* feat(3d): add Generate3D RPC, FLAG_3D capability, and /v1/3d/generations endpoint

Adds the plumbing for image-conditioned 3D asset generation (binary
glTF / GLB output), modeled on the video generation path:

- backend.proto: Generate3D RPC + Generate3DRequest (staged image src,
  glb dst, seed/step/cfg_scale/texture_steps, quality and background
  enums, params map for backend-specific extras)
- pkg/grpc: thread Generate3D through client, server, embed, base and
  the backend interfaces; connection-evicting and distributed-node
  wrappers (in-flight tracking + file staging) included
- core/config: FLAG_3D usecase (guessed only for the trellis2cpp
  backend), '3d' canonical usecase string mapped to the Generate3D
  method, and a '3d' output modality
- REST: POST /v1/3d/generations (+ unversioned alias) returning
  OpenAIResponse with a /generated-3d URL or b64_json; conditioning
  image accepted as URL, base64, or data URI; quality/background
  validated at the edge; .glb served as model/gltf-binary
- auth: '3d' route feature (default ON); /api/instructions entry

* feat(trellis2cpp): add the trellis2.cpp image-to-3D backend

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.

* feat(ui): 3D generation page with native GLB viewer and IndexedDB history

Adds a Studio tab + /app/3d page for the new image-to-3D endpoint:

- GlbViewer ports the trellis2cpp demo's dependency-free WebGL2
  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 0f7186f214 feat(ui): replace the stacked operations bar with a one-line strip and an Activity page (#11163)
* feat(ui): record finished gallery operations in a bounded history ring

The operations panel drops an operation the moment it succeeds, so a user
who steps away cannot tell whether an install finished, failed or was never
started. OpCache now keeps the last 50 terminal operations, recorded from
the point where an op leaves the cache.

* test(ui): pin the history ring's dedupe, outcome order and start stamp

Review of the history ring found four gaps. The dedupe guard and the
bounded seen set were unreachable through the exported API and so had no
coverage; an in-package spec file now drives opHistory directly. The
outcome switch claimed an ordering was load bearing that nothing pinned,
so an errored op that never reached Processed now has a spec.

Two behaviour fixes come with it. StartedAt was the zero time for ops
recovered from the store or replicated from a peer, since neither path
stamps a start time, which would have rendered as a two-millennia
duration; it now falls back to the finish time. Reusing a cache key with
a fresh job ID orphaned the previous stamp, so Set and SetBackend now
drop it.

The comment on the outcome switch described a state the code cannot be
in: CancelOperation sets Cancelled and Processed synchronously before the
handler removes the entry, so status.Cancelled already covers the cancel
endpoint. The !Processed clause stays for the dismiss endpoint firing on
an in-flight op, and the comments now say so.

* feat(ui): record operations that end on a peer replica

The NATS end event is the only signal a replica gets for an install another
replica ran. Record from applyEnd too, deduped by job ID so the originating
replica does not record its own broadcast twice.

Three start-stamp defects in the same path go with it. applyEnd now drops the
stamp unconditionally, since recordTerminal only cleans up on the path where it
found a cache key and an end event can overtake the local Set. applyStart drops
the stamp of the job whose cache key it replaces, which a peer-driven retry
previously stranded. And recordTerminal reads the stamp once instead of testing
Exists and then reading, so a concurrent record for the same job can no longer
delete the stamp between the two and let the zero time overwrite the
finish-time fallback, which the Activity page would render as a two-millennia
run.

* fix(ui): do not guess the outcome of a peer operation with no local status

A replica that restarts mid-operation hydrates its OpCache keys from
PostgreSQL, but gallery statuses are in-memory only and come back empty. The
end broadcast then landed on recordTerminal's nil-status branch, which reads a
missing status as queued-and-removed and filed a successful install as
cancelled. That reading is right locally and wrong on the peer path, where a
missing status means the outcome was never held here.

recordTerminal now takes the source of the terminal event and records nothing
when the peer path finds no status, restoring what the replica did before the
end event started recording. The local path is unchanged.

Also move the ApplyEndForTest seam to the conventional export_test.go, and stop
the dedupe spec from claiming to guard the ring's seen set: the local delete
removes the status keys, so the broadcast that follows returns before reaching
it. An in-package spec that calls recordTerminal twice does the pinning.

* fix(ui): detect operation departure by identity and ignore committing ops in the ETA gate

Refetching history on a shrinking live count missed a completion that
coincided with a start, which is the common case during a batch install.
Track the live job IDs instead, so any departure triggers the refetch
regardless of how the count moved.

An operation that has finished downloading stays live at
currentBytes == totalBytes for the whole commit and install phase and can
never produce an estimate, so counting it in the all-or-nothing gate blanked
every other operation's time remaining for as long as it lasted. Only
operations still moving bytes get a vote.

* fix(ui): let only downloading operations gate the time remaining estimate

Verifying pins an operation flat below its total for the whole sha256 pass:
the AfterDownload hook reports completedBytes plus the finished file against
a total summed over every file, then hashes synchronously without emitting
progress. Files download sequentially, so a 15 shard model enters that
window 14 times, and a byte comparison cannot see it because the counter is
genuinely below the total throughout.

Gating on phase closes resolving, verifying, committing and persisting in
one predicate, so a quiet neighbour no longer blanks every other
operation's estimate for minutes at a time. The byte clauses stay: a
producer can report downloading with bytes already at the total.

* fix(ui): keep the operations strip from widening the page and from muting a failure

A long install error made the strip report a 1600px minimum width, which sized
main-content to fit and gave every page under it a horizontal scrollbar.
Inline-size containment plus shrinkable detail and bytes cells keep it inside
the viewport.

Hiding is no longer able to swallow the hidden job's own failure, a completed
removal or staging says so instead of claiming an install, a cancelling
operation renders as cancelling, and the live region no longer covers the
per-second percentage.

* fix(ui): shrink main-content instead of containing the strip, and expose progress

min-width on .main-content is what actually lets a long install error shrink,
and unlike inline-size containment it has no browser support floor and no
latent collapse if the strip ever lands in a shrink-to-fit context. It matches
what .app-layout-chat .main-content already does, and it clears pre-existing
horizontal overflow on narrow viewports as a side effect.

The progress track is now a labelled progressbar, so assistive tech can read
the value on demand rather than losing it to the aria-hidden that stopped the
live region re-announcing every poll.

* feat(ui): add the live operation card for the Activity page

Carries the detail the one-line strip has to drop: phase, bytes, the per-node
breakdown for cluster installs, and a labelled Cancel button. Cancelling is
destructive, so it gets a labelled button rather than a glyph.

A cancelling operation drops its progress bar and its time estimate, the same
call the strip makes: a percentage still climbing under "Cancelling" reads as
the cancel not having taken.

* fix(ui): give the operation card a verb, live node disclosure and its per-node detail

The card carried no verb, so an install, a removal and a staging op rendered as
spinner plus name plus kind tag and were indistinguishable. It now runs the same
verb and icon chain as the one-line strip, which is what stops the page that is
meant to carry more detail from carrying less.

The auto-expand default was evaluated once at mount. An operation is listed as
soon as it is admitted but its nodes are filled in only when the fan-out starts
reporting, so a card mounted at creation latched on the empty list and stayed
collapsed. The default is a live expression now, and state holds only an
explicit choice.

Also: an optional onRetry gates a Retry button, so the page can own the install
reconstruction without the card ever showing a control with nothing behind it;
the disclosure moved above the region it controls and gained aria-controls; the
toggle is gated at more than one node so the count is never "1 nodes"; an
unmapped node status is passed through instead of being relabelled "Queued";
error text is clamped with the full string in the title; and file_name plus the
per-node progress bar are rendered again, reviving three CSS rules that had gone
dead along with the detail they styled.

* feat(ui): add the Activity page

Live operations, unacknowledged failures and the record of what finished, at
/app/activity in the Operate console. Cancelling an install now lives here
behind a labelled button rather than on the strip, and a failed install can be
retried: the retry dismisses the failure first so it still reaches the record,
then reissues the model, backend or node-scoped backend install.

The sidebar Operate entry carries the operation count. The console rail is only
rendered on an Operate route and can be collapsed, so a badge there could
vanish while operations were still running.

Two follow-ups from review fold in here: a failed removal or staging job no
longer reports a failed install on either the card or the strip, and the card's
error text can shrink so one unbroken token cannot widen the card.

* fix(ui): dismiss operations by job, and stop the Activity page contradicting itself

Dismissing resolved the job by display id, but /api/operations strips the
"node:<nodeID>:" prefix before emitting, so a local install and a node-scoped
install of one backend arrive as two jobs sharing one id. Dismissing by id
retired whichever came first. That defeated the guarantee retry was built
around: with the wrong job dismissed, the reinstall overwrote the acted-on
failure's opcache entry in place, bypassing recordTerminal, while an unrelated
failure vanished from Needs attention. dismissFailedOp, the card's dismiss
control and the strip now all pass the jobID, which is what the endpoint takes.

A filter matching nothing rendered the "nothing has ever run" empty state while
the header counted the records the filter had hidden. The empty state is now
gated on the All chip and a narrowed view gets its own message plus a way back;
the header counts the instance rather than the chip, so selecting Backends no
longer reports "Nothing running" over running model installs.

Also: the summary drops a zero clause instead of rendering "0 needs attention"
on the happy path and pluralises both counts; a record duration is floored at
"< 1s" and rejected above a day, so a zero-value start stamp cannot render a
span of millennia and a zero span cannot render "installed in" with nothing
after it; a deletion cancelled mid-flight reports the cancellation rather than
claiming it was removed; and the retry variant comment names the fix instead of
calling the gap closed.

the admin-only endpoint list, which also omitted the pre-existing
POST /api/operations/:jobID/dismiss.

Corrects the distributed-mode install-watching section: the per-node
breakdown now lives on the Activity page rather than on the strip, which
rolls a fan-out up into a single phrase.

* docs: correct nine details in the Activity page documentation

The operations strip never renders a file name: its detail line is the
error, the node roll-up, the target node, the phase or the queued note.
Drops the stale clause in the distributed-mode section, where the
per-node bullet is now the only place a file name is described.

Scopes the phase vocabulary to artifact-backed gallery models, since a
plain GGUF install emits no phase. Corrects the per-node list: the
toggle exists for any fan-out of two or more workers and the four-node
threshold only governs whether it starts open, while the N nodes tag
needs more than one node. Notes that a cancelled operation can sit in
the live section reading Cancelling, that cluster staging never reaches
the record, and that Clear history appears only when the record has
something in it.

Names the operations response envelope, with a JSON example, so callers
do not index a bare array, and stops describing the icon-only dismiss
control as a labelled button.

* docs: drop the unreachable Cancelling state and scope the byte claims

An operation can only report isCancelled while it is unprocessed, but
every writer of Cancelled sets Processed in the same breath, on the peer
path as much as the local one, and the cache evicts cancelled entries
before the handler sees them. The state cannot reach the page, so the
live section is described again as running or queued operations.

Byte counts come from the artifact bridge alone, the same producer as
the phase, so a plain GGUF install, a removal and a backend install
report none. Scopes both to artifact-backed gallery models and leaves
the verb, the name and the percentage as what every operation shows. A
worker backend install reports its bytes through fields the operations
payload does not carry, so the distributed section now describes the
percentage and the node roll-up, with per-file counts pointed at the
per-node detail.

Also: staging jobs carry no error, so they never reach Needs attention
and Retry never had a staging case to exclude; an install that involves
workers is no longer called node-scoped, which this page uses for
node-targeted installs; and the record timestamps carry nanoseconds.

* docs: state only the verb and the name as unconditional on the strip

The percentage is as conditional as the bytes were: it renders only for
a running operation that has reported progress, so a queued operation, a
failed one and a removal never carry it. A removal in particular sits at
progress zero for its whole visible life, since the delete path reports
none and its completion is filtered out. Both the strip and the card
paragraphs now lead with what always shows and list the rest as
conditions.

The Cluster chip matches on a node list that finished operations do not
carry, so a fan-out install leaves the chip once it reaches the record.
Scoped that claim to the live sections.

Two more of the same shape, found by re-reading each clause alone: the
strip also appears for a failure, which is not running, and the
four-second hold only applies when nothing replaces the operation that
just finished.

* fix(ui): stop reporting a cancelled install as installed, and make queued real

Three defects that all trace to one root cause: `isCancelled: true` is
unreachable from /api/operations. Every writer of Cancelled=true also sets
Processed=true, the handler skips Processed && Cancelled, and OpCache.GetStatus
evicts a cancelled op before the handler iterates it.

Cancelling the last running operation put a green "Installed model X" on the
strip for four seconds: the completion hold was guarded by
`!previous.isCancelled`, which is dead. A cancellation deletes the operation
server side, so the strip sees exactly what it sees on a completion, and
nothing in the payload separates the two. The signal now comes from the side
that issued the cancel: the operations context remembers the job IDs it
cancelled (pruned after a minute) and the strip asks before it holds anything.
A cancelled operation goes as soon as it stops; the record already reports it
as cancelled.

isQueued was set only when the gallery status was missing, but markQueued
publishes a "queued" status at admission, so a queued op has a status for its
whole queued life and the state was unreachable outside a microsecond window.
Every operation waiting behind a running install rendered as "Installing model
X" with a spinner. The queued phase is now the signal, via an exported
PhaseQueued and a nil-safe OpStatus.IsQueued() next to the writer.

With those two fixed, the Cancelling state has no way to be entered: cancelling
is instantaneous from the API's point of view. Its branches, CSS, locale key
and the isCancelled field itself are removed rather than left for a future
reader to assume they work.

* fix(ui): keep a removal a removal, and say what an install is doing

OpStatus.Deletion was set once, at admission, and lost on the next status
write: UpdateStatus replaces the whole status and only carried Nodes
forward. Every later writer (the worker's first write, the progress
ticks, the failure path) leaves the field at its zero value, so the flag
survived only the queued window, and both surfaces test isQueued first.

The reachable consequence is that a failed removal reported itself as a
failed install, which is exactly the shape the Activity page offers Retry
for, and Retry installs: pressing it on a removal that failed
re-downloaded the model. A running delete also rendered as "Installing
model X" with a spinner, and a successful one as "Installed model X".

Carry Deletion forward the way Nodes already is. A job is a delete or an
install for its whole life; an unset flag means "no new information", not
"this is an install". Pinned by Go specs on both the service and
/api/operations: the existing Playwright specs were green only because
they stubbed a payload the server could not emit.

Also restore the operation's own status message on the Activity card.
Phases and byte counters exist only on the managed-artifact path, so a
legacy files: gallery model and every backend install rendered a sub-row
with nothing in it but the verb. The strip stays terse on purpose.

And give the strip's name a min-width floor: overflow: hidden zeroes its
automatic minimum, so a long error squeezed the name down to "mod…" and
the identity of the thing that broke was the first thing lost.

primaryOperation is made module-private: its comment claimed the Activity
page selected the same operation, but that page shows all of them,
partitioned into failed and running, and never imported it.

* feat(activity): read the operations record from PostgreSQL

The Activity page's record of finished installs and removals was a 50-entry
in-memory ring per frontend replica. In distributed mode that is the wrong
place for it: each replica keeps its own copy, a replica added by a scale-out
or a rolling deploy starts empty and never backfills, and "Clear history"
clears only the replica that served the request, so the record reappears on
the next poll routed elsewhere.

The data is already in gallery_operations. Read it from there.

GalleryStore gains ListTerminal and ClearTerminal, sharing a lifted
terminalStatuses set with CleanOld so there is one definition of "finished".
ListTerminal orders by updated_at, when the operation reached its terminal
status, because the record reports what finished and when.

OpCache.History and ClearHistory dispatch on whether a store is wired, so the
HTTP handlers and the OpRecord JSON shape are unchanged and the page needed no
change. A failed store read falls back to the local ring rather than blanking
the page, and ClearHistory empties the ring as well so a database blip cannot
resurrect a record the admin just cleared.

The name derivation in recordTerminal is lifted into operationDisplayName and
used by both paths, so the ring and the store cannot name the same operation
differently.

