a740a25934 fix(ci): skip the master image rebuild for commits no image can see (#11223)
On 2026-07-30, 12 of the 23 queued runs of this workflow were commits like "add
1 new model to gallery" or a docs fix, each rebuilding all 18 container images.
That was roughly 216 queued jobs producing byte-identical output, in a queue
holding 1071 jobs with an oldest entry two days old.

Verified against the shipped Dockerfile before assuming it: the final stage
copies only entrypoint.sh, healthcheck.sh and the local-ai binary, there is no
go:embed of gallery/ or docs/, and the gallery is fetched at runtime from
github:mudler/LocalAI/gallery/index.yaml@master. A gallery-only commit produces
an identical image, and the gallery change reaches users through GitHub whether
or not an image is rebuilt, so nothing is delayed by skipping.

Add a `changes` job that decides once whether the push can affect an image; the
other 11 jobs take `needs: changes` and an `if:` on its output.

A job gate rather than paths-ignore on the trigger, for two reasons that both
fail silently if got wrong:

  - paths-ignore on `push` also applies to tag pushes, and a tag created on an
    existing commit carries an empty commits list. That would skip the release
    image build with no failure anywhere. The gate short-circuits to build for
    refs/tags/*, and for a base commit that is missing, zero or unresolvable --
    the same run-everything posture the backend matrix filter takes for a
    truncated diff.
  - the merge jobs use `if: ${{ !cancelled() && ... }}`, and !cancelled() is
    true when a dependency is skipped, so they need the gate named explicitly
    or they would try to merge manifest lists for images never built.

Checked the decision logic against real commits from the queue: the two
gallery/docs commits resolve to build=false, the two code commits to build=true,
and all three fallback paths (tag, zero base, unresolvable base) to build=true.

a1620579c7 fix(ci): skip the core image and release build on backend-only diffs (#11224)
Version-pin bumps dominate PR volume: 48 update/* PRs in the week to
2026-07-30, from 16 pins, each a two-line diff. bump_deps.yaml runs a 28-entry
matrix daily and opens one PR per moved pin; CRISPASR and the gallery checksum
produced one every day, ik-llama-cpp six in seven days. Almost all of them edit
nothing but a single backend/*/<name>/Makefile.

Neither image-pr.yml nor build-test.yaml can observe such a change. `make build`
is `go build ./cmd/local-ai`, GoReleaser builds that plus ./cmd/launcher, and
the core image's final stage ships only entrypoint.sh, healthcheck.sh and the
binary. The per-backend trees are copied into the builder but nothing in them
reaches the output. That is 7 + 3 jobs per bump PR that cannot fail for a reason
the diff caused, roughly 410 jobs a week.

Add backend/{cpp,go,python}/** to the paths-ignore of those two workflows. The
inputs that do reach the binary are deliberately outside those prefixes and so
still trigger a full run: backend/backend.proto (protogen-go), go.mod/go.sum
(the go mod tidy before-hook), and backend/Dockerfile.* .

Not applied to the workflows that genuinely read that tree:

  test.yml      TEST_PATHS names ./backend/go/{cloud-proxy,local-store,
                valkey-store}/...
  lint.yml      .golangci.yml carries backend/-scoped rules
  tests-e2e.yml the e2e suite drives real backends over gRPC
  backend_pr.yml its whole job is rebuilding the changed backend

Simulated against the change shapes that occur in this repo. Pin bumps and
python requirement bumps skip; backend.proto, go.mod, a core Go edit, a
backend/Dockerfile edit and any mixed diff all still run, since paths-ignore
skips only when every changed file matches.

c4617265b9 fix(ci): trim two pieces of per-PR work that buy nothing (#11219)
Measured over the week to 2026-07-30, 97% of CI wall-clock is queueing and 3%
is execution: a median 5-hour queue against a 4-20 minute median job. With the
queue saturated, throughput is concurrency divided by service time, so cutting
execution time raises the drain rate directly. Two steps stood out as paying
nothing for what they cost.

test.yml: drop the free-disk-space step (~3.1min per run, ~22 h/week). That
action exists to make room for docker buildx layers and this job runs no buildx
step. It was also sized for a `make test` that downloaded multi-GB GGUF/whisper
fixtures and built llama-cpp/whisper/stablediffusion-ggml; the test-suite reorg
moved all of that into tests/e2e-backends and tests/e2e-aio, as the Makefile
test target already records. Its tool-cache:true wipe was additionally deleting
/opt/hostedtoolcache, forcing setup-go and setup-node to re-download toolchains
that ship preinstalled on the runner.

build-test.yaml: build only the host target on pull_request. The three-platform
cross-compile (linux/amd64, linux/arm64, darwin/arm64) is the bulk of that job's
~6.6min median, ~47 h/week, and nothing consumes a PR's binaries. goreleaser's
--single-target still runs every before-hook (protogen-go, react-ui, go mod
tidy), so the "is the release build broken" signal is unchanged. master pushes
and tags keep building all three.

Also record why the Linux Go workflows pass cache: false to actions/setup-go,
since it reads as an oversight and is not. Set up Go has a median of 11 seconds
on those runners, so there is nothing to win, and the repo already sits at
GitHub's 10 GB Actions cache ceiling with 31 entries, where each setup-go entry
is 222-375 MB on Linux and up to 1.4 GB on macOS. Re-enabling it would evict
something that is earning its space.

47097041ff fix(vllm): apply Options[] engine flags before engine init (#11147)
fix(vllm): apply Options[] engine flags before engine init (#11130)

CLI-style flags in a model's `options:` array (`--quantization:gptq_marlin`,
`--enable-prefix-caching`, `--kv-cache-dtype:fp8_e5m2`) were discarded: the
backend only ever read `tool_parser`/`reasoning_parser` out of Options[], and
did so *after* `AsyncLLMEngine.from_engine_args()`, where nothing it set could
still reach the engine.

Map `--` prefixed options onto the AsyncEngineArgs dataclass before the engine
is constructed. Names are normalized the way vLLM's CLI spells them
(`--enable-prefix-caching` -> `enable_prefix_caching`), values are coerced to
the target field's type (bare flag -> True for booleans), and unknown or
uncoercible flags warn and are skipped instead of failing the load, since
Options[] is a bag shared with backend-level settings. Field types come from
the annotation's base so `Literal["auto", "float16"]` (vLLM's dtype) is not
mistaken for a float.

Precedence is typed proto fields -> `options:` -> `engine_args:`. The
production engine_args defaults seeded in hooks_vllm.go therefore skip any key
the user already set as an option, otherwise the later engine_args pass would
silently override it. Parser lookups now accept both spellings, so
`--reasoning-parser:qwen3` selects LocalAI's parser as well.

The helper's tests are stdlib-only and run in the lint workflow's
dependency-light job via `make test-python-helpers`.

* 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.

                                           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

                                           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.

* gallery(audio-cpp): declare audio_transform on the chatterbox entry

Chatterbox advertises VoiceCloning AND VoiceConversion
(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

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.

d225e15f0f fix(ci): skip the image and Go PR workflows on content they cannot see (#11218)
backend_pr.yml and test-extra.yml already filter themselves, so a gallery-only
or docs-only PR costs them about one job each. The image and Go workflows had no
filter of any kind, so a one-line gallery/index.yaml edit queued 20 jobs: 7
container image builds, 3 GoReleaser/darwin launcher builds, 3 unit test jobs, 2
golangci-lint, 1 e2e, 1 yamllint, plus the 3 that correctly stop after their
detect step. A docs-only PR queued the same.

This matters more than the job count suggests. Measured over the week to
2026-07-30, 97% of CI wall-clock is queueing and 3% is execution: a median
5-hour queue against a 4-20 minute median job. Cutting job count is the only
lever that shortens feedback time. The volume is there to cut, too: 13
gallery-only PRs merged that week with 10 open at once, and 78 of the 137 PRs
opened were bot-generated.

Add paths-ignore for gallery/**, docs/**, examples/** and **/*.md to the
pull_request trigger of image-pr.yml, build-test.yaml and tests-e2e.yml, and
add gallery/** to lint.yml, which already excluded the rest. That drops 13 of
the 20 jobs. None of the four can observe such a diff: gallery metadata is
parsed at runtime and never copied into an image, docs and markdown never enter
one at all, GoReleaser and the launcher take no such input, the e2e suite drives
backends over gRPC directly, and golangci-lint runs new-from-merge-base so a
diff with no touched Go lines is a no-op. The build-test exclusion also frees
macOS capacity, which is the scarcest runner class.

The two checks that do validate the gallery are deliberately left alone.
test.yml still runs core/gallery/variants_lint_test.go, which reads the real
gallery/index.yaml and asserts the index invariants, and yaml-check.yml still
lints the syntax.

paths-ignore skips a run only when every changed file matches, so a PR touching
the gallery and Go code still runs everything. master carries no branch
protection and no rulesets, so a skipped workflow reports no status and nothing
waits on it; .agents/ci-caching.md records that constraint for whenever required
status checks are introduced.

image.yml on master push is left unfiltered on purpose: skipping it would stop
the master and latest tags being republished for a gallery commit, which is a
publishing decision rather than a cost one.

- 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.

  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

  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

856b0ea951 fix(ci): build the CUDA 13 image on Ubuntu 24.04 (#11143)
* fix(ci): build the CUDA 13 image on Ubuntu 24.04

The amd64 `-gpu-nvidia-cuda-13` image is the only runtime image still
built FROM ubuntu:22.04. The Ubuntu 24.04 migration (#7769) bumped its
`ubuntu-version` to 2404 but left `base-image` on jammy, so the image
ships glibc 2.35 while adding the noble CUDA apt repository, and every
backend it unpacks is built on noble.

Backends therefore cannot dlopen the libraries they bundle. The vLLM
backend dies at import time with:

  OSError: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.38' not
  found (required by /backends/cuda13-vllm/lib/libnuma.so.1)

and torchcodec finds no usable libavutil because jammy ships ffmpeg 4.x
(libavutil.so.56) while torchcodec looks for .so.57 through .so.60.

Add a spec over the build matrices that fails when a base image and the
`ubuntu-version`/`ubuntu-codename` it is paired with disagree, or when
the runtime images are split across Ubuntu releases. Entries whose base
image does not name a release (JetPack) are left alone.

The `base-grpc-cuda-13-amd64` builder base stays on jammy: it only
compiles backends, and a lower glibc floor in a builder is safe.

4baa36ddd8 feat(backend): vllm-cpp - text-generation backend for vllm.cpp with llama.cpp-parity tool calling (#11100)
* feat(backend): add vllm-cpp text-generation backend (vllm.cpp)

Wrap https://github.com/mudler/vllm.cpp - the LocalAI-team from-scratch C++20
port of vLLM (paged KV cache, continuous batching, prefix caching, safetensors
+ GGUF loading, no Python at inference) - as a Go gRPC backend over its stable
C ABI (ABI v2) via purego.

Backend (backend/go/vllm-cpp):
- Load -> vllm_engine_load: accepts a .gguf file or a config.json model dir
  (anything else is refused, satisfying the greedy-probe rule); context_size
  maps to max_model_len, options block_size/num_blocks/max_num_seqs size the
  KV cache and scheduler admission.
- Predict -> vllm_complete (blocking); PredictStream -> vllm_complete_stream
  with the per-delta C callback bridged into the gRPC stream. The backend
  embeds base.Base (not SingleThread): concurrent requests batch continuously
  in the engine's shared AsyncLLM scheduler.
- PredictOptions.Grammar -> the ABI's structured_grammar (GBNF), giving
  grammar-constrained tool calling at parity with llama-cpp; the ABI also
  exposes JSON-schema/regex/choice constraints.
- Hand-mirrored POD structs with layout locked by unit tests
  (unsafe.Offsetof vs the C offsets) and a runtime vllm_abi_version gate.
- One portable library per platform (vllm.cpp uses per-file SIMD tiers with
  runtime dispatch), so no avx/avx2/avx512 variant builds.

Wiring:
- backend-matrix: CPU amd64+arm64 (per-arch + manifest merge), CUDA 12/13
  amd64 (120a;121a Blackwell fat binary), L4T arm64 (121a, GB10/DGX Spark -
  the runtime-proven GPU target), Vulkan amd64, and Darwin arm64 Metal.
- backend/index.yaml meta + 12 image entries (latest/development x cpu,
  cuda12, cuda13, l4t, vulkan, metal); bump_deps registration for the
  VLLM_CPP_VERSION pin; root Makefile registration; test-extra runs the unit
  specs (pure Go, no engine build).
- Importers: preference-only swaps - llama-cpp (GGUF) and vllm (safetensors)
  advertise vllm-cpp via AdditionalBackends and emit backend: vllm-cpp
  without tokenizer templating (the C ABI takes the FINAL prompt; templating
  and tool parsing stay LocalAI-side). No auto-detect importer.
- Docs: backends list, top-level README maintained-engines table,
  compatibility table.

