mudler-agentandEttore Di Giacinto 0b5cab414a feat(galleryop): limit concurrent backend operations (#12888)
* feat(config): add a limit for concurrent backend operations

Add --max-concurrent-backend-operations
(LOCALAI_MAX_CONCURRENT_BACKEND_OPERATIONS) and the runtime setting
max_concurrent_backend_operations. It sets how many backend install,
upgrade and delete operations run at the same time. The default is 1,
which keeps the current behaviour. Values below 1 become 1.

The runtime value is also kept in an atomic, so the scheduler that reads
it never races with a settings change. The setting shows in the Settings
page under Backends. This commit only adds the setting; the next one
uses it.

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

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

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

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

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

mudler-agentandEttore Di Giacinto 7c74d26555 feat(addons): run the add-on owner as its own workload (#12867)
* feat(addons): generate and load a static carrier key set

A split deployment needs the owner and the frontends to share
certificates and a signing key that outlive a process. The loopback
carrier makes fresh keys at every start, so it cannot serve that.

GenerateCarrierKeys writes a CA certificate, an owner leaf and a
frontend leaf, and the frontend signing key pair. It drops the CA key,
so nobody can issue a third leaf, and it refuses to overwrite any file.
LoadCarrierConfig reads only the files of one role and refuses key
files that group or other users can access.

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

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

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

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

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

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

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

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

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

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

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

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

* docs(addons): describe running the owner as its own workload

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

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

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

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

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

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

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

addonConfigFor already returned the zero config before it read a role

owner address, listen address or carrier directory flag is set, log one
info line that the flags are ignored. A frontend with
--addons-enabled=false needs no owner address and no key directory,
loads no keys and builds no carrier.

* feat(ui): hide add-on entries when the addons feature is off

The UI reads features.addons from /api/features. When it is false:
the sidebar shows no Add-ons entry and no pinned apps, the 404 page
lists no add-on destination, the shell does not call /api/addons/pins
or /api/addons/builtin, and /app/addons, /app/addons/*, /app/fine-tune
and /app/quantize lead back to /app. The Build hub tabs for add-ons,
fine-tuning and quantization were already keyed on features and now
follow the gate. An absent key (an older server) counts as on.

no owner address or key directory. The fine-tuning and quantization
pages say they are off with --addons-enabled=false.

* fix(addons): give a frontend no add-on state root

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

the instance is the owner, and the frontend role leaves Root empty.
Nothing on a frontend reads or creates it.

* fix(addons): make the carrier signing key optional for the owner

NewCarrier required an Ed25519 signing key of every instance, so the
owner role loaded a throwaway key in memory that it never used. The
owner never signs an outbound request, so it now needs none:
NewCarrier accepts an empty key when the instance is the owner and
still requires a whole key from a frontend, and a malformed key is
refused for both. LoadCarrierConfig no longer generates one. The owner
still verifies frontend signatures with frontend-sign.pub.

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

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

an address loads, and the address is ignored. A different owner ID or

* fix(addons): refuse library-source routes on a frontend

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

Mark the frontend role in the add-on config, also when add-ons are off.
On a frontend, LibrarySources returns the unavailable error,
ApplyLibraries does nothing and the startup step skips the store. The
six /api/library/sources routes answer 503 with the body that the add-on
feature gate writes, and an X-LocalAI-Reason header names the cause.
Reads are refused too: the carrier has no verb for them. Owner and
combined roles are unchanged.

WriteUnavailable wrote the plain text "addon request failed", and the
library-source refusal put its reason in an X-LocalAI-Reason header.

Write the LocalAI error envelope instead, with a message, a type and the
code "unavailable", and keep the 503 status. The message names the
cause: add-ons are off on this instance, the add-on owner is not
reachable, or library sources are managed on the owner. Remove the
header.

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

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

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

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

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

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

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

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

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

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

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

Replace the frontend limits that said a frontend refuses the library
routes with what happens now: the library sources and the backend
library go through the owner, the gallery lists follow the owner every
60 seconds, official_libraries is set on the owner, and the owner and
the frontends must run on one OS and architecture.

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

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

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

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

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

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

* feat(mcp): expose the backend update check as a tool

Add list_backend_library_updates, a read-only tool for
GET /backends/library/updates. The in-process client reads the
library installer, and the HTTP client calls the route. The six
library source routes stay out of the catalog: the assistant has no
per-call actor and no approval card for library changes.

* feat(api): add export status routes for fine-tuning and quantization

The add-on UIs could not know that model exports are blocked until a user
hit the refusal of the export route. Add GET /api/fine-tuning/status and
GET /api/quantization/status. Each returns {"model_exports": bool}, from
the same check that drives the model_exports key of /api/features.

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

* feat(addons): disable exports when the models probe fails

The fine-tuning and quantization pages now read the new status route

to the control. A failed or slow answer leaves the controls on, as the
server does for an unknown check.

The node is its own owner: state lives under the data path, and the

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

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

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

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

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

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

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

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

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

built bundle first: the apps list names it and its module and style
sheet are served from the build output, the way the add-on owner serves
them. studio-addon.js holds that helper, and the Studio and Talk
fixtures call it.

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

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

* fix(ui): centre the icon of a built-in tile in its icon box

The drawer drew the icon of a built-in tile (Studio's palette was one)
in a bare 40px box. Only the placeholder box was laid out as a centred
grid with the 20px size, so the real icon sat in the top-left corner at
the size of the page text.

Give the built-in tile the same classes as the placeholder box, and
check in a browser that the icon is centred.

recognition page already used. The tab is the first path segment
(voice/library), as in the Studio add-on, and the form that adds a voice

Each worker built the Studio and Talk bundles into the same dist

* fix(addons): let each add-on draw its own page title

The shell no longer titles add-on pages, so each add-on draws one h1 per
page. Voice titles its tabs "Voices" (Recognition and From a recording),
"Speech voices" (Library) and "Speak text" (Text to speech); "Add a speech
voice" already had its own. Face draws "Faces", Studio "Studio" and Talk
"Talk". Tables promotes the database list and database name from h2 to h1.
Fine-tuning and Quantization already drew a title.

The add-on unit tests and the navigation and Studio specs now assert
exactly one h1 per page, with the page's own title.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

executable bit, so the tracked files do not change. Local copies get
0600 and 0750. The library path read in mergeLibrary is the operator's
own argument, so that read is annotated.

feat(backends): --disable-backend-install refuses every backend acquisition

A hardening switch for deployments that must run exactly the backend set they
were tested with (production, air-gapped, immutable images, package-managed
hosts). With LOCALAI_DISABLE_BACKEND_INSTALL=1 every install and upgrade path
refuses — gallery, OCI/URL/path, node-scoped, auto-upgrade, boot-time external
backends — HTTP routes answer 403 up front, and a model whose backend is
missing is refused before any download: 409 on the API, an error on preload
and import. Whether a backend is present is asked of the execution target:
the local backend directory on a single node, the workers' listings on a
distributed frontend, which installs nothing itself. Backends already
present, including system-path ones, keep working.

mudler-agentandEttore Di Giacinto e45dc5e9f7 feat(addons): installable add-ons foundation and the Tables add-on (#12702)
* feat(addons): add the add-on runtime, navigation and first-party add-ons

Add the add-on runtime to LocalAI: manifests, the host operation broker,
admin gating by account role, the add-on UI bundle builder and the SDK
for add-on pages. Move the navigation to Chat, Models, Add-ons and
Settings, with pinned add-ons in the sidebar and an Add-ons drawer.

Ship the first-party add-ons (voice, face, fine-tuning, quantization) as
packages for linux/amd64, linux/arm64 and darwin/arm64. Intel macOS
(darwin/amd64) is enabled in the platform files.

Squashed from the review branch. The tree is unchanged; the pre-squash
history is kept on a local backup branch.

mutations to the owner for any administrator key, which skipped the
browser-session rule of their own routes. Refuse those actions

not only the session cookie, because the global CSRF check lets
same-site requests through.

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

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

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

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

* fix(addons): keep the loopback owner address stable across restarts

The single-node loopback transport took a new ephemeral port at each
start. The owner stores its address in its identity file and refuses to
start when the address differs, so every start after the first failed
with "invalid addon owner configuration".

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* fix(ui): centre the icon of a built-in tile in its icon box

The drawer drew the icon of a built-in tile (Studio's palette was one)
in a bare 40px box. Only the placeholder box was laid out as a centred
grid with the 20px size, so the real icon sat in the top-left corner at
the size of the page text.

Give the built-in tile the same classes as the placeholder box, and
check in a browser that the icon is centred.

On the first start, when the owner has no sources.json, register the

* test(ui): wait for the target node's Reinstall button after the popstate

The "generic deletion blocks targeted install at confirmation" spec
dispatches a popstate to set the target node, then waits for a button
named Reinstall and clicks it. Until React renders the targeted page,
the page still draws the generic Reinstall button. It is enabled and has
the same name, so the wait passed on it, the click started a global
install, and no node install request was sent. The poll on the install
count timed out with the confirm dialog still open.

With the CPU throttled to 8x, the spec failed on 20 of 20 runs, and the
button it clicked had the title "Reinstall". The spec now waits for the
button titled "Reinstall on <node>". With the throttle it passes 30 of
30 runs. The assertions are unchanged.

* test(ui): give the Studio hand-off spec a budget for the cold bundle load

The "a result made through a hand-off records which result it came from"
spec opens the Studio add-on straight from an address, twice. Each is a
cold load: the page shows "Loading" until the add-on module has run, and
the next assertion had the default five seconds. The load takes about
two seconds on an idle run and seven to ten under CPU load, so the spec
failed on a loaded machine with the hand-off note not yet drawn.

With the CPU throttled to 6x and eight busy loops running, it failed on
21 of 30 runs. The first assertion after each load now waits up to 20
seconds, and the spec then passed 30 of 30 under the same load. The
assertions are unchanged.

* fix(addons): carry the identity page styles in the Face add-on

The Face page is drawn with the shared identity views, but its style sheet
held only the clip and error rules. The page, card, model list, known-faces
table, enrol sheet and distance scale classes had no rules. They looked
right only when the host had already loaded the style sheet of its own
Faces page, which a visit through the add-on drawer does not do. Opened
that way, the cards had no gap, the model list showed bullets, and the
install buttons ran into the names.

The Face sheet now holds the same identity rules as the core sheet, so the
page looks the same whichever way it is opened.

The test reads the redirected URL right after the path changes. The

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

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

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

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

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

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

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

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

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

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

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

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

and no state a person could see. The chat header now has an Add-ons button
in the style of the MCP dropdown. It lists each running add-on that ships
tools with a switch, and a badge shows how many are on.

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

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

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

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

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

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

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

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

* fix(ci): capture and surface ginkgo errors in run-coverage.sh

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

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

The build flags (--tags, --coverpkg) are quoted correctly so values

eval.

mudler-agentandEttore Di Giacinto 0e0e91f95c feat(diagnostics): add opt-in profiling (#12610)
* feat(diagnostics): add private opt-in profiler

Keep profiling on a dedicated loopback listener rather than the public API.
Validate settings and bind synchronously so startup reports configuration
and socket failures. Own sampling and shutdown for the run process.

Cover private handlers, blocked cmdline access, sampling cleanup, and
serving failures with focused Ginkgo tests.

Assisted-by: nib:gpt-6-astra

* feat(diagnostics): add sanitized phase timing

Carry generated request and reload identities through private contexts.
Keep timing disabled without allocations and emit only validated fields
at Info level when enabled.

Cover identity isolation, nested durations, inheritance, and sanitized
logging with focused race-tested Ginkgo specs.

Assisted-by: nib:gpt-6-astra

* fix(diagnostics): retain request observations

Reuse an existing request observation across recorders to avoid splitting
correlation. Keep the original context, identity, and sink without new
allocations. Preserve nil-recorder behavior and fresh reload identities.

Verify the regression fails before the fix and passes with the full
Diagnostics race suite afterward.

Assisted-by: nib:gpt-6-astra

* feat(cli): own opt-in diagnostics lifecycle

Expose profiling and phase timing flags without enabling them for debug.
Bind the private profiler before application initialization and propagate
serving failures through the run lifecycle.

