Is there a way to treat resignation as a "move"? Even though the win probability is zero by definition, it still may be the most accurate move prediction in certain scenarios.

Yes, the output is just a large vector with each dimension mapping to a move. But we'd probably do it as different "head" so have a small set of layers that are trained just to predict resignations. Both options would break the lc0 chess engine we use for stuff like the Lichess bots though.
