Ettore Di Giacinto e25293f7bc feat(cluster): make a peer prove which replica it is
GET /api/cluster/peer authenticated with the deployment's shared
registration token and took the dialling replica's id from ?id= on trust.
Every worker holds that token, so anything holding it could open a peer
link as any replica: relay through it to every worker tunnel that replica
owns, displace a real replica's inbound link by declaring its id, and
point the roughly 31 GiB per-session receive window at one replica.

Validating the id against the instances table does not fix this, because
the attack declares a real replica's id. So the route now checks two
credentials and needs both. The shared token still says the dialler
belongs to this deployment; a new per-replica credential says which
replica it is.

The credential follows the per-node worker credential rather than
inventing a second mechanism: crypto/rand.Text, stored only as a hex
SHA-256, compared in constant time, with no fallback to the shared token.
It differs in the stronger direction. A worker's credential is minted by
the frontend and handed over once; a replica writes its own instances
row, so it mints its own secret, publishes only the hash in the same
statement that publishes its address, and never sends the plaintext
anywhere but the peer dial.

A peer that presents no credential is refused, not waved through. An old
replica and an attacker holding the shared token send the same request,
so accepting the first accepts the second; there is no safe downgrade
here, only a quiet one. The refusal is made loud instead, on both sides,
naming the upgrade rather than the network. On the documented
frontend-first order a new replica still dials an old one; an old replica
cannot dial a new one, which costs relayed requests that land on a
not-yet-restarted replica and surfaces as no route, never as absence.

A rejected peer gets its own sentinel, ErrPeerRejected, whose unwrap
chain carries ErrPeerUnreachable as well and no absence sentinel at all.
Keeping the older sentinel means no existing consumer changes behaviour;
the cause stays out of the chain, so absence cannot escape through it and
nothing can read an authorization failure as a worker that went away.

One consequence beyond the fix: a replica with no advertised address has
no instances row, so it now cannot dial out either. It was already
unreachable inward. The startup error and the docs say so.

Registry.Register, NewMembership, NewPeerPool, PeerHandler and
RegisterClusterRoutes all gained required arguments, so the identity
cannot be dropped without a compile failure.

Ettore Di Giacinto 016686a3db chore(distributed): take the nats-io modules out of the build
Distributed mode has not dialled a message broker since the control plane
moved onto the workers' own outward tunnels and every fan-out family moved
onto PostgreSQL LISTEN/NOTIFY. What was left was the dependency itself, and
the code that existed only to feed it.

Dropped from go.mod: nats-io/jwt/v2, nats-io/nats.go, nats-io/nkeys,
nats-io/nuid and testcontainers-go/modules/nats, along with the fourteen
indirect requires that only the NATS testcontainer pulled in. go.sum carries
no nats line either, so the removal is not the partial kind where the require
goes and the checksum stays.

Deleted with them: pkg/natsauth in full, the broker client's remaining
options and TLS files, the per-node JWT minting on both the register and the
approve path, and the natsauth.Config parameter threaded through the node
routes. The credential manager is renamed and stripped rather than deleted,
because it still holds the tunnel token that every re-registration rotates.

The bus flags stay accepted and ignored, and are now hidden, on every command
that had them, so an existing unit file, compose file or Helm values file
still starts on the day of the upgrade. What is not kept is the validation
that REQUIRED one: a distributed frontend started with no bus URL is no
longer fatal. The TLS paths lose type:"existingfile" deliberately, so a
certificate deleted along with the broker cannot fail a startup.

One operator-visible behaviour change: --nats-require-auth no longer makes an
agent worker wait through admin approval. Ask for that wait with
--distributed-require-auth, which already implied it. It is documented in the
migration section and pinned from both sides.

A deployment now needs PostgreSQL and the frontends' own HTTP listener, and
nothing else.

coverage-baseline.txt moves from 54.2 to 62.0.

Ettore Di Giacinto be14db21e2 feat(distributed): move the last nine fan-out families onto PostgreSQL
Gallery progress and cancel, the operation cache's start and end, the model
and backend cache invalidations, staging progress, and the prefix cache's
observations and invalidations now travel on the LISTEN/NOTIFY carrier. No
subject is published or subscribed on messaging.Client anywhere in the tree,
which is what makes retiring that package a deletion rather than a migration:

  $ grep -rn 'natsClient\.Publish\|nats\.Publish\|\.Nats\.Publish\|QueueSubscribe\|SubscribeReply\|\.Request(' \
      --include='*.go' core/ pkg/ | grep -v _test \
    | grep -v 'c\.Request()\|ctx\.Request()\|Request()\.Context' \
    | grep -v 'core/services/testutil/fakebus.go'
  core/services/messaging/client.go:168,170,172,227,234,236,250,252,254,268,269,287
  core/services/messaging/interfaces.go:21,22,23

Every remaining hit is inside core/services/messaging itself. The production
reads of the NATS client are now three, all of them the documented agent-worker
exception: Close on shutdown, the agent pool's publisher, and the agent-cancel
carrier passed to newFanoutBridges.

Prefix-cache observations publish like every other family rather than through a
method that refuses a message too large for a notification. The plan proposed
such a refusal on the reasoning that a long prompt makes a chain of thousands of
entries; ExtractChain caps a chain at Config.MaxDepth blocks, MaxDepth is a
constant with no operator knob, and the chain reaching Sync.Observe has one
source, the router's own extraction hook. A worst-case observation is a few
kilobytes against an 8000-byte cap, so the hot-path spill the refusal was
designed to avoid cannot occur, and shipping it would have added the programme's
only deliberate message drop to guard a condition that cannot arise. pgbus gains
FitsInline instead, a predicate that shares one size decision with Publish and
decides nothing, and core/application refuses at startup to wire a prefix cache
whose configured depth would put every observation over the cap.

The carrier choice is no longer stated at four sites. StagingTracker.SetPublisher
and SubscribeBroadcasts become one SetBroadcaster, so a tracker that publishes
where its peers are not listening cannot be spelled; prefixcache.Sync gains
SubscribeBroadcasts, which reads the carrier it publishes on; and the gallery
service and the operation cache are wired by methods on DistributedServices that
name no carrier at all, so the NATS client beside it cannot be handed over.
OpCache.SetMessagingClient and GalleryService.SetNATSClient are renamed to
SetBroadcaster so a missed call site fails to compile.

Two pre-existing defects that the two-real-carrier specs surfaced are fixed. A
progress tick published before a cancel and delivered after it cleared Cancelled
and left the operation reading as still running on that replica; mergeStatus now
drops a stale tick rather than merging it. GetStatus and GetAllStatus handed out
the stored OpStatus pointer while the broadcast subscribers mutated it in place,
so an /api/operations response could be marshalled mid-write; both now copy.

Ettore Di Giacinto 94bfbd2221 feat(distributed): carry the state.*.delta families on PostgreSQL
syncstate.Config held one carrier field typed as the NATS client, so a
pgbus.Bus could not be handed to a SyncedMap at all: it satisfies
messaging.Broadcaster and not MessagingClient. The durable re-hydration
path built for the responses map therefore had a NATS-only consumer and
nothing in the build said so.

The field becomes Bus messaging.Broadcaster, SubscribeJSON moves to its
own file and relaxes its parameter to Broadcaster, and the four adopters
fan out over PostgreSQL LISTEN/NOTIFY: fine-tune jobs, quantization jobs,
agent tasks with their per-tenant children, and Open Responses metadata.
A new spec proves it on a real database, over two Bus instances on two
pinned listener connections: a Set and a Delete carry, a payload past the
8000-byte notification cap comes back byte identical through the spill
row, two families sharing one LISTEN channel stay separate, and a
terminated listener re-hydrates a row written while it was gone.

The five sites that each chose a carrier for an adopter are collapsed
into one DistributedServices.Broadcast() accessor. Five field reads were
five chances to leave one family on NATS with nothing failing, because
messaging.Client satisfies Broadcaster too. The accessor also refuses to
hand out a nil pgbus.Bus wrapped in a non-nil interface, which every
adopter would read as "broadcast" and dereference on the first Set.
SetTaskSyncNATS and SetJobSyncNATS are renamed to SetTaskSyncBus and
SetJobSyncBus so a missed wiring site fails to compile.

The response metadata table gains a retention of its own, defaulting to
24 hours. It inherited the Open Responses store TTL, which defaults to 0
meaning no expiration. Zero is defensible for a map that dies with the
process and is not for a table: the table grew for the life of the
deployment and a restarting replica re-hydrated every response the
cluster had ever created. A row that names its own expiry is still judged
on that column alone, and "this row is dead" now has one SQL spelling
that PurgeExpired deletes by and ListUnexpired is the negation of, so a
hydrate cannot resurrect what a sweep has already retired.

Ettore Di Giacinto e29a4e5d15 feat(cluster): reach every worker through its tunnel, never its address
The tunnel, the fence, the registry and the relay were all built and none of
them carried a byte: every dial from the frontend still went to the address a
worker registered. This is where that stops. One WorkerDialer resolves where a
worker's tunnel is held, opens a stream on it locally or relays through the
owning replica, and hands back a conn past both handshakes; gRPC, the file
stager's HTTP client and the log-streaming WebSocket are all pointed at it.

