The AI-assistant policy says an AI agent must never add a Signed-off-by
trailer, because only a human can certify the DCO. That is right for the
case it was written for: an assistant helping a contributor who then
signs off themselves.
It does not fit automation a maintainer runs. Those pull requests have no
human submitter, so nothing ever signs and the DCO check blocks them
permanently. Sixty-one open pull requests from the maintenance bot are in
exactly that state, every one of them correctly following the documented
rule.
Carve out the case: automation a maintainer operates signs off with that
maintainer's identity. The maintainer certifies the DCO, as they do for a
commit they typed by hand, because they configured the automation, own
its output, and take responsibility on merge. The Assisted-by trailer
still records that a model wrote the code, so provenance is unchanged.
Keep the exception narrow. An assistant helping an outside contributor
still must not sign off, and a bot must not sign for anyone but its
operator, including on a contributor's branch it pushes to.

* fix(distributed): evict only when a node is known to be full
scheduleNewModel asked the registry for a free replica slot and treated
every error as "this node is full", so a control-plane database slow
enough to time out the lookup evicted a healthy loaded model. The
evicted process died, a peer frontend still holding its address dialled
the dead port and retried, and the model thrashed between nodes. The
comment on the branch already said it meant a full node; the code never
tested for it.
Evict only on ErrNoFreeSlot. Any other error now returns and names the
lookup that failed, so a slow database degrades into a diagnosable
load failure instead of into lost work.
An audit of the rest of the router found one branch of the same shape:
node selection discarded the error from its last-resort finder, so a
database timeout there also produced a nil node and evicted for it.
That path now returns unless the finder said gorm.ErrRecordNotFound,
which is the only answer that means the cluster had no node to give.
No other destructive branch in router.go fires on a generic error.

* fix(distributed): checkpoint heartbeat writes instead of writing every beat
Every heartbeat UPDATEd backend_nodes. Six nodes at a ten second beat is
roughly 52,000 writes a day against a six-row table, and that churn is
what turned a blocked autovacuum into a 460 MB table whose six-row scan
cost 867 ms and timed out the queries that place models.
A beat carrying only a fresher timestamp now waits for the checkpoint
interval. Each reported field is compared against the value last
persisted rather than tested for presence, because a worker sends its
disk figures on every beat and presence alone would suppress nothing.
A node's first beat, a changed total VRAM, total disk or GPU vendor,
and a free VRAM, RAM or disk reading that has moved more than 256 MiB
from the persisted value all still write at once. A node that is not
active is never suppressed, because it recovers only when the health
monitor sees a fresh timestamp.
The persisted column is up to one interval stale by design, so the
stale-node threshold moves from 60s to 5m to cover it.

* fix(distributed): fail worker readiness when a held backend is unreachable
The readiness gate tracked only the NATS link, so a worker whose backend
processes had died still answered /readyz with 200 and kept receiving
loads. One node did exactly that during an incident: it reported healthy
while its backend port refused connections, and every load routed to it
failed.
Readiness is now the NATS link and, for each backend process the worker
believes it is running, a short dial of its recorded address. A worker
holding no backends stays ready, because idle is a healthy state.
Signed-off-by: Ettore Di Giacinto <mudler@localai.io>
* fix(distributed): keep a starting backend out of the readiness dial set
A backend process is inserted into the supervisor map with its gRPC
address already recorded, but the address refuses connections until the
gRPC server binds, which the startup poll allows up to 30 seconds for and
which takes 10 to 15 seconds on a slow node. The new data-path readiness
probe dialled that address straight away, so a worker answered /readyz
with 503 for the whole of every cold backend start. The container
HEALTHCHECK absorbs that, but a Kubernetes readinessProbe at 10s does
not, and the worker would leave rotation each time it loaded a model.
The skip for a stopping process had no counterpart at the other end of
the lifecycle. Backend processes now carry a serving flag, set where the
startup health-check gate succeeds, and the probe dials only processes
that are serving and not yet stopping. backendStartStillValid becomes
markBackendServing: the check and the mark must share one lock hold, so
the flag can only ever land on the entry the key currently owns.

