Replace standalone Studio wording with Unsloth (#7221)
* Replace standalone Studio wording with Unsloth

Replace the single word Studio with Unsloth wherever it is used as
shorthand for Unsloth Studio in docs, CLI output, UI strings, i18n
locales, workflow display names, comments and docstrings.

Kept unchanged: the full name Unsloth Studio, third party product
names (LM Studio, Visual Studio, Mac Studio), feature names
(Recipe Studio, Fine-tuning Studio and its translations), and all
identifiers such as env vars, commands, paths and filenames.

* Address review feedback on the Studio wording rename

Use "an" before Unsloth where the rename left the article as "a".
Restore the split brand where Unsloth and Studio render as two halves
of the full product name: the onboarding sidebar subtitle and the
IPv6 localhost warning. Scope two messages to the full name Unsloth
Studio where plain Unsloth was misleading: the AMD README bullet and
the CLI studio setup error.

07ccf2b233 install: reconcile branch internals with the repo test suite
Cross-platform staging CI surfaced five Repo tests (CPU) failures where
main's tests assert on script internals this branch legitimately
changed; each reconciled on its merits.

The WoA native-wheel probe still used uv's deprecated --index-url alias
that main's test suite now forbids in favor of --default-index (same
semantics, and --default-index is what overrides inherited uv index
defaults); the probe now matches the convention.

The CUDA provision gate spelled its linked-dir guard with the
:-false default form that main's prune-refactor test blacklists
file-wide. The variable is unconditionally initialized far above, so the
guard now uses the plain spelling with identical semantics. The variable
guard itself stays: unlike a symlink test, it also covers the
canonical-location reuse case where the linked dir is not a symlink.

The gpu-detection tests extract named shell functions into a sandbox,
so _setup_has_usable_nvidia_gpu's new _resolve_nvsmi dependency made the
sandboxed helper die on command-not-found and report not_usable for
usable cases; the extraction list now includes the resolver, and the
driver-version hardening assertion tracks the resolved-path spelling
while still requiring the timeout wrapper. Also hardened the resolver
assignment with an explicit empty fallback so a future non-condition
call site cannot trip set -e.

The staging run also showed the Mac Studio Update uninstall step dying
mid-run, consistent with the round-seven group kill signalling its own
process group; the round-eight self-pgid guard already fixes that and
this push carries it to CI.

Verified: the five failing tests pass locally at this head (the one
remaining local red, test_negative_control_no_tokenizers, fails
identically with these changes stashed and did not fail in CI), bash -n,
PowerShell AST parse, and the sh battery matches the branch baseline.

Stabilize Studio regression tests (#7192)
* Stabilize Studio regression tests

Rebuild on current main. Restore the set-membership sidebar account-block matcher
(#6647, which fixed the same order-sensitive regex, was reverted on main, so the
guard is failing on main again) and keep the watchdog replacement-race fix, whose
blocked-watchdog stub now waits without a timeout so a superseded watchdog stays
alive until cleanup regardless of scheduler load.

* Tighten the blocked-watchdog stub comment

Feat/model picker per model config (#6647)
* refactor(studio): move chat model picker into features/model-picker

Relocate model-selector + its support files from components/assistant-ui
into a self-contained features/model-picker feature (own barrel), mirroring
the modular Hub layout. Pure move + import repoint; no behaviour change.

* feat(model-picker): add per-model config persistence layer

Superset PerModelConfig (customContextLength, kvCacheDtype, speculativeType,
specDraftNMax, tensorParallel, chatTemplateOverride, trustRemoteCode) persisted
to localStorage (unsloth_model_configs) with schema versioning + LRU budget.
KV-dtype and speculative value sets match main's sidebar (no q4_0/ngram-simple).
Reuses features/hub/lib/model-identity for normalization; adds storage-key layer
and applyPerModelConfigToRuntime (sets tensorParallel, which the old PR omitted).

* feat(picker): modular backend for chat-template validate + default fetch

New studio/backend/picker package (schemas/service/routes) mounted at /api/picker:
- POST /api/picker/validate-chat-template (Jinja syntax validation, no false positives)
- GET  /api/picker/chat-template/{model_name} (default template from tokenizer_config.json,
  reusing get_cache_path/resolve_cached_repo_id_case; graceful null, no model-code exec)
Frontend api/templates.ts client + hooks/use-model-defaults lazy cache. No backend
changes to the existing inference load route (per-model load fields already supported).

* feat(model-picker): bind picker on-device list to shared hub inventory

Picker now sources cached + local models from useHubInventory (the Hub's shared
store) via a thin adapter, replacing its own /api/models/* fetchers + module
caches. Hub, download manager, and picker now share one source of truth, so
completed downloads reflect in the picker automatically. Partial/live-download
rows are filtered from the cached lists (unchanged rendering). Local naming/search
preserved via additive LocalInventoryRow modelId/displayName. Variant expander,
scan-folder management, recommended-fit, search, external providers untouched.

Known minor: cached 'Downloaded date' sort tiebreak degrades to alphabetical
(hub cached rows carry no mtime); default 'recent' (load-time) sort preserved.

* feat(model-picker): per-model config step inside the picker

Picking a (non-external) model now opens an in-picker config view built from
main's current load controls (context length, KV cache dtype, speculative
decoding, draft tokens, tensor parallel) plus a chat-template editor backed by
the picker validate/default endpoints. 'Remember for this model' persists the
config per model+variant; Run forwards the config to the existing load flow via
meta.config. External models bypass the step. Two-view orchestration lives in
model-selector (single interception point); pickers.tsx call sites untouched.
trustRemoteCode dropped from PerModelConfig to preserve main's per-load consent.

* feat(chat): apply/persist per-model config through the load flow

handleCheckpointChange threads meta.config into the selection; stageOrLoad and
the autoload/Hub-run paths now apply the picker config (explicit pick or saved
remembered config) via applyPerModelConfigToRuntime before staging/loading, with
keepSpeculative set so a remembered speculative mode survives the model switch.
Replaces the old remembered-load-settings seeding (resolveInitialConfig now the
single source). SelectedModelInput carries config.

* refactor(chat): remove per-model load config from the right sidebar

The load knobs (context, KV cache, speculative, draft tokens, tensor parallel)
and the chat-template editor now live only in the picker config step. The sheet's
Model section keeps the staged Load/Cancel flow (config is applied at pick time);
sampling params, system prompt, and RAG are unchanged. Deletes the superseded
remembered-load-settings module + the store's applyRememberedLoadSettings action,
removes the now-dead sheet state/imports, and points the settings reset at
unsloth_model_configs. Delete-cleanup deferred (stale config is LRU-capped).

* fix(model-picker): remove leftover sidebar-staging cogwheel + empty Model section

The downloaded-variant gear (ModelLoadSettingsAction) staged a model straight
into the right-sidebar Run-settings flow -- the old 'configure before load' path
now fully replaced by the in-picker config step. Removed the gear + its component.
Also gate the sheet's 'Model' section to staged picks only (pendingSelection):
after the load-knob strip its content is staged-only, so it was rendering an
empty section header whenever a model was merely loaded.

* chore(chat): remove dead per-model-config setters + modelControlsDisabled

After the load-config UI moved into the picker, the store's per-model setters
(setKvCacheDtype/setSpeculativeType/setSpecDraftNMax/setTensorParallel/
setCustomContextLength/setChatTemplateOverride) had zero callers
(applyPerModelConfigToRuntime writes via setState), and the sheet's
modelControlsDisabled was unreferenced. Verified dead across the whole tree.

* fix(chat): config-step Load actually loads (ignore Load-on-selection)

Root cause: with Settings > Chat > 'Load on selection' turned OFF, the config
step's load went down the deferred-staging path -- opening the right sidebar with
'<model> is staged, not loaded yet / Choose Load model'. The in-picker config step
IS the deliberate load action, so its Load now loads immediately (or downloads +
auto-loads when not cached) regardless of the toggle. Renamed the button
'Run model' -> 'Load model' to match. Native/dropped picks still honor the toggle.

* refactor(chat,hub): retire 'Load on selection' — config step is the only load flow

The in-picker config step (and the Hub Run button) now fully supersede the old
stage-to-sidebar flow, so the Load-on-selection toggle is removed everywhere:
- chat stageOrLoad: every pick loads immediately, or downloads + auto-loads when
  not cached (the previous default behaviour, now universal).
- hub Run: drops the stage branch; downloaded GGUFs load directly with their saved
  per-model config (no collision with the chat config step — both end at selectModel).
- store: removed loadOnSelection field/setter/key/default; Settings>Chat toggle and
  its settings-reset entry removed.
- staged sidebar section is now a download-progress view (auto-loads on completion).
No manual staging remains; stageModel is used only for background auto-load downloads.

* feat(model-picker): default chat template from GGUF + thread variant through config flow

Read the embedded tokenizer.chat_template from GGUF files (read_gguf_chat_template
in gguf_metadata) and use it as the per-model default. Plumb gguf_variant through
the picker service, /api/picker/chat-template route, frontend templates API, and
use-model-defaults so the right variant's template is fetched.

Also refine the picker config-page/model-selector wiring, drop the dead
ggufNativeContextLength runtime path, and add the per-model-config storage keys to
the settings prefs export.

* feat(model-picker): read safetensors chat template + hide editor where it has no effect

Resolve the default chat template for safetensors models: prefer the modern
chat_template.jinja, fall back to the tokenizer_config.json chat_template field,
then chat_template.json (multimodal processor), then the GGUF embedded template.
Applied to local dirs, the HF cache snapshot scan, and the HF remote fetch.

Hide the chat-template editor in the picker for safetensors models — the override
is only applied at load by the GGUF/llama.cpp backend, so editing it on safetensors
currently has no effect. GGUF keeps the editor. Nothing removed; the dialog stays
for when the safetensors apply path is wired up in a later branch.

* fix(model-picker): set legacy-migration flag only after the write succeeds

Set unsloth_model_configs_migrated only once writeMap confirms the migrated
map persisted, so a quota/storage failure no longer marks migration done and
silently drops the user's pre-existing remembered settings — the next load retries.

* fix(studio): harden model picker config loading

* Fix model picker config flow

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Avoid recursive per-model config migration reads

* Apply the displayed context length when loading a GGUF

* Fix template validation, cached template lookup, and failed load rollback

- Validate chat templates with the loopcontrols extension so templates
  that use break or continue tags pass the picker validator, matching the
  inference renderer that already accepts them.
- Read the default chat template from the newest cache snapshot rather than
  an arbitrary iterdir order, so an older cached revision no longer prefills
  a stale template.
- Capture the runtime per-model config before a load and reapply it when the
  load fails, so a failed switch leaves the active model context, KV cache,
  template, and speculative settings as they were.

* Make chat template view only for safetensors models

Custom chat template overrides are applied at inference only for GGUF
models, which pass the template to llama-server. The safetensors backend
renders with the model built-in template and ignores the override, so
editing it would save a value that never loads. For safetensors the
config page now opens the template as a read-only preview with a note
that editing is not available yet. This can become editable once
inference support for custom safetensors templates lands in main.

* Fix model picker config edge cases

- Restore prior runtime config when a load no-ops for the active model
- Cap the picker validator request body via the protected prefixes
- Keep the GGUF context slider max above the loaded context
- Fetch subfolder chat templates for uncached Hub repos
- Show the compare side config when reopening the picker

* Keep saved GGUF context above the fallback ceiling

* Show the model config in the run settings sidebar

* Fix model config sidebar reset and context slider

- Stack the remember toggle and action buttons in the sidebar
- Reset the config to defaults instead of the loaded values
- Fetch the native context so the slider max is not the loaded value

* Fix model picker config and download regressions

- Run picker chat template routes off the event loop
- Depth and root guard local template directory scans
- Restore download manager flow for uncached hub picks
- Apply per model context length on reload
- Import model picker symbols from the feature barrel

* Fix model picker config and cached download sorting

- Restore load settings when a Hub run is rejected mid load
- Reuse one NumericValueInput instead of a duplicate copy
- Fix double decode of the model name in the template route
- Remove the unused reset-to-loaded settings action
- Fix cached model download sorting

* Fix model picker per-model config edge cases

Honor a saved or typed max seq length above the model's native context so
RoPE extended values are no longer clamped and silently overwritten. Allow
typing past native while the slider keeps native as a soft ceiling.

Guard the fetch success paths in use-model-defaults against an aborted
signal, and refetch when the HF token changes.

Hash the chat template content in the sidebar remount key instead of its
length. Enable reset for a GGUF whose native context is unknown, and floor
the context slider max so it can never fall below the min.

* Fix GGUF context auto-fit and gated model config token

Stop forcing a 32768 context when a GGUF native context is unknown so the backend auto-fits to VRAM again, while still honoring an explicit context edit.

Send the HF token as a query param so gated safetensors models resolve their max position embeddings.

Derive model default state during render to drop the set-state-in-effect calls.

* Fix native GGUF context ceiling and guard picker template reads

Restore the native context store field so the sidebar slider keeps the
full ceiling for drag and drop GGUFs. Limit local chat template reads to
the browse allowlist, skip malformed repo ids, and drop unused model
picker exports.

* Fix model picker lint boundaries

* Fix model picker review findings

Chat template editor never seeded its draft. Radix only calls onOpenChange
from internal events, so the seed in the nextOpen branch was dead and a model
with a saved override opened empty. Saving then cleared the override. Drop the
dead branch, treat draft as an untouched sentinel, and reset it on every close.

Uncached Hub picks could auto load a model after the user left the chat. Main
detached the staged pick on route exit and on chat context change. Carry the
context key on the pending pick and skip the load when it no longer matches.

Also clear configTarget when the picker closes, restore the onUpdated ref so
variant rows stop resubscribing on every parent render, skip the LRU write when
the entry is already most recent, import NumericValueInput relatively, and drop
the unused ModelUpdateAction barrel export.

* Preserve GGUF context on active reload

* Fix model picker per-model config regressions

- Stop reloading the already loaded model on re-pick
- Hide infra models from the chat picker
- Detect vision support on cached GGUF repos
- Honor saved maxSeqLength on auto load
- Restore default chat template for local GGUFs
- Warn on save failure and revert config on cancel
- Refetch picker inventory on open
- Persist read only per model config safely

* Fix stale model auto load

* Fix model picker numeric input sizing and constraints

Size value inputs to their content so long context lengths are not clipped,
restrict them to numeric characters, and stop the speculative decoding label
from truncating in the sidebar.

* Fix picker CI tests and harden chat template resolution for PR #6647

- tests: point the descender guard at the moved model-selector.tsx path
- tests: exclude the disabled Reload model button from the regenerate locator so .first targets the real Regenerate
- picker/service.py: reject symlinked template/gguf leaves that resolve outside the browse allowlist (HF cache reads unchanged)
- compare mode: resolve each pane's own remembered chat template instead of inheriting the other pane's from the store

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Protect future-schema per-model configs from deletion for PR #6647

savePerModelConfig already refuses to overwrite a stored config whose schema version is newer than this client understands, but deletePerModelConfig did not. Unchecking Remember on an older client therefore silently destroyed a newer client's saved config. Apply the same guard on delete and surface the blocked case through the existing saveFailed toast.

* Protect future-schema per-model configs from quota eviction for PR #6647

The save and delete guards already refuse to touch a stored config whose schema version is newer than this client understands, but the quota-eviction path did not, so a full store on an older client could still evict a newer client's config. Skip future-schema entries when evicting and fail the save if the budget cannot be met without them.

* Fix GGUF context persistence, compare context, and rollback settings for PR #6647

Persist a GGUF context override from the user's intent instead of collapsing it against the loaded context, which reintroduced the context-reset (f4838782cb reverted the native-baseline fix). model-config-page now collapses the saved value against native, and use-chat-model-runtime and chat-adapter retain the requested context on load so re-saving another setting keeps the override; a null request stays null so a VRAM auto-fit never becomes a stored override.

shared-composer: a compare pane with no explicit GGUF context now loads at native (0) like single-view, not the session maxSeqLength that silently shrank the shown context.

use-chat-model-runtime: restore the previous model's KV cache dtype and chat template on a failed-load rollback so it runs as it was, not with backend defaults.

* Preserve native path token when reloading the active model for PR #6647

handleReloadActiveModel rebuilt the selection without the store's activeNativePathToken, so reloading a file-picked GGUF after a settings change validated the display label as a repo/path and failed. Thread the active native token through the reload selection so native-loaded models reopen correctly.

* Make picker template validation resilient and accept HF generation tags for PR #6647

Import Jinja lazily inside validate_chat_template so a backend without the optional jinja2 package (GGUF-only installs) still starts instead of raising ModuleNotFoundError at import time. Register a no-op extension for the Transformers {% generation %} assistant-mask tag so pasting a valid HF chat template validates, matching the renderer, rather than being rejected as an unknown tag.

* Honor remembered compare config and parse processor chat_template.json for PR #6647

* Fix failed-load rollback context and processor template map fallback for PR #6647

* Restore speculative decoding config on failed-switch rollback

When a model switch fails after the previous model was unloaded, the
rollback reload restored tensor_parallel, KV cache dtype and the chat
template override, but omitted speculative_type and spec_draft_n_max and
cleared their loaded shadows to null. The previous model therefore came
back running at backend defaults (speculation off) while the UI still
showed it enabled, and the status resync confirmed the off state. Resend
the previous model's speculative settings in the rollback load and keep
the store's active and loaded speculative fields in sync with them.

* Reset max sequence length when a model has no saved config

applyPerModelConfigToRuntime reset every per-model field except
maxSeqLength, which it only wrote when the incoming config had one.
maxSeqLength is the sole field carried on store.params, so selecting a
model with no remembered config left the previous model's value in place
and later loaded the new model at that leaked length. Fall back to the
standing default so an unremembered model loads at its own default.

