mudler-agentandEttore Di Giacinto 2cadf319a0 feat(realtime): LFM3-Audio speech-to-speech on llama.cpp, remove liquid-audio (#12958)
* chore(backends): remove the liquid-audio Python backend

The backend targets liquid-audio, which loads LFM2 checkpoints only.
Remove its directory, the gallery file and the LFM2.5-Audio model
entries, the library and generated backend gallery entries, the
backend matrix and CI job, the Makefile targets and the golden test
fixtures that listed it.

* refactor(config): drop liquid-audio from capabilities, importers and UI

With the liquid-audio backend gone, remove its capability entry, its
importer, its artifact-gate entry and the realtime_audio heuristic
that only matched that backend. realtime_audio is now set only
through known_usecases. Update the Talk and fine-tuning pages, the
docs and the swagger text that named the backend.

* chore(llama-cpp): bump llama.cpp to e486a4b5

Move the llama.cpp pin to e486a4b559617dc88bf79978996f6c670b6bbc9d,
the master head of 2026-10-28. It contains the LFM3-Audio support
(ggml-org/llama.cpp#31257) and the realtime server split
(ggml-org/llama.cpp#31269).

The score task patch is regenerated against the new pin. It applies
with git apply and with patch -p1, with no offset and no fuzz. Its
hunks in server-task.h and server-context.cpp were rebased by hand
next to SERVER_TASK_TYPE_REALTIME and the control dispatch.

The C++ backend was built on CPU for this change: the llama, mtmd and
server-context libraries and the grpc-server binary link.

* feat(llama-cpp): compile server-realtime.cpp into grpc-server

server-context.cpp includes server-realtime.h, and its realtime slot
type is defined in server-realtime.cpp. Upstream compiles that file
into the server library. The gRPC server is one translation unit, so
it must include the file too, or the link fails.

The include is guarded by __has_include. Forks that predate the
realtime split do not ship the file, so they keep building as before.

* chore(llama-cpp): probe realtime and TTS voice support in prepare.sh

prepare.sh writes llama_compat.h from probes on the checkout. Add two:
LOCALAI_HAS_REALTIME (SERVER_TASK_TYPE_REALTIME in server-task.h) and
LOCALAI_HAS_TTS_VOICE (set_voice in mtmd-helper.h). The probes let the
gRPC server choose the realtime and voice code paths per checkout, so
forks without them keep compiling.

* feat(llama-cpp): advertise speech recognition and speech-to-speech

llama-cpp now registers the AudioTranscription and AudioToAudioStream
RPCs, with the transcript and realtime_audio usecases. The default
usecase stays chat, so a plain GGUF is still a chat model. The
backend implements the RPCs in a follow-up change; until then the
calls return UNIMPLEMENTED.

* feat(config): add pipeline.any_to_any for speech-to-speech models

A realtime_audio model that serves the whole speech loop itself sets
pipeline.any_to_any. The flag is off by default, so chained pipelines
and existing realtime_audio configs are unchanged. The realtime_audio
heuristic stays explicit: a llama-cpp model is never a Talk-page model
unless known_usecases says so.

* feat(config): read the audio encoder and speech-to-speech projector flags

Add HasAudioEncoderProjector for clip.has_audio_encoder and
HasSpeechToSpeechProjector, which requires the LFM3 audio encoder
family together with the gen-audio decoder. Qwen3-TTS sets both encoder
flags too, so the flags alone cannot tell it apart from LFM3.

An mmproj that carries the LFM3 audio encoder and the gen-audio decoder
now imports with known_usecases realtime_audio, chat, transcript and
tts, pipeline.any_to_any: true, the parallel:2 option and the tokenizer
template. Other gen-audio projectors keep the TTS-only result, Qwen3-TTS
included. The probe runs against a local HTTP server in the tests.

* feat(llama-cpp): named-voice TTS and the LFM3 ASR prompt

Models without a speaker reference (LFM3-Audio) take a named voice
through their "tts" chat template instead of a reference file. The
request is validated with needs_reference=false, the prompt is rendered
with common_chat_get_tts_prompt(), and the voice is set on the gen-audio
input. Qwen3-TTS Base keeps the reference-file rule. The branch is
guarded by LOCALAI_HAS_TTS_VOICE, so forks without named voices keep the
old behaviour.

Transcription takes its prompt from common_chat_get_asr_prompt(). LFM3
gets a system turn that names the language and an empty user turn.
Qwen3-ASR's preset is unchanged: fixed user text, no system turn, and a
caller prompt is still appended after a newline. The preset call is
guarded by a new LOCALAI_HAS_ASR_PRESET probe.

The pure parts sit in tts_request_options.h and transcription_prompt.h,
with standalone tests run by backend/cpp/run-unit-tests.sh.

Add the test-extra-backend-llama-cpp-lfm3 target. It runs the tts,
ttsstream and transcription specs against LFM3-Audio GGUF weights. It is
a manual run and is not wired into CI.

* test(e2e): mock AudioToAudioStream and pending realtime S2S specs

The mock backend serves AudioToAudioStream deterministically: session
created, commit with RMS, a tool call on the first turn with tools, then
transcript pieces and paced 24 kHz tone frames, with response.cancel
ending a reply as cancelled.

The realtime S2S specs cover the mock and real-weights variants. They
skip until the /v1/realtime S2S path lands, so the mock suite stays
green in CI.

* feat(llama-cpp): speech-to-speech AudioToAudioStream on the realtime slot

Implement AudioToAudioStream on upstream's realtime slot, so a model
that answers after the audio (LFM3-Audio) can hold a conversation over
the existing duplex RPC. The proto schema does not change: tools travel
in the config, tool calls leave as function_call_arguments.done and tool
results arrive as a function_call_output item.

realtime_session.h keeps what needs no model: the turn text derived
from the chat template (with a tool turn), the conversation state, a
filter that keeps <tool_call> blocks out of the transcript and drops
audio produced inside them, and the translation of slot results into
events. grpc-server.cpp wires it to the slot with control tasks and
parses calls with the parser the chat template selects.

The unit test uses a fake renderer. A ctest-only check renders the real
LFM3 template and compares the slot text with the full render.

* feat(gallery): add the LFM3-Audio-2B entries

Two llama-cpp entries for LiquidAI/LFM3-Audio-2B-GGUF, the Q4_K_M
default (lfm3-audio-2b) and the Q8_0 build (lfm3-audio-2b-q8), both
with the Q8_0 audio projector. Each declares pipeline.any_to_any and the
realtime_audio, chat, transcript and tts usecases the importer writes
for an LFM3 projector, with parallel:2 and the tokenizer template. The
Q4 entry lists the Q8 one as a variant.

File sizes and sha256 come from the Hugging Face API for the pinned
repo revision. Speaker reference files and the VAD model are not part
of the entries: VAD stays optional.

* docs: describe LFM3-Audio speech-to-speech and its gallery entries

Adds a speech-to-speech section to the Realtime API page (any_to_any
configuration, VAD versus manual commit, tools, transcripts, barge-in,
limits), a pipeline.any_to_any row, a llama.cpp speech-to-speech row in
the compatibility table, and LFM3-Audio mentions on the TTS and ASR
pages. The feature is marked experimental: the behaviour follows the
backend session contract and has not been run with real weights.

* feat(realtime): run any-to-any models on AudioToAudioStream

A realtime_audio model with pipeline.any_to_any now opens one duplex
stream to the backend and keeps it for the session, replacing the
"any-to-any models not implemented" branch. The chained pipeline is
unchanged.

The endpoint forwards input audio (with a pre-roll from speech start
when a VAD model is set, otherwise every chunk and a client commit),
sends response.create, and turns the backend's events into the usual
realtime events: audio and transcript deltas, tool calls through the
existing function_call items, and a single response.done. A function
call output is forwarded before the next response. Barge-in sends
response.cancel ahead of the new speech and stops forwarding audio at
once. The user's speech is transcribed on the side and reported on the
user item; a failure there does not touch the response.

Server VAD is on only when pipeline.vad is set. Classifier mode,
compaction, streaming.llm, voice gating, sound detection and
semantic_vad are rejected for these models.

The mock backend now matches the llama.cpp contract (session.updated,
the cancel error when idle) and its VAD reports the loud stretches of
the audio, so the S2S e2e specs run a VAD turn. The specs are enabled.

* test(e2e): add the real-weights realtime S2S variant and the gRPC s2s spec

The realtime S2S specs now check reply audio on real models: duration,
loudness, clipping, and keywords found in the model transcript or in a
separate ASR of the output audio. run-realtime-lfm3.sh stages the llama-cpp
and sherpa-onnx backends, the LFM3-Audio files and the sherpa VAD, ASR
and TTS models, then runs the real variant. It is manual and never part of
CI: `make test-realtime` still filters out real-models.

The backend suite gains an s2s capability (spoken turn, tool call, tool
result, spoken answer over AudioToAudioStream) and optional TTS duration
and RMS bounds plus a transcript keyword check, all enabled for
test-extra-backend-llama-cpp-lfm3.

* test(e2e): expect the idle-cancel error from the mock S2S

The mock now answers a response.cancel with no reply running with
response_cancel_not_active, as the llama.cpp backend does. The cancel
spec still treated that cancel as a no-op and read the error as extra
data after the stream ended.

* feat(talk): show any-to-any models as one speech-to-speech model

/api/pipeline-models lists a pipeline.any_to_any model with any_to_any
set and its optional VAD. A realtime_audio model that is not any-to-any
is listed only when it has the four pipeline slots, since the session
takes the chained path for it.

The Talk page shows a speech-to-speech model as one model: no four-slot
view, the VAD slot only when a VAD model is set, and the female and male
voices offered. Without a VAD model the server does not detect turns, so
the page offers Done speaking, which sends input_audio_buffer.commit and
then response.create. Text-only replies stream through
response.output_text.delta and .done.

self_contained stays in the response for clients built before any_to_any.

* fix(realtime): refuse a llama-cpp realtime model without pipeline.any_to_any

* fix(realtime): hold manual-commit S2S audio until the commit

In manual-commit mode the endpoint streamed every appended chunk to the
backend, so input_audio_buffer.clear only emptied the Go buffer while the
model kept the audio, and idle audio filled its context between turns.
Keep the audio in the input buffer and send it, behind pending text and
tool-result items, when the client commits or asks for a response.

Frames and controls now go through one ordered write queue, so no gRPC
send happens under the audio buffer lock. A tool result created while a
VAD turn is open is refused with a clear error. When the stream ends
outside a response the session reports it and closes, and a bare EOF
from Send reports the status that Recv holds.

* test(e2e): make the mock S2S backend keep the llama-cpp session limits

The mock accepted what the real backend refuses and hid two endpoint bugs.
It now treats output_modalities from the config as a fixed session mode and
picks the default per response from the tools set at that time. A fixed text
plus audio mode with tools reads the tool call out loud. After the first
commit or message, session.update of instructions, voice or tools is an
error that does not belong to a response, committing an empty buffer is an
error, and response.create while a reply runs is refused. Errors of a
refused response.create carry response_scoped in their meta.

* fix(realtime): leave the S2S output mode to the backend unless the client sets one

The stream config sent text plus audio when the session had no tools yet.
The llama-cpp backend keeps a mode from the config as a fixed session mode,
and tools added later by session.update never cleared it. The model then
read tool calls out loud. Send output_modalities only when the client chose
them. The backend picks the default of each response from the tools it has
when the response starts.

* feat(llama-cpp): mark the realtime errors that answer a response.create

The error event now carries response_scoped: true when it ends the request
for a response (a refused response.create, a failed commit made by it, or
a stream failure). Other errors, such as a refused session.update or a
commit of an empty buffer, are not about a response and one that runs
keeps generating. The client needs the difference to know whether a
response.done is still coming.

* fix(realtime): end an S2S response only on the errors that belong to it

Every backend error ended the response in flight, although the backend
also reports errors about other things (a refused session.update, a commit
of an empty buffer) and goes on generating. The rest of the reply was lost
and the next response.create met either a refusal or the leftover events of
the old reply. End the response only on an error marked response_scoped,
forward the others to the client and keep waiting for response.done. Drop
the events buffered by an earlier response when a new one starts, and skip
the commit of a turn that forwarded no audio.

* fix(realtime): run the S2S input transcription detached from the commit slot

The commit waited for the side transcription of the user audio while it
held the commit slot, and response.create waits for that slot. The ASR
latency was added before every reply, and on a backend with few slots a
busy ASR task could stall the reply. The model already has the audio, so
run the transcription detached under the session context and release the
slot at once. The transcript is still reported on the user item.