* feat(distributed): export control-plane database health gauges
Four transactions wedged on a corrupt index held the vacuum horizon open
for 42 days. Nothing measured it, so the first symptom anyone saw was
models failing to load six weeks later, by which time a six-row table
had grown to 460 MB.
Export the oldest xmin age, the longest open transaction, and the dead
tuple ratio on the registry tables. The first is the number that would
have caught it: it sits near zero in health and was 21,002,291.
Sampling is scrape-driven behind a cache, and a failed sample reports
the last good values rather than failing the scrape, because these
gauges matter most when the database is already struggling.
Signed-off-by: Ettore Di Giacinto <mudler@localai.io>
* fix(distributed): rate-limit failed control-plane database samples
The cache advanced its clock only on a successful sample, so once the
database started failing every scrape retried the query immediately.
That turned the cache off in the one regime it exists for: a retry
storm at scrape cadence aimed at a database already in trouble. A
catalog read that consistently exceeds the 5 second timeout also paid
that cost on every scrape, with all scrapes serialised behind the
sampler mutex.
Time every attempt rather than every success, so failures and timeouts
cost the same interval as good samples. Whether a good sample exists
moves to its own field, keeping the gauges absent until the first
success and holding the last good values through later failures.
Also note in the runbook that pg_stat_activity cannot see prepared
transactions or replication slot xmins, so a healthy-looking xmin age
does not by itself rule out a blocked horizon.
Signed-off-by: Ettore Di Giacinto <mudler@localai.io>
* test(distributed): pin that a failing database evicts nothing
Exercises the real distributed stack against a control-plane database that
refuses the router's slot lookup, and asserts the scheduler reports the
lookup it could not answer instead of falling through to eviction.
The failure is injected with privileges rather than a statement timeout. A
timeout set with ALTER DATABASE also breaks AutoMigrate, and it leaks into
every later spec in the suite unless it is reset, so the spec would end up
testing the migration rather than the scheduler. Instead the spec creates a
dedicated login role, points a second gorm handle at it, and revokes that
role's SELECT on node_models.replica_index. This has to be a separate role:
the test container's owner is a PostgreSQL superuser, and superusers bypass
every privilege check, so revoking from CURRENT_USER is recorded and then
ignored.
The revoke is scoped to one column on purpose. Revoking the whole table
would also blind node selection, which runs first and has a guard of its
own, so the scheduler would never reach the slot lookup this spec is about.
Leaving every other column readable lets selection succeed and lands the
refusal exactly on NextFreeReplicaIndex, which plucks replica_index. The
grant is restored from BeforeEach via DeferCleanup, so a failing assertion
or a panic cannot hand the next spec a role that cannot read.
Reverting the eviction guard fails this spec, which is the point of it: the
router then reports "no replica slot on keeper and eviction failed" for an
error that was never evidence the node was full. The surviving-row
assertions are secondary under this injection, because the eviction path
reads whole node_models rows and the same revoke blinds it too; a comment
in the spec says so, so nobody mistakes them for the load-bearing ones.
Also documents why the vector store and the control plane must not share a
database: the removable-tuple cutoff is per database, not per table, so one
transaction left open anywhere stops autovacuum reclaiming the node
registry, and a six-row table bloats into hundreds of megabytes. The note
names LOCALAI_AUTH_DATABASE_URL and LOCALAI_AGENT_POOL_DATABASE_URL as the
two knobs that must differ, and the localai_control_plane_oldest_xmin_age
gauge as the way to see it coming.
grep for StaleNodeThreshold and HealthCheckInterval in

