Ettore Di Giacinto 644481fffb feat(vllm-cpp): unify decision pipeline through Score RPC with vllm_decide ABI v29
Replace the model-specific SystemOne gRPC approach with a generic Score
RPC extension. The pre-existing Score RPC (previously unused by any
backend) now carries question_type and response_json fields:

- question_type="systemone" routes kev/laya decision-pipeline requests
  through the unified vllm_decide C ABI (v29), returning the full
  response JSON in response_json.
- question_type empty routes cua-s1-forms candidate scoring through the
  same vllm_decide ABI, returning CandidateScore probabilities.

The vllm-cpp backend's Score() method calls vllm_decide and dispatches
by architecture internally. The /v1/systemone HTTP endpoint checks
whether the model's backend supports Score; if so, it forwards the raw
request JSON and returns the backend response as-is. Other backends
fall through to the existing NER-based path.

This mirrors the vllm.cpp C ABI refactor (PR #3301) that replaced
vllm_systemone + vllm_score with a single vllm_decide function. The
purego bindings bump abiVersion from 27 to 29 and resolve vllm_decide
and vllm_decide_free symbols.

Also fixes validModelPath to accept cua-s1-forms.json and
rl_agent_config.json alongside config.json, matching the engine's
model_loader.cpp config-filename ordering.

mudler-agentandEttore Di Giacinto 543fb4bd24 fix(gallery): verification follow-ups for oci:// galleries (#12243)
* fix(gallery): verification follow-ups for oci:// galleries

Follow-ups from the post-merge review of #12238 and #12239.

Only a policy decision is a refusal now. cosignverify wraps
ErrPolicyRejected around a failed signature check, an identity or
source-repository mismatch, a not_before cutoff and a missing or
unparseable bundle. A TUF, registry or network failure during
verification, or a timeout, is an outage: the gallery falls back to the
copy verified under the current policy, as it does when the registry is
down.

An oci:// gallery with a verification block, or any oci:// gallery under
strict integrity, is no longer answered by an https://, github: or
file:// mirror. Such a mirror is ignored with a warning, because nothing
can check its signature. The index of an HTTP gallery, whose policy only
covers its backend images, is cached under the URL-only name again, so no
unchecked body is stored under a policy-keyed name.

The in-memory index cache key now includes the policy. After a runtime
policy change the index is fetched again, and entries with a relative url
install again.

The registry digest lookups after install and upgrade, and in the
upgrade check, run only for real registry references (new
URI.LooksLikeRegistryOCI), not for ollama:// or ocifile://.

The refusal message names strict integrity when that is the cause, and
the gallery name is no longer repeated.

Specs pin the URL-only cache name for galleries without a policy, a fixed
key for a fixed policy, and that every GalleryVerification field changes
the key. The docs describe refusal, outage, mirrors and strict integrity.

* fix(gallery): reset listings on gallery changes, classify referrer outages

Review follow-ups for this PR.

The React UI lists from AvailableGalleryModelsCached, which is keyed by
nothing. A gallery change through the settings API or a
runtime_settings.json edit now drops that listing when the model or
backend gallery configuration differs. Before, the UI kept the old list,
with local paths into the old policy's tree, until the next background
refresh, or for good when the new policy refused the gallery.

In cosignverify, a referrer the registry fails to serve now makes the
lookup an outage whatever other referrers failed and in any order, since
the unread one may be the valid signature. An invalid policy (Validate in
NewVerifier, an unparseable not_before) is ErrPolicyRejected, because no
fetch can make it usable.

The docs say that only an oci:// gallery with a verification block skips
non-OCI mirrors, and list an unusable policy as a refusal.

21c5495a99 feat(vllm-cpp): add GLiNER2.5 NER via TokenClassify (#12140)
* feat(vllm-cpp): add GLiNER2.5 NER via TokenClassify

Wire the vllm-cpp backend to the C ABI NER surface (vllm_gliner_ner,
ABI v27) so LocalAI can serve zero-shot named entity recognition through
the existing TokenClassify gRPC method.

backend.go: TokenClassify method on *VllmCpp calls vllm_gliner_ner with
the text and labels, copies the C-owned entity array into protobuf
TokenClassifyEntity messages, and frees the result.

govllmcpp.go: cNerEntity and cNerResult Go POD mirrors matching the C
structs; vllmGlinerNer and vllmNerResultFree purego bindings; abiVersion
bumped 26 -> 27.

options.go: ner_labels, ner_threshold, ner_max_width parsed from
engine_args.

pkg/grpc: ClassifyModel interface and TokenClassify server handler
(follows the Embedding locking pattern).

core/config: vllm-cpp backend declares MethodTokenClassify and
UsecaseTokenClassify.

* feat(vllm-cpp): add kev-compatible SystemOne API endpoints

Add POST /v1/systemone, /v1/systemone/permute, and
/v1/systemone/separate to LocalAI, mirroring the kev project's
structured-extraction API. Each endpoint runs zero-shot NER over the
rendered state text and builds kev-compatible answers for three question
types: noul (binary entity presence), choice (pick one option), and
score (pick one level).

The TokenClassifyRequest proto gains a `repeated string labels` field so
each question can supply its own labels at inference time, and
TokenClassifier gains TokenClassifyWithLabels for per-call label
selection. The vllm-cpp backend uses request labels when non-empty,
falling back to configured ner_labels then the built-in defaults.

Helpers (renderState, softmax, choiceConfidence, scoreConfidence, r2)
are ported from kev/api.py and mirrored in vllm.cpp's api_server.cpp so
both servers produce the same answer shape.

* fix(vllm-cpp): use instruction text as NER label in SystemOne handler

The SystemOne handler was passing question IDs as NER labels for noul
questions and bare key names for choice questions, so the model never
matched any entities. Port the label mapping from vllm.cpp's
ParseSystemOneBody:

- noul: use the rendered instructions field (with instr alias) as the
  NER label, not the question ID
- choice: use optionText(name, desc) — "name: description" or "name"
  when the description is null/empty — not the bare key
- score: already correct (rendered criteria text)
- permute: shuffle indices and build parallel key/label arrays so the
  NER call uses the optionText labels while the response is keyed by
  the original option names

Also add the instructions field to the SystemOneQuestion schema struct
(accepted alongside the instr backward-compat alias).

Verified end-to-end against the real GLiNER2.5 model: noul questions
now find "Apple Inc. is" (organization, 0.999) and "Tim Cook is"
(person, 0.852) where they previously returned zero entities.

636c43baa5 fix(openai): return HTTP errors for pre-stream failures and report per-slot context (#12204)
* fix(capabilities): report the per-request context with split KV slots

With parallel slots and kv_unified:false, llama.cpp gives each slot
n_ctx/n_parallel, padded up to a multiple of 256. /models/capabilities
still reported the full n_ctx. A client that budgets a request against
context_size then overflows at a fraction of it.

EffectiveRequestContextSize returns the per-slot size in that case and
the full context otherwise. With the unified KV cache, the grpc-server
default, one request may use all of n_ctx. The capabilities endpoint
and the router's prompt trimmer now use it.

* fix(openai): return an HTTP error when a stream fails before any chunk

A streamed chat request set the SSE headers, then waited for the
backend. When the backend failed before the first token, LocalAI sent
a 200 with a `data: {"error":...}` chunk and [DONE]. Clients that do
not parse error chunks saw an empty reply. cogito's LocalAI client was
one of them: nib users got "streaming decision produced no content"
instead of the context overflow that caused it.

Nothing has been written at that point, so the handler now returns the
error as a normal HTTP response. A failure after the first chunk keeps
the in-stream error chunk.

A prompt that exceeds the context is now a 400 on both paths, as in
the OpenAI API and llama-server, and no longer a 500. The message is
kept whole, because clients read the token counts from it.

localai-org-maint-botandEttore Di Giacinto c0b7e64973 feat(ui): show running models and host gauges on single-node installs (#12189)
On a single-node install nothing in Operate listed the models loaded on
this machine or let an admin stop one. The System page that did was
retired in #11548, and its replacements (the Nodes workbench) only work
in distributed mode. The Nodes page also mis-detected single-node mode:
the cluster routes are not registered there, so /api/nodes answers 404,
but only 503 was treated as "distributed off", which sent every
single-node install to the empty worker-registration card. The rail hid
the entry anyway.

Nodes route on a single node becomes "This machine":
- the Nodes page's VRAM / RAM / CPU / models-disk gauges, fed from this
  host by mapping /api/resources onto the worker heartbeat fields
- a memory bar splitting host RAM by running model
- a running-models table (backend, RSS, CPU share, uptime, PID) with
  search, sorting, logs and a confirmed Stop
- the distributed setup behind an "Add machines" button

The Operate overview gains a "Running now" preview (heaviest five, with
Stop) on single node and a pointer to Nodes > Running models on a
cluster. The rail shows "This machine" in Runtime with a running count.

Backend, additive only:
- /system: each loaded model carries a `process` block (pid, rss_bytes,
  memory_percent, cpu_percent, started_at). A sampler keeps one gopsutil
  handle per PID so CPU is the share since the previous poll rather than
  the lifetime average; it is omitted on the first reading.
- /api/resources: host `cpu` and models-path `disk`, the same readings
  workers send in their heartbeat.

Also fixes the fleet tables widening the page on phones: the headers'
absolutely positioned sr-only labels escaped the scroll wrapper.

turn against a model that really serves 100k.

Resolve the alias and report the target's capabilities, modalities and
context_size under the alias's id. A dangling or chained alias now

configured context_size or falls back to DefaultContextSize (4096) —
the same number the backend itself runs with. It is omitempty so a
loose file with no config surfaces 0 (unknown) rather than a misleading
default, and existing clients that don't know the field see no change.

mudler's LocalAI [bot]andEttore Di Giacinto 80e3240f2d feat(distributed): key scheduling rules by a model alias (#11771)
Node placement and replica rules could only name a model, so an operator
who pinned "llama3" to the GPU tier had to rewrite the rule whenever a
different model took over that job. An alias already gives a stable name
for whichever model serves it, and a rule on that name makes it a
deployment slot: repoint the alias and the placement follows.

A rule keeps the name the operator chose. Reads resolve that name through
the config loader to the model the rule governs, so the reconciler counts,
schedules and trims replicas of the target, and the router finds an
alias-keyed rule from the target it is already routing. An alias that
resolves to nothing governs nothing loadable, so the reconciler skips it
and the write paths refuse it.

A replica is shared by every name that resolves to it, so only one rule
can decide where it runs. The REST and MCP write paths reject a rule whose
target another rule already governs. A pair that arrives some other way,
such as a seed file or an alias repointed onto a model that already has a
rule, resolves in favour of the rule named after the model itself and then
the oldest, and the rest are listed as shadowed.

The eviction guard is the exception: it matches rules to replicas in raw
SQL inside a locking transaction and cannot resolve an alias. It reads a
stored target that the reconciler refreshes each tick, and falls back to
the rule's own name when that target is empty.

mudler's LocalAI [bot]andEttore Di Giacinto 29899cd1e0 fix(ui): size model fit against the cluster and move node labels into the selector (#11765)
* fix(ui): move node labels into the scheduling selector field

The scheduling page kept a node-label browser open above the rules
whether or not anyone was writing one, while the field that actually
needs labels, the rule's node selector, was two bare text inputs with no
hint of what the cluster reports.

The browser is gone. The selector's key input now completes against the
label keys the cluster uses, and the value input offers only the values
that key takes. The roster already loads for the page, so the
suggestions cost no request, and a roster that fails to load costs the
admin the hints and nothing else.

Suggestions stay suggestions: a key no node reports yet still commits as
typed, which is how an admin writes a rule before labelling the nodes
for it.

* fix(distributed): size model fit against the cluster, not the frontend

The models page asked the frontend how much memory a model may occupy.
In distributed mode the frontend is usually a GPU-less pod while every
model runs on a worker, so a fleet of GPU nodes was told it could only
run the smallest CPU build. The variant picker's fits flag and its
auto-selection came from the same place, as did the hardware
recommendations.

The registry now reports the largest single healthy backend node. The
largest node, not the fleet total: a model loads into one node, so four
16GB workers are not a home for a 40GB model. An operator-set VRAM
budget caps a node's contribution, because the scheduler refuses a load
above that ceiling anyway, and a GPU node beats a CPU node holding more
system RAM.

GET /api/resources and GET /api/models carry this as an additional
cluster object. Their aggregate and ram fields keep reporting the
frontend's own hardware, which is what the resource monitor shows.
Variant selection judges backends against the union of the capabilities
present in the cluster, the way backend discovery already did.

Every path degrades to the local host: no cluster object in single-node
mode, and none when the registry cannot be read, so a hiccup narrows the
answer back to single-node behaviour rather than marking the whole
catalog too large.

The verdicts now name the node they belong to, since a model fits
somewhere or nowhere.

Ettore Di Giacinto 1dc3aeef87 fix(distributed): resolve config revisions through one entry point
A model's revision is published by administration and checked against on
every inference request. Those were computed by separate code: the
request path resolves through the loader, while each publisher hashed
whatever ModelConfig it happened to hold. By then SetDefaults had folded
in the GGUF guess and app-level options, so the published value was one
no request would ever carry and the model became unroutable until the
row was deleted by hand.

Fixing the publishers one at a time did not hold. Three rounds each
found another: the startup resync, then a saved edit and a toggle, then
a rename and the peer-change path.

