* 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).

chore(recon): re-pin voice/face-detect to squashed release commits
The voice-detect.cpp and face-detect.cpp engine repos were squashed to a single
release commit, which orphaned the previous pins (voice 3d51077, face 06914b0).
Re-pin to the new single-commit SHAs (voice 1db1759, face e22260d).
These also fold in a real correctness fix: the persistent graph-cache fingerprint
now includes op_params, so two structurally identical GGML_OP_CUSTOM graphs (a
blocked 3x3 vs a blocked 1x1 strided conv) can no longer false-hit the cache and
replay the wrong kernel. voice CI was failing test_blocked/conv1x1_s2 with an
out-of-bounds write on the GGML_NATIVE=OFF build; both engine repos are now green
and WeSpeaker embed parity is 1.0 vs golden.

* 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(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

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.

* chore(recon): bump voice-detect pin to ERes2Net blocked-default (30beecd)
Defaults VD_ERES2NET_BLOCKED ON: routes the ERes2Net Res2Net body through the
blocked nChw16c AVX-512 directconv island instead of the 1x1 mul_mat fast path
(CONT-transpose + skinny low-K GEMM). On the shipped GGML_NATIVE=OFF build (ggml
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
golden), so registered voices + verify/identify thresholds are unaffected. The
prior default-OFF rested on a stale comment whose 23pct regression only held on
the non-shipping GGML_NATIVE=ON build.

The macOS branch hardcoded WHISPER_LIBRARY=$CURDIR/libgowhisper-fallback.dylib,

the Go loader panicked at runtime ("dlopen ...dylib: no such file") and the

VAD on darwin. Pick whichever of .dylib/.so is present so it is robust to the

fix(backends): darwin packaging for silero-vad
silero-vad was the last Go backend with Linux-only darwin packaging:
- package.sh fell through to "Could not detect architecture" -> exit 1 on
macOS (no Darwin branch), so its darwin image never packaged.
- run.sh exported LD_LIBRARY_PATH, which macOS dyld ignores, so the bundled
libonnxruntime.dylib couldn't be found at runtime.
Add a Darwin branch to package.sh (skip the glibc/ld.so bundling; add an
@loader_path/lib rpath so @rpath resolves to package/lib/) and a
DYLD_LIBRARY_PATH branch to run.sh — mirroring the piper darwin fix (#10525).

The metal-darwin-arm64-piper backend crashed at launch on macOS:
DYLD "Library missing"
Library not loaded: @rpath/libucd.dylib
Referenced from: .../piper
Reason: no LC_RPATH's found
The piper binary links libucd, libespeak-ng, libpiper_phonemize and
libonnxruntime via @rpath, but ships with no LC_RPATH, so dyld cannot
expand @rpath and aborts before piper runs. The libraries themselves are
already bundled in package/lib/ by package.sh.
Additionally, package.sh's architecture detection only handled the Linux
glibc loaders (/lib64/ld-linux-x86-64.so.2, /lib/ld-linux-aarch64.so.1)
and otherwise hit `echo "Error: Could not detect architecture"; exit 1`,
so on macOS packaging failed outright.
Add a Darwin branch (before the Linux checks) that skips the glibc/ld.so
bundling macOS has no use for and instead runs
`install_name_tool -add_rpath @loader_path/lib` on the piper binary, so
@rpath resolves to the bundled package/lib/ directory.
Also mirror sherpa-onnx/opus in run.sh: export DYLD_LIBRARY_PATH on
Darwin (LD_LIBRARY_PATH is Linux-only) as a defensive fallback.
Validated by hand on Apple Silicon: with the rpath added, piper
synthesized a real WAV. The darwin build is validated in CI.

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.

fix(backends): quote $CURDIR in run.sh so backends work in paths with spaces
The backend launcher scripts derive their own directory with
CURDIR=$(dirname "$(realpath $0)") and then referenced it unquoted as
$CURDIR (e.g. [ -f $CURDIR/lib/ld.so ], export LD_LIBRARY_PATH=$CURDIR/lib:...,
exec $CURDIR/<binary> "$@"). When a backend is installed under a path that
contains a space - notably macOS's ~/Library/Application Support/... - bash
word-splits the unquoted $CURDIR, so the test builtin fails with
"binary operator expected" and exec tries to run ".../Library/Application",
yielding "No such file or directory". The backend never starts, surfacing as
a gRPC "service not ready" error and an HTTP 500. Quote $CURDIR (and the
realpath "$0") in every affected run.sh; no logic changes.

