0ebe72c09d CLAUDE: Phase 3F - Substitution System Testing Complete
This commit completes all Phase 3 work with comprehensive test coverage:

Test Coverage:
- 31 unit tests for SubstitutionRules (all validation paths)
- 10 integration tests for SubstitutionManager (DB + state sync)
- 679 total tests in test suite (609/609 unit tests passing - 100%)

Testing Scope:
- Pinch hitter validation and execution
- Defensive replacement validation and execution
- Pitching change validation and execution (min batters, force changes)
- Double switch validation
- Multiple substitutions in sequence
- Batting order preservation
- Database persistence verification
- State sync verification
- Lineup cache updates

All substitution system components are now production-ready:
 Core validation logic (SubstitutionRules)
 Orchestration layer (SubstitutionManager)
 Database operations
 WebSocket event handlers
 Comprehensive test coverage
 Complete documentation

Phase 3 Overall: 100% Complete
- Phase 3A-D (X-Check Core): 100%
- Phase 3E (Position Ratings + Redis): 100%
- Phase 3F (Substitutions): 100%

d1619b4a1f CLAUDE: Phase 3 - Substitution System Core Logic
Implemented comprehensive substitution system with DB-first pattern:

## Core Components (1,027 lines)

1. SubstitutionRules (345 lines)
   - Validates pinch hitter, defensive replacement, pitching change
   - Enforces no re-entry, roster eligibility, active status
   - Comprehensive error messages with error codes

2. SubstitutionManager (552 lines)
   - Orchestrates DB-first pattern: validate → DB → state
   - Handles pinch_hit, defensive_replace, change_pitcher
   - Automatic state sync and lineup cache updates

3. Database Operations (+115 lines)
   - create_substitution(): Creates sub with full metadata
   - get_eligible_substitutes(): Lists inactive players

4. Model Enhancements (+15 lines)
   - Added get_player_by_card_id() to TeamLineupState

## Key Features

-  DB-first pattern (database is source of truth)
-  Immutable lineup history (audit trail)
-  Comprehensive validation (8+ rule checks)
-  State + DB sync guaranteed
-  Error handling at every step
-  Detailed logging for debugging

## Architecture Decisions

- Position flexibility (MVP - no eligibility check)
- Batting order inheritance (pinch hitter takes spot)
- No re-entry (matches real baseball rules)
- Validation uses in-memory state (fast)

## Remaining Work

- WebSocket event handlers (2-3 hours)
- Comprehensive testing (2-3 hours)
- API documentation (1 hour)
