* backend(audio-cpp): add the native build scaffold

Links 0xShug0/audio.cpp engine_runtime through its public framework headers
and serves Health/Status. Model loading and the audio RPCs follow.

* backend(audio-cpp): keep the build-tree rpath at $ORIGIN

Upstream sets CMAKE_BUILD_WITH_INSTALL_RPATH in its own directory scope, so
CMake was appending its build-tree library dir to our target and baking an
absolute build-host path into the shipped binary. Set BUILD_WITH_INSTALL_RPATH
on the target so a package that forgets to bundle libggml*.so fails on the
build machine too, instead of only on a user's box.

Also document why EXCLUDE_FROM_ALL must stay on the add_subdirectory call,
correct the claim that Ubuntu ships no gRPC CMake config, stop the pin comment
from repeating the assignment token that bump_deps.sh rewrites, and make
test-engine fail rather than pass when no test is registered.

* backend(audio-cpp): reject out-of-range numeric model options

std::atoi is undefined once the digits exceed long and in practice wraps, so
device:2147483648 was accepted and handed the ggml backend selector a device
index of -2147483648 from a function whose error text promises a non-negative
integer. Parse with strtol and reject on ERANGE, on a value above INT_MAX, and
on any unconsumed trailing input. The error strings are unchanged.

Name the whole entry in the unknown-key error too: an entry like ':value' has
an empty key and left the user nothing to grep for in their YAML.

Tests look keys up through a helper instead of map::at, so a prefix off-by-one
fails one named check rather than aborting the binary and skipping the rest of
the suite, and cover the overflow, negative and non-numeric paths.

* backend(audio-cpp): use upstream's 'spk' task name and pin the preference order

The SpeakerRecognition short name was 'spkrec', which audio.cpp neither prints
nor parses; a name copied out of audio.cpp was rejected and a pinned 'spkrec'
would not survive the engine boundary. Emit 'spk', keep 'spkrec' as an
input-only alias, and correct the known-tasks lists.

Three assertions were vacuous because their fixtures advertised a single task,
so reversing a preference order or dropping the RPC name and the attempted
pairs from the capability error all passed. Give them fixtures that can tell
the orderings apart.

* backend(audio-cpp): convert sample, time and PCM units

* backend(audio-cpp): harden seconds_to_samples against NaN and overflow

seconds_to_samples is the one entry point fed by untrusted-shaped input: a
float-seconds timestamp off the wire, or a boundary from a model that diverged.
Its guard covered only the low side, so NaN and out-of-range values fell through
to an undefined double-to-int64 cast and came back as INT64_MIN. A hugely
negative sample index used later as an offset or a length is a wild pointer
rather than merely a wrong timestamp. Reject NaN with the !(x > 0) form and
saturate before the cast.

Also round instead of truncating there. These functions exist to cross the float
seconds boundary the VAD and diarize messages use, and truncation lost a sample
about half the time on the samples-to-seconds-and-back round trip, starting at
n=1.

Pin the decode scale at INT16_MIN, pin nanosecond truncation on a nonzero
fraction, and record why the clamp argument order in f32_to_s16le is
load-bearing for NaN.

* backend(audio-cpp): map NaN PCM samples to silence explicitly

f32_to_s16le relied on std::min argument order to keep a NaN sample away from
std::lround, whose result is unspecified for NaN. That was too subtle to rest on
a comment, and the comment was itself wrong: it warned against a spelling that
the outer std::max already catches, while three real spellings leak, including
std::clamp, which is the idiomatic C++17 way to write the same clamp and so the
likeliest future edit.

Divert NaN before the clamp and encode it as 0. A NaN sample rendered as a
full-scale click is worse audio than a dropped one, and this unit converts audio
that may have originated off the wire.

Pin it with an exact-value check rather than a range check, since all three
outcomes the plausible spellings produce are finite and inside full scale, plus
an invalid-operation check that fails unless the NaN is diverted before any
ordered comparison. That second check is what catches modernizing the clamp and
dropping the guard together.

Also bound the seconds round-trip comment, which claimed unconditionally what
holds only below roughly 2^23 samples, and document NaN, saturation and that
bound in the header.

* backend(audio-cpp): assemble transcripts from runtime spans

The top-level transcript text is TaskResult.text_output verbatim. audio.cpp
carries text nowhere else: speech_segments, speaker_turns and word_timestamps
hold spans and labels only, so deriving the text from them empties the
transcript for any producer that omits word timing, VibeVoice diarized ASR
included. Fixtures cover every observed producer shape.

* backend(audio-cpp): keep a nested speaker turn's own label

A segment sourced from speaker_turns re-derived its speaker by greatest
overlap. A turn's overlap with its own span is the largest possible, so a turn
nested inside another speaker's turn could only tie with the container, and the
tie went to whichever came first. sortformer_diar binarizes each speaker
independently and sorts by start sample, so the container always comes first
and the interjecting speaker was silently erased from DiarizeSegment.speaker.
choose_segment_spans now carries the label out with the span.

Also pins the nearest-segment fallback against measuring from either endpoint
or from segment position, which a trailing-only stray word could not do, and
exercises the empty-word guard in join_words. Two fixtures that pin a rule but
do not mirror any pinned family are relabelled defensive.

* backend(audio-cpp): serialize runs with a wedge-aware guard

audio.cpp sessions are not reentrant and a wedged CUDA call cannot be
cancelled, so a plain mutex would pile every worker thread behind a stuck GPU.
Callers waiting past the configured bound, or arriving while the holder has
already overrun it, fail fast instead.

A caller that queues behind a healthy run deliberately does not stamp the
clock: only the thread that takes the lock does. Stamping on arrival would
restart the wedge clock on every request and hide a stuck run from everyone
behind it, which is the pile-up this guard exists to prevent.

* backend(audio-cpp): serialize inference through an InferenceLane

One audio.cpp model is loaded per backend process and its sessions are not
reentrant, so concurrent gRPC handlers have to take turns. Serialization alone
is not enough: a wedged GPU call cannot be cancelled from userspace, so an
unbounded queue behind one stuck run would swallow every gRPC worker thread
until the process is useless.

InferenceLane gives handlers a lane with room for one runner. LaneEntry occupies
it for a scope and gives it back on every exit, including an exception, and is
the only way to take the lane at all: occupy/vacate are private with LaneEntry
as the sole friend, so a caller cannot acquire without holding something that
releases. LaneEntry is immovable on purpose, because a moved-from entry would
have to stop releasing while the lane still recorded it as occupied.

A caller either waits indefinitely or brings a millisecond budget. A bounded
caller that cannot get in fails instead of waiting on, and a bounded caller
whose budget is already shorter than the age of the run in the lane fails
immediately, which is what stops a queue forming behind a wedged run. The two
failures carry different text: one names the wait it exhausted, the other states
the measured age of the run without claiming to know why it is long, since a
short budget meeting a legitimately long run lands there too.

The run's age is stamped only after acquisition. A waiter that published itself
as holder would restart the measurement and hide a genuinely stuck holder from
every caller behind it.

Budget negotiation and the overrun decision are pure functions taking their
inputs explicitly, so both are covered without threads or sleeping. The
per-model ceiling arrives as an int of milliseconds; a request may tighten it
and may never loosen it.

Replaces the previous run_guard unit, which was a derivative of an
Apache-2.0 file upstream and could not stay in an MIT tree. Written from a
behaviour contract with no reference to the removed code.

Tests: 65 checks, standard library only, single translation unit, clean under
-Wall -Wextra. Mutation tested at 23/23 killed; two of those mutants exposed
missing coverage and the tests were extended until they died. ThreadSanitizer
clean.

* backend(audio-cpp): make the B10 test able to fail, and document LaneEntry

Review of the previous commit found the B10 test could not fail for the reason
it was named. It aged the in-flight run to about 120 ms and then tried two
budgets, 30 ms and 60 ms, both under that age, so both callers took the
fail-fast path. "The two failure modes do not share one message" was comparing
two fail-fast messages that differ only in the budget they print, and the
timeout path was never reached. The second budget is now 400 ms, well over the
run's age, so that caller queues and times out, and a new check asserts which
path each caller took instead of inferring it from inequality. A mutant that
makes the fail-fast path emit the timeout message previously died only on B4 and
B8 checks; it now also dies on B10.

Comment-only changes elsewhere. LaneEntry now says it is not reentrant and does
not detect reentrancy: a second entry on a thread that already holds the lane
surfaces as LaneUnavailable with a positive budget, but parks silently in
unbounded mode, which matters because a handler may hold one across a whole
stream. The immovability note now names the shapes that work, an optional
emplaced in place or a unique_ptr, rather than saying to hold the entry
indirectly without saying how; all three documented forms were compiled before
being written down, which is how the note came to say that an optional of an
immovable type cannot itself be returned.

The header's explanation of why fail-fast exists is reworded. Two clauses traced
back to a specification written after reading the Apache-2.0 upstream header,
and while that was judged de minimis, this unit was rewritten precisely to carry
no upstream expression at all.

The margin table in the report was also wrong about which wall-clock margins are
load-sensitive: there are four, not one, and the tightest is the B3 arrival
check, which is now flagged at the call site. No margin value changed and none
moved across 65 runs.

* backend(audio-cpp): gate model loading on the audio.cpp family

* backend(audio-cpp): load models and cache sessions per task

Loads one ILoadedVoiceModel and creates an IVoiceTaskSession lazily per
(task, mode), so the same model serves both the unary and streaming RPCs.
LoadModel derives the family from GGUF metadata or an explicit option and
fails with INVALID_ARGUMENT otherwise, so a failed load is a gRPC error the
backend probe can see.

audiocpp_backend::Task mirrors engine::runtime::VoiceTaskKind positionally,
and drift there is silent: every unit still compiles and every test still
passes while the backend runs a different task. Two mechanisms pin it. The
static_asserts in loaded_model.cpp catch an insertion or a reorder, and
-Werror=switch on that one file turns an appended upstream enumerator into a
build failure rather than a warning in a 600 file log.

* backend(audio-cpp): stop aborting the process on SIGTERM

The signal handler called grpc::Server::Shutdown directly. Shutdown takes an
absl::Mutex, which is not async-signal-safe: the handler can interrupt a thread
already holding that mutex, and abseil's deadlock detector responds by aborting.
Every SIGTERM therefore ended in exit 134 and a 'dying due to potential
deadlock' stack rather than a drained shutdown.

The handler now sets a lock-free atomic and returns. Server::Wait moves to a
helper thread so the main thread can poll that flag and call Shutdown itself,
outside any signal context. A condition variable would not have helped, because
notifying one from a handler is not async-signal-safe either.

SIGTERM and SIGINT both exit 0 with no stack trace, where both previously
exited 134.

* backend(audio-cpp): correct the status, lifetime and state contracts of LoadedModel

An environment fault during session creation was reported as UNIMPLEMENTED. A
missing libggml-cpu-*.so surfaced to the client as 'family silero_vad advertises
vad/offline but refused to create the session: Failed to initialize CPU
backend', which tells LocalAI the model cannot do this and must never be
retried, and sends an operator hunting a capability bug instead of a packaging
one. A throw from create_task_session is now a plain runtime_error, so it maps
to INTERNAL. Only a null return, where the family genuinely declined, stays a
CapabilityError.

The model.'s task: option was parsed and then dropped: it lived in a local that
died at the end of LoadModel and had no route to RequestShape::pinned_task.
LoadedModel now keeps it and exposes pinned_task().

The global model becomes a shared_ptr reached through snapshot(). An audio RPC
runs for seconds and cannot hold g_model_mu for its duration, so under a
unique_ptr a Free arriving mid-request would destroy the model underneath it.
Handlers now take a counted reference and whichever finishes last does the
teardown, outside the lock.

session_for documents the streaming state contract rather than resetting the
session itself. Resetting on a cache hit was tried first and is not possible:
silero_vad throws 'session prepare() must be called before Silero VAD reset()',
so it would turn an ordinary second fetch into a hard error. start_stream's base
implementation is already a reset, so a caller that runs prepare then
start_stream per stream gets a clean session; a probe against the bundled
silero_vad confirms an identical replay when it does and a carried-over stream
when it does not.

Also: an unknown backend: name is rejected before the model loads rather than
after; MainGPU is parsed instead of passed through std::atoi, which turned
'gpu1' into device 0 silently; and device carries a device_set flag, because 0
is both the default and a real device index, so MainGPU was overriding an
explicit device:0 that the neighbouring threads: handling promises will win.

* backend(audio-cpp): serve the VAD and Diarize RPCs

Both emit float seconds, converted from the runtime's sample-index spans, and
both take a counted reference to the loaded model through snapshot() and hold it
for the whole call: a Free arriving mid-request drops only the global's
reference, so whichever request finishes last destroys the model instead of one
of them running on freed weights. An AddressSanitizer build reproduces exactly
that heap-use-after-free inside ggml_vec_dot_f32 when the handler keeps a raw
pointer instead, which is why the shape is what it is.

The inference lane is taken before session_for, not after. session_for reads and
writes an unsynchronised session cache and the offline run calls prepare(),
which mutates the session, so both belong inside the lane.

Diarize routes before it reads the input file, so a family that cannot diarize
at all says so rather than complaining about the audio first. Its per-segment
text stays empty because audio.cpp's SpeakerTurn carries a span and a speaker
label only, and nested or overlapping turns are passed through untouched: a
sortformer turn inside another speaker's turn is correct output for overlapped
speech, and LocalAI is overlap-tolerant downstream. Duration counts frames
rather than floats, so a stereo input does not report twice its length.

Verified end to end against upstream's bundled silero_vad, which needs no
download, using the bundled 16 kHz speech asset: a synthetic tone returns
nothing, correctly, because silero detects speech and a sine is not speech.

* backend(audio-cpp): enforce ModelIdentity on VAD and Diarize

audio-cpp was the only C++ backend without the model-identity guard, and no
later task in the plan added it. pkg/grpc/server.go enforces checkModelIdentity
on exactly these two RPCs, for the reason #10952 records: in distributed mode a
worker can recycle a stopped backend's gRPC port for another model's backend,
and the controller's liveness-only probe cannot tell a stale cached route from a
live one. Without this guard a stale route gets a different model's VAD or
diarization answer back with a 200.

The loaded identity lives on LoadedModel rather than in a separate global, which
is where this differs from llama-cpp. A handler holding the model through
snapshot() then necessarily judges against the identity that model was loaded
with, and a concurrent reload cannot swap one without the other. The refusal is
NOT_FOUND carrying the verbatim grpcerrors.ModelMismatchSentinel substring.

session_for and run_offline now take a const LaneEntry & proof-of-holding
parameter. The rule that both must run under the inference lane was prose, which
is exactly how the plan came to specify the inverted order; it is now a compile
error. Restoring the inverted order fails to build rather than racing on an
unsynchronised session map with a mutating prepare().

Diarize's speaker-hint comment claimed the dropped hints were "not a silent
failure". From the caller's side that is what they are, and backend.proto
documents num_speakers as forcing, so the comment now says plainly that the
forwarding is dead for sortformer and that the family which lands must either
honour num_speakers or refuse it. read_audio_file inspects the error_code from
exists(), so an unsearchable parent directory no longer reports as a missing
file. The VAD handler records the stimulus that actually works, since silero
correctly ignores synthetic tones and the next task would otherwise rediscover
that.

* backend(audio-cpp): make the lane and identity guards structural

Two hardenings ahead of the eleven handlers still to be written, both of which
get harder to retrofit later.

The lane proof-of-holding parameter was a const reference, which binds to a
temporary, so session_for(rpc, shape, model->acquire(0)) compiled. Each such
temporary dies at the end of its own full-expression, releasing the lane between
two calls that must share one: precisely the split the parameter exists to
prevent, and the form a future author is most likely to reach for because it
reads as tidy. A non-const reference requires an lvalue, so the temporary form
now fails to compile while the named-local handlers build unchanged. The header
comment no longer implies the check is total either: it proves a lane was taken,
not that it is this model's lane.

The identity check was two lines each handler had to remember, with nothing
failing if a new one forgot them and no C++ equivalent of
model_identity_modalities_test.go to notice. snapshot() becomes
snapshot_unchecked(), whose only legitimate caller is Status, since HealthMessage
carries no ModelIdentity. Handlers go through snapshot_for(), which takes the
counted reference, refuses when nothing is loaded, and runs the identity check
before anything can route. Every handler already has to call something to obtain
the model, so the guarded call is now the shortest path and skipping it means
deliberately typing snapshot_unchecked. A convention that has to be remembered
can rot; this cannot.

