8af963bdd9 fix(streaming): comply with OpenAI usage / stream_options spec (#9815)
* fix(streaming): comply with OpenAI usage / stream_options spec (#8546)

LocalAI emitted `"usage":{"prompt_tokens":0,...}` on every streamed
chunk because `OpenAIResponse.Usage` was a value type without
`omitempty`. The official OpenAI Node SDK and its consumers
(continuedev/continue, Kilo Code, Roo Code, Zed, IntelliJ Continue)
filter on a truthy `result.usage` to detect the trailing usage chunk;
LocalAI's zero-but-non-null usage on every intermediate chunk made
that filter swallow every content chunk and surface an empty chat
response while the server log looked successful.

Changes:

- `core/schema/openai.go`: `Usage *OpenAIUsage \`json:"usage,omitempty"\``
  so intermediate chunks no longer carry a `usage` key. Add
  `OpenAIRequest.StreamOptions` with `include_usage` to mirror OpenAI's
  request field.
- `core/http/endpoints/openai/chat.go` and `completion.go`: keep using
  the `Usage` struct field as an in-process channel for the running
  cumulative, but strip it before JSON marshalling. When the request
  set `stream_options.include_usage: true`, emit a dedicated trailing
  chunk with `"choices": []` and the populated usage (matching the
  OpenAI spec and llama.cpp's server behavior).
- `chat_emit.go`: new `streamUsageTrailerJSON` helper; drop the
  `usage` parameter from `buildNoActionFinalChunks` since chunks no
  longer carry usage.
- Update `image.go`, `inpainting.go`, `edit.go` to wrap their Usage
  values with `&` for the new pointer field.
- UI: send `stream_options:{include_usage:true}` from the React
  (`useChat.js`) and legacy (`static/chat.js`) chat clients so the
  token-count badge keeps populating now that the server is
  spec-compliant.

Tests:

- New `chat_stream_usage_test.go` pins the spec invariants:
  intermediate chunks have no `usage` key, the trailer JSON has
  `"choices":[]` and a populated `usage`, and `OpenAIRequest` parses
  `stream_options.include_usage`.
- Update `chat_emit_test.go` to reflect that finals no longer embed
  usage.

Verified against the live LocalAI instance: before the fix Continue's
filter logic swallowed 16/16 token chunks; with the new shape it
yields 4/5 and routes usage through the dedicated trailer chunk.

Fixes #8546

* fix(streaming): silence errcheck on usage trailer Fprintf

The new spec-compliant `stream_options.include_usage` trailer writes
were flagged by errcheck since they're new code (golangci-lint runs
new-from-merge-base on master); the surrounding `fmt.Fprintf` data:
writes are grandfathered. Drop the return values explicitly to match
the linter's contract without adding a nolint shim.

0245b33eab feat(realtime): Add Liquid Audio s2s model and assistant mode on talk page (#9801)
* feat(liquid-audio): add LFM2.5-Audio any-to-any backend + realtime_audio usecase

Wires LiquidAI's LFM2.5-Audio-1.5B as a self-contained Realtime API model:
single engine handles VAD, transcription, LLM, and TTS in one bidirectional
stream — drop-in alternative to a VAD+STT+LLM+TTS pipeline.

Backend
- backend/python/liquid-audio/ — new Python gRPC backend wrapping the
  `liquid-audio` package. Modes: chat / asr / tts / s2s, voice presets,
  Load/Predict/PredictStream/AudioTranscription/TTS/VAD/AudioToAudioStream/
  Free and StartFineTune/FineTuneProgress/StopFineTune. Runtime monkey-patch
  on `liquid_audio.utils.snapshot_download` so absolute local paths from
  LocalAI's gallery resolve without a HF round-trip. soundfile in place of
  torchaudio.load/save (torchcodec drags NVIDIA NPP we don't bundle).
- backend/backend.proto + pkg/grpc/{backend,client,server,base,embed,
  interface}.go — new AudioToAudioStream RPC mirroring AudioTransformStream
  (config/frame/control oneof in; typed event+pcm+meta out).
- core/services/nodes/{health_mock,inflight}_test.go — add stubs for the
  new RPC to the test fakes.

Config + capabilities
- core/config/backend_capabilities.go — UsecaseRealtimeAudio, MethodAudio
  ToAudioStream, UsecaseInfoMap entry, liquid-audio BackendCapability row.
- core/config/model_config.go — FLAG_REALTIME_AUDIO bitmask, ModalityGroups
  membership in both speech-input and audio-output groups so a lone flag
  still reads as multimodal, GetAllModelConfigUsecases entry, GuessUsecases
  branch.

Realtime endpoint
- core/http/endpoints/openai/realtime.go — extract prepareRealtimeConfig()
  so the gate is unit-testable; accept realtime_audio models and self-fill
  empty pipeline slots with the model's own name (user-pinned slots win).
- core/http/endpoints/openai/realtime_gate_test.go — six specs covering nil
  cfg, empty pipeline, legacy pipeline, self-contained realtime_audio,
  user-pinned VAD slot, and partial legacy pipeline.

UI + endpoints
- core/http/routes/ui.go — /api/pipeline-models accepts either a legacy
  VAD+STT+LLM+TTS pipeline or a realtime_audio model; surfaces a
  self_contained flag so the Talk page can collapse the four cards.
- core/http/routes/ui_api.go — realtime_audio in usecaseFilters.
- core/http/routes/ui_pipeline_models_test.go — covers both code paths.
- core/http/react-ui/src/pages/Talk.jsx — self-contained badge instead of
  the four-slot grid; rename Edit Pipeline → Edit Model Config; less
  pipeline-specific wording.
- core/http/react-ui/src/pages/Models.jsx + locales/en/models.json — new
  realtime_audio filter button + i18n.
- core/http/react-ui/src/utils/capabilities.js — CAP_REALTIME_AUDIO.
- core/http/react-ui/src/pages/FineTune.jsx — voice + validation-dataset
  fields, surfaced when backend === liquid-audio, plumbed via
  extra_options on submit/export/import.

Gallery + importer
- gallery/liquid-audio.yaml — config template with known_usecases:
  [realtime_audio, chat, tts, transcript, vad].
- gallery/index.yaml — four model entries (realtime/chat/asr/tts) keyed by
  mode option. Fixed pre-existing `transcribe` typo on the asr entry
  (loader silently dropped the unknown string → entry never surfaced as a
  transcript model).
- gallery/lfm.yaml — function block for the LFM2 Pythonic tool-call format
  `<|tool_call_start|>[name(k="v")]<|tool_call_end|>` matching
  common_chat_params_init_lfm2 in vendored llama.cpp.
- core/gallery/importers/{liquid-audio,liquid-audio_test}.go — detector
  matches LFM2-Audio HF repos (excludes -gguf mirrors); mode/voice
  preferences plumbed through to options.
- core/gallery/importers/importers.go — register LiquidAudioImporter
  before LlamaCPPImporter.
- pkg/functions/parse_lfm2_test.go — seven specs for the response/argument
  regex pair on the LFM2 pythonic format.

Build matrix
- .github/backend-matrix.yml — seven liquid-audio targets (cuda12, cuda13,
  l4t-cuda-13, hipblas, intel, cpu amd64, cpu arm64). Jetpack r36 cuda-12
  is skipped (Ubuntu 22.04 / Python 3.10 incompatible with liquid-audio's
  3.12 floor).
- backend/index.yaml — anchor + 13 image entries.
- Makefile — .NOTPARALLEL, prepare-test-extra, test-extra,
  docker-build-liquid-audio.

Docs
- .agents/plans/liquid-audio-integration.md — phased plan; PR-D (real
  any-to-any wiring via AudioToAudioStream), PR-E (mid-audio tool-call
  detector), PR-G (GGUF entries once upstream llama.cpp PR #18641 lands)
  remain.
- .agents/api-endpoints-and-auth.md — expand the capability-surface
  checklist with every place a new FLAG_* needs to be registered.

* feat(realtime): function calling + history cap for any-to-any models

Three pieces, all on the realtime_audio path that just landed:

1. liquid-audio backend (backend/python/liquid-audio/backend.py):
   - _build_chat_state grows a `tools_prelude` arg.
   - new _render_tools_prelude parses request.Tools (the OpenAI Chat
     Completions function array realtime.go already serialises) and
     emits an LFM2 `<|tool_list_start|>…<|tool_list_end|>` system turn
     ahead of the user history. Mirrors gallery/lfm.yaml's `function:`
     template so the model sees the same prompt shape whether served
     via llama-cpp or here. Without this the backend silently dropped
     tools — function calling was wired end-to-end on the Go side but
     the model never saw a tool list.

