Only backend workers subscribe to backend.list. ListBackends asked every
node that was not pending, offline or draining, so an agent worker could
only answer "no responders", which the error handling reads as a node
that has gone away. Every poll of the backends view therefore marked
each agent node unhealthy, and its next heartbeat marked it healthy
again.
While unhealthy the node is not schedulable, so this also cost agent
capacity for as long as each flap lasted.
Skip non-backend workers, as the backend-op fan-out already does for the
same reason. A backend worker that does not answer is still marked
unhealthy: that one really is gone.

The revision was computed after SetDefaults, which folds in things that
are not persisted configuration: the GGUF guess, the hardware defaults,
and app-level options such as threads.
The GGUF guess is the damaging one. It parses the model file to fill in
values like context size, and when that parse fails it falls back to a
different default. Whether a multi-gigabyte file on network storage
parses at a given moment is not a property of the configuration, so one
unchanged YAML produced two different revisions depending on when it was
read. The controller rejected every request carrying the other one, and
the model stayed unroutable until the stored value happened to match
again. This is why it never reproduced against a model directory with no
weights in it: the guess is skipped there and both values agree.
The app-level defaults are the same class of bug with a slower fuse:
changing threads in the settings UI changed every model's revision and
made every model unroutable.
The revision is now stamped when the file is parsed, before any defaults
are applied, so it is a function of the file alone.

Two code paths computed a model's revision. Inference resolves the
config through the loader, which applies SetDefaults a second time.
Everything that publishes a revision hashed the stored config instead,
with SetDefaults applied once.
SetDefaults is not idempotent for every model: it re-runs the GGUF guess
and the hardware defaults, both of which read state the stored config
does not carry. Where the two disagree, a publisher wrote a revision no
request would ever carry, and the model became unroutable the moment it
was published. On this cluster the startup resync republished one such
value and every request for that model was then rejected against it.
The publishers now resolve the revision through the loader, exactly as a
request does, so there is one definition rather than two that agree only
when SetDefaults happens to be idempotent. This covers the startup
resync, a saved config edit, and enabling or disabling a model.

quay.io redirects blob downloads to pre-signed S3/Akamai URLs that
expire after about 10 minutes. On a slow connection a multi-GiB
backend layer cannot finish inside that window, so the connection
drops mid-stream on every attempt. The retry added for #10577
restarted each attempt from byte zero, which replayed the same
failure until the budget ran out and the install failed with
"unexpected EOF".
A retry now keeps the bytes already on disk and re-requests the
blob with "Range: bytes=N-". Each request goes back to the
registry, so it gets a fresh redirect URL and auth token. The
retry budget only counts attempts that made no forward progress,
so a slow link that keeps advancing keeps downloading. A resumed
file is spliced from separate responses and bypasses the digest
check in layer.Compressed(), so the assembled file is re-verified
against the layer digest before it is trusted; on a mismatch the
download starts over through the verified reader.
Fixes#10577

The resync added in 3953448f6 ran before LoadModelConfigsFromPath, so it
read an empty loader, reconciled nothing and reported success. The
symptom was a stored revision that stayed stale across restarts while
the log showed no complaint, which is exactly what the resync was meant
to prevent.
Move the call after the configs are loaded, and refuse to treat an empty
loader as a clean run: reconciling zero models is indistinguishable from
reconciling correctly, and that is what hid the mis-ordered call.

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.

A replica row in staging or loading holds its slot, because slot
allocation counts every state except unloading. Nothing ever reclaimed
such a row: every reconciler pass and the router's eviction query filter
state = "loaded", and the per-model probe skips rows without an address,
which is exactly what a row that never finished loading has.
So a worker that dropped out mid-transfer left a row that pinned the
only replica slot for that model on that node. Scheduling then found no
free slot and eviction found nothing it was allowed to evict, and the
request failed with "no replica slot on <node> and eviction failed: all
models busy". The state persisted until an operator intervened.
The reconciler now reclaims a row stuck before serving when no load job
is driving it. Ownership is decided by the job's LastProgress heartbeat,
not by elapsed time: staging a large checkpoint legitimately runs for a
long while without touching the replica row, so a deadline would either
be a model-size cliff or reclaim a healthy transfer. That heartbeat is
the same signal job takeover already trusts. Any error reading the job
leaves the slot held, because holding one for another pass costs a
scheduling opportunity while a wrong reclaim restarts a multi-gigabyte
transfer.

A node's status comes from its HTTP heartbeat. Backend installs travel
over NATS. The two are independent, so a worker that dies stops
answering on the bus at once but stays healthy in the database until its
heartbeat ages out. Inside that window the scheduler picked a node it
could not reach, and the request failed with "no responders available"
rather than moving to a node that was up.
The scheduler now probes the node it selected and, when nothing answers,
marks it unhealthy and selects again. The demotion is what makes the
retry terminate: the next selection reads only healthy nodes. It also
tells the other frontends what this one learned, so the cluster does not
rediscover a dead worker one failed request at a time.
Only nats.ErrNoResponders counts as absent. A worker that answers slowly
stays eligible, because dropping it would cost capacity that is really
there. The probe reuses the models.running subject: a new subject would
go unanswered by workers that have not been upgraded, and every one of
them would then look dead.

the error from applying its options and Run returns it, so a process
whose state directory cannot be created reports the real cause instead
of failing later inside os.MkdirAll("") with an empty path.

process.New applies its options and discards the error they return. When
WithTemporaryStateDir could not create a directory, StateDir stayed
empty and every later option went unapplied, so the failure surfaced
from Run as "mkdir : no such file or directory" naming no path.
That message cost a full day of diagnosis on a worker whose volume was
full: the real errno was ENOSPC and nothing reported it.
The loader now creates the directory itself and returns the underlying
error with the path attached.

A request that carries a file stages it to the worker, which writes it
under its staging directory. Nothing removed it afterwards. The frontend
expires ephemeral keys from object storage, but that sweep never covered
a worker's local disk, so every image, audio clip and video a worker
ever served stayed on it.
One worker had accumulated 175 request directories over three months.
The volume reached 100 percent, and from that point every backend start
failed because the process manager could not create a state directory.
The worker now sweeps its ephemeral staging directory on a timer and
once at startup, so files left by a crash are reclaimed too. Staged
model files live beside that directory and are not touched.

syncKnownUsecasesFromString rebuilds KnownUsecaseStrings by ranging
GetAllModelConfigUsecases, which is a map. Go randomizes that order per
call, and the field is part of the serialized config, so one unchanged
YAML hashed to a different config revision on every load.
A model that derives a single usecase hid the problem. One that derives
several, such as a chat model with an mmproj, alternated between as many
revisions as there are orderings. The router treats a revision it did
not establish as a config change, so requests failed with "stale model
config revision" until the stored value happened to match again.
Sorting the list makes the revision a function of the file alone.

The request middleware merges the caller's prediction parameters into
its copy of the model config. core/backend.ModelOptions then hashed
that copy, so the revision identified the request body rather than the
persisted configuration.
EstablishModelConfigRevision stores the first revision it sees and
requires an exact match afterwards. The first request after a restart
therefore pinned the model to its own temperature, top_p and stop
values, and every later request that sent different ones failed with
"stale model config revision". No config edit was involved.
The loader now stamps the revision when it materializes a config,
before any request override reaches it, and ModelOptions reads that
stamp. Model administration keeps hashing the same persisted config, so
both paths agree on one revision per configuration.