A worker's address stops being somewhere to connect to and becomes the name of
which backend process a stream is for. It still appears in URLs, logs and
errors, because that is what identifies the process; what it no longer decides
is where the bytes go.

Nothing falls back to dialling it. BackendClientFactory now has exactly one
method, NewClientForNode, and returns an error where there is no way to reach
the worker. The direct-dial constructor was removed rather than kept beside it,
because leaving one on the interface keeps the bypass one word away from every
call site that holds an address, which is all of them.

The second construction path is closed too. DistributedModelStore built remote
models with a nil client, and pkg/model.Model.GRPC then dialled the raw address
lazily on first use - reached in production by ShutdownModel's Free and by the
backend monitor's Status. Those models now carry the tunnel-backed client, and
a model that cannot be given one is logged and not listed.

Four conditions stay unmixable, and one path produces absence: the dialer
answers ErrNoConnection only where Owner's liveness join did. A peer that will
not answer, a stale ownership row, a worker's own refusal and a missing relay
path are each reported as themselves. This matters because nodes ACTS on
absence, and the collapse would have it reclaim the models of a worker that is
connected and busy.

That is not hypothetical. Writing the mutation for it exposed the bug in this
change's own first draft: probeHealth returned bare false when it could not
build a client, and tryWarmPath deletes the replica row on a false probe. A
frontend whose dialer broke would have emptied node_models for the whole
deployment while every model kept running. probeHealth now returns alive and
probed separately, the reconciler gets a ProbeUnknown outcome that neither
advances nor clears a failure streak, and the health monitor skips rather than
counting a miss.

Task 5 left the relay's open timeout at a fixed 15s and said so: no operator
has the information to set it, because the number that matters is the original
client's remaining budget, which is invisible on the relay side. The dialer has
that budget, so it now states it in the relay request frame and the owner takes
the smaller of the two. It can only shorten - a patient client must not be able
to park a relay goroutine and a stream slot on a worker that stopped accepting.
Zero is written as no budget at all, since on the far side the number zero is a
caller with nothing left and would refuse healthy traffic.

Seven mutations, each reddening a named spec: peer-unreachable as absence; the
local-failure guard dropped; max instead of min on the budget; the nil-client
model restored; ProbeUnknown falling through to the reaper; OwnerRow instead of
Owner; probed collapsed into alive. The first budget spec passed for the wrong
reason - a handshake deadline, not the relay - and was replaced by three that
each assert one link, including one where the spec plays the owning replica and
reads the budget out of the frame instead of inferring it from a clock.

Ettore Di Giacinto 60c2a47737 fix(worker): spec the tunnel's routing table, which was the SSRF boundary
Review follow-up. One blocking finding and seven others.

The blocking one first, and it is this project's recurring shape: the untested
path. loopbackService is the function whose comment calls the discarded host
"the security property this function exists for", and nothing tested it. The
reviewer replaced its body with a dial of whatever the frontend named, no port
range, and all 131 specs passed. Every spec installed the permissive test
dialler, so the real routing table was exercised nowhere.

It now has specs, and the property is stated as reachability rather than as a
property of the code: a listener on 127.0.0.2 that only the frontend's target
names must NOT be reached. Plus the port-range table, fixedService, loopbackAddr,
tunnelEndpoint, and the table itself, which moved out of Run into tunnelServices
so it can be built without starting a worker. One spec drives a real stream
through that table over the wire, so the routing rules are exercised end to end
at least once rather than only in isolation. The reviewer's mutation now reddens
ten specs, and six narrower ones redden between two and four each, so no spec is
riding on another.

The shape changed too, not only the coverage. The dial address is built from a
loopbackHost constant and strconv.Itoa of a validated int, so nothing derived
from the wire reaches DialContext at all: restoring the hole takes ADDING a data
flow, not deleting a check.

And a taxonomy fix found while specifying it. A port outside this worker's
allocator range was reported as unavailable, which tells a frontend to retry
something that can never work. It is a bad request now, and a backend that is
merely not listening yet stays unavailable, which is the retryable one.

Agent nodes no longer get a tunnel credential. Nothing dials into an agent
worker, so a tunnel replaces nothing for it and no client would open one, and
the gate is at the mint site rather than in the handler: with no credential
minted the hash stays empty and the existing empty-hash refusal covers it, so
enforcement is structural.

Two comments and one doc paragraph said an anonymous registrant gets a "working"
credential. With auto-approve off the node is pending and the credential is
inert, which is the distinction this same change argues three files away to
justify minting for pending nodes at all.

A refusal reason over the frame limit was cut on a byte boundary and could split
a rune. It cuts on a rune boundary now, and the code survives truncation, which
is what keeps a refusal classifiable.

Also: the pending-node spec asserted only that a credential was non-empty, so a
credential derived from the shared token passed it; it now pins per-node-ness the
way the headline spec does. The tunnel handler's citations into nodes.go were
stale before this branch landed, having been written against a file the same
commit was editing, and are by function name now. The static-NATS path says
plainly that an externally forced rotation locks it out until restart, and where
that gets fixed. tunnelproto gained direct specs, including that a read failure
is never reported as a refusal.

Ettore Di Giacinto 6a08380611 feat(worker): dial, hold and serve the tunnel, on a credential of its own
The worker end of the tunnel. It dials wss://<register-to>/api/cluster/connect,
holds one yamux session as the CLIENT, and serves every stream the frontend
opens on it. Nothing dials into the worker, which is the point: no inbound port,
no reachable address.

Each stream opens with a length-prefixed frame naming a tag and a target, and
the worker answers before either side speaks the tunnelled protocol. The reply
is sent on every stream, not only on refusal, because the protocols carried here
are client-speaks-first and a reply sent only sometimes would arrive interleaved
with a response body. Two tags today: grpc reaches a backend process, and only
on 127.0.0.1 within this worker's own backend port range, because a tunnel
terminates inside the worker and letting the frontend name a host would make
every worker a proxy into its own LAN; http reaches the worker's file-transfer
server, whose address the frontend is not asked about.

An unknown tag, an unreachable local service and an unparseable request are
three refusals and stay three on the wire. A frontend gives up on the first and
retries the second. Each is answered AND the stream is ended: a worker that says
why and leaves the stream open has parked the caller on a request nobody will
answer, and a deadline on the far side cannot tell that from a slow worker. The
specs assert the stream ends rather than that an error occurred, which is what
phase 1 shipped in three places and held in none.

Reconnects double from 500ms to a 30s ceiling, each wait drawn between half the
interval and all of it, and the interval returns to its floor only after a
session that LASTED. Resetting on connect is how a rolling restart, where every
dial succeeds and dies moments later, becomes a retry storm against the first
replica back up. Nothing is assumed to survive a reconnect: the credential is
read at dial time, never captured.

And the credential is now real. The tunnel endpoint advertised authenticating a
worker against its own secret, but registration stored the hash of the shared
registration token, so a leak plus a known node ID still opened a tunnel.
Registration now mints a per-node secret, returns the plaintext once as
tunnel_token, and stores only its SHA-256 in a new column; the endpoint compares
against that and does not fall back to the old one. Rotating on every
registration follows from storing only the hash, since a re-registering worker
cannot be told the secret it already holds; its live tunnel is unaffected,
because the credential is checked when a tunnel is dialled and never again.

Unlike the agent API key and the NATS JWT next to it, the credential IS issued
to a node awaiting approval: the tunnel route re-reads the node's status on
every dial and refuses a pending one, so it is inert until an admin acts, and
withholding it would strand every worker that registers exactly once.

A node that has not registered since this change cannot tunnel, and the column
cannot be back-filled because the plaintext only ever existed in the response
that minted it. The boot warning that said tunnels need LOCALAI_REGISTRATION_TOKEN
is replaced: it was true while the tunnel authenticated against that token's
hash, and says the wrong thing now. What is still true, and is what it warns
about instead, is that without one, registration itself is unauthenticated.

Ettore Di Giacinto b2be4177f2 fix(cluster): harden the worker tunnel, and stop starting a database per spec
Review follow-up. Twelve findings, none blocking, grouped here by what they
protect.

Panics. The handler now recovers between the WebSocket upgrade and the
hand-off, the way the peer link next door already did: net/http recovers the
panic but leaves the hijacked socket open, so without this a worker keeps a
session this replica has no entry for and will never detach. The claim gate in
Attach and reclaimOne is now released with defer, so a panic under Claim cannot
wedge one node's gate for the life of the process. SetTunnels gained the
nil-receiver guard its sibling Stop has.

Operability. A deployment with no registration token stores an empty token_hash
on every worker, so every tunnel dial 401s forever on a frontend that looks
correctly configured. That now warns at startup, logs its own line rather than
sharing the "wrong token" one, and is stated in the docs together with the fact
that setting the token later needs the workers to register again.