2. Realtime history cap (core/http/endpoints/openai/realtime.go):
   - Session grows MaxHistoryItems int; default picked by new
     defaultMaxHistoryItems(cfg) — 6 for realtime_audio models (LFM2.5
     1.5B degrades quickly past a handful of turns), 0/unlimited for
     legacy pipelines composing larger LLMs.
   - triggerResponse runs conv.Items through trimRealtimeItems before
     building conversationHistory. Helper walks the cut left if it
     would orphan a function_call_output, so tool result + call pairs
     stay intact.
   - realtime_gate_test.go: specs for defaultMaxHistoryItems and
     trimRealtimeItems (zero cap, under cap, over cap, tool-call pair
     preservation).

3. Talk page (core/http/react-ui/src/pages/Talk.jsx):
   - Reuses the chat page's MCP plumbing — useMCPClient hook,
     ClientMCPDropdown component, same auto-connect/disconnect effect
     pattern. No bespoke tool registry, no new REST endpoints; tools
     come from whichever MCP servers the user toggles on, exactly as
     on the chat page.
   - sendSessionUpdate now passes session.tools=getToolsForLLM(); the
     update re-fires when the active server set changes mid-session.
   - New response.function_call_arguments.done handler executes via
     the hook's executeTool (which round-trips through the MCP client
     SDK), then replies with conversation.item.create
     {type:function_call_output} + response.create so the model
     completes its turn with the tool output. Mirrors chat's
     client-side agentic loop, translated to the realtime wire shape.

UI changes require a LocalAI image rebuild (Dockerfile:308-313 bakes
react-ui/dist into the runtime image). Backend.py changes can be
swapped live in /backends/<id>/backend.py + /backend/shutdown.

* feat(realtime): LocalAI Assistant ("Manage Mode") for the Talk page

Mirrors the chat-page metadata.localai_assistant flow so users can ask the
realtime model what's loaded / installed / configured. Tools are run
server-side via the same in-process MCP holder that powers the chat
modality — no transport switch, no proxy, no new wire protocol.

Wire:
- core/http/endpoints/openai/realtime.go:
  - RealtimeSessionOptions{LocalAIAssistant,IsAdmin}; isCurrentUserAdmin
    helper mirrors chat.go's requireAssistantAccess (no-op when auth
    disabled, else requires auth.RoleAdmin).
  - Session grows AssistantExecutor mcpTools.ToolExecutor.
  - runRealtimeSession, when opts.LocalAIAssistant is set: gate on admin,
    fail closed if DisableLocalAIAssistant or the holder has no tools,
    DiscoverTools and inject into session.Tools, prepend
    holder.SystemPrompt() to instructions.
  - Tool-call dispatch loop: when AssistantExecutor.IsTool(name), run
    ExecuteTool inproc, append a FunctionCallOutput to conv.Items, skip
    the function_call_arguments client emit (the client can't execute
    these — it doesn't know about them). After the loop, if any
    assistant tool ran, trigger another response so the model speaks the
    result. Mirrors chat's agentic loop, driven server-side rather than
    via client round-trip.

- core/http/endpoints/openai/realtime_webrtc.go: RealtimeCallRequest
  gains `localai_assistant` (JSON omitempty). Handshake calls
  isCurrentUserAdmin and builds RealtimeSessionOptions.

- core/http/react-ui/src/pages/Talk.jsx: admin-only "Manage Mode"
  checkbox under the Tools dropdown; passes localai_assistant: true to
  realtimeApi.call's body, captured in the connect callback's deps.

Mirroring chat's pattern means the in-process MCP tools surface "just
works" for the Talk page without exposing a Streamable-HTTP MCP endpoint
(which was the alternative). Clients with their own MCP servers can
still use the existing ClientMCPDropdown path in parallel; the realtime
handler distinguishes them by AssistantExecutor.IsTool() at dispatch
time.

* feat(realtime): render Manage Mode tool calls in the Talk transcript

Previously the realtime endpoint only emitted response.output_item.added
for the FunctionCall item, and Talk.jsx's switch ignored the event — so
server-side tool runs were invisible in the UI. The model would speak
the result but the user had no way to see what tool was actually
called.

realtime.go: after executing an assistant tool inproc, emit a second
output_item.added/.done pair for the FunctionCallOutput item. Mirrors
the way the chat page displays tool_call + tool_result blocks.

Talk.jsx: handle both response.output_item.added and .done. Render
FunctionCall (with arguments) and FunctionCallOutput (pretty-printed
JSON when possible) as two transcript entries — `tool_call` with the
wrench icon, `tool_result` with the clipboard icon, both in mono-space
secondary-colour. Resets streamingRef after the result so the next
assistant text delta starts a fresh transcript entry instead of
appending to the previous turn.

* refactor(realtime): bound the Manage Mode tool-loop + preserve assistant tools

Fallout from a review pass on the Manage Mode patches:

- Bound the server-side agentic loop. triggerResponse used to recurse on
  executedAssistantTool with no cap — a model that kept calling tools
  would blow the goroutine stack. New maxAssistantToolTurns = 10 (mirrors
  useChat.js's maxToolTurns). Public triggerResponse is now a thin shim
  over triggerResponseAtTurn(toolTurn int); recursion increments the
  counter and stops at the cap with an xlog.Warn.

- Preserve Manage Mode tools across client session.update. The handler
  used to blindly overwrite session.Tools, so toggling a client MCP
  server mid-session silently wiped the in-process admin tools. Session
  now caches the original AssistantTools slice at session creation and
  the session.update handler merges them back in (client names win on
  collision — the client is explicit).

- strconv.ParseBool for the localai_assistant query param instead of
  hand-rolled "1" || "true". Mirrors LocalAIAssistantFromMetadata.

- Talk.jsx: render both tool_call and tool_result on
  response.output_item.done instead of splitting them across .added and
  .done. The server's event pairing (added → done) stays correct; the
  UI just doesn't need to inspect both phases of the same item. One
  switch case instead of two, no behavioural change.

Out of scope (noted for follow-ups): extract a shared assistant-tools
helper between chat.go and realtime.go (duplication is small enough
that two parallel implementations stay readable for now), and an i18n
key for the Manage Mode helper text (Talk.jsx doesn't use i18n
anywhere else yet).

* ci(test-extra): wire liquid-audio backend smoke test

The backend ships test.py + a `make test` target and is listed in
backend-matrix.yml, so scripts/changed-backends.js already writes a
`liquid-audio=true|false` output when files under backend/python/liquid-audio/
change. The workflow just wasn't reading it.

- Expose the `liquid-audio` output on the detect-changes job
- Add a tests-liquid-audio job that runs `make` + `make test` in
  backend/python/liquid-audio, gated on the per-backend detect flag

The smoke covers Health() and LoadModel(mode:finetune); fine-tune mode
short-circuits before any HuggingFace download (backend.py:192), so the
job needs neither weights nor a GPU. The full-inference path remains
gated on LIQUID_AUDIO_MODEL_ID, which CI doesn't set.

The four new Go test files (core/gallery/importers/liquid-audio_test.go,
core/http/endpoints/openai/realtime_gate_test.go,
core/http/routes/ui_pipeline_models_test.go, pkg/functions/parse_lfm2_test.go)
are already picked up by the existing test.yml workflow via `make test` →
`ginkgo -r ./pkg/... ./core/...`; their packages all carry RunSpecs entries.

670259ce43 chore: Security hardening (#9719)
* fix(http): close 0.0.0.0/[::] SSRF bypass in /api/cors-proxy

The CORS proxy carried its own private-network blocklist (RFC 1918 + a
handful of IPv6 ranges) instead of using the same classification as
pkg/utils/urlfetch.go. The hand-rolled list missed 0.0.0.0/8 and ::/128,
both of which Linux routes to localhost — so any user with FeatureMCP
(default-on for new users) could reach LocalAI's own listener and any
other service bound to 0.0.0.0:port via:

  GET /api/cors-proxy?url=http://0.0.0.0:8080/...
  GET /api/cors-proxy?url=http://[::]:8080/...