Bound signal cleanup and preserve preload-only backend startup. Cover
flag parsing, preload isolation, cancellation, and once-only shutdown.
Document initialization and shutdown cancellation limitations.

Assisted-by: nib:gpt-6-astra

* feat(config): measure filter and reload phases

Separate request lock waits from filtering and held work. Aggregate reload
filesystem and parsing durations without logging inside the config lock.

Preserve caller option execution under the lock after metadata collection.
Extract only the internal diagnostics option before waiting for the lock.
Keep direct callers uninstrumented unless they supply diagnostics options.

Verify focused Diagnostics examples with the race detector, including
option ordering, gated contention, errors, panic propagation, and parity.

Assisted-by: nib:gpt-6-astra

* fix(config): separate early reload observation

Opaque callbacks cannot select timing before their execution point.
Carry the startup recorder explicitly through loader construction.
Apply late options once under the lock and honor composed last writes.
Document early and late phase boundaries and observation identities.

Report malformed gallery syntax as an internal parse failure without
changing strict or non-strict loader returns.

Assisted-by: nib:gpt-6-astra

* fix(config): preserve per-model option callbacks

The resolved snapshot suppresses existing callbacks during model defaults,
even when diagnostics are disabled. Pass original options through the
existing defaults pathway without adding diagnostics-driven replay.

Test stateful options with two models in enabled and disabled modes.
Preserve three calls and thread defaults of two and three.

Assisted-by: nib:gpt-6-astra

* feat(model): observe discovery phases

Carry request diagnostics through config and loose-file discovery to
separate directory enumeration from in-memory filtering and fallback.
Keep existing APIs as background-context wrappers and preserve discovery
policies, ordering, duplicates, errors, and filesystem operation counts.

Add focused parity, privacy, phase, and disabled-allocation tests.
The focused diagnostics race gate passes for model and galleryop.

Assisted-by: nib:gpt-6-astra

* feat(http): observe extraction phases

Generate diagnostic identity before request discovery, independently of
client correlation headers. End each extraction segment before inference
so downstream latency does not inflate discovery measurements.

Carry observations through discovery helpers and rebuilt request contexts
without changing cancellation or model selection. Cover disabled parity,
error outcomes, privacy, concurrent identity isolation and route contexts.

Assisted-by: nib:gpt-6-astra

* fix(http): retain diagnostics across failover

Failover restores its entry request before retrying. Initialize the
observation before that capture so direct extraction retains one ID.
Keep extraction spans per attempt and end them before downstream work.

Exercise two real targets without default middleware, including replay,
shared identity, phase boundaries, and timing-off response parity.

Assisted-by: nib:gpt-6-astra

* feat(model): observe initialization and routing

Mark loader entry before cache and admission checks. Measure only the
ModelRouter callback, without attributing transport or worker latency.

Test inherited identity and sanitized events with fake backends. Exercise
the actual Echo router to keep profiles private across debug and timing
options. Cover capture shutdown, forced close, and lifecycle failures.

Assisted-by: nib:gpt-6-astra

* docs(diagnostics): guide bounded investigations

Document private profiling, sampling ownership, and phase boundaries so
operators can interpret captures without assuming request attribution.
Add Ginkgo drift checks for flags, defaults, phases, links, and capture
warnings. These checks do not certify the operator prose.

The focused documentation race test passes after four expected failures.
The consolidated Diagnostics race gate passes across all eight packages.
This gate does not validate the full suite, auth, or production UI.

Assisted-by: nib:gpt-6-astra

* refactor(cli): restore inline run lifecycle

Remove diagnostic startup hooks so application startup stays readable
in Run. Keep the profiler as an optional sidecar with bounded cleanup
and an error watcher, without a general lifecycle runner.

capture tests. Document that application cleanup can exceed the
private listener budget.

The eight-package Diagnostics race gate passes. A cleanup mutation
fails the real CLI listener-release regression as expected.

* fix(cli): retain concurrent startup errors

Cancellation must not hide a public API bind failure. Join the public
serve result, cancellation cause, and HTTP shutdown errors inline.

listener. Isolate the Linux socket fixture in a subprocess and wait
for cancellation acknowledgment without timing sleeps.

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

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

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

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

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

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

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

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

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

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

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

Problem:
- the image tar and its compressed layers staged in os.TempDir()
- /tmp is commonly a RAM-backed tmpfs far smaller than a backend image

Change:
- staging path resolved like the other storage paths

- every download works in its own subdirectory holding its tar and

237cf456fd feat(gallery): galleries published as OCI artifacts (#12167)
* feat(oci): pull ORAS artifacts into a directory

Galleries published to an OCI registry arrive as an ORAS artifact whose
layers carry their tree path in org.opencontainers.image.title. Nothing in
pkg/oci could read a non-image manifest, so add PullArtifact: it lays the
layers out under a destination directory and returns the manifest digest so
callers can pin and verify signatures on it.

A registry is remote input and this writes files, so the manifest is
validated before any byte is fetched. A title that is absolute, escapes the
destination or is missing is refused, an artifact of an unexpected
artifactType is refused, and both the layer count and the total size are
capped with caller-settable limits.

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

* feat(gallery): fetch and verify galleries published as OCI artifacts

A gallery whose URL is oci://host/repo:tag is now pulled as an ORAS
artifact and its index.yaml read from the unpacked tree, alongside the
existing HTTP and file sources. Mirrors, the per-candidate timeout, the
failure cooldown and the last known good copy work the same for both
schemes, so a gallery can mirror an OCI primary with an HTTP fallback.

When the gallery declares a verification policy the artifact reference is
resolved to its manifest digest, the publisher signature is checked
against that digest, and only then is the same digest pulled. Nothing
unverified is written to disk or parsed. With strict integrity mode on,
an OCI gallery without a verification policy is refused instead of
warned about, which is what the flag already does for backend installs.

The pull lands in a staging directory that is renamed into the cache only
once the whole tree is on disk and the index reads back as an index, so a
failed or interrupted pull leaves nothing a later fetch would serve. A
fetch that finds a fresh cache entry does not contact the registry.

* feat(gallery): resolve entry urls relative to the gallery root

A gallery published as a self-contained tree, which is what an OCI
gallery is, names its base configs by their place in that tree. Such a
url reached the HTTP client verbatim and no entry of the gallery could
be installed.

A scheme-less entry url now resolves against the root the index came
from: the unpacked artifact for an oci:// gallery, and the directory of
the index URL otherwise. The relative path may not climb out of that
root, reusing the guard the artifact puller already applies to layer
titles, and an entry that does is dropped from the listing rather than
failing the whole gallery. An entry that names its own scheme is
untouched, so .ref indirection and local github: resolution behave as
before.

Reading an entry of an OCI gallery also needs the unpacked artifact
directory as its trusted root, since the cache is deliberately a sibling
of the models directory the downloader otherwise confines a file read
to.

query string or fragment is refused because it can never apply and a query

AuthError now appends its cause, so a registry's DENIED or UNAUTHORIZED
detail reaches the operator. HTTP auth errors print only the status text in
place of the cause, because the downloader builds that cause from the
requested URL, which can carry a signed query string. Registry pulls say
that docker config credentials were tried too, and a download that carried
a caller-provided credential (WithBearerToken, or an explicit authorization
on gallery reads) reports that credential as rejected instead of blaming
the store.

The Range probe for a leftover partial file now returns an unresolved

closes the request body when a rule's secret cannot be resolved, as the
RoundTripper contract requires. The redirect spec now uses a custom header
rule on the origin, which net/http would not strip on its own, to prove the

localai-org-maint-botandEttore Di Giacinto 9afe10ba21 fix(distributed): survive a slow control-plane database (#11837)
* fix(distributed): evict only when a node is known to be full

scheduleNewModel asked the registry for a free replica slot and treated
every error as "this node is full", so a control-plane database slow
enough to time out the lookup evicted a healthy loaded model. The
evicted process died, a peer frontend still holding its address dialled
the dead port and retried, and the model thrashed between nodes. The
comment on the branch already said it meant a full node; the code never
tested for it.

Evict only on ErrNoFreeSlot. Any other error now returns and names the
lookup that failed, so a slow database degrades into a diagnosable
load failure instead of into lost work.

An audit of the rest of the router found one branch of the same shape:
node selection discarded the error from its last-resort finder, so a
database timeout there also produced a nil node and evicted for it.
That path now returns unless the finder said gorm.ErrRecordNotFound,
which is the only answer that means the cluster had no node to give.
No other destructive branch in router.go fires on a generic error.

* fix(distributed): checkpoint heartbeat writes instead of writing every beat

Every heartbeat UPDATEd backend_nodes. Six nodes at a ten second beat is
roughly 52,000 writes a day against a six-row table, and that churn is
what turned a blocked autovacuum into a 460 MB table whose six-row scan
cost 867 ms and timed out the queries that place models.

A beat carrying only a fresher timestamp now waits for the checkpoint
interval. Each reported field is compared against the value last
persisted rather than tested for presence, because a worker sends its
disk figures on every beat and presence alone would suppress nothing.
A node's first beat, a changed total VRAM, total disk or GPU vendor,
and a free VRAM, RAM or disk reading that has moved more than 256 MiB
from the persisted value all still write at once. A node that is not
active is never suppressed, because it recovers only when the health
monitor sees a fresh timestamp.

The persisted column is up to one interval stale by design, so the
stale-node threshold moves from 60s to 5m to cover it.

* fix(distributed): fail worker readiness when a held backend is unreachable

The readiness gate tracked only the NATS link, so a worker whose backend
processes had died still answered /readyz with 200 and kept receiving
loads. One node did exactly that during an incident: it reported healthy
while its backend port refused connections, and every load routed to it
failed.

Readiness is now the NATS link and, for each backend process the worker
believes it is running, a short dial of its recorded address. A worker
holding no backends stays ready, because idle is a healthy state.

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

* fix(distributed): keep a starting backend out of the readiness dial set

A backend process is inserted into the supervisor map with its gRPC
address already recorded, but the address refuses connections until the
gRPC server binds, which the startup poll allows up to 30 seconds for and
which takes 10 to 15 seconds on a slow node. The new data-path readiness
probe dialled that address straight away, so a worker answered /readyz
with 503 for the whole of every cold backend start. The container
HEALTHCHECK absorbs that, but a Kubernetes readinessProbe at 10s does
not, and the worker would leave rotation each time it loaded a model.

The skip for a stopping process had no counterpart at the other end of
the lifecycle. Backend processes now carry a serving flag, set where the
startup health-check gate succeeds, and the probe dials only processes
that are serving and not yet stopping. backendStartStillValid becomes
markBackendServing: the check and the mark must share one lock hold, so
the flag can only ever land on the entry the key currently owns.

* feat(distributed): export control-plane database health gauges

Four transactions wedged on a corrupt index held the vacuum horizon open
for 42 days. Nothing measured it, so the first symptom anyone saw was
models failing to load six weeks later, by which time a six-row table
had grown to 460 MB.

Export the oldest xmin age, the longest open transaction, and the dead
tuple ratio on the registry tables. The first is the number that would
have caught it: it sits near zero in health and was 21,002,291.

Sampling is scrape-driven behind a cache, and a failed sample reports
the last good values rather than failing the scrape, because these
gauges matter most when the database is already struggling.

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

* fix(distributed): rate-limit failed control-plane database samples

The cache advanced its clock only on a successful sample, so once the
database started failing every scrape retried the query immediately.
That turned the cache off in the one regime it exists for: a retry
storm at scrape cadence aimed at a database already in trouble. A
catalog read that consistently exceeds the 5 second timeout also paid
that cost on every scrape, with all scrapes serialised behind the
sampler mutex.

Time every attempt rather than every success, so failures and timeouts
cost the same interval as good samples. Whether a good sample exists
moves to its own field, keeping the gauges absent until the first
success and holding the last good values through later failures.

Also note in the runbook that pg_stat_activity cannot see prepared
transactions or replication slot xmins, so a healthy-looking xmin age
does not by itself rule out a blocked horizon.

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

* test(distributed): pin that a failing database evicts nothing

Exercises the real distributed stack against a control-plane database that
refuses the router's slot lookup, and asserts the scheduler reports the
lookup it could not answer instead of falling through to eviction.