Verified: 20/20 Ginkgo specs against the real pinned engine and
Qwen3.5-2B-UD-Q8_K_XL.gguf on CPU - blocking + streaming parity, greedy
determinism, stop words, GBNF-constrained generation, and 4 concurrent
streams; plus a dlopen/ABI-gate smoke of the built gRPC server binary.
Upstream ABI v2 + production structured-output wiring landed as
mudler/vllm.cpp@86013f3.

* feat(vllm-cpp): ride the autoparser code path - engine-side chat templating and tool engagement (ABI v3)

The backend now implements AIModelRich (PredictRich / PredictStreamRich) over
vllm.cpp's ABI v3 chat entry points, so chat and tool calling ride the SAME
code path as the llama.cpp autoparser: the ENGINE renders the model's chat
template, decides when a tool call engages, and parses it - LocalAI receives
pre-parsed ChatDelta / ToolCallDelta protos exactly as it does from llama-cpp.

- With use_tokenizer_template + structured Messages, PredictOptions lowers to
  ONE OpenAI chat request JSON (messages, tools, tool_choice, sampling,
  stream_options.include_usage) for vllm_chat / vllm_chat_stream. tool_choice
  auto lowers engine-side to a LAZY structural-tag decode constraint - free
  text until the model emits the tool trigger, then the call is
  grammar-constrained; required/named force a call. Tool output is parsed by
  the engine's streaming Hermes-style parser; each chat.completion.chunk maps
  onto ChatDeltas (content / reasoning_content / tool_calls) which the host
  already prefers over Go-side tag extraction. Without structured messages the
  plain path (LocalAI templating + optional GBNF grammar) applies unchanged.
- The engine resolves the chat template from the GGUF tokenizer.chat_template
  metadata (or tokenizer_config.json); templates beyond its minja subset -
  e.g. the full Qwen3.5 namespace()/macro template - degrade engine-side to a
  Hermes-aware fallback prompt (tools schemas + <tool_call> instruction) with
  a stderr witness, so structural-tag engagement keeps working.
- Importers now emit the same config shape as llama-cpp for vllm-cpp
  (use_tokenizer_template: true, no-grammar autoparser flow); only the
  llama-cpp-specific use_jinja option and the vllm-python parser options are
  dropped.
- Pin bumped to mudler/vllm.cpp@aaed7ec (ABI v3 + chat-prompt resolution).

Verified against the real engine and Qwen3.5-2B-UD-Q8_K_XL.gguf on CPU: full
suite green - blocking chat, streaming deltas concatenating byte-equal to the
blocking answer, a REQUIRED tool call returning schema-valid arguments JSON,
and an AUTO run where the engine itself engages get_weather and streams parsed
tool deltas; plus unit specs for the request lowering, chunk->ChatDelta
mapping, and the C struct mirrors (ABI gate now v3).

* feat(vllm-cpp): ABI v5 - engine-side parser selection for 30 tool dialects + reasoning

Bump the vllm.cpp pin to the autoparser-parity engine: 30 tool-call dialects
(every pure-text parser in the pinned vLLM registry, each ported 1:1 with its
upstream tests), 7 reasoning parsers, google/minja as the template renderer
(the full Qwen3.5 template now renders engine-side), per-family structural
tags (tool_choice required/named compiles the model's NATIVE syntax where
expressible), and template auto-detection for both parser axes.

Backend changes:
- cModelParams mirrors ABI v5 (tool_parser + reasoning_parser fields,
  layout-locked by the offset tests; ABI gate now v5).
- New model options tool_parser:<name> / reasoning_parser:<name> pass through
  to the engine; unset means template auto-detection (18-row tool marker
  table; [THINK]->mistral, <think>->think_auto for reasoning); "none"
  disables the reasoning split; unknown names fail the first chat call.
- Chat chunks parse the `reasoning` field (the pin renamed
  reasoning_content), flowing into ChatDelta.ReasoningContent which the host
  already prefers.

Live e2e against Qwen3.5-2B-UD-Q8_K_XL.gguf on CPU, full suite green: the
real chat template renders (no more fallback), reasoning auto-detection picks
think_auto so markerless answers stay pure content (the live run caught the
deepseek_r1 content-swallow upstream and drove the think_auto fix), required
tool_choice returns schema-valid arguments, auto tool_choice engages
engine-side and streams parsed deltas, and blocking/streaming stay
byte-identical. Turn latency also dropped (proper template EOS behavior).

Upstream program landed as mudler/vllm.cpp 86013f3..5fffe7e (ABI v2-v5,
minja, parser waves B1/B2/B4, reasoning seam, structural-tag registry,
think_auto).

* chore(vllm-cpp): bump the engine pin to the ENG-wave close-out

mudler/vllm.cpp@df8909b: the six engine-backed vLLM tool-parser families
(qwen3-coder/xml/mimo, kimi_k2, glm45/47, minimax_m2, gemma4, seed_oss)
text-reimplemented from their wire formats and held to the upstream test
suites - 39 registered dialects; the pinned vLLM registry is now covered
except the three Rust/Harmony-backed families, descoped by decision. kimi_k2
also gains a full native structural-tag builder; four new template
auto-detection rows land with test-pinned ordering.

Full backend e2e re-run green against Qwen3.5-2B-UD-Q8_K_XL.gguf on CPU.

* fix(vllm-cpp): add the vllm-cpp-development gallery meta

The gallery grew the twelve latest/development image entries but was missing
the separate vllm-cpp-development meta (own capabilities map targeting the
-development image names), which every backend ships so the development
gallery resolves per-platform. Validated: all capability targets in both
metas resolve to existing entries, and every image URI's tag suffix matches
a backend-matrix build.

Also full-stack verified in this change's context (single-node local-ai from
this branch, locally-built backend under --backends-path, Qwen3.5-2B GGUF):
/v1/chat/completions non-stream (clean content + usage), streaming (SSE
deltas), tool_choice auto engaging get_weather engine-side with schema-valid
arguments and finish_reason=tool_calls, and streamed tool-call deltas in the
standard name-first cadence.

* fix(vllm-cpp): repair the CI backend builds - gcc-14 -Werror + fat-arch Triton

Two distinct failures took down all five vllm-cpp backend builds on the PR:

1. gcc-14 (ubuntu:24.04 CI images; the local toolchain is gcc-13) fails the
   engine build with -Werror=maybe-uninitialized in InputBatch::condense - a
   false positive through a staging std::optional's raw storage. Fixed
   upstream (mudler/vllm.cpp@61f3e85) by moving slot-to-slot directly;
   verified BOTH ways under dockerized g++-14.2 (unfixed reproduces CI's two
   diagnostics exactly, fixed compiles clean) with the engine's behavior
   suites green. Pin bumped to that sha.

2. The amd64 CUDA builds died at CMake configure: the vendored Triton-AOT
   cubin trees are per-arch and the engine refuses -DVLLM_CPP_TRITON=ON on a
   multi-arch (120a;121a) fat build unless pinned to one tree, which would be
   unsound for the other arch. Triton is now enabled only on the single-arch
   arm64/GB10 build (where the cubins matter); the fat amd64 binary uses the
   engine's non-AOT GDN path.

Backend e2e re-run green at the new pin (Qwen3.5-2B on CPU, full suite).

* fix(vllm-cpp): cuda-12 images cannot compile compute_121a - target 120a only

The second CI round surfaced a CUDA-version constraint: the cuda-12 (12.8)
image's nvcc rejects 'compute_121a' (GB10 arch support landed with CUDA 13),
killing the amd64 cuda-12 build at nvcc. Gate the architecture list on
CUDA_MAJOR_VERSION (exported by Dockerfile.golang): cuda-12 builds consumer
Blackwell 120a only, cuda-13 keeps the 120a;121a fat binary, arm64/l4t
(cuda-13) keeps single-arch 121a with the Triton cubins. GB10 is arm64, so
the amd64 cuda-12 image never served it - no capability change.

Verified by Makefile dry-run variable dumps for all three combinations
(cuda12 -> 120a; cuda13 -> 120a;121a; cpu -> CUDA off).

* fix(vllm-cpp): drop the cuda-12 variant - the engine needs the CUDA 13 toolchain

Third CI round, third layer: with the arch list already narrowed to 120a,
the cuda-12 (12.8) build still dies in ptxas compiling the sm_120a NVFP4 MMA
kernels ("Vector type too large, exceeds 128 bit limit") - the Blackwell fp4
path genuinely requires the CUDA 13 toolchain, and vllm.cpp supports
Blackwell-family GPUs only. Shipping a cuda-12 image without the fp4 kernels
would be a crippled build of an engine whose whole GPU story is fp4, so the
variant is dropped instead:

- backend-matrix: cuda-12 vllm-cpp entry removed (cuda-13 amd64, l4t arm64,
  cpu, vulkan, metal remain).
- gallery: cuda12 image entries removed; the nvidia capability now resolves
  to the cuda13 image in both metas; the nvidia-cuda-12 key is dropped so
  older-driver hosts fall back to the CPU image instead of an unrunnable one.
- backend Makefile: BUILD_TYPE=cublas under CUDA_MAJOR_VERSION=12 now fails
  fast with a clear message; cuda-13 keeps the 120a;121a fat binary and
  arm64/l4t keeps 121a with the Triton cubins.

Verified: Makefile branch dumps for all four combinations (cuda12 loud
error, cuda13 fat, arm64 121a+Triton, cpu off), YAML parses, matrix filter
tests green, gallery capability targets all resolve.

* fix(vllm-cpp): forward multi-turn tool identity and reasoning to the engine

chatRequestJSON dropped Message.ToolCallId and Message.Name on role="tool"
replies and Message.ReasoningContent on assistant history, so a second
turn after tool execution reached the engine's chat template without the
fields that bind a tool result to the call it answers. Forward all three
(present-only, matching the OpenAI wire shape) and pin vllm.cpp to
6a0bd3e7, where ChatMessage parses/round-trips tool_calls, tool_call_id,
name and reasoning and the minja adapter exposes them to the template
context.

Adds the round-trip request-lowering spec (user -> assistant tool_call ->
tool reply -> lowered request) and re-ran the gated e2e suite against the
new engine pin with a real Qwen3.5 GGUF: chat, reasoning split, streaming
parity, required-tool and auto-tool cases all green.

CPU-quant files on macOS and hit their Linux-only <asm/hwcap.h> /
<sys/auxv.h> includes. vllm.cpp 9e1c9025 detects i8mm per-OS (auxv on
Linux, sysctl on Apple Silicon) with kernels untouched. Gated e2e suite

The macOS runners have no nproc, so JOBS evaluated empty and
`cmake --build -j$(JOBS)` became bare `-j`: unlimited clang jobs on a
3-core/7GB Mac, which swap-thrashed until the 6h GHA timeout (the log
shows "nproc: Command not found" and 7+ concurrent clang processes being
reaped at the cutoff). Use the same portable fallback chain as the other
darwin backends: nproc, then sysctl hw.ncpu, then 4.

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.

8eb8376596 fix(ci): dedup the three workflows that stack runs on every PR push (#11058)
build-test.yaml, yaml-check.yml and secscan.yaml had no concurrency block at
all, so every push to a PR stacked another full batch instead of superseding
the previous one. build-test carries a macos-latest job, the scarcest runner
class we use, and secscan fires on every push to every branch because its
`push:` trigger is unfiltered.

build-test and yaml-check use the same group idiom as lint.yml and the other
eleven workflows that already have one: key on the PR number so pushes to a PR
share a group, and cancel only on pull_request. On a master push the key falls
back to github.sha and cancel-in-progress is false, so master runs never cancel
each other -- that is deliberate, since backend.yml builds only the backends a
given commit touched and superseding would drop those builds.

secscan needs a different key: it has no pull_request trigger, so the shared
idiom would fall back to the unique-per-commit sha and dedup nothing. It groups
on github.ref instead, and excludes master from cancellation for the same
per-commit reason. Cancelling a superseded feature-branch scan is safe because
the only output is a SARIF upload and code scanning keeps the latest result
per ref.

No behaviour change on master for any of the three.

47c0e06198 fix(ci): authenticate the nightly dependency-bump API calls (#11042)
The "Bump Backend dependencies" workflow has failed every night for the
last two weeks. #11012 fixed one cause (repos renamed under localai-org);
what is left is rate limiting.

bump_deps.sh fans out to ~25 parallel matrix jobs that each query
api.github.com anonymously. Anonymous calls are capped at 60/hour per
source IP and GitHub-hosted runners egress through shared NAT addresses,
so a random handful of jobs draw HTTP 403 and die at curl exit 22 with an
empty response. Last night that hit ggml-org/whisper.cpp and
mudler/depth-anything.cpp -- both public and resolvable, nothing wrong
with either pin.

