feat: SQL=postgres, nginx+certbot, MQTT split, ML stacks, gitea HTTPS-only, gemaal1 site Round-2 changes locking in scaffold-phase decisions and adding ML/notebook stacks. Locked decisions - sql: postgres 16-alpine (was TBD); init.d/ mount for per-app DB provisioning - nginx-proxy: stock nginx + certbot sidecar (was nginx:alpine TODO). Chose stock over nginxproxy/nginx-proxy because stream{} is required for MQTT-TLS reverse-proxy on tcp/8883 to rabbitmq:1883. - gitea: HTTPS-only (DISABLE_SSH=true). No SSH port published. MQTT split - Remove stacks/mqtt placeholder. - Add stacks/rabbitmq — general-purpose broker (AMQP + MQTT plugin), used at both cloud and edge. External MQTT clients reach cloud broker via nginx stream-proxy on 8883. - Add stacks/mosquitto — reserved for the FROST (SensorThings) stack only. Cloud-only. Internal to its own stack; no external ingress. ML / notebooks (cloud-only) - stacks/mlflow — experiment tracking + model registry. Postgres backend on sql stack; local volume for artifacts (S3/MinIO is a TODO). - stacks/jupyterhub — multi-user notebook server. DockerSpawner via mounted docker.sock; users spawn into cloud-app network so they can reach mlflow, influxdb (via grafana), rabbitmq. Sites - sites/gemaal1 — first edge deployment scaffold. Site-local override template for binding nginx to PLANT_LAN_IP. Docs - README + docs/architecture.md updated: stacks table now lists 15 stacks, ingress + attachment tables reflect mlflow/jupyterhub, TLS strategy section locked, MQTT-split section added, Gitea HTTPS-only noted.

# rabbitmq
General-purpose message broker. AMQP for app-to-app messaging; MQTT plugin for external MQTT-TLS clients (fronted by nginx-proxy stream block).
Used at both cloud and edge. The `mosquitto` stack is reserved for the FROST SensorThings stack only — do not confuse the two.
- **Network**: `app` — no published port
- **External MQTT** clients reach `nginx-proxy:8883` (cloud) which stream-proxies to `rabbitmq:1883` internally. Edge brokers are internal-only.
- **Management UI**: port 15672 → reverse-proxied through nginx-proxy
- **Plugins to enable** in `config/enabled_plugins`:
```
[rabbitmq_management, rabbitmq_mqtt, rabbitmq_web_mqtt].
```
- **TODO**:
- ACL policies
- VHost layout (cloud-bus, plant-buses, ml-bus)
- Shovel/federation to `mosquitto` if FROST needs MQTT bridge to general broker