Also fixes a pre-existing bug the store path made visible: the backend channel
hardcoded op_type "backend_install" even for a removal, while the model channel
derives model_install/model_delete from op.Delete. Both channels carry the same
ManagementOp, whose Delete field the backend handler already branches on, so
the backend channel now derives backend_delete the same way.

* fix(activity): keep a cancelled operation cancelled, and report a failed clear

Review follow-up on the store-backed Activity record.

A cancelled install was recorded as a failure. The cancel handler persists
"cancelled" synchronously, then the handler goroutine unwinds with the context
error and Start hands that to updateError unconditionally, which overwrote the
row with "failed: context canceled". The page rendered a cancelled install as a
red failure card offering Retry, with a raw context error as the reason.

Fixed in GalleryStore rather than in Start, because an operation finishes once
and the paths that retire one are not mutually exclusive: UpdateStatus now
refuses to rewrite a row that already reached a terminal status. That also pins
updated_at to when the operation really finished, which is the key the record is
ordered by, and Create's upsert now freezes the same columns so a worker
dequeuing an operation the admin cancelled while it was queued cannot reopen it
as pending.

ClearHistory returned nothing, so a failed delete logged a warning while the
handler still answered 200. The admin watched the record clear and come back on
the next fetch with nothing said about why. It now returns the error, the DELETE
handler answers 500, and the store is cleared before the local ring so a failure
leaves the fallback record intact rather than faking an empty one.

Hydrate is the only reader that decides from op_type whether an operation is a
removal, and it tested for "model_delete" exactly, so the backend_delete added
in the previous commit hydrated as an install: a replica restarting during a
backend removal rendered "Installing backend X". Both discriminations now go
through IsDeleteOpType/IsBackendOpType so a fifth op_type cannot silently read
as an install in whichever consumer was missed.

Also: the backend channel now persists Cancellable as !op.Delete, matching the
model channel; IsBackend falls back to the op_type prefix, since is_backend_op
is only written by UpsertCacheKey and the rows needing the name fallback were
reporting backend operations as models; and an unrecognized terminal status is
logged rather than quietly filed as a success, which is what the comment already
claimed.

* fix(activity): keep a reaped operation correctable by its real outcome

The terminal-status freeze added in the previous commit was too wide. It froze
"failed" alongside "completed" and "cancelled", and the stale reaper writes
"failed" onto operations that are still going to run.

The gallery worker is a single goroutine consuming both channels serially, so
an operation queued behind a large download sits in "pending" with nothing
bumping updated_at, and ReapStaleOperations gives up on it after 30 minutes.
That used to be self-healing: the worker dequeued it, Create reset the row to
"pending", and the operation reported its real outcome. With the freeze the row
stayed "failed" forever while the install ran and succeeded underneath it: a red
failure card offering Retry for a model that is installed, omitted from
ListActive so no replica hydrates it, and no longer deduped cluster-wide by
FindDuplicate.

Freeze on ("completed", "cancelled") instead. That is all the cancelled-install
fix ever needed, and it leaves a failure correctable by what actually happened.
The set is separate from terminalStatuses, which ListTerminal, ClearTerminal and
CleanOld all still want in full, because the two mean different things: a
failure can be superseded by a real outcome, a completion or a cancellation is
the real outcome.

UpdateStatus now writes the error column unconditionally, so a corrected
outcome drops the previous attempt's reason rather than being recorded as
completed while still carrying "stale operation reaped" as its error.

Also adds the route-level spec for the 500 branch of DELETE
/api/operations/history, and trims a comment that credited the persisted
cancellable column with more than it survives long enough to do.

* fix(activity): offer Cancel in the phase that can honour it

The cancellable flag was set at both ends of an operation's life and was wrong
at both, in opposite directions.

A queued operation is cancellable whatever it is. EnqueueModelOp and
EnqueueBackendOp select on the operation context, so cancelling one that is
still waiting releases the delivery goroutine and abandonQueued retires it: the
worker never sees it, nothing is downloaded, nothing is deleted. markQueued
nevertheless wrote Cancellable: !deletion, so a queued removal reported
cancellable: false and the UI hid the Cancel button in the one window where
pressing it both works and leaves no trace. A removal queued behind a large
install was stuck there until the install finished.

A running removal is not cancellable at all. DeleteModel and DeleteBackend take
no context, and modelHandler only checks the operation context after the call
returns, so a "cancelled" verdict would land after the model was already gone.
Both handlers nevertheless wrote Cancellable: true unconditionally at entry,
ahead of the op.Delete branch, offering a Cancel button the server cannot
honour.

So the queued phase is more cancellable than the running phase, which is the
reverse of the usual shape. markQueued now reports true unconditionally, and
the handler-entry writes report !op.Delete. Both sites carry a comment saying
why, because reading either one alone suggests the other is a bug.

GalleryStore.Create keeps !op.Delete: it runs at dequeue, so its value already
describes the running phase. Its comment now says so.

Specs cover queued removal, queued install, running removal and running install
through the handlers, plus the queued-removal case through /api/operations
where the flag is consumed, plus the behaviour the whole asymmetry rests on: a
removal cancelled while queued never reaches the worker and deletes nothing.
No existing spec asserted the old values.

* fix(activity): clamp the installer message, and add a real-binary e2e spec

Running the page against a real local-ai showed the legacy installer message
wrapping to three lines and dominating the card: it embeds an absolute file
path, so it is both long and a single unbreakable token. One line, ellipsised,
full text in the title, matching what the error string already does.

The spec that found it runs with no route stubbing at all. Every other spec
here stubs /api/operations, which is how a payload the server cannot emit
(isDeletion true on a live operation) stayed green through a full review while
the UI rendered a removal as an install. It is skipped unless
LOCALAI_REAL_BINARY is set, so CI is unaffected.

mudler's LocalAI [bot]andEttore Di Giacinto 6584db992f fix(nodes): never schedule a model onto a node that cannot store it (#11054)
* fix(nodes): never schedule a model onto a node that cannot store it

A worker whose models filesystem was 100% full kept advertising
`status: healthy`, stayed a scheduling candidate, was picked to host a
70 GB video model, accepted the staging request, transferred ~17 GB and
only then failed:

  staging .../whisper-large-v3/model.fp32-00001-of-00002.safetensors:
    upload to node b7bacbf4-... failed with status 500:
    writing file: /models/longcat-video-avatar-1.5/...: no space left on device

The node was at 937G/937G/0-avail. Total elapsed before the truth
surfaced: 16 minutes, for a decision that could never have succeeded.

The worker health signal only ever proved liveness. `/readyz`
(WorkerReadiness/NATSReadiness) checks the NATS link; `status: healthy`
in the registry is driven by heartbeat recency. Node capacity carried
VRAM and RAM but no disk figure at all, and the router compared model
size against VRAM only — nothing anywhere looked at free space on the
filesystem that staging actually writes to.

Report it, then use it:

- Workers now measure the filesystem backing their MODELS directory
  (not `/` -- staged weights land in the models path, and that mount is
  very often separate) and report `total_disk`/`available_disk` on
  registration and on every heartbeat. Free disk moves faster than VRAM
  under staging traffic, so the per-heartbeat refresh matters.
- The SmartRouter drops nodes that cannot store the model before it
  picks one. The requirement comes from `modelPayloadBytes` -- the same
  local paths `stageModelFiles` uploads, already computed for the
  size-derived load budget -- plus a 5% / 1 GiB margin, rather than a
  fixed percentage of the node's disk. A percentage threshold would take
  a small-but-usable node out of rotation for models it could hold, and
  on a homogeneous cluster would strand every node at once.
- When no node fits, scheduling fails immediately with an error naming
  the requirement and each node's free space, instead of picking one and
  discovering it mid-transfer.

Two deliberate non-changes. Low disk does not mark a node `unhealthy`:
the check is per model, so a node too small for one model stays a valid
target for smaller ones. And `total_disk == 0` means "does not report
disk" (pre-upgrade worker, or a failed stat), not "full" -- such nodes
pass through untouched so a rolling upgrade never empties the candidate
pool. A genuinely full node is distinguishable: non-zero total, zero
available. Registry read failures are logged and scheduling continues
unfiltered; a database hiccup must not wedge a cluster.

Free space is surfaced on the node detail page next to VRAM, since the
incident's signature was a node that looked entirely healthy.

* feat(nodes): make the disk-headroom check operator-controllable

The admission check added in the previous commit had no off switch. A
scheduler-side veto with no escape hatch is a liability: our size
estimate can be wrong (deduplicating or compressing filesystems, a
backend that fetches its own weights rather than loading the staged
copy), and an operator who hits that has no way out but a downgrade.

Add one knob with two surfaces that share a single source of truth:

- `--distributed-disk-headroom-check` / `LOCALAI_DISTRIBUTED_DISK_HEADROOM_CHECK`
  (default true), following the `--distributed-prefix-cache` pattern for
  a default-on distributed feature.
- `distributed_disk_headroom_check` in the runtime-settings registry, so
  it can be flipped without a restart from `POST /api/settings` and from
  Settings -> Distributed in the WebUI.

Both write `DistributedConfig.DiskHeadroomDisabled`, and the SmartRouter
reads that member LIVE on every scheduling decision through a closure
over the application config rather than a value snapshotted at
construction. Env/CLI sets the boot value, the runtime setting overrides
it live, last write wins, and there is exactly one member to read.
Snapshotting would have made the runtime toggle a no-op until restart.

Disabled means WARN, not SKIP. Selection goes back to ignoring free disk
-- byte for byte the pre-check behaviour -- but the check still runs, and
when it would have rejected every node it says so, naming the knob that
suppressed it. Going quiet when switched off would reproduce the exact
condition that made the original incident expensive: a cluster doing
something that could not work and saying nothing. Disabling is also
logged once at startup. Warning only on the total-rejection case keeps
it actionable rather than chatty on a heterogeneous cluster.

Also fixes a false positive in the check itself: shared-models mode
(LOCALAI_DISTRIBUTED_SHARED_MODELS) stages nothing at all -- every node
already mounts this models directory at this path -- so demanding the
full checkpoint size of free space per node would have rejected a
cluster that needs no new bytes. The check is skipped there entirely.

Candidate is one option in a meta entry's ordered variant list. It names a

EffectiveMinVRAM resolves the VRAM floor, letting an authored min_vram win
over a nightly-inferred one. An unparseable floor errors instead of being
treated as absent: swallowing a typo would turn a constrained candidate into

* fix(gallery): key meta pin recall on the installed name and detach resolved entries

Six review findings on the meta-entry install path.

Pin recall was keyed on the gallery entry name while applyModel writes the
record under the install name (req.Name when supplied), so a meta installed
under a custom name with a pin lost that pin on reinstall and was silently
re-resolved onto a different variant, possibly swapping its backend. Compute
the install name with applyModel's own precedence before the recall.

ResolveMetaModel returned a shallow struct copy, so the resolved entry's
Overrides aliased the gallery entry's map and the install path's in-place
mergo merge wrote the caller's request into the shared catalog. Detach
Overrides, ConfigFile, AdditionalFiles, URLs and Tags. Not exploitable today
only because this path re-unmarshals the gallery per call, which is a
property nobody should have to rely on.

Also: overlay the meta's name onto the persisted config for meta installs so
the gallery file no longer records the variant's name; move the pinned-VRAM
warning below the variant validation so a pin naming a nonexistent entry does
not warn about VRAM before failing for an unrelated reason; and stop seeding
config.URLs in the config_file branch, which duplicated every declared URL.

Add seven network-free specs driving InstallModelFromGallery with a meta
entry: variant payload wins over the meta's legacy url fallback, the
resolution record round-trips to disk, a pin is recorded and honored on
reinstall including under a custom install name, and the resolved entry does
not alias the gallery's maps.

* fix(gallery): deep-copy meta overrides and make two specs functional

ResolveMetaModel detached the resolved entry's Overrides and ConfigFile with
maps.Clone, which only copies the top level. Gallery overrides are nested in
practice (parameters.model is near-universal) and the install path merges the
caller's request with mergo.WithOverride, which recurses into nested maps and
overwrites them in place, so the gallery entry's own inner maps were still
reachable and still got rewritten by the last caller to install.

Copy both maps all the way down instead, recursing through the container shapes
a YAML decoder produces. ConfigFile is not mutated on the install path today,
but it carries the same kind of nested payload and leaving it shallowly cloned
would invite the bug back.

Also fix two specs that passed whether or not their target fix was present:

- "does not write the caller's overrides back into the gallery entry" re-read
  the catalog from disk, which re-unmarshals fresh structs and so cannot
  observe in-memory aliasing. It now asserts against the in-memory gallery
  entry and drives the real mergo merge.
- "round-trips the resolution record to disk under the meta's name" asserted a
  name that is already correct in the config_file branch. It now drives the url
  branch via a file:// fixture, where the meta-name overlay actually applies.

Both were verified red by reverting their fix.

* test(gallery): lint meta model entry invariants in index.yaml

Adds Ginkgo specs that parse the shipped gallery/index.yaml and enforce
the invariants that keep meta entries safe: a legacy url fallback equal
to the final candidate's url, references only to existing non-meta
entries, a min_vram floor on every candidate but the last-resort one,
a capability drawn only from the vocabulary the system can report, and
descending VRAM floors within a capability group.

The capability check is the only compensating control for a typo there.
Candidate matching is a case-sensitive exact comparison against
SystemState.DetectedCapability(), so an unknown value never matches and
falls through silently instead of erroring. The vocabulary therefore
mirrors the raw return set of getSystemCapabilities(), which notably
excludes "cpu": that is a fallback key inside Capability(capMap) on the
meta backend path, never a reported capability. A CPU-only host reports
"default".

These pass vacuously until the pilot meta entry lands; the guard is
intentionally in place before the thing it guards.

* test(gallery): close coverage gaps in the meta entry lint

The ordering invariant grouped candidates by capability and asserted floors
descend within a group. A candidate with an EMPTY capability matches every
host, so it does not belong in its own group: it dominates every later
candidate whose floor is at or above its own, across capability groups.
Track a running minimum floor over the unconditional candidates instead,
which subsumes the old same-group check for the empty capability.

Every spec skipped non-meta entries, so with zero meta entries in the index
all five bodies were no-ops. Aligning GalleryModel.IsMeta() with
GalleryBackend.IsMeta(), whose semantics are deliberately opposite, would
have made all of them pass while checking nothing. Extract each invariant
into a helper over a slice of entries returning the violations it finds, and
cover those helpers with synthetic fixtures so the logic stays tested at zero
meta entries. The index-driven specs are now a thin application of already
proven logic.

Also assert the index parses non-empty, report every violation in one run
rather than aborting on the first, and parse the index once for the suite.

* ci(gallery): add nightly denormalization of meta model candidates

Fills the read-only backend, quantization and inferred_min_vram fields on
meta gallery candidates and opens a PR, modeled on the existing
checksum_checker job. Computing these needs network access, so it happens
nightly rather than at install time.

An authored min_vram is never modified: a human who measured a real load
knows more than a pre-download estimate does.

The index is rewritten via yaml.Node rather than a document round-trip. A
full round-trip reflows all ~26k lines of gallery/index.yaml, which would
bury the computed values and make the nightly PR unreviewable. The rewrite
touches only the three derived keys, so authored styling survives and a run
that computes nothing leaves the file untouched.

* fix(ci): keep the gallery denormalize diff reviewable and self-healing

The nightly denormalization job edits YAML nodes instead of round-tripping
structs so its PR stays small enough for a human to review, but the write
path undid that: yaml.Marshal re-encoded the node tree at yaml.v3's default
4-space indent and dropped the leading document marker, reflowing roughly
6000 lines around the handful of real changes. Encode through
yaml.NewEncoder at the index's authored 2-space indent and restore the
header. A write that changes three fields now changes three lines.

Stale inferred_min_vram values were also never cleared. Both skip paths
(an authored min_vram is present, or the candidate is the last resort)
returned before touching the field, so a candidate that gained a floor or
became the last resort after a reorder kept an inferred value that
EffectiveMinVRAM reported as a real constraint, failing the meta lint with
no way for the job to self-heal. Clear the field before both skips.

