The builder's environment said MESH_REGISTRY=127.0.0.1:${bound:artifact-store:port}
— the port taken from the binding, the host pinned to loopback. So every artifact
the mesh builds was recorded under an address that means something only on the
machine holding the registry, and nothing else in the mesh could resolve it.
Loopback is correct for exactly one reader and the builder is not special: it
already requires artifact-store, and the binding states where the provider is on
the private network. It now uses both halves of what it was given.
Invisible with one machine, which is the only shape this had been proven in. The
registry module declares that every machine pulls from it and opens its port to
the mesh for that reason, so the reference it is handed has to be one a second
machine can use.

Its account is scoped from what it emits and consumes, and it declared neither —
which is why asking for a generic module account produced one that authenticated
and could do nothing, with the refusal surfacing a layer away as a permissions
error against a queue.
Declaring the announcement is not documentation here. It is what the permission
is derived from.

The code that turns a repository into artifacts already existed and is deliberately
something a machine runs as an ordinary module rather than something the control
plane does. There was no module for it, so it could never be placed and never ran —
which is why nothing in the catalogue could be produced.
It asks for a container runtime because it builds images, requires the artifact
store because it publishes into it, and claims one per machine. Its credential
folder is mounted rather than the file, since a file mount keeps pointing at the
old contents after the mesh writes new ones.
The store is reached on the machine's own loopback: the address in a binding is
where a machine sits on the private network, and the store has to be co-located
anyway because runtimes refuse a plain-HTTP registry anywhere else.
