The outs_before field in play records was incorrectly storing the
outs count AFTER _apply_play_result() modified state.outs, rather
than the value before the play resolved.
Fix: Capture state.outs before calling _apply_play_result() and
pass it explicitly to _save_play_to_db() as a required parameter.

When recovering game state after reconnect/refresh, the old code:
1. Only looked at the last play overall (regardless of team)
2. Used that play's batting order for the currently batting team
3. Reset the non-batting team's index to 0
This caused the wrong batter to appear after inning changes - e.g.,
batter #1 showing instead of #5 in top of 2nd after bottom of 1st ended.
Fix: Now recovers each team's batter index separately by filtering
plays by half ("top" = away team, "bottom" = home team) and finding
each team's last at-bat independently.

After changing runners_advanced from list[tuple] to list[RunnerAdvancementData],
three locations were still trying to unpack as tuples causing "cannot unpack
non-iterable RunnerAdvancementData object" error on triples/doubles with runners.
Fixed locations:
- app/core/game_engine.py:772 - _apply_play_result() advancement map
- app/core/game_engine.py:1081 - _save_play() finals lookup
- terminal_client/display.py:150 - Runner movement display
Also renamed refactor_overview.md to game-engine-play-tracking-design.md
for clarity and updated the example code to use dataclass access pattern.

Root cause: WebSocket handler had stale state reference after
resolve_manual_play() completed. The handler's state object still had
the old batter index, and calling state_manager.update_state()
overwrote the game engine's updated state.
Fix: Re-fetch state from state_manager AFTER resolve_manual_play()
returns, ensuring we get the state with the advanced batter index.
Also improved logging in _prepare_next_play() to show batting_order
for easier debugging.

Two related bug fixes for gameplay accuracy:
**Backend - play_resolver.py**:
- Fixed DOUBLE2 advancement: Runners now advance exactly 2 bases
* 1st → 3rd, 2nd → home, 3rd → home
* Was incorrectly advancing all runners to home
- Fixed DOUBLE3 advancement: Runners now advance exactly 3 bases
* All runners score (1st+3=4, 2nd+3=5→4, 3rd+3=6→4)
* Updated docstrings for clarity
**Frontend - ManualOutcomeEntry.vue**:
- Fixed hit location requirement logic
* Now requires hit location when runners on base (any outs)
* Was incorrectly restricting to only when outs < 2
* Hit location determines runner advancement regardless of outs
These fixes ensure accurate Strat-O-Matic gameplay simulation.

This commit fixes two critical bugs in the game engine and updates tests
to match current webhook behavior:
1. State Recovery - Batter Advancement (operations.py:545-546)
- Added missing batting_order and outs_recorded fields to plays dictionary
- These fields exist in database but weren't loaded by load_game_state()
- Root cause: Batter index was correctly recovered but current_batter remained
at placeholder (batting_order=1) because recovery logic couldn't find the
actual batting_order from last play
- Fix enables proper batter advancement after backend restarts
2. Flyball Descriptions - 2 Outs Logic (runner_advancement.py)
- Made flyball descriptions dynamic based on outs and actual base runners
- FLYOUT_A (Deep): Lines 1352-1363
- FLYOUT_B (Medium): Lines 1438-1449
- FLYOUT_BQ (Medium-shallow): Lines 1521-1530
- With 2 outs: "3rd out, inning over" (no advancement possible)
- With 0-1 outs: Dynamic based on runners ("R3 scores" only if R3 exists)
- Game logic was already correct (runs_scored=0), only descriptions were wrong
- Fixed method signatures to include hit_location parameter for all flyball methods
- Updated X-check function calls to pass hit_location parameter
3. Test Updates
- Fixed test expectation in test_flyball_advancement.py to match corrected behavior
- Descriptions now only show runners that actually exist (no phantom "R2 DECIDE")
- Auto-fixed import ordering with Ruff
- Updated websocket tests to match current webhook behavior:
* test_submit_manual_outcome_success now expects 2 broadcasts (play_resolved + game_state_update)
* test_submit_manual_outcome_missing_required_location updated to reflect hit_location now optional
Testing:
- All 739 unit tests passing (100%)
- Verified batter advances correctly after state recovery
- Verified flyball with 2 outs shows correct description
- Verified dynamic descriptions only mention actual runners on base
- Verified websocket handler broadcasts work correctly

- resolve_manual_play reduced from ~135 lines to ~60 lines
- Single source of truth for: roll tracking, state capture, transaction
handling, inning advance, cleanup, and state updates
Benefits:
- Changes to play finalization only need to be made in one place
- Reduced risk of divergent behavior between resolution modes
- Better testability and maintainability

Issue #4 from code review - multi-step database operations were not
wrapped in transactions, risking partial state on failure.
Changes:
- Modified save_play() and update_game_state() in DatabaseOperations
to accept optional session parameter for transaction grouping
- Wrapped resolve_play() DB operations in single atomic transaction
- Wrapped resolve_manual_play() DB operations in single atomic transaction
- Transaction commits atomically or rolls back entirely on failure
Pattern: When session provided, use flush() for IDs without committing;
caller controls transaction. When no session, create internal transaction.

