Add CardRarityTier enum for pull rate calculations (common through
crown_rare). Add CardSubtype enum for Pokemon classifications (basic,
stage1, stage2, ex, etc.). Update CardDefinition model with new fields
for subtypes and rarity display.
Migrate all usages to the proper mode/value fields:
- Weakness: mode=MULTIPLICATIVE, value=2
- Resistance: mode=ADDITIVE, value=-30
Remove backwards compatibility code and legacy test.

Design Documentation:
- docs/ACTIVE_EFFECTS_DESIGN.md: Comprehensive design for persistent effect system
- Data model (ActiveEffect, EffectTrigger, EffectScope, StackingMode)
- Core operations (register, remove, query effects)
- Integration points (damage calc, energy counting, retreat, lifecycle)
- Effect categories from Pokemon Pocket card research (~372 cards)
- Example implementations (Serperior, Greninja, Mr. Mime, Victreebel)
- Post-launch TODO for generic modifier system
Module README Files:
- backend/app/core/README.md: Core engine overview and key classes
- backend/app/core/effects/README.md: Effects module index and quick reference
- backend/app/core/models/README.md: Models module with relationship diagram
Minor cleanup:
- Revert Bulbasaur weakness to Fire (was test change for Lightning)
- Clean up debug output in game walkthrough
Architectural refactor to eliminate circular imports and establish clean
module boundaries:
- Move enums from app/core/models/enums.py to app/core/enums.py
(foundational module with zero dependencies)
- Update all imports across 30 files to use new enum location
- Set up clean export structure:
- app.core.enums: canonical source for all enums
- app.core: convenience exports for full public API
- app.core.models: exports models only (not enums)
- Add module exports to app/core/__init__.py and app/core/effects/__init__.py
- Remove circular import workarounds from game_state.py
This enables app.core.models to export GameState without circular import
issues, since enums no longer depend on the models package.
All 826 tests passing.
Added stadium_owner_id field to GameState to track who played the stadium:
- stadium_owner_id: str | None tracks the player who played the current stadium
- When a stadium is replaced, old stadium discards to OWNER's pile (not current player)
- Added stadium_owner_id to VisibleGameState for client visibility
- Updated existing test and added 2 new tests for stadium ownership
This fixes the bug where replacing an opponent's stadium would discard
to the current player's pile instead of the opponent's.
797 tests passing.
Changed forced_action from single item to FIFO queue to support
scenarios where multiple forced actions are needed simultaneously:
- forced_actions: list[ForcedAction] replaces forced_action: ForcedAction | None
- Added queue management methods:
- has_forced_action() - check if queue has pending actions
- get_current_forced_action() - get first action without removing
- add_forced_action(action) - add to end of queue
- pop_forced_action() - remove and return first action
- clear_forced_actions() - clear all pending actions
- Updated engine, turn_manager, rules_validator, and visibility filter
- Added 8 new tests for forced action queue including double knockout scenario
This fixes the bug where simultaneous knockouts (e.g., mutual poison damage)
would lose one player's select_active action due to overwriting.
795 tests passing.
Changed ability_uses_this_turn from int to dict[int, int] to track each
ability's usage independently:
- ability_uses_this_turn: dict[int, int] maps ability index to use count
- can_use_ability() now requires ability_index parameter
- Added get_ability_uses() and increment_ability_uses() helper methods
- reset_turn_state() clears the dict instead of setting to 0
This fixes the bug where using one ability could incorrectly block
another ability on the same Pokemon from being used.
789 tests passing.
