+# Backend Test Plan (Updated)
+
+## Overview
+This test plan is designed for iterative execution using sub-agents, with each sub-agent handling a specific phase to avoid exceeding the 300,000 token context limit. Each phase focuses on a distinct subsystem and includes specific test cases and verification steps.
+
+**Last Updated:** 2026-06-08  
+**Status:** Phase 1 Complete - Database & Migration Tests Verified

+- Main agent aggregates results and coordinates fixes
+- Maximum context usage per sub-agent: ~50,000 tokens
+
+### Verification Criteria:
+- All files compile without syntax errors
+- All imports resolve correctly
+- All function signatures match across components
+- All foreign keys reference existing tables
+- All schemas have proper validation
+- All routers have proper dependencies
+- No circular dependencies
+- No orphaned code
+
+### Issue Reporting:
+Each sub-agent should report:
+1. **Critical Issues:** Missing files, broken imports, syntax errors
+2. **Consistency Issues:** Mismatched types, missing fields, incorrect references
+3. **Recommendations:** Improvements, missing features, best practices
+
+---
+
+## Summary
+
+This test plan provides a systematic approach to verifying the entire backend system by breaking it down into 8 manageable phases. Each phase can be executed by a sub-agent independently, ensuring comprehensive coverage while staying within context limits. The plan focuses on consistency, correctness, and completeness of the codebase.
+
+**Current Status:** Phase 1 Complete  
+**Next Phase:** Phase 2 - Model Layer Tests

+
+## 1. Project Overview
+
+**Cockatrice** (v3.1.0 "Graduation Day") is a mature open-source MTG online client/server
+application written in C++20 using Qt 5/6. It has been maintained for many years and
+represents a battle-tested implementation of an online card game.
+
+### Key Architectural Decisions:
+- **Server-Client separation**: The server (`servatrice`) is authoritative; the client
+  (`cockatrice`) is a thin visualizer that sends commands through the server.
+- **Protocol Buffers**: All network communication uses `.proto` files — no custom
+  serialization. This is the canonical contract between components.
+- **Event-driven game loop**: Qt signals/slots drive game state transitions.
+- **Plugin-like library structure**: Core logic lives in `libcockatrice_*` shared libraries.

+
+### 3.2 Game Class Hierarchy
+
+| Class | Role | Key Data |
+|-------|------|----------|
+| `AbstractGame` | Base game abstraction | `gameMetaInfo`, `gameState`, `gameEventHandler`, `playerManager` |
+| `Game` | Concrete online/offline game | Extends AbstractGame with client list |
+| `GameMetaInfo` | Wraps protobuf `ServerInfo_Game` | gameId, maxPlayers, description, started, spectators settings |
+| `GameState` | Board state tracking | currentPhase, activePlayer, hostId, gameTimer, clients |
+| `GameEventHandler` | **Central event dispatch** (~21KB handler) | Processes all game events, prepares commands |
+| `Phase` | Turn phase definitions | 11 phases with sub-phases, colors, sounds |
+
+### 3.3 Phase System (MTG Turn Structure)
+
+```
+Phases::phases[] array contains 11 phases:
+1. Untap
+2. Upkeep
+3. Draw
+4. Main 1
+5. Combat (with sub-phases)
+   - Beginning of Combat
+   - Declare Attackers
+   - Declare Blockers
+   - Combat Damage
+   - End of Combat
+6. Main 2
+7. End of Turn
+8. Cleanup
+(plus unknownPhase as sentinel)
+```
+
+Sub-phases are tracked via `Phases::subPhasesEnd` — the combat phase has 5 sub-phases.
+
+### 3.4 Player System
+
+| Class | Role | File Size |
+|-------|------|-----------|
+| `PlayerManager` | Coordinates all players in a game | ~2.5KB header |
+| `PlayerLogic` | Per-player game logic (actions, rules) | ~10.7KB |
+| `PlayerActions` | Concrete player commands (play, tap, draw, etc.) | **~64KB** — single massive file |
+| `PlayerEventHandler` | Per-player event processing | ~24KB |
+| `EventProcessingOptions` | Flags controlling event processing | ~575B |
+
+### 3.5 Zone System
+
+| Zone | File | Description |
+|------|------|-------------|
+| `CardZone` | `card_zone_logic.cpp/h` | Base class for all zones |
+| `HandZone` | `hand_zone_logic.cpp/h` | Player's hand (secret zone) |
+| `StackZone` | `stack_zone_logic.cpp/h` | The stack ( spells, abilities) |
+| `TableZone` | `table_zone_logic.cpp/h` | Battlefield (permanent zone) |
+| `PileZone` | `pile_zone_logic.cpp/h` | Graveyard, exile, library |
+| `ViewZone` | `view_zone_logic.cpp/h` | Shared view zones (for effects) |
+| `CardZoneAlgorithms` | `card_zone_algorithms.h` | Search, shuffle, sort algorithms |
+
+Each zone type implements its own `CardZoneLogic` subclass.
+
+### 3.6 Command/Event Architecture
+
+```
+User Action (GUI)
+    │
+    ▼
+GameCommand (protobuf message)
+    │
+    ▼
+GameEventHandler.processGameEventContainer()
+    │
+    ▼
+PlayerLogic.handleCommand()
+    │
+    ▼
+CardZoneLogic (state change)
+    │
+    ▼
+GameEvent (sent to all clients)
+    │
+    ▼
+Client receives & displays
+```
+
+### 3.7 Replay System
+
+`replay.cpp/h` — Games are recorded as a stream of protobuf events and can be
+replayed identically. This is a direct serialization of `GameReplay` protobuf messages.
+
+### 3.8 Card State on Board
+
+| Class | Role |
+|-------|------|
+| `CardState` | Card face-up/face-down, tapped, counters |
+| `CardList` | Ordered/unordered collection of cards in a zone |
+| `CounterState` | Life total, poison counters, etc. |
+| `ArrowData` | Targeting arrow visual |
+| `ArrowRegistry` | Manages targeting arrows |
+

+└─────────────────────────────────────────────────────────┘
+```
+
+### 4.2 Key Protocol Messages (from .pb files)
+
+| Category | Example Messages |
+|----------|-----------------|
+| **Game State** | `ServerInfo_Game`, `ServerInfo_Player`, `Event_GameStateChanged` |
+| **Player Actions** | `Command_PlayCard`, `Command_Attack`, `Command_Damage`, `Command_DrawCard` |
+| **Events** | `Event_Join`, `Event_Leave`, `Event_SetActivePlayer`, `Event_SetActivePhase` |
+| **User Management** | `ServerInfo_User`, `Command_Acknowledge`, `Command_SpectateGame` |
+| **Chat** | `Event_GameSay`, `ServerInfo_Chat` |
+| **Decks** | Deck list serialization, sideboard plans |
+
+### 4.3 Authority Model
+
+- **Server is authoritative**: All game state changes go through the server.
+- **Client sends commands, server validates**: The client cannot manipulate the game state directly.
+- **Events are broadcast**: Server sends `GameEvent` containers to all connected clients.
+- **Replays are deterministic**: Same command sequence produces identical game states.
+
+---
+
+## 5. Server Architecture (Servatrice)
+
+### 5.1 Server Class Hierarchy
+
+| Class | Role |
+|-------|------|
+| `Servatrice` | Main server class (~42KB) — manages connections, rooms, games |
+| `ServatriceDatabaseInterface` | Database operations (~58KB) — user accounts, decks, logs |
+| `ServerSocketInterface` | Per-client handler (~106KB) — handles all client messages |
+| `IslInterface` | Inter-server-link for clustering |
+| `ServerLogger` | Centralized logging |
+
+### 5.2 Server Features
+
+- **Room management**: Games are organized in rooms; rooms have game types.
+- **User accounts**: MySQL-backed with authentication, password reset, email.
+- **Deck storage**: Decks saved to database with versioning.
+- **Game logging**: Full game event logs for disputes.
+- **Spectator system**: Spectators can watch (with optional omniscient mode).
+- **Admin commands**: Kicking, banning, game management.
+- **Clustering**: ISL protocol for running multiple servers in a cluster.
+- **Email**: SMTP support for registration/password reset.
+
+### 5.3 Database Schema (MySQL)
+
+The `servatrice.sql` file defines the schema including:
+- User accounts, groups, bans
+- Deck lists with versioning
+- Game logs
+- Room/game state tables
+- Admin logs
+
+---
+
+## 6. Card Database (Oracle)
+
+The `oracle` module downloads and maintains the card database:
+- Sources: MTGJSON data
+- Local storage: SQLite or file-based
+- Features: Card searching, printing history, set filtering
+- Updates: Periodic refresh capability
+
+---
+
+## 7. Deck Management
+
+| Component | Role |
+|-----------|------|
+| `DeckList` | Core deck data structure (cards, sideboard, categories) |
+| `DeckListNodeTree` | Tree structure for organizing decks |
+| `SideboardPlan` | Pre/post-sideboard plan management |
+| `DeckListHistoryManager` | Deck version history |
+| `DeckFilterString` | Card name filtering |
+
+Deck formats supported: Commander, Standard, Modern, Legacy, Vintage, etc.
+
+---
+

+
+## 9. Technology Stack Summary
+
+| Layer | Technology |
+|-------|-----------|
+| Language | C++20 |
+| GUI Framework | Qt 5 or Qt 6 (QtWidgets) |
+| Network Protocol | Protocol Buffers (3.21+) |
+| Build System | CMake 3.10+ |
+| Server Database | MySQL |
+| Card Database | SQLite / file-based (Oracle) |
+| Packaging | CPack (DEB, RPM, NSIS, DMG) |
+| Networking | Qt TCP |
+| Serialization | protobuf |
+| RNG | SFMT (Sobol/Smirnov) |
+| Translations | Qt .ts files |
+| Documentation | Doxygen |
+
+---
+
+## 10. Key Architectural Patterns
+
+| Pattern | Where Used |
+|---------|-----------|
+| **MVC (via Qt)** | `game_state` (model), `game_scene` (view), `GameEventHandler` (controller) |
+| **Event Bus** | Qt signals/slots for all state transitions |
+| **Command Pattern** | `Command_PlayCard`, `Command_Attack`, etc. — all game actions are commands |
+| **Observer** | `GameEventHandler` emits signals to update UI on every state change |
+| **Strategy** | `CardZoneLogic` subclasses (Hand, Stack, Table, Pile, View) |
+| **Facade** | `AbstractGame` wraps all game subsystems behind a single interface |
+| **Adapter** | `GameMetaInfo` wraps protobuf messages with Qt-friendly getters |
+| **Singleton** | Settings cache, database interface |
+| **Memento** | `DeckListMemento` for undo/redo in deck editing |
+| **Repository** | `ServatriceDatabaseInterface` abstracts MySQL access |
+| **Plugin (debatable)** | ISL interface for adding server nodes |
+
+---
+
+## 11. Strengths & Weaknesses (for modern web adaptation)
+
+### Strengths
+- **Clear authority model**: Server is always right — ideal for web multiplayer.
+- **Deterministic replay**: Game events are serialized, enabling perfect replays.
+- **Zone abstraction**: Each zone type is independently implementable.
+- **Phase system**: Well-defined MTG turn structure.
+- **Command/Event separation**: Clean separation between what a player *wants* to do and what *happens*.
+
+### Weaknesses (for web adaptation)
+- **Desktop-first**: Qt Widgets, not designed for browser deployment.
+- **Massive files**: `serversocketinterface.cpp` is 106KB — monolithic.
+- **No web protocol**: Only TCP, no WebSocket, no REST.
+- **No mobile**: No responsive design, no mobile clients.
+- **Complex build**: Qt + CMake + protobuf + MySQL — heavy dev environment.
+- **No real-time scaling**: Single-server architecture (ISL is clustering, not load balancing).
+- **No card images built-in**: External URL loading only.
+- **No API**: No REST/GraphQL for external integrations.
+
+---
+
+## 12. Relevance to Modern Web MTG App
+
+### What to Reuse (Architecture Patterns)
+1. **Event-driven game state**: Server authoritative, client event-driven UI.
+2. **Zone abstraction**: Hand/Stack/Table/Graveyard/Exile/Library as separate zone types.
+3. **Command pattern**: Player actions as discrete commands, validated server-side.
+4. **Phase system**: 11-phase MTG turn structure with sub-phases.
+5. **Replay system**: Serialize game events for replay capability.
+6. **Card database**: Structure for card info, sets, printing history.
+7. **Deck management**: Tree structure, sideboard plans, format support.
+
+### What to Modernize
+1. **Protocol**: Replace protobuf over TCP with **WebSocket** (or gRPC-Web) for browser.
+2. **API**: Add **REST/GraphQL** layer for external integrations.
+3. **Frontend**: Replace Qt Widgets with **React/Next.js** or **Vue 3**.
+4. **State management**: Replace Qt signals/slots with **state machines** (XState) or **Zustand**.
+5. **Backend**: Replace C++/MySQL with **TypeScript/Node.js** or **Python/FastAPI** + **PostgreSQL**.
+6. **Card images**: Bundle card images with the application or use CDN.
+7. **Real-time**: Use **WebSocket** for live game state sync.
+8. **Mobile**: Responsive design from the start.
+9. **Testing**: Unit test the game engine in isolation (no GUI dependency).
+
+### Suggested Tech Stack for Modern Web MTG
+| Component | Recommendation |
+|-----------|---------------|
+| Frontend | Next.js 14+ (React, TypeScript) |
+| Game State | XState (state machines) or Zustand |
+| UI Rendering | React Three Fiber (3D) or PixiJS (2D) |
+| Backend | FastAPI (Python) or Hono (TypeScript) |
+| Database | PostgreSQL (user data) + Redis (game state cache) |
+| Real-time | WebSocket (via FastAPI or Socket.IO) |
+| Card Data | MTGJSON v5 (already available in project) |
+| Auth | JWT + refresh tokens |
+| Deployment | Docker Compose (already used in project) |

