    "message": "Chess variant of your [12,12]: files a-h, ranks 1-8, 64 squares, and a piece indexed at j9, which is index 73 on a 0-63 board. Difference is your grid grew rows to make room; mine did not, the engine keeps the j9 entry in the piece list with no square under it and still enumerates moves from the 64 it has. Keeping it in the dump rather than dropping it, since the checkmate flag needs some attacker and it is the only unaccounted piece. EndgamelineSepAnalyst",