The failure is injected with privileges rather than a statement timeout. A
timeout set with ALTER DATABASE also breaks AutoMigrate, and it leaks into
every later spec in the suite unless it is reset, so the spec would end up
testing the migration rather than the scheduler. Instead the spec creates a
dedicated login role, points a second gorm handle at it, and revokes that
role's SELECT on node_models.replica_index. This has to be a separate role:
the test container's owner is a PostgreSQL superuser, and superusers bypass
every privilege check, so revoking from CURRENT_USER is recorded and then
ignored.

The revoke is scoped to one column on purpose. Revoking the whole table
would also blind node selection, which runs first and has a guard of its
own, so the scheduler would never reach the slot lookup this spec is about.
Leaving every other column readable lets selection succeed and lands the
refusal exactly on NextFreeReplicaIndex, which plucks replica_index. The
grant is restored from BeforeEach via DeferCleanup, so a failing assertion
or a panic cannot hand the next spec a role that cannot read.

Reverting the eviction guard fails this spec, which is the point of it: the
router then reports "no replica slot on keeper and eviction failed" for an
error that was never evidence the node was full. The surviving-row
assertions are secondary under this injection, because the eviction path
reads whole node_models rows and the same revoke blinds it too; a comment
in the spec says so, so nobody mistakes them for the load-bearing ones.

Also documents why the vector store and the control plane must not share a
database: the removable-tuple cutoff is per database, not per table, so one
transaction left open anywhere stops autovacuum reclaiming the node
registry, and a six-row table bloats into hundreds of megabytes. The note
names LOCALAI_AUTH_DATABASE_URL and LOCALAI_AGENT_POOL_DATABASE_URL as the
two knobs that must differ, and the localai_control_plane_oldest_xmin_age
gauge as the way to see it coming.

grep for StaleNodeThreshold and HealthCheckInterval in
core/config/runtime_settings_registry.go returns no matches: the
distributed duration knobs are not exposed as runtime settings, so the new
heartbeat checkpoint interval follows them and needs no registry entry.

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

* fix(distributed): close the review gaps in the heartbeat and health path

The stale-node threshold moved from 60 seconds to 5 minutes in this branch
because checkpointing makes last_heartbeat up to one checkpoint interval
behind by design. Two things were left inconsistent with that. NewHealthMonitor
still fell back to a hardcoded 60 seconds when handed a zero threshold, so any
future caller that stopped passing the configured value would mark every
healthy, beating node offline on every cycle. And the threshold itself had a
flag-name constant but no AppOption, no CLI field and no env binding, so an
operator who widened --node-heartbeat-checkpoint had no way to widen the
threshold to match. The fallback now tracks config.DefaultStaleNodeThreshold,
and --stale-node-threshold / LOCALAI_STALE_NODE_THRESHOLD is wired the same
way its sibling is.

Heartbeat suppression compared the RAW reported free VRAM against the
snapshot, but the column persists capAvailable(raw, ceiling). On any node with
a VRAM budget set, whose actual free VRAM oscillates above that ceiling, every
beat looked material while the persisted value never moved: suppression was
defeated on exactly the nodes an operator had configured, and the write
amplification this branch exists to remove came straight back there. The
comparison and the snapshot now both hold the capped figure, so they measure
the same quantity as the column.

Fixing that needs the ceiling, and reading it cost a SELECT on every beat,
including suppressed ones. The skip decision therefore moved ahead of the
updates map and now reuses the ceiling cached on the last durable write, while
the write path still re-reads it before capping anything. A ceiling that
changed inside the checkpoint window can cost one extra or one late write; it
cannot persist a wrong figure. A suppressed beat now costs no query at all.

Also: the operations section now says to grant pg_read_all_stats to the
LocalAI role, because PostgreSQL blanks backend_xmin and xact_start for
sessions owned by other roles, and the transaction that wedged the horizon in
the incident was a co-located vector store connecting as a different role, so
without the grant the new gauge sees only our own sessions. The compose
healthcheck comment now describes readiness covering the backend data path,
and the control-plane gauge registration records the otel.SetMeterProvider
ordering it depends on.

* fix(distributed): resolve the gauge's table names through gorm

The dead-tuple gauge queried pg_stat_user_tables against a hardcoded list
of three table names. Those three do not agree on where their name comes
from: BackendNode and NodeModel take gorm's default pluralisation, while
GalleryOperationRecord overrides TableName, and gallery_operations
already had a constant of its own that the list duplicated.

A literal list keeps compiling after any of that moves, and the query
then matches nothing. The failure is silent and it points the wrong way:
a dead-tuple ratio that matched no rows reports the same numbers as a
cluster with no bloat, so the gauge would look healthiest exactly when it
had stopped working.

Ask gorm what each model is stored as instead, which follows a TableName
override and the default pluralisation alike. A spec pins that the
override really is consulted: naive pluralisation of the type would give
gallery_operation_records, so the resolution cannot quietly stop asking
the model.

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.

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

* 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.

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

* 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.

Adiraandlocalai-org-maint-bot ab52813342 feat(modelartifacts): support bounded parallel Hugging Face file downloads (#11162)
* feat(modelartifacts): support bounded parallel Hugging Face file downloads

Closes #11114.

Snapshot materialization fetched every file through the sequential
executor in DownloadFilesWithContext, so a repository split into many
shards spent most of its wall clock in per-file request latency rather
than moving bytes.

Add DownloadFilesWithConcurrency, an errgroup with SetLimit, and keep
DownloadFilesWithContext as a wrapper that passes a limit of 1. That
leaves the two non-artifact callers (core/gallery and the model config
loader) on exactly the path they had: tasks still run in slice order,
and the first failure still returns before any later task starts.

Only whole files run in parallel. A single file is never split, so the
.partial resume machinery and the per-file SHA check in
downloadTaskWithRetry are untouched.

Two details the parallel path forced:

- completedBytes becomes an atomic.Int64. Several AfterDownload hooks
  add to it while other files' progress callbacks read it; without this
  the race detector reports three races on the new specs.
- The caller's status callback is serialized. The sequential path gave
  it an implicit guarantee of never being entered twice at once, and it
  belongs to the caller, so the executor keeps that promise rather than
  pushing locking onto every caller. AfterDownload is deliberately not
  serialized -- it does the verify-and-promote work that parallelism
  exists to overlap.

Manifest order needed no work: each hook already writes its own
manifest.Files slot by snapshot index, so entries stay in snapshot
order whatever the completion order. A spec now pins that.

The default is 1, unchanged behaviour. A shared models volume is often
the bottleneck rather than the link, so raising it is a deployment
decision; --artifact-download-concurrency and
LOCALAI_ARTIFACT_DOWNLOAD_CONCURRENCY expose it on both `run` and
`models install`.

Not done here, per the issue: no chunk-level parallelism within a single
file, and no throughput measurements across concurrency 1/2/4/8 -- that
needs a representative sharded repo and a real link.

* feat(modelartifacts): expose download concurrency in settings

Follow-up to review feedback on #11162:

- The CLI flag and docs no longer describe the limit as Hugging Face
  specific. It applies to any artifact source, as @mudler pointed out.
- artifact_download_concurrency is now a persisted runtime setting and
  is editable from the WebUI, so it can be changed without a restart.

The manager's limit becomes an atomic.Int64 behind
SetDownloadConcurrency, because a live runtime setting can be updated
while a materialization is already in flight. Injected materializers
stay compatible through an optional setter interface, so a manager that
does not implement it is simply left alone.

Verified before taking this on: go build, go vet and go test -race all
pass for pkg/modelartifacts, pkg/downloader and core/config. The React
UI builds with vite, artifact_download_concurrency is present in the
built Settings chunk, and eslint reports the same 8 pre-existing
warnings on Settings.jsx as it does without the change.

Implementation contributed by localai-org-maint-bot on the review
thread; reviewed, verified and signed off by me.

mudler's LocalAI [bot]andEttore Di Giacinto 6584db992f fix(nodes): never schedule a model onto a node that cannot store it (#11054)
* fix(nodes): never schedule a model onto a node that cannot store it

A worker whose models filesystem was 100% full kept advertising
`status: healthy`, stayed a scheduling candidate, was picked to host a
70 GB video model, accepted the staging request, transferred ~17 GB and
only then failed:

  staging .../whisper-large-v3/model.fp32-00001-of-00002.safetensors:
    upload to node b7bacbf4-... failed with status 500:
    writing file: /models/longcat-video-avatar-1.5/...: no space left on device

The node was at 937G/937G/0-avail. Total elapsed before the truth
surfaced: 16 minutes, for a decision that could never have succeeded.

The worker health signal only ever proved liveness. `/readyz`
(WorkerReadiness/NATSReadiness) checks the NATS link; `status: healthy`
in the registry is driven by heartbeat recency. Node capacity carried
VRAM and RAM but no disk figure at all, and the router compared model
size against VRAM only — nothing anywhere looked at free space on the
filesystem that staging actually writes to.

Report it, then use it:

- Workers now measure the filesystem backing their MODELS directory
  (not `/` -- staged weights land in the models path, and that mount is
  very often separate) and report `total_disk`/`available_disk` on
  registration and on every heartbeat. Free disk moves faster than VRAM
  under staging traffic, so the per-heartbeat refresh matters.
- The SmartRouter drops nodes that cannot store the model before it
  picks one. The requirement comes from `modelPayloadBytes` -- the same
  local paths `stageModelFiles` uploads, already computed for the
  size-derived load budget -- plus a 5% / 1 GiB margin, rather than a
  fixed percentage of the node's disk. A percentage threshold would take
  a small-but-usable node out of rotation for models it could hold, and
  on a homogeneous cluster would strand every node at once.
- When no node fits, scheduling fails immediately with an error naming
  the requirement and each node's free space, instead of picking one and
  discovering it mid-transfer.

Two deliberate non-changes. Low disk does not mark a node `unhealthy`:
the check is per model, so a node too small for one model stays a valid
target for smaller ones. And `total_disk == 0` means "does not report
disk" (pre-upgrade worker, or a failed stat), not "full" -- such nodes
pass through untouched so a rolling upgrade never empties the candidate
pool. A genuinely full node is distinguishable: non-zero total, zero
available. Registry read failures are logged and scheduling continues
unfiltered; a database hiccup must not wedge a cluster.

Free space is surfaced on the node detail page next to VRAM, since the
incident's signature was a node that looked entirely healthy.

* feat(nodes): make the disk-headroom check operator-controllable

The admission check added in the previous commit had no off switch. A
scheduler-side veto with no escape hatch is a liability: our size
estimate can be wrong (deduplicating or compressing filesystems, a
backend that fetches its own weights rather than loading the staged
copy), and an operator who hits that has no way out but a downgrade.

Add one knob with two surfaces that share a single source of truth:

- `--distributed-disk-headroom-check` / `LOCALAI_DISTRIBUTED_DISK_HEADROOM_CHECK`
  (default true), following the `--distributed-prefix-cache` pattern for
  a default-on distributed feature.
- `distributed_disk_headroom_check` in the runtime-settings registry, so
  it can be flipped without a restart from `POST /api/settings` and from
  Settings -> Distributed in the WebUI.

Both write `DistributedConfig.DiskHeadroomDisabled`, and the SmartRouter
reads that member LIVE on every scheduling decision through a closure
over the application config rather than a value snapshotted at
construction. Env/CLI sets the boot value, the runtime setting overrides
it live, last write wins, and there is exactly one member to read.
Snapshotting would have made the runtime toggle a no-op until restart.

Disabled means WARN, not SKIP. Selection goes back to ignoring free disk
-- byte for byte the pre-check behaviour -- but the check still runs, and
when it would have rejected every node it says so, naming the knob that
suppressed it. Going quiet when switched off would reproduce the exact
condition that made the original incident expensive: a cluster doing
something that could not work and saying nothing. Disabling is also
logged once at startup. Warning only on the total-rejection case keeps
it actionable rather than chatty on a heterogeneous cluster.

