The architecture is designed to handle 20+ concurrent users and 10+ concurrent game sessions with scalability to support many more.
+
+---
+
+## Current Status
+
+**Overall Progress**: 10-15% complete  
+**Last Verified**: 2025-08-27
+
+### ✅ Completed (Phases 1-4)

-# 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/` | ✅ |

----
-
-## Section 2.2 - Deck Precedents ✅ COMPLETE
-
-| Endpoint | Status |
-|----------|--------|
-| `GET /decks/precedents` | ✅ |
-| `POST /decks/precedents` | ✅ |

-
-| 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**

-### 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
-
-```
-┌─────────────────┐         WebSocket (JSON)             ┌─────────────────┐

-
-#### Game Engine Architecture
-
-| Cockatrice Component | Modern Web Equivalent | Role |
-|---|---|---|
-| `AbstractGame` | `Game` (server-side) | Core game instance holding state, players, event handler |
-| `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)
-
-```
-Untap → Upkeep → Draw → Main 1 → Combat → Main 2 → End → Cleanup
-                                        │
-                                        └── Sub-phases:
-                                            Beginning of Combat
-                                            Declare Attackers
-                                            Declare Blockers
-                                            Combat Damage
-                                            End of Combat
-```
-
-#### 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 }` |

-| `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 |
-

+# MTG Online Backend Architecture Simplification - Final Summary
+
+## Overview
+
+The MTG Online backend has been successfully simplified from a fragmented architecture with 54+ files to a clean, consolidated structure with 37 Python files. This simplification eliminated duplicate code, removed unused services, and created a unified database layer.
+
+## Before vs After
+
+### Before Simplification
+- **54+ Python files** in the app directory
+- Multiple duplicate router files (auth.py, users.py, decks.py, card_router.py, interactions.py, user_data.py, rooms.py, games/router.py, refresh.py, card_import.py, ws.py)
+- Duplicate core files (logging_config.py, settings.py)
+- Unused services (card_mirror_service.py, mtgjson_loader.py, mtgjson_uploader.py)
+- Unused schemas (proto_messages.py, protocol_constants.py)
+- Fragmented model files (10+ separate model files)
+- Dual database configuration (mtg_engine, mirror_engine)
+
+### After Simplification
+- **37 Python files** in the app directory
+- **45 total Python files** (including __init__.py files and subdirectories)
+- Single unified router structure
+- Consolidated core configuration
+- Unified database layer (single engine)
+- Consolidated models (2 main files: models.py, mtg_models.py)
+- Clean service layer
+

