* Studio: stream live tool output with SSE heartbeats and fix web page extraction
Server-side python/terminal tools now stream incremental stdout to the chat
UI while running (new tool_output SSE event), and every blocking tool
execution emits heartbeat keepalives so reverse proxies (Cloudflare tunnels
cap idle streams at ~100s) cannot drop the connection mid-turn. The tool
loop routes also emit a stall keepalive during silent prompt prefill between
tool iterations. The final role=tool message the model sees is byte-identical
to before, so tool-call parsing, nudging, and healing are untouched.
web_search page fetches now extract main content: GitHub repo root pages are
rewritten to the README API (with HTML fallback), hidden/aria-hidden client
error placeholders are dropped, conversion scopes to article/main, and known
boilerplate fragments are stripped. Non-HTML responses are returned raw
instead of being run through the HTML converter.
The frontend renders live-scrolling tool output inside running python and
terminal cards, and a chat stream that ends without a terminal signal now
surfaces an explicit interrupted state with a Retry action instead of
silently ending the turn.

* Studio: fix content-type sniffing, unlimited-timeout drain, and env parity in tool streaming
Content-Type sniffing: get_content_type() defaults to text/plain when the
header is absent, so the sniffing fallback never fired and header-less HTML
came back as raw markup. Report an empty type for a missing header and sniff
the body whenever the declared type is not HTML, so mislabeled text/plain
HTML pages are converted like before the extraction change.
Unlimited timeout drain: with tool_call_timeout disabled the old path used
communicate(timeout=None) and waited for EOF, but the streaming drain capped
the post-exit drain at a 5 second join, truncating output from a grandchild
that holds stdout open. When timeout is None, drain until EOF or the cancel
event fires; finite timeouts keep the bounded remaining-budget join.
Env parity: drop the PYTHONUNBUFFERED=1 injection on the streaming path so
the child invocation is byte-identical with and without streaming (the env
var was model-visible via os.getenv). Live streaming granularity now depends
on the child flushing; unflushed output arrives in ~8 KB chunks or at exit
and the final result is unchanged, with SSE heartbeats covering the gaps.
* Studio: stream tool-call arguments while the model writes them
A model writing a large tool call (a full python game is minutes of
generation) produced nothing on the stream: the structured path
accumulated delta.tool_calls fragments silently after the provisional
card, and the text path's DRAINING state consumed everything until
stream end. The user saw a dead Running spinner while the model was in
fact writing code, and the byte-silent SSE segment was also the window
where proxies drop the connection.
New tool_args SSE events stream the arguments as they generate. The
structured path forwards each fragment once a provisional card exists
(backlog first, so the card starts from the top of the call). The text
path sniffs the drained call for an enabled tool name and streams the
raw call text under the id the stream-end parser assigns its first call
(call_0), so the final tool_start reconciles the same card; the sniff is
gated on enabled names plus the provisional size floor, and prose or
ordinary JSON answers never spawn a card. The safetensors loop streams
the drained render_html call to its existing provisional card the same
way.
The chat adapter accumulates the raw stream per card and feeds a partial
JSON parse (call envelopes and stringified arguments unwrapped) into the
part's args, so the python and terminal cards render the code live and
the render_html canvas builds while streaming; both cards now say
Writing code / Writing command during this phase via useToolArgsStatus.
Display only: the parser input, the executed call, and the conversation
the model sees are byte-identical, covered by new loop-level tests for
the structured path, the text path, and the no-tool JSON answer.

* Studio: keep full tool output visible past the model cap; heal /mnt/data habits
Live testing surfaced two issues in the tool streaming UX.
First, a long python stdout ended in '... (truncated' in the finished
card: the model-visible result is capped by tools._truncate
(_MAX_OUTPUT_CHARS, previously 8000 chars) to protect the context
window, and the card rendered that capped text even though the live
stream had already shown everything. The cap stays (raised to 16000,
overridable via UNSLOTH_TOOL_RESULT_MAX_CHARS) but display and model
concerns are now split: the adapter preserves the accumulated live
stream on tool_end whenever it captured more than the final result, and
the finished python/terminal cards prefer it. The live-stream ceiling
rises from 16 KB to 400 KB (chunks batch per poll, so SSE stays cheap),
and both the live pane and the finished card render only the last 2000
lines with a Show all control so a huge output cannot jank the DOM. The
truncation notice now tells the model the user saw the full output and
that written files persist in the working directory. The final result
string remains byte-identical with and without streaming.
Second, models trained on ChatGPT code-interpreter transcripts write to
/mnt/data, which does not exist here (the sandbox CWD is a per-thread
persistent dir). Three layers, all identical across streaming and
non-streaming paths: the python/terminal tool descriptions gain one
sentence saying to use relative paths in the persistent CWD; a failed
execution whose output shows a missing-file error on a known
code-interpreter prefix (/mnt/data, /mnt/outputs, /home/sandbox,
/workspace) gets a model-visible retry hint appended after truncation
so it always survives; and a sitecustomize shim on the sandbox
PYTHONPATH remaps those prefixes onto the CWD in open()/os.makedirs()
with a one-line stderr notice, covering the python tool and any Python
launched from the terminal tool without touching the exec wrapper (so
tracebacks keep their line numbers). Bash-level file operations cannot
be redirected without root or mount namespaces, so they rely on the
description and the hint.
* Studio: fix hidden-element parsing, heartbeat gaps, and tool output id collisions
Review follow-ups on the tool streaming work:
- _html_to_md: treat any present hidden attribute value as hidden (it is an
enumerated attribute whose invalid value default is the Hidden state, so
hidden="false" is still hidden), and implement HTML5 optional end tags so
an unclosed <p hidden> or <li hidden> ends at the next sibling start tag
instead of swallowing every following sibling until the parent closes
- tool_stream_exec: keep heartbeats flowing after the live-output cap; a
tool that keeps printing past the cap kept the queue non-empty, so neither
tool_output nor heartbeat events were emitted and the SSE stream went
silent past proxy idle timeouts
- routes/inference: forward tool heartbeats before the
disable_parallel_tool_use drop window swallows events, so a dropped call
that executes server-side cannot leave the Anthropic stream silent
- llama_cpp: close the provisional text tool card with a tool_end when the
drained call fails to parse (DRAINING false-positive path), so the card
cannot spin forever while the text is delivered as content
- tools: decode terminal output as utf-8 with errors=replace like the python
tool; invalid bytes used to raise UnicodeDecodeError from communicate() on
the non-streaming path and silently truncate the streaming reader, so the
two paths diverged
- sitecustomize: patch io.open alongside builtins.open; pathlib Path.open,
read_text and write_text call io.open directly and bypassed the remap
- frontend: scope the toolLiveOutput/toolFullOutput store keys by pane
(modelType and pairId) and clear stale entries on tool_start; backend ids
like call_0 repeat across turns and across concurrently streaming panes
(compare mode), so a later turn or another pane could display the wrong
preserved output, and run-end cleanup now clears only its own keys
Each backend fix carries a regression test that fails on the previous code;
the byte-identity tests between streaming and non-streaming stay green.
* Studio: keep tool failure status visible and truncation/remap notices truthful
Finished python/terminal cards preferred the fuller live stream by length
alone, so a tool that printed a lot then timed out or exited non-zero showed
the captured stdout but dropped the final result's status (timeout notice,
Exit code N). preferFullToolOutput now shows the stream when the result is
just its truncated prefix, and appends the result otherwise so the failure
tail always survives and the copy button copies both.
The result truncation notice claimed the user was shown the full output, but
the same wrapper serves non-streaming chat/API and direct execute_tool()
callers where nothing is streamed to anyone. The notice is now mode-neutral
and stays byte-identical with and without an output_callback, keeping the
streaming vs non-streaming invariant intact.
The sandbox sitecustomize shim now remaps /tmp/outputs into the working
directory only while it does not already exist, so a real /tmp/outputs the
user's own code created is never shadowed; /tmp/outputs also joins the
missing-path retry-hint list.
* Studio: suppress hidden void elements and keep live output scroll pinned only when at bottom
* Studio: drop capped tool output without concatenating; remap pathlib mkdir
Past the live-output cap stream_tool_execution built item + _drain_pending()
(the current chunk joined with every queued sibling) only to discard it in the
capped branch, so a chatty tool (yes, a tight print loop) could enqueue far
more than one poll interval of text and blow past the memory/CPU ceiling the
cap exists to enforce. Drain and drop queued items without building a combined
string, still counting each drain toward the heartbeat cadence so the SSE
keepalive survives.
Generated code often prepares code-interpreter paths with
Path('/mnt/data').mkdir(parents=True, exist_ok=True); pathlib drives that
through os.mkdir (not the patched os.makedirs) per component and, on
FileExistsError, probes the unpatched os.stat via Path.is_dir(), so the setup
raised before open() ever ran. Patch os.mkdir with the same remap and patch
Path.mkdir so the whole parents/exist_ok dance lands on the mapped working
directory and stays idempotent; real paths still pass through.

* Studio: generalize sandbox write remap and hint to any hallucinated absolute path
Models invent absolute paths from seeing their CWD (a DeepSeek run did
open('/home/ubuntu/Sandbox/flappy_bird.html', 'w') and died with
FileNotFoundError). A prefix list cannot enumerate these, so the sitecustomize
shim gains a write-mode fallback in open()/io.open(): when a write/create-mode
open targets an absolute path outside the CWD whose parent directory does not
exist, redirect it to the basename in the CWD and emit the same one-line stderr
notice, echoing the original path. The prefix remaps still run first (they cover
reads and preserve subpaths); read modes never hit the fallback so real system
files fail or succeed truthfully; bytes paths pass through. The fallback is not
applied to mkdir/makedirs/Path.mkdir, since creating an arbitrary absolute
directory can legitimately succeed on the host, and that decision is documented
in a comment.
The model-visible retry hint now echoes the real failing path (parsed from the
traceback tail) instead of the canned /mnt/data example, and fires for any
absolute path outside the working directory, not just the enumerated prefixes,
while a relative miss still gets no hint.
The shim wrapper still adds one frame to tracebacks that surface open() errors;
suppressing only our frame has no clean standard mechanism (a wrapper always
adds a frame), so the frame is left as an accepted compromise.
Tests: hallucinated absolute write remaps to the CWD basename across w/a/x/w+;
reads of a missing absolute path pass through untouched; writes to an existing
external dir pass through; prefix subpaths still preserved; end-to-end write
fallback lands the file in the sandbox workdir identically with and without
streaming; the hint echoes the actual path for convention and non-convention
absolute paths alike.
* Studio: kill exited process groups on drain; bound the over-cap output batch
_drain_process_output killed the process only via _kill_process_tree, which
short-circuits once the parent has exited, so a grandchild that inherited
stdout and outlived the parent was never signaled: a finite-timeout run could
return while it kept holding the pipe, and a timeout=None cancel left it
behind. Capture the setsid process group before waiting and SIGKILL that group
at both give-up points so the whole tree is torn down.
The streaming wrapper's first over-cap batch joined the current chunk with the
entire pending backlog before enforcing the live-output cap, so a chatty tool
could allocate far past the cap on the crossing batch. Bound the drain to the
remaining budget and drop the surplus in place, keeping the truncated output
byte-identical to joining everything.
* Studio: harden sandbox path healing and process/generator cleanup
Sandbox sitecustomize shim:
- Make the generalized write fallback collision-safe: never redirect an
invented absolute path onto an already-present CWD file (refuse and let the
original open raise FileNotFoundError, preserving the workspace file).
- Only w/a/x create a file; r+/rb+ are read-update modes that require the
target to exist, so a bare + no longer trips the write fallback.
- Gate every convention-prefix remap (/mnt/data, /mnt/outputs, /home/sandbox,
/workspace) on the prefix root being absent, so a real host mount is never
shadowed; a miss under an existing real prefix passes through.
- Patch os.open so Path.touch and other low-level creators heal convention
paths too, matching the Path.mkdir patch.
Local code execution (tools.py):
- Capture the setsid process group right after Popen (before any watcher can
poll/reap the leader) and thread it through the cancel watcher and drain.
- Kill the captured group in the non-streaming python/terminal timeout branch
so an exited leader no longer leaks a stdout-holding grandchild (matches the
streaming drain path).
- Guard os.getpgid/os.killpg by platform so streamed execution no longer
raises on Windows; fall back to single-pid kill.
- Judge missing-path hints against the executor's real workdir so a legitimate
miss inside a project workspace outside the sandbox root is not mislabeled.
Tool streaming routes (routes/inference.py):
- Drain a pending next(gen) worker before closing the generator in the
safetensors and Anthropic tool streams, so a disconnect no longer races
gen.close() (generator already executing) or leaks the thread/generator.
HTML to markdown:
- Only drop boilerplate lines composed entirely of known furniture phrases so
real prose that merely quotes one (for example "we use cookies to
authenticate requests") is preserved.
Adds hermetic tests for each change.

