CLAUDE: Update documentation for Phase 3E-Prep completion

**Documentation Updates**:

NEXT_SESSION.md:
- Updated status: Phase 3 now 85% complete (was 80%)
- Added Phase 3E-Prep section documenting GameState refactor
- Updated current context with new approach
- Added Architecture Decision #6: Unified Player References
- Updated Tasks for Next Session to reflect simplified Phase 3E-Main
- Last commit: d560844
- Date: 2025-11-03

**Key Changes Documented**:
1. GameState refactor complete (all player refs now full objects)
2. Foundation ready for Phase 3E-Main (add position ratings)
3. Simplified approach: just add field, load at game start
4. X-Check resolution gets direct access: state.current_batter.position_rating

**Next Steps**: Phase 3E-Main tasks updated to reflect new architecture

### 📍 Current Context
**Phase 3 (Weeks 7-9): X-Check Play System** is 80% complete. We have successfully implemented:
**Phase 3 (Weeks 7-9): X-Check Play System** is 85% complete. We have successfully implemented:
- ✅ **Phase 3A**: X-Check data models (XCheckResult, PositionRating, PlayOutcome.X_CHECK)
- ✅ **Phase 3B**: League config tables (defense tables, error charts, helper functions)
- ✅ **Phase 3C**: Complete X-Check resolution logic in PlayResolver (397 lines, 6 helper methods)
- ✅ **Phase 3D**: X-Check runner advancement tables (690 lines, 59 tests, all passing)
- ✅ **Phase 3E-Prep**: GameState refactor - unified player references (all full objects)
**Next priority**: **Phase 3E - WebSocket Events & UI Integration**. This phase involves integrating X-Check with the WebSocket layer, loading position ratings from the API, implementing Redis caching, and supporting Auto/Manual/Semi-Auto modes with Accept/Reject flows.
**Next priority**: **Phase 3E-Main - Position Ratings & Self-Contained State**. This phase adds position ratings to LineupPlayerState and loads them at game start from the PD API with Redis caching. This makes GameState fully self-contained with everything needed for X-Check resolution.

### Phase 3E-Prep: GameState Refactor (2025-11-03)
**Commit**: `d560844`
**Files Modified**:
- `backend/app/models/game_models.py` - Changed current_batter/pitcher/catcher to full objects
- `backend/app/core/game_engine.py` - Updated _prepare_next_play() to populate full objects
- `backend/app/core/state_manager.py` - Create placeholder batter on game creation
- `tests/unit/models/test_game_models.py` - Updated all 27 GameState tests (all passing)
**Files Created**:
- `.claude/implementation/GAMESTATE_REFACTOR_PLAN.md` - Complete refactor documentation
**Implementation**: Architectural improvement for consistency and Phase 3E readiness
**BEFORE (Inconsistent)**:
```python
# Runners were full objects
on_first: Optional[LineupPlayerState] = None
on_second: Optional[LineupPlayerState] = None
on_third: Optional[LineupPlayerState] = None
# But current players were just IDs
current_batter_lineup_id: int
current_pitcher_lineup_id: Optional[int] = None
current_catcher_lineup_id: Optional[int] = None
```
**AFTER (Consistent)**:
```python
# All player references are now full objects
on_first: Optional[LineupPlayerState] = None
on_second: Optional[LineupPlayerState] = None
on_third: Optional[LineupPlayerState] = None
current_batter: LineupPlayerState
current_pitcher: Optional[LineupPlayerState] = None
current_catcher: Optional[LineupPlayerState] = None
```
**Benefits**:
1. **Consistent API**: All player references use same type (LineupPlayerState objects)
2. **Self-contained State**: GameState has everything needed for resolution
3. **No lookups needed**: Direct access to player data (`state.current_batter.card_id`)
4. **Foundation for Phase 3E-Main**: Easy to add `position_rating` field to objects
**Database Operations**:
- No schema changes needed (Play table still stores IDs)
- IDs extracted from objects when saving: `state.current_batter.lineup_id`
- Maintains referential integrity
**Testing**: All 27 GameState tests passing, no regressions
**Rationale**: Sets foundation for Phase 3E-Main where we'll add position ratings to LineupPlayerState. This refactor makes GameState truly self-contained - everything needed for X-Check resolution will be in the state object.