* Surface a message when a variant update cannot start

startManagedUpdate handled the conflict and error start outcomes but let
busy fall through as if the update began, so the confirm dialog closed
with no job created and the cached variant stayed stale. Show an info
message when the repo is busy with a sibling transfer so the click is
not silently dropped.

* Keep per-model speculative choices out of the global default

A staged load with a per-model or one-off config sets keepSpeculative,
which already skips reading the global speculative preference. The
matching save still ran unconditionally, so the model-specific choice was
written to the global unsloth_chat_speculative_type and a later model with
no saved config started from it instead of Auto. Skip saveSpeculativeType
when keepSpeculative so the per-model choice stays isolated.

* Seed non-active model settings from the app default max length

The Run settings page captured initialMaxSeqLength from the loaded
model's runtime params and fell back to it for a model with no saved
config. Opening settings for a different, unloaded model and clicking
Load then sent the active model's context (for example 64k) instead of
the 4096 default, risking validation failures or OOMs. Seed the default
for non-active models and keep the runtime value only for the active one.

* Prefer sidecar tokenizer chat template over the GGUF copy for variants

_chat_template_from_dir returned the embedded GGUF template first when a
variant was selected, reversing the tokenizer-first precedence of the
no-variant path. A model whose chat_template.jinja or tokenizer_config.json
supersedes a stale embedded template then got the wrong template on
variant selection. Keep tokenizer files first regardless of variant; the
variant only picks which GGUF is the fallback. Adds regression tests for
both the tokenizer-wins and gguf-fallback cases.

* Keep per-model speculative choices load-local in autoload and compare

The interactive load path treats a per-model speculative choice as
load-local and skips writing it to the global default. Autoload and
generalized compare still called saveSpeculativeType unconditionally, so a
remembered off or ngram setting leaked into unsloth_chat_speculative_type
and later models with no saved config inherited it. Persist the global
preference only when the value came from the global settings.

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Studio: record the compare pane's loaded context in runtime state so the active model's settings and any reload or save use it, not the previous context

* Studio: notify the user when a Hub autoload can't start because another download for the model is already running, instead of silently dropping it

* Studio: drop the merge's orphaned staged-model store helpers and unused alert imports

The main merge left isPendingGguf and pendingSelectionMatches referencing the
removed PendingModelSelection type, and the alert-dialog/alert imports unused
after the permission-mode dropdown replaced the bypass dialog, so tsc -b failed.

* Studio: cache a null default chat template so the viewer stops re-fetching it

A model with no sidecar or embedded template resolves to a terminal null, but
that result was never cached, so reopening the template viewer re-ran the
backend and Hugging Face lookup every time.

* Studio: detect direct-file GGUFs in run settings so Max Tokens uses their context

A GGUF loaded from a local file or custom folder has no variant label, so the
run-settings panel treated it as non-GGUF and clamped Max Tokens to the session
max_seq_length instead of the loaded GGUF context. Detect it via the reported
GGUF context and the .gguf checkpoint suffix, matching the chat page.

* Studio: prompt to re-select a local model file when its lease expired before reload

A file-picked GGUF is reachable only through a native path token that the
desktop host prunes after a TTL. Reloading reused that token blindly, so a
reload long after the initial load failed with an opaque error. Track the
token's expiry and, when it has passed, ask the user to re-select the file
instead of attempting a doomed reload.

* Fix descender-clipping test to tolerate sidebar layout utilities

The sidebar account-block div carries layout utilities (min-w-0, flex-1)
between 'flex' and 'flex-col', so the descender-clipping guard's regex,
which required 'flex' immediately followed by 'flex-col', no longer matched
and the test failed to locate the account-block div. Generalize the prefix
to allow intervening flex utilities while still capturing the leading-*
class before the collapsible visibility utility and asserting leading-tight,
so the guard against clipped glyph descenders is fully preserved.

* Harden picker chat-template resolution

Enforce the 64 KiB chat-template contract at the validate endpoint's request
model so a direct caller cannot submit a template far larger than the frontend
allows (MaxBodyMiddleware only bounds the whole request body, not this field);
oversized templates now return a clean 422.

Apply sidecar-over-GGUF template precedence globally across cached snapshots
instead of per snapshot. A repo with multiple cached revisions previously
returned the first snapshot's template, so a newer GGUF-only revision could
win over an older revision's maintained chat_template.jinja sidecar, which
contradicted the documented intent that sidecars supersede the embedded copy.

* Guard per-model config against future-schema and lossy migration

Two forward-compatibility gaps in the versioned per-model config store:

- The load/apply path returned and normalized a stored record without checking
  its schema version, so a record written by a newer client was reinterpreted
  under the current schema and applied to a live model load, even though save,
  delete and eviction all refuse to touch future-schema records. Reject
  future-schema records on load too.
- The one-time legacy migration enforced the storage budget without protecting
  the entries it had just migrated and set the completion flag unconditionally.
  When storage was already full of future-schema records (which are unevictable
  by an older client), the migrated entries were the only evictable ones and
  could be dropped while migration was still marked complete. Protect the
  migrated keys during eviction and only mark migration complete when they
  survive, so it retries once space frees up.

* Discard chat-template validation results after the dialog closes

Server-side template validation is async, but closing or cancelling the editor
did not abort it, so a late-arriving valid response still called onSave and
applied a template the user had already dismissed. Track a validation token
that is bumped on close and ignore any validation result whose token is stale.

* Record native lease expiry when loading a picked GGUF from the chip

The pending-native-model chip loaded via stageOrLoad directly, bypassing
loadNativeModelIntent, so activeNativePathExpiresAtMs was never recorded for a
chip-loaded file. A later reload then either skipped the lease-expiry guard
entirely (expiry left null) or compared against a previously loaded file's
stale expiry, so reload could reuse an already-pruned token or wrongly block a
still-valid one. Route the chip through loadNativeModelIntent, which builds the
same selection and records the expiry.

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Prefer sidecar template for a directly selected local GGUF file

A direct .gguf file path read its embedded chat template without checking the
parent directory for a maintained sidecar (chat_template.jinja /
tokenizer_config.json), while directory and variant selections already prefer
the sidecar. That let the config editor preview or save a stale embedded
template for the same model depending on how it was selected. Check the parent
directory sidecars first, then fall back to the embedded copy, and cover both
paths with tests.

* Resolve cached chat template per revision, newest first

The earlier change searched every cached snapshot for a sidecar before
considering any snapshot's embedded GGUF template, which let an obsolete sidecar
from an older revision override the newest revision's template. Restore
per-snapshot resolution (newest first): a revision's sidecar still supersedes
its own embedded GGUF copy, but a newer revision is no longer overridden by an
older revision's sidecar.

* Preserve autoload transport conflicts and surface background busy downloads

- When a Hub autoload hits a transport conflict, keep pendingHubAutoLoad bound
  instead of clearing it. Clearing it re-keyed the download surface and its
  cleanup cancelled the conflict the toast tells the user to resolve, so the
  Hub resume affordance was gone the moment it appeared. Return early on
  conflict, mirroring the started branch, so resolving it from the Hub still
  auto-loads on completion.
- The background-download branch handled started and conflict but silently
  dropped a busy outcome, leaving the user with no feedback when a peer variant
  of the same repo was already downloading. Surface the same busy toast the
  autoload path uses.

Unsloth: appearance palettes, customization options, and control restyle (#7077)
* Unsloth: appearance palettes, customization options, and control restyle

Adds Standard, Classic, and Minimal color palettes to Appearance settings,
each adapting to light and dark mode. Classic is a neutral enterprise look
that reserves its blue accent for toggles, badges, and focus rings; Minimal
is strictly black, grey, and white.

Adds customization options scoped to the active mode: accent, background,
and foreground colors with an in-app color picker, UI and code fonts with a
searchable dropdown covering bundled, device, and imported fonts, font file
import, UI and code font sizes, contrast, pointer cursors, reduce motion,
font smoothing, and translucent sidebar. Settings persist through the
personalization API with backend validation and sync across devices.

Restyles core controls for a cleaner, flatter look in both modes: bordered
white input fields, fully rounded pills for single-row controls, no drop
shadows, simple straight-line chevrons replacing all rounded arrow icons,
and consistent hover tones in dropdown menus. Popovers now portal into the
open dialog so their lists scroll correctly inside modal dialogs.

Moves Language into General settings and Chat defaults into the Chat tab
above the Canvas section.

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Unsloth: appearance follow-ups, font options, and settings search

Neutralizes focus and selection rings across all palettes so highlighted
elements, including typing boxes and the selected palette card, never take
the accent color. The custom accent no longer recolors rings.

Restyles the color controls as filled pills showing the hex value inside,
with text and border contrast picked from the color's luminance. Menus in
popovers now match the app's dropdown menus: rounded-lg corners, tighter
padding, accent hover rows, and a bordered search field. Popovers inside
modal dialogs are modal so their lists scroll with the wheel. Outline
buttons share the same dark fills as dropdown triggers.

Adds heading and chat font options next to the UI and code fonts, each
using the searchable font dropdown and persisting through the
personalization API. Removes the translucent sidebar option end to end.

Adds settings search: a search field at the top of the settings sidebar
that filters setting names across every tab, grouped by tab with icons,
and jumps to the tab on click.

* Unsloth: use the shared accent token for dark hover fills

The settings dialog nav, its close button, the model selector, and the
project switcher hovered with hardcoded blue tinted greys (#3a3d43,
#2d2e32) in dark mode while every menu and sidebar uses --accent. All
hover and active pill fills now use the accent token so dark hovers are
the same everywhere and adapt to the active palette.

* Unsloth: settings search polish and jump to matched setting

Widens the settings dialog to 880px and the sidebar column to 248px so
the search field has more room. The search pill aligns with the left
start of the Settings title, gets more spacing above and below, and its
icon and placeholder sit slightly further left.

Search results now jump to the exact setting: rows and sections expose
their label as a data attribute, and picking a result opens the tab,
scrolls the matched row into view, and flashes it briefly.

* Unsloth: settings search bar spans the full nav pill width

The search field now starts and ends at the same edges as the nav hover
pills instead of being inset to the title text.

* Unsloth: address review findings on motion, sync, and font limits

Reduce motion Off now opts back out of the OS reduced-motion preference
for CSS animations via a force-motion class that the media rules skip,
and forcing reduce motion On keeps the loader exceptions (spinners,
loading dots, progress bars) animating.

When the color scheme follows the system, the resolved mode is now part
of the theme store snapshot, so an OS scheme flip re-renders consumers
and reapplies per-mode custom colors instead of leaving stale inline
variables from the previous mode.

Imported fonts get an aggregate size cap (4.4M characters) on both the
frontend sanitizer and the backend model so the persisted store always
fits browser localStorage quotas, with a clear error toast when an
import would exceed it. Backend validation also tightens imported font
names (rejects CSS delimiter characters) and requires strict base64
font data URLs, matching the frontend patterns.

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Unsloth: profile toggle to hide the sloth in the chat greeting

Adds a Show greeting sloth switch to Settings > Profile. The chat welcome
hides the mascot when it is off. The preference persists locally and
through the personalization API, with backend validation and tests, and
the row is reachable from settings search in all four locales.

* Unsloth: control restyle, dropdown scrolling, and palette consistency

Settings sidebar puts search on top with the tab list under a small
Settings label. Combobox popups scroll with the wheel inside dialogs by
falling back to manual list scrolling while a dialog scroll lock is
active, and the local model selector popover became modal for the same
reason. Number inputs swap native spinners for a shared grey stepper
that clamps to min, max, and step. Run settings fields in light mode use
the same white fill and border as the settings dialog. Selection and
focus rings derive from each palette's border color instead of near
black, hover borders soften the same way, the Classic sidebar stays
white like Standard, decorative greens follow the palette accent, and
meaning-carrying marks like the hub verified badge keep the brand green
in every palette.

* Unsloth: palette card selection keyed off the palette attribute

Switching palettes restyles the whole page the moment data-palette lands
on the html element, but the React re-render that moves the selection
classes arrives later, so the ring and check briefly stayed on the
previous card with the new palette's colors. The active ring and check
now key off html[data-palette] in CSS, so they swap in the same style
pass that swaps the tokens. Also adds breathing room around the settings
search bar and under the Settings label, shortens the greeting sloth
description, and renames the avatar section to Or pick a sloth profile
picture in all locales.

* Unsloth: restore neutral rings, drop the palette check, sidebar spacing

Puts the ring tokens back to their fixed per palette values and removes
the hover border darkening, undoing the derived border experiment. The
selected palette card no longer shows a check since the ring already
marks it. The settings sidebar search bar, nav pills, and search results
get a little side padding, and the Settings label lines up with the pill
text.

* Unsloth: indicator restyle, sidebar menu customization, edge fade toggle

- Derive focus and selection rings from the border color so indicators
  stay 1px and adapt to every theme and palette
- Suppress mouse focus rings except on pressed controls to remove the
  selection flash on the avatar and palette pickers
- Defer settings panel rendering so the active nav pill updates instantly
- Customizable sidebar user menu with drag to reorder and shortcuts to
  the settings tabs
- Grey hover for the standard light palette instead of green
- Borderless controls in dark mode with fill based focus states
- Profile picture: no picture option, pencil edit icon, atomic selection
- Font dropdowns: narrower triggers and the resolved default shown as
  Inter Variable (Default)
- System prompt border darkens on focus
- New appearance setting to swap edge fades for thin divider lines
- Move the theme bootstrap to an external script to satisfy CSP

* Unsloth: harden theme boot and Firefox scroll container focus

- Guard the theme and palette storage reads separately so a blocked
  localStorage (private browsing) still resolves a mode from the OS
  preference instead of skipping the boot entirely
- Firefox makes scrollable containers keyboard focusable and drew its
  3px UA outline on them; swap it for the app's soft 1px indicator

* Unsloth: make the UI and code font settings reach the font utilities

The theme block declared the sans and mono stacks as literals, so
Tailwind inlined them into every font-sans and font-mono utility at
build time and the runtime overrides from Settings > Appearance never
applied. Reference the :root tokens instead, matching how the color
tokens already work.

* Unsloth: in-dropdown font upload, accent meters and avatar, naming cleanup

- Move font importing into each font dropdown: Upload and Select folder
  sit side by side under the list, imported fonts get an inline remove,
  and the standalone Import font row is gone
- Uploads reuse fonts the user already has (bundled, imported, or
  installed, matched by file name with style suffixes stripped) instead
  of embedding a duplicate copy; only new fonts are embedded
- Folder scan lists font files from a picked folder in every dropdown
  for the session; picking one imports it through the same path
- Fallback avatar uses the control accent with a readable foreground
  instead of the neutral primary that rendered black outside standard
- Monitor bars, progress defaults, sliders, and usage meters use the
  control accent; warning and danger tiers stay amber and red
- User facing strings that called the app just Studio now say Unsloth
  in all four locales, keeping Unsloth Studio and LM Studio intact

* Unsloth: left align the font upload actions and divide them

Upload and Select folder now read from the left like the list items,
with a short vertical rule between the two.

* Unsloth: keep sliders neutral and the chat greeting on Hellix

- Sliders are controls, not meters, so their fill goes back to the
  neutral primary instead of the palette accent
- The base h1 rule reads --font-heading with !important and the chat
  thread root resets that variable to the sans stack, which pulled the
  greeting off Hellix; restore the stack on the greeting element

* Unsloth: move the None avatar cell last and keep footer actions on one line

- None sits after the sloth pictures instead of leading the grid
- Upload shrinks to its label so Select folder no longer wraps

* Unsloth: size the folder action to its label

Both footer actions now hug their content so the hover pill does not
stretch across the leftover row width.

* Unsloth: separators only between unrelated settings clusters

Rows inside a titled section are related, so the per row divide-y is
gone from SettingsSection. A SettingsGroupDivider marks the two real
boundaries in the theme section (colors to fonts, fonts to contrast)
and the Clear all chats row gets its destructive border back now that
divide-y no longer draws one for it.

* Unsloth: balance the two font upload actions

Both actions share the footer row evenly again; nowrap keeps Select
folder on one line at the narrower width.

* Unsloth: drop the theme section dividers and split the chat menu groups

The colors, fonts, and contrast rows read fine without rules, and the
chat menu gains its one real boundary between the pin toggles and the
disclaimer rows.

* Unsloth: normalize oversized sidebar menus and reject newline font data URLs

Two backend validation fixes in PersonalizationCustomization:

- sidebarMenu refused any list longer than the number of distinct ids
  because Field(max_length) is enforced before the dedupe validator runs.
  A stale or duplicated payload that would normalize to one entry per id
  was rejected outright, defeating the normalizer that exists for exactly
  that case. Cap the incoming list at a generous multiple so it reaches
  the validator; a pathologically long list is still refused.

- The imported font dataUrl validator used re.match on a pattern ending
  in $, which also matches just before a trailing newline, so
  "data:font/woff2;base64,AAAA\n" passed even though the frontend JS
  pattern rejects it. Use re.fullmatch for parity.

Adds covering tests for both.

* Unsloth: preview fonts in their own typeface and slim the color pills

- Every font dropdown entry, the default item, and the closed trigger
  render in the font they name, falling back to the UI stack for
  families the browser cannot resolve
- Color swatch pills drop from 36px to 28px so they sit closer to the
  row label height

* Unsloth: drop the font row and theme section descriptions

The labels carry the meaning on their own; the mode switching note in
particular read long and confusing.

* Unsloth: let the chat greeting follow the heading font setting

The greeting stays on Hellix by default but adopts a chosen heading
font through a --custom-heading-font variable the applier sets only
while an override exists, so the thread root's sans reset for chat
prose no longer hides the user's pick from the greeting.

* Unsloth: divide the theme section clusters and align the color pill height

Separators return between colors and fonts and between fonts and
contrast, and the color pills share the 32px height of the font
dropdown triggers.