The parakeet-cpp backend had no macOS support and panicked at startup on
Apple/Metal nodes when purego.Dlopen could not find "libparakeet.so".
Fix it across the same four layers the sibling voxtral backend already

(runtime.GOOS), libparakeet.so elsewhere; PARAKEET_LIBRARY still wins.
- Makefile: also stage the built libparakeet.dylib next to the Go sources.
- package.sh: accept either the Linux .so[.X.Y] or the macOS .dylib when
bundling instead of hard-failing when no .so is present (the macOS case);
note that on Darwin only system frameworks are linked.
- run.sh: on Darwin set DYLD_LIBRARY_PATH and PARAKEET_LIBRARY to the
packaged .dylib; keep LD_LIBRARY_PATH + .so on Linux.
Mirrors backend/go/voxtral.

* fix(backends): darwin/metal support across purego Go backends
The parakeet-cpp fix in the previous commit was an instance of a bug
shared by nearly every purego/dlopen Go backend: the dlopen target was
hardcoded to a .so name and run.sh exported only LD_LIBRARY_PATH, so the
backend panicked at startup on macOS/Apple-Metal nodes (dyld needs the
.dylib name and DYLD_LIBRARY_PATH). voxtral was the only backend handling
this correctly.
Apply the same four-layer fix (mirroring backend/go/voxtral) to the
remaining affected backends:
whisper, sherpa-onnx, ced, stablediffusion-ggml, vibevoice-cpp,
qwen3-tts-cpp, omnivoice-cpp, crispasr, acestep-cpp, locate-anything-cpp,
depth-anything-cpp, rfdetr-cpp, sam3-cpp, localvqe
Per backend:
- main.go (sherpa-onnx: backend.go, two libraries): default the dlopen
target to the .dylib on darwin (runtime.GOOS), .so elsewhere; the
existing <BACKEND>_LIBRARY env override still wins.
- run.sh: on Darwin set DYLD_LIBRARY_PATH and point <BACKEND>_LIBRARY at
the packaged .dylib; keep LD_LIBRARY_PATH + the Linux CPU-variant
(avx/avx2/avx512) selection unchanged in the else branch.
- package.sh: also bundle the .dylib and stop hard-failing when no .so is
present (the macOS case).
- Makefile: also stage the built .dylib.
Notes:
- stablediffusion-ggml and acestep-cpp build their lib as a CMake MODULE,
which emits .so (not .dylib) on macOS; run.sh prefers .dylib and falls
back to .so so both layouts work.
- sherpa-onnx was already partly darwin-aware (Makefile/package.sh); only
run.sh and the two dlopen defaults needed fixing.
Linux behavior is unchanged. Verified gofmt-clean and
`CGO_ENABLED=0 go build` for every backend.

The supertonic Go TTS backend dlopens ONNX Runtime, but its runtime and
packaging scripts were Linux-only: run.sh exported LD_LIBRARY_PATH, pointed
ONNXRUNTIME_LIB_PATH at libonnxruntime.so, and always tried the ld.so exec
path, while package.sh hard-failed on any non-Linux host. On macOS dyld has
no ld.so loader, uses DYLD_LIBRARY_PATH, and ONNX Runtime ships as a .dylib.
This applies the same purego .dylib/DYLD_LIBRARY_PATH fix that PR #10481
landed for 15 other ONNX/purego backends (sherpa-onnx, silero-vad, etc.) but
which omitted supertonic:
- run.sh: on darwin export DYLD_LIBRARY_PATH and point ONNXRUNTIME_LIB_PATH
at libonnxruntime.dylib; guard the ld.so exec path to Linux only.
- package.sh: recognize Darwin instead of erroring out; the bundled .dylib is
resolved via DYLD_LIBRARY_PATH, no glibc/ld.so to bundle.
- helper.go: platform-native default library extension (dylib on darwin) for
the last-resort dlopen fallback.
It also wires the darwin CI build and gallery entries, resolving the
inconsistency where backend/index.yaml advertised metal for supertonic but no
includeDarwin matrix entry built the image:
- .github/backend-matrix.yml: add the -metal-darwin-arm64-supertonic Go entry.
- backend/index.yaml: declare metal capabilities and add the concrete
metal-supertonic / metal-supertonic-development child entries.
The Makefile already detects Darwin/osx/arm64 and stages the per-OS ONNX
Runtime tarball, mirroring sherpa-onnx, so no Makefile change is required.

multipart audio upload, temp-files it, resolves the model config and
calls the SoundDetection RPC; returns {model, detections[]} JSON.
- Backend wrapper: core/backend/sound_classification.go (ModelSoundDetection)

