not stored, not pinned, version taken and refused kind (moved here from the builder);
FailedUntilChanged keeps an unpinned upstream or a taken version from rebuilding in a
loop, while a failed push is built again.
A bundle or archive names its artifact-store blob, an image or upstream copy the
registry's reference to its digest (L1), a package name@version; Referenced names
the artifacts without one, since the controller delivers only from a key with all.
