72a3b94ce7 CLAUDE: Add transaction handling for multi-step DB operations
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.

All 739 unit tests passing.

1a562a75d2 CLAUDE: Fix pitcher/catcher recovery and lineup data format
Backend fixes:
- state_manager: Properly recover current_pitcher and current_catcher from
  fielding team during game state recovery (fixes pitcher badge not showing)
- handlers: Add headshot field to lineup data, use lineup_service for proper
  player data loading on cache miss
- lineup_service: Minor adjustments for headshot support

Frontend fixes:
- player.ts: Update Lineup type to match WebSocket event format
  - 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
because current_pitcher was being set from batting team instead of fielding team.

b15f80310b CLAUDE: Add LineupService and SBA API client for player data integration
Created centralized services for SBA player data fetching at lineup creation:

Backend - New Services:
- app/services/sba_api_client.py: REST client for SBA API (api.sba.manticorum.com)
  with batch player fetching and caching support
- app/services/lineup_service.py: High-level service combining DB operations
  with API calls for complete lineup entries with player data

Backend - Refactored Components:
- app/core/game_engine.py: Replaced raw API calls with LineupService,
  reduced _prepare_next_play() from ~50 lines to ~15 lines
- app/core/substitution_manager.py: Updated pinch_hit(), defensive_replace(),
  change_pitcher() to use lineup_service.get_sba_player_data()
- app/models/game_models.py: Added player_name/player_image to LineupPlayerState
- app/services/__init__.py: Exported new LineupService components
- app/websocket/handlers.py: Enhanced lineup state handling

Frontend - SBA League:
- components/Game/CurrentSituation.vue: Restored player images with fallback
  badges (P/B letters) for both mobile and desktop layouts
- components/Game/GameBoard.vue: Enhanced game board visualization
- composables/useGameActions.ts: Updated game action handling
- composables/useWebSocket.ts: Improved WebSocket state management
- pages/games/[id].vue: Enhanced game page with better state handling
- types/game.ts: Updated type definitions
- types/websocket.ts: Added WebSocket type support

Architecture Improvement:
All SBA player data fetching now goes through LineupService:
- Lineup creation: add_sba_player_to_lineup()
- Lineup loading: load_team_lineup_with_player_data()
- Substitutions: get_sba_player_data()

All 739 unit tests pass.

b0d79ef7ef CLAUDE: Fix squeeze_bunt validation - remove bases loaded restriction
Removed the incorrect restriction that squeeze bunt cannot be used with bases
loaded. The only requirements for squeeze bunt are:
- Runner on third base
- Not with 2 outs

Updated validator and test to reflect correct rule.

Test results: 739/739 passing (100%)

e165b449f5 CLAUDE: Refactor offensive decisions - replace approach with action field
Backend refactor complete - removed all deprecated parameters and replaced
with clean action-based system.

Changes:
- OffensiveDecision model: Added 'action' field (6 choices), removed
  deprecated 'hit_and_run' and 'bunt_attempt' boolean fields
- Validators: Added action-specific validation (squeeze_bunt, check_jump,
  sac_bunt, hit_and_run situational constraints)
- WebSocket handler: Updated submit_offensive_decision to use action field
- Terminal client: Updated CLI, REPL, arg parser, and display for actions
- Tests: Updated all 739 unit tests (100% passing)

Action field values:
- swing_away (default)
- steal (requires steal_attempts parameter)
- check_jump (requires runner on base)
- hit_and_run (requires runner on base)
- sac_bunt (cannot use with 2 outs)
- squeeze_bunt (requires R3, not with bases loaded, not with 2 outs)

Breaking changes:
- Removed: hit_and_run boolean → use action="hit_and_run"
- Removed: bunt_attempt boolean → use action="sac_bunt" or "squeeze_bunt"
- Removed: approach field → use action field

Files modified:
- app/models/game_models.py
- app/core/validators.py
- app/websocket/handlers.py
- terminal_client/main.py

63bffbc23d CLAUDE: Session 1 cleanup complete - Parts 4-6
Completed remaining Session 1 work:

Part 4: Remove offensive approach field
- Removed `approach` field from OffensiveDecision model
- Removed approach validation and validator
- Updated 7 backend files (model, tests, handlers, AI, validators, display)

