+// This harness's job is to validate _GetAttacksBB against a fixed
+// baseline (the real asm/CROUTINES implementation), not to compare
+// the engine's own current GetAttacks macro target against itself --
+// but chess.h's GETATTACKS_BITBOARD toggle (board_representation/
+// MIGRATION.md section 6) can make that macro resolve to
+// _GetAttacksBB. Undefine it here so every "GetAttacks(...)" call
+// below always reaches the real asm/CROUTINES function (still
+// declared under that name in chess.h, just no longer macro-routed),
+// regardless of which implementation is live in production.