* Unsloth: color pills at half the dropdown width

Fixed w-24 against the w-48 font triggers, with tighter padding so the
hex value still fits.

* Studio: update dep-removal test after next-themes was replaced

The frontend no longer declares next-themes or imports it in src (it was
replaced by the custom theme store and boot script), so the checker now
reports its removal as a safe no-op. The C1 and C8 fixtures in
test_frontend_dep_removal.py still asserted next-themes was a used
dependency, which fails the studio frontend CI dependency-removal safety
check. Update C1 to expect a no-op PASS and drop next-themes from the C8
expected failures so the suite matches the checker's correct output.

* Studio: remove unused ageLabel and exportCollectionJsonl helpers

* Studio: fix blocked-storage theme desync, search jump race, font validation

- theme-store.ts: keep an in-memory currentTheme/currentPalette so a selected
  value survives when localStorage is blocked (private browsing). The snapshots
  previously re-read empty storage and reverted React state to the default while
  the DOM already changed. The matchMedia handler no longer re-reads storage, so
  it cannot clobber the in-memory choice; cross-tab storage events still adopt.
- settings-dialog.tsx: the search jump waited a single fixed 60ms for the
  deferred tab panel to render, then silently missed under render lag. Retry
  across animation frames until the target row exists, then scroll and flash.
- settings.py: apply the font-name character check to the four selected-font
  fields (uiFont/headingFont/chatFont/codeFont), and forbid backslash, comma,
  slash and control characters so a name cannot escape the quoted CSS
  font-family or smuggle extra fallbacks. Adds covering tests.

* Fix appearance customization edge cases for PR #7077

- Reset all local preferences now also clears palette and appearance customization
- Number input wrapper keeps full width so fields fill their flex/grid cell, and the stepper stays pinned to the field edge
- Number stepper snaps to the min anchored step grid like the native spinner instead of leaving a step-invalid value
- Code font now applies to chat code fences and inline code via a dedicated token
- Reduce motion (on/off) is honored by onboarding/tour confetti and the theme toggle view transition
- Re-importing a font under the same name with new bytes now swaps the FontFace
- Keep local customization when a synced record predates the customization field, and re-push it

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Align client font name sanitization with server validation for PR #7077

sanitizeFont now strips the same characters the backend _FONT_NAME_FORBIDDEN
rejects (backslash, slash, comma, backtick) plus control chars, so a locally
chosen font name can no longer pass the client but fail the personalization PUT
and silently stall appearance sync.

* Address follow-up review items for PR #7077

- Number input wrapper carries React Flow interaction classes (nodrag/nopan/nowheel) so clicking the stepper arrows increments instead of dragging the node
- Preserve local palette and greeting-sloth toggle when the synced record predates those fields, and re-push them, mirroring the customization handling (new paletteSaved and greetingSlothSaved response flags)
- Add settings-search scroll targets (data-settings-label) for the Profile title, description, display name, nickname, and avatar shape rows

* Preserve absent personalization fields on PUT for PR #7077

A stale client that omits palette or customization previously had those
defaults materialized by model_dump() and persisted, which flipped
paletteSaved/customizationSaved to true and defeated the legacy detection.
The PUT now dumps only the request's set fields and merges them onto the
stored record, so omitted fields keep whatever was already stored.

* Persist theme and palette via a fixed allow-list for PR #7077

The theme/palette values reach setTheme/setPalette from the authenticated
personalization sync, which made the CodeQL clear-text-storage query treat
writing them to localStorage as storing sensitive data. Store a re-derived
literal from a constant map instead, so a plain UI preference is not tracked
as sensitive; behavior is unchanged.

* Harden imported-font handling for PR #7077

- syncImportedFonts: a rejected FontFace.load() only clears the registry entry
  if it still points at that face, so a same-name re-import while the old load
  was pending is no longer untracked/leaked.
- Cap imported-font names to the backend length (100) so an over-long name can
  no longer pass the client but fail the personalization PUT and stall sync.
- Add a backend test that a stale PUT preserves an existing stored palette and
  customization (not just that absent fields stay absent).

* Return the merged personalization record from PUT

The PUT /personalization handler returned the request payload, which
Pydantic had already filled with defaults for any field the client
omitted. A partial or stale write (for example a client sending only
theme) therefore got back a response that contradicted both storage and
the next GET: preserved fields like palette and the custom font showed
their defaults instead of the stored values.

Return model_validate(merged) so the response mirrors what was stored.
The stored record is still the full merged dict, so legacy fields the
model does not know about are preserved as before.

* Fix small UI and keyboard-focus defects in appearance settings

- Settings search now scrolls to the result within its destination tab
  instead of a same-named row in the previously rendered deferred tab
  (for example "Storage" and "Models folder" appear in both General and
  Resources).
- The reduce-motion segmented control honors its own Off/On/System choice
  by reading useReducedMotionConfig instead of the OS-only useReducedMotion.
- The color picker saturation/value area is operable by keyboard, so the
  role="slider" surface responds to the arrow keys it advertises.
- Profile avatars and palette cards show a visible keyboard focus ring
  again.
- Guard the persisted appearance-customization write so a blocked or full
  localStorage does not throw out of a store action, matching the theme
  store.
- Import the appearance store symbols from the settings feature barrel.

* Tighten appearance fix comments

Studio: resolve llama.cpp prebuilts via the release-assets CDN to avoid GitHub API rate limits (#7086)
* Studio: resolve llama.cpp prebuilts via the release-assets CDN to avoid GitHub API rate limits

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Studio: resolve manifest-named prebuilt assets on the download-host fast path

Add tag-pinned CDN URLs for any manifest artifact whose hash is keyed under an
upstream-tag alias in the checksum asset, so the fast path resolves the same
assets the API path does. Cover the resolve body directly (only download_bytes
stubbed) and soften the doc's validation-equivalence wording.

* Studio: pin llama.cpp fast path to the releases/latest redirect tag

Derive the authoritative latest tag from GitHub's /releases/latest redirect
target instead of trusting the checksum asset's self-reported release_tag, so the
existing release_tag cross-check in parse_approved_release_checksums is a real
check again: a stale or mis-tagged checksum asset now falls back to the API. Pin
every fast-path URL to that tag. Fall back to the API on a manifest 404 as well,
since an in-progress release can publish the checksum asset before the manifest,
matching the sha256 404 handling. Document the releases/latest (created_at /
make_latest) versus published_at ordering divergence and why it is an accepted,
mitigated tradeoff.

* Studio: drop the llama.cpp prebuilt-resolution doc

Remove studio/docs/llama-cpp-prebuilt-resolution.md and the docstring pointer to
it; the resolution rationale (the created_at/make_latest vs published_at ordering
nuance) stays inline in _download_host_latest_release_tag.

* Studio: tighten llama.cpp download-host fast-path comments

Studio: remove dead direct_linux_release_plan path (#7030)
parse_direct_linux_release_bundle and direct_linux_release_plan are no
longer reached by any live code path. Fork Linux installs resolve through
_fork_manifest_release_plans -> _linux_published_attempts, and the upstream
(ggml-org) path uses direct_upstream_release_plan. The dead parser also
called _resolve_linux_bundle_profile, which no longer exists, so its CUDA
branch would raise NameError if ever executed.

Drop both functions and the obsolete TestDirectLinuxNvidiaCpuGate; its live
equivalent TestLinuxPublishedAttemptsNvidiaCpuGate already covers the
NVIDIA no-silent-CPU behaviour.

Retry the Studio UI shutdown re-login on transient goto timeout (#7027)
* Retry the Studio UI shutdown re-login on transient goto timeout

The Chat UI Playwright smoke intermittently failed at the pre-shutdown
re-login: page.goto('/login') can hit a 60s TimeoutError on a slow runner
even while the server is healthy, and the surrounding except only tolerated
ERR_ABORTED / interrupted-navigation, so a plain timeout hard-failed the job.

Wrap the re-login goto/wait/fill/submit in the same 3-attempt retry the
change-password step already uses (recover_or_replace_page between tries,
per-attempt fail screenshots, wait_for_health pre-gate). The composer wait
stays outside the loop so a retry never re-navigates after login has set
tokens (which would redirect to /chat via the guest guard); it remains the
authoritative confirmation, so a genuinely broken login still fails.

* Catch transient login-request failures and preserve error listeners on recovery

Wait on the /api/auth/login POST inside the retry (via click_and_wait_for_response)
so a transient 4xx/5xx is retried in-loop instead of surfacing only at the
out-of-loop composer wait, matching the change-password step. When
recover_or_replace_page swaps in a fresh page, re-attach the pageerror/console
listeners so error tracking survives the replacement.

Stabilize floating monitor drag (#6984)
* Stabilize floating monitor drag

* Restore floating monitor exit animation

* Harden Windows Studio smoke checks

* Keep API menu badge removed

* Apply no-build-tools env overrides in-script

The runner does not apply step-level env keys containing parentheses,
so ProgramFiles(x86) kept its real value and Find-VsBuildTools still
detected VS through vswhere. Set the overrides inside each pwsh step
instead; child processes inherit them. The resolver step moves to pwsh
because bash cannot export a variable named ProgramFiles(x86).

* Reset chat UI session without a second browser context

macOS runs Chromium with --single-process, where closing the last
context tears down the whole browser, so the shutdown re-login died
with TargetClosedError on new_page. Clear cookies and swap pages
inside the same context instead, opening the replacement page before
closing the old one.

* Keep the no-build-tools Path filtered across session refreshes

install.ps1's Refresh-SessionPath and setup.ps1's Refresh-Environment
rebuild the session Path from the Machine and User registry scopes, so
the process-level filter could be undone mid-install and re-expose
CMake. Filter those scopes in the Prepare step with normalized dir
matching and restore them in cleanup.

* Drop stale localStorage auth tokens before re-login

Auth tokens live in localStorage, not cookies, and the login guest
guard redirects on their mere presence. Remove them during the session
reset so the /login navigation is deterministic instead of relying on
the tolerated redirect bounce.

feat: detect installed coding agent CLIs in Studio settings (#6909)
* feat: detect installed coding agent CLIs in Studio settings

The API-keys panel only ever showed the "claude" flavor of the
`unsloth start` command, so anyone using Codex, OpenCode, OpenClaw,
Hermes, or Pi had to manually rewrite the copied command by hand.

Add a backend check that looks for each agent's CLI binary on PATH
(shutil.which, mirroring the pattern already used elsewhere in
studio/backend/utils) and expose it as GET /api/settings/coding-agents.
The API-keys panel now renders a picker for all six supported agents,
marks the ones it finds installed, and defaults to one of those instead
of always falling back to claude.

Includes unit tests for the detection helper.

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* address review feedback on coding-agent detection

Three fixes from PR review:

- detect_installed_coding_agents now treats a PATH lookup failure as
  "not installed" instead of letting it bubble up and break the
  settings endpoint; added a regression test for it.
- CodingAgentsResponse.agents is now typed as an immutable tuple
  instead of a list built from one, matching CODING_AGENTS itself.
- Fixed a race in the API-keys panel: picking an agent while the
  installed-CLI check is still in flight could get silently overwritten
  once that check resolved. A ref now tracks whether the user has made
  a manual choice, so the auto-detected default only applies before
  that happens.

* Address Codex feedback: GGUF gating and remote-detection scope

- codex refuses to launch against a non-GGUF (transformers-backed) model
  (unsloth_cli's _require_gguf_for_codex), so auto-defaulting to it produced
  a copy-pasteable command that fails immediately whenever the loaded model
  isn't GGUF. Add useActiveModelIsGguf() (looks up the active checkpoint in
  the chat runtime store) and a correction effect that steers the auto-pick
  away from codex unless the loaded model qualifies, without ever touching a
  choice the user made by hand.
- Detection runs via shutil.which on the Studio backend host, which isn't
  the same machine as the browser in a tunnel/remote session. Reword the
  'installed'/'detected' copy to say so explicitly when the tunnel URL is
  in use, instead of implying the check ran on the viewer's own device.

* Rework auto-default per review: loopback gating + inline GGUF check

Replaces the previous approach with the exact shape discussed on the PR:

- Export isLoopbackHost/normalizeHost from agent-command.ts. The detection
  endpoint runs shutil.which on the Studio backend, which only describes the
  browser's own machine when the base this panel targets resolves to
  loopback. For a LAN or tunnel/remote base, gate the whole thing off --
  don't mark anything as "detected" and don't let it drive the default --
  instead of just relabeling the copy.
- Drop the separate GGUF-correction effect and useActiveModelIsGguf hook.
  Read useChatRuntimeStore.getState().activeGgufVariant inline inside the
  existing detection effect's .then() (so it doesn't need to sit in the
  effect's deps), and pick the first detected agent that isn't codex unless
  the loaded model is GGUF, leaving the existing default untouched when no
  compatible agent is detected.

Verified both branches (loopback vs LAN/tunnel base, gguf vs non-gguf,
manual pick preserved, no-compatible-agent fallback) with a standalone
port of the .then() logic.

* Address latest Codex findings: stale detection, model swap, cache

- Clear detectedAgents (and skip the network call entirely) when the panel
  leaves a loopback base, instead of leaving a previous loopback detection
  result marked 'installed' for a command that now targets a LAN/tunnel/
  remote host.
- Add a separate, network-free correction effect keyed on the live
  activeGgufVariant: if codex was auto-picked while a GGUF model was loaded
  and the user then switches to a transformers-backed model while this panel
  stays mounted, steer away from codex instead of leaving a command that
  unsloth_cli's _require_gguf_for_codex will now reject. Never touches a
  manual pick.
- Drop coding-agents.ts's module-lifetime cache. Installed-CLI detection is
  environment state, not a persisted setting, so a stale positive/negative
  from before the user installed something (or reopened the tab) is worse
  than one extra cheap local API call per mount; keep only the in-flight
  de-dupe for concurrent callers.

Verified the correction-effect logic (gguf->non-gguf swap with/without a
fallback, still-gguf no-op, manual pick never overridden) with a standalone
port of the effect.

* Make the codex/GGUF auto-pick symmetric in both directions

The correction effect only steered away from codex when the model stopped
being GGUF; it never steered back toward codex if the model became GGUF
*after* a non-GGUF-gated fallback had already picked something else (e.g.
codex is the only detected CLI, a transformers model is loaded so the
selection correctly falls back to the claude default, then the user loads a
GGUF model while the panel stays mounted -- codex never gets reconsidered).

Consolidate into one effect that re-derives the preferred detected agent
from scratch whenever detectedAgents or activeGgufVariant changes, in either
direction, instead of only reacting to the codex-specific downgrade case.
The fetch effect now only populates detectedAgents/availableAgents; this
effect is the single source of truth for what gets auto-picked from that
list. Never overrides a manual choice.

Verified both transition directions plus the manual-pick-survives and
initial-detection cases with a standalone port of the derivation logic.

* Reset the auto-pick to the default when it stops being trustworthy

Two more real gaps from the latest Codex pass on d988f52:

- The unified derivation effect only handled the case where a *different*
  detected agent could take over. If codex was the only detected agent and
  auto-picked while a GGUF model was loaded, then the model stopped being
  GGUF, 'preferred' came back undefined and the effect silently left the
  selection on codex -- exactly the command unsloth_cli's
  _require_gguf_for_codex now rejects. Fall back to DEFAULT_AGENT in that
  case instead of leaving it untouched.
- Leaving a loopback base cleared detectedAgents (so the 'installed' badges
  correctly disappear) but left whatever agent had been auto-picked from
  that now-stale, server-side-only detection still selected. Reset to
  DEFAULT_AGENT there too, unless the user picked by hand.

Introduces a shared DEFAULT_AGENT constant instead of repeating the "claude"
literal at each reset site. Verified all five cases (both new resets, both
manual-pick-survives variants, and the existing multi-detected-agent
fallback still preferring another compatible agent over resetting) with a
standalone port of the effects.

* Derive GGUF-ness from the actual loaded state, not just the variant string

activeGgufVariant only covers an HF-repo GGUF pick (a specific quant
variant string). A direct local .gguf file -- custom folder, LM
Studio, or drag-drop -- is just as much a GGUF the codex preflight
(unsloth_cli's _require_gguf_for_codex) would accept, but it never has
a "variant" to report, so it read as non-GGUF here even though
/api/inference/status correctly reports is_gguf: true for it. That
mismatch could leave a Codex-only install not auto-selected, or reset
an auto-picked Codex, for a model that actually supports it.

Combined activeGgufVariant with activeNativePathToken (covers the
drag-drop/picked-file case) and ggufContextLength (only ever populated
when the backend last reported is_gguf: true for the active model, see
applyActiveModelStatusToStore) so all three paths a model can be GGUF
through are covered, matching the same is_gguf-or-equivalent check
hasGgufSource already applies to a staged pick elsewhere in this
codebase.

* Clear stale native-path token on a non-GGUF status refresh

When a native (drag-dropped or picked) GGUF was loaded and the backend later
switches to a transformers model outside the UI load path, refresh() adopts the
new /api/inference/status via setCheckpoint and applyActiveModelStatusToStore.
Those reset activeGgufVariant and ggufContextLength but never clear
activeNativePathToken, so the isGguf OR stays true after the switch and a
Codex-only detection auto-selects unsloth start codex for a non-GGUF model its
preflight rejects.

Drop activeNativePathToken in applyActiveModelStatusToStore whenever the status
is non-GGUF. A real GGUF load reports is_gguf: true, so its token is preserved
(the load path owns it); only a non-GGUF status clears it.

