CLAUDE: Phase 3F - Substitution System WebSocket Events

Browse Source 
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

- ✅ WebSocket events (4 handlers) - 600 lines
- ✅ Documentation (350 lines)
- ⏳ Unit tests (20% remaining) - ~300 lines needed

### 4. Phase 3E-Prep: GameState Refactoring (2025-11-04) - **COMPLETED** ✅
#### Critical Architectural Improvement (cf7cc23, 76e0142, bb78de2, e6bd66e)
- **Problem**: GameState had inconsistent player references (runners were objects, batter/pitcher/catcher were IDs)
- **Solution**: Refactored all player references to use full `LineupPlayerState` objects
#### Files Modified (7 files):
- `backend/app/models/game_models.py` - Changed `current_batter_lineup_id` → `current_batter: LineupPlayerState`
- `backend/app/core/game_engine.py` - Updated `_prepare_next_play()` to set full objects

- `backend/terminal_client/repl.py` - Updated REPL commands
#### Benefits Realized:
- ✅ Consistent API for all player references
- ✅ Self-contained GameState (no external lookups needed)
- ✅ Simplified PlayResolver (direct access to player data)
- ✅ Enables position ratings integration (Phase 3E-Main prerequisite)
#### Bug Fixes Included:
- DO3 (double-3) batter advancement fix (76e0142) - Batter now correctly reaches 2B, not 3B
- Runner advancement for new GameState structure (cf7cc23) - Fixed AttributeError
- Game recovery for new structure (e6bd66e) - State persistence working
#### Tests: 34 runner advancement tests passing, all integration tests passing
### 5. Phase 3E Testing: X-Check Terminal Integration (2025-11-04) - **COMPLETED** ✅
#### Terminal Client Enhancements (bb78de2, 8fb740f)
- **New Feature**: `resolve_with x-check <position>` command
- Complete X-Check resolution with defense tables and error charts
- Shows all resolution steps with audit trail
- Works with actual player ratings from PD API
#### X-Check Commands in Help System (8fb740f):
- `roll_jump` / `test_jump` - Jump roll testing
- `roll_fielding` / `test_fielding` - Fielding roll testing
- `test_location` - Hit location testing
- `rollback` - Undo last play
- `force_wild_pitch` / `force_passed_ball` - Force specific outcomes
#### Usage Example:
```bash
⚾ > defensive
⚾ > offensive
⚾ > resolve_with x-check SS # Test X-Check to shortstop
```
#### Documentation Updates (c7b376d):
- `backend/app/models/CLAUDE.md` - Documented GameState refactoring

- **New Policy**: All unit tests must pass before commits
- Documented in `backend/CLAUDE.md` and `tests/CLAUDE.md`
#### Git Hook System Created:
- `.git-hooks/pre-commit` - Automatically runs all unit tests before each commit
- `.git-hooks/install-hooks.sh` - Easy installation script
- `.git-hooks/README.md` - Complete hook documentation
#### Test Fixes (beb939b):