Verified: the temporary-argument and inverted-order forms each fail to compile
with the expected diagnostic, the real handlers build, and bypassing the guard in
Diarize alone turns the identity test red on that RPC while VAD stays green.

* backend(audio-cpp): serve the AudioTranscription RPC

Adds result_map, the engine-to-proto boundary, and wires the offline
transcription RPC.

The handler branches on the ROUTED task: for Asr the request's prompt is
whisper-style decoding context and becomes a request option, for Alignment
the same field IS the transcript to align and becomes the text input.
Routing has already decided which.

The result text is TaskResult.text_output verbatim and is never derived
from the segments. audio.cpp carries transcript text in text_output and
nowhere else, so deriving it returns an empty transcript for every
producer that reports segments without word timing. transcript_assembly
already enforces that; this commit's job is not to undo it at the proto
boundary, and result_map_ctest pins it there.

read_audio_file now takes the sample rate the caller needs. Both file-fed
speech handlers ask for 16 kHz mono, for two reasons: silero_vad and
sortformer_diar refuse anything else outright, which turned an ordinary
44.1 kHz upload into INTERNAL, and nemotron_asr emits word timestamps in
its own 16 kHz feature domain whatever the input was, so only a 16 kHz
buffer makes the emitted nanoseconds right. Zero keeps the file's native
rate and channels, which is what source separation will need.

LoadedModel::check_can_serve answers a capability refusal before the lane
is taken and before the input file is read. Routing is a pure read of the
immutable capabilities, so a model that cannot serve an RPC no longer
waits out somebody else's run to say so. VAD and Diarize use it too.

* backend(audio-cpp): stop linking sentencepiece's vendored protobuf

engine_runtime links sentencepiece, whose default SPM_PROTOBUF_PROVIDER
builds the protobuf-lite 3.14.0 sources it vendors. The generated
backend.pb.cc is built against the toolchain's protobuf 3.21.12. Both
ended up in the binary: 476 google::protobuf:: symbols came from the
archive, 278 of them also defined by libprotobuf.so, and the archive won,
because once ld pulls a member in for sentencepiece's own code every
reference binds to the definitions that member carries.

The visible symptom is one function.
ParseContext::ParseMessage(MessageLite*, const char*) is what a generated
_InternalParse calls for a submessage field and for nothing else, so flat
messages parsed and nested ones did not: a TranscriptResult carrying
segments serialized to correct bytes that the same process could not read
back, and TranscriptLiveRequest, a oneof of submessages, could not have
been parsed at all. Underneath that, 3.21 generated code was running 3.14
arena, ArenaStringPtr and ExtensionSet code.

-Wl,--exclude-libs does not fix it. It makes those symbols LOCAL in
.dynsym and the parse still fails, because the binding was decided at
static link time and no visibility flag revisits it.

Setting SPM_PROTOBUF_PROVIDER to "package" before add_subdirectory points
sentencepiece at the protobuf the generated code was already built
against. Zero google::protobuf:: definitions remain in the executable
afterwards, every nested message round trips, and citrinet_asr, which
parses a SentencePiece ModelProto at load time and would break first if
this were wrong, still tokenizes and transcribes correctly.

* backend(audio-cpp): fix the segment text a transcription response is built from

Segment text is not decoration. core/http/endpoints/openai/transcription.go
routes response_format text, srt, vtt and lrc through
schema.TranscriptionResponse, which builds the entire body out of
Segments[].Text and never reads the top-level text. So for those four
formats the segment text IS the response.

nemotron_asr emits one word_timestamp per SentencePiece token, and the
word boundary is carried as a LEADING SPACE on the piece ("So", "me",
" call"). join_words inserted a space unconditionally, so
response_format=text returned "So me  call   me  na ture ," while the
correct sentence sat unread in the top-level field. The separator is now
chosen from the words themselves: whole words are space-joined, subword
pieces are concatenated, and one leading space anywhere selects the
latter. Concatenating the real nemotron pieces reproduces text_output
exactly, verified end to end.

This does not touch the top-level text, which is still text_output
verbatim. The rule that forbids deriving the transcript from the segments
is about the direction segments -> text; segment text has no source other
than its words.

Two smaller corrections in the same area:

timestamp_granularities ["word"] set only "word_timestamps", a key no
family in the pinned upstream reads. It now sets "return_timestamps",
which qwen3_asr does read and which both runs its forced aligner and
shortens its chunk window, so asking for word granularity no longer
silently returns nothing.

The request-option comment claimed more than it delivered. prompt,
translate and temperature are read by no ASR family, and are forwarded
only so a family adopting them works unchanged; the comment now says so
per key, and gives TranscriptRequest.diarize the same explicit treatment
threads already had.

Also: the shipping target now carries -Wall -Wextra -Wpedantic, which it
never did, so "the build is clean" starts meaning something; and
fill_transcript_result no longer swallows a null response pointer, since
answering OK with an empty transcript is the one failure mode this unit
exists to prevent.

* backend(audio-cpp): serve the AudioTransform RPC

Covers voice conversion, singing voice conversion, speech to speech and source
separation, the four tasks LocalAI's AudioTransform can represent.

AudioTransformResult carries one dst while htdemucs and mel_band_roformer
produce several named stems from a single run, so inference runs ONCE, every
stem is written as a sibling file <dst-stem>.<name>.<ext>, and params[stem]
selects which one dst receives, defaulting to vocals and falling back to the
first output. An unknown stem name is INVALID_ARGUMENT listing the real stem
names rather than a silent substitution, and the selection happens before the
first write so a refused request leaves no files behind. params[stem] is
consumed here and is not forwarded into the engine's request options.

The stem decision lives in stem_selection, which is stdlib only and therefore
tested by backend/cpp/run-unit-tests.sh. It also validates the names, because
they come from the model (htdemucs reads them from the GGUF's config.sources)
and each becomes a component of a path this backend writes: a name carrying a
path separator would escape the caller's output directory, and two stems
sharing a name would silently overwrite one another.

Both files are read at their native rate and channel count. Separation forces
it, since demucs and roformer refuse any rate but 44.1 kHz and lose the stereo
image that separates a centred vocal from a wide mix. The conversion families
all resample internally (seed_vc, vevo2, miocodec, chatterbox were each
checked), so passing the file through unchanged is also strictly better than
band limiting it to 16 kHz first.

Verified end to end against htdemucs f16 on a 44.1 kHz stereo mix: four stems
plus dst, dst byte identical to the selected stem, params[stem] selecting a
different one, an unknown stem refused with no files written, and mono input
preserved as mono output. Also against miocodec for the single output path,
where params[stem] is refused rather than ignored.

* backend(audio-cpp): refuse an impossible stem early, and stop blaming the caller for a failed write

Four fixes from the first review of the AudioTransform RPC.

check_can_serve now returns the resolved route, so params[stem] on a route that
is not source separation is refused from the route instead of after a full
inference: 11 ms rather than the 4.5 s a miocodec conversion costs, and far
worse on seed_vc or vevo2. The post-run refusal stays as the backstop for a
separation-routed family that returns no stems anyway. The typo'd-stem-name
case still needs the run, since no framework header publishes the stem names
before one.

Stem names carrying control bytes are refused. GGUF strings are length prefixed
and demucs reads its sources from JSON, so an embedded NUL survives to here:
two names differing only after the NUL are distinct std::strings, so the
duplicate check passes them, and then path::c_str() truncates both and they
open the same file. That is exactly the silent overwrite the duplicate check
exists to prevent, with the .wav lost as well.

A failed write is now INTERNAL rather than INVALID_ARGUMENT. The destination is
LocalAI's own generated-content directory, not anything the caller named, so a
full disk or a permission fault there is a server fault and is worth retrying,
which is the opposite of what INVALID_ARGUMENT tells a client. An empty output
path stays INVALID_ARGUMENT.

Two comment corrections and one clarification: the separators' required rate is
their checkpoint's declared samplerate rather than a hardcoded 44100, seed_vc
resamples with soxr and falls back to sinc-hann, and the "no files left behind"
guarantee covers a refused request, not a write that fails partway through the
loop.

* feat(audio-transform): stop folding every upload to 16 kHz mono, and name the separation stems

Two defects that made source separation unusable through LocalAI's own API,
even though the backend served it correctly over gRPC.

/audio/transform normalized every upload to 16 kHz mono s16 through
utils.AudioToWav, with no way past it. htdemucs and mel_band_roformer refuse
any rate but their checkpoint's own and separate a centred vocal from a wide
mix using the stereo image, so every separation request through the HTTP API
died with "HTDemucs prepare() sample rate mismatch: expected 44100, got 16000"
while the same call over gRPC worked. The fold is not wrong, it is
backend-specific: LocalVQE's echo cancellation genuinely wants 16 kHz mono and
needs the reference in the same shape. So it becomes a declaration,
BackendCapability.AudioTransformInputMono16k, set for localvqe and for nothing
else. A backend that declares nothing gets its upload unchanged, which means no
backend has to opt in to work. utils.AudioToWavPreservingShape is the
non-folding conversion: a 16-bit PCM WAV passes through byte for byte at any
rate and channel count, anything else is transcoded to WAV with its rate and
channel layout kept.

The other defect is that the run-once stem design bought nothing. A separation
backend writes every stem beside dst from one inference, but AudioTransformResult
carried only dst, so the other three were files no caller could find and a
caller wanting all four had to run four separations. AudioTransformResult grows
a repeated AudioTransformStem, the backend fills it, core/backend validates that
each path really is inside the generated-content directory it handed over, and
the endpoint publishes them as an X-Audio-Stems JSON header beside the existing
X-Audio-Input-Url. JSON because a stem name is the model's own string and could
contain any separator a hand-rolled format would use.

Verified end to end through the HTTP endpoint with htdemucs f16 on a 44.1 kHz
stereo file: 200 with a 44.1 kHz stereo body, all four stems named and fetchable
through /generated-audio/, body byte identical to the selected stem, and
params[stem]=drums returning a different one. The same upload sent to a model
whose backend is localvqe still reaches the backend as 16 kHz mono, confirmed
both by the engine's own rate refusal and by the persisted input file.

* fix(audio-transform): reject extensible WAV from the passthrough, escape stem URLs, convert stems with dst

Four fixes from the second review, plus one bug they made visible.

isPCM16Wav tested only the bit depth, and go-audio's IsValidFile never looks at
the format tag, so a 16-bit WAVE_FORMAT_EXTENSIBLE (0xFFFE) upload was passed
through untouched where the old fold would have transcoded it. audio.cpp's WAV
reader accepts 16-bit only when the tag is 1, so such a file died with
"unsupported WAV encoding". Extensible is what many DAWs and Windows tools
write and music files are this endpoint's new headline input, so it is a
first-contact failure rather than a corner. The check now requires tag 1, with a
spec that fails against the old implementation.

Stem URLs are percent-escaped. A stem name is the model's own string and legally
contains a space, a '#', a '?' or a '%'; an unescaped '#' truncates the URL
before the request is even sent. The name field keeps the raw name.

sample_rate and response_format are applied to the stems as well as to dst.
Applying beat documenting: dst IS one of those stems, so leaving them alone
broke the "dst duplicates the selected stem" invariant the whole design rests
on, and both conversions are no-ops when unset. A stem whose conversion fails is
dropped from the header rather than advertised in the wrong shape.

Verifying that turned up why it had never been noticed: the two fields were
never bound at all. The request arrives as multipart/form-data and echo's binder
falls back to the FIELD NAME without a form tag, matching only
case-insensitively, so "SampleRate" never matched "sample_rate" and "Format"
never matched "response_format". Both were documented in the endpoint table and
silently ignored. Two form tags fix it, and with them the conversion is
observable end to end.

Docs: audio-transform.md now documents what LocalAI does to an upload before the
backend sees it, which backend gets the 16 kHz mono fold and why, params[stem],
and the X-Audio-Stems header with a worked example.

Also records the known limitation that the fold lookup is on the bare backend
name, so pinned variants (vulkan-localvqe) do not match, and points at
IsLlamaCppBackend as the suffix-tolerant precedent.

* backend(audio-cpp): serve the TTS and SoundGeneration RPCs

TTSRequest.voice is treated as a speaker reference clip when it names an
existing regular file, which makes routing prefer VoiceCloning, and as a named
preset otherwise, in which case it travels as VoiceReference::cached_voice_id.
Both the clip and SoundGenerationRequest.src are read at the file's own rate and
channel count: upstream's own CLI and server do exactly that, every consuming
family resamples internally and mostly with a better resampler than ours, and
ace_step and stable_audio resample their input per channel, so a downmix here
would delete the stereo image they are built to consume.

The request builders live in their own unit rather than in grpc-server.cpp's
anonymous namespace so they can be tested; grpc-server.cpp has a main() and
cannot be linked into a test binary. The option keys are the whole point of
these functions, so each one was grepped against the pinned upstream and the
accounting is written down beside it. instructions maps to "instruct", which is
what upstream's own server maps the OpenAI field to and what qwen3_tts and
omnivoice read, and to "caption" for irodori_tts; the style tag is spelled
"instruct" too, because "instructions" is looked up nowhere. duration maps to
"duration_seconds", read by all three generation families, with the proto's own
name kept only as a forward-tolerant alias. Keys that no family reads say so.

Both handlers answer a capability refusal before taking the lane and before any
file read, so a model that cannot synthesise does not queue behind somebody
else's run to be told no.

* backend(audio-cpp): stop emitting an empty style language, and name the missing clip

StyleCondition::language was set whenever has_language() was true, with no
!empty() guard, while the language option twelve lines below had one.
core/backend/tts.go sets Language unconditionally, so has_language() is true on
every request LocalAI sends and carries "" when the caller named none. An
engaged-but-empty style language is worse than an absent one: supertonic reads
text_input->language behind its own !empty() guard and then overrides it from
style->language with no guard at all, so "" replaced its "en" default and its
tokenizer threw "invalid Supertonic language: ". Every /v1/audio/speech request
that set instructions and no language would have been an INTERNAL against a
supertonic model. A plain request never saw it, because the style condition only
exists when instructions are non-empty, which is why the chatterbox end to end
run did not catch it.

TTS also stops discarding the Route that check_can_serve already returns. A
family routed to voice cloning without a reference clip used to be refused from
inside its own prepare(), which meant an INTERNAL naming neither the RPC nor the
field to set; chatterbox advertises clon and no tts, so that was every
preset-only request to it. It is now an INVALID_ARGUMENT naming
TTSRequest.voice, answered in about 4 ms, and it cannot misfire because
has_voice_reference is what selected cloning in the first place. Reading
CapabilitySet::supports_speaker_reference to generalise this stays a follow-up.

The src read carries a written caveat rather than a family blocklist, because
ace_step's editing routes legitimately need src: setting src on a stable_audio
model corrupts the heap and aborts the process in the pinned upstream, and the
only thing keeping that off the network is that
schema.ElevenLabsSoundGenerationRequest has no field for it. Nobody reading that
Go schema would know why, so the reason is recorded where the field is read.

build_tts_shape is extracted so TTSStream cannot describe the same request
differently, and it arrived untested: two mutations of it survived until a
test_tts_shape case was added.

* backend(audio-cpp): serve the TTSStream and AudioTranscriptionStream RPCs

TTSStream leads with a streaming WAV header carrying 0xFFFFFFFF sizes, matching
the convention backend/go/vibevoice-cpp established, so an HTTP client can start
playback before the full PCM exists. Its chunks are read from
StreamEvent::named_audio_outputs and not audio_output: supertonic, omnivoice and
voxcpm2 all put their streamed audio there and leave audio_output empty until
the very end, so reading the obvious field yields a stream with no audio in it.
The finish_stream result is the family's own merged whole rather than a tail, so
it is emitted only when nothing was streamed.

Streaming transcription sends incremental deltas and degrades to a single delta
plus the final result on families that offer no streaming ASR, which is the same
message sequence with fewer deltas. The four streaming ASR families disagree on
what partial_text means: nemotron_asr, vibevoice_asr and higgs_audio_stt report
incremental fragments while voxtral_realtime reports the whole hypothesis and
reports it twice, so the reconciliation lives in one tested unit rather than in
the handler. nemotron_asr reports only through the stream event sink, and only
from inside finalize, so the audio driver installs one and clears it again
before returning: the session is cached and a sink left holding the caller's
frame is a use after free waiting for the next stream.

begin_stream is now the only implementation of the streaming state obligation,
prepare then start_stream. Streaming sessions are cached, and what clears the
previous stream is start_stream's reset; a family override that dropped it would
break every call site with no compile error, so there is one call site.

