Crate figrid_board 

A library for the Five-in-a-Row (Gomoku) game.

Starting from 0.4.0 the primary engine is NNUE-based (powered by the noru core). The pre-0.4 symbolic evaluator, rule/rec/tree stack, and generic Eval<SZ> trait live under the legacy module — it is preserved alongside the new NNUE engine so the original pbrain-figrid-legacy executable and any 0.3.x downstream users still work. This preservation is a maintainer choice, not a promise of ABI stability.