Replace the custom check with utils.IsPublicIP (Go stdlib IsLoopback /
IsLinkLocalUnicast / IsPrivate / IsUnspecified, plus IPv4-mapped IPv6
unmasking) and add an upfront hostname rejection for localhost, *.local,
and the cloud metadata aliases so split-horizon DNS can't paper over the
IP check.

The IP-pinning DialContext is unchanged: the validated IP from the
single resolution is reused for the connection, so DNS rebinding still
cannot swap a public answer for a private one between validate and dial.

Regression tests cover 0.0.0.0, 0.0.0.0:PORT, [::], ::ffff:127.0.0.1,
::ffff:10.0.0.1, file://, gopher://, ftp://, localhost, 127.0.0.1,
10.0.0.1, 169.254.169.254, metadata.google.internal.

* fix(downloader): verify SHA before promoting temp file to final path

DownloadFileWithContext renamed the .partial file to its final name
*before* checking the streamed SHA, so a hash mismatch returned an
error but left the tampered file at filePath. Subsequent code that
operated on filePath (a backend launcher, a YAML loader, a re-download
that finds the file already present and skips) would consume the
attacker-supplied bytes.

Reorder: verify the streamed hash first, remove the .partial on
mismatch, then rename. The streamed hash is computed during io.Copy
so no second read is needed.

While here, raise the empty-SHA case from a Debug log to a Warn so
"this download had no integrity check" is visible at the default log
level. Backend installs currently pass through with no digest; the
warning makes that footprint observable without changing behaviour.

Regression test asserts os.IsNotExist on the destination after a
deliberate SHA mismatch.

* fix(auth): require email_verified for OIDC admin promotion

extractOIDCUserInfo read the ID token's "email" claim but never
inspected "email_verified". With LOCALAI_ADMIN_EMAIL set, an attacker
who could register on the configured OIDC IdP under that email (some
IdPs accept self-supplied unverified emails) inherited admin role:

  - first login:  AssignRole(tx, email, adminEmail) → RoleAdmin
  - re-login:     MaybePromote(db, user, adminEmail) → flip to RoleAdmin

Add EmailVerified to oauthUserInfo, parse email_verified from the OIDC
claims (default false on absence so an IdP that omits the claim cannot
short-circuit the gate), and substitute "" for the role-decision email
when verified=false via emailForRoleDecision. The user record still
stores the unverified email for display.

GitHub's path defaults EmailVerified=true: GitHub only returns a public
profile email after verification, and fetchGitHubPrimaryEmail explicitly
filters to Verified=true.

Regression tests cover both the helper contract and integration with
AssignRole, including the bootstrap "first user" branch that would
otherwise mask the gate.

* feat(cli): refuse public bind when no auth backend is configured

When neither an auth DB nor a static API key is set, the auth
middleware passes every request through. That is fine for a developer
laptop, a home LAN, or a Tailnet — the network itself is the trust
boundary. It is not fine on a public IP, where every model install,
settings change, and admin endpoint becomes reachable from the
internet.

Refuse to start in that exact configuration. Loopback, RFC 1918,
RFC 4193 ULA, link-local, and RFC 6598 CGNAT (Tailscale's default
range) all count as trusted; wildcard binds (`:port`, `0.0.0.0`,
`[::]`) are accepted only when every host interface is in one of those
ranges. Hostnames are resolved and treated as trusted only when every
answer is.

A new --allow-insecure-public-bind / LOCALAI_ALLOW_INSECURE_PUBLIC_BIND
flag opts out for deployments that gate access externally (a reverse
proxy enforcing auth, a mesh ACL, etc.). The error message lists this
plus the three constructive alternatives (bind a private interface,
enable --auth, set --api-keys).

The interface enumeration goes through a package-level interfaceAddrsFn
var so tests can simulate cloud-VM, home-LAN, Tailscale-only, and
enumeration-failure topologies without poking at the real network
stack.

* test(http): regression-test the localai_assistant admin gate

ChatEndpoint already rejects metadata.localai_assistant=true from a
non-admin caller, but the gate was open-coded inline with no direct
test coverage. The chat route is FeatureChat-gated (default-on), and
the assistant's in-process MCP server can install/delete models and
edit configs — the wrong handler change would silently turn the LLM
into a confused deputy.

Extract the gate into requireAssistantAccess(c, authEnabled) and pin
its behaviour: auth disabled is a no-op, unauthenticated is 403,
RoleUser is 403, RoleAdmin and the synthetic legacy-key admin are
admitted.

No behaviour change in the production path.

* test(http): assert every API route is auth-classified

The auth middleware classifies path prefixes (/api/, /v1/, /models/,
etc.) as protected and treats anything else as a static-asset
passthrough. A new endpoint shipped under a brand-new prefix — or a
new path that simply isn't on the prefix allowlist — would be
reachable anonymously.

Walk every route registered by API() with auth enabled and a fresh
in-memory database (no users, no keys), and assert each API-prefixed
route returns 401 / 404 / 405 to an anonymous request. Public surfaces
(/api/auth/*, /api/branding, /api/node/* token-authenticated routes,
/healthz, branding asset server, generated-content server, static
assets) are explicit allowlist entries with comments justifying them.

Build-tagged 'auth' so it runs against the SQLite-backed auth DB
(matches the existing auth suite).

* test(http): pin agent endpoint per-user isolation contract

agents.go's getUserID / effectiveUserID / canImpersonateUser /
wantsAllUsers helpers are the single trust boundary for cross-user
access on agent, agent-jobs, collections, and skills routes. A
regression there is the difference between "regular user reads their
own data" and "regular user reads anyone's data via ?user_id=victim".

Lock in the contract:
  - effectiveUserID ignores ?user_id= for unauthenticated and RoleUser
  - effectiveUserID honours it for RoleAdmin and ProviderAgentWorker
  - wantsAllUsers requires admin AND the literal "true" string
  - canImpersonateUser is admin OR agent-worker, never plain RoleUser

No production change — this commit only adds tests.

* fix(http): redact secrets from trace buffer and distribution-token logs

The /api/traces buffer captured Authorization, Cookie, Set-Cookie, and
API-key headers verbatim from every request when tracing was enabled. The
endpoint is admin-only but the buffer is reachable via any heap-style
introspection and the captured tokens otherwise outlive the request.
Strip those header values at capture time. Body redaction is left to a
follow-up — the prompts are usually the operator's own and JSON-walking
is invasive.

Distribution tokens were also logged in plaintext from
core/explorer/discovery.go; logs forward to syslog/journald and outlive
the token. Redact those to a short prefix/suffix instead.

* feat(auth): rate-limit OAuth callbacks separately from password endpoints

The shared 5/min/IP limit on auth endpoints is right for password-style

60/min/IP limiter for /api/auth/{github,oidc}/callback so callbacks are
bounded against floods without breaking shared-IP deployments.

  script-src permissive because the Vite bundle relies on inline + eval'd
  scripts; tightening that requires moving to a nonce-based policy.

- The <base href> injection in the SPA shell escaped attacker-controllable
  Host / X-Forwarded-Host headers — a single quote in the host header
  broke out of the attribute. Pass through SecureBaseHref (html.EscapeString).

- Three React sinks rendering untrusted content via dangerouslySetInnerHTML
  switch to text-node rendering with whiteSpace: pre-wrap: user message
  bodies in Chat.jsx and AgentChat.jsx, and the agent activity log in
  AgentChat.jsx. The hand-rolled escape on the agent user-message variant
  is replaced by the same plain-text path.

- New safeHref util collapses non-allowlisted URI schemes (most
  importantly javascript:) to '#'. Applied to gallery `<a href={url}>`
  links in Models / Backends / Manage and to canvas artifact links —
  these come from gallery JSON or assistant tool calls and must be treated
  as untrusted.

- The branding asset server attaches a sandbox CSP plus same-origin CORP
  to .svg responses. The React UI loads logos via <img>, but the same URL
  is also reachable via direct navigation; this prevents script
  execution if a hostile SVG slipped past upload validation.

* feat(http): bound HTTP server with read-header and idle timeouts

A net/http server with no timeouts is trivially Slowloris-able and leaks
idle keep-alive connections. Set ReadHeaderTimeout (30s) to plug the
slow-headers attack and IdleTimeout (120s) to cap keep-alive sockets.

ReadTimeout and WriteTimeout stay at 0 because request bodies can be
multi-GB model uploads and SSE / chat completions stream for many
minutes; operators who need tighter per-request bounds should terminate
slow clients at a reverse proxy.

