Root Cause:
- GAMES_CONFIG used 'memory-lightning' as key but validator was registered as 'memory-quiz'
- When rooms were created with gameName 'memory-lightning', getValidator() couldn't find the validator
- This caused all move validations to fail, breaking configuration changes and guess validation
Key Changes:
1. Fixed game identifier mismatch:
- Changed GAMES_CONFIG key from 'memory-lightning' to 'memory-quiz'
- Updated games/page.tsx to use 'memory-quiz' for routing
2. Completed Memory Quiz room-based multiplayer implementation:
- Added MemoryQuizGameValidator with all 9 move types (START_QUIZ, NEXT_CARD, SHOW_INPUT_PHASE, ACCEPT_NUMBER, REJECT_NUMBER, SET_INPUT, SHOW_RESULTS, RESET_QUIZ, SET_CONFIG)
- Created RoomMemoryQuizProvider for network-synchronized gameplay
- Implemented optimistic client-side updates with server validation
- Added proper serialization handling (send numbers instead of React components)
- Split memory-quiz/page.tsx into modular components (SetupPhase, DisplayPhase, InputPhase, ResultsPhase)
3. Updated socket-server:
- Fixed to use getValidator() instead of hardcoded matchingGameValidator
- Added game-specific initial state handling for both 'matching' and 'memory-quiz'
4. Fixed test failures from arcade_sessions schema changes:
- Updated arcade-session-validation.e2e.test.ts to create rooms before sessions (roomId is now primary key)
- Added missing playerMetadata and playerHovers fields to arcade-session-integration.test.ts
- Skipped obsolete test in orphaned-session-cleanup.test.ts (roomId can't be null as it's the primary key)
5. Code quality fixes:
- Removed unused type imports from room-moderation.ts
- Changed to optional chain in MemoryQuizGameValidator.ts
- Removed unnecessary fragment in MemoryQuizGame.tsx
Testing:
- All modified tests updated to match new schema requirements
- TypeScript errors resolved (excluding pre-existing @soroban/abacus-react issues)
- Lint passes with 0 errors and 0 warnings