+# Backend Endpoint Audit Report
+
+**Date:** 2026-07-24  
+**Scope:** Roadmap Section 2.2 - API Endpoints  
+**Status:** ✅ Review Complete
+
+---
+
+## Executive Summary
+
+The backend has implemented a **simplified card import feature** that differs significantly from the roadmap specification. While the core deck management and user data endpoints are complete, the card import workflow uses a different approach (list-based vs file-based upload).
+
+---
+
+## Section 2.2 - User Deck CRUD ✅ COMPLETE
+
+All deck management endpoints are implemented and match the roadmap:
+
+| Roadmap Endpoint | Status | Implementation |
+|-----------------|--------|----------------|
+| `POST /decks/` | ✅ | Create user deck with DRAFT status |
+| `GET /decks/` | ✅ | List decks with filtering (status, folder, precedent) and pagination |
+| `GET /decks/{deck_id}` | ✅ | Get full deck details with cards |
+| `PATCH /decks/{deck_id}` | ✅ | Update deck (name, status, folder) |
+| `POST /decks/{deck_id}/finalize` | ✅ | Transition DRAFT → FINAL |
+| `DELETE /decks/{deck_id}` | ✅ | Delete deck (admin override for FINAL) |
+| `GET /decks/{deck_id}/cards` | ✅ | List cards with quantities and details |
+
+**Location:** `backend/app/routers/decks.py`  
+**Router Prefix:** `/decks` (included in main.py)
+
+---
+
+## Section 2.2 - Card Search & Suggestions ⚠️ PARTIAL
+
+### Implemented Endpoints
+
+| Endpoint | Status | Notes |
+|----------|--------|-------|
+| `GET /api/mtg/cards/search` | ✅ | Search cards by name (no type/set/color filters) |
+| `GET /api/mtg/cards/{card_name}` | ✅ | Get card by name |
+| `GET /api/mtg/cards/sets` | ✅ | List all sets |
+| `GET /api/mtg/cards/sets/{set_code}` | ✅ | Get specific set |
+| `GET /api/mtg/cards/set/{set_code}` | ✅ | Get cards in set |
+
+**Location:** `backend/app/routers/card_router.py`  
+**Router Prefix:** `/api/mtg/cards` (NOTE: `/mtg/cards` not `/api/cards`)
+
+### Missing Endpoints
+
+| Roadmap Endpoint | Status | Issue |
+|-----------------|--------|-------|
+| `GET /api/cards/search?q={query}&type={type}&set={set}&color={color}` | ❌ | **Filters missing** - search only supports `q` parameter, not type/set/color filters |
+| `GET /api/cards/{card_id}` | ❌ | **ID lookup missing** - only name-based lookup exists |
+| `GET /api/sets/` | ✅ | Implemented as `/api/mtg/cards/sets` |
+| `GET /api/cards/suggest?deck_id={deck_id}&limit={n}` | ❌ | **Suggestion endpoint missing** - no card suggestion functionality |
+
+### Additional Card Endpoints (Not in Roadmap)
+
+| Endpoint | Status | Notes |
+|----------|--------|-------|
+| `GET /api/mtg/cards/types` | ✅ | Get unique card types |
+| `GET /api/mtg/cards/rarities` | ✅ | Get unique card rarities |
+| `GET /api/mtg/cards/statistics` | ✅ | Database statistics |
+
+---
+
+## Section 2.2 - Card Import ❌ SIGNIFICANT DIFFERENCES
+
+### Roadmap Specification
+
+The roadmap specified a **file-based import workflow**:
+- `POST /cards/import` — Upload file (XLSX, CSV, JSON, ODS)
+- `GET /cards/import/{import_id}/status` — Check import progress
+- `GET /cards/import/{import_id}/results` — Get match results with confidence
+- `POST /cards/import/{import_id}/confirm` — Confirm import
+- `GET /user/cards` — List user's imported cards
+- `DELETE /user/cards/{card_import_id}` — Remove from user cards
+
+### Current Implementation
+
+The actual implementation uses a **simplified list-based approach**:
+
+| Current Endpoint | Roadmap Equivalent | Status |
+|-----------------|-------------------|--------|
+| `POST /api/v1/card-import/` | `POST /cards/import` | ✅ **Functionally different** - accepts card name list, not file upload |
+| `GET /api/v1/card-import/status` | `GET /cards/import/{import_id}/status` | ⚠️ **Simplified** - returns current import status, not batch progress |
+| `GET /api/v1/card-import/summary` | `GET /cards/import/{import_id}/results` | ⚠️ **Simplified** - returns match summary, not detailed results |
+| **Missing** | `POST /cards/import/{import_id}/confirm` | ❌ **Not implemented** - no confirmation step |
+| `GET /api/v1/user-data/collection` | `GET /user/cards` | ✅ Implemented under user data |
+| `DELETE /api/v1/user-data/collection/{card_id}` | `DELETE /user/cards/{card_import_id}` | ⚠️ **Different** - deletes by card_id, not import_id |
+
+### Implementation Details
+
+**Current Card Import Flow:**
+1. User sends `POST /api/v1/card-import/` with card name list
+2. System matches names to database cards (exact, case-insensitive, partial matching)
+3. Results stored in `user_card_imports` table as JSON
+4. User can view status and summary via GET endpoints
+
+**Missing File Upload:**
+- No file parsing (XLSX, CSV, JSON, ODS)
+- No batch processing
+- No import ID tracking
+- No confirmation workflow
+
+---
+
+## Section 2.2 - User Data Endpoints ✅ COMPLETE
+
+All user data endpoints are implemented:
+
+### Replays
+| Endpoint | Status |
+|----------|--------|
+| `POST /api/v1/user-data/replays/` | ✅ |
+| `GET /api/v1/user-data/replays/{replay_id}` | ✅ |
+| `PATCH /api/v1/user-data/replays/{replay_id}` | ✅ |
+| `DELETE /api/v1/user-data/replays/{replay_id}` | ✅ |
+
+### Collection (Cards)
+| Endpoint | Status |
+|----------|--------|
+| `POST /api/v1/user-data/collection/` | ✅ |
+| `GET /api/v1/user-data/collection/` | ✅ |
+| `PATCH /api/v1/user-data/collection/{card_id}` | ✅ |
+| `DELETE /api/v1/user-data/collection/{card_id}` | ✅ |
+
+### Groups
+| Endpoint | Status |
+|----------|--------|
+| `POST /api/v1/user-data/groups/` | ✅ |
+| `GET /api/v1/user-data/groups/` | ✅ |
+| `GET /api/v1/user-data/groups/{group_id}` | ✅ |
+| `PATCH /api/v1/user-data/groups/{group_id}` | ✅ |
+| `DELETE /api/v1/user-data/groups/{group_id}` | ✅ |
+
+### Networks
+| Endpoint | Status |
+|----------|--------|
+| `POST /api/v1/user-data/networks/` | ✅ |
+| `GET /api/v1/user-data/networks/` | ✅ |
+| `GET /api/v1/user-data/networks/{network_id}` | ✅ |
+| `PATCH /api/v1/user-data/networks/{network_id}` | ✅ |
+| `DELETE /api/v1/user-data/networks/{network_id}` | ✅ |
+
+### Preferences
+| Endpoint | Status |
+|----------|--------|
+| `GET /api/v1/user-data/preferences/` | ✅ |
+| `PATCH /api/v1/user-data/preferences/` | ✅ |
+
+### Activity
+| Endpoint | Status |
+|----------|--------|
+| `GET /api/v1/user-data/activity/` | ✅ |
+
+**Location:** `backend/app/routers/user_data.py`  
+**Router Prefix:** `/api/v1/user-data`
+
+---
+
+## Section 2.2 - Deck Precedents ✅ COMPLETE
+
+| Endpoint | Status |
+|----------|--------|
+| `GET /decks/precedents` | ✅ |
+| `POST /decks/precedents` | ✅ |
+| `GET /decks/precedents/{precedent_id}` | ✅ |
+| `POST /decks/precedents/{precedent_id}/use` | ✅ |
+
+**Location:** `backend/app/routers/decks.py`
+
+---
+
+## Section 2.2 - Card Suggestions ✅ PARTIAL
+
+| Endpoint | Status |
+|----------|--------|
+| `GET /decks/{deck_id}/suggestions` | ✅ |
+| `POST /decks/{deck_id}/suggestions` | ✅ |
+
+**Note:** These are deck-specific suggestions (add to deck), not the general card suggestion endpoint from the roadmap (`GET /api/cards/suggest`).
+
+---
+
+## Summary of Gaps
+
+### Critical Missing Features
+
+1. **File-based card import workflow**
+   - No file upload (XLSX, CSV, JSON, ODS parsing)
+   - No batch processing with import IDs
+   - No confirmation step
+   - No progress tracking
+
+2. **Card search filters**
+   - Search endpoint missing type, set, and color filters
+   - Only supports name search
+
+3. **Card ID lookup**
+   - No endpoint to get card by ID
+   - Only name-based lookup exists
+
+4. **General card suggestions**
+   - No `GET /api/cards/suggest` endpoint
+   - Only deck-specific suggestions exist
+
+### Implemented but Different from Roadmap
+
+1. **Card import approach** - List-based vs file-based
+2. **Router prefix** - `/api/mtg/cards` vs `/api/cards`
+3. **Deck suggestions** - Deck-specific vs general card suggestions
+
+---
+
+## Recommendations
+
+### Option A: Align with Roadmap (Recommended)
+
+Implement the file-based import workflow:
+1. Add file upload endpoint with XLSX/CSV/JSON/ODS parsing
+2. Create import batch processing with progress tracking
+3. Add confirmation step for matching results
+4. Implement card search filters (type, set, color)
+5. Add card ID lookup endpoint
+6. Implement general card suggestion service
+
+### Option B: Simplify Roadmap
+
+Accept the current simplified implementation:
+1. Document the simplified card import approach
+2. Update ROADMAP.md to reflect actual implementation
+3. Consider adding file upload as future enhancement
+
+---
+
+## File Locations
+
+| Feature | File |
+|---------|------|
+| Deck CRUD | `backend/app/routers/decks.py` |
+| Card Search | `backend/app/routers/card_router.py` |
+| Card Import | `backend/app/routers/card_import.py` |
+| User Data | `backend/app/routers/user_data.py` |
+| Deck Precedents | `backend/app/routers/decks.py` |
+| Deck Suggestions | `backend/app/routers/decks.py` |
+
+---
+
+## Next Steps
+
+1. **Decide on card import approach** (file-based vs list-based)
+2. **If file-based**: Implement file upload and parsing services
+3. **If list-based**: Update ROADMAP.md to reflect actual implementation
+4. **Add missing search filters** to card search endpoint
+5. **Add card ID lookup** endpoint
+6. **Implement general card suggestion service**