* backend(audio-cpp): keep streaming deltas on UTF-8 boundaries, refuse dtypes that abort

TranscriptStreamResponse.delta is a proto3 string, whose wire format requires
valid UTF-8. voxtral_realtime reports its hypothesis as a concatenation of raw
token BYTES (tokenizer_text.cpp:171-183), so the cumulative difference between
two consecutive reports is eventually a lone continuation byte, and the C++
runtime serializes that with only a logged warning while the Go runtime refuses
to unmarshal it: the client loses the remaining deltas AND the final_result.
Measured on a trace of a non-ASCII sentence, 11 of 31 messages failed to
unmarshal and every accented character was lost. TranscriptDeltaTracker now
holds back an incomplete trailing sequence and merges it into the next fragment;
reconcile flushes it, which it always can because the final text is complete.
The same trace now unmarshals in full with zero failures.

A streaming buffer whose float count is not a whole number of frames is refused
rather than truncated. The integer division dropped the tail floats from the fed
audio and therefore from the transcript, with no diagnostic; vibevoice_asr
refuses the same thing from the other side of the call.

A supertonic GGUF whose weights are not f32 is refused at load. It reaches
ggml_concat with mismatched operand types and ggml_abort takes the whole backend
process down on the first request, so nothing downstream can report it: the
model loads, then every request kills the process. Attributed rather than
assumed, the unary TTS path aborts identically, and upstream records that
package as untested. The refusal names the orig package and says what to run
before deleting the guard.

* backend(audio-cpp): stop a repeated lead byte from orphaning the next delta

The first UTF-8 fix closed the cumulative half only. Rule 2 discards a fragment
the known text already starts with, and when that fragment is the LEAD BYTE of a
new character it looks exactly like a repeat of an older character beginning
with the same byte. It was discarded rather than held, its continuation bytes
then arrived alone and began the next delta, and utf8_complete_prefix_length
only ever inspected the trailing sequence, so a delta invalid at the FRONT went
out whole. Through a real Go proto.Unmarshal the review's four-character repro
gave 3 deltas, 2 unmarshal failures and a lost transcript.

Reachable from the incremental families, not only from voxtral: nemotron_asr's
decoder cuts at a byte offset and vibevoice_asr's common_prefix_size compares
bytes, so both split characters. Measured over 30,000 randomized incremental
traces, 53.28% of Japanese traces and 9.52% of French ones carried at least one
delta the Go runtime refuses.

Two changes. Rule 2 no longer judges a fragment that ends mid-character, so the
lead byte is held instead of swallowed and the character survives intact; the
cost is a few duplicated bytes in a shrinking cumulative report, which no pinned
family produces. release() additionally drops leading orphan continuation bytes,
so no delta can begin mid-character whatever the rules above it decide. Losing a
byte keeps the stream alive; emitting one ends the RPC and takes the
final_result with it.

Post-fix all 60,000 traces produce zero unmarshal failures, and the cumulative
streams plus both pure-ASCII incremental streams are byte-identical to the
previous commit, so nothing changed for the families already working.

The weight-dtype allow list moves to family_gate, where it is stdlib-only and
pinned by a test rather than only by a comment. Two comment citations corrected.

* backend(audio-cpp): read only an exact repeat as a repeat, not any prefix

Rule 2 discarded any partial the known text merely started with. For a cumulative
family that is a duplicate; for an incremental family it is an ordinary short
fragment that happens to coincide with the start of the transcript, and it was
dropped, silently corrupting the text. Pure ASCII, no multi-byte character
anywhere: the fragments "pure ", "ascii ", "trans", "c", "ri", "p", "t" left the
client holding "pure ascii transcrit". Over 5,000 randomized traces per
transcript, 9.50% of pure-ASCII and 29.12% of French traces ended with the client
holding something other than final_result.text, with a 200 and no diagnostic.
Both incremental families emit fragments that small routinely, since nemotron_asr
cuts at a byte offset and vibevoice_asr at a common prefix.

Narrowing rule 2 to an exact repeat drives that to zero on all six transcripts
and changes no cumulative stream at all: 30,000 randomized cumulative traces are
byte-identical to the previous commit.

What rule 2 guarded was established from upstream rather than from its own
comment. The only duplicate any pinned family produces is voxtral_realtime's,
where process_available_stream_chunks feeds each event to the sink from inside
its loop and returns the last of the batch, so that event arrives twice with
byte-equal text. A duplicate is an exact repeat, so equality still covers it. The
case given up is a cumulative report that SHRINKS, which no pinned family can
produce: voxtral decodes a token vector that is only push_back'ed and cleared by
reset(), so within a stream it can only grow.

* backend(audio-cpp): serve the AudioTranscriptionLive RPC

The one bidirectional stream this backend serves. The client sends a
TranscriptLiveConfig, then TranscriptLiveAudio frames; the server acknowledges
with ready, emits deltas as the audio arrives, and sends final_result once the
read side closes. There is no offline fallback: live transcription has to
consume audio incrementally, so a family with no streaming ASR is refused
rather than served a batch run, which is what this RPC's Streaming-only
mode_candidates list already says.

The driver is a new sibling of run_streaming_audio, run_streaming_live, because
the audio does not exist yet: instead of slicing a buffer it pulls frames from
the caller until the read side closes. It installs the same ScopedStreamSink in
the same order, which is not optional, since nemotron_asr returns a bare event
from process_audio_chunk and reports every partial through the sink from inside
finalize(). It buffers the wire's frames up to the family's own preferred window
rather than feeding whatever size the client's audio callback produced, and it
does not call finish_stream at all when no audio arrived, because nemotron_asr
throws "finalize requires streamed audio" and an empty transcript is the
truthful answer to transcribing nothing.

Three things the handler had to get right and one it cannot:

  - The audio contract. A live request carries no samples, but nemotron_asr's
    streaming prepare() throws without an audio contract, and
    build_preparation_request derives it from TaskRequest::audio_input, so that
    field is an EMPTY buffer holding only the rate and the channel count.
  - 16 kHz or a refusal. The families express their spans in their own 16 kHz
    feature domain whatever the input was, and live frames cannot be resampled
    on the way in the way a file can, so an 8 kHz session would return
    timestamps 2x off with a 200. core/backend hardcodes 16000 anyway.
  - A mid-stream Config is refused. backend.proto calls it a decoder reset, but
    deltas already on the wire cannot be retracted, so a reset would leave the
    final text contradicting the transcript the client assembled. Ignoring the
    message would hand a client that believes it reset the decoder a transcript
    that silently continues the audio it thought it discarded.
  - The stale-route identity check cannot run here: TranscriptLiveRequest
    carries no ModelIdentity in either arm of its oneof, so snapshot_for does
    not instantiate for it. snapshot_unchecked's comment now names that as a
    second legitimate class of caller and says the fix is a proto change.

eou and eob stay false. They exist for cache-aware models that emit
end-of-utterance and end-of-backchannel tokens; audio.cpp's StreamEvent has no
equivalent signal, and a client uses eou to decide the speaker yielded the turn,
so a guess inferred from silence cuts people off mid-sentence.

The lane is held for the whole stream, which is as long as the user keeps
talking: the streaming session is stateful and cached, so a concurrent run would
interleave two callers' audio and corrupt both transcripts.

Verified against nemotron_asr over a real connection with a 14 s WAV in
512-sample frames: ready first, 59 incremental deltas with no repeated prefix,
concat(deltas) equal to final_result.text, word timestamps in nanoseconds, eou
and eob false. citrinet_asr answers UNIMPLEMENTED naming the family and listing
asr/offline. A config followed by a close returns an empty final_result rather
than hanging, and a first message that is not a config is INVALID_ARGUMENT. Two
concurrent streams both return the complete transcript.

Two cleanups on lines Task 12 touched, folded in. The DtypeAllowList terminator
is now asserted at compile time: the reported out-of-bounds read did not exist,
the single entry does terminate, but the loops have no other bound and any edit
that widened an entry would walk off the end. And the dtype guard now
short-circuits on "is there a table entry" through a new predicate rather than
on the emptiness of the description string, which would have skipped the check
on an entry with an empty allow list, i.e. on precisely the entry that refuses
every dtype.

* backend(audio-cpp): bound the lane a live stream can hold

AudioTranscriptionLive holds the model's inference lane for the whole stream,
which is correct (the streaming session is stateful and a concurrent run would
interleave two callers' audio) and newly dangerous. Every other RPC holds the
lane across compute, or across a write to a slow reader, and both of those
terminate on their own. A live stream instead blocks in a client-driven read,
and a peer that goes silent WITHOUT closing the stream never terminates
anything: the lane stays taken and every other request against that model queues
behind a client that stopped speaking.

live_watchdog is a one-shot idle timer that ends the stream when no frame has
arrived inside a window. It is standard library only, so it is unit tested
without an engine. gRPC's synchronous Read has no timeout and cannot be given
one, so the only way to unblock it is ServerContext::TryCancel, which decides
the wire status itself: the client sees CANCELLED rather than the
DEADLINE_EXCEEDED the handler returns, the reason is logged, and the lane coming
back is the point. When it fires the read loop throws rather than reporting
end-of-input, so the driver does not go on to finalize a decode nobody is
waiting for.

It is armed only after the lane is taken and disarmed as soon as the read side
closes, and both ends matter. Arming earlier would cover acquire(), which
legitimately blocks while another live stream runs, so a queued caller would be
cancelled for waiting its turn. Disarming later would cover our own decode,
where a window overrun is not a peer going quiet and cancelling would throw away
the transcript the client is waiting for.

The window is the new live_idle_timeout_ms option, 30 s by default, 0 meaning no
limit. core/http/endpoints/openai/realtime.go drives a 300 ms ticker and feeds
every tick that produced new audio while a turn is open, so 30 s of silence is a
hundred ticks that delivered nothing. It is also longer than any pause a speaker
takes mid-utterance, which is the case that must never be cut off, and
backend.proto lets one stream span many utterances, so a client that pauses
longer between them raises the option rather than discovering it.

Two smaller corrections in the same handler:

  - check_can_serve now runs BEFORE the sample rate check.
    pkg/grpc/grpcerrors/errors.go degrades to the file path on UNIMPLEMENTED and
    on nothing else, so a live-incapable model asked at a wrong rate was
    answering INVALID_ARGUMENT and costing the caller its fallback.
  - a negative sample rate is refused instead of silently becoming 16000. Zero
    still means 16000, which is what the proto documents; -1 is malformed rather
    than absent and gets the same refusal every other bad rate gets.

And one thing recorded rather than changed, at the handler: "live" here means
incremental INPUT, not low latency, and with the pinned families it does not yet
mean incremental OUTPUT either. nemotron_asr's process_audio_chunk only appends
to its buffer, so its whole decode and every delta happen inside finalize(),
after the client closes its send side. The policy-window buffering is inert for
that family and matters only for vibevoice_asr and higgs_audio_stt.

Verified on the wire with live_idle_timeout_ms:3000. A silent client acked at
371 ms and was cancelled at 3.371 s; a second live stream opened one second
later received its ack 2.37 s in, i.e. at the instant the first was cancelled,
and then transcribed successfully on the same cached session. Without the
watchdog it would still be waiting. Re-ran the live transcription (ready first,
59 incremental deltas, concat equal to the final text, word timestamps in
nanoseconds, eou and eob false), the citrinet refusal at both a right and a
wrong rate (UNIMPLEMENTED either way now), and Task 12's AudioTranscriptionStream
on nemotron_asr, which is unchanged.

Mutation testing the watchdog found a weakness in its own test: the destructor
test slept past the window inside the watched scope, so a destructor that
DETACHED the thread instead of joining it passed unnoticed. The test now uses a
window longer than the scope, which kills that mutant, and says why.

* backend(audio-cpp): refuse the unsupported RPCs with a reason

AudioEncode, AudioDecode, AudioTransformStream, AudioToAudioStream and
VoiceEmbed have no counterpart in audio.cpp's VoiceTaskKind. Each now returns
UNIMPLEMENTED naming the loaded family, what that family does support, and the
upstream limitation, instead of the generated base class's bare status. The
reasons live in a table in capability_routing.cpp so they are data rather than
literals copied into five handlers, and so a test can assert every one of them.

The five claims this was planned against were re-read at the pinned upstream
e800d435d130dc776baf6f3e6129bb62b1495c89, and one did not hold. "audio.cpp
streams tts and asr only" is false: silero_vad advertises vad with
RunMode::Streaming. The refusal stands on the narrower claim that survives, that
no family advertises streaming for any task AudioTransform routes to, and a test
asserts the refuted wording does not come back.

VoiceEmbed is the one refusal whose request carries a ModelIdentity, so it runs
the #10952 check before answering: a stale route must get NOT_FOUND and the
router's sentinel, not "audio.cpp cannot embed speakers" about a model that is
not loaded here. It cannot use snapshot_for, whose no-model branch would tell
the caller to load a model when no model can help, so it takes the reference
through snapshot_unchecked and checks identity itself. That function's comment
now names three classes of caller instead of two.

The two bidirectional surfaces refuse without reading their stream, verified
with a client that writes a config and eight frames first and gets the status
rather than hanging.

* backend(audio-cpp): correct the vevo2 clause, and assert the absences

Review found a false clause in the AudioToAudioStream refusal. It said s2s is
"offline voice conversion ... which converts one clip into another speaker's
voice", which is true of miocodec and false of vevo2: vevo2's s2s route is
`editing` and only `editing` (default_route_for_task and route_matches_task in
src/models/vevo2/session.cpp), documented as "Edit source speech into new target
text while using the target voice" and requiring --target-text, so it rewrites
what was said. vevo2's voice conversion is its separate vc task. It now reads
"offline clip-to-clip processing against a target voice, declared only by
miocodec (voice conversion) and vevo2 (speech editing)", and a test asserts the
miscast cannot come back. The conclusion is unchanged: neither family converses.

That defect was undetectable on the wire, since vevo2 does not load here, which
is the argument for upstream_absence_ctest.cpp. It links engine_runtime purely
to interrogate make_default_registry() and asserts the five premises the refusal
reasons rest on: no codec task kind, no family advertising spk, no streaming for
sep/vc/svc/s2s, miocodec advertising exactly vc and s2s, and s2s advertised by
exactly miocodec and vevo2. The last two are exact sets, so an addition fails
here rather than leaving a message stale. A positive control proves the registry
is populated and the query works before any absence is believed, and every
assertion has a reproduced negative control. This turns an AUDIO_CPP_VERSION
bump from "remember to re-read five prose paragraphs" into a test failure.

unsupported_surface now switches over UnsupportedRpc with no default label, so
-Wswitch reports a sixth enumerator added without a row at build time; the
runtime bounds guard it replaces is deleted.

The AudioTransformStream reason had a true premise and an overreaching
conclusion: an offline sep family could be buffered into a stream, as other
LocalAI backends do. It now says this backend declines to offer a buffered
offline call in disguise, rather than implying impossibility.

* backend(audio-cpp): make the missing-switch-case diagnostic fatal

unsupported_surface() switches UnsupportedRpc onto the table row that explains
it, with no default label, so -Wswitch reports an enumerator nobody handled. As
a warning that is not enough: adding a sixth enumerator and building the shipping
target gives exit 0, a binary and one warning, and the trailing
`return surfaces[0];` then answers the new RPC with AudioEncode's codec reason.
That is a confident, specific and false statement about audio.cpp on the wire, on
the one code path whose entire job is to be truthful about what this backend
cannot do, and it is worse than the runtime fallback it replaced, which at least
named itself as a bug in this file.

capability_routing.cpp therefore joins loaded_model.cpp on the existing
-Werror=switch pin, whose comment already made this argument for the engine enum.
The comment now covers both files. The pin stays per-file rather than
project-wide because upstream's own ace_step/vae_decoder.cpp has unhandled
-Wswitch cases of its own.

Verified: a sixth enumerator now fails `make grpc-server` with exit 2 and no
binary; appending a 14th VoiceTaskKind upstream still fails loaded_model.cpp, so
the two pins fire independently; both reverted clean.

* backend(audio-cpp): package the backend image

Bundles the dependency closure for the from-scratch image, the dlopened ggml
CPU-variant shared objects that ldd cannot see, and upstream's bundled
silero_vad and marblenet_vad assets so VAD works with no download.

The bundled loader sits in the package ROOT rather than at lib/ld.so. run.sh
execs it, which makes /proc/self/exe name the loader, and this backend has two
consumers of that path: ggml discovers the libggml-cpu-*.so by listing
dirname(/proc/self/exe), and resolve_model_path expands bundled:<name> under the
same directory. Rooting the loader makes the binary, the ggml objects and
assets/ share the one directory all three resolution mechanisms agree on.
llama-cpp's lib/ld.so layout would need assets/ moved into lib/ as well.