Add RDNA 2/3/4 ROCm routing tests via a CPU-only torch spoof (#6935)
* Add RDNA 2/3/4 ROCm routing tests via a CPU-only torch spoof

Introduces tests/_zoo_rocm_spoof.py, the ROCm sibling of _zoo_aggressive_cuda_spoof.py: it reuses the CUDA spoof's torch.cuda no-op machinery and overlays an AMD Radeon identity (torch.version.hip, gcnArchName, capability) for any RDNA 2/3/4 gfx target, so hip code paths run on CPU-only CI with no AMD hardware.

tests/studio/install/test_rocm_rdna_routing.py then asserts unsloth_zoo routes every RDNA arch (gfx1030/1031/1032/1034, gfx1100/1101/1102, gfx1150/1151, gfx1200/1201) correctly: device_type resolves to hip, llama.cpp target resolves to (rocm, gfx), and the per-family ROCm bundle suffix (gfx103X/gfx110X/gfx120X, or self for gfx1150/1151) is picked. The torch-facing checks run in a subprocess so the spoof never leaks into sibling tests and DEVICE_TYPE (cached at import) resolves from a clean process; the pure gfx-family mapping runs in-process. Guarded by importorskip so it runs where torch and unsloth_zoo are installed (the Repo tests CPU job) and skips elsewhere.

ROCm-on-WSL: support discrete Radeon (RDNA 3/4) in WSL, not just Strix Halo (#6915)
* WSL ROCm: generalize ROCm-on-WSL bootstrap from Strix-only to any RDNA arch

install_rocm_wsl_strixhalo.sh hardcoded gfx1151, so its verify step died on
discrete Radeon cards even though the ROCm + librocdxg setup is arch-agnostic.
Auto-detect the GPU arch from rocminfo (override via UNSLOTH_WSL_GFX), verify any
GPU agent enumerates over DXG, and map the arch to AMD's per-arch wheel family for
the optional smoke test (injecting librocdxg into torch/lib so torch's bundled
ROCr finds the DXG bridge). Verified on gfx1200 (Radeon RX 9060 XT) in WSL2 +
Ubuntu 24.04 -- torch.cuda now enumerates the GPU.

* WSL ROCm: trigger the ROCm-on-WSL bootstrap for discrete Radeon GPUs too

_maybe_bootstrap_rocm_wsl only fired for Strix APUs (matched via /proc/cpuinfo,
which discrete cards don't appear in). Add _wsl_amd_gpu_name() -- queries the
Windows host via WMI -- and broaden the trigger gate plus the 'already-usable
ROCm' rocminfo check from gfx1151-only to any real GPU agent (gfxNNNN, excluding
the gfx11-generic fallback ISA). The generalized bootstrap then auto-detects the
arch. Enables 'curl install.sh | sh' to set up ROCm-on-WSL on discrete Radeon RX
7000/9000 in WSL2 + Ubuntu 24.04, not just Strix Halo/Point.

* WSL ROCm: address review -- filter generic ISA in bootstrap, bound the host GPU query

- install_rocm_wsl_strixhalo.sh: exclude the gfx11-generic fallback ISA in arch
  detection (grep -v generic), matching install.sh's rocminfo check, so a generic
  agent listed before the real one can't be picked as the arch.
- install.sh: wrap the powershell.exe Win32_VideoController query in _run_bounded
  (10s timeout) so an unstable WSL-interop / busy host can't hang the installer.

* WSL ROCm: harden arch-detect + librocdxg copy under set -eo pipefail (review)

- _detected_gfx: append '|| true' so a no-GPU rocminfo (empty pipeline, non-zero
  under pipefail) doesn't abort the assignment before the '[ -z ]' branch prints
  the diagnostic + die message.
- smoke-test librocdxg copy: gate on '[ -d "$_tlib" ]' instead of '[ -n ]' so a
  non-directory value can't make cp rename librocdxg to 'lib'.

* WSL ROCm: address Codex review (gfx000, 24.04 reroute for discrete, test locator)

- Exclude gfx000 (the CPU agent) from the WSL 'usable ROCm' check and the bootstrap
  arch-detect: match gfx[1-9] (nonzero arch), so a partial ROCm install that only
  reports the CPU ISA no longer short-circuits the librocdxg setup. (P2)
- Reuse the Ubuntu-24.04 reroute for discrete Radeon: broaden
  _maybe_reroute_strixhalo_to_2404's gate with the same _wsl_amd_gpu_name (WMI)
  fallback, so a discrete card on 26.04 reroutes to a 24.04 distro like Strix does
  instead of falling to CPU. Moved _wsl_amd_gpu_name above the reroute and made it
  self-contained + 10s-bounded (it runs before _run_bounded is defined). (P2)
- Update TestInstallShDropinPersistence to locate the gate by its unique
  '!/generic/' clause now that the gfx1151 literal is gone. (P1)

* Condense ROCm-on-WSL comments in install.sh and bootstrap helper

* Guard WSL reroute from NVIDIA hybrid hosts and fix GFX-override pipefail check

* Honor CUDA_VISIBLE_DEVICES-hidden NVIDIA in the WSL reroute guard

* Reuse _has_usable_nvidia_gpu in the WSL reroute guard

Guard Windows ROCm torchao override skip (#6837)
* Fix: skip fp16/bf16 validation for full finetuning in RL trainers

When doing full finetuning (FFT) of a bfloat16 model, the fp16/bf16
mismatch validation fires before the corrective logic runs, causing a
misleading error even though the code would properly handle it downstream.
Skip the validation when full_finetuning is active.

Fixes #6731

* Fix: auto-correct fp16/bf16 mismatches for full finetuning before validation

Instead of entirely skipping validation (which could let mismatches
through when mixed_precision_dtype is float32), auto-correct explicit
fp16/bf16 settings that conflict with the model's dtype for FFT. This
way the existing validation still catches real mismatches for non-FFT
cases, and the corrective logic below handles the normalized settings.

Fixes the issue raised in Codex review of PR #6813.

* Guard Windows ROCm torchao override skip

Detect installed ROCm torch directly before applying the torchao override so Windows ROCm environments never install the crashing torchao package even if the earlier ROCm-installed flag is missing.

Studio: multi-select export formats, portable FP8/INT8, GGUF LoRA, and source parity (#6767)
* Studio: expose full compressed-tensors scheme set in an export formats dropdown

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Studio: multi-select export formats, portable torchao FP8/INT8, GGUF LoRA, source parity

Export page overhaul on top of the formats dropdown:

- Unify merged precision into one sorted multi-select list (16-bit first, then
  8-bit, then 4-bit). Drop "vLLM" from labels, add INT8 (W8A8), INT8 (W8A16),
  INT4 (W4A16), MXFP4, MXFP8. Quick formats render as toggle pills; the rest live
  in a multi-select "More formats" dropdown, so several formats export in one run.
- Add a portable torchao FP8/INT8 save path (Float8WeightOnlyConfig /
  Int8WeightOnlyConfig) that needs no NVIDIA GPU to produce and loads in vLLM.
  FP8 serializes to safetensors, INT8 to .bin. Wired into save_pretrained_merged
  and push_to_hub_merged via a TORCHAO_EXPORT_SCHEMES registry and
  _unsloth_save_torchao, parallel to the compressed-tensors path.
- Hide NVIDIA-only compressed-tensors formats when no NVIDIA GPU is present; keep
  16-bit and portable FP8/INT8. The backend also rejects a compressed request on
  non-NVIDIA hardware so it stays authoritative.
- Relax merged export to non-PEFT models so Local Model and Hugging Face sources
  get the same 16-bit / compressed / portable options.
- GGUF: send the whole quant list in one call (merge once, quantize many).
- LoRA: add a GGUF adapter option (convert_lora_to_gguf.py) with an outtype
  select (f16/bf16/f32/q8_0/auto), alongside the safetensors adapter.
- Thread the new fields through models, routes, orchestrator, and worker; extend
  the export tests.

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Studio: gate export by accelerator with a torch-aware reason; fix export save dir naming

Export runs through Unsloth, which requires a compute accelerator (NVIDIA/AMD/Intel
GPU or Apple MLX) and has no CPU code path, so a bare-CPU host cannot export even
with PyTorch installed. Add export_capability() in utils/hardware that reports
export_supported plus a precise reason so the UI stops showing a generic "no GPU":

  - pytorch_not_installed: a --no-torch install (even a physical GPU is unusable)
  - no_accelerator: PyTorch present but no supported accelerator (bare CPU)
  - mlx_unavailable: Apple Silicon where the MLX stack is missing or too old

Expose the fields on /api/system/hardware and /api/system, and guard the mutating
export routes (load-checkpoint, export/merged|base|gguf|lora) with HTTP 400 and the
reason, leaving read-only endpoints usable so the Export page still renders.

Make core/export/export.py import without PyTorch and without a usable accelerator
(the Unsloth import is caught) so the export worker degrades to a clear message
instead of crashing at import.

Frontend: keep /export reachable on chat-only hosts and gray out the method and
format options with the backend reason (Alert plus disabled MethodPicker) instead
of silently redirecting to /chat, so users see why export is unavailable.

Also fix the export save directory producing "model/null" for Local Model and
Hugging Face sources that have no run/checkpoint, naming the folder from the model id.

* CI: validate Studio export capability gating on Linux, Windows and macOS

Add a small pytest matrix that runs studio/backend/tests/test_export_capability.py
on ubuntu-latest, windows-latest and macos-latest. It confirms, on each real OS,
that hardware.export_capability() reports the right decision and reason
(pytorch_not_installed, no_accelerator, or mlx_unavailable) and that the export
backend imports without PyTorch and degrades to a clear message instead of crashing.

Hosted runners have no GPU/MLX, so this covers the "export unavailable, here is why"
path a Mac/Windows user without an accelerator sees; a real accelerator export is
validated separately. The job installs only a CPU PyTorch plus the backend import
deps (no unsloth, triton, or llama.cpp), so it runs in seconds with no GPU.

* Studio export: address Codex review (source-aware gating, GGUF LoRA token/MLX/guard)

Frontend (export-page):
- Gate LoRA and quantized-model restrictions on the active source. isAdapter /
  isQuantized come from the selected checkpoint; in Local Model / Hugging Face
  ("model") source mode they were stale, so LoRA stayed wrongly enabled for a
  direct base model (backend then rejects "No adapter to export") and a stale
  "quantized" flag disabled every method for an unrelated, exportable model. Add
  effectiveIsAdapter / effectiveIsQuantized (false outside checkpoint mode) and use
  them in the method-reset effect and the MethodPicker disabled state.
- Hide the GGUF LoRA option on a macOS/MLX host (the backend rejects GGUF LoRA on
  MLX), so users no longer pick it, wait through the load, and always fail. Disable
  the "GGUF adapter" button on a Mac host and never send loraGguf there.

Backend (core/export/export.py):
- Pass the HF token into the GGUF LoRA conversion (save_pretrained_gguf), so a
  gated/private base model's config fetch in convert_lora_to_gguf.py is
  authenticated; without it the load can succeed but the conversion fails.
- Guard the save_pretrained_gguf capability check with getattr so an older Unsloth
  model that lacks the method returns the clean "not supported" message instead of
  an AttributeError that surfaces as a generic 500.

* Studio export: address 2nd Codex review (CI index, empty merged, test import)

- studio-export-capability-ci.yml: add --extra-index-url https://pypi.org/simple to
  the torch install so torch's transitive deps still resolve; --index-url alone
  replaces PyPI with only the CPU wheel index, which does not serve all of them.
- export-page handleStart: reject an empty merged selection (mirrors canExport), so
  clicking the panel's Start button with every precision pill deselected no longer
  submits mergedSelections: [] and launches an unintended default 16-bit export.
- test_export_imatrix_compressed: the torchao-registry test now reads unsloth/save.py
  as text (like the other ast/string checks) instead of `import unsloth.save`, which
  raised ModuleNotFoundError in the CPU studio-backend suite that has no unsloth
  installed.

* Studio export: make comments succinct across the export changes

* Studio export: use load token for local GGUF LoRA export of gated bases

* Studio export: harden portable torchao path and gate multi-format Hub push

torchao (_unsloth_save_torchao):
- merge to an isolated temp staging dir so a co-selected 16-bit output at save_directory is not deleted
- narrow VLM detection to vision_config / ForVisionText2Text so T5/BART/Whisper are not misrouted
- forward trust_remote_code (from auto_map) to the reload so custom-code models export

Export UI:
- hide portable torchao formats on macOS/MLX (backend rejects quantized export there)
- restrict a Hub merged export to a single format (each writes to the repo root)

* Studio export: torchao tokenizer remote-code + XPU offload, scale GGUF timeout

torchao (_unsloth_save_torchao):
- honor auto_map in the staged tokenizer/processor configs (not just model.config) when
  deriving trust_remote_code, so custom-code tokenizers reload after the merge
- offload single-device XPU models to CPU (and empty the XPU cache) before the reload, matching
  the CUDA path, so an Intel GPU that fits the model once does not OOM on the second copy

Export orchestrator:
- scale the GGUF wait timeout by the number of requested quants so a multi-quant list export of a
  large model does not time out at a flat 3600s

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Studio export: show portable torchao formats only on non-NVIDIA (CPU) hosts

Portable torchao FP8/INT8 is the fallback for hosts without the NVIDIA compressed-tensors path.
On an NVIDIA GPU the compressed-tensors FP8/FP4/INT formats are the intended path (llm-compressor
auto-installs), so hide the portable duplicates there; keep them on CPU / non-NVIDIA hosts and
continue hiding them on macOS/MLX.

* Studio export: report all output folders and the exported formats

- Multi-format merged export now collects every sibling output directory (one per selected
  precision) instead of only the last; the success banner lists them all.
- Show the selected precision formats in the run summary (a Formats row, like GGUF Quantizations),
  so the panel says what is being exported rather than just 'Merged Model'.
- Persist the selected formats in the run summary and seed them on mount, so navigating away and
  back (or toggling the export method) restores the selection instead of resetting to 16-bit.

* Studio export: list all output formats, add GGUF LoRA target, default Q8_0, auto-select newest checkpoint

- Progress/summary panel now shows a Formats row with the selected merged
  formats, and the success banner lists every output folder a multi-format
  merged run creates (one line per format) instead of only the last one.
- Merged format selection is seeded from the active run, so navigating away
  and back (or switching method cards) no longer resets it to 16-bit.
- GGUF / Llama.cpp now offers an Export target toggle (Full model or LoRA
  adapter) for adapter checkpoints, reusing the LoRA GGUF export path.
- Removed the Auto GGUF LoRA output type and defaulted to Q8_0 in the UI,
  the request model, and the backend defaults; the outtype list is now
  Q8_0/F16/BF16/F32. Core save.py still accepts auto for external callers.
- When a finetune has no checkpoint selected, auto-select the newest one.

* Studio torchao export: robust reload class + optional VLM import

Two fixes to the portable torchao FP8/INT8 export reload, from review of the
narrowed VLM detection:

- Encoder-decoder seq2seq checkpoints (T5/BART/Whisper) are not causal LMs.
  With the narrowed is_vlm test they now correctly skip the image-text class,
  but fell through to AutoModelForCausalLM and failed to reload after the merge.
  Reload them with their own architecture class from the config instead.
- AutoModelForImageTextToText was imported unconditionally at the top of the
  torchao path, so on Transformers builds without that class the import aborted
  every torchao export (even text-only). Import it lazily only for a VLM, with
  the AutoModelForVision2Seq fallback used elsewhere in Unsloth.

* Studio: enable FP8/FP4 compressed export for newer-transformers models

The shipped llm-compressor 0.10.x pins transformers<=4.57.6, so FP8/FP4 export failed
for models needing a transformers 5.x sidecar (Qwen3.5, Gemma-4, Qwen3-Next): the
quantization subprocess crashed importing the removed TORCH_INIT_FUNCTIONS.

Run the quantization against a dedicated llm-compressor-main "shadow": a --target
package dir (transformers 5.10.2 + llm-compressor main + compressed-tensors) layered
over the existing torch. It installs --no-deps so torch is never touched (works on any
Studio torch build), is provisioned lazily and fingerprint-cached, and can be turned
off with UNSLOTH_DISABLE_LLMCOMPRESSOR_MAIN.

- transformers_version.py: provision + validate .venv_llmcompressor.
- export.py: route all compressed exports through the shadow when available; else keep
  the workspace 0.10.x path and fail fast past its transformers ceiling.
- save.py: launch _compressed_quantize.py with a clean PYTHONPATH = shadow.
- _compressed_quantize.py: skip linear_attn / vision tower / MTP modules (matches the
  RedHatAI and NVIDIA reference quants, and is required by the grouped schemes).

Verified all four schemes (fp8, w8a8, w4a16, mxfp4) on Qwen3.5-9B and Llama-3.2-1B, and
fp8 on Gemma-4, end to end through Studio.

* fix: unwrap MLX scheduler enum args

* fix: coerce integral MLX epoch counts

* fix: spoof CUDA compatibility APIs on MLX

* fix: harden MLX notebook compatibility shims

* MLX: add torch.cuda.mem_get_info to the compatibility shim

Notebook memory cells call torch.cuda.mem_get_info()[0] directly (not gated by
is_available), so on MLX it raises without a shim. Return (free, total) bytes
from the MLX device stats, consistent with the other torch.cuda compat helpers,
and add a matching assertion to the compat-API test.

* MLX: use active memory for mem_get_info; fix BatchEncoding.to keyword device

Address review on the MLX compatibility shim:
- torch.cuda.mem_get_info() now derives free bytes from current active MLX
  memory instead of the peak high-water mark, so a capacity check stays
  accurate after a transient spike or a prior run.
- BatchEncoding.to(device=...) passed by keyword no longer forwards a positional
  None alongside the keyword (which raised "multiple values for 'device'"), so
  non-CUDA keyword moves like .to(device="cpu") delegate correctly.

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* MLX: accept preserve_dataset_order; stub RL trainers with a clear error

Two fixes so unmigrated notebooks behave predictably on MLX (torch present):

- preserve_dataset_order is a real MLXTrainingConfig field but was missing from
  the extra-argument allowlist, so passing it (as a config or trainer kwarg)
  could be rejected as unknown on a zoo without the field. Add it to
  _MLX_IMPLEMENTED_EXTRA_ARGUMENTS so the documented no-shuffle path is reachable.

