+# Production Deployment Guide
+
+This document describes the production deployment infrastructure and procedures for the abaci.one web application.
+
+## Infrastructure Overview
+
+### Production Server
+- **Host**: `nas.home.network` (Synology NAS DS923+)
+- **Access**: SSH access required
+  - Must be connected to network at **730 N. Oak Park Ave**
+  - Server is not accessible from external networks
+- **Project Directory**: `/volume1/homes/antialias/projects/abaci.one`
+
+### Docker Configuration
+- **Docker binary**: `/usr/local/bin/docker`
+- **Docker Compose binary**: `/usr/local/bin/docker-compose`
+- **Container name**: `soroban-abacus-flashcards`
+- **Image**: `ghcr.io/antialias/soroban-abacus-flashcards:latest`
+
+### Auto-Deployment
+- **Watchtower** monitors and auto-updates containers
+- **Update frequency**: Every **5 minutes**
+- Watchtower pulls latest images and restarts containers automatically
+- No manual intervention required for deployments after pushing to main
+
+## Database Management
+
+### Location
+- **Database path**: `data/sqlite.db` (relative to project directory)
+- **WAL files**: `data/sqlite.db-shm` and `data/sqlite.db-wal`
+
+### Migrations
+- **Automatic**: Migrations run on server startup via `server.js`
+- **Migration folder**: `./drizzle`
+- **Process**:
+  1. Server starts
+  2. Logs: `🔄 Running database migrations...`
+  3. Drizzle migrator runs all pending migrations
+  4. Logs: `✅ Migrations complete` (on success)
+  5. Logs: `❌ Migration failed: [error]` (on failure, process exits)
+
+### Nuke and Rebuild Database
+If you need to completely reset the production database:
+
+```bash
+# SSH into the server
+ssh nas.home.network
+
+# Navigate to project directory
+cd /volume1/homes/antialias/projects/abaci.one
+
+# Stop the container
+/usr/local/bin/docker-compose down
+
+# Remove database files
+rm -f data/sqlite.db data/sqlite.db-shm data/sqlite.db-wal
+
+# Restart container (migrations will rebuild DB)
+/usr/local/bin/docker-compose up -d
+
+# Check logs to verify migration success
+/usr/local/bin/docker logs soroban-abacus-flashcards | grep -E '(Migration|Starting)'
+```
+
+## CI/CD Pipeline
+
+### GitHub Actions
+When code is pushed to `main` branch:
+
+1. **Workflows triggered**:
+   - `Build and Deploy` - Builds Docker image and pushes to GHCR
+   - `Release` - Manages semantic versioning and releases
+   - `Verify Examples` - Runs example tests
+   - `Deploy Storybooks to GitHub Pages` - Publishes Storybook
+
+2. **Image build**:
+   - Built image is tagged as `latest`
+   - Pushed to GitHub Container Registry (ghcr.io)
+   - Typically completes within 1-2 minutes
+
+3. **Deployment**:
+   - Watchtower detects new image (within 5 minutes)
+   - Pulls latest image
+   - Recreates and restarts container
+   - Total deployment time: ~5-7 minutes from push to production
+
+## Manual Deployment Procedures
+
+### Force Pull Latest Image
+If you need to immediately deploy without waiting for Watchtower:
+
+```bash
+ssh nas.home.network "cd /volume1/homes/antialias/projects/abaci.one && /usr/local/bin/docker-compose pull && /usr/local/bin/docker-compose up -d"
+```
+
+### Check Container Status
+```bash
+ssh nas.home.network "/usr/local/bin/docker ps | grep -E '(soroban|abaci)'"
+```
+
+### View Logs
+```bash
+# Recent logs
+ssh nas.home.network "/usr/local/bin/docker logs --tail 100 soroban-abacus-flashcards"
+
+# Follow logs in real-time
+ssh nas.home.network "/usr/local/bin/docker logs -f soroban-abacus-flashcards"
+
+# Search for specific patterns
+ssh nas.home.network "/usr/local/bin/docker logs soroban-abacus-flashcards" | grep -i "error"
+```
+
+### Restart Container
+```bash
+ssh nas.home.network "cd /volume1/homes/antialias/projects/abaci.one && /usr/local/bin/docker-compose restart"
+```
+
+## Deployment Script
+
+The project includes a deployment script at `nas-deployment/deploy.sh` for manual deployments.
+
+## Troubleshooting
+
+### Common Issues
+
+#### 1. Migration Failures
+**Symptom**: Container keeps restarting, logs show migration errors
+
+**Solution**:
+1. Check migration files in `drizzle/` directory
+2. Verify `drizzle/meta/_journal.json` is up to date
+3. If migrations are corrupted, may need to nuke database (see above)
+
+#### 2. Container Not Updating
+**Symptom**: Changes pushed but production still shows old code
+
+**Possible causes**:
+- GitHub Actions build failed - check workflow status with `gh run list`
+- Watchtower not running - check with `docker ps | grep watchtower`
+- Image not pulled - manually pull with `docker-compose pull`
+
+**Solution**:
+```bash
+# Force pull and restart
+ssh nas.home.network "cd /volume1/homes/antialias/projects/abaci.one && /usr/local/bin/docker-compose pull && /usr/local/bin/docker-compose up -d"
+```
+
+#### 3. Missing Database Columns
+**Symptom**: Errors like `SqliteError: no such column: "column_name"`
+
+**Cause**: Migration not registered or not run
+
+**Solution**:
+1. Verify migration exists in `drizzle/` directory
+2. Check migration is registered in `drizzle/meta/_journal.json`
+3. If migration is new, restart container to run migrations
+4. If migration is malformed, fix it and nuke database
+
+#### 4. API Returns Unexpected Response
+**Symptom**: Client shows errors but API appears to work
+
+**Debugging**:
+1. Test API directly with curl: `curl -X POST 'https://abaci.one/api/arcade/rooms' -H 'Content-Type: application/json' -d '...'`
+2. Check production logs for errors
+3. Verify container is running latest image:
+   ```bash
+   ssh nas.home.network "/usr/local/bin/docker inspect soroban-abacus-flashcards --format '{{.Created}}'"
+   ```
+4. Compare with commit timestamp: `git log --format="%ci" -1`
+
+## Environment Variables
+
+Production environment variables are configured in the docker-compose.yml file on the server. Common variables:
+
+- `NEXT_PUBLIC_URL` - Base URL for the application
+- `DATABASE_URL` - SQLite database path
+- Additional variables may be set in `.env.production` or docker-compose.yml
+
+## Network Configuration
+
+- **Reverse Proxy**: Traefik
+- **HTTPS**: Automatic via Traefik with Let's Encrypt
+- **Domain**: abaci.one
+- **Exposed Port**: 3000 (internal to Docker network)
+
+## Security Notes
+
+- Production database contains user data and should be handled carefully
+- SSH access is restricted to local network only
+- Docker container runs with appropriate user permissions
+- Secrets are managed via environment variables, not committed to repo
