A model's revision is published by administration and checked against on
every inference request. Those were computed by separate code: the
request path resolves through the loader, while each publisher hashed
whatever ModelConfig it happened to hold. By then SetDefaults had folded
in the GGUF guess and app-level options, so the published value was one
no request would ever carry and the model became unroutable until the
row was deleted by hand.
Fixing the publishers one at a time did not hold. Three rounds each
found another: the startup resync, then a saved edit and a toggle, then
a rename and the peer-change path.
ModelConfigLoader.RevisionFor is now the only way to obtain a revision,
and the raw hash is unexported, so a caller outside this package cannot
hash a config it holds. A publisher and a request agree by construction
rather than by two implementations happening to match.
The request path no longer falls back to hashing its merged config
either: an unstamped config is routed without a revision rather than
with a wrong one.