ModelConfigLoader.RevisionFor is now the only way to obtain a revision,
and the raw hash is unexported, so a caller outside this package cannot
hash a config it holds. A publisher and a request agree by construction
rather than by two implementations happening to match.

The request path no longer falls back to hashing its merged config
either: an unstamped config is routed without a revision rather than
with a wrong one.

* test: drop the static network lint in favour of real isolation

The offline test suite already prevents tests from reaching the network
twice over: run-test-linux-offline.sh puts the test process in a cgroup
and REJECTs egress outside the private ranges, and HardenedTransport
installs testnetwork.LocalGuard to refuse dials that resolve to a public
address. Both fail the test with a precise error at the moment of the
dial.

test-network-lint.sh added neither. Its diff stage defaulted to a HEAD
base, so on a clean checkout it compared the tree against itself and
inspected nothing; the branch's own commits were never examined. It only
produced output when an earlier job step dirtied the tree, and then it
matched a bare https?:// against whatever changed. make react-ui runs
npm install rather than npm ci, so CI rewrote
core/http/react-ui/package-lock.json and the lint reported an npm
registry URL as forbidden test network access:

  +      "resolved": "https://registry.npmjs.org/hono/-/hono-4.12.25.tgz",

Its fingerprint stage was self-defeating in a quieter way: hashing the
whole tree's network-mechanism inventory meant every rebase onto a master
that touched any _test.go needed a manual baseline bump, so the check
mostly caught its own staleness.

Remove the script, its make target and the two prerequisite edges, along
with the test-network: fixture markers that existed only to suppress it.
The isolation itself is untouched.

Cherry-picked from 15a37b0ac on the remote branch. The offline bundle lives

The other half of 15a37b0ac moved test-network-lint out of the `test` and
`test-coverage` prerequisite lists into a recipe line, so parallel make could
not fingerprint the tree while generated fixtures were still changing. That
is dropped: the preceding commit removes the lint entirely, and the race it
worked around is one more reason a whole-tree fingerprint was the wrong
mechanism.

Richard Palethorpe d10374f849 feat(router): make KNN a first-class classifier with a persisted, curated corpus (#10652)
* feat(router): make KNN a first-class classifier with a persisted, curated corpus

Add `classifier: knn` — similarity-weighted voting over labelled
example prompts. Unlike score/colbert it needs no classifier model:
label knowledge lives in a corpus seeded and curated through the
admin API, so routing decisions are deterministic, auditable, and
grounded in graded experience rather than a model's opinion.

Epistemic gate: corpus entries below knn.similarity_threshold cannot
vote; when none clears it the classifier activates no labels and the
router uses the fallback — a prompt unlike all labelled experience is
treated as undecidable, not guessed. Decisions record
nearest_similarity (also on fallback rows) so admins can see how far
the nearest labelled experience was; the Routing tab explains
out-of-corpus fallbacks and shows per-label corpus counts.

Persistence: one JSONL file per router under
<data path>/router-corpus (text, labels, vector, embedder
fingerprint). The file is the source of truth; the local-store index
is rebuilt from it at classifier build time and stays a pure
in-memory index. Entries recorded under a different embedding model
re-embed on load. Also corrects the docs' false claim that
local-store collections persist — the embedding cache never survived
restarts (and still doesn't); the corpus does.

Corpus input is API-only by design (entries may contain example user
content): POST /api/router/{name}/corpus seeds (labels validated
against declared policies, embedded server-side, indexed
immediately), GET .../corpus/stats inspects — label counts only,
entry texts are never returned by any surface — DELETE .../corpus
wipes. Admin-gated like the sibling router endpoints, and exposed as
MCP tools (seed_router_corpus / get_router_corpus_stats /
clear_router_corpus) in both the httpapi and inproc clients with
coverage-test route mappings.

Plumbing: VectorStore gains SearchK (top-K was hardcoded to 1);
local-store gets InsertBatch/Delete as optional fast paths;
RouterConfig gains a knn block (embedding_model, k,
similarity_threshold, vote_threshold, store_name) with meta-registry
fields; the classifier dropdown now offers knn and the
previously-missing colbert; embedding_cache is ignored (with a
warning) for knn — it IS an embedding-KNN lookup; the stale
/api/instructions intelligent-routing entry is rewritten (it
described a classifier that no longer exists); swagger regenerated.

Tests: KNN vote/gate specs with hand-computed vote shares, corpus
manager suite (restart reload without re-embedding, fingerprint
re-embed, dedupe, hostile store names), middleware specs (corpus
routing, gate fallback, config validation, cache-wrap refusal),
corpus endpoint specs pinning the texts-never-returned contract, MCP
catalog + route-mapping gates, and a Playwright spec for corpus
stats and the out-of-corpus decision detail.

* feat(router): name consulted corpus neighbours in knn decisions

Every knn decision (decision log rows and the /api/router/decide
response) now carries neighbors: the K retrieved corpus entries by
descending similarity - including ones below the epistemic gate, which
is what makes fallback decisions diagnosable - each as {id, similarity,
labels}. The id is the entry's content hash (first 8 bytes of the
SHA-256 of its text, hex): stable across reseeds and re-embeds, and
text-free, so an external platform that seeded the corpus can recompute
text->id on its own copy and bucket decisions by corpus region (per-
region reliability accounting) without corpus text ever leaving the
server. A corrupt index payload surfaces as an id-less neighbour at a
real similarity instead of disappearing.

changes on the API surface.

Reuse/altitude:
- RouterKNNConfig.ResolvedStoreName is now the single source of the
  router-corpus-<name> default (was hand-derived in four files).
- corpus.ResolveKNNRouter + corpus.Seed carry the shared model
  resolution and seed validation; the REST endpoints and the assistant
  MCP client are thin transport adapters over them, with sentinel
  errors mapped to HTTP statuses at the echo boundary.
- middleware.NewClassifierDeps assembles the classifier dependency set
  once for all five entry points (OpenAI, Anthropic, realtime, decide,
  corpus) instead of five hand-copied literals.
- router.AllClassifiers feeds both the status endpoint and the
  unknown-classifier error, ending the classifier-list drift.
- Per-classifier requirements moved out of validateRouterPolicies into
  their buildClassifier arms; the knn arm owns its embedding_cache
  opt-out instead of a name-check in the shared wrap tail.
- adminOnly replaces four inline copies of the admin gate in the
  middleware routes.
- localVectorStore.Search delegates to SearchK (identical traces).

Efficiency:
- Manager.Add embeds outside the manager mutex and appends to the
  JSONL file (O(new) instead of O(corpus) rewrite); a torn tail from a
  crash mid-append is tolerated on read and repaired on next write.
- Stats memoises per store keyed on the file's stat fingerprint and no
  longer takes the manager mutex, so the 5s status poll stops parsing
  vector-laden JSONL and stops blocking behind seeds.
- KNN Classify decodes each neighbour payload once (was twice) and
  builds refs and votes in a single pass with one fallback return.
- Corpus file writes fsync before rename/close.
- The corpus manager is built eagerly in newApplication (sync.Once
  dropped); test helper dead branch removed.

A model config defaulting to decayed_mean pooling carries
pooling_half_life_tokens; a request overriding the scheme to mean/last

validation rejected the pair the server itself had assembled. Zero the
inherited half-life when the overridden scheme is not decayed_mean; a
request that explicitly pairs a half-life with a non-decayed scheme
still 400s.

88edd7fc7f fix(distributed): run cold model loads as durable jobs instead of holding the advisory lock (#11514)
* fix(advisorylock): set statement_timeout alongside lock_timeout

WithLockCtx already overrides a deployment-wide lock_timeout on its
dedicated connection so a blocking pg_advisory_lock() waits its turn
instead of failing with 55P03. statement_timeout aborts that exact same
statement independently, with SQLSTATE 57014, and was not overridden.

Production roles commonly carry statement_timeout=60s. Any guarded
section longer than that (a cold model load stages for tens of minutes)
therefore killed every concurrent waiter:

  advisorylock: acquiring lock 9003261067483446873: ERROR: canceling
  statement due to statement timeout (SQLSTATE 57014)

Derive it from the same context budget as lock_timeout, with a matching
RESET so the pooled connection is returned clean.

Assisted-by: Claude Opus 5 [claude-code]

* feat(distributed): add ModelLoadJob, the durable cold-load record

A cold load in distributed mode is a long-running background job, but it
was modelled as a synchronous side effect of an inference request: the
whole of it (backend install, multi-GB staging, checkpoint load) ran
inside the per-model advisory lock. Loading a 35.7 GB GGUF held that lock
for ~20 minutes, so every concurrent request for the same model blocked
on pg_advisory_lock and died at the role's 60s statement_timeout.

Introduce the row that lets the lock shrink to a decision. Exactly one
ModelLoadJob may be active per tracking key; that uniqueness — not the
lifetime of a lock — is what de-duplicates concurrent loaders across
replicas. ClaimLoadJob does its read-then-write under the advisory lock
and nothing else: no network, file or gRPC I/O inside the guarded
section, so a claim costs milliseconds no matter how long the resulting
load takes.

LastProgress is a heartbeat rather than a byte counter. A checkpoint load
legitimately moves zero bytes for many minutes, so a reaper keyed on byte
movement would reclaim a healthy job mid-load; byte progress stays the
concern of load_deadline.go. A job whose heartbeat stops for longer than
the orphan window is reclaimable, so a replica killed mid-load cannot
wedge a model permanently.

Failed jobs keep their row for a short grace so an immediately-following
request reports the real cause instead of silently starting a fresh load
of a model that just failed.

No caller yet — the router moves onto this in the next commit.

* refactor(distributed): run cold loads as jobs, outside the advisory lock

Route wrapped the entire cold load — node selection, backend install,
multi-GB staging and the remote LoadModel — in the per-model advisory
lock. The lock's job is to de-duplicate concurrent loaders, a decision
that takes milliseconds; holding it for the tens of minutes the resulting
work takes is what turned a dedup mechanism into a cluster-wide outage
for that model.

Split it into a claim and a run. The claim is the only thing left inside
the lock. The run is a background job owned by the claiming replica and
bounded by the same progress-extended deadline as before; every other
request for that model — local or on another replica — attaches as a
waiter and is served the moment the model is ready, with no duplicate
load and no lock contention.

Waiters share one broadcast rather than an ordered queue: they all want
the identical outcome, so ordering them would add fairness machinery that
changes no result. The local channel wakes same-replica waiters instantly
and a 2s DB poll is the authority, because a waiter on another replica
has no channel to close. On wake a waiter re-runs the warm path rather
than trusting the signal — the model may have been evicted in between.

A waiter whose client disconnects returns immediately and the job keeps
running; it belongs to the job record, not to the request. A failure is
recorded on the row so every waiter reports the real cause, and the row
survives briefly so the next request does not read "no job" as "not
loading" and start a duplicate load of a model that just failed.

The runner heartbeats the row on a fixed interval whether or not bytes
are moving, which is what keeps a legitimately silent checkpoint load
from being reclaimed as an orphan. Phase (installing/staging/loading) and
placement ride to the heartbeat on the context, the same seam
load_deadline.go already uses, so single-host paths are untouched.

Non-distributed mode (no DB) keeps the inline load exactly as it was.

* feat(distributed): bound the wait for a loading model and answer with progress

A request whose model is cold-loading now attaches to the running job and
is served the moment the model is ready. That wait has to be bounded: a
held HTTP request cannot survive real infrastructure, and an ingress or LB
idle timeout kills a twenty-minute request regardless of what LocalAI
does.

New LOCALAI_MODEL_LOAD_WAIT (default 60s) bounds the CALLER, never the
load — the job keeps running either way. On expiry the request gets 503
with Retry-After and a structured body naming the model, the node, the
phase, byte progress and an ETA. The `error` envelope keeps OpenAI
clients working; `loading` is additive so they ignore it.

The ETA comes from the job's own observed rate and is omitted rather than
guessed until enough bytes have moved for that rate to mean anything: a
confidently wrong ETA on a twenty-minute wait is worse than none.
Retry-After is that ETA when known, clamped to [5s, 300s], and the wait
budget otherwise.

LOCALAI_MODEL_LOAD_WAIT=0 waits unbounded, for deployments with no proxy
in front. Zero in the config struct still means "unset, use the default",
so the CLI records the operator's zero as ModelLoadWaitUnbounded rather
than losing the distinction.

The distributed branch of ModelLoader.loadModel wrapped the router's
error with %s, which flattened it to a string. Use %w: the typed error is
what the HTTP layer keys the 503 off.

Assisted-by: Claude Opus 5 [claude-code]

* feat(api): add GET /api/models/{id}/load-status

A client that receives 503 while a model stages onto a worker needs
somewhere to poll. This returns the same `loading` object the 503 carries
— phase, node, byte progress and ETA — or 404 when no load is running.

Read-only and observability-shaped, so it is deliberately neither
admin-gated nor feature-gated: it explains a 503 the caller just
received, and hiding that behind a per-modality feature would make the
explanation for a failed image request depend on chat permissions. It
also gets no MCP tool, since there is nothing here an admin would manage
conversationally.

Registered on the surfaces from .agents/api-endpoints-and-auth.md: the
swagger block (existing `models` tag, so /api/instructions needs no new
area), the endpoint discovery maps in RegisterLocalAIRoutes, regenerated
swagger, and the distributed-mode docs page. No FLAG_* usecase is
involved, so capabilities.js is unchanged.

