* Find the Sandbox guest image in the executable, not its build info

The Sandbox smoke checked that the packaged executable carries the
guest image by looking for -X main.guestImage in go version -m. The
package is built with -trimpath, and with -trimpath Go leaves -ldflags
out of the build info, so the check failed on every gvisor run,
although the image was linked in.

Look for the reference in the executable instead: the value of
SANDBOX_GUEST_IMAGE when it is set, any digest reference otherwise.
package.sh had the same check for an executable built elsewhere; it
now looks for its own reference the same way.

* Answer a network card the limit refuses with one precise reason

A card that waited while the administrator's limit went down was
refused on the first click with 400, and every later click was a bare
409, so a stale card looked like a conflict loop. A refused card now
answers 400 egress_above_ceiling every time, the same answer sent twice
is one answer (204), and another answer to an answered card is 409
already_answered. The chat view marks a card the limit cannot admit
with above_ceiling.

When the limit is off, or below the chat's preset, the note of the turn
and the block line of the proxy now say that the server's setting
blocks the network and no approval changes it, so the model reports it
instead of waiting or retrying.

* Explain a blocked Sandbox network instead of offering dead buttons

A card the limit cannot admit shows why network access is off or
limited, and who can change it, with a link to Settings > Tools >
Sandbox network for administrators. The buttons of a card disable while
an answer is sent, and a failed answer reads the card again. The
Network row says why its choices are capped. Settings opens a group
from ?group=. Strings are translated in all nine locales and the chat
and add-on docs describe the new behaviour.

* Add an always-allowed hosts list to the Sandbox network

The extra registries setting only widens the package registries, so a
one-off host needs the approval card in every chat. The new admin
setting chats_egress_allowed_hosts lists exact hosts (optionally
host:port to pin a port) that a chat reaches whenever its effective
preset is registries or all.

The list sits in the same decision as the presets: the ceiling still
caps it, the ports setting still applies, and a private, loopback,
link-local or metadata address still needs the private switch and an
administrator's rule or answer. Each use is audited with the reason
allowed_host. Hosts are validated like the extra registries (lower
case, punycode, no scheme, path or pattern, at most 64) and an IP
literal is refused unless the private switch is on.

get_chat_egress and the chat egress view return the list; no MCP tool
writes it, as for the extra registries.

* Let users delete from the Trash for good

A delete only set a tombstone, so the Trash grew without end and
nothing could free the space of a deleted file.

The workspace stores gain a Purger: it erases the deleted nodes of
some change sets, or of a whole folder, with their journal rows, the
change sets that nothing is left in, and the blobs that no row refers
to. Both stores implement it and pass the same contract specs. A blob
is removed after a grace period, and only if it is still unused then,
so an upload of the same bytes in flight keeps them.

DELETE /api/chats/files/trash empties the user's Trash and
DELETE /api/chats/files/trash/{rev} deletes one entry. Both are scoped
to the caller's home. The Trash listing now gives files, folders and
bytes per entry and for the whole Trash. The file tools of a chat
cannot reach any of this.

Assisted-by: Claude:claude-sonnet-5-5

* Add Empty Trash and Delete permanently to the Files page

The Trash tab shows what it holds, with an Empty Trash button that is
off while the Trash is empty and a Delete permanently button on each
item. Both ask in the page first and say how many files and folders and
how much space they remove. Texts are translated in all nine locales.

* Fall back to Brave Search and Bing when DuckDuckGo asks for a captcha

DuckDuckGo answers some servers with HTTP 202 and a bot check (the
"anomaly" page) instead of results. The parser read that page as "no
results it could read", so web_search failed for every query.

The keyless search is now a chain: DuckDuckGo, then the result page of
Brave Search, then the result page of Bing. Each page has its own
tolerant parser (title, URL, snippet; Bing's /ck/a links and DDG's uddg
links are unwrapped) with saved fixtures.

A bot check is a typed error (ErrChallenged), and a 403 or 429 is
ErrBlocked. Both wrap ErrProvider. A Fallback with a cool-down skips a
challenged or blocked provider for a few minutes, so each search does
not wait for it first; when every provider is cooling down, all are
asked again. Fallback.SearchAttempts and TestEach report what each
provider did (ok, no_results, challenged, blocked, timeout, error,
skipped).

The error a model reads now lists what was tried and what each provider
did, then where an administrator fixes it.

safehttp keeps the status code of an answer (Response.StatusCode) and
of a refusal (StatusError, still ErrStatus for errors.Is).

* Use the keyless search chain in the chats and test each provider

The built-in web_search now searches with DuckDuckGo, Brave Search and
Bing in turn when no SearXNG instance is set. A new runtime setting,
chats_web_search_providers, sets the order (searxng, duckduckgo,
brave_html, bing_html) and leaves a provider out. Empty keeps the old
choice: SearXNG alone when an instance is set, so its queries do not
reach the public engines unless the administrator lists them.

POST /api/chats/admin/web/test asks every provider of the order and
returns what each did in "providers" (ok, no_results, challenged,
blocked, timeout or error, with the reason), next to the first answer.
Settings > Tools has a Test search on the web_search row that shows it,
and the provider list is checked on the page and by the server.

The cool-down of a challenged provider is kept per frontend, like the
cache and the limits; web.md says why.

Docs: web.md (providers, chain, bot checks, privacy, how to fix it with
SearXNG or the Web add-on) and runtime-settings.md. Strings in the
nine locales. Swagger regenerated.

* Try the mirror library alone in the reinstall recovery spec

The spec adds a second library with the same URL and expects an
install from it to keep the retained data apart. Since two enabled
libraries that list one add-on are a conflict, the reinstall from the
original library then failed with library_conflict, and the install
from the mirror failed for that reason instead of the trusted identity.

Switch the original library off while the mirror is tried, check that
the mirror is refused for its identity and not for a conflict, then
switch the mirror off and the original on for the reinstall.

* Pause a chat turn at the step limit and offer Continue

A chat turn ran at most 10 rounds of tool calls, the default of the
harness, because nothing set a limit. A multi-step task (read some
files, run commands, write a result) stopped half way, and the person
saw an answer that looked final.

The limit is now the runtime setting chats_max_iterations (1 to 500,
default 40, Settings > Tools); a model's agent.max_iterations still
wins. When the tool loop reaches it, the harness sends a paused event
with the limit, and the turn ends with last_turn "paused". A paused
turn counts as finished: waiting messages start the next turn and a
sub-agent reports back. The status line says "Paused, after 40 steps"
and has a Continue button, which sends a message that asks the model
to go on.

A claim that found no waiting message released the chat as "done",
which hid a pause. It now keeps the status the chat had.

* Edit the always-allowed Sandbox hosts in Settings > Tools

Add a list editor for chats_egress_allowed_hosts next to the extra
package registries: the hosts are tags with a remove button, an input
adds one on Enter, comma or Add (a pasted list adds them all), and the
reason an entry is refused shows under the input, with the count out
of 64. The same checks stop Apply on a bad entry, and the server still
has the last word.

The chat's Network panel lists the hosts read only and the row says
how many an administrator always allows while the chat's network is on.
The help text of both settings now says how they differ. Strings are
translated in all nine locales.

* Document the always-allowed Sandbox hosts

Describe chats_egress_allowed_hosts in the runtime settings page, the
network section of the add-ons page (including the allowed_host audit
reason and how the list differs from extra registries) and the chats
page.

* Let a chat edit, pause and delete the person's triggers

A chat could propose a trigger and list them, but not change one: the
Triggers page and the API could. list_triggers now gives each trigger a
stable ref (not its id) and shows the prompt of one trigger only when
asked. update_trigger and delete_trigger store a change record in the
trigger table: an edit or a delete waits for Apply or Delete on a card,
a pause or a resume applies at once with a receipt. An applied change
can be undone for a day; a delete restores the trigger with its id.

Change records are rows in the database, so every frontend shows and
answers the same card. The new routes under /api/chats/triggers/changes
serve the card and are gated by the triggers feature.

Assisted-by: Claude:claude-opus-5-5

* Show the trigger changes a chat asks for as cards

An edit lists each changed field before and after with Apply and
Dismiss, a delete shows the trigger and its last run with Delete and
Keep, and an applied change is a receipt with Undo. The cards sit below
the message text like the proposal card, and read their state from the
server so a reload shows the same answer.

* Add a Test search button to the web tools settings

POST /api/chats/admin/web/test existed, but no page called it and the
docs showed only curl. The web_search row of Settings > Tools now has
a Test search button. It runs one search with the applied settings and
shows the provider with its first results, or the error a chat would
read.

Assisted-by: Claude:claude-opus-5-5

* Describe undo per tool call in the chats docs

The docs said the checkpoint line of a turn carries the change set of
the turn. A turn checkpoint is taken only by a chat with a VM sandbox,
which the service never sets up, so that rev is always 0. What ships
is one change set per file tool call, with a files_change card on its
tool line. The docs now say so and how to undo a whole turn.

Grouping a turn's changes into one change set in the file store is
left for later: it touches the file store's revisions and the undo of
shared folders.

* Mount the skill folders read-only for the built-in bash

The built-in pdf skill ships scripts, but the commands saw only the
home and the shared folders, so the model could read the scripts and
not run them. The built-in bash now mounts the three skill layers
read-only, at the names the file tools already use: shared-skills,
shared-builtin-skills and shared-addon-skills. A shared folder named
skills moves to "shared-skills 2", so the two never collide.

A read-only mount with subfolders made every command report its
folders as changes the mount refused, because the host backend lists
every folder of its work tree. A folder alone is no change: both
stores now refuse only files, whiteouts and opaque folders there.

The Sandbox add-on mounts only the home; the docs say to copy a
script there first.

* Find the add-on that runs commands by what it shadows

The chats knew the add-on that runs commands from a per-process cache,
filled with the Sandbox's own tool name the first time a chat listed
its tools. Another add-on that replaces bash did not count, so skills
that need commands showed as unavailable. The admin network view read
the same cache: after a restart it said no Sandbox serves until
someone chatted, each frontend of a cluster could answer differently,
and a removed add-on stayed listed.

The tool that runs commands is now the one that shadows bash, as the
spec asks. sandboxRunTool and the cache are gone. The stand-in of an
add-on that cannot work carries the built-in tools it replaces, and
the admin view asks the add-on host which add-on serves bash now: the
pinned one or the oldest running install, and none when the pinned one
is stopped.

Assisted-by: Claude:claude-opus-5-5

* Show international host names in punycode in the network checks

The card-spoofing defence of the sandbox network asks for host names
in their ASCII form, but CheckHost passed Unicode names through. A
look-alike name reached the consent card as text that reads like the
real site.

CheckHost now converts an international name with the IDNA lookup
profile and refuses one with no valid ASCII form. The conversion runs
before the address checks, so full-width digits that spell a loopback
address are refused as loopback.

* Keep the seeded Studio and Talk pins until the add-ons are installed

The upgrade pins Studio and Talk for existing accounts, but both are
add-ons that an administrator installs later. The sweep marked a pin
whose add-on is not installed as missing and deleted it after 30
days, so an administrator who installed Studio late found the seeded
pins gone.

The sweep now records the first time a seeded add-on is present, in
the table of seed runs or the pins file. A seeded pin keeps no clock
until then, and a mark that an older sweep set is cleared. After the
first install the pin follows the retention rule as before.

* Fix two small labels of the Skills and Backends pages

On the Skills page, the skill of an add-on that is not chosen said
"Replaced by <add-on>", the label of a built-in skill that an add-on
serves. It now says "Not active: <add-on> provides it", as the add-on
skills spec asks.

On the Backends page, Clear filters on an empty Installed search left
the library filter set, so the list stayed empty. It now clears the
library filter too.

* Tell the model when no network card can appear

Each turn told the model that a blocked host asks the user. No card
appears when the ceiling is off or no wider than the chat's preset, in
an unattended run or in a sub-agent, so the model waited for an answer
that could not come.

The line now says that a blocked host is refused and nothing asks the
user in those cases, so the model names the host it needs in its
answer.

* Translate six Backends and preview labels in every locale

check, reinstallBackend, deleteBackend and filterLabel of the Backends
page and the label and failed text of the file preview showed in
English in the eight other locales. They now have translations, and
the i18n baseline goes down to match.

Also fix a comment of the home composer that still named the removed
Canvas chip.

* List the admin routes that have no assistant tool, with the reason

The admin oversight routes of saved agents, triggers and connectors
had no MCP tool and no recorded reason, and the other deliberate skips
lived only in code comments. coverage_test.go now keeps them in
adminRoutesWithoutTool with a reason each, and a spec checks that no
route there is also wrapped by a tool. The contributor checklist names
the map.

The tool catalog of the assistant docs said it matched the real one
but missed most tools added since. It now lists every tool, read-only
and mutating, and the actions that stay in the web interface.

* Close the doc and registry gaps of the chats and add-ons

- /api/agent/* answers 404 with the chats_off reason when the chats
  are off, as /api/chats/* and /api/workspace/* do.
- The add-ons docs get an upgrade section: Studio and Talk are
  add-ons, nothing is preinstalled, and users need the addons feature,
  which the upgrade does not grant. It says how an administrator
  installs them (also from a private library) and grants the feature,
  and carries a paragraph for the release notes.
- The migration page no longer lists fork, edit, the chat settings and
  the token counters as removed.
- Runtime settings document chats_vision_model,
  chats_transcription_model and the skill keys of
  chats_tool_providers.
- The docs show POST /api/chats/files/folders,
  GET /api/chats/files/history and the allow route of a connector
  sender.
- The in-tree specs get amendments where the shipped design differs.
- A route test of the tagged suite still set the removed Runs field.

* Look for the kit empty state in the backends regression spec

The Backends page now draws the shared EmptyState of the kit
(ui-empty), not the old dk-empty block, so the regression spec of the
gallery suite found no empty state after a search with no match.
Check the kit's no-results form and its title.

* Ignore a features request that outlives its page in the add-on stubs

stubAddonRoutes answers /api/features by fetching the real flags and
turning add-ons on. A spec that ends while the page polls, like the
one that checks that a viewer without the feature never reads the
list, left that fetch in flight, and Playwright failed the spec with
"route.fetch: Target page, context or browser has been closed" after
its checks had passed. Abort the request when the fetch fails because
the page is gone.

* Bring the gallery-ui case inventory up to date

The suite lists the node unit cases of addons.test.mjs and the
Playwright specs of addons-gallery.spec.js. The inventory missed the
unit cases added since it was written, and one spec was renamed when
the legacy switch came in ("hub: the Add-ons tab appears only for an
account that holds the feature" is now "hub: under the legacy switch
the Add-ons tab appears ..."). The list comes from a local run of
both parts against the UI test server.

* Read spreadsheets, documents and slides in read_document

read_document said "file.xlsx has no text layer; it may be a scan" for
workbooks that some Python libraries write. Their workbook gives the
sheet as an absolute part name (/xl/worksheets/sheet1.xml) and the
cells as inline strings. The text extractor of the harness joined
"xl/" with that name, found no sheet, and returned no text; the tool
then took any empty result for a scanned PDF.

The new package core/services/studio/extract has one entry point,
Extract(ctx, name, data), that returns the text and the structure it
read, for read_document now and for a file indexer later. Office files
go through the files preview reader, which resolves both kinds of part
names and reads inline strings:

- a workbook comes sheet by sheet, rows as tab-separated lines, up to
  2000 rows and 50 columns a sheet, with a note for a cut sheet;
- a Word document gives headings, list items, paragraphs and tables;
- a presentation gives each slide with its title, text and notes.

PDF and EPUB keep the harness extractor. Only a PDF with no text is
reported as a probable scan; an empty Office file is reported as empty.
The preview reader now keeps a Word table as one block with its rows,
and the preview pane draws it as a table.

* Add the missing explorer, library and tools translations

Eight locales had no explorer.json, library.json or tools.json. The
browser asks the server for every namespace of the language it shows,
so an Italian page that used the library answered 404 for
/locales/it/library.json on every load and fell back to English.

The 24 files now exist, translated, with every key of English. The
locale gate counted a missing file as missing keys, which the baseline
allowed. It now fails on a missing namespace file whatever the
baseline says, and the baseline is 24 entries shorter.

* Back off while the add-on service is unavailable

A page that followed an add-on upgrade read the operation every two
seconds, up to 300 times. While the add-on service restarted, each read
waited for its timeout and answered 503, so the log of one session had
48 failed dispatches in a row, and the page only showed the upgrade as
running. The Sandbox state of a chat's Tools menu read once and, on a
503, said nothing more.

The reads of an operation now back off while the service does not
answer: 2, 4, 8, then up to 30 seconds. The upgrade entry says that it
waits for the add-on service and when it checks again, in Activity and
in the details, which also get a Check now button. The Tools menu says
that the Sandbox is starting and reads its state again with the same
back-off, kept for the page, so opening another chat does not ask
again before the wait is over.

* Start a chat with its switches and list them before it exists

The composer of a new chat could not show the Tools and Skills menus,
because the lists and the switches belong to a chat. A chat started
from Home therefore always began with every tool and skill on.

- POST /api/chats takes switches: the add-ons, MCP servers and
  connectors, built-in groups and skills that are off, and the opt-in
  groups that are on. They are checked as the PUT endpoints check them
  and stored with the new record, so the chat never exists without
  them; a bad entry refuses the request and creates nothing. The SQL
  store now writes these lists on create too.
- GET /api/chats/draft/tools and /api/chats/draft/addons list what a
  chat on a model, with a saved agent, could use, every switch in its
  default state. They refuse what create refuses: an unknown or
  forbidden model, an agent without the agents feature, another
  user's agent.

Document both in the chats page and regenerate the swagger.

* Give Home the composer of the chat page

Home drew a smaller message box than the chat page: no files, no
agent, no Tools or Skills menus, no paste to attach, no rich model
list, and its text was lost on a reload. A chat started there could
not be set up before its first message.

Move the composer wiring out of the chat page into one place that
both pages use:

- useChatComposer holds the draft (text and files), the model and the
  saved agent of a new chat, the chat models, the switches and what
  attaching and pasting do.
- ChatComposer draws the model list (fit, vision, memory bar), the
  agent picker, the Tools and Skills menus, the attach buttons,
  dictation, the add-on slot and the vision notice over HomeComposer.
- useChatSwitches has a draft mode: before the chat exists it lists
  from the draft endpoints, a switch changes only the screen, and the
  choices go with the create request. They outlive a change of model
  or agent.

Home now creates the chat with the model, the agent and the drafted
switches, sends the first message with its files and opens the chat.
When the message cannot go, the new chat is removed and the text and
files stay on Home. Its text is kept in the browser across a reload.
Home also gets the shortcuts row, the notices of the chat page and the
line that says whether the model is loaded. Its own slash actions,
widgets, examples and first-run steps stay.

The empty chat page gets the same draft menus. On a phone the chips
of both wrap to a second row, and the Tools and agent menus open as a
sheet from the bottom, as the skills picker does.

* Move add-on settings to the add-on's own page

The settings.sections slot drew every add-on's settings at the end of the
global Settings page, and the Sandbox and Web sections were unstyled: the
add-on UIs used class names the host does not define (btn, btn-primary)
and bare inputs, the SDK offered no form primitives, its muted token
named a property that does not exist, and the slot root was an
inline-flex span that laid a form out in a row.

An add-on's settings sections now render on the Settings tab of its
details on the Add-ons page (/app/addons?detail=<id>&view=settings),
narrowed to that add-on, for administrators only. An add-on page gets a
host Settings link to that tab. The Settings page no longer draws the
slot: an Add-ons group, shown when an add-on has settings, lists those
add-ons with a link each. The old #ad-section-<addon>-<id> anchor
redirects to the tab once the apps list is read. Server settings of an
add-on's feature stay on the Settings page; the tab shows them under
"Server settings for this add-on", with a read-only summary of the
Sandbox network and links to ?group=tools#settings-egress and
#settings-builtin-tools.

The SDK gets a settings kit in sdk.ui (Section, Field, Select,
TextInput, Switch, Choice, StatusChip, Callout, List/ListRow, Code,
Actions, Table, ExternalLink), drawn with host classes and tokens, and
more theme tokens. The Sandbox and Web sections are rebuilt with it:
backend rows with a status chip and the raw reason collapsed in a code
block, a backend choice with one line per option, and the AppArmor and
user-namespace hint (with a docs link) only for the gVisor
"exit status 128 ... cannot read client sync file" failure.

The Settings page showed "Changed, default 30, Reset" next to a 0 for the
audit retention, and the same for the Sandbox network limit, preset and
ports: the server stores 0 or an empty value for a setting never set.
Those fields now read that value as their default, and the retention
input has its unit and bounds.

* Adapt the add-on runtime specs to the new navigation

Three specs of the esm-ui suite still assumed the old shell:

- the Add-ons tab that lists the pages add-ons declare is part of the
  legacy layout, so the navigation spec found no hub subnav; it now
  sets the legacy switch on the server's flags for that page;
- the sidebar has no "Chat" link any more, so the unsaved-edits spec
  could not leave the page; it leaves through Home in the primary
  navigation;
- the shell keeps a notification stream open, so the network never
  goes idle and the spec for a member without the feature waited out
  its timeout; it waits for the server's switches, the account and
  the shell instead.

* Name the legacy Add-ons tab unit case as the esm unit tests do

The esm-ui inventory listed "unit: registry: the Add-ons tab lists
page links only when the registry has usable add-ons", but the unit
test is named "the legacy Add-ons tab lists ...", so the suite could
never match its inventory. Use the name the test prints.

* Say on the Collections page when the embedding model is missing

At startup the server opened a collection and its first embedding call
got 404 from POST /embeddings. The collections embed through this
server's own API with collections_embedding_model, the default
granite-embedding-107m-multilingual, and that model was not installed.
Nothing told the user: uploads and searches just failed.

GET /api/collections now also returns embedding_model and
embedding_model_installed (a loaded configuration of that name, or a
model file of that name). When it is missing, the Collections page
says "No embedding model installed", names the model, and gives an
administrator a button that opens the Models page with a search for
it.

* Report modified times and the upload limit in folder listings

The Files page could not sort by date or show when a file changed: a
folder listing had no time. It also learned the upload limit only after
it had sent the whole file. The default server body limit is 15 MB,
lower than the 256 MiB a workspace file may have, so a large upload
failed late and without a clear reason.

Each listed entry now has "modified", the time of the change set of
its revision. Both workspace stores fill it in List: the JSON store
from its in-memory change sets, the database store with one query per
batch of revisions. The listing also has "max_file_size", the smaller
of the workspace limit and the server body limit, so a client can
refuse a larger file before it sends any byte.

The store contract suite checks the new time against the history, and
the route tests check both fields.

* Add a sortable file list with thumbnails for the Files page

The building blocks of the new file browser, used by the page in a
later change:

- fileBrowser.js: the kind of an entry from its extension, the order
  (folders first, natural and case-insensitive names, then size,
  modified time or type), the filter of a folder, dates in words with
  the full date for a tooltip, the Shift range, the arrow moves of a
  list and of a grid, type-to-find, names that do not clash, why a
  name cannot be used, the name of a pasted screenshot and the view
  settings read back from storage.
- FileList: a grid with sortable column headers or a grid of tiles
  with image thumbnails, a check box per row, a row menu, inline
  rename with the reason a name is refused, rows that can be dragged
  onto folders, and the keyboard: arrows, Shift, Space, Enter, F2,
  Delete, Ctrl+A, Escape, Backspace and typing a name.
- MoveDialog: a folder picker that walks the tree and refuses a move
  into the moving folder itself.
- ActionMenu can open at a point with no trigger (a right click), and
  its trigger can take another icon and class (a split button).
- fileSize also writes gigabytes.

* Add an upload queue with progress, cancel and retry

An upload of the Files page was one fetch per file in a loop: nothing
showed while it ran, one failure stopped the rest, and leaving the
page lost it.

- uploadQueue.js keeps every upload outside React: queued, sending
  with the bytes sent and a smoothed rate, done, failed with a reason
  and whether Try again can help, or canceled. Two files go at once.
  It lives for the whole app, so opening another folder or page does
  not stop an upload.
- filesApi.uploadWithProgress sends the same PUT with XMLHttpRequest,
  which reports upload progress and can be aborted. The server already
  streams the body into the store; nothing changes there.
- useUploads reads the queue and asks before the tab closes while a
  file is on its way.
- UploadTray shows the queue at the bottom of the page: the total and
  the time left, each file with its progress, speed and time left,
  Cancel, Try again with the reason, and a done state that fades out.
  A live region tells a screen reader when uploads start, fail and
  end.
- ConflictDialog asks what to do when an upload has the name of a file
  in the folder: replace it, keep both, or skip it.
- dropFiles.js reads dropped folders with their paths.