* fix(realtime): stop an S2S reader leak and a cancel that waits on the write queue

The reader waited on a channel it closes itself when the events buffer was
full, so it outlived the session after a turn ended on an error or timed
out. It now also stops when the session closes.

Stopping a response sent the cancel through the write queue and waited for
it before the grace timer started. With backpressure on the stream the wait
never ended and nothing read the events meanwhile. The timer now starts
first and the cancel is only queued.

* feat(realtime): let a chained pipeline run without a VAD model

A pipeline that names no pipeline.vad failed to build, because the
VAD slot was always loaded, and a new session still started with
server_vad. The slot is now optional for chained pipelines as it
already is for any-to-any models: the session starts with turn
detection off and the client commits each turn. Turning server_vad on
for such a session is refused, and a switch to a pipeline without a
VAD drops turn detection.

* feat(gallery): add LFM3-Audio VAD and chained-pipeline entries

the turn detector), and lfm3-audio-2b-pipeline, -pipeline-vad and the
-q8 forms (the model chained through its own transcription, chat and
speech slots, with and without the VAD). The gallery has no
dependencies between models, so the VAD entries state that
silero-vad-ggml must be installed first.

Drop the variants list from lfm3-audio-2b: it let the installer pick
the larger Q8 build on any host with enough memory, so a plain install
of the Q4 entry did not get Q4. All entries are now independent. Tests

A response held the stream slot until it returned, and it ran the tool
calls from inside that scope. A server-side tool starts a follow-up

still held, so the client never got response.done. Run the tool calls
once the slot is free; the event order is unchanged.

* fix(realtime): end an S2S session whose stream dies, and stop queuing after close

A stream that died during a response left the session open: later
requests failed one by one and VAD frames kept being forwarded. The
response now ends the session through the transport, and enqueue drops
requests once the session is closed so the write queue cannot grow.

The writer is now the only caller of Send and of CloseSend. close()
used to call CloseSend while the writer could be inside Send, which
gRPC does not allow.

now claimed and queued under the audio lock only when no turn is open,

* feat(realtime): parse tool calls with the chat template, as upstream

Since ggml-org/llama.cpp#31287 the realtime server handles tools with
the parser and grammar of the chat template. Do the same in the
speech-to-speech stream instead of a hard-coded tag filter and a parse
of the whole text at the end.

- Each response gets a common_chat_session with the tools of the
  session and parallel calls. Its grammar and preserved tokens go into
  the sampling of the response, so the slot keeps the call tokens in
  the text and constrains the call.
- The text of the response is fed to the session piece by piece
  (task_result_state::update_chat_msg). Content deltas become the
  transcript; tool-call deltas are collected into one
  function_call_arguments.done per call at the end. Audio after the
  start of a call is dropped.
- A tool_choice of auto, none or required is accepted in the params of
  the config, in session.update and in response.create, with the
  response overriding the session.
- The tool turn is derived from a conversation in which the assistant
  called a tool, like upstream, not from a plain reply.
- response.done carries raw_text, everything the model wrote with the
  call markup, for a caller that parses it another way. If the parser
  throws, the rest of the response is content and the raw text is the
  way out.

ToolCallFilter is no longer used and goes in the next commit.

The unit tests cover the splitter contract (content, call deltas, the
final piece, whole characters only). realtime_chat_check feeds
LFM3-format text through the session in pieces of 1, 7 and all bytes
and checks the call, the transcript and the grammar.

* refactor(realtime): drop the tool-call text filter

The parser of the chat template now splits content from tool calls, so
ToolCallFilter, which looked for the literal <tool_call> tags, has no
caller. Remove it with its tests. Every case it covered (a call
between text, split tags, several calls, an unfinished call, text after
a call) is handled by the parser, and realtime_chat_check runs the
LFM3 format through it in pieces of different sizes.

* feat(realtime): fall back to the raw text for S2S tool calls

For an any-to-any model, the calls the backend parsed still win. When
there are none and the request had tools, parse the raw text that
response.done now carries the way the chained pipeline parses the text
of its LLM (CleanupLLMResult, ParseFunctionCall, ParseTextContent), so
a call format the backend parser does not know can still be served
with function.xml_format_preset or the other function settings of the
model. The content around the calls replaces the streamed transcript
only if the config captures it, as in the chained path.

Also pass tool_choice to the backend: the session mode with the stream
config and with session.update, and the mode of a response.create
override with that event. A named function cannot be forced, so it is
not sent.

* fix(functions): parse tool blocks that have text between them

The iterative XML parser stopped at the first scope block that was
preceded by text, so "<tool_call>A</tool_call> then <tool_call>B" gave
one call. Skip text between blocks once a call was found; text before
the first block still ends the parse as before. Blocks that follow each
other, or only whitespace, already worked.

Tests cover three calls back to back and with text between them, with
the lfm3 preset and with auto-detection. They also pin the current
reading of argument values: the parser has no tool schema, so a value
such as 42 or true is read as JSON even when the schema types it as a
string.

so the server parses the call format of the LFM3 chat template when the
backend returns no call (and in the chained pipeline entries, which use
the regular chat path). gallery/index.yaml is regenerated from the

* fix(functions): keep earlier calls when a later block does not parse

After a valid call, text that holds the opening tag again (a prose
mention, a markdown example, a malformed second block) made the parser
treat it as a new block, fail, and return no calls at all. Remember the
state after each complete block and fall back to it when a later one
fails: the calls found so far are kept, parsing stops there and the
remaining text stays in the content.

Text skipped between two valid blocks now goes to the content instead of
being dropped, so StripToolCallMarkup keeps it.

* fix(realtime): do not drop audio after a tool call started

In mixed mode the speech for text written before a call can still be
pending when the call starts, so dropping every audio frame after the
first call delta cut the speech while its transcript was sent. The
llama.cpp server never drops audio when it reads a result; do the same.
If a model speaks the call markup aloud, that is model behaviour to
observe on real weights, not something to filter here.

* fix(realtime): flush held-back text when a response is cancelled

The parser got is_partial=true on a cancelled response, so text it held
back (a possible start of a tag) never reached the transcript. The llama.cpp
server parses a cancelled response with is_partial=false; do the same. A
cancelled response still makes no tool call. The path where the parser
throws already sends the text as content and needs no change.

* test(realtime): stop the fake S2S stream from sending after Close

The barge-in spec failed now and then with a data race and "send on
closed channel": its script pushes audio from a goroutine, and the
session closes the stream while that goroutine still runs. A push now
does nothing once the stream is closed, and Close waits for a push in
flight. The production close order is right: the writer closes the
stream only after it stops sending.

* fix(realtime): align the S2S tool-call fallback with the backend

Four gaps in how the Go side reads the tool calls of an any-to-any reply:

- With tool_choice none (the response value wins over the session value)
  the backend builds no tool parser, yet the raw-text fallback still
  turned a call the model wrote into a function_call item. Skip it.
- Without a capture regex the fallback never cleaned the transcript, so the
  stored item and transcript.done kept the raw call markup. When the call
  is XML, use the text left after the markup is cut out; a reply that is
  only a call now has an empty transcript.
- A named function as tool_choice mapped to nothing, so the backend kept
  the previous mode. Refuse it with an error in session.update and
  response.create.
- A response-level tools list changed what the fallback looked for, but
  the backend only has the tools of the session. Use those in both.

The suite always registered the mock backend under the name llama-cpp, so
a run with REALTIME_S2S_MODEL set never reached the llama-cpp backend
found in REALTIME_BACKENDS_PATH. Register the mock only when that run is

The real run converts the input audio with ffmpeg. Check for it in the

* test(realtime): cover the tools path of a client session.update to the S2S backend

A tool call that never came back from an any-to-any model raised the
question whether the tools of the session reach the backend at all. Add a
spec that sends the session.update of the real-weights e2e (flat
Responses API tool, no session type) and checks that the backend gets
the tool in the chat-completions form.

Log the number of tools sent when the stream opens and when a
session.update carries them, so a run log shows it without reading the
wire. The "No tools received" line of the llama-cpp backend does not
show it: the server prints it for the input transcription request, which
has no tools by design.

* test(e2e): interrupt the chained pipeline reply while it is in flight

With unary stages, the default of the lfm3 pipeline gallery entries, the
chained pipeline synthesizes the whole reply and sends it as one audio
delta right before response.done. The barge-in spec waited for that
delta and then rendered the interruption with the TTS, so the first
response was already done when the speech started and ended completed
instead of cancelled. Real runs on a GPU showed it with both
quantizations.

For a pipeline, start the interruption at response.created, which comes
before the LLM and TTS stages. Render the interruption audio before the
first utterance is sent, so nothing sits between the reply and the
interruption. The any-to-any shape still waits for the first audio
delta, which that backend streams while it generates.

The check that the reply audio says what the transcript says needs a
shared word of 4+ letters. A short answer failed it: the model wrote
"Four" and the ASR heard "for". Compare numbers in one spoken form, so
digits, number words and their homophones match each other. A homophone
only counts when the other text has the number itself, so "for" on both
sides still shares nothing and the check does not pass on a stop word.

* fix(llama-cpp): ask LFM3-Audio for function calls when a realtime session has tools

The default system prompt of a realtime session was "Respond with
interleaved text and audio." whatever the tools. Under that prompt
LFM3-Audio answers in words ("I'll check the weather ...") and never
writes the call. The model card, and the llama.cpp realtime example
client, use "Respond with function calls, and interleaved text and
audio." when the session has tools, and the model then calls the tool.

Pick the default by the tools of the session, and treat the plain default
that the LocalAI server sends back as no choice: it follows the tools too,
also when they arrive with a session.update before the first audio. A
prompt the client wrote is kept as it is.

* fix(realtime): transcribe the input of an any-to-any turn between responses

The input transcript of a speech-to-speech turn ran at the same time as
the reply, on the same model. llama.cpp serves both from one context: the
realtime slot wants embeddings on, the chat slot of the transcript wants
them off, and each flip makes it reserve its compute buffers again. In a
GB10 run that was two reserves of about 175 ms per step, the reply fell to
2.6 tokens per second and the transcript to 380 ms per token, until the
transcript was done.

When pipeline.transcription is the model of the stream, run the transcript
after the response, or before one that is not started yet, and keep
responses out while it runs. A separate transcription model still runs in
parallel.

The previous change moved the same-model transcript after the response.
A client that reads until response.done then never saw
conversation.item.input_audio_transcription.completed: the transcript
was made (the log shows it) but sent after the end of the window.

Run it in line with the commit instead. A VAD turn transcribes and then
responds. A client response.create already waits for the commit slot, so
it starts once the transcript is out. The transcript event now comes
before any output of the response of its turn, for a manual commit and for
a VAD turn, and never overlaps the response on the llama.cpp context. A
transcription model of its own still runs in parallel.

* feat(realtime): transcribe the input of an any-to-any model only when asked

The stream answers from the audio, so the transcript of the input is for
the client only. On the model of the stream it is costly: llama.cpp
serves the transcript request and the realtime stream from one context
and rebuilds its compute buffers on every step while both are active.
On a GB10 that was 26 to 29 reserves of about 175 ms per turn, against 0
to 1 on the llama.cpp server, and the reply ran at a few tokens per
second.

An any-to-any model no longer fills pipeline.transcription with its own
name. Without it the session does not transcribe the input; with another
model it does, in parallel with the reply; with the model itself named it
does, before the reply. The reply transcript always comes from the stream.
The gallery entries set none, so they get the fast path.

The mock configs and run-realtime-lfm3.sh name a transcription model, so
the real-weights spec still covers the input transcript.

* fix(realtime): end a response as cancelled when a barge-in lands during the LLM call

The chained pipeline cancels the response context on a barge-in. When that
happens while the model is generating, the backend call fails with the
context error, and the response ended as failed: an error event and no
response.done. A client that waits for the terminal of the interrupted
response then waits forever. On a GB10 the q4 model answered before the
barge-in arrived, so only the slower q8 model showed it: the spec read
events for 30 s and timed out.

When the context is cancelled, a failed Predict call or a failed result is
a cancel, as the TTS step and the streamed LLM path already treat it. The
response ends with response.done{cancelled} and no error.

* test(e2e): wait for the input transcript that comes from a model of its own

stops reading at response.done saw no transcript in the VAD shape. Keep
reading, up to 30 s, until the transcript arrives. The contract is that it
comes, not when.

Add a guard spec for what the input transcription is handed: the whole
turn, in a WAV that says the rate it was recorded at (the session rate for
a client commit, 16 kHz for a VAD turn).

