fix(agents): make React agent chat timestamps format-agnostic
The agent SSE bridge emits the json_message timestamp in three different
encodings depending on deploy mode: an RFC3339 string (standalone agent
pool), Unix milliseconds (local dispatcher), and Unix nanoseconds (the
older NATS path). The React AgentChat handler passed data.timestamp
straight through, so the standalone string and any numeric value outside
the millisecond range rendered as "Invalid Timestamp" or a constant
epoch-ish time.
Add a small pure helper, normalizeTimestampMs, that accepts an RFC3339
string or a numeric epoch in s/ms/us/ns and returns JS milliseconds,
falling back to Date.now() on null/empty/unparseable input. Use it in
the json_message handler so the rendered time is correct regardless of
which backend path produced it.

Two small visual fixes in the React UI:
- Talk page pipeline summary: the four-column grid used
`repeat(4, 1fr)`, which resolves to `minmax(auto, 1fr)` so each track
refuses to shrink below the min-content width of its `nowrap` model
name. Long names (e.g. a verbose GGUF LLM id) blew the grid out past
the container despite the per-cell ellipsis styling. Switching to
`minmax(0, 1fr)` lets the tracks shrink and the ellipsis take effect.
- Sidebar user avatar: the desktop collapsed look centers the avatar via
`.sidebar.collapsed .sidebar-user{-link}` rules, but the tablet
icon-rail (640-1023px) collapses visually through `.sidebar:not(.open)`
without necessarily carrying the `.collapsed` class, so the avatar kept
its left-aligned negative margins and looked misaligned. Mirror the
centering rules under `.sidebar:not(.open)`.

The gallery has metal-ds4 / metal-ds4-development entries, and the build
recipe exists (make backends/ds4-darwin, special-cased in
backend_build_darwin.yml), but ds4 was never listed in the darwin matrix,
so no metal-darwin-arm64-ds4 image was ever published and the entries
dangled.
- Add ds4 to the darwin matrix (includeDarwin), mirroring the llama-cpp
form (the reusable workflow builds it via 'make backends/ds4-darwin').
- Fix inferBackendPathDarwin in scripts/changed-backends.js to map ds4 to
backend/cpp/ds4/ (like llama-cpp): ds4 is C++ but the matrix entry carries
lang=go, so without this its darwin build would only ever run on a release
(FORCE_ALL), never incrementally when backend/cpp/ds4 changes.
sherpa-onnx and speaker-recognition are already in the darwin matrix on
master and are not changed here.

fix(gallery): correct meta-backend definitions in backend/index.yaml
Backends that ship per-platform images must be meta backends (a capabilities
map and NO uri) so the right variant is auto-selected per platform - mirroring
llama-cpp/whisper. Several entries were misdefined; fixed here:
- Concrete base + metal sibling (could not select the Apple Silicon variant):
silero-vad, piper, kitten-tts, local-store (+ their -development). Converted
each anchor to a meta and added the cpu-<name> concrete.
- mlx family (mlx, mlx-vlm, mlx-audio, mlx-distributed + -development): anchor
had both a uri AND a capabilities map, so IsMeta() was false and the map was
ignored (always resolved to the metal-darwin image); the metal-<name> target
did not exist. Removed the uri and added the missing metal-<name> concretes.
- Dangling capability targets: diffusers/kokoro nvidia-l4t-cuda-12 repointed to
the existing nvidia-l4t-<name> concrete; coqui nvidia-cuda-13 key removed
(no cuda13-coqui image).
- locate-anything: the meta existed but its concrete entries were never added,
so it was un-installable on every platform. Added the full concrete set plus
the locate-anything-development meta, mirroring rfdetr-cpp. Image tags grounded
against the published quay.io tags.
- trl (cuda12/13): repointed the stale 'cublas-cuda12/13-trl' image tags to the
actually-published 'gpu-nvidia-cuda-12/13-trl' tags (fixes#9236).

fix(gallery): make opus a meta backend so the platform variant is auto-selected (#9813)
The realtime/WebRTC path loads the "opus" codec backend by name, but on
macOS arm64 only "metal-opus" is installable, so Load("opus") failed with
"opus backend not available".
The root cause: unlike llama-cpp and whisper, the opus entry was a concrete
CPU backend (it carried a uri and no capabilities map) rather than a meta
backend, so nothing mapped "opus" to the platform-appropriate variant.
Restructure opus to mirror llama-cpp/whisper: "opus" becomes a meta backend
with a capabilities map (default -> cpu-opus, metal -> metal-opus) and no
uri; the CPU image moves to a new "cpu-opus" concrete (and its dev variant
to "cpu-opus-development"). Installing "opus" now resolves to metal-opus on
Apple Silicon and cpu-opus elsewhere, and Load("opus") works on every
platform via the meta pointer - so the realtime endpoint needs no special
casing. This reverts the realtime_webrtc.go resolution helper from the
earlier approach in favor of the gallery-level fix.