- GRPO/DPO/ORPO (and KTO/PPO/Reward) have no MLX trainer yet. Retarget the ones
  the installed trl exposes to a stub that raises a clear 'not supported on MLX'
  error instead of importing the real torch/CUDA trainer and crashing deep
  inside it. Only existing trainers are retargeted (no invented attributes),
  idempotent across re-imports.

* MLX: make RL-trainer stubbing import-safe; back current-memory APIs with active memory

Address review on the MLX shims:
- The RL-trainer stub loop probed trl with getattr(_trl, name), which triggers
  trl's lazy trainer import and pulls torch -- that can crash import unsloth on a
  torch-free MLX install just to check existence. Decide what to stub from
  trl.__all__ + already-materialized attrs (vars) instead; never resolve the real
  trainer. All trl trainer names are in __all__, so they are still stubbed (even
  torch-free), and the probe no longer imports torch.
- torch.cuda.memory_reserved / memory_allocated (the current, non-max APIs) were
  aliased to peak max_memory_reserved. Back them with current active MLX memory so
  cleanup / capacity checks see live usage; max_* keep the peak high-water mark.

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* MLX: keep TRL's SFTConfig epoch default under the trl.SFTConfig alias

Unmigrated notebooks import SFTConfig from trl, which the MLX build aliases to
the public training-args class. TRL/HF SFTConfig defaults to num_train_epochs=3
(max_steps=-1); the native MLX config defaults to max_steps=60. So an SFTConfig
built without an explicit length silently ran 60 MLX steps instead of TRL's 3
epochs under the alias. Alias trl.SFTConfig to a thin subclass that seeds the
TRL epoch default only when neither max_steps nor num_train_epochs is given;
explicit lengths pass through untouched, and the native public args class keeps
its MLX default. Epoch mode is supported by the MLX trainer.

* MLX CI: keep the GGUF reload smoke under the job timeout

The RELOAD-GGUF-via-llama-cli step timed out at 300s. BF16 GGUF decode is
CPU-bound on the macOS runner (~10s+/token), so generating 24 tokens landed
right on the 300s cliff and killed the process. This step is a save/reload
integrity smoke (it only needs a few chars of output), so the token count is
incidental: generate 8 tokens with explicit threads and a small headroom on the
subprocess timeout, all env-tunable (UNSLOTH_GGUF_RELOAD_N / _THREADS /
_TIMEOUT). Cuts the reload well under the 25 minute job budget.

* MLX: broaden trainer stubs, real peak-memory reset, fix shim tests

Address review on the MLX public API:
- The SFTConfig identity tests asserted trl.SFTConfig is UnslothTrainingArguments,
  but the alias now points at the _MLXSFTConfig subclass that preserves TRL's
  epoch default, so the MLX suite failed before testing the shim. Assert
  issubclass instead.
- torch.cuda.reset_peak_memory_stats was a no-op, so max_memory_reserved kept
  earlier model-load peaks across a scoped run. Wire it to mx.reset_peak_memory
  with the same core/metal fallback used for the reads.
- The unsupported-trainer stubs were a fixed list, so trainers outside it (a
  newer RLOOTrainer) still routed to the real torch trainer. Derive the set from
  trl.__all__ (every non-SFT *Trainer) so all non-SFT surfaces fail with a clear
  MLX message; names come from __all__ so trl is never resolved.
- The non-MLX export smoke skipped only on missing bitsandbytes/triton; other
  absent GPU deps (numpy/torch/unsloth-zoo, or _gpu_init re-raising ImportError)
  made it fail on CPU hosts. Skip on any ImportError.

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* fix: keep MLX notebook compatibility minimal

* MLX CI: force CPU + small context for the GGUF reload smoke

The RELOAD-GGUF-via-llama-cli step timed out even at 8 tokens (>420s), so it is a
fixed hang, not per-token cost: on the paravirtual macOS runner GPU llama.cpp's
Metal backend stalls, and the gemma3 GGUF advertises a 32768 context that llama-cli
would otherwise fully allocate. Run llama-cli CPU-only (-ngl 0) with a small context
(-c 256); keep generation short. All env-tunable (UNSLOTH_GGUF_RELOAD_NGL / _CTX /
_N / _THREADS / _TIMEOUT). Also print llama.cpp's partial stdout/stderr on timeout so
a future hang is diagnosable instead of an opaque TimeoutExpired.

* MLX CI: export the reload-smoke GGUF as q8_0, not bf16

The GGUF reload via llama-cli timed out on the runner even CPU-only with a tiny
context and 8 tokens. Root cause is the format, not the flags: the smoke exported
quantization_method='not_quantized', which maps to a bf16 GGUF, and llama.cpp's
bf16 CPU decode is unusably slow on the paravirtual macOS runner. Export q8_0
(fast_quantized, the exporter default and what users deploy) instead -- llama.cpp
has optimized q8_0 CPU kernels, so the fresh-process reload loads and generates in
seconds. The reload stays CPU-only (-ngl 0) with a small context.

* test: clear TRL shim before availability check

* Fix review issues for PR #6509: Cpu icon, VRAM percent, system polling

- model-inspector: use the exported CpuIcon (Cpu is not a Hugeicons export)
- app-sidebar: guard the VRAM percent on totalVram to avoid Infinity, and
  reset the system poll cache only after each request settles so a slow probe
  is reused instead of stacking overlapping requests
- use-gpu-info: populate CPU/RAM on hosts without a GPU
- progress-section: label GPUs by visible_ordinal instead of array index
- hub-page: base the RAM label on systemRamTotalGb
- usage-examples: emit JS sampling and tool options at the top level instead
  of nesting them under extra_body (the JS SDK does not unwrap extra_body)
- main: read torch and transformers versions from package metadata instead of
  importing the libraries on every system poll, and guard the VRAM math
  against null values
- hardware: translate a leftover comment to English

* Harden /api/system: guard psutil.boot_time for PR #6509

Simulating restricted containers and some VMs (where psutil.boot_time can raise)
showed the /api/system endpoint would 500 on the unguarded boot_time call, the
same failure class already handled for cpu_freq, disk_usage, and Process. Wrap
boot_time and return uptime_seconds as null when it is unavailable so the sidebar
monitor degrades gracefully instead of breaking. Widen the uptime_seconds type to
number | null to match.

* Studio: make the sidebar hardware monitor a toggle (default on) for PR #6509

Adds a "Show hardware monitor" switch under Settings > Appearance > Layout,
backed by a localStorage preference (default on), mirroring the existing
useSidebarPin pattern. When turned off, the sidebar hides the VRAM/RAM meters
and useSystemInfo stops the 3s /api/system poll entirely, so no nvidia-smi /
SMI probes run while the monitor is disabled. Adds the en and pt-BR strings.

* Studio: default the sidebar hardware monitor to off (opt-in) for PR #6509

* Studio pt-BR: fix three small translation defects for PR #6509

- learningRateDescription: "5e-5 for CPT" -> "5e-5 para CPT" (leftover English)
- exportScopeRecents: "Recents" -> "Recentes" (untranslated)
- relativeMonthsAgo/relativeYearsAgo: add the missing space ("há {count} meses"/
  "há {count} anos") so they no longer render as "há 3meses"

* Studio pt-BR: translate the last 10 fallback keys for PR #6509

Adds the settings.general.storage block (Armazenamento) and the
settings.chat.modelDisclaimer pair, so pt-BR now covers all en keys
(679/679) with no English fallbacks.

MLX CI: find llama-cli where save_pretrained_gguf actually installs it (#6777)
* MLX CI: find llama-cli where save_pretrained_gguf actually installs it

The GGUF reload step hardcoded the CWD-relative paths llama.cpp/llama-cli and
llama.cpp/build/bin/llama-cli, but save_pretrained_gguf builds and installs llama.cpp
under unsloth_zoo's LLAMA_CPP_DEFAULT_DIR ($UNSLOTH_LLAMA_CPP_PATH, else
~/.unsloth/llama.cpp), so the reload could not find the binary and failed the Mac M1
job with "llama-cli not found". _find_llama_cli now searches that install directory
(and honors the env override) before falling back to the old CWD layout, with a
recursive glob as a last resort. The search is a strict superset of the previous
paths, so it cannot regress a layout that already worked.

* MLX CI: return an absolute llama-cli path from the locator

Resolve the located binary to an absolute path. If UNSLOTH_LLAMA_CPP_PATH is a
relative directory (e.g. "."), Path(".") / "llama-cli" normalizes to the bare name
"llama-cli", and subprocess.run treats a separator-less argument as a PATH lookup
rather than a file to execute, raising FileNotFoundError. resolve() makes the returned
path absolute so it always runs the intended binary.

* MLX CI: give llama-cli EOF on stdin so GGUF reload cannot hang

With the binary now found, the GGUF reload actually invokes llama-cli and it timed
out after 300s generating 24 tokens on a 270m model, which is a stdin block rather
than slow generation: subprocess.run captured stdout/stderr but left stdin inherited,
so -no-cnv still left llama-cli waiting for interactive input. Pass
stdin=subprocess.DEVNULL so it receives an immediate EOF and runs the single prompt to
completion.

studio: explicit Cloudflare tunnel notice and public-exposure warning at startup (#6515)
* studio: announce Cloudflare tunnel state and warn about public exposure on startup

The startup banner only printed a line when a tunnel URL was up, so a plain
`unsloth studio -H 0.0.0.0` launch silently created a public trycloudflare.com
URL with no indication that Studio had become reachable from the internet. The
only hint at the tunnel was the CLI help, shown when an invalid command was typed.

Make the banner always state the tunnel state for wildcard binds:
- ON: the public URL plus a warning that anyone with it can reach Studio from
  outside the network, and that --no-cloudflare keeps it local-only.
- FAILED: requested but did not start (local network only).
- OFF: --no-cloudflare was passed (local network only).
Secure mode keeps its existing wording (the authenticated tunnel is intended and
--no-cloudflare is not valid there). Clarify the --cloudflare help text in both
the argparse and typer definitions. Default behavior is unchanged.

Also surface the state on the `unsloth studio run` banner, which runs the server
with silent=True and prints its own banner: it now calls _print_cloudflare_line
too, so the ON/OFF/FAILED notice and public-exposure warning are no longer
skipped on that path (previously it only echoed the URL when a tunnel was up).

For the OFF and FAILED notices, do not claim "local network only" when the
reachability probe just confirmed the raw port is reachable from the public
internet: --no-cloudflare and a failed tunnel disable only the Cloudflare link,
not the wildcard bind, so the message is reworded to flag the public raw port.

Studio: stop handing CI/user secrets to downloaded llama.cpp binaries (#6696)
* Studio: stop handing CI/user secrets to downloaded llama.cpp binaries

The macOS prebuilt path installs llama.cpp from the unslothai/llama.cpp
fork's latest (unpinned, mutable) release and then executes the
downloaded llama-server / llama-quantize binaries during install-time
validation. binary_env() built that child environment from a full
os.environ.copy(), so a compromised or tampered prebuilt would inherit
every secret in the process: HF_TOKEN and the workflow GitHub tokens in
CI, and HF / cloud credentials for end users running install.sh /
setup.sh.

We publish prebuilts daily, so pinning a release tag is not workable.
Instead, neutralise the impact: these binaries have no reason to read any
token, so strip secret-bearing variables (exact names plus
TOKEN/SECRET/PASSWORD/CREDENTIAL/PRIVATE_KEY/API_KEY markers) before
handing the env to a downloaded binary. The installer's own GitHub and
Hugging Face API calls read os.environ directly, so authentication and
release-API rate limiting are unaffected; PATH, LD_LIBRARY_PATH,
DYLD_LIBRARY_PATH and CUDA/ROCm vars are preserved. One change covers the
install-time validation path for all six macOS workflows and end users.

Follow-up (separate, sequenced): publish build-provenance attestations
from the fork's prebuilt workflows and verify them in CI, so a forged
release is rejected rather than merely starved of secrets.

* Strip KUBECONFIG, SSH_AUTH_SOCK, and PASSPHRASE-marked vars from binary env

Extend the deny-list per PR review: KUBECONFIG and SSH_AUTH_SOCK are
credential pointers/capabilities a downloaded binary never needs, and a
PASSPHRASE marker catches SSH_PASSPHRASE / GPG_PASSPHRASE. Tests updated.

* Studio: also scrub proxy/index env vars and URL-embedded credentials before running prebuilt binaries

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Scope mlx-ci secrets to the install + download commands for PR #6696

Drop the ambient step-level env block and pass GH/GITHUB/HF tokens only
on the installer and GGUF-download commands, so the directly invoked
llama-quantize / llama-server smoke runs see no secrets. The installer
still reads tokens from os.environ for the releases API and probe fetch.

* Trim verbose comments around the secret-env scrubber for PR #6696

Comment-only: condense the block comments added across this PR. Logic
unchanged (comment_tools.py check confirms code-only signature equal).

* Redirect HOME / cache pointers to an empty dir for prebuilt binaries (PR #6696)

Address Codex P2: stripping token env vars still let a tampered binary
read on-disk token stores (~/.cache/huggingface/token, ~/.aws/credentials,
~/.config/gh) through $HOME and the cache/config pointers. Point HOME plus
the HF / XDG / Windows home pointers at a single empty throwaway dir for
the downloaded-binary env. Defense in depth: a binary resolving the real
home via getpwuid is out of scope and needs OS sandboxing.

* Close residual credential-probe gaps for PR #6696

Address the latest Codex review:
- Strip token-only URL userinfo too (scheme://ghp_token@host), not just
  the user:pass form.
- Redirect HOMEDRIVE/HOMEPATH alongside USERPROFILE so a Windows binary
  cannot reconstruct the real profile from %HOMEDRIVE%%HOMEPATH%.
- Drop explicit credential-file pointers (NETRC, PIP_CONFIG_FILE,
  DOCKER_CONFIG, GIT_CONFIG_GLOBAL) that live outside HOME.
- Probe ldd with a secret-free env: linux_runtime_dirs ran ldd on the
  untrusted prebuilt with the inherited os.environ, and ldd may execute
  the binary, so it could observe HF_TOKEN/GITHUB_TOKEN during the probe.

Factored the shared scrub into secret_free_environ().

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Separate token-bearing install from binary smoke; drop CI command files (PR #6696)

Address the two P1s in the latest review:
- mlx-ci: GitHub bakes secrets into the run-script text, so inline token
  assignments in a step that later runs the prebuilt let a tampered binary
  read them from the script. Split into a token-bearing install + download
  step that never launches a binary, and a secret-free smoke step that runs
  llama-quantize / llama-server.
- secret_free_environ now drops the GitHub Actions command files
  (GITHUB_ENV, GITHUB_PATH, GITHUB_OUTPUT, GITHUB_STEP_SUMMARY, BASH_ENV) and
  the smoke step unsets them, so a tampered prebuilt cannot inject PATH/env
  into the later token-bearing MLX steps.

* Run the prebuilt smoke last, after all token-bearing steps (PR #6696)

Address the P1 workspace-poisoning vector: even with no secrets in its env,
a tampered prebuilt could edit the checkout or installed modules, and the
later HF_TOKEN MLX steps would then execute that poisoned code on push
builds. Move the prebuilt install + smoke to the end of the job so the
untrusted binary runs after every token-bearing step, leaving nothing for it
to corrupt. The MLX GGUF reload uses a source-built llama-cli, not this
prebuilt, so nothing depends on the earlier position.

* Trim comments around the secret-env scrubber and prebuilt CI steps (PR #6696)

Comment-only: condense the security-rationale block comments and merge the
duplicated prebuilt-step description in mlx-ci. Logic unchanged
(comment_tools.py check confirms the code-only signature is equal; install
suite still passes).

* Authenticate the GGUF export release-API lookup with the read-only GITHUB_TOKEN (PR #6696)

* Rename env scrubber off the secret-named identifier CodeQL flags as a clear-text sink (PR #6696)

Harden flaky Studio CI: retry VS-hide rename and tolerate same-URL nav interrupt (#6713)
Two intermittent Studio CI failures, both runner-environment flakes unrelated
to test logic:

Windows 'Studio install + inference without Visual Studio': the 'Hide Visual
Studio + CMake' step renames C:\Program Files\Microsoft Visual Studio to
simulate a host with no build tools. A background handle on a Program Files
directory (Defender scan or an MSBuild node) makes Rename-Item intermittently
fail with 'Access is denied', and $ErrorActionPreference = Stop turns that into
a hard job failure. Wrap the VS and cmake renames in both Hide steps in a short
Rename-WithRetry (6 tries, 3s apart) to ride out the transient lock.

macOS 'Chat UI Tests': the re-login goto to /login can be interrupted by the
SPA auth guard redirecting to the same /login URL, which Playwright reports as
'Navigation to .../login is interrupted by another navigation to .../login'.
The goto already tolerated ERR_ABORTED; broaden it to also tolerate the same-URL
interrupt (the password-field wait right after confirms we landed on /login),
and add the same signature to the two Playwright flake-retry harnesses as a
safety net for any other navigation.

Validated: playwright_chat_ui.py parses + byte-compiles, both workflow YAMLs
parse, bash -n on the retry harnesses, PowerShell AST parse on all pwsh steps,
and a functional check of Rename-WithRetry (succeeds, and rethrows after
exhausting retries).

fix: wrap unprotected evaluate() calls with robust_evaluate() to handle navigation context loss (#6677)
* fix: wrap unprotected evaluate() calls with robust_evaluate() to handle navigation context loss

Fixes PR #5911 - Playwright UI test error: 'Execution context was destroyed'

The test had several direct page.evaluate() and locator.evaluate() calls that
weren't wrapped with robust_evaluate(), which retries when navigation destroys
the execution context mid-operation.