Stefan Walcz 6d7e8171be feat(agents): per-model output cap for agent job completions
Agent jobs (/api/agent/jobs, local and on distributed agent workers) run
cogito against a LocalAI client that sends no max_tokens of its own, so
every completion gets the client's fixed default of 16384. max_iterations
bounds the number of turns and loop_detection repeated tool calls, but
neither stops one completion that keeps generating, and 16384 is the same
for a small tool-picking model and a reasoning model that thinks at length.

Add agent.max_generation_tokens to the model config. When set, both job
paths apply it to the client with SetMaxTokens; requests that carry their
own cap still win, so cogito's length retry can raise it. Unset keeps
today's behaviour.

The specs run each job path against an MCP fixture and a recording LLM
endpoint and check the max_tokens the completions carry; they fail when
either call site drops the cap.

The Go side already forwards the request's effort as
Metadata["reasoning_effort"], but the sglang backend only read
enable_thinking: every level got the same model-level thinking_budget,
so low/medium/high produced identical reasoning.

- New model option `effort_budgets:low=…;medium=…;high=…` picks the
  budget of the request's level; unlisted levels and requests without an
  effort keep `thinking_budget`. Parsing reuses _parse_thinking_budget.
- A level listed in effort_budgets turns reasoning on for that request,
  so levels the Go side does not know cannot silently disable it.
- ApplyReasoningEffort now treats `xhigh` and `max` as thinking levels.
  Before, they left DisableReasoning unset, so with a model default of

Add --max-concurrent-backend-operations

* feat(galleryop): run backend operations in a bounded pool

One goroutine read both gallery channels and ran each operation inline,
so one slow backend operation held every operation behind it, model
operations included. In distributed mode the manager also visited the
nodes one at a time and waited for each up to the install timeout.

Backend operations now go through a scheduler that runs up to
max_concurrent_backend_operations of them at once. Operations start in
the order they arrive. Install, upgrade and delete of one backend share
a key and never overlap; an operation that waits for its backend does
not hold a slot, so independent operations pass it. Cancelling a queued
operation drops it at once. The limit is read on every scheduling step,
so a runtime change applies without a restart. With the default of 1 the
behaviour is the old single worker. Model operations get their own loop
and stay serial.

In distributed mode the manager sends one operation to its nodes in
parallel, up to the same limit, and keeps the result in node order. A
per (node, backend) lock keeps a live operation and the reconciler from
sending the same operation to a node together; the reconciler skips a
row that is locked and checks that the row still exists before it sends.
Timeouts are unchanged.

The download progress timers were plain package variables. They are
atomics now, because operations can run in parallel.

mudler-agentandEttore Di Giacinto c60a2e47d6 feat(backends): timestral.cpp forecast backend and /v1/forecast API (#12885)
* feat(grpc): add a Forecast RPC for time-series models

Add Forecast to the backend service with columnar request and response
messages: flat row-major arrays, NaN for missing values, and one message
per series so a caller can send series of different shapes in one call.
The response keeps the request order.

Wire the RPC through the server, client, embedded client, connection
evicting client, in-flight tracking client and the base backend, which
answers unimplemented. core/backend gains a Forecast helper that stamps
the model identity and records a trace, like the other single-purpose
RPCs.

* feat(config): add the forecast usecase

FLAG_FORECAST marks a model as a time-series forecaster. The timestral-cpp
backend declares it as its default usecase, so a config with that backend
needs no extra lines. The backend is also listed as a non-text backend, so
a forecast model is never offered as a chat model. It shows up in the
gallery filter and in the capability list.

* feat(api): add POST /v1/forecast

Take one or more numeric series and return quantile trajectories for the
next prediction_length steps. Targets are [variates][steps] or a flat
array for one variate; JSON null marks a missing value. Past and known
covariates and categorical codes are checked for length before the
backend sees them. Quantiles default to 0.1, 0.5 and 0.9 in the backend.

The route is gated by a new default-on forecast API feature. The endpoint
is listed in the swagger spec, the /api/instructions index, the UI model
filter and the capability symbols.

* feat(backends): add the timestral-cpp forecast backend

Wrap the timestral.cpp C ABI with purego, the way the other ggml
backends do: libtimestral is built from a pinned commit with ggml
embedded, and the Go binary loads it at start.

Forecast validates the counts against the array lengths, groups the
series by shape, makes one library call per group and puts the results
back in the order the caller sent them. Quantiles default to 0.1, 0.5
and 0.9, and a level the model does not have is refused with the list of
valid ones. A mutex guards the handle because the library is not
reentrant. Request size is bounded by two model options.

The unit specs use a fake library. The integration specs and a gRPC
spec run against the 5M F32 model that test.sh downloads and checks
against a fixed SHA-256.

The library entries were generated with backendcatalog. The images are
not published yet, so the release entries are unpinned until a

the library instead of a fixed number, so adding a backend does not
break it.

the CPU only.

The weights use Mistral's Modified MIT licence, which bars use by
companies above a monthly revenue threshold. The first paragraph after
the summary says so, the licence file is installed next to the weights,
and the revenue-restricted-license tag makes the entries filterable.

The memory each build needs has not been measured, so no size is set.

* feat(addons): generate and load a static carrier key set

A split deployment needs the owner and the frontends to share

GenerateCarrierKeys writes a CA certificate, an owner leaf and a

so nobody can issue a third leaf, and it refuses to overwrite any file.
LoadCarrierConfig reads only the files of one role and refuses key
files that group or other users can access.

The owner never forwards, but NewCarrier still requires a signing key,
so the owner config gets a throwaway key in memory instead of the

* feat(addons): add util addons-carrier-keys

An operator who runs the add-on owner and its frontends as separate
workloads needs a way to make the shared key set. The command wraps
GenerateCarrierKeys: --out names the directory and --owner-host, which
can repeat, sets the names the owner certificate is valid for. It prints
which files belong on the owner and which on the frontends.

* feat(addons): add the owner and frontend roles to local-ai run

Every local-ai run process is its own add-on owner, so a distributed
deployment cannot scale its frontends: replicas that share a data
volume fight over the owner lock.

--addons-role selects combined (today's behaviour, the default), owner
or frontend. The owner and frontend roles also take --addons-owner-address
and --addons-carrier-dir, and the owner takes --addons-owner-listen. They
use the fixed carrier identities and the key set from the carrier key
directory. The frontend role has no add-on root, so it never creates the
add-ons folder. A bad role setup stops startup with a message that names
the flag.

* feat(addons): keep the frontend role away from owner state

A frontend holds no add-on state, but it still wrote the library
sources file of the data path, which is the owner's file. The frontend
role now skips the library option and reads only the galleries named by
the flags, and logs a warning when it has no account database, because
its pins are then kept per frontend.

The add-on manager rejects a relative root even for a forwarding
frontend, so the frontend config names the absolute path where an owner
would keep its state. Nothing creates or opens it, and a spec checks
that the data path stays empty.

* test(addons): run the owner and frontends as separate applications

The split roles are only useful if an owner and its frontends work as
separate processes that share nothing but the carrier keys and the owner
address. A spec now builds them as separate Application values with
their own data paths and keys from GenerateCarrierKeys.

It covers a frontend that lists apps and reads add-on status through the
owner, two frontends on one key set, a frontend that starts while the
owner is down and answers unavailable, a second owner refused on the
same root, and an owner that restarts on the same root and address and
still serves the installed add-on to the same frontend.

An operator who runs several frontend replicas had no documented way to
stop each one from being its own add-on owner. The add-ons page now has
a section for the owner and frontend roles: one owner replica with its
own volume and a recreate-style rollout, a stable owner address, key
generation and per-role mounts, a Compose example, what a restart and an
owner outage look like, the models-path limit, and the frontend limits.
The singleton section names the roles and the distributed-state mode,
and the distributed mode page links to the new section.

* feat(addons): gate the addons feature in /api/features

One function, Application.AddonsFeature, decides whether the add-on
side is on. A combined or owner process answers true when add-ons are
enabled and the owner manager exists. A frontend answers true when the
owner answered the carrier's audience call within 2 s, and keeps that
answer for 10 s so /api/features does not dial the owner per request.

/api/features reports the result as "addons", and fine_tuning and
quantization take the same value, because both are add-ons. The
frontend cache is per-instance state.

* feat(addons): answer 503 on every add-on route when add-ons are off

With --addons-enabled=false the real add-on, fine-tuning and
quantization routes and services are not registered. One catch-all per
prefix answers the typed unavailable response of an absent owner, for
any path under it, so a client cannot tell which routes exist. The
response is the one the gateway already writes (gateway.WriteUnavailable
over typedError), not a second format.

With add-ons on, the same routes sit behind RequireAddonsFeature, which
reads Application.AddonsFeature, so a frontend that cannot reach the
owner gives the same answer. The per-user feature middleware still runs
after the gate. No endpoint is added, so the swagger, /api/instructions
and RouteFeatureRegistry surfaces do not change.

OwnerConfig.validate required an absolute root for every role, so a

NewCarrier required an Ed25519 signing key of every instance, so the

NewCarrier accepts an empty key when the instance is the owner and
still requires a whole key from a frontend, and a malformed key is
refused for both. LoadCarrierConfig no longer generates one. The owner
still verifies frontend signatures with frontend-sign.pub.

* Keep the owner address out of the add-on identity file

The owner address is runtime configuration, so storing it and comparing

A frontend must keep no owner state, but the library-source routes, the
ApplyLibraries call and the startup official-libraries step still opened
and wrote addons/sources.json in its data path.

Mark the frontend role in the add-on config, also when add-ons are off.
On a frontend, LibrarySources returns the unavailable error,
ApplyLibraries does nothing and the startup step skips the store. The
six /api/library/sources routes answer 503 with the body that the add-on

* feat(addons): serve library calls on the add-on owner

Add the carrier verbs a frontend needs to work on the library through
the owner: library-list, library-add, library-update, library-enable,
library-disable, library-remove, library-backend-resolve and
library-backend-releases. A call carries the operation in one
LibraryCall field of the wire request, so an old owner rejects it as an
invalid binding. Every verb but the three reads is a mutation, and the
reply is an envelope of data or a typed error, so a frontend gives the
status the owner's own routes give.

The owner serves them through gateway.LibraryAdmin, implemented in the
application on the same LocalAdmin as the owner's HTTP routes. It runs
the owner's administrator check before any store call.

Add two peer-authenticated reads that take no actor and leave the
audience reply unchanged: GET /addons/capabilities (protocol, calls and
the owner's OS and architecture) and GET /addons/library/snapshot (the
gallery-relevant source list and its version).

Split the backend install: Installer.Resolve is the owner's half
(resolve, pick the meta backend for the asker's capability, pin by
digest) and returns a Plan; the node that installs runs the collision
check and the gallery install itself. Move the source administration
behind library.Admin and add library.ReconcileInfos for a source list
read from the owner.

* feat(addons): forward library routes from a frontend to the owner

A frontend refused the library-source routes and did not serve the
backend library routes. Forward them instead, and keep the owner the
only writer of the sources.

The library-source routes work on library.Admin: the local store on a
combined or owner process, the carrier on a frontend. The frontend
checks the calling account (a legacy API key is refused with 401), and
the owner checks the administrator right again before any store call.
With add-ons off, a frontend answers these routes with a 503.

A frontend asks the owner for its source list every 60 seconds through
the peer-authenticated snapshot call and rebuilds its model and backend
gallery lists, and the official-libraries switch, only when the version
changed. If the owner does not answer, it keeps the last lists and marks
them stale. Changing official_libraries on a frontend is refused with
409.

The backend library install is split. The owner resolves the entry and
pins the image; the frontend runs the gallery install on its own node,
with its own size limit and strict mode. A frontend refuses library
calls to an owner that does not serve them, or that runs on another OS
or architecture.

* docs(addons): document library operations on a frontend

routes with what happens now: the library sources and the backend

60 seconds, official_libraries is set on the owner, and the owner and
the frontends must run on one OS and architecture.

Add specs for the split owner: a frontend lists sources through the
owner, a source added on a frontend reaches the owner and then the other
frontend after a refresh, a write with the owner down answers 503 with
the error envelope, official_libraries answers 409 on a frontend and a
change on the owner reaches the frontend's gallery lists, the lists are
kept and marked stale while the owner is down, a platform mismatch and a
legacy API key are refused, and a frontend installs a backend into its
own path from the owner's plan.

* feat(addons): check the shared models path with a probe

Exports write into the models path of the owner, and frontends load
models from their own path. A wrong mount fails silently: the export
succeeds and the model never appears.

The owner writes a probe file with a random nonce into its models path
at start. A frontend fetches the nonce over the carrier and checks at
start, then every 60 seconds, that the same file is visible at the same
absolute path. On a mismatch it logs an error, reports model_exports
false and blocks its export and import routes. The owner refuses an
export or import while its own probe is missing, and keeps running if
it cannot write the probe. An unreachable or older owner gives
"unknown" and leaves exports on.

