+## Happy Server (Self-Hosted Relay)
+
+Self-hosted Happy Coder relay server for lower latency and no external dependencies.
+
+### Architecture
+```
+Phone App → https://happy.htsn.io → Traefik → docker-host:3002 → Happy Server
+                                                    ↓
+                                    PostgreSQL + Redis + MinIO (local)
+```

+| PostgreSQL | docker-host | 5432 (internal) | User/session data |
+| Redis | docker-host | 6379 (internal) | Real-time events |
+| MinIO | docker-host | 9000 (internal) | File/image storage |
+| Traefik | CT 202 | 443 | SSL termination |
+
+### Configuration
+
+**Docker Compose**: `/opt/happy-server/docker-compose.yml`
+**Traefik Config**: `/etc/traefik/conf.d/happy.yaml` (on CT 202)
+**DNS**: happy.htsn.io → 70.237.94.174 (Cloudflare proxied)
+
+**Credentials**:
+- Master Secret: `3ccbfd03a028d3c278da7d2cf36d99b94cd4b1fecabc49ab006e8e89bc7707ac`

+### Quick Commands
+```bash
+# Check status
+ssh docker-host 'docker ps --filter "name=happy"'
+
+# View logs
+ssh docker-host 'docker logs -f happy-server'
+
+# Restart stack
+ssh docker-host 'cd /opt/happy-server && sudo docker-compose restart'

 ## Changelog
 
+### 2025-12-21
+
+**Happy Server Self-Hosted Relay**
+- Deployed self-hosted Happy Coder relay server on docker-host (10.10.10.206)
+- Stack includes: Happy Server, PostgreSQL, Redis, MinIO (all containerized)
+- Configured Traefik reverse proxy at https://happy.htsn.io
+- Added Cloudflare DNS record (proxied)
+- Fixed Dockerfile to include Prisma migrations on startup
+
+**Docker-host CPU Upgrade**
+- Changed VM 206 CPU from emulated to `host` passthrough
+- Fixes x86-64-v2 compatibility issues with modern binaries (Sharp, MinIO)
+- Requires: `ssh pve 'qm set 206 -cpu host'` + VM reboot
+
+**PVE Tailscale Routing Fix**
+- Fixed issue where PVE was unreachable via local network (10.10.10.120)
+- Root cause: Tailscale routing table 52 was capturing local subnet traffic