---
## Phase 3E Sub-Phases
### Phase 3E-Prep: GameState Refactoring ✅
**Date**: 2025-11-04
**Duration**: ~2 hours
**Commits**: cf7cc23, 76e0142, bb78de2, e6bd66e, c7b376d
#### Problem Solved
GameState had inconsistent player references:
- **Before**: Runners were `LineupPlayerState` objects, but batter/pitcher/catcher were just IDs
- **After**: All player references are full `LineupPlayerState` objects
#### Benefits Realized
1. **Architectural Consistency**: Uniform API for all player references
2. **Self-Contained State**: No external lookups needed during play resolution
3. **Simplified PlayResolver**: Direct access to player data
4. **Prerequisite for Position Ratings**: Enables attaching ratings to player objects
#### Files Modified (7 files)
1. `backend/app/models/game_models.py`
- Changed `current_batter_lineup_id: int` → `current_batter: LineupPlayerState`
- Changed `current_pitcher_lineup_id` → `current_pitcher: LineupPlayerState`
- Changed `current_catcher_lineup_id` → `current_catcher: LineupPlayerState`
2. `backend/app/core/game_engine.py`
- Updated `_prepare_next_play()` to set full objects instead of IDs
- Changes: `state.current_batter_lineup_id = batter.id` → `state.current_batter = batter`
3. `backend/app/core/play_resolver.py`
- Updated all references: `state.current_batter_lineup_id` → `state.current_batter.lineup_id`
- Direct access to player data in X-Check resolution
4. `backend/app/core/runner_advancement.py` (cf7cc23)
- Fixed 17 references to use new structure
- Changed: `state.current_batter_lineup_id` → `state.current_batter.lineup_id`
5. `backend/app/core/state_manager.py` (e6bd66e)
- Fixed game recovery for new structure
- State persistence working with full objects
6. `backend/terminal_client/display.py`
- Updated status display to access `.lineup_id` from objects
7. `backend/terminal_client/repl.py`
- Updated REPL commands to use new structure
#### Bug Fixes Included
1. **DO3 Batter Advancement** (76e0142)
- Fixed DO3 (double-3) to correctly place batter on 2B instead of 3B
- DO3 means: Double (batter to 2B), runners advance 3 bases
2. **Game Recovery** (e6bd66e)
- Fixed state recovery after server restart
- Properly reconstructs full player objects from database
3. **Runner Advancement** (cf7cc23)
- Fixed AttributeError: 'GameState' object has no attribute 'current_batter_lineup_id'
- All 34 runner advancement tests passing
#### Test Results
- ✅ 34 runner advancement tests passing
- ✅ All integration tests passing
- ✅ Game recovery working
- ✅ No regressions in existing functionality
#### Documentation
- Updated `backend/app/models/CLAUDE.md` (c7b376d)
- Updated `backend/terminal_client/CLAUDE.md` (c7b376d)
- Complete migration guide with before/after examples

### Phase 3E-Main: Position Ratings Integration ✅
**Date**: 2025-11-03
**Duration**: ~4 hours
**Commits**: 02e816a, 7d15018
#### Deliverables Completed
1. **PD API Client** (`backend/app/services/pd_api_client.py`)
- Async HTTP client for fetching position ratings from PD API
- Endpoint: `/api/cardpositions/player/{player_id}`
- Proper error handling and retries
- Returns `PositionRating` objects
2. **Position Rating Service** (`backend/app/services/position_rating_service.py`)
- Migrated from in-memory cache to Redis
- Cache key: `position_rating:{player_id}:{position}`
- TTL: 24 hours
- Graceful degradation if Redis unavailable
3. **Redis Client** (`backend/app/services/redis_client.py`)
- Async Redis client with connection pooling
- Startup/shutdown lifecycle management
- Used for position rating caching
4. **Configuration** (`backend/app/config.py`)
- Added `redis_url` setting
- Redis connection string configuration
5. **Application Lifecycle** (`backend/app/main.py`)
- Redis startup on app initialization
- Redis shutdown on app termination
- Proper cleanup handling
#### Performance Achieved
**Before** (PD API direct):
- API call: ~0.274s per position rating lookup
- Multiple lookups per game = slow
**After** (Redis cache):
- Cache hit: ~0.000361s per lookup
- **760x speedup achieved** ✅
- Negligible overhead during game play
#### Test Results
- ✅ Live Redis integration test validated (10 verification steps)
- ✅ Position ratings correctly loaded at lineup creation
- ✅ Cache invalidation working correctly
- ✅ API fallback working when cache miss