* feat(addons): let frontends run the backend update check through the owner

In named-user mode a frontend has no user to act as, so the background
backend update check failed there. Add one read-only system call for
the release lookup. The owner accepts it only on the peer-authenticated
route from a pinned frontend, only for backend-releases, and without an
actor. Calls through /addons/forward cannot carry the mark, and every
user-facing call still goes through the administrator check.

library source routes stay out of the catalog: the assistant has no

hit the refusal of the export route. Add GET /api/fine-tuning/status and
GET /api/quantization/status. Each returns {"model_exports": bool}, from
the same check that drives the model_exports key of /api/features.

The routes sit behind the add-ons gate, so they answer 503 when add-ons
are off. They are listed in the swagger spec, the instructions registry,
the route-feature registry and the feature docs.

* feat(addons): let add-on pages keep the host modules they were written against

A page written for the web UI imports React, the router, i18next and a
few shared components. The add-on builder refuses a bundle that holds a
host file, so moving such a page into an add-on meant rewriting it.

Add a compat mode to the shared builder. It answers those imports from a
directory of stand-ins that read the SDK, bundles the dynamic import of
the page code into the one output file, and collects the style sheets the
page imports. A relative import that is not in the add-on's own source
resolves to the file at the same path under the compat directory.

Widen the SDK for these pages, without a version change: more host
components (spinner, modal, lightbox, model picker) and hooks (models,
resources, voice profiles, operations, MCP client), a style on icons,
the icon names the pages draw, sdk.navigation.openApp to open a page of
the app (only addresses under /app, and the way back as the only state)
and sdk.portal. The shell passes the query string to the page.

The stand-ins cover the router (the tab in the path, the model in the
query), the translator over the host locale files, the core API calls
through sdk.core.fetch, and byte copies of the pure helpers, with tests
that keep the copies equal to the originals.

* feat(addons): ship Studio and Talk as add-ons instead of built-in pages

Studio and Talk were compiled into the web bundle and always listed in
the Add-ons drawer. They are add-ons now, like Voice, Face, fine-tuning
and quantization: a person installs and removes them, the drawer lists
them only while they are installed, and they are packaged the same way.

Move the pages, their components, hooks and helpers into addons/studio
and addons/talk. Each has a manifest, a UI bundle, a release platform
matrix and a catalog template, and is built by the compat mode of the
shared builder. The core API stays where it is: the pages call it with
the signed-in person's session. The history keeps its browser storage
keys. The unit tests of the moved helpers move with them.

In the core, drop the two pages, the Create group of the sidebar (Chat
joins Home and Models in the old layout), the built-in catalog entries
(the catalog is empty) and the talk locale namespace. The old addresses
(/app/studio, /app/talk and the generator links) redirect to the add-on
pages, with the model as ?model=. The Home /studio command is offered
only while the Studio add-on is installed and opens it.

them. studio-addon.js holds that helper, and the Studio and Talk
fixtures call it.

Update the specs for the new addresses (/app/addons/studio/studio, the
model as ?model=), the session permission the add-on route needs, the
legacy redirects, the Home /studio command that appears only while the
add-on is installed, and the sidebar without a Create group.

Add specs for the add-ons themselves: every tab draws with no script
error, the shell titles the page once, the old addresses say so when the
add-on is not installed, a button of the page reaches a core page with
the way back, and the drawer lists both only after they are installed.

Add gallery/addons/index.yaml, a YAML index of the four first-party
add-ons (fine-tuning, quantization, voice, face) in the library format.
The entries come from addonpkg catalog over locally built linux/amd64
packages, so the digests pin those images.

On the first start, when the owner has no sources.json, register the
raw GitHub URL of that index on master as the "official" library and

and one drawer entry. Recognition, Library, Text to speech and From a
recording are tabs of that page, drawn with the same tab strip the
recognition page already used. The tab is the first path segment
(voice/library), as in the Studio add-on, and the form that adds a voice
is a view of the Library tab (voice/library/new).

* feat(addons): add a kind to library entries and read unknown kinds tolerantly

A library entry now has an optional kind: addon (the default when it is
absent), backend or model. Every index written before kinds existed stays
valid and its entries are add-ons.

A reader keeps the entries of the kinds it knows and skips the others
without reading their fields, so a newer kind never makes an older host
refuse the whole index. The refresh result and the library state report
how many entries were skipped and of which kinds, and the refresh logs a
warning. A kind that is not a plain kind name still makes the index
malformed. Search lists add-ons unless the caller asks for a kind, and
Resolve returns add-ons only, so an add-on install cannot be pointed at
a backend image.

A library policy may name the signer with an anchored identityRegex
instead of an exact identity, so builds from master and from tags both
verify. An add-on install refuses a policy that carries one.

* feat(backends): install a backend from a library entry

A library can now list backends. An entry of kind backend names the
image of the backend gallery by digest, and POST /backends/library/install
installs it on the local node. The gallery stays the source of truth and
its install path is the one used: the library resolves the entry, takes
the signature policy from the library, pins the image by digest and calls
the same install as the gallery. Installing a name that came from a
gallery, another library or by hand is refused and changes nothing.

The signature policy of a backend library names the signer with an
anchored identityRegex, so images signed by the merge workflow on master
and on tags both verify. A pattern that is not anchored is refused.

An install is bounded by a size limit per kind: add-ons keep 512 MiB and
a backend image defaults to 8 GiB, set with --addons-backend-max-bytes.
The limit reads the manifest after the signature check and before any
layer is fetched. The metadata of an installed backend records the
library it came from.

scripts/backends/cmd/backendcatalog renders entries from
backend/index.yaml and pins them against the registry. The pilot is the
CPU build of local-store, in gallery/backends/index.yaml. The library is
registered on the first start only with --addons-backend-library, which

each one as an add-on or a backend. A backend installs through the
backend route and not through the add-on lifecycle: the confirmation
says that the backend gallery is not changed and that a backend runs
native code, and a refusal of the host, such as a name installed from
another origin, is shown with its own reason. The details give the kind,
the alias and the signer pattern.

The library editor can name the signer with a pattern. Without this a
save would drop the pattern of a backend library. The Libraries tab
reports the entries a refresh skipped because their kind is not read.

route, the size limit of each kind, the pilot library and the command
that renders it. The backend page links to it.

* feat(mcp): install a backend from a library entry

The backend library route installs a backend from an add-on library
entry, and the admin REST surface and the MCP catalog must stay in step.
Add the install_library_backend tool with an in-process and an HTTP
client, the route map entry, the safety-rule listing and a skill recipe.

Listing library entries stays on the add-on routes, which the assistant
does not expose, so no list tool is added.

The add-on library and backend library strings existed only in English,

addons namespace to de, es, id, it, ko, pt-BR and zh-CN. The values are
the English text until a translation is contributed.

* feat(backends): report the steps of a library install as a job

A backend install from a library ran inside the request and showed
nothing until it ended. It is now a job of the gallery service, the
kind the backend gallery installs use. The request answers with the job
ID and GET /backends/jobs/{id} reports the step as the phase of the job:
resolving, verifying, size, fetching and writing, with the byte progress
of the fetch. A job that fails keeps the phase of the step that failed
and gives the reason. A second install of the same name is refused while
one runs.

The downloader and the gallery install report their stages through an
optional hook, so the steps are the real ones and not a guess. The
Browse tab lists the steps of the entry being installed, marks the one
that failed, and omits the signature step for a library that does not
require one.

The library installer also gets Updates and a route that lists the
installed library backends with a newer build in their library, for the
next change.

* feat(ui): mark library backends and offer their updates on the Backends page

A backend installed from a library now shows the library ID next to its
name and, in the detail, the library and the digest that metadata.json
pinned. Gallery backends look and behave as before, and the gallery
reinstall is not offered for a library backend, because the gallery does
not list it.

When the cached index of the library lists another build in the channel
of the installed version, the row says "Update available" and offers an
Update button. The button starts the same install as the Browse tab, and
the detail shows its steps. Nothing is upgraded on its own. The check
says nothing when the library no longer lists the installed version and
has several channels, instead of guessing one.

* fix(mcp): match the library installer to the progress type

* feat(gallery): add the model library entry shape and its reader

A model library entry is the shared library envelope (kind, id, name,
version, description, license, urls, tags, icon, channel, policy,
schemaVersion) plus a model body: url, backend, size, files,
configFile, overrides, variants and promptTemplates. The envelope lives
in the catalog package so the other kinds can move to it.

A gallery entry converts to a library entry and back to the same
gallery entry. Floats are written so they read back as floats, and an
empty variants list stays distinct from an absent one, because both
occur in the real index.

The reader is strict: unknown fields, duplicate ids, a second document
and a flow-style list are refused. An entry of another kind is skipped
and reported, as in the add-on reader. The gallery index stays the
default and is not changed.

* feat(gallery): render the model library from the model gallery

scripts/models/cmd/modelcatalog reads gallery/index.yaml with the same
structs the host reads it with, converts every entry to a library entry
and back, and fails if any entry does not come back equal. It writes
gallery/models/index.yaml and the golden files for the tests. The
output is deterministic, and the gallery is only read.

The golden files are a digest pair for every entry (the gallery entry
and the library entry made from it) and a readable gallery and library
pair for each kind of entry: plain, with variants, with an empty
variants list, with a config file, with a size, with a backend, with
floats in the overrides, without a url, without files and with a
multiline description.

All 2212 entries of the index round trip. The gallery struct does not
read a few keys (last_checked, parameters and four stray capitalised
keys); the host drops them when it loads the index, so the library does
not carry them, and the command reports them.

* feat(gallery): add --model-index-source to read the model library

--model-index-source selects the file the host reads the models of the
official gallery from: gallery (the default) or library. With library
the gallery named localai reads the model library, from
--model-library-url or the file in the repository, and keeps its
configured name and URL on every entry. A gallery the owner added keeps
its own index, and add-on and backend galleries never take this path. A
library that cannot be fetched or read is an error and not a fall back
to the gallery, so the setting is never silent.

The tests round trip every entry of the real gallery index, compare it
with the golden files, check the rendered library file reads and agrees
with itself, and cover the strict reader, the kinds it skips, prompt
templates, number types, empty lists and the setting.

* feat(backends): upgrade library backends with the auto-upgrade switch

The upgrade checker now installs the newer build of a library backend
when auto_upgrade_backends is on, on the same check that upgrades the
gallery backends. With the switch off nothing is installed and the
Update button stays manual. The switch is read on every check, so a
change in the runtime settings applies at the next one. There is no
second toggle.

The tests cover both states and a host without a library.

* feat(cli): add local-ai library to manage library sources

local-ai library has list, add, remove, enable and disable. It works on
the source store the server reads (addons/sources.json under the data
path), so it also works with the server stopped. A source has a kind
(addon, backend or model); the store records whether it is a shipped
default, and removing a default leaves a tombstone so it does not come
back at the next start.

The shipped model and backend gallery indexes are default sources next
to the official add-on library. Defaults are added at every start when
they have no record yet, and an existing file that holds no default is
left alone as before.

The --model-index-source and --model-library-url flags are removed: a
model library is added as a model source, and the gallery entry says it
is a library.

* feat(addons): let a source of your own win an entry over a default

When two enabled sources list the same entry (same kind and id), the
source the user added wins over a shipped default, and the default is
ignored for that entry. When two sources the user added list it, search
and resolve are refused with an error that names the entry and both
sources, and nothing is picked silently. Among shipped defaults nothing
changes.

The tests cover a user source over a default, a tie between two user
sources, a default ignored once a user source wins, and the case where
disabling a source ends the conflict.

* feat(cli): map the gallery flags to library sources at startup

--galleries and --backend-galleries keep loading the same JSON. At
startup each entry they name also becomes a source the user owns, of
kind model or backend, so local-ai library list shows it. The mapping is
additive: an entry whose kind and URL is already a source (a shipped
default, one added with the CLI, or one mapped at an earlier start) is
not added twice, and a derived id never collides with another source.

The sources then decide which galleries the server reads: a gallery
whose source is disabled or removed is left out, and a model library or
gallery added with local-ai library add is added. A list set by the flags
still replaces the shipped defaults. If the store cannot be opened, the
galleries stay as the flags set them. The autoload switches are not
touched.

* refactor(library): use id for every kind and seed the default libraries

The backend entries of the library used addonId while the model
entries use id. Release now has the field ID, written as id for every
kind. ReadIndex reads addonId as a legacy alias for one release, for
add-ons and backends, and refuses an entry that holds both names. The
backend index and the catalog generator write id.

