes.

Thus the answer is that.

But let's double-check the puzzle description: "What you see: Dancers in one color of slippers scattered across a dark stage. What to do: Identify the company by slipper color and call the signature lift — a compact formation each company always performs, regardless of starting positions. Grid details: Input: 5x5 stage with one slipper color. Output: 3x3 lift formation in grey, unique per company."

So indeed each color corresponds to a unique 3x3 pattern. The input grid is 5x5 with scattered colored cells. The output is a 3x3 pattern of X's and . that is unique per color. So we just need to output the pattern for G.

Thus answer: . . X / . . X / X X X.

But we need to ensure that we output exactly as required: "ANSWER:" then the grid. The grid lines should have spaces between characters. So:

We need to solve a grid transformation puzzle. We have training examples: Input 5x5 grid with one ore color (like B, R, G). Output 3x3 grid with X's and . (grey and black). The transformation rule: Identify the mineral by ore color and predict its crystal habit — a compact lattice unique to that mineral, independent of vein placement. So the output is a 3x3 pattern of X's and . that is fixed per mineral color. The input shows the ore color scattered through a black background. The output is a 3x3 pattern of X's and . that is the "crystal habit" for that mineral. So we need to deduce the mapping from color to 3x3 pattern.

We have 3 training examples:

Example 1: Input 5x5 with B (blue). Output 3x3 pattern:

. X .
X X X
. X .

Example 2: Input 5x5 with R (red). Output 3x3 pattern:

X X X
. X .
. X .

Example 3: Input 5x5 with G (green). Output 3x3 pattern:

. . X
. . X
X X X

We need to find mapping from color to pattern. Then apply to test input: G (green). So we need to output the pattern for green. But we already have pattern for green from example 3. But we need to confirm that the pattern is indeed fixed per mineral. The test input is also green. So output should be same as example 3: . . X / . . X / X X X. But we need to double-check if there is any nuance: maybe the pattern is rotated or mirrored depending on orientation of ore? But the description says "independent of vein placement". So the pattern is fixed per mineral, not dependent on arrangement. So we can just output the pattern for green.

But we should confirm that the mapping is indeed fixed: For B, pattern is:

Row1: . X .
Row2: X X X
Row3: . X .

For R, pattern is:

Row1: X X X
Row2: . X .
Row3: . X .

For G, pattern is:

Row1: . . X
Row2: . . X
Row3: X X X

We need to check if there is any other pattern for other colors? Not needed.

But we should confirm that the mapping is indeed unique: For B, pattern is symmetrical horizontally? Actually B pattern is symmetrical vertically? Let's analyze:

B pattern:

Row1: . X .
Row2: X X X
Row3: . X .

This is like a plus shape rotated 90 degrees? Actually it's like a cross shape: center row all X, center column all X. So it's a plus shape.

R pattern:

Row1: X X X
Row2: . X .
Row3: . X .

This is like a vertical line on right side plus top row all X. So shape like a "Γ" shape? Actually it's like a right-angled shape: top row all X, right column all X. So it's like a corner shape.

G pattern:

Row1: . . X
Row2: . . X
Row3: X X X

This is like a rotated version of R pattern: bottom row all X, right column all X. So it's like a corner shape rotated 180 degrees? Actually R pattern is top row all X, right column all X. G pattern is bottom row all X, right column all X. So it's like a corner shape rotated 180 degrees? Wait, R pattern: top row all X, right column all X. G pattern: bottom row all X, right column all X. So it's like a corner shape rotated 180 degrees? Actually if you rotate R pattern 180 degrees, you get bottom row all X, left column all X. But G pattern has right column all X. So it's not a rotation. It's like a corner shape but on the right side. R pattern: top row all X, right column all X. G pattern: bottom row all X, right column all X. So it's like a corner shape but at the bottom right corner. So maybe the mapping is: B -> plus shape; R -> top-right corner; G -> bottom-right corner. But we need to confirm if there is any other pattern for other colors? Not needed.

But we need to produce the output grid for test input: G. So output should be:

. . X
. . X
X X X

But we need to confirm that the output grid uses the same format: 3x3 grid with X and . separated by spaces? The examples show output as:

Example 1 Output:
. X .
X X X
. X .

They show each row on a new line, with spaces between characters. So we need to output the same.

Thus answer:

. . X
. . X
X X X

But we need to double-check if there is any nuance: The test input is:

. G . G G
. . G . .
G . . . .
. . G . G
. . . . G

We need to confirm that the input is 5x5 with G's scattered. The output should be 3x3 pattern for G. So we can output the pattern.

But we should also consider if the pattern might be rotated or mirrored based on orientation of ore? But the description says "independent of vein placement". So the pattern is fixed per mineral. So we can output the pattern.

But we should also consider if the pattern might be rotated based on the orientation of the ore cluster? But the description says "independent of vein placement". So no.

Thus answer: . . X / . . X / X X X.

But we need to ensure we output the grid with spaces between characters. So final answer:

ANSWER:
. . X
. . X
X X X

But we need to check if the output grid uses spaces or not. The examples show spaces between characters. So we should follow that.

Thus final answer:

But we need to double-check if the output grid uses spaces or not. The examples show:

We need to solve a grid transformation puzzle. We have training examples: Input 5x5 grid with colored cells (B, R, G) and '.' for black. Output 3x3 grid with X's and '.'.

We need to deduce rule: For each color, there is a unique pattern of X's in 3x3 output. The input has a single colored spice scattered randomly across a 5x5 board. The output is a 3x3 pattern of grey (X) that corresponds to the spice identity. So we need to map each color to a 3x3 pattern. The input grid has only one color present? Let's check training examples.

Example 1 Input: 5x5 grid with B cells. Let's list coordinates of B's. Input grid:

Row1: B . B . .
Row2: B . . B B
Row3: B B . B .
Row4: . B . B .
Row5: B . . . B

So B cells at positions: (1,1),(1,3),(2,1),(2,4),(2,5),(3,1),(3,2),(3,4),(4,2),(4,4),(5,1),(5,5). That's many B's. So not a single spice? Wait the description says "single spice sprinkled haphazardly across a dark surface." But the input has many B's. But maybe the "spice" refers to the color B, and the pattern of B's across the board is random but we need to identify the pattern of X's that corresponds to that color. So each color has a unique 3x3 pattern. The input grid may contain many cells of that color, but we need to deduce the pattern from the arrangement of that color across the 5x5 board. The output is a 3x3 pattern of X's that is the "signature garnish" for that color.

Thus we need to map each color to a 3x3 pattern. We have training examples for B, R, G. We need to deduce the mapping.

Let's analyze Example 1: Input B pattern. Output 3x3:

. X .
X X X
. X .

So pattern:

Row1: . X .
Row2: X X X
Row3: . X .

This is a cross shape: center row all X, center column all X, but corners are '.'.

So for B, the pattern is cross shape.

Example 2: Input R pattern. Output 3x3:

X X X
. X .
. X .

So pattern:

Row1: X X X
Row2: . X .
Row3: . X .

This is like a vertical line on right side? Wait let's map coordinates: 3x3 grid indices (row, col). Row1: X X X (all X). Row2: . X . (only center). Row3: . X . (only center). So shape: top row all X, then a vertical line of X's in center column from row2 to row3. So shape like a T rotated? Actually it's like a T shape with top horizontal line and vertical line down from center. But the vertical line extends only two cells (rows 2 and 3). So shape: top row full, center column full (rows 1-3). But top row already has X at center, so center column is X at all rows. So shape is like a T shape with top horizontal line and vertical line down from center. But the vertical line extends to bottom row as well? Wait row3 center is X, yes. So center column all X. So shape is like a cross but missing left and right arms at bottom? Actually cross shape would have center row all X and center column all X. But here we have top row all X, center column all X. So missing bottom row left and right cells. So shape is like a "Γ" shape? Let's analyze: 3x3 grid:

Positions:
(1,1) X
(1,2) X
(1,3) X
(2,1) .
(2,2) X
(2,3) .
(3,1) .
(3,2) X
(3,3) .

So shape: X at (1,1),(1,2),(1,3),(2,2),(3,2). So it's like a vertical line in column 2, plus top row all X. So shape is like a "T" rotated 90 degrees? Actually a T shape would have top row all X and center column all X, but also bottom row center X? Wait T shape: top row all X, center column all X, but bottom row center X? That would be same as this shape: top row all X, center column all X. But bottom row center X is included. So shape is exactly a T shape. But cross shape would have center row all X and center column all X. So R pattern is T shape.

Example 3: Input G pattern. Output 3x3:

. . X
. . X
X X X

So pattern:

Row1: . . X
Row2: . . X
Row3: X X X

Positions: (1,3),(2,3),(3,1),(3,2),(3,3). So shape: bottom row all X, right column all X. So shape is like a rotated T shape? Actually it's like a T shape rotated 180 degrees? Let's analyze: For R pattern, we had top row all X, center column all X. For G pattern, we have bottom row all X, right column all X. So it's like a T shape rotated 180 degrees? Wait T shape rotated 180 degrees would have bottom row all X and center column all X. But here we have right column all X, not center column. So it's like a T shape rotated 90 degrees? Let's examine: R pattern: top row all X, center column all X. G pattern: bottom row all X, right column all X. So it's like a T shape rotated 90 degrees clockwise? Let's rotate R pattern 90 degrees clockwise: top row all X becomes right column all X. Center column all X becomes bottom row all X. So rotated R pattern would be: right column all X, bottom row all X. That matches G pattern exactly. So G pattern is R pattern rotated 90 degrees clockwise. So G pattern is a rotated T shape.

Thus we have mapping: B -> cross shape. R -> T shape (top row + center column). G -> rotated T shape (bottom row + right column). So each color has a unique pattern.

Now we need to apply to test input: Input grid 5x5 with G cells. Let's examine test input:

Row1: . G . G G
Ro

... [8263 chars truncated]

We need to solve a grid transformation puzzle. We have training examples: Input 5x5 grid with one color (B, R, G). Output 3x3 grid with X's and . (grey and black). The description: "Random notes written in a single instrument's color of ink splashed across a dark staff. Recognize the instrument by its ink color and play its signature riff — a compact motif that never changes regardless of what was written on the page. Input: 5x5 staff with one ink color. Output: 3x3 riff pattern in grey, fixed per instrument."

So each instrument (color) has a fixed 3x3 pattern of X's and . (grey and black). The input grid is 5x5 with that color ink scattered. The output is the fixed pattern for that color. So we need to deduce the pattern for each color from training examples.

We have 3 training examples: Example 1 uses B (blue). Example 2 uses R (red). Example 3 uses G (green). We need to find the 3x3 pattern for each color.

Let's analyze each example.

Example 1 Input (5x5):

Row1: B . B . .
Row2: B . . B B
Row3: B B . B .
Row4: . B . B .
Row5: B . . . B

Output (3x3):

Row1: . X .
Row2: X X X
Row3: . X .

So for B, the pattern is:

. X .
X X X
. X .

Let's confirm that this pattern is consistent with the description: "compact motif that never changes regardless of what was written on the page." So yes.

Example 2 Input (5x5):

Row1: R . R . R
Row2: R . . . R
Row3: R R . . .
Row4: R . . R R
Row5: R R R . R

Output (3x3):

Row1: X X X
Row2: . X .
Row3: . X .

So for R, pattern:

X X X
. X .
. X .

