Complete architecture simplification: 54+ files → 37 files
- Removed 11 duplicate router files (auth.py, users.py, decks.py, card_router.py, interactions.py, user_data.py, rooms.py, games/router.py, refresh.py, card_import.py, ws.py) - Removed duplicate core files (logging_config.py, settings.py) - Removed unused services (card_mirror_service.py, mtgjson_loader.py, mtgjson_uploader.py) - Removed unused schemas (proto_messages.py, protocol_constants.py) - Created run.py startup script for simple execution - Created app/core/config.py for unified configuration management - Created app/core/logging.py for logging configuration - Consolidated routers into 6 focused files (auth_router.py, users_router.py, decks_router.py, cards_router.py, user_data_router.py, games_router.py) - Updated all imports to use consolidated model paths - Added backward compatibility aliases in database.py - Created SIMPLIFICATION_SUMMARY.md documentation Architecture improvements: - Single unified database engine with auto-detection (SQLite/PostgreSQL) - Consolidated models into 2 files (models.py, mtg_models.py) - Clean router structure with one file per domain - Simplified configuration with sensible defaults - SQLite by default for development, PostgreSQL for production Testing: - All imports verified working - App loads successfully - Ready for development and testing