* feat(ui): show cold-load progress in Chat and retry when the model is ready

A chat request for a model that is still staging onto a worker now gets a
503 carrying live progress instead of an error. Render it: the composer
shows the phase (installing / staging / loading), the node, the percent
and the ETA, then polls load-status and re-sends the request the moment
the model is ready.

Reuses the staging progress idiom the page already had rather than
inventing a second one — the two sources are folded into one
loadProgress, with the load job winning because it is authoritative
across frontend replicas and knows the phase, where the staging operation
only knows about a byte transfer this replica happens to be performing.

Waiting is bounded (three send attempts, ~30 min of polling each), so a
load that never finishes still surfaces as an error rather than as a
spinner nobody questions. An aborted generation stops the polling too.

Dimitris Karakasilis 3636fcbd38 fix(realtime): keep the ICE interface allow-list working with a fixed UDP port (#11466)
LOCALAI_WEBRTC_ICE_INTERFACES was silently ignored whenever
LOCALAI_WEBRTC_UDP_PORT was set. Every interface was gathered regardless
of the allow-list, so a browser was handed the docker0/veth addresses the
setting exists to suppress, and the connection established on a good pair
and then dropped when consent checks failed on the unreachable ones.

Two things combine to cause it. A mux built over a wildcard socket makes
pion derive its host candidates by enumerating interfaces itself, with a
nil filter and loopback included. Independently, the muxed gathering path
in pion/ice never consults SetInterfaceFilter, so setting it has no effect
there either.

Bind one socket per admitted interface address via NewMultiUDPMuxFromPort,
which takes the filter, instead of one wildcard socket. All the sockets
share the same port, so the firewall requirement is still a single rule.
Networks are pinned to UDP4 to match the socket family this replaces.

An allow-list that matches no address on the host now reports the
misconfiguration rather than binding nothing and leaving signaling to
succeed while no candidate is ever advertised.

Two tests: one asserts an unmatched allow-list is an error, and one gathers
against a real peer connection and asserts no address outside the allowed
interface appears (skipped on single-interface hosts).

mudler's LocalAI [bot]andEttore Di Giacinto a0f50b2af2 feat(vllm-cpp): serve MiniMax-H3 video+audio generation (#11424)
* feat(vllm-cpp): serve MiniMax-H3 video+audio generation

vllm.cpp's C ABI grew a video slice (ABI v12): a second engine handle
loaded from the MiniMax-H3 checkpoint SET, one blocking generate, and a
composed ffmpeg argv the caller execs. This wires that into LocalAI's
existing /video endpoint, so `vllm-cpp` now serves both text and video
and a clip comes back as an MP4 with a real audio track rather than a
silent render.

The video engine is a separate handle rather than a mode of the text
one because H3 is not a model directory: the DiT, the text encoder and
two VAEs are separate artifacts, and vllm.cpp has the two loaders refuse
each other's checkpoints. `Load` takes the video branch when the config
declares any of the video options; `parameters.model` is the DiT and the
rest of the set is named in `options:`.

Three details are worth calling out because getting them wrong is
expensive:

- The partition is DECLARED, not detected. The community quantisations
  strip the release metadata and the FL2VA and Ref2VA DiTs are
  byte-structurally identical, so the engine refuses to generate until
  it is told which it has. Worse, a mismatch does not fail cleanly: a
  reference passed to an FL2VA DiT renders for hours and returns a
  coloured lattice over the frame. The backend refuses that combination
  up front instead.
- ffmpeg comes from the host. libvllm writes frames plus a WAV and
  composes the mux argv, then spawns nothing - that process boundary is
  upstream's decision. The backend execs it, the same arrangement
  vibevoice-cpp uses for transcoding, and ffmpeg also converts a
  start_image upload into the binary PPM at the exact output canvas the
  engine requires.
- It is slow. Roughly 176 s per denoise step at the default 1344x768
  canvas on a 20-SM device, so the 50-step default is a multi-hour job.
  Nothing on this path imposes a deadline.

The /video endpoint no longer forces 512x512 when the request omits the
geometry. Every video backend already supplies its own default for a
zero (512x512 for stablediffusion-ggml, 1280x720 for diffusers, 832x480
for longcat-video, 1344x768 for H3), so the hardcoded value only ever
overrode the model's trained canvas with one three of the four were
never trained at.

Moving the engine pin from ABI v10 to v16 also grows the text
vllm_model_params mirror by the v14 device field and the v16 KV-sizing
knobs. LocalAI sets none of them - 0 is the pre-v14 engine byte for byte
- but the struct SIZE is part of the layout contract, so leaving them
out would have vllm_engine_load read past the allocation.

Gallery: `minimax-h3-fl2va-q4` installs the Q4_K_M FL2VA set (~40 GB
across five weight files plus the two VAE configs that carry the latent
statistics).

* fix(vllm-cpp): unbreak the Darwin build at the new engine pin

src/capi/vllm_c.cpp opens one `extern "C" {` for the whole ABI surface,
so file-local helpers declared inside it inherit C linkage. The video
slice added one that returns std::string, which Apple Clang reports as
-Wreturn-type-c-linkage and vllm.cpp's target-local -Werror turns into a
build failure. GCC and upstream Clang do not diagnose it, so only the
metal-darwin-arm64 job saw it.

Suppress it the same way this Makefile already suppresses Apple Clang's
-Wgnu-folding-constant on the Metal build. The helper is never called
across the boundary so the warning describes no hazard here, but it is a
real upstream wart: the fix belongs in vllm.cpp, hoisting the helper
above the extern "C" block, and this flag should go when a pin carrying
that fix lands.

Assisted-by: Claude:claude-opus-5

* fix(vllm-cpp): patch the engine clone instead of the warning flag

The -Wno-return-type-c-linkage added in the previous commit does nothing.
vllm_cpp_set_warnings adds `-Wall -Wextra -Werror` as PRIVATE target
options, so they land after anything CMAKE_CXX_FLAGS contributes, and
-Wall re-enables the -Wreturn-type group that -Wreturn-type-c-linkage
belongs to. The darwin job failed again on the same line, which is the
evidence: a consumer cannot wave this off from outside the engine.

Position is the only fix, so carry it as a patch against the pinned SHA,
the way longcat-video patches its own upstream. It hoists the helper
above the `extern "C" {` that gives it C linkage; it is file-local and
never called across the boundary, so nothing else moves.

`git apply` is unguarded on purpose: a patch that stops applying must
fail the clone loudly, because the alternative is a pin that silently
ships without a fix it is documented to carry. The patch header names
what retires it - a pin carrying the fix upstream, where it belongs.

Verified by applying the patch with `git apply` to the exact blob at the
pinned SHA and diffing the result against the intended file.

Assisted-by: Claude:claude-opus-5

* chore(vllm-cpp): bump the engine pin to ABI v17 and drop the vendored OrEmpty patch

The OrEmpty linkage fix this backend carried as patches/0001-* landed upstream
(mudler/vllm.cpp#195, 7534da65), so the patch has done its job. It is deleted
rather than left in place: the Makefile applies patches/*.patch unguarded and
documents that "a patch that no longer applies must FAIL the clone", so keeping
it against fixed source would break the build the moment the pin moved. Bumping
the pin and deleting the patch therefore have to be the SAME change.

Pin f921062b -> 776c56f1 (current vllm.cpp main).

That range also carries the engine's ABI v17 (vllm_server_main: the OpenAI server
published on the public surface). registerLib compares the library's
vllm_abi_version against `abiVersion` for EXACT equality, so the constant moves
16 -> 17 in the same commit or every load fails with an ABI mismatch.

The bump is safe for the layout assertions in video_test.go: diffing include/vllm.h
across the two pins shows zero struct-field changes -- v17 adds one function
declaration, the version macro and a doc comment, nothing else -- so every
unsafe.Offsetof in the video params test still holds.

Assisted-by: Claude Code:claude-opus-5 [ClaudeCode]

* chore(vllm-cpp): re-pin to pick up the VLLM_CPP_SERVER=OFF link fix

The previous pin carried vllm.cpp's ABI v17 (vllm_server_main) but not the guard
that makes it link when the server is compiled out. This backend builds libvllm
with VLLM_CPP_SERVER off, so the darwin lane failed at the dylib link with
vllm::entrypoints::openai::VllmServerMain undefined.

Fixed upstream in mudler/vllm.cpp#202: the C entry point is now guarded, so the
symbol is still exported (ABI v17 stays resolvable for dlopen) while the
no-server arm reports the missing capability instead of dragging in a translation
unit that was never compiled.

Verified upstream in BOTH arms before re-pinning: SERVER=ON builds and runs, and
SERVER=OFF configures, links, produces libvllm.so, and `nm -D` shows
vllm_server_main exported next to vllm_video_generate and vllm_transcribe.

* feat(nemo-speech-cpp): scaffold the backend and upstream build

Adds the backend skeleton and the NeMo-Speech.cpp build, pinned at
2e12e2def8a98ed06666f7ee3ca94e7193e04be4. The Go side is deliberately a stub:
it dlopens the runtime and starts the gRPC server, later work fills in the
symbol table and the model logic.

Three details of the upstream layout differ from what the plan assumed, and the
build reflects the real tree:

* The TTS C ABI ships as libnemo_speech_tts, not libnemo_speech_tts_c. Upstream
  compiles c_api.cpp straight into the implementation library and only aliases
  the nemo_speech_tts_c CMake target, so no _c object exists on disk. ASR and
  NMT do build a real _c shim.
* Shared objects land in build/bin, since upstream points
  CMAKE_LIBRARY_OUTPUT_DIRECTORY at ${CMAKE_BINARY_DIR}/bin.
* The ASR and NMT _c shims carry a DT_NEEDED on libnemo_speech_asr and
  libnemo_speech_nmt, so those are staged and packaged alongside them.
  Otherwise dlopen fails at startup.

The ggml patch step uses an order-only prerequisite. cmake writes into the
checkout and bumps its mtime past the sentinel, which would otherwise re-run
git apply over an already-patched tree and break every incremental build.

* fix(nemo-speech-cpp): make 'build' produce the package and bundle the ITN stack

Addresses the review of the scaffold commit.

backend/Dockerfile.golang runs 'make -C backend/go/$(BACKEND) build' and then
copies package/ into the final image, so 'build' has to end with a populated
package/. It only staged shared objects, which would have shipped an image with
no binary and no libraries at all. The old staging recipe is now stage-libs and
the chain is stage-libs, nemo-speech-cpp-grpc, package, build, matching every
sibling Go backend.

Text normalization was packaged incorrectly. nemo_speech_text_normalization is
STATIC but links sparrowhawk, fstfar and fst PUBLIC, so they land as DT_NEEDED
on libnemo_speech_asr.so, and they live in a project-local prefix that nothing
else provides. WITH_NORM stays ON by default on Linux, since normalization is a
wanted feature. Instead stage_libs now copies .deps/itn/lib when WITH_NORM=ON,
and package.sh bundles it.

Staging that prefix is still not enough on its own: Sparrowhawk drags in
protobuf, re2 and absl, which neither build_itn_deps.sh nor
package-system-libs.sh provides. Rather than hard-code another hand-maintained
list, package.sh now walks the DT_NEEDED entries of everything staged and copies
whatever is unresolved, skipping the core set and the GPU set that the shared
scripts already own. It fails at package time, not at first dlopen, when
something cannot be resolved. On a WITH_NORM=OFF build the closure is already
complete and it copies nothing.

Restore CGO_ENABLED=0 on the Go build to match whisper, parakeet-cpp and
omnivoice-cpp. Note that purego reaches dlopen through fakecgo, so the binary is
dynamically linked either way; what the flag changes is the NEEDED set, and
lib/ld.so routing in run.sh exists precisely because the binary is not static.

Replace the hand-rolled .patched sentinel with upstream's
scripts/apply-ggml-patches.sh. It applies the series in filename order, exits
non-zero when a patch does not apply, and detects "already applied" by comparing
the full-series tree hash rather than an mtime, so it is safe to run every time
and there is no sentinel left to go stale or to wedge the build when deleted. It
is wired as an order-only prerequisite so running it does not force a relink.

Also: correct the package.sh header, which claimed three shared objects when
there are five and none of the TTS ones carry a _c suffix; give 'make test' the

bump needs 'make purge'; and extend 'clean' to remove package/ and the ITN
libraries.

* fix(nemo-speech-cpp): make the closure guard fail closed and give CI its toolchain

Addresses the second review round.

The dependency-closure guard failed open. Its glob expands once per pass, so
each pass advanced the closure by exactly one level, and the fixed count of five
passes then fell out of the loop without checking whether anything remained. An
eight-deep chain packaged six libraries, exited zero and reported success. That
is the case the guard was written for: asr to sparrowhawk to protobuf to absl
already runs several levels deep, so a WITH_NORM build could ship missing its
deepest libraries and fail at first dlopen. The loop now runs until the staged
set stops growing, and exhausting the bound is a hard error rather than a silent
exit.

For the same reason, a build image with neither readelf nor objdump no longer
warns and skips. It cannot show the package is complete, so it refuses to ship
it. The guard is entered only when there is something to check, so an empty
package cannot trip the new error.