Example 3 Input (5x5):

Row1: . G . G .
Row2: G G . . .
Row3: . G . . .
Row4: . . G . .
Row5: G G G . .

Output (3x3):

Row1: . . X
Row2: . . X
Row3: X X X

So for G, pattern:

. . X
. . X
X X X

Now we need to produce output for test input: 5x5 grid with G color. So we need to output the pattern for G: . . X / . . X / X X X.

But we must double-check that the pattern for G is indeed that. Let's verify by mapping the input to output: The input grid for G is:

Row1: . G . G G
Row2: . . G . .
Row3: G . . . .
Row4: . . G . G
Row5: . . . . G

We need to confirm that the pattern for G is indeed . . X / . . X / X X X. Let's check if there is any other pattern that could produce that output. But the training example 3 shows that pattern. So we can output that.

But we should also consider if the pattern might be rotated or mirrored depending on orientation. But the description says "signature riff — a compact motif that never changes regardless of what was written on the page." So it's fixed. So we just output the pattern for G.

Thus the answer is:

. . X
. . X
X X X

But we need to output with spaces between characters? The instructions: "write the complete output grid inside a clearly labeled block like this: ANSWER: . B R G Y .". They show each row on a new line, characters separated by spaces. So we need to output:

ANSWER:
. . X
. . X
X X X

But we need to confirm that the output uses spaces between characters. In the example they show:

ANSWER:
. B R
G Y .

So yes, each row is characters separated by spaces. So we need to output:

ANSWER:
. . X
. . X
X X X

But we need to check if the output grid uses spaces or not. The example shows "ANSWER: . B R G Y .". Actually the example shows:

ANSWER:
. B R
G Y .

So each row is separated by newline, and each character separated by space. So we will follow that.

Thus final answer:

ANSWER:
. . X
. . X
X X X

But we need to double-check that the pattern for G is indeed . . X / . . X / X X X. Let's confirm by analyzing the input for G. The input grid for G is:

Row1: . G . G G
Row2: . . G . .
Row3: G . . . .
Row4: . . G . G
Row5: . . . . G

We can try to see if the pattern for G might be something else. But the training example 3 shows that pattern. So we can trust that.

But let's double-check the training example 3 input and output to ensure we didn't misinterpret. Example 3 Input:

Row1: . G . G .
Row2: G G . . .
Row3: . G . . .
Row4: . . G . .
Row5: G G G . .

Output:

Row1: . . X
Row2: . . X
Row3: X X X

So the pattern for G is indeed . . X / . . X / X X X.

Now we need to produce output for test input. The test input is also G. So output should be same pattern.

Thus final answer: . . X / . . X / X X X.

But we need to ensure that we output exactly 3 rows, each with 3 characters separated by spaces. So:

ANSWER:
. . X
. . X
X X X

Yes.

But let's double-check if there might be any nuance: The description says "Random notes written in a single instrument's color of ink splashed across a dark staff." So the input grid is 5x5 with one color. The output is 3x3 pattern in grey, fixed per instrument. So we just output the pattern for G.

Thus final answer: . . X / . . X / X X X.

But we should also consider if the pattern might be rotated or mirrored depending on orientation of the input. But the description says "signature riff — a compact motif that never changes regardless of what was written on the page." So it's fixed. So no rotation.

Thus final answer: . . X / .

We need to solve a grid transformation puzzle. We have training examples: Input 5x5 grid with one color scattered (B, R, G). Output 3x3 grid with X's and . (grey and black). The description: "Players in matching jerseys scattered across a dark playing field. Identify the jersey color and call the team's one and only formation — a compact tactical shape burned into their playbook. Input: 5x5 field with one jersey color scattered. Output: 3x3 formation diagram in grey, unique to that team."

So we need to find a rule mapping the 5x5 grid of a single color (B, R, G) scattered across the grid to a 3x3 pattern of X's and . (grey and black). The output pattern seems to be a shape that is unique to each color. The shape is "compact tactical shape burned into their playbook." So each color has a unique 3x3 pattern. The input grid is 5x5 with scattered cells of that color. The output is a 3x3 pattern of X's and . that is unique to that color. So we need to deduce mapping from color to pattern.

We have 3 training examples: Example 1: Input has B scattered. Output pattern: 
. X .
X X X
. X .
So pattern is a cross shape: center row all X, center column all X, but corners are . . . Actually pattern: row1: . X . ; row2: X X X ; row3: . X . . That's a plus shape. So for B, pattern is plus shape.

Example 2: Input has R scattered. Output pattern:
X X X
. X .
. X .
So pattern: row1: X X X ; row2: . X . ; row3: . X . . That's like a vertical line on right side? Wait let's map coordinates: 3x3 grid: positions (row, col). Row1: X X X (all X). Row2: . X . (only center X). Row3: . X . (only center X). So shape: top row all X, then a vertical line of X's in center column from row2 to row3. So shape is like a T rotated? Actually it's like a shape with top row full, then a vertical line down the center column. So shape: a "T" shape but with the stem downwards? Wait typical T shape would have top row all X, then center column X's below. Yes that's exactly a T shape. So for R, pattern is a T shape.

Example 3: Input has G scattered. Output pattern:
. . X
. . X
X X X
So pattern: row1: . . X ; row2: . . X ; row3: X X X. That's like a rotated T shape? Actually it's like a T shape rotated 180 degrees? Let's see: For R, we had top row all X, center column X's below. For G, we have bottom row all X, center column X's above? Wait bottom row all X, center column X's above. So it's like a T shape rotated 180 degrees (pointing downwards). So for G, pattern is a T shape rotated 180 degrees (pointing downwards). For B, pattern is a plus shape. So we have 3 colors mapping to 3 patterns: B -> plus, R -> T shape pointing up, G -> T shape pointing down. But we need to confirm orientation: For R, top row all X, center column X's below. That is a T shape pointing up? Actually typical T shape pointing up would have top row all X, center column X's below. Yes that is a T shape pointing up. For G, bottom row all X, center column X's above. That is a T shape pointing down. So indeed.

Now we need to apply to test input: Input grid 5x5 with G scattered. Wait test input: 
. G . G G
. . G . .
G . . . .
. . G . G
. . . . G

So the color is G. So we need to output the pattern for G: . . X / . . X / X X X. But we need to confirm that the pattern is indeed unique to G. But we should double-check that the mapping is consistent across all examples. Let's analyze each example in detail.

Example 1: Input 5x5 with B scattered. Output pattern: . X . / X X X / . X . . That is a plus shape. So B -> plus shape.

Example 2: Input 5x5 with R scattered. Output pattern: X X X / . X . / . X . . That is a T shape pointing up. So R -> T shape pointing up.

Example 3: Input 5x5 with G scattered. Output pattern: . . X / . . X / X X X. That is a T shape pointing down. So G -> T shape pointing down.

Thus mapping: B -> plus, R -> T up, G -> T down.

Now test input is G. So output should be T shape pointing down: bottom row all X, center column X's above. So output grid:

Row1: . . X
Row2: . . X
Row3: X X X

But we need to confirm that the output grid uses X for grey and . for black. Yes.

Now we need to produce the output grid in the required format: each row on a new line, characters separated by spaces. So we need to output:

. . X
. . X
X X X

But we need to check if there is any nuance: The output grid is 3x3. The training examples show that the output grid is always 3x3. So we output 3 rows of 3 characters each.

But we need to double-check that the mapping is indeed correct. Let's analyze the input patterns to see if there is any other rule that might produce the output pattern. For example, maybe the output pattern is derived from the positions of the color cells in the input grid. But the output pattern is always the same shape for each color, regardless of the arrangement of the color cells. Let's test that: In Example 1, the B cells are scattered in various positions. The output pattern is plus shape. In Example 2, the R cells are scatte

We need to solve a grid transformation puzzle. We have training examples. Input is 5x5 grid with one colored front scattered. Output is 3x3 pressure signature in grey, fixed per front type. The metaphor: "weather map with scattered storm cells all tinted in one front's characteristic color. Read the color of the front and draw its invariant pressure signature — a small fixed pattern the atmosphere always stamps down for that front type." So we need to map the color of the front to a fixed 3x3 pattern of grey X's and dots? The output examples show patterns of X and . (grey and black). The output is 3x3. The pattern depends on the color of the front. The input has a single color (B, R, G). The output pattern is fixed per color. So we need to deduce mapping from color to pattern.

We have three training examples:

Example 1: Input color B (blue). Output pattern:
. X .
X X X
. X .

Example 2: Input color R (red). Output pattern:
X X X
. X .
. X .

Example 3: Input color G (green). Output pattern:
. . X
. . X
X X X

So we have mapping:

Blue -> pattern1
Red -> pattern2
Green -> pattern3

We need to produce output for test input: color G. So we need to output pattern3. But we must confirm that the test input is indeed green. Let's check test input:

Test Input:
. G . G G
. . G . .
G . . . .
. . G . G
. . . . G

Yes, all colored cells are G. So the front color is green. So we need to output the pattern for green: pattern3.

But we need to confirm that the pattern is indeed fixed per color. Let's analyze the training examples to confirm.

Example 1: Input grid 5x5 with B cells scattered. Output pattern: . X . / X X X / . X . . That is a cross shape with center X and arms. Actually pattern: row1: . X . ; row2: X X X ; row3: . X . . Wait row3 has 3 columns: . X . . Wait output is 3x3, so row3: . X . . Wait that would be 4 columns. Let's check the output formatting: Example 1 Output:
. X .
X X X
. X .

So row1: . X . (3 columns)
row2: X X X (3 columns)
row3: . X . (3 columns)
Yes, correct.

Example 2 Output:
X X X
. X .
. X .

So row1: X X X
row2: . X .
row3: . X .

Example 3 Output:
. . X
. . X
X X X

So row1: . . X
row2: . . X
row3: X X X

So indeed each color maps to a unique 3x3 pattern.

Thus for test input color G, we output pattern3: . . X / . . X / X X X.

But we need to double-check that the mapping is indeed color-specific and not something else like orientation or shape of input. But the puzzle says "Read the color of the front and draw its invariant pressure signature — a small fixed pattern the atmosphere always stamps down for that front type." So yes, the output is fixed per color.

Thus we just output the pattern for green.

But we should confirm that the pattern for green is indeed . . X / . . X / X X X. Let's double-check training example 3: Input grid 5x5 with G cells. Output pattern: . . X / . . X / X X X. Yes.

Thus answer: 3x3 grid:

. . X
. . X
X X X

We need to output with spaces between characters? The instruction: "write the complete predicted output grid using these single-character color codes: Color key: .=black B=blue R=red G=green Y=yellow X=grey M=magenta O=orange A=azure W=maroon. At the very end of your response, write the complete output grid inside a clearly labeled block like this: ANSWER: . B R G Y ."

So we need to output:

ANSWER:
. . X
. . X
X X X

But we need to ensure formatting: each row on a new line, characters separated by spaces. So:

ANSWER:
. . X
. . X
X X X

Yes.

But we should also consider if there might be any other transformation rule that could produce the same patterns. Let's analyze the input patterns to see if there's any other mapping.

Example 1: Input B cells scattered. Output pattern: cross shape. Example 2: Input R cells scattered. Output pattern: vertical line on right side? Actually pattern: X X X / . X . / . X . . That is a shape like a rotated cross? Let's analyze.