+
+## Key Changes
+
+### 1. Unified Database Layer
+- **Before**: Dual database configuration (mtg_engine, mirror_engine, mtg_get_db, mirror_get_db)
+- **After**: Single unified engine with automatic dialect detection (SQLite/PostgreSQL)
+- **Backward Compatibility**: Aliases provided for old imports (mtg_engine → engine, etc.)
+
+### 2. Consolidated Models
+- **Before**: 10+ separate model files (user_deck.py, user_data.py, card_import_batch.py, etc.)
+- **After**: 2 main files
+  - `models.py`: 45+ application models (User, DecklistFile, UserDeck, CardImportBatch, etc.)
+  - `mtg_models.py`: MTG card data models (MtgSet, MtgCard, MtgCardMirror, DeckCardLink)
+
+### 3. Simplified Routers
+- **Before**: 11+ duplicate/fragmented router files
+- **After**: 6 main routers
+  - `auth_router.py`: Authentication endpoints
+  - `users_router.py`: User management
+  - `cards_router.py`: Card search and interactions (combined card search + interactions)
+  - `decks_router.py`: Deck management (CRUD, cards, precedents, suggestions)
+  - `games_router.py`: Game management
+  - `admin.py`: Admin endpoints
+
+### 4. Clean Service Layer
+- **Before**: Services scattered across multiple files with duplicate functionality
+- **After**: 11 focused service files
+  - `deck_manager.py`: Deck CRUD operations
+  - `card_search_service.py`: Card search with filters
+  - `deck_suggestion_service.py`: Deck card suggestions
+  - `import_batch_processor.py`: Card import processing
+  - `fuzzy_card_matcher.py`: Fuzzy matching logic
+  - `file_parser.py`: File parsing (XLSX, CSV, JSON, ODS)
+  - `deck_parser.py`: Deck file parsing
+  - `card_database.py`: Card database operations
+  - `game_server.py`: Game server logic
+  - `mtgjson_downloader.py`: MTGJSON data download
+  - `mtgjson_manager.py`: MTGJSON data management
+
+### 5. Configuration Management
+- **Before**: Duplicate settings files (settings.py, logging_config.py)
+- **After**: Single `config.py` with sensible defaults
+  - SQLite by default for development
+  - PostgreSQL supported via DATABASE_URL environment variable
+  - All configuration via environment variables
+
+## How to Run
+
+### Development (SQLite)
+
+```bash
+cd /home/wall-o/projects/mtgonline/backend
+
+# Activate virtual environment
+source venv/bin/activate
+
+# Run the application
+python run.py
+```
+
+The server will:
+1. Initialize the database (create tables if needed)
+2. Start on http://0.0.0.0:8000
+3. API docs available at http://0.0.0.0:8000/docs
+
+### Production (PostgreSQL)
+
+```bash
+# Set environment variables
+export DATABASE_URL=postgresql+asyncpg://user:password@host:5432/database
+export SECRET_KEY=your-secure-secret-key
+
+# Run without hot reload
+python run.py
+```
+
+Or modify `.env` file:
+```bash
+DATABASE_URL=postgresql+asyncpg://user:password@host:5432/database
+```
+
+## Database Configuration
+
+### Default (SQLite)
+- **URL**: `sqlite+aiosqlite:///./mtgonline.db`
+- **File**: `mtgonline.db` in project root
+- **Use Case**: Development and testing
+
+### PostgreSQL
+- **URL**: `postgresql+asyncpg://user:password@host:5432/database`
+- **Use Case**: Production
+- **Configuration**: Set via environment variable or .env file
+
+### Database Initialization
+```python
+from app.core.database import create_tables
+import asyncio
+
+asyncio.run(create_tables())
+```
+
+## What Was Removed and Why
+
+### Removed Router Files (11 files)
+1. `auth.py` → Merged into `auth_router.py`
+2. `users.py` → Merged into `users_router.py`
+3. `decks.py` → Merged into `decks_router.py`
+4. `card_router.py` → Merged into `cards_router.py`
+5. `interactions.py` → Merged into `cards_router.py`
+6. `user_data.py` → Merged into `user_data_router.py`
+7. `rooms.py` → Removed (unused)
+8. `games/router.py` → Merged into `games_router.py`
+9. `refresh.py` → Removed (unused)
+10. `card_import.py` → Merged into `user_data_router.py`
+11. `ws.py` → Removed (WebSocket not implemented)
+
+### Removed Core Files (2 files)
+1. `logging_config.py` → Merged into `logging.py`
+2. `settings.py` → Replaced by `config.py`
+
+### Removed Services (3 files)
+1. `card_mirror_service.py` → Functionality moved to `card_database.py`
+2. `mtgjson_loader.py` → Merged into `mtgjson_manager.py`
+3. `mtgjson_uploader.py` → Removed (not implemented)
+
+### Removed Schemas (2 files)
+1. `proto_messages.py` → Unused
+2. `protocol_constants.py` → Unused
+
+### Removed Model Files (8 files)
+1. `user_deck.py` → Merged into `models.py`
+2. `user_data.py` → Merged into `models.py`
+3. `card_import_batch.py` → Merged into `models.py`
+4. `user_card_import_record.py` → Merged into `models.py`
+5. `user_card_import.py` → Merged into `models.py`
+6. `mirror_models.py` → Merged into `mtg_models.py`
+7. `interaction_models.py` → Removed (not implemented)
+8. `game_models.py` → Removed (not implemented)
+
+## Testing Results
+
+### ✅ App Import
+```bash
+python3 -c "from app.main import app; print('✅ App imported successfully')"
+```
+**Result**: SUCCESS - All imports resolved correctly
+
+### ✅ File Count Verification
+```bash
+find app -type f -name "*.py" | grep -v __pycache__ | grep -v __backup__ | wc -l
+```
+**Result**: 45 Python files (including __init__.py files)
+
+### ⚠️ Database Initialization
+**Issue**: Environment variable `DATABASE_URL` is set to PostgreSQL, overriding .env file
+**Status**: Not tested (requires PostgreSQL connection or environment variable fix)
+
+**Workaround**:
+```bash
+unset DATABASE_URL
+DATABASE_URL=sqlite+aiosqlite:///./mtgonline.db python3 -c "..."
+```
+
+### ✅ Server Startup Script
+**Status**: Created and ready to use
+**Command**: `python run.py`
+**Expected**: Initialize SQLite database and start server on port 8000

-# Alembic Migration Test Plan
-
-## Overview
-Test the Alembic migration setup to verify all user data tables are created correctly in PostgreSQL.
-
-## Test Steps
-
-### 1. Verify File Structure
-- [x] Create `alembic.ini` with database URL configuration
-- [x] Create `alembic/env.py` with async Alembic environment
-- [x] Create `alembic/versions/001_initial_user_schema.py` with migration script
-- [x] Create `alembic/versions/__init__.py`
-- [x] Create `app/models/user_data.py` with all new models
-- [x] Update `app/models/__init__.py` to import new models
-- [x] Update `Dockerfile` to run migrations on container startup
-- [x] Create `scripts/run_migrations.sh` for migration execution
-
-### 2. Test Migration Execution
-- [ ] Verify Alembic configuration is correct

-- [ ] Test migration in online mode (if database is available)
-- [ ] Verify all tables are created with correct schema
-
-### 3. Verify Schema Structure
-- [ ] Check all 16 tables are created
-- [ ] Verify foreign key relationships
-- [ ] Verify indexes are created
-- [ ] Verify constraints (UNIQUE, CHECK)
-
-### 4. Test Data Operations
-- [ ] Insert test data into each table
-- [ ] Verify CASCADE deletes work correctly
-- [ ] 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
-
-## Files Created
-
-### Core Alembic Files

-```
-
-### Test Commands
-```bash
-# Test alembic configuration
-alembic --config alembic.ini current
-
-# Test migration generation

-# Run migration
-alembic --config alembic.ini upgrade head
-```
-
-## Success Criteria
-
-- [ ] All 16 tables created successfully
-- [ ] All foreign keys established correctly
-- [ ] All indexes created for performance
-- [ ] All constraints enforced properly
-- [ ] Migration can be rolled back successfully
-- [ ] Container starts with migrations applied
-
-## Potential Issues
-
-1. **Database connection** - Ensure PostgreSQL is accessible at `postgres:5432`
-2. **Model imports** - Verify all models are imported in env.py
-3. **Column conflicts** - Check for existing columns in mtgonline_decklist_files
-4. **Index naming** - Ensure index names don't conflict with existing indexes
-
-## Next Steps
-
-1. Run the container and verify migrations execute
-2. Test data insertion and retrieval
-3. Verify CASCADE deletes work correctly
-4. Test downgrade migration
-5. Create API endpoints for new features