Major refactor to properly track attached cards and evolution history:
Model Changes (app/core/models/card.py):
- Change attached_energy from list[str] to list[CardInstance]
- Change attached_tools from list[str] to list[CardInstance]
- Add cards_underneath field for evolution stack tracking
- Update attach_energy/detach_energy to work with CardInstance
- Add attach_tool/detach_tool methods
- Add get_all_attached_cards helper
Engine Changes (app/core/engine.py):
- _execute_attach_energy: Pass full CardInstance to attach_energy
- _execute_evolve: Build evolution stack, transfer attachments, clear status
- _execute_retreat: Detached energy goes to discard pile
- Fix: Evolution now clears status conditions (Pokemon TCG standard)
Game State (app/core/models/game_state.py):
- find_card_instance now searches attached_energy, attached_tools, cards_underneath
Turn Manager (app/core/turn_manager.py):
- process_knockout: Discard all attached energy, tools, and evolution stack
Effects (app/core/effects/handlers.py):
- discard_energy: Find owner's discard pile and move detached energy there
- NEW devolve effect: Remove evolution stages with configurable destination
- Fix: Use EffectType.SPECIAL instead of non-existent EffectType.ZONE
Rules Validator (app/core/rules_validator.py):
- Update energy type checking to iterate CardInstance objects
Tests:
- Update existing tests for new CardInstance-based energy attachment
- NEW test_evolution_stack.py with 28 comprehensive tests covering:
- Evolution stack building (Basic -> Stage 1 -> Stage 2)
- Energy/tool transfer and damage carryover on evolution
- Devolve effect (single/multi stage, hand/discard destination, KO check)
- Knockout processing with all attachments going to discard
- find_card_instance for attached cards and evolution stack
All 765 tests pass.
- Implement rules_validator.py with config-driven action validation for all 11 action types
- Implement win_conditions.py with point/prize-based, knockout, deck-out, turn limit, and timeout checks
- Add ForcedAction model to GameState for blocking actions (e.g., select new active after KO)
- Add ActiveConfig with max_active setting for future double-battle support
- Add TrainerConfig.stadium_same_name_replace option
- Add DeckConfig.starting_hand_size option
- Rename from_energy_deck to from_energy_zone for consistency
- Fix unreachable code bug in GameState.get_opponent_id()
- Add 16 coverage gap tests for edge cases (card registry corruption, forced actions, etc.)
- 584 tests passing at 97% coverage
Completes HIGH-005, HIGH-006, TEST-009, TEST-010 from PROJECT_PLAN.json
Core game state models:
- Zone: Card collection with deck operations (draw, shuffle, peek, etc.)
- PlayerState: All player zones, score, and per-turn action flags
- GameState: Complete game state with card registry, turn tracking, win conditions
Test fixtures (conftest.py):
- Sample card definitions: Pokemon (Pikachu, Raichu, Charizard, EX, V, VMAX)
- Trainer cards: Item (Potion), Supporter (Professor Oak), Stadium, Tool
- Energy cards: Basic and special energy
- Pre-configured game states: empty, mid-game, near-win scenarios
- Factory fixtures for CardInstance and SeededRandom
Tests: 55 new tests for game state models (259 total passing)
Note: GameState imported directly from game_state module to avoid
circular imports with config module.
- Add CardDefinition and CardInstance models for card templates and in-game state
- Add Attack, Ability, and WeaknessResistance models for Pokemon card components
- Add 11 action types as discriminated union (PlayPokemon, Evolve, Attack, etc.)
- Split PokemonStage (BASIC, STAGE_1, STAGE_2) from PokemonVariant (NORMAL, EX, GX, V, VMAX, VSTAR)
- Stage determines evolution mechanics, variant determines knockout points
- Update PrizeConfig to use variant for knockout point calculation
- VSTAR and VMAX both worth 3 points; EX, GX, V worth 2 points; NORMAL worth 1 point
Tests: 204 passing, all linting clean
- Create core module structure with models and effects subdirectories
- Add enums module with CardType, EnergyType, TurnPhase, StatusCondition, etc.
- Add RulesConfig with Mantimon TCG defaults (40-card deck, 4 points to win)
- Add RandomProvider protocol with SeededRandom (testing) and SecureRandom (production)
- Include comprehensive tests for all modules (97 tests passing)
Defaults reflect GAME_RULES.md: Pokemon Pocket-style energy deck,
first turn can attack but not attach energy, 30-turn limit enabled.