The workflow discarded a whole night's work on any single failure: the
program exits 1 when a candidate cannot be estimated, which aborted the job
before the PR step, so one unreachable candidate blocked every other
refresh indefinitely. Capture the status, open the PR with what was
computed, mark the PR body as partial, and fail the run afterwards so the
problem still surfaces.

Also preserve the index's existing file mode instead of forcing 0644, and
drop the redundant //go:build ignore tag, since Go already skips dot
directories and the sibling modelslist.go carries no tag.

* feat(gallery): add nanbeige4.1-3b meta entry with hardware-resolved variants

Adds the first real meta entry to the gallery index. It resolves to the
Q8_0 build on hosts with at least 6GiB of VRAM and to the Q4_K_M build
everywhere else, installing either payload under the stable name
nanbeige4.1-3b.

The entry carries a url equal to its final candidate's url. LocalAI
releases that predate candidates support parse the index non-strictly
and drop the key silently, so without that url they would list the entry
and install nothing. A regression spec parses the index the way those
releases do and asserts every meta entry stays installable for them.

Also teaches core/schema/gallery-model.schema.json about candidates. The
schema sets additionalProperties: false at the top level, so an author
following CONTRIBUTING.md and adding the yaml-language-server comment
would otherwise get a validation error on this entry.

* feat(gallery): make candidate entries complete, installable entries

Reworks hardware-resolved gallery variants after a design pivot. There is no
longer a separate "meta" entry kind. A gallery entry is a normal, complete
entry that may additionally carry candidates:, a list of hardware-gated
upgrades over itself, and the entry is itself the last-resort candidate.

The previous design relied on a bare url: as the fallback for LocalAI releases
that predate candidates support. That fallback is empty in practice: none of
the 80 gallery/*.yaml files carry a top-level files:, and 1216 of 1281 index
entries carry their payload in the index entry itself, so a url alone yields a
config template with nothing to download. Since every released LocalAI reads
gallery/index.yaml live from master, merging a payload-less entry would have
shown every existing user a model that installs to a broken state. Making the
entry its own base candidate removes the problem at the root: old clients drop
the candidates key and install the entry exactly as they do today.

Resolution order is now explicit pin, then capability plus VRAM over the
declared upgrades, then the entry itself. The entry ALWAYS installs: when its
own min_vram or capability is unmet the installer warns and installs it
anyway, because there is nothing below it and refusing would make the gallery
behave worse the newer the client is. A pin naming the entry's own name is
valid and is how an operator declines an upgrade.

IsMeta() becomes HasCandidates(), ResolveMetaModel becomes ResolveVariant, and
the persisted meta_name record key becomes entry_name. GalleryBackend.IsMeta()
is a separate concept and is untouched.

The lint drops the three rules the pivot makes wrong (url equality with the
final candidate, no inline payload, unconstrained final candidate) and gains
one: the entry's own floor must sit strictly below every candidate's, since a
base that outranks a candidate makes that candidate unreachable.

The pilot entry is now the existing nanbeige4.1-3b-q4, which gains a 2GiB
floor of its own and a single 6GiB upgrade to nanbeige4.1-3b-q8, replacing the
separate nanbeige4.1-3b entry added in d0d441bb4.

* feat(gallery): select model variants by hardware fit, not authored order

Gallery entries could already carry a list of alternatives, but selection was
an authored, ordered, first-match policy: every candidate declared a
`capability` string and the VRAM floors had to descend in a hand-tuned order.
That pushed hardware knowledge onto whoever edits the gallery and made ordering
load-bearing, so a reordered list silently changed what users installed.

None of it was necessary. SystemState.IsBackendCompatible already derives
hardware support from a backend name alone: it knows MLX and metal are
Darwin-only, CUDA is NVIDIA-only, ROCm AMD-only, SYCL Intel-only. Selection can
read that instead of asking authors to restate it.

Authoring is now just a list of names:

    - name: qwen3.6-27b
      min_memory: 4GiB
      variants:
        - model: qwen3.6-27b-mlx-8bit
        - model: qwen3.6-27b-gguf-q8
          min_memory: 28GiB

and all the intelligence moved into the selector. Given a host it drops the
variants whose backend cannot run here, drops those whose known memory
requirement exceeds what the host has, and takes the LARGEST of what is left,
because a bigger footprint is a higher quality quantization of the same model.
A variant of unknown size is kept, since nothing proves it does not fit, but it
ranks last so a proven fit always beats a guess. An explicit pin still wins
outright, and if nothing survives the entry installs its own payload: the base
always installs, this never refuses.

Available memory is VRAM when a GPU was detected and system RAM otherwise, read
through xsysinfo so a cgroup limit is honored and a container gets its own
limit rather than the node's RAM.

Capability disappears entirely, from the types, the schema and the lint. VRAM
and RAM collapse into one `min_memory`, because a model's footprint is roughly
the same wherever it lives and one figure is compared against whichever applies.
The lint rules about ordering, the capability vocabulary and floor
relationships are deleted with the hazards they described; what remains is that
every variant names an entry that exists and does not itself declare variants,
plus that any memory figure actually parses.

* gallery: size model variants with a live probe, drop the nightly denormalizer

Selection needs each variant's size to decide whether it fits and to rank
largest-first. That figure was written into the index by a nightly job, which
made the gallery carry a derived value that could drift from the entry it was
derived from. Derive it at install time instead.

pkg/vram already sizes a model without downloading it, and the gallery UI
already uses it: a remote GGUF header range-fetch, then an HTTP HEAD for the
content length, then any declared size:. It caches its results, so reuse it
rather than writing a second probing path.

A probe failure must never fail an install, so an unprobeable variant is
treated as unknown: it survives the memory filter, because nothing proves it
does not fit, and it ranks last, so a known-good fit always beats a guess. If
every probe fails, selection still terminates on the base entry.

The probe is injected through ResolveEnv rather than called directly, for the
same reason the backend compatibility check is: specs pin an exact size, or an
exact failure, without reaching the network.

With that in place three things are dead weight and go:

- The nightly job and the fields it populated. Variant.Backend was redundant
  because the backend is resolved live from the referenced entry during
  selection, and Quantization was display-only that nothing read.
- min_memory on the base entry. The base always installs and its floor could
  only warn, so it could not change any outcome.
- The lint rules and schema entries for both.

min_memory on individual variants stays, as the override for when the probed
size is wrong. An authored figure now suppresses the probe entirely rather
than merely outranking it, so it costs no round trip.

* feat(gallery): expose model variants for selection over API, CLI and MCP

A gallery entry may carry `variants:`, alternative builds of the same model.
Selection already worked at install time, but nothing could see what an entry
offered or ask for a specific build, so the feature was undrivable.

Listing: `GET /api/models` now reports `variants` and `auto_variant` for the
entries that declare variants. Each variant carries its resolved backend, its
measured size and whether it fits this host. `auto_variant` is what installing
without a choice would pick right now.

The new gallery.DescribeVariants runs the same variantOptions + SelectVariant
pass the installer runs, so the reported default cannot drift from what
installing actually does, and HostResolveEnv is extracted so both derive the
host and share pkg/vram's probe cache from one place.

Performance: an entry that declares no variants returns early without touching
the probe, so the ~1280 ordinary entries cost exactly what they cost before.

Selection: `variant` is accepted on POST /models/apply, as a query param on
POST /api/models/install/:id, on the gallery apply file/string request, as
`local-ai models install --variant`, and as a parameter on the install_model
MCP tool (both the httpapi and inproc clients). Empty means auto-select.

An unknown variant name now fails the install naming what was requested. This
closes a real hole: an entry declaring no variants short-circuits before
selection runs, so a requested variant was previously dropped silently and the
install reported success.

startup.InstallModels ends in a variadic model list, so install options could
not be appended to it; InstallModelsWithOptions is added alongside and
InstallModels delegates to it. No caller signature changed.

* feat(gallery): drop the redundant variant min_memory field

Variant.MinMemory was an authored override for when the live probe misreads
a variant's footprint. It duplicated an existing field: probeEntryMemory
already passes the entry's declared size: into EstimateModelMultiContext,
whose cascade prefers that declared size over its own guesswork. Correcting
size: on the referenced entry fixes the figure for every consumer rather
than only for variant selection, so min_memory shadowed the right answer.

A variant is now nothing but a name. Its effective size is exactly the probe
result, and an unknown stays unknown: it survives the filter and ranks last.

EffectiveMemory loses its error return along with the field. The authored
string was the only thing that could fail to parse, so the error had no
remaining source and was propagating dead nil-checks through SelectVariant,
DescribeVariants and the pin warning.

Selection behaviour is unchanged. The specs covering probe-derived sizing,
ranking, filtering, the unknown-size path, pin recall, entry/variant
metadata split and deep-copy isolation all survive; the three install specs
that needed a definite size now declare it through the referenced entry's
own size:, which exercises the documented escape hatch directly.

gallery/index.yaml is untouched: no entry ever carried the key.

* fix(gallery): rank the entry's own build against its variants

Variant selection pulled the declaring entry's own payload, the base, out
of the candidate set and consulted it only once every declared variant had
been rejected. Two real failures followed.

A variant whose size the probe cannot determine deliberately survives the
memory filter, because nothing proves it does not fit. As the only survivor
it then won outright on any host, however small: a 2GiB machine installed an
unmeasured variant in preference to the 4GiB build the entry itself ships,
with no warning. 241 of the 1280 current index entries carry no files and no
size, which is exactly that shape.

"Largest wins" also broke whenever the base was the largest. An author
writing a Q8 entry that offers a Q4 downgrade for small hosts, a natural
shape that nothing in the lint, schema or docs discourages, had the Q4
installed on every large host instead.

Make the base an ordinary participant. It is still exempt from both filters,
so selection always terminates on something installable, but it is now
ranked against the variants: a proven fit first and largest, then the base,
then any variant whose size nothing could measure. Both failures disappear
together. The base is probed for its size accordingly, which it was not
before, because an unsized base would lose every contest to an unmeasurable
variant.

FellBackToBase is kept but narrowed to "no declared variant survived",
rather than "the base was chosen", since the base now also wins on merit and
that is not worth warning about.

A recalled variant pin also became a permanent install failure. A pin the
caller supplies on this request must stay fatal, but one recalled from
._gallery_<name>.yaml can be invalidated by any later gallery edit, and
failing on it turned one rename into a model that could never be reinstalled
or upgraded again short of deleting a dotfile the user has never heard of.
A stale recalled pin is now dropped with a warning naming it, and selection
runs as if it had never been recorded.

Also drop the last textual reference to two abandoned designs from the
DetectedCapability comment, correct the documented variants JSON example,
which showed a memory_bytes of 0 that omitempty makes impossible, and remove
an em dash from the install skill.

* fix(gallery): budget variant memory from RAM when a GPU reports no VRAM

Variant selection read its memory budget from VRAM whenever a GPU
capability was detected, and from system RAM only when none was. Apple
Silicon satisfies the first branch and fails the premise: arm64 macs report
the metal capability unconditionally, without probing anything, while
TotalAvailableVRAM has no discrete VRAM pool to find and returns zero. The
budget therefore came out as zero on every Mac.

Zero drops every variant carrying a known size, so the base build was
installed on all of them however much memory the machine had. The feature
was inert on the platform, and silently: falling back to the base is a
legitimate outcome, so nothing looked wrong.

Take VRAM only when it is actually a number, and fall back to RAM
otherwise. On a unified-memory host RAM is not an approximation of the
budget, it is the budget, since the GPU shares it. A discrete GPU whose
VRAM could not be read also lands on RAM, which overstates what the card
holds but understates nothing the host has; the previous zero understated
both.

An unreadable RAM figure still yields zero and still installs the base, so
a genuinely unknown host is not talked into a larger download.

This is what turned tests-apple red: "installs a fitting variant's payload
under the entry's own name" asserts on selection, and the runner resolved
to the base because its budget was zero. The added specs pin the branch
directly rather than relying on a macOS runner to notice again.

* feat(ui): add a model variant picker to the models gallery

PR #10943 shipped the server side: a gallery entry may declare `variants:`,
`GET /api/models` attaches `variants` and `auto_variant` to declaring
entries, and `POST /api/models/install/:id` accepts a `variant` query
parameter. Nothing in the UI consumed any of it, so the feature was not
reachable from the browser. This wires it up.

modelsApi.install takes an optional second argument and appends an encoded
`?variant=` only when one is given, so every existing call site keeps
sending exactly the request it sent before.

On the models table, an entry that declares variants gets a split button.
The primary Install still installs the auto-selected build, because auto is
the default and the point of the feature; the chevron opens a menu for a
deliberate override. It follows the Backends.jsx precedent: one shared
Popover re-anchored per row, rendering .action-menu items, which brings
Escape, outside-click and focus return along with it. An entry that
declares no variants renders exactly as it did before.

A variant that does not fit is dimmed but stays selectable, since the server
honors an explicit choice with a warning rather than refusing it.

memory_bytes is omitempty on the wire, so an absent key means the size is
unknown and never zero. A single helper guards both the menu and the detail
row, because formatBytes would otherwise render a falsy value as "0 B",
which reads as "needs nothing".

The expanded detail row gains a Variants section listing each build's
backend, size, whether it fits, which is the entry's own build, and which
one auto-selection would pick, built from the existing DetailRow helper and
.badge classes.

Eight Playwright specs cover the picker, including that plain Install sends
no variant parameter and that choosing one sends it. One pre-existing
assertion was scoped with .first(): the Variants section legitimately adds
more llama-cpp badges to the detail row, which tripped strict mode.

UI line coverage 49.42% -> 49.36% against a 40.0 baseline and 0.8pp
tolerance; branch coverage rose 72.04% -> 72.66%.

* fix(gallery): describe model variants from a companion endpoint

Variant description probes each referenced entry's weight files over the
network: an HTTP HEAD plus a ranged GET, serial, five seconds per probe
with no aggregate deadline. Running it inline in GET /api/models made one
listing cost (entries x variants) round trips. The Manage page fetches
with items=9999, so at 200 declaring entries that is ~1000 serial probes,
minutes of a blocked handler and gigabytes of range traffic for a single
page load. Only one entry declares variants today, but the feature exists
so that many will.

Follow the precedent already set for VRAM estimates. The listing now
reports only has_variants, a length check on loaded metadata that touches
nothing, and GET /api/models/variants/:id returns the description for one
entry, mirroring estimate/:id in route shape, auth and error handling.
DescribeVariants itself is unchanged; only its caller moved.

The picker fetches lazily at the two points where a user asks to see
variants, opening the split-button menu and expanding the detail row, and
caches per entry for the page session. An entry declaring no variants
issues no request at all.

A spec counts real HTTP hits on the weight files, so it goes red if
description becomes reachable from the listing path again through any
caller.

* feat(ui): filter the model gallery to entries that declare variants

The gallery is heading towards showing parent entries and hiding the
individual builds they reference, so a user sees one row per model
rather than six quantizations of it.

Adoption is a single entry today, so defaulting to that would leave a
one-row gallery. This ships the migration-phase inverse instead: the
default is untouched, and a toggle narrows the list to only the entries
that declare variants. It previews the end state and changes nothing
until someone asks for it.

The filter is server-side, next to term/tag/backend/capability and above
the pagination arithmetic. The listing paginates at 9 items, so
narrowing on the client would leave totalPages and availableModels
describing the unfiltered set and hand the user empty pages. It selects
on HasVariants(), which reads already-loaded metadata, so it issues no
variant probes.

The parameter is named has_variants after the listing field it selects
on, and is compared against "true" like the other boolean query params
(all_users, save_checkpoint), so has_variants=false reads as absent.
With it omitted the response is byte-for-byte what it was before.

The control is the shared Toggle component, matching the fitsFilter
toggle already on this page: same wrapper class, same icon and label
shape, same localStorage persistence. Unlike fitsFilter it resets to
page 1 on change, which a server-side filter has to do.

Stacking the toggle with a tag or backend filter easily yields nothing
while one entry declares variants, so the empty state now names the
variants filter as the cause rather than leaving a user to conclude the
gallery is broken.

