-# MTG Online Web Application
+# MTG Online Backend
 
-A modern web-based implementation of the MTG Online multiplayer Magic: The Gathering platform.
+A Python FastAPI application that processes Magic: The Gathering card data from [MTGJSON](https://mtgjson.com/) and stores it in PostgreSQL, with Redis for caching.
 
-## Features
+## Overview
 
-- **User Authentication**: Secure JWT-based authentication with bcrypt password hashing
-- **Deck Building**: Full-featured deck editor with import/export in multiple formats
-- **Real-Time Multiplayer**: WebSocket-based game server for live gameplay
-- **Protocol Compatibility**: Compatible with MTG Online protocol buffer messages
-- **Card Database**: Integration with MTJSON for comprehensive card data
-- **Admin Tools**: Comprehensive moderation and administration dashboard
+This project provides a backend API for a Magic: The Gathering Online platform. It downloads and processes MTGJSON v5 dataset dumps, loads them into a PostgreSQL database, and exposes REST endpoints for card data, user authentication, deck management, and game state.
 
-## Tech Stack
+### Key Features
 
-- **Backend**: Python 3.12, FastAPI, SQLAlchemy (async), PostgreSQL
-- **Frontend**: React, TypeScript, Zustand (coming soon)
-- **Game Server**: WebSocket with real-time state synchronization
-- **Authentication**: JWT tokens with bcrypt password hashing
-- **Database**: PostgreSQL with async driver (asyncpg)
-- **Protocol**: Protocol buffer message compatibility
+- **MTGJSON Data Pipeline** — Downloads `AllPrintings.psql`, `AllIdentifiers.json`, `Keywords.json`, `CardTypes.json`, and `AllDeckFiles.zip` from MTGJSON v5 on startup or via a `POST /refresh` endpoint.
+- **Dual PostgreSQL** — Two databases: `mtgonline` for the application (users, decks, auth) and `mtgdata` for MTG card data.
+- **Redis Caching** — Used for card lookup caching and interaction pipeline state.
+- **REST API** — `/docs` (Swagger) available at runtime.

+└── README.md
+```
+
+### 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.
+
+## Quick Start
 
 ### Prerequisites
 
 - Docker and Docker Compose
-- Python 3.12+ (for development)
-- PostgreSQL 14+ (if running without Docker)
-- Redis (optional, for caching)
-- **MTGJSON data files** (see below)
 
-### Installation
-
-1. **Clone the repository**
+### Run the Stack
 
 ```bash
-git clone https://github.com/yourusername/mtgonline-web.git
-cd mtgonline-web
+cd /home/wall-o/projects/mtgonline
+
+# Start all services (Postgres x2, Redis, Backend)
+docker compose -f docker-compose.dev.yml up -d
+
+# View logs
+docker compose -f docker-compose.dev.yml logs -f backend
 ```
 
-2. **Configure environment**
+The backend will automatically download MTGJSON data on first startup (this may take several minutes).
+
+### Access
+
+| Service        | Address             |
+|---------------|---------------------|
+| Backend API   | `http://localhost:5555`  |
+| Swagger Docs  | `http://localhost:5555/docs` |
+| Health Check  | `http://localhost:5555/health` |
+| PostgreSQL (app)  | `localhost:5432`    |
+| PostgreSQL (MTG)  | `localhost:5433`    |
+| Redis         | `localhost:6379`    |
+
+### Manual Data Refresh
 
 ```bash
-cp .env.example .env
-# Edit .env with your configuration
+# Trigger a manual MTGJSON refresh
+curl -X POST http://localhost:5555/refresh
 ```
 
-3. **Prepare MTGJSON data files**
+## Environment Variables
 
-The application requires MTGJSON data files. You have two options:
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `DATABASE_URL` | `postgresql+asyncpg://mtgonline_user:mtgonline_password@postgres:5432/mtgonline` | Primary database connection |
+| `MTG_DATABASE_URL` | `postgresql+asyncpg://mtgonline_user:mtgonline_password@mtgdata:5432/mtgdata` | MTG data database connection |
+| `REDIS_URL` | `redis://redis:6379` | Redis connection |
+| `DATA_DIR` | `/app/data` | Directory for MTGJSON files |
+| `DEBUG` | `False` | Enable debug logging |
 