The image builds against apt gRPC and protobuf, like Dockerfile.ds4 and unlike
Dockerfile.privacy-filter. The from-source gRPC that install-base-deps.sh and
the base-grpc-* images supply vendors protobuf 26, which pulls abseil into
message_lite.h; with SPM_PROTOBUF_PROVIDER=package that collides with
sentencepiece's vendored mini-abseil and every absl::internal reference becomes
ambiguous. Noble's protobuf 3.21.12 predates the abseil dependency and is the
pair every earlier verification of this backend ran against.

* backend(audio-cpp): exempt the driver libraries from the packaging gate

package.sh already left libcuda.so* and libnvidia-* to the host when copying,
because the driver has to match the kernel module on whatever host runs the
image, but the validation gate had no matching exemption. With BUILD_TYPE=cublas
ggml is static and links CUDA::cuda_driver, so grpc-server carries DT_NEEDED
libcuda.so.1 and the gate would have rejected the very absence the copy loop
created, failing every cublas build in CI. One regex now feeds both.

Building a control for that found a second defect: ld.so --list refuses to trace
an object with an unresolvable dependency at all, exiting 127 without emitting a
per-library line, so the "=> not found" rule was dead code and no exemption could
have applied to it. The gate now traces with LD_TRACE_LOADED_OBJECTS and
LD_LIBRARY_PATH, which reports the missing name and exits 0, and which is also
what run.sh does at run time.

Adds a layout assertion so a future move of the loader into lib/ fails the build
instead of shipping a package that resolves bundled: models into lib/assets and
finds no ggml CPU backend, and records for Task 16 that the Darwin script must
not be a straight copy of privacy-filter-darwin.sh, which never calls package.sh
and would silently drop assets/.

* backend(audio-cpp): register the backend with CI and the gallery

Adds the five Linux matrix entries (cpu amd64/arm64 sharing a tag-suffix so the
manifest merge fires, cuda 12, cuda 13, vulkan), the path-filter case that keeps
later PRs touching backend/cpp/audio-cpp/ from getting zero CI jobs, the
bump-bot entry pointing at the AUDIO_CPP_VERSION pin in the backend Makefile,
the gallery meta plus its -development variant and the image entries for every
variant, and the Makefile docker-build wiring.

The matrix entries carry base-image only, with no builder-base-image, unlike
the llama-cpp and privacy-filter blocks they sit next to. The prebuilt
quay.io/go-skynet/ci-cache:base-grpc-* images ship a from-source gRPC whose
protobuf v26 depends on abseil, and this backend's sentencepiece is built with
SPM_PROTOBUF_PROVIDER=package, so it sees real abseil's absl::lts_20240116::
internal alongside its own vendored plain absl::internal and every
absl::internal:: reference becomes ambiguous. Building against base-grpc-amd64
fails at sentencepiece-static.dir/error.cc.o with "reference to 'internal' is
ambiguous". Dockerfile.audio-cpp installs apt's gRPC/protobuf 3.21.12 itself,
which is also the pair every unit and end-to-end run of this backend has been
verified against, and the CUDA toolkit therefore has to come from base-image.

No Darwin matrix entry and no metal gallery entries: the Metal build needs
scripts/build/audio-cpp-darwin.sh, a backends/audio-cpp-darwin make target and
a routing step in backend_build_darwin.yml, none of which exist yet, so an
entry added now would be routed to build-darwin-go-backend and look for
backend/go/audio-cpp/. The inferBackendPathDarwin case and the
DARWIN_BESPOKE_BUILDERS membership are in place, inert, so that adding the
entry later is a one-line change that cannot be claimed by the generic Go path.

* backend(audio-cpp): pin the CUDA architectures, drop the vulkan variant

Upstream sets CUDA_ARCHITECTURES to `native` on the engine_runtime target
whenever CMAKE_CUDA_ARCHITECTURES is unset at root scope, and docs/build/
linux.md says so outright. ggml's own default does not rescue it: it
list(APPEND)s in the ggml subdirectory scope, which never reaches the root
scope where the engine_runtime property is decided. No CI runner has a GPU for
`native` to enumerate, so both cublas entries would have gone red on the very
commit that first turns a CUDA build on.

Pin the list in backend/cpp/audio-cpp/Makefile, selected by CUDA_MAJOR_VERSION,
which Dockerfile.audio-cpp now forwards from the CI build-arg it was previously
discarding. The values are copied from ggml's own version guards rather than
invented, so engine_runtime and ggml compile for the same set: CUDA 12 keeps the
Maxwell/Pascal/Volta virtual archs and stops at 120a-real, CUDA 13 drops them
and adds 121a-real. The `a` suffix is used rather than `f` because the latter
needs CMake 3.31.8 and Ubuntu Noble ships 3.28.3. Verified by driving CMake
3.28.3's own CUDA architecture validator over both lists, with 120f-virtual as
the rejected control.

Drop the vulkan matrix entry, its two gallery entries, the vulkan capability
key on both metas and the Vulkan tag. Every other vulkan backend gets its Mesa
ICD drivers from .docker/install-base-deps.sh, which package-gpu-libs.sh then
bundles; Dockerfile.audio-cpp calls neither and installs only libvulkan-dev and
glslc, so the image would ship a Vulkan loader that finds no GPU. No CI job runs
a vulkan image against real hardware, so that would have passed green and failed
in users' hands. BUILD_TYPE=vulkan stays supported for local builds.

Also note on the cublas entries that cuda-major-version now selects the
architecture list and that cuda-minor-version and the base-image tag encode the
same toolkit, and correct the stale entry counts on matrixEntryKey.

* backend(audio-cpp): build for Darwin Metal

Bespoke C++ Darwin path like ds4 and privacy-filter: an includeDarwin matrix
entry, a backends/audio-cpp-darwin make target, a gated workflow step, and the
metal image entries plus metal/metal-darwin-arm64 capability keys in the
backend gallery.

The build script deliberately does NOT reassemble the package the way
privacy-filter-darwin.sh does. It runs the backend's own `make package` and
copies the result, so the Darwin package keeps the root-level layout the Linux
one has: grpc-server, run.sh, the ggml objects and assets/ in one directory,
with lib/ for the dylib closure. Hand-assembling would drop assets/, and
assets/ is what makes the bundled: model paths resolve with nothing downloaded.
The dylib walk is a full transitive closure rather than the single level ds4
and llama-cpp do, because Homebrew's grpc++ pulls libgrpc, abseil, upb, cares
and OpenSSL that grpc-server does not link itself, and a level-1 walk ships a
package that only works on a machine that already has Homebrew grpc.

Two fixes folded in, both in the backend Makefile:

  - an EMPTY CUDA_MAJOR_VERSION fell through to the CUDA 12 architecture list,
    which contains 120a-real and so needs nvcc >= 12.8. A local
    BUILD_TYPE=cublas build on a 12.0-12.7 host failed to compile where
    upstream's documented default (native) worked. EMPTY now maps to native,
    12 and 13 keep their lists, and any other non-empty value is an error on
    cublas builds. CI always passes a major, so CI is unaffected.

  - the Darwin branch now points CMake at Homebrew's keg-only libomp. AppleClang
    ships no OpenMP runtime and nothing is symlinked into /opt/homebrew, so
    FindOpenMP finds neither the library nor the header, and audio.cpp calls
    find_package(OpenMP REQUIRED) whenever ENGINE_ENABLE_OPENMP is on. Without
    the hint the macOS build would have died at configure time. If the keg is
    absent the build disables OpenMP instead of failing.

* backend(audio-cpp): make the Darwin fallbacks loud and the rpath walk complete

Review follow-up on the Darwin Metal build.

The OpenMP fallback was silent. If brew --prefix libomp ever comes back empty,
CI produced a green Metal package with 108 #pragma omp directives across ~30
files compiled out, and clang says nothing about an ignored omp pragma without
-Wsource-uses-openmp, so the only trace was one absent flag inside a set -x
cmake line. That regression would have been blamed on Metal. It now warns.

The @rpath arm of the dylib walk had no live candidate when it was written, on
the reasoning that a Metal build links ggml statically. The OpenMP fix in the
same commit made libomp.dylib one, and whether Homebrew records it as an
absolute opt path or as @rpath/libomp.dylib is not observable from Linux. The
walk now expands @rpath, @loader_path and @executable_path against the object's
own LC_RPATH entries, and only fails when nothing on disk answers, printing the
rpath list with the error so a failure on a machine nobody can attach to
explains itself.

Also: ADDITIONAL_LIBS now go through the closure rather than a bare cp, so they
are deduplicated and their own dependencies bundled; build/darwin/lib is
created explicitly instead of relying on package.sh pre-creating it; the libomp
probe uses nested ifneq rather than $(and ...), which needs GNU make 3.81 and
would otherwise expand empty and take the OFF branch on an older make; and
-DOpenMP_ROOT is quoted like its CUDA sibling.

Verified with a Linux harness that runs the script verbatim against a stubbed
otool: a level-2 transitive dep, an @rpath dep reachable only through LC_RPATH,
and an ADDITIONAL_LIBS dep are all bundled, a dependency cycle terminates,
system libraries are skipped, the packaged tree has assets/ at the root beside
grpc-server with the dylibs in lib/, and both failure paths exit non-zero.

* backend(audio-cpp): make bundled: reachable from a model YAML

resolve_model_path() tested the bundled: prefix on `candidate`, which prefers
ModelFile and falls back to Model. LocalAI fills ModelFile by joining ModelPath
onto the configured model string (pkg/model/loader.go, LoadModelWithFile), and
only sets it from a managed artifact otherwise, so a model YAML saying
`model: bundled:silero_vad` arrives as ModelFile "/models/bundled:silero_vad"
and Model "bundled:silero_vad". The prefix therefore never matched through the
normal load path: it matched only for a hand-written LoadModel call that left
ModelFile empty, which is exactly how task 15 verified it, and every model YAML
using the form failed with "model path does not exist:
/models/bundled:silero_vad".

Both fields are now checked, Model first, so the zero-download VAD path the
package ships assets for is reachable the way it is documented. A caller that
puts the form in ModelFile still works, so task 15's verification stands.

Compiled clean; the runtime check could not run on this host, whose system
libprotobuf/libre2 have gone missing (the pre-existing grpc-server binary no
longer resolves its libraries either), so it wants a container run.

* backend(audio-cpp): advertise the backend and document its options

Registers audio-cpp as preference-only in /backends/known: the family lives in
GGUF metadata that an importer cannot read from a remote repo, and one repo
hosts thirty families, so there is no honest auto-detect signal. Modality is a
single string and the import form chips on a fixed key set, so it registers as
tts with the other modalities named in the description rather than under an
invented key the UI would bucket as "other".

Adds a features page covering the option namespacing, the routing table per
endpoint, the RPCs this backend declines and why, the bundled VAD path, the
separation stem behaviour, and the family gotchas (supertonic needs the orig
package; chatterbox advertises cloning and no plain tts; nemotron_asr defers
its whole decode to finalize so live transcription emits nothing until the
client half-closes, unlike higgs_audio_stt and voxtral_realtime). Every option
name and family capability in it was read off the pinned upstream checkout.

* backend(audio-cpp): test resolve_model_path, and correct the family names

The bundled: fix in 842443cd7 shipped without a test, which is how the bug got
there: task 15 verified the form with a hand-written LoadModel that left
ModelFile empty, and that is the one shape the server never produces. Four cases
in streaming_driver_ctest, which already links loaded_model.cpp, pin the
PRODUCTION shapes instead. The first fails against the pre-fix source (returns
the joined /models/bundled:silero_vad); the other three are the branches the
bundled: lookup now runs in front of and must fall through for.

Three family names in the docs were the source directory rather than the
registered family, on pages whose whole argument is that these names cannot be
guessed: demucs is htdemucs (demucs/loader.cpp:22), roformer is
mel_band_roformer (roformer/assets.h:15), and moss is TWO families,
moss_tts_local and moss_tts_nano. The hyphenated ASR names are underscored to
match, here and in the compatibility table.

The supertonic dtype note claimed more than the evidence carries. The f16 abort
is a local observation, identical through TTS and TTSStream; upstream's
docs/gguf.md leaves the 16-bit column untested and records q8_0 as "No
(unsupported weight dtype)", which says unusable rather than fatal. Both are
still refused, because the allow list is what the family can run. Corrected in
family_gate.h, family_gate.cpp and the docs together, since the docs inherited
the wording from the code.

The importers tripwire says in the file that it is a tripwire: it exercises no
audio-cpp behaviour, and the registration assertion lives in backend_test.go.

* gallery: add audio.cpp models covering every served RPC

One representative model per RPC group of the audio-cpp backend, plus the two
bundled VAD models, which need no download at all because the assets ship
inside the backend package.

Every hash was computed with sha256sum on the downloaded file. Quantizations
come from upstream's tested-status table in docs/gguf.md rather than a default
of q8_0: supertonic ships the orig package (its q8_0 is recorded as an
unsupported weight dtype and its f16 aborts in ggml_concat), and nemotron_asr
and htdemucs ship f16 because their q8_0 builds are recorded with drift while
16-bit is a clean pass.

Diarization and separation use the diarization and audio_transform usecases,
not transcript: /v1/audio/diarization and /audio/transform filter the default
model on FLAG_DIARIZATION and FLAG_AUDIO_TRANSFORM respectively, so a
transcript flag would have hidden both models from their own endpoints. The
forced aligner sets parameters.language, which the transcription endpoint uses
as the fallback when no language form field is sent, because the family
requires both a transcript and a language.

All ten entries were run twice: once against the raw gRPC server, and once
installed with local-ai models install and called through the HTTP endpoint.

* gallery: correct the audio.cpp entries' licenses

Swept all ten entries against the real upstream named in audio.cpp's
tools/model_manager.py rather than against the audio.cpp repo's own license.
Three were wrong:

  supertonic   apache-2.0 -> openrail      weights come from
                                           mlx-community/supertonic-3-mlx, and
                                           both it and Supertone/supertonic are
                                           openrail
  citrinet     apache-2.0 -> other         pulled from NGC
                                           nvidia/nemo/stt_en_citrinet_256,
                                           governed by the NGC Terms of Use
  sortformer   other -> cc-by-nc-4.0       nvidia/diar_sortformer_4spk-v1 is
                                           CC BY-NC 4.0, and the gallery already
                                           uses that exact string, so there is no
                                           reason to obscure a non-commercial bar

The license field is one word, so citrinet and sortformer also gained a
sentence saying why they are restricted. The other seven were confirmed
correct against their sources.

Also drops an unverified claim from the nemotron description. It said the
model drives the realtime transcription session; that endpoint actually calls
TranscribeStream, and the live RPC reaches LocalAI only through
realtime_semantic_vad.go. Neither path was exercised here, so the description
now states only the two calls that were.

MarbleNet gains the NeMo upstream under urls: for parity with silero.

No sha256, quantization, usecase or model choice changed.

* fix(audio-transform): bound sample_rate, keep same-named uploads apart

Four defects the whole-branch review found on the Go side, plus two comment
corrections.

sample_rate is a disk-exhaustion hazard. The branch added the `form:` tag that
makes the field bind for the first time, so the resample path went from dead to
live, and utils.AudioResample interpolates the int straight into ffmpeg's -ar
with no bound. Measured with ffmpeg 7: -ar 999999999 on a 0.01 s clip writes
20 MB and exits 0, which scales linearly to the reported 3.9 GB for one second,
into a GeneratedContentDir nothing sweeps, and convertStems repeats it once per
separation stem. Clamped to 8000..192000 in the handler, before the temp dir and
before the model is touched, and rejected with a 400 outside it.

The low end was reported as "a 0-byte file". It is not: -ar 1 writes a 78-byte
header with no audio behind it, whose declared data size still claims 70 bytes,
so go-audio parses it as a 35 SECOND file and a size check does not see it. The
guard therefore compares the declared data chunk against the bytes actually on
disk, and AudioResample now fails rather than returning a WAV carrying nothing.