* Studio: keep aside callouts, contain sandbox path remaps, and keepalive dropped Anthropic tool events
_html_to_md: stop dropping <aside> unconditionally. Documentation pages
render notes/warnings/examples as aside admonition callouts; those inside
the selected article/main scope are real content. A furniture aside outside
the scope is already excluded by the main-content pass.
sitecustomize: contain the code-interpreter path remap under the sandbox
CWD. A hallucinated habit path such as /mnt/data/../other_session/file no
longer escapes the per-conversation workdir; parent-traversal components in
the suffix are dropped and a '.'/'..' write-fallback basename is refused.
routes/inference: emit a rate-limited comment keepalive when the Anthropic
Messages stream drops tool_output/tool_args events. A chatty tool keeps the
generator busy so the stall keepalive never fires and the tool wrapper emits
heartbeats only while idle, which left the SSE stream silent past proxy idle
caps; the OpenAI passthrough paths forward these events, this path now keeps
the connection alive.
* Studio: bound the tool-output chunk that first crosses the live cap
_drain_queue joined the entire chunk that first crossed the live-output
cap before dropping the rest, so a single multi-megabyte line (or any
chunk dequeued once the budget was already met at max_chars <= 0) was
materialized in full only to be truncated away, defeating the memory
ceiling the cap enforces. Slice the crossing chunk to one character past
the budget: that preserves the caller's overflow signal and its
byte-identical truncation while dropping the arbitrarily large remainder
in place.
* Studio: scope missing-path hint to the failing line, keepalive dropped-call output, and preserve truncated tool streams over byte length
- tools._missing_path_hint: the code-interpreter convention-prefix trigger
scanned the whole output, so a convention prefix mentioned only in a
traceback frame (a /workspace project root) or printed by the user's code
would add a misleading 'use a relative path' hint even when the actual
FileNotFoundError was a relative or in-workdir path. Scope the convention
test to the failing-path error line(s), matching _extract_missing_abs_path.
- _anthropic_tool_stream: the tool_output/tool_args rate-limited keepalive sat
after the drop_until_tool_end skip, so under disable_parallel_tool_use a
chatty second-or-later tool call was dropped whole with no keepalive, letting
an idle proxy kill the SSE stream. Check the keepalive branch before the drop
skip (like the heartbeat branch) so dropped-call output keeps the stream alive.
- preferFullToolOutput / chat-adapter: a truncated result can be longer than
the live stream by byte count once its footer, an 'Exit code N:' notice, or an
__IMAGES__ base64 tail is appended, so the length-only gate discarded the full
stream and the finished card fell back to the truncated text. Add a shared
truncation-aware shouldPreserveFullOutput used by both the write and read
sites: preserve the stream whenever the result carries the truncation footer.

* Studio: skip the habit-path hint for real project paths under a convention prefix
* Kill captured process group on streamed wait-timeout
The streamed drain path's proc.wait() timeout branch only called
_kill_process_tree(proc). If the leader exits in the narrow window between
the wait timing out and _kill_process_tree sampling its pgid, that helper
short-circuits on the reaped leader and a stdout-holding grandchild in the
same group survives. Also kill the captured pgid there, matching the
non-streaming communicate() timeout path. Adds a hermetic regression test
that models the reaped-leader race by stubbing _kill_process_tree.
* Fix 3.10 pathlib write_text remap and honor cancel in finite drain
On Python < 3.11 pathlib routes Path.open / read_text / write_text through
a module-level accessor singleton whose open attribute captured the original
io.open at import time (_NormalAccessor.open = io.open). Patching io.open in
the sandbox shim therefore never reached that captured reference, so a
Path('/mnt/data/x').write_text(...) raised FileNotFoundError on 3.10 while
passing on 3.11+ (which dropped the accessor and calls io.open at call time).
Repoint _NormalAccessor.open at the same io.open wrapper via a staticmethod,
guarded so it is an idempotent no-op on 3.11+. Keep the test save/restore
helpers symmetric so the accessor is restored too, and add a hermetic
write_text/read_text remap test that covers every version.
Also honor cancellation while draining inherited stdout after the leader
exits. Once the leader is reaped the cancel watcher returns (its loop is
while proc.poll() is None), so the finite-timeout drain did one blocking
reader.join(timeout=remaining) that ignored cancel_event and kept draining a
chatty grandchild for the whole budget after a disconnect/Stop. Poll
cancel_event in 0.5s slices against a deadline like the timeout=None branch
and kill the captured process group promptly on cancel. The normal path still
reaches EOF on its own, so the streamed vs non-streamed result is unchanged.

* Studio: port no-tool stream keepalive/drain and fix subprocess/queue/extraction asymmetries
Streaming no-tool paths now match their tool twins:
- _anthropic_plain_stream, safetensors/MLX no-tool stream, and standard GGUF
no-tool stream run next(gen) in a worker with a timed SSE keepalive loop so a
long prompt prefill cannot leave the stream idle past a proxy cap.
- The Anthropic plain and safetensors/MLX no-tool teardowns now drain the
pending next(gen) worker and close the generator on disconnect instead of
leaking the suspended generator.
Other asymmetries:
- Non-streaming _python_exec/_bash_exec always drain via _drain_process_output
(output_callback may be None) so a cancelled run reaps a stdout-holding
grandchild that outlived the leader instead of blocking in communicate(). The
joined bytes are identical to communicate(), so streamed vs non-streamed
results stay byte-identical.
- _build_bypass_env installs the sitecustomize path shim on PYTHONPATH (prepend,
keeping the operator's entries) so /mnt/data remap works in bypass mode too.
- GGUF forwards output_callback to execute_tool only when the callable accepts
it (shared accepts_output_callback), matching safetensors and preserving
legacy monkey-patched signatures.
- tool_stream_exec bounds accepted live output at the producer boundary so a
chatty tool cannot grow the queue without limit under consumer backpressure
and cannot keep the drain spinning and starve heartbeats.
- html_to_md implicit-close now searches past unclosed inline descendants so a
hidden <p>/<li> is closed by a following block; main-content scoping gates on
the largest single <article>/<main> so a swarm of tiny cards cannot pass the
threshold in aggregate and displace the real main.
- preferFullToolOutput re-attaches the "Exit code N:" prefix to the fuller
stream instead of appending the still-prefixed result, so a failed truncated
tool no longer duplicates its stdout in the finished card.
Adds hermetic tests for each.

tool_end (stream interrupted or cancelled) so the partial diagnostics

Anchor _looks_like_html to the leading doctype/tag so a Markdown README that

corruption), while bare HTML fragments (<body>/<article>/<section>) are still
detected and converted on a missing/wrong Content-Type.
Let the sandbox write fallback re-serve a target it already healed for the same
invented absolute path, so iterative overwrites of a generated artifact stop
failing with FileNotFoundError while the anti-clobber guard still refuses
unrelated same-basename files.
Reconcile the first textual tool call carrying an explicit id onto the open
provisional TEXT card instead of spawning a duplicate card under that id.

* Studio: run implicit-close before skipping tags and keep leading README tables as Markdown
A skipped block (<nav>/<footer>) is an HTML5 optional-end-tag closer of an
open <p>, but handle_starttag returned before the implicit-close bookkeeping,
so a never-closed <p hidden> kept its hidden mark and swallowed every following
sibling. Run _close_implicit before the skip decision so the hidden mark is
released and trailing content renders.
Drop <table> (and its <thead>/<tbody>/<tr>/<td>/<th> children) from the
_looks_like_html leading set: Markdown READMEs routinely open with a raw HTML
<table> badge/layout row, and sniffing that as HTML collapsed the whole
Markdown body through html_to_markdown, exactly like the already-excluded

The non-streaming _python_exec/_bash_exec now share _drain_process_output,
which reads proc.stdout in a reader thread and calls proc.wait(); the test
double only implemented communicate(), so bypass-mode bash returned an
AttributeError instead of the faked output. Give _FakeProc a readable stdout
pipe (yields the fake line then EOF), wait()/poll()/pid, so the test exercises
the real drain path on both the python and bash bypass branches.

* Studio: persist sandbox path heals across runs and suppress nested hidden lists
* Studio: run tool Python child unbuffered (-u) so unflushed prints stream live
A long-running snippet doing bare print() without flush=True never reached
the live-output pane: CPython block-buffers stdout when writing to a pipe, so
_drain_process_output's readline() saw nothing until the buffer filled or the
process exited. Launch the child with the interpreter -u flag so stdout is
unbuffered and each print streams as it is produced.
-u is applied unconditionally on both the streaming and non-streaming path, so
the child invocation stays byte-identical with and without streaming and the
final joined result is unchanged (buffering/timing only). Unlike the earlier
PYTHONUNBUFFERED=1 env injection that was removed, -u does not pollute the
child's os.environ and is not visible via os.getenv.
* Render only the selected main-content subtree in html_to_markdown
The main-content heuristic sized each <article>/<main> candidate
individually to pick the largest subtree, but then rendered every
matching tag in the document. A page with one real article plus
sibling related-post cards or comment threads passed the size gate on
the real article yet still emitted the unrelated siblings.
Size and render the same chosen subtree so only the selected
main-content subtree reaches the output.
* Studio: tighten chat-tool-streaming fix comments
* Studio: store tool-output-scope separators as unicode escapes
The pane-scope and tool-output-key separators were literal NUL (0x00) bytes, which made git treat the file as binary and hide its diff and blame. Write them as \u0000 escapes instead; the runtime key value is unchanged.
* Studio: bound tool-stream teardown when the client disconnects
stream_tool_execution ran its yield loop with no try/finally, so a gen.close() on client disconnect (GeneratorExit at a yield) skipped the worker join and never signalled cancellation. A tool that does not poll cancel_event mid-flight (web_search, MCP, search_knowledge_base) then kept request teardown blocked until the tool's own timeout. Thread the request cancel_event into the wrapper, set it only on the abnormal-exit path so a clean multi-tool turn is unaffected, and bound the worker join to a few seconds; the daemon worker cannot outlive the process.
* Studio: sandbox path remap no longer masks missing reads
The sandbox sitecustomize shim remapped code-interpreter prefixes (/mnt/data, /workspace, ...) onto the working directory for every open mode, including reads. A read of a path that truly did not exist was silently redirected onto a same-basename workdir file instead of raising on the path the model used, hiding real missing-input errors. Remap writes and creates as before, but remap a read only when the mapped workdir target already exists (re-reading a just-written artifact); otherwise keep the original absolute path so the failure stays truthful.
* Studio: bound web fetch with one overall deadline and cancellation
The web fetch applied timeouts per network operation, so a GitHub README API attempt plus its HTML fallback plus up to five redirect hops could run well past the tool timeout, and nothing aborted once the client had disconnected. Add a single wall-clock deadline shared across the API attempt, the fallback, every redirect hop and the body read, cap each hop's socket timeout at the time left on the budget, and poll cancel_event. SSRF host pinning, per-hop redirect revalidation, the five-hop cap and the size cap are unchanged.

for more information, see https://pre-commit.ci
* Studio: keep tool-stream teardown off the event loop on disconnect
The bounded worker join added for disconnect safety still ran on an abnormal close, so a client disconnect could wait the full join timeout; and the safetensors and Anthropic tool streams closed their generator synchronously on the event loop, unlike the GGUF path. On abnormal exit the daemon worker is abandoned, so join with a zero timeout instead of waiting; offload the safetensors and Anthropic gen.close to a thread to match GGUF; and surface a heartbeat as soon as cancel_event is set while the worker is silent so the route regains control at once instead of after a heartbeat interval.
* Studio: extend the web-fetch deadline to DNS, the body read, and search
The overall fetch deadline did not cover host resolution or the response body read, and query-mode web_search ignored cancellation. Resolve hosts (initial and every redirect) on a budget-polled helper so a slow or pre-cancelled getaddrinfo aborts on time; read the capped body in chunks with the budget re-checked between them so a slow-drip server cannot stretch a single read past the deadline; and gate the blocking DDGS query on cancel_event on both sides. SSRF host pinning, per-hop redirect revalidation, the five-hop cap and the size cap are unchanged.
* Studio: defer the sandbox remap notice and tighten os.open create flags
The one-shot remap notice fired while computing the mapping, so a read that kept its original path emitted a false notice and spent the notice a later genuine remap needed. Only emit it once _remap_open commits to the redirect. Separately, os.open classified O_TRUNC / O_APPEND without O_CREAT as creating, but those cannot create a missing file, so a missing target now stays truthful (only O_CREAT maps to the creating mode).