Also fixes a false positive in the check itself: shared-models mode
(LOCALAI_DISTRIBUTED_SHARED_MODELS) stages nothing at all -- every node
already mounts this models directory at this path -- so demanding the
full checkpoint size of free space per node would have rejected a
cluster that needs no new bytes. The check is skipped there entirely.

mudler's LocalAI [bot]andEttore Di Giacinto ff299df453 perf(http): gzip responses, cache hashed assets, bound the trace endpoints (#11056)
Three measured HTTP-layer regressions on a live deployment, fixed together
because they all shape the bytes on the wire.

1. No compression. The server sent no Content-Encoding regardless of what
   the client asked for, confirmed with curl straight at 127.0.0.1:8080 so
   it was not an ingress artefact. Adds gzip middleware, on by default and
   configurable via LOCALAI_DISABLE_HTTP_COMPRESSION and
   LOCALAI_HTTP_COMPRESSION_MIN_LENGTH (default 1024 bytes so tiny bodies
   are not wastefully wrapped). Streaming routes are skipped explicitly:
   an SSE Accept header, a WebSocket upgrade, and the completion / SSE /
   log-tail path prefixes, because whether a completion request streams is
   decided by the request body, which the middleware runs too early to see.
   Already-compressed formats (woff2, png, mp4, ...) are skipped too; gzip
   made those marginally larger. Measured over the embedded React build:
   JS+CSS 2815 KB raw to 808 KB gzipped (3.48x).

2. No cache headers on content-hashed assets. Vite hashes the filenames,
   so a given /assets/ URL can never change content, yet they shipped with
   no Cache-Control, ETag or Last-Modified, and the browser re-fetched the
   whole bundle on every navigation with no conditional request available.
   /assets/* now carries public, max-age=31536000, immutable. index.html
   stays no-cache so a deploy is picked up, and the unhashed locale JSONs
   get a short TTL rather than the immutable one.

3. Unbounded trace endpoints. /api/traces returned 21,033,606 bytes in
   4.65s and /api/backend-traces 3,471,682 bytes in 1.50s, and the admin
   UI polls both every few seconds. The ring buffer holds up to 1024
   entries, each embedding full input_text payloads. Both list endpoints
   now take limit / offset / full, default to 50 entries, and strip the
   heavy fields (request and response bodies plus headers for API traces,
   body and data for backend traces) unless full=true. Every trace gets a
   process-lifetime ID and GET /api/traces/{id} and
   /api/backend-traces/{id} serve the full record, which is what the UI
   fetches when a row is expanded. The list body stays a JSON array;
   paging metadata rides in X-Total-Count, X-Trace-Offset and
   X-Trace-Limit. Reproducing the live shape in a test, the polled payload
   goes from 21,131,097 bytes to 7,201 bytes.

mudler's LocalAI [bot]andEttore Di Giacinto 01fca9c9b2 fix(distributed): scale the remote model-load deadline with checkpoint size (#11030)
The gRPC deadline for the remote LoadModel call was a fixed 5m. It starts
only after the backend install and file staging have completed, so it
covers the worker's checkpoint read and pipeline init alone - work whose
duration is proportional to the bytes on disk. A fixed value is therefore
a model-size cliff, not a timeout.

Measured in production: a 70 GB video checkpoint (longcat-video-avatar-1.5)
on an NVIDIA Jetson Thor worker failed reproducibly with
"rpc error: code = DeadlineExceeded" after 953.5s of wall clock. Backend
install plus staging consumed ~11m, then LoadModel got its 5m and expired.
The load never had a chance, and the operator saw only a generic
DeadlineExceeded with no hint that a config value was the cause.

Raising the constant does not fix this. It moves the cliff to the next
larger model - the cluster has to support 600 GB checkpoints - and it makes
a genuinely wedged SMALL model hang for the whole inflated duration before
anyone notices, which is a real regression in failure latency.

So derive the budget from the checkpoint size instead:

    budget = 5m + 20s/GiB, capped at 6h

2 GiB -> 5m40s, 70 GiB -> 28m20s, 600 GiB -> 3h25m. The per-GiB rate is
deliberately pessimistic (~54 MB/s of weight read) because the errors are
not symmetric: too long costs only failure latency on a load that was going
to fail anyway, too short is a guaranteed false failure on a healthy load.

The size is measured from the frontend's local model files, over the same
path set stageModelFiles uploads. When those files are not present locally -
a backend handed a bare HuggingFace repo id fetches its own weights on the
worker - there is nothing to measure and the budget stays at today's 5m.

An explicit LOCALAI_NATS_MODEL_LOAD_TIMEOUT still wins outright, in both
directions: a shorter override is honoured, so an operator who wants fast
failure is not silently extended by the heuristic.

The cold-load hold needed widening to match. It extends on staging progress,
but LoadModel reports none, so once the last byte lands the hold expires a
stall window later and would cancel a load still well inside its own budget.
scheduleAndLoad now extends the hold by the load budget plus the staging
margin as it enters the load phase; ModelLoadCeilingFor stays the hold's
starting budget rather than its maximum.

Finally, a deadline that does expire now names the budget, the checkpoint
size it was derived from, and the knob that overrides it, instead of
surfacing a bare "context deadline exceeded".

mudler's LocalAI [bot]andEttore Di Giacinto fb4c61d1c9 fix(distributed): configurable remote model-load timeout, and reap the load when it times out (#10948)
* fix(distributed): make the remote LoadModel deadline configurable

The router hardcoded a 5 minute gRPC deadline for the remote LoadModel
call. Staging finishes before the timer starts, so those five minutes
cover only the worker backend's own checkpoint load and pipeline init.
A cold load of meituan-longcat/LongCat-Video-Avatar-1.5 (~83 GB) on an
ARM64 Thor worker fails at exactly 302s with DeadlineExceeded while the
backend process is still making progress (CPU time accumulating, RSS
moving as weights are mapped), so the load was cut short rather than
wedged.

Add LOCALAI_NATS_MODEL_LOAD_TIMEOUT / --model-load-timeout mirroring the
existing backend-install timeout knob, defaulting to 5m so unset
clusters keep today's behaviour.

The cold-load hold ceiling (which bounds how long one load may hold the
per-model advisory lock) was derived from the install timeout alone, so
raising the load deadline past it would have been silently clipped.
Derive it from both budgets via ModelLoadCeilingFor:

    max(install + load + 5m staging margin, 25m)

With the defaults that is 15m + 5m + 5m = 25m, identical to the previous
constant, and the 25m floor means shrinking either budget can never
tighten the ceiling below what clusters relied on before.

* fix(distributed): reap the abandoned replica when a remote load times out

The gRPC deadline on the remote LoadModel call only cancels the client
side. A backend blocked in a synchronous weight load never observes its
cancelled handler context, so when scheduleAndLoad gave up it left the
worker loading with nobody waiting for the result.

Observed on an ARM64 Thor worker loading LongCat-Video-Avatar-1.5: the
client returned DeadlineExceeded at 302s, and the backend process was
still alive 30 minutes later having pulled ~57GB from HuggingFace. Every
retry stacked another multi-GB loader on the worker; they had to be
reaped by hand via POST /api/nodes/:id/models/unload.

Send backend.stop for the exact `modelID#replicaIndex` process key we
just abandoned. The exact key matters: a bare model ID stops every
replica on that node, including healthy ones serving traffic.

Only a deadline or cancellation triggers the reap. Any other LoadModel
failure is the backend answering, which means its handler returned and
the process is idle - stopping it there would discard a warm process and
its downloaded weights. The reap is best-effort and never replaces the
load error the caller is waiting on.

The `modelID#replicaIndex` format was already hand-rolled in two places
(the worker's buildProcessKey and pkg/model's log store). Rather than add
a third, export model.BackendProcessKey from pkg/model, the lowest common
dependency of both sides.

and enforces the budget uniformly (Task 6).

Also closes a Task 6 gap: on re-registration, a struct Updates zero-skips
an empty budget, so a worker that dropped LOCALAI_VRAM_BUDGET left the
stale cap in place. For non-admin-override nodes the budget columns are
now force-written (map Updates) even when empty, so removing the env var
clears the cap; admin overrides are preserved unchanged.

budget a second time. For an absolute budget this is idempotent, but for
a percentage budget b.Apply resolves the ceiling as a fraction of its
input total, so a second pass yields P*(P*T) instead of P*T and distorts
UsagePercent (read by the memory reclaimer in pkg/model/watchdog.go).

Remove the redundant second application so the budget is applied exactly
once, against the raw physical totals, upstream in GetGPUAggregateInfo.

LocalAI [bot]andEttore Di Giacinto 97175f4b5a feat(model): debounce model loads after a failure to stop retry-storms (#10728)
A client that keeps polling a model whose load fails (e.g. a backend that
crashes deterministically on init) triggered a fresh backend start on
every request: request -> load -> crash in ~10s -> 500, repeat on the
next poll. Each attempt could leak GPU/CUDA state, and under
LOCALAI_SINGLE_ACTIVE_BACKEND it kept stealing the active slot from
healthy models. The existing loading-coalesce map only dedups
*concurrent* loads, so sequential polls were never covered.

Track load failures per modelID in ModelLoader. After a load fails,
refuse fresh load triggers for that model until a cooldown elapses,
returning a typed ModelLoadCooldownError that the HTTP layer maps to 503
with a Retry-After header. The cooldown grows exponentially per
consecutive failure (base, doubling, capped at 5m) and resets on a
successful load. The coalesced follower-retry of an in-flight burst
bypasses the gate, so a genuinely concurrent burst still gets its one
retry -- only new, independent triggers are refused, matching the
report's "refuse new load-triggers" wording.

Configurable via --model-load-failure-cooldown /
LOCALAI_MODEL_LOAD_FAILURE_COOLDOWN (default 10s, 0 disables), plumbed
through ApplicationConfig and applied unconditionally at startup.

Closes #10719

LocalAI [bot]andEttore Di Giacinto 461ae84732 fix(startup): scope generated-content and upload dirs to the current user (#10698)
The `--generated-content-path` and `--upload-path` defaults were the fixed
shared locations `/tmp/generated/content` and `/tmp/localai/upload`. On any
multi-user host these collide across accounts: macOS routes `/tmp` to the
shared `/private/tmp` for every user, so whichever account starts LocalAI
first creates the parent with 0750 perms and every other account then fails
startup with:

    unable to create ImageDir: "mkdir /tmp/generated/content: permission denied"
    unable to create UploadDir: "mkdir /tmp/localai/upload: permission denied"

The same happens on Linux once a stale root-owned `/tmp/generated` (e.g. from
a prior `sudo` run) is left behind. This bites the desktop launcher and any
app embedding the raw binary (Wingman, nib-desktop), which start `local-ai
run` with no path flags.

Default both paths under the OS temp dir (`os.TempDir()`, honoring `$TMPDIR`;
already per-user on macOS) namespaced by the current UID
(`TMPDIR/localai-<uid>/...`), so accounts never collide while the paths stay
ephemeral. Wired via new kong vars in main.go so every consumer of the raw
binary inherits the fix. All content subdirs (audio, images) derive from
`GeneratedContentDir`, so they are fixed transitively.

As defense in depth, the launcher also anchors these two paths under its own
per-user data directory (mirroring the #10610 fix for data/config), extracted
into a testable `BuildRunArgs`.

LocalAI [bot]andEttore Di Giacinto f3d829e2ef feat(distributed): add LOCALAI_DISTRIBUTED_SHARED_MODELS to skip staging on shared volumes (#10556) (#10566)
In distributed mode, even when the frontend and workers share the same
models directory via a shared volume mount, starting a model on a worker
re-staged (re-downloaded) it: stageModelFiles always uploads model files
into a tracking-key-namespaced subdir on the worker, and the staging probe
only checks that staged location, so a file already present on the shared
volume at the canonical path was never reused.

Add a config switch LOCALAI_DISTRIBUTED_SHARED_MODELS (default false). When
enabled, the operator asserts that all nodes mount the SAME models directory
at the SAME path, so staging is unnecessary: the frontend's absolute model
paths are already valid on the worker. In that mode stageModelFiles returns
the cloned opts unchanged without uploading, leaving the path fields pointing
at their canonical absolute paths so the worker loads them directly from the
shared volume.

The value is plumbed from DistributedConfig through SmartRouterOptions into
the SmartRouter. Docs and docker-compose.distributed.yaml updated.