Route every bump script through a shared gh_curl helper that sends
GITHUB_TOKEN when present (1000/hour instead of 60) and retries transient
failures, including the 403s that plain --retry ignores. The helper
suppresses xtrace around the call so the Authorization header cannot land
in a public job log.

bump_docs.sh had a sharper version of the same bug: it piped an
unchecked response into `jq -r .tag_name`, so a throttled request
resolved to the string "null" and would have been published as the docs
version. It now refuses to write anything it cannot resolve to a tag.

Verified locally by running all four scripts end to end against their
real upstreams: correct SHAs/tags written, exit 0; a nonexistent repo now
fails with a named diagnostic instead of a bare exit 22 and leaves the
pinned file untouched; the token is absent from the xtrace output; and
the scripts still work unauthenticated.

* ci(apexentries): build the HF client via pkg/httpclient

The apexentries HuggingFace client was constructed as a raw
&http.Client{Timeout: 60s}. The repo convention (documented in
.golangci.yml, which cannot express this as a forbidigo pattern) is that
all outbound HTTP goes through pkg/httpclient, which refuses redirects by
default and sets a TLS 1.2 floor. The std client follows redirects and
forwards custom credential headers to the redirect target on a cross-host
hop (GHSA-3mj3-57v2-4636). Only a User-Agent is sent today, but this
calls an external API and an HF_TOKEN header added later would leak.

Switch to httpclient.NewWithTimeout, preserving the 60 second timeout.
No behaviour change for the current header set.

* ci(apexentries): set backend, known_usecases and cross-repo drafters

RenderChild left three gaps against the hand-written gallery entries.

The generated entries reference gallery/virtual.yaml, which supplies no
backend, so every generated entry named no engine at all. All comparable
hand-written entries set backend: llama-cpp in overrides; do the same.
Set known_usecases to [chat] alongside it: LocalAI falls back to the
backend defaults when it is absent, so this is convention rather than
breakage, but generated entries should not read differently from their
neighbours.

The drafter was also assumed to live in the repo publishing the weights.
Speculative pairings routinely cross repos, and a drafter URI built from
the weights repo 404s at install time. Add ChildInput.DraftRepo, used for
both the drafter URI and its local path, falling back to Repo when empty
so pairings that do ship the drafter alongside the weights are unchanged.

The dflash/mtp tagging rule is untouched: the tag still follows SpecType
and nothing else.

* apexentries: canonicalize HF URIs and dedup the generated batch

Merge exists to stop a second gallery entry being added for weights the
gallery already ships, but two gaps let duplicates through on a bulk run.

The URI key was compared as an exact string while render.go only ever emits
https://huggingface.co/{repo}/resolve/main/{file} and the gallery records
1038 of its URIs in huggingface://{repo}/{file} shorthand. A generated
unsloth rung whose weights are already shipped in shorthand was therefore
not recognised. canonicalURI reduces both spellings to one key and is
applied on both sides, taking care that the repo is exactly the first two
path segments so sharded quants in a subdirectory still match. A URI in
neither form is returned untouched so other hosts dedup on their literal
string.

Merge also never accounted for entries it had just accepted, so two
generated entries sharing a name or a primary URI both landed in add.
Several APEX repos share one base model and resolve to the same unsloth
counterpart, so the identical rungs are generated twice under the same
name. Batch state is tracked locally rather than written back into the
caller's ExistingIndex, which a caller may reasonably reuse.

Name is still checked before URI: a name collision must block the add
regardless of the weights.

* fix(ci): scope the apex-entries verifier to what it can actually judge

The verifier reported 60 problems against the real gallery, 57 of which were
llama.cpp assumptions meeting entries from other backends. A gate that is wrong
57 times out of 60 cannot gate anything.

- The weight-count check catches a quant label collision in llama-cpp quant
  discovery, so it now runs only for overrides.backend: llama-cpp. Entries with
  no declared backend are skipped because their weights are declared in the
  referenced url: template, which the verifier never reads.
- The dflash/mtp tag check now implements the per-backend table in
  .agents/adding-gallery-models.md instead of assuming llama.cpp's spec_type:
  vocabulary. ds4 declares mtp_path:/mtp_draft:; sglang declares
  speculative_algorithm: in a file this verifier cannot follow, so sglang
  entries are not judged in either direction. The check stays bidirectional
  within the backends it does judge.
- sha256 is now required on .gguf files only, since every non-GGUF asset in the
  index belongs to a hand-curated entry outside this generator's scope.

Against the current gallery this leaves exactly the three genuine problems:
two entries setting spec_type:draft-mtp without the mtp tag, and one entry
whose overrides.mmproj names a file it does not download.

* ci(apexentries): anchor quant matching and invert the sha256 rule

UnaccountedQuants matched files to wanted quants with strings.Contains, which
reproduces the substring collision it was written to warn about: Q8_0 is a
substring of UD-Q8_0, so a repo publishing only UD-Q8_0 was reported as
publishing an unbuilt Q8_0. Subdirectory-sharded UD quants are the normal
unsloth layout for large repos, so this fired on realistic input.

Match on the quant label as an anchored token instead, the way
DiscoverUnslothQuants does, so the diagnostic and the discovery it audits
cannot disagree about what a file is. Root-level shards, the layout the
diagnostic mainly exists to catch, stay detected.

The sha256 requirement was scoped to .gguf, which exempted seven real model
weights: wan_2.1_vae.safetensors and clip_vision_h.safetensors across the
wan-2.1-*-ggml entries, both load-bearing weights named by gallery/wan-ggml.yaml.
Invert the rule so a checksum is required on everything except metadata
extensions, which keeps a future weight format covered by default rather than
silently exempt.

* feat(ci): wire the apexentries command

Adds the generation path to the apexentries command: list the mudler APEX
repos, discover each one's quality ladder and its unsloth counterpart's quant
rungs from the filenames actually published, render a child entry per build
plus a family parent carrying the variants list, dedup against the gallery,
and write the additions to -out or append them with -apply.

Discovery shortfalls are reported at discovery time rather than left to the
verifier. A quant or a tier that discovery drops leaves no trace in a finished
gallery file, and because an empty imatrix ladder falls back to the plain one,
a repo whose imatrix filenames all fail to match downgrades the whole family
silently instead of erroring.

Merge's single reused map is split into two reported categories. A URI match
means the gallery already ships exactly these weights and referencing the
existing entry is correct; a name collision means an unrelated entry owns the
name and referencing it would substitute a different build.

Multimodal children now declare known_usecases [chat, vision]. An explicit
known_usecases suppresses the backend-default fallback, so a chat-only entry
carrying an mmproj never matches the vision or multimodal gallery filters.

.github/ci is invisible to go list ./..., so a workflow names both generator
packages explicitly and their specs finally run on pull requests.

* feat(ci): gather APEX builds under the base model entry

The hub for a family is the BASE model entry, never a generated *-apex
parent. Somebody looking for qwen3.6-35b-a3b has to find every build of
those weights under that one name, so a competing qwen3.6-35b-a3b-apex
hub would split the family and leave half of it invisible.

When the gallery already ships the base entry, a variants block is
spliced into it textually, leaving its description, icon, tags,
overrides and files untouched. Only a family whose base model the
gallery does not ship gets a new hub, still named for the base model and
carrying one of the discovered builds as its own payload so it declares
a backend the verifier can judge.

The line editing is factored into .github/ci/galleryedit, shared with
the variantproposals job, so the two cannot drift apart on where a
variants block belongs.

* fix(apexentries): treat an unreadable optional counterpart repo as absent

HuggingFace answers 401 Unauthorized, not 404, for a repository that does
not exist when the request carries no credentials. FetchRepoFiles treated
only 404 as absence, so probing for the OPTIONAL unsloth counterpart hard
failed for every family that legitimately has none: 27 of the 45 APEX
families are community merges that will never have an unsloth build, and a
full run failed all of them.

Split the fetch so the two call sites can apply different policies to the
same response. The APEX repo itself stays strict: a 401 or 403 on a repo
the run requires is a real failure and still errors. Only the optional
probe tolerates it, because without a token 401 cannot be told apart from
absence.

That collapse is lossy in one direction, since a private or gated repo also
answers 401, so the skipped candidates are named in the run summary
alongside the other silent-shortfall counters instead of being dropped in
silence.

* ci(apexentries): report full-precision sources as a known exclusion

The 45 APEX repos publish their unquantized F16 sources next to the
imatrix ladder, flat or sharded. Discovery correctly emits nothing for
them, but they were landing in the unclassified total, leaving a
permanent baseline of 24 benign lines on every run.

That baseline is what the unclassified check exists to prevent: a
standing count of known-benign files is exactly what hides the one file
that ever genuinely matters. Count full-precision sources separately and
give them their own summary line, so unclassified returns to 0 and stays
loud when something really is an unknown shape.

* fix(apexentries): namespace local paths by owner and enable MTP builds

localPath namespaced downloads by the repo basename alone, so two repos
publishing the same filename under different owners collapsed to one local
path. LiquidAI/LFM2.5-8B-A1B-GGUF and unsloth/LFM2.5-8B-A1B-GGUF collided that
way, and both were offered from the same hub, so installing the second either
overwrote the first model's weights or was skipped as already present while
recording a sha256 that did not match the bytes on disk. The owner is now its
own path segment: owner/repo is globally unique on HuggingFace and neither half
can contain a separator, so uniqueness holds by construction.

Verify gains a check for the whole class, that no local filename may map to two
different upstream URIs. It surfaces seven pre-existing collisions in the
gallery, which are left alone here.

Entries built from the *-APEX-MTP-GGUF repos now configure MTP rather than
shipping the heads inert, matching the pattern the hand-written MTP entries
already use: spec_type:draft-mtp with spec_n_max and spec_p_min, tagged mtp, and
no draft_model because the heads live in the weights. RenderChild no longer
requires a separate drafter file before it will configure a spec type, while the
cross-repo drafter path is unchanged.

* feat(gallery): add the APEX GGUF families as variant ladders

Adds the imatrix quality ladder from each mudler/*-APEX-GGUF repo, a fixed
subset of unsloth quant rungs where a counterpart repo exists, and the MTP
builds, then attaches them to the base model entry so one entry offers every
build of the same weights and LocalAI picks the one that fits the hardware.

Ten existing base model entries gain a variants list; twenty-seven families that
the gallery had no base entry for get one. Builds are discovered from the
filenames each repo actually publishes rather than derived from its name, since
six repos ship a stem that differs from their repo name. Every file carries a
sha256 taken from the HuggingFace API.

1e0baec2a7 fix(ci): repair nightly backend dep bumps for renamed localai-org repos (#11012)
The "Bump Backend dependencies" workflow has failed every night for over
ten days. Four upstreams — ced.cpp, moss-transcribe.cpp, voice-detect.cpp
and rf-detr.cpp — moved from the mudler org to localai-org, so the GitHub
API answers 301 for the old slugs. ced.cpp additionally renamed its
default branch to main.

bump_deps.sh fetched without -L or -f and never checked the response, so
the redirect's JSON body was passed straight to sed, which died with
"unterminated `s' command". The loud failure was luck: an error body
without slashes would have been substituted into the Makefile as the new
pin, silently corrupting the version and shipping it in a bump PR.

Point the matrix at the new slugs and branch, and harden the script so a
bad response can never reach sed: follow redirects, fail on HTTP errors,
and require a bare 40-hex SHA before rewriting anything. Also refresh the
now-stale repository URLs in the backend Makefiles, test scripts,
backend/index.yaml and the docs.

Verified all 25 matrix entries resolve to a commit SHA and that the four
previously-failing jobs run end to end against the real API.

0cdd781c2d ci(gallery): propose variant groupings for review instead of letting them decay (#10992)
ci(gallery): propose variant groupings for review on a schedule

A gallery entry may declare `variants:`, references to other entries that
are alternative builds of the same weights, and auto-selection then installs
the best build for the host. Those families exist only because humans curated
them in two manual sweeps.

The gallery agent dedupes on the HuggingFace repo URL and picks one
quantization per model, so it never adds a second build of a repo it already
has, and consequently never creates a family and never joins one. A model
published across two repos lands as two unrelated standalone entries. The
grouping decays as the gallery grows and nothing notices.

Add a scheduled job, in the same shape as the checksum checker: compute
offline, edit the index textually, open a pull request against ci-forks. It
proposes and never decides. Grouping is a judgement call that has gone wrong
in both directions, so the value is catching drift and surfacing candidates
with their evidence.