Changes:
- Wrap picker_visible_text() evaluate in robust_evaluate()
- Wrap _bubble_count() evaluate in robust_evaluate()
- Wrap assistant text query in robust_evaluate()
- Wrap theme_item click evaluation in robust_evaluate()
- Wrap background color/theme query in robust_evaluate()

This ensures all execution context losses from concurrent navigation are
properly caught and retried with exponential backoff, preventing transient
failures in the UI test suite.

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* fix: revert robust_evaluate on theme_item.evaluate per Codex review

The theme_item.evaluate('el => el.click()') is side-effecting — retrying
after a context loss could double-toggle the theme. It's already inside
a 3-attempt try/except loop that handles click failures gracefully.

The other 4 changes (all read-only queries) remain wrapped in
robust_evaluate() since retrying them is safe.

* fix: wrap remaining chat UI evaluate

Consolidate the echo guard into a single leading-label check (now also

Verify DiffusionGemma visual-server binary against approved checksums (#6635)
ensure_diffusion_visual_server() downloaded the visual-server release
asset with the unverified download_file() and marked it executable,
bypassing the approved-checksum manifest that gates every other prebuilt
llama.cpp artifact. The backend later auto-discovers that binary and
launches it through DG_VISUAL_BIN, so a compromised or substituted
release asset could place attacker-controlled native code in the install
tree and have it executed under the Studio user.

Require the matched asset to be present in the approved checksum manifest
and download it through download_file_verified() with the published
sha256. A name-matching asset that is absent from the manifest is refused
rather than executed.

Add regression tests covering the verified-download path and the refusal
of an unapproved asset.

Pin isolated Node.js installer to committed sha256 digests (#6625)
* Pin isolated Node.js installer to committed sha256 digests

The isolated Node installer verified each downloaded archive only against
SHASUMS256.txt fetched from the same nodejs.org origin as the archive, so a
compromised CDN or TLS path could serve a malicious archive plus a matching
checksum and gain code execution when the extracted node is run during the
npm floor check and version probe.

Anchor trust in studio/node_prebuilt_pins.json, a committed manifest of
per-arch sha256 digests, and verify archives against it. The default channel
installs the pinned version and never fetches the remote SHASUMS. Unpinned
lts, latest, or explicit versions fail closed via UnpinnedNodeRefused unless
UNSLOTH_NODE_ALLOW_UNVERIFIED=1, and the refusal is not swallowed by the
keep-existing-on-transient-failure path. Ship the manifest in package-data.

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Address review nits on the pinned Node installer

- Drop the unused npm_min_major field from node_prebuilt_pins.json; the floor is
  the NPM_MIN_MAJOR module constant and the dead field could silently drift.
- Reword the unpinned-refusal message so it does not tell a user already on the
  default to install it, and point the "add a pin" hint at the exact asset.
- Decode the opt-in SHASUMS body with errors="replace" so a non-UTF8 response
  yields a clean PrebuiltFallback instead of an uncaught UnicodeDecodeError.
- Tests: assert the refusal message (guards the main() catch order, not just the
  exit code), cover malformed-manifest parsing, and drive the opt-in remote-SHASUMS
  path end to end through install_prebuilt.

* Tighten comments in the pinned Node installer

Collapse multi-line rationale comments to single lines, drop docstrings on the
obvious internal helpers (load_pins, pinned_sha256), and shorten the manifest
note. Comments/docstrings only; verified code-unchanged via AST comparison.

* Address Codex review: verify pins on existing installs; tomllib fallback

- existing_install_matches now takes an expected_sha and the short-circuit passes
  the committed pin, so a version-matching but non-pinned or tampered install (e.g.
  from the old remote-SHASUMS path) is re-verified instead of kept. An unpinned
  target without opt-in no longer short-circuits on an existing install; it falls
  through to the UnpinnedNodeRefused fail-closed path.
- The package-data test uses pytest.importorskip(tomllib/tomli) so it does not
  ModuleNotFoundError on the supported 3.9/3.10 interpreters.

* Make the transient-failure keep-existing path pin-aware

The previous commit added the pinned-digest check to the existing-install
short-circuit but not to the post-download-failure fallback, which still kept any
runnable same-version install via existing_install_usable(). A same-version
install whose recorded sha256 is not the pin could therefore be kept on a
transient download failure, the exact artifact the short-circuit rejects. Refuse
to keep a same-version pin-mismatched install there too; a different usable
version is still kept for offline resilience.

* Bump pinned default Node to the current 24 LTS (24.18.0)

Node 24 LTS moved to 24.18.0; since the default channel now resolves straight to
the manifest, a frozen 24.17.0 would downgrade fresh installs and make
UNSLOTH_NODE_VERSION=lts refuse the current LTS as unpinned. Update default_version
and all six per-arch digests (verified against the official SHASUMS256.txt), and
point the test INDEX/short-circuit fixtures at the new LTS.

- Quote bare unquoted string values in Gemma native tool-call args (e.g.
  {location:Tokyo,unit:celsius}) so they parse; JSON scalars stay typed.
- Stop _detect_safetensors_features from suppressing supports_tools for
  templates that emit Gemma native <|tool_call>, which the shared parser
  now reads.
- Add tests for both.

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Harden Gemma tool-call parsing and stream-error detection

Address three issues in the Gemma-native tool-call path:

- _quote_gemma_object_keys stopped a bare (unquoted) string value at the
  first comma, so an argument like `location:New York, NY` was split
  mid-value and the synthesized JSON failed to parse, dropping the whole
  tool call. A bare value now ends only at `}` or a comma that begins the
  next `key:` pair.

- parse_tool_calls_from_text scanned the entire response for Gemma markers
  even inside a tool call already parsed from a `<tool_call>{...}` JSON
  block, so a marker-like string inside an argument (data) was promoted to
  a second, unintended tool call. Matches inside an already-consumed call
  span are now skipped.

- _openai_passthrough_stream relied on _monitor_openai_sse_line to flag a
  stream error, which returns early when monitor_id is None
  (skip_api_monitor), so an upstream error chunk left saw_stream_error
  unset and the synthetic-finish guard emitted a successful finish_reason
  after a failed stream. Error chunks are now detected independently of API
  monitoring.

Adds tests/test_gemma_tool_parse_edge_cases.py covering the comma and
marker-injection cases.

* Emit the terminal finish_reason chunk in GGUF streams

The OpenAI chat-completions GGUF tool stream and plain stream both built a
final ChatCompletionChunk carrying finish_reason but never yielded it, so
clients received the optional usage chunk and [DONE] with no chunk carrying
finish_reason. OpenAI-compatible consumers rely on that terminal choice to
distinguish stop/length/tool_calls. Yield it before the usage chunk and
[DONE], matching the other streaming paths.

* Parse tool calls in document order and skip nested markers both ways

Unify the JSON- and Gemma-format tool-call passes into a single
position-ordered scan:

- Calls are now emitted in byte order across both formats, so a mixed
  output like `<|tool_call>call:create{...}<tool_call|> ... <tool_call>
  {"name":"read",...}</tool_call>` executes create before read, matching
  the order they appear in (tools run in returned order).

- A candidate that starts inside an already-accepted call's span is
  skipped, in both directions: a JSON marker inside a Gemma argument and a
  Gemma marker inside a JSON argument are treated as data, not promoted to
  a second executable tool call.

Extends tests/test_gemma_tool_parse_edge_cases.py with the ordering and
JSON-in-Gemma nesting cases.

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Quote bare Gemma array elements; order finish before trailing usage

- _quote_gemma_object_keys skipped array values, so a Gemma call with a
  bare-string array argument like labels:[bug,ui] produced invalid JSON and
  the whole tool call was dropped. Array values are now scanned and bare
  string elements quoted, while numbers, quoted strings, and JSON literals
  are preserved.

- In the OpenAI passthrough stream, a trailing usage-only chunk
  (stream_options.include_usage) that arrived before any finish chunk was
  relayed before the synthetic finish, producing usage -> finish -> [DONE].
  Emit the synthetic finish before that usage chunk so the order matches the
  other streams (finish -> usage -> [DONE]).

Extends tests/test_gemma_tool_parse_edge_cases.py with the bare-array cases.

* Harden Gemma array parsing, XML-parameter guard, and stream teardown

Address five review findings on the Gemma tool-call and OpenAI passthrough
streaming paths:

- parse_tool_calls_from_text collected JSON and Gemma markers without the
  _inside_open_parameter guard, so a marker embedded in an existing
  <function=...><parameter=...> value was promoted to a separate tool call.
  Candidates that start inside an open XML parameter are now skipped, matching
  the guard the XML-style parser already applies.

- _quote_gemma_array_elements preserved array elements starting with { or [
  verbatim, so an array of objects (items:[{path:a}]) or a nested array failed
  json.loads and the whole call was dropped. Object and nested-array elements
  are now normalised recursively.

- _openai_passthrough_stream synthesized a finish chunk before a trailing
  usage-only chunk and set saw_finish_reason, which made the EOF guard skip the
  [DONE] sentinel. The EOF path now emits [DONE] whenever the upstream omitted
  it, even after a finish chunk was already synthesized.

- /generate/stream drove generation through asyncio.to_thread with no
  disconnect watcher, so a client disconnect during a long generation went
  unnoticed until the next send. It now runs _await_disconnect_then_cancel
  against the request, matching the other local streaming endpoints.

- _SameTaskStreamingResponse closed the body iterator with aclose() on a
  send-side disconnect, raising GeneratorExit so the generators' cancellation
  handlers (which finish the api_monitor entry) never ran. It now throws
  CancelledError, falling back to aclose() when athrow is unavailable.

Extends tests/test_gemma_tool_parse_edge_cases.py with array-of-objects,
nested-array, and marker-inside-XML-parameter cases.

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Watch disconnects on Anthropic streams; keep timestamps in Gemma values

Two follow-ups on the streaming and tool-parse paths:

- _anthropic_tool_stream and _anthropic_plain_stream drove generation through
  asyncio.to_thread(next, gen, ...) and only polled is_disconnected() between
  events, so a client disconnect during prefill or a long generation/tool step
  held the decode slot until the next event or a failed send. Both now run the
  _await_disconnect_then_cancel watcher used by the other local streams, stop it
  in finally, and break promptly when cancel_event is set.

- _GEMMA_NEXT_KEY_RE treated any comma followed by word-chars-then-colon as the
  next key, so a bare value such as "meet at 10:00, 11:00 tomorrow" was split
  into bogus keys. The next-key token must now be identifier-shaped (start with
  a letter or underscore), so a comma before a timestamp, ratio, or other
  numeric-then-colon text stays part of the value.

Adds a timestamp-in-bare-value regression test.

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Guard nested markers, reset on disconnect, clean unstarted streams

Three follow-ups on the tool-parse and streaming paths:

- parse_tool_calls_from_text only skipped markers that fell inside a span it
  had already parsed successfully, so when an unquoted Gemma argument contained
  a literal marker (code:<|tool_call>call:terminal{...}<tool_call|>) the outer
  object failed to normalize, its span was never recorded, and the inner marker
  was promoted to a standalone terminal call. Candidates nested inside any other
  candidate's brace span are now skipped regardless of whether the enclosing
  candidate parsed, so a marker in malformed outer data is never executed.

- /generate/stream skipped backend.reset_generation_state() when the disconnect
  watcher set cancel_event between chunks: the loop broke and the finally's reset
  is guarded on cancel_event being unset. A subprocess backend kept decoding
  after the client left. The cancel-break path now resets the backend.

- _SameTaskStreamingResponse threw CancelledError / called aclose() on the body
  iterator on a send-side disconnect, but neither runs the try/finally of a
  generator that never started (early disconnect on http.response.start), so the
  passthrough's eagerly-opened upstream httpx stream and cancel-registry entry
  leaked. It now tracks whether the body started and, when it did not, runs an
  optional unstarted_cleanup hook; the OpenAI passthrough wires it to close the
  upstream resp/client and exit the cancel tracker.

Adds a nested-unquoted-marker regression test.

studio: fix sentence-transformers RAG embedder on Windows ROCm (torchao) (#6608)
torchao has no working Windows ROCm build. transformers.quantizers imports it,
and it loads torch's c10d distributed backend at module level, which the AMD
Windows wheels omit (no RCCL). The import aborts, transformers can no longer
expose PreTrainedModel, and the sentence-transformers embedder silently falls
back to the llama-server GGUF embedder. Linux ROCm and NVIDIA are unaffected
(the c10d ops are present / torchao is real there).

The training and export workers already install the shared torchao stub before
importing transformers, but the RAG embedder runs in the main backend process,
which never did. Two fixes, both no-ops off Windows ROCm:

- embeddings.py: install_torchao_windows_rocm_stub() before the first
  sentence-transformers import, so an already-installed torchao is neutralized
  (fixes existing venvs).
- install_python_stack.py: stop installing torchao on Windows ROCm; it can only
  crash on import there, so new venvs never ship it.

Add tests covering the embedder stub call and the install skip.

studio/setup.sh: guard empty CUDA arch detection in the source build (#5854) (#6481)
* studio/setup.sh: guard empty CUDA arch detection in the source build

PR #5826 hardened setup.sh for fresh CUDA toolkits, but the source build
still set -DCMAKE_CUDA_ARCHITECTURES only when nvidia-smi reported a
compute capability. When that query returns nothing the build proceeded
with no explicit arch list, so llama.cpp built PTX only. On a driver older
than the toolkit that binary fails at runtime with "the provided PTX was
compiled with an unsupported toolchain" - the build succeeds, so neither
the build-time check nor the CPU fallback caught it (issue #5854).

Resolve the arch list before committing to a CUDA build. A new pure helper
_resolve_cuda_archs parses and de-duplicates the nvidia-smi compute_cap
output and honors an explicit UNSLOTH_LLAMA_CUDA_ARCHS override. When the
result is empty, build CPU llama.cpp instead of a PTX-only binary, with a
clear message pointing at the override - so the user still ends up with a
working llama-server. The override also lets advanced users force a native
build on hosts where nvidia-smi cannot report compute_cap.

No behavior change when an arch is detected: -DGGML_CUDA=ON plus the arch,
CUDA flags and NVCC_PREPEND_FLAGS are assembled exactly as before.

Adds tests/sh/test_resolve_cuda_archs.sh (single/multi/dedup/empty/garbage/
whitespace/override cases), wired into tests/run_all.sh and the
studio-backend-ci.yml shell-test loop.

* studio/setup.sh: resolve nvidia-smi via /usr/bin fallback for arch detection

Addresses review feedback on the empty-CUDA-arch guard: _setup_has_usable_nvidia_gpu
classifies a host as NVIDIA-usable using nvidia-smi on PATH OR /usr/bin/nvidia-smi,
but the new arch detection probed only `command -v nvidia-smi`. On a GPU host where
nvidia-smi is off PATH (reachable only at /usr/bin), arch detection returned empty
and the new empty-arch branch dropped the build to CPU, losing CUDA. Mirror the same
PATH-then-/usr/bin resolution so those hosts still get a native CUDA build.

Also scope _resolve_cuda_archs locals with `local` (no behavior change; it already
runs under command substitution).

* tests: update compute_cap-probe assertion for $_smi_bin resolution

The nvidia-smi /usr/bin fallback parameterized the binary in the compute_cap
probe (_setup_run_smi "$_smi_bin" ...), so the literal-string assertion in
test_compute_cap_probe_timeout_wrapped no longer matched. Assert the probe is
preceded by _setup_run_smi (timeout-wrapped) instead, scanning all occurrences
so the comment mention is ignored. Same intent, binary-agnostic.

* tests: ruff-format the compute_cap probe assertion (pre-commit)

Collapse the backslash-continued assert onto one line and normalize slice
spacing so the ruff-format pre-commit hook (0.6.9) is satisfied. Formatting
only; no behavior change.

* Tighten code comments (no logic change)

* studio(windows): build CPU when CUDA arch is undetectable (#5854)

The Windows source build added -DGGML_CUDA=ON unconditionally but only set
-DCMAKE_CUDA_ARCHITECTURES when $CudaArch was detected. With no detectable
compute capability that produced a PTX-only binary, the same hole the Linux
fix closed. Build CPU llama.cpp in that case, and honor UNSLOTH_LLAMA_CUDA_ARCHS
to force a CUDA build, matching setup.sh. Detected-arch builds are unchanged.

* test: anchor NVCC_PREPEND_FLAGS scope check on the final CPU branch

The undetectable-arch CPU fallback adds an earlier -DGGML_CUDA=OFF, so the
ordering check now anchors on -DGGML_CUDA=ON and the last -DGGML_CUDA=OFF
instead of the first.

The llama.cpp update banner is a fixed bottom-right toast (z-9998). When an
update is available it overlaps the composer's Send button and its subtree
intercepts the click, so send_and_wait times out (flaky; surfaces on the
Windows studio UI smoke, passes otherwise). Snooze the banner if it is
showing before each send, then wait for it to detach.

Windows installer: fix DiskPart UAC mid-install, drive-root cache, and spurious unsloth.exe rename warning (#6296)
* Windows installer: fix DiskPart UAC, drive-root cache, spurious rename warning, CPU-base messaging

amd-smi gate (DiskPart UAC mid-install): the AMD torch wheel ships hipInfo.exe
inside the venv, and the bitsandbytes fix prepends that venv Scripts dir to PATH.
shutil.which("hipinfo") then found it and flipped _amd_smi_allowed() to True, so
the post-install AMD probe fell through to `amd-smi list` (the venv hipInfo failed
to report gcnArchName, which is why the arch came from the GPU-name table) and
amd-smi elevated, popping the DiskPart UAC. Fix: a hipinfo resolved inside the
active venv (sys.prefix) is the torch-wheel binary, not a HIP SDK, and must not
open the gate. Mirrored in install_python_stack.py, install_llama_prebuilt.py, and
backend utils/hardware/amd.py (the runtime VRAM poller had the same latent prompt).