When LOCALAI_PREFER_DEV_BACKENDS is set, install the -development image as the

Threads PreferDevelopmentBackends through SystemState so InstallBackend can see
it, and reuses the same development-URI convention as the existing failure-path
fallback (released tag -> branch tag + dev suffix). The unexported developmentURI
helper is covered by a Ginkgo spec.

Richard PalethorpeandEttore Di Giacinto e1994579f8 fix(pii): load default detectors at startup + add LOCALAI_PII_DEFAULT_DETECTORS (#10474)
pii_default_detectors was applied to the live config only by a live
POST /api/settings (ApplyRuntimeSettings) — neither the startup loader nor
the config file watcher read it back. So after a restart the persisted
default detectors were dropped, and the cloud-proxy MITM listener (which
resolves each intercept host's detectors once at start via ResolvePIIPolicy)
came up with an empty set and forwarded intercepted traffic unredacted, even
though the MITM model had pii.enabled:true and the defaults were on disk.
Request-side default redaction broke the same way.

- startup.go: loadRuntimeSettingsFromFile now applies pii_default_detectors,
  before startMITMIfConfigured, with env > file precedence.
- config_file_watcher.go: apply pii_default_detectors on live file edits,
  matching the existing env-guard pattern used for the other fields.
- settings endpoint: rebuild the MITM listener when pii_default_detectors
  changes (its per-host detector map is frozen at listener start), not only
  on a mitm_listen change — so toggling a default detector takes effect on
  cloud-proxy traffic immediately.
- new LOCALAI_PII_DEFAULT_DETECTORS env var / CLI flag (WithPIIDefaultDetectors)
  so the default detector set can be pinned at boot for immutable deployments.

Leoy b50b1fe418 feat(watchdog): add size-aware LRU eviction mode (#9527)
* feat(watchdog): add size-aware LRU eviction mode

When the model count hits the LRU limit or the memory reclaimer fires,
evict the largest model by on-disk file size first rather than the
least-recently-used one.  For GGUF models the file size is a reliable
proxy for GPU/RAM footprint, so evicting the largest candidate maximises
freed memory per eviction round while keeping small utility models
(embeddings, classifiers, rerankers) resident.

Changes:
- `pkg/model/watchdog.go`: add `sizeAwareEviction` flag and
  `modelSizes map[string]int64` to `WatchDog`; sort candidates by
  `sizeBytes` desc (LRU time as tiebreaker) when the flag is set;
  add `RegisterModelSize`, `SetSizeAwareEviction`, `GetSizeAwareEviction`
- `pkg/model/watchdog_options.go`: add `WithSizeAwareEviction` option
- `pkg/model/initializers.go`: stat model file after load and call
  `RegisterModelSize` so size data is available before the first eviction
- `core/config/application_config.go`, `runtime_settings.go`: add
  `SizeAwareEviction` field and `WithSizeAwareEviction` app option;
  expose via `ToRuntimeSettings` / `ApplyRuntimeSettings` for the
  `POST /api/settings` live-reload path
- `core/cli/run.go`: add `--size-aware-eviction` flag /
  `LOCALAI_SIZE_AWARE_EVICTION` env var
- `core/application/startup.go`, `watchdog.go`: wire the new option
  through to `NewWatchDog`
- `pkg/model/watchdog_test.go`: 5 new specs — option enable, dynamic
  toggle, largest-first ordering, equal-size LRU tiebreaker, no-size
  fallback to LRU, and size-map cleanup on eviction

* refactor(watchdog): use vram estimation scaffolding for model size

Replace the brittle os.Stat(modelFile) approach with a proper call to
pkg/vram, which handles multi-file models (DownloadFiles, MMProj) and
all weight file types, not just single GGUF files.

- Add estimateModelSizeBytes() in core/backend/options.go that collects
  all weight file URIs from the model config, resolves them to file://
  URIs, and calls vram.Estimate() with the shared DefaultCachedSizeResolver
  (15-min TTL cache avoids redundant stat calls on repeated loads)
- Thread the result through via a new WithModelSizeBytes() loader option
- In initializers.go, consume the pre-computed size instead of calling
  os.Stat; if no size was supplied (e.g. for external/router-dispatched
  models) the registration is simply skipped

* refactor(watchdog): use EstimateModel with HF fallback for size estimation

Switch estimateModelSizeBytes from calling vram.Estimate directly to the
unified vram.EstimateModel entry point, which adds automatic fallbacks:
file-based GGUF metadata → HF API → size string.

Also extract the HuggingFace repo ID from model URIs (huggingface://,
hf://, https://huggingface.co/ and org/model short-form) and pass it
as ModelEstimateInput.HFRepo, so models not yet downloaded locally can
still get a size estimate via the HF API.

Addresses @mudler's review feedback: "better to rely on EstimateModel
and pass by the HF URL of the model extracted from the URI".

* feat(webui): add Size-Aware Eviction toggle to settings page

The size-aware eviction setting was wired through the CLI flag and the

Add a Size-Aware Eviction toggle to the Watchdog section, next to the
existing Force Eviction When Busy / LRU eviction handles. The settings
page loads and saves the whole RuntimeSettings object, so the new
size_aware_eviction key is picked up with no extra plumbing.

Addresses @mudler's review feedback: the application config setting
should land on the same UI settings page as the other handles.

LocalAI [bot]andEttore Di Giacinto b203b32e57 feat(realtime): make WebRTC ICE candidates configurable (#10231)
The /v1/realtime WebRTC handler created the peer connection with a bare
webrtc.Configuration and no SettingEngine, so pion gathered a host ICE
candidate for every local interface. Under Docker host networking that
includes bridge addresses (docker0/veth, 172.x) a remote browser cannot
route to; the call establishes on a good pair and then drops once ICE
consent freshness checks fail on the unreachable candidates.

Add two opt-in knobs, applied via a pion SettingEngine:
- LOCALAI_WEBRTC_NAT_1TO1_IPS: advertise these IPs as the host candidates
  (e.g. the host LAN IP)
- LOCALAI_WEBRTC_ICE_INTERFACES: restrict ICE gathering to these interfaces

Defaults are unchanged (empty => current all-interface behavior).

Ching 8344d1c865 feat(cli): add interactive chat mode (#10226)
Add an opt-in `local-ai chat` command for testing chat models directly from the terminal without manually sending curl requests.

The command connects to a running LocalAI server, lists available models through the existing OpenAI-compatible API, streams chat completions, and supports interactive commands such as `/models`, `/model`, `/clear`, and `/exit`.

Keep `local-ai run` focused on the server lifecycle so the web UI, API clients, and multiple chat terminals can coexist against the same server.

Document the new command and terminal workflow in the README and CLI docs.

Tests:
- go test -count=1 ./core/cli/chat
- go test -count=1 ./core/cli

Richard Palethorpe 73385713ca feat(distributed): enforce registration token for worker file transfer (#10183)
The worker HTTP file-transfer server is authenticated by the registration
token via checkBearerToken, which fails open on an empty token: every
/v1/files, /v1/files-list and /v1/backend-logs request is then served
unauthenticated, granting read/write to the worker's models/staging/data
directories. The fail-open was also silent (the only auth log sat on the
unreachable reject branch), and the worker process never runs
DistributedConfig.Validate(), so the existing frontend warning did not
cover the component that exposes the server.

Mirror the NatsRequireAuth pattern: keep anonymous as the default but make
it loud and opt-in enforceable.

- Log a prominent warning when the file-transfer server starts tokenless.
- Add LOCALAI_REGISTRATION_REQUIRE_AUTH: DistributedConfig.Validate() errors
  on an empty token (frontend) and the worker refuses to start (fail-fast,
  before registration), so production can fail closed. Also satisfies the
  F-003 suggestion to fail Validate() on distributed + empty token.
- Add LOCALAI_DISTRIBUTED_REQUIRE_AUTH umbrella switch implying both
  RegistrationRequireAuth and NatsRequireAuth — one production knob locking
  down the registration/file-transfer layer and the NATS bus together; the
  granular flags remain available as single-layer overrides. Wired into the
  frontend, supervisor worker, and agent worker (vLLM worker has neither a
  NATS connection nor a file-transfer server, so it is left untouched).
- Document in distributed-mode.md (warning callout + flag tables).

* fix(distributed): correct NATS JWT scoping and harden client auth

The JWT-auth path added in 46467cc7 had several gaps that fail silently
under LOCALAI_NATS_REQUIRE_AUTH:

- Agent-worker minted JWTs did not allow the subjects the agent worker
  actually subscribes to (jobs.mcp-ci.new and nodes.<id>.backend.stop),
  so MCP-CI jobs and backend-stop session cleanup were silently dropped.
  Scope the agent permission set to those subjects.
- NATS subscription permission violations were swallowed (Subscribe
  returned a live-but-dead subscription). Confirm subscriptions with a
  server round-trip so a denial surfaces synchronously, and log async
  permission errors.
- The backend worker connected anonymously when given a JWT without its
  paired seed; reject the unpaired credential instead.
- The documented service-user permissions in nats-auth-setup.sh omitted
  prefixcache.>, which the frontend publishes and subscribes; add it.

Also: add a credential-provider hook to the messaging client (consumed by
the follow-up credential-lifecycle change), drop the always-nil error from
NatsMessagingOptions, run go mod tidy (jwt/v2 and nkeys are now direct),
and gofmt the feature's files.

Tests: an agent-JWT e2e spec that connects to the enforcing NATS server
and exercises every subscription the agent worker makes, plus permission
allow-list coverage unit tests.

* feat(distributed): acquire and auto-refresh worker NATS credentials

Workers fetched NATS credentials once at startup, which broke two cases
under JWT auth: a worker that registered while still pending admin
approval never received a minted JWT (it connected unauthenticated and
gave up), and a long-running worker's 24h JWT expired with no way to renew
it.

Introduce workerregistry.NATSCredentialManager, built on idempotent
re-registration (the frontend preserves the node row and mints a fresh JWT
each call):

- Acquire re-registers through admin approval until the node is approved
  and credentials are minted (or returns the first success when auth is
  not required, preserving anonymous-NATS behavior).
- RefreshLoop re-registers before the JWT expires (~75% of its lifetime),
  updating the credentials served to the connection.
- Both are bounded (default 100 attempts / consecutive failures) and
  return an error on exhaustion, so an unapprovable or unrenewable worker
  exits non-zero and surfaces the problem instead of hanging or drifting
  toward an expired credential.

The messaging client gains WithUserJWTProvider, fetching credentials on
each (re)connect so the connection transparently adopts a refreshed JWT
when the server expires the old one. RegisterFull exposes the approval
status and full response; Register delegates to it.

Both the backend worker and the agent worker are wired to this: explicit
env credentials are used as-is, minted credentials are acquired-with-wait
and refreshed, and a permanent refresh failure shuts the worker down so it
restarts and re-acquires.

Tests cover Acquire (wait-through-pending, bounded give-up, context
cancel), RefreshLoop (refresh-before-expiry, bounded failure, no-expiry
exit) and jwtExpiry decoding. Docs updated in distributed-mode.md.

  Previously evictOldestLocked cleared a victim's value but never
  removed the now value-less node or its childless ancestors, so
  internal nodes accumulated under sustained churn at the cap. The
  MaxEntries path now prunes the victim and its empty ancestors.
- DRY: pruneWalk replaces the duplicated logic in the former
  pruneLocked and Remove's inner closure.
- Switch Tree.mu to sync.RWMutex; LongestMatch, Weight and Len take
  the read lock (RLock) while Insert, Evict and Remove keep the write
  lock. Confirmed race-clean under go test -race.
- Document the strict greater-than TTL boundary on Options.TTL and
  expired: age exactly equal to TTL is still live.
- Guard Insert against an empty key (no-op): the root never holds a
  value.

Address code-quality review findings in the prefixcache package.

Correctness: ExtractChain now chunks from absolute offset 0 with fixed
[0,W),[W,2W),... boundaries and caps the chain to the FIRST MaxDepth
head blocks. The previous tail-keeping logic shifted the byte offset by a
non-window amount once a conversation grew past MaxDepth*WindowBytes,
changing every hash each turn and silently breaking cross-turn
longest-prefix matching. The reusable KV/prefix cache lives at the head
of the prompt, so anchoring at offset 0 makes the chain a true
prefix-chain: P and P+suffix share their full leading overlap. Add a
regression spec proving cross-turn stability past the cap.