Three grouping signals, taken from the manual sweeps: same name once
quantization markers are stripped, the `:` config-suffix convention, and the
same primary weight filename once quantization markers are stripped. The
third requires the same upstream repository. Excluding auxiliary files is not
enough on its own: bert-embeddings, an ultravox audio model and a roleplay
finetune all declare a primary file called llama-3.2-1b-instruct-q4_k_m.gguf,
and grouping on that is the same error that linked four wan-2.1 entries and
Z-Image-Turbo to qwen3-4b.

Add gallery/variant-exclusions.yaml, a checked-in rejection ledger. A job
that re-proposes declined candidates every night becomes noise and gets
ignored. Declining a proposal is one flow-mapping line a reviewer adds inside
the proposal pull request itself. Seeded with the six -abliterated pairs whose
base is also in the gallery, the mistral-small multimodal pair, the whisper-1
alias, the kokoros language set, and the recurring finetune tokens. qat and
apex are deliberately not on it: they are quantization techniques.

Proposals refuse to nest, to let two parents claim one target, to target an
entry that installs nothing, and to touch a merge anchor, since a variants key
added to an anchor is inherited by every merging child. The anchor refusal
names every entry that would inherit, which is the worklist a human needs.

Run against the pre-sweep gallery, the job rediscovers 12 of the 19 groupings
the second manual sweep made, with no false positives. The rest it reports as
refusals or ledger declines rather than missing silently.

6e52d0c2ef fix(ci): rebuild backends when shared build inputs change (#10975)
The backend matrix path filter only matched files under a backend's own
directory, so a change to shared build infrastructure rebuilt nothing at
all: an empty matrix, every job green, and the change reaching no image.

PR #10946 fixed scripts/build/package-gpu-libs.sh shipping a partial
4-of-8 cuDNN library set, which mixed versions with the venv's pip cuDNN
and produced CUDNN_STATUS_SUBLIBRARY_VERSION_MISMATCH at inference time.
It merged 1h48m after the weekly full-matrix cron had already run, so no
backend image ever received the fix and nothing signalled that it had
been un-shipped.

Add a SHARED_BUILD_INPUTS table mapping each shared path to the narrowest
set of matrix entries it can honestly invalidate, plus a generic rule for
backend/Dockerfile.<x> (which each entry already names). A full matrix is
417 Linux + 56 Darwin builds, so package-gpu-libs.sh now rebuilds the 176
Python entries rather than everything. Unclassified files under
scripts/build/ fall back to a full rebuild deliberately: over-building is
recoverable, silently shipping nothing is not.

Extract the filtering logic to scripts/lib/backend-filter.mjs so it can be
unit-tested without bun, js-yaml or a GitHub API round-trip, and run those
tests from the existing lint workflow via `make test-ci-scripts`.

963c637130 fix(gpu-libs): bundle cuDNN only where it is used, and complete it when it is (#10946)
cuDNN 9 is a dispatcher (libcudnn.so.9) plus seven sublibraries the dispatcher
dlopen()s by bare soname. Only the dispatcher is ever a DT_NEEDED, so ldd finds
it and never the seven. The allowlist force-copied three of them
(libcudnn.so*, libcudnn_ops.so*, libcudnn_cnn.so*) into every CUDA backend,
which is wrong in both directions at once: too few libraries for a backend that
uses cuDNN, and too many for one that does not.

On an L4T fleet, ten of the eleven backends carrying cuDNN were in a broken end
state; the one that was correct was correct by accident, being BUILD_TYPE=cpu
so package_cuda_libs never ran for it.

  longcat-video bundled 4 of 8 at 9.24.0 over a complete pip set at 9.20.0.48
  in its venv. libbackend.sh puts lib/ on LD_LIBRARY_PATH, searched before
  DT_RUNPATH, so the bundle won and the rest still came from the venv:
  CUDNN_STATUS_SUBLIBRARY_VERSION_MISMATCH.

  Nine others bundled 3 of 8 and had no venv cuDNN. None bundled
  libcudnn_graph, which libcudnn_cnn has a hard DT_NEEDED on, so it resolved
  out of the runtime image and the process ran bundled 9.22.0 against system
  9.23.2.

Five of those nine - llama-cpp, whisper, rfdetr-cpp, sam3-cpp,
stablediffusion-ggml - do not reference cuDNN at all. ggml goes through cuBLAS.
They were carrying ~57 MB of cuDNN with no consumer, and completing the family
for them would have taken that to ~576 MB for nothing.

Sizes overall: backends with no cuDNN consumer shed ~57 MB each (seven
instances on the fleet measured, plus longcat's ~60 MB), while the ones that
genuinely use cuDNN grow from ~57 MB to ~576 MB, because the five missing
sublibraries are ~517 MB, dominated by libcudnn_engines_precompiled. Net on
that fleet is an increase of roughly 570 MB. That growth is the bug being paid
off, not a regression: those backends only work today by silently borrowing the
missing five from the runtime image. Whether the engines set can be trimmed is
an open question, not addressed here.

So bundle per backend, by what that backend actually needs:

  - venv has a complete pip cuDNN -> bundle nothing; $ORIGIN resolves the pip
    set, which is the one its torch was built against            (longcat-video)
  - venv has no pip cuDNN         -> bundle the complete family. Stays
    conservative rather than detecting consumers: for a Python backend they sit
    inside the venv (torch, ctranslate2, onnxruntime) where the sweep does not
    look                                                                 (vllm)
  - no venv, nothing references cuDNN -> bundle nothing    (llama-cpp, whisper,
                                     rfdetr-cpp, sam3-cpp, stablediffusion-ggml)
  - no venv, something references it   -> bundle the complete family
                                                  (face-detect, voice-detect)

The no-venv case needs no new machinery. Go backends stage their own shared
object into package/lib, which IS the target dir, so sweep_transitive_deps
already pulls the dispatcher when it is a genuine dependency - that is exactly
how libcudnn_graph reached longcat. cuDNN simply comes off the force-copy list,
and complete_cudnn_family fills in the seven dlopen'd sublibraries around
whatever the sweep found. Detection is a string scan rather than ldd, so a
consumer that only dlopen()s cuDNN is seen too; over-matching costs an unused
library, under-matching costs a backend that cannot load.

Keeping bundled and pip versions in agreement instead is not viable: nothing
here pins nvidia-cudnn (zero occurrences), torch is unpinned for l4t13 except
longcat-video, and the fleet already runs five concurrent cuDNN versions -
9.19.0.56, 9.20.0.48, 9.22.0, 9.23.2, 9.24.0.

verify_cudnn_bundle asserts the end state: exactly one complete cuDNN visible to
whoever needs one - never both, never partial, and never zero for a backend that
references it. Zero is correct and common otherwise. It deliberately does not
accept the build image's system cuDNN as completing a partial bundle, which is
the shape that had been shipping silently; the build image is not the runtime
image. A version check alone would have missed longcat too, whose four bundled
libs were all 9.24.0 and mutually consistent.

Match per family for the other components for the same dlopen reason: TensorRT
(libnvinfer_plugin, libnvinfer_builder_resource), cuBLAS, cuFFT, cuSPARSE,
cuSOLVER, nvRTC. Exclusions bind inside copy_lib so they cover the sweep.

The packaging scripts' shell tests ran nowhere in CI. Add make
test-build-scripts and a lint workflow job so they gate every PR.

Fixes #10905

bbe018c1a0 feat(bonsai): PrismML llama.cpp fork backend + Bonsai/Ternary-Bonsai gallery models (#10834)
feat(bonsai): add PrismML llama.cpp fork backend + Bonsai gallery models

Adds a new `bonsai` backend that runs the PrismML fork of llama.cpp
(github.com/PrismML-Eng/llama.cpp, `prism` branch), which ships the Q1_0
(1-bit) and Q2_0 (ternary / 1.58-bit) weight-quantization kernels used by the
Bonsai and Ternary-Bonsai models. Stock llama.cpp cannot decode these quants.

Modeled on the turboquant backend: reuses backend/cpp/llama-cpp/grpc-server.cpp
against the fork's libllama via a thin wrapper Makefile, so the sub-2-bit models
are served with the same OpenAI-compatible API. No grpc-server allow-list patch
is needed (bonsai adds weight quants, transparent to the server, not KV-cache
types), and the reused server compiles cleanly against the fork with no skew
patches (validated locally via a CPU docker build; patches/ is present but empty
for any future re-pin skew).

Backend wiring: backend/cpp/bonsai/, .docker/bonsai-compile.sh,
backend/Dockerfile.bonsai, top-level Makefile targets, backend-matrix.yml build
rows (CPU, CUDA 12/13, L4T, SYCL f32/f16, Vulkan, ROCm/hipblas), backend/index.yaml
meta-backend + per-platform images, and a nightly bump_deps entry tracking the
`prism` branch.

Gallery: 8 entries across 4 families - bonsai-8b-1bit, ternary-bonsai-8b (+g64,
+pq2), bonsai-27b-1bit (vision), ternary-bonsai-27b (+pq2, +g64, vision). The 27B
models wire the mmproj vision tower; the DSpark speculative drafter GGUFs are not
wired (custom semi-autoregressive drafter, not a standard llama.cpp draft model).

29db4ab414 fix(ci): shard single-arch backend matrix under GitHub's 256-job limit (#10703)
GitHub Actions refuses to instantiate a matrix that would generate more
than 256 jobs. It does so silently: the job hangs forever at "Waiting for
pending jobs" and the whole run is marked `failure` while every other job
stays green. This is exactly what happened on the v4.6.1 tag build
(run 28786533892): the single-arch build matrix had grown to 268 entries,
so `backend-jobs-singlearch` (and its downstream merge) never produced a
single job, and the release build "failed" with no failing job to point at.

The single-arch list is the one that grows unbounded as backends are added,
so shard it across a fixed number of matrix jobs (SINGLEARCH_SHARDS=4,
~67 entries each today, headroom to ~1020 backends). Each merge shard
`needs:` only its matching build shard, preserving the "merge waits only on
its own build" property that keeps slow CUDA/ROCm builds from gating
multi-arch manifest assembly.

changed-backends.js now emits per-shard matrix/has-* outputs and throws
loudly if a shard ever reaches the 256 limit (telling the maintainer to
bump SINGLEARCH_SHARDS and add matching job blocks) instead of letting
GitHub drop the overflow silently. backend.yml and backend_pr.yml define
the four build + four merge shard jobs; multi-arch and darwin groups are
untouched.

5d0c43ec6e feat(realtime): Semantic VAD EOU token (#10444)
* feat(realtime): EOU-driven semantic_vad turn detection

Add a `semantic_vad` turn-detection mode to the realtime API that feeds
the transcription model live and decides "the user finished speaking"
from the `<EOU>` end-of-utterance token rather than from silence alone.
When EOU fires the turn commits immediately (~0.3s); otherwise it falls
back to an eagerness-scaled silence threshold (low/med/high = 8/4/2s).

Plumbing, bottom to top:

- proto: `AudioTranscriptionLive` bidirectional RPC (config-first oneof,
  mono float PCM @16k, ready-ack / Unimplemented degrade signal) plus
  `TranscriptResult.eou` for the unary retranscribe gate.
- pkg/grpc: client/server/base/embed scaffolding for the bidi stream,
  modeled on AudioTransformStream; release stream conns on terminal Recv.
- parakeet-cpp: live transcription RPC with per-C-call engine locking
  (one live stream per turn, finalize+free at commit); bump parakeet.cpp
  to ABI v5 — incremental StreamingMel (no more quadratic per-feed mel
  recompute that delayed EOU on long turns) and the <EOU>/<EOB> split;
  strip the literal <EOU>/<EOB> from offline text and set Eou.
- core/backend: LiveTranscriptionSession wrapper + pipeline
  `turn_detection:` config block (type/eagerness/retranscribe).
- realtime: semantic_vad integration — live input captions streamed as
  transcription deltas while the user speaks, EOU-immediate commit with
  eagerness fallback, optional retranscribe gate (batch re-decode must
  also end in <EOU> to confirm), clause synthesis off the LLM token
  callback, and per-turn live-transcription / model_load telemetry.
- UI: show the realtime pipeline components as a vertical list.

Docs and tests included; opt-in via the pipeline YAML or per-session
`session.update`. Non-streaming STT backends degrade to silence-only.

* feat(realtime): explicit formally-verified state machines + parakeet streaming driver

The realtime API had several implicit state machines whose state was inferred
from scattered booleans, channels, and five separate mutexes, leaving
illegal/inconsistent states reachable. Make them explicit and keep the
implementation in step with a formal design; rework the parakeet streaming
backend along the same lines.