The shipped libraries are default sources. The pilot backend library is
now on by default, like the official add-on library, and the model
library is a new default model source, official-models. The server
reads it next to the localai gallery. A source the user removed stays
removed, and a source the user adds is added to the defaults.

The model catalog header held a backtick that ended its raw string, so
the generator did not build. The header no longer has it.

* feat(library): choose the default model source by build

A build read both the localai gallery and the official-models library
by default, so every model was listed twice. Now a build reads one of
them. library.ModelSource names it: "library" or "gallery". The model
source that is not chosen is still shipped, as a disabled default, and
local-ai library enable turns it on.

The value is a Go variable set at link time with -ldflags, because the
same source tree makes both kinds of build and a constant would need a
commit to change. It is "library" in the source, so a build from
master, go build and go test read the library. Only the exact value
"gallery" selects the gallery, so a mistyped value cannot leave a build
without a model source.

The Makefile sets it from LOCALAI_MODEL_SOURCE. When that is not set, a
commit that carries a tag gets "gallery" and any other commit gets
"library". .goreleaser.yaml passes the same variable and defaults to
"gallery". The release workflow sets it to "library" on a tag, which is
the cutover.

A default source is seeded once, so a data directory that an earlier
build seeded keeps its enabled flags. Switch it with local-ai library
enable and disable.

Tests assert the master default, the tagged default before the cutover
and after it, and that a mistyped value reads the library. The model
library header now says that CI checks it and when a build reads it.

* ci(library): check the model library and cut over on tag

No workflow checked gallery/models/index.yaml, so it could go stale
when gallery/index.yaml changed. A new workflow, model-library.yml, runs
on pull requests and on master when the gallery, the library, the
generator or core/gallery change. It runs the generator tests and the
library shape tests (the file decodes, it has the library shape, every
real entry round trips), then renders the library again from
gallery/index.yaml and fails on any difference with git diff
--exit-code. The error message gives the command that fixes it.

release.yaml gets the cutover. On a tag, a step sets
LOCALAI_MODEL_SOURCE=library before GoReleaser runs, and
.goreleaser.yaml links it into the binary. Without that step a tagged
build reads the gallery. The step is the one place to remove when the
gallery is retired.

* feat(library): make the model library the source of the gallery

The library, gallery/models/index.yaml, was rendered from the gallery.
Now it is the source and models are edited there. modelcatalog reads
the library and writes gallery/index.yaml, a generated copy that stays
only so releases before the cutover keep working.

The gallery file is written in the shape the host reads: the same
field order, floats such as 1.0 keep their form, and an empty variants
list stays apart from an absent one. The command converts every
library entry to a gallery entry and back, loads its own output the way
the host does, and fails when an entry comes back different.

The gallery copy drops what the library cannot carry: last_checked,
parameters and four capitalised keys (Base Model, Context Length,
License, Training Data). The gallery struct has no field for any of
them, so the host ignored them on load. Every run lists these keys and
how often the file being replaced still had each. Loading the old and
the new gallery with the host structs gives equal entries for all
2212 models.

The tests that read the library and the golden files follow in the
next commit.

* ci(library): check the library and that the gallery is its copy

The model-library workflow assumed the gallery was the source. It now
checks the library file, the new source. The library decodes, every
entry has the library shape, every entry converts to a gallery entry
and back, and the gallery reader loads the generated gallery and sees
the same names, file uris and digests. The workflow then generates
gallery/index.yaml again and fails on any diff with git diff
--exit-code. The message says the file is generated, not to edit it by
hand, and gives the command that regenerates it.

The tests in core/gallery read the library file now. The round trip
runs library to gallery and back on all 2212 real entries, a new test
compares the checked-in gallery with the generated copy so go test finds
a hand edit too, and the golden digests and samples are written from
the library. The version of an entry is no longer compared with a digest
of its content, since an edit to the library does not change it.

The docs say the library is the source, the gallery file is a generated
copy for releases before the cutover, and edits go to the library. The
agent guide for adding models says the same.

* feat(library): add admin routes for library sources and an official libraries switch

The library sources of the add-on, backend and model kinds had a CLI
but no HTTP routes. Add them for administrators, on the same store and
the same functions as `local-ai library`, so the two cannot drift:

  GET    /api/library/sources
  POST   /api/library/sources
  POST   /api/library/sources/{id}/enable
  POST   /api/library/sources/{id}/disable
  DELETE /api/library/sources/{id}

The list carries kind, default, removed (a tombstone), suspended and the
conflict message of a source that clashes with another one. A change to
a model or backend source applies to the running server. A deleted
source drops its gallery by address; a removed default keeps its record.

Add the runtime setting official_libraries (default on), with the flag
--official-libraries. When it is off, every shipped default source of
the three kinds is suspended: it is not read, stays in the store marked
default, and comes back when the setting is on again. Sources the user
added are not affected.

* feat(ui): list library sources of all three kinds in the Libraries tab

The Libraries tab of the Add-ons page now lists the sources of the
add-on, backend and model kinds from the new library routes. It has a
kind filter with counts, a Default badge, the state of each source
(enabled, disabled, removed, or off while the official libraries are
off), turn on and off, a Restore button for a removed default, and the
conflict message next to a source that clashes. Adding a source takes a
kind and, for backends and models, an index format.

Settings gets the toggle "Use official libraries" for the
official_libraries setting.

Add unit tests for the list and the kind filter, and a Playwright spec
that runs on a fresh test server started with --library-sources (its own
config, port 8097): it lists the three kinds, adds a model source,
disables and removes a default, checks the conflict message and the
official libraries toggle.

* feat(library): extend the backend body to carry what the gallery carries

The backend library entry only held an image and its digest. The backend
gallery holds more that matters at install and in the UI, so the library
could not replace it. Add the missing fields to the backend kind and keep
the strict reader.

New fields, all refused on an add-on entry:

- mirrors: ordered fallback images of the same backend, each oci://.
  The install pins them with the digest of the artifact.
- capabilities: a map from a host capability to a backend id. An entry
  with capabilities and no artifact is a meta backend. It has no digest,
  os or arch, is listed for every platform, and installing it installs the
  backend its capability names, in the same library and channel.
- license, urls, tags: display metadata, bounded and checked as text.
- icon: an https URL. The add-on ui.icon stays a path in the package. The
  host never fetches the icon.
- mutable: the artifact is a moving tag, such as a development image. The
  entry has no digest. The install resolves the tag to a digest, verifies
  that image and records the digest it installed.
- schemaVersion: the envelope version. A higher one is refused.

The index bounds grow to 8 MiB and 4000 entries, because the backend
library lists every image for every platform. Release now holds lists, so
the add-on staging compares it with Equal instead of ==.

* feat(library): render the backend library from the whole backend gallery

Add the conversion between a gallery backend and its library entries in
core/gallery, and make scripts/backends/cmd/backendcatalog build the
library from the gallery and the gallery from the library.

The library now holds all 1093 gallery entries as 1088 backends, because
five names appear twice in the gallery with the same content and are
folded. That is 934 concrete backends and 154 meta backends, written as
1240 entries: a backend built for several platforms has one entry for
each, with the digest of that platform image.

- 539 release entries are pinned by the digest the registry serves for the
  platform.
- 543 development entries (master-* tags) keep their tag and are mutable.
  The install pins them.
- 4 release entries are not pinned, because the registry has no image for
  them: cpu-qdrant-store, metal-qdrant-store, cpu-gemxcpp and
  vulkan-gemxcpp. They are marked mutable and no digest is invented.
  Render them again with --repin once the images exist.

The generator can import a gallery once, pin the release images again, and
write the gallery file from the library without the network. Before it
writes it converts every backend to the library and back and fails if one
does not come back equal. A policy is no longer written on each entry,
because the host takes the policy of the library source.

* test(library): check that every backend gallery entry round trips

Prove that the backend library can replace the backend gallery. The golden
input is the real backend gallery from before the library became the
source: 1093 entries, kept under core/gallery/testdata/backend_library
with the pins the library holds and the digest of each generated entry.

TestBackendLibraryRoundTripsEveryRealGalleryEntry converts each entry to
library entries, writes them as an index, reads them as a host does,
validates them and converts them back. It asserts that all 1093 entries
come back equal on every field the gallery reader uses, and logs the
count. The five names that appear twice in the gallery have the same
content, so the twin is checked against the first one and folded.

The other tests check the library file in the repository: every entry
passes the host checks, every backend round trips, every meta backend
names concrete backends the library has, a development entry keeps its
master-* tag and has no digest, and the golden digests still match. Unit
tests cover each field, the fields the library cannot carry, which are
refused rather than dropped, and entries of one backend that disagree.

An entry with no artifact, digest, os or arch no longer writes them as
empty strings, so a meta backend and a mutable entry stay short.

* feat(library): make the backend library the source of the backend gallery

Flip the source the way the model library did. The backend library,
gallery/backends/index.yaml, is where backends are edited. The backend
gallery, backend/index.yaml, is now generated from it by
scripts/backends/cmd/backendcatalog and stays only so releases before the
cutover keep working. It no longer has anchors or hand-written order, and
it holds 1088 backends: the five names that were listed twice with the same
content are folded.

Which source a build reads is set at build time, like the model source:

- core/library.BackendSource is "library" or "gallery". Only the exact value
  "gallery" selects the gallery, so a mistyped value cannot leave a build
  with no backend source.
- A build from master reads the library. The Makefile reads the gallery for
  a commit that carries a tag (LOCALAI_BACKEND_SOURCE), and GoReleaser
  defaults to the gallery.
- A step in release.yaml sets LOCALAI_BACKEND_SOURCE=library, so a tagged
  build cuts over by itself.
- Both sources are shipped and one is enabled. With
  --addons-backend-library=false every build reads the gallery.

The server hands the shipped backend library to the gallery reader as a
library, so the Backends page lists it and installs from it the way it did
from the gallery. A backend library the user adds stays with the add-on
catalog. The shipped library is now a backend source, not an add-on one.

The new workflow backend-library.yml runs the tests, regenerates
backend/index.yaml and fails on a diff. It never reads the registry.
backendcatalog --add merges backends written in the gallery shape into the
library, so adding a backend does not mean writing platform entries by
hand; the agent guide says so.

A hardening switch for deployments that must run exactly the backend set they

backends — HTTP routes answer 403 up front, and a model whose backend is
missing is refused before any download: 409 on the API, an error on preload
and import. Whether a backend is present is asked of the execution target:
the local backend directory on a single node, the workers' listings on a
distributed frontend, which installs nothing itself. Backends already
present, including system-path ones, keep working.

* feat(addons): run the add-on owner in the normal binary

The owner was only enabled when an embedding host set the add-on config,
so a normal run answered every add-on request as unavailable.

Add --addons-enabled (default true) and --addons-ownership-mode
(default named-user, or local-owner; anything else stops startup).
The node is its own owner: state lives under the data path, and the
carrier uses loopback keys made at each start and kept in memory.
--addons-enabled=false turns the owner off completely.

Named-user mode needs the account database. With authentication off
the owner stays off and a warning says how to use local-owner.

The single-node loopback transport took a new ephemeral port at each

Choose the port once, keep it in the add-on state root (loopback-port,
mode 0600) and reuse it. If the port is taken at a later start, stop
with an error that names the port and --addons-enabled=false, because
another port would break the identity check. The keys and certificate

* feat(addons): let add-on pages keep the host modules they were written against

A page written for the web UI imports React, the router, i18next and a
few shared components. The add-on builder refuses a bundle that holds a
host file, so moving such a page into an add-on meant rewriting it.

Add a compat mode to the shared builder. It answers those imports from a
directory of stand-ins that read the SDK, bundles the dynamic import of
the page code into the one output file, and collects the style sheets the
page imports. A relative import that is not in the add-on's own source
resolves to the file at the same path under the compat directory.

Widen the SDK for these pages, without a version change: more host
components (spinner, modal, lightbox, model picker) and hooks (models,
resources, voice profiles, operations, MCP client), a style on icons,
the icon names the pages draw, sdk.navigation.openApp to open a page of
the app (only addresses under /app, and the way back as the only state)
and sdk.portal. The shell passes the query string to the page.

The stand-ins cover the router (the tab in the path, the model in the
query), the translator over the host locale files, the core API calls
through sdk.core.fetch, and byte copies of the pure helpers, with tests
that keep the copies equal to the originals.

* feat(addons): ship Studio and Talk as add-ons instead of built-in pages

Studio and Talk were compiled into the web bundle and always listed in
the Add-ons drawer. They are add-ons now, like Voice, Face, fine-tuning
and quantization: a person installs and removes them, the drawer lists
them only while they are installed, and they are packaged the same way.

