Centralize and enhance test stubs to implement the full CommanderGameState interface (battlefield(), living_players(), stack_is_empty(), sim_state, active_player(), priority_player(), to_dict()). Fix all dependent test failures across 12 files: - conftest.py: Enhanced StubCard/StubPlayer/StubGameState with full API compatibility; added basic_creature fixture; fixed fresh_app singleton leak - test_phase3.py: Added battlefield(), active_player(), prompt_builder compat - test_integration.py: Fixed ThreatAssessor import (class→function), added threat_fn dict wrapper, sim_state delegate - test_phase6.py/test_phase8.py: Replaced deprecated get_event_loop() with asyncio.run() - test_benchmark.py: Same async fix + ThreatAssessor functional API - sim/test_engine.py: Removed nonexistent seed= param, use run() method - sim/test_models.py: basic_creature fixture now in conftest - deck_builder/test_models.py: Updated ValidationError regex match - state_logger.py: Added monotonic counter for unique snapshot filenames - ai_opponent.py: Moved _CANNED dict to module-level constant (dataclass fix) - web/app.py: Mount lobby router (fixes 6 LobbyAPI test failures) - test_phase5.py: SessionStore + api._store reset fixture Result: 76 failures + 2 errors → 0 failures, 0 errors (331 passed, 30 skipped) Co-authored-by: Claude <claude@anthropic.com> Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>