* fix(ui): render gallery model descriptions as Markdown

Gallery descriptions are Markdown, but the React UI dumped them raw, so a
model whose description opens with an ATX heading showed a literal
"# Qwen3.6-27B [](https://chat.qwen.ai)" in the list.

Full-description areas now render through renderMarkdown (marked +
DOMPurify), matching how Backends.jsx and the Manage detail panels already
handle the same content:

  - Models.jsx expanded detail row
  - VoiceLibrary.jsx voice detail header

The truncated one-line previews must not render block Markdown: a leading
"#" would become an <h1> and wreck the row height and rhythm. They get a new
stripMarkdown() helper instead, which reduces Markdown to a single line of
readable plain text. It is used for the cell text and for the title tooltip,
since a tooltip full of "[](url)" is no better than a cell full of it:

  - Models.jsx gallery table description cell
  - Manage.jsx model and backend resource-row descriptions

stripMarkdown walks marked's lexer output rather than running regexes over
the source, so what it strips is by construction what renderMarkdown would
have rendered, and it needs no new dependency. Output lands in JSX text
nodes, so React escapes it; no new dangerouslySetInnerHTML beyond the two
full-description sites, both of which run DOMPurify.

* fix(ui): strip Markdown from the backends table description cell

Commit b35d630cf fixed this for gallery models but left the Backends admin
page with the same asymmetry: its detail panel renders the description
through renderMarkdown, while the collapsed table row dumped the raw gallery
string into both the cell body and the title tooltip.

That is user-visible. 40 of the 949 entries in backend/index.yaml carry
Markdown - insightface uses inline code backticks, others use lists and
links - and backend descriptions also contain embedded newlines, so the
one-line cell showed literal syntax.

The cell now runs stripMarkdown over the description once and uses the
result for the text and the title, matching Models.jsx and the
ResourceRowDesc component in Manage.jsx. The '-' placeholder is preserved,
and now also fires when a description reduces to nothing after stripping.
The detail panel is untouched and no new dangerouslySetInnerHTML is
introduced: stripMarkdown output lands in a JSX text node, so React escapes
it.

Three Playwright specs cover it: a description with a heading, inline code
and a link renders as clean text with no literal syntax and no block
element in the cell, the title tooltip carries the same stripped text, and
a backend without a description still shows the placeholder.

* ui(models): polish the variant detail view and scope rendered Markdown

The gallery detail pane rendered every field through the same two-column
label/value row, including the description. Multi-paragraph prose in a value
cell ran eight rows tall at the top of the pane on a ~1200px measure, breaking
the grid's rhythm exactly where the eye enters. Move it into its own full-width
block above the table, capped at a 68ch measure, keeping the label.

Rendered Markdown had no scoped typography anywhere in the app, so a
description opening with `#` inherited the browser default 2em inside a 13px
surface while a `##` further down was indistinguishable from body text. Add a
reusable .markdown-body block mapping h1-h6, paragraphs, lists, links, code,
blockquotes, images and tables onto the existing type scale, and apply it to
every renderMarkdown() consumer: the models detail, the backends detail, both
Manage details and the voice library detail.

Rebalance the variants list so the name leads. Backend and size drop from
badge/secondary weight to muted metadata; the FITS badge goes entirely, since
it was true of nearly every row and so said nothing, while the variant that
does not fit keeps a warning badge and a dimmed name. AUTO-SELECTED stays
marked because it answers what a plain Install produces. Rows share the
parent's grid tracks via subgrid so name, backend, size and status line up
down the list instead of raggedly following name length.

Finally, make each variant row actionable. It looked like a list of choices
but was inert text, with per-variant install hidden behind the split-button
chevron elsewhere; each row is now a button onto the existing
handleInstall(modelId, variant) path, with hover, keyboard focus and a
disabled state while an install is in flight.

* feat(gallery): collapse the listing to one row per model

The listing supported has_variants=true, which narrowed to entries that
DECLARE variants. With adoption at three entries that showed three rows,
which is useless; it was always a placeholder.

Replace it with the view that is actually useful: the deduplicated
gallery. Show every entry installable in its own right and nothing twice,
which means the parents plus every entry nobody references, and hide only
the builds another entry already offers as a variant, since those are
reachable through their parent.

The parameter is renamed to collapse_variants accordingly: the filter is
no longer a predicate on a row's own metadata but a view over the whole
gallery. Default stays off, so the response with the parameter absent is
unchanged.

VariantReferencedIDs never reports an entry that declares variants of its
own, so parents are always visible. That guarantees every hidden entry
has a visible entry offering it, and no chain can strand a row. Variant
resolution already refuses to install such a reference, but the listing
has to stay coherent in the presence of a gallery that has one rather
than silently swallowing entries. Self-references and dangling references
hide nothing.

The referenced set is computed over the whole gallery rather than over
what the other filters left, so an entry is hidden because a parent
offers it and never because of what the user searched for. The pass is
over metadata already in memory: it resolves nothing over the network and
triggers no variant description or size probe, so the listing's zero-probe
contract still holds.

The UI toggle keeps its behaviour (persistence, page reset, clear
filters) and becomes "One row per model", which says what the user gets.
Its localStorage key moves too, since the stored value meant a different
filter.

* feat(ui): show the collapsed model listing by default

The gallery listing is what a user reaches for to answer "what can I
install". Answering that with several rows for the same model, one per
build, makes the reader do the deduplication the collapsed view already
does, so the collapsed view is the one to land on.

The UI now asks for collapse_variants=true unless the toggle says
otherwise. The server default is deliberately untouched: a request with
the parameter absent still returns the full listing, because other API
clients depend on that response and collapsing it under them would be a
breaking change. Opting out omits the parameter rather than sending
false, so it asks for exactly the listing everyone else gets.

The stored preference changes vocabulary from '1'/'0' to 'on'/'off'. The
previous build wrote it from an effect that runs on mount, so a stored
'0' recorded that the page had been opened rather than that anyone chose
the expanded view, and honouring it would pin every earlier visitor to a
default they never picked. Only the new vocabulary counts as a choice;
a legacy '1' meant the collapsed view and is what the new default gives
anyway, so no earlier deliberate choice is lost.

Collapsing being the default also changes what the empty state may say
about it. An opted-into filter can be named as the cause of an empty
result; a default cannot, so the filters keep the top line and the
collapsed view drops to a hint below it, shown only once filters are
narrowing the set. For the same reason "Clear filters" now restores the
collapsed default instead of switching it off, and the toggle alone no
longer counts as a filter worth offering to clear.

The label stays "One row per model": it describes the view the user is
looking at rather than an action, so it reads the same whether it is
opted into or out of.

* gallery: group alternative builds of the same weights under variants

Sweep the gallery for entries that are alternative builds of the same
weights (different quantization, precision, or runtime format) and declare
them as variants of a single parent row, so the listing offers one row per
model instead of one row per quantization and the installer picks the
largest build that this host can actually run.

41 families over 95 entries, turning 54 entries into variants.

The parent is the bare-named entry wherever one exists, so nothing changes
about what any existing entry installs. Ranking already selects the largest
fitting build regardless of which entry is nominally the parent, so the
parent only decides the pathological case where nothing fits. For the ten
families that have no bare-named entry, the smallest build is the parent,
since that is the one that has to install when nothing fits.

Grouping was verified against the actual model filenames rather than the
entry names alone. Different parameter sizes, languages, finetunes, and
products that merely share a name prefix are left as separate rows: the
qwen3.6 APEX and pi-tune finetunes, the DFlash and MTP speculative-decoding
pairings, English-only versus multilingual Whisper, the QAT versus non-QAT
Gemma 4 weights, and the abliterated FLUX build are all distinct models.

Six parents define YAML anchors that other entries pull in with a merge key,
which would have handed their variants to every merging child. For the two
depth-anything anchors that would have made fourteen unrelated entries
advertise the base model's builds as their own. All 26 merging children
therefore carry an explicit empty variants list, which overrides the merged
key and is equivalent to the key being absent.

* feat(gallery): rank model variants by host backend preference

Variant auto-selection filtered candidates by whether their backend can
run on the host, then ranked the survivors by size alone. The backend
never influenced the choice beyond that gate, so a Mac offered both an
MLX build and a llama.cpp build kept neither filtered and installed
whichever was larger, leaving the native accelerated runtime unused. The
same held for CUDA against CPU on NVIDIA and ROCm against Vulkan on AMD.

Rank by the host's backend preference between the fit tier and size: fit
stays a filter, preference decides among the builds the host can equally
hold, and size still separates builds on equally preferred runtimes.

The preference data stays in one declarative table in pkg/system, now
read by a prefix lookup instead of a switch, so adding a capability or
reordering one host's runtimes is a one-line edit and the gallery's
ranking code carries no per-backend branching. MLX joins the metal rule
ahead of metal itself, which is inert for the existing alias-resolution
consumer because no alias group holds a candidate named for mlx.

An unrecognised backend, an unrecognised capability and an absent
preference list all collapse to the previous size-only ordering rather
than erroring or dropping candidates.

* fix(gallery): rank variants by engine name, not backend build tag

Variant auto-selection ranked candidates with
SystemState.BackendPreferenceTokens, but that function and the variant
ranker speak different vocabularies.

BackendPreferenceTokens returns BUILD TAGS ("cuda", "rocm", "sycl",
"vulkan", "metal", "cpu"). It exists to match installed backend build
directory names like "llama-cpp-cuda-12" during alias resolution in
ListSystemBackends. Variant ranking instead matches a gallery entry's
`backend:` value, which is an ENGINE NAME: "llama-cpp", "vllm",
"vllm-omni", "sglang", "mlx" and the rest. No engine name in
gallery/index.yaml contains "cuda", "rocm", "sycl" or "vulkan".

preferenceRank matches by substring, so on an NVIDIA host the tokens
[cuda, vulkan, cpu] matched neither "llama-cpp" nor "vllm", every
candidate scored identically and size alone decided. The NVIDIA, AMD,
Intel, darwin-x86 and vulkan rules were all inert. Only metal appeared
to work, and only because the token "mlx" happens to equal an engine
name. The mismatch does not error, it silently deletes the feature.

Separate the two vocabularies. backendBuildTagPreferenceRules keeps the
build tags and its original output for every capability, including
metal, whose "mlx" token is removed again; its alias-resolution consumer
is byte-identical to before. engineNamePreferenceRules is new, holds
engine names, and is read by the new EnginePreferenceTokens, which
HostResolveEnv wires into the renamed ResolveEnv.EnginePreference. Both
tables sit adjacent under one block comment naming each vocabulary and
each consumer, and share one lookup helper so their semantics cannot
drift.

On NVIDIA the order is vLLM, then SGLang, then llama-cpp: vLLM is the
throughput engine and a model published with a vLLM build is published
that way because that build is the one worth running. AMD and Intel get
the same order, since rocm and intel builds of both serving engines
ship. Metal prefers mlx over llama-cpp. Vulkan prefers llama-cpp, the
only LLM engine with a Vulkan build. darwin-x86 and unknown
capabilities are deliberately absent rather than guessed at, degrading
to the size-only ordering that predates preference.

preferenceRank stays generic and names no engine and no capability, so
adding a runtime remains a one-line table edit.

Specs pin the NVIDIA and metal rules through the live table and the real
HostResolveEnv wiring, so emptying the engine table or wiring the build
tag source back in both go red. A regression table asserts
BackendPreferenceTokens' original output per capability, and mirrored
locks assert neither table carries the other's vocabulary.

* docs: record that variant selection ranks by engine before size

A gallery entry can now declare variants, and selection ranks the builds a
host can run by engine preference before size. Nothing told a contributor
adding a backend that engineNamePreferenceRules exists, so a new engine would
silently rank below every known one and lose to whatever build happened to be
larger on hosts where it should have won.

Document the step where a backend is added, warn against the sibling
backendBuildTagPreferenceRules table (build tags, not engine names: the wrong
table matches nothing, scores every candidate equally and disables the
preference without erroring), and index it from AGENTS.md.

Fix the authoring and user docs, which still claimed the largest surviving
build wins. An author grouping builds under one entry has to be able to
predict what a user gets, and size alone no longer decides it.

* fix(gallery): prefer llama.cpp over GPU serving engines on hosts with no GPU

engineNamePreferenceRules had no row for the "default" capability, which
getSystemCapabilities() returns both when no GPU is detected and when a GPU
is present but under the 4 GiB VRAM floor. A missing row yields an empty
preference list, which preferenceRank reads as "score everything equally",
collapsing variant selection to size alone.

That would be harmless if the hardware filter dropped GPU serving engines on
such a host, but it does not. IsBackendCompatible derives support from the
engine NAME, and "vllm" and "sglang" contain none of the darwin, cuda, rocm
or sycl tokens it keys on, so they fall through to its closing "return true".
A vLLM variant therefore survives on a CPU-only box and wins whenever its
build is the larger of the two on offer: the machine installs vLLM in
preference to llama.cpp.

darwin-x86 had the identical hole. It was documented as a deliberate omission
because nothing accelerates on an Intel Mac, which is true about acceleration
and wrong about consequence: with every engine tied, download size decides.

Add rows for both putting llama-cpp first. The GPU engines are enumerated
behind it rather than left unmatched: an unmatched engine already ranks below
every listed one, so llama.cpp would win either way, but unmatched engines
also tie with each other and let size decide among them. Naming them fixes
that order. MLX is left off the darwin-x86 row on purpose so it ranks last,
since IsBackendCompatible admits darwin-tokened engines on that capability
even though MLX needs Apple silicon.

Preference orders survivors and never filters, so a model published only as a
vLLM build is still installed on a host with no GPU; there is a spec for it.

Surveyed every other value getSystemCapabilities() can return. nvidia, amd,
intel and vulkan have rows; the l4t and cuda-refined values reach the nvidia
row by prefix; "apple" and "" cannot reach the vendor fallthrough because the
darwin and no-GPU branches return earlier. default and darwin-x86 were the
only live holes.

BackendPreferenceTokens and its build-tag table are untouched, and
preferenceRank stays generic, naming no engine and no capability.

* gallery: prefer speculative-decoding builds when they fit

Rank serving features between engine preference and size, so a host that can
hold a DFlash or MTP build of a model's weights installs it instead of the
plain build. Both answer faster for the same output, so whenever one survives
the filters there is no reason to take the plain build.

Precedence is now fit, then engine, then serving feature, then size. Engine
outranks the feature deliberately: a serving feature makes the right engine
faster, it does not make a wrong engine right, so a plain vLLM build still
beats a DFlash llama.cpp build on NVIDIA. Fit outranks both, and a drafter
pairing is strictly larger than the plain build, so the existing size filter
drops it on a host too small for it before this axis is consulted.

The order lives in a third preference table in pkg/system, alongside the build
tag and engine name tables. It is the odd one of the three: not keyed by
capability, because no hardware prefers a plain build over an equivalent
faster one, and matched against whole segments of a gallery ENTRY NAME rather
than as a substring of a backend value. Nothing on a gallery entry declares a
serving feature, and tags are not a usable substitute: gemma-4-e2b-it:sglang-mtp
carries an mtp tag while ornith-1.0-9b-mtp and qwen3.6-27b-nvfp4-mtp carry
none. Entry names are author-supplied free text, unlike the closed engine
vocabulary, so a short marker can turn up inside an unrelated word and whole
segment matching is what keeps smtp-assistant from ranking as an MTP build.
The block comment over the tables now documents all three together and states
what each is matched against; the ranking code names no feature, so adding one
stays a one-line edit to the table.

29c49203b rejected these entries as serving configurations rather than
alternative builds of the same weights. The definition is now "alternative ways
to serve the same model", which includes them, so regroup 14 entries under 12
parents. Judged by the files each entry points at: the qwen3.6, qwen3.5, qwen3
and deepseek pairings are the base GGUF plus a drafter, the gemma-4 QAT MTP
entries are the same QAT weights at a different quantization plus an MTP
drafter, and the two sglang MTP entries describe themselves as the same model
served with speculative decoding. Left separate: qwen3.6-27b-mtp-pi-tune, a
finetune with its own weights, and every entry whose base model LocalAI does
not ship as its own row, which is the whole Qwopus line plus gemmable-4-12b-mtp,
mimo-7b-mtp:sglang and qwen3.5-4b-dflash.