+### Data Flow
+1. Backend connects to PostgreSQL (both instances) and Redis on startup
+2. Checks `mtg_refresh_log` in `mtgdata` database for existing data
+3. If no data exists, downloads MTGJSON files from `https://mtgjson.com/api/v5/`
+4. Upserts data into `mtgdata` tables (`mtg_sets`, `mtg_cards`, etc.)
+5. Data available via REST endpoints
+
+### Key Database Connections
+- **Primary DB**: `postgresql+asyncpg://mtgonline_user:mtgonline_password@postgres:5432/mtgonline`
+- **MTG DB**: `postgresql+asyncpg://mtgonline_user:mtgonline_password@mtgdata:5432/mtgdata`
+- **Redis**: `redis://redis:6379`

+```
+
+## Troubleshooting
+
+### Backend can't connect to databases
+- Verify all services are running: `docker compose -f docker-compose.dev.yml ps`
+- Check logs: `docker compose -f docker-compose.dev.yml logs backend`
+- Ensure environment variables match docker-compose.dev.yml
+
+### MTGJSON download fails
+- Check network connectivity to mtgjson.com
+- Verify DATA_DIR has write permissions
+- Check disk space: `df -h`
+- Manual download: `python scripts/download_mtgjson.py`
+
+### Database tables missing
+- Run initialization: `docker exec -i <mtgdata_container_id> psql -U mtgonline_user mtgdata < /path/to/scripts/init-mtgdata.sql`
+- Check tables: `docker exec <mtgdata_container_id> psql -U mtgonline_user mtgdata -c "\dt"`
+
+### CORS errors
+- Check CORS_ORIGINS setting in app/core/settings.py
+- Ensure frontend URL matches allowed origins

+
+## Session Summary: Phase 3 Architecture Planning
+
+### Work Completed
+This session focused on planning Phase 3 (Multiplayer Game Server) architecture and updating documentation to reflect key decisions:
+
+#### 1. Architecture Decisions Documented
+- **Chat System**: Pre-built Docker container (Tinode recommended)
+  - Option A architecture (separate container)
+  - WebSocket-based, frontend connects directly
+  - No custom codebase needed
+  
+- **Audio System**: Pre-built Docker container (Kurento or Janus)
+  - Option A architecture (separate container)
+  - WebRTC-based, frontend connects directly
+  - No custom codebase needed
+  
+- **Game Engine**: Python-based (not C++)
+  - Codebase being developed separately
+  - Will be integrated during Phase 3.1 (Core Game Server)
+  - Python module with volume mount
+
+#### 2. Documentation Created
+- **PHASE_3_PLANNING.md**: Comprehensive planning document with:
+  - Architecture overview with modular design
+  - Chat server solutions (Tinode, SimpleWebSocketChat, Zitadel)
+  - Audio server solutions (Kurento, Janus)
+  - Python game engine integration approach
+  - Development timeline (9 weeks across 4 phases)
+  - Docker configuration examples
+  - Risk assessment
+  - Frontend integration examples
+
+#### 3. HANDOFF.md Updates
+- Removed "Next Phase: V1 Backend" section (work completed)
+- Added "Phase 2 Complete" section summarizing completed work
+- Updated Phase 3 section with new architecture decisions
+- Added architecture diagram showing modular design
+- Documented integration points for chat and audio servers
+- Updated summary table to reflect pre-built solutions
+
+### Key Takeaways
+1. **No custom chat/audio codebase needed** - using pre-built Docker solutions
+2. **Python game engine** will be integrated as a module (not C++)
+3. **Modular architecture** allows independent deployment of chat/audio
+4. **Phase 3.1** will focus on core game server with Python engine integration
+
+### Next Steps
+1. Await Python game engine codebase delivery
+2. Deploy pre-built chat server (Tinode)
+3. Deploy pre-built audio server (Kurento or Janus)
+4. Begin Phase 3.1: Core Game Server implementation
+
+---
+
+## Phase 3: Multiplayer Game Server (In Progress)
+
+### 3.1 Overview
+The multiplayer game server provides a **high-end graphic gameplay option** for players within the same group (groups are set by admins). This is the core real-time gameplay system that replaces the legacy desktop client.
+
+**Architecture Decision**: The multiplayer server uses a **Python-based game engine** (not C++). The game engine codebase is being developed separately and will be integrated during Phase 3.
+
+### 3.2 Architecture
+The multiplayer server follows a **modular architecture** with pre-built Docker containers for chat and audio:
+
+```
+┌─────────────────┐     ┌─────────────────┐     ┌─────────────────┐
+│   Frontend      │────▶│   Game Server   │────▶│   Card Backend  │
+│   (React/TS)    │     │   (Python)      │     │   (FastAPI)     │
+└─────────────────┘     └─────────────────┘     └─────────────────┘
+         │                       │
+         │                       │
+         ▼                       ▼
+┌─────────────────┐     ┌─────────────────┐
+│   Chat Server   │     │   Audio Server  │
+│   (Pre-built    │     │   (Pre-built    │
+│    Docker)      │     │    Docker)      │
+└─────────────────┘     └─────────────────┘
+```
+
+**Key Decisions:**
+- **Chat**: Pre-built Docker container (Tinode recommended) - Option A architecture
+- **Audio**: Pre-built Docker container (Kurento or Janus) - Option A architecture
+- **Game Engine**: Python-based, codebase being developed separately
+
+### 3.3 Game Engine
+A **Python-based game engine** codes all Magic: The Gathering rules directly into the multiplayer system. This means:
+- Cards being played **automatically have the appropriate rules applied** as they are played
+- The engine enforces game mechanics (mana, phases, priority, stack resolution, combat)
+- No manual rule implementation per card — the engine handles it all
+
+**Status**: The game engine codebase is **being developed separately** and will be integrated during Phase 3.1 (Core Game Server).
+
+**Integration Approach:**
+```python
+# game_engine/engine.py
+from game_engine.engine import GameEngine
+
+engine = GameEngine()
+engine.load_card('lightning-bolt')
+result = engine.resolve_effect('lightning-bolt', target='player')
+```
+
+**Docker Volume Mount:**
+```yaml
+volumes:
+  - ./game-engine:/app/game_engine
+```
+
+### 3.4 Graphics
+Graphics are handled in the **front-end development** (React/TypeScript with game board visualization). The multiplayer server provides:
+- Game state synchronization
+- Card data and metadata
+- Real-time updates via WebSocket
+
+The server does not handle rendering — that's the frontend's responsibility.
+
+### 3.5 Chat System
+The multiplayer server uses **pre-built Docker containers** for chat functionality:
+
+#### Text-based Chat
+- **Solution**: Tinode (recommended) or SimpleWebSocketChat
+- **Architecture**: Option A (separate container)
+- **Integration**: WebSocket-based, frontend connects directly
+- **Features**: Room management, message persistence, moderation
+
+**Docker Deployment (Tinode):**
+```bash
+docker run -d \
+  --name tinode \
+  -p 8080:8080 \
+  -v ./tinode-data:/data \
+  --restart unless-stopped \
+  tinode/tinode
+```
+
+**Frontend Integration:**
+```javascript
+import Tinode from 'tinode-sdk';
+
+const tinode = new Tinode({ socket: 'ws://chat-server:8080' });
+await tinode.connect();
+await tinode.subscribe('game-room-123');
+tinode.on('message', (topic, msg) => console.log('Chat:', msg));
+tinode.sendMessage('game-room-123', { text: 'Hello game!' });
+```
+
+#### Audio-based Chat
+- **Solution**: Kurento Media Server (recommended) or Janus Gateway
+- **Architecture**: Option A (separate container)
+- **Integration**: WebRTC-based, frontend connects directly
+- **Features**: Low latency, scalable, open source
+
+**Docker Deployment (Kurento):**
+```bash
+docker run -d \
+  --name kurento \
+  -p 8888:8888 \
+  -p 8443:8443 \
+  --restart unless-stopped \
+  kurento/kurento-media-server:latest
+```
+
+**No custom chat/audio codebase needed** — both are pre-built solutions.
+
+### 3.6 Integration with Card Backend
+The multiplayer server communicates with the card backend (current FastAPI app) via:
+
+- **API Calls**: For authentication, user data, deck retrieval, card lookups
+- **Direct PSQL Queries**: For card data and user deck data
+
+#### Integration Points
+- **Card Backend API** (`http://backend:8000`):
+  - `GET /api/cards/{card_id}` — Get card details for in-game display
+  - `GET /api/cards/search?q=...` — Search cards during gameplay
+  - `GET /api/sets/` — List available sets for game formatting
+
+- **PSQL Direct Access** (via shared connection string):
+  - `mtgdata` database — Read card data (cards, sets, etc.)
+  - `mtgonline` database — Read user decks (for deck validation, game setup)
+
+#### API Endpoints for Play Backend
+- `POST /play/decks/{deck_id}/validate` — Validate deck against card database
+- `GET /play/users/{user_id}/decks` — Get user's FINAL decks for selection
+- `GET /play/cards/{card_id}` — Get card details for game board display
+- `POST /play/chat/text` — Send text message in game/room (via Tinode)
+- `POST /play/chat/audio` — Manage audio chat sessions (via Kurento)
+

+### Data Flow
+
+1. **On startup**, the backend connects to PostgreSQL (both instances) and Redis.
+2. It checks `mtg_refresh_log` in the `mtgdata` database for existing data.
+3. If no data exists, it downloads MTGJSON files from `https://mtgjson.com/api/v5/`, unzips if needed, and upserts them into `mtgdata` tables (`mtg_sets`, `mtg_cards`, etc.).
+4. The data is then available via REST endpoints.
+

+### 2.11 Multiplayer Play Backend — Architecture Blueprint (DERIVED FROM COCKATRICE ANALYSIS)
+
+A detailed architecture analysis of **Cockatrice** (v3.1.0 "Graduation Day") — the mature open-source MTG online client/server — has been completed at `/home/wall-o/projects/mtgonline/C++/ARCHITECTURE_ANALYSIS.md`.
+
+The play backend will follow the same authoritative server model, adapted for a modern web stack:
+
+#### Authority Model

+| `GameMetaInfo` | `GameMetadata` | gameId, maxPlayers, description, started, spectators |
+| `GameState` | `GameBoardState` | currentPhase, activePlayer, hostId, gameTimer |
+| `GameEventHandler` | `GameEventDispatcher` | Central dispatch — processes events, prepares commands (~21KB in Cockatrice) |
+| `PlayerManager` | `PlayerRegistry` | Coordinates all players in a game |
+| `PlayerLogic` | `Player` | Per-player game logic (~10.7KB in Cockatrice) |
+| `PlayerActions` | `PlayerCommands` | Concrete commands: play, attack, tap, draw (~64KB in Cockatrice) |
+| `CardZone` | `Zone` (base class) | Abstract zone — Hand/Stack/Table/Graveyard/Exile/Library |
+| `HandZone` | `Hand` | Player's hand (secret/hidden zone) |
+| `StackZone` | `Stack` | Spells/abilities on the stack |
+| `TableZone` | `Battlefield` | Permanents on the battlefield |
+| `PileZone` | `Pile` (Graveyard, Exile, Library) | Discard/exile/draw piles |
+| `Replay` | `GameReplay` | Serialized event stream for replay |
+| `Phase` | `TurnPhase` | 11-phase MTG turn structure |
+
+#### Turn Phase System (11 Phases with Sub-Phases)

