Code scanning flagged seven issues in the new backend:
- G115 text.go: tool-call indexes and tokenize lengths come from the
upstream server as int and were cast straight to int32. Add clampInt32 so
an absurd upstream value saturates instead of wrapping.
- G115 live.go: the int16 -> uint16 cast in PCM16 encoding is a deliberate
two's-complement reinterpretation of an already clamped sample; mark it
with #nosec and say so.
- G304 proxy.go, media.go, client.go: api_key_file comes from the model
config, and the media input and output paths are files core staged or
chose for the call. None are caller-supplied. Clean the paths and add
#nosec with that reason, as core/gallery and the sound classification
endpoint already do.
- G306 media.go: write generated media 0o600. Core runs as the same user
and serves the file itself.
gosec reports 0 issues for backend/go/localai-proxy and
core/services/failover. The G104 once reported for failover/prober.go is
no longer present.

The failover prober cuts upstream_url at /v1, but Load kept the path, so
an upstream_url ending in /v1 probed healthy while every request went to
/v1/v1/... and got a 404, which never trips the target. Cut the path at
/v1 in Load too, with a warning.

A caller that gives up before the ready ack now ends the call with Canceled
and closes the upstream socket, and setup has a 3 minute default bound when
request_timeout_seconds is unset, so a hung upstream cannot hold the call
or block failover. A closing session now waits only for a turn the upstream
committed (or is still speaking), not for turns it discarded. Audio held
before the ready ack is capped at 5 s, and NaN samples become silence.

AudioTranscriptionLive opens <upstream>/v1/realtime?model=<realtime_pipeline>
as a transcription session with server VAD, forwards PCM as base64 PCM16
appends, and maps transcription deltas and completions to Delta/Eou. Closing
the send side waits briefly for an in-flight utterance, then sends the final
text. An upstream error, failed transcription or disconnect ends the stream
with Unavailable so failover reopens on the next target.

Detect/Depth/FaceVerify/FaceAnalyze forwarded the bare base64 core hands the
backend, but the upstream's own REST handlers only accept a URL or a
data:...;base64, string, so every real call 400'd. Wrap the payload as a
data URI (sniffing its MIME type) before sending it.
Depth requests for exports/dst now return Unimplemented: those files are
written to the upstream's own local disk and are unreachable from here, so
failover should move to a local target instead.
Generation replies that hand back a URL are now re-fetched by path only,
checked against the upstream's known generated-content prefixes, instead of
stripping the configured base as a literal string prefix — the old approach
broke (or silently trusted an arbitrary host) the moment the upstream
advertised a different base via LOCALAI_BASE_URL, a reverse proxy, or
X-Forwarded-Host.

The proxy now forwards TTS, streaming TTS, sound generation,
transcription (plain and streaming), diarization, VAD, sound
detection and audio transforms to the upstream LocalAI.
Streaming TTS passes the upstream WAV bytes through unchanged. A
streaming transcription that stops before its final frame, or sends
an error frame, fails with Unavailable instead of ending as a short
success. Transcription always sends diarize, because the upstream
treats a missing field as true. Audio transforms also download the
separation stems the upstream names and write them beside Dst.
Sound generation from a source clip returns Unimplemented, because
the REST endpoint has no field for the clip.
The multipart helper now takes repeated fields and several files.

Treating ResourceExhausted as a capability gap skipped the target
without counting a failure, so a target that stays rate limited or out
of memory kept its traffic. It is now an ordinary retryable failure:
the request moves to the next target and the exhausted one trips.

Rerank no longer sends top_n 0, which the upstream rejects. A
mid-stream upstream error frame now fails the call instead of ending
it as a short success. Temperature 0 is forwarded. An upstream 429
becomes ResourceExhausted, which failover skips like Unimplemented.
A localai-proxy config sends its own name upstream when upstream_model
is unset, and a chat proxy defaults to the tokenizer template so chat
reaches the upstream as messages.

* feat(vllm-cpp): unify decision pipeline through Score RPC with vllm_decide ABI v29
Replace the model-specific SystemOne gRPC approach with a generic Score
RPC extension. The pre-existing Score RPC (previously unused by any
backend) now carries question_type and response_json fields:
- question_type="systemone" routes kev/laya decision-pipeline requests
through the unified vllm_decide C ABI (v29), returning the full
response JSON in response_json.
- question_type empty routes cua-s1-forms candidate scoring through the
same vllm_decide ABI, returning CandidateScore probabilities.
The vllm-cpp backend's Score() method calls vllm_decide and dispatches
by architecture internally. The /v1/systemone HTTP endpoint checks
whether the model's backend supports Score; if so, it forwards the raw
request JSON and returns the backend response as-is. Other backends
fall through to the existing NER-based path.
This mirrors the vllm.cpp C ABI refactor (PR #3301) that replaced
vllm_systemone + vllm_score with a single vllm_decide function. The
purego bindings bump abiVersion from 27 to 29 and resolve vllm_decide
and vllm_decide_free symbols.
Also fixes validModelPath to accept cua-s1-forms.json and
rl_agent_config.json alongside config.json, matching the engine's
model_loader.cpp config-filename ordering.