None of the twelve parents defines a YAML anchor, so no variants key can leak
through a merge key and no empty override was needed this time. The index was
edited by line insertion only.

* feat(gallery): make the mtp tag authoritative for serving-feature ranking

Variant auto-selection ranks survivors by fit, then engine, then serving
feature, then size. The serving-feature lookup read only whole alphanumeric
segments of a variant's entry name, because tags were inconsistent: every
dflash entry carried a dflash tag, but only 7 of 20 MTP entries carried an
mtp tag.

Tag the 13 untagged MTP entries, then teach the lookup to read tags as well
as names. A tag is now the authoritative signal and is compared whole and
case-insensitively, which is safe precisely because a tag is a deliberate
declaration rather than free text: there is no word-inside-a-word failure
mode, so the segment splitting the name half needs is unnecessary there.

The name check stays as a fallback rather than being replaced. Switching to
tags only would have regressed the six already-grouped entries on the day it
shipped, and would depend on tagging discipline that does not exist yet.

The lookup still names no feature, so adding one remains a one-line edit to
servingFeaturePreferenceTokens.

* feat(gallery): make a declared tag the sole serving-feature signal

Variant auto-selection ranks survivors by fit, then engine, then serving
feature, then size. The serving-feature lookup recognised a speculative build
by either a declared tag or a whole segment of its entry name. Drop the name
half: a tag is now the only signal.

A name is author-supplied free text and a naming convention is not a contract,
so reading a marker out of one infers a capability nobody declared. The gallery
already had the failure in it: the four NVFP4 entries name MTP-bearing weights
while setting no option that enables speculative decoding, and being live
variants they were winning the feature axis without answering any faster.

overrides.options was considered as the replacement and rejected. It carries
spec_type:draft-mtp / spec_type:draft-dflash, which is what actually turns the
feature on, but that spelling is llama.cpp's config vocabulary: ds4 spells the
same feature mtp_path and sglang spells it speculative_algorithm in a
referenced config. Keying a cross-backend ranking decision on one backend's
option syntax would rank the other backends' builds as plain. Options are the
curation-time check instead, and never reach the selection logic.

With no fallback left, tag correctness is load bearing, so audit every entry
against the rule "tagged when the entry configures that feature, in whatever
vocabulary its backend uses". Three entries configure MTP untagged and gain the
tag (hy3, glm-5.2, qwythos-9b-claude-mythos-5-1m, all spec_type:draft-mtp with
no marker in their names). Four carry the tag while configuring nothing and
lose it: qwen3.6-27b-nvfp4-mtp, qwen3.6-35b-a3b-nvfp4-mtp,
qwopus3.6-27b-coder-mtp-nvfp4 and qwopus3.6-27b-v2-mtp-nvfp4, whose only option
is use_jinja:true. The dflash side was checked independently rather than assumed
consistent: all five dflash entries declare spec_type:draft-dflash and all five
are tagged, so it needed no edits.

Four entries keep a tag that a literal spec_type-only reading would strip,
because they configure MTP through a different backend: deepseek-v4-flash-q2-mtp
via ds4's mtp_path/mtp_draft, and the three sglang entries via
speculative_algorithm in their referenced configs. Stripping those would
contradict the reason spec_type was rejected as the signal and would demote four
genuinely faster builds to plain.

The index was edited by line insertion and deletion only, never round-tripped
through a serializer. A resolved-tag diff across all 1272 named entries, taken
after merge keys are applied, shows exactly these 7 changing and no entry
gaining or losing a tag through an anchor.

The two specs that pinned the name fallback are inverted rather than deleted,
since a name silently promoting a build is the regression worth guarding. The
whole-token guard survives on the tag path, where smtp must still not match mtp.

* fix(gallery): make deepseek-v4-flash variant targets installable

Clicking install on deepseek-v4-flash failed with "invalid gallery model".
The parent entry is fine, but all four entries it was grouped with declared
neither url: nor config_file:, and applyModel needs one of the two to have
anything to build a config from. They carry urls: (plural), the informational
HuggingFace link list, which is a different field. None of the four was ever
independently installable, so grouping them routed a previously-working
install into a broken entry.

Give each the url: the parent already resolves through. virtual.yaml is a
no-op base, and applyModel passes overrides to InstallModel separately from
the fetched config, so backend: ds4, the parameters and the ssd/mtp options
all still land exactly as authored. This is the same pattern the parent and
many other GGUF entries in the index already use.

Add the lint rule that should have caught this. checkVariantReferences only
proved a target exists and is not itself a parent, which is structural
validity: an entry can exist, declare no variants, and still be
uninstallable. checkVariantTargetsInstallable mirrors applyModel's
precondition instead, and names the parent, the target and the missing
fields, because whoever hits it is reading a gallery entry and has no reason
to know applyModel exists.

The two index-driven resolution specs live in their own Ordered container:
an Ordered container stops at its first failure, so sharing one with the lint
rules let a lint breach skip them silently.

Nine further entries gallery-wide have the same defect and are unrelated to
variants, so they are broken installs that predate this branch. They are left
alone here rather than buried in a regression fix, and widening the rule to
cover every entry is deferred with them so the gate can ratchet up in one
step instead of needing a skip list.

* fix(gallery): install entries with no url or config_file on an empty base

applyModel had three branches: fetch a base config from url:, build one from
an inline config_file:, or fail with "invalid gallery model". An entry
declaring neither is now installed on an empty base config, with overrides:
and files: supplying everything.

This is what the ~345 entries pointing at gallery/virtual.yaml were already
getting. That stub is five lines carrying name, description and license.
description and license are overwritten from the gallery entry immediately
after the fetch, and the name never reaches disk because InstallModel prefers
the install name. Crucially applyModel passes model.Overrides to InstallModel
as a separate argument rather than merging it into the fetched config, so
nothing an author writes depends on that base existing. The fetch bought a
round trip to GitHub and nothing else.

That makes f4ef80173 the wrong fix, so it is unwound. The four url: lines it
added to the deepseek-v4-flash variants are reverted: they are a pointless
network fetch now, and the family installs without them.

Relaxing the branch would hide a real authoring mistake, so a payload rule
replaces the base-config rule. An entry with no url, no config_file, no
overrides and no files installs nothing and would leave an empty model
directory while reporting success, so it is refused by name. The caller's
request counts toward the payload, because its overrides and files are merged
into the install exactly as the entry's own are. urls: (plural) is the
informational link list and does not count, which is what the four entries
that shipped broken had and why they were still uninstallable.

checkVariantTargetsInstallable asserted every variant target declares a url:
or a config_file:, which is no longer true and would now reject correct
authoring. checkEntriesInstallSomething pins what survives instead, and covers
every entry rather than only variant targets: the hazard is a half-written
stanza and a parent can be one as easily as a target. The old rule was scoped
to targets precisely because nine unrelated entries would have failed a
gallery-wide version; those nine are valid now, so the deferred ratchet
happens here in one step. 1280 entries, zero violations.

Those nine (aurore-reveil_koto-small-7b-it, lfm2-1.2b, the six liquidai_lfm2
entries and deepseek-v4-pro-q2-ssd) become installable for free. Each carries
overrides: and files:, and one of them is driven through the real install path
in a spec.

The no-fetch spec is paired rather than bare: an assertion that nothing was
fetched proves nothing unless something could have been, so a control runs the
same fixture with a url: pointing at a base config that is not there and
asserts the install fails. Only then does the identical fixture without the
url passing mean the read was skipped.

Follow-up, deliberately not here: the ~345 entries still naming virtual.yaml
can drop their url:. That is 345 index edits with their own risk, and mixing
them in would bury this change.

* ui(models): let search bypass the variant collapse, drop the toggle

The models page collapsed the gallery to one row per model by default and
offered a toggle to see every individual build. Because the collapse composed
with the search term, a build another entry offers as a variant could not be
found by typing its name, so the toggle was the only way to reach those builds
in the UI. A user who typed a name they knew existed got "no models found",
which reads as "that model does not exist".

Collapse is for browsing; search is for finding. An explicit search term now
bypasses the collapse in the listing handler, so a name lookup returns matching
entries whether or not a parent offers them. The term is trimmed once at the
top of the handler, so whitespace is neither a search nor a bypass; previously
an untrimmed blank term also narrowed the listing to whatever contained a
space. Tag and backend deliberately do not bypass: they refine a listing the
user is still reading rather than name an entry already known to exist.

That makes the toggle redundant, so it goes, along with its i18n strings in all
six locales, its localStorage persistence, its participation in "Clear filters"
and the empty-state hint telling users to turn it off. The hint was doubly
stale: it pointed at a control that no longer exists, and it was untrue exactly
when a user has a search term, since searching now sees every build. The page
always requests the collapsed listing.

The stored preference key is left inert rather than cleaned up: nothing reads
it, so a user who had the toggle off simply gets the collapsed view.

collapse_variants stays on the API, off by default, because other clients want
either view and the UI dropping its control is no reason to remove a working
parameter.

* feat(ui): give the models gallery filter form a deliberate structure

The filter area had accreted controls into one undifferentiated flow. The
"Fits in GPU" toggle and the backend select were direct children of
.filter-bar, the same wrapping container as the 18 taxonomy chips, so their
position was decided by how many chips happened to wrap at the current width
rather than by any layout intent. At narrow widths they were pushed past the
right edge of that container's horizontal scroll and became unreachable
entirely.

Restructure into three bands inside the house .filter-bar-group wrapper that
components/FilterBar.jsx already uses on Backends and the System tabs:

  1. query scope: search plus the backend select
  2. taxonomy: the chip row, alone, free to wrap
  3. refinements: fits-in-GPU and context size, under a hairline rule

The backend select leads the chips rather than trailing them because picking a
backend disables the use cases that backend cannot serve, so it gates the row
below it. Fits-in-GPU and context size share a band because they are one
control group: the context size is the length the VRAM estimate is computed at,
and that estimate is what the fits filter tests against.

Chips had no visible keyboard focus indicator. The global focus ring is wrapped
in :where(), so it carries the specificity of a bare :focus-visible, ties with
.filter-btn and loses on source order, leaving focused chips showing their
resting drop shadow. Restate the ring where it outranks both resting and hover.

Also: aria-pressed on the chips, a real label association and aria-valuetext on
the context slider (it steps over an index, so it announced "2"), disabled chip
styling moved off inline styles, a prefers-reduced-motion block for the chip
transition, and the hard-coded English "Context:" moved into all seven locales.

No behaviour change: same filters, same state, same requests. Page reset on
change, localStorage persistence and "Clear filters" verified unchanged.

* feat(ui): let the models recommendations panel fade into the background

The "Recommended for your hardware" strip rendered at full height on every
visit regardless of how many models were already installed, costing 186px at
1600px wide (287px at 1100px, where its cards wrapped to two rows) and pushing
the first gallery row to y=554 / y=703.

Make its prominence track how much the user still needs it. The panel now
defaults to a one-line summary once anything is installed, and both the
collapse choice and the existing dismissal persist:

  collapsed = explicit user choice, if one exists
            : installedCount > 0

The preference is three-valued on purpose. A boolean cannot tell "the user
expanded it" apart from "the user has never chosen", and those need opposite
handling when the installed count later crosses zero: someone who deliberately
opened the panel on an empty instance should not have it collapse out from
under them when their first model finishes installing.

Collapsed keeps the card, icon, title and a suggestion count, so the panel is
recovered by clicking what you are already looking at rather than by hunting.
Expanded is unchanged, because for a user with nothing installed it was never
the problem. Collapsed reclaims 145px at 1600 and 420, and 246px at 1100.

Models.jsx gains a statsLoaded flag: stats initializes to installed:0, so
reading it before the fetch resolves would render expanded and collapse a frame
later, which is exactly the layout shove this removes.

The dismissal key moves to the page's localai-models-* convention; the old
localai_rec_models_dismissed is still read, never written, so an existing
dismissal is honoured rather than resurrected by the rename.

Accessibility: the disclosure is a real button whose accessible name is the
visible title alone, with state on aria-expanded and aria-controls resolving in
both states, because the grid is hidden via the hidden attribute rather than
unmounted. That also keeps the four install buttons out of the tab order while
collapsed. The app's global focus ring applies; no per-component outline is
added, per the warning in App.css. Reveal animates opacity and transform only,
never height, and both it and the chevron rotation are disabled under
prefers-reduced-motion.

Only en had a recommended block, so the other six locales were falling back to
English for the whole panel. Translated the complete block rather than adding
one orphaned key to files that would still render the title in English.

* fix(downloader): recover from a leftover .partial on non-HTTP URIs

An interrupted download leaves a `<file>.partial` behind. The partial
handling in DownloadFileWithContext gated resume on `err == nil &&
uri.LooksLikeHTTPURL()`, so for any URI that is not literally http(s)
the branch fell through to `else if !errors.Is(err, os.ErrNotExist)`,
which with a nil err is true. The download then failed with an error
wrapping nil:

  failed to check file ".../Ternary-Bonsai-27B-Q2_g64.gguf" existence: <nil>

Every gallery file URI uses `huggingface://`, so a single interrupted
download made that model permanently uninstallable until someone
deleted the partial by hand. The `<nil>` in the message compounded it
by pointing debugging at a filesystem failure that never happened.

Restructure the handling as an explicit switch over the four real
states: partial exists and is resumable, partial exists and is not
resumable (discard and restart, as already done for an HTTP server
without range support), no partial, and a genuine stat failure. The
error branch is now only reachable with a non-nil error, names the
path that was actually stat'd, and wraps with %w.

Discarding is required for correctness and not merely convenience: the
writer opens the partial with O_APPEND, so an un-resumed download would
concatenate a fresh body onto stale bytes.

* feat(ui): tell the models gallery's variant rows apart, and let browsing see every build

Both variant surfaces rendered name, backend and size. For two builds of one
model that is close to no information: a variant exists precisely because the
same weights are offered another way, so the backend usually matches and the
sizes usually land within a few hundred megabytes. Comparing
ternary-bonsai-27b-pq2 against ternary-bonsai-27b-q2-g64 meant reading two names
that differ by a suffix nobody has defined anywhere in the UI.

Report the quantization and the serving features on VariantView, and derive both
server-side from the referenced entry rather than parsing names in the browser,
so every client reads the same format out of the same file the installer will
hand the backend.

Quantization comes from overrides.parameters.model first, falling back to the
file list. That order is load bearing: entries routinely ship a vision tower
alongside the language model at a different quantization, so reading the file
list first reports the mmproj's format. Matching walks `-` and `.` delimited
segments right to left; `_` deliberately does not split, because it separates the
parts INSIDE a quant token and splitting on it reports Q4 for a Q4_K_M build. A
second, looser pass takes a segment's `_`-delimited tail, which catches the
gemma-4-E2B_q4_0-it.gguf style; it runs second so a precise match can never lose
to a fuzzy one further right in the name. An entry naming no format reports
nothing, which is the honest answer for a backend served from a directory of
weights.

Features are the same tag-against-vocabulary match servingFeatureRank already
ranks on, over the same host preference list. A build can therefore never be
shown as faster than one selection did not actually reward, nor rewarded without
being shown; a spec pins that agreement rather than trusting it.

The compact dropdown gets the quantization on its meta line and the bare feature
token. The detail row, which has the room, gets the quantization as its own
monospaced column so precision lines up down the list, and the feature spelled
out, because DFLASH names nothing to a user who has not met it. The referenced
entry's description stays out of both: the detail row already renders the
parent's prose above the table, and a second block per variant would push a
three-variant list past a screen to restate what the columns now say precisely.

The collapse toggle comes back. 462583f38 dropped it once search bypassed the
collapse, on the reasoning that nothing was unreachable any more. That holds for
finding a build whose name you know and does not hold for browsing: no sequence
of actions enumerated the 68 builds the default view hides. Collapse is for
browsing and search is for finding, and the toggle was the browsing half.