Example 1 pattern: cross shape: center X, arms up, down, left, right. Example 2 pattern: shape like a diagonal? Let's draw:

Row1: X X X
Row2: . X .
Row3: . X .

So shape: top row all X, then a vertical line on right side? Actually row2: . X . (X in middle). Row3: . X . (X in middle). So shape: a vertical line in middle column, plus top row all X. So shape like a T rotated? Actually it's like a T shape with top horizontal line and vertical line down from center. But the vertical line is in middle column, not right side. So shape: a T shape oriented with top horizontal line and vertical line down from center. Example 3 pattern: . . X / . . X / X X X. That is a shape like a rotated T? Let's see: top row: . . X (X in rightmost column). Row2: . . X (X in rightmost column). Row3: X X X (bottom row all X). So shape: a T shape rotated 180 degrees? Actually it's like a T shape with bottom horizontal line and vertical line up from rightmost column. So pattern: a T shape rotated 180 degrees relative to example 2? Let's compare: Example 2: top horizontal line, vertical line down

We need to solve a grid transformation puzzle. We have training examples: Input 5x5 grid with one colored brick type (like B, R, G). Output is 3x3 grid with X's and . (grey and black). The description: "Rubble of one type of glazed brick scattered across a dark foundation. Identify the glaze color and carve the keystone pattern that clay was always meant to form. Input: 5x5 foundation with one colored brick type. Output: 3x3 keystone pattern in grey, determined by glaze."

So we need to find a rule mapping 5x5 grid with one colored brick type to a 3x3 pattern of X's and . (grey and black). The colored bricks are scattered across the 5x5 grid. The output is a 3x3 pattern of X's and . that seems to be derived from the arrangement of the colored bricks. The output pattern is always 3x3. The X's represent grey, . represent black. The pattern seems to be a "keystone pattern" carved from the arrangement of the colored bricks.

We need to analyze the training examples to deduce the rule.

We have 6 training examples. Let's list them.

We need to solve a grid transformation puzzle. We have training examples. We need to deduce the rule. Let's analyze.

We have a 5x5 input grid with colored cells (B, R, G). Output is a 3x3 grid with X's and dots. The rule: "Identify the kingdom by banner color and deploy its predetermined siege formation — a compact tactical shape." So each color corresponds to a fixed 3x3 pattern of X's and dots. The input grid has one colored force (one color). The output is the 3x3 shape for that color. The shape is fixed per color. So we need to map each color to a 3x3 pattern.

We have training examples for B, R, G. We need to deduce the patterns.

Example 1: Input has B cells. Output is:

. X .
X X X
. X .

So pattern for B is:

Row1: . X .
Row2: X X X
Row3: . X .

Example 2: Input has R cells. Output:

X X X
. X .
. X .

So pattern for R is:

Row1: X X X
Row2: . X .
Row3: . X .

Example 3: Input has G cells. Output:

. . X
. . X
X X X

So pattern for G is:

Row1: . . X
Row2: . . X
Row3: X X X

Thus we have patterns for B, R, G. The test input has G cells. So output should be the pattern for G: . . X / . . X / X X X.

But we need to confirm that the pattern is indeed fixed per color. Let's double-check.

Example 1: Input grid 5x5 with B cells. Output pattern matches B pattern. Example 2: R pattern matches. Example 3: G pattern matches. So yes.

Now test input: 5x5 grid with G cells. Output should be G pattern.

But we need to confirm that the test input indeed has only G cells. Let's examine test input:

. G . G G
. . G . .
G . . . .
. . G . G
. . . . G

Yes, all colored cells are G. So output should be G pattern.

Thus answer:

. . X
. . X
X X X

But we need to output with spaces between characters? The instruction: "write the complete output grid inside a clearly labeled block like this: ANSWER: . B R G Y .". They show each row on a new line, characters separated by spaces. So we need to output:

ANSWER:
. . X
. . X
X X X

But we need to ensure we use spaces between characters. So:

ANSWER:
. . X
. . X
X X X

Yes.

But let's double-check the pattern orientation. Are we sure the pattern orientation is correct? Let's examine the training examples to confirm orientation.

Example 1: Input B pattern. Output:

. X .
X X X
. X .

Let's see if that matches some known shape. It looks like a cross shape rotated? Actually it's like a plus shape but missing top-left and top-right? Wait, let's draw:

Row1: . X .
Row2: X X X
Row3: . X .

This is like a plus shape with center and arms left, right, and down? Actually plus shape would be:

. X .
X X X
. X .

Yes, that's a plus shape with center and arms left, right, and down. But missing up? Wait, plus shape would have up arm too: . X . ; X X X ; . X . ; Actually plus shape has arms up, left, right, down. But here we have arms left, right, down, but not up. So it's like a T shape rotated? Let's analyze: The shape is like a T rotated 90 degrees? Actually T shape would be:

X X X
. X .
. X .

But here we have:

. X .
X X X
. X .

That's like a T shape rotated 180 degrees? Wait, T shape rotated 180 degrees would be:

. X .
X X X
. X .

Yes, that's exactly the shape. So B pattern is a T shape rotated 180 degrees (pointing downwards). Actually T shape rotated 180 degrees would have the top horizontal bar at the bottom row, and the vertical bar at the center of the top row. So yes.

Example 2: R pattern:

X X X
. X .
. X .

This is a T shape pointing up (vertical bar at center of bottom row). Actually T shape pointing up would be:

. X .
X X X
. X .

Wait, no. Let's think: T shape pointing up: vertical bar at center of bottom row? Actually T shape pointing up: the horizontal bar at top row, vertical bar at center of bottom row? Let's draw:

Row1: X X X
Row2: . X .
Row3: . X .

This shape has horizontal bar at top row, vertical bar at center of bottom two rows. So it's like a T shape pointing down? Wait, T shape pointing down would have horizontal bar at bottom row, vertical bar at center of top two rows. But here horizontal bar at top row, vertical bar at center of bottom two rows. That is a T shape pointing up? Let's think: If you rotate a T shape 180 degrees, you get horizontal bar at bottom row, vertical bar at center of top two rows. But here horizontal bar at top row, vertical bar at center of bottom two rows. That is a T shape rotated 90 degrees? Actually T shape rotated 90 degrees clockwise would have horizontal bar at left column? Let's not get lost. The shape is symmetrical: horizontal bar at top row, vertical bar at center of bottom two rows. So it's like a T shape rotated 90 degrees? Let's just accept that each color has a unique shape.

Example 3: G pattern:

. . X
. . X
X X X

This shape is like a T shape rotated 270 degrees? Actually horizontal bar at bottom row, vertical bar at center of right column. So it's like a T shape rotated 270 degrees (pointing left). Wait, let's analyze: The shape has horizontal bar at bottom row, vertical bar at center of right column. So

We need to solve a grid transformation puzzle. We have training examples: Example 1, 2, 3. Input grids are 5x5, output grids are 3x3. The transformation seems to involve selecting a particular color (mask color) and producing a 3x3 pattern of X's and . (black). The description: "Performers in identical colored masks milling about a dark backstage. Note the mask color and reveal the troupe's eternal tableau — one frozen pose per company, regardless of where they stood in the wings. Input: 5x5 backstage with one mask color scattered. Output: 3x3 tableau in grey, unique per troupe." So we need to find the rule: For each input grid, we have a color (B, R, G). The output grid is 3x3 with X's and . (black). The output pattern seems to be unique per color. The description says "one frozen pose per company, regardless of where they stood in the wings." So maybe the output pattern is a fixed 3x3 pattern for each color, independent of the arrangement of that color in the input. But the examples show that the output pattern is the same for each color? Let's check.

Example 1: Input has B's scattered. Output is:
. X .
X X X
. X .

Example 2: Input has R's scattered. Output is:
X X X
. X .
. X .

Example 3: Input has G's scattered. Output is:
. . X
. . X
X X X

So each color has a unique 3x3 pattern. The pattern is not the same across colors. So the rule: For each color, produce a fixed 3x3 pattern of X's and . (black). The pattern is predetermined. The puzzle is to deduce the mapping from color to pattern. The test input is G. So we need to produce the pattern for G. But we already have the pattern for G from Example 3. So the answer should be the same as Example 3's output: 
. . X
. . X
X X X

But we need to confirm that the pattern for G is indeed that. Let's double-check the mapping: Example 3 input is G. Output is . . X / . . X / X X X. So yes. So the test input is also G. So the output should be the same pattern. But we need to confirm that the mapping is indeed color-specific and not dependent on arrangement. The description says "one frozen pose per company, regardless of where they stood in the wings." That implies that the output pattern is independent of the arrangement of the color in the input. So we can produce the same pattern for G. So the answer is:

. . X
. . X
X X X

But we need to output with spaces between characters? The instructions: "write the complete predicted output grid using these single-character color codes: Color key: .=black B=blue R=red G=green Y=yellow X=grey M=magenta O=orange A=azure W=maroon. At the very end of your response, write the complete output grid inside a clearly labeled block like this: ANSWER: . B R G Y ."

So we need to produce:

ANSWER:
. . X
. . X
X X X

But we need to separate characters by spaces? The example shows "ANSWER: . B R G Y .". That is a single line with spaces. But the block example shows each row on a new line, characters separated by spaces. The instruction: "one row per line, characters separated by spaces". So we need to produce:

ANSWER:
. . X
. . X
X X X

But we need to ensure each row is on a new line, and each character separated by a space. So we need to produce:

ANSWER:
. . X
. . X
X X X

Yes.

But we need to double-check that the mapping is indeed color-specific. Let's analyze the training examples more thoroughly to confirm.

Example 1: Input 5x5 with B's. Output 3x3 pattern: . X . / X X X / . X . . This pattern is symmetrical horizontally? Let's see: Row1: . X . ; Row2: X X X ; Row3: . X . . This is a cross shape: center column X, center row X. So it's like a plus sign. Example 2: Input R's. Output: X X X / . X . / . X . . This pattern is like a diagonal? Let's see: Row1: X X X ; Row2: . X . ; Row3: . X . . This is like a vertical line on the right? Actually row1 all X, row2 X in center, row3 X in center. So it's like a vertical line in the center column, but also top row all X. So it's like a T shape? Wait, row1 all X, row2 center X, row3 center X. So it's like a vertical line in center column, plus a horizontal line at top row. So it's like a T shape rotated? Actually a T shape would be top row all X, center column X. Yes, that's exactly a T shape. So Example 2 output is a T shape. Example 3: Input G's. Output: . . X / . . X / X X X. This is like a rotated T shape? Let's see: Row1: . . X ; Row2: . . X ; Row3: X X X. So it's like a vertical line on the right column, plus a horizontal line at bottom row. So it's like a T shape rotated 90 degrees clockwise. So each color has a unique orientation of a T shape? Let's check: Example 1: B's output is a plus shape. Example 2: R's output is a T shape. Example 3: G's output is a rotated T shape. So maybe the mapping is: B -> plus shape; R -> T shape; G -> rotated T shape. But we need to confirm if there are other colors in the puzzle? The color key includes B, R, G, Y, X, M, O, A, W. But we only have B, R, G in training. The test input is G. So we can produce the pattern for G. But we

We need to solve a grid transformation puzzle. We have training examples: Example 1, 2, 3. Input grids are 5x5, output grids are 3x3. The transformation seems to involve identifying a "seed" color and constructing a "trellis" pattern in grey (X). The output is a 3x3 grid of X and . (black). The pattern seems to be fixed per species (seed color). So each color has a unique 3x3 pattern of X and . (maybe representing a shape). The input grid contains one seed color (like B, R, G). The output is the 3x3 pattern for that color. The pattern is fixed per species, not dependent on the arrangement of seeds in the input. So we need to deduce the mapping from color to 3x3 pattern.

