A want that names a node in kept-on, for an artifact its parts name, is fetched through kept-artifact of that node's build seat and
read as an object on the bus, checked against the digest; with no kept-on it is fetched from the store, and the builder's builds
are read no more (the apply hook, the fetch and the object read from bc8fbc7, its node and fingerprint from the want).

On 2026-11-08 23:25 UTC the node-engine replaced distribution's store container
and only then fetched distribution's program from the store it had just cut off:
the module was left half applied and the artifact store unreachable from every
other machine. An apply now fetches and checks every archive and process first,
as it already pulls a module's images first; one that cannot be had gates its
module, so none of its resources is replaced and none of its orphans removed.