It goes in the refinements band 0d4823362 established, not back among the
taxonomy chips where its position depended on how many chips happened to wrap. It
leads that band because it decides how many rows the other two refine over, and
because unlike fits-in-GPU it is unconditional: a host with no GPU still browses.

The search bypass is untouched and re-checked by a spec in the toggle's default
state, since restoring the control must not restore the dead end it replaced. The
empty-state hint returns but only without a search term, because a term bypasses
the collapse and the hint would otherwise point at a control that cannot change
the result. The stored preference reads 'on'/'off' only: an older build wrote
'1'/'0' from an effect that ran on mount, so those record that the page was
opened, not that anyone chose a view.

Also fixes a latent flake it exposed. The collapse_variants spec compared whole
response bodies byte for byte, and the listing envelope carries live host
telemetry that drifts between two calls milliseconds apart, so it was asserting
on the machine's memory pressure. It now compares everything the parameter
governs -- the entries, their serialization and the paging -- and is green 25/25
where it was failing about one run in three.

* feat(ui): let the models gallery show a variant's full details

The variant list in an entry's expanded detail row says how the builds
differ: name, backend, quantization, size, and the auto-selected, base
and serving-feature markers. It cannot say what any one of them is. A
variant's own description, tags, license, source links and file list are
unreachable anywhere in the UI, because while the collapse is on a
variant has no gallery row of its own.

Give each variant row an info control that reveals its entry, rendered by
the same ModelDetail a top-level row gets, so a field added to the detail
view appears here too. variantData is withheld from the nested render: a
variant may declare variants of its own, and recursing would nest a
picker inside a picker two levels deep already.

An inline disclosure rather than a modal. The control sits inside a table
row that is already expanded, inside a variant list within that; a dialog
opened from there stacks a dismissal on a dismissal for a handful of
extra fields about the entry the user is already reading, and breaks the
page's own expand idiom. The third level is carried by an inset and a
left rule instead of another card.

The entry is fetched by exact name from the listing, once, on first use.
The listing already returns every field the detail view renders, and a
search term bypasses the variant collapse server-side, so no new endpoint
is needed and neither the listing nor DescribeVariants gains any work.
Expanding a row costs nothing; a variant nobody opens costs nothing. A
name the listing no longer returns is stated, not blanked: an empty panel
reads as a rendering fault rather than as a lookup that came back empty.

The control is a sibling of the install button, not a descendant, so
asking about a build can never install it.

The variant list keeps its content-sized columns via a trailing filler
track instead of max-content sizing, so the rows are unchanged while the
panel spanning them gets the pane width its file table needs.

* feat(gallery): let search respect the collapse instead of switching it off

The models listing collapsed to one row per model, and an explicit search term
turned that off wholesale. Searching while collapsed therefore answered with the
individual builds a parent already offers, which are exactly the rows the view
the user asked for has no place for: typing "mtp" returned
qwen3.6-27b-nvfp4-mtp, a row that is invisible the moment the box is cleared.
The bypass was the right shape of fix for the wrong half of the problem. What a
search must not do is answer "no models found" for a build the gallery does
hold; that does not require abandoning the grouping the user asked for.

So the term is now matched against every entry either way, hidden builds
included, and the collapse decides how a match is reported rather than which
matches exist. Collapsing stops being a filter that drops rows and becomes a
substitution: a match on a build another entry offers is reported as that entry,
the one installable in its own right. Nothing becomes unfindable and nothing
comes back that the requested view cannot show.

Substitution happens after search, tag and backend, so every filter is judged
against the build that really carries the name, tag or backend rather than
against a parent that merely offers it; the other order would let backend=vllm
match a parent whose own backend is something else. The price is that the
surfaced row shows the parent's own metadata while the match was on a variant,
which is what grouping means, and the alternative is claiming the gallery holds
no such build. It happens before the count and the page math, so both describe
the rows actually handed out rather than the matches that produced them.

A parent already in the result keeps its own position and absorbs its matching
variants there, which is what leaves the browsing listing ordered exactly as it
was; a parent surfaced only by a variant takes the position of the first variant
that surfaced it. Either way it appears once, however many of its builds matched
and whether or not it matched itself. Search preserves gallery order rather than
scoring, so a surfaced parent has a real position rather than an invented one.

VariantParents never reports an entry that declares variants of its own, so a
parent is never itself hidden and one hop always lands on a visible row. The
handler follows exactly one anyway: refusing the second is what makes a gallery
the linter would have rejected terminate rather than loop.

The empty-state hint pointing at the toggle goes with it for every server-side
filter. Substitution means a match is always reported as some row, so the
collapse can no longer be why a term, a chip or a backend came back empty, and
naming it there sends the user to a control that cannot change the result. It
survives for the fits filter alone, which runs in the browser after the
substitution and judges the surfaced entry's own size: there the build that fits
really can be filtered out along with a parent that does not.

Searching a build's exact name while collapsed now answers with its parent, so
the result no longer contains the string the user typed. That is intended, and
the row is the one they can act on, but it is a real rough edge: nothing on the
row explains the connection. Closing it properly means reporting which variant
matched so the UI can say so, which the listing does not do today.

ResetGalleryModelCache is added for tests. The model cache is a package global
keyed by nothing, so a background refresh one spec triggers can land in the
middle of the next and answer it with the previous spec's gallery; the extra
specs here made that fail about one run in five. It waits for the in-flight
refresh to publish before clearing, since clearing alone only narrows the
window.

The empty-state starter widget recommended from a hardcoded list, which
drifts as the gallery evolves. Add useRecommendedModels: it queries the
live gallery for chat-capable models (their natural curated order, since
the gallery exposes no popularity signal), estimates size/VRAM for the top
candidates via the existing estimate endpoint, and ranks by hardware fit -
smallest on CPU-only boxes, largest-that-fits on GPUs.

* feat(ui): recommend models for your hardware in the gallery

Hardware-aware recommendations were only shown on the first-run empty
state. Surface them on the main Models gallery too: a dismissible
"Recommended for your hardware" strip at the top, sharing the
useRecommendedModels fit-ranking with the starter widget. CPU-only boxes
get small models; GPUs get the largest picks that fit VRAM, with size and
VRAM shown per card. One-click install; dismissal persists per browser.

* feat(ui): gpu-mid tier + NVIDIA NVFP4 model recommendations

Refine the hardware recommendation tiers and curated picks:

- Add a gpu-mid tier (8-24GB VRAM) between gpu-small and gpu-large, so
  ~27B-class models are suggested separately from the 30B+ large tier.
- Detect NVIDIA GPUs (resources.gpus[].vendor) and, on NVIDIA only, prefer
  NVFP4 + MTP variants (Blackwell-optimised); NVFP4 models are filtered out
  of recommendations on non-NVIDIA hardware where they can't run. This
  applies to both the live ranking and the static fallback, with an NVFP4
  badge shown on those picks.
- Refresh the curated fallback to current models: Gemma-4 QAT Q4 builds at
  every tier, low qwen3.5 (4B distilled / 9B) on CPU/small, qwen3.6-27b
  and MTP variants at mid, qwen3.6/qwen3.5 35B-A3B apex/distilled at large.
  All names verified against gallery/index.yaml.

LocalAI [bot]andEttore Di Giacinto 5c3d48ab50 feat(ui): usage & UX enhancements (last-used model, polling, starter models, usage cost, a11y) (#10496)
* feat(ui): remember last-used model per capability

ModelSelector auto-selected the first option whenever the bound value was
empty or stale, so every visit to the Home chat box, Image, TTS or Talk
pages reset the choice to whatever sorted first. Persist the user's pick
in localStorage keyed by capability and prefer it on auto-select when the
model is still available, falling back to the first option otherwise.

Because every modality picker funnels through ModelSelector, this fixes
the friction everywhere at once. External-options callers pass no
capability and keep the previous first-item behaviour.

* feat(ui): add visibility-aware polling hook

The app had 26 hand-rolled setInterval polls, none of which paused when
the browser tab was hidden, so backgrounded dashboards kept hitting the
server every few seconds for data nobody was looking at.

Add usePolling: runs immediately, polls on a fixed interval, pauses while
document.hidden, fires a catch-up poll on return, and guards against
overlapping slow requests. Route useResources (the highest-frequency
shared poll) through it. Further callers can be migrated incrementally.

* feat(ui): hardware-aware starter models on empty home

A fresh install dropped admins straight into a 1000+ model gallery with
no guidance. Add a StarterModels widget to the empty-state wizard that
recommends a small, curated set tuned to the detected hardware:

- CPU-only machines (no GPU VRAM) are steered to genuinely small models
  (1-4B, Q4) that stay responsive without a GPU.
- GPU machines get suggestions scaled to available VRAM.

Curated names are real gallery entries, intersected against the live
gallery at render time so a trimmed/custom gallery degrades gracefully.
Install is one click via the existing model-install API.

Also routes Home's cluster and system-info polls through usePolling so a
backgrounded home page stops fetching.

* feat(ui): optional token-cost estimates on usage dashboard

The usage dashboard tracked tokens but had no monetary view. Multi-user
deployments that bill back or budget compute had to export and compute
cost elsewhere.

Add an opt-in pricing control: admins set $ per 1M prompt/completion
tokens (stored per-browser). When set, an estimated-cost summary card and
per-model / per-user cost columns appear, computed from recorded token
counts. The entire cost surface stays hidden until a price is entered, so
the default view is unchanged. Cost is clearly labelled an estimate -
LocalAI itself has no notion of price.

of all icon-only buttons found these were the only two unlabeled controls;

M1: the desktop .top-navbar was hidden at max-width 768px while the
.mobile-header only appears at max-width 639px, leaving 640-768px with
neither bar so admins lost the mode pill, token meter and admin-via-chat
jump. Hide the top bar at 639px instead so it covers every width the rail
sidebar is shown and hands off to the mobile-header exactly at 639px.

M2: the navbar 'Admin via chat' button wrote localStorage and called
navigate('/app/chat'), but when already on the chat page Chat does not
remount so its mount-time payload reader never fired and the click was a
no-op until reload. The payload consume logic is factored into a shared
callback; the launcher now dispatches a localai-open-assistant event that
the mounted Chat listens for to re-consume the payload. Mount behavior is
unchanged.

LocalAI [bot]andEttore Di Giacinto 600dafd20b feat(ced): sound-event classification backend (CED audio tagger) (#10425)
* feat(ced): sketch sound-classification backend (CED audio tagger)

Wires ced.cpp (CED, 527-class AudioSet sound-event tagger; baby cry,
footsteps, glass, alarms, dog bark) into LocalAI as a Go/purego backend.

SKETCH (backend skeleton real; core REST wiring + CI/gallery is a checklist
in DESIGN.md):
- backend/backend.proto: new SoundDetection rpc + SoundClass messages
  (run `make protogen-go` to regenerate pkg/grpc/proto).
- backend/go/ced: main.go (purego dlopen libced.so + ced_capi.h),
  goced.go (Ced gRPC backend: Load + SoundDetection), Makefile
  (clone-at-pin CED_VERSION, ggml static-PIC shared build), run.sh,
  package.sh, .gitignore.
- DESIGN.md: REST /v1/audio/classification wiring (handler/route/capability
  registration checklist), gallery/index + CI registration, and a scoping
  note for the realtime/websocket live-recognition path (sliding-window
  classify over the existing ws transport + voicegate; the ced C-API
  per-PCM entry point is already window-friendly).

Backend code does not compile until protogen-go regenerates the pb types
and a libced.so is built (Makefile clones+builds it).

* feat(ced): REST /v1/audio/classification endpoint + capability registration

Wires the ced sound-event classification backend (AudioSet audio tagger)
end to end through the REST surface, mirroring the transcription path.

- Handler: core/http/endpoints/openai/sound_classification.go parses the
  multipart audio upload, temp-files it, resolves the model config and
  calls the SoundDetection RPC; returns {model, detections[]} JSON.
- Backend wrapper: core/backend/sound_classification.go (ModelSoundDetection)
  loads the model and normalizes the proto response into schema types.
- Schema: core/schema/sound_classification.go (SoundClassificationResult).
- gRPC layer: SoundDetection wired through the LocalAI wrapper (interface,
  Backend client, Client, embed, server, base default) so the loader-typed
  client exposes the RPC; proto regenerated via make protogen-go.
- Route: POST /v1/audio/classification (+ /audio/classification alias) with
  the audio/multipart default-model middleware in routes/openai.go.
- Capability surfaces: swagger @Tags/@Router on the handler; FLAG_SOUND_
  CLASSIFICATION usecase flag + UsecaseSoundClassification + UsecaseInfoMap +
  GuessUsecases + ModalityGroups + GetAllModelConfigUsecases; meta usecase
  option; /api/instructions audio area updated; auth RouteFeatureRegistry +
  FeatureAudioClassification (APIFeatures, default ON) + FeatureMetas; UI

* feat(ced): realtime sound-event detection over the websocket API

When a realtime pipeline configures a sound-classification model, each
VAD-committed utterance (the same window the transcription path produces)
is also run through the CED sound-event classifier and the scored AudioSet
tags are emitted as a new server event. No new backend rpc is needed: the
SoundDetection gRPC method already exists on this branch.

- config: add Pipeline.SoundDetection (yaml/json sound_detection,omitempty)
  beside Transcription/VAD.
- realtime: add Model.SoundDetection(ctx, audio, topK, threshold) to the
  ModelInterface; implement it on wrappedModel and transcriptOnlyModel by
  calling backend.ModelSoundDetection with the session's sound-classification
  model config (mirrors how Transcribe dispatches). Load the optional config
  in newModel / newTranscriptionOnlyModel; nil config keeps it additive.
- types: add ConversationItemSoundDetectionEvent (item_id, content_index,
  detections[]{label,score,index}) with type conversation.item.sound_detection,
  its ServerEventType constant and MarshalJSON, mirroring the transcription
  completed event.
- realtime: add emitSoundDetection (unary path: classify the committed window,
  build the event, t.SendEvent) and wire it at the utterance-commit hook right
  after emitTranscription; gated on session.SoundDetectionEnabled (resolved
  from Pipeline.SoundDetection at session setup, defaults top_k=5, threshold=0).
  Its error is logged via xlog but never aborts the turn.
- test: Ginkgo specs for emitSoundDetection (tags emitted, empty detections,
  classifier error) plus a SoundDetection method on the fakeModel double.

* fix(ced): implement SoundDetection in nodes backend test doubles

The SoundDetection method added to the grpc backend interface left two
test doubles (fakeBackendClient, fakeGRPCBackend) incomplete, so
core/services/nodes failed to compile under `go vet`/`go test` (go build
missed it: the doubles live in _test.go). Add the method to both,
mirroring their existing Detect mock. Repairs CI for the nodes package.

Signed-off-by: Ettore Di Giacinto <mudler@localai.io>

* feat(ced): decouple realtime sound detection from VAD (sound-only sessions)

Sound-event detection must activate on sounds, not speech, so it no longer
runs through the voice VAD/transcription path. A sound-detection-only
pipeline (sound_detection set, no transcription/LLM) now:

- is accepted by prepareRealtimeConfig (sound_detection counts as a pipeline
  stage),
- builds a lightweight model via newSoundDetectionOnlyModel (no VAD/STT/LLM/TTS
  loaded), and
- defaults the session to turn_detection none (no VAD) with no transcription
  stage, so the client drives windowing via input_audio_buffer.commit
  (option A: client-side sliding window). The per-PCM C-API already supports
  arbitrary windows.

commitUtterance gains a sound-only branch: it emits the
conversation.item.sound_detection event (scored AudioSet tags) and stops -
no transcription, no LLM response. generateResponse is now guarded on a
transcription stage being present, so a sound-only turn never invokes the LLM.

Existing transcription/VAD sessions are unchanged (additive). Added a
commitUtterance sound-only Ginkgo spec asserting it emits the sound event and
neither transcribes nor generates a response. go vet + golangci-lint
(new-from-merge-base) clean; openai suite green.

* feat(ced): register sound-classification backend in gallery + CI

Mechanical backend-image registration for the ced sound-event classifier,
mirroring the parakeet-cpp Go/purego backend everywhere it is wired up.