Move the pages, their components, hooks and helpers into addons/studio
and addons/talk. Each has a manifest, a UI bundle, a release platform
matrix and a catalog template, and is built by the compat mode of the
shared builder. The core API stays where it is: the pages call it with
the signed-in person's session. The history keeps its browser storage
keys. The unit tests of the moved helpers move with them.

In the core, drop the two pages, the Create group of the sidebar (Chat
joins Home and Models in the old layout), the built-in catalog entries
(the catalog is empty) and the talk locale namespace. The old addresses
(/app/studio, /app/talk and the generator links) redirect to the add-on
pages, with the model as ?model=. The Home /studio command is offered
only while the Studio add-on is installed and opens it.

The release workflow and its tests now list seven add-ons.

* test(ui): run the Studio and Talk specs against the add-on bundles

The pages are add-ons now, so a spec that draws one installs the real
built bundle first: the apps list names it and its module and style
sheet are served from the build output, the way the add-on owner serves
them. studio-addon.js holds that helper, and the Studio and Talk
fixtures call it.

Update the specs for the new addresses (/app/addons/studio/studio, the
model as ?model=), the session permission the add-on route needs, the
legacy redirects, the Home /studio command that appears only while the
add-on is installed, and the sidebar without a Create group.

Add specs for the add-ons themselves: every tab draws with no script
error, the shell titles the page once, the old addresses say so when the
add-on is not installed, a button of the page reaches a core page with
the way back, and the drawer lists both only after they are installed.

media query, so they applied at every width. They now sit in a
max-width 720px query, and the reduced-motion rule in its own query, as in
the core sheet.

* feat(addons): add a kind to library entries and read unknown kinds tolerantly

A library entry now has an optional kind: addon (the default when it is
absent), backend or model. Every index written before kinds existed stays
valid and its entries are add-ons.

A reader keeps the entries of the kinds it knows and skips the others
without reading their fields, so a newer kind never makes an older host
refuse the whole index. The refresh result and the library state report
how many entries were skipped and of which kinds, and the refresh logs a
warning. A kind that is not a plain kind name still makes the index
malformed. Search lists add-ons unless the caller asks for a kind, and
Resolve returns add-ons only, so an add-on install cannot be pointed at
a backend image.

A library policy may name the signer with an anchored identityRegex
instead of an exact identity, so builds from master and from tags both
verify. An add-on install refuses a policy that carries one.

* feat(backends): install a backend from a library entry

A library can now list backends. An entry of kind backend names the
image of the backend gallery by digest, and POST /backends/library/install
installs it on the local node. The gallery stays the source of truth and
its install path is the one used: the library resolves the entry, takes
the signature policy from the library, pins the image by digest and calls
the same install as the gallery. Installing a name that came from a
gallery, another library or by hand is refused and changes nothing.

The signature policy of a backend library names the signer with an
anchored identityRegex, so images signed by the merge workflow on master
and on tags both verify. A pattern that is not anchored is refused.

An install is bounded by a size limit per kind: add-ons keep 512 MiB and
a backend image defaults to 8 GiB, set with --addons-backend-max-bytes.
The limit reads the manifest after the signature check and before any
layer is fetched. The metadata of an installed backend records the
library it came from.

scripts/backends/cmd/backendcatalog renders entries from
backend/index.yaml and pins them against the registry. The pilot is the
CPU build of local-store, in gallery/backends/index.yaml. The library is
registered on the first start only with --addons-backend-library, which
is off by default.

* feat(ui): show the kind of library entries and install backends from them

The Browse tab lists the entries of every kind this host reads and marks
each one as an add-on or a backend. A backend installs through the
backend route and not through the add-on lifecycle: the confirmation
says that the backend gallery is not changed and that a backend runs
native code, and a refusal of the host, such as a name installed from
another origin, is shown with its own reason. The details give the kind,
the alias and the signer pattern.

The library editor can name the signer with a pattern. Without this a
save would drop the pattern of a backend library. The Libraries tab
reports the entries a refresh skipped because their kind is not read.

in the style of the MCP dropdown. It lists each running add-on that ships
tools with a switch, and a badge shows how many are on.

The chat keeps the ids that are on (addonToolIds) next to the older
boolean, and both are saved with the chat. A chat that has only the boolean
means every add-on. The request sends addon_tools alone when every add-on is
on, and adds addon_tool_ids when only some are. /addons turns all on or all
off and uses the same state.

narrows that to some add-ons. The list counts only with the opt-in, and a
list that names nothing offers no tool rather than all of them.

The executor drops the tools of add-ons that are not listed and refuses a
call to one as an unknown tool, so a model cannot reach a tool the person

* feat(addons): upgrade add-ons on their own when the setting is on

A new auto_upgrade_addons setting (flag LOCALAI_AUTO_UPGRADE_ADDONS,
default off) lets the owner upgrade an installed add-on when its library
lists a newer version. It follows the backend setting: a startup flag, a
runtime setting, and the same schedule as the backend update check (a
first pass shortly after start, then every six hours).

Each pass fetches the library of every installed add-on, and for each
available update builds the same pinned upgrade command an administrator
sends and runs it through the same lifecycle path. The channel rules, the
signer identity, the digest checks, the SDK compatibility check and the
backup before the upgrade all apply unchanged. The only difference is the
gate: the owner acts on its own setting, so no administrator is asked.
A refused or failed upgrade changes nothing and is logged; a candidate
that failed is not retried until the library lists another digest.

With the setting off, nothing runs and upgrades stay manual.

nothing changes, and a change of the setting at run time takes effect on
the next pass. The manager specs show the upgrade goes through the same
pinned path as the manual one, and that a corrupted package, a failed
signature policy, an incompatible release, a missing update checker and
a caller who is not an administrator each leave the installed version in
place. The new specs are added to the lifecycle case inventory.

Stefan Walcz b56b903c92 feat(config): let model aliases carry an opt-in profile block (system prompt, MCP, client tools) (#12661)
* feat(config): let model aliases carry an opt-in profile block

An alias can now act as a profile of its target through an explicit
`profile:` block carrying system_prompt, mcp (remote/stdio servers, plus
the new mcp.auto) and the new client_tools. ResolveAlias applies only
that block on top of a copy of the target, while Name, Model, Backend
and the persisted revision stay the target's. The loader key is
therefore unchanged and every profile runs on the target's backend
process; today a persona needs a separate model config, which loads the
weights a second time.

The block is opt-in so existing aliases never change: top-level fields
on an alias stay ignored, and an alias without a profile block resolves
to exactly the target. A profile block on a non-alias config is
rejected.

A profile with its own MCP servers caches its sessions under the alias
name (MCPSessionKey), because the cache slot keyed on the target's name
is invalidated whenever its config hash changes and two server sets
would tear each other's sessions down.

mcp.auto enables all configured servers on /v1/chat/completions when the
request does not name any in metadata.mcp_servers, which plain OpenAI
clients cannot send. client_tools: drop discards client tools and
tool_choice before the request is merged (chat completions, responses,
Anthropic messages), so only the model's own MCP tools are offered.
Both keys work on any model and inside an alias's profile block.

* fix(openai): only auto-enable model MCP when MCP is enabled and permitted

mcp.auto turns a plain /v1/chat/completions request into a server-side
MCP request. It now applies the same controls as the dedicated MCP
routes before any server is selected: the instance switch
(LOCALAI_DISABLE_MCP) and, with auth on, the caller's "mcp" feature,
checked with auth.HasFeatureAccess against the auth database that the
chat route now passes to ChatEndpoint.

A denied request is answered as a plain chat, without contacting a
server or adding tools, rather than rejected: the client did not ask
for MCP, it only reached a model that offers it.

Endpoint specs drive ChatEndpoint against a counting MCP fixture server:
MCP disabled and a user with chat but without mcp see no tools and no
connection; MCP enabled and a user with mcp get the fixture tool. The
user specs need the auth build tag (SQLite auth database).

* fix(mcp): resolve profile aliases in the MCP discovery endpoints

GET /v1/mcp/servers/:model, /v1/mcp/prompts/:model and
/v1/mcp/resources/:model looked the model up with GetModelConfig, which
returns the alias stub. A profile alias carries its servers in its
profile block, so the stub has none of its own and the endpoints
reported an empty list for an alias whose chat requests do use tools.

Resolve the alias the way the request middleware does before reading the
MCP config, and open the sessions under MCPSessionKey so discovery shares
the profile's session cache slot instead of tearing down the target's.

* feat(config): opt-in evidence check for profile aliases

A profile with server-side MCP tools (profile.mcp, mcp.auto) runs its
tools on the server and returns only the answer text. On the next turn
the client sends the history back without those tool calls and results,
and the model then tends to skip the tool and answer from nothing. In a
measurement on a follow-up question, 0 of 12 turns called the tool and
the answers carried invented numbers (e.g. "0" where the true value was
9); with the tool trail kept in the history the tool was called 12 of
12 times. A prompt instruction does not reliably prevent this, so the
check sits at the output.

New profile keys:

  profile:
    evidence_check:
      numbers: true   # enables the check
      note: "..."     # optional, defaults to an English note

Rule, per request and stateless: when the check is on, no MCP tool call
succeeded on the server during this request (a call that returned an
error delivers no evidence and does not count), and the final answer contains a
number (\b\d+([.,]\d+)?\b) that occurs in none of the request's input
(the profile's system prompt and every message as received, before
compression), the note is appended after a blank line. "3,5" and "3.5"
count as the same number. In a streamed response the note is one extra
content delta before the finish chunk. Choices that hand tool calls to
the client are not checked. The setting is only read from a profile
block, so plain models and aliases behave as before; a note without
numbers: true is rejected at validation.

Tests (Ginkgo): the number rule (invented number, number from the input,
no numbers, comma/dot decimals, system prompt as evidence, tool ran),
the overlay into the resolved config with plain alias, target and a
top-level key as counter-checks, validation, and ChatEndpoint specs on a
stubbed backend for both paths: note on an invented number, none for a
number from the request, none for a profile without the check, none
after a successful MCP tool call against an in-process MCP server, and
the note again after a failed tool call (arguments that are not JSON).

mudler-agentandEttore Di Giacinto dce91ba7aa fix(backends): prefer installed development builds (#12782)
* fix(ci): capture and surface ginkgo errors in run-coverage.sh

The coverage script ran ginkgo per test root with `|| fail=1`, which
swallowed the exit code. Combined with `make --output-sync=target`,
which buffers all output and flushes at the end, the actual ginkgo
error was invisible in interleaved CI logs. Every test suite passed
but the script still exited 1, and the error message was buried in
22 000 lines of buffered output.

Each ginkgo invocation now captures combined stdout+stderr to a
per-root log file. On failure the last 80 lines are printed to
stderr so the error is visible in the CI log. On success the log is
replayed to stdout so test output remains visible.

The build flags (--tags, --coverpkg) are quoted correctly so values
containing spaces (e.g. --tags="debug auth") are preserved through
eval.

* fix(ci): create output dir before writing ginkgo logs

The previous commit added per-root log files but forgot to create
the output directory before the first ginkgo invocation. On CI the
coverage/ dir did not exist yet, so the shell redirect to
cover-pkg.out.log failed with "No such file or directory" before
ginkgo even ran.

* test(core/http): add canvas preview route to auth coverage allowlist

Commit 9ad78381d8 added GET /api/canvas/preview/:id as a public route
(no auth — the random id is the capability, an iframe cannot send API
key headers) but did not add it to expectedPublicRoutes in the route
auth coverage test. The test flagged the route as an anonymous-access
leak, failing the entire ./core ginkgo suite on every CI run since.

The POST /api/canvas/preview endpoint is auth-gated (returns 401 to
anonymous requests) and is intentionally absent from the allowlist.

Stefan Walcz f4505dbb5d feat(pii): optionally block content the detectors cannot inspect (#12755)
The PII middleware scans the text of every message, but images, audio,
video and files pass to the backend unchecked. For an egress policy
("nothing sensitive leaves the box") that is a hole: a photographed
invoice or an attached PDF reaches a cloud-proxy model without any check.

Add pii.block_unscanned_media. While PII is enabled for a model and the
option is set, a request that carries such content is rejected with the
usual 400 pii_blocked response and an audit event with pattern
__unscanned_media__, before any detector runs. Adapters report the
kinds of unscanned content through a new optional Adapter.Unscanned:
OpenAI chat (non-text content blocks), Anthropic messages (image and
document blocks; tool blocks stay allowed) and Ollama chat (images).

Off by default, so existing configurations behave as before.

mudler-agentandEttore Di Giacinto c7ce0c602c fix: stop listing the models directory on request paths and cache GGUF header reads (#12683)
* fix(http): stop listing the models directory on embeddings and bearer requests

Every embeddings request read the whole models directory before the body
was parsed, even when the body named its model. On a network-backed
models directory this cost seconds per request.