+```
+
+#### Command/Event Flow
+
+```
+User Action (React component)
+    │
+    ▼
+GameCommand (JSON message)
+    │
+    ▼
+GameEventDispatcher.process()
+    │
+    ▼
+Player.handleCommand()
+    │
+    ▼
+ZoneLogic (state mutation)
+    │
+    ▼
+GameEvent (broadcast to all clients via WebSocket)
+    │
+    ▼
+Client receives & updates UI via Zustand/XState
+```
+
+#### Network Protocol Design (Adapted from Cockatrice's protobuf)
+
+Cockatrice uses Protocol Buffers over TCP. The modern web equivalent replaces protobuf with JSON over WebSocket:
+
+| Cockatrice Proto Message | JSON WebSocket Message |
+|---|---|
+| `ServerInfo_Game` | `{ "type": "game_info", "game_id": 1, "max_players": 2, ... }` |
+| `ServerInfo_Player` | `{ "type": "player_info", "player_id": 1, "name": "...", ... }` |
+| `Command_PlayCard` | `{ "type": "cmd_play_card", "card_id": 42, "zone": "hand", ... }` |
+| `Command_Attack` | `{ "type": "cmd_attack", "attacker_id": 7, "targets": [3, 5], ... }` |
+| `Event_Join` | `{ "type": "event_join", "player_id": 2, "properties": {...} }` |
+| `Event_Leave` | `{ "type": "event_leave", "player_id": 1, "reason": "..." }` |
+| `Event_SetActivePlayer` | `{ "type": "event_active_player", "player_id": 1 }` |
+| `Event_SetActivePhase` | `{ "type": "event_active_phase", "phase": 5 }` |
+| `Event_GameSay` | `{ "type": "event_chat", "player_id": 1, "message": "..." }` |
+| `GameReplay` | `{ "type": "replay", "events": [...] }` |
+
+#### Architecture Patterns to Reuse
+
+| Pattern | Cockatrice Usage | Modern Equivalent |
+|---|---|---|
+| **Event Bus** | Qt signals/slots | WebSocket broadcast + Zustand stores |
+| **Command Pattern** | `Command_PlayCard`, `Command_Attack` | JSON command messages, validated server-side |
+| **Observer** | `GameEventHandler` emits signals | WebSocket events trigger UI updates |
+| **Strategy** | `CardZoneLogic` subclasses | Zone classes with strategy pattern (Hand, Stack, Table, Pile, View) |
+| **Facade** | `AbstractGame` | Single `Game` object wrapping all subsystems |
+| **Memento** | `DeckListMemento` for undo | Immutable state snapshots for undo/redo |
+| **Repository** | `ServatriceDatabaseInterface` | SQLAlchemy repositories for game state, decks, logs |
+
+#### Key Decisions (Informed by Cockatrice Analysis)
+
+1. **Server is authoritative** — clients send commands, server validates and broadcasts events. No client-side state manipulation.
+2. **Deterministic replay** — serialize all game events; same command sequence produces identical state.
+3. **Zone abstraction** — each zone type (Hand, Stack, Battlefield, Pile) is independently implementable.
+4. **Phase system** — 11-phase MTG turn with sub-phases, tracked server-side.
+5. **Command/Event separation** — what a player *wants* to do vs. what *happens*.
+
+#### What Modernizes Cockatrice
+
+| Cockatrice Limitation | Modern Web Solution |
+|---|---|
+| TCP only, no web protocol | WebSocket (JSON) |
+| Qt Widgets desktop UI | React/Next.js with PixiJS for game board |
+| C++/MySQL backend | Python/FastAPI + PostgreSQL |
+| Single-server clustering | Stateless game servers + Redis state cache |
+| No mobile support | Responsive design from start |
+| No REST API | FastAPI REST + WebSocket hybrid |
+| Protobuf serialization | JSON over WebSocket |
+| 106KB monolithic server handler | Modular service architecture |
+
+### 2.11 Play Backend Responsibilities (OUT OF SCOPE)
+
+The play backend will implement:
+- [ ] Real-time game state management (server-authoritative)
+- [ ] Multiplayer WebSocket communication
+- [ ] Game rule enforcement (combat, stack resolution, priority)
+- [ ] Deck validation during gameplay
+- [ ] Game history and replay (serialized event log)
+- [ ] Room and game lobbies
+- [ ] Spectator mode
+- [ ] Admin commands (kick, ban, game control)
+
+**Note**: The play backend lives in a separate codebase. Integration points with the card backend:
+- **Card Backend API** (`http://backend:8000`):
+  - Authentication via JWT
+  - Card lookups: `GET /api/cards/{card_id}`
+  - Card search: `GET /api/cards/search?q=...`
+  - Set lists: `GET /api/sets/`
+  - User decks: `GET /api/users/{user_id}/decks`
+- **Direct PSQL Access**:
+  - `mtgdata` database: Read card data, sets, etc.
+  - `mtgonline` database: Read user decks, validate deck legality
+

+## Migration-by-Migration Status
+
+### Migration 000: `000_base_tables.py` — ⚠️ PASS (with warnings)
+
+**Status:** PASS  
+**Issues:** None critical.
+
+| Check | Result |
+|-------|--------|
+| `upgrade()` exists | ✅ |
+| `downgrade()` exists | ✅ |
+| `mtgonline_users` columns correct | ✅ 20 columns, proper PK, indexes, unique constraints |
+| `mtgonline_decklist_files` columns correct | ✅ 11 columns, FK to users, indexes |
+| `mtgonline_rooms` columns correct | ✅ 12 columns, FK to users, indexes |
+| Foreign keys valid | ✅ All reference `mtgonline_users.id` |
+| Indexes created | ✅ `idx_decklist_files_user`, `idx_decklist_files_name`, `idx_rooms_created_by`, `idx_rooms_name` |
+| Unique constraints | ✅ `username`, `email` on users |
+| Downgrade order correct | ✅ Drops dependent tables first |
+
+---
+
+### Migration 001: `001_initial_user_schema.py` — ❌ FAIL (Critical)
+
+**Status:** FAIL  
+**Critical Issue:** Re-creates base tables that migration 000 already created.
+
+#### Critical Issues
+
+| # | Issue | Severity | Details |
+|---|-------|----------|---------|
+| 1 | **Duplicate table creation** | 🔴 CRITICAL | The `upgrade()` function re-creates `mtgonline_users`, `mtgonline_decklist_files`, and `mtgonline_rooms` — tables that migration 000 already created. This will cause `sqlalchemy.exc.ProgrammingError: relation "mtgonline_users" already exists` when running `alembic upgrade head`. |
+| 2 | **Missing `mtgonline_decklist_folders` table** | 🔴 CRITICAL | `user_decks.folder_id` (migration 002) references `mtgonline_decklist_folders.id`, but this table is **never created in any migration**. It only exists in the ORM model (`models.py`). Migration 002 will fail with a FK error. |
+| 3 | **Missing `mtgonline_rooms_gametypes` table** | 🟡 WARNING | `RoomGameType` model references `mtgonline_rooms_gametypes` table, never created in any migration. |
+| 4 | **Missing `mtgonline_bans` table** | 🟡 WARNING | `Ban` model references `mtgonline_bans` table, never created in any migration. |
+| 5 | **Missing `mtgonline_log` table** | 🟡 WARNING | `GameLog` model references `mtgonline_log` table, never created in any migration. |
+| 6 | **Missing `mtgonline_audit` table** | 🟡 WARNING | `AuditLog` model references `mtgonline_audit` table, never created in any migration. |
+
+#### Table Creation Analysis (001 upgrade)
+
+All 15 dependent tables are created correctly with valid foreign keys:
+
+| Table | FK References | Valid? |
+|-------|--------------|--------|
+| `user_sessions` | `mtgonline_users.id` | ✅ |
+| `deck_versions` | `mtgonline_decklist_files.id` | ✅ (if base tables exist) |
+| `game_replays` | `mtgonline_rooms.id` | ✅ (if base tables exist) |
+| `replay_players` | `game_replays.id`, `mtgonline_users.id`, `mtgonline_decklist_files.id` | ✅ |
+| `game_outcomes` | `mtgonline_users.id`, `game_replays.game_uuid` | ✅ |
+| `user_statistics` | `mtgonline_users.id` (PK) | ✅ |
+| `user_card_collection` | `mtgonline_users.id` | ✅ |
+| `card_wishlist` | `mtgonline_users.id` | ✅ |
+| `user_groups` | `mtgonline_users.id` | ✅ |
+| `group_members` | `user_groups.id`, `mtgonline_users.id` | ✅ |
+| `group_chat_messages` | `user_groups.id`, `mtgonline_users.id` | ✅ |
+| `user_networks` | `mtgonline_users.id` | ✅ |
+| `network_members` | `user_networks.id`, `mtgonline_users.id` | ✅ |
+| `user_preferences` | `mtgonline_users.id` (PK) | ✅ |
+| `user_activity_log` | `mtgonline_users.id` | ✅ |
+
+#### Downgrade Analysis
+
+| Check | Result |
+|-------|--------|
+| Drop order correct | ✅ (reverse dependency order) |
+| Indexes dropped | ⚠️ Not explicitly dropped (but `op.drop_table()` handles this) |
+| Base tables dropped | ✅ (at end, after dependents) |
+
+#### Comment Numbering Issue
+
+The `upgrade()` function has inconsistent section numbering:
+- "0. Base Tables" → "0.1. Rooms Table" → "1. User Sessions" → "2. Deck Versions" → **"4. Game Replays"** (skips 3)
+
+---
+
+### Migration 002: `002_user_deck_building_tables.py` — ❌ FAIL (Critical)
+
+**Status:** FAIL  
+**Critical Issue:** References non-existent `mtgonline_decklist_folders` table.
+
+| Check | Result |
+|-------|--------|
+| `upgrade()` exists | ✅ |
+| `downgrade()` exists | ✅ |
+| `user_decks` FK to `mtgonline_decklist_folders.id` | ❌ **Table never created in any migration** |
+| `user_deck_cards` FK to `user_decks.id` | ✅ |
+| `deck_precedent_cards` FK to `deck_precedents.id` | ✅ |
+| `card_suggestions` FK to `user_decks.id` | ✅ |
+| Unique constraints | ✅ `uq_deck_card_unique`, `uq_precedent_card_unique`, `uq_suggestion_unique` |
+| Indexes created | ✅ |
+| Downgrade order correct | ✅ |
+
+#### Additional Issues
+
+| # | Issue | Severity |
+|---|-------|----------|
+| 7 | `user_deck_cards.card_id` has no FK constraint in migration, but model defines `ForeignKey("mtgonline_cards.id")` | 🟡 WARNING |
+| 8 | `card_suggestions.source_card_id` has no FK constraint in migration | 🟡 WARNING |
+| 9 | `deck_precedent_cards.card_id` has no FK constraint in migration | 🟡 WARNING |
+| 10 | `deck_precedents.created_by` has no FK constraint in migration | 🟡 WARNING |
+
+---
+
+### Migration 003: `003_mtgonline_cards_table.py` — ✅ PASS
+
+**Status:** PASS
+
+| Check | Result |
+|-------|--------|
+| `upgrade()` exists | ✅ |
+| `downgrade()` exists | ✅ |
+| `mtgonline_cards` columns correct | ✅ 22 columns |
+| Indexes created | ✅ `idx_mtgonline_cards_name`, `idx_mtgonline_cards_set` |
+| Foreign keys | None (standalone table) |
+| Unique constraints | None |
+
+---
+
+### Migration 004: `004_card_import_table.py` — ⚠️ PASS (with warnings)
+
+**Status:** PASS  
+**Issues:** Minor consistency issues.
+
+| Check | Result |
+|-------|--------|
+| `upgrade()` exists | ✅ |
+| `downgrade()` exists | ✅ |
+| `user_card_imports` columns correct | ✅ 5 columns |
+| FK to `mtgonline_users.id` | ✅ |
+| Unique constraint `uq_user_card_imports_user_id` | ✅ |
+| Index `idx_user_card_imports_user` | ✅ |
+| Primary key definition | ⚠️ `sa.Column('id', sa.Integer(), autoincrement=True, nullable=False)` + `sa.PrimaryKeyConstraint('id')` — redundant but functional |
+
+---
+
+## Cross-Reference: Models vs Migrations
+
+### Tables in Models but NOT in Any Migration (🔴 CRITICAL)
+
+| Model | Table Name | Referenced By |
+|-------|-----------|---------------|
+| `DecklistFolder` | `mtgonline_decklist_folders` | `DecklistFile.folder_id`, `UserDeck.folder_id` |
+| `RoomGameType` | `mtgonline_rooms_gametypes` | `Room.game_types` |
+| `Ban` | `mtgonline_bans` | Admin ban records |
+| `GameLog` | `mtgonline_log` | Game chat logs |
+| `AuditLog` | `mtgonline_audit` | Admin action audit trail |
+| `MtgCardMirror` | `mtg_cards_mirror` | Card mirror for deckbuilding |
+| `DeckCardLink` | `deck_card_links` | Junction: decks ↔ mirrored cards |
+| `CardImportBatch` | `card_import_batches` | Card import batch tracking |
+| `UserCardImportRecord` | `user_card_imports_confirmed` | Confirmed import records |
+
+**These 9 tables must be created in migrations before any migration that references them can succeed.**
+
+### Column Type Mismatches (Model vs Migration)
+
+#### `mtgonline_users`
+
+| Column | Migration | Model | Match? |
+|--------|-----------|-------|--------|
+| `username` | `String(50)` | `String(64)` | ❌ |
+| `password_hash` | `String(255)` | `String(128)` | ❌ |
+| `salt` | `String(32)` | `String(128)` | ❌ |
+| `display_name` | `String(100)` | **Not in model** | ⚠️ |
+| `avatar_url` | `String(500)` | **Not in model** | ⚠️ |
+| `country` | `String(100)` | `String(2)` | ❌ |
+| `real_name` | `String(255)` | `String(128)` | ❌ |
+| `avatar_bmp` | `LargeBinary()` | `Text` | ❌ |
+| `privlevel` | `Integer()` | `String(50)` | ❌ |
+| `is_active` | `Boolean()` | `Boolean()` | ✅ |
+| `is_banned` | `Boolean()` | `Boolean()` | ✅ |

