route-proxy from plans dialled every route at the software's own port: gitea at 127.0.0.1:3000 (published at 20000) and grafana on ace at 3000 (published at 20012), and public sites answered 502. The proxy already reaches a module beside it over loopback and one elsewhere at the plan's address; the plan now carries the assigned port, and a test composes the plan with the SDK and reads it as the proxy does, so the two cannot drift again. The controller, NATS-native: no piece moves; route-proxy only.