The GitHub README API returns the raw file, almost always Markdown. _looks_like_html classified a Markdown README opening with a block tag (<ul>, <ol>, <dl>, <pre>, <blockquote>) as HTML, so _fetch_page_text ran it through html_to_markdown and collapsed its headings, lists and fenced code into a single line. Sniff the README body with a stricter document-level check (doctype or a leading <html>/<head>/<body>) so only a real .html README is converted; the general page path is unchanged.

* Surface unclassified mid-stream Anthropic errors as SSE error events
The local Anthropic tool-stream and plain-stream paths called
_anthropic_stream_error_event(e) with force defaulting to False, so an
unclassified mid-stream failure (llama-server crash, decode OOM, a
dropped upstream socket) returned no event. The except block then fell
through to emitter.finish(), emitting a normal message_delta and
message_stop that masked a truncated turn as a clean finish.
Pass force = True at both fall-through sites so an unclassified failure
emits a 500 SSE error event and returns, matching the Anthropic
passthrough path that already forces it. Add regression tests covering
both stream paths.

* Studio: give each tool run a unique part id so finished cards keep their own output
Backend tool ids restart at call_0 every assistant response, and the
transient toolLiveOutput/toolFullOutput store maps were keyed by pane
scope plus that bare backend id. Two turns in the same pane therefore
shared one key: the stale-clear at tool_start only guards the forward
direction, so when a later call_0 finished and wrote its preserved full
output, every earlier still-mounted finished card reading the same key
re-rendered and displayed the newer tool's output instead of its own.
Mint one per-run-unique part id per backend id (call_0:<uuid>) and route
tool_start/output/args/end through a single resolver so all events for a
call resolve the same id. The durable part carries the unique id, so the
finished-card readers derive a collision-free key with no change, and the
awaiting-confirmation path keeps its own synthesized id. Outbound replay
stays paired (the assistant tool_call id and the role=tool result
tool_call_id both come from the part id) and gains unique ids across
turns, which strict providers require.

* Studio: add Voice settings tab (dictation, dictionary, read aloud)
New Voice tab in Settings, placed just before About:
- Dictation: microphone picker, browser STT engine, recognition language,
and an inline mic test with a live transcript
- Dictation dictionary: entries rewrite matching speech to their exact
spelling and casing, applied in both dictation paths
- Recent dictations: last 20 final transcripts with copy and clear, so
text can be recovered if it lands in the wrong place
- Read aloud: optional button on assistant responses with two engines,
curated system voices (novelty and legacy voices filtered, quality
ranked, capped at 20) or the TTS audio model loaded in Unsloth via
/audio/generate (e.g. Orpheus), plus speed, pitch, volume and preview
Settings persist in localStorage (unsloth_voice_settings) and are read
at call time so changes apply without reloading the runtime. Adds en
keys plus the tab label for ja, zh-CN and pt-BR.
* Studio: drop the single option STT engine select, rename TTS option
The STT engine dropdown only had one entry, so it added noise without
giving a real choice. The engine row can come back once local STT
models land. Also renames the TTS engine option Unsloth TTS model to
Load TTS model to make the action clearer.
* Studio: harden Voice settings against edge cases found in simulation
Simulated the feature across Chromium, Firefox and WebKit plus node
level unit runs and backend contract checks. Fixes from the findings:
- Dictionary rewrite used a replacement string, so entries containing
dollar patterns corrupted transcripts (A$$AP became A$AP, $& injected
the match). Switched to the callback form of String.replace
- Persisted voice settings now validate types on hydration: non string
micDeviceId, dictationLanguage and ttsVoiceURI, and non boolean
ttsEnabled fall back to defaults instead of flowing into the UI
- Dictionary entries are trimmed, capped at 120 chars and re-sanitized
on hydration
- The Test dictation panel now falls back to the default microphone
when the saved device is unplugged, matching the composer adapter
Test coverage: 46 unit assertions (dictionary regex edge cases across
unicode, word boundaries and injection, voice curation for simulated
macOS, Windows and Linux voice inventories, corrupt storage merge),
13 backend contract checks against /audio/generate on an isolated
instance, and 60 browser assertions across the three engines covering
rendering, degradation without SpeechRecognition, curation in a real
DOM, dictionary persistence with unicode and dollar entries, the
no-model preview error path and corrupt localStorage recovery.
* Studio: address Voice settings review feedback
Verified each review comment before acting. Confirmed and fixed:
- Editing a dictionary entry was broken in two ways: the store trimmed
on every keystroke so spaces could not be typed, and clearing the
field deleted the entry and unmounted the input mid edit. Updates now
keep the raw value and a blur commit trims or removes the entry
- The unplugged mic fallback checked instanceof DOMException, but a
cross browser probe showed Firefox and WebKit throw
OverconstrainedError objects that are not DOMExceptions, so the
fallback never fired there. Matching on the error name now
- When the browser ended a dictation test on its own (silence timeout),
the mic stream stayed open. All recognition end paths now stop the
tracks and save the transcript through a single finalize path
- The studio TTS audio element now releases its WAV data URL as soon as
playback ends, fails or is cancelled
- Allow microphone now reports insecure contexts (no mediaDevices)
accurately instead of claiming access was blocked
- Voice tab copy moved into i18n keys per src/i18n/AGENTS.md, so locale
overlays can translate it; en is the baseline and parity passes
- unsloth_voice_settings added to the Reset all local preferences key
list so voice preferences obey the reset
- Non default microphones note that the system default is used when the
browser speech engine cannot bind a specific device, since browsers
without the start(track) overload ignore the argument silently
Re-ran the full simulation set after the changes: 46 unit assertions,
13 backend contract checks and 60 browser assertions across Chromium,
Firefox and WebKit all pass, plus a dedicated browser probe for the
dictionary editing behavior.
* Studio: use the chat mic icon in Voice settings for consistency
The Voice tab and its buttons used the hugeicons Mic02 glyph while the
chat composer uses a custom filled mic. Extract that composer icon into
a shared lib/mic-icon component, drop the duplicate inline copies in
thread.tsx and shared-composer.tsx, and use it for the Voice tab icon
and the tab's mic buttons so the microphone looks the same everywhere.
* Studio: address second round of Voice settings review feedback
Verified each new comment against the current code first. One item was
already fixed in the previous round (recording transcripts when the
browser ends a dictation test on its own). Confirmed and fixed:
- The microphone row showed a picker with generic names when browsers
enumerate unlabeled devices before permission, leaving no way to
grant access from the row. It now branches on whether labels are
visible and shows Allow microphone otherwise
- Compare chat dictation ignored the selected microphone. It now opens
the chosen device with the same fallback rules as the main adapter,
passes the track to recognition where supported and releases the
stream when recognition ends
- Closing the Voice tab cancelled the shared speechSynthesis even when
read aloud was playing a chat message. Cleanup now only cancels when
the tab owns an active preview
- Double clicking Start test could race two recognizers and leak the
first stream. A starting flag set before the getUserMedia await makes
start reentrancy safe
- Turning off the read aloud setting mid playback removed the only stop
control. The stop button now renders whenever a message is speaking
- When an engine lacks the start(track) overload, both dictation paths
now release the selected device stream before retrying with the
default microphone instead of holding it open
- Read aloud support no longer requires Web Speech synthesis: the
Unsloth TTS engine only needs audio playback, so it stays available
in WebViews without speechSynthesis, with a clear error if the system
engine is chosen there
Not addressed here: cancelling in flight backend TTS generation on
stop. The route runs generation in a worker thread without a
cancellation path, which is shared pre existing behavior with audio
chat generation and belongs in a backend change.
All suites re-run green: 46 unit, 13 backend contract and 60 browser
matrix assertions across Chromium, Firefox and WebKit, plus probes for
the unlabeled device branch and the double click race.
* Studio: drop empty and duplicate voiceURIs so the Voice tab never renders a crashing Select item
* Studio: guard dictation mic lifecycle in Voice test and Compare composer
Release a microphone opened after the component unmounts, and stop Compare
dictation on a permission or security failure instead of silently recording
from the default device, matching the main chat adapter.
* Studio: fix dictation and read-aloud lifecycle edge cases in Voice settings
- Join final dictation chunks with a space so recorded transcripts do not merge words
- Ignore a stale recognizer onend so a quick stop then restart is not torn down
- Use previewingRef so a double click on TTS preview does not orphan the first request
- Keep the read-aloud stop control visible when a new run starts while a message is spoken
- Stop the dictionary remove button from deleting an adjacent entry on a blur then click race
* Studio: trim redundant Voice settings comments
* Studio: fix Voice preview and Compare dictation edge cases
- Only cancel the shared speechSynthesis for a system-voice preview, so stopping
a Studio preview no longer stops an unrelated chat read-aloud
- Release the Studio preview audio and its WAV data URL on normal completion
- Iterate every finalized result in Compare dictation so batched phrases are kept
- Cap persisted recent dictations to the last 20 on hydration
* Studio: use clipboard fallback for recents and release failed preview audio
- Copy recent dictations via the copyToClipboard helper so the execCommand
fallback works in Safari and insecure http LAN contexts
- Release the Studio preview audio when play() rejects, not just on ended/error
* Studio: surface dictation and read-aloud failures instead of failing silently
- Compare dictation reports microphone and speech-recognition errors via toast,
reusing the main chat adapter's describeMediaError and describeSpeechError
- Read-aloud toasts genuine model or synthesis failures while ignoring cancellations
* Harden cross-browser microphone errors
* Surface voice test recognition errors and fall back to Studio TTS
- Voice test now toasts non-abort speech-recognition failures instead of
ending silently, matching the main and Compare dictation paths.
- Read-aloud routes to the backend model when the runtime lacks Web Speech
synthesis (audio-only WebView), so it no longer errors immediately.
* Fix read-aloud fallback controls
* Guard read-aloud stop when deleting a non-speaking message
aui.message().stopSpeaking() throws unless this message is the one being
read aloud, so calling it unconditionally rejected the delete handler before
the message was removed. Only stop speech when this message is speaking.
* Cap recent dictation transcript length before persisting
Recent dictations only limited entry count, so a long transcript stored the
full text in the persisted voice settings and a few could exceed the
localStorage quota, throwing synchronously from the uncaught dictation cleanup
path. Truncate each entry on save and on hydration, matching the dictionary cap.
* Harden read-aloud stop on delete and surface preview playback errors
- Deleting a message now stops read-aloud when the spoken message is among
those removed (including a user prompt's cascaded assistant replies), read at
click time and guarded so a playback end between render and click cannot
abort the delete.
- Voice preview now reports playback failures instead of silently resetting
the button, matching the read-aloud path.
* Remove stray review notes; notify TTS subscribers; drop regex lookbehind
- Remove plans/review_*.md scratch files accidentally committed earlier.
- Studio read-aloud now notifies speech subscribers on the async
starting -> running transition so status does not stay stuck at starting.
- Dictionary correction captures the leading boundary instead of a lookbehind
so it works on engines with dictation but no lookbehind (Safari < 16.4).
* Fix keyboard deletion of an emptied dictionary entry
Tabbing to a just-emptied row's Remove button blurred the input and
commit-spliced the empty row, so with index-keyed rows the button's keyboard
activation deleted the next entry. Skip the commit when focus moves to that
row's Remove button; the existing mouse guard is kept.
* Reapply Studio TTS playback rate on loadedmetadata
Some browsers reset an Audio element's playbackRate to 1 once the source
loads, so the selected speed could be dropped for read-aloud and voice
preview. Reapply it on loadedmetadata in both paths.