- .github/backend-matrix.yml: add the ced build matrix, field-for-field copies
  of the parakeet-cpp entries (cpu amd64/arm64, cublas cuda 12/13 amd64,
  l4t cuda-13 arm64, l4t-jetpack cuda-12 arm64, sycl f32/f16, vulkan
  amd64/arm64, rocm hipblas, and the metal darwin entry), changing only
  backend and tag-suffix. dockerfile stays ./backend/Dockerfile.golang.
- backend/index.yaml: add the &ced meta anchor (capabilities map per platform)
  plus ced-development and the per-arch image entries, each uri/mirror
  tag-suffix matching the matrix exactly. The model gallery (GGUF) entry is
  intentionally deferred pending the HuggingFace publish (TODO note inline).
- scripts/changed-backends.js: add an explicit item.backend === "ced" branch in
  inferBackendPath mapping to backend/go/ced/, same mechanism and ordering as
  the parakeet-cpp branch (before the generic golang fallthrough).
- .github/workflows/bump_deps.yaml: register mudler/ced.cpp -> CED_VERSION in
  backend/go/ced/Makefile so the daily bot bumps the pin.
- swagger/{docs.go,swagger.json,swagger.yaml}: regenerated via make swagger so
  the existing /v1/audio/classification annotations land in the generated spec.

* feat(ced): server-side windowing for realtime sound detection (option B)

Adds an optional server-driven sliding-window classifier so a sound-only
realtime client only has to stream audio (no input_audio_buffer.commit):

- Pipeline.sound_detection_window_ms / sound_detection_hop_ms config knobs.
  When both > 0 on a sound-only session, the server classifies the last
  window of streamed audio every hop and emits a conversation.item.sound_
  detection event; the input buffer is trimmed to one window so a long
  stream stays bounded. When unset, the session stays client-driven
  (option A). Runs independent of VAD (sound events are not speech).
- handleSoundWindow (ticker) + classifySoundWindow (one tick, extracted so
  it is unit-testable) + writeWindowWAV, which declares the true
  InputSampleRate (NewWAVHeaderWithRate) so the classifier resamples
  correctly. Goroutine is started after toggleVAD and torn down with the
  session (close + wg.Wait).
- Register pipeline.sound_detection (+window_ms/hop_ms) in the config meta
  registry; the earlier realtime commit added pipeline.sound_detection
  without a registry entry, failing TestAllFieldsHaveRegistryEntries. This
  fixes that and covers the two new knobs.

Tests: classifySoundWindow emits an event + trims the buffer to one window,
no-ops on too-little audio; writeWindowWAV declares the given sample rate.
go build/vet + golangci-lint (new-from-merge-base) clean; config + openai
suites green.

children (nested detail tables render normally), override inline min-width on
mobile, and pass through table/container inline styles. Nested expansion
tables in Nodes/Models/Manage are intentionally left as-is.

* feat(ui): unsaved-changes guard on the Fine-Tuning form

Editing the long fine-tune job form and navigating away silently discarded
everything. Snapshot the assembled getFormConfig() as a baseline, treat the
open form as dirty when it diverges, and reuse UnsavedChangesGuard to prompt
before leaving. The baseline is rebased after a job is submitted so leaving
afterward does not warn.

at semibold with the editorial fluid sizing and tight tracking. No serif
anywhere.

Active sidebar item is now a tint-only treatment (accent text + tinted
background); the left accent rail is removed and the shared base
.nav-item.active inset bar is suppressed in the sidebar (as the console
rail already does). Update the design-system e2e specs to assert the
sans display font and the tinted-background active state.

* refactor(ui): declutter Home - discoverable + dismissable API, vertical balance

Home felt overloaded and top-heavy. Three changes from review:
- The API endpoint catalog (12 endpoints) is collapsed by default behind a
  "Browse the API" disclosure; only the base URL + copy stay visible, so the
  catalog is discoverable without dominating the page.
- The whole connect card is dismissable (x): dismissing unmounts it so the
  vertical space is recovered, and the choice is remembered (localStorage).
- .home-page now fills its column and vertically centers its content when
  there is slack, so sparse states (no models / card dismissed) read as a
  balanced launcher instead of content jammed at the top. Overflow-safe:
  tall content flows from the top and scrolls.

Adds connect.browse / connect.hide / connect.dismiss i18n keys to all locales.

PageHeader now derives its eyebrow from the route's section/console (Build /

eyebrow with no per-page wiring (override with the eyebrow prop, suppress with
eyebrow={null}). Settings adopts it as the first consumer.

Also fix a navigation scroll bug: the default layout uses the document as its
scroll container and route changes did not reset it, so navigating the console
rail from a scrolled page landed mid-view. App now scrolls to top on pathname

VoiceVisualizer is self-contained: it builds its own AudioContext + analysers
from the output <audio> stream (speaking) and the mic stream (listening) so it
does not touch the existing WebRTC/diagnostics graph. Bars are status-tinted
(idle/connected/listening/speaking/error) and animate with a gentle idle wave
when not connected. Live mic/output animation is exercised on a real session.

Richard Palethorpe 3fa7b2955c feat(pii): NER tier engine — privacy-filter.cpp backend + NER-centric PII filter (#10360)
Squashed feat/pii-ner-tier-engine rebased onto master (was 45 commits; see
backup/pii-ner-tier-engine-prerebase). Net change:

- privacy-filter.cpp: standalone GGML engine for the openai-privacy-filter
  PII/NER token classifier, wired as a LocalAI gRPC backend (CPU/CUDA/Vulkan).
  TokenClassify moves off the patched llama.cpp path onto this backend.
- PII filter reworked to be NER-centric (encoder/NER detection tier scanning
  whole conversations as one document), with a recreated bounded restricted-
  regex secret-matching pattern detector tier alongside it (per-model
  pii_detection.builtins / .patterns + core/services/routing/piipattern).
- Detection labelled by source (ner vs pattern); backend trace / confidence /
  debug observability; analyze/redact exposed as a synchronous API.
- Instance-wide default detector policy + per-usecase default-on; request
  filtering extended to completions, embeddings, edits & Ollama.
- React UI: NER-centric PII editor, detector-models table, pattern/builtins
  editor, middleware default-policy UI.
- Gallery: privacy-filter-multilingual token-classify model + NER install
  filter; token_classify known_usecase; batch sized to context for NER models.
  privacy-filter backend registered in the backend gallery (cpu/vulkan/cuda-13
  meta + image entries with a capabilities map) matching its CI matrix jobs,
  and an /import-model auto-detect importer (PrivacyFilterImporter, narrow
  privacy-filter GGUF detection) replacing the prior pref-only registration.

Reconciled against master's independent evolution:

- Dropped master's PIIPatternOverrides feature (global-pattern runtime
  overrides + /api/pii/patterns API + runtime_settings.json persistence). The
  per-model NER + pattern-detector design supersedes it; it was built on the
  global redactor pattern set this branch replaced.
- Reverted the llama.cpp Score carry-patch (0006-server-task-type-score):
  removed the patch and restored master's grpc-server.cpp Score RPC (direct
  llama_decode, slot-loop bypass) and LLAMA_VERSION pin, plus master's
  model_config validation forbidding score + chat/completion/embeddings on
  llama-cpp. token_classify is unaffected (it runs on the privacy-filter
  backend, not llama-cpp).

Generalize the one-off admin console into a reusable ConsoleLayout driven by
a shared consoleConfig (single source of truth for the rail, its gating, and
the sidebar entry that opens it — removes the prior rail/sidebar drift).

- Promote Install Models to the top menu next to Home.
- Build and Operate are now console tiers (secondary rail); Create stays inline.
- Fold Recognition (Faces/Voices) into the Build console as a group alongside
  Automation and Training so it no longer feels split off.
- Style the console rail as a panel (header, grouped dividers, rounded active
  pills) with a hover nudge; sidebar items become inset rounded pills. The rail
  slide-in plays only when entering a console, not on item-to-item sub-nav
  (which remounts the layout), so switching no longer flashes the menu. All
  token-based (light + dark), respects reduced-motion.
- Add a delayed RouteFallback loader so lazy routes no longer flash blank;
  scoped inside ConsoleLayout so the rail stays put while the body loads.
- Update e2e specs for the new structure (.console-* classes, console entries).

* feat(ui): persist console layout across sub-nav + add drop-in endpoint section

  Cache /api/features across mounts and play the rail entrance animation only
  when actually entering a console.
- Add a "One endpoint, every API" section to Home: leads with LocalAI's own
  native API (images, video, realtime voice over WebRTC/WS, depth, object
  detection, rerank, audio/TTS, face & voice recognition) plus a Full API
  reference link, then the drop-in compatibility layer (OpenAI, Anthropic,
  Ollama, OpenAI Responses) with the live copyable base URL. All 7 locales.

* fix(react-ui): polish 'Fits in my GPU' filter to use design-system Toggle

The recently added VRAM-fit filter in the Models page used a raw
<input type="checkbox"> next to the themed range slider, breaking the
visual language of the rest of the row. Swap it for the shared
<Toggle> component (already used by Backends, Settings, Traces,
AgentCreate), adopt the filter-bar-group__toggle class to drop the
duplicated inline styles, add a fa-microchip icon to mirror the
per-row fit indicator, and add a subtle left divider so the filter
reads as separate from the context-size slider on its left.

* fix(react-ui): move 'Fits in GPU' filter to filter row and unify copy

Two follow-ups on the previous polish pass:

1. Move the toggle from the context-slider row into the filter-button
   row above. The toggle is a filter on the result set, not a config
   for VRAM estimation, so it belongs with the type chips and backend
   select. The context slider stays its own thing.

2. Unify the label copy. The same locale file had "Fits in my GPU"
   for the filter and "Fits in GPU" for the per-row indicator; pick
   the shorter, possessive-free variant everywhere (en/de/es/it/zh-CN).
   Update e2e selectors to match.

LocalAI [bot]andEttore Di Giacinto f0cb02afb8 feat(usage): attribute Sources rows to user accounts in admin view (#9935)
The merged feature (#9920) let admins see per-API-key and per-source
totals but did not surface which user owned each key, and lumped
every user's Web UI traffic into a single global Web UI row. This
makes the admin Sources tab properly per-user attributable:

- KeyTotal gains UserID + UserName, populated from the snapshot the
  usage middleware already records. The by_key roll-up now groups by
  (api_key_id, api_key_name, user_id, user_name).
- New SourceTotals.ByUserSource roll-up groups (source, user_id,
  user_name) for sources without a key identity (web, legacy). Only
  populated on the admin path (includeLegacy=true); the non-admin
  endpoint stays unchanged for backwards compatibility.
- SourcesTable accepts showUserColumn={isAdmin}; admin view renders
  a User column, makes the search match user name/id, and expands
  Web UI / legacy pseudo-rows from the global aggregate to one row
  per user using by_user_source.

source: 'legacy-api-key' user -> legacy, everything else -> web.
The backfill is idempotent (only touches NULL/empty rows).

* feat(usage): add GetUserUsageBySource aggregator

Groups by (bucket, source, api_key_id, api_key_name). Filters out
legacy by default. Returns both per-bucket detail and roll-ups
(by_source, by_key sorted desc and capped at 200, grand_total).

The MAX(created_at) projection is iterated via Rows().Scan into a
string column and parsed manually because the SQLite driver surfaces
the aggregated timestamp as a string, which database/sql refuses to
scan directly into time.Time. Postgres returns a real timestamp; the
same string path handles its RFC3339 form too.

locking the SQLite time-string parser behaviour.

branches it also stores the resolved *UserAPIKey under auth_apikey

* refactor(usage): bound batcher intake and add Shutdown/FlushNow hooks

The pre-existing usage batcher had no cap on its add() path; the
usageMaxPending=5000 constant only guarded the re-queue path after
a failed write, leaving memory growth unbounded if the DB fell
behind. This commit:

- 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.
- Re-queue on failed flush is now cap-aware: prepends as much of the
  failed batch as fits alongside concurrent arrivals, instead of
  dropping the whole batch when full.

* feat(usage): drain usage batcher on graceful shutdown

Registers ShutdownUsageRecorder with the existing

LocalAI [bot]andEttore Di Giacinto 11d5bd0cc3 fix(react-ui/chat): stop wiping selection on every /api/operations poll (#9904) (#9917)
useOperations() was calling setOperations() with a fresh array on every
1s poll, even when the payload was identical. In React 19 the DOM diff
no longer short-circuits dangerouslySetInnerHTML on equal __html, so the
forced Chat re-render re-assigned innerHTML on every assistant message
once per second — wiping any text the user had selected.

Skip the state update when the serialised operations payload is
unchanged, and switch loading/error to functional setters so they also
short-circuit at the source.

Also fixes the chat copy button on plain HTTP: navigator.clipboard is
undefined in non-secure contexts (a common LXC+Docker deployment), but
the previous code called it unconditionally and showed a success toast
regardless. Routed Chat, AgentChat and CanvasPanel through a new
copyToClipboard() helper that uses navigator.clipboard when available
and falls back to a hidden-textarea + execCommand('copy') trick that
browsers still honour outside secure contexts. The fallback preserves
the user's existing selection.

Regression coverage in e2e/chat-polling-selection.spec.js: a
MutationObserver counts mutations on the assistant content node across
3s of polling (must be 0); the copy test stubs out navigator.clipboard
and asserts that execCommand('copy') is invoked.

Richard Palethorpe 0245b33eab feat(realtime): Add Liquid Audio s2s model and assistant mode on talk page (#9801)
* feat(liquid-audio): add LFM2.5-Audio any-to-any backend + realtime_audio usecase

Wires LiquidAI's LFM2.5-Audio-1.5B as a self-contained Realtime API model:
single engine handles VAD, transcription, LLM, and TTS in one bidirectional
stream — drop-in alternative to a VAD+STT+LLM+TTS pipeline.

Backend
- backend/python/liquid-audio/ — new Python gRPC backend wrapping the
  `liquid-audio` package. Modes: chat / asr / tts / s2s, voice presets,
  Load/Predict/PredictStream/AudioTranscription/TTS/VAD/AudioToAudioStream/
  Free and StartFineTune/FineTuneProgress/StopFineTune. Runtime monkey-patch
  on `liquid_audio.utils.snapshot_download` so absolute local paths from
  LocalAI's gallery resolve without a HF round-trip. soundfile in place of
  torchaudio.load/save (torchcodec drags NVIDIA NPP we don't bundle).
- backend/backend.proto + pkg/grpc/{backend,client,server,base,embed,
  interface}.go — new AudioToAudioStream RPC mirroring AudioTransformStream
  (config/frame/control oneof in; typed event+pcm+meta out).
- core/services/nodes/{health_mock,inflight}_test.go — add stubs for the
  new RPC to the test fakes.

Config + capabilities
- core/config/backend_capabilities.go — UsecaseRealtimeAudio, MethodAudio
  ToAudioStream, UsecaseInfoMap entry, liquid-audio BackendCapability row.
- core/config/model_config.go — FLAG_REALTIME_AUDIO bitmask, ModalityGroups
  membership in both speech-input and audio-output groups so a lone flag
  still reads as multimodal, GetAllModelConfigUsecases entry, GuessUsecases
  branch.

Realtime endpoint
- core/http/endpoints/openai/realtime.go — extract prepareRealtimeConfig()
  so the gate is unit-testable; accept realtime_audio models and self-fill
  empty pipeline slots with the model's own name (user-pinned slots win).
- core/http/endpoints/openai/realtime_gate_test.go — six specs covering nil
  cfg, empty pipeline, legacy pipeline, self-contained realtime_audio,
  user-pinned VAD slot, and partial legacy pipeline.

UI + endpoints
- core/http/routes/ui.go — /api/pipeline-models accepts either a legacy
  VAD+STT+LLM+TTS pipeline or a realtime_audio model; surfaces a
  self_contained flag so the Talk page can collapse the four cards.
- core/http/routes/ui_api.go — realtime_audio in usecaseFilters.
- core/http/routes/ui_pipeline_models_test.go — covers both code paths.
- core/http/react-ui/src/pages/Talk.jsx — self-contained badge instead of
  the four-slot grid; rename Edit Pipeline → Edit Model Config; less
  pipeline-specific wording.
- core/http/react-ui/src/pages/Models.jsx + locales/en/models.json — new
  realtime_audio filter button + i18n.
- core/http/react-ui/src/utils/capabilities.js — CAP_REALTIME_AUDIO.
- core/http/react-ui/src/pages/FineTune.jsx — voice + validation-dataset
  fields, surfaced when backend === liquid-audio, plumbed via
  extra_options on submit/export/import.