UploadDataset and UploadToCollectionForUser took the raw multipart

UploadToCollectionForUser handed the filename to a vendored backend

/browse/* into a 301 to //evil.com/app. The path-strip middleware had
the same shape on its prefix-trailing-slash redirect.

Add SafeForwardedPrefix at the middleware boundary: must start with
a single '/', no protocol-relative '//' opener, no scheme, no
backslash, no control characters. Apply at both consumers; misconfig
trips the validator and the header is dropped.

* feat(auth): zxcvbn password strength check with user-acknowledged override

The previous policy was len < 8, which let through "Password1" and the
rest of the credential-stuffing corpus. LocalAI has no second factor
yet, so the bar needs to sit higher.

Add ValidatePasswordStrength using github.com/timbutler/zxcvbn (an
actively-maintained fork of the trustelem port; v1.0.4, April 2024):
- min 12 chars, max 72 (bcrypt's truncation point)
- reject NUL bytes (some bcrypt callers truncate at the first NUL)
- require zxcvbn score >= 3 ("safely unguessable, ~10^8 guesses to
  break"); the hint list ["localai", "local-ai", "admin"] penalises
  passwords built from the app's own branding

zxcvbn produces false positives sometimes (a strong-looking password
that happens to match a dictionary word) and operators occasionally
need to set a known-weak password (kiosk demos, CI rigs). Add an
acknowledgement path: PasswordPolicy{AllowWeak: true} skips the
entropy check while still enforcing the hard rules. The structured
PasswordErrorResponse marks weak-password rejections as Overridable
so the UI can surface a "use this anyway" checkbox.

Wired through register, self-service password change, and admin
password reset on both the server and the React UI.

no toast, no fetch, no clue. Reproducible by typing fewer than 12

The JS-level length check in handleSubmit already shows a toast and

* feat(auth): make password length-floor overridable like the entropy check

The 12-char minimum was a policy choice, not a technical invariant —
only "non-empty", "<= 72 bytes", and "no NUL bytes" are real bcrypt
constraints. Treating length-12 as a hard rule was inconsistent with
the entropy check (already overridable) and friction for use cases
where the account is just a name on a session, not a security
boundary (single-user kiosk, CI rig, lab demo).

Restructure ValidatePasswordStrength:
- Hard rules (always enforced): non-empty, <= MaxPasswordLength, no NUL byte
- Policy rules (skipped when AllowWeak=true): length >= 12, zxcvbn score >= 3

PasswordError now marks password_too_short as Overridable too. The
React forms generalised from `error_code === 'password_too_weak'` to
`overridable === true`, and the JS-side preflight length checks were
removed (server is source of truth, returns the same checkbox flow).

a late CppSetAbort(1) from a cancelled call could land on the next

polling the abort callback, corrupting the second transcription.

595b6fd22d feat(api/transcription): include segments + duration + language on stream done event (#9709)
streamTranscription previously emitted a done event with just `text`,
matching the OpenAI streaming spec exactly. Streaming clients that need
per-utterance timings or audio duration had to fall back to the
non-streaming JSON path — and that path is exactly the one that trips
on ResponseHeaderTimeout when whisper requests queue behind each other
on a SingleThread backend.

Extend the done event to additively carry `language`, `duration`, and
a `segments` array (id, start, end, text — start/end as float seconds,
matching TranscriptionSegmentSeconds). Empty / zero values are still
omitted; spec-compliant clients ignore the new fields.

This unblocks notary's streaming Transcribe (companion change in the
notary repo) so it produces the same TranscriptionResult shape as the
JSON path while sidestepping the queue-induced header timeouts.

cec5c4fdfc fix(http): make handler-error status visible in access log + transcription errors (#9707)
* fix(http): log accurate status code when handler returns error

The custom xlog access-log middleware in API() reads res.Status
*before* Echo's central HTTPErrorHandler runs, so when a handler
returns an error without writing a response (e.g.
TranscriptEndpoint's `return err` on backend failure) the status
field stays at its default 200. The logged line then claims
status=200 while the client receives 500 — silently hiding every
500/503/etc. that bubbles up through Echo's error handler.

Mirror echo.DefaultHTTPErrorHandler's status derivation when
err != nil and the response hasn't been committed: default to 500,
upgrade to *echo.HTTPError.Code if applicable. The logged status now
matches what the client actually sees, so failed transcription
requests stop appearing as 200 in the access log.

* fix(transcription): log underlying error before returning 500 to client

ModelTranscriptionWithOptions surfaces real failures — gRPC errors
from a remote node, model load problems, ffmpeg conversion crashes —
but TranscriptEndpoint just did `return err`, so Echo turned it into
a 500 with a generic body and the original error was lost. Operators
chasing transcription failures across distributed mode were left
with "upstream returned 500" on the client and zero context anywhere
in the frontend's logs.

Add an xlog.Error before returning, recording model name, the staged
audio path, and the underlying error. Combined with the access-log
status fix, a failing transcription now leaves an audit trail (real
status code in the access line, real cause in an Error line) instead
of vanishing.

e86ade54a6 feat(api): add /v1/audio/diarization endpoint with sherpa-onnx + vibevoice.cpp (#9654)
* feat(api): add /v1/audio/diarization endpoint with sherpa-onnx + vibevoice.cpp

Closes #1648.

OpenAI-style multipart endpoint that returns "who spoke when". Single
endpoint instead of the issue's three-endpoint sketch (refactor /vad,
/vad/embedding, /diarization) — the typical client wants one call, and
embeddings can land later as a sibling without breaking this surface.

Response shape borrows from Pyannote/Deepgram: segments carry a
normalised SPEAKER_NN id (zero-padded, stable across the response) plus
the raw backend label, optional per-segment text when the backend bundles
ASR, and a speakers summary in verbose_json. response_format also accepts
rttm so consumers can pipe straight into pyannote.metrics / dscore.

Backends:

* vibevoice-cpp — Diarize() reuses the existing vv_capi_asr pass.
  vibevoice's ASR prompt asks the model to emit
  [{Start,End,Speaker,Content}] natively, so diarization is a by-product
  of the same pass; include_text=true preserves the transcript per
  segment, otherwise we drop it.

* sherpa-onnx — wraps the upstream SherpaOnnxOfflineSpeakerDiarization
  C API (pyannote segmentation + speaker-embedding extractor + fast
  clustering). libsherpa-shim grew config builders, a SetClustering
  wrapper for per-call num_clusters/threshold overrides, and a
  segment_at accessor (purego can't read field arrays out of
  SherpaOnnxOfflineSpeakerDiarizationSegment[] directly).

Plumbing: new Diarize gRPC RPC + DiarizeRequest / DiarizeSegment /
DiarizeResponse messages, threaded through interface.go, base, server,
client, embed. Default Base impl returns unimplemented.

Capability surfaces all updated: FLAG_DIARIZATION usecase,
FeatureAudioDiarization permission (default-on), RouteFeatureRegistry
entries for /v1/audio/diarization and /audio/diarization, audio
instruction-def description widened, CAP_DIARIZATION JS symbol,
swagger regenerated, /api/instructions discovery map updated.

Tests:

* core/backend: speaker-label normalisation (first-seen → SPEAKER_NN,
  per-speaker totals, nil-safety, fallback to backend NumSpeakers when
  no segments).

* core/http/endpoints/openai: RTTM rendering (file-id basename, negative
  duration clamping, fallback id).

* tests/e2e: mock-backend grew a deterministic Diarize that emits
  raw labels "5","2","5" so the e2e suite verifies SPEAKER_NN
  remapping, verbose_json speakers summary + transcript pass-through
  (gated by include_text), RTTM bytes content-type, and rejection of
  unknown response_format. mock-diarize model config registered with
  known_usecases=[FLAG_DIARIZATION] to bypass the backend-name guard.

* fix(diarization): correct sherpa-onnx symbol name + lint cleanup

CI failures on #9654:

* sherpa-onnx-grpc-{tts,transcription} and sherpa-onnx-realtime panicked
  at backend startup with `undefined symbol: SherpaOnnxDestroyOfflineSpeakerDiarizationResult`.
  Upstream's actual symbol is SherpaOnnxOfflineSpeakerDiarizationDestroyResult
  (Destroy in the middle, not the prefix); the rest of the diarization
  surface follows the same naming pattern. The mismatched name made
  purego.RegisterLibFunc fail at dlopen time and crashed the gRPC server
  before the BeforeAll could probe Health, taking down every sherpa-onnx
  test job — not just the diarization-related ones.