Performance: Index.Decide precomputes each candidate's Weight once
(decorate-sort-undecorate) instead of calling the O(tree size) Weight
inside the O(n log n) sort comparator. Behavior is unchanged.

Lint: encode prev with binary.LittleEndian.PutUint64 instead of a manual
byte loop, clearing the modernize rangeint finding.

Also add a concurrent Decide/Observe/Invalidate spec to exercise Index's
documented concurrency safety under go test -race.

(distributedhdr.PrefixChain), resolves the per-model policy/thresholds over
the global config, loads candidate replica in-flight via a new registry read
LoadedReplicaStats (deduped to one entry per node using the MIN in-flight
across that node's replicas), asks the provider to Decide, and runs
prefixcache.Select. The chosen node is passed as the RoutePreference to
FindAndLockNodeWithModel on all three pick paths (cache hit, locked re-pick,
cold scheduleAndLoad), and the served node is recorded via Observe only when
the resolved policy is prefix_cache so round-robin models never pollute the

* feat(nodes): autoscale on prefix-cache forced-disturb pressure

Wire the rolling forced-disturb counter into the SmartRouter and the
ReplicaReconciler.

Router: in buildPreference, after Decide + Select, record a forced-disturb
when a usable hot prefix match existed (d.HotNodeID != "" and
d.MatchRatio >= cfg.MinPrefixMatch) but Select chose a different node (or
nothing) because the load guard ruled the warm node out. This is the
scale-worthy signal: the cache-warm replica is saturated. It deliberately
does not fire for all-unique workloads (no hot match), avoiding
false-positive scale-ups. Pressure is optional on SmartRouterOptions; nil
keeps the path a no-op.

Reconciler: read the same Pressure instance in reconcileModel as an extra
scale-up reason, reusing the existing MaxReplicas + ClusterCapacityForModel
guards and the UnsatisfiableUntil cooldown that gates the whole method.
Pressure never overrides MaxReplicas and never force-evicts; a no-capacity
model does not spin. Window and threshold come from prefixcache.Config
(PressureWindow default 1m, PressureScaleThreshold default 1) and are
configurable via ReplicaReconcilerOptions.

* fix(prefixcache): bound Pressure slice in Record; drop dead reconciler pressureWindow

Record now prunes entries older than the rolling window (the same prune
Count does), via a shared pruneLocked helper, so a model that takes
forced-disturb records but is never Counted (e.g. one with zero loaded
replicas the reconciler skips) no longer grows its backing slice
unbounded.

Also removes the dead pressureWindow struct field and the
ReplicaReconcilerOptions.PressureWindow option from the reconciler: they
were stored but never read (the window lives inside the *prefixcache.Pressure
instance). The scale block now reads pressure.Count once into a local.

PrefixProvider/PrefixConfig/Pressure into the SmartRouter and
Pressure/PressureThreshold into the ReplicaReconciler, and runs a
background eviction ticker (every TTL/2) bound to the app context.

Enabled by default; --distributed-prefix-cache=false (LOCALAI_DISTRIBUTED_PREFIX_CACHE)

xxhash seed 0 is stateless, so Reset()+Write produces the byte-identical

ExtractChain output for the existing test inputs before and after the

* fix(prefixcache): drop hot match when matched node is not a candidate; weigh cold candidates in one walk

Index.Decide called radixtree.LongestMatch over the whole tree, so the
deepest match could be a node that is offline, unloaded, or simply not in
the passed candidate set. Honoring that as HotNodeID produced a false
forced-disturb signal upstream (buildPreference records pressure when
chosen != HotNodeID), making it look like a warm replica was load
saturated when it was actually absent.

Build the candidate set once and only set HotNodeID/MatchRatio when the
matched node is an actual candidate; otherwise fall back to cold
placement. A future refinement could ask the tree for the longest match
restricted to the candidate nodes (shallower-but-valid) instead of
dropping it.

Also replace the per-candidate tree.Weight call in the cold-order sort
with a single tree.WeightsFor walk, turning O(K*N) under the read lock
into O(N + K).

* fix(autoscale): add Pressure.Reset to consume forced-disturb signal

Pressure.Count is non-draining (it prunes only by age), so a single burst
of forced-disturbs stays within the rolling window for the whole window and
keeps Count >= threshold on every reconciler tick. The reconciler will use
Reset to clear a model's events after acting on the signal so a fresh
scale-up requires fresh forced-disturbs to accumulate, rather than one burst
driving the model toward MaxReplicas.

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

* fix(autoscale): at most one scale-up per reconcile tick, consume pressure

Two autoscale bugs:

1. Over-scaling: the pressure scale-up block read Pressure.Count but never
   consumed it. With a non-draining counter a single forced-disturb burst
   kept Count >= threshold across the whole window, firing scaleUp on every
   tick and pushing the model toward MaxReplicas off one transient burst.
   After a successful pressure-triggered scale-up the reconciler now calls
   Pressure.Reset to consume the signal.

2. Double scale-up in one tick: the all-replicas-busy block and the pressure
   block could both fire in the same reconcileModel pass, each calling
   scaleUp(+1) against the same `current` read once at the top, so a model
   that was both busy and over threshold scaled +2 and could overshoot
   MaxReplicas by one. A scaledUp flag now enforces at most one scaleUp(+1)
   per tick: the pressure block is skipped if the busy block already scaled,
   and scale-down is skipped in any tick that scaled up.

MinReplicas enforcement, UnsatisfiableUntil backoff, and capacity guards are
unchanged.

* feat(nodes): replica-removed chokepoint hook for prefix-cache invalidation

Add SetReplicaRemovedHook to NodeRegistry and fire it from both
RemoveNodeModel and RemoveAllNodeModelReplicas after a successful
delete. This is the single chokepoint every replica-removal path funnels
through (router eviction, reconciler scale-down, probe reaper,
health-monitor node-down reap, RemoteUnloaderAdapter), so the
prefix-cache index can be invalidated by construction rather than wiring
each call site individually.

The hook is stored in an atomic.Pointer so the startup wiring (setter)
and the request/reconcile-time fire are race-free; it is nil-safe when
unset. GORM Delete reports no error for a no-op delete, so the hook also
fires when nothing was removed; the consumer's Invalidate(model, node)
is idempotent so this is harmless.

Make the four prefix-cache request fields pointers so omitted is
distinguishable from explicit zero, and merge PATCH-style in

* fix(prefixcache): make Invalidate a no-op for uncached models and skip empty broadcasts

A registry chokepoint fires Sync.Invalidate(model, nodeID) for every replica

prefix cache. Index.Invalidate previously called tree(model), which lazily
created and permanently retained an empty radix tree for any model that ever
lost a replica, growing the trees map without bound. Sync.Invalidate also
published a NATS PrefixCacheInvalidateEvent on every call, amplifying no-op
removals across the cluster.

Index.Invalidate now looks the tree up read-only via existingTree and returns
without allocating when none exists. The Provider interface is unchanged;
Sync gates the broadcast through an optional invalidateExisting(bool) capability
type-asserted from the wrapped Index, falling back to the prior always-broadcast
behavior for other Provider implementations.

the hot-match check on weights membership. Also skip the sort when there is at
most one candidate, since the input order is already the cold order. Behavior

* fix(nodes): fire replica-removed hook on bulk node_models deletes; trim LoadedReplicaStats columns

Bulk node-scoped node_models deletes (Register re-register cleanup,
MarkOffline, MarkDraining, Deregister) removed rows directly without
firing the replica-removed hook, so the prefix-cache index kept
pointing at nodes whose models were gone. Capture the DISTINCT model
names before each bulk delete and fire fireReplicaRemoved once per
model after a successful delete, restoring the single-chokepoint
invariant for all removal paths. The pre-query is skipped when no hook
is set so the no-hook path stays cheap.

Also narrow LoadedReplicaStats to SELECT only node_id and in_flight
(the only fields the router consumer reads), dropping the JOIN-side
available_vram fetch and unused columns while keeping the
[]ReplicaCandidate return type unchanged.

* fix(reconciler): consume autoscale signals only on a real scale-up

scaleUp was fire-and-forget (void) yet its callers unconditionally
consumed the pressure signal (Pressure.Reset) and the MinReplicas
hysteresis (ClearUnsatisfiable) right after calling it. If scaleUp
added nothing (ScheduleAndLoadModel errored, or no node could be
loaded) the saturated warm replica got no new replica AND its
accumulated forced-disturb history was wiped, forcing the signal to
re-accumulate over a full PressureWindow before the next attempt.

Make scaleUp return whether at least one replica was actually
scheduled, and gate the side effects on it:

- pressure block (2b): set scaledUp and call Pressure.Reset only on
  success; on failure preserve the signal so the next tick retries off
  the same accumulated pressure.
- busy-burst block (2): set scaledUp from the return value so a failed
  attempt does not suppress the pressure path or scale-down.
- MinReplicas block: call ClearUnsatisfiable only on success so a
  failed attempt does not reset the unsatisfiable counter.

All existing invariants (MaxReplicas, capacity gating,
UnsatisfiableUntil cooldown, at-most-one-scale-up-per-tick) are
preserved.

* refactor(nodes): drop router's redundant prefix-cache Invalidate calls

The NodeRegistry removal chokepoint (RemoveNodeModel /
RemoveAllNodeModelReplicas) now fires SetReplicaRemovedHook, which
invalidates the prefix-cache index. The router was also calling
prefixProvider.Invalidate explicitly right after each registry removal
on the two stale-replica health-probe fall-throughs in Route and in
UnloadModel, so every router-side eviction invalidated twice (double
tree-prune + double NATS broadcast).

Remove the three redundant explicit Invalidate calls and their empty
nil-guards. Each removed call sat immediately after a registry removal
that fires the hook, so invalidation is preserved via the chokepoint.
Decide/Observe usage is untouched.

Re-point the unit test (fake registry fires no hook) to assert the
removal chokepoint is exercised on unload instead of the router's
direct invalidation.

* fix(nodes): make capture+delete atomic in bulk node_models removal paths

MarkOffline, MarkDraining, and the Register re-register cleanup ran the
nodeModelNames SELECT and the bulk node_models DELETE as two separate
statements on r.db with no transaction. A SetNodeModel landing between
the two was deleted but its replica-removed hook never fired, leaving
the prefix-cache index pointing at a removed replica until TTL or
candidacy self-heal.

Wrap the capture and the delete in a single db.Transaction in each path
(mirroring how Deregister already does it). The captured model names are
collected into a slice declared outside the closure; the
replica-removed hook fires for each only after the transaction commits,
so a rollback never invalidates the index for a removal that did not
persist. The set of fired hooks now equals exactly the set of
node_models rows actually deleted, with no interleaving gap.

The status flip in MarkOffline/MarkDraining (setStatus) is a separate,
pre-existing operation and routing already filters non-healthy nodes, so
it stays outside the transaction; return contracts are unchanged.
Deregister was already correct and is untouched. The cheap-path skip
(no hook -> skip the SELECT) is preserved.

Adds a spec asserting MarkOffline fires hooks for exactly the rows it
deletes and leaves no node_models row behind (consistent snapshot).

* fix(radixtree): match shared prefixes by valuing every node on insert

Insert recorded the value (node id) only on the final node of the key
chain, leaving every intermediate prefix node valueless. LongestMatch
returns the deepest node that hasValue, so two chains that share a
leading block but diverge in the tail never matched: only exact-repeat
queries hit. That broke the prefix-cache routing core use cases (shared
system prompt, multi-turn extension, volatile tail), all of which rely
on prefix matching rather than exact-repeat.

Set value/hasValue/lastSeen at every node along the chain so each
prefix-block node remembers the node id that served that prefix
(SGLang/vLLM-style). The deepest match wins, and the last writer owns a
shared prefix node (a recency heuristic: the most recent chain through a
block is the one most likely still warm). size now counts valued nodes,
which is the intended meaning.