* feat(ced): realtime sound-event detection over the websocket API
When a realtime pipeline configures a sound-classification model, each
VAD-committed utterance (the same window the transcription path produces)
is also run through the CED sound-event classifier and the scored AudioSet
tags are emitted as a new server event. No new backend rpc is needed: the
SoundDetection gRPC method already exists on this branch.
- config: add Pipeline.SoundDetection (yaml/json sound_detection,omitempty)
beside Transcription/VAD.
- realtime: add Model.SoundDetection(ctx, audio, topK, threshold) to the
ModelInterface; implement it on wrappedModel and transcriptOnlyModel by
calling backend.ModelSoundDetection with the session's sound-classification
model config (mirrors how Transcribe dispatches). Load the optional config
in newModel / newTranscriptionOnlyModel; nil config keeps it additive.
- types: add ConversationItemSoundDetectionEvent (item_id, content_index,
detections[]{label,score,index}) with type conversation.item.sound_detection,
its ServerEventType constant and MarshalJSON, mirroring the transcription
completed event.
- realtime: add emitSoundDetection (unary path: classify the committed window,
build the event, t.SendEvent) and wire it at the utterance-commit hook right
after emitTranscription; gated on session.SoundDetectionEnabled (resolved
from Pipeline.SoundDetection at session setup, defaults top_k=5, threshold=0).
Its error is logged via xlog but never aborts the turn.

classifier error) plus a SoundDetection method on the fakeModel double.

* 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

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

* 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

The parakeet-specific word accessors can return stale initialisation
data (model name, binary blobs) for segments with no real speech.
Add isValidWord() to filter out words that have:
- empty or whitespace-only text
- U+FFFD replacement characters (from binary data scrubbing)
- negative timestamps
- zero duration (end <= start)
Also skip empty segments entirely when they have no recognisable
content (empty text AND no valid words), preventing spurious subtitle
entries like '00:45:33,592 --> 00:45:33,592 parakeet@rH\u000b\ufffdI'.
Applies to both AudioTranscription and AudioTranscriptionStream.

* feat(gallery): add Depth Anything V2 models + bump native version
Add Depth Anything V2 (DA2) support to the depth-anything backend. DA2 is
depth-only (no camera pose, no confidence) and ships both relative
(relative inverse depth) and metric (depth in metres) variants. The Go
backend is model-agnostic, so no backend code changes are required — only
a native version bump and new gallery entries.
- backend/go/depth-anything-cpp/Makefile: pin DEPTHANYTHING_VERSION to the
depth-anything.cpp commit that adds the DA2 engine + C-API routing
(e3dec57f13a52366bbc4f279ef44804915960a6b, kept alive by the upstream tag
da2-support so it survives a squash-merge).
- gallery/index.yaml: add 12 DA2 entries (4 base quants, small, large, plus
Hypersim indoor and VKITTI outdoor metric models in S/B/L). Metric models
carry the metric-depth tag; none carry camera-pose.

* feat(crispasr): add word-level timestamp support
Add word-level timestamp extraction to the crispasr backend by calling
the CrispASR C library's word accessor functions that are already
exported by libgocraspasr but were not previously bound by the Go
wrapper.
Two families of word functions are supported:
1. Session-based (get_word_count/text/t0/t1) — works per-segment for
whisper-like backends.
2. Parakeet-specific (get_parakeet_word_count/text/t0/t1) — returns a
global word list for TDT/CTC/RNNT parakeet models where the session
API does not expose per-segment word data.
The Go code tries session-based first and falls back to parakeet-specific
when the session word count is zero.
Depends on #10402 (grpc server Words forwarding) for the words to reach
the HTTP response.

* fix(crispasr): use portable sed -i.bak for macOS compatibility
BSD sed requires -i '' for in-place editing while GNU sed uses -i.
Replace with -i.bak which works on both platforms, then remove the
backup file.

Vulkan backends bundled their own loader and ICD manifests but neither the
Mesa driver the manifests point at nor a way to make the loader find them,
so on a runtime base image without Mesa the loader enumerated zero devices
and the GPU silently fell back to CPU (only NVIDIA worked, since its ICD is
injected by the container toolkit).
- scripts/build/package-gpu-libs.sh: for each installed ICD manifest, bundle
the driver .so its library_path names — no hard-coded, platform-dependent
soname list — plus that driver's ldd dependencies, skipping manifests whose
driver isn't installed. Rewrite each library_path to a bare soname so the
bundled driver resolves via the LD_LIBRARY_PATH run.sh already sets.
- .docker/install-base-deps.sh, backend/Dockerfile.golang,
backend/Dockerfile.python: install mesa-vulkan-drivers in every Vulkan
builder so the driver + manifests exist to be packaged (the LunarG SDK
ships only the loader and shader tooling).
- pkg/model/process.go: when a backend ships vulkan/icd.d/, point the loader
at it via VK_DRIVER_FILES/VK_ICD_FILENAMES at launch (no-op otherwise).
Covered by pkg/model/process_vulkan_test.go.
- backend/go/parakeet-cpp/package.sh: complete the L0 stub (was missing the
libc-family ldd walk + GPU-lib packaging) by mirroring whisper, so the
vulkan-parakeet image actually bundles its GPU runtime.