TORCHINDUCTOR_CACHE_DIR: move from C:\tc to <StudioHome>\TORCHINDUCTOR_CACHE_DIR so
the inductor/Triton cache lives under the user's Studio home, not the system drive
root. Long paths are already enabled above so deep inductor paths still fit.

unsloth.exe rename: skip the rename (and its "pip may fail with WinError 32"
warning) when SKIP_STUDIO_BASE=1. In the install.ps1 flow base packages are not
reinstalled, so unsloth.exe is never rewritten; the self-rename only failed because
setup runs via unsloth.exe (the running launcher holds its own file). The
'studio update' flow still attempts it.

CPU PyTorch messaging: clarify that the CPU base is temporary and setup replaces it
with GPU ROCm wheels, and print an explicit "GPU ROCm PyTorch installed" line after
the AMD wheels land, so the log makes clear the final install is GPU-accelerated.

Adds two regression tests covering the venv-internal vs external hipInfo gate.

Verified end-to-end on a Strix Halo box (Radeon 8060S / gfx1151): install.ps1
--local from this branch completed exit 0 with no DiskPart prompt, no rename
warning, the cache under the Studio home, and "GPU ROCm PyTorch installed
(gfx1151)"; Studio then booted and detected "ROCm (HIP 7.13.99004) -- AMD Radeon
8060S Graphics".

* Windows installer: drop the unreliable unsloth.exe rename and its WinError 32 warning

setup.ps1 used to rename the running unsloth.exe out of the way before the
base-package upgrade so pip could replace it. That rename never actually
worked: setup runs *via* unsloth.exe, so renaming our own running
uv-trampoline launcher failed with a sharing violation (WinError 32) and only
printed a scary 'could not rename unsloth.exe; pip may fail with WinError 32'
warning on every Windows install and update.

It also was not needed. pip tolerates a running/locked console-script .exe: it
moves the old one aside and writes the new one. The base upgrade routes through
pip on Windows, so the upgrade succeeds (or, in the install.ps1 flow with
SKIP_STUDIO_BASE=1, the base is not touched at all) and unsloth.exe is left
intact either way.

Removing the rename block and its failed-install restore block removes the
false warning for all Windows devices in both the install and update flows.

* Windows installer: gate venv-internal hipInfo.exe in PowerShell amd-smi probe; harden venv path checks

Follow-up to PR #6296.

  inside the Studio venv when probing for a HIP SDK, so amd-smi no longer reopens
  the DiskPart UAC during install/update. Mirrors _path_inside_venv in the Python
  installers, which already do this.
- amd.py, install_llama_prebuilt.py, install_python_stack.py: normcase the venv
  containment check (Windows paths are case-insensitive) and run the
  HIP_PATH/ROCM_PATH candidate through it too.
- setup.ps1: fall back to a short TORCHINDUCTOR cache dir when long paths are
  unavailable, and create the dir wildcard-safely.
- tests: isolate sys.prefix in the gate helper, add HIP_PATH/ROCM_PATH cases, and
  assert the PowerShell venv exclusion.

* Windows installer: install ROCm PyTorch directly for a known AMD arch

When the GPU arch is known (name-inferred from the GPU-name table) but ROCm
could not be probe-verified (no HIP SDK, no amd-smi), the bootstrap installed
a CPU PyTorch base that setup.ps1 then force-reinstalled as ROCm. The
repo.amd.com wheels bundle their own runtime (no HIP SDK required), which
setup.ps1 already relies on, so the CPU base was a pure wasted download/install.

- Gate the ROCm index on a known arch, not only on probe-verified ROCm, so a
  mapped arch installs ROCm torch directly. Unmapped arches and no-GPU hosts
  still get CPU (unchanged).
- Fall back to a CPU base if the ROCm-index install fails, so a transient
  repo.amd.com outage does not abort the install (setup.ps1 retries ROCm).
- Correct the stale comment that claimed ROCm wheels need a confirmed HIP SDK.
- Add a regression test for the arch-based gate.

* Windows installer: correct the unsloth.exe rename-removal comment

The comment claimed the base upgrade 'routes through pip on Windows' and that
pip 'moves the old unsloth.exe aside, then writes the new one'. That is not what
the code does. install_python_stack tries uv first; on a locked launcher uv
aborts and falls back to pip, but the pip fallback strips --upgrade-package and
base.txt lists only bare unsloth/unsloth-zoo, so pip finds them already
satisfied and no-ops. The running unsloth.exe is left intact at its current
version either way. Reword the comment to describe the real uv-first /
pip-fallback-no-op behavior. No functional change.

* Windows installer: close two gaps in the venv-internal hipinfo exclusion

Review follow-up. The amd-smi/DiskPart gate could still reopen in two cases:

- setup.ps1 ran the HIP probe long before $VenvDir is assigned, so without
  VIRTUAL_ENV (the `unsloth studio update` path) $venvRoots was empty and the
  venv-internal hipInfo.exe was not recognized. Seed the venv root from
  UNSLOTH_SETUP_PYTHON and the default Studio home too (both installers).
- The HIP_PATH/ROCM_PATH candidate was accepted without the venv filter, so an
  env var pointing into the venv (AMD wheel) still set $HipSdkInstalled. Run
  Test-HipinfoIsVenvInternal on the candidate as well (both installers).

Extend the PS gate test to assert both. Both .ps1 parse clean; install tests
pass (the venv-internal / HIP probe coverage at 359 passed).

* Windows installer: correct the CPU-base message for arches with no ROCm wheels

After gating the ROCm index on a known arch, a mapped arch sets $ROCmIndexUrl
and installs ROCm directly, so it no longer reaches the "temporary CPU base"
branch. That branch is now reached only by a name-inferred arch with no ROCm
wheels (e.g. RDNA2 gfx103X), where setup.ps1 does NOT install ROCm. The old
text ("setup replaces it with GPU ROCm wheels ... the final install IS
GPU-accelerated") was therefore always wrong there. Say plainly that PyTorch
stays on CPU for this GPU.

* Windows installer: seed the venv-internal hipInfo check from a custom Studio home

Test-HipinfoIsVenvInternal seeded the venv root from VIRTUAL_ENV, VenvDir, the
setup python, and the default %USERPROFILE% path only. A standalone
`unsloth studio update` with a custom UNSLOTH_STUDIO_HOME (or STUDIO_HOME alias)
and none of those set would not recognize the venv hipInfo on PATH, reopening the
amd-smi/DiskPart gate. Seed the custom home too, in both installers, and assert
it in the gate test.

* Studio installer: resolve venv aliases and expand ~ in the hipInfo venv filter

Two review points on the amd-smi/DiskPart UAC gate:

1. _path_inside_venv compared os.path.abspath of sys.prefix and the hipInfo
   path, which does not resolve symlinks, junctions, or 8.3 short names. A venv
   reached through an aliased path then fails the check, so its bundled
   hipInfo.exe is mistaken for an external HIP SDK and amd-smi runs (the
   DiskPart prompt this fix exists to suppress). Switch to os.path.realpath in
   all three copies (amd.py, install_llama_prebuilt.py, install_python_stack.py).

2. setup.ps1's early venv-internal hipInfo probe seeded the venv root from a
   custom Studio home (UNSLOTH_STUDIO_HOME / STUDIO_HOME) without expanding a
   leading ~, while the canonical resolver does. With a tilde form,
   [IO.Path]::GetFullPath kept the literal ~ relative to cwd, so the custom-home
   hipInfo escaped the filter and reopened the gate. Expand ~ in the probe the
   same way as the resolver.

tests/studio/install/test_pr5940_followups.py: 30 passed (adds a symlink
realpath case and a setup.ps1 tilde-expansion guard).

* Studio installer: mirror the hipInfo venv filter and ROCm wheel pins into install.ps1

Follow-up review on the same install.ps1 paths:

1. install.ps1's venv-internal hipInfo probe (Test-HipinfoIsVenvInternal)
   seeded the venv root from a custom Studio home without expanding a leading
   ~, unlike the canonical resolver and setup.ps1. A tilde form left
   [IO.Path]::GetFullPath with the literal ~ (relative to cwd), so the
   custom-home hipInfo escaped the filter and reopened the amd-smi/DiskPart
   gate. Expand ~ in the probe, matching the setup.ps1 fix.

2. The AMD ROCm path installed torchvision/torchaudio bare while pinning torch
   to below 2.12. AMD's per-arch index publishes the companions independently
   and may ship torchvision 0.27 (for torch 2.12) before removing 0.26, so a
   bare resolve can pick an ABI-incompatible set and fall back to CPU. Add
   torchvision/torchaudio floor maps and pass the pinned specs, mirroring
   setup.ps1 and install_python_stack.py.

3. The ROCm-to-CPU fallback torch install used Invoke-InstallCommand (no
   retry), the only torch step in the file without it. Switch to
   Invoke-InstallCommandRetry so the recovery path survives a transient index
   failure.

tests/studio/install/test_pr5940_followups.py: 33 passed (parametrized tilde
check over both installers, a torch/companion floor-map parity test, and a
CPU-fallback retry guard).

* Studio installer: scan all PATH hipinfo so the venv copy can't shadow a real HIP SDK

The amd-smi HIP-SDK probe used shutil.which("hipinfo") / Get-Command hipinfo,
which return only the first hit on PATH. The AMD torch wheel ships hipInfo.exe
inside the venv and the bnb fix (plus the Studio backend) prepend the venv
Scripts dir to PATH, so that venv-internal copy lands first. When a real HIP SDK
hipinfo sits later on PATH with HIP_PATH/ROCM_PATH unset, the first-hit probe
stopped at the venv copy, treated it as "not a HIP SDK", and closed the amd-smi
gate -- AMD users in that PATH-only SDK setup lost amd-smi telemetry and could
fall back to CPU. Scan every PATH entry and keep the first hipinfo that is not
venv-internal; only the venv copy is ignored, so the UAC/DiskPart suppression is
unchanged.

Applied to all three Python copies (install_llama_prebuilt.py,
install_python_stack.py, backend/utils/hardware/amd.py) via a new
_external_hipinfo_on_path helper, and both PowerShell callers (install.ps1,
setup.ps1) now use Get-Command hipinfo -All filtered by Test-HipinfoIsVenvInternal.

tests/studio/install/test_pr5940_followups.py: 36 passed (real-PATH scan tests, a
shadow-regression test for the exact venv-first ordering, and a parity check that
every Python copy uses the scanning helper).

* Studio uninstallers: fix leftovers (false "removed", shared icon, llama lock)

Auditing a dual native+WSL uninstall on a real device surfaced three leftovers:

1. uninstall.ps1 removed the data dir (which holds unsloth.ico) before the
   shortcuts that reference that icon, so Explorer's icon cache briefly held it
   open. Remove-Item -Recurse reported success yet left the locked file, and the
   dir was never re-attempted, so it orphaned with a false "removed" log.
   _RemovePath now verifies the path is actually gone (retrying transient locks)
   and reports honestly, and the data dir is re-swept after the shortcuts go.

2. install.sh writes a shared unsloth.ico to %LOCALAPPDATA%\Unsloth Studio for
   the WSL shortcut, but uninstall.sh never removed it, orphaning the icon (and
   dir) after a WSL uninstall. uninstall.sh now drops that icon and the dir when
   empty, in both the powershell.exe and drvfs-fallback paths.

3. ~/.unsloth/.llama.cpp.install.lock was never removed, so the rmdir of
   ~/.unsloth failed and the dir lingered. Both uninstallers now remove the lock.

Verified by running both uninstallers on a real dual install: device fully clean
(no install dirs, shortcuts, PATH/registry entries, shared icon, or lock left).

* install.sh: auto-route Strix Halo WSL to an existing Ubuntu 24.04

ROCm-on-WSL is the GPU runtime for Strix Halo and only targets Ubuntu
24.04. When the installer runs in a newer default distro (e.g. 26.04) it
cannot enable the GPU and silently falls back to CPU. If a 24.04 distro
already exists, re-run the install there and stop in the current one so the
GPU path is taken without the user having to know about the distro
requirement.

Runs before venv creation so the wrong distro is left untouched, guards
against re-route loops via UNSLOTH_WSL_REROUTED, leaves a working ROCm
distro alone (librocdxg present), and skips the GGUF-only / opt-out /
non-Strix cases. When no 24.04 distro exists we keep today's behaviour:
continue to CPU and print the `wsl --install Ubuntu-24.04` guidance, never
auto-downloading a distro.

Adds tests/sh/test_strixhalo_wsl_reroute.sh (hermetic: extracts the
function, rewrites its paths to fixtures, mocks wsl.exe) covering the full
decision matrix, wired into tests/run_all.sh.

* uninstall.ps1: keep shared unsloth.ico for a surviving WSL shortcut

A dual native+WSL install shares %LOCALAPPDATA%\Unsloth Studio\unsloth.ico:
install.sh points the WSL shortcut's icon there while the native install owns the
dir. The native uninstaller removed the whole dir unconditionally, so uninstalling
native while keeping WSL left the WSL shortcut with a blank icon. The old code only
avoided this when Explorer happened to hold the icon open, which is unreliable; on a
real dual install the dir was deleted and the WSL shortcut went blank.

_RemoveDataDirKeepingWslIcon now scans the Start Menu + Desktop for a surviving
"Unsloth Studio (WSL ...).lnk" and, if found, removes everything in the data dir
except unsloth.ico (keeping the dir) instead of deleting it; with no WSL shortcut it
removes the dir as before. uninstall.sh still drops the icon and the empty dir when
WSL itself is uninstalled, so every uninstall order ends clean.

Adds tests/studio/test_uninstall_dual_install_icon.ps1 (AST-extracts the helper and
runs it against a temp dir with controlled shortcut dirs) covering the dual,
native-only, empty, and missing-dir cases, wired into the windows-inference smoke
workflow. Verified on a real dual install: native uninstall now keeps unsloth.ico
and the WSL shortcut's icon stays intact.

* installer: condense AMD/ROCm code comments (no behavior change)

Tighten the comments added for the Strix Halo native+WSL installer work so
they are shorter and clearer without losing intent: the venv-internal hipInfo
amd-smi gate, the ROCm torch/companion floor maps, the WSL 24.04 reroute, and
the dual-install uninstall icon handling. Comment-only; code paths unchanged.
107 insertions, 166 deletions across 11 files.

* install.sh: run the Strix Halo WSL reroute before any STUDIO_HOME write

The reroute fired after mkdir -p "$STUDIO_HOME" and the legacy-venv migration,
so rerouting 26.04 -> 24.04 left an empty ~/.unsloth/studio stub in the origin
distro (and ran venv migration in the distro about to be abandoned). Move the
reroute ahead of the venv section so the origin distro is left untouched, matching
the function's own comment. Behavior is identical on every non-reroute path.

* installer: fix ROCm CPU-fallback, hipinfo gate edge cases, uninstall icon, WSL 22.04

- install.ps1: clear $ROCmIndexUrl/$ROCmTorchFloor after the CPU fallback so the
  flavor-repair block does not retry the failed ROCm index and abort the install;
  pin the ROCm companion specs ($visionSpec/$audioSpec) in the repair path too.
- install.ps1 + setup.ps1: skip a bare drive root in Test-HipinfoIsVenvInternal so a
  non-venv UNSLOTH_SETUP_PYTHON does not match the whole drive; iterate
  HIP_PATH/HIP_PATH_57/ROCM_PATH and take the first non-venv hipinfo.
- amd.py, install_llama_prebuilt.py, install_python_stack.py: strip surrounding
  quotes from PATH entries before probing for hipinfo.
- install.sh: pipefail the WSL reroute curl|sh; do not reroute supported Ubuntu 22.04.
- uninstall.sh: keep the shared unsloth.ico while any Unsloth shortcut (native or
  another WSL distro) still references it, in both the powershell and drvfs paths.
- tests: regression coverage for all of the above.

* installer: forward reroute options, guard ROCm bootstrap, harden hipinfo gate

- install.sh: forward the caller's --package/--python/--verbose/--tauri and a custom
  UNSLOTH_STUDIO_HOME into the WSL reroute (was a bare default install); bail on
  --local; run the reroute BEFORE dependency/uv install so the origin distro is left
  untouched; set UNSLOTH_SKIP_ROCM_WSL_SETUP after a failed reroute so the later
  ROCm-on-WSL bootstrap does not install into the unsupported origin distro.
- install.ps1 + setup.ps1: Get-Command hipinfo -CommandType Application so only real
  executables match (not an alias/function named hipinfo).
- uninstall.ps1: guard $env:APPDATA when building the default shortcut search dirs.
- tests: cover option forwarding, --local bail, the bootstrap guard, and the gate change.

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* installer: guard origin ROCm bootstrap on every CPU-only fallback; harden ~ expansion

WSL reroute: the no-wsl.exe, no-24.04-target and --local fallbacks all tell the
user the install continues CPU-only, but only the failed-reroute branch set
UNSLOTH_SKIP_ROCM_WSL_SETUP=1. The later _maybe_bootstrap_rocm_wsl gate keys off
that flag, so the other three branches could still install ROCm into the
unsupported origin distro (e.g. 26.04). Set the skip guard on all of them.

Forward UNSLOTH_ROCM_WSL_AUTO into the reroute so a Tauri/consented GPU bootstrap
carries through to the rerouted 24.04 child instead of dropping to the prompt path.

install.ps1/setup.ps1: guard the venv-probe ~ expansion on a non-empty
$env:USERPROFILE so Join-Path does not throw on a profile-less service account.

Tests: add no-wsl.exe and UNSLOTH_ROCM_WSL_AUTO reroute cases, the USERPROFILE
guard assertion, and route shell-test fixtures through a single trap-cleaned root.

