The composer finds a listen's machine port in a container mapping that names
it on either side (MachineSide). The program's listen 5000 matched the
registry container's inner 5000 in 127.0.0.1:5001:5000, so the store's address
became the container's loopback side and the program's own port was never
opened: the move to 83cd1a3d on 2026-11-08 23:25 UTC cut the artifact store off
(issue 1966 note 109). The program now binds 5100, where every machine fetches
(the artifact-store alias and the seats' reach agree), and the container serves
5001 inside and out. A row holds that no container names 5100.

An http probe of /v2/ said only that a port answered; design 51 asks the health check to call versions per seat and
probe the read side each minute, naming the program when it is down, from outside its process. registry_health asks
versions of each seat through the program's port, writes the read-side finding while it fails and clears it after.