-**Option A: Download from MTGJSON (recommended)**
+## Docker Cleanup
 
 ```bash
-# Create data directory
-mkdir -p data
+# Stop and remove all containers
+docker compose -f docker-compose.dev.yml down
 
-# Download required files from MTGJSON
-# See scripts/download-mtgjson.sh for automated download
-bash scripts/download-mtgjson.sh
-```
-
-**Option B: Provide your own JSON files**
-
-Place these files in the `data/` directory:
-- `AllSetFiles/` (directory containing set JSON files)
-- `AllPrintings.json`
-- `AllIdentifiers.json`
-- `CardTypes.json`
-- `DeckList.json`
-- `Keywords.json`
-- `SetList.json`
-
-### Running with Docker (recommended)
-
-```bash
-# Copy the data directory to a volume mount path
-mkdir -p ~/mtg-data
-cp -r data/* ~/mtg-data/
-
-# Start the application
-sudo docker compose up -d
-```
-
-The backend container will automatically process the JSON files from the mounted volume and populate the database.

-```
-
-
-## Docker Deployment
-
-### 1. Prepare the Data Directory
-
-Create a directory on your host machine to store the MTGJSON files:
-
-```bash
-mkdir -p ~/mtg-data
-cp -r data/* ~/mtg-data/
-```
-
-### 2. Configure Environment
-
-```bash
-cp .env.example .env
-# Edit .env with your configuration
-```
-
-### 3. Mount and Start
-
-```bash
-# Start with data directory mounted (Linux/macOS)
-sudo docker compose up -d
-
-# The data directory is automatically mounted to /app/data in the backend container
-# Alternatively, specify a custom path:
-sudo docker compose up -d --build
-```
-
-The backend will:
-- Detect the JSON files in the mounted volume
-- Upsert all data into the PostgreSQL database
-- Start the FastAPI application
-
-### 4. Verify
-
-```bash
-# Check backend logs
-docker compose logs -f backend
-
-# Test health endpoint
-curl http://localhost:8000/health
-```
-
-### Updating Data
-
-When MTGJSON releases updates:
-1. Copy new `.json` files to `~/mtg-data/`
-2. The backend will automatically process new files on next startup
-3. Or trigger a manual refresh via `/refresh` endpoint
-
-## Development
-
-### Run Locally
-
-```bash
-cd backend
-pip install -r requirements.txt
-python -m uvicorn app.main:app --reload --host 0.0.0.0 --port 8000
-```
-
-### Run Tests
-
-```bash
-cd backend
-pytest
-```

+# MTG Online Backend
+
+Python FastAPI application for processing MTGJSON card data and managing the MTG Online platform backend.
+
+## Architecture
+
+### Core Components
+
+The backend consists of several key layers:
+
+**Core Layer** (`app/core/`)
+- `settings.py` — Application configuration using pydantic-settings with environment variable overrides
+- `database.py` — Dual PostgreSQL engine setup (mtgonline app DB + mtgdata MTG cards DB)
+- `redis_client.py` — Redis connection and caching utilities
+
+**Models** (`app/models/`)
+- `models.py` — SQLAlchemy ORM models for application data (users, decks, auth)
+- `mtg_models.py` — ORM models for MTG card data
+
+**Services** (`app/services/`)
+- `mtgjson_manager.py` — Primary MTGJSON data pipeline (download, unzip, upsert)
+- `mtgjson_downloader.py` — HTTP client for MTGJSON API
+- `mtgjson_loader.py` — Data loading and transformation
+- `mtgjson_uploader.py` — Database upsert operations
+- `card_database.py` — Card data access layer
+- `game_server.py` — Game state management
+- `deck_parser.py` — Deck list parsing and validation