+## Summary of All Issues
+
+### 🔴 Critical (Must Fix Before Deployment)
+
+| # | Issue | Location | Impact |
+|---|-------|----------|--------|
+| 1 | **Migration 001 re-creates base tables** | `001_initial_user_schema.py:upgrade()` | `alembic upgrade head` will FAIL — tables already exist from migration 000 |
+| 2 | **`mtgonline_decklist_folders` never created** | Missing from all migrations | Migration 002 (`user_decks.folder_id`) will FAIL with FK error |
+| 3 | **9 model tables have no migration** | `mtgonline_decklist_folders`, `mtgonline_rooms_gametypes`, `mtgonline_bans`, `mtgonline_log`, `mtgonline_audit`, `mtg_cards_mirror`, `deck_card_links`, `card_import_batches`, `user_card_imports_confirmed` | Any code referencing these tables will fail at runtime |
+
+### 🟡 Warnings (Should Fix)
+
+| # | Issue | Location | Impact |
+|---|-------|----------|--------|
+| 4 | Column type mismatches (15+ columns) | Migration 000/001 vs models | Schema drift — DB won't match ORM definitions |
+| 5 | Column name mismatch (`user_id` vs `owner_id`) | `mtgonline_decklist_files` | ORM won't map correctly |
+| 6 | Missing `unique=True` on `mtgonline_rooms.name` | Migration 000 | Model defines it as unique |
+| 7 | Missing FK constraints on junction table columns | Migration 002 | `card_id`, `source_card_id`, `created_by` lack FK references |
+| 8 | Inconsistent section numbering in migration 001 | `001_initial_user_schema.py` | Code readability |
+| 9 | Redundant PK definition in migration 004 | `004_card_import_table.py` | Works but messy |
+
+### ℹ️ Informational
+
+| # | Issue | Location |
+|---|-------|----------|
+| 10 | Two card table models: `MtgCardMirror` (mtg_cards_mirror) and `MtonlineCard` (mtgonline_cards) | Different tables, different purposes |
+| 11 | Migration 001 creates `user_card_collection` without composite unique constraint that model defines | Model has `UniqueConstraint('user_id', 'card_id', 'is_foil', 'is_alt_art')` |
+| 12 | `user_card_collection` migration missing composite index `idx_collection_user_card` | Model defines it |
+
+---
+
+## Recommendations
+
+### Immediate (Blockers)
+
+1. **Remove duplicate table creation from migration 001** — Delete the `mtgonline_users`, `mtgonline_decklist_files`, and `mtgonline_rooms` `op.create_table()` calls from `001_initial_user_schema.py`. These are already created by migration 000.
+
+2. **Create migration for `mtgonline_decklist_folders`** — This table is referenced by both `mtgonline_decklist_files.folder_id` (model) and `user_decks.folder_id` (migration 002). Add it before migration 002 runs.
+
+3. **Create migrations for all missing tables** — At minimum: `mtgonline_rooms_gametypes`, `mtgonline_bans`, `mtgonline_log`, `mtgonline_audit`, `mtg_cards_mirror`, `deck_card_links`, `card_import_batches`, `user_card_imports_confirmed`.
+
+### Short-term (Consistency)
+
+4. **Align migration schemas with ORM models** — Fix all column type mismatches and missing columns. The migrations should be the source of truth for the database, and models should match.
+
+5. **Add missing FK constraints in migration 002** — Add `ForeignKey` to `card_id`, `source_card_id`, and `created_by` columns.
+
+6. **Add missing unique constraint on `mtgonline_rooms.name`** — Migration 000 should include `unique=True`.
+
+7. **Add missing constraints to `user_card_collection`** — Migration 001 should include the composite unique constraint and index that the model defines.
+
+### Long-term (Architecture)
+
+8. **Decide on migration strategy** — Either:
+   - (a) Remove migration 001's duplicate base tables and keep migration 000 as the single source of base table creation, OR
+   - (b) Remove migration 000 entirely and let migration 001 handle all base tables (but this is risky for a production database).
+
+9. **Add Alembic environment script** — Create `alembic/env.py` with `include_object` filter to auto-detect table creation order and prevent circular dependencies.
+
+10. **Consider using `op.create_foreign_key()` explicitly** — Some FK definitions in the migrations use inline `ForeignKey()` which is fine, but explicit `op.create_foreign_key()` calls are more readable and Alembic can better track them for downgrade.

+- [ ] Verify UNIQUE constraints prevent duplicates
+- [ ] Verify JSONB columns store data correctly
+
+### 5. Test Rollback
+- [ ] Execute downgrade migration
+- [ ] Verify all tables are dropped
+- [ ] Verify columns are removed from existing tables
+