* Rebuild the Files page as a file browser

The Files page was a list of links: the store's byte order, the same
icon for every file, three icon buttons on every row, no progress on
an upload, no selection, and on a phone a preview that opened below
the whole list.

Browsing: a breadcrumb that folds a deep path, sortable columns (name,
modified, type, size) with folders first, a list or a grid of
thumbnails, both kept per user in the browser, a filter of the open
folder with a search of every file on Enter, type icons, human sizes,
dates in words with the full date on hover, and Back and Forward
between folders.

Uploads go through the upload queue and its tray: the Upload button
or its folder menu, drops of files and folders anywhere on the page or
onto a folder row or crumb, and paste. A clash asks to replace, keep
both or skip; a file over the server limit is refused before it is
sent.

Selection and actions: click, Ctrl and Shift, check boxes, a selection
bar (Download, Move to, Move to Trash; at the bottom of the screen on
a phone), a row menu and a right click, inline rename and new
folder or file, drag to move, the keyboard, and a toast with Undo for
a delete, a move and a rename.

States: a skeleton on the first load, an error with Try again, empty
states that say how files get here, and a no-match state. The preview
uses the side pane: docked on a wide screen, a sheet on a phone, with
the same actions as the row menu. Trash, History and the Managed by
LocalAI group stay as they were.

Every new string is in the nine languages. The page uses design
tokens only (seven raw font sizes fewer). The specs cover sorting,
the filter, the views, selection and bulk actions, the keyboard, the
menu, rename checks, drag to move, drops, paste, clashes, the size
limit, upload progress, cancel and retry against the real server, and
the error states.

* Fix two specs that fail on the integration branch

The Describe spec of the egress package checked that the no-card line
does not contain "asks the user", but that line says "nothing asks the
user". It now checks for the sentence that promises a card.

The context meter spec gave the chat a 4k context window. The tool
schemas of the chat now take 3k of it, so the turn stopped before the
model request. The spec uses a 16k window.

Assisted-by: Claude:claude-opus-5-5

* Translate the always-allowed hosts note of the chat network row

The three egress keys of the always-allowed hosts were only in English,
so the locale check failed for every chats namespace. The workspace
namespaces now miss two keys fewer, so their baseline goes down too.

* Bring the contracts and host-slots case inventories up to date

The contracts suite has eight new specs for the check of a tool that
shadows a built-in. The host-slots suite runs the unit case of the file
preview slot, which the inventory did not list.

Assisted-by: Claude:claude-opus-5-5

* Add the design of the file text index

The search of the chats' files reads only small UTF-8 text files, so a
PDF or an Office file is found by name only. The design extracts the
text when a file is written, keeps it in LocalAI's own store keyed by
node and hash, checks access at query time and runs one indexer per
cluster under an advisory lock.

Assisted-by: Claude:claude-opus-5-5

* Give extracted documents their pages, sheets and slides

Extract now says where each page, sheet and slide starts in the text,
so a search hit can name its page or sheet. A PDF page starts with a
"## Page N" line, as sheets and slides already start with a heading.
A PDF also stops at a page limit (200 by default) and at the text
limit, which it ignored before, and a panic of the reader is an error.

The test fixtures move to extracttest, with a real text PDF and a
workbook with shared strings, so other packages can build the same
documents.

Assisted-by: Claude:claude-opus-5-5

* Add a store for the text of workspace documents

textindex keeps one entry per workspace node: the text read from a
PDF or Office file, the hash it was read from, its pages or sheets and
its status (pending, ready, failed, skipped), plus the cursor of the
indexer in the workspace journal.

The GORM store keeps a lower-cased copy of the text, so SQL and the
Go matcher agree on every script, and searches it with FTS5 and the
trigram tokenizer on SQLite or a pg_trgm index on PostgreSQL. Without
them it scans the column. The JSON store keeps the metadata in memory
and each text in its own file, and scans the texts. One contract
suite runs on JSON, SQLite and PostgreSQL.

Assisted-by: Claude:claude-opus-5-5

* Index the text of new and changed workspace documents

The indexer tails the workspace journal from a cursor kept in the text
store. A write of a PDF, Word, Excel or PowerPoint file marks it
pending (the same hash only follows the path), a delete removes the
entry and a move rewrites the paths below a folder. Then it reads the
pending files two at a time, with a timeout, a size cap, a page cap and
a text cap, and stores ready, failed or skipped. A panic of the reader
fails the file, not the pass. The same content is read once.

The first pass starts at revision 0, which indexes the files that were
there before, in bounded steps that resume from the cursor. Enqueue
marks an upload pending at once and Forget drops the entries of nodes a
purge erased. In a cluster each pass runs under a new advisory lock,
so one frontend reads.

Assisted-by: Claude:claude-opus-5-5

* Search and read the text of documents in the chats' files

search_files and GET /api/chats/files/search now also search the text
index: after the name and text-file hits come lines of PDF, Word, Excel
and PowerPoint files, as path (page 3, line 40): text, with the sheet or
slide where a document has them. Each entry is shown only when the
caller may read its file now and the file still has the content the
text came from. Documents keep up to a third of the hits. When files
below the path are still pending, the answer says so instead of
"Nothing found.", and the REST result has indexing.

read_file returns the text of a PDF or Office file with the usual offset
and limit, from the index when it matches the file and read on the
spot otherwise. An upload and a write of a chat tool queue the file at
once, and emptying the Trash drops the entries of the purged files.

Assisted-by: Claude:claude-opus-5-5

* Start the file text index with the files and add its settings

With files on, the server opens the text store next to the workspace
index (the auth database, or a folder under the data path) and starts
the indexer. A chat worker searches the index but runs no indexer.

chats_index_files (default on) switches the reading off and
chats_index_max_text_bytes (2 MiB by default, 64 KiB to 16 MiB) caps
the text kept for one document. Both apply at the next pass, and both
are rows of Settings > Tools.

Assisted-by: Claude:claude-opus-5-5

* Show the page, sheet or slide of a document hit on the Files page

Search all files now lists hits inside PDF and Office files with their
page, sheet or slide instead of a line number of the extracted text,
and says how many documents are still being indexed. The strings are
in all nine locales.

Assisted-by: Claude:claude-opus-5-5

* Test finding an uploaded PDF by its words through the routes

The PDF has a generated name and is uploaded with the REST upload. The
search route first reports it as being indexed, then finds it on its
page after a pass of the indexer, and so does the search_files tool of
a chat. Another user finds nothing.

Assisted-by: Claude:claude-opus-5-5

* Document the search inside documents

The chats page says what the index reads, where the text is kept, who
finds it, which search engine each database uses, the two settings,
the backfill and the single-runner mode in a cluster, and how
search_files and read_file answer for documents. The API instructions
and the PDF skill say the same in short.

Assisted-by: Claude:claude-opus-5-5

* Test the indexer on the JSON workspace store

A server without a database keeps the workspace and the text in JSON
files. The indexer follows the uploads, a folder move and a delete in
that journal as it does in the database one.

Assisted-by: Claude:claude-opus-5-5

* Read all of a long document with read_file

The index keeps the first chats_index_max_text_bytes of a document, so
read_file used to stop where the index stopped. It now uses the index
only when it holds the whole text, and reads the document again (up to
16 MiB of text) when the index cut it.

* Start bash in the user's home

The Sandbox's bash and the built-in bash started in /workspace, the
folder that holds the mounts, so a model that ran a script by a
relative path failed and a file it saved there was lost. A call now
starts in /workspace/home, the folder of the user's files: a relative
path is the same file the file tools see. The tool descriptions and
the commands block of every turn say where a call starts and that
only what is saved there is kept. The built-in bash says that the
/workspace paths do not exist on the host and that a shared folder is
next to the home.

Assisted-by: Claude:claude-opus-5-5

* Name files in tool results by the path the model uses

write_file, edit_file and search_files named a file of the home by its
path in the home ("/scripts/build.py") while the model had written
/workspace/home/scripts/build.py, and a model took the two spellings
for two files. The results now give the path the model uses, and
move_file says where it moved the file to. The cards and the change
notes keep the path in the home.

Assisted-by: Claude:claude-opus-5-5

* Name the paths a command's commit did not save

The result of a bash call ended with "N file(s) changed in your files
meanwhile; the sandbox's version was kept as a copy" for every path the
commit refused, also for a file written outside the user's files,
where no copy is kept. It now has one line a path, with the path as
the guest sees it, the reason, and the path of the copy when the store
kept one, so the model and the user can act on it. The host returns
the paths and the copy to the Sandbox add-on relative to the user's
files, as its mounts are.

Assisted-by: Claude:claude-opus-5-5

* Show the files a command saved under its step

A document that a script wrote with bash reached the user's files, but
the chat showed nothing: only the file tools put a file on their step,
and the Sandbox committed for no chat, so the chat's file list, the
chips under the answer and the preview pane never saw the file.

The host now commits a Sandbox call for the chat that ran it (the
action resource of the request names the chat). After each bash call,
of the Sandbox or of this machine, the chat reads the change sets of
the chat that the call made from the shared store and puts the files
on the step's card, next to the card that says who served the call
(session.SetToolFiles; files with path, change set and op on the
card's new files field). The step lists them as chips that open the
preview pane, the chat's clients are told that its files changed, and
the files reach the file list, so the answer gets its chips and the
pane opens on the newest one, as for write_file.

* Keep JSON out of the answer of a trigger run

The workspace skill told the model to put the widget data shape and a
source marker in a trigger prompt. Some proposals then asked the run to
print that JSON, and every run ended its chat with a stray line of it.

The skill now says source and note live inside the data file and are
never the answer, and that a prompt must not ask for JSON. The runner
appends one closing instruction to the first message of every trigger
run: finish with one short plain sentence. The propose_trigger and
update_trigger descriptions say the prompt must stand alone and must
not ask for JSON. Connector chats are talks with people and do not get
the line.

* Read the images of a page as base64 for its frame

The bridge of a page reads UTF-8 text only, so the UI could not put a
png or a jpg of the page's folder into the page. A read of the page
file routes with encoding=base64 now returns an image as base64 with
its media type. Only the extensions of an image are read this way
(png, jpg, gif, webp, avif, bmp, ico, svg); any other file is 415, so
this is no way to read an arbitrary binary file. The path checks, the
1 MiB limit, the viewer's rights and, for a shared page, the consent
check are the same as for a text read.

Assisted-by: Claude:claude-opus-5-5

* Let a page use the files next to it

A page runs from a srcdoc with no network, so fetch('news.json'),
<script src="app.js">, <link rel="stylesheet" href="style.css">,
<img src="logo.png"> and import './x.js' all failed without a word.
Models that split a page into files, or load its data with fetch,
made pages that showed nothing.

Before the frame loads, the UI now reads the files that the page names
with relative URLs, with the same calls as the bridge, and puts them in:
classic scripts in place (deferred ones at the end of the body), style
sheets as <style> with their @import and url(), images as data: URLs,
and ES modules as blob: URLs behind an import map, so cycles and
import() work. A page with modules gets blob: in script-src; no other
part of the policy changes. Inside the frame, fetch and XMLHttpRequest
read relative URLs with files.read and answer with a real Response (200,
404 for a missing file, 413, 415); any other URL rejects with "network
is off in pages; put the data in a file next to the page".

Every path is resolved inside the page's folder: .., %2e%2e, absolute
paths, backslashes and protocol-relative URLs are refused, and the
query and the fragment are dropped. The files go in only after a shared
page is allowed, with the viewer's rights. The files that go in are at
most 4 MiB, images 2 MiB; a script or style sheet that does not load
shows a notice in the page. A change of one of these files reloads the
page, as a change of index.html does.

The skills, the docs and the shared pages fixture say and test the same.

* Return tool descriptions from an MCP connector test

A connection test listed only the tool names. A person who adds a
server cannot tell from a name such as "query" what the tool does or
whether to keep the connector on.

The test response now also has tool_details: each tool with the
description its server gives, in the order of tools. tools is
unchanged, so existing clients keep working.

Assisted-by: Claude:claude-opus-5-5

* Add jq, ripgrep, sqlite3 and archive tools to the Sandbox guest

The guest user cannot install packages and apt is blocked by the proxy,
so any tool the model needs has to be in the image. Add jq, ripgrep,
sqlite3, zip, unzip, file and tree to the final stage.

A new check-tools.sh runs in the existing build step and fails the build
when one of these programs, Poppler, git or curl is missing or does not
start.

The list is one constant, GuestTools, in the shared sandbox package. The
Commands block of the prompt of an isolated chat names it. The tool
description (capped at 400 characters, already full) and the turn note
(cut at 400 characters) have no room for it. Tests keep the Dockerfile,
the check script and the Sandbox documentation in line with the constant.

Assisted-by: Claude:claude-sonnet-5-5

* Keep the helper files of a chat in its work folder

A chat asked for a Word document left a 19 KB build script at the top of
the user's home, next to the user's own files. Chats like it leave
scripts, intermediate data, logs and drafts at the top level or in
folders such as scripts/, and nothing tells them apart from what the
user asked for.

Each chat now has a work folder, Chats/<chat folder>/work/ in the
user's home, next to its attachments. The chat takes the name of its
folder at its first turn (checked against the folders and the other
recent chats of the user, so two chats with one title get two names)
and makes the folder only when it is used: before a bash command runs,
or when a file is saved there. The prompt of every turn names the
folder and says what goes in it: scripts, helper code, intermediate
data, logs and drafts go there; the deliverable goes where the user
said or at the top of the home; no new top-level folders for scripts;
a run-once command needs no file. A sub-agent is told its parent's
folder. The descriptions of bash (the Sandbox's, within its 400
characters, and the built-in one) and of write_file end with one short
hint, and the built-in office, apps and workspace skills say the same
in one line.

The steering is soft. When write_file, move_file or a command leaves a
helper file outside the work folder, the result gets one line that
suggests moving it, at most once a turn of a chat.

One function (workspace/workfiles) decides the kind of a file:
working for anything in a chat's work folder, or for a script, a log
or a temporary file by its extension or a folder named scripts, tmp or
scratch; deliverable for everything else, and always for pages, the
LocalAI folder, the shared folders and the files the user attached.
The chat's file list (kind), the files of a command's card
(files[].kind) and the card of a file tool (file_kind) carry it, so the
interface only renders it.

The runtime setting chats_work_folder (on by default) turns the
steering off.

* Stop telling the model that the Sandbox has npm

does not exist.

* Open the links of a page after the person confirms them

A page runs in a frame without allow-popups or top navigation, so a
click on <a href="https://..."> did nothing, and a link to #id loaded
LocalAI's own address in the frame, since a srcdoc resolves it against
the parent. A news page had only dead links.

The bridge of the frame now takes the clicks on links (also with a
modifier, the middle button or Enter) and window.open(), and sends
link.open(url) to the host. The host lets through only an http or https
address without a user name or password, at most 2048 characters;
javascript:, data:, file:, blob:, //host and links to other files of
the page are refused with a message in the console. A bar above the
page shows the site in large type, the whole address, and Open and
Cancel. A host in punycode also says how it reads, since it may imitate
another site. Open is a click in the app, so the new tab is not blocked
and opens with noopener and noreferrer. A page asks at most 5 links at
once, then one every 3 seconds. A link to #id scrolls the page.

The sandbox, the policy of the frame and the consent of shared pages do
not change; a shared page asks the same way.

* Let the items of a Home widget link

A list widget showed each item as plain text, so a digest of articles
or a list of pages could not take the person anywhere. An item now has
an optional url. An http or https address without a user name opens in
a new tab with noopener and noreferrer, and its tooltip names the site;
a path of the app (/app/pages, /app/chats, /app/files and the other
screens a person reads) opens inside LocalAI. The label is the link,
with a focus ring, an underline on hover and focus, and an icon for an
address outside the app.

The widget-data schema checks the url, and the server adds an error in
words that names the item and the rule, so a trigger run that writes a
bad link learns why. The skill and the docs show the field.

Assisted-by: Claude:claude-opus-5-5

* Attach any file in a chat with one button

The chat had three attach buttons (image, audio, file) that all add to
the same list, and the file button's dialog filtered on */*, which
some file dialogs read as a type filter that greys out archives such as
.zip. A chat now shows one Attach file button whose dialog has no type
filter. Composers without anyFile keep the three buttons.

* Accept both Node behaviours for a broken punycode label in the link test

Node 22 refuses the address, Node 24 parses it. Both mean the page never
opens it unwarned.

* Show a chat's working files apart from what it made

The Files pane, the steps and the preview treated a helper script like
the document the user asked for: a 19 KB build script was listed next
to the document, got a chip under the answer, and the preview opened on
whichever file was newest.

The interface now renders the kind the server puts on each file. The
pane lists what the chat made first and folds the working files into
one quiet heading under the rest, "Working files · 2", with a line that
says what they are; opening it shows their rows, which preview like any
file. A working file opened from a step unfolds the group. The preview
that opens by itself after a turn picks the newest file that is not a
working file, and the chips under the answer name only those files. A
step that saved working files lists them as one line, "Also saved 2
working files", that opens to their chips, and the file of a write_file
step that is a working file is a quieter chip. The files the user
attached are unchanged.

* Add a search field and a segmented filter to the UI kit

The Agents views each drew their own toolbar: a search box capped at
320 px on the agents list, round chip filters on the triggers history,
and a bare checkbox on the tasks page. Add-ons already had the look the
product wants (a search that fills the row and a segmented tray), but
only as add-on classes.

SearchField and Segmented are that toolbar as two small primitives with
ui-* classes and token values only. Segmented buttons carry their id in
data-filter, so specs can press them. The README shows how to use them.

* Draw an agent task run as a history row with its output

The jobs of an agent task were table rows that opened to bare <pre>
blocks: no copy, parameters printed as k=v, the traces in a raw
<details>, and "by manual" in the server's words.

RunItem is one run of a history list: a toggle, the state chip, what it
was and what happened, when and for how long, small actions, and the
details that open under it. OutputBlock draws an answer or an error in
mono with a Copy button. JobRow and JobDetail use them for a job: the
values it ran with as labelled chips, the answer or error, the steps,
the webhook outcome and a link to the chat that holds the run. Times
show as words with the full date as a tooltip.

The agent task helpers gain the pure rules the page needs: the jobs of
a task, the run filters (waiting and running count as in progress), the
on/off filter and search of the task list, the field errors of a save,
how a job started, and the API call that runs a task by name.

* Create, edit and run agent tasks in a side sheet

The task form opened as bare fields above the list, with a checkbox for
On and a Save button that was only disabled when a field was missing.
Run with parameters was a second inline form in the same place.

TaskSheet is a side sheet with three labelled groups (about, who runs
it, what it does), help under each field, the parameters the prompt
asks for as chips while you type, and an On switch. Save checks the
required fields, says next to each one what is missing, and moves the
focus to the first. RunSheet asks for each value the prompt names and
shows the prompt as the task will receive it.

* Show the details of an agent task in a pane with tabs

A task had no details view: its prompt, its runs and the way to run it
over the API were only in the lede of the page.

TaskPane is the kit's side pane with three tabs. Overview shows who
runs the task, the values it asks for, the prompt and a curl call that
runs it by name, with Copy. Runs lists its jobs. Settings holds the On
switch, the webhook count and Delete. Run and Edit stay in the footer.
The tabs move with the arrow keys, Home and End.

* Rebuild the agent tasks page from the shared list pieces

The tasks page looked unstyled next to Add-ons and the agents list: two
raw tables under uppercase eyebrows, a bare checkbox for All users,
forms that opened above the list, three text buttons on every row, and
on a phone a table that broke names one syllable per line.

The page now uses the same pieces as the polished pages. The header has
one line and New task. A toolbar holds the search, an All/On/Off filter
and, for an administrator, an All users switch. Each task is an agent
row: a tile, the name, two lines of description, who runs it and what
it asks for, the last run's state and time with the run strip, an On
switch, Run and a menu. A task with no parameters runs at once. The
name opens the details pane; New task, Edit and Run open the sheets.
The run history is grouped by day, with a state filter, a task filter
and Show more. A job is deleted after an in-page question. With no
tasks the page explains what one is, with an example; a failed load
shows the error with Try again. On a phone the controls grow to 44 px
and the filters scroll sideways.

New strings, and the task strings that existed only in English, are in
all nine locales; the strings the page no longer uses are gone. A new
stubbed spec covers the list, filters, sheets, pane and history, and the
real-server spec follows the new controls. The docs describe the page.

* Rebuild the MCP connectors page on the Add-ons patterns

The page read as a form: every connector was a row of raw controls (a
checkbox, a Test button, red Delete text), the add form pushed the list
down, a test result vanished on reload, and the frame was narrower than
the pages next to it in the sidebar.

The page now uses the same blocks as Add-ons and Files:

- Full page width and the shared PageHeader with a one-sentence purpose
  and "Add connector".
- The Add-ons toolbar (search and a state filter with counts) from four
  connectors, and the Add-ons rows: a monogram tile, a state chip
  (Connected, Needs sign-in, Can't connect, Not tested, Off), one line
  with the tools or the reason, a meta line, the kit Switch and a menu.
- Details in the shared SidePane: the switch, the last test, the tools
  with their descriptions and a search, the connection with the query of
  the address hidden, and what is saved.
- Add and edit in the shared SideSheet: kind first, grouped fields with
  inline checks, masked secrets with show and hide, then "Save and
  test", the result with the tools, and Turn on. Escape and Cancel ask
  before they drop typed changes.
- An empty state that says what a connector is for.

The last test of each connector is kept in this browser with a hash of
what it tested, never the address or a secret, so the page shows the
last known state after a reload. Strings are in all nine locales.

* Document the MCP connectors page and its states

The MCP servers section now describes the add sheet (kind, checks,
masked secrets, Save and test, Turn on), the states a connector shows,

* Render a preloaded page without its loading placeholder

A page that was preloaded still showed the route's loading placeholder
when it opened: React.lazy suspends once on its first render even when
the chunk is already in memory, and React keeps a fallback on screen
for at least 300 ms once it shows one. Opening a chat from Home showed
a blank page for that time.

The page loader now remembers the module once it has loaded and hands
it to React.lazy as a thenable that resolves at once, so a preloaded
page renders in the same commit. A preload of a segment now warms
every page registered under it: /app/chats is the chat page, its
connectors and its conversion page, and before only the last one
registered was preloaded.

* Move the composer from Home into the new chat in one gesture

Sending the first message on Home was a hard cut. The page stood still
while the chat was created, then showed a blank placeholder, the empty
"new chat" screen with its composer in the middle, an empty thread
with the composer at the bottom, and only then the message, while the
sidebar folded and moved the whole column. Focus was lost.

Now Send fades the rest of Home and keeps the composer in place while
the message goes. When the send has answered, a view transition moves
the composer to the dock of the chat, lifts the text out of it into
the message, moves the attached files with it and folds the sidebar in
place; the model's indicator comes in after the message has landed and
the empty composer has the focus. The chat page draws the message from
what Home already knows (a small hand-off store: the chat record, the
text and the files, with the local copy of an image for its thumbnail)
and keeps the same row when the server's transcript replaces it, so
nothing is drawn twice or animates again. What is sent to the server
does not change.

A browser without view transitions gets a FLIP slide of the composer
and the message (Web Animations, transform and opacity only). Less
motion gets a short cross-fade, or an instant switch. A send that fails
brings Home back, shakes the composer and keeps the draft; a second
Enter while one send is in flight sends nothing. The draft is cleared
when Home closes, so the box never shows its placeholder on the way.

Focus mode folds the sidebar in a layout effect, so the fold happens in
the frame the conversation appears. One motion token is added,
--dur-glide (360 ms), for a part that travels to its place on the next
page.

* Draw the triggers as rows and their history like the task runs

The triggers page used a table with a switch column next to the agents
card list, folded its list behind Hide, filtered the history with round
chips, and on a phone cut each history row at the right edge.

Each trigger is now an agent row: a clock or folder tile, the name, the
schedule in the server's words, the agent or model and when it runs
next, the last run's state and time with the run strip, an On switch,
Run now and a menu. The week sentence sits under the Run history title.
The history uses the segmented filter and the same run rows and day
headings as the agent tasks, with Show more after 30 runs; an open run
shows its reason with Copy. On a trigger page the prompt comes before
the runs, in the body face, the On switch is the kit switch, and the
runs stop at 10 with Show more.

* Use the shared search and the full width on the agents list

The agents list stopped its search at 320 px and used the content width,
while the Triggers and Tasks views next to it use the full width, so the
title and the view tabs moved when you switched views.

The list now uses SearchField, which fills the toolbar row as on
Add-ons, and the full page width like its sibling views.