Dockerfile.golang installed ninja-build only in the Vulkan branch while this
Makefile runs cmake -G Ninja unconditionally, so the CPU, cuBLAS and L4T images
could not configure at all. ninja-build moves to the common apt list; it does
not change CMake's default generator, so it is inert for the other backends.

gcc-12 was nowhere in the tree, yet WITH_NORM defaults ON and
build_itn_deps.sh needs it, so the committed default was unbuildable in CI.
Install it, with the protobuf, absl, re2 and autotools that Sparrowhawk and
OpenFST need, gated on BACKEND so the other Go images do not carry it. The list
follows upstream's own docker/Dockerfile, trimmed of the gRPC, portaudio and
python entries a BUILD_GRPC=OFF build does not use. Text normalization stays ON:
downgrading it silently would ship a backend advertising a feature it lacks.

Also: make test depend on stage-libs, so LD_LIBRARY_PATH is not an empty
directory on a clean tree, and add an engine target so Dockerfile.golang's
cacheable prebuild layer is not skipped and a CUDA build stops recompiling all
of upstream on every Go-side change.

* fix(nemo-speech-cpp): pin protoc for ITN and make the norm stack its own target

Addresses the third review round.

Dockerfile.golang installs protoc 27.1 into /usr/local/bin, ahead of /usr/bin,
while libprotobuf-dev is the distro's 3.21 on noble and 3.12 on jammy.
Sparrowhawk resolves protoc from PATH at make time (configure.ac uses
AC_CHECK_PROG, so PROTOC substitutes to the bare word, and src/proto/Makefile.am
invokes it) and commits no pregenerated stubs, so the rule always runs. Code
generated by 27.1 includes google/protobuf/runtime_version.h and a
PROTOBUF_VERSION guard the older headers lack, so the WITH_NORM build could not
complete. Pin PROTOC to the apt one for that step; configure documents that a
pre-set value wins. The apt protoc and libprotobuf-dev come from one source
package at one version, which is the property that makes this correct.

The text-normalization stack is now a target keyed on a file build_itn_deps.sh
actually produces, rather than a side effect of the runtime library rule. As a
side effect make could not see whether it existed, so once the library was up to
date the script could never run again: a tree built WITH_NORM=OFF could not move
to ON, and make test hard-failed with no escape but a full 345 MB clean. It is
now built on demand and reachable on its own as 'make itn'. Staging keys on the
prefix existing rather than on WITH_NORM, so it stages what the tree actually
built, and package.sh's closure guard remains the backstop.

An already-configured build tree also now wins over the platform default, so a
tree built WITH_NORM=OFF is not silently reconfigured to ON by a bare make test,
which is what demanded gcc-12 from developers who chose not to have it. An
explicit WITH_NORM= on the command line still overrides both, and the ITN rule
preflights for gcc-12 with an error that names the alternative.

Move ninja-build out of the shared apt layer into the existing BACKEND-gated
block. Dockerfile.golang serves 225 matrix entries and only this backend
configures with -G Ninja, so the common list is byte-identical to master again
and no other image loses its cache.

Drop libabsl-dev and correct the comment that justified it. No base image here
ships protobuf 25, so nothing needs the absl split, and the cmake glob looks in
/usr/lib rather than the multiarch directory Ubuntu actually uses, so the
package could never have contributed anything.

* fix(nemo-speech-cpp): move the backend apt gate below the expensive layers

Addresses the fourth review round.

The nemo-speech-cpp apt block sat immediately after the shared apt layer, above
the Vulkan SDK build, the CUDA and ROCm installs, the Go toolchain and the
protoc download. Docker keys each layer on its parent, so inserting a step there
re-keys everything below it: a byte-identical shared layer is not enough, and
merging as it stood would have forced all of those to re-execute once for every
Go backend image. Move it down beside the existing opus, crispasr and
sherpa-onnx gates, which sit after those layers for the same reason.

Checked the ordering both ways before moving. Nothing between the two positions
uses these packages: the Vulkan and opus blocks install their own ninja and
pkg-config, go install protoc-gen-go needs the Go toolchain rather than protoc,
and the protoc 27.1 step is a release-binary download that needs neither
protobuf-compiler nor libprotobuf-dev. Nothing in the block needs anything those
layers provide; it uses only apt, and the mirror rewrite from the first RUN
persists in the image. It also runs no update-alternatives, so the default
compiler stays untouched for later layers. The diff against master is now a
single additive hunk with no shared layer touched.

Also preflight ITN_PROTOC. configure gates a preset PROTOC on test -n alone, so
a path that does not exist is accepted and the error surfaces much later as a
bare "No such file or directory" from inside make -C src/proto. The pin
introduced that failure on a box whose only protoc is in /usr/local/bin, which
worked before. Check it alongside the gcc-12 check and name the ITN_PROTOC=
override in the message.

* feat(nemo-speech-cpp): guard the empty option value and warn on a bad gpu index

An empty value like "vad_model:" must stay empty, since callers read the
empty string as "unset". That branch of resolve() had no spec: dropping the
guard left every spec green while parseOptions started returning the models
directory itself. Add the spec that fails without the guard.

A known key with an unparseable value is a typo, not a config from a newer
backend, and "gpu:banna" failed expensively: the model loaded, produced
correct output, and ran on CPU with no signal anywhere. Log it. Unknown keys
stay silently ignored, which is what keeps configs forward compatible.

* feat(nemo-speech-cpp): bind the C ABI with layout assertions

purego binds by name at runtime and the config structs are passed by pointer,
so both a renamed symbol and a mismatched struct layout would otherwise survive
a green build. registerSymbols names the failing symbol, and the layout specs
compare each Go mirror against the size the library reports for itself, against
the offsets a C compiler produces for the installed headers, and against the
default values upstream writes into the structs it returns.

Two of the bindings differ from the plan because the headers do. The plan's
nemo_speech_diar_segments signature omits the segmentation-config pointer that
diar.h declares as the second parameter, which would have shifted the output
buffer, the capacity and the count pointer one position each. And
nemo_speech_diar_stream_push_f32 was missing from the symbol table although
standalone diarization cannot work without it.

Also close the two panic and equality gaps left in family.go: ValueString panics
on a mistyped general.architecture, and the self-codec guard compared a Cleaned
candidate path against an uncleaned one, so a doubled separator let the primary
GGUF be selected as its own codec.

* test(nemo-speech-cpp): run the ABI specs in CI and refuse to skip them

The layout assertions were inert. TEST_PATHS does not cover this backend and
the per-backend list in test-extra had no entry for it, so nothing invoked the
package's tests. Add it next to depth-anything-cpp, supertonic and vllm-cpp,
the group whose own test target carries its build prerequisites; stage-libs
already pulls the native build chain, so no prepare-test-extra entry is needed.

The skip guard was also loader-inconsistent: librariesPresent stats bare
filenames relative to the working directory while openLibraries resolves them
through the loader search path, so any invocation other than make test skipped
every library-backed spec and still reported green. NEMO_SPEECH_REQUIRE_LIBS=1
turns that into a failure naming the directory and the remedy, and the Makefile
test target sets it. Unset, the plain skip survives so a developer without a
build can still run the pure-Go layer specs.

Trim the default-value fingerprint from roughly forty assertions to eight. It
was pinning tunables such as threads and flush_partial_chunk, so a legitimate
pin bump would have failed with a message reading like a layout error. What
survives is only header-documented contract: the lone non-zero max_alternatives,
the run of -1 sentinels and the zero that witnesses where it stops. Verified the
narrowed spec still catches a mirror and offset table corrupted in lockstep,
which is the one class only this layer sees.

* feat(nemo-speech-cpp): select the family at load and gate RPCs on it

Load sniffs the GGUF architecture, maps it to a family and dispatches to
the family's loader. requireFamily gates every other RPC, returning
Unimplemented naming both the loaded and the wanted family so a
misconfigured model YAML produces a message a user can act on.

The family is committed only once its loader has succeeded. A load that
fails part way through would otherwise leave the gate open on a handle
that was never created.

cstr uses runtime.Pinner rather than an ordinary Go allocation. The
address crosses the ABI as a uintptr, which the collector does not
trace, so incidental reachability through the release closure is not a
guarantee: a caller discarding that closure could have the bytes
collected before the create call reads them. Pinning is the sanctioned
mechanism, makes the release function do real work, and turns a dropped
release into a loud leaked-Pinner panic instead of silent corruption.

Free overrides the base no-op to destroy the handle and reset the
family. Every family owns C memory only its own destroy entry point can
release, so without this an unloaded model leaks an acoustic model.

* fix(nemo-speech-cpp): pin the load ordering, close the engineMu race

Three review items, plus a defect the race detector turned up.

The spec covering "no family selected after a failed load" wrote junk to
a .gguf, so Load returned at ggufArchitecture before a family was ever
chosen and the assertion was vacuous. Generalised the GGUF test helper
to take a string architecture, and added a spec that loads a magpietts
GGUF with no sibling codec, so familyFor succeeds and discoverTTSAssets
then fails. It self-guards on ggufArchitecture so it cannot degrade back
into the earlier path.

requireFamily read n.fam unlocked while Free wrote it under engineMu,
which the race detector confirms is a real race. pkg/grpc/server.go
calls Free without the backend lock every other RPC holds, so teardown
can land mid-request. withEngine now takes the lock, checks the family
and runs the body under one acquisition; two would leave a window for
Free to destroy the handle between check and use. The locking protocol
is stated in both directions for the RPCs still to be written.

Running -race also enables checkptr, which aborts on cstr's pointer
being read back by goString: converting a uintptr to a pointer is fatal
whenever the address lands in a Go allocation, so a pinned Go buffer can
never be dereferenced from Go. The pointer is for C alone. Both helpers
now document the one-way contract, and goString is tested against a real
C-owned string by rebinding the version symbol to return a raw char*.

* feat(nemo-speech-cpp): implement offline transcription

Create the ASR recognizer in loadASR and serve AudioTranscription.

Segment times are int64 nanoseconds, not seconds: the proto field is an
int64 that core/backend reads straight into a time.Duration, while the
runtime reports word offsets in milliseconds. Words are grouped into one
segment per consecutive speaker run, with the 1-based speaker tag carried
through and 0 (untagged) left unlabelled.

The whole RPC body runs inside withEngine so the family check and the C
calls happen under one acquisition of engineMu. Free runs without the
backend lock, so checking the family and then relocking would let a
teardown destroy the handle in the gap. The audio decode is inside the
closure too, which costs nothing: base.SingleThread already serialises
this backend's RPCs.

recognizeF32 guards zero-length PCM. &pcm[0] panics on an empty slice, so
Go never reaches the C side's own "empty audio" rejection, and a silent
clip or a truncated upload is ordinary input.

pkg/utils has no WAV decode helper, only the ffmpeg normalisation, so
audio.go pairs AudioToWav with go-audio the way parakeet-cpp does. It
returns the sample rate rather than a duration, since the C API resamples
off that number.

Also closes the write-side half of the race Task 5 fixed on the read
side: Load now holds engineMu across the family switch and the n.fam
commit, matching Free. The loaders still must not take it.

* feat(nemo-speech-cpp): implement streaming and live transcription

AudioTranscriptionStream drives a whole clip through the cache-aware
streaming API in 100 ms pushes, emitting each finalized utterance as a
delta and closing with the assembled result. AudioTranscriptionLive
serves the bidirectional RPC over the same session: config first, a ready
ack, deltas with word timings as utterances land, and a terminal result
when the caller closes its send side.

Both wrap their body in withEngine, so a stream holds engineMu for its
whole life and Free waits on it rather than destroying the recognizer
underneath a half-finished stream. That makes the way out load-bearing:
the file loop honours the request context between pushes, and the live
loop ends when the host closes the request channel, so a disconnected
client cannot pin the model against unload.

Only finals become deltas. The runtime applies punctuation and inverse
text normalization on finals only, so a final rewrites the utterance
rather than extending its interim, and delta on the wire is
newly-finalized text that consumers concatenate. Forwarding interims
would duplicate and mispunctuate every utterance.

The four streaming entry points sit behind an asrSession interface. No
NeMo GGUF is small enough to keep in the tree, so without that seam the
need-more-audio drain would have no test at all: nemo_speech_asr_stream_next
reports OK with a NULL handle when it wants more audio, which is a pause
rather than an end, and reading it either way round drops results or
spins forever.

Also folds in three items from the offline transcription review:

  - empty audio is now refused before anything crosses the ABI, not
    inside recognizeF32. The added integration spec caught the old
    ordering panicking on an unbound entry point instead of failing;
  - an undecodable sample rate is an error rather than 0, which this
    runtime reads as "already at the model rate" and would have made a
    wrong rate silently pitch-shift the audio;
  - AudioTranscription guards its result pointer instead of relying on
    an unstated invariant.

* fix(nemo-speech-cpp): make live deltas concatenate and fill segment words

runLive wrote the inter-utterance separator into the accumulated
transcript but emitted the delta without it, so a two-utterance turn sent
"one." and "two." while the terminal result read "one. two.". The live
consumer is the one that really concatenates: the realtime semantic-VAD
path joins the accumulated deltas with the empty string and clears them
only at a turn reset, never at an endpoint, so the running caption read
"one.two.". The separator now goes into the delta, as it already did on
the file path, and the terminal text is the verbatim concatenation rather
than a trimmed rebuild.

TranscriptSegment.Words was never populated, so a request asking for
timestamp_granularities ["word"] came back with no words at all even
though the timings were decoded. wordsToSegments now attaches them,
gated on the granularity the same way parakeet-cpp gates it, so a
transcript that did not ask for word timestamps does not pay for them.

Also: the final that comes back from the tail flush no longer claims an
end-of-utterance. It is the end of the stream, not a user yielding the
turn, and eou is what the realtime turn detector acts on.