Part 5: Server-side depth validation
- Added walk-off validation for shallow outfield (home batting, 9th+, close game, runners)
- Updated outfield depths from ["in", "normal"] to ["normal", "shallow"]
- Infield validation already complete (corners_in/infield_in require R3)
- Added comprehensive test coverage

Part 6: Client-side smart filtering
- Updated DefensiveSetup.vue with dynamic option filtering

- Outfield options: only show shallow in walk-off scenarios
- Hybrid validation (server authority + client UX)

Total Session 1: 25 files modified across 6 parts
- Removed unused config fields
- Fixed hit location requirements
- Removed alignment/approach fields
- Added complete depth validation

All backend tests passing (730/731 - 1 pre-existing failure)

197d91edfb CLAUDE: Remove defensive alignment field completely
Removed the unused alignment field from DefensiveDecision model and all
related code across backend and frontend.

Backend changes:
- models/game_models.py: Removed alignment field and validator
- terminal_client/display.py: Removed alignment from display
- core/ai_opponent.py: Updated log message
- tests/unit/models/test_game_models.py: Removed alignment tests
- tests/unit/core/test_validators.py: Removed alignment validation test

Frontend changes:
- types/game.ts: Removed alignment from DefensiveDecision interface
- components/Decisions/DefensiveSetup.vue:
  * Removed alignment section from template
  * Removed alignment from localSetup initialization
  * Removed alignmentOptions array
  * Removed alignmentDisplay computed property
  * Removed alignment from hasChanges comparison
  * Removed alignment from visual preview (reorganized to col-span-2)

Rationale: Defensive alignment is not active in the game and will not be
used. Per Cal's decision, remove completely rather than keep as dead code.

Tests: All 728 backend unit tests passing (100%)

Session 1 Part 3 - Change #6 complete
Part of cleanup work from demo review

c705e87ee2 CLAUDE: Fix test_resolve_play_success unit test
Fixed failing test caught by pre-commit hook. The test was not properly
mocking dependencies in the resolve_play command.

Changes:
- Added mock for state_manager.get_state() to return valid state
- Added mock for random.choice() to return deterministic PlayOutcome
- Updated assertion to expect auto-generated outcome (SINGLE_1)
- Test now properly validates the auto-outcome behavior for terminal testing

Root cause: resolve_play() checks state_manager early and auto-generates
a random outcome for testing when no forced outcome is provided. Test was
not accounting for either behavior.

All 731 unit tests now passing (100%).

e147ab17f1 CLAUDE: Phase 3F - Substitution System WebSocket Events
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):

76e01420a3 CLAUDE: Fix DO3 (double-3) batter advancement
Fixed incorrect batter advancement for DO3 (double-3) outcomes. The batter
was incorrectly reaching 3B instead of 2B.

DO3 means:
- DO = Double (batter reaches 2B)
- 3 = Runners advance 3 bases

Changes:
- play_resolver.py: Fixed DOUBLE_3 outcome handling (line 416)
  - Changed batter_result from 3 to 2
  - Updated description to clarify "runners advance 3 bases" not "batter to 3rd"

- play_resolver.py: Fixed X-Check DO3 handling (line 1043)
  - Changed batter_reaches from 3 to 2
  - Added comment explaining DO3 notation

Now on a DO3 + NO error:
 Batter reaches 2B (correct)
 R1 advances 3 bases → HOME (correct)
 R2 would advance 3 bases → HOME (correct)
 R3 would advance 3 bases → HOME (correct)

cf7cc23f45 CLAUDE: Fix runner_advancement for new GameState structure
Updated runner_advancement.py and its tests to use the new GameState
structure where current_batter is a LineupPlayerState object instead of
an integer ID.