Gallery + importer
- gallery/liquid-audio.yaml — config template with known_usecases:
  [realtime_audio, chat, tts, transcript, vad].
- gallery/index.yaml — four model entries (realtime/chat/asr/tts) keyed by
  mode option. Fixed pre-existing `transcribe` typo on the asr entry
  (loader silently dropped the unknown string → entry never surfaced as a
  transcript model).
- gallery/lfm.yaml — function block for the LFM2 Pythonic tool-call format
  `<|tool_call_start|>[name(k="v")]<|tool_call_end|>` matching
  common_chat_params_init_lfm2 in vendored llama.cpp.
- core/gallery/importers/{liquid-audio,liquid-audio_test}.go — detector
  matches LFM2-Audio HF repos (excludes -gguf mirrors); mode/voice
  preferences plumbed through to options.
- core/gallery/importers/importers.go — register LiquidAudioImporter
  before LlamaCPPImporter.
- pkg/functions/parse_lfm2_test.go — seven specs for the response/argument
  regex pair on the LFM2 pythonic format.

Build matrix
- .github/backend-matrix.yml — seven liquid-audio targets (cuda12, cuda13,
  l4t-cuda-13, hipblas, intel, cpu amd64, cpu arm64). Jetpack r36 cuda-12
  is skipped (Ubuntu 22.04 / Python 3.10 incompatible with liquid-audio's
  3.12 floor).
- backend/index.yaml — anchor + 13 image entries.
- Makefile — .NOTPARALLEL, prepare-test-extra, test-extra,
  docker-build-liquid-audio.

Docs
- .agents/plans/liquid-audio-integration.md — phased plan; PR-D (real
  any-to-any wiring via AudioToAudioStream), PR-E (mid-audio tool-call
  detector), PR-G (GGUF entries once upstream llama.cpp PR #18641 lands)
  remain.
- .agents/api-endpoints-and-auth.md — expand the capability-surface
  checklist with every place a new FLAG_* needs to be registered.

* feat(realtime): function calling + history cap for any-to-any models

Three pieces, all on the realtime_audio path that just landed:

1. liquid-audio backend (backend/python/liquid-audio/backend.py):
   - _build_chat_state grows a `tools_prelude` arg.
   - new _render_tools_prelude parses request.Tools (the OpenAI Chat
     Completions function array realtime.go already serialises) and
     emits an LFM2 `<|tool_list_start|>…<|tool_list_end|>` system turn
     ahead of the user history. Mirrors gallery/lfm.yaml's `function:`
     template so the model sees the same prompt shape whether served
     via llama-cpp or here. Without this the backend silently dropped
     tools — function calling was wired end-to-end on the Go side but
     the model never saw a tool list.

2. Realtime history cap (core/http/endpoints/openai/realtime.go):
   - Session grows MaxHistoryItems int; default picked by new
     defaultMaxHistoryItems(cfg) — 6 for realtime_audio models (LFM2.5
     1.5B degrades quickly past a handful of turns), 0/unlimited for
     legacy pipelines composing larger LLMs.
   - triggerResponse runs conv.Items through trimRealtimeItems before
     building conversationHistory. Helper walks the cut left if it
     would orphan a function_call_output, so tool result + call pairs
     stay intact.
   - realtime_gate_test.go: specs for defaultMaxHistoryItems and
     trimRealtimeItems (zero cap, under cap, over cap, tool-call pair
     preservation).

3. Talk page (core/http/react-ui/src/pages/Talk.jsx):
   - Reuses the chat page's MCP plumbing — useMCPClient hook,
     ClientMCPDropdown component, same auto-connect/disconnect effect
     pattern. No bespoke tool registry, no new REST endpoints; tools
     come from whichever MCP servers the user toggles on, exactly as
     on the chat page.
   - sendSessionUpdate now passes session.tools=getToolsForLLM(); the
     update re-fires when the active server set changes mid-session.
   - New response.function_call_arguments.done handler executes via
     the hook's executeTool (which round-trips through the MCP client
     SDK), then replies with conversation.item.create
     {type:function_call_output} + response.create so the model
     completes its turn with the tool output. Mirrors chat's
     client-side agentic loop, translated to the realtime wire shape.

UI changes require a LocalAI image rebuild (Dockerfile:308-313 bakes
react-ui/dist into the runtime image). Backend.py changes can be
swapped live in /backends/<id>/backend.py + /backend/shutdown.

* feat(realtime): LocalAI Assistant ("Manage Mode") for the Talk page

Mirrors the chat-page metadata.localai_assistant flow so users can ask the
realtime model what's loaded / installed / configured. Tools are run
server-side via the same in-process MCP holder that powers the chat
modality — no transport switch, no proxy, no new wire protocol.

Wire:
- core/http/endpoints/openai/realtime.go:
  - RealtimeSessionOptions{LocalAIAssistant,IsAdmin}; isCurrentUserAdmin
    helper mirrors chat.go's requireAssistantAccess (no-op when auth
    disabled, else requires auth.RoleAdmin).
  - Session grows AssistantExecutor mcpTools.ToolExecutor.
  - runRealtimeSession, when opts.LocalAIAssistant is set: gate on admin,
    fail closed if DisableLocalAIAssistant or the holder has no tools,
    DiscoverTools and inject into session.Tools, prepend
    holder.SystemPrompt() to instructions.
  - Tool-call dispatch loop: when AssistantExecutor.IsTool(name), run
    ExecuteTool inproc, append a FunctionCallOutput to conv.Items, skip
    the function_call_arguments client emit (the client can't execute
    these — it doesn't know about them). After the loop, if any
    assistant tool ran, trigger another response so the model speaks the
    result. Mirrors chat's agentic loop, driven server-side rather than
    via client round-trip.

- core/http/endpoints/openai/realtime_webrtc.go: RealtimeCallRequest
  gains `localai_assistant` (JSON omitempty). Handshake calls
  isCurrentUserAdmin and builds RealtimeSessionOptions.

- core/http/react-ui/src/pages/Talk.jsx: admin-only "Manage Mode"
  checkbox under the Tools dropdown; passes localai_assistant: true to
  realtimeApi.call's body, captured in the connect callback's deps.

Mirroring chat's pattern means the in-process MCP tools surface "just
works" for the Talk page without exposing a Streamable-HTTP MCP endpoint
(which was the alternative). Clients with their own MCP servers can
still use the existing ClientMCPDropdown path in parallel; the realtime
handler distinguishes them by AssistantExecutor.IsTool() at dispatch
time.

* feat(realtime): render Manage Mode tool calls in the Talk transcript

Previously the realtime endpoint only emitted response.output_item.added
for the FunctionCall item, and Talk.jsx's switch ignored the event — so
server-side tool runs were invisible in the UI. The model would speak
the result but the user had no way to see what tool was actually
called.

realtime.go: after executing an assistant tool inproc, emit a second
output_item.added/.done pair for the FunctionCallOutput item. Mirrors
the way the chat page displays tool_call + tool_result blocks.

Talk.jsx: handle both response.output_item.added and .done. Render
FunctionCall (with arguments) and FunctionCallOutput (pretty-printed
JSON when possible) as two transcript entries — `tool_call` with the
wrench icon, `tool_result` with the clipboard icon, both in mono-space
secondary-colour. Resets streamingRef after the result so the next
assistant text delta starts a fresh transcript entry instead of
appending to the previous turn.

* refactor(realtime): bound the Manage Mode tool-loop + preserve assistant tools

Fallout from a review pass on the Manage Mode patches:

- Bound the server-side agentic loop. triggerResponse used to recurse on
  executedAssistantTool with no cap — a model that kept calling tools
  would blow the goroutine stack. New maxAssistantToolTurns = 10 (mirrors
  useChat.js's maxToolTurns). Public triggerResponse is now a thin shim
  over triggerResponseAtTurn(toolTurn int); recursion increments the
  counter and stops at the cap with an xlog.Warn.

- Preserve Manage Mode tools across client session.update. The handler
  used to blindly overwrite session.Tools, so toggling a client MCP
  server mid-session silently wiped the in-process admin tools. Session
  now caches the original AssistantTools slice at session creation and
  the session.update handler merges them back in (client names win on
  collision — the client is explicit).

- strconv.ParseBool for the localai_assistant query param instead of
  hand-rolled "1" || "true". Mirrors LocalAIAssistantFromMetadata.

- Talk.jsx: render both tool_call and tool_result on
  response.output_item.done instead of splitting them across .added and
  .done. The server's event pairing (added → done) stays correct; the
  UI just doesn't need to inspect both phases of the same item. One
  switch case instead of two, no behavioural change.

Out of scope (noted for follow-ups): extract a shared assistant-tools
helper between chat.go and realtime.go (duplication is small enough
that two parallel implementations stay readable for now), and an i18n
key for the Manage Mode helper text (Talk.jsx doesn't use i18n
anywhere else yet).

* ci(test-extra): wire liquid-audio backend smoke test

The backend ships test.py + a `make test` target and is listed in
backend-matrix.yml, so scripts/changed-backends.js already writes a
`liquid-audio=true|false` output when files under backend/python/liquid-audio/
change. The workflow just wasn't reading it.

- Expose the `liquid-audio` output on the detect-changes job
- Add a tests-liquid-audio job that runs `make` + `make test` in
  backend/python/liquid-audio, gated on the per-backend detect flag

The smoke covers Health() and LoadModel(mode:finetune); fine-tune mode
short-circuits before any HuggingFace download (backend.py:192), so the
job needs neither weights nor a GPU. The full-inference path remains
gated on LIQUID_AUDIO_MODEL_ID, which CI doesn't set.

The four new Go test files (core/gallery/importers/liquid-audio_test.go,
core/http/endpoints/openai/realtime_gate_test.go,
core/http/routes/ui_pipeline_models_test.go, pkg/functions/parse_lfm2_test.go)
are already picked up by the existing test.yml workflow via `make test` →
`ginkgo -r ./pkg/... ./core/...`; their packages all carry RunSpecs entries.

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,

* 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.

* fix(http): redact secrets from trace buffer and distribution-token logs

The /api/traces buffer captured Authorization, Cookie, Set-Cookie, and
API-key headers verbatim from every request when tracing was enabled. The
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.

The shared 5/min/IP limit on auth endpoints is right for password-style

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

unsafe values ("", ".", "..", "/").

localStorage is shared across same-origin pages; an XSS that lands once
can poison persisted MCP server config to attempt header injection or
to feed a non-http URL into the fetch path on subsequent loads.

scheme, header keys/values must be control-char-free. Drop anything
that doesn't fit.

"//evil.com" turned the SPA-shell redirect helper at /, /browse, and
/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.

* 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.

minLength={12} on the new-password input let the browser block the

focused the field, showed a brief native tooltip, and that was that —
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.

* fix(react-ui): bundle Geist fonts locally instead of fetching from Google

The new CSP correctly refused to apply styles from
fonts.googleapis.com because style-src is locked to 'self' and
'unsafe-inline'. Loosening the CSP would defeat its purpose; the
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.

Side benefit: no third-party tracking via Referer / IP on every UI
load, no failure mode when offline / behind a captive portal.

* 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).

Richard Palethorpe bb033b16a9 feat: add LocalVQE backend and audio transformations UI (#9640)
feat(audio-transform): add LocalVQE backend, bidi gRPC RPC, Studio UI

Introduce a generic "audio transform" capability for any audio-in / audio-out
operation (echo cancellation, noise suppression, dereverberation, voice
conversion, etc.) and ship LocalVQE as the first backend implementation.

Backend protocol:
- Two new gRPC RPCs in backend.proto: unary AudioTransform for batch and
  bidirectional AudioTransformStream for low-latency frame-by-frame use.
  This is the first bidi stream in the proto; per-frame unary at LocalVQE's
  16 ms hop would be RTT-bound. Wire it through pkg/grpc/{client,server,
  embed,interface,base} with paired-channel ergonomics.

LocalVQE backend (backend/go/localvqe/):
- Go-Purego wrapper around upstream liblocalvqe.so. CMake builds the upstream
  shared lib + its libggml-cpu-*.so runtime variants directly — no MODULE
  wrapper needed because LocalVQE handles CPU feature selection internally
  via GGML_BACKEND_DL.
- Sets GGML_NTHREADS from opts.Threads (or runtime.NumCPU()-1) — without it
  LocalVQE runs single-threaded at ~1× realtime instead of the documented
  ~9.6×.
- Reference-length policy: zero-pad short refs, truncate long ones (the
  trailing portion can't have leaked into a mic that wasn't recording).
- Ginkgo test suite (9 always-on specs + 2 model-gated).

HTTP layer:
- POST /audio/transformations (alias /audio/transform): multipart batch
  endpoint, accepts audio + optional reference + params[*]=v form fields.
  Persists inputs alongside the output in GeneratedContentDir/audio so the
  React UI history can replay past (audio, reference, output) triples.
- GET /audio/transformations/stream: WebSocket bidi, 16 ms PCM frames
  (interleaved stereo mic+ref in, mono out). JSON session.update envelope
  for config; constants hoisted in core/schema/audio_transform.go.
- ffmpeg-based input normalisation to 16 kHz mono s16 WAV via the existing
  utils.AudioToWav (with passthrough fast-path), so the user can upload any
  format / rate without seeing the model's strict 16 kHz constraint.
- BackendTraceAudioTransform integration so /api/backend-traces and the
  Traces UI light up with audio_snippet base64 and timing.
- Routes registered under routes/localai.go (LocalAI extension; OpenAI has
  no /audio/transformations endpoint), traced via TraceMiddleware.

Auth + capability + importer:
- FLAG_AUDIO_TRANSFORM (model_config.go), FeatureAudioTransform (default-on,
  in APIFeatures), three RouteFeatureRegistry rows.
- localvqe added to knownPrefOnlyBackends with modality "audio-transform".
- Gallery entry localvqe-v1-1.3m (sha256-pinned, hosted on
  huggingface.co/LocalAI-io/LocalVQE).

React UI:
- New /app/transform page surfaced via a dedicated "Enhance" sidebar
  section (sibling of Tools / Biometrics) — the page is enhancement, not
  generation, so it lives outside Studio. Two AudioInput components
  (Upload + Record tabs, drag-drop, mic capture).
- Echo-test button: records mic while playing the loaded reference through
  the speakers — the mic naturally picks up speaker bleed, giving a real
  (mic, ref) pair for AEC testing without leaving the UI.
- Reusable WaveformPlayer (canvas peaks + click-to-seek + audio controls)
  and useAudioPeaks hook (shared module-scoped AudioContext to avoid
  hitting browser context limits with three players on one page); migrated
  TTS, Sound, Traces audio blocks to use it.
- Past runs saved in localStorage via useMediaHistory('audio-transform') —
  the history entry stores all three URLs so clicking re-renders the full
  triple, not just the output.

Build + e2e:
- 11 matrix entries removed from .github/workflows/backend.yml (CUDA, ROCm,
  SYCL, Metal, L4T): upstream supports only CPU + Vulkan, so we ship those
  two and let GPU-class hardware route through Vulkan in the gallery
  capabilities map.
- tests-localvqe-grpc-transform job in test-extra.yml (gated on
  detect-changes.outputs.localvqe).
- New audio_transform capability + 4 specs in tests/e2e-backends.
- Playwright spec suite in core/http/react-ui/e2e/audio-transform.spec.js
  (8 specs covering tabs, file upload, multipart shape, history, errors).

Docs:
- New docs/content/features/audio-transform.md covering the (audio,
  reference) mental model, batch + WebSocket wire formats, LocalVQE param
  keys, and a YAML config example. Cross-links from text-to-audio and
  audio-to-text feature pages.

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.