Authorization. A node still awaiting admin approval is refused with 403. The
rest of /api/node/ gates on nothing, but the two places that hand a node
something durable, its API key and its NATS credential, both refuse a pending
one, and a tunnel is that kind of grant. Draining and unhealthy nodes keep
their tunnels on purpose.

Comments that claimed more than the code. The global auth middleware does run
on this path and then declines to reject; the future per-node secret only lands
without a change here if it lands in TokenHash; the empty-hash guard is
defensive rather than deciding; ClusterPathPrefix is no longer only
replica-to-replica; the docs no longer say a reaped replica re-claims
unconditionally.

And the test harness. SetupTestDB started a PostgreSQL container per BeforeEach
with a readiness deadline it asserted on, which is one chance per spec to fail
one spec inside its setup, anywhere, never twice in the same place: the shape of
the flake seen twice here and never reproduced. It now starts one container per
process and creates a database per call, which is the pattern tests/e2e already
proved. Isolation is unchanged and is now asserted for the first time. All 69
call sites are untouched; the eleven consumer packages run 1404 specs green, and
jobs went from 34.3s to 3.3s, agents from 13.8s to 1.9s, cluster from 97.4s to
37.5s.

Ettore Di Giacinto 629381f3d2 feat(cluster): open the door a worker dials its tunnel through
A worker needs no inbound port: it dials GET /api/cluster/connect, the
connection becomes one multiplexed yamux session, and the frontend opens a
stream on it per request. This adds the endpoint that accepts that dial and
attaches it to the tunnel registry.

The dial is authenticated against the NODE's own stored token hash rather than
the deployment's registration token. That is the mechanism, not yet the
isolation, since a worker still registers by presenting the shared token; what
it rules out is the shortcut of comparing against the configured value, which
would have to be unpicked the day workers get their own secrets.

Every refusal happens BEFORE the WebSocket upgrade, so a dialer reads an HTTP
status rather than a handshake error. The route is registered in every
deployment, single-binary ones included, which is what puts it in front of the
route-coverage test that holds that rule in place; with no node registry it
refuses every dial, and tells a credentialed one the frontend has no cluster
rather than that its token is wrong.

A lookup that FAILED is answered as a failure. Reporting a database that could
not be read as "unauthorized" would send a worker re-registering, throwing away
the identity its tunnel and loaded models are keyed by.

Wires the tunnel registry in core/application/distributed.go and hands it to
the membership loop. Without that call the re-claim after a replica is reaped
had no production caller and could never run.

Ettore Di Giacinto d576af6943 fix(cluster): hold the guarantees phase 1's comments were claiming
Review found the recurring class: assertions that a wrong implementation
also satisfies.

The "refuse promptly, never park the peer" guarantee was stated in three
places and tested in none. Removing the Close from the no-relay branch left
the whole cluster suite green, because the specs asserted only that some
error arrived and yamux reports a read deadline as ErrTimeout: a parked
stream satisfied that as well as a refused one. Both specs now require an
ENDING, EOF or a reset, inside a deadline short enough that parking is
unmistakable, and both go red when the Close is removed.

Deregistration existed only in a comment. Membership.Stop ended the loop and
left the row behind, so every clean rolling restart had peers dialling a
corpse for the full liveness window; the shutdown comment described the
opposite. Registry.Deregister deletes the row and the connections that
replica owned, in one transaction, for the reason the sweeper does both, and
an e2e spec pins departure inside a budget shorter than the liveness window
so it cannot pass on the sweeper doing the work. Before: the spec times out
with both replicas still live. After: 3.6s.

The configured advertised address bypassed every check discovery makes, so
the one value most likely to be copied between hosts, 127.0.0.1, was taken
verbatim and would make every peer dial itself. Both paths now share one
rejection rule: unparseable is refused, "this host" is warned about once and
honoured, because a single-host deployment uses it correctly.

Two comments claimed more than the code does. The sweeper said a stalled
replica recovers via re-register; only its instance row does, while the
connections another replica reaped stay gone and the sockets stay held here
- phase 2 must re-claim, on re-register, every connection a replica still
holds locally. And Owner became OwnerRow, documenting that the owner it
names may be dead for up to InstanceLiveness plus a heartbeat and that any
caller acting on it must join instances itself, so the deferred constraint
lives at the call site rather than in a report; the plain name is left free
for the joining version.

Minors: warn once when the peer link mounts with no registration token, so
an operator sees the cause rather than 401s; Stop no longer blocks forever
when Start was never called; corrected the NewRegistry migration doc and an
e2e comment that described a 6s window as "throughout".

Ettore Di Giacinto 3b19575f81 feat(cluster): give phase 1 a call site, and prove it against real replicas
Tasks 1 to 5 built an instances table, a splice, both halves of a peer link
and an epoch fence, and nothing in the tree called any of it: no replica
registered, no route was mounted, no sweeper ran. Proving phase 1 end to
end therefore had to start by wiring it.

A frontend in distributed mode now publishes the address its peers dial,
heartbeats it, and sweeps replicas that stopped answering along with the
connection rows they owned, in one pass so the two can never disagree about
who is alive. It serves the peer link and owns the sessions peers dial in,
refusing streams on them until phase 2 installs a relay: a session nobody
accepts on does not fail a peer's Open, it hangs it.

The address is the one peers use, not the one the process binds, and it is
derived from the route to PostgreSQL. That derivation only holds while the
database is remote, so LOCALAI_DISTRIBUTED_ADVERTISE_ADDR sets it
explicitly and a replica that can determine neither warns and keeps
serving rather than failing to start.

Three e2e scenarios run against real local-ai processes, real PostgreSQL
and real dials: replicas publish addresses that can actually be connected
to; a sibling opens a stream over the peer link and is refused without the
cluster token; and a killed replica is reported unreachable, never absent,
loses the claim it held, and takes no worker with it. Each was verified by
mutation: eight injected defects, each failing the scenario that claims to
catch it.

Also moves RegisterClusterRoutes to core/http/routes beside every other
registrar, folds AutoMigrate and the epoch sequence into one
cluster.Migrate, and turns the peer route's auth-coverage spec into a real
assertion: it drives the request through the actual auth middleware
instead of comparing two string constants, which the old spec would have
passed even with the exemption deleted.

88edd7fc7f fix(distributed): run cold model loads as durable jobs instead of holding the advisory lock (#11514)
* fix(advisorylock): set statement_timeout alongside lock_timeout

WithLockCtx already overrides a deployment-wide lock_timeout on its

* feat(distributed): add ModelLoadJob, the durable cold-load record

A cold load in distributed mode is a long-running background job, but it
was modelled as a synchronous side effect of an inference request: the
whole of it (backend install, multi-GB staging, checkpoint load) ran
inside the per-model advisory lock. Loading a 35.7 GB GGUF held that lock
for ~20 minutes, so every concurrent request for the same model blocked
on pg_advisory_lock and died at the role's 60s statement_timeout.

Introduce the row that lets the lock shrink to a decision. Exactly one
ModelLoadJob may be active per tracking key; that uniqueness — not the
lifetime of a lock — is what de-duplicates concurrent loaders across
replicas. ClaimLoadJob does its read-then-write under the advisory lock
and nothing else: no network, file or gRPC I/O inside the guarded
section, so a claim costs milliseconds no matter how long the resulting
load takes.

LastProgress is a heartbeat rather than a byte counter. A checkpoint load
legitimately moves zero bytes for many minutes, so a reaper keyed on byte
movement would reclaim a healthy job mid-load; byte progress stays the
concern of load_deadline.go. A job whose heartbeat stops for longer than
the orphan window is reclaimable, so a replica killed mid-load cannot
wedge a model permanently.

Failed jobs keep their row for a short grace so an immediately-following
request reports the real cause instead of silently starting a fresh load
of a model that just failed.

No caller yet — the router moves onto this in the next commit.

* refactor(distributed): run cold loads as jobs, outside the advisory lock

Route wrapped the entire cold load — node selection, backend install,
multi-GB staging and the remote LoadModel — in the per-model advisory
lock. The lock's job is to de-duplicate concurrent loaders, a decision
that takes milliseconds; holding it for the tens of minutes the resulting
work takes is what turned a dedup mechanism into a cluster-wide outage
for that model.

Split it into a claim and a run. The claim is the only thing left inside
the lock. The run is a background job owned by the claiming replica and
bounded by the same progress-extended deadline as before; every other
request for that model — local or on another replica — attaches as a
waiter and is served the moment the model is ready, with no duplicate
load and no lock contention.

Waiters share one broadcast rather than an ordered queue: they all want
the identical outcome, so ordering them would add fairness machinery that
changes no result. The local channel wakes same-replica waiters instantly
and a 2s DB poll is the authority, because a waiter on another replica
has no channel to close. On wake a waiter re-runs the warm path rather
than trusting the signal — the model may have been evicted in between.

A waiter whose client disconnects returns immediately and the job keeps
running; it belongs to the job record, not to the request. A failure is
recorded on the row so every waiter reports the real cause, and the row
survives briefly so the next request does not read "no job" as "not
loading" and start a duplicate load of a model that just failed.