* Studio: permission levels for chat tool calls (Ask, Approve for me, Off, Full access)
Replace the Bypass permissions on/off toggle with a four level permission
selector, available in Settings > General (new Permissions section above
Notifications), the chat settings panel, the composer plus menu, and a new
always visible composer pill.
Levels:
- Ask for approval: every local tool call pauses for allow/deny.
- Approve for me: only calls detected as potentially unsafe pause; the
python/terminal sandbox stays on.
- Off: never pauses; sandbox stays on (previous default behavior).
- Full access: never pauses and the sandbox is disabled. Still requires
the danger confirmation and is never restored across reloads.
Backend adds permission_mode to the OpenAI compatible and Anthropic
passthrough payloads and threads it through both tool loops. Auto mode
uses a fail closed classifier in tools.py: terminal commands must be on
a read only allowlist with no redirection or substitution, python code
is AST scanned for writes, exec, process and network use, MCP tools
auto run only with read only style names. Unknown tools always ask.
Legacy bypass_permissions and confirm_tool_calls keep their exact
behavior for existing API callers.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio permissions: Off is a plain toggle below Full access
Off moves to the bottom of the level menu with a short description and
acts as the feature-off state: the composer pill is hidden entirely
while Off, and reselecting the active level toggles back to Off.
* Studio permissions: higher contrast composer pill text
The permission pill uses a foreground based grey instead of the shared
muted pill color, so it reads darker in light mode and lighter in dark
mode. Full access keeps the danger yellow.
* Studio permissions: panel dropdown layout and shorter tooltip
Chat settings panel: the Bypass permissions label sits on one line with
a full width dropdown underneath, styled like the other panel selects.
Tooltip shortened and wording uses Unsloth instead of Studio.
* Studio permissions: harden auto-mode unsafe detection
Extend the Approve for me classifier to catch write and exec paths that
slipped through:
- terminal: sort -o, tree -o, xxd -r, find -exec/-execdir/-ok/-delete
and find -fprint/-fprintf/-fls now ask; plain read-only forms still
auto-run. awk is no longer allowlisted since its program can write and
call system().
- python: from-imports of mutating names (from os import remove [as rm])
and star imports now ask.
Found by a fuzz and edge-case simulation matrix; pinned in
test_permission_mode.py.
* Studio permissions: split multi-line terminal commands in auto detection
A shell runs each line as its own command, but shlex reads newlines as
whitespace, so "ls\nrm -rf x" demoted rm to argument position and
auto-ran. Normalize newlines and CR to separators, and treat any all
separator token as a command boundary so runs of blank lines still
split. Found by the simulation matrix; pinned in tests.
* Studio permissions: address review feedback on auto-mode detection
Auto-mode (Approve for me) safety classifier hardening:
- Python: flag any reference to a mutating attribute, not only direct
calls, so indirect refs (f = os.remove; f(x)) and aliases ask. Detect
Path.open(mode) write modes and wrap the AST walk to fail closed.
- Terminal: match attached short output flags (sort -o/tmp/out) and keep
find context across grouping parens so find ( -delete ) asks.
- Both: ask before reads that escape the sandbox workdir via parent
traversal or hit credential paths (.ssh, .aws, id_rsa, .pem, etc.).
permission_mode plumbing:
- Fold permission_mode=full into bypass_permissions at the request model
so route-level confirm-gate guards see it as bypass.
- Reject ask/auto on the Anthropic Messages server-tools path, which has
no confirmation channel (mirrors the confirm_tool_calls rejection).
- Keep forced RAG autoinject in auto mode: the safe search_knowledge_base
retrieval never gates, so derive the skip from the real confirm need.
- Reset all local preferences now also clears the legacy confirm key so a
reset restores the fresh default instead of the old level.
Regression tests added for each case.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio permissions: close auto-mode classifier gaps from review round 2
Auto mode ("Approve for me") let a few mutating calls through as safe:
- os.open(...) always creates/writes a descriptor, so treat it as unsafe
even though builtin open in read mode stays safe.
- fd -x/--exec/-X/--exec-batch runs a command per match; scan for these
alongside find's -exec/-delete.
- tempfile writes artefacts and hands back writable handles, so importing
it now asks.
- Calling the result of a call (getattr(os, "remove")("x"), partials) is a
dynamic target the AST can't vet, so fail closed.
- An MCP tool whose name pairs a read verb with a mutating one
(get_or_create_issue, read_and_delete_file) no longer auto-runs on the
read prefix alone.
Also fold permission_mode="off" into confirm_tool_calls=False on both
request models so the non-stream route guard sees the disabled gate, and
drive the Confirm tool calls toggle off permission_mode="ask" so auto no
longer shows it on.
* Harden auto-mode classifier and normalize bypass to full for PR #7079
Approve for me now asks for a few cases it previously auto-ran:
- os.open via an os alias (import os as o; o.open(path, O_CREAT))
- pathlib symlink_to / hardlink_to / link_to
- importlib.import_module dynamic imports
- os.mkfifo / os.mknod / os.utime
Also fold bypass_permissions into full when a stale ask/auto permission_mode
is sent alongside it, so the Anthropic route guard no longer 400s those legacy
callers. Adds classifier and request-model regression tests.
* Close more auto-mode classifier gaps for PR #7079
Approve for me now asks for cases the review surfaced:
- builtin open aliased to a name (f = open; from builtins import open as w)
or looked up dynamically (globals()['open'])
- pickle / marshal / shelve / dill deserialization
- io.FileIO write handles
- sort --compress-program (runs an external program)
- MCP names carrying save/archive/submit/commit/push/sync/register verbs
Also refine the attribute open() write check so an explicit read mode
(ZipFile.open(name, "r")) stays auto while os.open flags still ask. Adds
test coverage for each case.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Close three more auto-mode gaps for PR #7079
- rg runs an arbitrary program per file via --pre / --hostname-bin, so
"Approve for me" now asks for those flags (rg is on the read-only
allowlist).
- A path-qualified command token (./ls, /tmp/cat) is an arbitrary
executable, not the trusted utility its basename matches, so it asks
before running.
- A direct /chat/completions caller that sets permission_mode ask/auto
but omits the legacy confirm_tool_calls flag now self-enables the
confirmation gate, so tools can no longer run ungated on that path.
Adds classifier and request-model tests for each case.
* Close auto-mode classifier gaps from review round 3 for PR #7079
Approve for me now asks for cases the latest pass surfaced:
- short-option clusters bundling a write flag (sort -uo out => -u -o)
- procfs reads that leak a process env/args/memory
(cat /proc/self/environ, /proc/PID/cmdline, maps)
- env-assignment prefixes that change command lookup/loading
(LD_PRELOAD=x ls, PATH=. ls, IFS=x ls); benign FOO=1 cmd stays auto
- os.open imported as a bare callable (from os import open as o)
Also drops ps from the safe terminal allowlist: its BSD environment
flags (ps auxe, ps eww) dump a parent process's unscrubbed env and
cannot be flag-parsed reliably, so ps always asks now. Adds classifier
tests for each case.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Close auto-mode classifier gaps from review round 4 for PR #7079
Terminal (Approve for me now asks for these):
- cd dropped from the safe allowlist: cd /; cat etc/passwd moves the
shell out of the session workdir so a later relative read escapes it
- env -C/--chdir (workdir escape) and -S/--split-string (builds a fresh
command line); wrapper flags are now checked
- /etc//passwd and /etc/./passwd normalize to /etc/passwd before the
sensitive-path scan
- a sensitive path split across an assignment and an argument
(p=/etc; cat $p/passwd) via best-effort NAME=value expansion
Python:
- builtins.exec / builtins.eval attribute calls (dynamic code execution)
- destructured open aliases (f, _ = (open, print); f('out', 'w'))
- a sensitive path composed from literals (os.path.join('/etc','passwd'),
'/etc' + '/passwd')
- ZipFile/TarFile write modes (ZipFile(name, 'w')); the reader stays auto
Adds classifier tests for each case.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Close auto-mode classifier gaps from review round 5 for PR #7079
Terminal (Approve for me now asks for these):
- procfs reads hidden by shell quotes (cat /proc/$PPID/enviro''n) or
quoted/nested-variable assignments (p="/proc/$PPID"; cat $p/environ):
quotes are stripped and NAME=value prefixes expanded before the scan
- LESSOPEN/LESSCLOSE, which make less run an input preprocessor command
Python:
- os.chdir / os.fchdir, which move the cwd so a later relative read
escapes the sandbox workdir
- sensitive paths composed via a pathlib / chain (Path('/etc') / 'passwd')
or an f-string of literals (f'/proc/{pid}/environ')
- runpy (import) and runpy.run_path / run_module, which run arbitrary code
Adds classifier tests for each case.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Close auto-mode classifier gaps from review round 6 for PR #7079
Approve for me now asks for these:
- a mutating callable reached through a getattr alias
(rm = getattr(os, "remove"); rm("f")): calls through a getattr-bound
name fail closed
- compound MCP tool names carrying clone/checkout/comment/fork/tag/
invite/share, which start with a read verb but still mutate
- a sensitive path hidden behind a glob (cat /e??/passwd,
cat /e[t]c/passwd): a ? / * / [..] token is matched against the
sensitive-file set and bracket classes are de-obfuscated; benign
globs (ls *.py) stay auto
Also run first-pass RAG retrieval in off mode: like auto, off never
prompts, so a direct caller passing a stale confirm flag should not lose
document retrieval (both tool loops).
Adds classifier tests for each case.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Close auto-mode classifier gaps from review round 7 for PR #7079
Approve for me now asks for these:
- __builtins__.exec / __builtins__.eval (dynamic code via the dunder)
- terminal reads that hide a credential path behind a backslash escape
(cat /et\c/passwd)
- read-named MCP filesystem calls pointed at a credential path
(mcp__fs__read_file {"path": "/etc/passwd"})
- compound MCP names carrying append / prepend
- open aliased through a subscript or builtins attribute
(f = globals()["open"]; f = builtins.open) then called to write
- open(..., **{"mode": "w"}) where a kwargs splat hides the write mode
- a sensitive path with a dynamic segment (open(f"/etc/{name}"),
os.path.join("/etc", name)); /tmp/{name} stays auto
- urllib3 networking
Also stop folding permission_mode ask/auto into confirm_tool_calls for
external-provider requests: that branch rejects confirm_tool_calls with
tools, and the mode only governs local tool calls. Local requests still
self-gate. Adds tests for each case.
* Close auto-mode classifier gaps from review round 8 for PR #7079
Approve for me now asks for these:
- dbm on the unsafe-module list: dbm.open(file, "c"/"n") creates files,
and importing the family signals a persistence writer
- reads of ~/.azure and ~/.config/gh credential stores (Azure/GitHub
tokens), in terminal, MCP arguments, and Python literals
- compound MCP names carrying upsert / assign
Adds classifier tests for each case.
* Gate secret mounts and fix the composer pill count for PR #7079
- Add Docker/Kubernetes secret mount dirs (/run/secrets,
/var/run/secrets) to the sensitive-path checks, so Approve for me asks
before reading injected credentials (terminal, MCP args, Python).
- Count the always-visible permission pill in the composer's compact
threshold so labels collapse at the intended width instead of
overflowing by one pill.
Adds classifier tests for the secret mount paths.
* Close auto-mode classifier gaps from review round 10 for PR #7079
Approve for me now asks for these:
- qualified pathlib constructors (pathlib.Path('/etc') / name), folded
the same as bare Path(...), so a dynamic sensitive path is detected
- open aliased through an annotated assignment (f: object = open;
f('out', 'w')), tracked like a plain assignment
- recursive searches rooted at an absolute path (grep -R TOKEN /home,
rg TOKEN /, fd pattern /etc), which read host files outside the
sandbox tree; sandbox-relative searches stay auto
Adds classifier tests for each case.

* Close auto-mode classifier gaps from review round 11 for PR #7079
Approve for me now asks for these terminal reads, which bash would
expand into a sensitive path only after the classifier had approved:
- a glob that resolves into a secret mount or credential dir
(cat /r?n/secrets/hf_token, cat /root/.s??/id_rsa)
- a recursive search rooted at a tilde home (grep -R TOKEN ~root,
grep -R TOKEN ~/logs)
- a brace expansion that builds a credential path (cat /etc/pass{w,}d)
- a default/alternate parameter expansion that builds one
(cat /etc/pass${x:-wd})
- an input redirection that hides a glob (cat </e??/passwd)
And these python calls:
- a str.format-built sensitive path (open('/etc/{}'.format('passwd')))
- writer methods that persist to disk without open() (numpy.save,
Image.save, plt.savefig, DataFrame.to_csv, json.dump)
Segment-wise directory matching keeps benign globs (ls /home/*/projects)
auto. Adds regression tests for each case and its safe counterpart.
* Close auto-mode classifier gaps from review round 12 for PR #7079
Approve for me now asks for these too:
- a terminal read whose parent traversal hides behind a redirection with
no following space (cat <../../notes)
- a python read whose path is built with str.join
(open(''.join(['/etc', '/passwd']))), told apart from os.path.join
- a dynamic-code builtin reached through an alias
(from builtins import eval as e; e(...); x = builtins.exec; x(...))
Adds regression tests for each case and its safe counterpart.
* Close auto-mode classifier gaps from review round 13 for PR #7079
Approve for me now asks for these too:
- a recursive search whose root is hidden behind an assignment
(p=/; grep -R TOKEN $p): the recursive-root test now runs on the
assignment-expanded tokens as well
- a python read whose sensitive path is split through a literal variable
(base = '/etc'; open(base + '/passwd')), including via an f-string
- numpy ndarray.tofile, which persists without open()
- a sequence brace read (cat /etc/pass{w..w}d), expanded alongside the
comma brace form before the sensitive-path scan

- a pathlib object reused through a name (p = Path('/etc'); p / 'passwd')
- old-style percent formatting ('%s/%s' % ('/etc', 'passwd'))
- Path.joinpath ('/etc'.joinpath('passwd'))
- a bytes path literal (open(b'/etc/passwd'))
And these terminal reads, which bash expands into a sensitive path only
after the classifier had approved:
- a substring parameter expansion off an assignment
(p=passwd; cat /etc/${p:0:6})
- an ANSI-C quoted path (cat $'/etc/pass\x77d')
- a glob into an Azure or GitHub CLI config dir
(cat /home/*/.az?re/..., cat /home/*/.config/g?/...)

database file (and runs DDL/DML) with no open()/writer attribute for
the AST checks to catch, so treat the module like dbm and ask.
- Only self-enable confirm_tool_calls for Studio's own tool loop. The
ask/auto fold previously set confirm on every non-provider request,
including a plain client-tool passthrough (client-supplied tools that
Studio does not execute), which then tripped the local-tool
streaming-confirm route guard and rejected the passthrough. Restrict
the fold to requests that actually ask Studio to run tools
(enable_tools / enabled_tools / mcp_enabled).
Adds regression tests for the sqlite3 write and for the passthrough vs
tool-loop confirm behavior.

