- Creates GameHistory record with replay data
- Deletes ActiveGame record
- Clears Redis cache
- All in single transaction

Add pending forced action and game_over fields to GameJoinResult:
- pending_forced_action: Included when player must complete a forced
action (e.g., select new active after KO). Essential for reconnection
so client knows what action is required.
- game_over: Boolean indicating if game has already ended.
- is_your_turn: Now True when player has pending forced action, even if
it's technically opponent's turn.
The join_game method now handles both initial joins and reconnections
(resume). The last_event_id parameter is accepted for future event
replay support.
Tests: 4 new tests for forced action handling and game_over flag.
Total 51 tests for GameService.

Fix audit warnings about empty string defaults hiding data corruption:
1. get_connection_info(): Validate required fields (user_id, connected_at,
last_seen) exist before creating ConnectionInfo. Return None and log
warning for corrupted records instead of returning invalid data.
2. unregister_connection(): Log warning if user_id is missing during
cleanup. Existing code safely handles this (skips cleanup), but now
we have visibility into data corruption.
Test added for corrupted data case.

Three changes to fail fast instead of silently degrading:
1. GameService.create_game: Raise GameCreationError when energy card
definition not found instead of logging warning and continuing.
A deck with missing energy cards is fundamentally broken.
2. CardService.load_all: Collect all card file load failures and raise
CardServiceLoadError at end with comprehensive error report. Prevents
startup with partial card data that causes cryptic runtime errors.
New exceptions: CardLoadError, CardServiceLoadError
3. GameStateManager.recover_active_games: Return RecoveryResult dataclass
with recovered count, failed game IDs with error messages, and total.
Enables proper monitoring and alerting for corrupted game state.
Tests added for energy card error case. Existing tests updated for
new RecoveryResult return type.

Add forced action handling, turn boundary detection, and DB persistence:
- Check for pending forced actions before allowing regular actions
- Only specified player can act during forced action (except resign)
- Only specified action type allowed during forced action
- Detect turn boundaries (turn number OR current player change)
- Persist to Postgres at turn boundaries for durability
- Include pending_forced_action in GameActionResult for client
New exceptions: ForcedActionRequiredError
Tests: 11 new tests covering forced actions, turn boundaries, and
pending action reporting. Total 47 tests for GameService.

- Derive image_path from card ID instead of raw data image_file field
- Use simplified CDN paths: /<set>/<card>.webp (e.g., a1/033-charmander.webp)
- Energy cards use basic/<type>.webp paths
- Fix undefined variable bug in transform_trainer_card
- Update tests to match new path format
- Regenerate all 382 card definitions with correct image_url fields
The converter now falls back to using the source image_url from raw
data when image_file is not available (images not downloaded locally).
- Pokemon cards: use source image_url when image_file is null
- Trainer cards: same fallback behavior
- Regenerated all 382 card definitions with image URLs
Images point to pokemon-zone.com assets for now. When we host our
own images, cards with image_file will use our CDN instead.
- Add lifespan context manager to app/main.py with startup/shutdown hooks
- Wire startup: init_db(), init_redis(), CardService.load_all()
- Wire shutdown: close_db(), close_redis()
- Add /health/ready endpoint for readiness checks
- Add CORS middleware with configurable origins
- Disable docs in production (only available in dev)
- Export get_session_dependency from app/db/__init__.py for FastAPI DI
- Add game_cache_ttl_seconds to Settings (configurable, was hardcoded)
- Fix datetime.utcnow() deprecation (4 occurrences) -> datetime.now(UTC)
- Update test to match S3 image URL (was placeholder CDN)
All 974 tests passing.
The source website uses <span class='energy-text energy-text--type-fire'>
to render inline energy icons. BeautifulSoup's get_text() was stripping
these spans, losing the energy type information and causing merged text
like 'Discard aEnergy' instead of 'Discard a Fire Energy'.
Changes:
- Add ENERGY_TEXT_TYPES mapping for inline energy references
- Add replace_energy_text_spans() to convert spans to text before extraction
- Add extract_effect_text() helper with proper text joining (separator=' ')
- Update parse_attack(), parse_ability(), _parse_trainer_details() to use it
- Fix JSON encoding in convert_cards.py to use UTF-8 (ensure_ascii=False)
Before: 'Discard an Energy from this Pokémon'
After: 'Discard a Fire Energy from this Pokémon'
Re-scraped all 372 cards and regenerated 382 definitions.
Scraper fixes:
- Detect fossil cards (Helix/Dome Fossil, Old Amber) as Trainer/Item cards
- Add text artifact cleaning for stripped energy icons:
- 'aEnergy' -> 'an Energy'
- 'extraEnergy' -> 'extra Energy'
- 'BenchedPokémon' -> 'Benched Pokémon'
- And 20+ other common patterns
Converter improvements:
- Add evolution chain validation to detect broken evolves_from references
- Track conversion errors and validation warnings in _index.json
- Return errors from convert_set() for better debugging
Data fixes:
- Fixed 4 fossil cards (now correctly typed as trainer/item)
- Fixed text artifacts in 46 raw card files
- Regenerated all 382 card definitions
- All evolution chains now valid
Added fix_raw_text.py utility script for batch text cleanup.
- Rename data/cards/ to data/raw/ for scraped data
- Add data/definitions/ as authoritative card data source
- Add convert_cards.py script to transform raw -> definitions
- Generate 378 card definitions (344 Pokemon, 24 Trainers, 10 Energy)
- Add CardService for loading and querying card definitions
- In-memory indexes for fast lookups by type, set, pokemon_type
- search() with multiple filter criteria
- get_all_cards() for GameEngine integration
