```

chore: refactor logging module, update genesis timestamp, remove model relationships, and reorganize routers

- Rename logging.py to logger.py and update import paths in poa.py and main.py
- Update devnet genesis timestamp to 1766828620
- Remove SQLModel Relationship declarations from Block, Transaction, and Receipt models
- Add SessionDep type alias and get_session dependency in coordinator-api deps
- Reorganize coordinator-api routers: replace explorer/registry with exchange, users, marketplace

+# AITBC Domain Deployment Guide
+
+## Overview
+
+Deploy AITBC services to your existing domain: **https://aitbc.bubuit.net**
+
+## Service URLs
+
+- **Marketplace**: https://aitbc.bubuit.net/Marketplace
+- **Trade Exchange**: https://aitbc.bubuit.net/Exchange
+- **API**: https://aitbc.bubuit.net/api
+- **Blockchain RPC**: https://aitbc.bubuit.net/rpc
+- **Admin**: https://aitbc.bubuit.net/admin
+
+## Prerequisites
+
+1. Incus access (add user to incus group):
+```bash
+sudo usermod -aG incus $USER
+# Log out and back in
+```
+
+2. Domain pointing to your server
+
+## Deployment Steps
+
+### 1. Deploy Services
+```bash
+./deploy-domain.sh
+```
+
+### 2. Configure Port Forwarding
+Forward these ports to the container IP (10.1.223.93):
+- Port 80 → 10.1.223.93:80
+- Port 443 → 10.1.223.93:443
+
+### 3. Install SSL Certificate
+```bash
+incus exec aitbc -- certbot --nginx -d aitbc.bubuit.net
+```
+
+### 4. Verify Services
+Visit the URLs to ensure everything is working.
+
+## Nginx Configuration
+
+The nginx configuration handles:
+- HTTPS redirection
+- SSL termination
+- Path-based routing
+- API proxying
+- Security headers
+
+Configuration file: `/home/oib/windsurf/aitbc/nginx-aitbc.conf`
+
+## Service Management
+
+### Check running services:
+```bash
+incus exec aitbc -- ps aux | grep python
+```
+
+### View logs:
+```bash
+incus exec aitbc -- journalctl -u aitbc-coordinator -f
+```
+
+### Restart services:
+```bash
+incus exec aitbc -- pkill -f uvicorn
+incus exec aitbc -- /home/oib/start_aitbc.sh
+```
+
+### Update nginx config:
+```bash
+incus file push nginx-aitbc.conf aitbc/etc/nginx/sites-available/aitbc
+incus exec aitbc -- nginx -t && incus exec aitbc -- systemctl reload nginx
+```
+
+## API Endpoints
+
+### Coordinator API
+- GET `/api/marketplace/offers` - List GPU offers
+- POST `/api/miners/register` - Register miner
+- POST `/api/marketplace/bids` - Create bid
+- GET `/api/marketplace/stats` - Marketplace stats
+
+### Blockchain RPC
+- GET `/rpc/head` - Get latest block
+- GET `/rpc/getBalance/{address}` - Get balance
+- POST `/rpc/admin/mintFaucet` - Mint tokens
+
+## Security Considerations
+
+1. **Firewall**: Only open necessary ports (80, 443)
+2. **SSL**: Always use HTTPS
+3. **API Keys**: Use environment variables for sensitive keys
+4. **Rate Limiting**: Configure nginx rate limiting if needed
+
+## Monitoring
+
+### Health checks:
+- https://aitbc.bubuit.net/health
+
+### Metrics:
+- https://aitbc.bubuit.net/metrics (if configured)
+
+## Troubleshooting
+
+### Services not accessible:
+1. Check port forwarding
+2. Verify nginx configuration
+3. Check container services
+
+### SSL issues:
+1. Renew certificate: `incus exec aitbc -- certbot renew`
+2. Check nginx SSL config
+
+### API errors:
+1. Check service logs
+2. Verify API endpoints
+3. Check CORS settings
+
+## Customization
+
+### Add new service:
+1. Update nginx-aitbc.conf
+2. Add service to start_aitbc.sh
+3. Restart services
+
+### Update UI:
+1. Modify HTML files in apps/
+2. Update base href if needed
+3. Restart web servers
+
+## Production Tips
+
+1. Set up monitoring alerts
+2. Configure backups
+3. Use environment variables for config
+4. Set up log rotation
+5. Monitor resource usage