The comment explaining why interims are suppressed led with the runtime's
postprocessing. The wire contract is the stronger reason and now comes
first: consumers concatenate deltas, so forwarding a growing hypothesis
assembles to "hehellhelloHello.". The postprocessing only explains why no
diffing trick would rescue them. It is also ITN and strip_formatting
rather than punctuation, which is off by default here.

* feat(nemo-speech-cpp): implement standalone diarization

loadDiarizer creates the Sortformer diarizer and Diarize serves the RPC
over a diarization stream: decode, chunked push, finish, then the
count-then-fill segments protocol.

nemo_speech_diar_segment carries start_time and end_time in SECONDS
already, not frame indices, so no conversion happens on the way to
DiarizeSegment.start/end and the model's seconds-per-frame is not
involved at all. The speaker label is the runtime's 1-based tag as a
decimal string, matching what wordsToSegments emits on the ASR path, so
the same speaker reads the same way whether a caller diarized a file or
transcribed it.

The six frame-geometry overrides are written as -1 rather than left
zero. c_api.cpp applies left_context_frames when it is >= 0 while every
other override needs > 0, so a zeroed config would silently pin the left
context to zero and change the model's streaming geometry.

nemo_speech_diar_segments writes *count before it rejects a buffer that
is too small, so a rejected fill still reports the size to retry with.
collectSegments uses that rather than truncating, bounded at four
attempts because the RPC holds engineMu for its whole body and an
unbounded retry would block an unload behind it.

Two DiarizeRequest knobs map onto the segmentation config, and the
proto and header names cross over: min_duration_on is the C
min_duration_sec and min_duration_off is the C min_gap_sec. Six fields
have no equivalent in this pipeline and are logged rather than dropped
in silence: num_speakers, min_speakers and max_speakers (Sortformer's
capacity is fixed by the checkpoint), clustering_threshold (there is no
clustering stage), include_text (no ASR here) and threads.

The empty-PCM guard fires before the stream is opened, so a silent clip
never reaches a purego entry point that would dereference &pcm[0].

* fix(nemo-speech-cpp): pin the diarizer geometry sentinels and cap the segment buffer

The six frame-geometry overrides were written as -1 with nothing
asserting it. c_api.cpp applies left_context_frames at >= 0 while the
other five need > 0, so a dropped sentinel there pins the model's left
context to zero, and the struct keeps exactly the same shape, which is
all the layout assertions can see. Extracting diarModelConfig makes the
values assertable: five specs now pin all six frame fields, the device
index, the declared size and the NULL preset, each frame field on its
own line so a missing sentinel names itself.

distinctSpeakers had a spec with three segments over three distinct
labels, which len(segs) satisfies just as well as the real thing. Four
segments over three labels makes it a spec that can fail.

collectSegments sized its buffer straight from a count the C side
reported, and make() panics rather than erroring on a length it cannot
satisfy, so an uninitialised size_t coming back across the ABI killed
the backend process instead of failing one request. A ceiling of 2^22
segments, upwards of 93 hours of audio at one 80 ms frame each, turns
that into a diagnosable error.

* feat(nemo-speech-cpp): implement TTS and streaming TTS

The PCM callback is compiled once per process behind a sync.Once, not once per
request and not once per load. purego.NewCallback writes into a fixed table of
2000 entries (purego/syscall_sysv.go) and never releases one, so a per-request
callback panics the backend process on the 2001st synthesis, and a per-load one
reaches the same ceiling on a server that swaps models. Synthesis is routed
through that single callback plus a user_data id: engineMu is per-model, one
process holds several models, so a single current-sink pointer would be
overwritten by two TTS models synthesizing at once.

Deviations from the brief, all verified against the real headers and proto:

  - TTS is TTS(*pb.TTSRequest) error and TTSStream is
    TTSStream(*pb.TTSRequest, chan []byte) error, per pkg/grpc/interface.go.
    The brief's context/pb.Result and server-stream forms do not implement the
    interface. The channel is closed on every path, including the family
    rejection, because pkg/grpc/server.go blocks on its drain goroutine and an
    unclosed channel hangs the RPC with the backend lock held.
  - The callback takes unsafe.Pointer, not uintptr. Converting a uintptr
    parameter back to a pointer is a checkptr violation that aborts under
    -race.
  - resolveSpeaker refuses to turn a negative number into a speaker index. -1
    is the C API's "use the default" sentinel, so the brief's rule would have
    made a request naming an invalid voice synthesize in the default voice
    instead of being rejected.

temperature and cfg_scale each write their override flag as well:
magpietts/runtime.cpp reads the float only when the flag is set, so a
temperature without it is silently discarded.

Also folds in Task 8's review finding on asr.go: the six bare -1 sentinels in
loadASR move to an asrDiarConfig builder reusing diarGeometryDefault, with
specs. src/asr/c_api.cpp applies left_context_frames at >= 0, so a dropped
sentinel pins the model geometry to 0 and no layout assertion can see it.

* feat(nemo-speech-cpp): surface NMT translation through Predict

nemo_speech_nmt_translate takes explicit source and target languages and has no
free-form generation or token-callback entry point, so there is no prompt in the
LLM sense. The pair comes from the source_language / target_language model
options, with an optional leading [src->tgt] directive as the only per-request
override, and PredictStream emits the whole translation as a single chunk
because the C API has nothing finer to give it.

Both RPCs wrap their body in withEngine so the family check and the C calls that
trust the handle share one acquisition of engineMu. PredictStream closes its
channel on every path, including the family rejection: this is the legacy
streaming contract, and pkg/grpc/server.go blocks on a drain goroutine that only
finishes when the channel closes, so leaving it open hangs the RPC rather than
failing it.

nmtTranslatorConfig is extracted so its four adjacent pointer fields can be
asserted against distinct sentinels. Transposing two of them changes neither the
struct size nor any field offset, so the layout assertions cannot see it.

Also removes goString, which had no production caller: every string-returning
symbol in abi.go is bound with a Go string return that purego converts itself.

* test(nemo-speech-cpp): pin the three-segment pair tag in an NMT directive

The directive regex allowed an unbounded run of two-letter segments per side, but
nothing tested it: narrowing that run back to a single optional segment left every
spec green. resolve_tag accepts a ready pair tag in one field with the other empty
(src/nmt/langpairs.cc), and those tags run to three segments (en-zh-cn, pt-br-en),
so a shorter pattern does not mis-split the tag, it fails to match the directive at
all and the whole bracket is handed to the model as text to translate.

The justification on the regex was also wrong and is corrected: pt-br and zh-cn are
two segments and parse either way. It is the single-field form that needs the run.

Renames the NMT handle to n.nmt so it stops sharing a name with the translator
interface, following n.synth, which is shortened for the same reason.

* feat(nemo-speech-cpp): register the backend and give its specs a CI job

Registers nemo-speech-cpp across every surface .agents/adding-backends.md
requires, and adds the CI job its unit suite never had.

backend/index.yaml gets the meta backend (capabilities map, no uri), a
development meta and 12 image entries. No amd and no intel capability keys:
upstream NeMo-Speech.cpp builds ggml with CUDA, Vulkan or Metal only, and
SystemState.Capability falls back to "default", so those hosts get the CPU
build rather than a tag that does not exist. The nvidia-cuda-* and
nvidia-l4t-cuda-* keys are present because getSystemCapabilities() refines an
NVIDIA host to them whenever the CUDA directory exists; without them every
modern CUDA host and Jetson would miss the map and quietly run on CPU.

.github/backend-matrix.yml gets 7 include rows and 1 includeDarwin row. No
hipblas and no sycl rows, for the same upstream reason. cpu and vulkan are
per-arch pairs sharing a tag-suffix so backend-merge-jobs builds a multi-arch
manifest: an ARM host with no NVIDIA GPU reports "default" and the Jetson image
does not cover it.

The CI job is the substantive part. make test-extra is dead on master, because
prepare-test-extra depends on a protogen-python target that does not exist and
no workflow invokes it anyway, so the entry added earlier in this series ran
nowhere. abi_test.go asserts the size and field offsets of every Go mirror
struct against the C ABI it is dlopened into, and those assertions are the only
defence against silent memory corruption after a purego symbol rename or an
upstream header change. tests-nemo-speech-cpp in test-extra.yml now executes
them on pull_request and on master, gated on the backend's own path filter.
The recipe sets NEMO_SPEECH_REQUIRE_LIBS=1, so a missing library fails rather
than skips. WITH_NORM=OFF skips the OpenFST leg and costs no coverage: nothing
in the four C ABI headers is conditional on it, so the layouts are identical.

Also registers the upstream pin with the bump bot, which the backend Makefile
already claimed but was never wired up, and adds the BackendCapabilities entry
so a hand-written model config gets a real usecase surface. PossibleUsecases is
the union of the four families and DefaultUsecases is transcript alone, the
audio-cpp pattern. No VoiceCloning key: MagpieTTS synthesizes from baked
speaker ids, not a reference clip.

No gallery entries: publishing converted GGUFs is a follow-up.

ModelIdentity needs no work in this backend. main.go serves through
grpc.StartServer, so every RPC lands on pkg/grpc's shared server wrapper first,
and checkModelIdentity is the first statement of all seven handlers this
backend implements. A second check inside NemoSpeech would be unreachable and
would risk diverging from the cross-language sentinel the router matches on.
AudioTranscriptionLive stays unguarded because TranscriptLiveRequest carries no
ModelIdentity field at all, which is a proto-level gap affecting every backend
and needs its own change.

* fix(nemo-speech-cpp): build the CUDA-13 Jetson image the l4t-cuda-13 key needs

The nvidia-l4t-cuda-13 capability pointed at nvidia-l4t-arm64-nemo-speech-cpp,
which is built on nvcr.io/nvidia/l4t-jetpack:r36.4.0 and therefore links ggml
against CUDA 12. A Jetson whose CUDA 13 runtime is present reports that
capability and would have pulled an image with no libcudart.so.12 to dlopen,
failing hard at load. That is worse than omitting the key: with no key
Capability() falls back to "default" and the host gets a working CPU build.

Fixed the way parakeet-cpp and moss-transcribe-cpp already do it, by shipping
the second L4T image rather than dropping the key. Nothing prevents building it
here: those peers use plain ubuntu:24.04 on ubuntu-24.04-arm with the same
Dockerfile.golang as this backend's other rows, and every package in the
nemo-speech-cpp apt gate exists on noble arm64.

Adds the -nvidia-l4t-cuda-13-arm64-nemo-speech-cpp matrix row and its two index
entries, repoints the key on both metas, and rewrites the capability-map comment,
which had the reasoning backwards.

Also adds the documentary inferBackendPath branch, matching all six sibling
*-cpp Go backends. Behaviour is unchanged; the generic golang fallthrough
already resolved this backend correctly.

The previous commit message said "all seven handlers" of the shared gRPC
wrapper. There are eight RPC entry points: seven are guarded by
checkModelIdentity and AudioTranscriptionLive is the unguarded eighth, which
that message already called out separately. Wording only.

* docs(nemo-speech-cpp): document the backend and list it in the importer

Adds docs/content/features/nemo-speech-cpp.md, alongside the audio.cpp page
that is its closest sibling, and cross-links it from the speech-to-text,
diarization, text-to-speech, backend-type and compatibility-table pages so the
backend is reachable from every surface that lists its modalities.

The page covers the architecture-to-family table, every option key with a model
YAML per family, the translation prefix directive, the acceleration matrix, and
the four limitations this backend ships with: Linux-only inverse text
normalization, suppressed interim streaming results, the library's default
translation context and generation limits, and the absence of gallery entries.

knownPrefOnlyBackends gains the backend so it appears in the /import-model
dropdown. It stays preference-only and AutoDetect=false: general.architecture
lives inside the GGUF where no remote-repo probe can read it, and a translation
model carries an ordinary LLM architecture with no NeMo-specific marker.

* docs(nemo-speech-cpp): correct the translation limits, the macOS gap and the TTS conversion

Three factual errors found in review, all of them the kind a user would act on.

The translation limits were described backwards. Input longer than the 1024-token
context is rejected, not truncated: translator.cpp throws "nmt: prompt too long
(N tokens) for context 1024", which reaches the caller as a failed request. What
is silently cut is the output, by the max_new_tokens loop at 256. The bullet now
separates the two and says which one fails quietly.

The macOS gap covers TTS text normalization as well. Both directions sit behind
the single NEMO_SPEECH_WITH_NORM flag, which the Makefile forces off on Darwin,
so tn_dir is as inert there as itn_dir. Neither fails the load: both warn and
carry on. pnc_model really is unaffected, since punctuation is compiled in
unconditionally. The tn_dir row in the option reference gained the caveat the
itn_dir row already had.

The TTS conversion procedure produced a model that could not load. It converted
MagpieTTS and stopped, leaving no NanoCodec, which the same page lists as
required; following it gave "no NanoCodec GGUF found next to ...". Both halves
are now there, each with the download that feeds it, so the block runs top to
bottom on a clean machine.

Also: any negative gpu value pins TTS to the CPU, not only -1, and FLAG_CHAT
additionally surfaces the model in the web UI chat picker.