### Substitution Event Handlers (2025-11-04)
The substitution system enables real-time player substitutions during gameplay. All substitution events follow the same pattern: validate → execute → broadcast.
---
#### `request_pinch_hitter(sid, data)`
**Purpose**: Replace current batter with a bench player (pinch hitter substitution).
**Event Data**:
```python
{
"game_id": "123e4567-e89b-12d3-a456-426614174000",
"player_out_lineup_id": 10, # Lineup ID of player being removed
"player_in_card_id": 201, # Card/player ID of substitute
"team_id": 1 # Team making substitution
}
```
**Flow**:
1. Validate game_id (UUID format, game exists)
2. Validate all required fields present
3. TODO: Verify user is authorized for this team
4. Create `SubstitutionManager` instance
5. Execute `pinch_hit()` with DB-first pattern (validate → DB → state)
6. If successful: Broadcast `player_substituted` to game room
7. If successful: Send `substitution_confirmed` to requester
8. If failed: Send `substitution_error` with error code
**Emits**:
- `player_substituted` → Broadcast to game room on success
- `substitution_confirmed` → To requester on success
- `substitution_error` → To requester if validation fails
- `error` → To requester if processing fails
**Success Broadcast Structure**:
```python
{
"type": "pinch_hitter",
"player_out_lineup_id": 10,
"player_in_card_id": 201,
"new_lineup_id": 25,
"position": "RF",
"batting_order": 3,
"team_id": 1,
"message": "Pinch hitter: #3 now batting"
}
```
**Error Codes**:
- `MISSING_FIELD` - Required field not provided
- `INVALID_FORMAT` - Invalid game_id UUID
- `NOT_CURRENT_BATTER` - Can only pinch hit for current batter
- `PLAYER_ALREADY_OUT` - Player has already been removed from game
- `NOT_IN_ROSTER` - Substitute not on team roster
- `ALREADY_ACTIVE` - Substitute already in game
**Rules Enforced** (by SubstitutionManager):
- Can only pinch hit for current batter
- Substitute must be on roster and inactive
- No re-entry: removed players can't return
- Substitute takes batting order of replaced player
---
#### `request_defensive_replacement(sid, data)`
**Purpose**: Replace a defensive player (improve defense, defensive substitution).
**Event Data**:
```python
{
"game_id": "123e4567-e89b-12d3-a456-426614174000",
"player_out_lineup_id": 12, # Lineup ID of player being removed
"player_in_card_id": 203, # Card/player ID of substitute
"new_position": "SS", # Position for substitute (P, C, 1B, 2B, 3B, SS, LF, CF, RF)
"team_id": 1 # Team making substitution
}
```
**Flow**:
1. Validate game_id and all required fields (including new_position)
2. TODO: Verify user is authorized for this team
3. Execute `defensive_replace()` via SubstitutionManager
4. Broadcast `player_substituted` to game room
5. Send `substitution_confirmed` to requester
**Emits**:
- `player_substituted` → Broadcast to game room on success
- `substitution_confirmed` → To requester on success
- `substitution_error` → To requester if validation fails
- `error` → To requester if processing fails
**Success Broadcast Structure**:
```python
{
"type": "defensive_replacement",
"player_out_lineup_id": 12,
"player_in_card_id": 203,
"new_lineup_id": 26,
"position": "SS",
"batting_order": 6, # Keeps original batting order if in lineup
"team_id": 1,
"message": "Defensive replacement: SS"
}
```
**Rules Enforced**:
- Substitute must be on roster and inactive
- If replaced player was in batting order, substitute takes their spot
- Valid defensive positions: P, C, 1B, 2B, 3B, SS, LF, CF, RF, DH
- No position eligibility check in MVP (any player can play any position)
---
#### `request_pitching_change(sid, data)`
**Purpose**: Replace current pitcher with a reliever (pitching change).
**Event Data**:
```python
{
"game_id": "123e4567-e89b-12d3-a456-426614174000",
"player_out_lineup_id": 1, # Lineup ID of pitcher being removed
"player_in_card_id": 205, # Card/player ID of relief pitcher
"team_id": 1 # Team making substitution
}
```
**Flow**:
1. Validate game_id and all required fields
2. TODO: Verify user is authorized for this team
3. Execute `change_pitcher()` via SubstitutionManager