- lineup_id (was 'id'), card_id fields
- player.headshot for UI circles
- Optional fields for event variations
- CurrentSituation.vue: Adapt to updated type structure
- Substitution selectors: Use updated Lineup type fields
This fixes the issue where pitcher badge wouldn't show after game recovery

Added ability to test X-Check defensive plays directly in the terminal
client using the resolve_with command. This allows testing the complete
X-Check resolution system (defense tables, error charts, runner advancement)
with actual player ratings.
Changes:
- repl.py: Updated do_resolve_with() to parse "x-check <position>" syntax
- Accepts "x-check", "xcheck", or "x_check" followed by position
- Validates position (P, C, 1B, 2B, 3B, SS, LF, CF, RF)
- Passes xcheck_position parameter through to commands
- commands.py: Updated resolve_play() to accept xcheck_position parameter
- Passes xcheck_position to game_engine.resolve_play()
- Shows "🎯 Forcing X-Check to: <position>" message
- game_engine.py: Updated resolve_play() to accept xcheck_position parameter
- For X_CHECK outcomes, uses xcheck_position as hit_location
- Enables full X-Check resolution with defense tables and error charts
- help_text.py: Updated resolve_with help documentation
- Added x-check usage syntax and examples
- Documented position parameter requirement
- Added note about using actual player ratings
Usage:
⚾ > defensive
⚾ > offensive
⚾ > resolve_with x-check SS # Test X-Check to shortstop
⚾ > resolve_with x-check LF # Test X-Check to left field
This integrates the existing play_resolver._resolve_x_check() logic,

Complete integration of position ratings system enabling X-Check defensive plays
to use actual player ratings from PD API with intelligent fallbacks for SBA.
**Live API Testing Verified**: ✅
- Endpoint: GET https://pd.manticorum.com/api/v2/cardpositions?player_id=8807
- Response: 200 OK, 7 positions retrieved successfully
- Cache performance: 16,601x faster (API: 0.214s, Cache: 0.000s)
- Data quality: Real defensive ratings (range 1-5, error 0-88)
**Architecture Overview**:
- League-aware: PD league fetches ratings from API, SBA uses defaults
- StateManager integration: Defenders retrieved from lineup cache
- Self-contained GameState: All data needed for X-Check in memory
- Graceful degradation: Falls back to league averages if ratings unavailable
**Files Created**:
1. app/services/pd_api_client.py (NEW)
- PdApiClient class for PD API integration
- Endpoint: GET /api/v2/cardpositions?player_id={id}&position={pos}
- Async HTTP client using httpx (already in requirements.txt)
- Optional position filtering: get_position_ratings(8807, ['SS', '2B'])
- Returns List[PositionRating] for all positions player can play
- Handles both list and dict response formats
- Comprehensive error handling with logging
2. app/services/position_rating_service.py (NEW)
- PositionRatingService with in-memory caching
- get_ratings_for_card(card_id, league_id) - All positions
- get_rating_for_position(card_id, position, league_id) - Specific position

**Files Modified**:
1. app/models/game_models.py
- LineupPlayerState: Added position_rating field (Optional[PositionRating])
- GameState: Added get_defender_for_position(position, state_manager)
- Uses StateManager's lineup cache to find active defender by position
- Iterates through lineup.players to match position + is_active
2. app/config/league_configs.py
- SbaConfig: Added supports_position_ratings() → False
- PdConfig: Added supports_position_ratings() → True
- Enables league-specific behavior without hardcoded conditionals
3. app/core/play_resolver.py
- __init__: Added state_manager parameter for X-Check defender lookup
- _resolve_x_check(): Replaced placeholder defender ratings with actual lookup
- Uses league config to check if ratings supported
- Fetches defender via state.get_defender_for_position()
- Falls back to defaults (range=3, error=15) if ratings unavailable
- Detailed logging for debugging rating lookups
4. app/core/game_engine.py
- Added _load_position_ratings_for_lineup() method
- Loads all position ratings at game start for PD league
- Skips loading for SBA (league config check)
- start_game(): Calls rating loader for both teams before marking active
- PlayResolver instantiation: Now passes state_manager parameter
- Logs: "Loaded X/9 position ratings for team Y"
**X-Check Resolution Flow**:
1. League check: config.supports_position_ratings()?
2. Get defender: state.get_defender_for_position(pos, state_manager)
3. If PD + defender.position_rating exists: Use actual range/error
4. Else if defender found: Use defaults (range=3, error=15)
5. Else: Log warning, use defaults
**Position Rating Loading (Game Start)**:
1. Check if league supports ratings (PD only)
2. Get lineup from StateManager cache
3. For each player:
- Fetch rating from position_rating_service (with caching)
- Set player.position_rating field
4. Cache API responses (16,000x faster on subsequent access)
5. Log success: "Loaded X/9 position ratings for team Y"
**Live Test Results (Player 8807)**:
```
Position Range Error Innings
CF 3 2 372
2B 3 8 212
SS 4 12 159
RF 2 2 74
LF 3 2 62
1B 4 0 46
3B 3 65 34
```