* fix(nemo-speech-cpp): map every C status, not just the NMT one

INVALID_ARGUMENT was translated to codes.InvalidArgument at exactly one of
sixteen C call sites. Everywhere else a non-zero status collapsed to
codes.Internal, so the same backend answered an unsupported language pair with
HTTP 400 and an unknown TTS voice, which is the same class of caller mistake
against the same process, with HTTP 500. Status 4 is CANCELLED on the ASR and
TTS surfaces and was reported as a backend failure rather than as the consumer
having stopped listening.

asr.h, tts.h and nmt.h each declare their own status enum and diar.h reuses the
ASR one; the values they share agree, and the single divergence is that NMT
declares no CANCELLED because nemo_speech_nmt_translate has no callback for a
consumer to stop with. That is an absence, not a disagreement, so one table
serves all three. status.go carries it, with the header line numbers and a note
that a pin bump has to recheck it: purego binds by name and the status crosses
as a bare int32, so nothing in the build or the linker can see a drift.

New specs cover the whole enum, unknown values, and one real INVALID_ARGUMENT
per family driven through the shared objects rather than through the Go mapping
asserting against itself.

Also add UsecaseChat to this backend's capability entry, which the docs already
told operators to set for translation models. chat is a gallery filter key and
completion is not, so GET /api/backends/usecases would have greyed the Chat
filter out and hidden a Riva-Translate gallery entry from the one filter that
fits it. The flag gates no endpoint; it makes the model eligible as the default
chat model and puts it in the web UI chat picker, both of which Predict and
PredictStream already serve.

* fix(nemo-speech-cpp): audit the gosec unsafe and file-inclusion sites

gosec flags 13 alerts on this backend: one G304 and twelve G103. Each was
checked individually rather than blanket-suppressed, and each annotation
states what makes that particular site safe.

The G304 at audio.go is a false positive. The opened path is
filepath.Join of a directory the function just created with os.MkdirTemp
and a constant basename; the request-controlled path is the input to
AudioToWav and never reaches the open.

The twelve G103 sites are the package's three established shapes, and
every one was verified against them: cstr and pinPtr take the address of
something pinned on the line above and return it one-way (nothing in the
package converts either result back, which is what keeps checkptr out of
it under -race), and each *Create hands C a stack-local POD config whose
uintptr members are cstr allocations or pinPtr addresses held by a pinner
the loader unpins only after the call. The two slice-building sites are
bounded by construction: DiarSegments is handed exactly len(buf) with the
buffer sized under maxDiarSegments and a reported count larger than it
rejected rather than sliced to, and the TTS callback copies out a slice
whose length is the length the runtime declared for that buffer.

Separately, sampleRateOf gets a real fix rather than an annotation.
go-audio reads the WAV header's sample rate from an unsigned 32-bit field
into an int, so a header claiming more than 2^31-1 passed the "> 0" test
and then narrowed to a NEGATIVE rate, which the runtime would take as a
resampling ratio. AudioToWav cannot produce one today, but that is a
property of another package and this function exists precisely because
the rate is read back rather than assumed, so the bound is enforced here
and pinned by a spec.

The four remaining integer narrowings are annotated with the bound that
makes each safe: the WAV payload length is already checked against
maxWAVDataBytes, the speaker count is bounded by maxDiarSegments, and the
two segment ids are the proto's own int32 wire type.

* fix(nemo-speech-cpp): skip the CUDA-only ggml patch series on darwin

The macOS backend build died in patch-ggml:

    scripts/apply-ggml-patches.sh: line 56: mapfile: command not found
    make[1]: *** [patch-ggml] Error 127

mapfile is a bash 4 builtin (and its -d flag needs 4.4). macOS ships bash
3.2.57 as /bin/bash and GitHub's runner images add no newer one, so the
bare `bash` the recipe resolves from PATH cannot run upstream's script.

Rather than hunt for a capable bash that the runner does not have, drop
the step where it does nothing. ggml-patches/ is a CUDA series: every
kernel it adds is under src/ggml-cuda/, and its whole footprint outside
that directory is an op enum plus prototype in include/ggml.h, the
constructor and a name-table entry in src/ggml.c, and two ggml-cpu lines
that make the CUDA-only op report unsupported and abort. Nothing it
touches is compiled into a Metal kernel or changes a CPU one.

The project's own references to patch-only ggml symbols sit behind
NEMO_SPEECH_FUSED_RELPOS_ATTN and NEMO_SPEECH_FASTCONFORMER_CUDA_FUSIONS,
which cmake already forces OFF without GGML_CUDA, or behind
NEMO_SPEECH_GGML_PATCHED itself, which guards a GGML_TENSOR_FLAG_Q8_PLANAR
write that a non-CUDA buffer throws before reaching. So passing
NEMO_SPEECH_GGML_PATCHED=OFF costs the Metal build nothing, and it is
required once the series is skipped: that flag is what stops the ASR
sources referencing a tensor flag stock ggml does not define.

This is upstream's own Metal configuration. Its metal-* and vulkan-*
CMake presets inherit the cpu-* ones, which set NEMO_SPEECH_GGML_PATCHED
to OFF; docker/Dockerfile and scripts/windows/build.ps1 do the same for
their non-CUDA targets. LocalAI's Makefile never passed the flag at all
and so inherited the CUDA default everywhere.

Linux is untouched and keeps applying the series, including its
idempotency and its hard failure on a patch that does not apply. The gate
is the same uname test the WITH_NORM block above already uses, and both
branches keep the order-only clone prerequisite, which on a WITH_NORM=OFF
tree is the only thing that pulls sources/ in.

* fix(nemo-speech-cpp): restore std::binary_function for MeCab on libc++

NEMO_SPEECH_TTS_WITH_JA=ON compiles Open JTalk's bundled MeCab, and
mecab/src/dictionary.cpp derives a comparator from std::binary_function,
which C++17 removed. libstdc++ still ships it as deprecated-but-present
under -std=gnu++17, so Linux never notices. libc++ compiles it out and
the macOS arm64 build dies with "no template named 'binary_function' in
namespace 'std'".

This is ours, not an upstream regression: upstream defaults both
NEMO_SPEECH_TTS_WITH_JA and NEMO_SPEECH_TTS_WITH_ZH to OFF and the OSS
drop carries no CI at all, so that target is never built there. Upstream
does already carry the equivalent workaround for MSVC's STL
(_HAS_AUTO_PTR_ETC plus /FIfunctional) but has no libc++ branch.

libc++ gates the two templates on
_LIBCPP_ENABLE_CXX17_REMOVED_UNARY_BINARY_FUNCTION, and has since LLVM
16, older than any clang Xcode still ships. The name is the whole
problem: _LIBCPP_ENABLE_CXX17_REMOVED_BINDERS covers bind1st, bind2nd,
ptr_fun and mem_fun and not unary_function or binary_function, and the
umbrella _LIBCPP_ENABLE_CXX17_REMOVED_FEATURES no longer exists in
libcxx at all. A wrong name preprocesses fine and fixes nothing.

Applied through CMAKE_CXX_FLAGS rather than to the one target, because
the tokenizer CMakeLists is upstream's and sources/ is a pinned
checkout. Project-wide is also the safer scope: the macro decides
whether libc++'s internal __binary_function alias resolves to
std::binary_function or to __binary_function_keep_layout_base, a base
class of std::less and friends, so defining it for a subset of
translation units would give those class templates two spellings in one
binary. Both bases are empty and, at C++17, carry identical members, so
the define changes no layout and no ABI.

Darwin only. On Linux the branch is unreachable and the macro is not a
name libstdc++ knows, so it would be inert even if taken; a Linux
configure with the flag forced on puts it on all 23 C++ TUs of
nemo_speech_openjtalk_frontend including dictionary.cpp at -std=gnu++17,
and on none of the 16 C TUs.

Mandarin needs nothing: cppjieba v5.6.7 and limonp have no removed C++17
constructs left (limonp replaced std::not1 and std::bind2nd with
lambdas) and cppjieba's own CI builds macos-14 and macos-latest at C++11
through C++20.

* fix(nemo-speech-cpp): repair OpenFST's FstImpl::operator= for gcc-14

The first WITH_NORM=ON build failed compiling fst_normalizer.cpp against the
installed OpenFST 1.8.3 headers:

  fst.h:690:59: error: no match for 'operator=' (operand types are
    'std::unique_ptr<fst::SymbolTable, ...>' and 'fst::SymbolTable*')

FstImpl's copy-assignment operator assigns the raw pointer returned by
SymbolTable::Copy() straight to a std::unique_ptr member. No C++ standard
allows that, so the line is ill-formed everywhere; it survived because nothing
instantiates FstImpl::operator= and gcc up to 13 only checks a template
member's body when it is instantiated. gcc 14 resolves non-dependent operator
expressions at template definition time, so it rejects the line in any
translation unit that includes <fst/fst.h>. The CI diagnostic confirms the
phase: it reads "In member function", not "In instantiation of", and carries
no instantiation backtrace.

That is why this surfaces only here. build_itn_deps.sh compiles OpenFST with
gcc-12 and upstream's own images build the runtime with gcc-13, so neither
compiler reaches the check; backend/Dockerfile.golang installs gcc-14 and
promotes it with update-alternatives, and fst_normalizer.cpp is the one
translation unit in this backend that includes OpenFST.

Fix it in the installed ITN prefix, which is the only copy the cmake build
compiles against, using the same .reset() spelling FstImpl::SetInputSymbols
already uses for the identical operation. libfst.so is linked before this runs
and cannot contain the function, since no compiler could ever have emitted it,
so there is no ABI or ODR consequence. The rule is guarded on both sides so a
pin bump to a fixed OpenFST fails loudly rather than silently no-opping.

Verified with a real gcc 14.2: the CI error reproduces byte for byte from a
file whose entire content is '#include <fst/fst.h>', and gcc 14 reports
exactly two errors over the whole OpenFST include closure this backend uses,
both of them these two lines. After the patch that closure compiles clean
under gcc-14 with the target's own flags. The step is reachable only under
WITH_NORM=ON, so 'make -n stage-libs WITH_NORM=OFF' mentions neither it nor
the ITN build, and darwin, which defaults WITH_NORM to OFF, never evaluates it.

* fix(nemo-speech-cpp): install cmake 3.31 on bases that ship less than 3.26

The JetPack r36.4.0 row dies on the first line of NeMo-Speech.cpp's
CMakeLists.txt:

  CMake Error at CMakeLists.txt:3 (cmake_minimum_required):
  -- Configuring incomplete, errors occurred!

Upstream opens with cmake_minimum_required(VERSION 3.26). That base image is
Ubuntu 22.04 jammy, whose apt cmake is 3.22.1, so configure aborts before it
reads a single one of the backend's -D flags. Every other Linux row in this
block is noble, which ships 3.28 and clears the bar, so the failure is one
base image wide rather than a code problem. Everything before it on that row
had already worked, including the OpenFST and Sparrowhawk ITN build.

No other Go backend needs this. parakeet-cpp and moss-transcribe-cpp share
the same JetPack base and both declare cmake_minimum_required(VERSION 3.18),
and nothing in the repo installs a cmake newer than the distro's, so there is
no existing pattern to reuse. Nothing depends on jammy's cmake staying 3.22
either: build_itn_deps.sh never invokes cmake at all, since OpenFST and
Sparrowhawk are autotools builds.

Kitware's release tarball rather than their APT repo or pip. The tarball is a
pinned URL with a published checksum, so an upstream release cannot change
what lands here. The APT repo does carry jammy arm64, but it serves a moving
latest that today is CMake 4.4, and 4.x drops compatibility with
cmake_minimum_required below 3.5, which vendored third_party subprojects
still declare; pinning it there would mean tracking Kitware's Debian revision
string instead of an upstream version. pip would drag a Python toolchain into
a backend that has none. 3.31.12 is the last 3.x release, so it clears 3.26
while keeping the CMake 3 policy surface, and it stays close to the 3.28 the
green noble rows already use. The binaries need only glibc 2.17 and carry no
libstdc++ DT_NEEDED, well under jammy's 2.35. doc/, man/, ccmake and cmake-gui
are not extracted; the final image is FROM scratch, but there is no reason to
page 100 MB of Qt GUI and docs through the CI cache.

Gated on the installed cmake actually being older than 3.26, so the rows that
already build green keep configuring with exactly the cmake they use today,
and folded into the existing ${BACKEND} block rather than added as a new
instruction, so no other Go backend image gains a layer and nothing above the
Vulkan SDK, CUDA, Go and protoc layers moves.

The symlink lands in /usr/local/bin and shadows apt's cmake. Unlike the protoc
shadowing that broke Sparrowhawk earlier in this series that is inert: protoc
has to agree with the libprotobuf headers it generates against, whereas cmake
links nothing into the product and has no ABI relationship with anything in
the image, and it resolves the symlink back to /opt to find its own Modules/
tree, so a 3.31 binary can never read 3.22's modules.

The version test avoids $(...) deliberately. BuildKit delivers a RUN heredoc
through an outer shell with an unquoted delimiter, so a command substitution
runs there, too early, in a container where the files it reads do not exist
yet, and its empty output is pasted into the script; the first draft took the
install branch on every row because of it.