Realtime state machines (M1-M5). Each is a sealed sum-type State/Event/Effect
with a total, pure Next(state,event)->(state,[]effect) behind a single-writer
Coordinator:

  M1 conncoord    connection lifecycle: VAD toggle + once-only teardown
                  (replaces vadServerStarted + a `done` channel closed from
                  two sites).
  M2 turncoord    turn detection: collapses speechStarted and the live-stream
                  "turn open" flag into one state, so discardTurn can no longer
                  desync them and suppress the next onset.
  M3 respcoord    response coordination: serializes the dual-writer
                  start/cancel so at most one response is live; one
                  response.done per response.create.
  M4 compactcoord conversation compaction: single-flight (replaces the
                  `compacting atomic.Bool` CAS).
  M5 ttscoord     TTS pipeline: open->closing->closed, idempotent wait(),
                  rejects enqueue-after-close (was a silent drop).

The Coordinator/Sink/Next plumbing — only the sealed types and Next differed
per machine — is extracted once into core/http/endpoints/openai/coordinator as
a generic Coordinator[S,E,F]; each machine keeps its public API via type
aliases, so no sink, call-site, or test moved.

Hierarchy. session_lifecycle.fizz models M1 as the parent region with its
children (M2/M3/M4) as one statechart and asserts ChildrenDieWithParent (conn
torn => all children terminal, none start after teardown). respcoord and
compactcoord gain an absorbing Terminated state + Shutdown event; conncoord's
teardown drives the children terminal. This closes a compaction teardown gap: a
fire-and-forget compaction could outlive a torn session — compactionSink now
takes a session-scoped cancellable context + WaitGroup and joins the in-flight
summarize+evict on shutdown.

Formal verification. formal-verification/ holds one authoritative FizzBee spec
per machine plus the composition spec, each with an always-assertion and a
documented one-line edit that makes the checker fail (verified non-vacuous).
scripts/realtime-conformance.sh is fail-closed: all Go conformance suites under
-race AND a model-check of every .fizz spec; a missing FizzBee is a hard error
(only the loud REALTIME_CONFORMANCE_SKIP_FIZZBEE=1 bypasses it, never in CI).
FizzBee is pinned by sha256 and installed via scripts/install-fizzbee.sh into
.tools/ (gitignored). Wired as make test-realtime-conformance, a CI workflow,
and a pre-commit path filter. Go conformance tests are Ginkgo/Gomega (per the
repo's forbidigo lint): transition tables + fixed-seed property walks +
concurrent/-race specs, no rapid dependency. Design map:
docs/design/realtime-state-machines.md.

Parakeet streaming backend. The same treatment applied to the parakeet-cpp
streaming paths:
- AudioTranscriptionStream returns codes.Unimplemented for non-streaming models
  instead of decoding offline and emitting it as one delta + final. A client
  that asked for streaming learns the model cannot stream rather than receiving
  a batch result shaped like a stream. New grpcerrors.StreamTranscriptionUnsupported
  carries that signal; the HTTP /v1/audio/transcriptions stream path surfaces it
  as an SSE error event. Mirrors AudioTranscriptionLive, which already did this.
- utteranceBoundary (boundary.go): a single definition of the end-of-utterance
  latch, replacing three open-coded finalEou toggles. Modelled as a two-valued
  type so illegal states are unrepresentable.
- Shared decode driver (driver.go): streamFeedResult (one per-feed event) +
  feedChunk (hides the ABI v4 JSON vs text-only split) + feedSlices + flushTail.
  The feed loop is written once.
- AudioTranscriptionLive becomes a bidi adapter: it streams the per-feed
  {delta,eou,eob,words} the realtime turn detector consumes and a terminal
  FinalResult carrying only Text. Segments/duration/eou are offline-only and no
  longer produced (nor read) on the live path; liveTraceState drops the terminal
  eou and keeps the per-feed eou_events count.
- AudioTranscriptionStream + streamJSON merge into one driver-based function;
  streamSegmenter is generalized to the unified event with a text-only fallback
  that preserves the legacy (no-words) library's per-utterance segmentation.

Verified: build/vet/gofumpt clean, golangci-lint 0 issues, all coordinator and
parakeet packages under -race, the fail-closed conformance gate green, and
make test-realtime (12 e2e WS+WebRTC).

de2ec2f136 feat(backends): add voice-detect + face-detect ggml backends (replace Python insightface/speaker-recognition) (#10441)
* feat(voice-detect): add Go purego backend for voice-detect.cpp

Add backend/go/voice-detect implementing the Backend gRPC voice subset
(VoiceEmbed/VoiceVerify/VoiceAnalyze) over libvoicedetect.so via purego,
mirroring the parakeet-cpp / omnivoice-cpp backends.

The flat voicedetect_capi C ABI is dlopen'd cgo-less; malloc'd string and
float-vector returns are owned by Go and released through the matching capi
free functions, with the per-ctx last error surfaced into Go errors. Calls are
serialized via base.SingleThread since the C context is not reentrant.

Proto field mapping:
- VoiceEmbed: VoiceEmbedRequest.audio (path) -> embed_path -> Embedding+Model.
- VoiceVerify: audio1/audio2 + threshold (<=0 falls back to the
  verify_threshold option, default 0.25) -> verify_paths -> verified/distance/
  threshold/confidence/model/processing_time_ms.
- VoiceAnalyze: audio (path) -> analyze_path_json; the JSON age/gender/emotion
  document maps to a single VoiceAnalysis segment (start/end 0; gender "label"
  -> dominant_gender with the remaining float scores as the gender map; emotion
  label/scores -> dominant_emotion/emotion).

The Makefile pins voice-detect.cpp to 47546430, clones+builds libvoicedetect.so
with ggml static-linked (PIC, GGML_NATIVE off) so dlopen needs no external
libggml/libvoicedetect; ldd on the artifact shows only system libs. Ginkgo
tests cover option parsing and analyze-JSON mapping; embed/verify smoke specs
gate on VOICEDETECT_BACKEND_TEST_MODEL + VOICEDETECT_BACKEND_TEST_WAV.

* feat(voice-detect): wire backend into index, gallery and build

Register the voice-detect.cpp speaker-recognition + voice-analysis
backend (added in Voice-INT-A) into LocalAI's distribution surfaces,
mirroring the ced backend (the closest mudler C++/ggml audio analogue):

- backend/index.yaml: add the &voicedetect meta-backend (capabilities
  platform map, no top-level uri) plus the full set of concrete per-arch
  image entries (cpu/cuda12/cuda13/metal/rocm/sycl/vulkan/l4t and the
  -development variants). Referential integrity audited - every alias
  target resolves.
- gallery/index.yaml: add 5 model entries on backend voice-detect -
  ECAPA-TDNN, WeSpeaker ResNet34, 3D-Speaker ERes2Net, CAM++ and the
  wav2vec2 age/gender/emotion analyze model. The engine architecture is
  read from GGUF metadata (voicedetect.arch) at load. GGUF artifacts are
  not yet published: each files: entry points at the intended
  mudler/voice-detect-gguf location with a TODO to fill sha256 after
  upload (no fabricated hashes).
- .github/backend-matrix.yml: add the linux build matrix block + the
  darwin metal entry mirroring ced.
- .github/workflows/bump_deps.yaml: track mudler/voice-detect.cpp via
  VOICEDETECT_VERSION (pin 47546430, = 4754643).

* feat(face-detect): add purego Go backend for face-detect.cpp

Add the LocalAI Go backend that dlopens libfacedetect.so (the flat
facedetect_capi_* C-ABI) via purego, mirroring the sibling voice-detect
backend. Implements the Face subset of the Backend gRPC service:

- Embeddings(PredictOptions): Images[0] base64 -> temp file -> embed_path
  -> L2-normalized ArcFace embedding.
- Detect(DetectOptions): src -> detect_path_json -> Detection boxes
  (class_name "face", [x1,y1,x2,y2] -> x/y/w/h).
- FaceVerify(FaceVerifyRequest): two images + threshold + anti_spoof ->
  verify_paths; best-effort img areas via detect.
- FaceAnalyze(FaceAnalyzeRequest): img -> analyze_path_json -> per-face
  age + gender ("M"/"F" normalized to "Man"/"Woman").

The Makefile pins face-detect.cpp to 636a1963 and builds the shared lib
with ggml + vendored libjpeg-turbo static (PIC), so the .so is
ldd-clean (no libggml) and exports only facedetect_capi_* (no jpeg_
symbols). Gated Ginkgo e2e mirrors voice-detect.

Note for the gallery-wiring task: backend registration (index.yaml,
gallery, core/config/backend_capabilities.go) is intentionally not
touched here.

  platform map, no top-level uri to avoid the meta-backend gotcha) plus
  the full set of concrete per-arch image entries (cpu/cuda12/cuda13/
  metal/rocm/sycl-f16/sycl-f32/vulkan/l4t and the -development variants),
  22 entries. Referential integrity audited: every alias target resolves.

read-port bound) and was NOT shipped. Kernel ceiling reached; further gap needs
an algorithm-class change (cache-blocked weight-stationary GEMM, or q8 weights).

* chore(recon): bump pins to GPU persistent-graph + multi-model-safe cache (voice 45d2e6b, face 0a4799a)

GPU wins (CUDA/ggml backend, no CPU-path change): persistent per-shape graph+context
cache in Backend::compute() eliminates the per-call cudaGraph re-instantiation churn
-> wav2vec2 emotion+age-gender now AT GPU parity with torch-cuDNN on GB10 (0.97-0.98x),
CAM++ -5.7ms; bit-identical parity. Cache hardened multi-model-safe (invalidate-on-free
keyed by the ModelLoader weights buffer) so LocalAI multi-model hosting cannot stale-hit.
Conv models still trail cuDNN (im2col-materialization-bound) - cuDNN implicit-GEMM lever next.

Adds the opt-in cuDNN implicit-GEMM conv path (VOICEDETECT_GGML_CUDNN /
FACEDETECT_GGML_CUDNN, DEFAULT OFF -> zero build/runtime dep until enabled).
On GPU it kills the im2col-materialization bottleneck and reaches torch-cuDNN
parity on the spill-bound convs: SCRFD detect 14.8->6.4ms (2.3x, ~parity),
WeSpeaker ~parity, ERes2Net beats torch (1.10x); ArcFace/CAM++ neutral (no
spill). Parity exact (SCRFD <=1px, cosine=1.0). To USE it in LocalAI, the CUDA
backend build must enable the flag AND bundle libcudnn - deferred until a
cuDNN-bundled GPU image; flag stays OFF here.

* feat(recon): enable cuDNN conv path on arm64+CUDA13 recon backends

The voice-detect.cpp / face-detect.cpp engines have an opt-in cuDNN
implicit-GEMM conv path behind VOICEDETECT_GGML_CUDNN / FACEDETECT_GGML_CUDNN
(default OFF) that kills im2col on the GPU and reaches torch-cuDNN parity
(SCRFD 2.3x, WeSpeaker/ERes2Net parity), measured on the GB10
(arm64, CUDA 13, sm_121a).

Enable it for the CUDA build, but only where cuDNN actually ships: the
arm64 + CUDA 13 image (GB10/Jetson/L4T). x86 CUDA images carry no cuDNN,
so flipping it on globally for BUILD_TYPE=cublas would be a link failure.
The Makefiles gate on CUDA_MAJOR_VERSION=13 + arch (TARGETARCH from the
matrix/Docker build, uname -m fallback for local builds).

backend/Dockerfile.golang already installs the runtime libcudnn9-cuda-13
in the arm64+CUDA13 apt block; add the matching libcudnn9-dev-cuda-13 so
the build-time link resolves.

mul_mat is AVX2-only) this wins ~2x at every thread count (2.07x@1t, 2.2x@4t,
2.05x@8t); pure-AVX2 fallback still 1.3-1.62x. Parity exact (cosine=1.000000 vs

fdff114701 ci(vibevoice): skip the ASR transcription e2e on release tag builds (#10567)
The `tests-vibevoice-cpp-grpc-transcription` job downloads the vibevoice ASR
model (`vibevoice-asr-q4_k.gguf`, ~10 GB) and decodes it through the
e2e-backends harness. On release tag pushes the detect step forces the full
matrix (run-all=true), so this job runs and consistently times out: the inner
`go test -timeout 30m` cannot pull a 10 GB file from HuggingFace's throttled
Xet CDN within budget (curl --max-time 600 x5 retries overruns the deadline),
leaving an orphaned curl and a 30m panic. It has been red on every release
(v4.5.3/4/5).