+# Phase 2 - Model Layer Test Report
+
+**Date:** 2026-07-23  
+**Scope:** SQLAlchemy model definitions vs. Alembic migration schema  
+**Status:** ❌ FAIL (2 Critical, 3 Major, 4 Minor issues)
+
+---
+
+## Summary
+
+| Category | Count |
+|----------|-------|
+| Critical | 2 |
+| Major | 3 |
+| Minor | 4 |
+| **Total Issues** | **9** |
+| Models Verified | 28 classes across 7 files |
+| Migrations Verified | 6 files (000–005) |
+| Tables Verified | 27 tables |
+
+**Overall: FAIL** — Two critical issues will prevent the application from starting:
+1. A circular import between `models.py` and `mirror_models.py` will cause `ImportError` at runtime
+2. Migration `005` imports models to extract column definitions, triggering the same circular import
+
+---
+
+## Issues Found
+
+### CRITICAL
+
+#### Issue #1: Circular Import — `models.py` ↔ `mirror_models.py`
+
+- **File:** `app/models/models.py` (line 209) and `app/models/mirror_models.py` (line 100)
+- **Severity:** Critical
+- **Description:** `models.py` imports `MtgCardMirror` and `DeckCardLink` from `mirror_models.py` at the top of the file. `mirror_models.py` imports `DecklistFile` from `models.py` at the top, and then at the bottom (line 100) imports `DecklistFile` again and dynamically adds a `card_links` relationship to it. This creates a circular import chain:
+  ```
+  models.py → mirror_models.py → models.py (circular!)
+  ```
+- **Impact:** Any code that imports from either `models.py` or `mirror_models.py` (including Alembic migrations, Flask app startup, and tests) will fail with `ImportError` or `AttributeError`.
+- **Recommendation:** Restructure the import. Move the dynamic `DecklistFile.card_links` relationship addition to a separate initialization file (e.g., `app/models/relationships.py`) that is imported after all models are defined, or use lazy string references in `back_populates`.
+
+#### Issue #2: Migration `005_missing_tables.py` Imports Models with Circular Dependency
+
+- **File:** `alembic/versions/005_missing_tables.py` (lines 28–31)
+- **Severity:** Critical
+- **Description:** This migration imports ORM models (`MtgSet`, `MtgCard`, `MtgCardMirror`, `DeckCardLink`, `CardImportBatch`, `UserCardImportRecord`) to extract their column definitions for `op.create_table()`. However, importing `MtgCardMirror` triggers the circular import described in Issue #1.
+  ```python
+  from app.models.mtg_models import MtgSet, MtgCard
+  from app.models.mirror_models import MtgCardMirror, DeckCardLink
+  from app.models.card_import_batch import CardImportBatch
+  from app.models.user_card_import_record import UserCardImportRecord
+  ```
+- **Impact:** Running `alembic upgrade head` will fail at migration `005` with an `ImportError`. The database cannot be brought online.
+- **Recommendation:** Replace model imports with raw SQLAlchemy column definitions in the migration. Do not import ORM models in Alembic migrations — they are not guaranteed to be importable during migration execution.
+
+---
+
+### MAJOR
+
+#### Issue #3: Orphaned Migration `004_card_import_table.py` — No Corresponding Model
+
+- **File:** `alembic/versions/004_card_import_table.py`
+- **Severity:** Major
+- **Description:** This migration creates a `user_card_imports` table with columns `id`, `user_id`, `card_names_json`, `created_at`, `updated_at`. However, no SQLAlchemy model class exists for this table anywhere in the codebase. The newer models `CardImportBatch` (`card_import_batches`) and `UserCardImportRecord` (`user_card_imports_confirmed`) appear to supersede this table, but the old migration was never cleaned up.
+- **Impact:** Database schema drift — an unused table exists in the database with no application code to interact with it.
+- **Recommendation:** Either (a) create a model for `user_card_imports` if it's still needed, or (b) add a downgrade migration to drop the table and remove `004_card_import_table.py`.
+
+#### Issue #4: `MtgCardMirror.source_id` FK References Cross-Database Table
+
+- **File:** `app/models/mirror_models.py` (line 33)
+- **Severity:** Major
+- **Description:** `MtgCardMirror.source_id` is defined as `Column(Integer, nullable=True, index=True)` with a comment stating it "References mtg_cards.id". However, `mtg_cards` lives in the separate `mtgdata` PostgreSQL database, not in the `mtgonline` database where `mtg_cards_mirror` resides. The migration `005` does **not** create a `ForeignKey` constraint on this column — only an index. The model also lacks a `ForeignKey` definition.
+- **Impact:** No referential integrity enforcement. If `mtg_cards` records are deleted/updated in the source database, the mirror table will have orphaned `source_id` values with no way to detect or clean them up.
+- **Recommendation:** This is likely intentional (cross-DB references can't be enforced with FK constraints in PostgreSQL). Add a comment in the model clarifying this is a logical reference, not a physical FK. Consider adding a periodic sync validation job.
+
+#### Issue #5: Migration `002` Name Misleading — Deck Building Tables Split Across 002 and 003
+
+- **File:** `alembic/versions/002_user_deck_building_tables.py` and `003_mtgonline_cards_table.py`
+- **Severity:** Major
+- **Description:** Migration `002` is named "Add user deck building tables" but only creates the `user_decks` table. Migration `003` ("Add mtgonline_cards table") actually creates the remaining deck building tables: `user_deck_cards`, `deck_precedents`, `deck_precedent_cards`, and `card_suggestions`. The naming is misleading and makes it difficult to understand the schema evolution.
+- **Impact:** Developers reading migration history will be confused about which tables belong to which feature.
+- **Recommendation:** Rename `003` to something like "Add mtgonline_cards and deck building junction tables" or split `003` into separate migrations for clarity.
+
+---
+
+### MINOR
+
+#### Issue #6: `MtonlineCard` Typo in Class Name
+
+- **File:** `app/models/models.py` (line 51)
+- **Severity:** Minor
+- **Description:** The class is named `MtonlineCard` (missing the 'g'), but the table is `mtgonline_cards` and the model file is `models.py`. The correct name should be `MtgonlineCard`. This typo is used consistently throughout the codebase (e.g., in `user_deck.py` line 18), so changing it would require updating all references.
+- **Impact:** Code readability and consistency. No functional impact since the `__tablename__` is correct.
+- **Recommendation:** Rename to `MtgonlineCard` across all files (`models.py`, `user_deck.py`, `__init__.py`).
+
+#### Issue #7: Migration `003` Creates Indexes Not Defined in Model
+
+- **File:** `alembic/versions/003_mtgonline_cards_table.py` (lines 44–45)
+- **Severity:** Minor
+- **Description:** The migration creates two individual indexes on `mtgonline_cards`:
+  - `idx_mtgonline_cards_name` on `name`
+  - `idx_mtgonline_cards_set` on `set_code`
+  
+  But the model (`MtonlineCard` in `models.py`) does not define these as SQLAlchemy `Index` objects. The model only defines a composite index `idx_mtgonline_cards_name_set` on `(name, set_id)` — note this references `set_id` which doesn't exist in `mtgonline_cards` (the column is `set_code`).
+- **Impact:** The migration indexes will exist in the database but won't be managed by SQLAlchemy. If the model is ever used to recreate the schema, these indexes will be lost.
+- **Recommendation:** Add matching `Index` definitions to the `MtonlineCard` model class.
+
+#### Issue #8: `UserDeck.folder` Relationship Backref Not Defined on `DecklistFolder`
+
+- **File:** `app/models/user_deck.py` (line 54)
+- **Severity:** Minor
+- **Description:** `UserDeck` defines `folder = relationship("DecklistFolder", backref="user_decks")`. However, `DecklistFolder` in `models.py` does not define a corresponding `user_decks` relationship or backref. The `backref` will create it dynamically, but this is fragile and not explicit.
+- **Impact:** The relationship will work, but it's not visible in `DecklistFolder`'s definition, making the schema harder to understand.
+- **Recommendation:** Add an explicit `user_decks = relationship("UserDeck", back_populates="folder")` to `DecklistFolder`.
+
+#### Issue #9: `UserCardCollection` Migration Uses Separate Indexes Instead of Composite
+
+- **File:** `alembic/versions/001_initial_user_schema.py` (lines 147–148)
+- **Severity:** Minor
+- **Description:** The migration creates two separate indexes (`idx_collection_user` on `user_id`, `idx_collection_card` on `card_id`) but the model defines a composite index `idx_collection_user_card` on `('user_id', 'card_id')`. The composite index is more efficient for queries filtering on both columns, but the migration only creates individual indexes.
+- **Impact:** Slightly suboptimal query performance. The unique constraint `uq_collection_unique` provides some coverage, but a separate composite index would be more efficient.
+- **Recommendation:** Update the migration to create the composite index `idx_collection_user_card` on `['user_id', 'card_id']` instead of (or in addition to) the two separate indexes.

+
+## Recommendations
+
+### Immediate (Blockers)
+
+1. **Fix circular import** between `models.py` and `mirror_models.py` — This prevents the application from starting and migrations from running.
+2. **Fix migration `005`** — Replace model imports with raw column definitions to avoid triggering the circular import.
+
+### Short-Term
+
+3. **Clean up orphaned migration `004`** — Either create a model for `user_card_imports` or drop the table.
+4. **Rename `MtonlineCard` → `MtgonlineCard`** — Fix the typo for code consistency.
+5. **Add missing indexes to `MtonlineCard` model** — Match the indexes created in migration `003`.
+
+### Long-Term
+
+6. **Add explicit backref on `DecklistFolder`** for `UserDeck.folder` relationship.
+7. **Update migration `001`** to use composite index for `user_card_collection` instead of separate indexes.
+8. **Rename migration `003`** to clarify it includes deck building junction tables.
+9. **Document cross-DB reference** for `MtgCardMirror.source_id` — Add a comment clarifying it's a logical (not physical) FK.

+## Appendix: Column-by-Column Comparison
+
+### `mtgonline_users` (User) — Migration 000 vs Model
+| Column | Migration | Model | Match |
+|--------|-----------|-------|-------|
+| id | Integer PK | Integer PK ✅ |
+| username | String(64) unique nullable=False index | String(64) unique nullable=False index ✅ |
+| password_hash | String(128) nullable=False | String(128) nullable=False ✅ |
+| salt | String(128) nullable=False | String(128) nullable=False ✅ |
+| email | String(255) nullable=True index | String(255) nullable=True index ✅ |
+| country | String(2) nullable=True | String(2) nullable=True ✅ |
+| real_name | String(128) nullable=True | String(128) nullable=True ✅ |
+| avatar_bmp | Text nullable=True | Text nullable=True ✅ |
+| privlevel | String(50) server_default='User' | String(50) default="User" ⚠️ |
+| is_active | Boolean default=True | Boolean default=True ✅ |
+| is_banned | Boolean default=False | Boolean default=False ✅ |
+| ban_reason | Text nullable=True | Text nullable=True ✅ |
+| ban_ends | DateTime nullable=True | DateTime nullable=True ✅ |
+| vip_status | Integer default=0 | Integer default=0 ✅ |
+| vip_expiry | DateTime nullable=True | DateTime nullable=True ✅ |
+| creation_date | DateTime server_default=now() | DateTime server_default=now() ✅ |
+| last_login | DateTime nullable=True | DateTime nullable=True ✅ |
+
+> ⚠️ `privlevel`: Migration uses `server_default='User'` (DB-level default), model uses `default="User"` (Python-level default). Both work but `server_default` is preferred for PostgreSQL.
+
+### `mtgonline_cards` (MtonlineCard) — Migration 003 vs Model
+All 23 columns match exactly. Migration creates additional indexes (`idx_mtgonline_cards_name`, `idx_mtgonline_cards_set`) not present in the model.
+
+### `user_card_collection` (UserCardCollection) — Migration 001 vs Model
+All 13 columns match. Migration creates separate indexes on `user_id` and `card_id`; model defines composite index `idx_collection_user_card` on both columns.
+
+### `card_wishlist` (CardWishlist) — Migration 001 vs Model
+All 5 columns match. Unique constraint `uq_wishlist_user_card` on `(user_id, card_id)` matches.
+
+### `user_decks` (UserDeck) — Migration 002 vs Model
+All 11 columns match exactly.
+
+### `user_deck_cards` (UserDeckCard) — Migration 003 vs Model
+All 5 columns match. Unique constraint `uq_deck_card_unique` on `(deck_id, card_id, zone)` matches.
+
+### `deck_precedents` (DeckPrecedent) — Migration 003 vs Model
+All 7 columns match exactly.
+
+### `deck_precedent_cards` (DeckPrecedentCard) — Migration 003 vs Model
+All 4 columns match. Unique constraint `uq_precedent_card_unique` on `(precedent_id, card_id, zone)` matches.
+
+### `card_suggestions` (CardSuggestion) — Migration 003 vs Model
+All 7 columns match. Unique constraint `uq_suggestion_unique` on `(deck_id, card_id, source_card_id)` matches.
+
+### `mtg_sets` (MtgSet) — Migration 005 vs Model
+All 15 columns match exactly.
+
+### `mtg_cards` (MtgCard) — Migration 005 vs Model
+All 17 columns match. Migration creates composite indexes `idx_mtg_cards_name_set`, `idx_mtg_cards_type`, `idx_mtg_cards_rarity` that match model definitions.
+
+### `mtg_cards_mirror` (MtgCardMirror) — Migration 005 vs Model
+All 24 columns match exactly.
+
+### `deck_card_links` (DeckCardLink) — Migration 005 vs Model
+All 4 columns match. Unique constraint `uq_deck_card_link` and indexes `idx_deck_card_deck`, `idx_deck_card_card` match.
+
+### `card_import_batches` (CardImportBatch) — Migration 005 vs Model
+All 13 columns match exactly.
+
+### `user_card_imports_confirmed` (UserCardImportRecord) — Migration 005 vs Model
+All 5 columns match exactly.

+# Magic: The Gathering Rules Engine
+
+A Python-based rules engine designed to validate card text, game actions, and game states against the comprehensive rules of Magic: The Gathering (MTG).
+
+## Overview
+
+This engine provides a programmatic way to handle the complexities of MTG keywords and rules. It allows developers to verify if card text is consistent with established keywords and to validate whether specific game actions are legal according to the rules database.
+
+## Key Features
+
+- **Comprehensive Keyword Database**: Manages hundreds of keyword abilities, keyword actions, and ability words, complete with their corresponding rule numbers and definitions.
+- **Card Text Validation**: Analyzes card text to identify keywords and flag potential errors or misspellings.
+- **Action & State Validation**: Provides logic to verify if a specific game action (e.g., an attack or a cast) is valid given the current game state.
+- **Rule Reference Lookup**: Quick retrieval of rule text and summaries for any supported keyword.
+- **Automatic Update System**: Includes an updater to keep the rules database current.
+
+## Project Structure
+
+| File | Description |
+| :--- | :--- |
+| `engine.py` | High-level interface for the rules engine. |
+| `rules_engine.py` | Core logic for rule application and game state validation. |
+| `keywords.py` | The primary definitions and data for MTG keywords. |
+| `keywords_db.py` | Handles the loading and management of the keyword database. |
+| `keyword_validator.py` | Logic for parsing text and validating keywords. |
+| `validator.py` | General purpose validation utilities. |
+| `updater.py` & `update_check.py` | Tools for checking and applying engine updates. |
+| `test_engine.py` | Comprehensive test suite for verifying engine stability. |
+
+## Getting Started
+
+### Prerequisites
+- Python 3.10+
+
+### Running Tests
+To verify the installation and ensure the engine is functioning correctly, run the test suite:
+
+```bash
+python3 test_engine.py
+```
+
+## Usage Example
+
+```python
+from mtg_rules_engine.engine import RulesEngine
+
+engine = RulesEngine()
+
+# Validate card text
+errors = engine.validate_card("Flying, Trample")
+if not errors:
+    print("Card text is valid.")
+
+# Get rule information
+info = engine.get_keyword_info('flying')
+print(f"Rule {info['rule']}: {info['definition']}")
+```
+
+## Maintenance

+  - Card casting (type, mana cost, timing)
+  - Creature combat (attackers, blockers, damage assignment)
+  - Spell resolution (targets, costs, effects)
+  - Zone transitions (enters/leaves battlefield, stack)
+  - Keyword ability interactions
+  - State-based actions (lethal damage, legend rules)
+
+Built on the hardcoded keyword database from keywords_db.py
+and the validator from keyword_validator.py.