Verified by building the block against nvcr.io/nvidia/l4t-jetpack:r36.4.0
arm64 under qemu, the row's actual base image: cmake 3.22.1 detected, tarball
checksum verified, 3.31.12 installed, and a cmake_minimum_required(VERSION
3.26) project configures with -G Ninja and builds, with CMAKE_ROOT resolving
to /opt/cmake/share/cmake-3.31. Same on ubuntu:22.04 amd64 and arm64.
ubuntu:24.04 skips the install, gains no /opt/cmake and still configures on
/usr/share/cmake-3.28. The NeMo-Speech.cpp compile itself on JetPack CUDA 12
is not reproducible here and remains for CI.

the time #11318 merged; #11318 appended its own copy after

this double only exists so the holder can be constructed.

mudler's LocalAI [bot]andEttore Di Giacinto 5cb0c1a872 feat(ui): close the gap between the shipped UI and the design mocks (#11307)
* feat(ui): give the Operate overview real numbers and traces a latency shape

First two items from a component-by-component comparison against the mocks.
The pattern that audit found: everything newly built matched, everything
pre-existing got the palette but not the layout, and an "absent rather than
empty" rule hid most of the overview exactly when someone was looking at an
idle installation.

**The headline grid is always rendered**, including at zero, with a fourth cell
for host memory. Hiding it removed the page's structure precisely when it was
most likely to be read, and "0 failed" is information — an absent panel is not.
The quiet case is now said in a line underneath instead of by showing nothing.

**The sections state counts** rather than listing their destinations: backends,
models, updates and running operations instead of the words "Usage and traces".
That needed installed backend and model counts in the summary context, which
are two more cheap reads on the poll that was already running.

**Traces rows carry latency as a bar as well as a figure**, scaled against the
slowest request currently in view and turning amber past two seconds. The table
had no latency column at all — the number was buried in the expanded detail, so
the shape of the tail was invisible while scanning. Scaling against the view
rather than an absolute ceiling is deliberate: what matters when reading a page
of traces is which of these are the outliers, and an absolute scale flattens
every row on a fast installation into nothing.

* feat(ui): name the engine on Home's resident models, and add jump-back-in

Third item from the mock comparison.

The mock showed each resident model with the engine serving it. /system carried
only the id, so the audit recorded this as blocked on a server field — but the
config loader is already in scope where that response is built, so it is one
lookup. SysInfoModel gains an optional `backend`, resolved from the model's
config and omitted rather than guessed when there is none (a loose file, or a
config since removed). Home renders the column blank in that case; the test
pins both halves of that.

Memory per model stays out. It is not one lookup — it would mean asking each
backend process — and inventing a number beside a real one is worse than
leaving the column off.

"Jump back in" is the block the mock had and Home did not. The quick-links row
above it is a set of first-run actions; these are the three places someone
returns to, each stated with what it currently holds rather than as a bare
label.

* feat(ui): rank the recommended models as lanes instead of equal cards

The hardware recommendations were a grid of equally-weighted cards. The list is
already sorted by fit, and a grid throws that order away: three cards side by
side say "pick one", when the page has actually formed an opinion about which
one.

They are lanes now, read top to bottom in fit order, with the leader carrying
the single amber "Best fit" label and the rest marked "Also fits". One opinion
per page — the alternatives are alternatives, not runners-up each worth their
own colour, which is how a strip of coloured badges ends up meaning nothing.

Below 720px the size and VRAM columns drop and the lane keeps the name and the
install action, which are the two things a narrow screen needs.

The existing panel spec moves off .rec-models-item onto .lane rather than being
deleted; dismissal, collapse, keyboard operation and install all still pass
unchanged, and there is a new assertion that exactly one row is called out.

* fix(ui): drop capsule chips app-wide, and un-break the empty voice library

**Pills are gone.** A capsule radius reads as a tag floating on the surface,
which fights a system whose structure is hairlines and square corners — and
with chips on Discover, Host, Activity and the biometrics pages, "some pages
have pills" was the real inconsistency rather than any one page.

Sixteen selectors move to the small radius: filter buttons, tab pills, activity
and biometrics chips, file and count badges, the jump-to-latest control, the
nav badge. Round *buttons* keep their circle — .lightbox__nav and
.home-send-btn are circles, not capsules — as do every progress track, status
dot and avatar, which are round because they are round, not because they are
tags.

**The empty voice library was unusable.** `.voice-library-empty` sets
min-height: 430px, border: 0 and background: transparent — a description of the
empty PANEL — and it had been attached to the action instead. The create button
was therefore a 430px transparent box that pushed itself out of the panel and
could not be seen. Moved onto the container it describes, which now centres its
action rather than letting it fall off the bottom. Same class-mangling shape as
the Agents header fixed earlier.

* feat(ui): put Host's headline figures on the shared hairline strip

Host had shadowed, clickable StatCards above a page that already has a rail, a
pane and a tab bar — a second dashboard language on one screen, and a different
one again from the figures inside its own detail pane.

The Operate overview's figure grid is generalised into a shared `.stat-strip`
and Host adopts it, so the two pages read as one system: same cell, same figure
scale, same tone vocabulary, and the same hairline grid the split-view StatGrid
already uses. The cells stay clickable and still route into the tab and filter
they describe, because a count is worth more when it is also the way to the
thing counted.

Tone is spent only where the number means something — running and updates when
non-zero — since a strip where every cell is coloured has no emphasis left.

Two bugs made on the way, both now covered:

- The first version put `<button>` elements inside a `<dl>` with `<dt>`/`<dd>`
  inside the buttons. Neither is valid, the browser re-parents both, and the
  cells collapsed. These cells are a set of controls, so a plain container of
  buttons is also the honest markup.
- Even correct, the strip rendered 2px tall: `.page--app` is a flex column
  whose split view takes flex:1, so a child with no intrinsic minimum is shrunk
  away. The old cards survived only because `.stat-card` carried
  min-height:96px. The strip now declines to shrink, with a test pinning it.

The stat-card specs are retargeted rather than deleted: they were written to
guard a class collision on a page that no longer uses cards, so they now guard
the strip's labels and its height.

* feat(ui): make Backends notices an edge rather than a filled card

The install and upgrade banners were tinted cards with a full border. A filled
panel makes every notice shout at the weight of an error, which is how notices
stop being read — and Backends shows one on most visits, so it was shouting
routinely.

They are now a hairline with a coloured left edge, the same treatment the
Operate overview gives rows that want a decision, so "this needs you" looks the
same wherever it appears. Counts in the notice take the monospace tabular
figures the rest of the console uses.

Also drops the last inline style on the page, and refreshes the inline-style
baseline, which has read 624 against a real count since #11288 landed. The gate
exits 0 either way, so nothing was failing — but a baseline 86 above the truth
would have let that many inline styles back in unnoticed. Now at 538, which
tightens the ratchet rather than loosening it.

The spec creates the upgrade it asserts on rather than skipping when the mock
has no notice: a test that skips is a test that proves nothing.

* feat(ui): finish the mock parity list, and stop hiding the recommendations

The last two items from the audit, plus a correction.

**Discover's use-case shelf is lanes.** These are a list of ways in, read in
order; a grid of equal cards asks the reader to compare them, which is not the
choice on offer.

**The request panel reaches every generator.** Video, 3D, Sound and Audio FX
join Images and Speech, so each one teaches its own endpoint rather than two of
six doing it. Audio FX records the fields that shape the request rather than
the bytes, since its payload is multipart.

**Recommendations no longer collapse themselves.** They were folded away by
default once anything was installed. That is the page's one opinion about this
host, and an opinion hidden by default is one the reader never gets. Someone
who disagrees can still collapse it and that choice is remembered — the
difference is that we no longer make it for them. Three specs asserted the old
default and now assert the new one.

The use-case heading also sat a line's width from the text it introduces, so
the two read as one paragraph. It has air under it now, and the shelf is
separated from the recommendations above it.

Two tests removed rather than kept: a generator loop whose only real assertion
was `expect(endpoint.length).toBeGreaterThan(0)`, and an earlier card-gap guard
that could only skip. A test that cannot fail is worse than no test, because it
reads as coverage.

* fix(ui): make the Host figures legible and give the strip its spacing back

Three defects introduced by the Host redesign, all found by looking at the
running app rather than by the suite.

**The figures were invisible.** "Running now" and "Updates available" rendered
pure black on the dark ground. Two causes compounding: the `--muted` tone alias
never landed, because the source rule has extra spaces before its brace and the
exact-match edit missed it silently; and a `<button>` does not inherit colour,
so with no tone rule the value fell back to the user agent's `buttontext`.
Both fixed, and a test now fails on any figure computing to pure black.

**The strip sat flush against the resources panel.** `.stat-strip` declares
`margin: 0 0 ...` and is declared later in the file than `.manage-summary`, so
the shorthand quietly won and the top margin became zero. Raised to
`.stat-strip.manage-summary` so it beats the shorthand on specificity rather
than on declaration order, which is the kind of thing that breaks again the
next time a rule moves.

**Discover's use-case heading had a doubled gap.** `.zero-pane` is a flex
column that already separates its children; adding a margin on top of the gap
stacked the two. The margin is gone and the heading keeps only its own breathing
room.

* feat(ui): make Studio's tabs path segments rather than a query parameter

`/app/studio?tab=images` reads like a filter applied to a page. It is
navigation: a different generator, with its own state and its own deep link. It
is now `/app/studio/images`, with the overview at `/app/studio`.

Legacy `?tab=` links are redirected once to the path form, replacing the
history entry so Back does not bounce between two spellings of the same place.
Bookmarks and older links keep working and land on the canonical URL rather
than a second version of it, which is the part worth having a test for.

The nine `?tab=` references were all in specs, none in docs, so the migration
is contained. They move to paths, and a new spec pins the redirect.

* feat(ui): make the hardware recommendation a section, not a dismissable card

It was a bordered card with a collapse control and a close button, sitting
inside a pane that is otherwise hairline sections. Two problems: it read as
something bolted onto the page rather than part of it, and treating it as an
interruption to be shut is the wrong frame for the one thing the page has to
say about the machine it is running on.

It is now a plain section with the same heading treatment as the shelves below
it. The collapse state, the dismissal, their storage keys and the legacy key
read for backwards compatibility all go with it, along with the installedCount
prop that existed only to pick a default collapse.

Five specs described behaviour that no longer exists and are removed rather
than adjusted — collapsing, dismissing, persistence of both, and the toggle's
keyboard handling. One new spec asserts the replacement contract: no control
with aria-expanded, no dismiss, and no card border.

* fix(ui): restore every stripped icon and every default-chrome control

You reported two broken icons. They were not two: an earlier automated edit had
stripped the `fa-*` class from twenty `<i>` elements across eleven pages, and an
`<i>` with no icon class renders nothing at all. Settings' save button, the
voice-profile back link, and eighteen others — agent row actions, task and job
buttons, import and create actions — were all drawing empty space.

Each is restored from its own context rather than a blanket icon: the agent row
gets pause/play, pen, comments, file-export and trash; the fine-tune toggle
swaps plus for xmark as it opens; the P2P documentation link gets the
external-link glyph.

The same edit left controls without their classes. Fine-tune's "Import config"
was rendering in the browser's own chrome, and `.p2p-cmd__copy` set a border
but no background, so it fell back to `buttonface` — a pale grey chip on a dark
command block. FineTune's "New job" also had its icon classes folded into the
button's className, the same mangling already fixed on the Agents header.

Rather than fix the reported two and wait for the next report, this adds a
standing audit: twenty-five routes are walked and the test fails on any visible
control rendering with user-agent chrome, or any `<i>` without an `fa-*` class.
It found the three remaining cases after the first sweep, and it is the reason
the next one cannot ship quietly.

mudler's LocalAI [bot]andEttore Di Giacinto 58ea2f5d79 feat(ui): give Operate and Studio a front door, and fix two layout regressions (#11305)
* feat(ui): give Operate a front door and fold six rail groups into four

Opening Operate ran firstVisiblePath() and landed on Backends, because
Backends happens to be written first in operateConsole.groups. The section
that should answer "is anything wrong" opened on a package manager, and
nothing was reported until you visited it.

Adds /app/operate. Its one irreplaceable block is "Needs attention", which
is empty when nothing is wrong and says so in a line rather than rendering a
reassuring green panel. It collects stale backends, failed operations and
unhealthy nodes. Everything else on the page is a summary you could already
assemble by visiting four others.

The rail regroups from six headings to four: Inference and Activity were both
"the runtime right now", Access and System were both administration. No
destination is removed and no gate changes, so isConsoleItemVisible and
consolePaths are untouched. Overview leads the first group, which is what
makes firstVisiblePath() return it without knowing it exists.

Rail entries now carry a signal beside the label. This does not replace the
sidebar badge and is not built as if it does: the badge stays on the
always-visible sidebar entry for the reason recorded in Sidebar.jsx, that the
rail exists only on Operate routes and can be collapsed. The signals are
orientation while inside Operate, so they are aria-hidden and nothing urgent
depends on them alone.

OperateSummaryContext polls once for the whole console, following
OperationsContext, which exists because per-consumer setInterval against one
endpoint was the defect it fixed. It is mounted by ConsoleLayout for the
Operate console only, so "poll only while in Operate" needs no route check.
Built on usePolling, so it pauses on a hidden tab. Operations are read from
OperationsContext rather than polled a second time, and each source degrades
to no-signal on its own so one dead endpoint cannot blank the rest. It reads
the cached GET /api/backends/upgrades and never the POST that forces a real
registry check.

Traces and Usage get no signal yet: /api/traces returns the list, so a count
would mean fetching every trace to render one number. A counts endpoint is
the honest fix and is scoped separately.

Full e2e suite green (369 passed, 4 skipped), including a render-smoke entry
for the new route.