Updated radixtree tests to the new semantics: deepest-prefix test uses
non-overlapping chains, a new test asserts last-writer-owns-shared-node,
Evict/Remove/MaxEntries expectations recomputed for per-prefix-node
counting, and a shared-prefix LongestMatch red test added. Added a
prefixcache Decide test proving a prefix-only query routes to the warm
node. No prefixcache .go logic changed.

* test(distributed): lock in prefix-cache routing behavior end to end

Add a DB-backed e2e spec that drives SmartRouter against a real
NodeRegistry (Postgres testcontainer) and the real prefixcache.Index
radix-tree provider, using a fake gRPC backend factory so no real
inference runs. Covers the five behaviors validated by hand:

1. Cold miss + observe: an unseen prefix chain cold-places and is recorded.
2. Hot-match affinity: the same chain returns to its warm node X.
3. Shared-prefix match: a divergent chain sharing X's leading prefix
   still routes to X (the radix-tree regression we fixed).
4. Negative control: an unrelated chain is a cold miss, not a false
   hot match on X.
5. Failover + invalidation: removing X's replica fires the registry
   chokepoint hook to invalidate the prefix entry, and the chain fails
   over to surviving node Y and re-homes there.

Replaces the need for manual docker-compose re-runs.

* refactor(prefixcache): make prefix-cache affinity replica-granular

Track prefix-cache affinity per loaded replica (a backend process with its
own KV cache) instead of per node, so multiple replicas of the same model on
one node each keep distinct affinity and a hot prefix routes back to the exact
replica that served it.

- radixtree: add RemoveFunc(pred) and reimplement Remove on top of it.
- prefixcache: introduce ReplicaKey{NodeID, Replica}; Index/Candidate/
  PrefixDecision/Select/Provider now key on ReplicaKey. Add InvalidateNode to
  drop every replica of a node; Invalidate drops one replica. Select returns
  (ReplicaKey, bool) and gains a deterministic least-in-flight eligible
  fallback (tiebreak NodeID then Replica).
- messaging: carry Replica on PrefixCacheObserveEvent and
  PrefixCacheInvalidateEvent (Replica < 0 means all replicas of the node).
- Sync delegates + broadcasts with replica; InvalidateNode broadcasts
  Replica=-1; ApplyInvalidate routes negative replica to InvalidateNode.

This is part 1 of 2; the registry/router/wiring consumers are updated
separately.

* feat(distributed): make prefix-cache routing replica-granular

Wire the SmartRouter, NodeRegistry, and distributed startup to the
replica-keyed prefixcache API. Affinity is now tracked per replica
(each replica is a separate process with its own KV cache), so a prefix
served by (node,0) no longer leaks onto the same-node sibling (node,1).

- RoutePreference gains PreferredReplica; FindAndLockNodeWithModel locks
  the EXACT (node_id, replica_index) row, falling through to the default
  ORDER BY when that replica is not loaded.
- SetReplicaRemovedHook now carries replicaIndex; RemoveNodeModel fires
  the specific replica, RemoveAllNodeModelReplicas and the four bulk
  node-scoped deletes fire replica<0 (all replicas of the node).
- buildPreference builds one Candidate per loaded replica and locks the
  exact replica the policy chose; observePrefix records the served
  ReplicaKey at every call site.
- distributed.go routes the hook to InvalidateNode (replica<0) or
  Invalidate(key).
- Tests updated to the replica-keyed API plus new coverage: a hot prefix
  on (node,0) prefers replica 0 over the same-node sibling (router unit +
  e2e), and FindAndLock locks the exact preferred replica.

* fix(distributed): derive prefix chain from messages for tokenizer-template models

Prefix-cache-aware routing built its prompt-prefix chain from the rendered
prompt string `s` in ModelInference. For models with
TemplateConfig.UseTokenizerTemplate the frontend never renders a prompt - the
backend tokenizes the structured messages itself - so `s` is empty, the chain
is empty, and routing silently falls back to round-robin. That covers the bulk
of modern chat models (qwen3, llama3, ...), so the feature effectively never
engaged for them.

Fall back to messagesPrefixSource(messages): a deterministic, prefix-stable
head-first serialization of the conversation (role + content per turn). Two
requests sharing a leading system prompt and early turns share a leading byte
prefix, which ExtractChain maps to a shared chain prefix - landing both on the
same cache-warm replica. The rendered `s` is still preferred when present
(higher fidelity for non-template models).

Found via the multi-replica-per-node e2e: zero "prefix-cache routing decision"
logs despite per-request Route calls, traced to the empty-chain guard.

Richard Palethorpe fbcd886a47 fix(application): stop backend processes synchronously on shutdown (#10058)
application.New wires a fire-and-forget goroutine that runs
StopAllGRPC + distributed.Shutdown when the app context is cancelled.
Callers (tests, CLI signal handler) cancel the context and then exit
immediately, so the test binary / process can terminate before that
goroutine kills the spawned backend children. go-processmanager sets no
Pdeathsig, so the orphans are reparented to init and survive — leaving
dozens of stray mock-backend processes after an e2e run.

Add Application.Shutdown(), which runs the same cleanup synchronously on
the caller's stack and is idempotent via sync.Once. The context-cancel
goroutine, the CLI signal handler, and the test suites all call it, so
cleanup is deterministic and the duplicated teardown logic collapses to
one place. The async goroutine remains as a safety net for callers that
forget; sync.Once dedupes the double call.

Wire e2e_suite_test and the two mock-backend Contexts in app_test to
call Shutdown in their AfterSuite/AfterEach.

Introduce pkg/distributedhdr, a leaf package carrying a per-request
*atomic.Value holder for the picked worker node ID from the
SmartRouter (core/services/nodes) up to the HTTP response writer
wrapper (core/http/middleware). Avoids the import cycle that a shared

reveals internal topology and is opt-in).

The middleware creates a per-request *atomic.Value holder, attaches it
to c.Request().Context() via distributedhdr.WithHolder, and wraps
c.Response().Writer with a custom http.ResponseWriter that sets the
X-LocalAI-Node header on first Write / WriteHeader / Flush by reading
the holder. Implements http.Flusher, http.Hijacker, Unwrap so it
composes cleanly with Echo and http.NewResponseController.

request.go propagates the holder onto derived contexts via

- OpenAI chat/completion/embeddings + audio transcriptions/speech + image generations/inpainting
- Anthropic /v1/messages
- Ollama /api/chat, /api/generate, /api/embed, /api/embeddings
- Jina /v1/rerank
- LocalAI /v1/vad

X-LocalAI-Node response header before delegating to the underlying
writer. Per-request scope means no race under concurrent multi-replica
routing.

* fix(distributed): thread request context through backend Load + cover ctx propagation

Five non-OpenAI backend helpers were silently using app.Context instead
of the request context for the gRPC backend call: transcription, TTS,
image generation, rerank, VAD. Effect: distributedhdr.Stamp in the
router callback was a silent no-op for these paths, AND client
cancellation didn't propagate to in-flight inference.

Thread c.Request().Context() (or the equivalent input.Context after
the request middleware has installed the correlation-ID derived
context) through each helper and into ModelOptions via
model.WithContext(ctx). ImageGeneration's signature gains a leading
ctx parameter; in-tree callers (openai image, openai inpainting,
openai inpainting_test) are updated to match.

ModelEmbedding gains a leading ctx parameter for the same reason; the
openai and ollama embedding handlers pass the request context through.

chat_stream_workers.go defers the initial role=assistant chunk
emission until the first token callback so the wrapper's lazy
X-LocalAI-Node lookup against the loader runs AFTER ml.Load has
stamped the per-modelID node ID; semantically identical for clients
(role still arrives before any text).

Regression test core/backend/ctx_propagation_test.go pins ctx
propagation for all five helpers.

Docs updated to enumerate the full endpoint coverage of the
--expose-node-header flag.

* feat(distributed): treat NATS install timeout as in-progress, not failure

When a worker times out replying to backend.install but the install is

timeout so the reconciler does not immediately re-fire another install
while the worker is still pulling the image. The pending_backend_ops
row stays in place for the next reconciler pass to confirm via
backend.list.

InstallBackend wraps the result in galleryop.ErrWorkerStillInstalling
so callers can branch (galleryop renders yellow in-progress instead of
red error). UpgradeBackend uses the same wrap.

Adds RemoteUnloaderAdapter.InstallTimeout() so the manager can push
NextRetryAt by the configured timeout without reaching into a private
field, and NodeRegistry.RecordPendingBackendOpInFlight as the soft
cousin of RecordPendingBackendOpFailure.

trip the reconciler's maxPendingBackendOpAttempts cap and dead-letter
the queue row while the worker was still legitimately working.

download callback. Each tick becomes a BackendInstallProgressEvent on
nodes.<nodeID>.backend.install.<opID>.progress; the publisher always
emits a final event on Flush so the UI sees the terminal percentage.

Old masters that do not set OpID continue to run silent installs: no

the install loop.

* feat(distributed): RemoteUnloaderAdapter subscribes to install progress

InstallBackend gains opID + onProgress parameters. When both are set,
the adapter subscribes to nodes.<nodeID>.backend.install.<opID>.progress
BEFORE publishing the install request, decodes each message into the
caller's onProgress callback in a goroutine (so a slow callback never
stalls the NATS reader thread), and unsubscribes after RequestJSON
returns.

When onProgress is nil OR opID is empty (the reconciler retry path),
subscription is skipped entirely - silent installs cost nothing extra.

Subscribe failure is logged at Warn and the install proceeds without
progress streaming; the NATS round-trip still owns terminal status.

* feat(distributed): forward backend install progress into galleryop OpStatus

DistributedBackendManager.InstallBackend now passes the gallery op ID
and a progress bridge into the adapter call. Each
BackendInstallProgressEvent from the worker becomes a
galleryop.ProgressCallback tick - which the existing backendHandler
already turns into OpStatus.UpdateStatus, so the admin UI/SSE polling
sees per-byte progress for distributed installs without any UI-side
change.

UpgradeBackend is intentionally left silent for now: its wire request
(BackendUpgradeRequest) does not carry OpID, and rolling-update
fallback is the rarer path. Will be picked up in a follow-up if the
worker upgrade path also gets a progress channel.

DownloadedFileSize / TotalFileSize fields so the legacy single-bar
OperationsBar view keeps working unchanged alongside the new per-node

* feat(distributed): write per-node OpStatus entries during install fan-out

DistributedBackendManager now accepts a nodeProgressSink and feeds it
two streams:

1. enqueueAndDrainBackendOp emits a per-node terminal entry on each
   status it appends to BackendOpResult (queued, success, error,
   running_on_worker). The opID is threaded through the function so
   the sink gets the right gallery op identity.

2. The install apply closure fans each BackendInstallProgressEvent
   into the sink as a downloading entry, alongside the legacy
   progressCb path so the aggregate single-bar view stays correct.

Production wiring passes the GalleryService (which implements
UpdateNodeProgress via Task 2) as the sink. Single-node tests pass
nil. DeleteBackend and UpgradeBackend pass an empty opID so the
sink path no-ops for ops that aren't gallery-tracked the same way

* feat(operations): expose per-node breakdown on /api/operations

When an operation's OpStatus has Nodes entries (populated by the
Phase 4 progress sink wiring), surface them as a "nodes" array on the
/api/operations response, sorted by node_name for stable rendering.

Backward compatible: legacy clients ignore the field; ops without any
node entries (single-node mode, model installs) omit the array entirely
thanks to the empty-slice guard.

* feat(ui): per-node breakdown in OperationsBar

When an install op fans out to more than one worker, the operations
bar now shows a "N nodes" chevron that expands into a per-node list.
Each row carries the node's status (color-coded pill), the current
file being downloaded, byte counts, percentage, and a thin per-node
progress bar. Yellow "Worker busy" pill marks running_on_worker
status with a tooltip explaining the NATS round-trip timed out but
the worker is still installing in the background.

Backward compatible: ops without a nodes field (legacy or single-node
mode) render as before. State for expand/collapse is local to the
component, keyed by jobID/id - reload starts collapsed.