We have three training examples:

Example 1: Input has B seeds. Output is:

. X .
X X X
. X .

So for B, the pattern is:

Row1: . X .
Row2: X X X
Row3: . X .

Example 2: Input has R seeds. Output is:

X X X
. X .
. X .

So for R, pattern:

Row1: X X X
Row2: . X .
Row3: . X .

Example 3: Input has G seeds. Output is:

. . X
. . X
X X X

So for G, pattern:

Row1: . . X
Row2: . . X
Row3: X X X

Now test input: . G . G G
. . G . .
G . . . .
. . G . G
. . . . G

So the seed color is G. So we need to output the pattern for G: . . X / . . X / X X X. That is the 3x3 grid.

But we need to double-check: Are there any other colors? The test input only has G seeds. So we output the G pattern.

But we need to confirm that the mapping is indeed fixed per species. Let's analyze the training examples more thoroughly to ensure no other nuance.

We have 5x5 input grids. They contain a single color (B, R, G). The output is a 3x3 grid of X and . . The pattern seems to be a shape of X's that might correspond to a "trellis" shape for each species. The shape might be a rotated or mirrored version of something. Let's examine each pattern:

B pattern:

. X .
X X X
. X .

This is a cross shape: a plus sign shape. The center is X, plus arms up, down, left, right. Actually the pattern is a plus shape: center X, arms up, down, left, right. But the pattern shows X at center (row2 col2), X at row2 col1, row2 col3, row1 col2, row3 col2. So yes, a plus shape.

R pattern:

X X X
. X .
. X .

This is like a vertical line of X's at column 2 (center column) from row1 to row3, plus a horizontal line at row1 from col1 to col3. So shape: top row all X, middle row center X, bottom row center X. So shape like a T rotated? Actually it's like a T shape but with the top horizontal line and vertical line down from center. So shape: a T shape pointing downwards? Wait, a T shape pointing downwards would have top horizontal line and vertical line down from center. Yes, that's exactly the shape: a T shape pointing downwards. So R pattern is a T shape pointing downwards.

G pattern:

. . X
. . X
X X X

This is like a T shape pointing upwards? Actually it's a T shape pointing upwards: bottom horizontal line of X's across row3, vertical line up from center at column3. So shape: a T shape pointing upwards. So G pattern is a T shape pointing upwards.

Thus the patterns correspond to shapes: B is a plus shape, R is a T shape pointing downwards, G is a T shape pointing upwards. So each species has a unique shape.

Now test input: G seeds. So output should be the G pattern: . . X / . . X / X X X.

But we need to confirm that the output grid uses X for grey and . for black. Yes, the output uses X for grey. So we output the pattern.

But we need to check if there is any nuance about orientation or rotation. The pattern for G is . . X / . . X / X X X. That matches the training example 3. So we output that.

But we need to double-check that the test input indeed has G seeds. The test input grid:

Row1: . G . G G
Row2: . . G . .
Row3: G . . . .
Row4: . . G . G
Row5: . . . . G

Yes, G appears in many positions. So the seed color is G. So output is G pattern.

Thus the answer is:

. . X
. . X
X X X

But we need to output in the format: each row on a new line, characters separated by spaces? The instructions: "At the very end of your response, write the complete output grid inside a clearly labeled block like this: ANSWER: . B R G Y .". Actually the example shows:

ANSWER:
. B R
G Y .

But that example uses spaces between characters. The instructions: "write the complete output grid inside a clearly labeled block like this: ANSWER: . B R G Y . (one row per line, characters separated by spaces)". So we need to output the grid with spaces between characters. So we need to output:

ANSWER:
. . X
. . X
X X X

But we need to ensure we separate each character by a space. So we need to output:

ANSWER:
. . X
. . X
X X X

But we need to check if we need to include spaces between each character. The example shows "ANSWER: . B R G Y .". Actually the example shows "ANSWER: . B R G Y .". Wait, the example shows:

ANSWER:
. B R
G Y .

So each row is separated by newline, and each character separated by space. So we need to output:

ANSWER:
. . X
. . X
X X X

Yes.

But we need to double-check if the output grid is 3x3.

We need to parse the puzzle. The description: "grid transformation puzzle" with metaphorical description. We have training example 1: Input grid 10x3? Wait: Example 1 Input: 10 rows of 3 columns? Let's examine:

Input:
. . .
. . .
. . .
. . .
. . .
. . .
. . .
. . .
. . .
B . .

So 10 rows, 3 columns. The bottom row has B . .? Wait bottom row: "B . ." but there are only 3 columns. Actually bottom row: "B . ." means B in first column, dot in second, dot in third. So bottom-left corner has B. The rest are dots.

Output: 10 rows of 3 columns:

A B A
B A A
A B A
A A B
A B A
B A A
A B A
A A B
A B A
B A A

So output is 10x3 grid with A and B. The pattern seems like a zigzag of B's along a diagonal? Let's analyze.

We have 10 rows, 3 columns. Let's index rows from top (row0) to bottom (row9). Input: B at row9 col0. Output: Let's list coordinates of B's:

Row0: A B A -> B at col1
Row1: B A A -> B at col0
Row2: A B A -> B at col1
Row3: A A B -> B at col2
Row4: A B A -> B at col1
Row5: B A A -> B at col0
Row6: A B A -> B at col1
Row7: A A B -> B at col2
Row8: A B A -> B at col1
Row9: B A A -> B at col0

So B's positions: (row0,1), (1,0), (2,1), (3,2), (4,1), (5,0), (6,1), (7,2), (8,1), (9,0). This is a zigzag path starting at bottom-left (row9,0). It moves upward and rightwards, bouncing off walls. The pattern: Starting at bottom-left, go up one row and right one column: row8 col1. Then up one row and right one column: row7 col2. Then up one row and right one column: row6 col3? But there is no col3; so bounce off right wall: go left instead: row6 col1? Wait we need to analyze.

Let's simulate: Starting at (9,0). Move up one row, right one column: (8,1). Good. Next: up one row, right one column: (7,2). Good. Next: up one row, right one column: would be (6,3) but col3 out of bounds (max col2). So bounce: reflect direction horizontally: now direction becomes leftwards? Actually bounce off right wall: direction changes from right to left. So next step: up one row, left one column: (6,1). Good. Next: up one row, left one column: (5,0). Good. Next: up one row, left one column: would be (4,-1) out of bounds left wall. Bounce: direction changes to right. So next: up one row, right one column: (4,1). Good. Next: up one row, right one column: (3,2). Good. Next: up one row, right one column: would be (2,3) out of bounds. Bounce: direction left. So next: up one row, left one column: (2,1). Good. Next: up one row, left one column: (1,0). Good. Next: up one row, left one column: would be (0,-1) out of bounds. Bounce: direction right. So next: up one row, right one column: (0,1). Good. That matches the output B positions. So indeed the rule is: Starting from bottom-left corner (row last, col 0) with a blue ball. The ball moves upward one row per step, and horizontally one column per step, bouncing off left/right walls. It leaves a blue mark on each floor (row) it passes through. The output grid has blue marks at those positions. The rest of the grid is filled with azure (A). The azure light fills every tile except where the ball has bounced — those tiles stay blue. Wait: The description says: "The azure light fills every tile except where the ball has bounced — those tiles stay blue." But the output shows azure (A) everywhere else. So azure is A. Blue is B. So the rule: Starting from bottom-left corner, ball moves upward one row per step, horizontally one column per step, bouncing off left/right walls. It leaves a blue mark on each floor it passes through. The rest of the grid is azure.

But the output also has azure at all other positions. So the transformation: Input grid has only a blue ball at bottom-left. Output grid has azure everywhere else, and blue marks along the path.

But the input grid also had only dots except bottom-left B. So the input basically indicates the starting position of the ball. The output is the path.

Now we need to apply to test input: 10 rows, 5 columns? Let's check test input:

Test Input:
. . . . .
. . . . .
. . . . .
. . . . .
. . . . .
. . . . .
. . . . .
. . . . .
. . . . .
B . . . .

So 10 rows, 5 columns. Bottom-left corner has B. So we need to produce output grid 10x5 with azure (A) everywhere else, and blue marks along the path.

We need to compute the path: Starting at bottom-left (row9, col0). Move upward one row per step, horizontally one column per step, bouncing off left/right walls. The grid width is 5 columns: indices 0-4. So we need to simulate until we reach the top row (row0). The ball will bounce off walls as needed. We need to produce a path of 10 positions (one per row). Because there are 10 rows, we will have 10 blue marks, one per row. The ball starts at row9 col0. Then row8 col1, row7 col2, row6 col3, row5 col4, row4 col3, row3 col2, row2 col1, row1 col0, row0 col1? Wait let's simulate carefully.

We need to simulate 10 steps (including starting position). Starting at row9 col0. Then for each step, we move up one row and horizontally o

We need to solve a grid transformation puzzle. We have a metaphorical description, training examples, and a test input grid. We need to produce the output grid.

We have a single training example: Input grid of 10 rows by 3 columns? Wait, the example shows Input: 10 rows of ". . ." (three columns) repeated 9 times, then last row "B . .". Actually the input grid is 10 rows, each row has 3 columns. The first 9 rows are all ". . .". The 10th row is "B . .". So the input grid is 10x3. The output grid is 10 rows of 3 columns each, with pattern of A and B. Let's examine the output:

Output:
A B A
B A A
A B A
A A B
A B A
B A A
A B A
A A B
A B A
B A A

So output grid is 10x3. The pattern seems to be a repeating pattern of A and B. Let's analyze.

We need to deduce the transformation rule. The metaphorical description: "What you see: A dark void of black space with a single blue comet at the lower-left edge. What to do: The comet drifts upward, pulled diagonally toward one star, then slung back toward the other when it nears the boundary. The void fills with azure cosmic dust from its tail, while the comet's blue nucleus occupies one position per row. Grid details: Same void dimensions. Azure dust background, one blue comet per row."

So the input: a dark void (black) with a single blue comet at the lower-left edge. That matches: 10x3 grid, all black except a blue at bottom-left (row 10, column 1). The output: azure dust background (so all cells become azure 'A' except the blue comet positions). The comet's blue nucleus occupies one position per row. So each row has a blue cell. The comet drifts upward, pulled diagonally toward one star, then slung back toward the other when it nears the boundary. So the blue comet moves diagonally upward across the grid, maybe bouncing off boundaries. The azure dust background fills the rest. So the output shows azure 'A' in all cells except the blue 'B' positions. The pattern of B's: Let's list coordinates of B in output. Coordinates: (row, col). Row 1: B at col 2. Row 2: B at col 1. Row 3: B at col 2. Row 4: B at col 3. Row 5: B at col 2. Row 6: B at col 1. Row 7: B at col 2. Row 8: B at col 3. Row 9: B at col 2. Row 10: B at col 1.