* feat(ui): open Studio on what this machine can actually make

Studio was a tab strip over six generators that opened on Images, which was
never a decision, only the first entry in BASE_TABS. Nothing said which
modalities this installation could run, so the way to learn that video had no
model was to pick the tab and find an empty select.

Adds an overview tab and makes it the fallback. Explicit tabs still win, so
existing deep links keep working; anything unrecognised or gated now lands on
the overview rather than Images.

Each tab carries a dot: filled when an installed model advertises that
modality, hollow when nothing serves it. That is the feature in one detail,
turning the strip from navigation into a report of what the machine can do
before anything is clicked. The dot is aria-hidden because the overview states
the same facts in words and the dots change as models load.

Two kinds of unavailable, which had to stop looking alike:
  - switched off, via a permission: no tab and no lane, unchanged
  - available with no model: a lane, and a route to installing one

Studio now owns one MODALITIES table so the tab strip and the overview cannot
disagree about what exists, and calls useModels() once, unfiltered, grouping in
the browser. useModels(capability) fetches the whole list and filters locally,
so a hook per modality would have been six identical requests to
/api/models/capabilities on every mount. There is a test for that.

Recent outputs read every localStorage store through a new
readAllMediaHistory(), which avoids mounting five hooks that carry save timers
the overview has no use for. 3D is read separately through use3DHistory rather
than folded in: its entries are GLB blobs in IndexedDB, so they cannot come
from the same synchronous read.

Typical cost is the median of this machine's own history, not a guess, and
renders as a dash when there is nothing to go on.

* fix(ui): stop the stat cards and the console rail breaking on small screens

Two unrelated causes behind one report that /app/manage looks wrong when the
window is narrow.

The stat cards were being laid out by the wrong rule at every width. Two
different components both claimed `.stat-grid`: the dashboard card strip that
holds .stat-card children, and the detail-pane StatGrid the split views
introduced further down App.css. Being later, the second won every shared
property, so the cards got its 120px columns and its 1px hairline gap in place
of their own 180px columns and spacing-md. Four cards were packed onto a row
that fits two, labels wrapped to three lines and clipped, and the icon crowded
the value. Renamed the strip to `.stat-cards`, after the children it actually
holds, which also removes the mismatch of a `.stat-grid` container full of
`.stat-card`s. The split-view component keeps `.stat-grid` and its BEM parts.

The expanded console rail had no bounded height. Thirteen destinations stacked
in one column is taller than a phone, so opening the menu pushed the page's own
heading past the fold: the menu replaced the page rather than annotating it.
Capped at 55vh with internal scrolling below 768px, so the content behind stays
reachable.

Both are asserted on behaviour rather than markup: no stat-card label may be
clipped, the card gap must not be the detail pane's hairline, and expanding the
rail must leave the page heading on screen.

* feat(ui): retemper the palette to localai.io and add the lane primitive

The token half of the style transfer, plus the shared list idiom the two
overviews had each grown their own copy of.

theme.css moves from Nord to the website's palette, variable names preserved so
every consumer moves with it: ground #13171f -> #0d1117, accent frost cyan
#88c0d0 -> action blue #4f8cff, success sage -> mint #56d6a4, warning -> the
amber #f1b95d the site spends only on the thing asking for a decision. Eyebrows
go mint. Dividers become an opaque #29384a hairline rather than alpha over a
varying surface, which is what makes stacked surfaces read crisply on the site.

Light is derived, not inverted. The site ships one theme and never had to
answer this, but the app does: blue darkens to #2f62d8, mint to #0d8b60 and
amber to #8a5d0b, all clearing 4.5:1 on a cool paper ground, where the
dark-mode values sit near 2:1. Same three roles, different values.

Three files restate the palette because CSS variables cannot reach them:
cmTheme.js (the whole CodeMirror theme), VoiceVisualizer and WaveformPlayer
(canvas). Left alone they would have quietly kept the app half-Nord.

The `.lane` primitive replaces the near-identical row CSS that OperateOverview
and StudioOverview had each written: a full-bleed row on a hairline that insets
on hover, with no card and no shadow. Callers supply only the column template.
Both pages now use it, along with `.lane-head` for section rhythm and a
`.page-pad` container for top-level pages outside a console shell — without
which Studio sat flush against the sidebar with its eyebrow clipped.

Studio's tab strip wraps rather than running off the edge at narrow widths.

* feat(ui): put Home's resident models on lanes and give the footer one line

Home's status line was three chips saying a thing was true. It now reports
figures: how many models are resident, how many nodes are healthy, what share
of memory is in use, set in tabular monospace so the digits line up. A chip
answers whether; a figure answers how much, which is what someone opening the
page at a glance is after.

Resident models move from status chips to lanes, with the id set in a new
`.lane__name--id` because an id is something you might type or paste and the UI
face makes it read as a label. /api/system-information carries only the id, so
there is deliberately no backend or memory column: inventing one would mean a
server change this does not make.

The footer was three centred rows and cost the bottom sixth of every page for
chrome. It is one line now, version left and links right, wrapping to centred
when the viewport is too narrow to hold both. Every link it had, it keeps.

* fix(ui): correct three contrast failures and stop a guaranteed-404 poll

A contrast audit of the new palette found three values below WCAG AA, one of
which the previous commit message claimed was fine:

- White on the #4f8cff button is 3.22:1, which is large-text only. The website
  does exactly this, but a button label in an app is not large text, so the
  label goes to dark ink at 5.88:1. Light mode keeps white, which is 5.44:1 on
  its darker blue.
- Light-mode success was 4.08:1 on paper, not the 4.5 claimed. Darkened to
  #0a734f, 5.56:1.
- Nord red was already 4.28:1 on raised surfaces, a pre-existing miss carried
  over unexamined. Lifted to #c96f78, 5.02:1.

Lanes gain the two states they were missing: a 44px target on coarse pointers,
matching what EntityRail already does so the two list idioms feel the same
under a thumb, and a reduced-motion variant that keeps the background feedback
while dropping the hover inset, which is a position change.

The Operate summary no longer asks for /api/nodes on a single-node install. The
cluster API answers 503 when distributed mode is off, so it was a guaranteed
miss every fifteen seconds; it is now gated on useDistributedMode, the same
condition the rail already uses for the Nodes entry.

* fix(ui): restore the gap between overview blocks, and stop claiming zero nodes

Two defects a design review surfaced.

`.lane-head:first-child { margin-top: 0 }` was meant to stop the first block on
a page carrying a top margin. But every <section> makes its lane-head a first
child, so the reset applied to all of them and the gap between blocks vanished:
"Sections" sat flush against the attention row above it. The header supplies its
own bottom margin, so a uniform top margin is correct everywhere.

The Cluster summary read "0 nodes" on a single-node install, which looks like a
fault when the cluster API is simply switched off. It now says "Single node".

* feat(ui): open dark by default, and stop clipping the collapsed sidebar footer

Dark is the identity rather than a preference: localai.io ships one theme and
it is this one, so an install should look like LocalAI before anyone has chosen
anything. The OS setting no longer selects light on first load. The toggle
still does, and a stored choice wins forever after, which the tests assert
both ways.

The collapsed sidebar footer stacked its controls but kept the expanded row's

* feat(api): count traces server-side and give the Operate overview real totals

The overview's headline block had no source. /api/traces returns the trace
list, so "37 errors in 24h" meant fetching every buffered exchange to count it
in the browser — waste that grows with the buffer, to produce three integers.

Adds GET /api/traces/summary: totals, failures, p95 and a bucketed series for
sparklines, over a window that defaults to 24 hours and is capped at a week.

Deliberate calls, each with a spec:
- A 4xx is the caller getting it wrong, not the installation being unhealthy,
  so only 5xx and transport errors count as failures.
- p95 is a nearest-rank percentile rather than the slowest request, which is
  what a max would report and what makes latency panels lie.
- Buckets are oldest-first so a sparkline reads left to right, and the slice is
  never nil: nil serialises as null and breaks .map() on the other side, which
  is a silent runtime error rather than an empty chart.
- Exchanges outside the window are not counted at all.

The route is registered before /api/traces/:id so "summary" is not captured as
a trace ID.

On the client, Traces and Usage gain the rail signals they were shipped
without, the Observability section summary now states counts instead of listing
its destinations, and an installation that has served nothing says so rather
than showing three zeroes dressed as telemetry.

Sparkline is a bare stroke with an emphasised endpoint and no axes: the figure
above it already states the value, so its only job is the shape.

* fix(ui): stop the memory chart calling a trade-off an error

The VRAM-by-context chart rendered any build over the limit in error red, and
escalated the verdict to the error tone as soon as two context sizes crossed
it. But an over-limit build still installs — #11288 keeps a test on exactly
that — so red overstates what is happening. A model that fits at 32k and not
64k is a trade-off, not a fault.

Over-limit bars and the limit line now use the warning tone, which is the
constraint colour used everywhere else in this branch: know what you are doing,
not you may not. The error tone is reserved for "fits nowhere", where the model
genuinely cannot run on this host.

* feat(ui): give the new surfaces orchestrated motion

Uses the reveal system already in the codebase rather than adding a library:
pageReveal, .reveal-stagger and staggerStyle() were built for exactly this, and
anime.js would be ~17KB duplicating four lines of CSS for list reveals.

The overview's headline figures, attention rows and section lanes stagger in,
as do Studio's modality lanes and recent outputs, so a page assembles in the
order it is read instead of appearing all at once.

Two additions beyond stagger. Rail signals transition on opacity when a poll
lands, so a number changing reads as an update rather than a jump cut, and it
stays on the compositor so it cannot reflow the rail. The attention block
animates its left edge in — the one thing on the page that should announce
itself, and on the border rather than the text so nothing moves under a reader.

Both are dropped entirely under prefers-reduced-motion, alongside the lane
hover inset already handled.

* feat(ui): put the generators on a hairline field stack and record the request

The workbench treatment from the mocks, applied where it costs least: both
changes land on shared surfaces, so all six generators get them at once rather
than drifting apart page by page.

The control column stops being a shadowed card of boxed groups and becomes a
hairline field stack — the panel is the page's left half, not an object
floating on it — with uppercase micro-labels matching the eyebrow treatment
used elsewhere. Because .media-controls is shared, Images, Video, 3D, Speech,
Sound and Audio FX all move together.

RequestPanel shows the request the form actually built, with a copy-as-curl.
LocalAI is API-first and Studio is the best place in the app to teach its own
endpoints: the form stops being a black box, and a result worth keeping can be
reproduced from a shell without reverse-engineering which fields the page sent.
It records what was sent rather than what the form currently holds, and renders
nothing until a request has been made — a panel describing a request nobody
made is a tutorial, not a record. Wired into Images and Speech.

* feat(ui): make Chat a transcript instead of a bubble thread

Rounded, filled, asymmetric bubbles fight a system built on hairlines, and they

had already given up its bubble; this finishes the job.

Both roles now run full width down one column, separated by a rule, each with a
mono role label. The user turn keeps a left edge in the action tone so the two
are still told apart at a glance, without a fill or a corner radius. The
avatars go: the accent and the label carry the speaker, so the glyph was
decoration once neither side had a bubble.

Saying who is speaking in words rather than in geometry is also what survives
being read aloud, printed, or looked at by someone who cannot pick the sides
apart by colour.

* feat(ui): dress the API reference in LocalAI's palette

The Swagger page was the last surface still shipping in someone else's colours,
which is conspicuous now that everything it links from is dark.

Swagger UI has no theming hook, so rather than fork it we serve our own index
ahead of the library's wildcard and restate the palette over its stylesheet.
The library's own bundle and assets are still what load, so a swagger-ui
upgrade cannot silently break the page — this is a skin, not a fork.

Two things needed real care. Swagger tints the entire operation row per method
via .opblock.opblock-post and friends, so the palette had to match that
specificity rather than reach for !important; the method now lives on one edge
instead of washing across the row, because a page where every row is a status
colour has no status colour left. And the filled method chip put white on pale
green, which was the least readable thing on the page — it is an outlined mono
chip now, carrying the method in its border and text.

Palette values are copied from theme.css rather than referenced: this page is
served by Go and never sees the app's CSS. The comment says so, and says to

* fix(ui): make tall split-view pages reachable, repair the Agents header, scale titles

Three things found by actually using the app rather than measuring it.

**Host was unusable.** The shell above a split view is overflow:hidden so the
document cannot grow, which left anything taller than the viewport simply
unreachable — and Host stacks a resources card, four stat cards and a tab bar
above its split, so the bottom of the pane fell off at every window height with
nothing to scroll. Every sweep I ran for this was horizontal, which is why it
kept coming back clean.

The page now scrolls inside the pinned shell. The pane keeps its own scroller:
letting it grow instead pushes the document taller and stretches the rail to
match, which is the regression e2e/discover-height.spec.js exists to catch, and
which the first version of this fix duly caused.

**The Agents header controls were unstyled** — "Create Agent" was rendering
with the browser's default chrome. The markup had been mangled at some point:
six unrelated classes merged into one string on the link, and the label and
button left with none at all and empty icons. Repaired, with the inline flex
replaced by a shared .header-actions class.

**Page titles take the editorial scale from the site**: larger, tracked at
-0.04em, on a line height near 1, so a two-word title reads as a statement
rather than a label. The typeface is unchanged — DESIGN.md keeps the existing
type system — so the whole difference is scale, tracking and leading, which is
where the site gets its voice from. This was the biggest reason the running app
still did not look like the mocks.

Full e2e suite: 404 passed, 4 skipped.