Both parts of a transform request land in one temp dir, and the raw copy was
named only after the client's basename, so `-F audio=@mic/clip.wav
-F reference=@loopback/clip.wav` wrote "raw-clip.wav" twice. Since
AudioToWavPreservingShape hardlinks an already-PCM16 WAV rather than copying it,
the reference part's os.Create truncated the inode audio.wav pointed at: mic and
reference came out identical, which makes an echo canceller null everything and
return near-silence with a 200. The raw copy now carries the form field name.

audio-cpp had no BackendCapabilities entry, so VoiceCloningForModel returned nil
before it ever consulted the model's tts.voice_cloning override and every
`voice: "profile:<id>"` request was refused with a 400, on a backend that ships
audio-cpp-chatterbox whose family serves cloning and not plain TTS. Registered
with its RPCs, usecases and the reference-audio contract, and deliberately
without the 16 kHz mono fold, which its separation families cannot survive.

GetBackendCapability was exact-match only, so every pinned gallery variant read
as an unknown backend: vulkan-localvqe lost the 16 kHz mono fold that used to be
unconditional and started failing inside LocalVQE, and the usecase gate does not
stand in for it because BuildFilteredFirstAvailableDefaultModel returns early
once the client names a model. Lookup now falls back to the meta name by
stripping the gallery's hardware prefix and release-channel suffix, exact match
first so nothing can be shadowed. Same class as #10945.

Also corrected: the AudioTransformRequest comment claimed echo's binder falls
back to the field name, which it does not in either direction (bindData binds
ONLY tagged fields and `continue`s otherwise; `model` arrives from
setModelNameFromRequest's c.FormValue). And the stable_audio `src` heap
corruption caveat now lives on ElevenLabsSoundGenerationRequest, where the Go
developer who would add the field can see it, instead of only in C++.

* fix(audio-cpp): refuse a task pin the RPC cannot serve, and stop empty frames holding the lane

The model's `task:` option is copied into the request shape by all nine
handlers, which is correct, but resolve_route then replaced the RPC's candidate
list with the pin WHOLESALE and never asked whether the pin was something that
RPC routes to. One pin therefore bled across all nine surfaces, and because the
family still supported the pinned task the result was a wrong 200 rather than an
error. Reproduced live: nemotron with task:asr made Vad return 200 with zero
segments after a full ASR decode, so 14 seconds of speech was reported as
silence, and Diarize did the same; silero_vad with task:vad made
AudioTranscription return 200 with empty text and four segments whose spans were
VAD segments, which combined with response_format in {text,srt,vtt,lrc} building
the body solely from Segments[].Text yields a well formed SRT of four timed
EMPTY cues. It also contradicted the documented contract, that a family which
cannot serve a request is refused rather than rerouted.

A pin is now checked against the RPC's admissible task set before it is adopted,
and the refusal names both the pin and the RPC. The set is derived from
task_candidates with every shape flag set rather than restated, so a task added
to an RPC's candidates cannot become inadmissible by omission. Every legitimate
pin survives, and the test asserts all fifteen of them alongside the eight
crossings that must not.

The live watchdog was defeated by empty frames. idle.touch() ran on ANY message,
before the has_audio and pcm.empty() filters, so a peer writing unset-oneof or
zero-length frames faster than the window held the lane indefinitely while
feeding the decoder nothing. There is one lane per model and one model per
process, so that is a single client denying the whole backend, which is what the
watchdog exists to prevent, and the thrown text already said "no audio frame
arrived". The touch moved below the filters, which are now a named predicate so
the distinction is testable rather than a call order nobody can see.

Three comments corrected against measurement rather than reasoning:

- CMakeLists claimed zero google::protobuf:: definitions remain in the
  executable. nm -C --defined-only reports 2515, and that is expected: they are
  generated code, sentencepiece::ModelProto's own _InternalParse among them. The
  claim that holds, and the one the ABI fix is actually about, is that no
  vendored protobuf RUNTIME is linked and ParseContext::ParseMessage is
  UNDEFINED in the executable, resolving to libprotobuf.so.
- refuse_cloning_without_a_clip's "cannot misfire" paragraph had its reasoning
  backwards. Routing picks VoiceCloning as the FALLBACK when there is no clip,
  which is the case being caught; chatterbox, which ships in the gallery,
  advertises clon and no tts at all, so every voice-less request lands there.
- audio_units read "2.1 min at 96 kHz" for index 11289602, which is 1.96 min.
  2.1 min is 96 kHz's OWN first failure at 12288002. Both were remeasured and
  the note is now a per-rate table.

* build(audio-cpp): exclude the upstream checkout from the C++ gate, harden the darwin walk

run-unit-tests.sh pruned */llama.cpp/* but not */audio.cpp/*. It is safe today
only by luck: upstream's 44 tests all put "test" at the FRONT of the filename
(17 test-*.cpp, 27 test_*.cpp, zero *_test.cpp), so the glob misses every one of
them, and nothing enforces that. This gate runs on every PR for every backend
and compiles each match as a standalone translation unit with nothing but
nlohmann/json on the include path, so the day upstream adds or renames one test
the gate goes red repo-wide on an Apache-2.0 file nobody here wrote.

audio-cpp-darwin.sh now logs the raw otool -L output and the parsed LC_RPATH
list unconditionally, before the walk. Both awk filters in that script assume a
column layout nobody working on this can observe, since it runs only on the CI
Mac, and a green first Darwin run proves nothing about the assumption: an awk
that silently matched nothing yields an empty dependency list, which reads
exactly like "no non-system dependencies" and packages happily. Both filters
otherwise feed process substitutions, so their input never reached the log.

It also lists every symlink in the package and fails on one that cannot resolve
inside the image. A dangling link does not fail anything else here, because
every assertion tests with -e, which follows links; it fails at dlopen on a
user's Mac. Links are NOT banned outright, which the review suggested but which
would break the libggml.dylib -> libggml.0.dylib chain the `cp -a` above exists
to preserve. What is banned is a link that resolves on the build host and will
not resolve in the image: a broken one, or an absolute one pointing outside the
package.

* fix(config): key the voice-cloning model rule on the resolved backend

Making GetBackendCapability strip the gallery hardware prefix and release
channel fixed pinned variants of /audio/transform, but VoiceCloningForModel
kept keying its per-backend switch on the caller's spelling. A pinned name
therefore resolved the capability by stripping and then missed every case in
the switch, falling through to the permissive default: cuda12-vibevoice-cpp
advertised voice cloning for the realtime 0.5B model, metal-coqui for
tacotron2, cuda12-crispasr for a pure ASR model, cpu-qwen3-tts-cpp for
CustomVoice. Each of those is a model that cannot clone, so /v1/audio/speech
accepted a profile: voice it had to fail on inside the backend rather than
rejecting it with a 400, and the UI advertised the capability too.

resolveBackendCapability now returns the key the entry was found under, and
callers that branch on backend identity use that key instead of the name they
were handed. The exact-match-first order is unchanged, so a backend genuinely
registered under a variant-looking name still keys on its own name.

(src/models/chatterbox), and the entry's own description already said so, but
known_usecases listed only tts. /audio/transform selects its default model by
FLAG_AUDIO_TRANSFORM, so voice conversion was reachable only by naming the
model explicitly and was invisible to every usecase-driven surface. It is the
one audio.cpp task with a shipped gallery model and no way to find it.

Verified against the real model rather than inferred from the capability list:
AudioTransform with chatterbox-q8_0, speech as audio_path and a speaker clip
as reference_path, returns a 5.08 s 24 kHz mono WAV at -25.5 dB mean and zero
stems, which is the single-output shape voice conversion should have.

The description now says which endpoint reaches that half and warns that
installing this next to a source-separation model gives /audio/transform two
candidates, so the model should be named rather than defaulted.

* gallery(audio-cpp): add voice-design and singing-voice-conversion entries

Two of the three audio.cpp task kinds that had no gallery model now have one.
Both were driven end to end against the real weights through the backend
before being written, not inferred from the capability tables.

audio-cpp-irodori-voicedesign covers vdes. TTS carrying `instructions` routes
to the vdes task, so the voice is described in words rather than supplied as a
clip. Verified: "a calm elderly woman speaking slowly with a warm, gentle
tone" over an 8.76 s 48 kHz mono render at -16.8 dB mean, and a closed-loop
citrinet pass recovers the sentence with the accent drift expected from a
Japanese-first model read by an English recogniser.

audio-cpp-seedvc-singing covers svc, and pins task:svc because nothing else
can reach it. seed_vc advertises svc and ordinary voice conversion, no request
signal means "this input is singing", and auto-routing resolves the tie to
voice conversion every time. Verified with the pin: 5.04 s 44.1 kHz output
whose closed-loop citrinet transcription is exact.

s2s deliberately has no entry, and the reason is not effort. miocodec is the
only upstream family whose speech-to-speech route needs no text, and it
returned audio with correct duration and level but no recoverable speech in
four independent attempts: the stale build, v2 q8_0, v2 orig (the variant
upstream records as a clean Pass), both tasks, and matched 44.1 kHz inputs on
both sides. vevo2's route refuses with "Vevo2 text/prosody route requires
text_input or target_text", and session.cpp:897 fills target_text only from
request.text_input, which AudioTransform has no field to carry. The same
vevo2 weights convert voice correctly through the default route with an exact
ASR round trip, so the model and the plumbing are both healthy; it is the s2s
route specifically that this RPC cannot express.

* backend(audio-cpp): carry transform text through params, add the s2s entry

AudioTransform is audio-in / audio-out and its proto message has no text
field, but not every task it routes to is audio-only. vevo2's speech-to-speech
route is a text and prosody route: session.cpp:897 fills refs.target_text from
request.text_input and nowhere else, and the run refuses without one with
"Vevo2 text/prosody route requires text_input or target_text". The params map
is the only channel this RPC has that reaches the engine, so the text travels
through it and apply_transform_text_input unpacks it after the params have
been copied into task.options.

Before this, s2s was not awkward to reach through /audio/transform, it was
unreachable, and it was the last audio.cpp task kind with a real model and no
way to get to it.

target_text is canonical and text is its alias, the order vevo2's own option
table declares them in, so a request setting both gets the canonical one
rather than whichever the map happened to store first. An empty value falls
through to the next candidate instead of ending the search. language rides
along only when a text was found: on its own it conditions nothing, and
manufacturing a text_input for it would route a plain separation request
carrying a language hint through the text path. The keys are left in
task.options rather than erased, because vevo2's loader advertises target_text
as a request option and a family reading it there keeps working.

Nine tests, all confirmed failing on behaviour against a stub that returned
false before the implementation was written. Verified end to end afterwards:
vevo2-q8_0 with task:s2s and params[text] returns a 5.12 s 24 kHz output whose
closed-loop citrinet transcription is exact, and htdemucs separation with no
text param still returns its four stems, with and without params[stem].

audio-cpp-vevo2-speech-to-speech ships that route. Every audio.cpp task kind
with a loadable family now has a gallery entry; spk remains the only gap and
has no family upstream at all.

* docs(audio-cpp): document params[text] and the pinned transform tasks

The text channel and the two task pins are both invisible from the endpoint
contract alone: nothing in the AudioTransform form tells a reader that a
speech-to-speech model needs the line it is resynthesising, and nothing says
that asking for singing voice conversion without task:svc silently gets plain
voice conversion instead. Both are the kind of thing a user only discovers
from a refusal or, worse, from output that looks right and is not.

* fix(utils): annotate the two G304 sites this branch introduced

gosec flags os.Open on a variable path, and both new call sites in ffmpeg.go
are its alerts on this PR. Neither is reachable by an outside caller: isPCM16Wav
opens the exact path it is about to hand ffmpeg as input, which in the upload
path is a server-created temp file named from path.Base of the client name so
no traversal survives, and wavAudioBytes opens AudioResample's own dst, a name
this package derives from src and has just had ffmpeg write.

Annotated in the repo's existing style rather than restructured, with the
reason spelled out, because a bare suppression is worth nothing to the next
reader. The three other G304 sites in this file, in passthroughWAV and
isTargetWav, predate the branch and are left untouched.

* fix(audio-cpp): build arm64 with gcc-14 for the armv9.2 SME variants

The arm64 CPU image failed to build:

  cc1: error: invalid feature modifier 'sme' in
       '-march=armv9.2-a+dotprod+fp16+sve+i8mm+sve2+sme'

ggml's CPU_ALL_VARIANTS table includes armv9.2 variants compiled with +sme, and
Ubuntu Noble's default gcc-13 rejects that feature modifier. Every entry in the
table has to compile even though a host only ever dlopens the one its own CPU
supports, so a single unbuildable variant fails the whole image. gcc-14 accepts
it, which is exactly the fix llama-cpp already carries in
.docker/llama-cpp-compile.sh; this is the same problem reached by a different
Dockerfile.

Applied to every arm64 BUILD_TYPE rather than to the CPU one alone, and that
differs from llama-cpp on purpose. llama-cpp needs it only for its pure-CPU
image because its GPU builds run llama-cpp-fallback, which builds no variant
table. This backend's Makefile turns ENGINE_ENABLE_CPU_ALL_VARIANTS on for
every non-Darwin build, GPU included, so an arm64 GPU image would hit the
identical error. The matrix has no arm64 GPU entry today, which is precisely
why gating on an empty BUILD_TYPE would leave the trap armed for whoever adds
the first one.

d8a1e3c2e4 fix(realtime): echo response.metadata on response.created and response.done (#11198)
response.create accepts a metadata map and ResponseCreateParams has carried
the field all along, but triggerResponse never copied it onto the Response it
emits, so both terminals went out with metadata omitted.

That field is the only thing tying a terminal event back to the
response.create that asked for it. Our own doc comment on ResponseCreateEvent
says so — "the metadata field is a good way to disambiguate multiple
simultaneous Responses" — and it is what makes an out-of-band response
(conversation: "none") usable at all: a client running one alongside the
spoken conversation has no way to tell its own answer from the conversation's,
so it waits for a reply it already received and gave away.

Found from the client side: a headless text turn injected into a live session
was answered correctly in about a second, and the caller still blocked until
its own two-minute timeout because it could not recognise the answer.

Carry the map on liveResponse so all three terminals (in_progress, cancelled,
completed) report it, and leave it omitted when response.create sent none.

9bfd71387b feat(stores): add Valkey Search vector store backend (#11196)
* feat: add Valkey Search vector store backend

Add a new built-in Go gRPC store backend 'valkey-store' that implements the
four Stores RPCs (Set/Get/Delete/Find) against the Valkey Search module (FT.*)
using the pure-Go github.com/valkey-io/valkey-go client. It is selected via the
existing per-request 'backend' field on /stores, so there is no proto or HTTP
API change, and it mirrors the in-memory local-store while adding persistence
across restarts and opt-in HNSW.

Each vector is a Valkey HASH keyed by hex(little-endian float32); the index is
created lazily on first Set (FLAT+COSINE by default), cosine similarity is
derived as 1-distance, and namespaces get a collision-resistant token. Includes
unit tests (valkey-go mock) and env-gated integration tests against
valkey/valkey-bundle, plus build/matrix/gallery wiring and docs.

* Address review feedback: recover persisted index dimension, harden Find

- Load now recovers the persisted vector DIM from FT.INFO (not just index
  existence), so a post-restart Set/Find validates against the real DIM
  instead of silently re-learning a wrong one and dropping mismatched
  vectors from the index. This also restores Find's dimension check after
  a restart.
- StoresFind treats a dropped/missing index as an empty store (empty
  result, no error) and clears the stale indexCreated flag, matching
  local-store's empty-store behaviour.
- StoresSet reuses checkDims for its per-key length check so the four RPCs
  share one dimension-guard implementation.
- Add unit tests for FT.INFO dimension recovery, loadIndexState, and the
  dropped-index Find path.

* Address review feedback: TLS ServerName/CA, Find nil-check, config fail-fast

Addresses external review comments on the valkey-store backend:

- StoresFind now rejects a nil/empty query Key before dereferencing it,
  so a malformed gRPC request can no longer panic the backend.
- TLS: derive ServerName (SNI) from the VALKEY_ADDR host so certificate
  verification works for IP-addressed endpoints, and add VALKEY_TLS_CA_CERT
  (custom CA bundle) and VALKEY_TLS_SKIP_VERIFY (testing-only) knobs.
- Config integer parsing now fails fast on a malformed value (e.g.
  VALKEY_HNSW_M=1x6) instead of silently defaulting, matching the
  fail-fast behaviour of the index-algo/distance-metric validation.
- Add VALKEY_DB (SELECT n) support for logical-DB isolation.
- Cap the human-readable part of a namespace token at 64 chars so a very
  long model name cannot produce an unbounded key prefix / index name
  (the appended short hash keeps distinct namespaces collision-free).
- Document the KNN-query injection-safety invariant (fields are constants)
  and why StoresGet uses a single aggregate DoMulti deadline for reads.
- Unit tests for the Find nil/empty-key guard, fail-fast HNSW parsing,
  and VALKEY_DB parsing/validation; docs + .env updated for the new vars.