+
+---
+
+## 1. `main.py` — Router Registration
+
+### Status: ⚠️ FAIL
+
+### Critical Issues
+
+**C-01: `card_router.router` double-prefix path conflict**
+- `card_router.py` defines `router = APIRouter(prefix="/api/cards", ...)`
+- `main.py` mounts it with `app.include_router(card_router.router, prefix="/api", ...)`
+- **Result:** All card search endpoints resolve to `/api/api/cards/...` instead of `/api/cards/...`
+- **Impact:** All card search, card-by-id, sets, types, rarities, and suggest endpoints are broken.
+
+### Warnings
+
+**W-01: `interactions.router` has internal prefix `/interactions` but mounted without prefix**
+- `interactions.py`: `router = APIRouter(prefix="/interactions", ...)`
+- `main.py`: `app.include_router(interactions.router, ...)` (no prefix)
+- **Result:** Paths resolve correctly to `/interactions/...` — this is intentional and works, but is inconsistent with `card_router` pattern.
+
+**W-02: `refresh.router` has internal prefix `/mtgjson` but mounted without prefix**
+- `refresh.py`: `router = APIRouter(prefix="/mtgjson", ...)`
+- `main.py`: `app.include_router(refresh.router)` (no prefix)
+- **Result:** Paths resolve correctly to `/mtgjson/...` — same pattern as W-01.
+
+### Info
+
+**I-01:** `games.router` is imported as `games` (the package) and mounted with `prefix="/games"`. The actual router is at `app.routers.games.router.router`. This works because FastAPI resolves `games.router` to the `router` attribute of the `games` module.
+
+**I-02:** All routers use consistent `Depends(get_db)` or `Depends(mtg_get_db)` for database sessions.
+
+---
+
+## 2. `auth.py` — Authentication Router
+
+### Status: ✅ PASS
+
+### Endpoints
+| Method | Path | Response Model | Auth Required |
+|---|---|---|---|
+| POST | `/auth/login` | `LoginResponse` | ❌ (public) |
+| POST | `/auth/refresh` | `TokenResponse` | ❌ (token-based) |
+| POST | `/auth/register` | `UserResponse` | ❌ (public) |
+| GET | `/auth/me` | `UserResponse` | ✅ (token query param) |
+
+### Warnings
+
+**W-01: `get_current_user` endpoint uses query parameter for token**
+- The `/auth/me` endpoint expects `token: str` as a query parameter rather than a Bearer token in the Authorization header.
+- This is non-standard for JWT authentication and inconsistent with how `get_current_user` dependency works in other routers (which reads from the Authorization header).
+- **Recommendation:** Consider using `Authorization: Bearer <token>` header for consistency, or document this as a deliberate design choice.
+
+### Info
+
+- Login endpoint correctly omits `get_current_user` dependency (public endpoint).
+- All response models match their schema definitions in `schemas.py`.
+- Proper HTTP status codes: 401 for invalid credentials, 403 for disabled/banned accounts, 409 for duplicate username/email.
+
+---
+
+## 3. `users.py` — User Management Router
+
+### Status: ✅ PASS
+
+### Endpoints
+| Method | Path | Response Model | Auth Required |
+|---|---|---|---|
+| GET | `/users/{user_id}` | `UserResponse` | ✅ |
+| PATCH | `/users/{user_id}` | `UserResponse` | ✅ (self-only) |
+| POST | `/users/{user_id}/ban` | dict | ✅ (admin/judge) |
+| POST | `/users/{user_id}/unban` | dict | ✅ (admin/judge) |
+
+### Info
+
+- Self-update protection is correctly implemented (users can only update their own profile).
+- Ban/unban endpoints properly check for admin/judge privileges.
+- `UserUpdate` schema fields are correctly mapped to model fields.
+- Password hashing is applied only when `new_password` is provided.
+
+---
+
+## 4. `decks.py` — Deck Management Router
+
+### Status: ✅ PASS
+
+### Endpoints
+| Method | Path | Response Model | Auth Required |
+|---|---|---|---|
+| GET | `/decks/` | `UserDeckListResponse` | ✅ |
+| POST | `/decks/` | `UserDeckResponse` | ✅ |
+| GET | `/decks/{deck_id}` | `UserDeckResponse` | ✅ |
+| PATCH | `/decks/{deck_id}` | `UserDeckResponse` | ✅ |
+| DELETE | `/decks/{deck_id}` | `MessageResponse` | ✅ |
+| POST | `/decks/{deck_id}/finalize` | `DeckFinalizeResponse` | ✅ |
+| POST | `/decks/{deck_id}/cards` | `DeckCardResponse` | ✅ |
+| GET | `/decks/{deck_id}/cards` | `DeckCardListResponse` | ✅ |
+| PATCH | `/decks/{deck_id}/cards/{card_id}` | `DeckCardResponse` | ✅ |
+| DELETE | `/decks/{deck_id}/cards/{card_id}` | `MessageResponse` | ✅ |
+| GET | `/decks/precedents` | `PrecedentListResponse` | ✅ |
+| POST | `/decks/precedents` | `PrecedentResponse` | ✅ |
+| GET | `/decks/precedents/{precedent_id}` | `PrecedentResponse` | ✅ |
+| POST | `/decks/precedents/{precedent_id}/use` | dict | ✅ |
+| POST | `/decks/search/cards` | `CardSearchResponse` | ✅ |
+| GET | `/decks/{deck_id}/suggestions` | `SuggestionListResponse` | ✅ |
+| POST | `/decks/{deck_id}/suggestions` | `SuggestionResponse` | ✅ |
+
+### Warnings
+
+**W-01: `DeckPrecedent` imported from `app.models.user_deck`**
+- `DeckPrecedent` and `DeckPrecedentCard` are imported from `app.models.user_deck` but may belong in a different model file. Verify model placement is correct.
+
+### Info
+
+- FINAL deck protection is consistently enforced across all mutating endpoints.
+- Owner verification is applied on all deck-access endpoints.
+- Pagination is consistently implemented with `page`/`page_size` query parameters.
+- Card search uses `ilike` for case-insensitive matching across name, type_line, and mana_cost.
+- Precedent cloning correctly copies cards from precedent to new deck.
+
+---
+
+## 5. `card_import.py` — Card Import Router
+
+### Status: ⚠️ FAIL
+
+### Endpoints
+| Method | Path | Response Model | Auth Required |
+|---|---|---|---|
+| POST | `/api/v1/card-import/import` | `CardImportResponse` | ✅ |
+| GET | `/api/v1/card-import/import/{import_id}/status` | `CardImportStatusResponse` | ✅ |
+| GET | `/api/v1/card-import/import/{import_id}/results` | `CardImportSummary` | ✅ |
+| POST | `/api/v1/card-import/import/{import_id}/confirm` | `MessageResponse` | ✅ |
+| GET | `/api/v1/card-import/user/cards` | `List[Dict]` | ✅ |
+| DELETE | `/api/v1/card-import/user/cards/{card_import_id}` | `MessageResponse` | ✅ |
+| GET | `/api/v1/card-import/user/decks` | `List[Dict]` | ✅ |
+
+### Critical Issues
+
+**C-01: `get_user_cards` endpoint has no response model**
+- Returns `List[Dict[str, Any]]` instead of a proper Pydantic response model.
+- Inconsistent with all other endpoints in the project which use typed response models.
+- **Impact:** OpenAPI documentation will show untyped response, and clients cannot rely on response structure.
+- **Recommendation:** Create a `UserCardResponse` schema and use it as `response_model`.
+
+### Warnings
+
+**W-01: Temp file cleanup not guaranteed**
+- `upload_card_import` creates a temp file with `tempfile.NamedTemporaryFile` but only wraps parsing in a try/except. If the file is read successfully but processing fails afterward, the temp file is never cleaned up.
+- **Recommendation:** Use `with tempfile.NamedTemporaryFile(...)` as a context manager, or add a `finally` block to delete the temp file.
+
+### Info
+
+- File type validation correctly restricts to xlsx, csv, json, ods.
+- Owner verification is applied on all import-related endpoints.
+- Import confirmation correctly checks for duplicates before adding to collection.
+
+---
+
+## 6. `card_router.py` — Card Search Router
+
+### Status: ⚠️ FAIL
+
+### Endpoints
+| Method | Path | Response Model | Auth Required |
+|---|---|---|---|
+| GET | `/api/cards/search` | `CardSearchResponse` | ❌ |
+| GET | `/api/cards/{card_id}` | `CardResponse` | ❌ |
+| GET | `/api/cards/sets` | `List[SetResponse]` | ❌ |
+| GET | `/api/cards/types` | `List[CardTypeResponse]` | ❌ |
+| GET | `/api/cards/rarities` | `List[str]` | ❌ |
+| GET | `/api/cards/suggest` | `List[Dict]` | ❌ |
+
+### Critical Issues
+
+**C-01: Double-prefix path conflict (see main.py C-01)**
+- Router has `prefix="/api/cards"` and is mounted at `prefix="/api"`.
+- All endpoints resolve to `/api/api/cards/...` — **all 6 endpoints are broken.**
+
+**C-02: `suggest_cards_endpoint` queries wrong database**
+- Uses `mtg_get_db` dependency (MTG card database) but checks `UserDeck` model which lives in the main application database.
+- The `UserDeck` query will fail because it's running against the MTG database which doesn't have the `user_decks` table.
+- **Impact:** Card suggestion endpoint will always return 404 or crash.
+- **Recommendation:** Use `get_db` (main database) for the `UserDeck` check, or query the MTG database for deck-related data if that's the intended design.
+
+### Warnings
+
+**W-01: No authentication on card search endpoints**
+- All 6 endpoints are publicly accessible without authentication.
+- This may be intentional for a card search feature, but should be documented.
+- No rate limiting is applied.
+
+### Info
+
+- Redis caching is consistently applied across all endpoints with appropriate TTLs.
+- Response format uses `{"cached": bool, "results": ...}` pattern — non-standard but consistent within this router.
+
+---
+
+## 7. `interactions.py` — Card Interactions Router
+
+### Status: ⚠️ FAIL
+
+### Endpoints
+| Method | Path | Response Model | Auth Required |
+|---|---|---|---|
+| GET | `/interactions/synergies/{card_id}` | dict | ❌ |
+| GET | `/interactions/counters/{card_id}` | dict | ❌ |
+| GET | `/interactions/evolutions/{card_id}` | dict | ❌ |
+| GET | `/interactions/recommend/{card_id}` | dict | ❌ |
+| GET | `/interactions/search/synergies` | dict | ❌ |
+| GET | `/interactions/search/counters` | dict | ❌ |
+| GET | `/interactions/search/evolutions` | dict | ❌ |
+| GET | `/interactions/stats/{card_id}` | dict | ❌ |
+
+### Critical Issues
+
+**C-01: All endpoints return untyped `dict` responses**
+- None of the 8 endpoints use `response_model` — they all return raw dictionaries.
+- This means OpenAPI/Swagger docs will show no response schema, and clients have no type safety.
+- **Recommendation:** Create response schemas (e.g., `SynergyResponse`, `CounterResponse`, etc.) and apply them.
+
+### Warnings
+
+**W-01: SQL injection risk with f-string query construction**
+- Multiple endpoints build SQL WHERE clauses using f-strings: `f"WHERE {where_clause}"`.
+- While parameter binding is used for values, the column/condition construction is not sanitized.
+- If any user-controlled input reaches the `synergy_type`, `counter_type`, or `evolution_type` query parameters, it could be injected into the WHERE clause.
+- **Current mitigation:** Query parameters are validated by FastAPI type checking, but column names in `ORDER BY` and table references are not parameterized.
+- **Recommendation:** Use a whitelist for filter values or use SQLAlchemy core expressions instead of raw SQL.
+
+**W-02: No authentication on any endpoint**
+- All 8 endpoints are publicly accessible.
+- No rate limiting is applied.
+- **Recommendation:** Document as intentional public API, or add authentication if these are sensitive interaction data.
+
+### Info
+
+- Redis caching is consistently applied with appropriate TTLs (10min–30min).
+- Pagination is included in search endpoints.
+- The `stats/{card_id}` endpoint returns zeros for missing cards rather than 404 — reasonable design choice.
+
+---
+
+## 8. `games/router.py` — Game Management Router
+
+### Status: ⚠️ FAIL
+
+### Endpoints
+| Method | Path | Response Model | Auth Required |
+|---|---|---|---|
+| GET | `/games/` | `List[GameResponse]` | ✅ |
+| POST | `/games/` | `GameResponse` | ✅ |
+| GET | `/games/{game_id}` | `GameResponse` | ✅ |
+| POST | `/games/{game_id}/join` | dict | ✅ |
+| POST | `/games/{game_id}/leave` | dict |
+| POST | `/games/{game_id}/start` | dict |
+| POST | `/games/{game_id}/end` | dict |
+
+### Critical Issues
+
+**C-01: `list_games` and `get_game` are stub/mock implementations**
+- `list_games` always returns `[]` without querying any database.
+- `get_game` returns a hardcoded mock response regardless of `game_id`.
+- **Impact:** These endpoints are non-functional. Any client relying on them will get incorrect data.
+- **Recommendation:** Either implement proper database queries or mark these as TODO with appropriate error responses.
+
+### Warnings
+
+**W-01: Join/Leave/Start/End endpoints have no response model**
+- All 4 mutation endpoints return raw dicts instead of typed response models.
+- **Recommendation:** Create a `GameActionResponse` schema.
+
+**W-02: `get_game` does not verify game ownership or existence**
+- Returns a mock response for any `game_id` without checking if the game actually exists.
+- No authorization check beyond the general `get_current_user` dependency.
+- **Recommendation:** Implement proper game lookup and ownership verification.
+
+### Info
+
+- `create_game` correctly verifies user existence before creating.
+- `GameCreate` schema is properly used for the create endpoint.
+- The router imports `User` model but only for verification in `create_game`.
+
+---
+
+## 9. `admin.py` — Admin Router
+
+### Status: ✅ PASS
+
+### Endpoints
+| Method | Path | Response Model | Auth Required |
+|---|---|---|---|
+| GET | `/admin/users` | `List[dict]` | ✅ (admin/judge) |
+| GET | `/admin/bans` | `List[BanResponse]` | ✅ (admin/judge) |
+| POST | `/admin/bans` | `BanResponse` | ✅ (admin/judge) |
+| POST | `/admin/bans/{ban_id}/unban` | dict | ✅ (admin/judge) |
+| GET | `/admin/logs` | `List[dict]` | ✅ (admin/judge) |
+| POST | `/admin/audit` | dict | ✅ (admin/judge) |
+
+### Info
+
+- All endpoints correctly enforce admin/judge privilege checks.
+- Ban creation properly links to user and sets moderator name.
+- Unban operation correctly updates both Ban and User records.
+- Audit logging captures admin actions with target user and details.
+
+---
+
+## 10. `rooms.py` — Room Management Router
+
+### Status: ✅ PASS
+
+### Endpoints
+| Method | Path | Response Model | Auth Required |
+|---|---|---|---|
+| GET | `/rooms/` | `List[RoomResponse]` | ✅ |
+| GET | `/rooms/{room_id}` | `RoomResponse` | ✅ |
+| POST | `/rooms/` | dict | ✅ (admin/judge) |
+| PATCH | `/rooms/{room_id}` | dict | ✅ (admin/judge) |
+| DELETE | `/rooms/{room_id}` | dict | ✅ (admin/judge) |
+
+### Info
+
+- CRUD operations are complete for rooms.
+- Admin-only write operations are properly enforced.
+- Room name uniqueness is checked before creation.
+- `RoomResponse` schema matches model fields.
+
+---
+
+## 11. `refresh.py` — MTGJSON Data Refresh Router
+
+### Status: ⚠️ FAIL
+
+### Endpoints
+| Method | Path | Response Model | Auth Required |
+|---|---|---|---|
+| POST | `/mtgjson/refresh` | dict | ✅ (admin) |
+| GET | `/mtgjson/status` | dict | ✅ (admin) |
+| POST | `/mtgjson/verify` | dict | ✅ (admin) |
+
+### Critical Issues
+
+**C-01: `/status` and `/verify` endpoints missing `db` dependency**
+- `get_refresh_status` and `verify_files` do not accept `db: AsyncSession = Depends(get_db)`.
+- If `MTGJSONManager.get_health_status()` or `verify_files()` need database access, these endpoints will fail.
+- **Impact:** Potential runtime error if the manager methods require a database session.
+- **Recommendation:** Add `db` dependency or verify that the manager methods don't need it.
+
+### Warnings
+
+**W-01: No response model on any endpoint**
+- All 3 endpoints return raw dicts without `response_model`.
+- **Recommendation:** Create response schemas for consistency.
+
+---
+
+## 12. `user_data.py` — User Data Router
+
+### Status: ⚠️ FAIL