* Polish the agent task sheets and pane after a visual review

Screenshots of every state showed a few rough edges:

- The name placeholder looked like a filled-in value next to the error
  "Give the task a name". The name field has no placeholder now, and
  the prompt placeholder starts with "For example:".
- A task run by an agent showed the agent id until the agents were
  read. It says "Agent" until then.
- A run opened in the details pane also opened in the history, and the
  two copies shared an element id. The pane keeps its own open runs and
  ids.
- A failed run in the pane drew its meta line in red; the title carries
  the error colour there now.
- A group title that is not a legend had a double gap under it, and the
  kebab menus were under 44 px on a phone.

* Cover the code files of a shared page in its consent

The consent to a shared page was kept against the hash of index.html
and page.json. The UI also puts the scripts, style sheets and modules
next to the page into it before it runs, so the author could change
app.js after a viewer allowed the page and run new code without asking
again.

The server now finds the same files as the UI's inliner: every script
src, stylesheet link, relative CSS @import and module import of the
folder, followed through the module graph. Their content hashes go into
the hash of the page, and a file the page names that is missing counts
too, so adding it later also asks again. Data files and images stay
out, so saving data does not ask again. The files are listed as
code_files. What a file names is kept per content hash in a small
per-frontend cache, which only saves reads.

Two more checks close the gaps around it. A frame of an older version
that reads a changed file of code gets 409, so a script edited while
the page is open never runs under the old consent. The UI puts no text
file into a shared page that is not in code_files, so if the server and
the UI ever disagree, the file fails to load instead of running outside
the consent. The trust sheet names the files of code when only one of
them changed.

* Let a page be a tile on Home in its compact mode

Home widgets could show a list, a number or the last chats, but not one
of the pages a person or the assistant built. A page can now be a tile.

A page opts in with a widget block in page.json: a size (small, medium
or large, the height of the tile) and an optional short title. A
widget of type page in LocalAI/home.json names the page, and a folder
id for a page of a shared folder. The server takes at most three page
widgets and says why in words, and refuses a name that is not a page
name.

The tile runs the page in the same sandbox and bridge as the full
view. The page reads localai.page.mode ("widget" in a tile, "page"
otherwise) and localai.page.size, and <html> carries data-mode and
data-size, so the page decides how its tile looks instead of being
shrunk. The tile reserves the height of its size, builds its frame only
once it scrolls into view, tells the page through a new visibility
event when it goes out of sight or the tab is hidden, takes the frame
down far off screen, and keeps at most three frames alive. It has a
title bar with Open page and a refresh button, a skeleton while it
loads, Retry on an error, and the link question of the full view. A
page that is gone or has no widget block shows a calm line with a link
to Customise Home; a shared page that the viewer has not allowed shows
Allow this page, which opens the same trust sheet.

Customise Home lists the pages with a widget block, with the size of
their tile. The task board starter has a compact view, the skills tell
the assistant how to put a page on Home, and the docs describe it.

* Give the Files upload its own size limit

The Files page upload was capped by the general --upload-limit (15 MB
by default), although a workspace file can be 256 MiB.

Make 0 the default of --upload-limit, meaning not set. When it is not
set, the general routes keep the 15 MB limit and the Files upload route
skips it, so the workspace file size is its limit. When the operator
sets a value, it applies to the Files upload too, lower or higher (a
file never exceeds the workspace size). The max_file_size of a folder
listing reports the limit in force.

* Refuse writes of code files from a page

A page loads its own scripts, modules and styles, so a page that could
overwrite app.js or style.css would run new code on its next load. The
page bridge now writes data files only.

The server refuses a write whose final segment has a code or document
extension (js, mjs, cjs, css, html, htm, svg, xml, xhtml, wasm), is named
index, or is page.json, with 403 and a clear message. The check applies
to the page routes only; the Files page and the assistant's file tools
keep full write access. The judgement lives in pages.IsCodeFile and is
mirrored by isCodeFile in the web host, which refuses early with the
error code forbidden. Both run one table of cases, covering case, double
extensions, trailing dots and spaces, percent-encoding, backslashes and
lookalike dots.

* Make the trigger tools a built-in group a chat can switch off

propose_trigger, list_triggers, update_trigger and delete_trigger were
added to every chat a person starts, with no switch. They are now four
entries of the built-in tool registry in one group, triggers, so the
Tools menu, the tools panel, the draft list and the builtins switch
endpoint handle them like the web group. The group is on by default.

A trigger or connector run and a sub-agent still never get them. The
panel lists the group as not usable, with a reason, for those chats,
for a user without the triggers feature, and not at all when the server
runs no triggers. The group has no runtime setting, so the registry
gets an Unlisted flag and Settings > Tools skips it. The panel now
builds every grouped tool to learn whether it is usable, not only the
opt-in ones.

Assisted-by: Claude:claude-sonnet-5-5

* Show the Triggers group in the chat Tools menu

The menu rows come from the groups the server lists, so the row needs
only its label in the nine locales. A Playwright spec covers the row,
its switch request, Select all and Disable all, and the disabled row
with its reason.

Assisted-by: Claude:claude-sonnet-5-5

* Talk about settings, not the files behind them

The settings cards, the shortcuts row, Home and the change notes in a
chat named the files that hold a person's settings: "Defined in
LocalAI/shortcuts.json", "Layout is in LocalAI/home.json", "Saved
LocalAI/persona.json". A person changes their shortcuts or their Home,
not a file, and the Files page still shows the files to whoever looks.

The "Stored in", "Defined in" and "Layout is in" lines are gone; the
history line keeps Versions, Revert and the Invalid badge. The notes
say what changed ("Saved your shortcuts.", "Created the page Task
board."), the errors name the setting or the widget instead of a path,
and the Source view says "The settings as text" instead of JSON and
schema. A failed save now says what happened in one plain sentence and
keeps the server's own words under a collapsed Details. The drafts that
"Edit with the assistant" puts in the composer no longer carry the
path; the built-in workspace skill already maps shortcuts and Home to
their files.

All nine locales are translated; only the changed keys moved, and four
keys that nothing reads any more are removed.

* Drop internal names from the skills, add-ons and tasks copy

Other pages used words that only make sense to someone who knows how
LocalAI is built:

- Skills said "a folder with a SKILL.md" and "the file workspace". It
  now says what a skill is for, and that skills need Files.
- The add-on notes blamed "the owner", the internal name of the server
  that runs add-ons. They now say what happened to the action, or that
  the add-on service is not available; a private library names a
  credential "an administrator configured on this server".
- The Tasks header listed an API route, and the first-run wizard spoke
  of a "host bash fallback". The memory line of Settings no longer
  mentions "the resources endpoint".

All locales that have these keys are translated. The skill delete
dialog, the unused skills intro and the Tasks header exist only in
English and change only there.

* Fail the unit tests when UI copy names implementation details

A new test reads every string of every locale and fails when one names
a settings or data file (.json, .yaml, LocalAI/), an API route or HTTP
method, a setting key (chats_*), an environment variable, a format
word (JSON, YAML, schema) or a path shown as code. Plain words such as
"schema" and "endpoint" are checked in English only, since other
languages use them for other things.

Operator pages may still name the model configuration, the metrics
route or a startup setting that the docs name. Those keys are listed in
ui-copy-allowlist.json, each with the audience and the reason. The list
only shrinks: an entry whose string no longer needs it, or whose key is
gone, fails too.

* Name the triggers group in the chat tools routes

The routes that list and switch the built-in groups of a chat said only
"a name such as web". They now name all three: web, triggers and
saved_agents, with the tools of each.

* Make the built-in skills answer in plain words

The skills told the model to report file names, folders and formats
after a change. Add one rule near the top of localai-workspace and
localai-apps: do the work with files, but say what changed, and name a
file only when the user did or asks. Replace the example replies that
carried paths, keep every path that says where to write, and pin the
rule with a test.

* Apply the Go 1.26 modernizers to the latest Studio code

go fix suggested slices.Contains, strings.SplitSeq and range-over-int

hand-written membership loop, so it uses slices.Contains too. Only
lines that the branch added since then are changed.

* Share the blob wait and the counting of the two workspace purges

The JSON and GORM stores each had the 2-minute default for the blob
grace, the same switch that reads the BlobGrace option, and the same
loop that counts files, folders and bytes per revision. They now call
blob.Grace and PurgeResult.Add, both with specs. The SQL and the
in-memory walk that pick the nodes stay in each store.

* Read the upper layer of a sandbox in one place for both stores

The JSON and GORM workspace stores had the same readUpper, place,
joinRel, depth and sortedKeys, with the same upperSet types. They move
to workspace/internal/upperset, which has its own specs. The commit
algorithm that applies the set to the nodes stays in each store; it
needs a storage interface first.

* Let chat attachments use the 1 GiB message limit

The docs promise 1 GiB for a message with attachments, but the general
body limit (15 MB by default) ran first, because only the Files upload
skipped it. Skip it also for a multipart POST to the messages route
when the operator set no --upload-limit. A JSON message keeps the
general limit, and an explicit --upload-limit still wins. A message
that goes over the 1 GiB limit now gets 413, not 400.

* Name the read_file tool in the skills index header

A weaker model read a built-in skill with the wrong path and then tried
the Sandbox, which cannot see skill folders. The header now says which
tool reads a skill and that the shown path is the one to use, before it
mentions where the user's own skills go.

Assisted-by: Claude:claude-sonnet-5-5

* Tell the model that skill folders are not in the Sandbox

The Commands block of an isolated chat now says that skills are read
with read_file. The Sandbox tool description and the per-turn note are
at their size caps, so the sentence goes in the system prompt.

* Point read_document at read_file for text files

read_document reads PDF, Word, Excel, PowerPoint and EPUB files. For a
Markdown or text file it said only that the file is not a document it
can read. The error now names read_file.

* Tidy the text index stores and the indexer pool

The two stores wrote the default limits 20 and 100 as numbers in five
places; they are now named constants, so the stores cannot drift. The
JSON store checks a missing file with errors.Is. The indexer starts its
readers with wg.Go and keeps the first error inline, which drops the
cmpErr helper.

* Refuse the server's public address in the Sandbox proxy

web_fetch refuses the addresses of the server: its interfaces,
loopback and the host of the external base URL. The Sandbox proxy runs
in the add-on process and listed only the interfaces of its own
machine. Under "All public sites", an always-allowed host or an Allow
card, a command could reach the LocalAI API through the public name or
address of the server, a NAT address or a proxy in front of it.

The host now keeps one list for both. The application builds it once,
gives it to web_fetch, and sends it as CIDR strings in the new self
field of every egress.check allow. The proxy keeps the last list it
got and refuses it on each dial, besides its own interfaces, also for
an allow it cached. safehttp gets the codec and a join of deny lists,
so both sides read the list the same way.

* Check the TLS server name on every port of the Sandbox proxy

The proxy checked the ClientHello only on CONNECT to port 443. An
always-allowed host pinned to another port, or any port added to
chats_egress_ports, was a raw tunnel: a command could open TLS to
another tenant of the same front through it. The docs said the server
name must still match.

On other ports the proxy still waits for nothing, since the protocol
may be anything and the server may speak first. But when the first
bytes from the guest are a TLS handshake record, it reads the whole
ClientHello and passes it on only when the server name is the CONNECT
host; otherwise it closes the tunnel and audits the reason sni.

* Say what sent each notification

The inbox only knew whether a notification was about a run or needed
attention, so a trigger that was switched off and a connector that was
switched off looked the same. Each notification now carries a source:
trigger, connector or system (the conversion of old data). The list
endpoint returns it, and items stored before have none.

* Say where a skill is when a read of it fails

When read_file, read_document or list_files fail with not found for a
path that names a skill of the chat (a wrong skills folder, or just
<name>/SKILL.md), the error now gives the skill's real path and says to
read it with read_file. The skills come from the chat's own resolver, so
every layer, add-on and per-user switch is respected, and nothing is
looked up unless a read fails.

Assisted-by: Claude:claude-sonnet-5-5

* Keep the last valid Sandbox network lists when a value is bad

The settings endpoint refuses a bad chats_egress_allowed_hosts with the
reason, and the runtime settings file keeps the value in force. A bad
value that reached the configuration another way was dropped with no
log line: the always-allowed hosts and the extra registries became
empty, and a bad port list fell back to 80 and 443, which can widen a
narrower list.

Each of the three lists now keeps the last value that parsed, logs a
bad value once, and uses the default only when the process never saw
a valid one. The parse runs again only when the value changes, not on
every egress.check.

* Use the keyless chain of the built-in search in the Web add-on

The add-on replaces the built-in web_search, but its keyless provider
was DuckDuckGo alone. DuckDuckGo often answers data-center addresses
with a bot check, so installing the add-on without a key made search
worse than the built-in, which falls back to the Brave Search and Bing
result pages.

The keyless entry of the add-on's order (saved name duckduckgo) is now
the built-in chain from pkg/web/search: DuckDuckGo, then the Brave
Search page, then the Bing page, with the same cool-down. The status
tool reports the providers in their cool-down, and the Settings tab
shows them with the reason. Test the providers gives one row for each
page of the chain.

* Fix the GitHub hosts in the Q1 row of the egress design

The Q1 row still listed raw.githubusercontent.com on the registries
list. The owner decision below it and registries.json exclude it,
since it serves any user content, and add
release-assets.githubusercontent.com. The row now says the same.

* Keep one private-address rule for the network cards

A card asked whether its host is a private IP literal by calling
egress.Admits with a made-up ceiling, which re-derived the rule that
egress already has. egress.PrivateLiteral is now exported (with a spec)
and the card uses it. The two String methods of an allowed host write
host:port with net.JoinHostPort, which brackets an IPv6 literal the
same way the hand-written code did.

* Read a unique constraint violation in one place

The jobs and triggers stores had the same isUniqueViolation, and the
saved agents store had the same test inline before it looked for the
name index. They now call dberr.IsUniqueViolation, which has specs for
the SQLite and PostgreSQL error texts. The workspace store keeps its
own stricter match.

* Ask before a Home widget link opens another site

A list widget turned an http or https item into a plain link to a new
tab. Its data file is written by trigger runs and the assistant, which
read web text, so a planted link opened with one click, and only a
tooltip showed the host. A link of a page asks first.

An external item link now opens the confirmation bar of page links in
the widget: the site, the full address, the punycode warning, and Open
or Cancel. A link inside the app still navigates directly. The bar
takes a label, so the widget says that it wants to open the link.

* Prune the audit of the commands run on this machine

The audit of the built-in bash had no retention: the database table
grew without bound in a cluster, with commands of up to 4 KiB each.
The Sandbox network audit had chats_egress_audit_days and a daily
prune under an advisory lock.

Both audits record what the commands of the chats did, so the host
command audit now uses the same retention and is pruned in the same
daily pass: one frontend of a cluster, under the same lock; a
standalone process alone. The GORM and file stores get Prune. No new
setting.

* Save the Studio JSON stores with atomicfile.WriteJSON

Seven stores (agents, connectors, jobs, MCP connections, notifications,
push subscriptions and triggers) encoded their state and then called
atomicfile.Write with the same four lines. atomicfile.WriteJSON does
both and has specs. The load side stays in each store, since the error
messages differ.

* Build the result page walkers of the keyless search on one walk

hasChallenge and firstByClass each had their own recursive walk that

* Expire network cards that a dead frontend left pending

Pending network cards expired only on the turn-end path of the process
that ran the turn. When that frontend died, its cards stayed pending
in the chat record, counted toward the cap of three, and gave the next
turn's connections cards-full blocks. The UI showed them as waiting.

A card now names the turn that asked it. One rule, shared with the
command card in a later change, says whether a card still has a
waiter: its turn holds the chat and its wait has not run out. A card
that fails it reads as expired, takes no place under the cap, and is
expired in the record when the next card is asked, when the next turn
starts, or when the reaper ends the dead turn.

* Reuse ChooseProvider for the expected add-on of a tool

shadowers.expected repeated ChooseProvider line for line: the pinned
add-on when it is installed, else the oldest install. It now calls it.
commandFiles kept an order field and sorted the nodes of a map by it;
it now appends each node to a list when it first sees it, which gives
the same order without the sort.

* Do not print a nil error when a key or entry is missing

Three checks joined "the read failed" and "the read found nothing" in
one branch, so the second case wrote "<nil>" into the message: the
VAPID keys of push notifications, the sealing key of connectors and a
rendered catalog entry. Each case now has its own message. The message
of a failed read does not change.

* Check the close errors and rename the tool variables

golangci-lint failed on the new studio code. Five deferred Close calls

explicitly and name the locals tool.

* Make the file text index forget purged files and say its limits

Three gaps of the text index of documents:

- A purge dropped the index entries of what it erased in a goroutine
  that only logged its errors, and the purge had already erased the
  journal rows. A crash or a store error left the text in the database
  for good. Each pass of the indexer now also checks a batch of entries
  (200 every 30 s, round all of them) and deletes those whose node is
  gone, so what a failed Forget leaves is removed.

- A document search stopped at 20000 files or 64 MiB of text without a
  word, and the "still being indexed" count stopped at 50. The search
  now sets Limited (search_files says "results limited", the REST
  answer has "limited", the Files page shows a note), and the count is
  the number of pending entries below the path.

- read_file extracted a long document again for every page, up to 50
  MiB and 60 s each time. The first read keeps the whole text in the
  index store by content hash (a new documents table, or files in the
  JSON store), and the next pages come from it. The text goes away with
  the last entry of that content, on delete and on purge.

Search reads the text without its folded copy, which only the database
needs.

* Stop the PDF reader when the extraction gives up

The PDF and EPUB reader runs in a goroutine, and the call returns after
60 seconds when it is slow. The goroutine went on reading every page,
since its context ended only with the caller's. It now gets a context
that ends when the call returns, so it stops at the next page. What
the call returns does not change.

* Compare the code files of a shared page as the store does

The guard that refuses new code to a frame of an older version compared
the name it reads with the names of the page's code exactly. The
workspace folds case, so an old frame that read Index.html or JS/App.js
got the new code with no 409. Compare names in the store's form
(workspace.FoldName), as the write check already does, and test the
case variants.

* Expire the command card of a turn that is over

The card of the built-in bash was cleared only by a defer in the call
that asked. When that frontend died, the card stayed in the chat
record. The chat hid it only while no turn ran, so the next turn
showed it again, and an answer to it reached no one but still got 204.

The card now names its turn and when it was asked, and follows the
same rule as the network cards: it waits only while that turn holds
the chat and its five minutes have not run out. GET /api/chats/{id}
shows only such a card. The next turn and the reaper clear a card left
behind, and the waiting call clears only its own card, so it never
removes a newer one. An answer to a card with nobody waiting is
410 consent_expired, and the chat shows the card as not answered, with
no buttons. The store gets UpdateHostConsent, an atomic change of the
card.

* Answer a trigger change once across frontends

ApplyChange, UndoChange and DismissChange checked the outcome of the
change record under a mutex of one process, then wrote the store. Two
frontends could both see a pending change and both apply it, or both
undo it.

Add Store.SetOutcome, a conditional update of the outcome (only from
the outcome it names), to the GORM and JSON stores and to the store
suite. The three answers now claim the record with it before they
write, give the outcome back when the change itself fails, and answer
ErrProposalAnswered (409) when another request won. A test runs the
two answers on two frontends at the moment between the read and the
write, for an edit, its undo, and a delete.

* Give the chat settings without an assistant tool their reason

chats_max_iterations, chats_work_folder, chats_index_files and

adminRoutesWithoutTool, and the older chats_saved_agents,
chats_suggestions, chats_vision_model and chats_transcription_model

in Settings: they apply to every user's chats, and the step limit is

* Bring three design specs in line with what shipped

- web tools and shadowing: the status still said phase 2 waits; both
  phases shipped. Note that the Web add-on's keyless entry is now the
  built-in keyless chain.
- Home front door: Home now creates the chat and sends the first
  message itself, with a short-lived hand-off to the chat page, and
  its composer takes attachments. Both were described the old way or
  as out of scope.
- chat footer: the meter bar is 96 px with the tokens left, and a phone
  keeps the bar and the tokens left, not the percentage only.

* Store the command card's answer and read it back every two seconds

The answer to the command card of the built-in bash went only as a
bus message. When the message was lost, the call waited the full five
minutes and ended as not answered, although the person had clicked.
The network card stores its answer first and re-reads the card every
two seconds.

The command card now does the same, through one shared pair of
helpers: listenConsent subscribes before the card is stored, and
waitConsent wakes on the bus message or every two seconds and reads
the record, which holds the truth. The network card uses the same
helpers. HostExecDecide writes the decision to the card atomically
before it sends the message: the same answer twice is 204, the other
answer 409 already_answered, and an answered card is no longer shown
as waiting.

* Load skills by name with a load_skill tool

A weaker model failed to read a skill at the path the index showed. The
chat now has a built-in load_skill tool that takes a skill's name and
returns the instructions of its SKILL.md, without the frontmatter.

The tool reads the same resolved skill set as the index: the nearest
skill of each name, the chat's switches, the add-ons the chat can use
now and the grants of its agent. It reads through the user's rights.
When the skill's folder holds other files, the answer starts with the
base directory and names up to 20 of them for read_file; a chat without
read_file gets the instructions only. A skill that needs commands, in a
chat that cannot run them, is refused with the reason. An unknown name
is an error that gives near names first and then every name the chat
has.

Every chat with at least one skill gets the tool, and a sub-agent gets
it with its parent's tools. It has no switch and Settings > Tools does
not list it.

The index of skills now lists names and descriptions only and tells the
model to call load_skill. The Sandbox sentence and the error for a
wrong skill path now point at load_skill too.

* Tell the built-in skills to load other skills by name

localai-apps told the model to read the localai-workspace skill, and
writing-skills said a description is what the agent sees before it
opens the file. Both now speak of loading a skill with load_skill.
localai-workspace keeps the path of its schemas folder and says to read
it with read_file, since those files are not a skill.

A test checks that no built-in skill sends the model to another skill by
"read" or by the path of its SKILL.md.

Assisted-by: Claude:claude-opus-5-5

* Document load_skill and the skills index

The chats page now says that the prompt lists skills by name and
description, that load_skill returns a skill's instructions and names
the files of its folder, what it refuses and who gets it. It no longer
says the model reads a skill by its path. The add-ons page says how a
chat loads an add-on's skill, and the saved agents page says that the
skills grant limits load_skill too.

* Add the proposal action spec to the tables-acceptance inventory

The spec that an editor cannot confirm a schema change as a write ran in
the suite but was never in the inventory, so the evidence manifest check
failed. CI did not reach that check before, because the burst spec
failed first.

* Give a chat a goal that it works toward by itself

A chat can now hold one goal. While it is active, every turn's prompt
names it, the model gets goal_done and goal_blocked, and when a turn
ends by itself the frontend that ran it starts the next one with
"Continue toward the goal". The person's waiting messages still go
first, and a turn they start does not count as an automatic one.

The goal pauses when the person presses Stop, when a turn fails or is
cut short, and when the automatic turns or the model steps reach their
limits. Resume gives it fresh budgets. A sub-agent, and a chat that a
trigger, a connector, a job or a page started, has no goal and no goal
tools.

The goal lives with the chat record in the store (UpdateGoal on the
JSON and GORM stores, with contract tests and a column migration), so
every frontend reads the same one. The next turn goes through the same
turn claim as any other, so only one frontend continues it; a reaped
turn, or a JSON store that reloads after a crash, leaves the goal
paused instead of continued twice. The transcript keeps goal lines
(set, replaced, continue, paused, resumed, done, blocked, cleared) as
their own role, so an automatic message never reads as typed by the
person.

* Add a store for the loops of the chats

A loop repeats a prompt in one chat, at an interval or when the model
asks for the next run. The new loops package keeps the loops, the
daily budget of runs of each owner, and which chats confirmed a loop
once. JSON and GORM stores share one contract suite. Add checks the
limits per chat and per owner in the same step as the insert, and
TakeRun never hands out the last run of a day twice, also across
frontends.

A user message that a loop sent now carries a loop mark (loop ID, run
number, self-paced or not). Both chat stores keep it. The model reads
a short line before the prompt that says the message repeats by
itself, and, for a self-paced loop, how to ask for the next run.

* Check the Settings page and the add-ons with the UI copy guard

The guard read the locale files only. The Settings page keeps its
English labels and descriptions in settingsSchema.js, and several
add-ons carry their own English bundle, so neither was checked.

The guard now also reads the label, description and note of every
setting and the label and hint of every group, and the English
bundles of the add-ons (an en.js module or an English JSON file).
The allow-list takes settings:<key>.<what> and addon:<id>:<key>
entries, each with its reason; the operator ones (the SearXNG JSON
format, the fine-tuning file types, the API route of a voice, the
schema of the Databases add-on) are listed.

