## Actual Implementation Patterns
### Forward-Looking Snapshot Pattern (Refactored 2025-10-25)
The GameEngine uses a sophisticated snapshot-before-execution pattern:
#### Problem Solved
Original approach had database lookbacks during play saving, causing:
- Multiple redundant database queries per play
- Inconsistent snapshots if lineup changes during play
- Difficult to reason about "state at time of play"
#### Solution: `_prepare_next_play()`
Before each play execution, we prepare a complete snapshot:
```python
async def _prepare_next_play(self, state: GameState) -> None:
"""Prepare snapshot for the next play."""
# 1. Determine and advance batting order index
if state.half == "top":
current_idx = state.away_team_batter_idx
state.away_team_batter_idx = (current_idx + 1) % 9
batting_team = state.away_team_id
fielding_team = state.home_team_id
else:
current_idx = state.home_team_batter_idx
state.home_team_batter_idx = (current_idx + 1) % 9
batting_team = state.home_team_id
fielding_team = state.away_team_id
# 2. Fetch lineups from database
batting_lineup = await self.db_ops.get_active_lineup(state.game_id, batting_team)
fielding_lineup = await self.db_ops.get_active_lineup(state.game_id, fielding_team)
# 3. Set snapshot fields
state.current_batter_lineup_id = batting_order[current_idx].id
state.current_pitcher_lineup_id = pitcher.id
state.current_catcher_lineup_id = catcher.id
# 4. Calculate on_base_code (bit field: 1=1st, 2=2nd, 4=3rd)
state.current_on_base_code = 0
for runner in state.runners:
if runner.on_base == 1: state.current_on_base_code |= 1
elif runner.on_base == 2: state.current_on_base_code |= 2
elif runner.on_base == 3: state.current_on_base_code |= 4
```
#### Benefits
- **Single Truth**: Snapshot captured once, used throughout play
- **No Lookbacks**: `_save_play_to_db()` just reads snapshot fields
- **Consistent**: State cannot change between snapshot and save
- **Independent Batting Orders**: Each team tracks their own `batter_idx`
- **Bit Field Optimization**: `on_base_code` enables efficient database queries
### Play Execution Sequence
The `resolve_play()` method follows explicit orchestration:
```python
async def resolve_play(self, game_id: UUID) -> PlayResult:
# STEP 1: Resolve play (dice roll + outcome determination)
result = play_resolver.resolve_play(state, defensive_decision, offensive_decision)
# STEP 2: Save play to DB (uses snapshot from GameState)
await self._save_play_to_db(state, result)
# STEP 3: Apply result to state (outs, score, runners)
self._apply_play_result(state, result)
# STEP 4: Update game state in DB
await self.db_ops.update_game_state(...)
# STEP 5: Check for inning change
if state.outs >= 3:
await self._advance_inning(state, game_id)
await self.db_ops.update_game_state(...) # Update again after inning change
await self._batch_save_inning_rolls(game_id)
# STEP 6: Prepare next play (always last step)
if state.status == "active":
await self._prepare_next_play(state)
```
### Advanced Dice System (AbRoll)
Instead of simple d20 rolls, we use a structured roll system:
**Roll Types** (`roll_types.py`):
- `CheckRoll`: Initial d20 check (1=wild pitch, 2=passed ball, 3-20=normal)
- `ResolutionRoll`: Secondary d20 for confirming special events or determining specifics
- `AbRoll`: Complete at-bat roll combining check + resolution + context
**Context Tracking**:
```python
@dataclass
class AbRoll:
check_roll: CheckRoll
resolution_roll: Optional[ResolutionRoll]
game_id: UUID
inning: int
half: str
play_number: int
# ... full audit trail
```
**Batch Persistence**:
- Rolls accumulated in memory during half-inning
- `_batch_save_inning_rolls()` saves all at inning boundary
- Reduces database writes from N (per play) to 1 (per half-inning)
### Lineup Validation Strategy
**At Game Start** (Strict):
- Both teams' lineups validated (minimum 9 players)
- Both teams' defensive positions validated
- Exception: This is the only time we validate BOTH teams
**At Inning Change** (Defensive Only):
- Only defensive team's positions validated
- Allows offensive substitutions without validation delay
- Rationale: Offensive lineup can be incomplete mid-game (pinch hitter scenarios)
**Validation Rules**:
- Must have exactly one: P, C, 1B, 2B, 3B, SS, LF, CF, RF
- DH is optional (not validated as required)

- [ ] Play resolution completes in <200ms - ✅ Play resolution completes in <200ms (fast in-memory operations)