* Close auto-mode gaps from review round 18 for PR #7079
Classifier (auto mode asks for these):
- os.open through a module alias (import os as o; o.open(...)); os/posix
aliases are tracked like the literal module name.
- less/more pagers, whose escapes (+cmd, !shell, -o/--log-file, LESSOPEN)
can run a command or write a file the command-name allowlist cannot
see, so they are no longer auto-approved.
- a read-named MCP tool carrying a mutating query
(query_database {"query": "DELETE FROM runs"}); DML/DDL statements are
matched as whole statements so a natural-language query that merely
contains "delete" stays safe.
- ML persistence helpers (save_pretrained / save_file / save_model /
save_weights / save_lora / save_checkpoint) that export weights to disk.
Route:
- Honor CLI-forced tools when deriving the confirm gate. When a process
policy (unsloth run --enable-tools) opens the local tool loop without a
request-level tool signal, a permission_mode ask/auto request now
derives confirm at the route (GGUF and safetensors paths) so the mode
still gates the call, and a non-streaming ask/auto request is rejected
rather than running unprompted. A plain client-tool passthrough (no
local loop) is unaffected.
Adds regression tests for each case and its safe counterpart.

* Close auto-mode classifier gaps from review round 19 for PR #7079
Approve for me now asks for these too:
- a terminal read whose path is built by indirect parameter expansion
(x=passwd; p=x; cat /etc/${!p})
- a bash /dev/tcp or /dev/udp redirection, which opens a network socket
(cat </dev/tcp/host/port)
- a python read via pathlib's receiver-plus-pattern glob
(Path('/etc').glob('passw?'))
- a python read whose sensitive root passes through a normalizer
(os.path.abspath('/etc'), Path('/etc').resolve())
- a pickle-backed loader that can execute code on load
(torch.load, joblib.load, pandas.read_pickle), tracked through module
import aliases
- compiled code wrapped into a callable (compile(...) + types.FunctionType)
Adds regression tests for each case and its safe counterpart.
* Honor unset permission_mode as ask across the local tool loop for PR #7079
Three gaps where an omitted permission_mode did not behave as the
documented default ("ask"):
- The frontend only sent permission_mode / confirm_tool_calls /
bypass_permissions when a tool pill was on. A process policy
(unsloth run --enable-tools) can open the tool loop with no pill, so
the backend never saw the selected gate. Send the three permission
fields at the top level of every local chat payload instead.
- The backend read payload.confirm_tool_calls directly at the
pre-switch guard and both late per-backend derivations, so an unset
mode fell through as no-gate even for an explicit ask/auto. Add
_permission_mode_confirm(payload): explicit confirm_tool_calls wins,
explicit ask/auto engage the gate, off/full never prompt, and an
unset mode defaults to ask only where realizable (streaming), keeping
the legacy no-gate run for non-streaming unset requests.
- A forced ask/auto tool loop (CLI --enable-tools) with no stream now
400s at the pre-switch guard before evicting the resident model,
matching the existing confirm-without-stream rejection.
Adds test_permission_mode_confirm_derivation covering the derivation
truth table.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Declare permission_mode and bypass_permissions on the local chat request type
The previous change moved permission_mode, confirm_tool_calls and
bypass_permissions to the top level of the local chat payload. They had
lived inside a conditional spread, which is not subject to excess
property checking, so the fields were never declared on
OpenAIChatCompletionsRequest. At the top level tsc flagged
permission_mode as unknown (TS2322), failing the frontend build and
every job whose Studio install builds the frontend.
Add permission_mode and bypass_permissions to the request interface
(confirm_tool_calls was already present).
* Close auto-mode classifier gaps from review round 21 for PR #7079
Auto mode ("Approve for me") now asks for these too:
- a pathlib read built from a concrete constructor (PosixPath, WindowsPath
and their Pure* forms), which the folder previously ignored so
PosixPath('/etc') / 'passwd' lost its /etc root and ran unprompted
- a terminal or python read of the ssh host keys under /etc/ssh, which
the sensitive-path regex only covered for passwd/shadow/sudoers
- a read whose path variable is reassigned: the whole-tree pre-scan kept
the last binding, so base = '/etc'; open(base + '/passwd'); base = 'data'
folded to data/passwd and ran even though execution reads /etc/passwd;
any multiply-bound name now folds to the escape sentinel and asks
Also stop the pre-switch guard from rejecting a plain client-tool
passthrough. permission_mode only implies the confirm gate for Studio's
own local tool loop (enable_tools / enabled_tools / mcp_enabled); a
non-streaming client-tool passthrough that carries permission_mode
ask/auto (confirm_tool_calls left unset by the validator) must forward to
the provider branch. Only an explicit confirm_tool_calls=True still forces
the local-confirm rejection there.
Adds regression tests for each case and its safe counterpart.
* Fix permission-pill compaction count and Full-access confirm sync for PR #7079
Two frontend consistency issues in the permission-level UI:
- The composer collapses tool pills to icons above four, but the count
left out the permission pill, which renders in every mode except off.
With one optional pill also shown the row reached five pills without
collapsing and could overflow. Count the pill when it is visible
(permission_mode != off).
- Entering Full access via setPermissionMode('full') or
setBypassPermissions(true) left confirmToolCalls at its previous value,
so a Full-access run (which sends confirm_tool_calls=false) could still
report confirmations as enabled in response metadata. Set
confirmToolCalls false at both entry points.
* Close auto-mode classifier gaps from review round 23 for PR #7079
Auto mode ("Approve for me") now asks for these too:
- a command using an abbreviated GNU long option that reaches a
write/exec action (sort --out= for --output, env --ch= for --chdir,
fd --base-dir= for --base-directory); a prefix of an unsafe long flag
now fails closed
- printf -v NAME, which assigns to a shell variable, so
printf -v PATH %s .; ls can rewrite PATH and run ./ls unprompted
- fd --base-directory / --search-path, which move the search root
outside the session workdir without any positional slash token
- an MCP tool whose compound read name carries a copy-style mutator
(read_and_copy_file, get_and_snapshot_volume): copy, duplicate,
import, export, download, backup, restore, snapshot, mirror
Also treat an omitted permission_mode as its documented default ("ask")
on the Anthropic Messages server-tool path. That branch has no
confirmation channel and already rejects explicit ask/auto, so an
omitted mode now falls into the same rejection instead of silently
running server tools unprompted, unless the caller opted out with
confirm_tool_calls=false (the legacy equivalent of "off"). off/full and
that opt-out still run; the two routing tests that relied on the old
implicit run now set permission_mode="off".
Adds regression tests for each case and its safe counterpart.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Refine permission gating from review round 24 for PR #7079
Four fixes from the latest review:
- Anthropic Messages server tools: an omitted permission_mode no longer
rejects a request that only runs safe server tools (web_search), so
existing Anthropic callers keep working. It still rejects an omitted
mode when a local tool (terminal/python) is selected, and an explicit
ask/auto is still rejected outright. off/full and a
confirm_tool_calls=false opt-out always run.
- Pre-switch confirm-without-stream guard: use
_explicit_studio_tool_loop_requested (the same predicate the
passthrough router uses) instead of the policy-inclusive
_effective_enable_tools, so a process --enable-tools policy no longer
turns a client-tool passthrough into a local-loop rejection.
- Auto mode now asks for `uniq INPUT OUTPUT`: uniq writes its second
file positional, so a second positional (numeric flag values skipped)
is treated like `sort -o`. A lone `uniq file` or piped `... | uniq`
stays safe.
- MCP mutation check now strips SQL comments before matching, so
DELETE/**/FROM and UPDATE/**/users (comment-as-whitespace) no longer
slip past the DML/DDL denylist.
Adds regression tests for each case and its safe counterpart.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Close auto-mode gaps from review round 25 for PR #7079
Auto mode ("Approve for me") now asks for these Python cases too:
- a bare archive constructor with a write mode (from zipfile import
ZipFile; ZipFile('out.zip', 'w')), tracked through import aliases like
the zipfile.ZipFile attribute call already was
- a dynamic lookup aliased through getattr (g = getattr;
rm = g(os, 'remove'); rm('file')), not just direct getattr(...) calls
- a callable that wraps open or a writer via functools.partial
(w = partial(open, mode='w'); w('out.txt')), which hides the write mode
Also:
- Always-safe tools (render_html) stream their early provisional canvas
card in auto mode again. The provisional-card guard mirrored the raw
confirm flag, which suppressed the early card under Approve-for-me; it
now reuses the auto-mode safety decision (is_always_safe_tool).
- The assistant-ui composer no longer counts the permission pill toward
its collapse threshold when the level is Off (the pill renders null
there), matching the other composer.
Adds regression tests for each case and its safe counterpart.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Align permission-mode confirm guards with the router (review round 26)
Three pre-switch confirm-gate checks disagreed with how the tool
loop actually enters, so a valid request could 400 (or an invalid
one could evict the resident model) at the wrong point:
- The /chat/completions pre-switch guard only looked at explicit
request fields, so a process --enable-tools policy that forces the
loop on (request omits enable_tools, no client tools) slipped past
