Cal Corum 72a3b94ce7 CLAUDE: Add transaction handling for multi-step DB operations ... 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. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>		2025-11-19 16:39:01 -06:00