* golangci-lint flagged 5 errcheck violations on new defer cleanups
  (os.RemoveAll / Close / conn.Close); wrap each in a `defer func() { _ = X() }()`
  closure (matches the pattern other LocalAI files use for new code, since
  pre-existing bare defers are grandfathered in via new-from-merge-base).

* golangci-lint also flagged forbidigo violations: the new
  diarization_test.go files used testing.T-style `t.Errorf` / `t.Fatalf`,
  which are forbidden by the project's coding-style policy
  (.agents/coding-style.md). Convert both files to Ginkgo/Gomega
  Describe/It with Expect(...) — they get picked up by the existing
  TestBackend / TestOpenAI suites, no new suite plumbing needed.

* modernize linter: tightened the diarization segment loop to
  `for i := range int(numSegments)` (Go 1.22+ idiom).

Verified locally: golangci-lint with new-from-merge-base=origin/master
reports 0 issues across all touched packages, and the four mocked
diarization e2e specs in tests/e2e/mock_backend_test.go still pass.

* fix(vibevoice-cpp): convert non-WAV input via ffmpeg + raise ASR token budget

Confirmed end-to-end against a real LocalAI instance with vibevoice-asr-q4_k
loaded and the multi-speaker MP3 sample at vibevoice.cpp/samples/2p_argument.mp3:
both /v1/audio/transcriptions and /v1/audio/diarization now succeed and
return correctly attributed speaker turns for the full clip.

Two latent issues surfaced once the diarization endpoint actually exercised
the backend with a non-trivial input:

1. vv_capi_asr only accepts WAV via load_wav_24k_mono. The previous code
   passed the uploaded path straight through, so anything that wasn't
   already a 24 kHz mono s16le WAV failed at the C side with rc=-8 and
   the very unhelpful "vv_capi_asr failed". prepareWavInput shells out
   to ffmpeg ("-ar 24000 -ac 1 -acodec pcm_s16le") in a per-call temp
   dir, matching the rate the model was trained on; both AudioTranscription
   and Diarize now route through it. This is the same shape sherpa-onnx
   uses (utils.AudioToWav), but vibevoice needs 24 kHz rather than 16 kHz
   so we don't reuse that helper.

2. The C ABI's max_new_tokens defaults to 256 when 0 is passed. That's
   fine for a five-second clip but not for anything past ~10 s — vibevoice
   stops mid-JSON, the parse fails, and the caller sees a hard error.
   Pass a much larger budget (16 384 ≈ ~9 minutes of speech at the
   model's ~30 tok/s rate); generation stops at EOS so this is a cap
   rather than a target.

3. As a defensive belt-and-braces, mirror AudioTranscription's existing
   "fall back to a single segment if the model emits non-JSON text"
   pattern in Diarize, so partial / unusual model output never produces
   a 500. This kept the endpoint usable while diagnosing (1) and (2),
   and is the right behaviour to keep.

* fix(vibevoice-cpp): pass valid WAVs through directly so ffmpeg is not required at runtime

Spotted by tests-e2e-backend (1.25.x): the previous fix forced every
incoming audio file through `ffmpeg -ar 24000 ...`, which meant the
backend container — which does not ship ffmpeg — failed even for the
existing happy path where the caller already uploads a WAV. The
container-side error was:

    rpc error: code = Unknown desc = vibevoice-cpp: ffmpeg convert to
    24k mono wav: exec: "ffmpeg": executable file not found in $PATH

Reading vibevoice.cpp's audio_io.cpp, `load_wav_24k_mono` uses drwav and
already accepts any PCM/IEEE-float WAV at any sample rate, downmixes
multi-channel input to mono, and resamples to 24 kHz internally. So the
only inputs that genuinely need an external converter are non-WAV
formats (MP3, OGG, FLAC, ...).

Detect WAVs by RIFF/WAVE magic at bytes 0..3 / 8..11 and pass them
straight through with a no-op cleanup; everything else still goes
through ffmpeg with the same 24 kHz mono s16le target. The result:

* Container builds without ffmpeg keep working for WAV uploads
  (the e2e-backends fixture is jfk.wav at 16 kHz mono s16le).
* MP3 and other non-WAV inputs still get the new ffmpeg conversion
  path so the diarization endpoint stays useful.
* If the caller uploads a non-WAV but ffmpeg isn't on PATH, the
  surfaced error is still descriptive enough to act on.

backend-jobs(*-nvidia-l4t-arm64-{stablediffusion-ggml, sam3-cpp, whisper,
acestep-cpp, qwen3-tts-cpp, vibevoice-cpp}). LocalVQE itself is only
matrix-built on ubuntu:24.04 (CPU + Vulkan), so it doesn't actually
need gcc-14 anywhere else.

Make the gcc-14 install conditional on the package being available in
the configured apt repos. On noble: identical behaviour to today (gcc-14
installed, update-alternatives points at it). On jammy: skip the
gcc-14 stanza entirely and let build-essential's default gcc take over,
which is what the other Go backends compile with anyway.

bcef72b9c1 feat: localai assistant chat modality (#9602)
* fix(tests): inline model_test fixtures after tests/models_fixtures removal

The previous reorg removed tests/models_fixtures/ but core/config/model_test.go
still read CONFIG_FILE/MODELS_PATH env vars pointing into that directory, so
`make test` failed with "open : no such file or directory" on the readConfigFile
spec (the suite ran with --fail-fast and bailed before openresponses_test).

Inline the YAMLs (config/embeddings/grpc/rwkv/whisper) directly into the test
file, materialise them into a per-test tmpdir via BeforeEach, and drop the
env-var lookups. The test no longer depends on Makefile plumbing.

* refactor(modeladmin): extract model-admin helpers into a service package

Lift the bodies of EditModelEndpoint, PatchConfigEndpoint,
ToggleStateModelEndpoint, TogglePinnedModelEndpoint and
VRAMEstimateEndpoint into core/services/modeladmin so the same logic can
be called by non-HTTP clients (notably the in-process MCP server that
backs the LocalAI Assistant chat modality, landing in a follow-up commit).

The HTTP handlers shrink to thin shells that parse echo inputs, call the
matching helper, map typed errors (ErrNotFound, ErrConflict,
ErrPathNotTrusted, ErrBadAction, ...) to the existing HTTP status codes,
and render the existing response shapes. No REST-surface behaviour change;
the existing localai endpoint tests cover the regression net.

Adds focused unit tests for each helper against tmp-dir-backed
ModelConfigLoader fixtures (deep-merge patch, rename + conflict, path
separator guard, toggle/pin enable/disable, sync callback).

* feat(assistant): LocalAI Assistant chat modality with in-memory MCP server

Adds a chat modality, admin-only, that wires the chat session to an
in-memory MCP server exposing LocalAI's own admin/management surface as
tools. An admin can install models, manage backends, edit configs and
check status by chatting; the LLM calls tools like gallery_search,
install_model, import_model_uri, list_installed_models, edit_model_config
and surfaces the results.

Same Go package powers two modes:

  pkg/mcp/localaitools/

    NewServer(client, opts) builds an MCP server that registers the
    19-tool admin catalog. The LocalAIClient interface has two impls:

    - inproc.Client — calls services directly (no HTTP loopback,
      no synthetic admin API key). Used in-process by the chat handler.
    - httpapi.Client — calls the LocalAI REST API. Used by the new
      `local-ai mcp-server --target=…` subcommand to control a remote
      LocalAI from a stdio MCP host.

    Tools and their embedded skill prompts are agnostic to which client
    backs them. Skill prompts are markdown files under prompts/, embedded
    via go:embed and assembled into the system prompt at server init.

Wiring:

  - core/http/endpoints/mcp/localai_assistant.go — process-wide holder
    that spins up the in-memory MCP server once at Application start
    using paired net.Pipe transports, then reuses LocalToolExecutor
    (no fork) for every chat request that opts in.

  - core/http/endpoints/openai/chat.go — small branch ahead of the
    existing MCP block: when metadata.localai_assistant=true,
    defense-in-depth admin check + executor swap + system-prompt
    injection. All downstream tool dispatch is unchanged.

  - core/http/auth/{permissions,features}.go — adds
    FeatureLocalAIAssistant; gating happens at the chat handler entry
    plus admin-only `/api/settings`.

  - core/cli/{run.go,cli.go,mcp_server.go} —
    LOCALAI_DISABLE_ASSISTANT flag (runtime-toggleable via Settings, no
    restart), plus `local-ai mcp-server` stdio subcommand.