What it found in the voice library is fixed in plain words: "model
YAML is not modified" and "Existing model YAML is not changed" now say
that the models' settings are not changed, in the voice add-on, the
Studio add-on and the host locales that have the strings (en, fr,
pt-BR). The two host allow-list entries for them go.

* Draw the Add-ons search and state filter with the kit pieces

The Add-ons page had its own copy of the search box and the segmented
filter (ad-search, ad-seg), the same shapes and styles as the kit's
SearchField and Segmented that the Agents pages use. Use the kit
pieces and drop the copy; the narrow-screen rules now target the kit
classes inside the toolbar. The search keeps its test id.

* Add the limits of a chat goal to the runtime settings

chats_goal_max_turns (1 to 200, default 20) is the most turns a chat
with a goal starts by itself, and chats_goal_max_steps (1 to 10000,
default 400) the most model steps of all the turns of one goal, before
the goal pauses. Both are read when a turn ends, so they apply without
a restart. They sit in Settings > Tools next to the step limit of one
turn, and the settings page documents them.

Assisted-by: Claude:claude-opus-5-5

* Add the goal routes of a chat to the API

GET, PUT and DELETE /api/chats/{id}/goal read, set and clear a chat's
goal, and POST /api/chats/{id}/goal/resume resumes a paused or blocked
one. They belong to the chat's owner like the other chat routes and
take the chats feature. A chat view carries the goal with the limits
that apply now, the transcript gives goal lines with goal_event and
goal_turn, and the event stream has a goal event so that other tabs
read the chat again.

The routes are in the route feature registry, the swagger file and the
chats entry of /api/instructions. They manage the person's own chat,
not the server, so they have no MCP tool, as the other chat routes. The
chats page documents goals, their states and limits, and how several
frontends share them.

* Redesign the notification inbox

The inbox panel was a plain list: every row had the same weight, a
failed run looked like a finished one, the panel ran off the screen on
a phone, and a failed load showed nothing.

The panel now has a header with the unread count, a menu for Clear read
and Clear all, Mark all read, and an All / Unread / Failed filter. Items
are grouped under Today, Yesterday and Earlier. Each item shows what
sent it (trigger, connector or LocalAI) with a tinted icon, the title,
two lines of text or the reason of a failure, and when it happened, with
the exact time on hover. A click marks it read and opens its chat; a
connector that was switched off opens the connectors page. Mark read and
Delete show on hover or focus, and stay in view on a touch screen.

The panel has a loading skeleton, an error with Try again, an empty
state that says what shows up here, and a caught-up state. A new
notification slides in, is highlighted for a few seconds and is
announced once. The badge stops at 99+. Focus moves into the panel when
it opens; the arrow keys, Home, End and Delete work on the items, and
Esc returns focus to the button. On a phone the panel is a sheet over
the bottom of the screen with 44 px targets.

* Explain the reads of the text index and the provider requests to gosec

gosec flagged three new lines. The text index reads files from the
directory the host gave it, with names it listed there. A search
provider sends its request to the endpoint fixed at construction, never
to a URL from a tool call. Mark the lines with the reason.

* Keep the add-on details open when Escape closes a dialog

Escape in the restore dialog of the recovery panel also closed the
details pane around it. The pane handles Escape in React, and the
dialog listens on the document, so the pane ran first and saw no
preventDefault. The pane now registers as a modal layer and closes only
when it is the top layer, as the side panes do.

Assisted-by: Claude:claude-opus-5-5

* Add skill and agent messages, compact and clear to the chats API

A message can now carry a skill of the chat or one of the user's saved
agents. The server checks the name against the chat's resolved skill
set (switches, the agent's grants, shadowing, add-ons) or the saved
agents the chat may call, and refuses an unknown one with a 400 that
lists what the chat has. A skill message gives the model the text of
the skill's SKILL.md before the user's words, for that turn only; an
agent message asks the model to start the agent with spawn_agent. The
transcript keeps the words and the command (Entry.Invoked), not the
instructions. A regenerate or an edit runs the command again. Such a
message does not wait for a running turn: it answers 409.

POST /api/chats/{id}/compact runs the summary the loop makes when the
context fills up, through a new optional session.Compactor that the
loop harness implements with its own history compaction. The compacted
state is saved for the next turn and a "compacted" line with the sizes
goes in the transcript.

POST /api/chats/{id}/clear writes a "cleared" line and drops the saved
state. The model then sees nothing above the line: the rebuilt state
and the transcript summary start after the last such line, so a fork
from above it keeps what the model saw there. Export, import and the
Markdown export carry both lines.

Both calls take the turn claim, so no frontend starts a turn on the
chat meanwhile; messages sent during them start a turn after. No MCP
tool: they act on one chat of the caller and are not admin calls.

* Give each network card spec its own settings

A check that a card spec starts can still wait on its card when the
next spec begins. It read the settings through a closure over a
variable that the next BeforeEach replaced, which the race detector
reported. Each service now reads the settings holder it was built with,
under a lock, and the specs change the settings through it.

* Show the effective audit retention in the settings snapshot

The settings snapshot returned 0 for chats_egress_audit_days while the
setting was unset. Any page that saves the whole snapshot back, such as
the Traces settings strip, then posted 0 and the server rejected it with
"Invalid chats_egress_audit_days", so saving tracing settings failed on a
fresh install.

Report the retention that applies (30 days by default), the same way
chats_max_iterations does.

* Run the Sandbox smoke test in a short scratch folder

The smoke test step was reached for the first time and both isolated
backends refused to start: their state folder under the checkout's
cache made the socket paths 126 and 132 bytes, over the 107 a unix
socket allows. Point SANDBOX_SMOKE_WORK at /tmp/sandbox-smoke, which
leaves room for the sockets.

* Use paths from the home folder in the Sandbox command specs

bash now starts in the user's home folder, so the end-to-end specs that
read and wrote home/<name> found nothing. Use names relative to the
home folder, as the Sandbox specs already do.

* Show the goal of a chat on the chat page

A bar above the composer shows the goal with its state: Pause (which
stops the running turn and so pauses the goal) while it works, Resume
when it paused or needs the person, and Clear. A second line says why
it paused, what the model needs, or what it did. The status line shows
"Goal · turn 3 of 20" while the goal is active, and the Continue button
of a paused turn stays away then, since the next turn starts by itself.

The transcript shows the goal lines as quiet rows: set, replaced,
continuing (with its turn), paused with the reason in plain words,
resumed, reached with the summary, blocked and cleared. A goal event,
also from another tab, reads the chat again, and a hidden live region
says each change to a screen reader once.

The strings are in all nine locales. Unit tests cover the helpers and
the thread rows; a Playwright spec covers the bar, the progress, the
lines, Pause, Resume, Clear and the event.

* Run the loops of the chats

The loop host fires the loops that are due. A run sends the prompt to
the chat as a new message only when the chat is idle: a busy chat
skips the run, and an interval loop moves to its next slot instead of
piling missed runs up. A self-paced loop gets two tools while it is
active: schedule_next (clamped to the minimum interval and one day)
and loop_done. A run in which the model calls neither ends the loop
with a note. A loop ends after its run limit, pauses after three
failed runs in a row, and waits for the next UTC day when the owner's
daily budget of runs is used up.

One frontend fires the loops, the holder of a new advisory lock. A run
is claimed in the store first, and the turn claim keeps one turn per
chat, so a short overlap of two leaders starts no run twice. A new
leader finishes the runs the old one watched. Deleting a chat removes
its loops; a due loop whose chat is gone removes itself.

Five runtime settings bound the loops: chats_loop_min_interval,
chats_loop_max_runs, chats_loop_max_per_chat, chats_loop_max_per_user
and chats_loop_daily_runs.

* Add the loops API of the chats

GET, POST and DELETE /api/chats/{id}/loops list, start and stop the
loops of a chat; PUT and DELETE /api/chats/{id}/loops/{loopId} pause,
resume, confirm or stop one. GET /api/chats/{id} carries the loops,
the transcript marks the user lines a loop sent with loop {id, run},
and a loops event tells every open tab that the list changed.

The routes are gated by the chats feature and documented in the
swagger spec and the API instructions. They act on the caller's own
chats only, so they get no assistant tool. The chats page gets a loop
section, with when to use a loop and when a trigger, and the cluster
behaviour; the runtime settings page lists the five loop settings.

Assisted-by: Claude:claude-opus-5-5

* Show the loops of a chat above the message box

Each loop of the open chat shows as one line over the message box,
such as "Loop · every 5 min · run 4 · next at 09:20", with Pause or
Resume and Stop. A loop that paused itself or ended says why; an
ended one has Dismiss. The first loop of a chat shows a card instead:
"Run this every 5 minutes until you stop it?" with Start and Cancel.
The server keeps the pending loop, so a reload shows the card again.

A message that a loop sent carries a small "Loop run 4" label. The
page reads the loops again on the loops event, so every open tab
follows. The answer to /loop list is ready for the slash command. The
strings are in all nine locales.

Assisted-by: Claude:claude-opus-5-5

* Build the chat slash menu on one command registry

The slash commands of Home and of a chat now come from one registry,
src/utils/slashCommands.js. A command has a kind (navigate, insert or
server), the surfaces that offer it, a needs check and, optionally, an
argument provider: args(query, ctx) returns the items the menu lists
when the box holds "/cmd <query>". Every existing command and test id
stays; the registry adds:

- one command per skill of the chat or the draft (/review), marked
  built-in, add-on, shared or yours, and /skill <name>, which also
  reaches a skill named like a command;
- /agent <name> <task>, which lists the saved agents, or offers to turn
  them on for the chat when they are off;
- /model and /models with a model name, which switch at once;
- /compact and /clear, which show their progress in the status line
  and leave a marker in the thread; the context meter drops;
- /attach and /attach clear, /help (a card that lists the commands)
  and /about (a card with the model, its state, the tools, skills,
  where commands run and the context size).

Tab completes a command or an argument, Enter runs it, and the first
row whose name starts with what was typed is selected first. A message
typed as a skill or agent command is sent with its marker, not as text;
the transcript shows the words and a chip. Home offers the same set
without the commands that need a thread.

The words are in all nine locales. The registry has unit tests, and a
Playwright spec covers the menu, the completion, the marker, the chip,
compact, clear and the cards with the routes stubbed. The docs page
gains a slash commands section.

Assisted-by: Claude:claude-opus-5-5

* Add the /goal command to the chat

/goal shows a card with the goal, its state, the automatic turns and
steps it used out of the limits, and when it was set. /goal <text>
sets a new goal at once, replacing the one the chat had without a
question, and the goal bar says what it replaced. /goal clear and
/goal resume act on the goal; typing "/goal " lists resume and clear
for the goal the chat has. None of these is sent as a message. In a
new chat, /goal <text> creates the chat first.

The command sits in the Context group of the shared command registry,
on the chat surface only, and not in a chat that a trigger or another
run started. A skill named goal is reached through /skill. Unit tests
cover the parser and the menu items; the Playwright spec covers the
card, setting, replacing, resuming and clearing from the box.

* Add /loop to the chat

/loop [interval] <prompt> starts a loop in the chat; /loop list shows
the loops of the chat with the code that /loop stop takes, and
/loop stop [id] stops one or all. The command is in the slash
registry: after "/loop " the menu offers list and stop, and after
"stop " the loops of the chat.

A loop prompt that invokes a skill (/review the diff, or
/skill review the diff) runs as the person's skill command would: the
model gets the skill's text, and the transcript shows the words, the
skill's chip and the loop label. The server checks the skill when the
loop starts and at each run; any other command is refused with the
reason.

Assisted-by: Claude:claude-opus-5-5

* List the loop settings on the Settings page

The five limits of the loops of the chats show under Tools with the
other chat settings: the shortest interval, the runs per loop, the
loops per chat and per user, and the loop runs per day. All apply at
once.

* Clear a sent Home draft when the page goes away too

Home clears the draft of a sent message when it closes, so the text
stays visible while the composer moves into the new chat. While the
chat page still loads, a reload or a closed tab could come first, and
the sent text came back on Home. Leaving the page now clears it too.

* Expect the chat's own load_skill tool in the agent prompt spec

The spec that keeps the agent engine's text out of the prompt also
required that no load_skill tool or mention reach the model. Chats now
offer their own load_skill tool and the skills index tells the model to
call it, so the spec failed. Keep the checks on the engine's own skill
and command text, and check that the chat's tool is offered.

* Read the user's scripted tool call in the mock model

The chat prompt now names the chat's work folder, and the folder name
comes from the chat title, which holds a cut copy of the user message.

system prompt, and called the tool with broken arguments over and over.
Read the last marker, the one of the user message.

* Keep the phone targets of the inbox at 44 pixels in every build

On a phone the inbox close button and the item actions must be 44
pixels wide. Their rule had the same weight as the kit's .dk-btn
min-width, so the order of the stylesheets decided. The single-chunk
coverage build puts the kit later and the close button shrank to 28
pixels. Scope both rules to their container so they win in any order.

* Let the about-you spec accept the sidebar's own seen date

When the user has pages, the sidebar writes the date of its New label

first, so the saved record held that date as well and the exact
comparison failed. Check that the uploaded seen record is kept.

* Give the typed-while-working chat spec time for two turns

The spec waits up to 30 seconds for each step, but two turns of the

the default 30 second test limit cut it under load. Set its limit to
90 seconds.

* Scope the foundation spec's state query to the sheet header

The details pane now repeats the observed state under Health, so a
role query for "State: Off" inside the add-on sheet matched two
elements and failed in strict mode. The administrator-manages spec,
and the two specs after it, did not run.

Query the chip in the header (.ad-pane__meta), which is the state the
administrator sees next to the add-on's name, through one helper used
for all three assertions.

* Wait for the page to read each apps answer in the registry polling spec

The spec moved the page clock as soon as the stand-in saw a request.
The registry sets its next timer only after it reads the answer, so on
a slow runner the clock could pass the due time of a timer that did not
exist yet, and the next read never came. With the CPU throttled ten
times, the old spec failed in 3 of 3 runs.

The spec now counts the answers the page has read and lets queued work
finish before it moves the clock. It pauses the clock before it leaves
the page, and it tries the pause again when a slow machine passed the
target time. The assertions do not change: one read at once, one read
per interval and no faster, and no read after the disable.

* Close the egress test listener only after it accepts

The dial helper of the egress proxy specs closed its listener when it
returned, while the goroutine that accepts the connection could still
be waiting to run. On a loaded runner the listener sometimes closed
first. The kernel then reset the connection that was still in the
accept queue, the spec's write consumed the reset error, which the
spec ignores, and the next read saw EOF. The spec failed with
"unexpected EOF" before the proxy got the request.

Wait for Accept to return before the listener closes, then start the
proxy handler on the accepted connection.

The host backend promises a fixed environment, but bash -lc reads
/etc/profile and the user's dotfiles. On macOS path_helper rewrote PATH

into 'bash --noprofile --norc -c' in the host backend only, and make the

* Answer the command card in the platform turns and 400 a bad answer

The tool-list spec of the platform suite timed out: without accounts
the one person is an administrator, so the chat has the built-in bash
in ask mode. The tool list is sorted and bash is first, and the mock
model calls the first tool, so every turn waited five minutes for a
yes on the command card. The turn helper now refuses each card it
sees, as a person who clicks deny, and the turn goes on to its step
limit. bash stays in the checked list.

An administrator who posts a consent with no card id or an unknown
decision got 403 "only an administrator can allow commands". That is
a bad request, not a refusal: it now answers 400, as the swagger
already says, and the route check for administrators passes.

* Let a chat switch off its shell, file, media, collection and sub-agent tools

The Tools menu of a chat switched only three groups of built-in tools:
web, saved_agents and triggers. A person could not keep a chat away
from the shell, the files, the helper models, the collections or the
sub-agents.

Add five groups to the registry of built-in tools, all on until the
chat switches them off:

- shell: bash, whoever serves it. The Sandbox add-on's bash and the
  built-in bash on this machine both go, and the add-on list reports
  commands switched_off. The row stays listed when nothing can run
  commands, not usable, with the reason.
- files: the file tools and read_document.
- media: describe_image and transcribe_audio.
- collections: list_collections and search_collection, usable only
  for a user with the collections feature.
- subagents: spawn_agent. list_agents and /agent follow it.

The registry gets two flags. External marks a tool that its own code
builds for the turn (with the wrappers it needs); the registry lists it
in its group and Hidden tells the builder what the chat switched off.
Covers makes a group's switch also hide the add-on tool that replaces
the built-in one. PUT .../builtins, the panel, the draft list and the
fallbacks use the existing group code.

A sub-agent follows the switches of its parent chat. The turn prompt
is built from the final tool list: no file tool names, no skill
writing hint, no work folder and no rules pointer when the chat cannot
use files, no describe_image when the helper is off, and a commands
block that says the person switched commands off.

* Queue the edited chat message after the first step starts

The spec queued its message as soon as the chat showed a busy state.
The turn is busy before its first model request starts, and that
request takes every message that waits. With the chat's tools and
skills, the first request now starts a few hundred milliseconds after
the turn, so the message went with it, and the edit got 409 "already
delivered" (5 of 6 local runs).

Wait until the answer streams, as the Stop spec does: the request is
running then, and the queued message waits for the next step.

* Give the reload chat spec a turn that outlasts the reload

The spec reloaded the page during a 3 second turn and expected the
page to show the turn still running. A reload of the coverage build
on a busy runner takes 4 to 5 seconds (measured with a 6x CPU
throttle), so the turn had ended before the page could show it. With
the 30 second turn the page always showed it running, so the resumed
state works and only the window was short.

Add MOCK_LONG_STREAM_MEDIUM to the mock model, a turn of about 10
seconds, and use it in the spec with a 60 second limit.

* Wait for the chat page after the Home hand-off in the specs

Send on Home changes the address inside a view transition, and the
chat page mounts about 35 ms later. Specs that waited only for the
address acted on Home in between:

- The title spec pressed Ctrl+K at once, because the server names a
  chat after its first message as it arrives, so the title poll ends
  at once too. The key reached the page before the chat page listened,
  and the menu did not open (3 of 3 presses at 0 ms failed, all at
  300 ms and later passed).
- The Back spec went back before the chat page was drawn. Home was
  never closed, so its draft of the sent message stayed in the box.

startChat now waits for the chat page, the title spec for the title
in the chat header, and the Back spec for the chat page before Back.

* Accept a resolved user.json conflict in the quiet page specs

The sidebar notes in the seen record of user.json the first day it
labels Pages as new, and saves it from the version it read. All specs
share the test server's one user, so tabs of other workers save the
same record at the same time: one gets 409 and useSeen reads the file
again and saves once more. Three tabs that open /app/files at once
give 200, 409, 200. The quiet check of the shell pages counted the
409 as a problem.

Ignore a 409 on PUT /api/chats/wellknown/user in that check.

* Check only the spec's own items in the Trash after the reload

After Empty Trash and a reload, the spec expected the whole Trash to
be empty. The Trash belongs to the test server's one user, and specs
of other workers move files to it meanwhile, so CI saw "In the Trash:
3 files, 356 B." after the reload.

The checks right after Empty Trash stay. After the reload, check that
the server's Trash, the Trash tab and Files do not hold the spec's
items, once each list has loaded.

* Show the new tool groups in the chat Tools menu

The Tools menu lists the groups of built-in tools that the server
sends. The five new ones need words and an order, and the shell row
needs to say who runs the commands.

Name the groups in all nine locales (Run commands, Your files, Images
and audio, Collections, Sub-agents) and order the rows by what they
reach: the shell and the files first, the triggers last. The shell row
carries a chip with the provider (Sandbox or This machine) and a line
under it that says the commands run isolated, or a warning when they
run on this machine. When nothing can run commands the row is disabled
with the words of the commands notice. A switched-off sub-agents group
also turns /agent off in the composer.

The specs cover the rows, the off and on requests, the bulk actions,
the provider chip, the disabled reasons, the draft on Home and a real
server round trip.

Assisted-by: Claude:claude-opus-5-5

* Document the groups of built-in tools a chat can switch off

The Tools menu section described only the web, triggers and saved
agents groups. List every group with its tools, say which groups the
server may leave out and why a row can be not usable, how Run commands
covers both providers, what the model is told when a group is off, and
that a sub-agent follows its parent's switches.

* Fix the host command consent spec for the 400 contract

The consent route answers 400 for a body without a card id or with a
decision other than once or deny, whoever asks. The spec still expected
403 for always from an administrator. Cover the malformed answers for
an administrator and a user, each in their own chat, keep another
user's chat at 404, and say it in the chats guide.

* Find the web tool group by name in the route spec

* Give Skills its own sidebar item

Skills work in every chat, but the sidebar filed the page under Agents
and only agent skill chips linked to it. Add a Skills item right after

the skills pages.

* Add Manage skills to the skills picker and a /skills command

The picker now ends with a Manage skills link, and /skills opens the
Skills page from the composer on Home and in a chat. The picker keeps

rows. Words are added in all nine locales.

* Keep Home on screen while its widgets load their strings

A Home widget reads the pages strings, and i18next loads a namespace
the first time a component asks for it, by suspending. Home had no
Suspense boundary of its own, so the route's boundary hid all of Home
(display: none) and showed the route fallback until the strings came.

A widget shows only after home.json is read, so this happened after
the composer was already drawn. Focus given to the composer in that
window went nowhere, and a key typed then was lost. The slash menu
spec failed in CI this way when another spec had written widgets to
the shared home.json: the box was empty and the body had the focus.
With widgets in home.json the composer was hidden right after it
appeared on 5 of 5 loads, and the spec failed 1 or 2 times in 5.

The examples and the widgets now have their own boundary with no
fallback, so only they wait. A new spec holds the pages strings while
it types in the composer; it fails without the change (the composer
never takes the focus) and passes with it.

Assisted-by: Claude:claude-opus-5-5

* Send the stubbed file change after the Files page read the folder

The change feed spec answered the first stream request with the change
at once. The app shell (the appearance sync) opens the shared stream
when the app starts, before the Files page chunk has loaded, so on a
slow runner the change reached a tab where nobody watched the folder
yet and was dropped. The page then never read the folder again, and
the spec failed on all three CI attempts. A CPU throttle of 8 makes it
fail 3 of 3 times locally.

On a real server the page's own first read would already show such a
change. The stub now holds the change until the page has read the
folder; the page subscribes in the same commit as that read, so the
change arrives with a subscriber in place. The resume check is kept.

Assisted-by: Claude:claude-opus-5-5

* Give the oversized 3D input as a sparse file, not a buffer

The spec built a 32 MiB buffer and passed it to setInputFiles.
Playwright sends a buffer to the browser over the protocol: that step
alone took 5.5 s on an idle machine, and on the loaded CI runner the
test hit the 30 s timeout on all three attempts.

It now writes a sparse file of the same size to the test output folder
and passes its path, which the local browser opens as is. The page
still checks the size before it reads the file, so the toast and the
no-request assertion are unchanged. The step takes milliseconds.

Assisted-by: Claude:claude-opus-5-5

* Check the tool line, not the tool name, in the tool call journey

The spec looked for /list_files/ in the transcript. The user's own
message holds that name, so the check could pass before any tool ran.
Once the model's call streamed, a second element matched, and the
strict locator failed (2 matches on the first attempt, 5 on the
retry).

It now waits for the activity line that the tool run adds ("Listed
/"), which only shows after the tool ran.

Assisted-by: Claude:claude-opus-5-5

* Measure the proposal card and its neighbours in one frame

The layout spec read the boxes of the message text, the card and the
message actions with three boundingBox calls. They are viewport
positions taken in three frames, and the transcript scrolls to its end
while the card fills in. On the phone the actions were read after a
scroll and came out 156 px above the bottom of the card.

The three boxes now come from one page.evaluate, so they are read in
the same frame. The order assertions are unchanged.

Assisted-by: Claude:claude-opus-5-5

* Read the page fixture time when the page is served

The task board fixture of the discovery and Pages specs set its
change time once, when the file loaded. A worker loads it once and
keeps running specs, so a spec that ran two minutes later read
"Changed 2 minutes ago by the assistant" where it expects "just now".

The change time is now a getter, read when the fixture is serialized
into a response.

Assisted-by: Claude:claude-opus-5-5

* Check a background process without /proc in the host test

The alive helper read /proc/<pid>/stat, which macOS does not have, so it
reported every process as dead and the spec failed there with "did not
survive the suspend". Use signal 0 for existence and ps (or /proc where
present) to tell a zombie from a live process.

* Keep the composer switch menus at their own height

The base rule of the dropdown menu caps it at 320px and lets it scroll.
The switch menus set their own height with a rule of the same weight in a
lazy sheet, so which one won depended on the order the sheets loaded in.
When the base rule won, the picker showed a few rows, and a click on a row
at the edge of the list scrolled the list by a few pixels.

