- Requires config system changes across validators.py and game_models.py
- Appropriate for technical debt phase
Issue #9 (Cleanup on abandon): Already fixed (part of Issue #3)
- _cleanup_game_resources() called in end_game() at line 1109
Issue #10 (Direct state mutation): Architectural acknowledgment

Issue #5 from code review - resolve_play and resolve_manual_play shared
~70% of their code causing maintenance burden and divergent behavior risk.
Changes:
- Extracted common finalization logic to new _finalize_play() method
- resolve_play reduced from ~150 lines to ~60 lines
- resolve_manual_play reduced from ~135 lines to ~60 lines
- Single source of truth for: roll tracking, state capture, transaction
handling, inning advance, cleanup, and state updates
Benefits:
- Changes to play finalization only need to be made in one place
- Reduced risk of divergent behavior between resolution modes
- Better testability and maintainability
All 739 unit tests passing (1 flaky probabilistic test occasionally fails).

Issue #4 from code review - multi-step database operations were not
wrapped in transactions, risking partial state on failure.
Changes:
- Modified save_play() and update_game_state() in DatabaseOperations
to accept optional session parameter for transaction grouping
- Wrapped resolve_play() DB operations in single atomic transaction
- Wrapped resolve_manual_play() DB operations in single atomic transaction
- Transaction commits atomically or rolls back entirely on failure
Pattern: When session provided, use flush() for IDs without committing;
caller controls transaction. When no session, create internal transaction.
All 739 unit tests passing.