* Address review feedback: configure valkey-store via model config

richiejp asked that the valkey-store backend take its configuration from
a model config rather than process-wide VALKEY_* environment variables,
so multiple stores can each have their own Valkey config within one
LocalAI process. This removes every env access from the backend and
routes config through the model-config seam every other backend uses.

- config.go: loadConfig(opts *pb.ModelOptions) now parses the model
  config `options:` list (key:value strings, split on the first ':')
  instead of os.Getenv. Option keys mirror the old VALKEY_* names without
  the prefix (addr, index_algo, distance_metric, ...). Defaults, fail-fast
  validation and the mandatory client name are unchanged.
- store.go: Load threads opts into loadConfig; TLS comments/errors renamed
  off the VALKEY_* names.
- core/backend/stores.go: StoreBackend and NewVectorStore take a
  *config.ModelConfigLoader, resolve the per-store ModelConfig by store
  name, and pass its Options (and Backend when unset) to the backend via
  WithLoadGRPCLoadModelOpts. No config -> default backend + built-in
  defaults, preserving the zero-config experience.
- Endpoints/routes/application: thread the config loader to StoreBackend.
- Unit + integration tests: configure via options; the integration test
  passes addr through the model-config path (VALKEY_ADDR is now only the
  test harness locating the server).
- docs + .env: document the model-config options, drop the env var table.

The direct username / password options still work and take precedence when both are set (backward compatible). Includes 5 unit tests and updated stores.md documentation.

* fix: correct rebase artifacts in backend-matrix.yml and Makefile Fix two issues introduced by the conflict-resolution script during the rebase onto master: 1. .github/backend-matrix.yml: valkey-store entries were merged INTO the cloud-proxy entries (duplicate keys in same YAML map items) instead of being separate list items. This broke cloud-proxy Linux builds and the cloud-proxy darwin entry lost its build-type/lang. Fixed by making them standalone entries and restoring cloud-proxy exactly as on master. 2. Makefile: duplicated .NOTPARALLEL and docker-build-backends lines. Collapsed to single lines that are master's current content plus the valkey-store additions. Also adds the three optional pickups from #10801: - /valkey-store in .gitignore (the built binary) - valkey-store row in docs/content/reference/compatibility-table.md - valkey-store line in backend/README.md

9058a2bb46 feat: Add 3d generation UI/API and trellis2cpp backend (#10979)
* 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

  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

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

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

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

49ef40a187 feat(classifier/VAD): support voice control on low power devices (#10804)
* feat(llama-cpp): route Score through the slot loop

Score previously bypassed the slot loop with a direct llama_decode: a
conflict guard aborted the whole process if scoring raced generation, the
config validator had to reject score alongside chat/completion/embeddings,
and every candidate re-decoded the full shared prompt.

Add SERVER_TASK_TYPE_SCORE to the (patched) upstream server so score tasks
are scheduled like any other slot work: generation and scoring serialize
naturally, the shared prompt is decoded once per call, and the slot's
prompt cache carries the conversation prefix across calls. Context
checkpoints at the score boundary and at the cache-divergence point keep
SWA/hybrid/recurrent models (e.g. LFM2.5) from re-prefilling the whole
prompt per candidate: warm-turn scoring on a 6-option set drops from ~8s
to ~0.5s on a desktop CPU.

The conflict guard and the validation split are removed; declaring score
with generation usecases on one config is now supported and shares the
slot cache.

Classifier-mode responses: instead of autoregressive generation, each user
turn is prefill-scored against the option list (router.ScoreClassifier

canned reply and tool call are emitted through the existing response
machinery. Below-threshold turns take the configured fallback (none /
canned reply / generate); empty transcripts and unaddressed turns (wake
word not mentioned) skip scoring entirely. The scoring probe defaults to
the latest user message only — small scorers echo canned replies from
prior turns back as the top option otherwise.

Built for hardware that can afford prompt processing but not decode: with
slot-based Score the option list stays KV-cached across turns, so a turn
costs roughly one forward pass over the new words.

session_update_error events now carry the validation cause instead of a
generic message.

* fix(realtime): bound the VAD tick's scan window and buffer retention

The VAD tick loop re-scanned the entire input buffer every 300ms and only
trimmed it on zero-segment ticks or commits. Audio that keeps producing
segments without a committing pause (steady noise a mic pipeline lets
through, music, continuous speech) grew the buffer toward the 100MB cap
with each tick rescanning all of it — O(n^2), measured at ~3.3ms of silero
per buffered second: past ~90s retained, ticks run back to back and pin
~4 cores until the stream stops.

Silero's recurrent state only carries a few hundred ms of context, so
rescanning old audio buys nothing. Clip the slice handed to the VAD to the
largest silence the commit test can need to measure (server_vad silence
window or the semantic eagerness fallback) plus a warm-up margin, and
rebase the returned segment times so every downstream consumer keeps
whole-buffer coordinates. An open turn whose clipped window is all silence
now commits (the silence outran the window) instead of being discarded as
no-speech. Independently, retain at most 90s of raw buffer, rebasing the
live-feed and EOU cursors on trim — this also bounds the previously
unbounded VAD-error path. Turn boundaries are otherwise unchanged: no
forced commits, no new coordinator states.

pipeline.turn_detection.vad_window_sec can widen the scan window; values
below the automatic floor are ignored. The tick body is extracted into
vadTick so specs can drive turn detection synchronously (same shape as
classifySoundWindow); the babble reproduction that pinned 4 cores now
plateaus under 10% of one core.

state) and decodes every candidate's unique tail in one llama_decode.
Previously each candidate was its own task that restored the boundary
checkpoint and re-decoded its full tail sequentially, paying
per-candidate task and decode overhead.

The context reserves SERVER_SCORE_FORK_SEQS extra sequence ids (and
recurrent-state cells) beyond the parallel slots via the new
common_params::n_seq_score_forks. Forking requires the unified KV cache
(already this backend's default) since per-sequence streams would shrink
n_ctx_seq; an explicit kv_unified:false disables forking and Score calls
that need it fail cleanly. Candidates beyond the fork/output budget
decode in successive chunks.

Wire contract and scores are unchanged: per-token logprobs are stitched
from the shared region and the forked tails. Verified bitwise
deterministic call-to-call and independent of candidate order (no
cross-fork leakage via equal-length candidate swap); ranking matches the
per-candidate implementation on the drone battery (winner softmax
0.99996 vs 0.99997), and >16-candidate chunking, prefix-of-another and
empty candidates all pass.

Measured on a desktop CPU: warm /api/score calls 0.52s -> 0.23s; warm
realtime classifier turns 196-303ms. The 9-candidate drone turn decodes
~17 unique tail tokens in one batch instead of nine sequential ~220ms
checkpoint-restore tasks.

* feat(realtime): classifier argument slots via constrained completion

Hybrid classify-then-complete: a classifier option's canned tool call can
declare typed argument slots (number | enum | string, with defaults and
prompt hints) referenced as "{{name}}" in the arguments template. When
the option wins, the slots are filled by a short grammar-constrained
completion that continues the exact scoring prompt — rendered by the same
cached ScoreClassifier, so the llama.cpp prompt cache is already warm —
with the chosen route JSON re-opened at the first slot field. A GBNF
grammar pins the field skeleton and frees only the values; temperature 0,
a couple dozen tokens at most (~300ms on a desktop CPU for two slots).

Slot declarations and hints ride the option descriptions in the shared
system prompt, informing scoring and the fill alike at no per-turn token
cost. The localai.classifier.result event carries the final arguments and
a fill_latency_ms. On inference failure the slots' defaults apply; a slot
without a default fails the response (or falls through with
fallback.mode: generate). Slot filling requires completion alongside
score in the scoring model's known_usecases.

Verified end-to-end on the Pi drone demo: "fly forward three meters" in
distance mode classifies forward and infers {"distance": 3, "units":
"meters"} in ~310ms, and the drone flies exactly 3 units.

* feat(realtime): splice filled slot values into classifier replies

A classifier option's spoken reply can now reference its tool's argument

the reply as plain text before it is emitted, so what the assistant says
confirms what it actually inferred. Placeholders without a value stay
literal, and options without slots are untouched.

* feat(realtime): prewarm the classifier scoring prompt on registration

Swapping a session's classifier option list (a voice-switched command
mode, for instance) made the next turns pay a full re-prefill of the new
option-list prompt — measured 2.4s vs 0.3s warm on a desktop CPU, and
worse: on hybrid-memory models like LFM2.5, whose state cannot be
partially rewound (llama.cpp can only restore checkpoints), *every*
probe change re-prefilled from scratch whenever the last checkpoint
missed the probe boundary, so even same-list turns intermittently cost
full prefills.

Registering an option list (pipeline seed or session.update) now fires a
best-effort background prewarm: two throwaway scores with distinct
probes. The first prefills the new option-list prompt; the second,
diverging exactly where per-turn probe text starts, plants the backend's
rewind point (KV checkpoint) at the stable-prefix boundary that every
real turn reuses. The prewarm hides behind the canned mode-switch reply
— by the time it finishes speaking, the cache is warm. Idempotent per
option set, detached from the registering request's lifetime.

Measured on the drone demo (LFM2.5-1.2B, desktop CPU): first turn after
a mode switch 2374ms -> 340ms; intermittent same-list full prefills
(1.3-2.1s) all -> under 0.5s. For clients that swap lists frequently,
options: [parallel:2] on the scoring model additionally keeps one slot
per list via prefix-similarity routing (+26MB RSS, unified KV).

* perf(llama-cpp): checkpoint scoring at the caller-declared stable prefix

Hybrid-memory models (LFM2.5 shortconv, Qwen3.5 deltanet — where new
small models are headed) cannot rewind their state, so any prompt-cache
reuse that needs a rewind falls back to a full re-prefill. For classifier
scoring that meant every probe change re-processed the whole option-list
prompt: the server's checkpoints were placed reactively (at wherever the
previous task happened to diverge), so a checkpoint past the next
divergence was erased rather than restored — measured as intermittent
2-10s turns on prompts with a 95%+ common prefix.

The classifier now computes the probe-invariant prompt prefix once (the
byte-wise common prefix of two synthetic probe renders) and declares its
length with every Score request; the server maps it to a token boundary
and forces a KV checkpoint exactly there on each score prefill. That
checkpoint sits at or before every future divergence under the same
option list, so it always survives and always restores — repeat scoring
costs probe+candidates regardless of how the probe changes.

Also:
- prewarm reruns on every option-list registration instead of memoizing
  per list: with boundary checkpoints a redundant rewarm costs two
  probe-sized decodes, while skipping one after a slot eviction (three
  lists sharing fewer slots evict in LRU cascades) silently moves a full
  re-prefill onto the user's next turn
- new llama.cpp backend option rs_seq:N exposes bounded recurrent-state
  rollback outside speculative decoding; measured impractical for
  deltanet-scale states (65GB for 64 snapshots on Qwen3.5-4B) but cheap
  insurance for small-state models
- docs: the multi-list recipe (parallel:N + sps:0.5 — the default slot
  similarity threshold funnels distinct lists onto one slot)

Measured on the drone demo (LFM2.5-1.2B scorer, desktop CPU), steady
state: every turn 285-421ms including mode switches, vs 2.4s post-switch
and intermittent 1.3-2.9s re-prefills before.

* 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.

Refetching history on a shrinking live count missed a completion that

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): 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.

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.

* 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,

* 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.

05ff401de8 fix(test): stop the backend-trace specs racing the lossy trace channel (#11146)
RecordBackendTrace does a non-blocking send onto a 100-slot channel and
drops when it is full, so tracing never stalls inference. The payload
bounding specs pushed all 200 traces in one tight loop, which overruns
that channel on a loaded machine: entries are dropped for good and the
Eventually waiting for 200 can never be satisfied, no matter the timeout.
CI hit this on master at 0a8a7fbb, settling at 158/200.

Feed the traces in chunks of 50, draining after each, so the channel is
never overrun and the count stays exact. Reproduced with 60 busy loops on
a 20-core box at GOMAXPROCS=2: 0/12 runs passed before, 12/12 after.

* fix(tts): forward the OpenAI speed field to the backend (#11097)

/v1/audio/speech accepted the documented OpenAI `speed` field and then
dropped it: schema.TTSRequest had no Speed member, so the value never
reached proto.TTSRequest and the request returned 200 with an unchanged
playback rate.

Accept speed and normalise it into the existing per-request params map,
which core/backend forwards verbatim to the backend. An explicit
params["speed"] still wins, and a value outside the documented 0.25-4.0
range is now rejected with 400 instead of being silently ignored.

53006bb8e1 fix(realtime): accept legacy 'modalities' alias for output_modalities (fixes #11103) (#11104)
* fix(realtime): accept legacy 'modalities' alias for output_modalities

OpenAI's Realtime *beta* used the field name `modalities`; the GA field is
`output_modalities`. LocalAI only binds `output_modalities`, so a client
sending the still-common beta field `modalities: ["text"]` has it silently
dropped by encoding/json and the session falls back to audio: TTS runs and the
client receives large response.output_audio.* frames even though it asked for
text-only.

Accept `modalities` as an alias on both session.update (RealtimeSession) and
response.create (ResponseCreateParams). The GA `output_modalities` wins when
both are present, so GA clients are unaffected. Applied at the two existing
resolution points via a small modalitiesWithAlias helper.

Fixes #11103

output modality resolves to text (not audio), reproducing the exact

against a wrong JSON tag or a missed call site letting encoding/json drop
the alias silently.

Also document output_modalities (and the accepted legacy modalities
alias) for text-only sessions in the realtime feature docs.

5d57c08c6e feat(distributed): cache staged-artifact hashes and publish the model load lifecycle (#11121)
feat(distributed): cache staged-artifact hashes and publish load lifecycle

Every load request re-hashed every staged artifact on the controller
(probeExisting and the upload path both re-read the full file), which for
a large multi-file model on NAS-backed storage is minutes of pure
re-reading per request even when nothing changed - observed as ~9 minutes
of "Upload skipped (file already exists with matching hash)" before every
avatar generation. Cache the local hash in the same .sha256 sidecar the
worker-side transfer server already maintains, invalidated whenever the
sidecar is older than the file.

The whole staging+loading phase was also invisible: the NodeModel row was
only written after LoadModel succeeded, so /api/nodes and the UI showed
nothing while a cold load spent 10+ minutes staging - indistinguishable
from nothing happening. Publish the lifecycle instead: "staging" as soon
as the node is chosen, "loading" when the checkpoint load starts, and the
existing "loaded" on success, with the row removed on any failure so a
dead load does not leave a phantom replica. The early row also reserves
the replica slot against concurrent schedulers. The nodes view already
renders non-loaded states on model chips; style "staging" like "loading".

Audited every state-filtered registry/router query: eviction, routing,
reconciler and idle-model queries all filter state='loaded' explicitly,
so the new transitional rows are visible to observability surfaces but
inert to scheduling decisions (except slot occupancy, intentionally).

2d889e61a6 feat(backend): add magpie-tts-cpp text-to-speech backend (#11115)
* feat(backend): add magpie-tts-cpp text-to-speech backend

Add a Go + purego backend wrapping the magpie-tts.cpp ggml port of NVIDIA's
Magpie TTS Multilingual 357M (encoder + autoregressive decoder over NanoCodec
tokens), producing 22.05 kHz mono audio in 5 baked voices (Aria, Jason, John,
Leo, Sofia; case-insensitive names or indices 0-4) across 9+ languages from a
single self-contained GGUF. Mirrors qwen3-tts-cpp / moss-tts-cpp: dlopen the
static-ggml shared library, bind the flat magpie_tts_capi_* C-API via purego
(no local C shim needed, the upstream .so exports it directly), and serve the
gRPC TTS + TTSStream methods behind base.SingleThread (the C context is not
reentrant across synthesize calls).

The backend CMakeLists translates the Makefile's -DGGML_{CUDA,METAL,VULKAN,HIP}
flags into upstream's MAGPIE_GGML_* toggles (upstream FORCE-overwrites the ggml
cache entries from those), pinned to magpie-tts.cpp v0.1.1
(e3f3dd1ebe22b64e7405f93b519f2d1930712568), which statically links ggml into
libmagpie-tts.so (ldd shows only system libs).

