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.

Picks up "surface option errors instead of discarding them". New records
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.
LocalAI already resolves that directory itself, so this covers the other
process.New call sites rather than changing behaviour on the backend
start 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.

"stale model config revision" reported only that two hashes differed.
It named neither, so an operator could not tell an edited configuration
from a revision that is not reproducible for one unchanged file, and the
failing value appears in no table.
The error now carries the revision the request brought and the one the
controller holds. It still wraps ErrStaleModelConfigRevision, so callers
that classify the error keep working.

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.

* fix(vram): persist remote probe metadata
The startup warmer repeated remote size and GGUF metadata probes after every restart because both caches lived only in memory. Store successful HTTP probes for 24 hours so frequent restarts reuse the prior results.

* docs(blog): add the 4.9 release post and its demo clips
The 4.9 cycle changed how you authenticate, how chat handles a history
that no longer fits, and where models and backends live in the UI. The
release notes list every pull request; this post covers the three
changes that alter day-to-day use, and leads with the auth one because
it needs an action before upgrading.
Two clips are recorded from a real session against a local-ai built
from master with the live gallery loaded: model-lifecycle.mp4 walks
the unified models and backends pages, import-model.mp4 shows the
rebuilt import form. Both follow the clip conventions in
.agents/preparing-a-release.md: h264, no audio track, 1000x562, under
30 seconds, and named after the feature so they stay reusable.

* docs(blog): anti-slop pass over the 4.9 post
Ran the post through the humanizer and no-ai-slop rules, calibrated
against what-landed-in-localai-4-8.md. That post is the one #11324
left unchanged, so it sets the rate for this series.
The draft ran denser than it on two constructions: "rather than" at
5.1 per thousand words against 3.5, and "instead of" at 3.1 against
1.6. Both are now at or below the 4.8 rate, 2.7 and 1.5, by rewriting
seven of them as plain statements.
Also cut: "keeping both cost a mode switch", a ledger metaphor for
something that is not money, which is the tell #11324 removed eight
times from the APEX post. "A follow-up fixed the thing that made that
awkward", an unearned framing plus a colon reveal. "This release adds
a different one: compress them", a second colon reveal. And
"byte-structurally identical", a second exactness idiom in a post that
already uses "byte-identical" where the precision carries weight.
Five paragraphs opened with "Two things" or "Two details", so three of
them start differently now. The summary listed three items, which is
the rule of three; it lists four, like the 4.8 summary.
Every figure, PR number, link and media reference is unchanged, checked
by diffing them out of both revisions. Hugo builds clean and the
rendered HTML has no em dashes.