Changes:
- runner_advancement.py: Replaced all 17 references to
  state.current_batter_lineup_id with state.current_batter.lineup_id

- tests/unit/core/test_runner_advancement.py: Updated test fixtures
  - Mock fixture: Added mock_batter object with lineup_id attribute
  - GameState constructor calls: Create LineupPlayerState objects instead
    of using current_batter_lineup_id parameter (9 tests fixed)

All 34 runner advancement tests now passing. This fixes the AttributeError
that was preventing X-Check resolution from completing in the terminal
client ("'GameState' object has no attribute 'current_batter_lineup_id'").

bb78de2b84 CLAUDE: Add X-Check testing to resolve_with command
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,
providing a way to test the complete X-Check system including defense
range adjustments, table lookups, SPD tests, G2#/G3# conversion, error
charts, and runner advancement.

e6bd66ee39 CLAUDE: Fix game recovery for new GameState structure
Fixed state_manager._rebuild_state_from_data to provide required
current_batter field when recovering games from database. The GameState
model now requires current_batter as a LineupPlayerState object, but
recovery was not populating this field, causing validation errors.

Changes:
- state_manager.py: Create placeholder current_batter during recovery
  - Build LineupPlayerState from first active batter (batting_order=1)
  - Fallback to first available lineup if no #1 batter found
  - Raise error if no lineups exist (invalid game state)
  - _prepare_next_play() will correct the batter after recovery
  - Moved get_lineup_player helper to top of method (removed duplicate)

- tests/unit/core/test_state_manager.py: Update test to use new structure
  - test_update_state_nonexistent_raises_error: Create LineupPlayerState
    instead of using old current_batter_lineup_id field

All 26 state_manager unit tests passing. Game recovery now works
correctly in terminal client - fixes "current_batter Field required"
validation error when running status command on recovered games.

440adf2c26 CLAUDE: Update REPL for new GameState and standardize UV commands
Updated terminal client REPL to work with refactored GameState structure
where current_batter/pitcher/catcher are now LineupPlayerState objects
instead of integer IDs. Also standardized all documentation to properly
show 'uv run' prefixes for Python commands.

REPL Updates:
- terminal_client/display.py: Access lineup_id from LineupPlayerState objects
- terminal_client/repl.py: Fix typos (self.current_game → self.current_game_id)
- tests/unit/terminal_client/test_commands.py: Create proper LineupPlayerState
  objects in test fixtures (2 tests fixed, all 105 terminal client tests passing)

Documentation Updates (100+ command examples):
- CLAUDE.md: Updated pytest examples to use 'uv run' prefix
- terminal_client/CLAUDE.md: Updated ~40 command examples
- tests/CLAUDE.md: Updated all test commands (unit, integration, debugging)
- app/*/CLAUDE.md: Updated test and server startup commands (5 files)

All Python commands now consistently use 'uv run' prefix to align with
project's UV migration, improving developer experience and preventing
confusion about virtual environment activation.

9a9018aab4 CLAUDE: Migrate backend to UV package management
Migrated from pip to UV (v0.9.7) for faster, more reliable package management.

## Changes

### Package Management
- Created `pyproject.toml` with project metadata and dependencies
- Generated `uv.lock` for reproducible builds (198KB)
- Migrated all dependencies from requirements.txt:
  - Production: 20 packages (FastAPI, SQLAlchemy, Pydantic, etc.)
  - Development: 6 packages (pytest, black, mypy, flake8)
- Virtual environment moved from `venv/` to `.venv/` (UV default)

### Dockerfile Updates
- Updated base image: python:3.11-slim → python:3.13-slim
- Added UV installation via official image copy
- Development stage: Uses `uv sync --frozen` for all deps
- Production stage: Uses `uv sync --frozen --no-dev` for prod only
- Commands now use `uv run` prefix for auto-activation
- Set UV environment variables:
  - UV_LINK_MODE=copy (for Docker compatibility)
  - UV_COMPILE_BYTECODE=1 (performance)
  - UV_PYTHON_DOWNLOADS=never (use system Python)

### Code Fixes
- Fixed Pydantic model circular import in `app/models/game_models.py`
  - Added runtime import of PositionRating at end of file
  - Called `model_rebuild()` on LineupPlayerState and GameState
  - Resolves "not fully defined" errors in tests

### Documentation
- Updated `backend/CLAUDE.md` with UV usage:
  - Package management section with UV commands
  - Updated all code examples to use `uv run`
  - Daily development workflow now uses UV
  - Added dependency management guide (add/remove/update)
  - Updated virtual environment location (.venv/)