The previous patch only removed DECL_FATTN_VEC_CASE_D512 for turbo2_0
and turbo3_0 V cache types. turbo4_0 also overflows shared memory
(0x10100 bytes > 0xc000 max), causing ptxas errors on CUDA 12/13.
Additionally, the previous patch was incomplete: it only removed the
template instantiations but not the dispatch calls in fattn.cu or the
extern declarations in fattn-vec.cuh. This caused linker errors
(undefined reference to ggml_cuda_flash_attn_ext_vec_case_d512).
This patch removes all three layers for all turbo V types:
- Template instance .cu files (DECL_FATTN_VEC_CASE_D512)
- Dispatch calls in fattn.cu (FATTN_VEC_CASE_D512)
- Extern declarations in fattn-vec.cuh (extern DECL_FATTN_VEC_CASE_D512)

* fix(omnivoice-cpp): workaround GGML_SOURCE_DIR for nested builds
omnivoice.cpp 3ac485d changed from a relative add_subdirectory(ggml)
to CMAKE_SOURCE_DIR-based path resolution. CMAKE_SOURCE_DIR points to
the top-level project, not the current subdirectory, so when
omnivoice is consumed via add_subdirectory() the build fails:
add_subdirectory given source ".../omnivoice-cpp/ggml"
which is not an existing directory.
Set GGML_SOURCE_DIR to the correct path before add_subdirectory so
the upstream code picks it up from the cache. This is a workaround
until ServeurpersoCom/omnivoice.cpp#20 is merged upstream.

* feat(vllm-cpp): add GLiNER2.5 NER via TokenClassify

TokenClassifyEntity messages, and frees the result.

structs; vllmGlinerNer and vllmNerResultFree purego bindings; abiVersion
bumped 26 -> 27.

Add POST /v1/systemone, /v1/systemone/permute, and
/v1/systemone/separate to LocalAI, mirroring the kev project's
structured-extraction API. Each endpoint runs zero-shot NER over the
rendered state text and builds kev-compatible answers for three question
types: noul (binary entity presence), choice (pick one option), and
score (pick one level).
The TokenClassifyRequest proto gains a `repeated string labels` field so
each question can supply its own labels at inference time, and
TokenClassifier gains TokenClassifyWithLabels for per-call label
selection. The vllm-cpp backend uses request labels when non-empty,
falling back to configured ner_labels then the built-in defaults.
Helpers (renderState, softmax, choiceConfidence, scoreConfidence, r2)
are ported from kev/api.py and mirrored in vllm.cpp's api_server.cpp so
both servers produce the same answer shape.

* fix(vllm-cpp): use instruction text as NER label in SystemOne handler
The SystemOne handler was passing question IDs as NER labels for noul
questions and bare key names for choice questions, so the model never
matched any entities. Port the label mapping from vllm.cpp's
ParseSystemOneBody:
- noul: use the rendered instructions field (with instr alias) as the
NER label, not the question ID
- choice: use optionText(name, desc) — "name: description" or "name"
when the description is null/empty — not the bare key
- score: already correct (rendered criteria text)
- permute: shuffle indices and build parallel key/label arrays so the
NER call uses the optionText labels while the response is keyed by
the original option names
Also add the instructions field to the SystemOneQuestion schema struct
(accepted alongside the instr backward-compat alias).
Verified end-to-end against the real GLiNER2.5 model: noul questions
now find "Apple Inc. is" (organization, 0.999) and "Tim Cook is"
(person, 0.852) where they previously returned zero entities.

sglang 0.5.20 moved its config tier from dataclasses to msgspec.Struct
(sgl-project/sglang#38753). _apply_engine_args validates engine_args keys
via dataclasses.fields(ServerArgs), which raises TypeError there. That
call runs on every LoadModel, so no model loads at all on the sglang
backend once sglang >= 0.5.20 is installed, and the error surfaces as a
generic "Unexpected <class 'TypeError'>" that does not name the cause.
Introspect both shapes: msgspec structs carry their field names in
__struct_fields__, so key validation and the close-match suggestion keep
working, and older dataclass-based sglang stays supported.
Adds a test that pins the msgspec path with a stand-in, so it is covered
regardless of which sglang version is installed.