* fix(distributed): close the review gaps in the heartbeat and health path
The stale-node threshold moved from 60 seconds to 5 minutes in this branch
because checkpointing makes last_heartbeat up to one checkpoint interval
behind by design. Two things were left inconsistent with that. NewHealthMonitor
still fell back to a hardcoded 60 seconds when handed a zero threshold, so any
future caller that stopped passing the configured value would mark every
healthy, beating node offline on every cycle. And the threshold itself had a
flag-name constant but no AppOption, no CLI field and no env binding, so an
operator who widened --node-heartbeat-checkpoint had no way to widen the
threshold to match. The fallback now tracks config.DefaultStaleNodeThreshold,
and --stale-node-threshold / LOCALAI_STALE_NODE_THRESHOLD is wired the same
way its sibling is.
Heartbeat suppression compared the RAW reported free VRAM against the
snapshot, but the column persists capAvailable(raw, ceiling). On any node with
a VRAM budget set, whose actual free VRAM oscillates above that ceiling, every
beat looked material while the persisted value never moved: suppression was
defeated on exactly the nodes an operator had configured, and the write
amplification this branch exists to remove came straight back there. The
comparison and the snapshot now both hold the capped figure, so they measure
the same quantity as the column.
Fixing that needs the ceiling, and reading it cost a SELECT on every beat,
including suppressed ones. The skip decision therefore moved ahead of the
updates map and now reuses the ceiling cached on the last durable write, while
the write path still re-reads it before capping anything. A ceiling that
changed inside the checkpoint window can cost one extra or one late write; it
cannot persist a wrong figure. A suppressed beat now costs no query at all.
Also: the operations section now says to grant pg_read_all_stats to the
LocalAI role, because PostgreSQL blanks backend_xmin and xact_start for
sessions owned by other roles, and the transaction that wedged the horizon in
the incident was a co-located vector store connecting as a different role, so
without the grant the new gauge sees only our own sessions. The compose
healthcheck comment now describes readiness covering the backend data path,
and the control-plane gauge registration records the otel.SetMeterProvider
ordering it depends on.

* fix(distributed): resolve the gauge's table names through gorm
The dead-tuple gauge queried pg_stat_user_tables against a hardcoded list
of three table names. Those three do not agree on where their name comes
from: BackendNode and NodeModel take gorm's default pluralisation, while
GalleryOperationRecord overrides TableName, and gallery_operations
already had a constant of its own that the list duplicated.
A literal list keeps compiling after any of that moves, and the query
then matches nothing. The failure is silent and it points the wrong way:
a dead-tuple ratio that matched no rows reports the same numbers as a
cluster with no bloat, so the gauge would look healthiest exactly when it
had stopped working.
Ask gorm what each model is stored as instead, which follows a TableName
override and the default pluralisation alike. A spec pins that the
override really is consulted: naive pluralisation of the type would give
gallery_operation_records, so the resolution cannot quietly stop asking
the model.

Fixes#11673: on macOS the DMG launcher appeared to launch nothing. After
installing, the app sat in the menu bar with no window, nothing listening

- Start the LocalAI server automatically when the launcher opens and right
after a fresh install. The new auto_start_server config key defaults to
enabled and gets a settings checkbox; the legacy auto_start key was never
honored nor exposed, so every existing launcher.json carries an
unintentional false and is deliberately left behind.

Node placement and replica rules could only name a model, so an operator
who pinned "llama3" to the GPU tier had to rewrite the rule whenever a
different model took over that job. An alias already gives a stable name
for whichever model serves it, and a rule on that name makes it a
deployment slot: repoint the alias and the placement follows.
A rule keeps the name the operator chose. Reads resolve that name through
the config loader to the model the rule governs, so the reconciler counts,
schedules and trims replicas of the target, and the router finds an
alias-keyed rule from the target it is already routing. An alias that
resolves to nothing governs nothing loadable, so the reconciler skips it
and the write paths refuse it.
A replica is shared by every name that resolves to it, so only one rule
can decide where it runs. The REST and MCP write paths reject a rule whose
target another rule already governs. A pair that arrives some other way,
such as a seed file or an alias repointed onto a model that already has a
rule, resolves in favour of the rule named after the model itself and then
the oldest, and the rest are listed as shadowed.
The eviction guard is the exception: it matches rules to replicas in raw
SQL inside a locking transaction and cannot resolve an alias. It reads a
stored target that the reconciler refreshes each tick, and falls back to
the rule's own name when that target is empty.