fix(config): gate top_k=40 default on backend family (#6632)
SetDefaults injected top_k=40 (llama.cpp's sampling default) for every
model config regardless of backend. That value is wrong for backends
whose native default differs: mlx_lm's intended default is top_k=0
(disabled) and mlx does not remap 0->40, so a client that omits top_k
silently got 40 shipped to mlx, changing sampling. The mlx backend's own
getattr(request,'TopK',0) fallback is dead because proto3 int32 is always
present.
Gate the injection on backend family via UsesLlamaSamplerDefaults: keep
top_k=40 for the llama.cpp family and for the empty/auto backend (the GGUF
auto-detect path resolves to llama.cpp, so existing behavior is preserved),
but leave TopK nil for the known non-llama backends (mlx, mlx-vlm,
mlx-distributed). gRPCPredictOpts now sends 0 when TopK is nil, which is
the value mlx actually wants.
Only TopK is gated - the confirmed bug. The sibling sampler defaults
(top_p, temperature, min_p) are left global to avoid widening scope and
introducing nil-deref risk; revisit per-backend if needed.

against an empty model and the backend RPC failed with "unimplemented"

silently stopped whenever a language was selected.

Agent chat replies rendered a broken timestamp in the web UI
("Invalid Timestamp" / "12:00 AM", identical for every reply) because
the SSE timestamp unit was inconsistent across producers.
EventBridge.PublishEvent emitted Unix nanoseconds while the local
dispatcher (dispatcher.go) already emitted Unix milliseconds, and the
React UI fed the value straight into `new Date(ts)` after dividing by
1e6. Nanoseconds also overflow JS's safe-integer range (~1.7e18).
Standardize on Unix milliseconds: switch PublishEvent to UnixMilli and
drop the /1e6 conversion in AgentChat.jsx so both SSE paths agree and
match the React UI's expectation. Add a regression test asserting the
published timestamp is in milliseconds.
* fix(darwin): never package a go backend build tree as a working image
The darwin/arm64 vibevoice-cpp image shipped the source tree with a
half-built CMake directory (build-libgovibevoicecpp-fallback.so/) and no
backend binary, so the backend could never start: run.sh exec'd a
vibevoice-cpp binary that was not in the package and LocalAI timed out
waiting for the gRPC service.
Two durable, backend-agnostic defenses:
- backend/go/vibevoice-cpp/Makefile: mirror whisper's cleanup discipline so a
partial CMake tree cannot survive into packaging. Run `make purge` before
each variant build and `rm -rfv build*` after. The old recipe only removed
its build dir after a successful `mv`, so a failed build left the half-built
tree behind.
- scripts/build/golang-darwin.sh: before creating the OCI image, remove any
stray build-* directory and assert that the binary run.sh launches actually
exists. A build that produced no binary now fails the job loudly instead of
publishing a source tree as a working backend. The binary name is derived
from run.sh's `exec $CURDIR/<binary>` line (parakeet-cpp launches
parakeet-cpp-grpc, so it is not always ${BACKEND}) with a ${BACKEND}
fallback.
The underlying native build failure that left vibevoice-cpp half-built still
needs to be reproduced and fixed on Apple Silicon; this change ensures such a
failure can never again be published as a working image.

* fix(vibevoice-cpp): build libvibevoice.a on darwin (link target, not path)
The darwin build failed with:
No rule to make target 'vibevoice/libvibevoice.a', needed by
'libgovibevoicecpp.so'. Stop.
The upstream vibevoice project is added with add_subdirectory(... EXCLUDE_FROM_ALL),
so its `vibevoice` static-library target is only built when something links it
as a target. The Apple branch linked only `$<TARGET_FILE:vibevoice>` - a bare
archive path with no target reference - so CMake never emitted a rule to build
libvibevoice.a, while the Linux branch worked because it passes the `vibevoice`
target name inside the --whole-archive flags.
Link the `vibevoice` target on Apple (establishing the build dependency) and
apply -force_load as a separate link option to keep whole-archive semantics so
purego can dlsym the vv_capi_* symbols.