So the B positions: 1:2, 2:1, 3:2, 4:3, 5:2, 6:1, 7:2, 8:3, 9:2, 10:1. This looks like a pattern: The comet moves diagonally upward to the right until it hits the right boundary, then it bounces back to the left, etc. Let's analyze: Starting at bottom-left (row 10, col 1). Then moving upward diagonally to the right: row 9, col 2. Then row 8, col 3. Then row 7, col 4? But there is no col 4; grid width is 3. So at row 8, col 3 is the rightmost column. Next step would be row 7, col 4, but that's out of bounds. So the comet bounces back to the left: row 7, col 2? Wait, the pattern shows row 7, col 2. So after hitting right boundary at row 8, col 3, the next step is row 7, col 2. Then row 6, col 1. Then row 5, col 2. Then row 4, col 3. Then row 3, col 2. Then row 2, col 1. Then row 1, col 2. So indeed the comet moves diagonally upward, bouncing off boundaries. The pattern is like a zigzag path across the grid. The azure dust background fills all other cells.

Thus the transformation rule: For a grid of size HxW, with a single blue cell at bottom-left (row H, col 1). The output grid has azure 'A' in all cells except the blue comet positions. The blue comet moves upward diagonally, bouncing off left and right boundaries. The comet occupies one cell per row. So the output will have a blue cell in each row, following a zigzag path starting from bottom-left, moving up-right until hitting right boundary, then up-left until hitting left boundary, etc. The azure dust background fills the rest.

Now we need to apply this rule to the test input. The test input is:

. . . . .
. . . . .
. . . . .
. . . . .
. . . . .
. . . . .
. . . . .
. . . . .
. . . . .
B . . . .

So it's a 10x5 grid. The bottom-left cell is B at row 10, col 1. The rest are black '.'.

We need to produce output: azure dust background 'A' in all cells except the blue comet positions. The comet moves upward diagonally, bouncing off boundaries. The grid width is 5. So we need to compute the path of the comet across 10 rows.

Let's define coordinates: rows 1 to 10 from top to bottom. Starting at row 10, col 1. Then row 9, col 2. Row 8, col 3. Row 7, col 4. Row 6, col 5. Row 5, col 6? But col 6 is out of bounds (max col 5). So at row 6, col 5 is the rightmost column. Next step would be row 5, col 6, but out of bounds. So bounce: row 5, col 4. Then row 4, col 3. Row 3, col 2. Row 2, col 1. Row 1, col 2? Wait, we need to continue until we have a blue cell in each row. Let's compute step by step.

We have 10 rows. Starting at row 10: col 1. Then row 9: col 2. Row 8: col 3. Row 7: col 4. Row 6: col 5. Row 5: col 4 (bounce). Row 4: col 3. Row 3: col 2. Row 2: col 1. Row 1: col 2? Wait, after row 2: col 1, next step would be row 1: col 0? But col 0 is out of bounds. So bounce again: row 1: col 2? Let's think:

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A dark channel of black water with a blue-hulled vessel anchored at the bottom-left. What to do: The ship sails upward, tacking diagonally toward one shore then turning about to angle toward the other. The water lightens to azure with the morning tide, while the blue ship occupies a single cell in each row of the channel. Grid details: Same channel dimensions. Azure water throughout, one blue hull per row."

We have training examples. Example 1: Input grid 10x3? Wait let's parse.

Example 1 Input: 
```
. . .
. . .
. . .
. . .
. . .
. . .
. . .
. . .
. . .
. . .
B . .
```
So 10 rows, 3 columns? Actually the input shows 10 rows of 3 columns each? Let's count: The first 9 rows are ". . ." (three columns). The 10th row is "B . ." (three columns). So yes, 10 rows, 3 columns. The output grid is:

```
A B A
B A A
A B A
A A B
A B A
B A A
A B A
A A B
A B A
B A A
```

So output is also 10 rows, 3 columns. The output pattern seems to be a checkerboard pattern of A and B, but with some shift? Let's analyze.

Row 1: A B A
Row 2: B A A
Row 3: A B A
Row 4: A A B
Row 5: A B A
Row 6: B A A
Row 7: A B A
Row 8: A A B
Row 9: A B A
Row 10: B A A

This pattern seems to be repeating every 3 rows? Let's examine the pattern of A and B. Let's write coordinates: (row, col). Let's mark B positions.

Row1: col2
Row2: col1
Row3: col2
Row4: col3
Row5: col2
Row6: col1
Row7: col2
Row8: col3
Row9: col2
Row10: col1

So B positions: (1,2), (2,1), (3,2), (4,3), (5,2), (6,1), (7,2), (8,3), (9,2), (10,1). This looks like a diagonal pattern: B moves down-left each time? Let's see: Starting at (1,2). Next B at (2,1) is down-left. Next B at (3,2) is down-right. Next B at (4,3) is down-right again? Wait from (3,2) to (4,3) is down-right. Then (5,2) is down-left. Then (6,1) down-left. Then (7,2) down-right. Then (8,3) down-right. Then (9,2) down-left. Then (10,1) down-left. So pattern: down-left, down-right, down-right, down-left, down-left, down-right, down-right, down-left, down-left. That seems like a zigzag pattern: The B moves diagonally across the grid, bouncing off the left and right boundaries. The pattern might be a "tacking" path: The ship moves diagonally up (but here downwards because input orientation maybe reversed). The ship starts at bottom-left (row 10, col1). In input, B is at bottom-left. In output, B appears in each row, one per row, forming a zigzag path that goes up-left to up-right? Wait orientation: The input shows B at bottom-left. The output shows B in each row, forming a zigzag path that goes up-right? Let's examine: In output, B positions: row1 col2, row2 col1, row3 col2, row4 col3, row5 col2, row6 col1, row7 col2, row8 col3, row9 col2, row10 col1. So if we imagine the grid with row1 at top, row10 at bottom, B moves from bottom-left (row10 col1) up-right to row9 col2, up-left to row8 col1? Wait row9 col2 is up-left? Actually from row10 col1 to row9 col2 is up-right (row decreases, col increases). Then row8 col3 is up-right again. Then row7 col2 is up-left. Then row6 col1 is up-left. Then row5 col2 is up-right. Then row4 col3 is up-right. Then row3 col2 is up-left. Then row2 col1 is up-left. Then row1 col2 is up-right. So the B moves up-right, up-right, up-left, up-left, up-right, up-right, up-left, up-left, up-right. So it's a zigzag path that alternates between two directions: up-right and up-left. The pattern seems to be: start at bottom-left, go up-right until hitting the right boundary, then bounce to up-left until hitting left boundary, etc. But the pattern in output shows B at each row, so the ship occupies a single cell in each row. The path is a zigzag across the grid.

Now Example 2: Input: 10 rows, 2 columns. Input grid:

```
. .
. .
. .
. .
. .
. .
. .
. .
. .
B .
```

So 10 rows, 2 columns. B at bottom-left (row10 col1). Output:

```
A B
B A
A B
B A
A B
B A
A B
B A
A B
B A
```

So output is 10 rows, 2 columns. B positions: row1 col2, row2 col1, row3 col2, row4 col1, row5 col2, row6 col1, row7 col2, row8 col1, row9 col2, row10 col1. So B moves up-right, up-left, up-right, up-left, etc. So it's a zigzag path that alternates each row. Since there are only 2 columns, the ship moves up-right to the right boundary, then up-left to left boundary, etc. So the pattern is consistent.

Thus the transformation rule: The input grid is all black cells (.) except a single B at bottom-left. The output grid is all azure cells (A) except a B in each row, following a zigzag path that starts at bottom-left and moves up-right until hitting the right boundary, then up-left until hitting the left boundary, etc. The azure water is the background. The B occupies a single cell in each row, forming a zigzag path.

We need to solve a grid transformation puzzle. We have a metaphorical description, training examples, and a test input grid. We need to produce the output grid.

We have to parse the puzzle: The description: "What you see: A dark obsidian corridor with a single blue divine spark at the bottom-left threshold. What to do: The messenger god springs upward, his path angling between the narrow corridor walls, reversing at each side. His passage awakens the stone to glowing azure, while his blue sandal-print marks one tile per level. Grid details: Same corridor dimensions. Azure awakened stone, one blue footprint per row."

We have a color key: .=black B=blue R=red G=green Y=yellow X=grey M=magenta O=orange A=azure W=maroon

We need to produce output grid.

We need to analyze the transformation rule.

Observations: In training examples, input grid is all black except a single B at bottom-left corner (row 10, column 1 for 10x3 grid in example 1; row 10, column 1 for 10x2 grid in example 2). Output grid is a pattern of A and B. The pattern seems to be a checkerboard pattern but with a twist: The B's in the output are arranged in a diagonal pattern? Let's examine.

Example 1: Input grid 10 rows x 3 columns. Output grid 10 rows x 3 columns. Let's write them:

Row1: A B A
Row2: B A A
Row3: A B A
Row4: A A B
Row5: A B A
Row6: B A A
Row7: A B A
Row8: A A B
Row9: A B A
Row10: B A A

We can see that the pattern is like a repeating pattern of 3 columns: maybe a 3x3 repeating pattern? Let's examine the pattern of B's: In each row, there is exactly one B? Let's check: Row1 has B at column2. Row2 has B at column1. Row3 has B at column2. Row4 has B at column3. Row5 has B at column2. Row6 has B at column1. Row7 has B at column2. Row8 has B at column3. Row9 has B at column2. Row10 has B at column1. So each row has exactly one B. So the output grid has exactly one B per row. The B's are arranged in a pattern that seems to cycle: 2,1,2,3,2,1,2,3,2,1. So the B column index cycles through 2,1,2,3,2,1,2,3,2,1. That is a repeating pattern of length 4? Let's see: 2,1,2,3,2,1,2,3,2,1. The pattern of 4: 2,1,2,3. Then repeats: 2,1,2,3. Then 2,1. So yes, the pattern of 4 repeats: 2,1,2,3. So the B column index cycles through 2,1,2,3. That is a pattern of length 4. So the B's move left-right-left-right? Actually, the pattern is: start at column2, then column1, then column2, then column3, then column2, then column1, etc. So it's like a bouncing pattern: The B moves left to right, bouncing off the walls. Starting at column2, then moves left to column1, then right to column2, then right to column3, then left to column2, then left to column1, etc. So it's like a bouncing ball moving horizontally across the corridor of width 3. The B's are placed at each row, one per row, following the bouncing path. The B's start at column2? Wait, the input had a B at bottom-left threshold (row10, column1). But the output B's start at column2? Let's check: The input B is at bottom-left threshold. The output B's are at row10 column1. So the bottom row B is at column1. That matches the input B. So the B's in the output follow a path that starts at the bottom-left threshold and moves upward, bouncing off walls. The B's are placed at each row along the path. So the B's in the output are the path of the messenger god moving upward, bouncing off walls. The B's are the blue footprints. The rest of the cells are azure (A). So the output grid is all A except the B's along the path.

Now, let's check Example 2: Input grid 10 rows x 2 columns. Output grid 10 rows x 2 columns. Output:

Row1: A B
Row2: B A
Row3: A B
Row4: B A
Row5: A B
Row6: B A
Row7: A B
Row8: B A
Row9: A B
Row10: B A

So each row has one B. The B column index cycles: 2,1,2,1,2,1,2,1,2,1. So it's a bouncing pattern across 2 columns: start at column2, then column1, then column2, etc. The bottom row B is at column1, matching the input B at bottom-left threshold. So the pattern is consistent.