Guard the job's `if` with `!startsWith(github.ref, 'refs/tags/')` so it no
longer runs on tag/release builds. It still runs on PRs and branch pushes that
touch vibevoice-cpp, so real regressions are caught off the release path. A
proper fix (a small ASR test GGUF) can re-enable it on tags later.

f0d0bff232 fix(llama-cpp): stop reinterpreting plain-string message content as JSON (#10524) (#10538)
The llama-cpp gRPC backend reconstructs OpenAI messages from proto for the
tokenizer-template path and blindly json::parse'd each message's content
string. LocalAI's Go layer always flattens content to a plain string, so a
user prompt that merely looks like JSON (e.g. mealie's ingredient array
["1/4 cup brown sugar", ...]) was reinterpreted as structured content parts and
rejected by oaicompat_chat_params_parse with "unsupported content[].type".

Normalize content per role instead: user/system/developer content is opaque
text and is never JSON-sniffed; assistant/tool content still collapses a literal
JSON null/object (tool-call bookkeeping) to a string, but a plain string is
never turned into an array/scalar. The array defense is role-independent, so the
role gate only governs the benign null/object case.

While here, extract the duplicated per-message reconstruction and the
pre-template content sanitization into shared, unit-tested helpers
(message_content.h) so the streaming (PredictStream) and non-streaming (Predict)
paths cannot drift. This removes ~490 lines of copy-pasted defensive code, the
dead tool-role parse branches, and the redundant Predict-only tool_calls branch,
while preserving the prior #7324 (null content -> "") and #7528 (tool array
content -> string) fixes.

Tests:
- backend/cpp/llama-cpp/message_content_test.cpp: standalone C++ unit tests for
  all three helpers (#10524, #7324, #7528, multimodal), discovered and run by
  `make test-backend-cpp` and a new generic tests-backend-cpp CI job. Also wired
  as an opt-in CMake/ctest target (-DLLAMA_GRPC_BUILD_TESTS=ON).
- core/schema/message_test.go: Go regression pinning that ToProto flattens a
  JSON-array-looking text part to the verbatim string.
- prepare.sh now copies message_content.h into the build tree.

- The bare local-ai darwin server binary is signed + notarized via

- All signing is gated on secrets being present, so forks/PRs/local builds
  stay unsigned and green (contrib/macos/sign-and-notarize.sh no-ops).

6afe127cd4 fix(backends): make the opus backend build and package on macOS/Darwin (#10523)
The opus Go backend (WebRTC audio codec) never built on macOS, so the
published master-metal-darwin-arm64-opus image shipped source only — no
opus binary and no libopusshim — because every step assumed Linux.

- Makefile: hardcoded libopusshim.so with no OS handling. Mirror
  sherpa-onnx: SHIM_EXT=so / dylib on Darwin and build
  libopusshim.$(SHIM_EXT). On Darwin link the shim with
  -undefined dynamic_lookup so it resolves opus_encoder_ctl from the
  already globally-loaded libopus (codec.go dlopens it RTLD_GLOBAL
  first) instead of baking an absolute Homebrew path into the dylib,
  keeping the packaged shim relocatable.
- run.sh: hardcoded LD_LIBRARY_PATH + libopusshim.so even on macOS. Add
  a Darwin branch exporting DYLD_LIBRARY_PATH and the .dylib shim, like
  sherpa-onnx/run.sh.
- package.sh: bundle libopusshim.$(SHIM_EXT) and libopus*.dylib (not
  just .so) into package/lib so the OCI image (which ships package/.)
  is self-contained on a runtime with no Homebrew; add a Darwin arch
  branch so it doesn't warn/skip.
- backend_build_darwin.yml: install + link opus and pkg-config via brew
  so the Makefile's `pkg-config opus` resolves on the macOS runner, and
  cache opus' Cellar dir.

Go code is unchanged; darwin build is validated in CI.

d388f874de feat(backends): darwin/Metal build for the privacy-filter backend (#10513)
* feat(backends): darwin/Metal build for the privacy-filter backend (timeboxed try)

The privacy-filter.cpp engine is already Metal-capable on Apple Silicon: it pulls
ggml and never forces GGML_METAL=OFF, and ggml defaults Metal ON on Apple, so a
plain Darwin build is Metal-enabled. grpc++/protobuf resolve from Homebrew via
find_package(... CONFIG). It just had no darwin build path - the existing
package.sh and run.sh are Linux-only and there was no make target / workflow step.

Adds the bespoke darwin path, modeled on the ds4 one:
- scripts/build/privacy-filter-darwin.sh: native make grpc-server, otool -L dylib
  bundling, create-oci-image (no Linux package.sh).
- Makefile: backends/privacy-filter-darwin target (+ .NOTPARALLEL).
- .github/workflows/backend_build_darwin.yml: gated build step for privacy-filter.
- scripts/changed-backends.js: inferBackendPathDarwin special-case -> backend/cpp.
- .github/backend-matrix.yml: includeDarwin entry (lang go, like ds4/llama-cpp).
- backend/index.yaml: metal: capability + metal-privacy-filter(-development) entries.
- backend/cpp/privacy-filter/run.sh: DYLD_LIBRARY_PATH branch on Darwin.

* fix(privacy-filter): macOS proto include + bundle ggml dylibs

Validated natively on an M4 (the build/package/load chain now works with Metal):

- CMakeLists.txt: hw_grpc_proto compiles the generated proto/grpc sources but
  only linked the binary dir, so on macOS it could not find protobuf's headers
  (runtime_version.h) - Homebrew puts them under /opt/homebrew, not /usr/include.
  Link protobuf::libprotobuf + gRPC::grpc++ so their include dirs propagate. No-op
  on Linux (apt headers are already on the default search path).
- privacy-filter-darwin.sh: bundle the ggml shared libs the binary @rpath-links
  (libggml{,-base,-cpu,-blas,-metal}); the otool -L walk only catches on-disk
  absolute deps and missed them. Resolved at runtime by run.sh's DYLD_LIBRARY_PATH.

M4 check: arm64 grpc-server links @rpath/libggml-metal.0.dylib; with the 15 ggml
dylibs + grpc/protobuf bundled, it loads clean (no dyld errors) and prints usage.

3a87d9e48f feat(vllm): macOS/Metal support via vllm-metal (MLX) (#10489)
* feat(vllm): macOS/Metal support via vllm-metal (MLX)

Add an additive Apple-Silicon path to the existing vllm Python backend so
vLLM runs on macOS via vllm-metal (github.com/vllm-project/vllm-metal).

Spike outcome (proven on a real M4 / macOS 26.5, Qwen3-0.6B):
- vllm-metal registers through vLLM's platform-plugin entry point
  (metal -> vllm_metal:register); MetalPlatform activates and runs on the
  GPU through MLX.
- LocalAI's backend.py is UNCHANGED: AsyncEngineArgs(...) ->
  AsyncLLMEngine.from_engine_args transparently resolves to vLLM 0.23's v1
  AsyncLLM MLX engine, and async generate produced correct output.
- backend.py is NOT touched: its only empty_cache() call is CUDA-only
  (guarded by torch.cuda.is_available()), so the benign shutdown-only
  "Allocator for mps is not a DeviceAllocator" noise comes from vLLM's
  internal EngineCore teardown, not from our code.

Changes (all gated behind a darwin condition; Linux/CUDA/ROCm/Intel paths
are byte-for-byte unchanged):
- install.sh: darwin branch forces PYTHON_VERSION=3.12 (vllm-metal
  requirement), creates/activates LocalAI's managed venv via ensureVenv,
  then reproduces vllm-metal's installer INTO that venv (build vLLM 0.23.0
  from the release source tarball against requirements/cpu.txt, then install
  the prebuilt vllm-metal wheel from its latest GitHub release), and runs
  runProtogen. installRequirements is skipped on darwin.
- backend-matrix.yml: add a vllm includeDarwin entry (mps, python).
- index.yaml: add metal capability + concrete metal-vllm /
  metal-vllm-development child entries mirroring the metal-kitten-tts
  template.

Version coupling: vllm-metal pins vLLM 0.23.0, equal to LocalAI's current
vllm pin. Bumping vllm must be coordinated with a supporting vllm-metal
release; documented in install.sh and requirements-cublas13-after.txt.

* chore(vllm): track the darwin vllm-metal pin via the autobumper

The Apple Silicon build pinned vLLM 0.23.0 as a hidden string in install.sh
while floating the vllm-metal wheel on releases/latest - the two could drift
apart silently. Make both a tracked, reproducible pair (VLLM_METAL_VERSION +
VLLM_VERSION), fetch the wheel by tag, and add .github/bump_vllm_metal.sh wired
into bump_deps.yaml. It tracks vllm-project/vllm-metal (not vllm/vllm latest),
reading the coupled vLLM source version from vllm-metal's own installer, and
opens a bump PR - mirroring the existing bump_vllm_wheel.sh for the cu130 wheel.

* chore(vllm): derive the darwin vLLM version, drop the second pin

Follow-up: VLLM_VERSION was still a hardcoded string duplicating what
VLLM_METAL_VERSION already determines. Derive it at install time from
vllm-metal's own installer (vllm_v=) at the pinned tag - one source of truth,
no second value to drift. The bumper now touches only VLLM_METAL_VERSION;
the derivation is immutable per tag, so builds stay reproducible.

* fix(vllm): fetch the vllm-metal wheel without the GitHub API

The darwin build resolved the wheel URL via api.github.com, whose
unauthenticated rate limit (60/hr per IP) 403s on shared macOS runners
(observed after the 9-min vLLM source build). Construct the release-asset
download URL deterministically from the pinned tag and the cp312/arm64 wheel
name instead - no API call, no rate limit. Verified the URL resolves (200).

* fix(vllm): fail Score cleanly when the engine returns no prompt_logprobs

Audit of the Score path against vllm-metal (MLX on macOS): the engine accepts
SamplingParams(prompt_logprobs=1) but returns an all-None prompt_logprobs list
rather than computing it, so scoring is not supported there. The old guard
treated the truthy [None] list as valid and silently scored every candidate as
0. Detect the all-None case and return UNIMPLEMENTED instead. No-op on
Linux/CUDA, which populate real entries.

63bcbf6c12 fix(pii): post-merge review fixes + live NER e2e for the privacy-filter tier (#10401)
* fix(pii): post-merge review fixes + live NER e2e for the privacy-filter tier

Follow-up to the NER tier engine (#10360), already on master. This carries
only the incremental review fixes and tests that postdate that merge — the
feature itself is not re-introduced.

Review fixes:
- openai_completion.go: remove the dead `elem >= 0` conjunct in applyAnyText
  (the `elem < 0` guard above already returns).
- application.go: collapse ResolvePIIPolicy's inline re-implementation of
  PIIIsEnabled to a single cfg.PIIIsEnabled() call (sole source of the
  "explicit pii.enabled wins, else cloud-proxy default" rule) and return true
  past the !enabled guard where it is provable.
- pattern.go: hoist the triple `appConfig != nil && EnableTracing` check in
  patternDetector.Detect into one local.
- grammar.go: MaxQuantifier was 4096, but Go's regexp/syntax rejects repeat
  bounds above 1000 at Parse time, so walk()'s {n,m} guard could never fire —
  dead code shadowed by the parser. Lower it to 512 so a bound in (512,1000]
  is rejected here with an actionable error; >1000 still fails closed via
  Parse. Specs pin the relationship so the guard can't silently revert.
- PatternListEditor.jsx: clamp a directly-typed negative min_len to >=0 and
  force the DOM value back when clamping (min={0} only constrained the spinner,
  so a negative reached saved config and silently disabled the length filter).

Tests:
- piipattern_test.go: MaxQuantifier guard specs (must stay live, not dead).
- model-config.spec.js: assert the min_len clamp, and that entity_actions
  collapses a duplicate group to a single row (map semantics; regression guard
  against emitting an array that drops a row on save).
- tests/e2e-backends: token_classify capability driving the TokenClassify gRPC
  RPC against the backend image, asserting byte-correct, UTF-8 rune-aligned
  spans (entity.Text == text[start:end]) at threshold 0. Verified on CPU via
  `make test-extra-backend-privacy-filter` (3/3 specs).
- Makefile: test-extra-backend-privacy-filter wrapper.
- tests/e2e: e2e_pii_ner_test.go drives /api/pii/analyze + /api/pii/redact
  (mask + block) through the full HTTP -> detector -> redactor path; gated on
  PII_NER_MODEL_GGUF so the default suite is unaffected.
- .github/workflows/tests-pii-ner-e2e.yml: path-filtered / nightly CI job
  running the container harness on CPU.

GGUF conversions of OpenMed/privacy-filter-nemotron — a fine-grained English

openai/privacy-filter on NVIDIA's Nemotron-PII dataset. Sibling to the existing
privacy-filter-multilingual entry, trading language breadth for category depth.