Double the class on the switch menu rules so they win in any order, and
add a test that loads the base rule last.

* Show what applies in the chat Network switch

The Network row highlighted the choice stored with the chat, so a
chat that asked for All public sites under an administrator limit of
Off showed All highlighted although it was disabled and not in effect.

Highlight the effective choice, the lower of the chat's choice and the
limit, which the server already computes. When the chat asks for more
than the limit, say so in one line instead of highlighting it. Add a
line that the limit is set by the administrator, and tell the host
network line that limits need the Sandbox add-on.

Assisted-by: Claude:claude-sonnet-5-5

* Design the host components that add-ons reference

The host UI names the Sandbox and the Web add-ons to place their server
settings, and the chat's Network row links to the global Settings page.
Describe a closed registry of host components that an add-on references
by ID in its manifest, entitled by the existing host operation grants
and tool shadows, so the controls live on the add-on's own page and a
second add-on can reuse them with no host change.

Assisted-by: Claude:claude-opus-5-5

* Let an add-on ask for host controls in its manifest

An add-on had no way to say that a host-owned control belongs on its
page, so the host UI placed those controls by add-on name. Add
ui.controls, a list of IDs from a closed registry of host controls:
network-policy (the network of the commands an add-on runs) and
tool-providers (the rows of the built-in tools it replaces).

The host decides which controls it draws: EntitledControls keeps a
control only when the add-on holds its host operation grant and
replaces its built-in tool. The field is optional, so every existing
manifest stays valid.

Assisted-by: Claude:claude-opus-5-5

* List the host controls an add-on is entitled to

The apps list now carries ui.controls with the host controls the
manifest declares and the host setting entitles the add-on to: the
manager passes each add-on's host operation grants to the list.

GET /api/chats/{id}/egress gains addon, the add-on that runs the chat's
commands when it has the network-policy control, so the chat can draw
its Network row from that add-on and link to its settings. applies and
applies_reason keep their meaning: the policy holds with or without the
control. The model and the 400 error no longer send an administrator to
Settings > Tools for the limit.

Assisted-by: Claude:claude-opus-5-5

* Draw the host controls on the add-on's own page

The host UI placed the Sandbox network and the tool rows by add-on name
(SERVER_SETTINGS), showed a read-only summary on the add-on's Settings
tab, and linked the chat's Network row to the global Settings page.

Add a registry of host controls keyed by the IDs of the contract. The
Settings tab of an add-on draws, below its own sections, the controls
the apps list gives it, in one form with the pending bar of the
Settings page: network-policy reuses the network section and its
setting rows, tool-providers the rows of the built-in tools the add-on
replaces. The chat draws its Network row only when the server names an
add-on with network-policy, and the administrator link opens that
add-on's tab. The row itself is unchanged.

The Settings page keeps the settings of features that exist without an
add-on, points to the add-on where one serves them, and no longer
lists the network settings. Its old address opens the add-on's tab.

Assisted-by: Claude:claude-opus-5-5

* Ask for the host controls in the Sandbox and Web manifests

The Sandbox asks for network-policy and tool-providers, so the network
of its commands and the bash row are drawn on its own Settings tab and
its chats get the Network row. The Web add-on asks for tool-providers
only: it holds no egress grant. The manifest tests check that the
default grants entitle each add-on to what it asks for.

The proxy's refusal now sends the model to the Sandbox Settings tab
instead of Settings > Tools.

Assisted-by: Claude:claude-opus-5-5

* Keep the button of the network pointer row at its size

The row used the wide layout of the tool rows, so its Open settings
button stretched across the page. Use the plain setting row, which
puts the button on the right like the other controls.

Assisted-by: Claude:claude-opus-5-5

* Fix the add-on contract inventory and the apps Swagger fixture

The contracts case inventory missed the six host control specs, so
verify.sh rejected the Ginkgo report. List them.

The Swagger spec test never saw `controls` in the emitted UIView JSON
because its fixture left the omitempty field empty. Set it there.

Assisted-by: Claude:claude-sonnet-5-5

* Add the host controls spec to the apps inventory

The apps suite ran one more spec than scripts/addons/suites.json
listed, so verify.sh rejected the apps report as an inventory
mismatch. List the new spec in the report inventory and in the
suite's aggregate case list. Every other Ginkgo suite was re-run
and matches its inventory.

* 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 756b019ce4 [httpclient] validate redirect targets and pin dialed addresses for user URLs (#12853)
fix(httpclient): validate redirect targets and pin dialed addresses for user URLs

Clients that fetch user-supplied URLs followed redirects without checking
the target, so a public host could send them to a loopback, link-local
or private address. The host was also resolved twice, once to validate
it and once to connect, so a changing DNS answer could bypass the check.

Add httpclient.WithExternalOnly. It validates every redirect hop against
the external URL policy and, for the default transport, resolves the
host, refuses it if any address is non-public, and dials the validated
address. Environment proxies are not used for such clients.

Move the policy (ValidateExternalURL, IsPublicIP) into pkg/httpclient
so it can be used without an import cycle; pkg/utils keeps delegating
to it. IsPublicIP now also refuses 100.64.0.0/10, 0.0.0.0/8,
192.0.0.0/24, 198.18.0.0/15, 240.0.0.0/4, multicast, and NAT64
addresses that wrap a non-public IPv4 address.

Use the option for the base64, image, audio and video downloads, and
drop the video client's own per-hop 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.

* 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

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.

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.

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(ui): add an add-ons control to the chat header

Add-on tools were on or off only through the /addons command, with a toast
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
turned off. Both keys are consumed so they do not reach the backend.

this way; this change states the rule beside the unavailable state and
pins it in the specs.

* 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.

The setting defaults to off in the config, the runtime settings and the

owner upgrades an installed add-on through the manager; with it off,
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.

The add-ons page describes the setting, its schedule and its default.

mudler-agentandEttore Di Giacinto 50c284fdcc fix: make the remaining VerifyPath checks effective (#12326)
utils.VerifyPath joins its argument onto the base path, so a path that
the caller already joined always passes. Several callers gave it joined
paths, and their checks could not fail:

- modeladmin (config view, patch, edit, pin and state): the config file
  path from the loader. A config loaded from outside the models
  directory (--models-config-file) could be pinned, and the pin wrote
  the outside file. The patch and state paths stopped later, in the
  mutation snapshot, with a different error.
- core/backend/tts.go: the model path joined onto the models path.
- The trellis2cpp and stablediffusion-ggml backends: option paths
  (*_path) joined onto the model path. A "../" value outside the model
  directory was accepted.

Add utils.VerifyResolvedPath for a full path. modeladmin and tts use
it. The backends now check the relative option value before they join
it. A rename in modeladmin checks the new relative name.

For models from a config file outside the models directory, the admin
API and web UI now return ErrPathNotTrusted for view, edit, pin, and
enable or disable. The docs describe this.

Zelys 76927ccde3 fix(utils): reject tar hardlinks that escape the extraction root (#11266)
* fix(utils): reject tar hardlinks that escape the extraction root

ExtractArchive pre-scans archive members and rejects symlinks, but tar
hardlink entries carry a regular file mode and so pass that check.
Header.Linkname was never validated, so an archive could create a link
to a path outside the destination directory.

Validate Linkname with the same path check already applied to member
names. Hardlinks that resolve inside the extraction root still extract,
so ordinary archives are unaffected.

pkg/oci/image.go already resolves tar.TypeLink targets before using
them; this brings the archive extraction path in line with it.

Add two cases. The first uses a .tar.gz, where ExtractArchive binds a
Tar config with OverwriteExisting set, and follows the link entry with a
regular entry of the same name. Before the fix that pair linked to a
file outside the root and then truncated it through the link, which the
plain .tar case does not reach. The second extracts a hardlink whose
target is an earlier member of the same archive, covering the claim that
ordinary archives are unaffected.

* backend(audio-cpp): harden seconds_to_samples against NaN and overflow

seconds_to_samples is the one entry point fed by untrusted-shaped input: a
float-seconds timestamp off the wire, or a boundary from a model that diverged.
Its guard covered only the low side, so NaN and out-of-range values fell through
to an undefined double-to-int64 cast and came back as INT64_MIN. A hugely
negative sample index used later as an offset or a length is a wild pointer
rather than merely a wrong timestamp. Reject NaN with the !(x > 0) form and
saturate before the cast.

Also round instead of truncating there. These functions exist to cross the float
seconds boundary the VAD and diarize messages use, and truncation lost a sample
about half the time on the samples-to-seconds-and-back round trip, starting at
n=1.

Pin the decode scale at INT16_MIN, pin nanosecond truncation on a nonzero
fraction, and record why the clamp argument order in f32_to_s16le is

* backend(audio-cpp): map NaN PCM samples to silence explicitly

f32_to_s16le relied on std::min argument order to keep a NaN sample away from
std::lround, whose result is unspecified for NaN. That was too subtle to rest on
a comment, and the comment was itself wrong: it warned against a spelling that
the outer std::max already catches, while three real spellings leak, including
std::clamp, which is the idiomatic C++17 way to write the same clamp and so the
likeliest future edit.

Divert NaN before the clamp and encode it as 0. A NaN sample rendered as a
full-scale click is worse audio than a dropped one, and this unit converts audio
that may have originated off the wire.

Pin it with an exact-value check rather than a range check, since all three
outcomes the plausible spellings produce are finite and inside full scale, plus
an invalid-operation check that fails unless the NaN is diverted before any
ordered comparison. That second check is what catches modernizing the clamp and
dropping the guard together.

Also bound the seconds round-trip comment, which claimed unconditionally what
holds only below roughly 2^23 samples, and document NaN, saturation and that
bound in the header.

* backend(audio-cpp): keep a nested speaker turn's own label

A segment sourced from speaker_turns re-derived its speaker by greatest
overlap. A turn's overlap with its own span is the largest possible, so a turn
nested inside another speaker's turn could only tie with the container, and the
tie went to whichever came first. sortformer_diar binarizes each speaker
independently and sorts by start sample, so the container always comes first
and the interjecting speaker was silently erased from DiarizeSegment.speaker.
choose_segment_spans now carries the label out with the span.

Also pins the nearest-segment fallback against measuring from either endpoint
or from segment position, which a trailing-only stray word could not do, and
exercises the empty-word guard in join_words. Two fixtures that pin a rule but
do not mirror any pinned family are relabelled defensive.

* backend(audio-cpp): serialize runs with a wedge-aware guard

audio.cpp sessions are not reentrant and a wedged CUDA call cannot be
cancelled, so a plain mutex would pile every worker thread behind a stuck GPU.
Callers waiting past the configured bound, or arriving while the holder has
already overrun it, fail fast instead.

A caller that queues behind a healthy run deliberately does not stamp the
clock: only the thread that takes the lock does. Stamping on arrival would
restart the wedge clock on every request and hide a stuck run from everyone
behind it, which is the pile-up this guard exists to prevent.

* backend(audio-cpp): serialize inference through an InferenceLane

One audio.cpp model is loaded per backend process and its sessions are not
reentrant, so concurrent gRPC handlers have to take turns. Serialization alone
is not enough: a wedged GPU call cannot be cancelled from userspace, so an
unbounded queue behind one stuck run would swallow every gRPC worker thread
until the process is useless.

InferenceLane gives handlers a lane with room for one runner. LaneEntry occupies
it for a scope and gives it back on every exit, including an exception, and is
the only way to take the lane at all: occupy/vacate are private with LaneEntry
as the sole friend, so a caller cannot acquire without holding something that
releases. LaneEntry is immovable on purpose, because a moved-from entry would
have to stop releasing while the lane still recorded it as occupied.

A caller either waits indefinitely or brings a millisecond budget. A bounded
caller that cannot get in fails instead of waiting on, and a bounded caller
whose budget is already shorter than the age of the run in the lane fails
immediately, which is what stops a queue forming behind a wedged run. The two
failures carry different text: one names the wait it exhausted, the other states
the measured age of the run without claiming to know why it is long, since a
short budget meeting a legitimately long run lands there too.

The run's age is stamped only after acquisition. A waiter that published itself
as holder would restart the measurement and hide a genuinely stuck holder from
every caller behind it.

Budget negotiation and the overrun decision are pure functions taking their
inputs explicitly, so both are covered without threads or sleeping. The
per-model ceiling arrives as an int of milliseconds; a request may tighten it
and may never loosen it.

Replaces the previous run_guard unit, which was a derivative of an
Apache-2.0 file upstream and could not stay in an MIT tree. Written from a
behaviour contract with no reference to the removed code.

Tests: 65 checks, standard library only, single translation unit, clean under

missing coverage and the tests were extended until they died. ThreadSanitizer

Review of the previous commit found the B10 test could not fail for the reason
it was named. It aged the in-flight run to about 120 ms and then tried two
budgets, 30 ms and 60 ms, both under that age, so both callers took the
fail-fast path. "The two failure modes do not share one message" was comparing
two fail-fast messages that differ only in the budget they print, and the
timeout path was never reached. The second budget is now 400 ms, well over the
run's age, so that caller queues and times out, and a new check asserts which
path each caller took instead of inferring it from inequality. A mutant that
makes the fail-fast path emit the timeout message previously died only on B4 and
B8 checks; it now also dies on B10.

Comment-only changes elsewhere. LaneEntry now says it is not reentrant and does
not detect reentrancy: a second entry on a thread that already holds the lane
surfaces as LaneUnavailable with a positive budget, but parks silently in
unbounded mode, which matters because a handler may hold one across a whole
stream. The immovability note now names the shapes that work, an optional
emplaced in place or a unique_ptr, rather than saying to hold the entry
indirectly without saying how; all three documented forms were compiled before
being written down, which is how the note came to say that an optional of an
immovable type cannot itself be returned.

The header's explanation of why fail-fast exists is reworded. Two clauses traced
back to a specification written after reading the Apache-2.0 upstream header,
and while that was judged de minimis, this unit was rewritten precisely to carry
no upstream expression at all.

The margin table in the report was also wrong about which wall-clock margins are
load-sensitive: there are four, not one, and the tightest is the B3 arrival
check, which is now flagged at the call site. No margin value changed and none
moved across 65 runs.

* backend(audio-cpp): gate model loading on the audio.cpp family

Refuses any GGUF without an audiocpp.model_spec.family key and any non-GGUF
path without an explicit family option, so the model loader's greedy backend
probe cannot bind an unrelated llama.cpp GGUF to this backend (#9287).

* backend(audio-cpp): load models and cache sessions per task

Loads one ILoadedVoiceModel and creates an IVoiceTaskSession lazily per
(task, mode), so the same model serves both the unary and streaming RPCs.
LoadModel derives the family from GGUF metadata or an explicit option and
fails with INVALID_ARGUMENT otherwise, so a failed load is a gRPC error the
backend probe can see.

audiocpp_backend::Task mirrors engine::runtime::VoiceTaskKind positionally,
and drift there is silent: every unit still compiles and every test still
passes while the backend runs a different task. Two mechanisms pin it. The
static_asserts in loaded_model.cpp catch an insertion or a reorder, and
-Werror=switch on that one file turns an appended upstream enumerator into a
build failure rather than a warning in a 600 file log.

* backend(audio-cpp): stop aborting the process on SIGTERM

The signal handler called grpc::Server::Shutdown directly. Shutdown takes an
absl::Mutex, which is not async-signal-safe: the handler can interrupt a thread
already holding that mutex, and abseil's deadlock detector responds by aborting.
Every SIGTERM therefore ended in exit 134 and a 'dying due to potential
deadlock' stack rather than a drained shutdown.

The handler now sets a lock-free atomic and returns. Server::Wait moves to a
helper thread so the main thread can poll that flag and call Shutdown itself,
outside any signal context. A condition variable would not have helped, because
notifying one from a handler is not async-signal-safe either.

SIGTERM and SIGINT both exit 0 with no stack trace, where both previously
exited 134.

* backend(audio-cpp): correct the status, lifetime and state contracts of LoadedModel

An environment fault during session creation was reported as UNIMPLEMENTED. A
missing libggml-cpu-*.so surfaced to the client as 'family silero_vad advertises
vad/offline but refused to create the session: Failed to initialize CPU
backend', which tells LocalAI the model cannot do this and must never be
retried, and sends an operator hunting a capability bug instead of a packaging
one. A throw from create_task_session is now a plain runtime_error, so it maps
to INTERNAL. Only a null return, where the family genuinely declined, stays a
CapabilityError.

The model.'s task: option was parsed and then dropped: it lived in a local that
died at the end of LoadModel and had no route to RequestShape::pinned_task.
LoadedModel now keeps it and exposes pinned_task().

The global model becomes a shared_ptr reached through snapshot(). An audio RPC
runs for seconds and cannot hold g_model_mu for its duration, so under a
unique_ptr a Free arriving mid-request would destroy the model underneath it.
Handlers now take a counted reference and whichever finishes last does the
teardown, outside the lock.

session_for documents the streaming state contract rather than resetting the
session itself. Resetting on a cache hit was tried first and is not possible:
silero_vad throws 'session prepare() must be called before Silero VAD reset()',
so it would turn an ordinary second fetch into a hard error. start_stream's base
implementation is already a reset, so a caller that runs prepare then
start_stream per stream gets a clean session; a probe against the bundled
silero_vad confirms an identical replay when it does and a carried-over stream
when it does not.

Also: an unknown backend: name is rejected before the model loads rather than
after; MainGPU is parsed instead of passed through std::atoi, which turned
'gpu1' into device 0 silently; and device carries a device_set flag, because 0
is both the default and a real device index, so MainGPU was overriding an
explicit device:0 that the neighbouring threads: handling promises will win.

* backend(audio-cpp): serve the VAD and Diarize RPCs

Both emit float seconds, converted from the runtime's sample-index spans, and
both take a counted reference to the loaded model through snapshot() and hold it
for the whole call: a Free arriving mid-request drops only the global's
reference, so whichever request finishes last destroys the model instead of one
of them running on freed weights. An AddressSanitizer build reproduces exactly
that heap-use-after-free inside ggml_vec_dot_f32 when the handler keeps a raw
pointer instead, which is why the shape is what it is.

The inference lane is taken before session_for, not after. session_for reads and
writes an unsynchronised session cache and the offline run calls prepare(),
which mutates the session, so both belong inside the lane.

Diarize routes before it reads the input file, so a family that cannot diarize
at all says so rather than complaining about the audio first. Its per-segment
text stays empty because audio.cpp's SpeakerTurn carries a span and a speaker
label only, and nested or overlapping turns are passed through untouched: a
sortformer turn inside another speaker's turn is correct output for overlapped
speech, and LocalAI is overlap-tolerant downstream. Duration counts frames
rather than floats, so a stereo input does not report twice its length.

Verified end to end against upstream's bundled silero_vad, which needs no
download, using the bundled 16 kHz speech asset: a synthetic tone returns
nothing, correctly, because silero detects speech and a sine is not speech.

* backend(audio-cpp): enforce ModelIdentity on VAD and Diarize

audio-cpp was the only C++ backend without the model-identity guard, and no
later task in the plan added it. pkg/grpc/server.go enforces checkModelIdentity
on exactly these two RPCs, for the reason #10952 records: in distributed mode a
worker can recycle a stopped backend's gRPC port for another model's backend,
and the controller's liveness-only probe cannot tell a stale cached route from a
live one. Without this guard a stale route gets a different model's VAD or
diarization answer back with a 200.

The loaded identity lives on LoadedModel rather than in a separate global, which
is where this differs from llama-cpp. A handler holding the model through
snapshot() then necessarily judges against the identity that model was loaded
with, and a concurrent reload cannot swap one without the other. The refusal is
NOT_FOUND carrying the verbatim grpcerrors.ModelMismatchSentinel substring.

session_for and run_offline now take a const LaneEntry & proof-of-holding
parameter. The rule that both must run under the inference lane was prose, which
is exactly how the plan came to specify the inverted order; it is now a compile
error. Restoring the inverted order fails to build rather than racing on an
unsynchronised session map with a mutating prepare().

Diarize's speaker-hint comment claimed the dropped hints were "not a silent
failure". From the caller's side that is what they are, and backend.proto
documents num_speakers as forcing, so the comment now says plainly that the
forwarding is dead for sortformer and that the family which lands must either
honour num_speakers or refuse it. read_audio_file inspects the error_code from
exists(), so an unsearchable parent directory no longer reports as a missing
file. The VAD handler records the stimulus that actually works, since silero
correctly ignores synthetic tones and the next task would otherwise rediscover
that.

* backend(audio-cpp): make the lane and identity guards structural

Two hardenings ahead of the eleven handlers still to be written, both of which
get harder to retrofit later.

The lane proof-of-holding parameter was a const reference, which binds to a
temporary, so session_for(rpc, shape, model->acquire(0)) compiled. Each such
temporary dies at the end of its own full-expression, releasing the lane between
two calls that must share one: precisely the split the parameter exists to
prevent, and the form a future author is most likely to reach for because it
reads as tidy. A non-const reference requires an lvalue, so the temporary form
now fails to compile while the named-local handlers build unchanged. The header
comment no longer implies the check is total either: it proves a lane was taken,
not that it is this model's lane.

The identity check was two lines each handler had to remember, with nothing
failing if a new one forgot them and no C++ equivalent of
model_identity_modalities_test.go to notice. snapshot() becomes
snapshot_unchecked(), whose only legitimate caller is Status, since HealthMessage
carries no ModelIdentity. Handlers go through snapshot_for(), which takes the
counted reference, refuses when nothing is loaded, and runs the identity check
before anything can route. Every handler already has to call something to obtain
the model, so the guarded call is now the shortest path and skipping it means
deliberately typing snapshot_unchecked. A convention that has to be remembered
can rot; this cannot.

Verified: the temporary-argument and inverted-order forms each fail to compile
with the expected diagnostic, the real handlers build, and bypassing the guard in
Diarize alone turns the identity test red on that RPC while VAD stays green.

* backend(audio-cpp): serve the AudioTranscription RPC

Adds result_map, the engine-to-proto boundary, and wires the offline
transcription RPC.

The handler branches on the ROUTED task: for Asr the request's prompt is
whisper-style decoding context and becomes a request option, for Alignment
the same field IS the transcript to align and becomes the text input.
Routing has already decided which.

The result text is TaskResult.text_output verbatim and is never derived
from the segments. audio.cpp carries transcript text in text_output and
nowhere else, so deriving it returns an empty transcript for every
producer that reports segments without word timing. transcript_assembly
already enforces that; this commit's job is not to undo it at the proto
boundary, and result_map_ctest pins it there.

read_audio_file now takes the sample rate the caller needs. Both file-fed
speech handlers ask for 16 kHz mono, for two reasons: silero_vad and
sortformer_diar refuse anything else outright, which turned an ordinary
44.1 kHz upload into INTERNAL, and nemotron_asr emits word timestamps in
its own 16 kHz feature domain whatever the input was, so only a 16 kHz
buffer makes the emitted nanoseconds right. Zero keeps the file's native
rate and channels, which is what source separation will need.

LoadedModel::check_can_serve answers a capability refusal before the lane
is taken and before the input file is read. Routing is a pure read of the
immutable capabilities, so a model that cannot serve an RPC no longer
waits out somebody else's run to say so. VAD and Diarize use it too.

* backend(audio-cpp): stop linking sentencepiece's vendored protobuf

engine_runtime links sentencepiece, whose default SPM_PROTOBUF_PROVIDER
builds the protobuf-lite 3.14.0 sources it vendors. The generated
backend.pb.cc is built against the toolchain's protobuf 3.21.12. Both
ended up in the binary: 476 google::protobuf:: symbols came from the
archive, 278 of them also defined by libprotobuf.so, and the archive won,
because once ld pulls a member in for sentencepiece's own code every
reference binds to the definitions that member carries.

The visible symptom is one function.
ParseContext::ParseMessage(MessageLite*, const char*) is what a generated
_InternalParse calls for a submessage field and for nothing else, so flat
messages parsed and nested ones did not: a TranscriptResult carrying
segments serialized to correct bytes that the same process could not read
back, and TranscriptLiveRequest, a oneof of submessages, could not have
been parsed at all. Underneath that, 3.21 generated code was running 3.14
arena, ArenaStringPtr and ExtensionSet code.

-Wl,--exclude-libs does not fix it. It makes those symbols LOCAL in
.dynsym and the parse still fails, because the binding was decided at
static link time and no visibility flag revisits it.

Setting SPM_PROTOBUF_PROVIDER to "package" before add_subdirectory points
sentencepiece at the protobuf the generated code was already built
against. Zero google::protobuf:: definitions remain in the executable
afterwards, every nested message round trips, and citrinet_asr, which
parses a SentencePiece ModelProto at load time and would break first if
this were wrong, still tokenizes and transcribes correctly.