  - core/config/runtime_settings.go — `localai_assistant_enabled`
    runtime setting; the chat handler reads `DisableLocalAIAssistant`
    live at request entry.

UI:

  - Home.jsx — prominent self-explanatory CTA card on first run
    ("Manage LocalAI by chatting"); collapses to a compact
    "Manage by chat" button in the quick-links row once used,
    persisted via localStorage.
  - Chat.jsx — admin-only "Manage" toggle in the chat header,
    "Manage mode" badge, dedicated empty-state copy, starter chips.
  - Settings.jsx — "LocalAI Assistant" section with the runtime
    enable toggle.
  - useChat.js — `localaiAssistant` flag on the chat schema; injects
    `metadata.localai_assistant=true` on requests when active.

Distributed mode: the in-memory MCP server lives only on the head node;
inproc.Client wraps already-distributed-aware services so installs
propagate to workers via the existing GalleryService machinery.

Documentation: `.agents/localai-assistant-mcp.md` is the contributor
contract — when adding an admin REST endpoint, also add a LocalAIClient
method, an inproc + httpapi impl, a tool registration, and a skill
prompt update; the AGENTS.md index links to it.

Out of scope (follow-ups): per-tool RBAC granularity for non-admin
read-only access; streaming mcp_tool_progress for long installs;
React Vitest rig for the UI changes.

* refactor(assistant): extract tool/capability/MiB/server-name constants

The MCP tool surface, capability tag set, server-name default, and the
chat-handler metadata key were repeated as bare string literals across
seven files. Renaming any one required hand-editing every call site and
risked code/test/prompt drift.

This pulls them into typed constants:

- pkg/mcp/localaitools/tools.go — Tool* constants for the 19 MCP tools,
  plus DefaultServerName.
- pkg/mcp/localaitools/capability.go — typed Capability + constants for
  the capability tag set the LLM passes to list_installed_models. The
  type rides through LocalAIClient.ListInstalledModels and replaces the
  triplet of "embed"/"embedding"/"embeddings" with the single
  CapabilityEmbeddings.
- pkg/mcp/localaitools/inproc/client.go — bytesPerMiB constant for the
  VRAMEstimate byte→MB conversion.
- core/http/endpoints/mcp/tools.go — MetadataKeyLocalAIAssistant for the
  "localai_assistant" request-metadata key consumed by the chat handler.

Tool registrations, the test catalog, the dispatch table, the validation
fixtures, and the fake/stub clients all reference the constants. The
embedded skill prompts under prompts/ keep their bare strings (go:embed
markdown can't import Go constants); the existing TestPromptsContain
SafetyAnchors guards the alignment.

No behaviour change. All tests pass with -race.

* refactor(modeladmin): typed Action for ToggleState/TogglePinned

The toggle/pin verbs were bare strings everywhere — handler signatures,
service implementations, MCP tool args, the fake/stub clients, the
inproc and httpapi LocalAIClient impls, plus 4 test files. A typo in
any caller silently fell through to the runtime "must be 'enable' or
'disable'" check.

Introduce core/services/modeladmin.Action (string alias) with
ActionEnable, ActionDisable, ActionPin, ActionUnpin and a small Valid
helper. The compiler now catches mismatches at every boundary; renames
ripple through one source of truth.

LocalAIClient.ToggleModelState/Pinned signatures change to take
modeladmin.Action. The package is brand-new and unreleased so this is
a free public-API tightening.

* fix(assistant): respect ctx cancellation on gallery channel sends

InstallModel, DeleteModel, ImportModelURI, InstallBackend and
UpgradeBackend all pushed onto galleryop channels with bare sends. If the
worker was paused or the buffer full, the chat-handler goroutine blocked
forever — the LLM kept polling and the request leaked.

Wrap the five sends in a sendModelOp/sendBackendOp helper that selects
on ctx.Done() so a cancelled chat completion surfaces context.Canceled
back to the LLM instead of hanging.

Adds inproc/client_test.go with a pre-cancelled-ctx regression test on
InstallModel; the helpers are shared so the same guarantee covers the
other four call sites.

* fix(assistant): graceful shutdown for in-memory holder and stdio CLI

Two related leaks:

- Application.start() built the LocalAIAssistantHolder but never wired
  Close() into the graceful-termination chain — the in-memory MCP
  transport pair stayed alive until process exit, and the goroutines
  behind net.Pipe() didn't drain. Hook into the existing
  signals.RegisterGracefulTerminationHandler chain (same pattern as
  core/http/endpoints/mcp/tools.go:770).

- core/cli/mcp_server.go ran srv.Run with context.Background(); a
  Ctrl-C from the host (Claude Desktop, mcphost, npx inspector) or a
  SIGTERM from process supervision left the stdio loop reading from a
  closed pipe. Switch to signal.NotifyContext to surface the signal
  through ctx and let srv.Run drain.

* fix(assistant): typed HTTPError + propagate prompt walk error

The httpapi client detected "no such job" by substring-matching on the
error string ("404", "could not find") — brittle to status-code
formatting changes and to LocalAI fixing /models/jobs/:uuid to return a
proper 404. Replace with a typed *HTTPError whose Is() method honours
errors.Is(err, ErrHTTPNotFound). The 500-with-"could not find" branch
stays as a transitional fallback documented in Is().

Same change covers ListNodes' 404 fallback for the /api/nodes endpoint.

Adds httptest tests for both 404 and the legacy 500 path, plus a
direct errors.Is exposure test so external callers (the standalone
stdio CLI host) can match without re-string-parsing.

Also tightens prompts.SystemPrompt: panic when fs.WalkDir on the
embedded FS fails. The only realistic cause is a build-time //go:embed
misconfiguration; serving an empty system prompt to the LLM is much
worse than crashing init. TestSystemPromptIncludesAllEmbeddedFiles
catches regressions in CI.

* fix(modeladmin): atomic writes for model config files

The five sites that wrote model YAML used os.WriteFile, which opens
with O_TRUNC|O_WRONLY|O_CREATE. A crash mid-write left the destination
truncated and the model unloadable until manual repair. Pre-existing
behaviour inherited from the original endpoint handlers — fix once now
that there's a single helper.

Adds writeFileAtomic: writes to a sibling temp file, chmods, syncs via
Close(), then os.Rename. Same-directory temp keeps the rename atomic on
the same filesystem; cleanup runs on every error path so stray temps
don't accumulate. No new dependency.

Applied to:
- ConfigService.PatchConfig
- ConfigService.EditYAML (both rename and in-place branches)
- mutateYAMLBoolFlag (drives ToggleState + TogglePinned)

atomic_test.go covers the happy path plus a read-only-dir failure case
that asserts the original file is preserved (skipped on Windows where
the chmod trick is POSIX-specific).

* chore(assistant): prune dead code, mark stub, document conventions

Three small cleanups landing together:

- Drop the unused errNotImplemented sentinel from inproc/client.go.
  All five methods that used to return it are wired to modeladmin
  helpers since the Phase B commit; the package var is dead.

- Annotate httpapi.Client.GetModelConfig as a known stub. LocalAI's
  /models/edit/:name returns rendered HTML, not JSON, so the standalone
  CLI's get_model_config tool surfaces a clear error to the LLM. A
  future JSON-only /api/models/config-yaml/:name endpoint is tracked in
  the agent contract; FIXME points at it.

- Extend `.agents/localai-assistant-mcp.md` with a "Code conventions"
  section that documents the audit-driven rules: tool/Capability/Action
  constants, errors.Is over substring matching, ctx-aware channel
  sends, atomic writes, and graceful shutdown. Refresh the file map so
  it lists tools.go and capability.go and drops the removed
  tools_bootstrap.go.

The tools_models.go diff is a comment-only change explaining why the
ModelName empty-string check stays at the tool layer (consistency
across LocalAIClient implementations, since the SDK schema validator
only enforces presence, not non-empty).