Vision-language checkpoints such as mlx-community/gemma-4-E4B-it-qat-4bit
declare the "image-text-to-text" pipeline tag on HuggingFace. The mlx
importer hardcoded backend "mlx" for every mlx-community model, so these
VLMs were served by the text-only mlx-lm backend whose tokenizer does not
carry the processor chat template. The template was never applied and the
model produced degenerate, looping output that echoed the prompt.
Detect the "image-text-to-text" pipeline tag in the importer and route those
models to mlx-vlm, which applies the processor-aware chat template. An
explicit backend preference still wins.
As a defensive backstop, the mlx backend now warns loudly when the loaded
model has no chat template, so a misrouted VLM surfaces the problem instead
of silently looping.

CrispASR's piper backend phonemizes non-English text via espeak-ng (dlopen,

latter two).
- package.sh: copy libespeak-ng.so.1, libpcaudio.so.0, libsonic.so.0 into

- run.sh: export CRISPASR_ESPEAK_DATA_PATH so the bundled data is found.

CrispASR's piper backend returns PCM at the voice's native rate (from the GGUF
piper.sample_rate key: 16 kHz for x_low/low, 22.05 kHz for medium/high) and does
not resample, but the Go WAV encoder hardcoded 24000 Hz. Every piper voice was
therefore written with a wrong header and played back at the wrong pitch/speed.
Read piper.sample_rate from the model's GGUF metadata at Load via the vendored
gguf-parser-go and use it for the WAV header, falling back to the 24 kHz default
for the other CrispASR TTS engines (vibevoice/orpheus/chatterbox/qwen3-tts) that

Neither the sherpa-onnx nor the speaker-recognition backend had a

Silicon.
Both backends build on darwin/arm64:
- sherpa-onnx (Go) already fetches the onnxruntime osx-arm64 runtime in its
Makefile; it only needed a darwin matrix entry (build-type metal, lang go,
like whisper and silero-vad).
- speaker-recognition (Python) needed a requirements-mps.txt so the mps build

onnxruntime-gpu pulled by its base requirements (which does not).
Add both to the includeDarwin build matrix, wire the metal capability and

* 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.

* 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).

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.

speechStreamer (reasoning-stripped transcript deltas + sentence-piped TTS),
and emits the terminal events. Tool turns and non-streaming pipelines keep
the existing buffered path unchanged, so this is strictly opt-in.

* fix(realtime): register pipeline streaming/thinking config fields
TestAllFieldsHaveRegistryEntries (core/config/meta) requires every config
field to have a meta registry entry. The four new pipeline fields
(disable_thinking, streaming.{llm,tts,transcription}) had none, failing
tests-linux/tests-apple. Add toggle entries for them.
Also handle the os.Remove return in realtime_speech_test.go to satisfy
errcheck (golangci-lint).

* fix(realtime): always strip reasoning from spoken output
disable_thinking maps to ReasoningConfig.DisableReasoning=true on the LLM
config, which the backend reads as enable_thinking=false. But the realtime
handler reads that SAME config to drive reasoning extraction, and there
DisableReasoning=true means "skip stripping". PredictConfig() returns this
LLM config, so both the streamed (speechStreamer) and buffered realtime
paths stopped stripping <think>…</think> exactly when disable_thinking was
on — leaking raw reasoning to the client whenever the model ignored the
enable_thinking hint (e.g. lfm2.5).
Add spokenReasoningConfig() which clears DisableReasoning for extraction
(keeping custom tokens/tag pairs) and route both realtime paths through it.
Spoken output now always strips reasoning, independent of the backend
suppression hint.

* fix(realtime): clean TTS temp path before read (gosec G304)
emitSpeech reads the WAV file the TTS backend wrote. The read moved here
from realtime.go, so code-scanning flagged it as a new G304 alert even
though the path is backend-controlled (a temp file), not user input.
Wrap it in filepath.Clean — a real path normalization that also clears
the alert, keeping with the repo's no-#nosec convention.

* refactor(realtime): buffer whole message for TTS, drop sentence segmenter
Per review (richiejp): the sentence segmenter pipelined unary TTS by
splitting on ASCII .!?/newline, which does nothing for languages without
those boundaries (CJK/Thai) — there it already degraded to buffering the
whole message anyway.
Replace it with a uniform model: stream the LLM transcript live, buffer the
full message, then synthesize it once. emitSpeech already streams the audio
chunks when the backend implements TTSStream and falls back to a single
unary delta otherwise, so this is real streaming TTS where supported and a
clean whole-message synthesis elsewhere — no per-sentence emulation, no
language assumptions. speechStreamer becomes transcriptStreamer (transcript
deltas only); the whole-message synthesis moves into streamLLMResponse.