* fix(galleryop): UpdateStatus preserves Nodes when caller sends none

Real-world bug surfaced by the Phase 4 multi-worker smoke test: the
nodes[] array in /api/operations flickered between a single node at a
time on a 2-worker install. Root cause: the Phase 2 progress bridge
also calls the legacy progressCb -> UpdateStatus(&OpStatus{...}) on
every tick. UpdateStatus then overwrote the entire status pointer,
wiping the Nodes slice that UpdateNodeProgress had just merged in.

Fix: in UpdateStatus, if the incoming op has an empty Nodes slice,
carry forward the previous status's Nodes before storing. Callers
that explicitly populate Nodes still win (their slice replaces the
prior one, no merge across the two code paths).

Two regression specs added pinning both directions of the contract.

* refactor(config): move DistributedConfig.Validate flag names to constants

The negative-duration check map was a wall of literal kebab-case
strings that had to stay in sync with the kong-derived CLI flag names
manually. Move them to a Flag* const block alongside the existing
Default* block so a rename of either the Go field or the CLI naming
convention forces a compile error rather than silent drift.

Sole consumer today is Validate; the constants are exported so future
operator-facing surfaces (e.g. error messages on other validation
paths) can reference them by name instead of repeating the literals.

Tests pin both the literal values (so a future "let's just rename
this" doesn't accidentally regress the CLI flag) and the negative-
duration error message for the new BackendInstall / BackendUpgrade
fields.

* refactor(distributed): extract NodeStatus and Phase enums to constants

Sweep for the same literal-string-as-identifier pattern called out on
the Validate flag names: the per-node install status enum
("queued" | "downloading" | "running_on_worker" | "success" | "error")
appeared as raw literals across managers_distributed.go (10+ sites,
including 3 separate `n.Status == "running_on_worker"` checks),
operation.go, and the test suite. Same shape for the Phase enum
("resolving" | "downloading" | "extracting" | "starting") in the
worker-side progress publisher.

Promote both to exported const blocks:

- galleryop.NodeStatus{Queued,Downloading,RunningOnWorker,Success,Error}
  shared between galleryop.NodeProgress.Status (the wire field) and
  nodes.NodeOpStatus.Status (the in-process per-node summary)
- messaging.Phase{Resolving,Downloading,Extracting,Starting}
  shared between the worker publisher and any future consumer that
  needs to switch on phase

Tests pin both the literal values (so a future "let's just rename" doesn't
silently change the JSON wire) and use the constants in setup (so the
producer side stays drift-protected). Wire-format assertions on the
/api/operations JSON output keep their literals deliberately, so the
constant value can never silently diverge from what the UI receives.

Out of scope for this PR (separate cleanup): the finetune and
quantization job-status enums have the same anti-pattern with 14+
literal sites each, but predate this PR's work.

LocalAI [bot]andEttore Di Giacinto 61bf34ea2f fix(traces): cap captured body size to keep admin Traces UI responsive (#9946)
The trace middleware buffered the full request and response bodies for every
JSON exchange. With a chatty agent-pool RAG workload, /embeddings responses
(large vector arrays) accumulated to tens of MB in the in-memory buffer; the
admin Traces page would then download and parse 40+ MB on every load and on
every 5s auto-refresh, locking the UI in a loading state.

Add LOCALAI_TRACING_MAX_BODY_BYTES (default 64 KiB) that caps each captured
body. The full payload still flows through to the real client; only the
trace copy is bounded. Exchanges record body_truncated and original
body_bytes so the dashboard can show that truncation happened. The cap is
configurable via env, CLI, and runtime_settings.json.

Also unblock recovery: the Traces page now keeps the Clear button enabled
while loading, since "buffer too large to render" is exactly when the user
needs to clear it.

Richard Palethorpe 5d0b549049 feat(gallery): verify backend OCI images with keyless cosign (#9823)
* feat(gallery): verify backend OCI images with keyless cosign

Close a trust gap where a registry compromise or MITM could silently
replace a backend image: the gallery YAML tells LocalAI which image to
pull, but until now nothing verified the bytes came from our CI.

Consumer (pkg/oci/cosignverify):
- New package using sigstore-go to verify keyless-cosign signatures.
- OCI 1.1 referrers API + new bundle format (no legacy :tag.sig).
- Policy fields: Issuer / IssuerRegex / Identity / IdentityRegex /
  NotBefore. NotBefore is the revocation lever — keyless Fulcio certs
  are ephemeral so revocation is policy-side; advancing not_before in
  the gallery YAML invalidates every signature predating the cutoff.
- TUF trusted root cached process-wide so N backends from one gallery
  do 1 fetch, not N.

Plumbing:
- pkg/downloader: ImageVerifier interface + WithImageVerifier option
  threaded through DownloadFileWithContext. Verification runs between
  oci.GetImage and oci.ExtractOCIImage, with digest pinning via
  pinnedImageRef to close the TOCTOU window. Skips the verifier's HEAD
  when the ref is already digest-pinned.
- core/config: Gallery.Verification YAML block.
- core/gallery: backendDownloadOptions builds the verifier from the
  policy; applied on initial URI, mirrors, and tag fallbacks.
- core/gallery/upgrade: the upgrade path now routes through the same
  options builder. A regression Ginkgo spec pins this contract —
  without it, UpgradeBackend silently bypassed verification.
- core/cli: --require-backend-integrity (LOCALAI_REQUIRE_BACKEND_INTEGRITY)
  escalates missing policy / empty SHA256 from warn to hard-fail.

Producer (.github/workflows/backend_merge.yml):
- id-token: write at job scope (PR-fork-safe via existing event gate).
- sigstore/cosign-installer@v3 pinned to v2.4.1.
- After each docker buildx imagetools create, resolve the manifest
  list digest and run cosign sign --recursive --new-bundle-format
  --registry-referrers-mode=oci-1-1 against repo@digest. --recursive
  signs the index and every per-arch entry, matching how the consumer
  resolves a tag to a platform-specific manifest before verifying.

Rollout: backend/index.yaml has no `verification:` block yet, so this
PR is backward-compatible — installs proceed with a warning until the
gallery is populated. Strict mode is opt-in.

* refactor(gallery): plumb RequireBackendIntegrity through config instead of env

The previous implementation re-exported the --require-backend-integrity
CLI flag into LOCALAI_REQUIRE_BACKEND_INTEGRITY via os.Setenv, then
re-read it in core/gallery via os.Getenv. This leaked process state
into the gallery package and made the flag impossible to override
per-call or test without touching the env.

Add RequireBackendIntegrity to ApplicationConfig (with a matching
WithRequireBackendIntegrity AppOption) and thread the bool through
every install/upgrade path: InstallBackend, InstallBackendFromGallery,
UpgradeBackend, InstallModelFromGallery, InstallExternalBackend,
ApplyGalleryFromString/File, startup.InstallModels. Worker subcommands
gain the same env-bound flag on WorkerFlags so distributed-worker
installs honor it consistently with the worker daemon path.

Add a forbidigo lint rule against os.Getenv / os.LookupEnv / os.Environ
to keep the env-leak pattern from creeping back. Existing offenders
(p2p, config loaders, etc.) are baseline-grandfathered by the existing
new-from-merge-base: origin/master setting; targeted path exclusions
cover the legitimate cases — kong CLI entry points, backend
subprocesses, system capability probes, gRPC AUTH_TOKEN inheritance,
test gating env vars.

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

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

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

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

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

Regression tests cover 0.0.0.0, 0.0.0.0:PORT, [::], ::ffff:127.0.0.1,
::ffff:10.0.0.1, file://, gopher://, ftp://, localhost, 127.0.0.1,

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

test coverage. The chat route is FeatureChat-gated (default-on), and
the assistant's in-process MCP server can install/delete models and
edit configs — the wrong handler change would silently turn the LLM
into a confused deputy.

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

passthrough. A new endpoint shipped under a brand-new prefix — or a
new path that simply isn't on the prefix allowlist — would be
reachable anonymously.

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

regression there is the difference between "regular user reads their
own data" and "regular user reads anyone's data via ?user_id=victim".

  - effectiveUserID ignores ?user_id= for unauthenticated and RoleUser
  - effectiveUserID honours it for RoleAdmin and ProviderAgentWorker

* feat(http): XSS hardening — CSP headers, safe href, base-href escape, SVG sandbox

Several closely related XSS-prevention changes spanning the SPA shell, the
React UI, and the branding asset server:

- New SecurityHeaders middleware sets CSP, X-Content-Type-Options,
  X-Frame-Options, and Referrer-Policy on every response. The CSP keeps
  script-src permissive because the Vite bundle relies on inline + eval'd
  scripts; tightening that requires moving to a nonce-based policy.

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

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

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

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

the same shape on its prefix-trailing-slash redirect.

a single '/', no protocol-relative '//' opener, no scheme, no
backslash, no control characters. Apply at both consumers; misconfig
trips the validator and the header is dropped.

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

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

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

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

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

* fix(react-ui): refresh i18n strings to reflect 12-char password minimum

The translations still said "at least 8 characters" everywhere — the
client-side toast on a too-short password change told the user the
wrong floor. Update tooShort and newPasswordPlaceholder /
newPasswordDescription across all five locales (en, es, it, de,
zh-CN) to match the real ValidatePasswordStrength rule.

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

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

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

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

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

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

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

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

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

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

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

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

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

Same Go package powers two modes:

  pkg/mcp/localaitools/

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

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

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

Wiring:

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

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

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

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

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

UI:

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

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

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

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

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

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

This pulls them into typed constants:

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

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

No behaviour change. All tests pass with -race.

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

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

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

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

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

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

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

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

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

Two related leaks:

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

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

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

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

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

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

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

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

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

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

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

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

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

Three small cleanups landing together:

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

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

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

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

The repo convention (per core/http/endpoints/localai/*_test.go,

them stand out and stripped the BDD structure the rest of the suite

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

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

                              one run).
    httpapi/client_test.go — Describe("httpapi.Client against the
                              LocalAI admin REST surface"),
                              Describe("ErrHTTPNotFound"),
                              Describe("Bearer token")
    inproc/client_test.go  — Describe("inproc.Client cancellation")

  core/services/modeladmin/
    config_test.go         — Describe("ConfigService") with sub-Describes

    atomic_test.go         — Describe("writeFileAtomic")

  core/http/endpoints/mcp/
    localai_assistant_test.go — Describe("LocalAIAssistantHolder")

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

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

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

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

Add a coverage test plus stronger docs:

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

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

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

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

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

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

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

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

Tightened scope:

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

Kept with documented rationale:

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

Side wins:

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

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

All tests green with -race.

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

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

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

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

The LocalAI Assistant doc still described the older iteration:

- The in-chat toggle was renamed from "Admin" to "Manage" (the badge is
  now "Manage mode" and the home page exposes a "Manage by chat" CTA).
- LOCALAI_ASSISTANT_BOOTSTRAP_MODEL / --localai-assistant-bootstrap-model
  and the bootstrap_default_model tool were removed — admins pick a model
  from the existing selector instead, no env-var configuration required.
- The shipped tool catalog includes import_model_uri but didn't appear in
  the doc; bootstrap_default_model appeared but no longer exists.
- The Settings → LocalAI Assistant runtime toggle wasn't mentioned as the
  preferred way to disable without restart.

- API endpoints: GET /backends/upgrades, POST /backends/upgrades/check, POST /backends/upgrade/:name
- CLI: `localai backends upgrade` command, version display in `backends list`
- BackendManager interface: add UpgradeBackend and CheckUpgrades methods
- Wire upgrade op through GalleryService backend handler
- Distributed mode: fan-out upgrade to worker nodes via NATS

* fix: use advisory lock for upgrade checker in distributed mode

In distributed mode with multiple frontend instances, use PostgreSQL
advisory lock (KeyBackendUpgradeCheck) so only one instance runs
periodic upgrade checks and auto-upgrades. Prevents duplicate
upgrade operations across replicas.

Standalone mode is unchanged (simple ticker loop).

* test: add e2e tests for backend upgrade API

- Test GET /api/backends/upgrades returns 200 (even with no upgrade checker)
- Test POST /api/backends/upgrade/:name accepts request and returns job ID
- Test full upgrade flow: trigger upgrade via API, wait for job completion,
  verify run.sh updated to v2 and metadata.json has version 2.0.0
- Test POST /api/backends/upgrades/check returns 200
- Fix nil check for applicationInstance in upgrade API routes