it and only 400ed after _maybe_auto_switch_model had swapped the
model. It now mirrors the router's own loop-entry gate
(_effective_enable_tools or mcp, tool_choice="none" disabling it
unless explicitly asked) while still deferring to client-tool
passthrough, so the policy-forced case is caught before the switch.
- The ChatCompletionRequest full/off fold treated enabled_tools by
itself as a local-loop request and set confirm_tool_calls=True.
The router never starts the loop on enabled_tools alone (it only
filters which tools run), so a non-streaming passthrough carrying
client tools plus enabled_tools 400ed instead of routing verbatim.
The fold now keys off the same enable_tools / mcp_enabled signals.
- The Anthropic /v1/messages unsupported-mode rejection (ask/auto,
or an omitted mode selecting terminal/python) ran inside the
post-switch server-tools block, so an invalid request evicted the
resident model before the 400. It now runs before the auto-switch,
determined from the requested server tools, like the neighboring
malformed- and mixed-tool guards.
Adds regressions for each: a policy-forced non-streaming ask/auto
guard rejection that never reaches the switch, an enabled_tools-only
passthrough that keeps confirm unset, and an Anthropic rejection that
precedes _maybe_auto_switch_model.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Close auto-mode classifier gaps from review round 27 for PR #7079
Auto mode ("Approve for me") now asks for these host-mutating or
host-reading cases it previously ran unprompted (the sandbox does not
jail filesystem reads, and terminal commands can change host state):
- Destructured string literals fold into the scanned path now, so
base, leaf = ('/etc', 'passwd'); open(base + '/' + leaf).read()
resolves to /etc/passwd and asks, like the single-assignment form
already did. The tuple/list unpacking branch tracked only aliases to
open; it now also binds literal and folded-path elements.
- pathlib name rewrites fold to the rewritten path:
Path('/etc/x').with_name('passwd').read_text() (and with_stem /
with_suffix) spell no literal /etc/passwd but resolve to it, so they
are folded and caught. Benign in-sandbox rewrites stay safe.
- hostname NAME (or -F/--file, -b/--boot) sets the hostname, so a
positional or a set flag asks; bare hostname and the display flags
(-f/-i/-I/...) stay read-only.
- date -s/--set STRING and the bare MMDDhhmm... positional set the
system clock and now ask; the display forms stay read-only (+FORMAT,
-u/-R, and -d/-r/-f whose following value is skipped so date -d
tomorrow is not mistaken for a clock-setting positional).
Adds regression rows for each gap and its safe counterpart.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Close more auto-mode classifier gaps from review round 28 for PR #7079
Auto mode ("Approve for me") now asks for these cases too:
- Mapping-style %-formatted paths. '/etc/%(f)s' % {'f': 'passwd'} folds
to /etc/passwd and asks; a dynamic value or a non-literal mapping
leaves the NUL marker so /etc/<dynamic> still fails closed. The path
folder previously handled only tuple/scalar % right-hand sides and
returned None for a dict, hiding the sensitive segment.
- A read-named MCP database tool carrying PostgreSQL COPY. COPY ... FROM
bulk-loads a table and COPY ... TO writes a server-side file, so both
are matched as mutating queries like DELETE/UPDATE already were. A
'copy' substring in a column name stays safe (word boundary).
- logging file handlers. logging.FileHandler('out.log', mode='w') (and
the default append mode, RotatingFileHandler/TimedRotatingFileHandler/
WatchedFileHandler, and the bare from-import form) create or truncate
a file like open(..., 'w'), so they are classified as writer calls.
StreamHandler / NullHandler and logging reads stay safe.
Adds regression rows for each gap and its safe counterpart.
* Fix writer aliases, GraphQL mutations, and auto server tools (review round 29)
- Auto-mode Python: an aliased writer or archive constructor is tracked
like the existing open alias, so from numpy import save; s = save;
s('out.npy', arr) (and z = ZipFile; z('a.zip', 'w'), incl. the
destructured forms) ask instead of running the write unprompted. A
benign builtin alias (x = len) stays safe.
- Auto-mode MCP: a read-named tool carrying a GraphQL mutation now asks.
query_graphql {"query": "mutation { deleteIssue(id: 1) }"} matches a
leading mutation keyword (GraphQL uses # comments, so it scans the raw
payload); GraphQL read queries stay safe.
- Anthropic /v1/messages: permission_mode "auto" no longer 400s a
safe-only server-tool selection. auto only needs a confirmation
channel for an unsafe call, so like the omitted default it runs for
web_search / RAG / render and rejects only when a gate-needing local
terminal/python tool is selected. ask still always rejects (it asks
per call, which this passthrough cannot honor). The rejection stays
ahead of the model auto-switch.
Adds regression rows/cases for each.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Gate asyncio spawn, net clients, default-captured open; allow safe-only auto (round 30)
Auto-mode Python now asks for more process/network/write vectors:
- asyncio process spawners (asyncio.create_subprocess_exec/shell and a
loop's subprocess_exec/shell) run an arbitrary program without the
terminal blocklist, so they gate like os.system/subprocess.
- stdlib network clients imaplib / poplib / nntplib / xmlrpc(.client) /
webbrowser open outbound connections the sandbox does not namespace
off, so their import asks like the other network modules.
- a callable captured as a function or lambda parameter default
(def f(o=open): o('out', 'w')) now binds that parameter into the same
alias set, so the later write through it is gated. A benign default
(o=len) stays safe.
Also, permission_mode "auto" no longer 400s a non-streaming local tool
request whose selection is always-safe-only (web_search / RAG / render).
auto only prompts for a classifier-flagged call, so a safe-only auto
request needs no stream, while ask, an explicit confirm_tool_calls=true,
MCP, and an unrestricted or unsafe selection still require it. Applied
via a shared _confirm_gate_needs_stream helper at the pre-switch, GGUF,
and safetensors confirm-stream guards; the loop's per-call confirm flag
is unchanged.
Adds regression rows/cases for each.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Catch brace-glob paths and attribute writer aliases; unfold auto (round 31)
- Terminal auto mode now runs the glob-sensitive scan over every
expansion candidate, so a brace-expanded glob (cat /e{t,}c/pass?d,
which bash expands to /etc/pass?d and then globs to /etc/passwd) asks.
Brace expansion alone spells no literal /etc/passwd and the glob only
resolves once the brace group is expanded, so scanning both together
is required. A benign brace + glob stays safe.
- Python auto mode now tracks a mutating attribute captured as a plain
name: s = np.save; s('out.npy', arr) binds a writer alias, a captured
.open bound method (p = Path('out').open; p('w')) fails closed on any
call since its mode position varies, and z = zipfile.ZipFile is gated
like the bare import. A benign attribute alias (x = np.mean) stays safe.
- permission_mode "auto" is no longer folded to confirm_tool_calls=true
on the request model. Folding it defeated the safe-only-selection
exception in _confirm_gate_needs_stream (an explicit confirm forces
stream=true), so a non-streaming safe-only auto request was rejected.
Leaving it unset lets the route apply the exception; the mode still
drives the loop's per-call gate. "ask" still folds (it gates every
call).
Adds regression rows/cases for each.
* Harden SQL/GraphQL/writer classification and passthrough guards (round 32)
MCP argument mutation detection (read-named query tools):
- CREATE DDL now matches modifiers and the broader object set, so
CREATE OR REPLACE VIEW, CREATE UNIQUE INDEX, CREATE TEMP TABLE,
CREATE MATERIALIZED VIEW and CREATE FUNCTION ask.
- Stored-procedure invocation (CALL proc(...), EXEC/EXECUTE) and VACUUM
ask; a natural-language "call me back" stays safe via the trailing
"(" / ";" / end lookahead.
- GraphQL # comments are stripped before the mutation match, so
mutation # note\n { deleteIssue(id: 1) } no longer hides the mutation.
Python auto-mode classification:
- numpy.memmap / open_memmap and pandas ExcelWriter / HDFStore create or
truncate a file on construction, so they gate like open(..., "w").
- asyncio networking (asyncio.open_connection, loop.create_connection /
create_server and unix variants) opens outbound connections/listeners
the sandbox does not isolate, so it gates like socket.connect.
Terminal auto-mode: file -C / --compile writes a compiled magic database.
Routing:
- A JSON-schema response_format is guided-decoding passthrough, not a
local tool loop, so a --enable-tools policy no longer 400s a
non-streaming ask/auto structured-output request at the confirm guard.
- An explicit confirm_tool_calls=False opts out of the Anthropic Messages
server-tool gate entirely (it wins over the mode, mirroring
_permission_mode_confirm and the GGUF path), so it runs even under ask.
Adds regression rows/cases for each.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Track path-ctor aliases, exempt empty selection and safe safetensors card (round 33)
- Python auto mode now propagates path constructor / join aliases, so
assigning Path or os.path.join to another local name is still folded:
P = Path; (P('/etc') / 'passwd').read_text() and j = os.path.join;
open(j('/etc', 'passwd')) ask, while a benign /tmp alias stays safe.
- _confirm_gate_needs_stream now distinguishes an omitted enabled_tools
(None, all tools) from an explicit empty list ([], no tools). An empty
selection runs no built-in tool and cannot prompt, so a non-streaming
auto request with enable_tools=true, enabled_tools=[] is no longer
400ed under a --enable-tools policy.
- The safetensors provisional render_html card now uses permission_mode:
render_html is always safe and never prompts, so its early canvas card
streams under auto (which ships confirm_tool_calls=true) instead of
being suppressed, matching the GGUF path's is_always_safe_tool exemption.
Adds regression rows/cases for each.