- Updated x_check_f1/f2/f3 signatures to accept GameState and hit_location
- Implemented delegation logic: error cases use simple tables, non-error
cases delegate to existing tested result handlers (_execute_result,
_fb_result_*)
- Updated PlayResolver._get_x_check_advancement() to pass new parameters
- Updated all tests to provide required GameState fixtures
Benefits:
- Reuses 13 existing groundball + 4 flyball result handlers (DRY)
- No DP probability needed - X-Check d20 already tested defender
- Full game context: real lineup IDs, outs count, conditional logic
- Error cases remain simple and efficient
Test Results: 264/265 core tests passing (1 pre-existing dice failure)

Fixed incorrect double play logic that was rolling for probability
twice - once for the chart result and again for execution.
Changes:
- Removed _calculate_double_play_probability() method entirely
- Updated _gb_result_2() to execute DP deterministically
- Updated _gb_result_10() to execute DP deterministically
- Updated _gb_result_13() to execute DP deterministically
- Removed TestDoublePlayProbability test class (5 tests)
- Updated DP tests to reflect deterministic behavior
Logic: Chart already determines outcome via dice roll. When chart
says "Result 2: Double Play", the DP happens (if <2 outs and runner
on 1st exists). No additional probability roll needed.
Tests: 55/55 runner advancement tests passing

Fixed two critical bugs in Phase 3D X-Check implementation plus
improved dice audit trail for better tracking.
BUG #1: on_base_code Mapping Error (Sequential vs Bit Field)
============================================================
The implementation incorrectly treated on_base_code as a bit field
when it is actually a sequential lookup mapping.
WRONG (bit field):
Code 3 (0b011) → R1 + R2
Code 4 (0b100) → R3 only
CORRECT (sequential):
Code 3 → R3 only
Code 4 → R1 + R2
Fixed:
- build_advancement_from_code() decoder (sequential mapping)
- build_flyball_advancement_with_error() decoder (sequential mapping)
- 13 test on_base_code values (3↔4 corrections)
- Updated documentation to clarify NOT a bit field
BUG #2: Table Data Not Matching Official Charts
================================================
7 table entries in G1_ADVANCEMENT_TABLE and G2_ADVANCEMENT_TABLE
did not match the official rulebook charts provided by user.
Fixed table entries:
- G1 Code 1, Infield In: Changed Result 3 → 2
- G1 Code 3, Normal: Changed Result 13 → 3
- G1 Code 3, Infield In: Changed Result 3 → 1
- G1 Code 4, Normal: Changed Result 3 → 13
- G1 Code 4, Infield In: Changed Result 4 → 2
- G2 Code 3, Infield In: Changed Result 3 → 1
- G2 Code 4, Normal: Changed Result 5 → 4
Also fixed 7 test expectations to match corrected tables.
IMPROVEMENT: Better Dice Audit Trail
=====================================
Updated _resolve_x_check() in PlayResolver to use proper
dice_system.roll_fielding() instead of manual die rolling.
Benefits:
- All dice tracked in audit trail (roll_id, timestamp, position)
- Automatic error_total calculation (no manual 3d6 addition)
- Consistent with codebase patterns
- Position recorded for historical analysis
Testing:
- All 59 X-Check advancement tests passing (100%)
- All 9 PlayResolver tests passing (100%)
- All table entries validated against official charts
- Complete codebase scan: no bit field operations found

reconstructs game state by replaying remaining plays.
Database Operations (app/database/operations.py):
- delete_plays_after(): Delete plays with play_number > target
- delete_substitutions_after(): Delete lineup entries with after_play >= target
- delete_rolls_after(): Delete dice rolls (kept for reference, not used)
Game Engine (app/core/game_engine.py):
- rollback_plays(): Main rollback orchestration
- Validates: num_plays > 0, enough plays exist, game not completed
- Deletes plays and substitutions from database
- Clears in-memory roll tracking
- Calls state_manager.recover_game() to rebuild state
- Returns updated GameState
Terminal Client (terminal_client/commands.py, terminal_client/repl.py):
- rollback_plays(): Command wrapper with user-friendly output
- do_rollback(): REPL command with argument parsing
Usage:
⚾ > rollback 3
Validations:
- Cannot roll back more plays than exist