* backend(audio-cpp): fix the segment text a transcription response is built from

Segment text is not decoration. core/http/endpoints/openai/transcription.go
routes response_format text, srt, vtt and lrc through
schema.TranscriptionResponse, which builds the entire body out of
Segments[].Text and never reads the top-level text. So for those four
formats the segment text IS the response.

nemotron_asr emits one word_timestamp per SentencePiece token, and the
word boundary is carried as a LEADING SPACE on the piece ("So", "me",
" call"). join_words inserted a space unconditionally, so
response_format=text returned "So me  call   me  na ture ," while the
correct sentence sat unread in the top-level field. The separator is now
chosen from the words themselves: whole words are space-joined, subword
pieces are concatenated, and one leading space anywhere selects the
latter. Concatenating the real nemotron pieces reproduces text_output
exactly, verified end to end.

This does not touch the top-level text, which is still text_output
verbatim. The rule that forbids deriving the transcript from the segments
is about the direction segments -> text; segment text has no source other
than its words.

Two smaller corrections in the same area:

timestamp_granularities ["word"] set only "word_timestamps", a key no
family in the pinned upstream reads. It now sets "return_timestamps",
which qwen3_asr does read and which both runs its forced aligner and
shortens its chunk window, so asking for word granularity no longer
silently returns nothing.

The request-option comment claimed more than it delivered. prompt,
translate and temperature are read by no ASR family, and are forwarded
only so a family adopting them works unchanged; the comment now says so
per key, and gives TranscriptRequest.diarize the same explicit treatment
threads already had.

Also: the shipping target now carries -Wall -Wextra -Wpedantic, which it
never did, so "the build is clean" starts meaning something; and
fill_transcript_result no longer swallows a null response pointer, since
answering OK with an empty transcript is the one failure mode this unit
exists to prevent.

* backend(audio-cpp): serve the AudioTransform RPC

Covers voice conversion, singing voice conversion, speech to speech and source
separation, the four tasks LocalAI's AudioTransform can represent.

AudioTransformResult carries one dst while htdemucs and mel_band_roformer
produce several named stems from a single run, so inference runs ONCE, every
stem is written as a sibling file <dst-stem>.<name>.<ext>, and params[stem]
selects which one dst receives, defaulting to vocals and falling back to the
first output. An unknown stem name is INVALID_ARGUMENT listing the real stem
names rather than a silent substitution, and the selection happens before the
first write so a refused request leaves no files behind. params[stem] is
consumed here and is not forwarded into the engine's request options.

The stem decision lives in stem_selection, which is stdlib only and therefore
tested by backend/cpp/run-unit-tests.sh. It also validates the names, because
they come from the model (htdemucs reads them from the GGUF's config.sources)
and each becomes a component of a path this backend writes: a name carrying a
path separator would escape the caller's output directory, and two stems
sharing a name would silently overwrite one another.

Both files are read at their native rate and channel count. Separation forces
it, since demucs and roformer refuse any rate but 44.1 kHz and lose the stereo
image that separates a centred vocal from a wide mix. The conversion families
all resample internally (seed_vc, vevo2, miocodec, chatterbox were each
checked), so passing the file through unchanged is also strictly better than
band limiting it to 16 kHz first.

Verified end to end against htdemucs f16 on a 44.1 kHz stereo mix: four stems
plus dst, dst byte identical to the selected stem, params[stem] selecting a
different one, an unknown stem refused with no files written, and mono input
preserved as mono output. Also against miocodec for the single output path,
where params[stem] is refused rather than ignored.

* backend(audio-cpp): refuse an impossible stem early, and stop blaming the caller for a failed write

Four fixes from the first review of the AudioTransform RPC.

check_can_serve now returns the resolved route, so params[stem] on a route that
is not source separation is refused from the route instead of after a full
inference: 11 ms rather than the 4.5 s a miocodec conversion costs, and far
worse on seed_vc or vevo2. The post-run refusal stays as the backstop for a
separation-routed family that returns no stems anyway. The typo'd-stem-name
case still needs the run, since no framework header publishes the stem names
before one.

Stem names carrying control bytes are refused. GGUF strings are length prefixed
and demucs reads its sources from JSON, so an embedded NUL survives to here:
two names differing only after the NUL are distinct std::strings, so the
duplicate check passes them, and then path::c_str() truncates both and they
open the same file. That is exactly the silent overwrite the duplicate check
exists to prevent, with the .wav lost as well.

A failed write is now INTERNAL rather than INVALID_ARGUMENT. The destination is
LocalAI's own generated-content directory, not anything the caller named, so a
full disk or a permission fault there is a server fault and is worth retrying,
which is the opposite of what INVALID_ARGUMENT tells a client. An empty output
path stays INVALID_ARGUMENT.

Two comment corrections and one clarification: the separators' required rate is
their checkpoint's declared samplerate rather than a hardcoded 44100, seed_vc
resamples with soxr and falls back to sinc-hann, and the "no files left behind"
guarantee covers a refused request, not a write that fails partway through the
loop.

* feat(audio-transform): stop folding every upload to 16 kHz mono, and name the separation stems

Two defects that made source separation unusable through LocalAI's own API,
even though the backend served it correctly over gRPC.

/audio/transform normalized every upload to 16 kHz mono s16 through
utils.AudioToWav, with no way past it. htdemucs and mel_band_roformer refuse
any rate but their checkpoint's own and separate a centred vocal from a wide
mix using the stereo image, so every separation request through the HTTP API
died with "HTDemucs prepare() sample rate mismatch: expected 44100, got 16000"
while the same call over gRPC worked. The fold is not wrong, it is
backend-specific: LocalVQE's echo cancellation genuinely wants 16 kHz mono and
needs the reference in the same shape. So it becomes a declaration,
BackendCapability.AudioTransformInputMono16k, set for localvqe and for nothing
else. A backend that declares nothing gets its upload unchanged, which means no
backend has to opt in to work. utils.AudioToWavPreservingShape is the
non-folding conversion: a 16-bit PCM WAV passes through byte for byte at any
rate and channel count, anything else is transcoded to WAV with its rate and
channel layout kept.

The other defect is that the run-once stem design bought nothing. A separation
backend writes every stem beside dst from one inference, but AudioTransformResult
carried only dst, so the other three were files no caller could find and a
caller wanting all four had to run four separations. AudioTransformResult grows
a repeated AudioTransformStem, the backend fills it, core/backend validates that
each path really is inside the generated-content directory it handed over, and
the endpoint publishes them as an X-Audio-Stems JSON header beside the existing
X-Audio-Input-Url. JSON because a stem name is the model's own string and could
contain any separator a hand-rolled format would use.

Verified end to end through the HTTP endpoint with htdemucs f16 on a 44.1 kHz
stereo file: 200 with a 44.1 kHz stereo body, all four stems named and fetchable
through /generated-audio/, body byte identical to the selected stem, and
params[stem]=drums returning a different one. The same upload sent to a model
whose backend is localvqe still reaches the backend as 16 kHz mono, confirmed
both by the engine's own rate refusal and by the persisted input file.

* fix(audio-transform): reject extensible WAV from the passthrough, escape stem URLs, convert stems with dst

Four fixes from the second review, plus one bug they made visible.

isPCM16Wav tested only the bit depth, and go-audio's IsValidFile never looks at
the format tag, so a 16-bit WAVE_FORMAT_EXTENSIBLE (0xFFFE) upload was passed
through untouched where the old fold would have transcoded it. audio.cpp's WAV
reader accepts 16-bit only when the tag is 1, so such a file died with
"unsupported WAV encoding". Extensible is what many DAWs and Windows tools
write and music files are this endpoint's new headline input, so it is a
first-contact failure rather than a corner. The check now requires tag 1, with a
spec that fails against the old implementation.

Stem URLs are percent-escaped. A stem name is the model's own string and legally
contains a space, a '#', a '?' or a '%'; an unescaped '#' truncates the URL
before the request is even sent. The name field keeps the raw name.

sample_rate and response_format are applied to the stems as well as to dst.
Applying beat documenting: dst IS one of those stems, so leaving them alone
broke the "dst duplicates the selected stem" invariant the whole design rests
on, and both conversions are no-ops when unset. A stem whose conversion fails is
dropped from the header rather than advertised in the wrong shape.

Verifying that turned up why it had never been noticed: the two fields were
never bound at all. The request arrives as multipart/form-data and echo's binder
falls back to the FIELD NAME without a form tag, matching only
case-insensitively, so "SampleRate" never matched "sample_rate" and "Format"
never matched "response_format". Both were documented in the endpoint table and
silently ignored. Two form tags fix it, and with them the conversion is
observable end to end.

Docs: audio-transform.md now documents what LocalAI does to an upload before the
backend sees it, which backend gets the 16 kHz mono fold and why, params[stem],
and the X-Audio-Stems header with a worked example.

Also records the known limitation that the fold lookup is on the bare backend
name, so pinned variants (vulkan-localvqe) do not match, and points at
IsLlamaCppBackend as the suffix-tolerant precedent.

* backend(audio-cpp): serve the TTS and SoundGeneration RPCs

TTSRequest.voice is treated as a speaker reference clip when it names an
existing regular file, which makes routing prefer VoiceCloning, and as a named
preset otherwise, in which case it travels as VoiceReference::cached_voice_id.
Both the clip and SoundGenerationRequest.src are read at the file's own rate and
channel count: upstream's own CLI and server do exactly that, every consuming
family resamples internally and mostly with a better resampler than ours, and
ace_step and stable_audio resample their input per channel, so a downmix here
would delete the stereo image they are built to consume.

The request builders live in their own unit rather than in grpc-server.cpp's
anonymous namespace so they can be tested; grpc-server.cpp has a main() and
cannot be linked into a test binary. The option keys are the whole point of
these functions, so each one was grepped against the pinned upstream and the
accounting is written down beside it. instructions maps to "instruct", which is
what upstream's own server maps the OpenAI field to and what qwen3_tts and
omnivoice read, and to "caption" for irodori_tts; the style tag is spelled
"instruct" too, because "instructions" is looked up nowhere. duration maps to
"duration_seconds", read by all three generation families, with the proto's own
name kept only as a forward-tolerant alias. Keys that no family reads say so.

Both handlers answer a capability refusal before taking the lane and before any
file read, so a model that cannot synthesise does not queue behind somebody
else's run to be told no.

* backend(audio-cpp): stop emitting an empty style language, and name the missing clip

StyleCondition::language was set whenever has_language() was true, with no
!empty() guard, while the language option twelve lines below had one.
core/backend/tts.go sets Language unconditionally, so has_language() is true on
every request LocalAI sends and carries "" when the caller named none. An
engaged-but-empty style language is worse than an absent one: supertonic reads
text_input->language behind its own !empty() guard and then overrides it from
style->language with no guard at all, so "" replaced its "en" default and its
tokenizer threw "invalid Supertonic language: ". Every /v1/audio/speech request
that set instructions and no language would have been an INTERNAL against a
supertonic model. A plain request never saw it, because the style condition only
exists when instructions are non-empty, which is why the chatterbox end to end
run did not catch it.

TTS also stops discarding the Route that check_can_serve already returns. A
family routed to voice cloning without a reference clip used to be refused from
inside its own prepare(), which meant an INTERNAL naming neither the RPC nor the
field to set; chatterbox advertises clon and no tts, so that was every
preset-only request to it. It is now an INVALID_ARGUMENT naming
TTSRequest.voice, answered in about 4 ms, and it cannot misfire because
has_voice_reference is what selected cloning in the first place. Reading
CapabilitySet::supports_speaker_reference to generalise this stays a follow-up.

The src read carries a written caveat rather than a family blocklist, because
ace_step's editing routes legitimately need src: setting src on a stable_audio
model corrupts the heap and aborts the process in the pinned upstream, and the
only thing keeping that off the network is that
schema.ElevenLabsSoundGenerationRequest has no field for it. Nobody reading that
Go schema would know why, so the reason is recorded where the field is read.

build_tts_shape is extracted so TTSStream cannot describe the same request
differently, and it arrived untested: two mutations of it survived until a
test_tts_shape case was added.

* backend(audio-cpp): serve the TTSStream and AudioTranscriptionStream RPCs

TTSStream leads with a streaming WAV header carrying 0xFFFFFFFF sizes, matching
the convention backend/go/vibevoice-cpp established, so an HTTP client can start
playback before the full PCM exists. Its chunks are read from
StreamEvent::named_audio_outputs and not audio_output: supertonic, omnivoice and
voxcpm2 all put their streamed audio there and leave audio_output empty until
the very end, so reading the obvious field yields a stream with no audio in it.
The finish_stream result is the family's own merged whole rather than a tail, so
it is emitted only when nothing was streamed.

Streaming transcription sends incremental deltas and degrades to a single delta
plus the final result on families that offer no streaming ASR, which is the same
message sequence with fewer deltas. The four streaming ASR families disagree on
what partial_text means: nemotron_asr, vibevoice_asr and higgs_audio_stt report
incremental fragments while voxtral_realtime reports the whole hypothesis and
reports it twice, so the reconciliation lives in one tested unit rather than in
the handler. nemotron_asr reports only through the stream event sink, and only
from inside finalize, so the audio driver installs one and clears it again
before returning: the session is cached and a sink left holding the caller's
frame is a use after free waiting for the next stream.

begin_stream is now the only implementation of the streaming state obligation,
prepare then start_stream. Streaming sessions are cached, and what clears the
previous stream is start_stream's reset; a family override that dropped it would
break every call site with no compile error, so there is one call site.

* backend(audio-cpp): keep streaming deltas on UTF-8 boundaries, refuse dtypes that abort

TranscriptStreamResponse.delta is a proto3 string, whose wire format requires
valid UTF-8. voxtral_realtime reports its hypothesis as a concatenation of raw
token BYTES (tokenizer_text.cpp:171-183), so the cumulative difference between
two consecutive reports is eventually a lone continuation byte, and the C++
runtime serializes that with only a logged warning while the Go runtime refuses
to unmarshal it: the client loses the remaining deltas AND the final_result.
Measured on a trace of a non-ASCII sentence, 11 of 31 messages failed to
unmarshal and every accented character was lost. TranscriptDeltaTracker now
holds back an incomplete trailing sequence and merges it into the next fragment;
reconcile flushes it, which it always can because the final text is complete.
The same trace now unmarshals in full with zero failures.

A streaming buffer whose float count is not a whole number of frames is refused
rather than truncated. The integer division dropped the tail floats from the fed
audio and therefore from the transcript, with no diagnostic; vibevoice_asr
refuses the same thing from the other side of the call.

A supertonic GGUF whose weights are not f32 is refused at load. It reaches
ggml_concat with mismatched operand types and ggml_abort takes the whole backend
process down on the first request, so nothing downstream can report it: the
model loads, then every request kills the process. Attributed rather than
assumed, the unary TTS path aborts identically, and upstream records that
package as untested. The refusal names the orig package and says what to run
before deleting the guard.

* backend(audio-cpp): stop a repeated lead byte from orphaning the next delta

The first UTF-8 fix closed the cumulative half only. Rule 2 discards a fragment
the known text already starts with, and when that fragment is the LEAD BYTE of a
new character it looks exactly like a repeat of an older character beginning
with the same byte. It was discarded rather than held, its continuation bytes
then arrived alone and began the next delta, and utf8_complete_prefix_length
only ever inspected the trailing sequence, so a delta invalid at the FRONT went
out whole. Through a real Go proto.Unmarshal the review's four-character repro
gave 3 deltas, 2 unmarshal failures and a lost transcript.

Reachable from the incremental families, not only from voxtral: nemotron_asr's
decoder cuts at a byte offset and vibevoice_asr's common_prefix_size compares
bytes, so both split characters. Measured over 30,000 randomized incremental
traces, 53.28% of Japanese traces and 9.52% of French ones carried at least one
delta the Go runtime refuses.

Two changes. Rule 2 no longer judges a fragment that ends mid-character, so the
lead byte is held instead of swallowed and the character survives intact; the
cost is a few duplicated bytes in a shrinking cumulative report, which no pinned
family produces. release() additionally drops leading orphan continuation bytes,
so no delta can begin mid-character whatever the rules above it decide. Losing a
byte keeps the stream alive; emitting one ends the RPC and takes the
final_result with it.

Post-fix all 60,000 traces produce zero unmarshal failures, and the cumulative
streams plus both pure-ASCII incremental streams are byte-identical to the
previous commit, so nothing changed for the families already working.

The weight-dtype allow list moves to family_gate, where it is stdlib-only and
pinned by a test rather than only by a comment. Two comment citations corrected.

* backend(audio-cpp): read only an exact repeat as a repeat, not any prefix

Rule 2 discarded any partial the known text merely started with. For a cumulative
family that is a duplicate; for an incremental family it is an ordinary short
fragment that happens to coincide with the start of the transcript, and it was
dropped, silently corrupting the text. Pure ASCII, no multi-byte character
anywhere: the fragments "pure ", "ascii ", "trans", "c", "ri", "p", "t" left the
client holding "pure ascii transcrit". Over 5,000 randomized traces per
transcript, 9.50% of pure-ASCII and 29.12% of French traces ended with the client
holding something other than final_result.text, with a 200 and no diagnostic.
Both incremental families emit fragments that small routinely, since nemotron_asr
cuts at a byte offset and vibevoice_asr at a common prefix.

Narrowing rule 2 to an exact repeat drives that to zero on all six transcripts
and changes no cumulative stream at all: 30,000 randomized cumulative traces are
byte-identical to the previous commit.

What rule 2 guarded was established from upstream rather than from its own
comment. The only duplicate any pinned family produces is voxtral_realtime's,
where process_available_stream_chunks feeds each event to the sink from inside
its loop and returns the last of the batch, so that event arrives twice with
byte-equal text. A duplicate is an exact repeat, so equality still covers it. The
case given up is a cumulative report that SHRINKS, which no pinned family can
produce: voxtral decodes a token vector that is only push_back'ed and cleared by
reset(), so within a stream it can only grow.

* backend(audio-cpp): serve the AudioTranscriptionLive RPC

The one bidirectional stream this backend serves. The client sends a
TranscriptLiveConfig, then TranscriptLiveAudio frames; the server acknowledges
with ready, emits deltas as the audio arrives, and sends final_result once the
read side closes. There is no offline fallback: live transcription has to
consume audio incrementally, so a family with no streaming ASR is refused
rather than served a batch run, which is what this RPC's Streaming-only
mode_candidates list already says.

The driver is a new sibling of run_streaming_audio, run_streaming_live, because
the audio does not exist yet: instead of slicing a buffer it pulls frames from
the caller until the read side closes. It installs the same ScopedStreamSink in
the same order, which is not optional, since nemotron_asr returns a bare event
from process_audio_chunk and reports every partial through the sink from inside
finalize(). It buffers the wire's frames up to the family's own preferred window
rather than feeding whatever size the client's audio callback produced, and it
does not call finish_stream at all when no audio arrived, because nemotron_asr
throws "finalize requires streamed audio" and an empty transcript is the
truthful answer to transcribing nothing.

Three things the handler had to get right and one it cannot:

  - The audio contract. A live request carries no samples, but nemotron_asr's
    streaming prepare() throws without an audio contract, and
    build_preparation_request derives it from TaskRequest::audio_input, so that
    field is an EMPTY buffer holding only the rate and the channel count.
  - 16 kHz or a refusal. The families express their spans in their own 16 kHz
    feature domain whatever the input was, and live frames cannot be resampled
    on the way in the way a file can, so an 8 kHz session would return
    timestamps 2x off with a 200. core/backend hardcodes 16000 anyway.
  - A mid-stream Config is refused. backend.proto calls it a decoder reset, but
    deltas already on the wire cannot be retracted, so a reset would leave the
    final text contradicting the transcript the client assembled. Ignoring the
    message would hand a client that believes it reset the decoder a transcript
    that silently continues the audio it thought it discarded.
  - The stale-route identity check cannot run here: TranscriptLiveRequest
    carries no ModelIdentity in either arm of its oneof, so snapshot_for does
    not instantiate for it. snapshot_unchecked's comment now names that as a
    second legitimate class of caller and says the fix is a proto change.

eou and eob stay false. They exist for cache-aware models that emit
end-of-utterance and end-of-backchannel tokens; audio.cpp's StreamEvent has no
equivalent signal, and a client uses eou to decide the speaker yielded the turn,
so a guess inferred from silence cuts people off mid-sentence.

The lane is held for the whole stream, which is as long as the user keeps
talking: the streaming session is stateful and cached, so a concurrent run would
interleave two callers' audio and corrupt both transcripts.

Verified against nemotron_asr over a real connection with a 14 s WAV in
512-sample frames: ready first, 59 incremental deltas with no repeated prefix,
concat(deltas) equal to final_result.text, word timestamps in nanoseconds, eou
and eob false. citrinet_asr answers UNIMPLEMENTED naming the family and listing
asr/offline. A config followed by a close returns an empty final_result rather
than hanging, and a first message that is not a config is INVALID_ARGUMENT. Two
concurrent streams both return the complete transcript.

Two cleanups on lines Task 12 touched, folded in. The DtypeAllowList terminator
is now asserted at compile time: the reported out-of-bounds read did not exist,
the single entry does terminate, but the loops have no other bound and any edit
that widened an entry would walk off the end. And the dtype guard now
short-circuits on "is there a table entry" through a new predicate rather than
on the emptiness of the description string, which would have skipped the check
on an entry with an empty allow list, i.e. on precisely the entry that refuses
every dtype.

* backend(audio-cpp): bound the lane a live stream can hold

AudioTranscriptionLive holds the model's inference lane for the whole stream,
which is correct (the streaming session is stateful and a concurrent run would
interleave two callers' audio) and newly dangerous. Every other RPC holds the
lane across compute, or across a write to a slow reader, and both of those
terminate on their own. A live stream instead blocks in a client-driven read,
and a peer that goes silent WITHOUT closing the stream never terminates
anything: the lane stays taken and every other request against that model queues
behind a client that stopped speaking.

live_watchdog is a one-shot idle timer that ends the stream when no frame has
arrived inside a window. It is standard library only, so it is unit tested
without an engine. gRPC's synchronous Read has no timeout and cannot be given
one, so the only way to unblock it is ServerContext::TryCancel, which decides
the wire status itself: the client sees CANCELLED rather than the
DEADLINE_EXCEEDED the handler returns, the reason is logged, and the lane coming
back is the point. When it fires the read loop throws rather than reporting
end-of-input, so the driver does not go on to finalize a decode nobody is
waiting for.

It is armed only after the lane is taken and disarmed as soon as the read side
closes, and both ends matter. Arming earlier would cover acquire(), which
legitimately blocks while another live stream runs, so a queued caller would be
cancelled for waiting its turn. Disarming later would cover our own decode,
where a window overrun is not a peer going quiet and cancelling would throw away
the transcript the client is waiting for.

The window is the new live_idle_timeout_ms option, 30 s by default, 0 meaning no
limit. core/http/endpoints/openai/realtime.go drives a 300 ms ticker and feeds
every tick that produced new audio while a turn is open, so 30 s of silence is a
hundred ticks that delivered nothing. It is also longer than any pause a speaker
takes mid-utterance, which is the case that must never be cut off, and
backend.proto lets one stream span many utterances, so a client that pauses
longer between them raises the option rather than discovering it.

Two smaller corrections in the same handler:

  - check_can_serve now runs BEFORE the sample rate check.
    pkg/grpc/grpcerrors/errors.go degrades to the file path on UNIMPLEMENTED and
    on nothing else, so a live-incapable model asked at a wrong rate was
    answering INVALID_ARGUMENT and costing the caller its fallback.
  - a negative sample rate is refused instead of silently becoming 16000. Zero
    still means 16000, which is what the proto documents; -1 is malformed rather
    than absent and gets the same refusal every other bad rate gets.

And one thing recorded rather than changed, at the handler: "live" here means
incremental INPUT, not low latency, and with the pinned families it does not yet
mean incremental OUTPUT either. nemotron_asr's process_audio_chunk only appends
to its buffer, so its whole decode and every delta happen inside finalize(),
after the client closes its send side. The policy-window buffering is inert for
that family and matters only for vibevoice_asr and higgs_audio_stt.

Verified on the wire with live_idle_timeout_ms:3000. A silent client acked at
371 ms and was cancelled at 3.371 s; a second live stream opened one second
later received its ack 2.37 s in, i.e. at the instant the first was cancelled,
and then transcribed successfully on the same cached session. Without the
watchdog it would still be waiting. Re-ran the live transcription (ready first,
59 incremental deltas, concat equal to the final text, word timestamps in
nanoseconds, eou and eob false), the citrinet refusal at both a right and a
wrong rate (UNIMPLEMENTED either way now), and Task 12's AudioTranscriptionStream
on nemotron_asr, which is unchanged.

