home-assistant: the runtime serves its code, and its provisions step is a run-once process (hq ADR 0198)
The mesh-home-assistant container goes with its Dockerfile, build bases and bus credential. The provisions step runs node on the bundle and reads the binding files where the mesh writes them, from an env-file the mesh fills because a process's env is not given ${port:…}. It still runs again when a binding it reads changes.

# home-assistant's runtime: the tool runtime, carrying this module's compiled code.

# image it RUNS in — the second must not carry a compiler. Declared in module.json's `build.on`.