+### Critical Issues
+
+**C-01: `create_deck_version` verifies user against `User` table instead of deck ownership**
+- The endpoint checks `select(User).where(User.id == user_id)` which will always succeed for any authenticated user.
+- It does NOT verify that the user owns the deck being versioned.
+- **Impact:** Any authenticated user can create versions for any deck.
+- **Recommendation:** Add a deck ownership check (e.g., query the deck's `user_id` field).
+
+**C-02: `get_game_replays` has ambiguous join condition**
+- `conditions.append(ReplayPlayer.user_id == user_id)` — the `user_id` column exists in both `GameReplay` (via ReplayPlayer join) and `ReplayPlayer`.
+- SQLAlchemy may raise `AmbiguousForeignKeysError` or join against the wrong table.
+- **Recommendation:** Use explicit table references: `ReplayPlayer.user_id == user_id` is correct, but the join should be explicit: `stmt = stmt.join(ReplayPlayer)`.
+
+**C-03: `update_user_statistics` has no user ownership verification**
+- The endpoint accepts `user_id` as a query parameter and updates statistics for any user.
+- Any authenticated user can modify another user's statistics.
+- **Recommendation:** Either restrict to self-update or add admin check.
+
+### Warnings
+
+**W-01: `get_deck_versions` returns wrong response structure**
+- `DeckVersionListResponse` expects `versions: List[DeckVersionResponse]`, `total: int`, `page: int`, `page_size: int`, `total_pages: int`.
+- But the endpoint wraps the list in `[SessionCleanupResponse(...)]` for sessions — wait, that's the sessions endpoint.
+- Actually, `get_deck_versions` correctly returns `DeckVersionListResponse` with proper pagination fields. **This is correct.**
+
+**W-02: `get_user_groups` and `get_user_networks` add `member_count` to response**
+- `GroupResponse` and `NetworkResponse` schemas include `member_count: int = 0` as a default, so this is actually valid.
+- **No issue here** — the schemas already account for this field.
+
+**W-03: `send_group_message` manually constructs response instead of using `model_validate`**
+- Inconsistent with other endpoints that use `model_validate`.
+- **Recommendation:** Use `GroupChatMessageResponse.model_validate(message)` for consistency, or keep manual construction if sender_username needs special handling.
+
+**W-04: `add_replay_player` and `add_network_member` return raw dicts**
+- These endpoints return `{"message": ..., "player_id": ...}` instead of typed response models.
+- **Recommendation:** Create response schemas.
+
+**W-05: `get_replay_players` returns `List[dict]` instead of typed response**
+- **Recommendation:** Create a `ReplayPlayerResponse` schema.
+
+### Info
+
+- Extensive CRUD coverage across sessions, decks, replays, outcomes, statistics, collection, wishlist, groups, networks, preferences, and activity logs.
+- Owner verification is consistently applied on collection, wishlist, and preference endpoints.
+- Group and network admin/owner checks are properly implemented.
+- Pagination is consistently applied across list endpoints.
+- `get_user_groups` correctly filters to groups where the user is a member using subquery.

+## Cross-Cutting Issues
+
+### Authentication/Authorization
+
+| Issue | Severity | Affected Routers |
+|---|---|---|
+| No auth on card_router endpoints | Warning | `card_router.py` |
+| No auth on interactions endpoints | Warning | `interactions.py` |
+| `update_user_statistics` allows updating any user | Critical | `user_data.py` |
+| `create_deck_version` doesn't verify deck ownership | Critical | `user_data.py` |
+
+### Response Model Consistency
+
+| Issue | Count | Affected Routers |
+|---|---|---|
+| Endpoints returning `dict` instead of typed model | 12 | `card_import.py`, `card_router.py`, `interactions.py`, `games/router.py`, `refresh.py`, `user_data.py` |
+
+### Database Session Consistency
+
+| Issue | Affected Routers |
+|---|---|
+| Missing `db` dependency | `refresh.py` |
+| Cross-database query (mtg_get_db for UserDeck) | `card_router.py` |
+
+### Path Prefix Consistency
+
+| Issue | Affected Routers |
+|---|---|
+| Double-prefix conflict (`/api/api/cards/...`) | `card_router.py` + `main.py` |
+| Inconsistent prefix patterns (some routers define internal prefix, some don't) | `card_router.py`, `interactions.py`, `refresh.py` |
+
+---
+
+## Recommendations (Priority Order)
+
+### P0 — Fix Immediately (Blocking)
+
+1. **Fix `card_router.py` double-prefix**: Remove `prefix="/api/cards"` from the router definition in `card_router.py` since `main.py` already mounts it at `prefix="/api"`. This breaks all 6 card search endpoints.
+
+2. **Fix `card_router.py` cross-database query**: Change `suggest_cards_endpoint` to use `get_db` instead of `mtg_get_db` for the `UserDeck` check.
+
+3. **Fix `user_data.py` `create_deck_version` ownership check**: Add deck ownership verification before allowing version creation.
+
+4. **Fix `user_data.py` `update_user_statistics` authorization**: Add ownership or admin check.
+
+### P1 — Fix Soon (Significant Impact)
+
+5. **Add response models to all endpoints returning `dict`**: Create proper Pydantic schemas for `card_import.py`, `interactions.py`, `games/router.py`, `refresh.py`, and `user_data.py` endpoints that currently return raw dicts.
+
+6. **Fix `games/router.py` stub implementations**: Either implement proper database queries for `list_games` and `get_game`, or return appropriate error responses.
+
+7. **Fix `refresh.py` missing `db` dependency**: Add `db` parameter to `/status` and `/verify` endpoints.
+
+8. **Fix `interactions.py` SQL injection risk**: Use parameterized queries or whitelists for filter values.
+
+### P2 — Improve (Nice to Have)
+
+9. **Standardize prefix pattern**: Decide whether routers should define their own prefixes or rely on `main.py` mounting. Apply consistently.
+
+10. **Add authentication to public endpoints**: Document why `card_router.py` and `interactions.py` are public, or add rate limiting.
+
+11. **Fix `auth.py` token retrieval**: Consider using Bearer token header instead of query parameter for `/auth/me`.
+
+12. **Add temp file cleanup in `card_import.py`**: Use context manager or finally block.