The scheduling page kept a node-label browser open above the rules

The browser is gone. The selector's key input now completes against the

* fix(distributed): size model fit against the cluster, not the frontend
The models page asked the frontend how much memory a model may occupy.
In distributed mode the frontend is usually a GPU-less pod while every
model runs on a worker, so a fleet of GPU nodes was told it could only
run the smallest CPU build. The variant picker's fits flag and its
auto-selection came from the same place, as did the hardware
recommendations.
The registry now reports the largest single healthy backend node. The
largest node, not the fleet total: a model loads into one node, so four
16GB workers are not a home for a 40GB model. An operator-set VRAM
budget caps a node's contribution, because the scheduler refuses a load
above that ceiling anyway, and a GPU node beats a CPU node holding more
system RAM.
GET /api/resources and GET /api/models carry this as an additional
cluster object. Their aggregate and ram fields keep reporting the
frontend's own hardware, which is what the resource monitor shows.
Variant selection judges backends against the union of the capabilities
present in the cluster, the way backend discovery already did.
Every path degrades to the local host: no cluster object in single-node
mode, and none when the registry cannot be read, so a hiccup narrows the
answer back to single-node behaviour rather than marking the whole
catalog too large.
The verdicts now name the node they belong to, since a model fits
somewhere or nowhere.

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.

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.

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.

* test: drop the static network lint in favour of real isolation
The offline test suite already prevents tests from reaching the network
twice over: run-test-linux-offline.sh puts the test process in a cgroup
and REJECTs egress outside the private ranges, and HardenedTransport
installs testnetwork.LocalGuard to refuse dials that resolve to a public
address. Both fail the test with a precise error at the moment of the
dial.
test-network-lint.sh added neither. Its diff stage defaulted to a HEAD
base, so on a clean checkout it compared the tree against itself and
inspected nothing; the branch's own commits were never examined. It only
produced output when an earlier job step dirtied the tree, and then it
matched a bare https?:// against whatever changed. make react-ui runs
npm install rather than npm ci, so CI rewrote
core/http/react-ui/package-lock.json and the lint reported an npm
registry URL as forbidden test network access:
+ "resolved": "https://registry.npmjs.org/hono/-/hono-4.12.25.tgz",
Its fingerprint stage was self-defeating in a quieter way: hashing the
whole tree's network-mechanism inventory meant every rebase onto a master
that touched any _test.go needed a manual baseline bump, so the check
mostly caught its own staleness.
Remove the script, its make target and the two prerequisite edges, along
with the test-network: fixture markers that existed only to suppress it.
The isolation itself is untouched.

`test-coverage` prerequisite lists into a recipe line, so parallel make could
not fingerprint the tree while generated fixtures were still changing. That