The runner heartbeats the row on a fixed interval whether or not bytes
are moving, which is what keeps a legitimately silent checkpoint load
from being reclaimed as an orphan. Phase (installing/staging/loading) and
placement ride to the heartbeat on the context, the same seam
load_deadline.go already uses, so single-host paths are untouched.

Non-distributed mode (no DB) keeps the inline load exactly as it was.

* feat(distributed): bound the wait for a loading model and answer with progress

A request whose model is cold-loading now attaches to the running job and
is served the moment the model is ready. That wait has to be bounded: a
held HTTP request cannot survive real infrastructure, and an ingress or LB
idle timeout kills a twenty-minute request regardless of what LocalAI
does.

New LOCALAI_MODEL_LOAD_WAIT (default 60s) bounds the CALLER, never the
load — the job keeps running either way. On expiry the request gets 503
with Retry-After and a structured body naming the model, the node, the
phase, byte progress and an ETA. The `error` envelope keeps OpenAI
clients working; `loading` is additive so they ignore it.

The ETA comes from the job's own observed rate and is omitted rather than
guessed until enough bytes have moved for that rate to mean anything: a
confidently wrong ETA on a twenty-minute wait is worse than none.
Retry-After is that ETA when known, clamped to [5s, 300s], and the wait
budget otherwise.

LOCALAI_MODEL_LOAD_WAIT=0 waits unbounded, for deployments with no proxy
in front. Zero in the config struct still means "unset, use the default",
so the CLI records the operator's zero as ModelLoadWaitUnbounded rather
than losing the distinction.

The distributed branch of ModelLoader.loadModel wrapped the router's
error with %s, which flattened it to a string. Use %w: the typed error is
what the HTTP layer keys the 503 off.

* feat(api): add GET /api/models/{id}/load-status

A client that receives 503 while a model stages onto a worker needs
somewhere to poll. This returns the same `loading` object the 503 carries
— phase, node, byte progress and ETA — or 404 when no load is running.

Read-only and observability-shaped, so it is deliberately neither
admin-gated nor feature-gated: it explains a 503 the caller just
received, and hiding that behind a per-modality feature would make the
explanation for a failed image request depend on chat permissions. It
also gets no MCP tool, since there is nothing here an admin would manage
conversationally.

Registered on the surfaces from .agents/api-endpoints-and-auth.md: the
swagger block (existing `models` tag, so /api/instructions needs no new
area), the endpoint discovery maps in RegisterLocalAIRoutes, regenerated
swagger, and the distributed-mode docs page. No FLAG_* usecase is
involved, so capabilities.js is unchanged.

Assisted-by: Claude Opus 5 [claude-code]

* feat(ui): show cold-load progress in Chat and retry when the model is ready

A chat request for a model that is still staging onto a worker now gets a
503 carrying live progress instead of an error. Render it: the composer
shows the phase (installing / staging / loading), the node, the percent
and the ETA, then polls load-status and re-sends the request the moment
the model is ready.

Reuses the staging progress idiom the page already had rather than
inventing a second one — the two sources are folded into one
loadProgress, with the load job winning because it is authoritative
across frontend replicas and knows the phase, where the staging operation
only knows about a byte transfer this replica happens to be performing.

Waiting is bounded (three send attempts, ~30 min of polling each), so a
load that never finishes still surfaces as an error rather than as a
spinner nobody questions. An aborted generation stops the polling too.

Wraps localai-org/trellis2cpp (C++/GGML port of Microsoft TRELLIS.2,
pbr-textures branch) as a Go+purego backend, following the
stablediffusion-ggml pattern:

- backend/go/trellis2cpp: purego bindings to the flat C ABI (v9,
  asserted at startup), eager pipeline load with model-set validation
  (refuses non-trellis GGUFs; degrades coarse/geometry-only/textured
  exactly like the upstream demo), Generate3D via t2_generate +
  t2_bake_glb writing a binary glTF to dst. Weight-free unit tests
  cover resolution/validation/param mapping — CI never downloads the
  multi-GB GGUF set or runs inference.
- CPU SIMD variants build into per-variant directories (the shared
  libggml sonames collide across variants, unlike sd-ggml's flat
  renamed-.so scheme); run.sh picks one via /proc/cpuinfo.
- CI wiring: backend-matrix entries (cpu, cuda12/13, vulkan
  amd64+arm64, l4t, l4t-cuda13, darwin metal), index.yaml meta +
  latest/master image entries, bump_deps tracking of the pbr-textures
  branch, changed-backends.js mapping, top-level Makefile targets.
- Importer: auto-detects trellis GGUF repos/URIs (registered before
  llama-cpp so the .gguf match isn't stolen) and expands any trellis
  URI to the full 10-file component set spanning the three LocalAI-io
  HF repos.
- Gallery: trellis2-4b (full PBR + 1024 cascade) and
  trellis2-4b-geometry (512 untextured) with verified sha256s.

  renderer (quaternion trackball, metallic-roughness PBR, ACES,
  hidden-line wireframe with a bounded index budget) and pairs it with
  a minimal GLB parser for the two forms t2_bake_glb emits — dense
  vertex-PBR (linear COLOR_0 + _METALLIC_ROUGHNESS, uploaded as
  normalized integers) and the opt-in UV-atlas textured form. Parsing
  happens before any GL so stats and errors render without WebGL2.
- use3DHistory stores past generations (params, input thumbnail, and
  the GLB blob itself) in IndexedDB with keep-newest-20 eviction —
  GLBs are multi-MB binaries localStorage can't hold — and the page
  offers a download button for the active GLB.
- Wiring: CAP_3D capability constant (FLAG_3D — the exact string
  /api/models/capabilities serves), threeDApi, router entries, Studio
  tab, vite dev proxy, en locale keys.
- e2e: render-smoke entry plus a focused spec that feeds a real
  one-triangle vertex-PBR GLB through the parser/viewer and exercises
  IndexedDB persistence, selection, deletion, and API errors.

mudler's LocalAI [bot]andEttore Di Giacinto ff299df453 perf(http): gzip responses, cache hashed assets, bound the trace endpoints (#11056)
Three measured HTTP-layer regressions on a live deployment, fixed together
because they all shape the bytes on the wire.

1. No compression. The server sent no Content-Encoding regardless of what
   the client asked for, confirmed with curl straight at 127.0.0.1:8080 so
   it was not an ingress artefact. Adds gzip middleware, on by default and
   configurable via LOCALAI_DISABLE_HTTP_COMPRESSION and
   LOCALAI_HTTP_COMPRESSION_MIN_LENGTH (default 1024 bytes so tiny bodies
   are not wastefully wrapped). Streaming routes are skipped explicitly:
   an SSE Accept header, a WebSocket upgrade, and the completion / SSE /
   log-tail path prefixes, because whether a completion request streams is
   decided by the request body, which the middleware runs too early to see.
   Already-compressed formats (woff2, png, mp4, ...) are skipped too; gzip
   made those marginally larger. Measured over the embedded React build:
   JS+CSS 2815 KB raw to 808 KB gzipped (3.48x).

2. No cache headers on content-hashed assets. Vite hashes the filenames,
   so a given /assets/ URL can never change content, yet they shipped with
   no Cache-Control, ETag or Last-Modified, and the browser re-fetched the
   whole bundle on every navigation with no conditional request available.
   /assets/* now carries public, max-age=31536000, immutable. index.html
   stays no-cache so a deploy is picked up, and the unhashed locale JSONs
   get a short TTL rather than the immutable one.

3. Unbounded trace endpoints. /api/traces returned 21,033,606 bytes in
   4.65s and /api/backend-traces 3,471,682 bytes in 1.50s, and the admin
   UI polls both every few seconds. The ring buffer holds up to 1024
   entries, each embedding full input_text payloads. Both list endpoints
   now take limit / offset / full, default to 50 entries, and strip the
   heavy fields (request and response bodies plus headers for API traces,
   body and data for backend traces) unless full=true. Every trace gets a
   process-lifetime ID and GET /api/traces/{id} and
   /api/backend-traces/{id} serve the full record, which is what the UI
   fetches when a row is expanded. The list body stays a JSON array;
   paging metadata rides in X-Total-Count, X-Trace-Offset and
   X-Trace-Limit. Reproducing the live shape in a test, the polled payload
   goes from 21,131,097 bytes to 7,201 bytes.

mudler's LocalAI [bot]andEttore Di Giacinto 65bdbc4ee3 fix(http): make /readyz reflect startup readiness, plus gitignore and coverage-ratchet fixes (#10989)
* fix(http): make /readyz reflect startup readiness instead of always 200

/readyz was registered as a static handler returning 200 unconditionally,
so it carried no information: it was green whenever it could be reached at
all. Readiness could not distinguish "serving" from "still starting", and
any future change that started the HTTP listener earlier would silently
turn the probe into a lie.

Track startup completion on the Application (atomic flag, flipped at the
very end of New() on the success path only) and have the readiness handler
consult it per request, returning 503 with a small JSON body while startup
is in progress. A nil readiness source fails open so embedders keep the
historical behaviour.