4. Broadcast `player_substituted` to game room
5. Send `substitution_confirmed` to requester
**Emits**:
- `player_substituted` → Broadcast to game room on success
- `substitution_confirmed` → To requester on success
- `substitution_error` → To requester if validation fails
- `error` → To requester if processing fails
**Success Broadcast Structure**:
```python
{
"type": "pitching_change",
"player_out_lineup_id": 1,
"player_in_card_id": 205,
"new_lineup_id": 27,
"position": "P",
"batting_order": 9, # Typically 9th in lineup
"team_id": 1,
"message": "Pitching change: New pitcher entering"
}
```
**Rules Enforced**:
- Pitcher must have faced at least 1 batter (unless injury - not yet implemented)
- New pitcher must be on roster and inactive
- New pitcher takes pitching position immediately
---
#### `get_lineup(sid, data)`
**Purpose**: Retrieve current active lineup for a team (UI refresh after substitutions).
**Event Data**:
```python
{
"game_id": "123e4567-e89b-12d3-a456-426614174000",
"team_id": 1 # Team to get lineup for
}
```
**Flow**:
1. Validate game_id and team_id
2. TODO: Verify user has access to view this lineup
3. Try StateManager cache (O(1) lookup)
4. If not cached, load from database
5. Send `lineup_data` with active players only
**Emits**:
- `lineup_data` → To requester with active lineup
- `error` → To requester if validation fails
**Response Structure**:
```python
{
"game_id": "123e4567-...",
"team_id": 1,
"players": [
{
"lineup_id": 10,
"card_id": 101,
"position": "RF",
"batting_order": 3,
"is_active": true,
"is_starter": true
},
{
"lineup_id": 25, # Pinch hitter
"card_id": 201,
"position": "RF",
"batting_order": 3,
"is_active": true,
"is_starter": false # Substitute
},
# ... 7 more active players
]
}
```
**Use Cases**:
- Refresh lineup display after substitution
- Show bench players (is_active=false) for substitution UI
- Verify substitution was applied correctly
**Performance**:
- Cache hit: O(1) - instant response
- Cache miss: Single DB query to load lineup
---
### Substitution Event Flow
**Complete Substitution Workflow**:
```
Client (Manager)
↓
socket.emit('request_pinch_hitter', {
game_id, player_out_lineup_id, player_in_card_id, team_id
})
↓
WebSocket Handler (validate inputs)
↓
SubstitutionManager.pinch_hit()
├─ SubstitutionRules.validate_pinch_hitter()
├─ DatabaseOperations.create_substitution()
│ ├─ Mark old player inactive
│ └─ Create new lineup entry
├─ StateManager.update_lineup_cache()
└─ Update GameState.current_batter (if applicable)
↓
Success Response
├─ player_substituted (broadcast to all clients)
└─ substitution_confirmed (to requester)
↓
Client Updates
├─ Lineup display refreshed
├─ Bench updated
└─ Game log updated
```
**Client-Side Integration Example**:
```javascript
// Request pinch hitter
socket.emit('request_pinch_hitter', {
game_id: currentGameId,
player_out_lineup_id: currentBatterLineupId,
player_in_card_id: selectedBenchPlayerId,
team_id: myTeamId
});
// Handle confirmation
socket.on('substitution_confirmed', (data) => {
console.log('Substitution successful:', data.type, data.new_lineup_id);
showSuccessMessage('Pinch hitter entered the game');
});
// Handle broadcast (all clients receive)
socket.on('player_substituted', (data) => {
console.log('Substitution:', data.type, data.message);
updateLineupDisplay(data.team_id);
addToGameLog(data.message);
// Refresh lineup from server
socket.emit('get_lineup', { game_id: currentGameId, team_id: data.team_id });
});
// Handle errors
socket.on('substitution_error', (data) => {
console.error('Substitution failed:', data.message, data.code);
showErrorMessage(data.message);
// Show user-friendly error based on code
if (data.code === 'NOT_CURRENT_BATTER') {
alert('Can only pinch hit for the current batter');
} else if (data.code === 'PLAYER_ALREADY_OUT') {
alert('This player has already been removed from the game');
}
});
// Receive lineup data
socket.on('lineup_data', (data) => {
const activePlayers = data.players.filter(p => p.is_active);
const benchPlayers = data.players.filter(p => !p.is_active);
renderLineup(activePlayers);
renderBench(benchPlayers);
});
```
