Cython implementation in heuristic_cy.pyx achieves ~2.55× speedup on opponent_act_seconds (200-game eval: 59.20s → 23.24s). Original Python implementation preserved verbatim in heuristic_py.py as the equivalence reference. Action-sequence equivalence is verified by test_safe_heuristic_equivalence.py against seeded game corpora. Key implementation notes: - File-local wraparound=True override required for negative discard indexing; Cython global wraparound=False would segfault. - annotation_typing=False preserves verbatim Python semantics. - _CachedState materializes hands/expeditions/discards/deck once per act() call — this is the dominant performance win. Further C-array optimization of _card_value_for_me / _card_value_for_opponent / _color_commitment / _bonus_potential is deferred. The current 2.55× delivers most of the dense-eval future benefit; further work is gated on actually adopting denser eval schedules (eval_every=5, games=1000).