/healthz is deliberately left readiness-independent. Liveness and readiness
answer different questions, and failing liveness during a long preload makes
an orchestrator restart the pod mid-download so the preload never finishes.

This matters because since #10949 the startup preload materializes
HuggingFace artifacts for managed backends: tens of GB for a large model
(31 GB observed on a live cluster). Both probes stay in quietPaths and stay
exempt from auth.

Note the listener is still started only after New() returns, so today the
not-ready state is not observable over HTTP. Moving the listener earlier is
a separate, deliberate decision and is not made here.

* chore(gitignore): anchor the mock-backend pattern so its source dir is traversable

The bare `mock-backend` pattern matched the *directory*
tests/e2e/mock-backend/, not just the binary built into it. Git will not
descend into an ignored directory even for tracked files, so
`git add tests/e2e/mock-backend/main.go` required -f. This was hit while
working on #10970.

Anchor it to the artifact's full path. The built binary stays ignored (it is
also covered by tests/e2e/mock-backend/.gitignore) while the source directory
becomes traversable again.

Verified with `git check-ignore -v`: a new source file under
tests/e2e/mock-backend/ is no longer ignored, and the binary produced by
`make build-mock-backend` still is.

* chore(coverage): raise the coverage ratchet from 48.5% to 54.2%

The committed baseline had drifted well below reality: it still read 48.5%
while a full instrumented run measures 54.2%. A stale-low baseline makes the
gate meaningless — coverage could regress by more than 5 percentage points
and still pass.

Raising a ratchet is a deliberate act, not something to fold into an
unrelated fix, so it gets its own commit. The headroom was earned by tests
landed in #10946, #10947, #10948, #10949, #10956, #10967, #10968, #10970 and
#10975.

Measured with `make test-coverage` on this branch (the same instrumented run
`make test-coverage-baseline` uses: ginkgo over ./pkg and ./core plus the
in-process tests/e2e suite, --covermode=atomic, --coverpkg over core/... and
pkg/..., generated protobuf excluded). The run completed with exit 0 and zero
spec failures; the total was then written with the exact command the
test-coverage-baseline target uses:

  go tool cover -func=coverage/coverage.out \
    | awk '/^total:/{gsub(/%/,"",$NF); print $NF}' > coverage-baseline.txt

Verified afterwards with scripts/coverage-check.sh, which reports OK.

Note the measured figure includes the readiness specs added earlier on this
branch, so it is a demonstrated floor rather than an estimate.

mudler's LocalAI [bot]andEttore Di Giacinto b19afb192a fix(distributed): backend discovery hid GPU-only backends behind the controller's capability (#10947)
* fix(backends): list backends runnable on worker nodes in distributed mode

GET /backends/available filtered the gallery against the system state of
the host serving the request. In a distributed deployment that host is the
controller, which typically has no GPU, while the GPUs live on worker
nodes. Any meta backend whose capabilities map lacks a "default" (or "cpu")
key was therefore dropped from the listing entirely — longcat-video,
vllm-omni, ltx-video, parakeet, edgetam and qwentts were invisible in the
UI even though installing them by name on a GPU worker worked fine.

Workers now report their own meta-backend capability at registration and
the controller persists it on the node row. The controller cannot derive
it: OS-dependent capabilities (metal, darwin-x86, nvidia-l4t) and the CUDA
runtime refinements are only observable on the worker. Nodes registered
before this field existed fall back to a coarse capability derived from
their GPU vendor and VRAM.

Backend discovery then evaluates compatibility as the union over healthy
backend nodes, so a backend runnable on any node is offered while one no
node can run stays hidden. Each remote capability is evaluated through a
capability-pinned system state, otherwise a forced capability on the
controller image (LOCALAI_FORCE_META_BACKEND_CAPABILITY or
/run/localai/capability) would silently override every worker's verdict.
With no registered nodes the listing is byte-for-byte what it was, so
single-node deployments are unaffected.

Also fixes the same-root-cause misclassification in /api/operations, which
used the capability-filtered listing to decide whether an operation was a
backend or a model install. A GPU-only backend installing on a worker is
still a backend operation on the controller, so that lookup is now
unfiltered.

Discovery then evaluates compatibility as the union over healthy backend

run stays hidden. Each remote capability is evaluated through a

controller image (LOCALAI_FORCE_META_BACKEND_CAPABILITY or
/run/localai/capability) would silently override every worker's verdict.
With no registered nodes the listing is byte-for-byte what it was, so
single-node deployments are unaffected.

Four surfaces shared this root cause and are all routed through the same
helper now:

  - GET /backends/available
  - GET /api/fine-tuning/backends
  - GET /api/quantization/backends
  - /api/operations backend-vs-model classification, which additionally
    had no reason to filter by capability at all: a GPU-only backend
    installing on a worker is still a backend operation on the
    controller, so that lookup is now unfiltered.

LocalAI [bot]andEttore Di Giacinto 97175f4b5a feat(model): debounce model loads after a failure to stop retry-storms (#10728)
A client that keeps polling a model whose load fails (e.g. a backend that
crashes deterministically on init) triggered a fresh backend start on
every request: request -> load -> crash in ~10s -> 500, repeat on the
next poll. Each attempt could leak GPU/CUDA state, and under
LOCALAI_SINGLE_ACTIVE_BACKEND it kept stealing the active slot from
healthy models. The existing loading-coalesce map only dedups
*concurrent* loads, so sequential polls were never covered.

Track load failures per modelID in ModelLoader. After a load fails,
refuse fresh load triggers for that model until a cooldown elapses,
returning a typed ModelLoadCooldownError that the HTTP layer maps to 503
with a Retry-After header. The cooldown grows exponentially per
consecutive failure (base, doubling, capped at 5m) and resets on a
successful load. The coalesced follower-retry of an in-flight burst
bypasses the gate, so a genuinely concurrent burst still gets its one
retry -- only new, independent triggers are refused, matching the
report's "refuse new load-triggers" wording.

Configurable via --model-load-failure-cooldown /
LOCALAI_MODEL_LOAD_FAILURE_COOLDOWN (default 10s, 0 disables), plumbed
through ApplicationConfig and applied unconditionally at startup.

Closes #10719

LocalAI [bot]andEttore Di Giacinto d7d7721eae feat(distributed): SyncedMap component + migrate finetune/quant/agent-tasks to cross-replica state (#10542)
* feat(distributed): add SyncedMap cross-replica in-memory state component

Introduce core/services/syncstate.SyncedMap[K,V]: a thread-safe in-memory map
that keeps itself consistent across frontend replicas via NATS, with an optional
pluggable durable Store and hydrate-from-source convergence.

Several features keep process-local state surfaced to the API (finetune/quant
jobs, agent tasks, model configs) and each hand-wired the same in-memory + NATS
broadcast + read-through-store legs - or forgot to, reintroducing cross-replica
staleness. SyncedMap makes that consistency a configuration choice:

- local writes mutate the map, write through the Store, then broadcast a delta;
- the apply path is memory-only and never re-publishes or re-writes the Store
  (structural echo-loop guard, mirroring galleryop.mergeStatus);
- on Start and on NATS reconnect the map re-hydrates from the source (Store, else
  Loader); an optional periodic Reconcile repairs silent drift;
- standalone mode (nil NATS client) is a strict in-memory no-op.

Reconnect re-hydrate is wired via a new *messaging.Client.OnReconnect callback,
consumed through an optional type-assertion so MessagingClient stays minimal.
Adds messaging.SubjectSyncStateDelta and a reusable testutil.FakeBus (synchronous
in-process MessagingClient with wildcard matching) for adopter tests.

Component only; service migrations follow in subsequent commits.

* refactor(finetune): back jobs with SyncedMap for cross-replica consistency

FineTuneService kept jobs in a process-local map and, although it wrote them to
Postgres, ListJobs/GetJob never read the store back and the wired natsClient was
never used - so in distributed mode a job created on one replica was invisible to
the others. Replace the map and the dead client with a syncstate.SyncedMap keyed
by job ID, value *schema.FineTuneJob (the exact REST shape, so responses are
unchanged).

- Add a Store adapter (core/services/finetune/syncstore.go) over FineTuneStore,
  plus FineTuneStore.ListAll (global hydrate; per-user List kept) and an

* refactor(agentpool): back agent tasks with SyncedMap for cross-replica consistency

AgentJobService.ListTasks read the process-local tasks map only, while ListJobs
already read through the DB persister + dispatcher NATS - so in distributed mode
a task created on one replica was invisible to the others. Back tasks with a
syncstate.SyncedMap keyed by task ID (value schema.Task, the exact REST shape);
jobs are left untouched.

- Store adapter (task_syncstore.go) over the existing JobPersister
  (LoadTasks/SaveTask/DeleteTask); reads svc.persister/userID live so a persister
  swap needs no rebuild. No new persister methods required.
- Task reads -> SyncedMap.List/Get; create/update -> Set (write-through +
  broadcast); delete -> Delete. The file persister now owns its own task set so
  the write-through path does not re-enter the SyncedMap lock (deadlock guard).
- The distributed NATS client is not available at construction (start() precedes
  initDistributed), so it is injected via SetTaskSyncNATS, which rebuilds the
  still-empty map before Start/hydrate. Wired at the main, restart, and per-user
  (UserServicesManager) distributed sites.

