mesh-controller#259 fixes while-stopped to name the container as the machine
knows it — `distribution.store`, not `store`. Until that controller is the
one composing, novox refuses its whole declaration and takes nothing at all.
The step comes out; deletion stays on, already applied and harmless on its
own. A collect step without its window would be worse than none: garbage
collection against a live registry can sweep a blob a build is pushing.
Put back once the fixed controller is deployed and stays.