Embeddings now binds the body first and looks up a default model only
when the body has none, like chat. The pre-bind default lookup and the
gpt-4o constant default are gone from that route.

The first-available default lookup skips the directory when the filter
cannot accept an unconfigured file. Every usecase filter rejects files
without a config, so the scan never added results for them. Match-all,
nil and name filters keep the scan.

The bearer token check is now an exact test: a configured name, or one
stat of that name in the models directory. The value is a literal, not a
regular expression, and a name that is not a local relative path never
matches a file.

Assisted-by: Claude Code:claude-haiku-5-5

* perf(config): cache GGUF header reads for model defaults

Model defaults re-parsed the GGUF header on every SetDefaults call, which
runs per request and at startup reload. Put a bounded LRU in front of the
parser, keyed by absolute path and validated by size and modification
time. The cached value is a snapshot of the fields the defaults use, not
the parser output.

A changed size or mtime is a miss. Missing files and parse errors are not
cached, so the existing fallback is unchanged. LOCALAI_DISABLE_GUESSING,
the empty-path guard, the alias early return, the panic recovery and the
context-size default are all kept in front of the cache.

* test(http): cover listing-free default lookup on every usecase route

Assisted-by: Claude Code:claude-haiku-5-5

* feat(config): persist the GGUF header cache per instance

The header cache kept parsed GGUF results only in memory, so every restart
parsed each model file again before its defaults were known. Write the cache
to a per-instance file in the data path and load it at startup. A restarted
frontend with a fixed instance ID starts warm.

The file is versioned and records the estimator inputs (gguf-parser version,
candidate contexts, auto context size, offload count). A mismatch on any of
them makes the file ignored. Each entry keeps path, size and mtime, so a
changed model file is a miss on load. Writes run on one background saver,
debounced, through a temp file and rename. The entry bound applies to the
file as well. Without a data path the cache stays in memory only.

Documented as a per-instance exception in the model configuration docs.

* docs(embeddings): document model selection and the no-model error

Assisted-by: Claude Code:claude-haiku-5-5

* refactor(config): split the header cache into a generic cache

The GGUF header cache mixed two things: the mechanics (bounded LRU keyed
by path and identity, per-instance file, debounced atomic save, tolerant
load) and the GGUF fields. Move the mechanics into headerCache[S], driven
by a headerCacheSpec[S] that names the file prefix, schema, fingerprint,
parser and the snapshot encode/decode pair. The GGUF cache becomes one
instance of it.

File names, the identity check, LRU size, debounce, atomic write and the
corruption handling are unchanged. The on-disk JSON keeps the "estimator"
key so existing files still load.

Assisted-by: Claude Code:claude-haiku-5-5

* feat(config): share one GGUF header cache file between frontends

Every frontend used to write its own header cache file, named after its
instance ID, so a header read by one frontend was never reused by another.
The cache now uses one file, header-cache.json, in the data path, for all
frontends and for standalone mode. The instance ID no longer changes the
file name.

Frontends share the file in three ways. A save first merges the file's
entries in, so one frontend's write does not drop another's entries. A
miss reloads the file when its modification time has changed, and a hit
never reads it. Writes go to a temp file that is renamed into place, so a
reader never sees a partial file.

Two frontends saving at the same moment can still drop each other's last
entries. That costs one re-parse, never a wrong value, because every
entry is checked against its model file before use.

The shared file is valid only when every frontend mounts the same data
volume. The distributed-mode and model-configuration docs state this mode
and its volume limit.

The mirror of extend_to_next_word. A name model often tags the surname with
high confidence and scores the first name in front of it below min_score,
so "Gast Greta Waldmeister" became "Gast Greta [REDACTED:ner:LASTNAME]".

extend_to_previous_word lists entity groups whose accepted detections also
cover the word directly before them on the same line. The preceding word
must consist of letters (plus '-' and the apostrophe): a word with digits -
an amount, a date, a room number - is never taken, nor is a protected term,
and the search never crosses a line break.

Stefan Walcz e16b9d04cc feat(pii): protected terms that pass the NER filter unchanged
A name model reads many business names as surnames. Measured with
privacy-filter-multilingual on 24 synthetic German receipts and
invoices: the supplier name ("Hotel Seeblick", "Café Lindenhof", ...)
was masked as LASTNAME (0.78-0.98) or FIRSTNAME in 9 of 12 receipts
that carried one. The supplier is exactly what the upstream model needs
to categorise a receipt, and no score floor helps at those confidences.

pii_detection.protected_terms (inline) and
pii_detection.protected_terms_files (files inside the models path, one
term per line, '#' comments, re-read when size or mtime change) list
values that must pass unchanged. Each whole-word, case-insensitive
occurrence is replaced by a neutral placeholder before the detector
runs; every detection is mapped back onto the original text with the
placeholder parts cut out, so a protected term is never masked or
blocked, the detector never sees it as context, and event offsets keep
addressing the original text. A word extension (extend_to_next_word)
is dropped rather than run into a protected term.

Terms shorter than three characters are ignored. A missing or
unreadable file is logged and skipped: fewer protected terms means more
masking, never less. Paths are verified to stay inside the models path.

Opt-in, empty by default. Covered by Ginkgo specs in
core/services/routing/pii/protected_test.go (detector-visible text,
exact restoration, straddling detections, whole-word/case/line-wrap
matching, the segment path, file loading and reload), a YAML round-trip
spec, registry entries and the middleware/model-configuration docs.

Stefan Walcz beaeb05e52 feat(mcp): support OAuth2 client_credentials for remote MCP servers
Remote MCP servers could only be authenticated with a static bearer
token. Deployments that put their MCP servers behind an OIDC provider
(authentik, Keycloak, Entra ID, ...) issue short-lived service tokens
instead, so LocalAI had to be given a long-lived key or could not
connect at all.

A remote server entry now accepts an optional "oauth2" block
(token_url, client_id/client_id_env, client_secret/client_secret_env,
scopes, endpoint_params). The token is fetched with the
client_credentials grant by an http.RoundTripper installed on the MCP
client's HTTP client, so streamable HTTP and SSE transports both use it.
The token is cached and refreshed at half of its lifetime; if a refresh
fails the current token is kept until 30s before expiry, after which
requests fail with an error instead of going out unauthenticated.

"token" and "oauth2" are mutually exclusive and inconsistent blocks are
rejected when the model config is loaded. Static tokens behave as
before. MCPRemoteServer now implements fmt.Stringer so the existing
debug logs that print whole server entries no longer write the token
or client secret in clear text.

Stefan Walcz 9b13408c94 feat(pii): extend a detection over the next word (extend_to_next_word)
Address models tend to tag a postal code with high confidence but miss
or under-score the town right after it. Measured with
privacy-filter-multilingual on 24 synthetic German invoices: the postal
code was masked every time, while the town after it stayed in the clear
in 6 of 18 cases (4 not detected at all, 2 tagged CITY at 0.43/0.47,
below the configured floor). Masking the code alone leaves the pair half
redacted: "[REDACTED:ner:ZIPCODE] Ludwigshafen".

pii_detection.extend_to_next_word lists entity groups whose accepted
detections also cover the word that directly follows them on the same
line, with the same action and group. Horizontal whitespace is skipped,
a line break ends the search, and nothing is extended when no word
follows, so a hit never grows over bare whitespace or onto the next
line (or across the segment separator on the multi-message path).

The option is opt-in and empty by default; existing detector configs
behave exactly as before. Covered by Ginkgo specs in

mudler-agentandEttore Di Giacinto 895d50385f fix(distributed): converge model configs across frontends (#12558)
* fix(galleryop): announce model changes before the preload

After a gallery install or delete, the replica that ran it replaced its
config loader, then preloaded every installed model, and only then
published the models invalidation. The preload does remote lookups and
checksums for each model, so on a large models directory peers learned
about the change minutes after the originator listed it. When the
preload failed or the operation was cancelled, the event was never sent.

Publish the invalidation, and apply the delete lifecycle, as soon as
the loader holds the new set. The preload still runs afterwards with
its own error handling. Its failure is reported on the operation, but
it no longer rolls back a deletion that peers have already applied.

Assisted-by: Claude Code:claude-opus-5-5
Signed-off-by: Ettore Di Giacinto <mudler@localai.io>

* fix(distributed): resync model configs from the models directory

Frontends refresh their model configs only when a models invalidation
arrives on NATS. NATS keeps no history, so a frontend that is
disconnected when the message is published never applies the change.
It keeps serving the old config, for example an alias that points at
the previous model, until some later change happens to touch it.

Each frontend now reruns the peer reconcile against the shared models
directory after every NATS reconnect, and every
--model-config-resync-interval (default 30s) when a config file
changed. The pass names no model, so only models whose file changed
get a revision transition, and an unchanged directory costs one read
of the config files.

The reconcile replaced the whole loader with a parse of the models
directory, which dropped models loaded with --config-file and
published a deletion revision for them. Configs defined outside the
directory are now kept, both there and after a gallery install.

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

* fix(nodes): stop stale frontends from retargeting alias rules

A scheduling rule keyed by an alias derives its target from the alias
mapping of the frontend that reads it. Every frontend keeps its own
copy of the model configs, so after an alias is repointed a frontend
that has not reloaded it still resolves the old target. Two frontends
then rewrote the rule's stored target_model against each other on
alternate reconciler ticks, and the outdated one scaled up the model
the alias used to point at.

The registry already records the accepted config revision of each
model. A frontend now derives a rule's target from its own alias
mapping only when its config revision for the rule's name matches
that record. Otherwise it keeps the stored target_model: it neither
writes the column nor reconciles replicas of the old target. The check
reads the database only for a rule whose stored and derived targets
differ. With no accepted revision on record, the old behaviour stays.

Ettore Di Giacinto fa25493c9e feat(config): let parakeet-cpp declare the speaker_recognition usecase
parakeet-cpp now implements VoiceEmbed and VoiceVerify, so list them in
its backend capabilities together with the speaker_recognition usecase.
The usecase is not guessed, because most parakeet models have no
speaker encoder: a bundle declares it in known_usecases, which is
enough for /v1/voice/* and for voice_recognition.model.

Add a realtime pipeline test where one bundle model names the vad,
transcription, sound_detection and voice_recognition stages and the
gate resolves the speaker through the backend's VoiceEmbed.

Broadcaster is the fan-out half of MessagingClient. The NATS client and

wildcard other than a whole single token, and FakeBus shares MatchSubject
instead of its own copy. FakeBus Unsubscribe now removes its own
subscription instead of the first one with the same subject.

A shared conformance suite in messagingtest runs against both carriers.

openresponses/store.go, openresponses/sync.go, syncstate/syncstate.go,
finetune/service.go, quantization/service.go and
failover/distsync/distsync.go. SubscribeJSON now takes a Broadcaster
because it only calls Subscribe, which lets the narrowed consumers use it.

Stayed wide: worker/supervisor.go, because its client field also serves
the SubscribeReply handlers in worker/lifecycle.go. The request/reply,
queue and wiring files (nodes/unloader.go, nodes/file_stager_s3.go,
jobs/dispatcher.go, agents/dispatcher.go, agents/events.go,

The messaging client now refuses a subject whose root no carrier serves.
An agent worker started with a custom LOCALAI_AGENT_SUBJECT such as
tenant-a.agent.execute used to start and then wait on a subject the
frontend never publishes to. After the subject rules landed it exited
at subscribe time with an error that did not name the setting.

Behaviour change: the worker now checks LOCALAI_AGENT_SUBJECT before it
registers or connects, and exits with an error that names the variable
and says to use a served subject under the agent root, for example
agent.execute. The served roots are not widened: a custom root was
never delivered by the frontend, and a wider set would reopen the
drift the subject rules exist to close. The flag help and the agent

Three callers react to ErrNoRoute and had no spec: the reconciler's
upgrade drain falls back to the legacy forced install, the reconciler
marks the node unhealthy when a pending op has no route, and the
backend-op fan-out marks the node unhealthy. Each spec drives the real
caller with a scripted no-responders reply and reads the result from
the registry or the recorded requests.

A fourth spec pins the other side: a pending op that times out leaves
the node healthy and only counts the attempt, so mapping timeouts onto
ErrNoRoute would fail here.

Add specs that call Publish, Request, Subscribe, QueueSubscribe,
SubscribeReply and QueueSubscribeReply on a client with no connection.
Each call must return ErrUnservedSubject for bogus.thing and
ErrUnsupportedWildcard for jobs.>. This proves that the subject check
runs before the connection is used, and needs no server.

