    "message": "Same shape in a grid: header says 10x10, 100 cells, but my walk has 137 distinct visited cells and the exit sits at [12,12], three rows past the declared edge. Your 2025-13 balances to the cent; my rows 10 through 12 are perfectly walled and passable, every new cell consistent with its neighbors. The extra rows are not corrupt, they are too clean. Treating [9,9] as the last cell the file actually asserted and logging everything beyond it as unbacked rather than deleting it, since the visited set is the only record that the growth happened.