- privacy-filter-nemotron: F16 reference artifact (~2.8 GB).
- privacy-filter-nemotron-q8: Q8_0 quant (~1.64 GB) for RAM-constrained / edge
  use; description notes the size/speed tradeoff and to validate on your own
  data (a single dropped span is a PII leak).

Both run on the privacy-filter backend with known_usecases [token_classify] and
a default mask policy (min_score 0.5); operators add per-category entity_actions
as needed. sha256s taken from the HF repo's LFS object ids.

Wires ced.cpp (CED, 527-class AudioSet sound-event tagger; baby cry,

- DESIGN.md: REST /v1/audio/classification wiring (handler/route/capability
  registration checklist), gallery/index + CI registration, and a scoping
  note for the realtime/websocket live-recognition path (sliding-window
  classify over the existing ws transport + voicegate; the ced C-API
  per-PCM entry point is already window-friendly).

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Reconciled against master's independent evolution:

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

* feat(backend): add depth-anything (Depth Anything 3) C++/ggml backend + gallery

Mirrors the locate-anything-cpp backend to register a new depth-anything
backend that wraps the Depth Anything 3 ggml port (depth-anything.cpp) via
purego (cgo-less, no Python at inference).

- backend/go/depth-anything-cpp/: gRPC backend (Load + Predict + GenerateImage),
  purego binding to the da_capi_* C ABI, CMake/Makefile/run/package/test scripts
  building depth-anything.cpp's DA_SHARED static .so per CPU variant.
- backend/index.yaml: depth-anything backend meta + all hardware-variant
  capability entries (cpu/cuda12/cuda13/intel-sycl-f32+f16/vulkan/nvidia-l4t).
- gallery/index.yaml: 8 Depth Anything 3 GGUF models (base q4_k/q8_0/f16/f32,
  small, large, giant, mono-large).
- .github/backend-matrix.yml: one build entry per hardware variant.

* fix(depth): wire depth-anything-cpp into build, CI bump, and importer

The backend dir, gallery index, and CI build-matrix were present but the
backend was never wired into the integration points that adding-backends.md
requires:

- root Makefile: add to .NOTPARALLEL, the test-extra chain, a BACKEND_*
  definition, the docker-build target eval, and docker-build-backends
  (mirrors parakeet-cpp; the backend's own Makefile already documented that
  its `test` target is driven by test-extra).
- bump_deps.yaml: register the DEPTHANYTHING_VERSION pin so the daily
  auto-bump bot tracks mudler/depth-anything.cpp master (it cannot see an
  unregistered Makefile pin).
- import form: add a preference-only KnownBackend entry so depth-anything is
  selectable at /import-model (mirrors sam3-cpp; no reliable GGUF auto-detect
  signal, so pref-only per the doc's default).

changed-backends.js needs no entry: the generic golang suffix branch already
resolves backend/go/depth-anything-cpp/.

* feat(depth): auto-detect importer for depth-anything GGUFs

Replace the preference-only entry with a real auto-detect importer
(mirrors parakeet-cpp / locate-anything):

- DepthAnythingImporter matches a .gguf whose name carries a
  depth-anything token (depth-anything-<size>-<quant>.gguf), so
  /import-model recognises mudler/depth-anything.cpp-gguf repos and direct
  GGUF URLs without an explicit backend preference. preferences.backend=
  "depth-anything" still forces it.
- Registered before LlamaCPPImporter so its GGUF bundles aren't claimed by
  the generic .gguf importer; the narrow name match means it cannot claim
  arbitrary llama GGUFs or the upstream safetensors PyTorch repos.
- Multi-quant repos pick the smallest quant by default (q4_k -> ... -> f32,
  depth stays >0.998 corr even at q4_k); quantizations preference overrides.
- Drops the now-redundant knownPrefOnlyBackends entry (importer-backed
  backends are not listed there, matching parakeet-cpp).
- Table-driven Ginkgo test covers detection, negative cases (llama GGUF,
  upstream safetensors), default/override/fallback quant pick, and direct
  URL import. 10/10 specs pass.

* fix(depth): resolve gosec findings in the backend wrapper

The code-scanning gate flagged three new failure-level alerts in
godepthanythingcpp.go (gosec runs with -no-fail; GitHub gates on new alerts):

- G301: export dirs were created with 0o755. Tighten to 0o750 (no world
  access needed for backend-written export output).
- G304: writeDepthPNG creates req.GetDst(). That path is chosen by the
  LocalAI core as the intended output destination (same pattern every
  image backend uses), not attacker input, so annotate with #nosec G304
  and document why.

The remaining G103 "audit unsafe" notes on the unsafe.Slice C-buffer copies
are warning-level (the same purego interop whisper/parakeet use) and do not
gate the check, per the supertonic exclusion precedent in secscan.yaml.

hw_grpc_proto links neither protobuf::libprotobuf nor gRPC::grpc++, so

085fc53bbc fix(router): production-ready request router + auto-size batch for embedding/rerank (#10104)
* fix(router): score classifier production-readiness

Conversation trimming runs through the classifier model's chat template
and trims by exact token count, sized to the model's n_batch which is
now scaled to context so long probes can't crash the backend. Missing
chat_message templates are a hard error at router build time. Router-
facing factories (Embedder/Scorer/Reranker/TokenCounter) re-resolve
ModelConfig per call so a model installed post-startup doesn't bind a
stub Backend="" config and silently fall into the loader's auto-
iterate path.

New 'vector_store' backend trace recorded inside localVectorStore on
every Search/Insert — including the backend-load-failure path that
previously vanished into an xlog.Warn — with outcome tagging
(hit/miss/empty_store/backend_load_error/find_error/insert_error/ok).
Companion cleanup drops misleading similarity:0 and input_tokens_count:0
from non-hit and text-mode traces.

Gallery local-store-development aliases to 'local-store' so the master
image satisfies pkg/model.LocalStoreBackend lookups from the embedding
cache.

Misc: llama-cpp TokenizeString reads the correct 'prompt' JSON key
(the original bug); ModelTokenize nil-guard; non-fatal mitm proxy
startup; PII 'route_local' renamed to 'allow' with docs/UI in sync;
model-editor footer no longer eats the edit area on small screens;
several config-editor template/dropdown/section fixes.

Tests: e2e router specs (casual/code-hint + long-conversation trim),
vector_store trace specs, lazy-factory specs, gallery dev-alias
resolution, Playwright trace badge + scroll regression.

* feat(backend): auto-size batch to context for embedding and rerank models

Embedding and rerank models pool over the whole input in a single physical batch (n_ubatch). With batch left at the 512 default, the backend rejects longer inputs with "input is too large to process", silently capping a large-context embedder (e.g. 8k/32k) at 512 tokens. Size n_batch to the context for these single-pass usecases, mirroring the existing FLAG_SCORE behaviour; an explicit batch: still wins.

Extracts EffectiveContextSize/EffectiveBatchSize from grpcModelOpts so the effective decode window has one home for other callers to reuse.

Adds an e2e-aio regression test that embeds a >512-token input. The AIO embedding model is switched to nomic-embed-text-v1.5 (2048 context) because the previous granite model was capped at 512 tokens and could not exercise the larger batch.

* fix(gallery): raise arch-router scoring output cap via parallel:64

Scoring decodes the whole prompt+candidate in a single llama_decode and
reads one logit row per candidate token. The vendored llama.cpp server
caps causal output rows at n_parallel, so the default of 1 aborts with
GGML_ASSERT(n_outputs_max <= cparams.n_outputs_max) on multi-token route
labels. Set options: [parallel:64] on both arch-router quant entries to
lift the cap; kv_unified (the grpc-server default) keeps the full context
per sequence, so this does not split the KV cache.

* feat(crispasr): switch shim to crispasr_session_* multi-architecture API

The shim used whisper_full(), which in CrispASR is the whisper-only path:
libcrispasr only transcribes Whisper GGUFs through it. Multi-architecture
transcription (Parakeet, Voxtral, Qwen3-ASR, Canary, Granite, FunASR,
Paraformer, SenseVoice, ...) goes through the crispasr_session_* C-ABI,
which auto-detects the architecture from the GGUF and dispatches to the
matching backend.

Rewrite the C shim around crispasr_session_open / _transcribe_lang /
_result_* and add get_backend() so the selected backend is logged.
load_model now takes a threads param (session_open binds n_threads at
open). The session result is segment+word based with no token IDs and no
per-decode callback, so drop n_tokens / get_token_id /
get_segment_speaker_turn_next / set_new_segment_callback. set_abort is
kept for API parity but is best-effort: the session transcribe is blocking
with no abort hook.

Update the purego bindings and gocrispasr.go to match: tokens are left
empty, speaker-turn handling is removed, and AudioTranscriptionStream
emits one delta per non-empty segment after the blocking decode returns
(no progressive streaming via the session API), preserving the
concat(deltas) == final.Text invariant.

crispasr_session_set_translate is exported by libcrispasr but not declared
in crispasr.h, so it is forward-declared in the shim alongside the
open/transcribe/result functions.

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

* build(crispasr): link full CrispASR backend set for multi-arch support

The shim's crispasr_session_* dispatch calls into the per-architecture
backend libs (parakeet, voxtral, qwen3_asr, canary, funasr, paraformer,
sensevoice, ...), which CrispASR builds as static archives. Linking only
crispasr + ggml dead-stripped every backend object from the final module
(nm backend-symbol count: 0), leaving a whisper-only .so.

Link the same backend set as crispasr-cli so the static archives are
pulled in. After this the module carries the backend symbols (nm count
407, .so grows from ~2.1MB to ~6.7MB) and the session API can dispatch to
every compiled-in architecture.

Also rewrite ${CMAKE_SOURCE_DIR}/examples/talk-llama to
${PROJECT_SOURCE_DIR}/... in the vendored src/CMakeLists.txt: CrispASR
locates its vendored llama.cpp via ${CMAKE_SOURCE_DIR}, which is wrong when
CrispASR is add_subdirectory'd (CMAKE_SOURCE_DIR points at this backend
dir, not the CrispASR root). PROJECT_SOURCE_DIR is correct both standalone
and as a subproject; the sed is idempotent.

* test(crispasr): adapt suite to session API (blocking, no decode callback)

Register the new symbol set (drop the removed token/speaker/callback funcs,
add get_backend; load_model now takes 2 args). The session transcribe is
blocking with no abort hook, so a mid-decode cancel can't interrupt it:
change the cancellation spec to cancel the context before the call and
assert codes.Canceled from the pre-call ctx.Err() check, dropping the
<5s mid-decode timing assertion. The streaming spec still holds with
per-segment post-decode emission (>=2 deltas, concat(deltas) == final.Text).

* feat(gallery): add CrispASR ASR model entries (-crispasr)

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

* fix(gallery): keep only session-auto-detectable CrispASR ASR models

The crispasr backend loads models via crispasr_session_open, which
auto-detects the backend from the GGUF general.architecture using
crispasr_detect_backend_from_gguf. Architectures not in that detect
map cannot be opened, so those gallery entries fail to load.

Removed entries whose architecture is not wired into CrispASR
v0.6.11's session auto-detect router (they can be re-added when
upstream maps them):

- Not in the detect map: data2vec, firered-asr, funasr,
  fun-asr-mlt-nano, glm-asr, hubert, kyutai-stt, mega-asr, mimo-asr,
  moonshine{,-de,-streaming,-tiny-de}, omniasr{,-llm,-llm-1b},
  paraformer, sensevoice.
- Pending verification (filename-heuristic routed, not arch-detected):
  parakeet-ctc-0.6b, parakeet-ctc-1.1b. Their GGUFs are routed to the
  fastconformer-ctc backend by a filename heuristic in the model
  registry, which implies general.architecture is not a mapped string.

Kept the parakeet rnnt/tdt_ctc variants: convert-parakeet-to-gguf.py
writes general.architecture="parakeet" unconditionally and encodes the
rnnt/ctc distinction in metadata fields, so they session-auto-detect.

* feat(crispasr): TTS synthesis via crispasr_session_synthesize (24kHz)

Add tts_synthesize/tts_free/tts_set_voice to the C-ABI shim. They reuse
the already-open g_session (crispasr_session_open auto-detects a TTS
model) and dispatch to the upstream synthesis call, which returns
malloc'd 24 kHz mono float PCM. Orpheus needs a SNAC codec path that we
do not set, so it returns NULL here and surfaces as an error Go-side.

* feat(crispasr): implement TTS/TTSStream gRPC methods

Bind the new shim functions via purego and implement TTS, TTSStream and
a writeWAV24k helper. synthesize copies the C-owned PCM out before
freeing it; TTS writes a 24 kHz mono 16-bit WAV to req.Dst via
go-audio/wav. CrispASR has no progressive synth, so TTSStream
synthesizes fully, encodes to WAV, and emits the bytes as a single
chunk; it owns the results-channel close (the gRPC server wrapper ranges
until close), mirroring vibevoice-cpp's TTSStream.