### Test Coverage Summary
- **Unit Tests**: 54 tests covering dice, roll types, play resolution, and validation
- **Integration Tests**: 7 test classes covering complete game flows (requires database)
- **Manual Test Script**: 5 comprehensive test scenarios for manual validation
## Enhancements Beyond Plan
### 1. Advanced Dice System (AbRoll)
The implemented dice system is more sophisticated than planned:
- **Structured Roll Types**: `AbRoll`, `CheckRoll`, `ResolutionRoll` dataclasses
- **Context Tracking**: Each roll knows its game_id, inning, play_number
- **Batch Persistence**: Rolls saved at inning boundaries instead of per-play
- **Wild Pitch/Passed Ball**: Special roll detection on check_d20 == 1 or 2
### 2. Forward-Looking Snapshot Pattern (Refactor 2025-10-25)
The GameEngine uses a sophisticated snapshot pattern:
- **Prepare Before Execute**: `_prepare_next_play()` sets snapshot fields before play resolution
- **Independent Batting Orders**: `away_team_batter_idx` and `home_team_batter_idx` track separately
- **Lineup Validation**: At game start and inning changes, defensive positions validated
- **On-Base Code**: Bit field (1=1st, 2=2nd, 4=3rd) calculated from runners
### 3. Database-Driven Lineup Management
Unlike the simple placeholder approach in the plan:
- Lineups fetched from database via `get_active_lineup()`
- Snapshot fields reference actual lineup IDs from database
- Supports future substitution tracking
## Test Implementation Details (2025-10-25)
### test_play_resolver.py (18 tests)
**Coverage**:
- `TestSimplifiedResultChart` (12 tests): All outcome ranges (strikeout, groundout, flyout, walk, single, double, triple, homerun) + wild pitch/passed ball confirmation logic
- `TestPlayResultResolution` (5 tests): Outcome resolution with runner advancement (walk, single, homerun, wild pitch scenarios)
- `TestPlayResolverSingleton` (1 test): Singleton pattern validation
**Key Insights**:
- Tests use mock `AbRoll` objects with simplified constructor (no CheckRoll/ResolutionRoll sub-objects)
- Wild pitch/passed ball confirmation tested (check_d20 triggers, resolution_d20 confirms)
- Runner advancement logic validated for bases loaded, scoring from third, grand slams
### test_validators.py (36 tests)
**Coverage**:
- `TestGameStateValidation` (3 tests): Active/pending/completed state checks
- `TestOutsValidation` (3 tests): Valid range (0-2), negative, too high
- `TestInningValidation` (5 tests): Valid innings, zero/negative, invalid half values
- `TestDefensiveDecisionValidation` (5 tests): Valid decisions, Pydantic validation of alignment/depth, hold runner logic
- `TestOffensiveDecisionValidation` (6 tests): Valid decisions, Pydantic validation of approach, steal validation, bunt with 2 outs rule
- `TestLineupValidation` (5 tests): Complete lineup, missing positions, duplicates, inactive players, DH optional
- `TestGameFlowValidation` (8 tests): Inning continuation, game over conditions (9th inning, extras, tied games)
- `TestGameValidatorSingleton` (1 test): Singleton pattern validation
**Key Insights**:
- Discovered that Pydantic validates at model creation, not assignment (unless `validate_assignment=True`)
- Tests properly simulate `state.outs += 1` (goes to 3 temporarily) to match GameEngine flow
- Confirmed lineup validation enforces exactly one active player per required position (P, C, 1B, 2B, 3B, SS, LF, CF, RF)
### test_game_engine.py (7 test classes)
**Coverage**:
- `TestSingleAtBat`: Complete at-bat flow (create → start → decisions → resolve)
- `TestFullInning`: Play until 3 outs, verify inning advancement
- `TestLineupValidation`: Fail cases (no lineups, incomplete, missing positions)
- `TestSnapshotTracking`: Verify snapshot fields populated, on_base_code calculation
- `TestBattingOrderCycling`: Independent batting order per team, wraparound at 9
- `TestGameCompletion`: Game status changes to completed at end
**Key Insights**:
- All tests require database access (marked with `@pytest.mark.integration`)
- Tests create full lineups (9 players per team) for realistic scenarios
- Validates forward-looking snapshot pattern works end-to-end
## Week 5 Status: ✅ COMPLETE
**Completion Date**: 2025-10-25
All deliverables achieved:
- ✅ Code implementation (dice, play_resolver, validators, game_engine)