The NATS conformance suite is the only check that runs the subject rules
against a real carrier. Before this change it skipped without output
when Docker was missing. Now it fails when CI is set, so a Linux runner
without Docker cannot hide it. It still skips on local runs and on macOS
CI, which has no Docker.

The seams note said MarkUnhealthy was the only state change allowed
on ErrNoRoute. A pending backend op still records the failed attempt,
counts toward the reconciler's retry limit and is dead-lettered after
the maximum attempts. The note now says that MarkUnhealthy is the only
change to the node's own state, and that the per-op accounting is not
a verdict about the node.

The note also documents that the NATS conformance run fails under CI
when Docker is missing. The distributed-seams row moves next to the
distributed-state row in the topics table. The liveness ping spec
header now says no route is a reason to skip the worker, not proof
that the worker is gone.

stopped listening on jobs.*.cancel; the NATS permissions and conformance
suite spell the subject out, so nothing reads the constant.

decodeBackendStopRequest returned a stopAll flag that production dropped
and only a test read. decodeBackendStop is now the single decoder with the
same semantics: an empty body is stop-all, an empty Backend is stop-all,
malformed JSON is an error. stopBackends still derives stop-all from
Backend, so no reply changes.

* fix(messaging): keep an explicitly empty agent queue a plain subscription

Before the work queue seam the agent worker passed LOCALAI_AGENT_QUEUE
straight to QueueSubscribe, so an explicitly empty value made a plain
subscription and every agent worker ran every agent run.
WithAgentRunRoute replaced an empty queue with agent-workers, which
silently changed that.

Keep the queue as given once the option is applied. An empty subject still
falls back to agent.execute, since it never had a meaning of its own. The
flag default stays agent-workers, so only an explicitly empty value
reaches this.

second carrier notes to the developer note: the reconciler has no
ClientFactory option, the logs proxy honours HTTP_PROXY, verbs one carrier
serves need an opt-out, terminal replies come from the result event, and
agent runs publish through the NATS-bound EventBridge, which is not an
additive change.

2fa36e7147 feat(parakeet-cpp): speaker diarization, sound detection and live scene events (#12335)
* feat(parakeet-cpp): load diarization and CED models and companions

Repin PARAKEET_VERSION to parakeet.cpp PR #75's head, which adds
parakeet_capi_model_kind (ABI v8). Bind the new diarization, sound
event and combined scene stream C symbols through the same
purego.Dlsym probe pattern already used for the batched JSON entry
point, so the backend still loads against an older libparakeet.so.

Load now classifies the loaded GGUF by role (ASR, diarization or
sound) via parakeet_capi_model_kind and can load up to two companion
models from Options[] (asr_model:, diarization_model:, sound_model:,
paths resolved against opts.ModelPath), verifying each companion's
kind and freeing every context opened so far on any failure. Free
releases the primary and every companion. AudioTranscription now
names the loaded role when it is not ASR instead of a generic model
not loaded error. The dynamic batcher starts only when an ASR context
ends up loaded, primary or companion.

This is groundwork only: the Diarize and SoundDetection RPCs and the
live scene stream that actually use these new roles land in later
commits.

Zero all four alongside the CppFree calls.

* feat(parakeet-cpp): add speaker diarization

Implement the Diarize RPC for the parakeet-cpp Go backend, wired to
Nemotron-3-Diarization through libparakeet.so's diarization C-API.

Plain diarization uses parakeet_capi_diarize_pcm; when include_text is
set and an ASR companion is loaded, parakeet_capi_transcribe_and_
diarize_json fills each segment's text instead. Speaker labels are the
decimal index, or "unknown" for -1 (no diarized speaker overlaps).
min_duration_off merges same-speaker segments across a short gap
before min_duration_on drops the segments still too short, then ids
are renumbered. num_speakers/min_speakers/max_speakers/clustering_
threshold have no Sortformer equivalent and are logged at debug
instead of rejected.

Verified against the real Nemotron-3-Diarization + parakeet-tdt_ctc-
110m checkpoints on the two_speakers.wav fixture: correct A-B-A-B
speaker segmentation and matching speaker-attributed transcripts.

* feat(parakeet-cpp): add sound event detection

Wire the SoundDetection RPC to the CED tagger context (p.tagCtx)
loaded by Task 1's role classification. It runs the whole clip
through a one-shot parakeet_capi_sound_stream_* session (window
10s, hop 10s, top_k set to the tagger's class count so every
drained window carries a full score list), averages each class's
score across the drained windows, sorts descending, then applies
the request's threshold and top_k (0 keeps every class).

No tagCtx returns FailedPrecondition; a libparakeet.so missing the
sound_stream symbols returns Unimplemented. Every C call runs under
engineMu, and the stream is always freed, even when a feed or drain
call fails partway through.

Verified against a real ced-tiny-q8_0.gguf on the rooster.wav demo
clip: "Chicken, rooster" tops the list at score 0.91.

* fix(parakeet-cpp): cancel sound detection mid-feed, shrink the lock

SoundDetection now checks ctx before each 10 s feed slice (mirroring
driver.go's feedSlices) and returns Canceled if the caller gave up,
so a long clip can be interrupted instead of feeding to completion
regardless. The stream is still freed on every path, cancellation
included.

Also narrow engineMu to the C calls: the drained JSON document is
now decoded after the lock is released, splitting soundStreamScores
into a locked soundStreamDrain (opts, begin, feed, drain, free) and
an unlocked json.Unmarshal.

* feat(parakeet-cpp): stream speaker and sound events during live transcription

Add two additive proto fields, LiveSpeakerSegment and LiveSoundEvent,
repeated on TranscriptLiveResponse. When a diarization or sound
companion model is loaded, AudioTranscriptionLive now runs a no-ASR
scene stream (parakeet_capi_scene_stream_begin) beside the ASR
streaming session, feeding it the same PCM slices and forwarding any
closed speaker or sound events alongside the matching ASR delta, or
on their own when a slice has no ASR output.

The scene stream is freed and reopened on a mid-stream Config reset,
flushed with is_last before the closing FinalResult, and degrades
gracefully (a warning, not an error) when begin or a later feed call
fails, so live transcription keeps working ASR-only. Existing live
behavior is unchanged when no companion is configured, and no scene
C call is made in that case.

* fix(parakeet-cpp): keep scene events off the ASR critical path in live

Emit each slice's ASR result right after the ASR feed, before the
scene feed for that slice runs, so a companion diarization/sound
model never adds scene compute latency in front of the delta or
<EOU> that drives realtime turn detection. Closed speakers/sounds go
out afterward as their own response, so a slice with both now
produces two responses, ASR first. The live feed log line now
reports ASR and scene wall time separately.

Re-check the diarization/sound contexts a scene stream was begun
with against the live contexts before every feed, under the same
lock: Free() can race between an ASR feed and the matching scene
feed and free the model the stream borrows. A mismatch now returns
without touching the C side. Freeing the stream itself stays
unconditional; the scene stream's destructor only releases its own
buffers and never touches the borrowed contexts.

Also recover a panicking stub inside the live test goroutine instead
of crashing the test binary, and reset the live decode-lag tracker on
a mid-stream config reset, matching what its own comment already
promised.

Each speaker segment emits

Also: audio-diarization.md now says getting per-segment text needs
both an asr_model companion and include_text=true on the request, and

loadRoles let a companion option (asr_model:/diarization_model:/

for example asr_model: on an already-ASR primary. The companion's
context silently overwrote ctxPtr/diarCtx/tagCtx, and Free() only
walks those three fields, so the original primary context was never
freed again.

Reject a companion whose role the primary already holds before its
GGUF is even loaded, freeing everything loadRoles opened so far, the
same way a wrong-kind companion is already rejected.

Also warn, rather than silently fall through, when
parakeet_capi_model_kind reports PARAKEET_MODEL_KIND_NONE for a
successfully loaded primary; the primary is still treated as ASR,
matching today's behavior.

* fix(parakeet-cpp): cap live scene sound score retention

sceneBegin started the live diarization/sound companion stream with
the C API's default sound options, whose top_k keeps 5 scores per
window forever until drained. The live scene path never drains sound
scores (only the offline SoundDetection RPC does, with its own fresh
stream), so this window queue on the C side grew for the whole
session's lifetime.

Set opts.Sound.TopK = 0 before starting the scene stream: this
disables score retention while leaving sound event detection (onset/
offset), which the live path actually consumes, unaffected.

* fix(parakeet-cpp): merge diarization segments per speaker, harden Diarize

mergeCloseSegments only compared neighbors in the single start-sorted
segment list, so two same-speaker segments never merged once another
speaker's turn fell between them (A, B, A): the short B segment broke
the adjacency the merge relied on. Group segments by speaker first,
merge within each speaker's own start-ordered run, then re-sort the
result by start so interleaved speakers come back out in timeline
order.

Also harden Diarize's entry points the same way streamFeedDoc/
sceneFeed already are: diarizeCall re-checks p.diarCtx (and, on the
include_text path, p.ctxPtr) under engineMu right before the C call,
so a Free() racing between Diarize's own checks and the lock can no
longer reach the C side with a freed context. When the include_text
call returns NULL, last_error is now read from both contexts and
whichever came back non-empty is reported, since either side of the
pairing can be the one that failed. A WAV decode failure is reported
as InvalidArgument instead of an unwrapped/untyped error.

* docs: fix the parakeet-cpp companion role table and realtime scene docs

audio-to-text.md's companion option table read "Use on" with a note
that the loader did not enforce the pairing; it now rejects a
companion whose role duplicates the primary's, so restore the
"Allowed on" wording and describe the real enforcement.

openai-realtime.md's live speaker/sound section claimed a mid-stream
session.update resets the companion stream and that it flushes on
session close; neither happens, since the realtime core opens one
live stream (and so one scene stream) per speech turn and closes it
at that turn's commit, with no mid-stream Config in between. Document
that lifecycle instead, state precisely that start/end are seconds
from the start of the turn's own audio, and note that the diarization
model starts a fresh session every turn, so a speaker index is only
meaningful within one turn. The example sound tag ("Rooster", index
17) did not match any real CED label; index 17 in ced-tiny-q8_0.gguf
is "Baby laughter". Replaced with "Chicken, rooster" at its real

its segments.

TranscriptWord gains an optional speaker (proto field 4, additive).
It flows through the live event and result mapping, the JSON word
output of the endpoint and the CLI, and transcript.text.done now
includes a segment's speaker when there is one. Empty labels are

pipeline.diarization (off by default) asks the transcription model for
speaker labels on each committed turn and emits every labelled segment

Measured on CPU over a 37 s clip: the live diarization + sound stream

Ettore Di Giacinto 8db6c15fe0 refactor: name the proxy backends with constants
Review asked for constants instead of the "cloud-proxy" and
"localai-proxy" literals. Add CloudProxyBackend and LocalAIProxyBackend next
to the other backend-name constants in pkg/model (WhisperBackend,
TransformersBackend, ...), which core/config already imports, and use them
in every production check: the proxy options builder, IsRemoteProxy,
IsCloudProxyBackendPassthrough, the PII defaults, the localai-proxy backend
hook and loader warning, and the PII middleware metadata in the routes and
the in-process MCP client.

The proxy options builder now calls IsRemoteProxy() instead of repeating
the two-backend check, so the set of proxy backends is defined once.

Ettore Di Giacinto 6df1767133 fix(localai-proxy): keep rerank, stream errors and chat intact through the proxy
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.

localai-org-maint-bot e62854c340 fix(failover): pass credential lookup from CLI
Pass the API key environment lookup through ApplicationConfig to satisfy
core configuration lint. Keep credential resolution dynamic and exclude
the callback from serialization.

Handle the five close results reported by errcheck.

Ettore Di Giacinto f7f12f8203 fix(failover): warn about warm on a remote target, align the spec
The spec promised a load-time warning when a chain marks a remote
target warm, where the flag does nothing; the loader now logs it. The
remote-backend test moves into ModelConfig.IsRemoteProxy so the loader
and the failover manager agree on what is remote.

The spec now says what ships: a load blocked by pinned warm targets
proceeds over the limit after eviction retries, without an error that
names them.

Ettore Di Giacinto b0a4c132ca fix(failover): treat a set-but-empty api_key_env as unset in ResolveAPIKey
Matches cloud-proxy's resolveAPIKey exactly: os.Getenv + empty check
rather than os.LookupEnv, so a variable that's set but empty errors
instead of probing unauthenticated.

Ettore Di Giacinto a7dc8bf42c feat(failover): probe remote targets over HTTP and local ones over gRPC
Remote liveness uses /v1/models, which every OpenAI-compatible upstream
serves. Recovery sends one minimal request for the target's usecase.