* Extend auto-mode classifier: SQLite mutations, more net/xattr/compressed writers
Additional fail-closed gaps found by a fresh adversarial pass, each with a
reproduction and a benign control:
- MCP read-named tools now ask on SQLite-flavored writes the base DML/DDL regex
missed: ATTACH / DETACH DATABASE, a write-form PRAGMA (PRAGMA journal_mode=WAL
/ user_version=42 / foreign_keys(0), while the read-form PRAGMA journal_mode
stays safe), and load_extension() which loads and runs an arbitrary shared
library.
- Python auto mode now gates the remaining asyncio network entry points
(start_server, open_unix_connection, loop.create_datagram_endpoint,
sock_connect), os.setxattr / os.removexattr metadata writes, the gzip / bz2 /
lzma single-stream writers (GzipFile / BZ2File / LZMAFile, mode-gated like
ZipFile so a read stays safe), pandas to_xml, and the websockets client.
Benign controls (SELECT 1, read-form PRAGMA, asyncio.sleep, gzip read, numpy
read, natural-language "attach"/"analyze") stay safe. Regression rows added to
test_permission_mode.py.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Close follow-up auto-mode gaps: SQLite/GraphQL variants, more writers and net
A fresh adversarial pass on the previous round found consistent extensions of
the same fail-closed rules, each reproduced with a benign control:
- MCP read-named tools: DROP / ALTER now cover the same broad object set as
CREATE (DROP FUNCTION, ALTER INDEX, DROP MATERIALIZED VIEW); ATTACH is caught
without the optional DATABASE keyword via its quoted-path form; a
schema-qualified write PRAGMA (PRAGMA main.user_version=1) is matched; and a
GraphQL mutation carrying directives (mutation M @audit { ... }) is treated as
a mutation.
- Python auto mode: os.startfile (Windows program launch), asyncio
start_unix_server, and the socketserver framework now ask; a gzip/bz2/lzma
open imported under an alias (from gzip import open as gopen) is gated like
builtin open; and a dynamic path prefix that can form a sensitive absolute
root (open(chr(47) + "etc/passwd"), open(os.sep + "etc/passwd")) is treated as
sensitive, while a dynamic prefix with a benign suffix stays safe.
Benign controls (read-form PRAGMA, natural-language "attach ... as", "drop the
idea", SELECT dropped_at, query @cached, gzip read alias, dynamic prefix +
data/file suffix) stay safe. Regression rows added to test_permission_mode.py.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Gate GNU time -o, basicConfig/methodcaller/fileinput, and more SQL mutations
Another adversarial pass surfaced further consistent fail-closed gaps, each
reproduced with a benign control:
- Terminal: GNU time -o/--output/-a/--append truncate or append to a file with
timing output; time is a wrapper, so the flag is checked before the wrapped
command like env -C.
- Python auto mode: logging.basicConfig(filename=...) opens a log file for
write; operator.methodcaller("write_text"/...) hides a writer method behind a
string and is now treated as dynamic dispatch (like getattr/partial);
fileinput.input(..., inplace=True) rewrites a file in place (the default read
form stays safe).
- MCP read-named tools: UPDATE now matches quoted, bracketed, and
schema-qualified targets (UPDATE "users" / public.users / ONLY public.users /
[users] / `users` SET); SELECT ... INTO OUTFILE/DUMPFILE writes a server file;
and state-changing SQL functions inside a SELECT (pg_terminate_backend,
setval, pg_write_file, lo_export, ...) ask.
Benign controls (time ls / time -p, basicConfig(level=), methodcaller("upper"),
fileinput read, NL "update ... set", setval_col column, PL/pgSQL SELECT INTO
var) stay safe. Regression rows added to test_permission_mode.py.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Tighten auto-mode classifier comments
Collapse the multi-line rationale blocks in the permission classifier to one or
two lines each without dropping the exploit each branch closes. Comments and
whitespace only (no code change); the classifier tests are unchanged and pass.
* Retry transient SSE stalls in the tool-calling smoke probes
The tool-calling job flaked with a bare "TimeoutError: timed out": the
server-side python/bash probes stream over post_sse(), which (unlike
post()) had no transport-level retry, so a single stalled stream on a
shared CI runner hard-failed the whole step even though function calling
had already passed.
post_sse() now mirrors post(): a transport-level stall (stream open or a
mid-stream read timing out) is retried once with a fresh request capped
at 300s, while HTTP status errors still surface immediately. The
Linux _run_tool_probe caps each attempt at 360s and treats a stall that
outlives the retry as a failed attempt (rotate to the next seed) instead
of raising, and the web_search probe uses the same 360s cap. A genuine
server wedge still fails (the retry also times out), so real regressions
are not masked. Applied to the Linux, macOS, and Windows inference-smoke
workflows, which share the probe.
* Close five more auto-mode classifier gaps from review
Each reproduces with a benign control:
- Path constructor aliased through an attribute (P = pathlib.Path) now folds
like the bare-name alias, so (P('/etc') / 'passwd').read_text() asks while a
/tmp alias stays safe.
- Callable defaults that are not plain names now bind the parameter: an
attribute writer (def f(s=np.save)), an archive constructor, a captured .open,
and partial(open, mode='w') fold like the equivalent assignment; a benign
default (np.mean) does not.
- A dynamic piece inside a sensitive name (open('/et' + chr(99) + '/passwd'),
which folds to '/et\x00/passwd') now asks: the literals around each dynamic
segment are matched against a credential target with the segment as any run of
non-separator chars, so an all-dynamic ('1 + 1') or segment-spanning
(a + '/' + b) path stays safe.
- MCP read-named tools now ask on REFRESH MATERIALIZED VIEW and REINDEX; a
'refresh' column or natural-language 'refresh' stays safe.
- A writer/open alias handed to a higher-order invoker (map(open, names, modes),
starmap(np.save, ...)) is gated even without a direct call site; a benign
map(len, ...) is unaffected.
Regression rows added to test_permission_mode.py.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Default tool pills off on model load so tool execution is opt-in
resolveToolsEnabledOnLoad turned the web-search and code pills on for
any tool-capable model when the user had expressed no preference. Default
them off instead, so tool execution is enabled only when the person
clicks the pill to turn it on; a saved preference (on or off) is still
honoured, so a user who already enabled tools keeps them on.
* Gate mark/subscribe MCP verbs and qualified higher-order writer invokers
- A read-prefixed MCP tool name carrying mark / subscribe / unsubscribe
(get_and_mark_read, get_and_subscribe) now asks; a 'mark' substring inside
one token (list_bookmarks) stays safe.
- The higher-order writer check now also fires for a qualified invoker
(itertools.starmap(open, ...), functools.reduce(open, ...)), matching the
bare-name map/filter form; the writer-check on the first arg keeps a benign
itertools.starmap(len, ...) or itertools.chain(...) safe.
Regression rows added to test_permission_mode.py.
* Close more auto-mode gaps and align the ask confirm fold across paths
Each classifier change reproduces with a benign control:
- MCP read-named tools now ask on reply / notify verbs (get_and_reply_email,
list_and_notify_users), on catalog writes COMMENT ON / SECURITY LABEL / LOCK
TABLE and CREATE|DROP|ALTER POLICY, and on state-changing PostgreSQL functions
inside a read-shaped SELECT (nextval, set_config, pg_notify, the advisory-lock
family). A 'comment' column, a 'locks' table, and a 'nextval' column prefix
stay safe; the natural-language NOTIFY/SET ROLE statement forms are left out
because SET/NOTIFY overlap ordinary prose.
- Python auto mode now gates loader.exec_module (runs a module's code), archive
extractall (zip-slip file writes), the ensurepip / venv modules (install pip /
build an environment), and pydoc.writedoc. The Hugging Face login token
(~/.cache/huggingface/token and stored_tokens) is now a sensitive path, while
the rest of that cache (model data) stays readable.
- ChatCompletionRequest no longer overwrites an explicit confirm_tool_calls=false
when permission_mode='ask': the fold only self-enables the gate when the flag
is unset, so an explicit opt-out wins on the chat path exactly as it already
does via _permission_mode_confirm and the Anthropic pre-switch guard.
Regression rows added to test_permission_mode.py.
* Gate sort -T, xxd outfile positional, and the legacy HF token path
- sort -T / --temporary-directory writes spill files to a caller-chosen dir,
so it joins -o / --output in sort's unsafe-flag set.
- xxd [infile [outfile]] writes its second positional, like uniq; xxd now uses
the same second-positional-write handling (xxd in.bin out.hex asks, xxd
in.bin and xxd -c 16 in.bin stay read-only).
- The sensitive-path regex now also covers the legacy ~/.huggingface/token
location (optional leading dot), not just ~/.cache/huggingface/token; an
unrelated dir like myhuggingface/token stays safe.
Regression rows added to test_permission_mode.py.
* Catch multi-char SQL mutation targets, globbed credential names, digit outfiles
Three fail-open gaps in the auto-mode classifier, each with a benign control:
- SQL: the trailing word boundary on the MCP mutation regex meant a bare \w
stopped at the first character, so TRUNCATE users, GRANT SELECT ON t, and
REVOKE ALL ON t (multi-character names) slipped through while single-letter
targets matched. Match the whole identifier instead, and accept an explicit
AS alias on UPDATE (UPDATE users AS u SET). The implicit-alias form is left
out because it is indistinguishable from the prose "update <noun> <noun> set".
A truncate_log column and a grants table stay safe.
- A glob that resolves to a credential basename anywhere (cat ~/.huggingface/tok?n
-> token, cat proj/.netr? -> .netrc, cat repo/.aws/cred*) now asks; the fixed
target list only covered a handful of home paths. notes/dra?t.txt and
token_counts.tx? stay safe.
- uniq / xxd counted file positionals but skipped every numeric token to ignore
a flag value, so a file literally named with digits (uniq 123 out) hid the
output positional. Track each command's value-taking flags and consume only
the value, so uniq -f 2 in stays safe while uniq 123 out asks.
Regression rows added to test_permission_mode.py.
* Isolate the permission-mode loop tests from process-global state
The loop-driving tests (auto/off/full/bypass) drove run_safetensors_tool_loop
against a process-global approval registry (state.tool_approvals._pending)
keyed by a single shared session id, and read os.environ. Other backend test
modules mutate both, some at import time, so in the full-suite ordering a stale
pending approval or a leaked env var could make the loop deny or skip a call
these tests expect to run. It passed when the file ran alone but failed only in
the complete tests/ run on CI.
Add an autouse fixture that snapshots and restores os.environ and the approval
registry around each test, and give every _drive call a unique session id so a
leaked approval can never collide. Attach a compact event-stream dump to the
loop assertions so any residual full-suite-only failure reports what the loop
actually did instead of a bare diff.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: harden auto-mode classifier for recursive listers, sort file lists, aliased invokers, single-member extract
Close four fail-open gaps in is_potentially_unsafe_tool_call:
- terminal: tree/du (always recursive) and ls -R rooted at an absolute or
tilde path now ask, matching the existing grep/rg/find recursive-read gate;
relative walks stay safe.
- terminal: sort --files0-from=F reads the file list named in F, so it can
read arbitrary host files indirectly; added to sort's unsafe flags.
- python: track aliases of the higher-order invokers (m = map;
from itertools import starmap as sm) so an aliased invoker handed open/a
writer is still gated; a benign callable (map(len, ...)) stays safe.
- python: single-member archive extract (ZipFile/TarFile.extract) writes to
disk like extractall and is vulnerable to a crafted member path, so gate it.
Also update the stale _FakeExecuteTool in test_permission_mode.py to accept
the thread_id keyword that run_safetensors_tool_loop now forwards to
execute_tool after the main merge, which had broken the five tool-loop tests.
Adds regression rows covering each gap plus benign controls.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: normalize unknown permission_mode to 'ask' instead of a 422
The request models validated permission_mode with Literal[ask, auto, off,
full], so an unrecognized value from a newer UI/client was rejected with a 422
before the tool loops could apply their unknown -> ask fallback
(safetensors_agentic.py:464, llama_cpp.py:9001). That made the intended
forward-compat degradation unreachable at the API boundary for both Chat
Completions and the analogous Anthropic field.
Accept a plain string on both ChatCompletionRequest and AnthropicMessagesRequest
and normalize in a before-validator: None stays unset, the four known modes pass
through, and any other value degrades to the safest gate ('ask'), matching the
loops. Adds a regression test covering unknown/None/known across both models.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: close five more auto-mode classifier gaps
- terminal: xargs is no longer a safe wrapper. It appends arguments read from
stdin that the scan never sees, so `echo -o out /etc/passwd | xargs sort`
forwards to `sort -o out /etc/passwd` (a write + sensitive read) while only
the allow-listed literals are visible. Any xargs command now asks.
- terminal: ionice -p/-P/-u change the I/O priority of an already running
process / group / user instead of forwarding to a wrapped read-only command,
so `ionice -c 3 -p <pid>` now asks. ionice -c 3 <cmd> stays safe.
- MCP: gate ALTER SYSTEM, which persists PostgreSQL server configuration and was
not one of the DDL objects the mutation detector matched.
- MCP: a credential noun in a read-named tool (read_secret, list_tokens,
get_credentials, fetch_api_key) is a sensitive disclosure, so it asks even
without a mutating verb or a path/SQL argument. Scoped *_key nouns keep a
primary_key / keyboard lookup safe.
- render_html: no longer unconditionally safe. A static canvas still auto-runs,
but one whose HTML/JS reaches the network (fetch/WebSocket/remote script) asks,
since it can egress under the canvas CSP when artifact network access is on.
Its early provisional card is suppressed under the auto confirm gate, and the
confirm-without-stream guard now requires a stream when render_html is
selectable.
Adds regression rows and benign controls for each, and updates the render_html
provisional-card and confirm-gate tests to the new behavior.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: extend auto-mode gates for indirect file lists, dynamic lookups, HTML network loads, and Anthropic render_html
Follow-ups on the previous classifier round:
- terminal: wc/du/find --files0-from (and find's -files0-from primary) read a
NUL-separated list of input paths from a file, the same indirect mechanism as
sort --files0-from, so a crafted list reads arbitrary host files past the
literal path/root checks. Gate them like sort.
- python: a namespace lookup through a dict-style call (f =
__builtins__.__dict__.get('open'), globals().get('open'), vars(x).get(...))
can return open/eval/a mutator, so poison the bound name like getattr/subscript
lookups already are. An ordinary dict .get or os.environ.get stays safe.
- render_html: broaden the network detector so a canvas that loads a resource
via CSS url()/@import, srcset, or a root-relative (/path) or protocol-relative
(//host) src/href is treated as networked, not just fetch/WebSocket/remote
script. Relative ./x and url(#id)/data: refs stay static/safe.
- Anthropic /v1/messages: drop render_html from the unprompted-safe server-tool
set. Since it can prompt (networked canvas) and this channel invokes the loop
without confirm, selecting it under ask/auto/omitted now rejects like
terminal/python; off/full (or an explicit confirm opt-out) run it.
Adds regression rows and benign controls for each, plus an Anthropic route test.
* Studio: close six more auto-mode classifier gaps
- terminal: a glob that expands to a project .env (cat .e?v) now asks; .env
joins the sensitive glob-basename set, matching the literal-path gate.
- python: an open bound onto an attribute (box.f = open; box.f('out','w'))
is tracked by attribute name, and open invoked via .__call__
(open.__call__('out','w'), unwrapped to the underlying callable) is gated,
so neither slips past the name-based open-alias checks. Benign attribute
callables and .__call__ on non-writers stay safe.
- python: a namespace lookup via .get/.pop/.setdefault already covered the
builtins case; unchanged here.
- MCP: a mutating HTTP verb in a method/verb argument (get_url
{"method": "DELETE"|"POST"|"PUT"|"PATCH"}) now asks, so a generic HTTP
tool cannot mutate an external service unprompted; GET/HEAD stay safe.
- MCP: a credential/secret environment-variable value (get_env
{"name": "OPENAI_API_KEY"}) is treated as a sensitive read via the same
credential-noun match used for tool names; PATH/HOME stay safe.
- render_html: self-navigation sinks (location.assign/replace, window.open,
assigning a URL to (window.)location(.href)) join the network detector, so a
canvas that navigates itself to an external URL asks; location.reload() /
history.back() stay static.
Adds regression rows and benign controls for each.
* Studio: gate obfuscated canvas egress, sensitive-dir iteration, and MCP metadata-host reads
- render_html: strip block comments before the network scan so fetch/*x*/(...)
cannot hide egress, and match bracket-access forms (window['fetch'](...),
self['open'](...)). Line // comments are left alone so the // in an https URL
is not eaten. A comment-only canvas stays static.
- python: enumerating a directory outside the sandbox (Path('/etc').iterdir(),
os.scandir('/etc'), os.listdir('/home'), os.walk('/')) reads host filenames
the direct /etc/passwd checks would prompt for, so gate it when the target dir
folds to an absolute/tilde/sensitive path; a relative dir stays safe and an
unresolved dynamic dir is left to other checks.
- MCP: a read-named HTTP tool pointed at a cloud-metadata / link-local host
(fetch_url {"url": "http://169.254.169.254/..."}, metadata.google.internal)
reads instance credentials, so classify those URL arguments as sensitive,
mirroring the sandbox SSRF blocklist; ordinary and localhost URLs stay safe.
Adds regression rows and benign controls for each.
* Studio: gate meta-refresh navigation, pandas HTML/markdown exporters, absolute glob roots, and checksum verify mode
* Studio: gate starred open writes, builtins.__import__, computed render_html sinks, and procfs fd reads in auto mode
* Studio: gate remote worker canvases, huggingface_hub downloads, and write callables passed to user helpers in auto mode