Wires the full registration: backend-matrix.yml (CPU amd64/arm64, CUDA 12/13,
Intel SYCL f16/f32, Vulkan amd64/arm64, ROCm, NVIDIA L4T + L4T CUDA 13, and
Darwin metal), backend/index.yaml metas and image entries, the root Makefile
build targets, the changed-backends backend-filter path mapping, the bump_deps
auto-bump matrix, a test-extra per-backend smoke job, the /backends/known
pref-only importer entry, the backend capabilities map (TTS + TTSStream, no
voice cloning), and the README / compatibility-table docs rows.

Verified locally: unit + e2e Ginkgo suites pass against the real q8_0 GGUF
(22.05 kHz mono WAV, RMS > 0.01), a live gRPC LoadModel + TTS round-trip
returns valid non-silent audio, and the pre-commit gates (make lint,
make test-coverage-check) pass, run manually with LOCALAI_TEST_HTTP_PORT
overriding the locally-occupied 9090.

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.

f317da7c0f fix(galleryop): make admitted operations queryable and survive a failed op (#11044)
Two lifecycle defects observed on a 2-replica distributed cluster.

The install endpoints mint a job UUID, hand the operation to an unbuffered
channel, and answer HTTP 200 immediately. The gallery worker is a single
goroutine that processes operations serially, and the first status write
happens inside modelHandler/backendHandler — i.e. only once the worker
actually starts the work. An operation queued behind a running install
therefore had no status at all: GET /models/jobs/<uuid> answered
"could not find any status for ID" and GET /models/jobs did not list it,
so the endpoint reported success for work nothing could observe. On the
paths that sent directly rather than from a goroutine, the same unbuffered
channel blocked the HTTP handler for the whole duration of the in-flight
install, which is how a replica came to accept no /models/apply at all
while /readyz stayed green.

Admission now goes through EnqueueModelOp/EnqueueBackendOp, which publish a
"queued" status before handing the operation over, so a job ID is queryable
from the instant it is handed out. Delivery selects on the operation's
context, so cancelling a still-queued operation releases the delivery
goroutine instead of stranding it on a send that will never be received,
and an operation the worker never accepts becomes a terminal failure rather
than a silent leak.

The worker also had no panic containment. A panic in any handler propagated
out of the single consumer goroutine and killed the process, taking every
queued operation with it; it is now contained to the operation that caused
it. The two ignored galleryStore.Create errors are logged, and the model and
backend delete endpoints now run under the same ID they hand back — they
previously ran under an empty ID and returned a status URL for a job that
could never have a status.

Second, an operation orphaned by a controller replaced mid-download kept
reporting phase=downloading, processed=false, error=none while nothing was
downloading. The PostgreSQL side does recover on its own (FindDuplicate
ignores rows untouched for 30 minutes and CleanStale marks them failed), but
the reaper only ever corrected the database. The in-memory statuses map that
GET /models/jobs/<id> and /api/operations actually read was never corrected,
so every replica kept serving the frozen tick indefinitely. ReapStaleOperations
now reconciles the in-memory copy with the reap.

Note that operation ownership is still not tracked: gallery_operations has a
FrontendID column that nothing writes, so a live operation and one whose owner
died are distinguished only by a 30-minute staleness timeout. Narrowing that
window needs a lease/heartbeat mechanism and is out of scope here.

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

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

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

7a8db9b1f1 fix(ollama): set ContextSize via the embedded LLMConfig so the package builds (#11049)
The num_ctx clamping specs added in #11032 construct their fixture with
`config.ModelConfig{ContextSize: &existing}`, but ContextSize is not a
direct field of ModelConfig: it belongs to LLMConfig, which ModelConfig
embeds inline. Go allows reading a promoted field but not setting one in
a composite literal, so the test file has never compiled:

  helpers_internal_test.go:33:31: unknown field ContextSize in struct
    literal of type "github.com/mudler/LocalAI/core/config".ModelConfig

This broke `make lint` on master from bf19758e0 onward, and because the
typecheck failure takes down the whole package it also reds tests-linux
and tests-apple on every PR branched after that commit.

Use the same literal form the rest of the tree already uses for this
field (see core/backend/options_internal_test.go).

Worth noting the specs were not merely uncompiled but inert: #11032 is a
DoS fix (an unauthenticated client raising the context ceiling drives
KV-cache allocation), and its regression guard was never actually
running. Verified the restored specs are functional by stubbing out the
ceiling clamp, which fails the "does not let an oversized num_ctx raise
an existing context ceiling" spec as intended.

54f531f452 fix(mcp): bound MCP session connect so an unreachable server can't hang the widget (#10880) (#10884)
Establishing an MCP session held the session-cache mutex across
client.Connect with no per-connect timeout. An unreachable remote server
(bounded only by the 360s httpClient timeout) or a stdio server whose
initialize handshake never completes therefore blocked the caller and,
because the mutex was held, every other MCP request for that model too.
In the UI this shows up as the MCP "Servers" widget spinning forever.

It is most visible for cloud-proxy models: their chat path bails out
before the MCP tool block, so it never warms the session cache in the
background. The widget's /v1/mcp/servers/<model> call is then the first
and only code that connects synchronously, in the request foreground.

The session, once established, stays bound to the shared context (it is
cancelled later via the cached cancel func on eviction/shutdown), so we
can't pass a WithTimeout context to Connect: firing the timeout would tear
a healthy session down, and cancelling the shared context would also kill
sibling servers that already connected. Instead connectMCP runs Connect on
the shared context in a goroutine and stops waiting after the discovery
timeout, returning an error for that one server without disturbing the
others. A stalled goroutine is reaped when the model's sessions are
cancelled. Applied to both SessionsFromMCPConfig and
NamedSessionsFromMCPConfig.

d7020708f2 fix(completions): reject empty PromptStrings in streaming to avoid index-out-of-range panic (#11028)
* fix(completions): reject empty PromptStrings in streaming to avoid index-out-of-range panic

The streaming branch of CompletionEndpoint only guarded len(config.PromptStrings) > 1
before unconditionally reading config.PromptStrings[0]. A completion request whose
prompt field is an empty array, an array of non-strings, or omitted leaves
PromptStrings with length 0, so PromptStrings[0] panics with index out of range and
crashes the handler goroutine.

Guard for exactly one prompt string instead, returning a clean error for the 0-length
case as well as the pre-existing multi-prompt case.

* fix(completions): return 400 for malformed streaming prompt

Reject streaming completion requests whose prompt does not resolve to
exactly one string (omitted prompt, empty array, or a multi-element
array) with an HTTP 400 before writing any SSE headers, instead of
returning a plain error that Echo surfaces as a 500. Extract the guard
into validateStreamingPromptStrings and cover the three reported
payloads with a regression test.

bf19758e05 fix(ollama): cap num_ctx so it cannot wrap negative when cast to int32 (#11032)
* fix(ollama): cap num_ctx so it cannot wrap negative when cast to int32

applyOllamaOptions copied a client-supplied options.num_ctx straight into
cfg.ContextSize with only a > 0 check. That value is later cast to int32
before it reaches the backend (core/backend/options.go), so a num_ctx
above math.MaxInt32 silently wrapped into a negative context size that
was then sent to the LoadModel gRPC call. Both /api/chat and /api/generate
share applyOllamaOptions, so both endpoints were affected.

Cap num_ctx at math.MaxInt32 so the later cast stays positive, and add
internal regression coverage for the overflow, in-range, and unset cases.

num_ctx remains an intentional user override, so this does not re-impose
the hardware-aware auto context clamp; that policy choice is left to
maintainers.

Fixes #11022

* fix(ollama): clamp num_ctx to model context ceiling, not just int32

Per review on #11032: capping only at math.MaxInt32 still let an
unauthenticated request replace the hardware/model-derived context
limit with ~2.1B tokens, so a real backend could attempt a catastrophic
KV-cache allocation. Treat any existing positive cfg.ContextSize as the
server ceiling and clamp num_ctx down to it (smaller values still
honored), while retaining the int32-safe bound when no smaller ceiling
exists. Shared by /api/chat and /api/generate via applyOllamaOptions.

d7e04dcc32 fix(openresponses): make responses visible and cancellable across replicas (#11000)
In distributed mode the Open Responses store is process-local: a
sync.OnceValue over a map behind an RWMutex. With several frontend
replicas behind a round-robin load balancer, every request that lands on
a replica other than the creator misses.

Measured on a live 2-replica cluster (#10993): the same response id
returns 200 on the creating replica and 404 on its peer, and a cancel on
the peer returns 404 without ever invoking CancelFunc, so generation runs
to completion on the other replica while the caller is told the response
does not exist. previous_response_id chaining fails through the same
lookup.

Split the state by what can actually cross a process boundary:

- Replicated: response metadata (request, response resource, owner,
  expiry, stream/background flags) via syncstate.SyncedMap, the same
  component finetune, quantization and agent tasks already use. A local
  miss in Get/FindItem now falls back to it and returns a read-only
  remote view, so polling and chaining resolve on any replica.

- Delegated: cancellation. context.CancelFunc is a function pointer and
  exists only in the creating process, so a cancel that lands elsewhere
  is broadcast on responses.<id>.cancel and applied by whichever replica
  holds the function. The broadcast is fire-and-forget rather than
  request/reply: if the owner crashed or was scaled down nobody answers,
  and the handler must not block on a reply that will never come. The
  replicated status moves to cancelled either way, which is truthful,
  since a dead owner's generation died with its process.

- Refused: streaming resume. The resume buffer is a byte log plus a live
  notification channel and cannot be replicated without shipping every
  token over the bus. A resume that reaches the wrong replica now returns
  HTTP 409 naming the owning replica via the new ErrResponseNotLocal,
  instead of an empty event list that looks like a finished stream. It is
  deliberately distinct from ErrOffsetLost, which means the owner's
  buffer evicted the requested events.

Standalone deployments never call EnableDistributed and keep exactly the
previous process-local behaviour.

Fixes #10993

65bdbc4ee3 fix(http): make /readyz reflect startup readiness, plus gitignore and coverage-ratchet fixes (#10989)
* fix(http): make /readyz reflect startup readiness instead of always 200

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* feat(gallery): resolve meta model entries to hardware-appropriate variants at install

Meta gallery entries carry an ordered candidate list; at install time the
first candidate the host satisfies is resolved and its payload installed

variant backs it. The resolution is recorded in the installed gallery
config so a reinstall honors a prior pin and operators can see the backing
variant.

* 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.

llama.cpp one. An assistant reading the old schema would tell users the
wrong thing.

* 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.

9d82c37f98 fix(distributed): backend discovery hid worker-installed backends behind the controller's filesystem (#10967)
fix(distributed): backend discovery hid worker-installed backends

Backend discovery endpoints filter on installed-state, which on a
distributed controller derives from the controller's own filesystem. A
backend lives on the worker node that runs it, so every backend an admin
installed on a GPU worker read as "not installed" and vanished from the
listing. #10947 fixed the sibling capability filter on the same endpoints,
so a fine-tuning-capable GPU worker now made the backend listable while
the installed-state filter still dropped it: the dropdown stayed empty.

The controller cannot derive this locally, but it already aggregates the
per-node view that GET /backends renders, so discovery reuses the active
BackendManager rather than growing a second path. Three surfaces shared the
root cause and route through the same helper now:

  - GET /backends/available (Installed is now cluster-wide)
  - GET /api/fine-tuning/backends
  - GET /api/quantization/backends

The response stays a boolean rather than an installed-on-N-of-M count:
per-node install state is already served by GET /backends nodes[], and
per-node control by POST /api/nodes/:id/backends/install, so a summary is
all these dropdowns need.

A nil provider (single-node) leaves the local filesystem as the only source
and reproduces today's listing exactly, and a registry error degrades to
that same listing instead of blanking the catalog.

f735cb24c0 fix(worker): reap deleted backends and stop models that live on a worker (#10956)
* fix(worker): reap deleted backends and stop models that live on a worker

Three related backend-lifecycle defects, all reachable from the same
production incident on a Jetson/Thor worker: a deleted backend's gRPC
process survived ~40 minutes with its directory removed from disk, a later
model load was routed to that orphan and failed with a certifi path pointing
into the deleted directory, and the admin could not stop the model because
the frontend reported it as not loaded.

1. backend.delete orphaned the process it claimed to delete
------------------------------------------------------------
s.processes is keyed by `modelID#replicaIndex` (buildProcessKey), so the
backend name never appeared in a key and was recorded nowhere on the
process. backend.delete resolved its target via isRunning/stopBackend, whose
prefix path only matches a bare *modelID* - a delete keyed on a backend name
resolved to zero keys, the stop silently no-op'd, and the files were removed
out from under a live process.

The install fast path then handed that orphan back out: it returns any live
process for the (model, replica) slot without checking which backend started
it, so a reinstalled variant inherited the deleted backend's port.

- Record backendName on backendProcess, threaded installBackend ->
  startBackend.
- Add resolveProcessKeysForBackend, matching the recorded name and resolving
  alias <-> concrete via ListSystemBackends *before* DeleteBackendFromSystem
  erases the metadata that carries the alias. Alias resolution failure
  degrades to name-only matching so a delete never fails on it.
- backend.stop goes through resolveStopTargets, which accepts a backend
  name, a model name, or an exact modelID#replica key. Its payload field is
  named "backend" but is published with all three meanings: the admin UI
  sends a backend name, UnloadRemoteModel sends a model name, and the
  router's abandoned-load reap (#10948) sends an exact replica key.
  Narrowing it to backend names alone would strand the latter two.
  backend.delete stays strict - its identifier is unambiguously a backend.
- Gate the install fast path on processMatchesBackend so a slot held by a
  different backend is restarted rather than reused. Processes with no
  recorded name (pre-upgrade) are accepted, so rollout does not restart
  every running backend.
- stopBackendExact reports a real stop failure - the process still being
  alive afterwards, which is precisely what finishBackendStop already
  detects to keep the entry and its port reserved - and backend.delete no
  longer replies success when it knew about a process and could not kill it.
  "No process was running" stays a success but is logged, so the orphan case
  is visible rather than silent.

2. /backend/shutdown reported a running model as missing
---------------------------------------------------------
ModelLoader.deleteProcess short-circuits on a miss in this replica's
in-memory store. In distributed mode the authoritative record of "is this
model loaded" is the shared node registry: a frontend replica that never
served the model itself (load balancer picked a peer, or the replica
restarted) has no local entry. The remote unload path that pkg/model
documents ("when ShutdownModel is called for a model with no local process,
UnloadRemoteModel is called") sat behind that short-circuit, unreachable in
exactly the case it exists for. #10865 reworked this function but kept the
short-circuit at the top, so the gap survived that refactor.

- deleteProcess consults the remote unloader on a local-store miss, via a
  shared unloadRemote helper so this branch and the existing
  no-local-process branch both prefer #10865's RemoteModelContextUnloader,
  preserving force propagation across the distributed boundary.
- UnloadRemoteModelContext reports ErrRemoteModelNotLoaded when no node has
  the model; it previously returned nil, making a no-op stop
  indistinguishable from a real one. The converse case (nodes have it, none
  could be stopped) already errors since #10865 joined the per-node
  failures, so that half of the original fix was dropped as redundant.
- Only when the model is absent locally AND cluster-wide does the endpoint
  report not-found, now 404 naming both scopes rather than a bare 500.
- modelNotFoundErr becomes the exported ErrModelNotFound so the HTTP layer
  can map it without string matching; watchdog's identity comparison becomes
  errors.Is.

3. Coverage for the bounded Free() that #10865 shipped untested
----------------------------------------------------------------
The original branch also bounded the pre-stop Free(), but #10865 landed that
fix first (workerBackendFreeTimeout, applied in both stopBackendExact and
handleModelUnload). That production change is therefore DROPPED here as
superseded - master's version is strictly better, since it also releases the
supervisor mutex across the call and keeps the port reserved until
termination completes.

What #10865 did not ship is a test, and the bound is load-bearing: the
router-side reap in #10948 sends backend.stop for an abandoned load, and
against a wedged backend an unbounded Free would swallow that stop before it
reached the process. Nothing failed if the bound regressed.

The spec stands up a real gRPC backend server whose Free handler never
returns - what a Python backend looks like when its single worker thread
(PYTHON_GRPC_MAX_WORKERS=1 on 37 backends) is occupied by a stuck LoadModel.
A stub socket is not sufficient and was tried first: without a completed
HTTP/2 handshake, gRPC's own ~20s connect timeout ends the call, so that
version passed against the very bug it targets. With the connection READY,
only the caller's deadline can end it, so the spec hangs to its 60s limit if
the timeout is removed and passes with it.