## Key Architecture Decisions Made
### 1. **X-Check as First-Class PlayOutcome**
@ -258,11 +314,24 @@
- Clean separation of concerns
- **Impact**: Phase 3C complete without blocking on table data
### 6. **Unified Player References in GameState** (Phase 3E-Prep)
- **Decision**: Change current_batter/pitcher/catcher from IDs to full LineupPlayerState objects
- **Rationale**:
- Inconsistency: runners (on_first/second/third) were objects but current players were IDs
- Self-contained state: everything needed for resolution in one place
- Foundation for Phase 3E: easy to add position_rating field to existing objects
- No lookups: direct access to player data without StateManager queries
- **Impact**:
- GameState is now fully self-contained
- No external lookups needed during play resolution
- Clean foundation for adding position ratings
- Database unchanged (IDs extracted when saving)

## Tasks for Next Session
### Phase 3E Focus: WebSocket Events & UI Integration
### Phase 3E-Main Focus: Position Ratings & Self-Contained State
**Simplified Approach**: With Phase 3E-Prep complete, GameState now uses full LineupPlayerState objects. We just need to:
1. Add PositionRating dataclass (if not already exists from Phase 3A)
2. Add `position_rating` field to LineupPlayerState
3. Load ratings at game start and attach to objects
4. X-Check resolution already has access via `state.current_batter.position_rating`
---
### Task 1: Understand Phase 3E Requirements (30 mins)
### Task 1: Create/Verify PositionRating Dataclass (30 mins)
**File(s)**: `@.claude/implementation/phase-3e-websocket-events.md`
**File(s)**: `backend/app/models/player_models.py`
**Goal**: Thoroughly understand the WebSocket integration requirements before implementation.
**Goal**: Ensure PositionRating dataclass exists with all needed fields for X-Check resolution.
**Actions**:
1. Read phase-3e document completely
2. Understand the three modes:
- PD Auto Mode: Auto-resolve with Accept/Reject
- SBA Manual Mode: User selects from legal options
- SBA Semi-Auto Mode: Like PD Auto if ratings provided
3. Understand position rating loading flow (API → Redis cache → PlayResolver)
4. Understand Accept/Reject workflow for auto-resolved plays
5. Review WebSocket event patterns in existing game_handlers.py
**Check If Exists**: Phase 3A may have created this already. Verify fields include:
```python
@dataclass
class PositionRating:
"""Defensive ratings for a player at a specific position."""
position: str # Position code (SS, 3B, LF, etc.)
range: int # Range rating (1-5)
error: int # Error rating (0-88 depending on position)
arm: int # Arm strength (1-5)
speed: Optional[int] = None # Speed rating (0-20) for SPD tests
```
**Test Command**: N/A (reading/understanding task)
**Test Command**:
```bash
pytest tests/unit/models/test_player_models.py -v -k PositionRating
```
**Acceptance Criteria**:
- [ ] Understand all three X-Check modes (Auto, Manual, Semi-Auto)
- [ ] Clear on position rating source (PD API)
- [ ] Clear on Redis caching strategy
- [ ] Clear on Accept/Reject event flow
- [ ] Clear on override logging requirements
- [ ] PositionRating dataclass exists with all fields
- [ ] Tests exist for PositionRating
- [ ] Documented in player_models.py

### Task 2: Create PD API Client for Position Ratings (1-2 hours)
### Task 2: Add position_rating Field to LineupPlayerState (30 mins)
**File(s)**: `backend/app/models/game_models.py`
**Goal**: Add position_rating field to LineupPlayerState so ratings can be attached at game start.
**Changes**:
```python
class LineupPlayerState(BaseModel):
lineup_id: int
card_id: int
position: str
batting_order: Optional[int] = None
is_active: bool = True
# NEW: Position rating (loaded at game start for PD league)
position_rating: Optional[PositionRating] = None
```
**Test Command**:
```bash
pytest tests/unit/models/test_game_models.py::TestLineupPlayerState -v
```
**Acceptance Criteria**:
- [ ] position_rating field added
- [ ] Optional (SBA won't have ratings)
- [ ] Tests updated
- [ ] No breaking changes to existing tests