+
+**Routers** (`app/routers/`)
+- `auth.py` — JWT authentication endpoints
+- `users.py` — User management
+- `decks.py` — Deck CRUD operations
+- `rooms.py` — Game room management
+- `games.py` — Game state endpoints
+- `admin.py` — Admin tools
+- `card_router.py` — MTG card data API
+- `interactions.py` — Card interaction engine
+- `refresh.py` — MTGJSON data refresh endpoint
+- `ws.py` — WebSocket support
+
+**Schemas** (`app/schemas/`)
+- `schemas.py` — Pydantic models for request/response validation
+- `proto_messages.py` — Protocol buffer message definitions
+- `protocol_constants.py` — MTG protocol constants
+
+### Data Flow
+
+```
+MTGJSON API (https://mtgjson.com/api/v5/)
+    ↓ download
+MTGJSON files (AllPrintings.psql, AllIdentifiers.json, etc.)
+    ↓ load/transform
+PostgreSQL (mtgdata database)
+    ↓ query
+REST API / Swagger Docs
+```
+
+## Database Setup
+
+### Primary Database (mtgonline)
+- **Purpose**: Application data (users, decks, auth tokens)
+- **Connection**: `postgresql+asyncpg://mtgonline_user:mtgonline_password@postgres:5432/mtgonline`
+- **Port**: 5432 (internal), 5432:5432 (host)
+
+### MTG Data Database (mtgdata)
+- **Purpose**: MTG card data, sets, refresh logs
+- **Connection**: `postgresql+asyncpg://mtgonline_user:mtgonline_password@mtgdata:5432/mtgdata`
+- **Port**: 5432 (internal), 5433:5432 (host)
+- **Tables**:
+  - `mtg_sets` — Card sets metadata
+  - `mtg_cards` — Individual card data
+  - `mtg_refresh_log` — Refresh history and status
+
+### Redis
+- **Purpose**: Caching, session management
+- **Connection**: `redis://redis:6379`
+- **Port**: 6379 (internal), 6379:6379 (host)
+
+## MTGJSON Data Pipeline
+
+### Downloaded Files
+
+The backend downloads these files from MTGJSON v5:
+- `AllPrintings.psql` — Main card data (PostgreSQL format)
+- `AllIdentifiers.json` — Card identifiers (Multiverse, Scryfall, etc.)
+- `Keywords.json` — Card keywords
+- `CardTypes.json` — Card type definitions
+- `AllDeckFiles.zip` — Deck files (must be unzipped)
+
+### Refresh Logic
+
+1. **On Startup**: Checks `mtg_refresh_log` for existing data
+2. **If No Data**: Downloads and loads all MTGJSON files (may take minutes)
+3. **Manual Refresh**: `POST /refresh` endpoint triggers immediate reload
+4. **Logging**: All refreshes logged to `mtg_refresh_log` with status, timing, and counts
+

+
+## 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 psql -U mtgonline_user mtgdata < /path/to/scripts/init-mtgdata.sql`
+- Check tables: `docker exec mtgdata psql -U mtgonline_user mtgdata -c "\dt"`

-# MTG Online Backend - Project State
-
-## Project Overview
-A Python FastAPI backend service for MTG Online (Magic: The Gathering) that integrates with MTGJSON data and provides APIs for deck management, game rooms, and card data.
-
-## Current Status: Ready for Deployment
-
-### Completed Steps
-1. ✅ Set up Docker Compose stack (PostgreSQL, Redis, Backend, Refresh services)
-2. ✅ Clean up corrupted MTGJSON data files
-3. ✅ Downloaded fresh MTGJSON data from API
-4. ✅ Simplified MTGJSON data management service
-5. ✅ Updated database schema to support all JSON data
-6. ✅ Fixed directory naming issues
-7. ✅ Rebuilt and redeployed backend
-
-### Next Steps
-- Verify backend health and database connectivity
-- Test the refresh cycle
-- Confirm all MTGJSON data is properly stored