* installer: pin + soften Windows ROCm Python repair, reroute to 22.04, harden gates

install_python_stack.py: the Windows AMD ROCm repair in _ensure_rocm_torch()
installed bare torch/torchvision/torchaudio via the fatal pip_install -- the same
asymmetry already fixed on the PowerShell side. A transient repo.amd.com failure
could abort the whole install even after install.ps1/setup.ps1 fell back to CPU.
Pin companions per-arch (gfx120X/Strix -> the rocm7.2 trio, mirroring the PS floor
maps) and make the retry nonfatal: keep the existing build and let the user re-run
update to retry ROCm, so the chain install.ps1 -> setup.ps1 -> stack stays CPU-safe.

install.sh: reroute now targets an installed Ubuntu 24.04 OR 22.04 (24.04 preferred);
both are AMD-supported for ROCm-on-WSL, matching the leave-alone set, so a box with
only 22.04 reaches the GPU instead of staying CPU-only.

install.ps1/setup.ps1: a bare ~ for UNSLOTH_STUDIO_HOME left an empty Join-Path child
(PS 5.1 throws); fall back to USERPROFILE directly and only join a real remainder.

_path_inside_venv (amd.py + both installers): guard a root-dir sys.prefix so commonpath
can't classify every path on the drive as venv-internal (defensive; venv never at root).

uninstall.sh: guard an empty LOCALAPPDATA in the PS-interop icon cleanup (mirror APPDATA).

Tests: add 22.04-target reroute cases, Windows ROCm pin+nonfatal coverage (text +
behavioral), root-dir guard coverage, and bare-~/LOCALAPPDATA guard assertions.

* install.sh: match WSL reroute target by exact distro name, not substring

The 24.04/22.04 reroute target was chosen with grep -F (substring), so a custom
distro such as 'Ubuntu-24.04-test' (with no exact Ubuntu-24.04) was picked as the
target; the later 'wsl -d Ubuntu-24.04' then fails and the Strix Halo install stays
CPU-only. Match whole lines (grep -ixF) and reuse the matched name so only a real
Ubuntu-24.04/22.04 is targeted. Adds substring-rejection + exact-vs-custom tests.

* install.sh: keep the WSL reroute target to Ubuntu 24.04 (helper-supported only)

The ROCm-on-WSL bootstrap (scripts/install_rocm_wsl_strixhalo.sh) dies on any
VERSION_ID other than 24.04 and pins the noble repo, so treating 22.04 as
GPU-supported let the parent report a successful reroute while the child fell
back to CPU. Drop 22.04 from the supported set and the reroute target list;
24.04 stays the sole target (keeping the exact whole-line distro match). An
already-working ROCm on any other version is still left alone by the librocdxg
check above.

tests: reroute 22.04 cases updated to the 24.04-only behavior; make the
"no wsl.exe" case hermetic so a real host wsl.exe can't leak in on dev boxes;
stop the tauri exit-order check from mis-flagging the reroute helper's
[ "$TAURI_MODE" = true ] && ... --tauri one-liner.

* installer: tighten comment wording across the Strix Halo install/uninstall paths

Condense the verbose multi-line comment blocks (amd-smi hipinfo gate, ROCm
torch install + CPU fallback, WSL reroute, uninstall icon-keep) into fewer,
clearer lines. Comments and a few docstrings only; no code, logic, or
behavior change. Verified with bash -n, the PowerShell parser, and ast.parse,
and the installer test suite still passes.

* add AGPL-3.0 SPDX headers to the .sh/.ps1 scripts missing them

Every shell and PowerShell script under the Studio/installer surface now
carries the standard SPDX-License-Identifier: AGPL-3.0-only + copyright
header (after the shebang where present): the installer (install.sh,
install.ps1), build.sh, the .github and src-tauri scripts, the installer
test suite, and the moe kernel test. Header-only, line endings preserved;
bash -n, the PowerShell parser, and the installer tests all pass.

* installer: drop the duplicate AGPL header from install.sh and install.ps1

Both already carry an SPDX-License-Identifier: AGPL-3.0-only header below
their usage comment block; the prior header pass added a second one at the
top because it only scanned the first few lines. Remove the duplicate so each
file keeps a single original header.

* installer: force-reinstall CPU fallback torch; propagate Tauri NEED_SUDO from reroute

install.ps1/setup.ps1: when the AMD ROCm wheel install fails and we fall back to a
CPU base, force-reinstall the torch/vision/audio triplet. A failed ROCm install can
leave an unpinned ROCm torch (e.g. 2.10.0+rocm on gfx110X/gfx90a) that still
satisfies the CPU torch>=2.4,<2.11.0 range, so without --force-reinstall uv keeps the
ROCm build and only swaps the companions -- a mismatched venv the flavor-repair block
won't fix. setup.ps1 scopes the forced reinstall to the ROCm-fallback path
() so the genuine CPU-only install stays fast.

install.sh: the Strix Halo WSL reroute treated every nonzero child exit as a reroute
failure and fell back to CPU. In --tauri mode the child uses exit 2 ([TAURI:NEED_SUDO])
to ask the desktop app to elevate for the target distro; capture the child's exit code
and propagate exit 2 in Tauri mode (the child already printed the NEED_SUDO line)
instead of masking it. CLI mode still falls back to CPU on a generic failure.

Tests: reroute Tauri exit-2 propagation (and non-Tauri CPU-fallback) cases;
run_func now preserves the child exit code; force-reinstall assertions for both
PowerShell installers.

Note: codex's _rr_q apostrophe finding is a false positive -- the helper already
emits POSIX-correct 'O'\''Brien' and round-trips under both sh and bash.

* setup.ps1: fix $cpuForce array collapse in the ROCm->CPU torch fallback

An if-expression assignment ($cpuForce = if ($ROCmCpuFallback) { @("--force-reinstall") })
collapses the single-element array to a scalar string, so @cpuForce splatting enumerated
it character-by-character into broken single-letter args (- - f o r c e ...), which made
uv/pip reject the install and aborted the whole Studio setup on the AMD ROCm->CPU fallback
path. Build $cpuForce as a real array assigned outside the if-expression so the splat passes
a single --force-reinstall arg. Genuine CPU-only installs stay fast (empty array, no flag).
Test now asserts the array-build form and rejects the if-expression form.

* uninstall: remove the isolated Node.js runtime (~/.unsloth/node)

The isolated Node.js runtime (install_node_prebuilt.py, added with the managed-Node
change) installs to ~/.unsloth/node in default mode -- a sibling of studio, so deleting
<studio> leaves it behind (~200MB orphaned after uninstall). Both uninstallers already
remove the other default-mode siblings (llama.cpp/.cache/.staging); add node alongside
them. uninstall.ps1 also adds it to the handle-lock sweep so a held node.exe can't block
the delete. Env/custom mode nests node under the custom root, removed with that root.

Studio macOS: faster startup, MLX self-heal, drop obsolete prebuilt pins (#6494)
* Studio: defer llama.cpp update probes and self-heal MLX on macOS

Two macOS startup problems shared one root area in the FastAPI lifespan:

- The llama.cpp capability + freshness probes ran inline before the server
  yielded, so a cold/slow/flaky network on the GitHub freshness check blocked
  'Application startup complete' (~34s on CI, longer in the field). Move both
  probes to a daemon thread; app.state stays None until ready (status routes
  already re-probe at request time). Opt out with UNSLOTH_DISABLE_UPDATE_CHECK=1.

- Train and Export were greyed out because mlx/mlx-lm/mlx-vlm arrive only
  transitively and a resolver backtrack silently drops them, so CHAT_ONLY stayed
  true. Add utils/mlx_repair.py: when Apple Silicon is detected without MLX,
  reinstall mlx/mlx-lm/mlx-vlm by name on a daemon thread and re-run hardware
  detection (opt out UNSLOTH_DISABLE_MLX_AUTOREPAIR=1). Surface a chat_only_reason
  in /api/health plus a sidebar tooltip so a greyed Train/Export explains itself
  instead of failing silently.

* Studio: guard model defaults against a None model name

load_model_defaults(None) called model_name.lower() with no guard, raising
'Error loading model defaults for None' before any model is selected. Return
an empty dict for a falsy/non-str name.

* Studio: drop obsolete upstream macOS + Windows Blackwell prebuilt pins

Both pins worked around gaps in ggml-org upstream prebuilts, but Studio now
routes every GPU host and all of macOS to the unslothai/llama.cpp fork
(published_repo_for_host), which ships the needed bundles, so both pins are
dead code on the default install path:

- macOS b9415: macOS always routes to the fork (its own macOS bundles), and
  host_supports_macos_minos() is the backstop. The pin only fired under an
  explicit --published-repo ggml-org override.
- Windows Blackwell b9360: Windows-NVIDIA routes to the fork, whose
  windows-x64-cuda13 bundle covers Blackwell (manifest max_sm 120, toolkit
  13.3), so the pin's self-disable check makes it dormant on every default
  install; it could only activate under the same upstream override on a
  13.0-13.2 driver.

Remove the pin constants, functions, and call sites. Keep the Blackwell
capability detection (_drop_blackwell_incapable_windows_cuda, _host_is_blackwell,
_windows_cuda_attempt_covers_blackwell) that still drops a non-sm_120 cuda-12.4
build on a Blackwell host. After this, an explicit --published-repo ggml-org
override on a Blackwell 13.0-13.2 host loses its GPU fallback and lands on CPU;
the default fork path is unaffected. Update the install selection-logic and
macOS-compat unit tests for the new no-pin behavior.

* Studio: walk back deeper on the macOS upstream prebuilt path

After removing the b9415 macOS pin, the explicit --published-repo ggml-org
upstream path still used the default 2-release fallback, so a pre-macOS-26 host
behind a run of macOS-26-only builds would exhaust two too-new plans (minos is
only checked post-download) and drop to a source build before reaching a
loadable older release. Walk back as deep as the fork macOS path
(DEFAULT_MAX_MACOS_RELEASE_FALLBACKS), turning the removed static pin into
dynamic discovery. Addresses review feedback on the macOS upstream fallback.

* Studio: pin transformers during MLX self-heal so it cannot break Studio

mlx-lm/mlx-vlm declare transformers>=5, but the single-env install pins
transformers==4.57.6. The self-heal used --upgrade with no constraint, so it
could upgrade transformers in the live venv and break the rest of Studio just to
make import mlx.core pass. Pin transformers to the installed version via a
constraint file: the resolver either finds an mlx build compatible with it or
fails (we stay chat-only), never upgrading transformers underneath Studio.
Addresses review feedback on the MLX repair install.

* Studio: harden MLX self-heal against an unsupported mlx-vlm

Pinning transformers alone made uv backtrack mlx-vlm to 0.3.9 (below unsloth-zoo's
mlx-vlm>=0.4.4), which imports but breaks VLM Train/Export -- so the self-heal
could clear chat-only onto a broken stack. Mirror the main installer: set
UV_OVERRIDE=overrides-darwin-arm64.txt so a current mlx-vlm coexists with the
transformers pin, require the same minimum versions unsloth-zoo declares, and
gate/validate on a full mlx_stack_available() check (not a bare import) so an
old or partial stack stays chat-only. Addresses PR review.

* Studio: filter Blackwell-incapable CUDA in resolve_upstream_asset_choice

resolve_upstream_asset_choice returned the first windows-cuda choice unfiltered,
so a Blackwell host could be handed an sm_120-incapable cuda-12.4 build while the
sibling planners drop it. Apply _drop_blackwell_incapable_windows_cuda here too
and fall through to the CPU bundle on a Blackwell host with no capable GPU asset.
Addresses PR review.

* Studio: re-poll health so MLX self-heal reaches an open UI

The sidebar cached the initial /api/health, so a successful background MLX
self-heal (chat_only flips false) did not re-enable Train/Export until a manual
reload. While chat-only for the recoverable mlx_unavailable reason, re-poll
/api/health and stop once Train/Export become available. Addresses PR review.

* Studio: make the disabled Train/Export tooltip reachable

The greyed Train/Export items pass a tooltip explaining why (e.g. MLX missing),
but a disabled <button> fires no pointer events and SidebarMenuButton only showed
tooltips while collapsed, so the explanation never appeared. Wrap a disabled
button in a focusable span and show its tooltip while expanded too; enabled items
keep the collapsed-only behavior. Addresses PR review.

* Studio: gate Train/Export on the full MLX stack, not bare mlx.core

detect_hardware enabled MLX training whenever `import mlx.core` worked, but the
MLX self-heal (utils/mlx_repair) treats a stack without mlx-lm/mlx-vlm at the
versions unsloth-zoo requires as inadequate. That asymmetry let the UI enable
Train/Export on exactly the partial/backtracked stack the self-heal is trying to
repair (greyed-in-but-broken VLM export). Gate on the same mlx_stack_available()
criterion so a partial stack stays chat-only (reason mlx_unavailable) and the
background repair restores it. Addresses PR review.

* Review fixes: isolate hardware-state test, robust transformers pin

- test_chat_only_reason.py: detect_hardware() assigns module globals directly,
  which monkeypatch does not revert; the autouse fixture now saves and restores
  DEVICE/CHAT_ONLY/CHAT_ONLY_REASON/IS_ROCM so a chat-only verdict here cannot
  leak into other backend tests (e.g. test_utils.py) on a GPU host.
- mlx_repair.py: read the transformers version from importlib.metadata instead of
  importing transformers, so the install pin is not silently dropped when
  transformers has valid metadata but fails to import.

* Fix CI: model full MLX stack in dispatch tests, keep selection test offline

dispatch (macOS) job:
- detect_hardware now gates MLX on the full stack (mlx_stack_available imports
  mlx_lm/mlx_vlm and checks dist versions), so faking only mlx.core makes the
  apple_silicon_mlx profile resolve to CPU. The dispatch tests assert the routing
  decision when the stack IS usable, so model a complete stack:
  test_hardware_dispatch_matrix patches utils.mlx_repair.mlx_stack_available and
  test_is_mlx_dispatch_gate patches hardware._has_usable_mlx_stack. The stack
  predicate's own internals stay covered by test_mlx_repair.py.

Repo tests (CPU) job:
- test_no_cuda_attempt_on_published_path_for_13_1 fell through to a live
  github_release_assets() upstream fetch after the Blackwell filter dropped every
  published attempt, which the offline security scanner blocks. Stub that fetch so
  the walk-back deterministically finds no usable CUDA build and raises
  PrebuiltFallback without network.

* Harden MLX self-heal: prepare transformers constraint inside the try

attempt_mlx_repair runs on a daemon thread, but _transformers_constraint_args was
called before the try. A failure there (e.g. tempfile.mkstemp on a full disk or a
bad TMPDIR) would propagate unhandled and silently kill the self-heal thread.
Move the call inside the try and initialize constraint_path so any such failure
is caught and leaves Studio chat-only instead of crashing the thread.

Update studio root-resilience tests for the inference-backend refactor (#6490) (#6553)
* Update studio root-resilience tests for the inference-backend refactor

#6490 moved the studio_root() probe and its (ImportError, OSError, ValueError)
handler out of _find_llama_server_binary / _kill_orphaned_servers into the shared
_resolved_studio_root_and_is_legacy() classifier, and switched the WSL ROCm lib-dir
ordering to lib_dirs.extend(_wsl_system_rocm_lib_dirs()). These source-introspection
tests still asserted the old inline structure, so they fail on main (surfaced by any
PR that trips the Repo tests path filter, e.g. the Windows installer PRs). Point them
at the new structure and assert the defense in its new home; no runtime change.

* Address review: qualify the classifier call and harden helper-body extraction

Assert the callers invoke LlamaCppBackend._resolved_studio_root_and_is_legacy()
through the class namespace (more precise than the bare name), and end the
helper-source slice at the next sibling def/decorator at the same indent instead
of the literal @staticmethod string, so a future docstring that mentions a
decorator can't truncate the helper mid-body and break exec().

Harden evaluate_fetch against execution-context-destroyed during navigation (#6549)
* Harden evaluate_fetch against execution-context-destroyed during navigation

The Mac Studio chat-UI Playwright test intermittently failed with 'Page.evaluate: Execution context was destroyed, most likely because of a navigation' (e.g. run 27904470348). evaluate_fetch already retried transport failures (the JS result status==0), but the page.evaluate call itself can throw at the Python level when a navigation or auth refresh destroys the execution context mid-call, which was uncaught and crashed the script.

Wrap the evaluate in a try/except that retries this transient class of error (execution context destroyed, frame detached, target closed) within the existing attempt budget, letting the page settle via wait_for_load_state before retrying. Real or persistent errors still propagate (re-raised on the final attempt or for non-transient messages).

* Add reusable robust_evaluate and route auth-token reads through it

Promote the execution-context-destroyed retry from evaluate_fetch into a reusable robust_evaluate(page_or_locator, expression, arg) helper, and have evaluate_fetch use it (no behaviour change to the transport retry). Route the post-login localStorage auth-token reads in playwright_chat_ui.py and playwright_extra_ui.py through it too, since those direct evaluates run right after auth redirects and are the same navigation-race class. The stable composer/IME evaluates that never overlap a navigation are left as-is. Helper retry semantics covered by unit checks (transient retries then succeeds, non-transient re-raises, persistent re-raises after the budget, locator settles via .page).

* Apply repo ruff-format kwarg-spacing to the hardened Playwright evaluates

* Don't replay single-use POSTs (auth/refresh) when robust_evaluate retries a context loss

* Match context-loss markers case-insensitively and only replay idempotent fetches

Playwright varies the casing of the detached-frame/destroyed-context error
across versions, so the substring check now lowercases both sides. evaluate_fetch
no longer replays mutating methods on a mid-call context loss: the default now
retries only GET/HEAD/OPTIONS, so a duplicate POST /api/inference/load (rejected
while the first is still loading) or a spent POST /api/auth/refresh is never
re-sent. Callers can still override per call.
