Found by deleting the lab's registry and giving the machines a real path out:
public images fetched, the operator's own could not be fetched at all. There is
no provision for a registry credential, no manifest field, and no step in
enrolment that establishes one.
It applies to the mesh's own store too, which today asks for nothing — a
decision that has never been written down as one, and so reads as an absence.
