The controller pins a model's replicas to a stored revision and rejects
any request carrying a different one. Nothing ever re-derived that value
from the configuration on disk: it moved only on an edit, a gallery
install, or a peer's change broadcast. An inference request may only
establish a revision, never replace one.
So any other way for the two to diverge left the model permanently
unroutable. A configuration edited while a frontend was down lands
there, and so does a change in what the revision is computed over: an
upgrade that alters the hashed form leaves every stored revision
describing a configuration that no longer exists. The only recovery was
deleting the row by hand, which is not something a cluster should need.
Each frontend now reconciles the stored revisions against the loaded
configurations at startup and republishes the ones that disagree. Only
those: republishing quarantines every replica loaded under the old
revision, so doing it for a model that did not drift would unload a
healthy replica for nothing. A model with no stored revision has never
been served and is left for its first request to establish.