### Project Files
- Added `.python-version` (3.13) for UV Python version tracking
- Removed UV template files (main.py, README.md)
- Kept existing .gitignore (already includes venv/ and .venv/)

## Testing
-  All imports work correctly
-  55/55 game model tests passing
-  500+ unit tests passing (same as before migration)
-  Test failures are pre-existing (not UV-related)

## Benefits
- 10-100x faster dependency resolution
- 2-3x faster installation
- Better dependency conflict resolution
- Single tool for everything (replaces pip, pip-tools, virtualenv)
- Reproducible builds with uv.lock

## Migration Path for Team
```bash
# One-time: Install UV
curl -LsSf https://astral.sh/uv/install.sh | sh

# In project
cd backend
uv sync  # Creates .venv and installs everything

# Daily usage
uv run python -m app.main
uv run pytest tests/ -v
```

   - 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

   - get_rating_for_position(card_id, position, league_id) - Specific position
   - Cache performance: >16,000x faster on hits
   - Singleton pattern: position_rating_service instance
   - TODO Phase 3E-Final: Upgrade to Redis

3. app/services/__init__.py (NEW)
   - Package exports for clean imports

4. test_pd_api_live.py (NEW)
   - Live API integration test script
   - Tests with real PD player 8807 (7 positions)
   - Verifies caching, filtering, GameState integration
   - Run: `python test_pd_api_live.py`

5. test_pd_api_mock.py (NEW)
   - Mock integration test for CI/CD
   - Demonstrates flow without API dependency

6. tests/integration/test_position_ratings_api.py (NEW)
   - Pytest integration test suite
   - Real API tests with player 8807
   - Cache verification, SBA skip logic
   - Full end-to-end GameState flow

**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
```

**Testing**:
-  Live API: Player 8807 → 7 positions retrieved successfully
-  Caching: 16,601x performance improvement
-  League config: SBA=False, PD=True
-  GameState integration: Defender lookup working
-  Existing tests: 27/28 config tests passing (1 pre-existing URL failure)
-  Syntax validation: All files compile successfully

**Benefits**:
-  X-Check now uses real defensive ratings in PD league
-  SBA league continues working with manual entry (uses defaults)
-  No breaking changes to existing functionality
-  Graceful degradation if API unavailable
-  In-memory caching reduces API calls by >99%
-  League-agnostic design via config system
-  Production-ready with live API verification

d560844704 CLAUDE: Phase 3E-Prep - Refactor GameState to use full LineupPlayerState objects
**Architectural Improvement**: Unified player references in GameState

**Changed**: Make all player references consistent
- BEFORE: current_batter/pitcher/catcher were IDs (int)
- AFTER: current_batter/pitcher/catcher are full LineupPlayerState objects
- Matches pattern of on_first/on_second/on_third (already objects)

**Benefits**:
1. Consistent API - all player references use same type
2. Self-contained GameState - everything needed for resolution
3. No lookups needed - direct access to player data
4. Sets foundation for Phase 3E-Main (adding position ratings)

**Files Modified**:
- app/models/game_models.py: Changed current_batter/pitcher/catcher to objects
- app/core/game_engine.py: Updated _prepare_next_play() to populate full objects
- app/core/state_manager.py: Create placeholder batter on game creation
- tests/unit/models/test_game_models.py: Updated all 27 GameState tests

**Database Operations**:
- No schema changes needed
- Play table still stores IDs (for referential integrity)
- IDs extracted from objects when saving: state.current_batter.lineup_id

**Testing**:
- All 27 GameState tests passing
- No regressions in existing functionality
- Type checking passes

**Next**: Phase 3E-Main - Add PositionRating dataclass and load ratings at game start

fc0e2f100c CLAUDE: Integrate X-Check advancement with full GameState support
Updated X-Check runner advancement functions to properly delegate to
existing result handlers for non-error cases.

Changes:
- Updated x_check_g1/g2/g3 signatures to accept GameState, hit_location,
  and defensive_decision parameters
- 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)

5f42576694 CLAUDE: Remove double-dipping on double play probability
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

fb282a5e54 CLAUDE: Fix critical X-Check bugs and improve dice rolling
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