Mutation testing the watchdog found a weakness in its own test: the destructor
test slept past the window inside the watched scope, so a destructor that
DETACHED the thread instead of joining it passed unnoticed. The test now uses a
window longer than the scope, which kills that mutant, and says why.

* backend(audio-cpp): refuse the unsupported RPCs with a reason

AudioEncode, AudioDecode, AudioTransformStream, AudioToAudioStream and
VoiceEmbed have no counterpart in audio.cpp's VoiceTaskKind. Each now returns
UNIMPLEMENTED naming the loaded family, what that family does support, and the
upstream limitation, instead of the generated base class's bare status. The
reasons live in a table in capability_routing.cpp so they are data rather than
literals copied into five handlers, and so a test can assert every one of them.

The five claims this was planned against were re-read at the pinned upstream
e800d435d130dc776baf6f3e6129bb62b1495c89, and one did not hold. "audio.cpp
streams tts and asr only" is false: silero_vad advertises vad with
RunMode::Streaming. The refusal stands on the narrower claim that survives, that
no family advertises streaming for any task AudioTransform routes to, and a test
asserts the refuted wording does not come back.

VoiceEmbed is the one refusal whose request carries a ModelIdentity, so it runs
the #10952 check before answering: a stale route must get NOT_FOUND and the
router's sentinel, not "audio.cpp cannot embed speakers" about a model that is
not loaded here. It cannot use snapshot_for, whose no-model branch would tell
the caller to load a model when no model can help, so it takes the reference
through snapshot_unchecked and checks identity itself. That function's comment
now names three classes of caller instead of two.

The two bidirectional surfaces refuse without reading their stream, verified
with a client that writes a config and eight frames first and gets the status
rather than hanging.

* backend(audio-cpp): correct the vevo2 clause, and assert the absences

Review found a false clause in the AudioToAudioStream refusal. It said s2s is
"offline voice conversion ... which converts one clip into another speaker's
voice", which is true of miocodec and false of vevo2: vevo2's s2s route is
`editing` and only `editing` (default_route_for_task and route_matches_task in
src/models/vevo2/session.cpp), documented as "Edit source speech into new target
text while using the target voice" and requiring --target-text, so it rewrites
what was said. vevo2's voice conversion is its separate vc task. It now reads
"offline clip-to-clip processing against a target voice, declared only by
miocodec (voice conversion) and vevo2 (speech editing)", and a test asserts the
miscast cannot come back. The conclusion is unchanged: neither family converses.

That defect was undetectable on the wire, since vevo2 does not load here, which
is the argument for upstream_absence_ctest.cpp. It links engine_runtime purely
to interrogate make_default_registry() and asserts the five premises the refusal
reasons rest on: no codec task kind, no family advertising spk, no streaming for
sep/vc/svc/s2s, miocodec advertising exactly vc and s2s, and s2s advertised by
exactly miocodec and vevo2. The last two are exact sets, so an addition fails
here rather than leaving a message stale. A positive control proves the registry
is populated and the query works before any absence is believed, and every
assertion has a reproduced negative control. This turns an AUDIO_CPP_VERSION
bump from "remember to re-read five prose paragraphs" into a test failure.

unsupported_surface now switches over UnsupportedRpc with no default label, so
-Wswitch reports a sixth enumerator added without a row at build time; the
runtime bounds guard it replaces is deleted.

The AudioTransformStream reason had a true premise and an overreaching
conclusion: an offline sep family could be buffered into a stream, as other
LocalAI backends do. It now says this backend declines to offer a buffered
offline call in disguise, rather than implying impossibility.

* backend(audio-cpp): make the missing-switch-case diagnostic fatal

unsupported_surface() switches UnsupportedRpc onto the table row that explains
it, with no default label, so -Wswitch reports an enumerator nobody handled. As
a warning that is not enough: adding a sixth enumerator and building the shipping
target gives exit 0, a binary and one warning, and the trailing
`return surfaces[0];` then answers the new RPC with AudioEncode's codec reason.
That is a confident, specific and false statement about audio.cpp on the wire, on
the one code path whose entire job is to be truthful about what this backend
cannot do, and it is worse than the runtime fallback it replaced, which at least
named itself as a bug in this file.

capability_routing.cpp therefore joins loaded_model.cpp on the existing
-Werror=switch pin, whose comment already made this argument for the engine enum.
The comment now covers both files. The pin stays per-file rather than
project-wide because upstream's own ace_step/vae_decoder.cpp has unhandled
-Wswitch cases of its own.

Verified: a sixth enumerator now fails `make grpc-server` with exit 2 and no
binary; appending a 14th VoiceTaskKind upstream still fails loaded_model.cpp, so
the two pins fire independently; both reverted clean.

* backend(audio-cpp): package the backend image

Bundles the dependency closure for the from-scratch image, the dlopened ggml
CPU-variant shared objects that ldd cannot see, and upstream's bundled
silero_vad and marblenet_vad assets so VAD works with no download.

The bundled loader sits in the package ROOT rather than at lib/ld.so. run.sh
execs it, which makes /proc/self/exe name the loader, and this backend has two
consumers of that path: ggml discovers the libggml-cpu-*.so by listing
dirname(/proc/self/exe), and resolve_model_path expands bundled:<name> under the
same directory. Rooting the loader makes the binary, the ggml objects and
assets/ share the one directory all three resolution mechanisms agree on.
llama-cpp's lib/ld.so layout would need assets/ moved into lib/ as well.

The image builds against apt gRPC and protobuf, like Dockerfile.ds4 and unlike
Dockerfile.privacy-filter. The from-source gRPC that install-base-deps.sh and
the base-grpc-* images supply vendors protobuf 26, which pulls abseil into
message_lite.h; with SPM_PROTOBUF_PROVIDER=package that collides with
sentencepiece's vendored mini-abseil and every absl::internal reference becomes
ambiguous. Noble's protobuf 3.21.12 predates the abseil dependency and is the
pair every earlier verification of this backend ran against.

* backend(audio-cpp): exempt the driver libraries from the packaging gate

package.sh already left libcuda.so* and libnvidia-* to the host when copying,
because the driver has to match the kernel module on whatever host runs the
image, but the validation gate had no matching exemption. With BUILD_TYPE=cublas
ggml is static and links CUDA::cuda_driver, so grpc-server carries DT_NEEDED
libcuda.so.1 and the gate would have rejected the very absence the copy loop
created, failing every cublas build in CI. One regex now feeds both.

Building a control for that found a second defect: ld.so --list refuses to trace
an object with an unresolvable dependency at all, exiting 127 without emitting a
per-library line, so the "=> not found" rule was dead code and no exemption could
have applied to it. The gate now traces with LD_TRACE_LOADED_OBJECTS and
LD_LIBRARY_PATH, which reports the missing name and exits 0, and which is also
what run.sh does at run time.

Adds a layout assertion so a future move of the loader into lib/ fails the build
instead of shipping a package that resolves bundled: models into lib/assets and
finds no ggml CPU backend, and records for Task 16 that the Darwin script must
not be a straight copy of privacy-filter-darwin.sh, which never calls package.sh
and would silently drop assets/.

* backend(audio-cpp): register the backend with CI and the gallery

Adds the five Linux matrix entries (cpu amd64/arm64 sharing a tag-suffix so the
manifest merge fires, cuda 12, cuda 13, vulkan), the path-filter case that keeps
later PRs touching backend/cpp/audio-cpp/ from getting zero CI jobs, the
bump-bot entry pointing at the AUDIO_CPP_VERSION pin in the backend Makefile,
the gallery meta plus its -development variant and the image entries for every
variant, and the Makefile docker-build wiring.

The matrix entries carry base-image only, with no builder-base-image, unlike
the llama-cpp and privacy-filter blocks they sit next to. The prebuilt
quay.io/go-skynet/ci-cache:base-grpc-* images ship a from-source gRPC whose
protobuf v26 depends on abseil, and this backend's sentencepiece is built with
SPM_PROTOBUF_PROVIDER=package, so it sees real abseil's absl::lts_20240116::
internal alongside its own vendored plain absl::internal and every
absl::internal:: reference becomes ambiguous. Building against base-grpc-amd64
fails at sentencepiece-static.dir/error.cc.o with "reference to 'internal' is
ambiguous". Dockerfile.audio-cpp installs apt's gRPC/protobuf 3.21.12 itself,
which is also the pair every unit and end-to-end run of this backend has been
verified against, and the CUDA toolkit therefore has to come from base-image.

No Darwin matrix entry and no metal gallery entries: the Metal build needs
scripts/build/audio-cpp-darwin.sh, a backends/audio-cpp-darwin make target and
a routing step in backend_build_darwin.yml, none of which exist yet, so an
entry added now would be routed to build-darwin-go-backend and look for
backend/go/audio-cpp/. The inferBackendPathDarwin case and the
DARWIN_BESPOKE_BUILDERS membership are in place, inert, so that adding the
entry later is a one-line change that cannot be claimed by the generic Go path.

* backend(audio-cpp): pin the CUDA architectures, drop the vulkan variant

Upstream sets CUDA_ARCHITECTURES to `native` on the engine_runtime target
whenever CMAKE_CUDA_ARCHITECTURES is unset at root scope, and docs/build/
linux.md says so outright. ggml's own default does not rescue it: it
list(APPEND)s in the ggml subdirectory scope, which never reaches the root
scope where the engine_runtime property is decided. No CI runner has a GPU for
`native` to enumerate, so both cublas entries would have gone red on the very
commit that first turns a CUDA build on.

Pin the list in backend/cpp/audio-cpp/Makefile, selected by CUDA_MAJOR_VERSION,
which Dockerfile.audio-cpp now forwards from the CI build-arg it was previously
discarding. The values are copied from ggml's own version guards rather than
invented, so engine_runtime and ggml compile for the same set: CUDA 12 keeps the
Maxwell/Pascal/Volta virtual archs and stops at 120a-real, CUDA 13 drops them
and adds 121a-real. The `a` suffix is used rather than `f` because the latter
needs CMake 3.31.8 and Ubuntu Noble ships 3.28.3. Verified by driving CMake
3.28.3's own CUDA architecture validator over both lists, with 120f-virtual as
the rejected control.

Drop the vulkan matrix entry, its two gallery entries, the vulkan capability
key on both metas and the Vulkan tag. Every other vulkan backend gets its Mesa
ICD drivers from .docker/install-base-deps.sh, which package-gpu-libs.sh then
bundles; Dockerfile.audio-cpp calls neither and installs only libvulkan-dev and
glslc, so the image would ship a Vulkan loader that finds no GPU. No CI job runs
a vulkan image against real hardware, so that would have passed green and failed
in users' hands. BUILD_TYPE=vulkan stays supported for local builds.

Also note on the cublas entries that cuda-major-version now selects the
architecture list and that cuda-minor-version and the base-image tag encode the
same toolkit, and correct the stale entry counts on matrixEntryKey.

* backend(audio-cpp): build for Darwin Metal

Bespoke C++ Darwin path like ds4 and privacy-filter: an includeDarwin matrix
entry, a backends/audio-cpp-darwin make target, a gated workflow step, and the
metal image entries plus metal/metal-darwin-arm64 capability keys in the
backend gallery.

The build script deliberately does NOT reassemble the package the way
privacy-filter-darwin.sh does. It runs the backend's own `make package` and
copies the result, so the Darwin package keeps the root-level layout the Linux
one has: grpc-server, run.sh, the ggml objects and assets/ in one directory,
with lib/ for the dylib closure. Hand-assembling would drop assets/, and
assets/ is what makes the bundled: model paths resolve with nothing downloaded.
The dylib walk is a full transitive closure rather than the single level ds4
and llama-cpp do, because Homebrew's grpc++ pulls libgrpc, abseil, upb, cares
and OpenSSL that grpc-server does not link itself, and a level-1 walk ships a
package that only works on a machine that already has Homebrew grpc.

Two fixes folded in, both in the backend Makefile:

  - an EMPTY CUDA_MAJOR_VERSION fell through to the CUDA 12 architecture list,
    which contains 120a-real and so needs nvcc >= 12.8. A local
    BUILD_TYPE=cublas build on a 12.0-12.7 host failed to compile where
    upstream's documented default (native) worked. EMPTY now maps to native,
    12 and 13 keep their lists, and any other non-empty value is an error on
    cublas builds. CI always passes a major, so CI is unaffected.

  - the Darwin branch now points CMake at Homebrew's keg-only libomp. AppleClang
    ships no OpenMP runtime and nothing is symlinked into /opt/homebrew, so
    FindOpenMP finds neither the library nor the header, and audio.cpp calls
    find_package(OpenMP REQUIRED) whenever ENGINE_ENABLE_OPENMP is on. Without
    the hint the macOS build would have died at configure time. If the keg is
    absent the build disables OpenMP instead of failing.

* backend(audio-cpp): make the Darwin fallbacks loud and the rpath walk complete

Review follow-up on the Darwin Metal build.

The OpenMP fallback was silent. If brew --prefix libomp ever comes back empty,
CI produced a green Metal package with 108 #pragma omp directives across ~30
files compiled out, and clang says nothing about an ignored omp pragma without
-Wsource-uses-openmp, so the only trace was one absent flag inside a set -x
cmake line. That regression would have been blamed on Metal. It now warns.

The @rpath arm of the dylib walk had no live candidate when it was written, on
the reasoning that a Metal build links ggml statically. The OpenMP fix in the
same commit made libomp.dylib one, and whether Homebrew records it as an
absolute opt path or as @rpath/libomp.dylib is not observable from Linux. The
walk now expands @rpath, @loader_path and @executable_path against the object's
own LC_RPATH entries, and only fails when nothing on disk answers, printing the
rpath list with the error so a failure on a machine nobody can attach to
explains itself.

Also: ADDITIONAL_LIBS now go through the closure rather than a bare cp, so they
are deduplicated and their own dependencies bundled; build/darwin/lib is
created explicitly instead of relying on package.sh pre-creating it; the libomp
probe uses nested ifneq rather than $(and ...), which needs GNU make 3.81 and
would otherwise expand empty and take the OFF branch on an older make; and
-DOpenMP_ROOT is quoted like its CUDA sibling.

Verified with a Linux harness that runs the script verbatim against a stubbed
otool: a level-2 transitive dep, an @rpath dep reachable only through LC_RPATH,
and an ADDITIONAL_LIBS dep are all bundled, a dependency cycle terminates,
system libraries are skipped, the packaged tree has assets/ at the root beside
grpc-server with the dylibs in lib/, and both failure paths exit non-zero.

* backend(audio-cpp): make bundled: reachable from a model YAML

resolve_model_path() tested the bundled: prefix on `candidate`, which prefers
ModelFile and falls back to Model. LocalAI fills ModelFile by joining ModelPath
onto the configured model string (pkg/model/loader.go, LoadModelWithFile), and
only sets it from a managed artifact otherwise, so a model YAML saying
`model: bundled:silero_vad` arrives as ModelFile "/models/bundled:silero_vad"
and Model "bundled:silero_vad". The prefix therefore never matched through the
normal load path: it matched only for a hand-written LoadModel call that left
ModelFile empty, which is exactly how task 15 verified it, and every model YAML
using the form failed with "model path does not exist:
/models/bundled:silero_vad".

Both fields are now checked, Model first, so the zero-download VAD path the
package ships assets for is reachable the way it is documented. A caller that
puts the form in ModelFile still works, so task 15's verification stands.

Compiled clean; the runtime check could not run on this host, whose system
libprotobuf/libre2 have gone missing (the pre-existing grpc-server binary no
longer resolves its libraries either), so it wants a container run.

* backend(audio-cpp): advertise the backend and document its options

Registers audio-cpp as preference-only in /backends/known: the family lives in
GGUF metadata that an importer cannot read from a remote repo, and one repo
hosts thirty families, so there is no honest auto-detect signal. Modality is a
single string and the import form chips on a fixed key set, so it registers as
tts with the other modalities named in the description rather than under an
invented key the UI would bucket as "other".

Adds a features page covering the option namespacing, the routing table per
endpoint, the RPCs this backend declines and why, the bundled VAD path, the
separation stem behaviour, and the family gotchas (supertonic needs the orig
package; chatterbox advertises cloning and no plain tts; nemotron_asr defers
its whole decode to finalize so live transcription emits nothing until the
client half-closes, unlike higgs_audio_stt and voxtral_realtime). Every option
name and family capability in it was read off the pinned upstream checkout.

* backend(audio-cpp): test resolve_model_path, and correct the family names

The bundled: fix in 842443cd7 shipped without a test, which is how the bug got
there: task 15 verified the form with a hand-written LoadModel that left
ModelFile empty, and that is the one shape the server never produces. Four cases
in streaming_driver_ctest, which already links loaded_model.cpp, pin the
PRODUCTION shapes instead. The first fails against the pre-fix source (returns
the joined /models/bundled:silero_vad); the other three are the branches the
bundled: lookup now runs in front of and must fall through for.

Three family names in the docs were the source directory rather than the
registered family, on pages whose whole argument is that these names cannot be
guessed: demucs is htdemucs (demucs/loader.cpp:22), roformer is
mel_band_roformer (roformer/assets.h:15), and moss is TWO families,
moss_tts_local and moss_tts_nano. The hyphenated ASR names are underscored to
match, here and in the compatibility table.

The supertonic dtype note claimed more than the evidence carries. The f16 abort
is a local observation, identical through TTS and TTSStream; upstream's
docs/gguf.md leaves the 16-bit column untested and records q8_0 as "No
(unsupported weight dtype)", which says unusable rather than fatal. Both are
still refused, because the allow list is what the family can run. Corrected in
family_gate.h, family_gate.cpp and the docs together, since the docs inherited
the wording from the code.

The importers tripwire says in the file that it is a tripwire: it exercises no
audio-cpp behaviour, and the registration assertion lives in backend_test.go.

* gallery: add audio.cpp models covering every served RPC

One representative model per RPC group of the audio-cpp backend, plus the two
bundled VAD models, which need no download at all because the assets ship
inside the backend package.

Every hash was computed with sha256sum on the downloaded file. Quantizations
come from upstream's tested-status table in docs/gguf.md rather than a default
of q8_0: supertonic ships the orig package (its q8_0 is recorded as an
unsupported weight dtype and its f16 aborts in ggml_concat), and nemotron_asr
and htdemucs ship f16 because their q8_0 builds are recorded with drift while
16-bit is a clean pass.

Diarization and separation use the diarization and audio_transform usecases,
not transcript: /v1/audio/diarization and /audio/transform filter the default
model on FLAG_DIARIZATION and FLAG_AUDIO_TRANSFORM respectively, so a
transcript flag would have hidden both models from their own endpoints. The
forced aligner sets parameters.language, which the transcription endpoint uses
as the fallback when no language form field is sent, because the family
requires both a transcript and a language.

All ten entries were run twice: once against the raw gRPC server, and once
installed with local-ai models install and called through the HTTP endpoint.

* gallery: correct the audio.cpp entries' licenses

Swept all ten entries against the real upstream named in audio.cpp's
tools/model_manager.py rather than against the audio.cpp repo's own license.
Three were wrong:

  supertonic   apache-2.0 -> openrail      weights come from
                                           mlx-community/supertonic-3-mlx, and
                                           both it and Supertone/supertonic are
                                           openrail
  citrinet     apache-2.0 -> other         pulled from NGC
                                           nvidia/nemo/stt_en_citrinet_256,
                                           governed by the NGC Terms of Use
  sortformer   other -> cc-by-nc-4.0       nvidia/diar_sortformer_4spk-v1 is
                                           CC BY-NC 4.0, and the gallery already
                                           uses that exact string, so there is no
                                           reason to obscure a non-commercial bar

The license field is one word, so citrinet and sortformer also gained a
sentence saying why they are restricted. The other seven were confirmed
correct against their sources.

Also drops an unverified claim from the nemotron description. It said the
model drives the realtime transcription session; that endpoint actually calls
TranscribeStream, and the live RPC reaches LocalAI only through
realtime_semantic_vad.go. Neither path was exercised here, so the description
now states only the two calls that were.

MarbleNet gains the NeMo upstream under urls: for parity with silero.

No sha256, quantization, usecase or model choice changed.

* fix(audio-transform): bound sample_rate, keep same-named uploads apart

Four defects the whole-branch review found on the Go side, plus two comment
corrections.

sample_rate is a disk-exhaustion hazard. The branch added the `form:` tag that
makes the field bind for the first time, so the resample path went from dead to
live, and utils.AudioResample interpolates the int straight into ffmpeg's -ar
with no bound. Measured with ffmpeg 7: -ar 999999999 on a 0.01 s clip writes
20 MB and exits 0, which scales linearly to the reported 3.9 GB for one second,
into a GeneratedContentDir nothing sweeps, and convertStems repeats it once per
separation stem. Clamped to 8000..192000 in the handler, before the temp dir and
before the model is touched, and rejected with a 400 outside it.

The low end was reported as "a 0-byte file". It is not: -ar 1 writes a 78-byte
header with no audio behind it, whose declared data size still claims 70 bytes,
so go-audio parses it as a 35 SECOND file and a size check does not see it. The
guard therefore compares the declared data chunk against the bytes actually on
disk, and AudioResample now fails rather than returning a WAV carrying nothing.

Both parts of a transform request land in one temp dir, and the raw copy was
named only after the client's basename, so `-F audio=@mic/clip.wav
-F reference=@loopback/clip.wav` wrote "raw-clip.wav" twice. Since
AudioToWavPreservingShape hardlinks an already-PCM16 WAV rather than copying it,
the reference part's os.Create truncated the inode audio.wav pointed at: mic and
reference came out identical, which makes an echo canceller null everything and
return near-silence with a 200. The raw copy now carries the form field name.

audio-cpp had no BackendCapabilities entry, so VoiceCloningForModel returned nil
before it ever consulted the model's tts.voice_cloning override and every
`voice: "profile:<id>"` request was refused with a 400, on a backend that ships
audio-cpp-chatterbox whose family serves cloning and not plain TTS. Registered
with its RPCs, usecases and the reference-audio contract, and deliberately
without the 16 kHz mono fold, which its separation families cannot survive.

GetBackendCapability was exact-match only, so every pinned gallery variant read
as an unknown backend: vulkan-localvqe lost the 16 kHz mono fold that used to be
unconditional and started failing inside LocalVQE, and the usecase gate does not
stand in for it because BuildFilteredFirstAvailableDefaultModel returns early
once the client names a model. Lookup now falls back to the meta name by
stripping the gallery's hardware prefix and release-channel suffix, exact match
first so nothing can be shadowed. Same class as #10945.

Also corrected: the AudioTransformRequest comment claimed echo's binder falls
back to the field name, which it does not in either direction (bindData binds
ONLY tagged fields and `continue`s otherwise; `model` arrives from
setModelNameFromRequest's c.FormValue). And the stable_audio `src` heap
corruption caveat now lives on ElevenLabsSoundGenerationRequest, where the Go
developer who would add the field can see it, instead of only in C++.

* fix(audio-cpp): refuse a task pin the RPC cannot serve, and stop empty frames holding the lane

The model's `task:` option is copied into the request shape by all nine
handlers, which is correct, but resolve_route then replaced the RPC's candidate
list with the pin WHOLESALE and never asked whether the pin was something that
RPC routes to. One pin therefore bled across all nine surfaces, and because the
family still supported the pinned task the result was a wrong 200 rather than an
error. Reproduced live: nemotron with task:asr made Vad return 200 with zero
segments after a full ASR decode, so 14 seconds of speech was reported as
silence, and Diarize did the same; silero_vad with task:vad made
AudioTranscription return 200 with empty text and four segments whose spans were
VAD segments, which combined with response_format in {text,srt,vtt,lrc} building
the body solely from Segments[].Text yields a well formed SRT of four timed
EMPTY cues. It also contradicted the documented contract, that a family which
cannot serve a request is refused rather than rerouted.

A pin is now checked against the RPC's admissible task set before it is adopted,
and the refusal names both the pin and the RPC. The set is derived from
task_candidates with every shape flag set rather than restated, so a task added
to an RPC's candidates cannot become inadmissible by omission. Every legitimate
pin survives, and the test asserts all fifteen of them alongside the eight
crossings that must not.

The live watchdog was defeated by empty frames. idle.touch() ran on ANY message,
before the has_audio and pcm.empty() filters, so a peer writing unset-oneof or
zero-length frames faster than the window held the lane indefinitely while
feeding the decoder nothing. There is one lane per model and one model per
process, so that is a single client denying the whole backend, which is what the
watchdog exists to prevent, and the thrown text already said "no audio frame
arrived". The touch moved below the filters, which are now a named predicate so
the distinction is testable rather than a call order nobody can see.