* feat(realtime): stream tool-call turns via tokenizer-template autoparser
Per review (richiejp): tool-call deltas exist, so streaming should work with
tools too. It does — for models that use their tokenizer template. The C++
autoparser then clears reply.Message and delivers content + tool calls via
ChatDeltas, so the streamed transcript carries only spoken content (no
tool-call JSON leak) and the tool calls are parsed from the final response.
- Drop the len(tools)==0 gate; stream when no tools OR use_tokenizer_template
(grammar-based function calling still buffers, since its call is emitted as
JSON in the token stream and would leak into the transcript).
- streamLLMResponse takes tools/toolChoice/toolTurn, reads ChatDelta content
in the token callback, parses tool calls from the final ChatDeltas, and
creates the assistant content item lazily so a content-less tool turn emits
only the tool calls.
- Extract emitToolCallItems from the buffered path so both paths finalize tool
calls, response.done, and server-side assistant-tool follow-ups identically.

* feat(realtime): script-aware clause chunking + streamed-reply fixes
Opt-in pipeline.streaming.clause_chunking splits the streamed LLM reply
into speakable clauses and synthesizes each as soon as it completes,
lowering time-to-first-audio instead of buffering the whole message. The
splitter is script-aware (rivo/uniseg, pure Go): UAX#29 sentence
segmentation handles CJK 。！？ with no whitespace, CJK clause
punctuation (，、；：) and Thai/Lao spaces give finer cuts, and a UAX#14
line-break cap bounds an over-long punctuation-less run. Unlike the old
ASCII .!?/newline segmenter (dropped in 076dcdbe) it does not degrade to
whole-message buffering for CJK/Thai; scripts needing a dictionary
(Khmer/Burmese) stay buffered until a space or end-of-message. Clauses
are synthesized synchronously in the token callback (the LLM keeps
generating into the gRPC stream meanwhile), so audio still starts
mid-generation. Off by default — the whole-message path is unchanged.
Also fix the streamed-reply path and the Talk page:
- Don't swallow streamed autoparser content as reasoning: the
tokenizer-template path already delivers reasoning-free content via
ChatDeltas, so prefilling the thinking start token re-tagged it as an
unclosed reasoning block, leaving no spoken reply. Disable the prefill
on that path; closed tag pairs are still stripped (#9985).
- Generate collision-free realtime IDs (16 random bytes) instead of a
constant, so per-item bookkeeping (cancel, conversation.item.retrieve)
works.
- Key the Talk transcript by the server item_id and upsert entries.
Realtime events arrive over a WebRTC data channel — outside React's
event system — so React defers the setTranscript updaters while
synchronous ref writes in handler bodies run first; the old
index-tracking ref rendered a duplicate assistant bubble on
completion. Upserts by item_id are idempotent and order-independent.
- Drop the partial assistant bubble on a cancelled response (barge-in):
the server discards the interrupted item and sends response.done with
status "cancelled"; mirror that in the UI so the regenerated reply
isn't rendered as a second assistant message.

fix(vllm): restore compatibility with vLLM >= 0.22 (get_tokenizer moved)
vLLM 0.22 moved get_tokenizer from vllm.transformers_utils.tokenizer
to vllm.tokenizers. Since the backend requirements install vllm
unpinned, freshly built/installed vllm backends currently fail to
start with ModuleNotFoundError: No module named
'vllm.transformers_utils.tokenizer' (surfacing as 'grpc service not
ready' when loading a model).
Use the same try/except version-compat import pattern already used
elsewhere in this file: try the new vllm.tokenizers location first and
fall back to the pre-0.22 path.
Tested on a DGX Spark (GB10, ARM64) with the
cuda13-nvidia-l4t-arm64-vllm backend and vllm 0.22.0: model load, chat
completions and tool calls all work with this patch applied.

fix(distributed): track in-flight for non-LLM inference methods
InFlightTrackingClient only wrapped a subset of the grpc.Backend
inference methods (Predict, Embeddings, TTS, AudioTranscription, Detect,
Rerank, ...). Methods like VAD were left as embedded passthrough, so
track() never ran for them.
In distributed mode every model is loaded with in_flight=1 as a
reservation; that reservation is only released by the OnFirstComplete
callback, which fires after the first *tracked* inference call completes.
A VAD-only model (e.g. silero-vad) never calls a tracked method, so the
reservation is never released and in-flight stays pinned at 1 forever -
which also blocks the router's idle-eviction logic.
Wrap the remaining unary inference methods (VAD, Diarize, Face*, Voice*,
TokenClassify, Score, AudioEncode, AudioDecode, AudioTransform) with the
same track()/reconcile() pattern. The three bidi-stream constructors
(AudioTransformStream, AudioToAudioStream, Forward) are deliberately left
as passthrough - their inference spans the stream lifetime, not the
constructor call, so track() there would fire onFirstComplete before any
data flows.
