Atari report order depends on scan order · case 03
Reports are emitted in row-major discovery order instead of sorted order.
Case contract
Input a board. Report every chain with exactly one distinct liberty as [colour, lib_row, lib_col, chain_size], sorted ascending.
Why this case matters
Go servers and scoring tools compute this value automatically; a wrong answer changes a game result.
One recorded failure