Thus, the transformation rule: The input grid is all black except a single B at bottom-left threshold (row N, column 1). The output grid is all A except a B at each row along a path that starts at the bottom-left threshold and moves upward, bouncing horizontally between the leftmost and rightmost columns. The B's are placed at each row along the path. The path is a zigzag: starting at column1 at bottom row, then moving up one row and one column to the right (if possible), then up one row and one column to the left, etc. But we need to confirm the direction: In Example 1, the B's start at bottom row column1. Then row9 B at co

We need to parse the puzzle. The description: "You are solving a grid transformation puzzle. You are given a metaphorical description of the transformation, training examples, and a test input grid.

## Metaphorical Description

What you see: A stack of pale crepe layers with a lone blueberry resting at the bottom-left corner.
What to do: The cake is gently rocked, and the blueberry rolls diagonally upward, reversing direction each time it hits the edge of the plate. Each layer it crosses is stained azure with butter glaze, while the berry leaves its blue mark at one position per layer.
Grid details: Same dimensions as the stack. Butter-glazed azure layers with one blueberry-blue mark per row.

Before predicting the output, perform a Conceptual Digestion:
1. Identify the CAST: What roles do different grid elements play?
2. Identify the AFFORDANCES: What can each element do or have done to it?
3. Identify the TRANSFORMATION RULE: What is the precise rule that maps input to output?

Then apply the rule to the test input to predict the output grid.

At the very end of your response, write the complete output grid inside a clearly labeled block like this:

We need to produce output grid for test input. We have only one training example. Let's analyze.

Input grid: 10 rows, 3 columns? Wait example 1 input: 10 rows of 3 columns? Let's count: Provided lines:

Input:
. . .
. . .
. . .
. . .
. . .
. . .
. . .
. . .
. . .
B . .

That's 10 rows, each with 3 columns. The last row has B . . (blue at first column). So input grid is 10x3. Output grid: 10 rows, 3 columns. Provided output:

A B A
B A A
A B A
A A B
A B A
B A A
A B A
A A B
A B A
B A A

So output grid is 10x3. So transformation: Input has a single B at bottom-left corner (row 10, col 1). Output has pattern of A and B across grid. Let's analyze pattern.

We need to deduce rule: "stack of pale crepe layers with a lone blueberry resting at the bottom-left corner. The cake is gently rocked, and the blueberry rolls diagonally upward, reversing direction each time it hits the edge of the plate. Each layer it crosses is stained azure with butter glaze, while the berry leaves its blue mark at one position per layer. Grid details: Same dimensions as the stack. Butter-glazed azure layers with one blueberry-blue mark per row."

Interpretation: The blueberry starts at bottom-left corner. It rolls diagonally upward (i.e., up-right direction). When it hits an edge, it reverses direction (like bouncing). Each layer it crosses is stained azure (A). The berry leaves a blue mark at one position per layer. So each row (layer) will have one B mark (blue). The rest of cells in that row are A (azure). But the output shows each row has exactly one B? Let's check: Output rows:

Row1: A B A -> B at col2
Row2: B A A -> B at col1
Row3: A B A -> B at col2
Row4: A A B -> B at col3
Row5: A B A -> B at col2
Row6: B A A -> B at col1
Row7: A B A -> B at col2
Row8: A A B -> B at col3
Row9: A B A -> B at col2
Row10: B A A -> B at col1

Yes each row has exactly one B. So rule: Starting from bottom-left, blueberry moves diagonally upward-right until it hits right edge, then reverses direction to up-left, etc. Each row visited by blueberry gets a B at that column. All other cells become A. That matches output.

Let's confirm pattern: Starting at bottom-left (row10, col1). Move up-right: row9, col2. Row8, col3. Row7, col4? But grid only 3 columns. So at row8, col3 is rightmost. Next step would be row7, col4 but col4 doesn't exist, so hits right edge. So it reverses direction: now moving up-left. So from row8, col3, next step row7, col2. Wait but output row7 has B at col2. Yes. Then row6, col1. Row5, col0? But col0 doesn't exist, so hits left edge. Reverse direction: now moving up-right again. So row5, col1? Wait we need to track carefully.

Let's simulate:

Grid 10x3. Coordinates: row index from bottom 1 to top 10? Let's define row 10 is top? Actually input row 10 is bottom? Wait input shows B at bottom-left. In input, B is at last row (row10). So row10 is bottom row. So row1 is top row. So we need to simulate from bottom row upward.

Let's index rows from bottom: row0 bottom? Let's just simulate.

Start at row10 (bottom), col1. Mark B at (10,1). Next step: up-right: row9, col2. Mark B at (9,2). Next: up-right: row8, col3. Mark B at (8,3). Next: up-right: ro

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A black court viewed from above, with a blue squash ball in the near-left corner. What to do: The ball is struck and travels forward, bouncing off the left and right side walls alternately. Each row of the court it crosses gets scuffed azure by shoe marks, while the ball itself leaves a single blue impact point per row. Grid details: Court dimensions unchanged. Azure floor with one blue bounce mark per row."

We have training examples. Example 1: Input grid 10x3? Wait let's parse.

Example 1 Input:
```
. . .
. . .
. . .
. . .
. . .
. . .
. . .
. . .
. . .
B . .
```
So 10 rows, 3 columns. The last row has B . .? Wait the last row is "B . ."? Actually the input shows 10 rows of 3 columns each. The last row is "B . .". So the ball B is at row 10, column 1 (near-left corner). The rest are all '.' (black). Output grid:
```
A B A
B A A
A B A
A A B
A B A
B A A
A B A
A A B
A B A
B A A
```
So output is 10 rows, 3 columns. The pattern is alternating A and B. Let's analyze.

The output grid has A's and B's. The ball B appears in the output at positions: row 1 col 2? Wait row 1: "A B A" -> B at col 2. Row 2: "B A A" -> B at col 1. Row 3: "A B A" -> B at col 2. Row 4: "A A B" -> B at col 3. Row 5: "A B A" -> B at col 2. Row 6: "B A A" -> B at col 1. Row 7: "A B A" -> B at col 2. Row 8: "A A B" -> B at col 3. Row 9: "A B A" -> B at col 2. Row 10: "B A A" -> B at col 1.

So the B's appear in a pattern: starting at row 1 col 2, then row 2 col 1, row 3 col 2, row 4 col 3, row 5 col 2, row 6 col 1, row 7 col 2, row 8 col 3, row 9 col 2, row 10 col 1. This looks like a ball bouncing left and right across the 3 columns. Starting at leftmost column? Wait the ball starts at row 10 col 1 (bottom left). The ball is struck and travels forward (upwards). It bounces off left and right side walls alternately. Each row it crosses gets scuffed azure by shoe marks, while the ball itself leaves a single blue impact point per row. So the ball travels upward, bouncing left and right. The ball leaves a blue mark at each row it passes. The floor gets scuffed azure (A) in each row it crosses. So the output grid should have azure marks in all cells except the ball's path? Wait the output shows A's and B's. The ball B appears at one cell per row. The rest of the cells in that row are A. So each row has one B and the rest A. That matches the description: each row gets scuffed azure (A) by shoe marks, while the ball itself leaves a single blue impact point per row. So the ball's path is a single B per row. The ball starts at bottom left (row 10 col 1). It travels upward, bouncing left and right. The ball's path across rows: row 10 col 1, row 9 col 2, row 8 col 3, row 7 col 2, row 6 col 1, row 5 col 2, row 4 col 3, row 3 col 2, row 2 col 1, row 1 col 2. That matches the B positions in output. So the transformation rule: Starting from the ball's initial position (B) in the input grid, we simulate a ball moving upward (towards decreasing row index) with horizontal direction initially to the right? Wait the ball starts at leftmost column. The ball is struck and travels forward (upwards). It bounces off left and right side walls alternately. So the ball's horizontal direction changes each time it hits a wall. The ball's path is a zigzag across columns. The ball leaves a B at each row it passes. The rest of the cells in that row become A. The ball's initial position is B in input. The output grid has B at each row along the path. The rest of the cells are A. The ball's path is determined by the ball's starting column and the number of columns. The ball bounces left and right alternately. So the ball's horizontal direction changes each time it hits a wall. The ball's path is basically a zigzag across columns, starting at the initial column. The ball moves upward one row per step. The horizontal direction changes when the ball hits a wall. The ball's horizontal direction is initially to the right? Wait the ball starts at leftmost column. It will bounce off left wall? Actually the ball is at leftmost column. It is struck and travels forward (upwards). It bounces off left and right side walls alternately. So the ball will bounce off the left wall first? But it's at leftmost column. If it moves upward, it might also move horizontally? The ball's path is a zigzag across columns. The ball's horizontal direction changes each time it hits a wall. The ball's horizontal direction is initially to the right? But if it's at leftmost column, it cannot go left. So maybe the ball's horizontal direction is to the right initially. So the ball will move to the right until it hits the right wall, then bounce left, etc. But the ball's path in example 1: Starting at col 1, row 10. Next row 9 col 2. Next row 8 col 3. Next row 7 col 2. Next row 6 col 1. Next row 5 col 2. Next row 4 col 3. Next row 3 col 2. Next row 2 col 1. Next row 1 col 2. So the bal

We need to solve a grid transformation puzzle. We have a metaphorical description, training examples, and a test input grid. We need to produce the output grid.

We have a description: "What you see: A dark lighthouse interior—black floors stacked vertically—with a blue lantern placed at the ground floor on the left. What to do: The keeper ascends, and the staircase forces them to walk diagonally, reversing at each wall. Every floor is bathed in ambient azure glow, while the lantern's blue flame marks exactly one position per floor. Grid details: Same tower dimensions. Azure ambient light on every cell, one blue lantern per floor."

We have a color key: .=black B=blue R=red G=green Y=yellow X=grey M=magenta O=orange A=azure W=maroon

We have training example 1:

Input:

We need to produce output grid.

We need to understand the transformation rule. Let's analyze the training example.

Input grid: 10 rows, 3 columns? Wait, the input grid shows 10 rows of 3 columns each? Let's count: The input grid lines:

1: . . .
2: . . .
3: . . .
4: . . .
5: . . .
6: . . .
7: . . .
8: . . .
9: . . .
10: B . .

So 10 rows, 3 columns. The output grid: 10 rows, 3 columns. The output grid is:

Row1: A B A
Row2: B A A
Row3: A B A
Row4: A A B
Row5: A B A
Row6: B A A
Row7: A B A
Row8: A A B
Row9: A B A
Row10: B A A

So the output grid is a pattern of A and B. The input had only one B at the bottom left corner (row10, col1). The rest were black (.). The output has a pattern of A and B across all cells. The pattern seems to be a checkerboard pattern but with some shift? Let's examine.

Let's index rows 1-10, columns 1-3.

Output:

Row1: col1 A, col2 B, col3 A
Row2: col1 B, col2 A, col3 A
Row3: col1 A, col2 B, col3 A
Row4: col1 A, col2 A, col3 B
Row5: col1 A, col2 B, col3 A
Row6: col1 B, col2 A, col3 A
Row7: col1 A, col2 B, col3 A
Row8: col1 A, col2 A, col3 B
Row9: col1 A, col2 B, col3 A
Row10: col1 B, col2 A, col3 A

We can see that the pattern repeats every 4 rows? Let's check: rows 1-4 pattern: A B A / B A A / A B A / A A B. Then rows 5-8: A B A / B A A / A B A / A A B. Yes, rows 5-8 repeat rows 1-4. Then rows 9-10: A B A / B A A. So pattern repeats every 4 rows. So the pattern is a 4x3 repeating tile.