* feat(router): make KNN a first-class classifier with a persisted, curated corpus
Add `classifier: knn` — similarity-weighted voting over labelled
example prompts. Unlike score/colbert it needs no classifier model:
label knowledge lives in a corpus seeded and curated through the
admin API, so routing decisions are deterministic, auditable, and
grounded in graded experience rather than a model's opinion.
Epistemic gate: corpus entries below knn.similarity_threshold cannot
vote; when none clears it the classifier activates no labels and the
router uses the fallback — a prompt unlike all labelled experience is
treated as undecidable, not guessed. Decisions record
nearest_similarity (also on fallback rows) so admins can see how far
the nearest labelled experience was; the Routing tab explains
out-of-corpus fallbacks and shows per-label corpus counts.
Persistence: one JSONL file per router under
<data path>/router-corpus (text, labels, vector, embedder
fingerprint). The file is the source of truth; the local-store index
is rebuilt from it at classifier build time and stays a pure
in-memory index. Entries recorded under a different embedding model
re-embed on load. Also corrects the docs' false claim that
local-store collections persist — the embedding cache never survived
restarts (and still doesn't); the corpus does.
Corpus input is API-only by design (entries may contain example user
content): POST /api/router/{name}/corpus seeds (labels validated
against declared policies, embedded server-side, indexed
immediately), GET .../corpus/stats inspects — label counts only,
entry texts are never returned by any surface — DELETE .../corpus
wipes. Admin-gated like the sibling router endpoints, and exposed as
MCP tools (seed_router_corpus / get_router_corpus_stats /
clear_router_corpus) in both the httpapi and inproc clients with
coverage-test route mappings.
Plumbing: VectorStore gains SearchK (top-K was hardcoded to 1);
local-store gets InsertBatch/Delete as optional fast paths;
RouterConfig gains a knn block (embedding_model, k,
similarity_threshold, vote_threshold, store_name) with meta-registry
fields; the classifier dropdown now offers knn and the
previously-missing colbert; embedding_cache is ignored (with a
warning) for knn — it IS an embedding-KNN lookup; the stale
/api/instructions intelligent-routing entry is rewritten (it
described a classifier that no longer exists); swagger regenerated.
Tests: KNN vote/gate specs with hand-computed vote shares, corpus
manager suite (restart reload without re-embedding, fingerprint
re-embed, dedupe, hostile store names), middleware specs (corpus
routing, gate fallback, config validation, cache-wrap refusal),
corpus endpoint specs pinning the texts-never-returned contract, MCP
catalog + route-mapping gates, and a Playwright spec for corpus
stats and the out-of-corpus decision detail.

* feat(router): name consulted corpus neighbours in knn decisions
Every knn decision (decision log rows and the /api/router/decide
response) now carries neighbors: the K retrieved corpus entries by
descending similarity - including ones below the epistemic gate, which
is what makes fallback decisions diagnosable - each as {id, similarity,
labels}. The id is the entry's content hash (first 8 bytes of the
SHA-256 of its text, hex): stable across reseeds and re-embeds, and
text-free, so an external platform that seeded the corpus can recompute
text->id on its own copy and bucket decisions by corpus region (per-
region reliability accounting) without corpus text ever leaving the
server. A corrupt index payload surfaces as an id-less neighbour at a
real similarity instead of disappearing.

* refactor(router): deduplicate knn plumbing and cut corpus hot-path waste
Post-review cleanup of the knn-first-class-router branch; no behaviour
changes on the API surface.
Reuse/altitude:
- RouterKNNConfig.ResolvedStoreName is now the single source of the
router-corpus-<name> default (was hand-derived in four files).
- corpus.ResolveKNNRouter + corpus.Seed carry the shared model
resolution and seed validation; the REST endpoints and the assistant
MCP client are thin transport adapters over them, with sentinel
errors mapped to HTTP statuses at the echo boundary.
- middleware.NewClassifierDeps assembles the classifier dependency set
once for all five entry points (OpenAI, Anthropic, realtime, decide,
corpus) instead of five hand-copied literals.
- router.AllClassifiers feeds both the status endpoint and the
unknown-classifier error, ending the classifier-list drift.
- Per-classifier requirements moved out of validateRouterPolicies into
their buildClassifier arms; the knn arm owns its embedding_cache
opt-out instead of a name-check in the shared wrap tail.
- adminOnly replaces four inline copies of the admin gate in the
middleware routes.
- localVectorStore.Search delegates to SearchK (identical traces).
Efficiency:
- Manager.Add embeds outside the manager mutex and appends to the
JSONL file (O(new) instead of O(corpus) rewrite); a torn tail from a
crash mid-append is tolerated on read and repaired on next write.
- Stats memoises per store keyed on the file's stat fingerprint and no
longer takes the manager mutex, so the 5s status poll stops parsing
vector-laden JSONL and stops blocking behind seeds.
- KNN Classify decodes each neighbour payload once (was twice) and
builds refs and votes in a single pass with one fallback return.
- Corpus file writes fsync before rename/close.
- The corpus manager is built eagerly in newApplication (sync.Once
dropped); test helper dead branch removed.