* feat(crispasr): backend: and codec: model options (explicit arch + companion files)

Add two model-config options to the CrispASR backend via opts.Options:

- backend:<name> selects an explicit CrispASR backend (bypassing
  auto-detect) by routing load_model through
  crispasr_session_open_explicit, unlocking architectures the
  detector won't pick on its own (qwen3, cohere, granite, voxtral,
  moonshine, mimo-asr, orpheus, kokoro, chatterbox, etc.).
- codec:<path> loads a companion file (qwen3-tts codec, orpheus SNAC,
  chatterbox s3gen, or mimo-asr tokenizer) via the universal
  crispasr_session_set_codec_path setter after the session opens. A
  relative path resolves against the model directory. rc==0 means
  success or not-applicable; only a negative rc is fatal.

The C shim load_model gains a backend_name argument and a new
set_codec_path entry point; the Go bridge parses the prefix:value
options and registers the new symbol. The vad_only path is unchanged.

* fix(gallery): drop voice-requiring TTS entries (keep vibevoice-tts)

Real e2e showed qwen3-tts/orpheus/chatterbox don't synthesize through the
current shim: the codec: companion loads fine, but these engines additionally
need a voice pack / voice prompt / reference clip (qwen3-tts base errors
'no voice'; chatterbox is zero-shot cloning; orpheus uses named voices) that
the backend doesn't wire. (qwen3-tts also can't auto-detect: its GGUF arch is
'qwen3tts', unmapped by the detector — would need backend:qwen3-tts.) Removed
to avoid shipping non-working gallery entries; vibevoice-tts (built-in voice,
e2e-verified) remains the working TTS. Voice-pack wiring is a follow-up.

4912c9b73a feat(parakeet-cpp): add NVIDIA NeMo Parakeet ASR backend (parakeet.cpp) (#10084)
* feat(parakeet-cpp): L0 backend scaffold, LoadModel + AudioTranscription (text)

Add a Go gRPC backend that bridges LocalAI to parakeet.cpp via the flat
C-API (parakeet_capi.h), loaded with purego (cgo-less, mirrors the
whisper / vibevoice-cpp backends).

L0 scope:
- main.go: dlopen libparakeet.so (override via PARAKEET_LIBRARY), register
  the C-API entry points, start the gRPC server.
- goparakeetcpp.go: Load (parakeet_capi_load), AudioTranscription
  (parakeet_capi_transcribe_path, decoder=0 = per-arch default head),
  Free, serialized through base.SingleThread since the C engine is a
  thread-unsafe singleton. char* returns are bound as uintptr so the
  malloc'd buffer is freed via parakeet_capi_free_string after copy.
- AudioTranscriptionStream returns a clear "not implemented in L0" error
  (closes the channel so the server doesn't hang), wired in L2.
- Makefile: clone-at-pin + cmake (PARAKEET_VERSION for bump_deps.sh),
  with a local-symlink dev shortcut; run.sh / package.sh mirror whisper.
- Test auto-skips without PARAKEET_BACKEND_TEST_MODEL/_WAV fixtures.

Builds clean (CGO_ENABLED=0), gofmt clean, test passes. The single
unsafeptr vet note in goStringFromCPtr is documented and matches the
whisper backend's tolerated pattern.

Word/segment timestamps (L1) and cache-aware streaming (L2) follow.

* feat(parakeet-cpp): L1 word/segment timestamps via transcribe_path_json

AudioTranscription now calls parakeet_capi_transcribe_path_json and shapes
the per-word / per-token timestamps into the TranscriptResult:

- Bind parakeet_capi_transcribe_path_json (purego, char* as uintptr like
  the other returns) and register it in main.go + the test loader.
- Parse the JSON document ({"text","words":[{w,start,end,conf}],
  "tokens":[{id,t,conf}]}) into typed structs.
- Synthesise a single whole-clip segment (parakeet emits no native segment
  boundaries) spanning the first word start to the last word end; token ids
  populate Segment.Tokens.
- Attach word-level timings only when timestamp_granularities=["word"],
  matching the OpenAI API (segment-level default). secondsToNanos mirrors
  the whisper backend's nanosecond convention.

Verified end-to-end against tdt_ctc-110m (f16): both the default and
word-granularity specs pass; builds clean, gofmt clean, vet shows only the
one documented unsafeptr note shared with the whisper backend.

Cache-aware streaming (L2) follows.

* feat(parakeet-cpp): L2 cache-aware streaming with EOU segmentation

Wire AudioTranscriptionStream to the streaming RNN-T C-API:

- Bind parakeet_capi_stream_{begin,feed,finalize,free}; feed takes 16 kHz
  mono float PCM ([]float32 via purego) and writes *eou_out on <EOU>/<EOB>.
- Decode opts.Dst to 16 kHz mono PCM (utils.AudioToWav + go-audio, same as
  the whisper backend), feed it in 1 s chunks, and emit each newly-finalized
  text run as a TranscriptStreamResponse delta.
- <EOU>/<EOB> events close the current segment; a closing FinalResult carries
  the full transcript plus the per-utterance segments (with a whole-clip
  fallback segment when no EOU fired).
- stream_begin returns 0 for non-streaming models, surfaced as a clear
  error instead of an empty stream. Honours context cancellation between
  chunks. Frees every malloc'd delta and the session.

Verified end-to-end against realtime_eou_120m-v1 (f16): the streamed
transcript matches the offline 110m reference word-for-word, deltas
reconstruct the final text, and the spec passes alongside the offline
specs. Builds clean, gofmt clean, vet shows only the shared documented
unsafeptr note.

* feat(parakeet-cpp): L3 register backend in build/CI/gallery (whisper parity)

Wire the new Go gRPC parakeet-cpp backend (parakeet.cpp ggml port of NVIDIA
NeMo Parakeet ASR) into LocalAI's build/CI/gallery surfaces, matching the
existing ggml whisper Go backend 1:1.

- .github/backend-matrix.yml: add 11 linux entries + 1 darwin entry mirroring
  every whisper build (cpu amd64/arm64, intel sycl f32/f16, vulkan amd64/arm64,
  nvidia cuda-12, nvidia cuda-13, nvidia-l4t-arm64, nvidia-l4t-cuda-13-arm64,
  rocm hipblas, metal-darwin-arm64), all on ./backend/Dockerfile.golang with
  backend: "parakeet-cpp" and -*-parakeet-cpp tag-suffixes.
- scripts/changed-backends.js: explicit inferBackendPath branch resolving
  parakeet-cpp to backend/go/parakeet-cpp/ before the generic golang branch.
- .github/workflows/bump_deps.yaml: track the PARAKEET_VERSION pin in
  backend/go/parakeet-cpp/Makefile (repo mudler/parakeet.cpp, branch master).
- backend/index.yaml: add &parakeetcpp meta + latest/development image entries
  for every matrix tag-suffix.
- Makefile: add backends/parakeet-cpp to .NOTPARALLEL, BACKEND_PARAKEET_CPP
  definition, docker-build target eval, and test-extra-backend-parakeet-cpp-
  transcription target (mirrors test-extra-backend-whisper-transcription).

* feat(parakeet-cpp): L4 gallery importer for parakeet GGUFs

Add ParakeetCppImporter so parakeet.cpp GGUFs auto-detect on /import-model
and route to the parakeet-cpp backend (it also surfaces in /backends/known,
which drives the import dropdown).

- Match is narrow: a .gguf whose name carries a parakeet architecture token
  (<arch>-<size>-<quant>.gguf, e.g. tdt_ctc-110m-f16.gguf, rnnt-0.6b-q4_k.gguf,
  realtime_eou_120m-v1-q8_0.gguf), a direct URL to one, or
  preferences.backend="parakeet-cpp". It deliberately does NOT claim arbitrary
  llama-style GGUFs, nor the upstream nvidia/parakeet-* NeMo repos (.nemo, not
  runnable here).
- Registered in the ASR batch BEFORE LlamaCPPImporter so its GGUFs aren't
  swallowed by the generic .gguf importer.
- Import nests files under parakeet-cpp/models/<name>/, defaults to the
  smallest quant (q4_k, near-lossless on parakeet) with a size-ladder
  fallback, and honours preferences.quantizations / name / description.

Tested with synthetic HF details (no network): metadata, positive matches
(HF repo, direct URL, preference), narrowness negatives (llama GGUF, NeMo
repo), and import (default quant, override, direct URL), 9 specs pass,
build/vet/gofmt clean.

* docs(parakeet-cpp): document the parakeet-cpp transcription backend

Add parakeet-cpp to the audio-to-text backend list and a dedicated usage
section: direct GGUF import (auto-detects to the backend), model YAML,
word-level timestamps via timestamp_granularities[]=word, and cache-aware
streaming with the realtime_eou model. Points at the mudler/parakeet-cpp-gguf
collection repo.

* ci(parakeet-cpp): wire transcription gRPC e2e test into test-extra

The L3 commit added the test-extra-backend-parakeet-cpp-transcription
Makefile target but never invoked it in CI. Mirror the whisper job:

- Add a parakeet-cpp output to detect-changes (emitted by
  changed-backends.js from the matrix entry).
- Add tests-parakeet-cpp-grpc-transcription, gated on the parakeet-cpp
  path filter / run-all, building the backend image and running the
  transcription e2e against tdt_ctc-110m + the JFK clip.

* style(parakeet-cpp): drop em dashes from comments and docs

Replace em dashes with plain punctuation in the backend comments, the
importer, package.sh, and the audio-to-text docs section (and use "and"
instead of the multiplication sign). No behaviour change.

* feat(gallery): add parakeet-cpp f16 models to the model gallery

Add the 10 NVIDIA Parakeet models (f16, the recommended quality/speed
default) as gallery entries that install on the parakeet-cpp backend from
mudler/parakeet-cpp-gguf: tdt_ctc-110m/1.1b, tdt-0.6b-v2/v3, tdt-1.1b,
ctc-0.6b/1.1b, rnnt-0.6b/1.1b, and the cache-aware streaming
realtime_eou_120m-v1. Each pins the file sha256 and routes transcript
usecases to the backend.

* fix(parakeet-cpp): satisfy govet lint + bump PARAKEET_VERSION

- goparakeetcpp.go: //nolint:govet on the C-owned-pointer unsafe.Pointer
  conversion (golangci-lint reports new-only issues, so unlike the whisper
  backend's identical line this one is flagged).
- Makefile: bump PARAKEET_VERSION to the current parakeet.cpp master commit
  (the previous pin's commit no longer exists after upstream history was
  squashed), so the backend image clone/build resolves again.

* fix(parakeet-cpp): pin PARAKEET_VERSION to a tag-stable commit

The previous SHA pin was orphaned when parakeet.cpp's single-commit master
was amended/force-pushed, so the backend image clone (git fetch <sha>) failed
across every build variant. Repoint to 845c29e, which upstream now keeps
permanently fetchable via the `localai-backend-pin` tag, so future upstream
amends no longer break the backend build.

* fix(parakeet-cpp): init the ggml submodule in the backend image clone

The backend Dockerfile clones parakeet.cpp at PARAKEET_VERSION with a shallow
fetch + checkout but never initialised submodules, so third_party/ggml was
empty and the parakeet.cpp cmake build failed at
`add_subdirectory(third_party/ggml)` (CMakeLists.txt:53) on every build
variant. Add `git submodule update --init --recursive --depth 1
--single-branch` after checkout, mirroring the whisper backend. Verified
locally: clone + submodule + cmake configure now succeeds.

* fix(parakeet-cpp): statically link ggml into libparakeet.so

The shared libparakeet.so linked ggml's shared libs (libggml*.so), but the
package only ships libparakeet.so, so at runtime dlopen failed with
"libggml.so.0: cannot open shared object file" (the e2e transcription test
panicked on load). Build ggml static + PIC (BUILD_SHARED_LIBS=OFF,
CMAKE_POSITION_INDEPENDENT_CODE=ON) so libparakeet.so embeds ggml and depends
only on system libs already present in the runtime image. Verified locally:
ldd shows no libggml dependency.

* fix(parakeet-cpp): non-streaming fallback in AudioTranscriptionStream

The e2e streaming test ran AudioTranscriptionStream against tdt_ctc-110m
(not a cache-aware streaming model), so stream_begin returned 0 and the call
errored. Per LocalAI's streaming contract (and the whisper backend), a
non-streaming model should fall back to a single offline transcription
emitted as one delta plus a closing FinalResult. Do that instead of erroring,
so the streaming endpoint works for every parakeet model. Verified locally:
the streaming spec passes against the non-streaming 110m model via fallback.