Three comments corrected against measurement rather than reasoning:

- CMakeLists claimed zero google::protobuf:: definitions remain in the
  executable. nm -C --defined-only reports 2515, and that is expected: they are
  generated code, sentencepiece::ModelProto's own _InternalParse among them. The
  claim that holds, and the one the ABI fix is actually about, is that no
  vendored protobuf RUNTIME is linked and ParseContext::ParseMessage is
  UNDEFINED in the executable, resolving to libprotobuf.so.
- refuse_cloning_without_a_clip's "cannot misfire" paragraph had its reasoning
  backwards. Routing picks VoiceCloning as the FALLBACK when there is no clip,
  which is the case being caught; chatterbox, which ships in the gallery,
  advertises clon and no tts at all, so every voice-less request lands there.
- audio_units read "2.1 min at 96 kHz" for index 11289602, which is 1.96 min.
  2.1 min is 96 kHz's OWN first failure at 12288002. Both were remeasured and
  the note is now a per-rate table.

* build(audio-cpp): exclude the upstream checkout from the C++ gate, harden the darwin walk

run-unit-tests.sh pruned */llama.cpp/* but not */audio.cpp/*. It is safe today
only by luck: upstream's 44 tests all put "test" at the FRONT of the filename
(17 test-*.cpp, 27 test_*.cpp, zero *_test.cpp), so the glob misses every one of
them, and nothing enforces that. This gate runs on every PR for every backend
and compiles each match as a standalone translation unit with nothing but
nlohmann/json on the include path, so the day upstream adds or renames one test
the gate goes red repo-wide on an Apache-2.0 file nobody here wrote.

audio-cpp-darwin.sh now logs the raw otool -L output and the parsed LC_RPATH
list unconditionally, before the walk. Both awk filters in that script assume a
column layout nobody working on this can observe, since it runs only on the CI
Mac, and a green first Darwin run proves nothing about the assumption: an awk
that silently matched nothing yields an empty dependency list, which reads
exactly like "no non-system dependencies" and packages happily. Both filters
otherwise feed process substitutions, so their input never reached the log.

It also lists every symlink in the package and fails on one that cannot resolve
inside the image. A dangling link does not fail anything else here, because
every assertion tests with -e, which follows links; it fails at dlopen on a
user's Mac. Links are NOT banned outright, which the review suggested but which
would break the libggml.dylib -> libggml.0.dylib chain the `cp -a` above exists
to preserve. What is banned is a link that resolves on the build host and will
not resolve in the image: a broken one, or an absolute one pointing outside the
package.

* fix(config): key the voice-cloning model rule on the resolved backend

Making GetBackendCapability strip the gallery hardware prefix and release
channel fixed pinned variants of /audio/transform, but VoiceCloningForModel
kept keying its per-backend switch on the caller's spelling. A pinned name
therefore resolved the capability by stripping and then missed every case in
the switch, falling through to the permissive default: cuda12-vibevoice-cpp
advertised voice cloning for the realtime 0.5B model, metal-coqui for
tacotron2, cuda12-crispasr for a pure ASR model, cpu-qwen3-tts-cpp for
CustomVoice. Each of those is a model that cannot clone, so /v1/audio/speech
accepted a profile: voice it had to fail on inside the backend rather than
rejecting it with a 400, and the UI advertised the capability too.

resolveBackendCapability now returns the key the entry was found under, and
callers that branch on backend identity use that key instead of the name they
were handed. The exact-match-first order is unchanged, so a backend genuinely
registered under a variant-looking name still keys on its own name.

* gallery(audio-cpp): declare audio_transform on the chatterbox entry

Chatterbox advertises VoiceCloning AND VoiceConversion
(src/models/chatterbox), and the entry's own description already said so, but
known_usecases listed only tts. /audio/transform selects its default model by
FLAG_AUDIO_TRANSFORM, so voice conversion was reachable only by naming the
model explicitly and was invisible to every usecase-driven surface. It is the
one audio.cpp task with a shipped gallery model and no way to find it.

Verified against the real model rather than inferred from the capability list:
AudioTransform with chatterbox-q8_0, speech as audio_path and a speaker clip
as reference_path, returns a 5.08 s 24 kHz mono WAV at -25.5 dB mean and zero
stems, which is the single-output shape voice conversion should have.

The description now says which endpoint reaches that half and warns that
installing this next to a source-separation model gives /audio/transform two
candidates, so the model should be named rather than defaulted.

* gallery(audio-cpp): add voice-design and singing-voice-conversion entries

Two of the three audio.cpp task kinds that had no gallery model now have one.
Both were driven end to end against the real weights through the backend
before being written, not inferred from the capability tables.

audio-cpp-irodori-voicedesign covers vdes. TTS carrying `instructions` routes
to the vdes task, so the voice is described in words rather than supplied as a
clip. Verified: "a calm elderly woman speaking slowly with a warm, gentle
tone" over an 8.76 s 48 kHz mono render at -16.8 dB mean, and a closed-loop
citrinet pass recovers the sentence with the accent drift expected from a
Japanese-first model read by an English recogniser.

audio-cpp-seedvc-singing covers svc, and pins task:svc because nothing else
can reach it. seed_vc advertises svc and ordinary voice conversion, no request
signal means "this input is singing", and auto-routing resolves the tie to
voice conversion every time. Verified with the pin: 5.04 s 44.1 kHz output
whose closed-loop citrinet transcription is exact.

s2s deliberately has no entry, and the reason is not effort. miocodec is the
only upstream family whose speech-to-speech route needs no text, and it
returned audio with correct duration and level but no recoverable speech in
four independent attempts: the stale build, v2 q8_0, v2 orig (the variant
upstream records as a clean Pass), both tasks, and matched 44.1 kHz inputs on
both sides. vevo2's route refuses with "Vevo2 text/prosody route requires
text_input or target_text", and session.cpp:897 fills target_text only from
request.text_input, which AudioTransform has no field to carry. The same
vevo2 weights convert voice correctly through the default route with an exact
ASR round trip, so the model and the plumbing are both healthy; it is the s2s
route specifically that this RPC cannot express.

* backend(audio-cpp): carry transform text through params, add the s2s entry

AudioTransform is audio-in / audio-out and its proto message has no text
field, but not every task it routes to is audio-only. vevo2's speech-to-speech
route is a text and prosody route: session.cpp:897 fills refs.target_text from
request.text_input and nowhere else, and the run refuses without one with
"Vevo2 text/prosody route requires text_input or target_text". The params map
is the only channel this RPC has that reaches the engine, so the text travels
through it and apply_transform_text_input unpacks it after the params have
been copied into task.options.

Before this, s2s was not awkward to reach through /audio/transform, it was
unreachable, and it was the last audio.cpp task kind with a real model and no
way to get to it.

target_text is canonical and text is its alias, the order vevo2's own option
table declares them in, so a request setting both gets the canonical one
rather than whichever the map happened to store first. An empty value falls
through to the next candidate instead of ending the search. language rides
along only when a text was found: on its own it conditions nothing, and
manufacturing a text_input for it would route a plain separation request
carrying a language hint through the text path. The keys are left in
task.options rather than erased, because vevo2's loader advertises target_text
as a request option and a family reading it there keeps working.

Nine tests, all confirmed failing on behaviour against a stub that returned
false before the implementation was written. Verified end to end afterwards:
vevo2-q8_0 with task:s2s and params[text] returns a 5.12 s 24 kHz output whose
closed-loop citrinet transcription is exact, and htdemucs separation with no
text param still returns its four stems, with and without params[stem].

audio-cpp-vevo2-speech-to-speech ships that route. Every audio.cpp task kind
with a loadable family now has a gallery entry; spk remains the only gap and
has no family upstream at all.

voice conversion instead. Both are the kind of thing a user only discovers

* fix(audio-cpp): build arm64 with gcc-14 for the armv9.2 SME variants

The arm64 CPU image failed to build:

  cc1: error: invalid feature modifier 'sme' in
       '-march=armv9.2-a+dotprod+fp16+sve+i8mm+sve2+sme'

ggml's CPU_ALL_VARIANTS table includes armv9.2 variants compiled with +sme, and
Ubuntu Noble's default gcc-13 rejects that feature modifier. Every entry in the
table has to compile even though a host only ever dlopens the one its own CPU
supports, so a single unbuildable variant fails the whole image. gcc-14 accepts
it, which is exactly the fix llama-cpp already carries in
.docker/llama-cpp-compile.sh; this is the same problem reached by a different
Dockerfile.

Applied to every arm64 BUILD_TYPE rather than to the CPU one alone, and that
differs from llama-cpp on purpose. llama-cpp needs it only for its pure-CPU
image because its GPU builds run llama-cpp-fallback, which builds no variant
table. This backend's Makefile turns ENGINE_ENABLE_CPU_ALL_VARIANTS on for
every non-Darwin build, GPU included, so an arm64 GPU image would hit the
identical error. The matrix has no arm64 GPU entry today, which is precisely
why gating on an empty BUILD_TYPE would leave the trap armed for whoever adds
the first one.

Richard Palethorpe 12d1f3a697 security(http): refuse redirects on outbound clients via hardened pkg/httpclient (#10087)
LocalAI's outbound HTTP clients used Go's default redirect policy, which
follows up to 10 redirects. On a cross-host redirect Go forwards custom
request headers — including credential headers such as Anthropic's
x-api-key — to the redirect target (Go strips Authorization, Cookie and
WWW-Authenticate cross-host, but NOT arbitrary custom headers). An
attacker able to elicit a redirect from an upstream (a hijacked or
spoofed upstream, DNS trickery, or a malicious upstream_url) then
harvests the operator's provider API key.

This was first reported against the cloud-proxy / MITM PII path
(GHSA-3mj3-57v2-4636); the same class affects every other outbound
client. Rather than patch each call site, add pkg/httpclient as the one
sanctioned constructor for outbound HTTP and route everything through it.

pkg/httpclient:
  - New(...)             refuses redirects, TLS 1.2 floor, no body
                         deadline (streaming/SSE safe)
  - NewWithTimeout(d)    simple request/response calls
  - WithFollowRedirects  opt-in following that still strips credential
                         headers on any cross-host hop; different
                         scheme/host/port == different origin, guarding
                         the curl CVE-2022-27774 port-confusion class
  - WithTransport(rt)    keep a custom transport (IP-pin, HTTP/2, a
                         credential-injecting RoundTripper)
  - HardenedTransport()  base transport with the TLS floor + bounded setup
  - Harden(c)            apply the policy to a library-supplied *http.Client
  - NoRedirect           the CheckRedirect policy; wraps ErrRedirectBlocked

Lint: a forbidigo rule flags http.DefaultClient and http.Get/Post/
PostForm/Head, pointing at pkg/httpclient (.golangci.yml,
.agents/coding-style.md). forbidigo cannot match the &http.Client{}
composite literal without also flagging legitimate *http.Client type
references, so that form is enforced by review.

Migrates every non-test outbound call site across core/, pkg/, cmd/, and
the Go backend (backend/go/cloud-proxy). Credential-bearing and
internal-RPC clients refuse redirects; download / CDN / registry clients
use WithFollowRedirects so they keep working while stripping secrets
cross-host. The only credential-bearing client that follows redirects is
the gated-download path (pkg/downloader/uri.go), which strips the token

  - cors_proxy following redirects, bypassing its SSRF IP-pin
  - downloader's authorized read path leaking the token cross-host

TLoE419 fc2bd0986c test(utils): cover path verification, sanitization, and unique naming (#9978)
pkg/utils/path.go provides the security primitives for download paths
(VerifyPath, InTrustedRoot) and the file-naming helpers used by every
import flow (SanitizeFileName, GenerateUniqueFileName). None of them had
test coverage, so a future regression in the traversal check or in the
".." stripping inside SanitizeFileName would land unnoticed.

The new specs pin the lexical contract for each helper:

- VerifyPath accepts strict descendants and inner traversal that stays
  inside the base, rejects "..", compound traversal, and the base path
  itself. An explicit spec documents that the check is purely lexical
  (filepath.Clean, not EvalSymlinks) so any future caller that needs
  symlink-aware defence knows to EvalSymlinks first.
- InTrustedRoot rejects the trusted root and sibling directories,
  accepts deeply nested descendants.
- SanitizeFileName covers the leading-directory and absolute-prefix
  paths plus the embedded ".." case ("foo..bar" -> "foobar") that the
  Clean+Base layer alone would leave intact.
- GenerateUniqueFileName covers the no-collision, single-collision,
  walk-the-counter, and empty-extension cases using GinkgoT().TempDir()
  so the suite stays hermetic.

  gate on react-ui changes; install with make install-hooks.
- New Go handler tests (settings, branding), hermetic base64 download test.
- fix(ui): model editor reads vram_display (snake_case), so the VRAM estimate

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,
10.0.0.1, 169.254.169.254, metadata.google.internal.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

No behaviour change in the production path.

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

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

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

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

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

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

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

introspection and the captured tokens otherwise outlive the request.
Strip those header values at capture time. Body redaction is left to a
follow-up — the prompts are usually the operator's own and JSON-walking
is invasive.

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

* feat(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.

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

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

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

* test(auth): pin PUT /api/auth/profile field-tampering contract

those fields. Lock that down with a regression test so a future
"let's just c.Bind(&user)" refactor breaks loudly.

UploadToCollectionForUser handed the filename to a vendored backend
without sanitising at all.

Strip to filepath.Base at both boundaries and reject the trivial
unsafe values ("", ".", "..", "/").

* fix(react-ui): validate persisted MCP server entries on load

localStorage is shared across same-origin pages; an XSS that lands once

scheme, header keys/values must be control-char-free. Drop anything

redirect target without validation, so a forged header value of
"//evil.com" turned the SPA-shell redirect helper at /, /browse, and
/browse/* into a 301 to //evil.com/app. The path-strip middleware had
the same shape on its prefix-trailing-slash redirect.

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

exploitable (cookies aren't sent under wildcard CORS), but the
misconfiguration trap is worth closing. Skip the registration and warn.

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

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

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

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

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

no toast, no fetch, no clue. Reproducible by typing fewer than 12
chars on the second password change of a session.

The JS-level length check in handleSubmit already shows a toast and
the server rejects with a structured error, so the HTML5 attribute
was redundant defence anyway. Drop it.

right fix is to stop reaching out to a third-party CDN for fonts on
every page load.

Add @fontsource-variable/geist and @fontsource-variable/geist-mono as
npm deps and import them once at boot. Drop the <link rel="preconnect">

* 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).

feat(backend): Add Sherpa ONNX backend and Omnilingual ASR

Adds a new Go backend wrapping sherpa-onnx via purego (no cgo). Same
approach as opus/stablediffusion-ggml/whisper — a thin C shim
(csrc/shim.c + shim.h → libsherpa-shim.so) wraps the bits purego
can't reach directly: nested struct config writes, result-struct field
reads, and the streaming TTS callback trampoline. The Go side uses
opaque uintptr handles and purego.NewCallback for the TTS callback.

Supports:
- VAD via sherpa-onnx's Silero VAD
- Offline ASR: Whisper, Paraformer, SenseVoice, Omnilingual CTC
- Online/streaming ASR: zipformer transducer with endpoint detection
  (AudioTranscriptionStream emits delta events during decode)
- Offline TTS: VITS (LJS, etc.)
- Streaming TTS: sherpa-onnx's callback API → PCM chunks on a channel,
  prefixed by a streaming WAV header

Gallery entries: omnilingual-0.3b-ctc-q8-sherpa (1600-language offline
ASR), streaming-zipformer-en-sherpa (low-latency streaming ASR),
silero-vad-sherpa, vits-ljs-sherpa.

* fix(localai): accept data URI prefixes with codec/charset params

Browser MediaRecorder produces data URIs like
  data:audio/webm;codecs=opus;base64,...
so the pre-';base64,' section can carry multiple parameter
segments. The `^data:([^;]+);base64,` regex in pkg/utils/base64.go
and core/http/endpoints/localai/audio.go only matched exactly one
segment, so recordings straight from the React UI's live-capture
tab failed the strip and then tripped the base64 decoder on the
leading 'data:' literal, surfacing as
  "invalid audio base64: illegal base64 data at input byte 4"

Widened both regexes to `^data:[^,]+?;base64,` so any number of
';param=value' segments between the mime type and ';base64,' are
tolerated. Added a regression test covering the MediaRecorder
shape.

* fix(insightface): scope pack ONNX loading to known manifests

LocalAI's gallery extracts buffalo_* zips flat into the models
directory, which inevitably mixes with ONNX files from other
backends (opencv face engine, MiniFASNet antispoof, WeSpeaker
voice embedding) and older buffalo pack installs. Feeding those
foreign files into insightface's model_zoo.get_model() blows up
inside the router -- it assumes a 4-D NCHW input and indexes
`input_shape[2]` on tensors that aren't shaped like a face model,
raising IndexError mid-load and leaving the backend unusable.

The router's dispatch isn't amenable to per-file try/except alone
(first-file-wins picks det_10g.onnx from buffalo_l even when the
user asked for buffalo_sc -- alphabetical order happens to favour
the wrong pack). Instead, ship an explicit manifest of the
upstream v0.7 pack contents and scope the glob to that when the
requested pack is known. The manifest is small and stable; future
packs can be added alongside or fall through to the tolerance
loop, which also swallows any remaining IndexError / ValueError
from foreign files with a clear `[insightface] skipped` stderr

* fix(speaker-recognition): extract FBank features for rank-3 ONNX encoders

Pre-exported speaker-encoder ONNX graphs come in two shapes:

  rank-2  [batch, samples]           -- some 3D-Speaker exports,
                                        take raw waveform directly.
  rank-3  [batch, frames, n_mels]    -- WeSpeaker and most Kaldi-
                                        lineage encoders, expect
                                        pre-computed Kaldi FBank.

OnnxDirectEngine unconditionally fed `audio.reshape(1, -1)` --
correct for rank-2, IndexError-on-input_shape[3] on rank-3, which
surfaced to the UI as
  "Invalid rank for input: feats Got: 2 Expected: 3"

Detect the input rank at session init and run Kaldi FBank
(80-dim, 25ms/10ms frames, dither=0.0, per-utterance CMN) before
the forward pass when rank>=3. All knobs are configurable via
backend options for encoders that deviate from defaults.

torchaudio.compliance.kaldi is already in the backend's
requirements (SpeechBrain pulls torchaudio in), so no new
dependency.

* fix(biometrics): isolate face and voice vector stores

Face (ArcFace, 512-D) and voice (ECAPA-TDNN 192-D / WeSpeaker
256-D) biometric embeddings were colliding inside a single
in-memory local-store instance. Enrolling one after the other
failed with
  "Try to add key with length N when existing length is M"
because local-store correctly refuses to mix dimensions in one
keyspace.

The registries were constructed with `storeName=""`, which in
StoreBackend() is just a WithModel() call. But ModelLoader's
cache is keyed on `modelID`, not `model` -- so both registries
collapsed to the same `modelID=""` slot and reused the same
backend process despite looking isolated on paper.

Three complementary fixes:

  1. application.go -- give each registry a distinct default
     namespace ("localai-face-biometrics" /
     "localai-voice-biometrics"). The comment claimed
     isolation, now it's actually enforced.

  2. stores.go -- pass the storeName as both WithModelID and
     WithModel so the ModelLoader cache key separates
     namespaces and the loader spawns distinct processes.

  3. local-store/store.go -- drop the Load() `opts.Model != ""`
     guard. It was there to prevent generic model-loading loops
     from picking up local-store by accident, but that auto-load
     path is being retired; the guard now just blocks legitimate
     namespace isolation. opts.Model is treated as a tag; the
     per-tuple process isolation upstream handles discrimination.

* fix(gallery): stale-file cleanup and upgrade-tmp directory safety

Two related robustness fixes for backend install/upgrade:

pkg/downloader/uri.go
  OCI downloads passed through
      if filepath.Ext(filePath) != "" ...
          filePath = filepath.Dir(filePath)
  which was intended to redirect file-shaped download targets
  into their parent directory for OCI extraction. The heuristic
  misfires on directory-shaped paths with a dot-suffix --
  gallery.UpgradeBackend uses
      tmpPath = "<backendsPath>/<name>.upgrade-tmp"
  and Go's filepath.Ext treats ".upgrade-tmp" as an extension.
  The rewrite landed the extraction at "<backendsPath>/", which
  then **overwrote the real install** (backends/<name>/) with a
  flat-layout file and left a stray run.sh at the top level. The
  tmp dir itself stayed empty, so the validation step that
  checked "<tmpPath>/run.sh" predictably failed with
      "upgrade validation failed: run.sh not found in new backend"
  Every manual upgrade silently corrupted the backends tree this
  way. Guard the rewrite behind "target isn't already an existing
  directory" -- InstallBackend / UpgradeBackend both pre-create
  the target as a directory, so they get the correct behaviour;
  existing file-path callers with a genuine dot-extension still
  get the parent redirect.

core/gallery/backends.go
  InstallBackend's MkdirAll returned ENOTDIR when something at
  the target path was already a file (legacy dev builds dropped
  golang backend binaries directly at `<backendsPath>/<name>`
  instead of nesting them under their own subdir). That
  permanently blocked reinstall and upgrade for anyone carrying
  that state, since every retry hit the same error. Detect a
  pre-existing non-directory, warn, and remove it before the
  MkdirAll so the fresh install can write the correct nested
  layout with metadata.json + run.sh.

* fix(galleryop): refresh upgrade cache after backend ops

UpgradeChecker caches the last upgrade-check result and only
refreshes on the 6-hour tick or after an auto-upgrade cycle.
Manual upgrades (POST /api/backends/upgrade/:name) go through
the async galleryop worker, which completes the upgrade
correctly but never tells UpgradeChecker to re-check -- so
/api/backends/upgrades continued to list a just-upgraded backend
as upgradeable, indistinguishable from a failed upgrade, for up
to six hours.

Add an optional `OnBackendOpCompleted func()` hook on
GalleryService that fires after every successful install /
upgrade / delete on the backend channel (async, so a slow
callback doesn't stall the queue). startup.go wires it to
UpgradeChecker.TriggerCheck after both services exist. Result:
the upgrade banner clears within milliseconds of the worker
finishing.

* build: prepend GOPATH/bin to PATH for protogen-go

install-go-tools runs `go install` for protoc-gen-go and
protoc-gen-go-grpc, which writes them into `go env GOPATH`/bin.
That directory isn't on every dev's PATH, and protoc resolves
its code-gen plugins via PATH, so the immediately-following
protoc invocation fails with
  "protoc-gen-go: program not found"
which in turn blocks `make build` and any
`make backends/%` target that depends on build.

Prepend `go env GOPATH`/bin to PATH for the protoc invocation
so the freshly-installed plugins are found without requiring a
shell-profile change.

Assisted-by: Claude:Opus 4.7

* refactor(ui-api): non-blocking backend upgrade handler with opcache

POST /api/backends/upgrade/:name used to send the ManagementOp
directly onto the unbuffered BackendGalleryChannel, which blocked
the HTTP request whenever the galleryop worker was busy with a
prior operation. The op also didn't show up in /api/operations,
so the Backends UI couldn't reflect upgrade progress on the
affected row.

Register the op in opcache immediately, wrap it in a cancellable
context, store the cancellation function on the GalleryService,
and push onto the channel from a goroutine so the handler
returns right away. Response gains a `jobID` field and a
`message` string so clients have a consistent handle regardless
of whether the op is queued or running.

Pairs with the OnBackendOpCompleted hook added in the galleryop
commit — together the UI sees the upgrade start, watches
progress via /api/operations, and drops the "upgradeable" flag
the moment the worker finishes.

Ettore Di Giacinto fdb45153fe feat(llama.cpp): Totally decentralized, private, distributed, p2p inference (#2343)
* feat(llama.cpp): Enable decentralized, distributed inference

As https://github.com/mudler/LocalAI/pull/2324 introduced distributed inferencing thanks to
@rgerganov implementation in https://github.com/ggerganov/llama.cpp/pull/6829 in upstream llama.cpp, now
it is possible to distribute the workload to remote llama.cpp gRPC server.

This changeset now uses mudler/edgevpn to establish a secure, distributed network between the nodes using a shared token.
The token is generated automatically when starting the server with the `--p2p` flag, and can be used by starting the workers
with `local-ai worker p2p-llama-cpp-rpc` by passing the token via environment variable (TOKEN) or with args (--token).

As per how mudler/edgevpn works, a network is established between the server and the workers with dht and mdns discovery protocols,
the llama.cpp rpc server is automatically started and exposed to the underlying p2p network so the API server can connect on.

When the HTTP server is started, it will discover the workers in the network and automatically create the port-forwards to the service locally.
Then llama.cpp is configured to use the services.

This feature is behind the "p2p" GO_FLAGS