* refactor(quantization): back jobs with SyncedMap + durable QuantStore

durable cluster-wide. Back jobs with a syncstate.SyncedMap keyed by job ID
(value *schema.QuantizationJob, the exact REST shape).

- New distributed.QuantStore (GORM, table quantization_jobs) mirroring
  FineTuneStore: Create/Get/ListAll/Upsert(idempotent)/Delete, registered for
  AutoMigrate via distributed.InitStores (Stores.Quant).
- New adapter (quantization/syncstore.go) over QuantStore implementing
  syncstate.Store, with record<->schema conversion.
- Reads go through List/Get, writes through Set/Delete (write-through +
  broadcast); state.json is kept as the standalone Loader for single-node restart
  recovery (stale-job fixups preserved).
- app.go passes the distributed NATS client + QuantStore when distributed, nil
  otherwise; Start/Close lifecycle mirrors finetune.

Adds the real-infrastructure counterpart to the fake-bus unit tests, in the

instances stand in for two frontend replicas - each with its OWN NATS connection
to a shared server and a SHARED Postgres store (the distributed-mode invariant) -
and assert, over the wire:

- a create on replica A is observed by replica B;
- an update and a delete propagate A -> B (delete prunes, which a reload cannot);
- a late-joining replica recovers a job it never received a delta for, via store
  hydrate on Start (the at-most-once gap a fake bus cannot exercise);
- a local Set is written through to the shared Postgres store.

* fix(distributed): correct NATS JWT scoping and harden client auth

The JWT-auth path added in 46467cc7 had several gaps that fail silently
under LOCALAI_NATS_REQUIRE_AUTH:

- Agent-worker minted JWTs did not allow the subjects the agent worker
  actually subscribes to (jobs.mcp-ci.new and nodes.<id>.backend.stop),
  so MCP-CI jobs and backend-stop session cleanup were silently dropped.
  Scope the agent permission set to those subjects.
- NATS subscription permission violations were swallowed (Subscribe
  returned a live-but-dead subscription). Confirm subscriptions with a
  server round-trip so a denial surfaces synchronously, and log async
  permission errors.
- The backend worker connected anonymously when given a JWT without its
  paired seed; reject the unpaired credential instead.
- The documented service-user permissions in nats-auth-setup.sh omitted
  prefixcache.>, which the frontend publishes and subscribes; add it.

Also: add a credential-provider hook to the messaging client (consumed by
the follow-up credential-lifecycle change), drop the always-nil error from
NatsMessagingOptions, run go mod tidy (jwt/v2 and nkeys are now direct),
and gofmt the feature's files.

Tests: an agent-JWT e2e spec that connects to the enforcing NATS server
and exercises every subscription the agent worker makes, plus permission
allow-list coverage unit tests.

* feat(distributed): acquire and auto-refresh worker NATS credentials

Workers fetched NATS credentials once at startup, which broke two cases
under JWT auth: a worker that registered while still pending admin
approval never received a minted JWT (it connected unauthenticated and
gave up), and a long-running worker's 24h JWT expired with no way to renew
it.

Introduce workerregistry.NATSCredentialManager, built on idempotent
re-registration (the frontend preserves the node row and mints a fresh JWT
each call):

- Acquire re-registers through admin approval until the node is approved
  and credentials are minted (or returns the first success when auth is
  not required, preserving anonymous-NATS behavior).
- RefreshLoop re-registers before the JWT expires (~75% of its lifetime),
  updating the credentials served to the connection.
- Both are bounded (default 100 attempts / consecutive failures) and
  return an error on exhaustion, so an unapprovable or unrenewable worker
  exits non-zero and surfaces the problem instead of hanging or drifting
  toward an expired credential.

The messaging client gains WithUserJWTProvider, fetching credentials on
each (re)connect so the connection transparently adopts a refreshed JWT
when the server expires the old one. RegisterFull exposes the approval
status and full response; Register delegates to it.

Both the backend worker and the agent worker are wired to this: explicit
env credentials are used as-is, minted credentials are acquired-with-wait
and refreshed, and a permanent refresh failure shuts the worker down so it
restarts and re-acquires.

Tests cover Acquire (wait-through-pending, bounded give-up, context
cancel), RefreshLoop (refresh-before-expiry, bounded failure, no-expiry
exit) and jwtExpiry decoding. Docs updated in distributed-mode.md.

LocalAI [bot]andEttore Di Giacinto 8d6548c0b9 fix(distributed): sync gallery OpCache + caches across frontend replicas (#9983)
When the LocalAI frontend deployment is scaled past one replica, the UI's
/api/operations poll round-robins between pods. Each pod kept the OpCache
(galleryID->jobID), OpStatus map, and the post-install in-memory caches
(ModelConfigLoader, UpgradeChecker) purely in-process. Reads never
consulted PostgreSQL or NATS even though writes already published to PG.
Symptoms:

- A user installing a model on replica A saw the operation card flicker
  in and out as the load balancer alternated.
- The Models page re-fetched the whole gallery on every flicker because
  useEffect([operations.length]) re-fires when the count changes.
- A chat completion that landed on replica B after the install completed
  on replica A failed to find the new model — B's ModelConfigLoader was
  still the old one because nothing told it to reload from disk.
- The UpgradeChecker 6-hour cache stayed stale on peer replicas after a
  backend upgrade, so /api/backends/upgrades kept surfacing an upgrade
  that had already shipped.

Mirror the jobs Dispatcher pattern for gallery ops:

- OpCache learns SetMessagingClient/SetGalleryStore + a Start(ctx) that
  hydrates from PostgreSQL and subscribes to gallery.opcache.{start,end}.
  Set/SetBackend now upsert cache_key + is_backend_op on the gallery_
  operations row and broadcast OpCacheEvent so peers merge it in. The
  hydrate path uses a new GalleryStore.ListActive() (status in {pending,
  downloading, processing} and updated within 30 min).
- GalleryService.SubscribeBroadcasts wires a SubjectGalleryProgress-
  Wildcard subscriber that calls a new lock-light mergeStatus into the
  local statuses map, plus a SubjectGalleryCancelWildcard subscriber that
  runs the locally-registered cancel func. Hydrate() restores active rows
  from PostgreSQL on startup so a freshly-started replica is not
  observably empty mid-install. CancelOperation tolerates the cancel func
  living on a different replica and publishes anyway.
- modelHandler and backendHandler publish on the new
  SubjectCacheInvalidateModels / SubjectCacheInvalidateBackends after
  a successful install/delete/upgrade. SubscribeBroadcasts wires peers
  to refresh: OnModelsChanged (re-runs LoadModelConfigsFromPath) and
  OnBackendOpCompleted (re-triggers UpgradeChecker). The originating
  replica reloads inline so it never enters the broadcast handler.
- OpStatus.Error (an error interface) flat-marshalled to "{}" over JSON,
  so a failed install replicated to a peer arrived with a nil error and
  the UI's failure banner never appeared. Add MarshalJSON/UnmarshalJSON
  via an opStatusWire shim that round-trips Error as a string.
- UpdateStatus and CancelOperation now drop the mutex before publishing
  to NATS or persisting to PostgreSQL. The wildcard subscriber's
  mergeStatus loops back into the same service on the publishing replica
  and would deadlock otherwise; this also prevents future PG round-trips
  from stalling concurrent readers on every progress tick.

Tests cover the OpStatus error round-trip, OpCache propagation through a
shared in-memory bus, OpCache PostgreSQL hydration (active-only),
GalleryService progress + cancel broadcast, Nodes preservation across a
peer's bare progress tick, GalleryService hydration from PG, and the
two cache-invalidation broadcasts (models + backends). 44 specs total
in galleryop; routes/operations specs and jobs/agents suites still pass.

- Adds the cap to add() so saturation drops new records (rate-limited
  warn at 1/1024) instead of growing unbounded.
- Raises usageMaxPending to 50000 to absorb realistic inference bursts.
- Replaces the package-level batcher global with a mutex-guarded pair
  plus a currentBatcher() accessor so Init / Shutdown cycles are
  race-free.
- Adds ShutdownUsageRecorder() for graceful drain on process exit
  (not yet wired into app shutdown, just published).
- Adds FlushNow() for deterministic tests; the middleware suite no
  longer needs 6s sleeps per spec and now runs in ~50ms instead of 18s.

AdiraandEttore Di Giacinto c2fe0a6475 fix(http): honor X-Forwarded-Prefix when proxy strips the prefix (#9614)
* fix(http): honor X-Forwarded-Prefix when proxy strips the prefix

Closes #9145.

