TASK STATEMENT

official task contract and visible grid metadata

Grid task 7491f3cf ships 4 demonstration pairs and 1 test input as integer matrices over symbols 0-9.

Demonstration sizes: pair 1 7×25 to 7×25; pair 2 7×25 to 7×25; pair 3 7×25 to 7×25; pair 4 7×25 to 7×25.

Cell-level differences across each demonstration: pair 1 changes 11 of 175 cells; pair 2 changes 11 of 175 cells; pair 3 changes 10 of 175 cells; pair 4 changes 11 of 175 cells.

Demonstration inputs use symbols 0, 1, 2, 3, 4, 5, 6, 7, 8, 9; demonstration outputs use symbols 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

The test input measures 7×25, uses symbols 2, 3, 5, 7, 8, runs 43% symbol 2, and splits into 4 four-connected regions of cells that are not symbol 2. It matches none of its own mirrors or half-turn.

No transformation rule is written down anywhere in the task. Infer it from the demonstrations and construct the exact output grid for each test input; every cell must match.

DEMONSTRATION GRIDS

Compare the shipped grids cell by cell.

Every demonstration pair and every test input is printed exactly as the task file carries it: one line per row, one digit per cell. Diff these rows against the grids in front of you to confirm the match.

Symbols in use: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. Grids are rectangular integer matrices; a cell value is a colour index, not a magnitude.