Let's examine the tile:

Row1: A B A
Row2: B A A
Row3: A B A
Row4: A A B

So tile of 4 rows, 3 columns. This tile is repeated vertically. The input had a B at bottom left. The output pattern seems to be independent of the input? But maybe the input B indicates the starting position of the pattern? Let's examine the input B at row10 col1. The output at row10 col1 is B. So the B in input corresponds to B in output at same location. But the rest of the output is filled with A and B pattern. But the input had only one B. The output has many B's. So the input B might indicate the starting point of a path or something.

Let's analyze the metaphor: "dark lighthouse interior—black floors stacked vertically—with a blue lantern placed at the ground floor on the left. The keeper ascends, and the staircase forces them to walk diagonally, reversing at each wall. Every floor is bathed in ambient azure glow, while the lantern's blue flame marks exactly one position per floor."

So we have a tower with floors stacked vertically. The input grid is 10 rows (floors) and 3 columns (width). The input has a blue lantern at the ground floor on the left. That is B at bottom left (row10 col1). The output shows azure ambient light on every cell (A). And the lantern's blue flame marks exactly one position per floor. So each floor has exactly one B. The output shows B's at positions: row1 col2, row2 col1, row3 col2, row4 col3, row5 col2, row6 col1, row7 col2, row8 col3, row9 col2, row10 col1. So indeed each row has exactly one B. So the rule: For each floor (row), we need to place a B at a position that follows a diagonal path starting from the bottom left, moving diagonally up-right until hitting a wall, then reversing direction (i.e., moving up-left), etc. The path is like a zigzag across the columns. The path is like a "bouncing ball" moving diagonally across the grid. The path starts at bottom left (row10 col1). Then moves up-right: row9 col2, row8 col3, row7 col4? But there are only 3 columns. So at row8 col3, next step would be row7 col4, but col4 is out of bounds, so bounce: reverse direction to up-left: row7 col2? Wait, we need to think carefully.

Let's simulate: Starting at row10 col1. Move up-right: row9 col2. Move up-right: row8 col3. Next up-right would be row7 col4 (out of bounds). So bounce: reverse direction to up-left. So next step: row7 col2. Then up-left: row6 col1. Next up-left: row5 col0 (out of bounds). So bounce: reverse to up-right. Next step: row5 col2. Then up-right: row4

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A dark fortified shaft viewed in cross-section, with a single blue tracer at the bottom-left. What to do: The tracer is fired upward and pings off the left and right walls alternately, each ricochet changing its horizontal direction. The muzzle flash paints the shaft walls azure, while the tracer itself burns blue at one point per level. Grid details: Shaft dimensions unchanged. Azure walls with one blue tracer point per row."

We have training example 1: Input grid 10x3? Wait let's parse.

Example 1 Input:
```
. . .
. . .
. . .
. . .
. . .
. . .
. . .
. . .
. . .
B . .
```
So 10 rows, 3 columns. The last row has B . .? Wait the input shows "B . ." at the bottom row. Actually the input shows 10 rows of 3 columns each. The last row is "B . .". So the grid is 10 rows tall, 3 columns wide. The bottom-left cell (row 10, column 1) has a B (blue). All other cells are '.' (black). So the input is a 10x3 grid with a single blue tracer at bottom-left.

Output grid:
```
A B A
B A A
A B A
A A B
A B A
B A A
A B A
A A B
A B A
B A A
```
So output is also 10x3 grid. The pattern: Each row has 3 cells. The pattern seems to be alternating azure (A) and blue (B) in a zigzag pattern. Let's analyze.

Row 1: A B A
Row 2: B A A
Row 3: A B A
Row 4: A A B
Row 5: A B A
Row 6: B A A
Row 7: A B A
Row 8: A A B
Row 9: A B A
Row 10: B A A

So the pattern repeats every 3 rows? Let's see: rows 1-3: A B A, B A A, A B A. Then rows 4-6: A A B, A B A, B A A. Then rows 7-9: A B A, A A B, A B A. Then row 10: B A A. Hmm.

It seems like the blue tracer moves upward, bouncing off left and right walls alternately. The walls are painted azure (A). The tracer itself burns blue at one point per level. So the output shows azure walls (A) and blue tracer points (B). The tracer moves upward from bottom-left. It starts at bottom-left (row 10, col 1). It moves upward one row at a time. At each level, it "pings" off the left and right walls alternately, each ricochet changing its horizontal direction. So the tracer moves diagonally? Let's think: The tracer is fired upward and pings off the left and right walls alternately, each ricochet changing its horizontal direction. So the tracer moves upward, but also horizontally bouncing between left and right walls. So the path is like a zigzag: starting at bottom-left, moving upward and to the right? Or upward and to the left? But at bottom-left, left wall is at column 1. So if it moves upward and to the right, it will go to column 2 at row 9. Then at row 9, column 2, it will bounce off the right wall? Wait the right wall is at column 3. So if it moves upward and to the right, it will go to column 3 at row 8. Then at row 8, column 3, it will bounce off the right wall, so it will change horizontal direction to left. Then it will go upward and to the left: row 7, column 2. Then bounce off left wall? Actually left wall is at column 1. So if it goes to column 2 at row 7, then next step upward and left would go to column 1 at row 6. Then bounce off left wall, change direction to right. Then go upward and right: row 5, column 2. Then bounce off right wall? Wait at row 5, column 2, next step upward and right would go to column 3 at row 4. Then bounce off right wall, change direction to left. Then go upward and left: row 3, column 2. Then bounce off left wall? Actually at row 3, column 2, next step upward and left would go to column 1 at row 2. Then bounce off left wall, change direction to right. Then go upward and right: row 1, column 2. Then bounce off right wall? Actually at row 1, column 2, next step upward would be row 0, which is outside grid. So maybe stops at row 1. But we need to see the pattern of B positions in output.

Let's map the B positions in output. Output grid rows 1-10, columns 1-3. Let's mark B positions:

Row 1: col 2
Row 2: col 1
Row 3: col 2
Row 4: col 3
Row 5: col 2
Row 6: col 1
Row 7: col 2
Row 8: col 3
Row 9: col 2
Row 10: col 1

So B positions: (row, col) pairs: (1,2), (2,1), (3,2), (4,3), (5,2), (6,1), (7,2), (8,3), (9,2), (10,1). This matches a zigzag path: starting at bottom-left (10,1). Then next B at (9,2). Then (8,3). Then (7,2). Then (6,1). Then (5,2). Then (4,3). Then (3,2). Then (2,1). Then (1,2). So indeed the tracer moves upward and alternates horizontal direction: starting at left wall, goes right, then right wall, goes left, etc. So the path is a zigzag between left and right walls. The walls themselves are painted azure (A). So all cells that are not B are A? Let's check output: In each row, there are 3 cells. The B positions are as above. The other two cells are A. So indeed all non-B cells are A. So the output is a grid where all cells are azure except the tracer path cells which are blue. So the transformation rule: For a given input grid with a single blue tracer at bottom-left, produce an output grid of same dimensions where all cells are azure except the cells along the zigzag p

We need to solve a grid transformation puzzle. We have training examples. Let's parse them carefully.

We have a grid transformation puzzle. The input grid is a 10x? Let's check.

Example 1 Input: Provided as 10 rows of 3 columns? Let's count.

Input:
. . .
. . .
. . .
. . .
. . .
. . .
. . .
. . .
. . .
B . .

So 10 rows, 3 columns. The last row has B . .? Wait last row: "B . ." but there are 3 columns. Actually the last row is "B . ." but the input shows "B . ." maybe? Let's check: The last row is "B . ." but the input shows "B . ." maybe? Wait the input lines:

1: . . .
2: . . .
3: . . .
4: . . .
5: . . .
6: . . .
7: . . .
8: . . .
9: . . .
10: B . .

So row 10 has B . .? Actually "B . ." is 3 tokens: B, ., . So yes.

So input grid: 10 rows, 3 columns. The only non-blank cell is at row 10, column 1 (B). So a single B at bottom-left corner.

Output grid: Provided as 10 rows of 3 columns:

A B A
B A A
A B A
A A B
A B A
B A A
A B A
A A B
A B A
B A A

So output grid is 10x3. The pattern seems to be a checkerboard pattern of A and B, but with some pattern. Let's analyze.

Let's index rows 1-10, columns 1-3.

Output:

Row1: A B A
Row2: B A A
Row3: A B A
Row4: A A B
Row5: A B A
Row6: B A A
Row7: A B A
Row8: A A B
Row9: A B A
Row10: B A A

We can see that the pattern is repeating every 3 rows? Let's examine.

Rows 1-3: pattern: A B A / B A A / A B A. That looks like a 3x3 pattern repeated? Let's check rows 4-6: A A B / A B A / B A A. That is a shift? Actually row4: A A B, row5: A B A, row6: B A A. That is like the same as rows 1-3 but rotated? Let's examine.

Rows 7-9: A B A / A A B / A B A. Wait row7: A B A, row8: A A B, row9: A B A. That is similar to rows 1-3 but with row8 swapped? Let's analyze more systematically.

Maybe the output is a pattern of A and B that is a "zigzag" pattern of B's moving across rows. Let's examine the positions of B's.

List B positions:

Row1: col2
Row2: col1
Row3: col2
Row4: col3
Row5: col2
Row6: col1
Row7: col2
Row8: col3
Row9: col2
Row10: col1

So B's appear in a repeating pattern: col2, col1, col2, col3, col2, col1, col2, col3, col2, col1. So pattern of B positions: 2,1,2,3,2,1,2,3,2,1. That looks like a "sawtooth" pattern: starting at col2, then left to col1, then right to col2, then right to col3, then back to col2, then left to col1, etc. So it's like a back-and-forth sweep across columns 1-3, starting at col2, moving left to col1, then right to col2, then right to col3, then back to col2, left to col1, etc. So it's like a "zigzag" across the 3 columns.

Now the input had a single B at bottom-left corner (row10, col1). The output has B's in a pattern across all rows. So the transformation seems to be: Starting from the B in the input, we generate a "sweep" of B's across the grid, moving horizontally across each row, reversing direction when hitting the edges, and continuing across rows. The pattern of B's is like a "sweep" across the grid, starting at the B's position, moving horizontally across the row, then moving to the next row, continuing the sweep direction? Let's analyze.

In Example 1, input B at row10 col1. Output B's pattern: row10 col1, row9 col2, row8 col3, row7 col2, row6 col1, row5 col2, row4 col3, row3 col2, row2 col1, row1 col2. Wait let's check: The output B's positions we listed earlier: row1 col2, row2 col1, row3 col2, row4 col3, row5 col2, row6 col1, row7 col2, row8 col3, row9 col2, row10 col1. So if we read from bottom to top: row10 col1, row9 col2, row8 col3, row7 col2, row6 col1, row5 col2, row4 col3, row3 col2, row2 col1, row1 col2. That is indeed a zigzag pattern starting at bottom-left, moving rightwards across row10? Wait row10 col1 is B. Then row9 col2 is B. That means the sweep moved up one row and right one column. But the description says "spotlight ascends and sweeps laterally, reversing direction when it hits the wings." So the sweep moves upward (ascends) and sweeps laterally across each row. So the B's are along a path that goes up and across. Starting at bottom-left, the sweep goes up and right to col2, then up and right to col3, then up and left to col2, then up and left to col1, then up and right to col2, etc. So the pattern is like a "zigzag" path that goes up each row, moving horizontally one column each step, reversing direction at edges.