Two related issues kept the React UI from loading when a reverse proxy
rewrites a sub-path with prefix-stripping (e.g. Caddy `handle_path`):

1. `BaseURL` only computed a prefix from the path StripPathPrefix had
   removed, so when the proxy strips the prefix before forwarding, the
   request arrives without it and the base URL was returned without a
   prefix. Extract a `BasePathPrefix` helper and add an
   `X-Forwarded-Prefix` header fallback so the prefix is recovered.
2. `<base href>` only changes how relative URLs resolve; the build
   emits path-absolute references like `/assets/...` and
   `/favicon.svg`, which still resolve against the origin and bypass
   the proxy prefix. Rewrite those references in the served

Adds unit coverage for `BaseURL` with a pre-stripped path and an

* fix(http): gate X-Forwarded-Prefix through SafeForwardedPrefix in BasePathPrefix

BasePathPrefix consumed X-Forwarded-Prefix directly, so a value the
codebase elsewhere rejects (e.g. "//evil.com") slipped through and was
interpolated into the SPA index.html — both into the path-absolute asset
URL rewrite in serveIndex (turning "/assets/..." into "//evil.com/assets/...",
a protocol-relative URL that loads JS from a foreign origin) and into
<base href>. Route the header through the existing SafeForwardedPrefix
validator that StripPathPrefix and prefixRedirect already use, and
HTML-escape the prefix before injecting it into the asset rewrite as
defense in depth against attribute breakout.

Tests cover //evil.com, backslashes, control chars, CR/LF and a missing
leading slash; the integration test asserts an unsafe prefix can't poison
asset URLs.

Richard Palethorpe 670259ce43 chore: Security hardening (#9719)
* fix(http): close 0.0.0.0/[::] SSRF bypass in /api/cors-proxy

The CORS proxy carried its own private-network blocklist (RFC 1918 + a
handful of IPv6 ranges) instead of using the same classification as
pkg/utils/urlfetch.go. The hand-rolled list missed 0.0.0.0/8 and ::/128,
both of which Linux routes to localhost — so any user with FeatureMCP
(default-on for new users) could reach LocalAI's own listener and any
other service bound to 0.0.0.0:port via:

  GET /api/cors-proxy?url=http://0.0.0.0:8080/...
  GET /api/cors-proxy?url=http://[::]:8080/...

Replace the custom check with utils.IsPublicIP (Go stdlib IsLoopback /
IsLinkLocalUnicast / IsPrivate / IsUnspecified, plus IPv4-mapped IPv6
unmasking) and add an upfront hostname rejection for localhost, *.local,
and the cloud metadata aliases so split-horizon DNS can't paper over the
IP check.

The IP-pinning DialContext is unchanged: the validated IP from the
single resolution is reused for the connection, so DNS rebinding still
cannot swap a public answer for a private one between validate and dial.

Regression tests cover 0.0.0.0, 0.0.0.0:PORT, [::], ::ffff:127.0.0.1,
::ffff:10.0.0.1, file://, gopher://, ftp://, localhost, 127.0.0.1,
10.0.0.1, 169.254.169.254, metadata.google.internal.

* fix(downloader): verify SHA before promoting temp file to final path

DownloadFileWithContext renamed the .partial file to its final name
*before* checking the streamed SHA, so a hash mismatch returned an
error but left the tampered file at filePath. Subsequent code that
operated on filePath (a backend launcher, a YAML loader, a re-download
that finds the file already present and skips) would consume the
attacker-supplied bytes.

Reorder: verify the streamed hash first, remove the .partial on
mismatch, then rename. The streamed hash is computed during io.Copy
so no second read is needed.

While here, raise the empty-SHA case from a Debug log to a Warn so
"this download had no integrity check" is visible at the default log
level. Backend installs currently pass through with no digest; the
warning makes that footprint observable without changing behaviour.

Regression test asserts os.IsNotExist on the destination after a
deliberate SHA mismatch.

* fix(auth): require email_verified for OIDC admin promotion

extractOIDCUserInfo read the ID token's "email" claim but never
inspected "email_verified". With LOCALAI_ADMIN_EMAIL set, an attacker
who could register on the configured OIDC IdP under that email (some
IdPs accept self-supplied unverified emails) inherited admin role:

  - first login:  AssignRole(tx, email, adminEmail) → RoleAdmin
  - re-login:     MaybePromote(db, user, adminEmail) → flip to RoleAdmin

Add EmailVerified to oauthUserInfo, parse email_verified from the OIDC
claims (default false on absence so an IdP that omits the claim cannot
short-circuit the gate), and substitute "" for the role-decision email
when verified=false via emailForRoleDecision. The user record still
stores the unverified email for display.

GitHub's path defaults EmailVerified=true: GitHub only returns a public
profile email after verification, and fetchGitHubPrimaryEmail explicitly
filters to Verified=true.

Regression tests cover both the helper contract and integration with
AssignRole, including the bootstrap "first user" branch that would
otherwise mask the gate.

* feat(cli): refuse public bind when no auth backend is configured

When neither an auth DB nor a static API key is set, the auth
middleware passes every request through. That is fine for a developer
laptop, a home LAN, or a Tailnet — the network itself is the trust
boundary. It is not fine on a public IP, where every model install,
settings change, and admin endpoint becomes reachable from the
internet.

Refuse to start in that exact configuration. Loopback, RFC 1918,
RFC 4193 ULA, link-local, and RFC 6598 CGNAT (Tailscale's default
range) all count as trusted; wildcard binds (`:port`, `0.0.0.0`,
`[::]`) are accepted only when every host interface is in one of those
ranges. Hostnames are resolved and treated as trusted only when every
answer is.

A new --allow-insecure-public-bind / LOCALAI_ALLOW_INSECURE_PUBLIC_BIND
flag opts out for deployments that gate access externally (a reverse
proxy enforcing auth, a mesh ACL, etc.). The error message lists this
plus the three constructive alternatives (bind a private interface,
enable --auth, set --api-keys).

The interface enumeration goes through a package-level interfaceAddrsFn
var so tests can simulate cloud-VM, home-LAN, Tailscale-only, and
enumeration-failure topologies without poking at the real network
stack.

* test(http): regression-test the localai_assistant admin gate

ChatEndpoint already rejects metadata.localai_assistant=true from a
non-admin caller, but the gate was open-coded inline with no direct
test coverage. The chat route is FeatureChat-gated (default-on), and
the assistant's in-process MCP server can install/delete models and
edit configs — the wrong handler change would silently turn the LLM
into a confused deputy.

Extract the gate into requireAssistantAccess(c, authEnabled) and pin
its behaviour: auth disabled is a no-op, unauthenticated is 403,
RoleUser is 403, RoleAdmin and the synthetic legacy-key admin are
admitted.

No behaviour change in the production path.

* test(http): assert every API route is auth-classified

The auth middleware classifies path prefixes (/api/, /v1/, /models/,
etc.) as protected and treats anything else as a static-asset
passthrough. A new endpoint shipped under a brand-new prefix — or a
new path that simply isn't on the prefix allowlist — would be
reachable anonymously.

Walk every route registered by API() with auth enabled and a fresh
in-memory database (no users, no keys), and assert each API-prefixed
route returns 401 / 404 / 405 to an anonymous request. Public surfaces
(/api/auth/*, /api/branding, /api/node/* token-authenticated routes,
/healthz, branding asset server, generated-content server, static
assets) are explicit allowlist entries with comments justifying them.

Build-tagged 'auth' so it runs against the SQLite-backed auth DB
(matches the existing auth suite).

* test(http): pin agent endpoint per-user isolation contract

agents.go's getUserID / effectiveUserID / canImpersonateUser /
wantsAllUsers helpers are the single trust boundary for cross-user
access on agent, agent-jobs, collections, and skills routes. A
regression there is the difference between "regular user reads their
own data" and "regular user reads anyone's data via ?user_id=victim".

Lock in the contract:
  - effectiveUserID ignores ?user_id= for unauthenticated and RoleUser
  - effectiveUserID honours it for RoleAdmin and ProviderAgentWorker
  - wantsAllUsers requires admin AND the literal "true" string
  - canImpersonateUser is admin OR agent-worker, never plain RoleUser

No production change — this commit only adds tests.

endpoint is admin-only but the buffer is reachable via any heap-style
introspection and the captured tokens otherwise outlive the request.
Strip those header values at capture time. Body redaction is left to a
follow-up — the prompts are usually the operator's own and JSON-walking
is invasive.

Distribution tokens were also logged in plaintext from
core/explorer/discovery.go; logs forward to syslog/journald and outlive
the token. Redact those to a short prefix/suffix instead.

60/min/IP limiter for /api/auth/{github,oidc}/callback so callbacks are

* feat(http): XSS hardening — CSP headers, safe href, base-href escape, SVG sandbox

Several closely related XSS-prevention changes spanning the SPA shell, the
React UI, and the branding asset server:

- New SecurityHeaders middleware sets CSP, X-Content-Type-Options,
  X-Frame-Options, and Referrer-Policy on every response. The CSP keeps
  script-src permissive because the Vite bundle relies on inline + eval'd
  scripts; tightening that requires moving to a nonce-based policy.

- The <base href> injection in the SPA shell escaped attacker-controllable
  Host / X-Forwarded-Host headers — a single quote in the host header
  broke out of the attribute. Pass through SecureBaseHref (html.EscapeString).