Its fixture process is deliberately never started. go-processmanager v0.1.1
writes Process.pid from readPID() without synchronization, so a live process
races its own monitor goroutine under -race - reproducible with a bare
Run()+Stop() and unrelated to this spec. Since
scripts/model-lifecycle-conformance.sh runs this package with -race and is
fail-closed, starting one would turn that gate red on an upstream defect. An
unstarted process still proves the point: the stop is reached and the slot
released, which is exactly what an unbounded Free prevents.

Verified: make lint (new-from-merge-base origin/master) reports 0 issues;
scripts/model-lifecycle-conformance.sh passes all three stages including the
FizzBee liveness check (1458 states, IsLive: true).

* fix(distributed): keep remote unload idempotent, ask presence separately

2035a4d25 made UnloadRemoteModel return ErrRemoteModelNotLoaded when no node
holds the model, so ShutdownModel could answer 404 instead of a misleading
500. That narrowed a shared adapter contract to serve one caller and broke
the documented idempotent-unload guarantee, which CI caught on PR #10956:

  [FAIL] Node Backend Lifecycle (NATS-driven) > NATS backend.stop events
         should be no-op for models not on any node [Distributed]
         Expected success, but got: model not loaded on any node

The spec name states the contract outright. The matching unit assertion was
updated in that commit; this e2e one was missed because it lives under
tests/e2e/ with no build tags and does not run in package-scoped test runs.

Caller audit - who breaks when an idempotent unload becomes an error:

- pkg/model/watchdog.go:902 (LRU memory reclaimer) is the serious one. It
  untracks a model ONLY when shutdown returns nil or ErrModelNotFound. A new
  error type means the model is never untracked, so the reclaimer keeps
  re-selecting the same entry and never reclaims - a live wedge whenever a
  local store entry outlives the remote model.
- core/services/galleryop/managers_local.go:43 (DeleteModel) would warn on
  every deletion of an already-unloaded model.
- core/services/modeladmin/{state,config,remote_sync}.go stop instances
  best-effort against models that are frequently not loaded.
- deleteProcess itself: the no-local-process branch returns the unload result
  directly, so a stale local entry for a model no longer on any node turned a
  previously-successful cleanup into a failure.

Only ShutdownModel wants the distinction, and only on the local-store-miss
path. So the distinction moves to the caller instead of the contract:

- UnloadRemoteModel/UnloadRemoteModelContext return nil again when no node
  has the model, and ErrRemoteModelNotLoaded is removed.
- New optional RemoteModelPresenceChecker (HasRemoteModel) answers the
  question directly. deleteProcess consults it BEFORE unloading, because an
  idempotent unload cannot report afterwards whether anything was stopped.
  Absent locally AND cluster-wide is the only case that reports 404.
- A failed registry lookup is surfaced rather than reported as absence: an
  unreachable registry is not evidence a model is gone, and answering a
  confident 404 off a failed lookup is how an operator gets told a running
  model does not exist.
- Unloaders that predate the extension keep working - deleteProcess attempts
  the unload rather than refusing it - and compile-time assertions in the
  nodes package now pin all three optional interfaces, since both are
  consumed by runtime type assertion where drift degrades behavior silently
  instead of failing the build.

The contract is now pinned at both levels that disagreed, each spec pointing
at the other: "with no nodes returns nil" in unloader_test.go and "should be
no-op for models not on any node" in node_lifecycle_test.go.

Verified: full distributed e2e suite 233 passed / 0 failed (the suite that
failed 232/1 in CI); pkg/model and core/services/nodes green; make lint
new-from-merge-base reports 0 issues.

* fix(distributed): drop replica rows when a worker stops a backend

A worker returns a stopped backend's gRPC port to its allocator as soon as
the process is confirmed dead, and hands it to the next backend that starts.
The controller's NodeModel row for the old address survives, and both
SmartRouter.probeHealth and the HealthMonitor per-model probe verify
liveness, not identity, so once an unrelated backend binds the recycled port
the stale row passes every check and the request is served by the wrong
backend instead of failing.

backend.delete is newly able to trigger this: before #10956 a delete never
actually stopped a process, so it never recycled a port. backend.upgrade has
the identical gap and always did — upgradeBackend force-stops every process
using the binary and starts none back up, while
DistributedBackendManager.UpgradeBackend never removes rows. model.unload is
the one path that gets this right today: it calls RemoveAllNodeModelReplicas
straight after StopBackend.

Report the process keys the worker terminated on the delete and upgrade
replies, and drop the matching rows in RemoteUnloaderAdapter, which already
holds a ModelLocator with RemoveNodeModel. All three call sites funnel
through that adapter, so no new interface, DB migration, or proto change is
needed. A key is reported only once its process is confirmed gone, so the
list stays trustworthy on the partial-failure replies too.

Old workers never populate the new fields. ReportsStoppedProcesses tells
"stopped nothing" apart from "does not report", so an old worker's silence
falls back to the pre-existing probe-based staleness recovery instead of
being mistaken for a completed cleanup.

Quarantine released ports for a short window as an interlock covering the
NATS round-trip between the worker freeing the port and the controller
dropping the row. It is deliberately not derived from HealthCheckInterval:
that cadence is operator-tunable and the per-model reaper can be disabled
outright, so coupling a worker-local constant to it would be silently wrong
on some clusters. Eager row removal is the fix; the delay only closes the
handoff gap.

Identity verification in probeHealth was considered and rejected: Health and
Status carry no backend identity, so it needs a proto change plus an
implementation in 36 Python and 4 C++ Health servicers, it is fail-open for
any backend not yet rebuilt, and the probeCache short-circuit means it would
not even execute during the 30s window where the misroute happens.

* chore(deps): bump go-processmanager, assert real backend termination

go-processmanager wrote Process.PID from readPID() with no synchronization
while its own monitor goroutine cleared the same field on exit, so a bare
Run()+Stop() tripped the race detector without any concurrent access from
the caller. LocalAI hit this on every backend stop.

Upstream fixed it in a94e2b7 by guarding PID with a mutex and adding
CurrentPID() as a race-safe accessor. The exported field was kept to avoid
a breaking change but is now deprecated: a direct read still races the
monitor. No tag carries the fix yet, so pin the pseudo-version.

GetGRPCPID reads through CurrentPID() instead of the field. The accessor
returns the same string under an RLock, so the empty-PID and strconv error
paths are unchanged; it is the only direct field read in the tree.

With the race gone, the Free-timeout spec no longer has to leave its
fixture process unstarted. It now runs a real child and asserts the child
genuinely exits, which is exactly what the earlier workaround gave up: the
spec could show the stop was reached and the slot released, but not that
SIGTERM ever landed. Termination is observed through Done(), which closes
only once the library has waited on the child. The pidfile-based liveness
helpers cannot serve here, because Stop() deletes the pidfile while
releasing the handle and so reports "not alive" even if no signal was sent.

b19afb192a fix(distributed): backend discovery hid GPU-only backends behind the controller's capability (#10947)
* fix(backends): list backends runnable on worker nodes in distributed mode

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

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

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

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

* fix(backends): union worker capabilities in backend discovery

Implementation for the specs added in the previous commit, plus the two
remaining discovery endpoints.

Capability-filtered backend discovery evaluated compatibility against the
system state of the host serving the request. In a distributed deployment
that host is the controller, which typically has no GPU, while the GPUs
live on worker nodes. Any meta backend whose capabilities map lacks a

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

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

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

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

0389495388 fix(webui): use relative asset base so fonts and lazy chunks honor X-Forwarded-Prefix (#10889) (#10904)
The Vite build emitted path-absolute asset URLs (base: '/'). index.html
entry scripts and the favicon were rewritten to include the reverse-proxy
prefix in serveIndex, but two reference kinds are not in index.html and so
bypassed that rewrite:

  - CSS `url()` font references (e.g. Font Awesome .woff2), which the browser
    resolves relative to the stylesheet and which `<base href>` never affects
  - lazily-imported route chunks, whose preload base came from the absolute
    Vite base

Under a subpath mount (X-Forwarded-Prefix: /llm/) both were fetched from the
origin root, 404ing — missing-glyph "tofu" icons and broken lazy-loaded pages.

Switch Vite to a relative base ('./') so every generated URL resolves against
the file that references it: CSS fonts and route chunks now load from
`/llm/assets/...`, and index.html's now-relative entry refs resolve via the
`<base href>` serveIndex already injects on every response. Root deployments
are unaffected. The existing path-absolute rewrite in app.go still covers the
public `/favicon.svg`.

4be6e22b5f feat(webui): surface user, client IP and user agent in API traces (#10886, #10887) (#10907)
The Operate → Traces "API Traces" panel already recorded who made each
request (user_id/user_name) but never showed it, and did not capture the
caller's network identity at all. Operators asked to see the requesting
user (#10886) and the client IP + user agent (#10887) so a trace can be
attributed to who/what issued it.

Backend: add ClientIP and UserAgent to APIExchange and populate them from
echo's c.RealIP() (honours X-Forwarded-For / X-Real-IP behind a trusted
proxy) and the request's User-Agent header. Both are omitempty and the
/api/traces swagger response is map[string]any, so this is additive.

UI: add a sortable "User" column to the API traces table and a metadata
block (User / Client IP / User Agent) at the top of the expanded row
detail. Fields render only when present, so older buffered traces and
unauthenticated/local requests degrade cleanly.

Adds an e2e spec covering the new column value and the expanded metadata.

bf484c5181 feat(webui): show date alongside time in the Traces view (#10888) (#10905)
The Operate -> Traces table rendered the request time with the time of day
only, so entries that span more than one day were ambiguous. Add a
formatDateTime helper (localized date + existing time-with-millis) and use it
for the Traces "Time" column, keeping the cell on a single line. The shared
formatTimestamp used by the log views is unchanged.

6ccb1130d8 fix(agent-ui): reset streamed text at generation boundaries in agent chat (#10664)
One agent turn runs several internal LLM generations (tool selection,
reasoning, final answer) that all emit stream_event deltas over the same
per-agent SSE channel. The chat page accumulated every 'content' delta
into a single live bubble and ignored the 'done' boundary events, so the
internal generations' text (e.g. the English tool-selection rationale)
merged with — and visually corrupted — the streamed final answer.

Reset the accumulated content/reasoning on 'done': each generation gets
a clean live bubble, and the authoritative full answer still arrives via
the final json_message event as before.

dc2cc4da43 fix(audio-transform): serialize WebSocket writes to avoid concurrent-write panic (#10857)
* fix(audio-transform): serialize WebSocket writes to avoid concurrent-write panic

AudioTransformStreamEndpoint writes to the same Gorilla WebSocket connection
from two goroutines: the backend-forwarding goroutine emits binary PCM frames
(and can call sendWSError on a backend recv error), while the read loop calls
sendWSError for malformed mid-stream JSON or a backend send failure. Gorilla
WebSocket permits only one concurrent writer, so these writers race and can
panic with "concurrent write to websocket connection", resetting the client
session; a -race build reports the data race directly.

Wrap the connection in a lockedConn that serializes WriteMessage behind a
mutex, mirroring the existing lockedConn used by the openresponses WebSocket
endpoint. Reads stay on the single read loop, so only writes need the lock.

process-global budget (that stays standalone-only); the server resolves
and enforces the budget uniformly (Task 6).

Also closes a Task 6 gap: on re-registration, a struct Updates zero-skips
an empty budget, so a worker that dropped LOCALAI_VRAM_BUDGET left the
stale cap in place. For non-admin-override nodes the budget columns are
now force-written (map Updates) even when empty, so removing the env var
clears the cap; admin overrides are preserved unchanged.

budget a second time. For an absolute budget this is idempotent, but for
a percentage budget b.Apply resolves the ceiling as a fraction of its
input total, so a second pass yields P*(P*T) instead of P*T and distorts
UsagePercent (read by the memory reclaimer in pkg/model/watchdog.go).

Remove the redundant second application so the budget is applied exactly
once, against the raw physical totals, upstream in GetGPUAggregateInfo.

3601174ce0 fix(distributed): make per-node backend upgrade actually upgrade (#10838)
* test(core/http): make the suite's HTTP port overridable

app_test.go and openresponses_test.go hardcoded 127.0.0.1:9090. When
another service already listens on 9090 the suite does not fail fast:
the server goroutine logs the bind error and the specs then poll
whatever is squatting the port until Eventually times out. On machines
where 9090 is permanently taken this makes the pre-commit coverage gate
impossible to pass.

Introduce testHTTPAddr, defaulting to 127.0.0.1:9090 (what CI has
always used) and overridable via LOCALAI_TEST_HTTP_PORT for local runs.

* fix(distributed): make per-node backend upgrade actually upgrade

The node detail page's Upgrade button reused the node-scoped install
path (POST /api/nodes/:id/backends/install). That fires NATS
backend.install with force=false, and the worker's install handler is
deliberately "ensure installed": when the backend binary already exists
on disk it short-circuits without touching the gallery. Since only an
installed backend can be upgraded, the whole chain was a guaranteed
successful no-op - the UI then toasted "backend upgraded" without even
waiting for the async job.

Route upgrades through the real force-reinstall path instead:

- BackendManager.UpgradeBackend now receives the ManagementOp (like
  InstallBackend already did) so implementations can honor
  op.TargetNodeID.
- DistributedBackendManager.UpgradeBackend scopes the backend.upgrade
  fan-out to op.TargetNodeID when set, and errors when the target node
  does not report the backend as installed.
- New POST /api/nodes/:id/backends/upgrade endpoint enqueues an
  Upgrade=true node-scoped op (async 202 + jobID, mirroring install).
- NodeDetail UI calls the new endpoint and reports the dispatch
  ("Upgrading ... on this node...") instead of claiming success; the
  Operations panel tracks the actual job.

Verified against a live local cluster (NATS + Postgres + two workers):
the target worker stops the running process, force-reinstalls from the
gallery and re-downloads the OCI image; the second worker receives no
backend.upgrade event; upgrading a backend missing from the target node
fails the job with a clear error.

a5aa56db81 fix: preserve uploaded file content when regenerating a non-last answer (#10819)
handleRegenerate rebuilt the outbound message from the display-only
message.files metadata ({name, type: 'file'|'image'|..., content}),
which doesn't carry the base64/textContent payload sendMessage's
file-building loop expects. As a result, regenerating any answer whose
own question had an attachment silently dropped that attachment from
the resent message. This wasn't fork-specific, but forking a chat and
then regenerating an earlier (now non-last) answer is the natural way
to hit it.

Fix by reusing the original message's already-assembled `content`
verbatim (it already has the file text / image_url / audio_url /
video_url parts embedded from the first send) instead of trying to
reconstruct it from lossy display metadata.

Fixes #10806

a0ed395cf9 fix(auth): accept EC/PS/EdDSA-signed OIDC ID tokens, not just RS256 (#10736)
The OIDC verifier was built with a bare oidc.Config{ClientID: ...}, so
go-oidc applied its default of accepting RS256-signed ID tokens only. An
identity provider configured with an EC signing key (e.g. Authentik) issues
ES256-signed tokens, and the callback failed verification with:

  failed to verify ID token: oidc: malformed jwt: unexpected signature
  algorithm "HS256"; expected ["RS256"]

surfacing to the user as HTTP 500 "failed to fetch user info" (#10677; the
underlying cause became visible after the logging fix in #10679).

Set SupportedSigningAlgs to the standard asymmetric algorithms
(RS256/384/512, ES256/384/512, PS256/384/512, EdDSA). All are verified
against the provider's published JWKS. HS256 is intentionally excluded: it
is symmetric and would validate against the client secret, a different and
security-sensitive trust model.

Tested with a functional spec that signs an ES256 ID token and confirms it
verifies with the configured algorithms and is rejected under go-oidc's
RS256-only default (using oidc.StaticKeySet, no network).

cd65a1f645 fix(transcription): honor model-config language/translate + OpenAI language form field (#10731)
fix(transcription): honor model-config language/translate, add language form field

The /v1/audio/transcriptions endpoint read only input.Language /
input.Translate from the parsed request, and the request middleware never
populates those from a multipart upload -- nor did it read a `language`
form field. As a result the model config's parameters.language /
parameters.translate (a valid PredictionOptions field under `parameters:`)
were silently ignored, and multilingual models like canary defaulted to
translating into English even when the YAML set language: ru,
translate: false (#10655).

Resolve both with clear precedence: the request form field wins, then any
language on the parsed request, then the model config default. This also
makes the endpoint honor OpenAI's `language` form parameter, which was
not read before.

Applies to both the streaming and non-streaming paths (the resolved
values are built into the shared TranscriptionRequest). Note this ensures
the language/translate flags reach the backend; whether a given engine
acts on them is up to the backend.

Closes #10655