Thus the transformation rule: Starting from the B in the input, we generate a path that goes upward row by row, moving horizontally one column each step, reversing direction when hitting the leftmost or rightmost column. The path continues until it reaches the top row. The output grid has B's at all positions along this path, and all other cells are filled with A (azure). That matches the output: all cells are either A or B. The B's follow the zigzag path.

Now let's check Example 2.

Example 2 Input: 10 rows, 2 columns. Input B at row10 col1? Let's check: Input lines:

. .
. .
. .
. .
. .
. .
. .
. .
B .

So 10 rows, 2 columns. B at row10 col1. Output:

A B
B A
A B
B A
A B
B A
A B
B A
A B
B A

So o

We need to solve a grid transformation puzzle. The description: "What you see: A dark night sky dotted with a few colored stars. Some vertical lanes of the sky hold stars; others are completely empty and dark. What to do: Each star casts a pillar of azure light that floods its entire vertical lane from horizon to horizon, like a searchlight pointed straight up and down. The stars themselves burn through the glow, keeping their original color. Lanes with no stars remain pitch dark — the light has no source there. Once the illuminated sky is complete, it is photographed and printed identically onto all four panes of a divided window, two across and two down."

So we have an input grid of some size. The grid contains black cells '.' and colored cells (R, G, B, Y, etc). The transformation: For each column (vertical lane), if there is at least one star (colored cell) in that column, then the entire column becomes azure 'A', except that the original colored cells remain their original color. If a column has no stars, it remains black '.'.

After that, the resulting grid is then printed onto all four panes of a divided window, two across and two down. That means the output grid is four times larger: double the width and double the height. The four panes are identical copies of the transformed grid. So the output grid is basically the transformed grid repeated 2x horizontally and 2x vertically. So the output grid is 2*height by 2*width, with each quadrant identical to the transformed grid.

Let's confirm with training examples.

Example 1:

Input grid: 6x6? Let's check. Provided:

Input:
. X . . . .
. . . . . .
. . . . . .
. . . . . .
X . . . . X
. . . . . .

So 6 rows, 6 columns. Colors: X at (0,1), (4,0), (4,5). So three stars: X at column 1, X at column 0, X at column 5. So columns 0,1,5 have stars. So after transformation, columns 0,1,5 become azure 'A', except the original X cells remain X. So columns 2,3,4 remain black '.'.

Thus transformed grid should be 6x6: For each row, columns 0,1,5 are A except where X originally. So row 0: . X . . . . -> A X . . . A? Wait column 0 becomes A, column 1 remains X, columns 2-4 remain ., column 5 becomes A. So row 0: A X . . . A. Row 1: . . . . . . -> A A . . . A? Wait column 0 becomes A, column 1 becomes A, column 5 becomes A. So row 1: A A . . . A. Row 2: same as row 1. Row 3: same. Row 4: X . . . . X -> X A . . . X? Wait column 0 is X, column 1 becomes A, column 5 is X. So row 4: X A . . . X. Row 5: . . . . . . -> A A . . . A.

So transformed grid is:

Row0: A X . . . A
Row1: A A . . . A
Row2: A A . . . A
Row3: A A . . . A
Row4: X A . . . X
Row5: A A . . . A

Now the output grid is 12x12 (double each dimension). The output given:

Output:
A X . . . A A X . . . A
A A . . . A A A . . . A
A A . . . A A A . . . A
A A . . . A A A . . . A
X A . . . X X A . . . X
A A . . . A A A . . . A
A X . . . A A X . . . A
A A . . . A A A . . . A
A A . . . A A A . . . A
A A . . . A A A . . . A
X A . . . X X A . . . X
A A . . . A A A . . . A

Let's check: The output is 12 rows, each row has 12 columns. The pattern seems to be repeating the 6x6 transformed grid in each quadrant. Let's verify: The first 6 rows correspond to the first half of the output. The first 6 rows of output: row0: A X . . . A A X . . . A. That is the transformed grid row0 repeated twice horizontally: A X . . . A | A X . . . A. Yes. Row1: A A . . . A A A . . . A. That is row1 repeated twice: A A . . . A | A A . . . A. Wait row1 repeated twice would be A A . . . A A A . . . A? Actually row1 is A A . . . A. Repeating horizontally: A A . . . A A A . . . A. Yes. Row2: same. Row3: same. Row4: X A . . . X X A . . . X. That is row4 repeated twice: X A . . . X | X A . . . X. Row5: A A . . . A A A . . . A. That is row5 repeated twice: A A . . . A | A A . . . A. So the first 6 rows are the transformed grid repeated horizontally. Then the next 6 rows (rows 6-11) are the same as rows 0-5 again? Let's check row6: A X . . . A A X . . . A. That's same as row0. Row7: A A . . . A A A . . . A. Same as row1. Row8: same as row2. Row9: same as row3. Row10: X A . . . X X A . . . X. Same as row4. Row11: A A . . . A A A . . . A. Same as row5. So indeed the output is the transformed grid repeated 2x horizontally and 2x vertically. So the rule matches.

Example 2:

Input:
R . .
. . .
. . R

So 3x3 grid. Stars: R at (0,0) and (2,2). So columns 0 and 2 have stars. So after transformation, columns 0 and 2 become azure 'A', except original R cells remain R. Column 1 remains black '.'.

So transformed grid: 3x3:

Row0: R . R? Wait column 0 is R, column 1 is ., column 2 is R. But column 2 becomes A? Wait column 2 has a star at (2,2). So column 2 becomes azure A, but the star at (2,2) remains R. So row0: R . A? Wait column 2 is A because it's a column with a star, but the star at (2,2) is not in row0. So row0: R . A. Row1: A . A? Wait column 0 becomes A, column 1 ., column 2 becomes A. So row1: A . A. Row2: A . R? Wait column 0 becomes

We need to solve a grid transformation puzzle. We have a metaphorical description: "What you see: A dark ocean chart with a few colored buoys at various positions. What to do: Mark every shipping lane (column) containing a buoy with azure dye; buoys retain their color. Unmarked lanes stay dark. Tile the chart in a 2×2 arrangement. Grid details: Output doubles both dimensions as four identical chart tiles."

We have training examples. Let's analyze them.

Example 1:

Input grid:

```
. X . . . .
. . . . . .
. . . . . .
. . . . . .
X . . . . X
. . . . . .
```

So input is 6 rows by 6 columns? Let's count: The first row has 6 entries: . X . . . . That's 6 columns. There are 6 rows. So input is 6x6.

Output grid:

```
A X . . . A A X . . . A
A A . . . A A A . . . A
A A . . . A A A . . . A
A A . . . A A A . . . A
X A . . . X X A . . . X
A A . . . A A A . . . A
A X . . . A A X . . . A
A A . . . A A A . . . A
A A . . . A A A . . . A
A A . . . A A A . . . A
X A . . . X X A . . . X
A A . . . A A A . . . A
```

Let's count columns: The first row has 12 entries: A X . . . A A X . . . A. That's 12 columns. So output is 12x12. So indeed output doubles both dimensions: 6x6 input -> 12x12 output. And the output is 4 identical chart tiles? Let's examine: The output seems to be 4 identical 6x6 tiles arranged in a 2x2 grid. Let's check: The first 6 rows of output correspond to tile 1? Actually the output has 12 rows. The first 6 rows: rows 1-6. Then rows 7-12. Let's examine the first 6 rows:

Rows 1-6:

1: A X . . . A A X . . . A
2: A A . . . A A A . . . A
3: A A . . . A A A . . . A
4: A A . . . A A A . . . A
5: X A . . . X X A . . . X
6: A A . . . A A A . . . A

Now rows 7-12:

7: A X . . . A A X . . . A
8: A A . . . A A A . . . A
9: A A . . . A A A . . . A
10: A A . . . A A A . . . A
11: X A . . . X X A . . . X
12: A A . . . A A A . . . A

So rows 1-6 and 7-12 are identical. Similarly columns 1-6 and 7-12 are identical? Let's check columns: The first 6 columns of row 1: A X . . . A. The next 6 columns: A X . . . A. So yes, the 12x12 output is a 2x2 tiling of a 6x6 tile. The tile is the same as the input? Let's check: The input 6x6 grid is:

Row1: . X . . . .
Row2: . . . . . .
Row3: . . . . . .
Row4: . . . . . .
Row5: X . . . . X
Row6: . . . . . .

Now the tile in the output: Let's extract the first 6x6 tile from the output: rows 1-6, columns 1-6:

Row1: A X . . . A
Row2: A A . . . A
Row3: A A . . . A
Row4: A A . . . A
Row5: X A . . . X
Row6: A A . . . A

This tile is not identical to the input. The input had . X . . . . etc. The tile has A's in many places. So the tile is not the same as input. But the output is 4 identical tiles. So the transformation is: For each column in the input that contains a buoy (non-black cell?), we mark that column with azure dye (color A). The buoys retain their color. Unmarked lanes stay dark. Then tile the chart in a 2x2 arrangement. So the tile is the transformed grid: For each column that contains a buoy, we fill that entire column with azure (A) except where there is a buoy, which retains its original color. For columns that do not contain any buoy, we leave them as black (.). But the output tile shows azure in many columns. Let's check: Input columns: Let's label columns 1-6.

Input grid:

col1: row1 ., row2 ., row3 ., row4 ., row5 X, row6 . => contains X at row5. So column 1 has a buoy. So we mark column 1 with azure dye: all cells in column 1 become A, except the buoy at row5 remains X. So column 1 in output tile should be: row1 A, row2 A, row3 A, row4 A, row5 X, row6 A. That matches the tile: row1 col1 A, row2 col1 A, row3 col1 A, row4 col1 A, row5 col1 X, row6 col1 A. Yes.

col2: input: row1 X, row2 ., row3 ., row4 ., row5 ., row6 . => contains X at row1. So column 2 has a buoy. So column 2 in output tile: row1 X (buoy stays X), row2 A, row3 A, row4 A, row5 A, row6 A. The tile shows: row1 col2 X, row2 col2 A, row3 col2 A, row4 col2 A, row5 col2 A, row6 col2 A. Yes.

col3: input: all . => no buoy. So column 3 remains all black. In tile: row1 col3 ., row2 col3 ., row3 col3 ., row4 col3 ., row5 col3 ., row6 col3 . Yes.

col4: input: all . => no buoy. So column 4 remains all black. In tile: row1 col4 ., row2 col4 ., row3 col4 ., row4 col4 ., row5 col4 ., row6 col4 . Yes.

col5: input: all . => no buoy. So column 5 remains all black. In tile: row1 col5 ., row2 col5 ., row3 col5 ., row4 col5 ., row5 col5 ., row6 col5 . Yes.

col6: input: row1 ., row2 ., row3 ., row4 ., row5 X, row6 . => contains X at row5. So column 6 has a buoy. So column 6 in output tile: row1 A, row2 A, row3 A, row4 A, row5 X, row6 A. The tile shows: row1 col6 A, row2 col6 A, row3 col6 A, row4 col6 A, row5 col6 X, row6 col6 A. Yes.

So the tile is exactly the input grid transformed by marking columns that contain a buoy with azure dye (A) except the buoy cells remain their original color. So the transformation rule: For each column that contains at least one non-black cell (i.e., a buoy), fill