- Three React sinks rendering untrusted content via dangerouslySetInnerHTML
  switch to text-node rendering with whiteSpace: pre-wrap: user message
  bodies in Chat.jsx and AgentChat.jsx, and the agent activity log in
  AgentChat.jsx. The hand-rolled escape on the agent user-message variant
  is replaced by the same plain-text path.

- New safeHref util collapses non-allowlisted URI schemes (most
  importantly javascript:) to '#'. Applied to gallery `<a href={url}>`
  links in Models / Backends / Manage and to canvas artifact links —
  these come from gallery JSON or assistant tool calls and must be treated
  as untrusted.

- The branding asset server attaches a sandbox CSP plus same-origin CORP
  to .svg responses. The React UI loads logos via <img>, but the same URL
  is also reachable via direct navigation; this prevents script
  execution if a hostile SVG slipped past upload validation.

* feat(http): bound HTTP server with read-header and idle timeouts

A net/http server with no timeouts is trivially Slowloris-able and leaks
idle keep-alive connections. Set ReadHeaderTimeout (30s) to plug the
slow-headers attack and IdleTimeout (120s) to cap keep-alive sockets.

ReadTimeout and WriteTimeout stay at 0 because request bodies can be
multi-GB model uploads and SSE / chat completions stream for many
minutes; operators who need tighter per-request bounds should terminate
slow clients at a reverse proxy.

those fields. Lock that down with a regression test so a future
"let's just c.Bind(&user)" refactor breaks loudly.

UploadToCollectionForUser handed the filename to a vendored backend
without sanitising at all.

Strip to filepath.Base at both boundaries and reject the trivial
unsafe values ("", ".", "..", "/").

scheme, header keys/values must be control-char-free. Drop anything

/browse/* into a 301 to //evil.com/app. The path-strip middleware had
the same shape on its prefix-trailing-slash redirect.

Add SafeForwardedPrefix at the middleware boundary: must start with
a single '/', no protocol-relative '//' opener, no scheme, no
backslash, no control characters. Apply at both consumers; misconfig
trips the validator and the header is dropped.

exploitable (cookies aren't sent under wildcard CORS), but the
misconfiguration trap is worth closing. Skip the registration and warn.

* feat(auth): zxcvbn password strength check with user-acknowledged override

The previous policy was len < 8, which let through "Password1" and the
rest of the credential-stuffing corpus. LocalAI has no second factor
yet, so the bar needs to sit higher.

Add ValidatePasswordStrength using github.com/timbutler/zxcvbn (an
actively-maintained fork of the trustelem port; v1.0.4, April 2024):
- min 12 chars, max 72 (bcrypt's truncation point)
- reject NUL bytes (some bcrypt callers truncate at the first NUL)
- require zxcvbn score >= 3 ("safely unguessable, ~10^8 guesses to
  break"); the hint list ["localai", "local-ai", "admin"] penalises
  passwords built from the app's own branding

zxcvbn produces false positives sometimes (a strong-looking password
that happens to match a dictionary word) and operators occasionally
need to set a known-weak password (kiosk demos, CI rigs). Add an
acknowledgement path: PasswordPolicy{AllowWeak: true} skips the
entropy check while still enforcing the hard rules. The structured
PasswordErrorResponse marks weak-password rejections as Overridable
so the UI can surface a "use this anyway" checkbox.

Wired through register, self-service password change, and admin
password reset on both the server and the React UI.

no toast, no fetch, no clue. Reproducible by typing fewer than 12
chars on the second password change of a session.

The JS-level length check in handleSubmit already shows a toast and
the server rejects with a structured error, so the HTML5 attribute
was redundant defence anyway. Drop it.

right fix is to stop reaching out to a third-party CDN for fonts on
every page load.

Add @fontsource-variable/geist and @fontsource-variable/geist-mono as
npm deps and import them once at boot. Drop the <link rel="preconnect">
and external stylesheet from index.html.

* feat(auth): make password length-floor overridable like the entropy check

The 12-char minimum was a policy choice, not a technical invariant —
only "non-empty", "<= 72 bytes", and "no NUL bytes" are real bcrypt
constraints. Treating length-12 as a hard rule was inconsistent with
the entropy check (already overridable) and friction for use cases
where the account is just a name on a session, not a security
boundary (single-user kiosk, CI rig, lab demo).

Restructure ValidatePasswordStrength:
- Hard rules (always enforced): non-empty, <= MaxPasswordLength, no NUL byte
- Policy rules (skipped when AllowWeak=true): length >= 12, zxcvbn score >= 3

PasswordError now marks password_too_short as Overridable too. The
React forms generalised from `error_code === 'password_too_weak'` to
`overridable === true`, and the JS-side preflight length checks were
removed (server is source of truth, returns the same checkbox flow).

LocalAI [bot]andEttore Di Giacinto cec5c4fdfc fix(http): make handler-error status visible in access log + transcription errors (#9707)
* fix(http): log accurate status code when handler returns error

The custom xlog access-log middleware in API() reads res.Status
*before* Echo's central HTTPErrorHandler runs, so when a handler
returns an error without writing a response (e.g.
TranscriptEndpoint's `return err` on backend failure) the status
field stays at its default 200. The logged line then claims
status=200 while the client receives 500 — silently hiding every
500/503/etc. that bubbles up through Echo's error handler.

Mirror echo.DefaultHTTPErrorHandler's status derivation when
err != nil and the response hasn't been committed: default to 500,
upgrade to *echo.HTTPError.Code if applicable. The logged status now
matches what the client actually sees, so failed transcription
requests stop appearing as 200 in the access log.

* fix(transcription): log underlying error before returning 500 to client

ModelTranscriptionWithOptions surfaces real failures — gRPC errors
from a remote node, model load problems, ffmpeg conversion crashes —
but TranscriptEndpoint just did `return err`, so Echo turned it into
a 500 with a generic body and the original error was lost. Operators
chasing transcription failures across distributed mode were left
with "upstream returned 500" on the client and zero context anywhere
in the frontend's logs.

Add an xlog.Error before returning, recording model name, the staged
audio path, and the underlying error. Combined with the access-log
status fix, a failing transcription now leaves an audit trail (real
status code in the access line, real cause in an Error line) instead
of vanishing.

Ettore Di Giacinto 87cf736068 feat(react-ui): add multilingual (i18n) support (#9642)
Adds end-to-end internationalization to the React UI with five seed
languages (English, Italian, Spanish, German, Simplified Chinese) and
a sidebar-footer language switcher next to the existing theme toggle.

Library: react-i18next + i18next + i18next-http-backend +
i18next-browser-languagedetector. The detector caches the user's
choice in localStorage (key `localai-language`, mirroring the existing
`localai-theme` convention) and updates the `<html lang>` attribute on
change. fallbackLng is `en`, so any missing translation in another
locale falls back transparently.

Translation files live under `public/locales/<lng>/<ns>.json`. They
ride along with the existing `//go:embed react-ui/dist/*` directive,
but the previous SPA route in core/http/app.go only exposed
`/assets/*` from the embedded React build. This commit generalizes
the asset handler into a `serveReactSubdir(subdir)` helper and adds a
matching `/locales/*` route so i18next-http-backend can fetch the
JSONs at runtime. The http-backend `loadPath` is built via the
existing `apiUrl()` helper so instances served under a sub-path (e.g.
`<base href="/ui/">`) resolve correctly.

Namespaces (13): common, nav, errors, auth, home, models, importModel,
chat, agents, skills, collections, media, admin. Translated UI surfaces
include the sidebar/header/footer chrome, login + account flows, the
Home dashboard (incl. the manage-by-chat assistant CTA), the model
gallery + import flow, the chat experience (Chat.jsx + ChatsMenu),
agents/skills/collections list pages, the studio media tabs (Image,
Video, TTS), and the admin page-headers (Settings incl. its section
nav, Manage, Backends, Traces, Nodes, P2P, Users, Usage). Shared
components (ConfirmDialog, Toast) take their default labels from the
common namespace so callers don't need to pass strings explicitly.

Tooling for incremental adoption is included:
  - `i18next-parser.config.js` + `npm run i18n:extract` to sweep `t()`
    keys into the JSON skeletons.
  - `scripts/translate-locales.mjs` (one-off helper) to bootstrap
    non-English locales from English source via OpenAI or Anthropic
    APIs, with --copy mode as a placeholder fallback. Idempotent;
    preserves existing translations unless --overwrite is passed.

Larger config-driven pages (ModelEditor, Settings deep field forms,
AgentChat/AgentCreate, SkillEdit, CollectionDetails, Talk, Sound,
biometrics, FineTune/Quantize, Users modals, Nodes/P2P install
pickers, BackendLogs, Traces deep filters, Explorer) intentionally
keep their inner content untranslated for now — they fall back to
English via fallbackLng so functionality is unaffected, and the
extracted-strings pattern + the bootstrap script make follow-up
extraction straightforward.

The initial Suspense fallback at the root in main.jsx covers the
first JSON fetch on cold load. A simple `.app-boot-spinner` styled
in App.css provides a non-empty paint while the first namespace
loads.