* test(assistant): convert test files to ginkgo + gomega

The repo convention (per core/http/endpoints/localai/*_test.go,
core/gallery/**, etc.) is Ginkgo v2 with Gomega assertions. The tests I
introduced for the assistant feature used vanilla testing.T, which made
them stand out and stripped the BDD structure the rest of the suite
relies on.

    parity_test.go         — Describe("LocalAIClient parity"),

                              is package localaitools_test so it can
                              import httpapi without an import cycle;

    atomic_test.go         — Describe("writeFileAtomic")

    localai_assistant_test.go — Describe("LocalAIAssistantHolder")

Each package gets a `*_suite_test.go` with the standard
`RegisterFailHandler(Fail) + RunSpecs(t, "...")` boilerplate. Helpers
that previously took *testing.T (newTestService, writeModelYAML,
readMap, sortedStrings, sortGalleries, etc.) drop the *T receiver and
use Gomega Expectations directly. tmp dirs come from GinkgoT().TempDir().

No semantic change to test coverage — every original assertion has a
direct Gomega counterpart. All suites pass with -race.

* test+docs(assistant): drift detector for Tool ↔ REST route mapping

Honest gap from the audit: the parity_test.go suite only checks four
methods, and uses the same httpapi.Client for both sides — it asserts
stability of the DTO shapes, not equivalence between in-process and
HTTP. If a contributor adds an admin REST endpoint without an MCP tool,
or a tool without a matching httpapi route, both surfaces silently
diverge.

Add a coverage test plus stronger docs:

- pkg/mcp/localaitools/coverage_test.go introduces a hand-maintained
  toolToHTTPRoute map: every Tool* constant must list the REST endpoint
  the httpapi.Client hits (or "(none)" with a documented reason). Two
  Ginkgo specs assert the map and the published catalog stay in sync —
  one fails when a Tool is added without a route entry, the other fails
  when a route entry references a tool that no longer exists. Verified
  by removing the ToolDeleteModel entry locally; the test fired with a
  clear message pointing the contributor at the file.

  Deliberate non-test: we don't enumerate live admin REST routes from
  here. Walking the route registry requires booting Application;
  parsing core/http/routes/localai.go is brittle. The "new admin REST
  endpoint → MCP tool" direction stays a PR checklist item — see below.

- AGENTS.md gets a new Quick Reference bullet that calls out the rule
  and points at the test by name.

- .agents/api-endpoints-and-auth.md tightens the existing "Companion:
  MCP admin tool surface" subsection from "if useful, consider..." to
  "MUST be considered, with three concrete outcomes (tool added,
  deliberately skipped with documented reason, or forgot — which
  breaks the contract)". Adds a checklist item at the bottom of the
  file's authoritative checklist.

* refactor(assistant): drop duplicate DTOs, surface canonical types

Audit feedback: localaitools/dto.go reinvented several types that already
existed in the codebase. Replace the duplicates with the canonical types
so the LLM-visible wire format stays aligned with the rest of LocalAI by
construction (no parallel structs to keep in sync).

Removed (and the canonical type now used by the LocalAIClient interface):

  localaitools.Gallery          → config.Gallery
  localaitools.GalleryModelHit  → gallery.Metadata
  localaitools.VRAMEstimate     → vram.EstimateResult

Tightened scope:

  localaitools.Backend          → kept, but reduced to {Name, Installed}.
                                  ListKnownBackends now returns
                                  []schema.KnownBackend (the canonical
                                  type already used by REST /backends/known).

Kept with documented rationale:

  localaitools.JobStatus       — galleryop.OpStatus has Error error which
                                 marshals to "{}". JobStatus is the
                                 JSON-friendly mirror.
  localaitools.Node            — nodes.BackendNode carries gorm internals
                                 + token hash; we expose only the
                                 LLM-relevant fields.
  ImportModelURIRequest/Response — schema.ImportModelRequest and
                                   GalleryResponse are wire-shaped, mine
                                   are LLM-shaped (BackendPreference flat,
                                   AmbiguousBackend exposed).

Side wins:

  - Drop bytesPerMiB; vram.EstimateResult already carries human-readable
    display strings (size_display, vram_display) the LLM uses directly.
  - Drop the handler-private vramEstimateRequest in
    core/http/endpoints/localai/vram.go and bind directly into
    modeladmin.VRAMRequest (now JSON-tagged).

Both clients pass through these types now where possible (e.g.
ListGalleries in inproc.Client is a one-liner returning
AppConfig.Galleries; httpapi.Client.GallerySearch decodes straight into
[]gallery.Metadata).

All tests green with -race.

* refactor(assistant): extract REST route paths into named constants

httpapi.Client had 18 bare-string path sites scattered across methods.
Pull them into pkg/mcp/localaitools/httpapi/routes.go: static paths as
package-private constants, dynamic paths as small builders that handle
url.PathEscape on segment values.

No behaviour change. Drops the now-unused net/url import from client.go
since path escaping moved into routes.go alongside the path it applies to.

Local-only by design: the server-side registrations in
core/http/routes/localai.go remain bare strings. Sharing constants across
the pkg/ ↔ core/ boundary would invert the layering today; the existing
Tool↔REST drift-detector in coverage_test.go is the safety net for that
direction.

- LOCALAI_ASSISTANT_BOOTSTRAP_MODEL / --localai-assistant-bootstrap-model
  and the bootstrap_default_model tool were removed — admins pick a model
  from the existing selector instead, no env-var configuration required.
- The shipped tool catalog includes import_model_uri but didn't appear in
  the doc; bootstrap_default_model appeared but no longer exists.
- The Settings → LocalAI Assistant runtime toggle wasn't mentioned as the
  preferred way to disable without restart.

3db60b57e6 fix(realtime): consume ChatDeltas when C++ autoparser clears Response (#9538)
The llama.cpp C++-side chat autoparser clears Reply.Message and delivers
parsed content/reasoning/tool-calls via Reply.chat_deltas. chat.go handles
this (non-SSE path uses ToolCallsFromChatDeltas/ContentFromChatDeltas/
ReasoningFromChatDeltas), but realtime.go only read pred.Response, so any
model routed through the autoparser (Qwen2.5/3 and friends) produced a
silent reply: backend emitted N tokens, the session surface saw zero.

Mirror the non-SSE chat path in realtime's triggerResponse: when deltas
carry tool calls or content, use them directly; otherwise fall back to
the existing raw-text parsing.

7d8c1d5e45 fix(streaming): dedupe content, recover reasoning, unique tool_call IDs in deferred flush (#9470)
* fix(streaming): dedupe content, recover reasoning, unique tool IDs

When tool calls are discovered only during final parsing (after the
streaming token callback returns), processTools' default switch branch
used to emit the full accumulated content alongside the tool_call args
chunk. Clients that accumulate delta.content per the OpenAI streaming
contract end up showing every narration line twice. Three related bugs
in the same flush path:

1. Content duplication: the args chunk carried Content:textContentToReturn
   even though the text had already been streamed token-by-token via
   the token callback, so delta.content was both the running total and
   bundled with tool_calls in one delta (two spec violations).
2. Reasoning drop: when the C++ autoparser surfaces reasoning only as
   a final aggregate (no incremental tokens), the callback never emits
   it and the flush branch didn't either, silently losing it.
3. tool_call ID collision: empty ss.ID fell back to the request id, so
   multiple empty-ID calls in the same turn all shared the same id,
   breaking tool_result matching by tool_call_id.

Extracted the block into buildDeferredToolCallChunks (pure function,
unit-testable) and added 19 Ginkgo specs covering streamed vs.
not-streamed content/reasoning, single vs. multi call, and
incremental-vs-deferred emission. Every case asserts the invariant
that no delta carries both non-empty Content/Reasoning and non-empty
ToolCalls.

Fix summary:
- emit reasoning in its own leading chunk when !reasoningAlreadyStreamed
- emit role+content in their own chunks when !contentAlreadyStreamed
- drop Content from the tool_call args chunk
- fallback to fmt.Sprintf("%s-%d", id, i) for empty ss.ID so calls stay
  uniquely addressable

Reproduced live against qwen3.6-35b-a3b-apex served by LocalAI with
the C++ autoparser; the full-content replay chunk that preceded each
tool_calls block is gone after the fix.

* fix(streaming): dedupe reasoning in the noActionToRun final chunk

extractor.Reasoning() returns only the Go-side extractor's lastReasoning
accumulator (pkg/reasoning/extractor.go:129). ChatDelta reasoning
coming through ProcessChatDeltaReasoning lives in a separate
accumulator (cdLastStrippedReasoning) that Reasoning() does not
expose. The "reasoning != \"\" && extractor.Reasoning() == \"\"" guard
therefore fires exactly when the autoparser streamed reasoning
incrementally via the callback — producing a duplicate final delivery.

