e147ab17f1 CLAUDE: Phase 3F - Substitution System WebSocket Events
Implemented complete WebSocket integration for real-time player substitutions.
System is now 80% complete - only tests remain.

## WebSocket Events Implemented (600 lines)

### Event Handlers (backend/app/websocket/handlers.py):
1. request_pinch_hitter - Pinch hitter substitution
   - Validates: game_id, player_out_lineup_id, player_in_card_id, team_id
   - Executes: SubstitutionManager.pinch_hit()
   - Broadcasts: player_substituted (all clients), substitution_confirmed (requester)
   - Error codes: MISSING_FIELD, INVALID_FORMAT, NOT_CURRENT_BATTER, etc.

2. request_defensive_replacement - Defensive replacement
   - Additional field: new_position (P, C, 1B, 2B, 3B, SS, LF, CF, RF)
   - Executes: SubstitutionManager.defensive_replace()
   - Same broadcast pattern as pinch hitter

3. request_pitching_change - Pitching change
   - Validates minimum batters faced (handled in SubstitutionManager)
   - Executes: SubstitutionManager.change_pitcher()
   - Broadcasts new pitcher to all clients

4. get_lineup - Get active lineup for team
   - Returns: lineup_data with all active players
   - Uses: StateManager cache (O(1)) or database fallback
   - Purpose: UI refresh after substitutions

### Event Pattern (follows existing handlers):
- Validate inputs (UUID format, required fields, game exists)
- Create SubstitutionManager instance with DatabaseOperations
- Execute substitution (validate → DB → state)
- Broadcast player_substituted to game room
- Send substitution_confirmed to requester
- Error handling with specific error codes

### Events Emitted:
- player_substituted (broadcast) - Includes: type, lineup IDs, position, batting_order
- substitution_confirmed (requester) - Success confirmation with new_lineup_id
- substitution_error (requester) - Validation error with error code
- lineup_data (requester) - Active lineup response
- error (requester) - Generic error

## Documentation Updates (350 lines)

### backend/app/websocket/CLAUDE.md:
- Complete handler documentation with examples
- Event data structures and response formats
- Error code reference (MISSING_FIELD, INVALID_FORMAT, NOT_CURRENT_BATTER, etc.)
- Client integration examples (JavaScript)
- Complete workflow diagrams
- Updated event summary table (+8 events)
- Updated Common Imports section

### .claude/implementation/ updates:
- NEXT_SESSION.md: Marked Task 1 complete, updated to 80% done
- SUBSTITUTION_SYSTEM_SUMMARY.md: Added WebSocket section, updated status
- GAMESTATE_REFACTOR_PLAN.md: Marked complete
- PHASE_3_OVERVIEW.md: Updated all phases to reflect completion
- phase-3e-COMPLETED.md: Created comprehensive completion doc

## Architecture

### DB-First Pattern (maintained):
```
Client Request → WebSocket Handler
    ↓
SubstitutionManager
    ├─ SubstitutionRules.validate_*()
    ├─ DatabaseOperations.create_substitution() (DB first!)
    ├─ StateManager.update_lineup_cache()
    └─ Update GameState if applicable
    ↓
Success Responses
    ├─ player_substituted (broadcast to room)
    └─ substitution_confirmed (to requester)
```

### Error Handling:
- Three-tier: ValidationError, GameValidationError, Exception
- Specific error codes for each failure type
- User-friendly error messages
- Comprehensive logging at each step

## Status Update

**Phase 3F Substitution System**: 80% Complete
-  Core logic (SubstitutionRules, SubstitutionManager) - 1,027 lines
-  Database operations (create_substitution, get_eligible_substitutes)
-  WebSocket events (4 handlers) - 600 lines
-  Documentation (350 lines)
-  Unit tests (20% remaining) - ~300 lines needed
-  Integration tests - ~400 lines needed

**Phase 3 Overall**: ~97% Complete
- Phase 3A-D (X-Check Core): 100%
- Phase 3E (GameState, Ratings, Redis, Testing): 100%
- Phase 3F (Substitutions): 80%

## Files Modified

backend/app/websocket/handlers.py (+600 lines)
backend/app/websocket/CLAUDE.md (+350 lines)
.claude/implementation/NEXT_SESSION.md (updated progress)
.claude/implementation/SUBSTITUTION_SYSTEM_SUMMARY.md (added WebSocket section)
.claude/implementation/GAMESTATE_REFACTOR_PLAN.md (marked complete)
.claude/implementation/PHASE_3_OVERVIEW.md (updated all phases)

   - 15+ pinch hitter tests
   - 12+ defensive replacement tests
   - 10+ pitching change tests
2. Integration tests for SubstitutionManager (~400 lines)
   - Full DB + state sync flow
   - State recovery verification
   - Error handling and rollback

d560844704 CLAUDE: Phase 3E-Prep - Refactor GameState to use full LineupPlayerState objects
**Architectural Improvement**: Unified player references in GameState

**Changed**: Make all player references consistent
- BEFORE: current_batter/pitcher/catcher were IDs (int)
- AFTER: current_batter/pitcher/catcher are full LineupPlayerState objects
- Matches pattern of on_first/on_second/on_third (already objects)

**Benefits**:
1. Consistent API - all player references use same type
2. Self-contained GameState - everything needed for resolution
3. No lookups needed - direct access to player data
4. Sets foundation for Phase 3E-Main (adding position ratings)

**Files Modified**:
- app/models/game_models.py: Changed current_batter/pitcher/catcher to objects
- app/core/game_engine.py: Updated _prepare_next_play() to populate full objects
- app/core/state_manager.py: Create placeholder batter on game creation
- tests/unit/models/test_game_models.py: Updated all 27 GameState tests

**Database Operations**:
- No schema changes needed
- Play table still stores IDs (for referential integrity)
- IDs extracted from objects when saving: state.current_batter.lineup_id

**Testing**:
- All 27 GameState tests passing
- No regressions in existing functionality
- Type checking passes

**Next**: Phase 3E-Main - Add PositionRating dataclass and load ratings at game start