Replace both guard sites in the noActionToRun branch with the
sentReasoning flag introduced in the previous commit. Extract the
closing-chunk logic into buildNoActionFinalChunks so the refactor is
testable; the helper mirrors buildDeferredToolCallChunks.

Add Ginkgo coverage for both the content-streamed and
content-not-streamed paths: reasoning is dropped when it was streamed,
delivered once when it arrived only as a final aggregate, and omitted
when empty. Metadata invariants carried over from the sibling helper.

* fix(streaming): detect noActionToRun anywhere in functionResults

The previous condition only looked at functionResults[0].Name, which
misbehaved when a real tool call followed a noAction sentinel — the
noAction shadowed the real call and the whole turn was treated as a
question to answer, silently dropping the tool call. The mirror case,
[realCall, noActionCall], fell into the default branch and emitted the
noAction entry as if it were a real tool_call.

Replace with hasRealCall, which scans the slice and returns true as
soon as it finds a non-noAction entry. noActionToRun now matches the
semantic intent: "every entry is the noAction sentinel (or the slice
is empty)".

Note: this does not change incremental emission, where noAction
entries may still be forwarded as tool_call chunks by the XML/JSON
iterative parsers. That is a separate layer (functions.Parse*) and
addressing it requires threading noAction through the parser APIs —
out of scope for this change.

7809c5f5d0 fix(vision): propagate mtmd media marker from backend via ModelMetadata (#9412)
Upstream llama.cpp (PR #21962) switched the server-side mtmd media
marker to a random per-server string and removed the legacy
"<__media__>" backward-compat replacement in mtmd_tokenizer. The
Go layer still emitted the hardcoded "<__media__>", so on the
non-tokenizer-template path the prompt arrived with a marker mtmd
did not recognize and tokenization failed with "number of bitmaps
(1) does not match number of markers (0)".

Report the active media marker via ModelMetadataResponse.media_marker
and substitute the sentinel "<__media__>" with it right before the
gRPC call, after the backend has been loaded and probed. Also skip
the Go-side multimodal templating entirely when UseTokenizerTemplate
is true — llama.cpp's oaicompat_chat_params_parse already injects its
own marker and StringContent is unused in that path. Backends that do
not expose the field keep the legacy "<__media__>" behavior.

e1a6010874 fix(streaming): deduplicate tool call emissions during streaming (#9292)
The Go-side incremental JSON parser was emitting the same tool call on
every streaming token because it lacked the len > lastEmittedCount guard
that the XML parser had. On top of that, the post-streaming default:
case re-emitted all tool calls from index 0, duplicating everything.

This produced duplicate delta.tool_calls events causing clients to
accumulate arguments as "{args}{args}" — invalid JSON.

Fixes:
- JSON incremental parser: add len(jsonResults) > lastEmittedCount guard
  and loop from lastEmittedCount (matching the XML parser pattern)
- Post-streaming default: case: skip i < lastEmittedCount entries that
  were already emitted during streaming
- JSON parser: use blocking channel send (matching XML parser behavior)

13a6ed709c fix: thinking models with tools returning empty content (reasoning-only retry loop) (#9290)
When clients like Nextcloud or Home Assistant send requests with tools
to thinking models (e.g. Gemma 4 with <|channel>thought tags), the
response was empty despite the backend producing valid content.

Root cause: the C++ autoparser puts clean content in both the raw
Response and ChatDeltas. The Go-side PrependThinkingTokenIfNeeded
then prepends the thinking start token to the already-clean content,
causing ExtractReasoning to classify the entire response as unclosed
reasoning. This made cbRawResult empty, triggering a retry loop that
never succeeds.

Two fixes:
- inference.go: check ChatDeltas for content/tool_calls regardless of
  whether Response is empty, so skipCallerRetry fires correctly
- chat.go: when ChatDeltas have content but no tool calls, use that
  content directly instead of falling back to the empty cbRawResult

53deeb1107 fix(reasoning): suppress partial tag tokens during autoparser warm-up
The C++ PEG parser needs a few tokens to identify the reasoning format
(e.g. "<|channel>thought\n" for Gemma 4). During this warm-up, the gRPC
layer was sending raw partial tag tokens to Go, which leaked into the
reasoning field.

- Clear reply.message in gRPC when autoparser is active but has no diffs
  yet, matching llama.cpp server behavior of only emitting classified output
- Prefer C++ autoparser chat deltas for reasoning/content in all streaming
  paths, falling back to Go-side extraction for backends without autoparser
  (e.g. vLLM)
- Override non-streaming no-tools result with chat delta content when available
- Guard PrependThinkingTokenIfNeeded against partial tag prefixes during
  streaming accumulation
- Reorder default thinking tokens so <|channel>thought is checked before
  <|think|> (Gemma 4 templates contain both)

00fcf6936c fix: implement encoding_format=base64 for embeddings endpoint (#9135)
The OpenAI Node.js SDK v4+ sends encoding_format=base64 by default.
LocalAI previously ignored this parameter and always returned a float
JSON array, causing a silent data corruption bug in any Node.js client
(AnythingLLM Desktop, LangChain.js, LlamaIndex.TS, …):

  // What the client does when it expects base64 but receives a float array:
  Buffer.from(floatArray, 'base64')

Node.js treats a non-string first argument as a byte array — each
float32 value is truncated to a single byte — and Float32Array then
reads those bytes as floats, yielding dims/4 values.  Vector databases
(Qdrant, pgvector, …) then create collections with the wrong dimension,
causing all similarity searches to fail silently.

  e.g. granite-embedding-107m (384 dims) → 96 stored in Qdrant
       jina-embeddings-v3      (1024 dims) → 256 stored in Qdrant

Changes:
- core/schema/prediction.go: add EncodingFormat string field to
  PredictionOptions so the request parameter is parsed and available
  throughout the request pipeline
- core/schema/openai.go: add EmbeddingBase64 string field to Item;
  add MarshalJSON so the "embedding" JSON key emits either []float32
  or a base64 string depending on which field is populated — all other
  Item consumers (image, video endpoints) are unaffected
- core/http/endpoints/openai/embeddings.go: add floatsToBase64()
  which packs a float32 slice as little-endian bytes and base64-encodes
  it; add embeddingItem() helper; both InputToken and InputStrings loops
  now honour encoding_format=base64

5a67b5d73c Fix image upload processing and img2img pipeline in diffusers backend (#8879)
* fix: add missing bufio.Flush in processImageFile

The processImageFile function writes decoded image data (from base64
or URL download) through a bufio.NewWriter but never calls Flush()
before closing the underlying file. Since bufio's default buffer is
4096 bytes, small images produce 0-byte files and large images are
truncated — causing PIL to fail with "cannot identify image file".

This breaks all image input paths: file, files, and ref_images
parameters in /v1/images/generations, making img2img, inpainting,
and reference image features non-functional.

Signed-off-by: Attila Györffy <attila+git@attilagyorffy.com>

* fix: merge options into kwargs in diffusers GenerateImage

The GenerateImage method builds a local `options` dict containing the
source image (PIL), negative_prompt, and num_inference_steps, but
never merges it into `kwargs` before calling self.pipe(**kwargs).
This causes img2img to fail with "Input is in incorrect format"
because the pipeline never receives the image parameter.

Signed-off-by: Attila Györffy <attila+git@attilagyorffy.com>

* test: add unit test for processImageFile base64 decoding

Verifies that a base64-encoded PNG survives the write path
(encode → decode → bufio.Write → Flush → file on disk) with
byte-for-byte fidelity. The test image is small enough to fit
entirely in bufio's 4096-byte buffer, which is the exact scenario
where the missing Flush() produced a 0-byte file.

Also tests that invalid base64 input is handled gracefully.

* test: verify GenerateImage merges options into pipeline kwargs

Mocks the diffusers pipeline and calls GenerateImage with a source

5195062e12 fix(realtime): Include noAction function in prompt template and handle tool_choice (#8372)
The realtime endpoint was not passing the noAction "answer" function to the
model in the prompt template, causing the model to always call user-provided
tools even when a direct response was appropriate.

Root cause:
- User tools were added to the funcs list
- TemplateMessages() was called to generate the prompt
- noAction function was only added AFTER templating
- This meant the prompt didn't include the "answer" function, even though
  the grammar did

Fix:
- Move noAction function creation before TemplateMessages() call so it's
  included in both the prompt and grammar
- Add proper tool_choice parameter handling to support "auto", "required",
  "none", and specific function selection
- Match behavior of the standard chat endpoint