* 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.

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

Update the fake MCP clients patched into mcp_client._client so their
call_tool signatures accept the keyword, keeping the stdio/servers MCP
test suites green.

* 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.
* Studio: show Hugging Face address on hover for Hub and online model rows
The model selector already shows an on-disk path tooltip on local rows,
but Hub and online rows showed only the bare repo id, and nothing at all
when there was no VRAM estimate. Add an optional hubUrl prop and a
hubRepoUrl helper that mirrors localPathTooltip, and surface
huggingface.co/<repo_id> on hover for the Discover, search, and
downloaded Hub rows. Local and VRAM tooltips are unchanged; the VRAM
tooltip now also appends the address line.
Closes#6382
* Studio: use a 700ms hover delay before the model-row tooltip
Give the model-row hover tooltip (the Hugging Face address, plus the VRAM
and local-path lines it shares) a 700ms open delay instead of showing it
instantly, so it does not flash while sweeping the mouse down the list.
* Fix/adjust GGUF tooltips for PR #6928

* Polish assistant message actions menu
Use the circle question mark (HelpCircleIcon) for the "See response
details" action instead of the file-database icon, and lowercase the
"Export as markdown" label.
* Align response details sheet icon
* Speed up Studio startup path
* Studio: recheck managed binary executability on preflight cache hit and ignore stale unauthenticated platform fetches
Preflight: a matching capability cache fingerprint no longer skips the
runnability check when the managed binary's executable bit was cleared
(size and mtime unchanged, since chmod bumps ctime not mtime). The cache
fast path now confirms the binary is still executable, otherwise it falls
back to the CLI help probe so preflight reports Stale and can repair,
instead of returning Ready and failing later at backend start. Adds a
regression test.
Frontend: now that first render is no longer gated on fetchDeviceType,
the initial unauthenticated health call can resolve after an
authenticated platform fetch. Guard the store so a late unauthenticated
or failed non-forced response cannot overwrite an already authoritative
device type, tunnel URL, or secure flag. Forced refreshes and the first
unauthenticated load are unaffected.
* Studio: use access(X_OK) for the preflight cache executability guard
A mode bitmask treats any execute bit as launchable, but the executable
bits can be set only for another owner or group, or be denied by an ACL,
so the current user could still hit PermissionDenied at launch and the
cached fast path would wrongly return Ready. access(X_OK) checks real
executability for the calling user, so an ownership or permission change
correctly falls back to the CLI help probe and the Stale repair path.
* Studio: ignore any stale non-forced platform fetch once authoritative
Extend the platform store guard so a non-forced health response never
overwrites an already authoritative result, not only unauthenticated
ones. With a saved token the post-render non-forced request can be
authenticated but older than a later forced refresh that already picked
up the tunnel URL and secure flag; if that earlier request resolves last
it would null those fields. Now any non-forced response is dropped once
the store holds a server-reported platform. Forced refreshes and the
first authoritative write are unaffected.
* Studio: run the managed CLI help probe before trusting the preflight cache
Restore running the managed CLI help probe before returning Ready from
the desktop capability cache, so a managed install whose venv interpreter
or a runtime dependency is broken (while path, size, mtime, and markers
are unchanged) is reported Stale for repair rather than proceeding to a
backend start that cannot spawn. The capability cache still skips the
heavier desktop-capabilities probe on a hit, so a warm cache runs one
probe instead of two. Removes the executable-access shortcut, which the
help probe now subsumes.

The live resource monitor and GPU readouts derive memory from binary byte
counts (bytes / 1024**3 for torch and psutil, MiB / 1024 for the nvidia-smi
path), which is GiB, but the UI labeled the values "GB". On a B200 this
showed "178.35 GB" for a card whose nvidia-smi total is 183359 MiB
(179 GiB), so it looked like memory was missing.
Relabel the measured RAM and VRAM readouts to GiB across the floating
monitor, the resources tab, the studio live GPU panel, the hub header, the
about tab and the onboarding summary. The numeric values are unchanged, so
the training GPU selection and memory-fit logic that read the same fields
are unaffected. Disk stays labeled GB because the backend reports it in
decimal GB (bytes / 1e9), and model file sizes and download progress keep
their decimal GB labels to match Hugging Face.
* 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 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

* Add a shared fits-on-device filter to the model selects
The chat model selector gains an Only show models that fit on this
device tick under its filter row, and the Hub page gains a matching
Fits device pill next to the sort menu. Both read one persisted
preference (unsloth_models_fit_on_device_only), so toggling either
applies to both.
The filter reuses the Recommended sort's existing fit math, extracted
into hfModelFitsDevice: size from safetensors metadata, GGUF param
count, or the repo name, against the 0.7 GPU + 0.7 RAM budget, with
unsizable models hidden. In the chat selector it extends the fit
filtering to the Trending and Recent sorts and to search results;
downloaded models stay visible regardless. An unknown device budget
keeps everything. The preference is cleared by Reset all local
preferences like the other picker toggles.

* Studio: HF model update detection and Update action for cached models
Surface an "Update available" cue and a managed Update action for cached
on-device models. /api/hub/update-status compares each cached main GGUF
file's local blobs against the remote main revision using set membership
across all cached revisions, so a repo that was already updated (and still
holds the old snapshot alongside the new one) is not falsely flagged.
The Update action re-downloads through the download manager so it shows in
the Downloads panel with progress and cancel. The frontend wires the Update
button into the GGUF, on-device, and model-selector cards and keeps the
quant label fully visible when the action buttons crowd the row.
Adds regression tests for the multi-revision update check.

* fix(studio/llama_cpp): disable trust_env on the loopback health probe
_wait_for_health() polls http://127.0.0.1:<port>/health with the default
httpx trust_env=True, so an ambient HTTP(S)_PROXY in the environment is
applied to the loopback request. A proxy that returns 503 for 127.0.0.1
makes every probe fail, so the loop runs until timeout and Studio load
hangs (trust_env=False returns 200 immediately).
Pass trust_env=False so the local readiness probe never goes through a
proxy. This mirrors the existing trust_env=False handling in the sibling
llama_http / external_provider HTTP clients.
* test(offline_gguf_cache): accept trust_env kwarg in fake_get mock
_wait_for_health now calls httpx.get(..., trust_env=False); update the retry test's fake_get to accept the kwarg so it doesn't raise TypeError.

* Studio: quick eject from the model selector
Add a one-click eject shortcut to the loaded-model pill so users do not
have to open the picker to unload a model.
- The loaded-status indicator shows a green checkmark at rest and swaps to
a red eject icon on pill hover, with an "Eject model" tooltip. Clicking
it ejects without opening the picker.
- On Device tab now uses the placeholder "Search local models" instead of
"Search Unsloth models".
- The picker's "Eject model" button uses medium font weight.
* Studio: drop unused group/eject marker class on the eject control
* Studio: make the inline eject control valid HTML
The eject shortcut was a focusable span (role/tabIndex) nested inside the
trigger button. A button's content model forbids focusable descendants, so
make it a plain decorative span (aria-hidden, no role/tabIndex) that keeps
the mouse shortcut. Keyboard and screen-reader users eject via the picker's
"Eject model" button.
* Studio: disable the inline eject shortcut on touch devices
On touch (no hover) the red eject icon and title tooltip never reveal, so
tapping the loaded pill could unload the model with no visible affordance.
Add [@media(hover:none)]:pointer-events-none so taps fall through to the
trigger and open the picker; touch users eject from the picker instead.

Local models in the Studio Hub tab (Custom folders, LM Studio, and
Local models sections) did not reveal their on-disk path on hover,
unlike the Fine-tuned rows which already do. Each of these rows maps
over a LocalModelInfo with a required path, so pass tooltipText built
from the model name and path via a small shared localPathTooltip
helper, matching the existing FT-row tooltip format.

The fade is recomputed on a group's open/close state flip, but the groups
animate their height, so it measured scrollHeight mid-animation and the
fade could vanish at random. Re-measure on the collapsible animationend,
and add the missing pinnedOpen dep to the recompute effect.
Footer padding moves from pt-3 pb-4 to pb-3 with a conditional top: pt-1.5
when the update card is shown so the fade hugs it, pt-2.5 for the profile
on its own. When the update card is shown, shorten the fade above it
(h-10 -> h-3) so the list reads closer to the card.
* studio: add sidebar update button (static design only)
Adds a clock-icon update card above the account button in the sidebar footer. Visual/layout only; update detection and click behavior are wired in follow-ups.
* studio: show installed version in sidebar update card + collapse to icon
Replaces the placeholder version with the real installed app version via @tauri-apps/api/app getVersion() (Tauri-only; hidden in browser). Collapsed sidebar now shows just the clock icon instead of hiding the card.
* studio: open Settings About (update section) when the sidebar update card is clicked
* studio: i18n the sidebar update button label and add aria-label
Address Gemini Code Assist review on #6545:
- wrap the hardcoded "Update available" label in t() (shell.updateAvailable,
en + zh-CN), matching the rest of the sidebar
- add aria-label so the collapsed icon-only button has an accessible name

Keeps the i18n label/aria-label; desktop (Tauri updater) detection not wired yet.

* studio: report the true reasoning duration and fix the Stop button for thinking models
For a local GGUF the "Thought for N" label was timed entirely on the client by a
brittle edge-detector, so an always-think model (Qwen3 MTP) that buffers its whole
reasoning and flushes it in one chunk showed "1 second" instead of the real
minute-plus. The client cannot time reasoning it receives atomically, so make the
timing backend-authoritative.
Backend: generate_chat_completion_with_tools measures wall-clock reasoning and
emits a Studio reasoning_summary event (duration_ms) at the moment reasoning ends
-- the first answer token, or end-of-stream for a reasoning-only reply -- for both
the tool-detection pass and the final-answer pass. Timing resets per tool
iteration so the final answer's thinking time wins on the client (which takes the
latest reasoning_summary). routes/inference.py forwards the event in the GGUF tool
stream.
Frontend: parse the reasoning_summary SSE into a _reasoningDurationMs chunk and
use it as the authoritative reasoning duration (last write wins), clamped to >= 0
and guarded to a finite number so a malformed or proxied chunk cannot produce a
NaN label; the persisted value wins for the final "Thought for N" label, with the
previous live timer kept only as a fallback when no metadata arrives.

* Chat: match reasoning thinking icon to the composer bulb
The reasoning "Thinking..." indicator used lucide's LightbulbIcon while
the composer thinking toggle used a custom bulb glyph, so the two did not
match. Move that glyph into lib/bulb-icon.tsx and use it in both places
so they render the same icon.

* Studio: refresh chat tour for the redesigned model picker
- Pick a model step describes the Recommended and On Device tabs instead of the old Hub and Fine-tuned split
- Find a model step (was Two tabs) covers Unsloth search vs Search Hub, the format and sort filters, and the OOM tag
- Settings step now anchors to the run settings panel on the right. The old anchor sat on the open settings button, which unmounts when settings opens, so the tooltip lost its target and drifted left
* Add guided tour step for the composer + menu
Polish for the in-chat model picker popover and its guided-tour step.
- Search box placeholder reads Search Unsloth models, matching the Unsloth-only listing.
- Search Hub button shows a Search all models tooltip on hover.
- Floating Eject pill moves 1px lower so it sits closer to the bottom edge.
- Results list max height trimmed by 1px (21rem to 335px) from the bottom only.
- Chat guided tour Two tabs step updated to describe Unsloth-scoped search plus Search Hub for all of Hugging Face.
The chat and sidebar scroll-fade overlays ended their gradient at the
`transparent` keyword, which is transparent black. Safari 27 Beta
(Liquid Glass) interpolates an opaque colour to transparent black
through a grey midtone, so the fades render as two solid grey bands
(top of the chat and above the composer).
Fade each gradient to the theme colour at zero alpha instead, so every
step keeps the same hue and no grey can appear. Fixes#6457.

* Studio: redesign Select model dropdown to match Hub design
Make the chat Select model picker easier to scan by reusing the Hub
on-device card's visual language.
- Rows now split owner/name, add a param chip, a DotTag format pill,
a tabular size, and a Loaded marker on the active model.
- Hub models / Fine-tuned tabs reuse the Hub's exact .hub-tab-toggle
styling (selectors extended in hub.css to the selector menu).
- Add a Downloaded / Recommended / Custom section toggle on the Hub
tab to filter the list.
- Widen the popover and nudge the scrollbar toward the edge.
* Studio: move section toggle below search, size tabs to label
Put Downloaded / Recommended / Custom under the search bar in their own
row so Hub models / Fine-tuned no longer wrap. The section toggle uses a
smaller font and sizes each tab to its label instead of equal widths.
* Studio: extract pure row-meta helpers into their own module
Move splitRepoLabel, classifyMetaToken, and parseMetaTokens out of
pickers.tsx into row-meta.ts. No behaviour change; keeps the presentation
logic free of React/DOM deps so it is easy to test in isolation.
* Studio: content-size the source tabs and add section icons
Size the Hub models / Fine-tuned tabs to their labels (with side
padding) like the section toggle, instead of stretching full width. Add
a leading download, star, and folder icon to Downloaded, Recommended,
and Custom.
* Studio: stop source tabs stretching and hide empty Fine-tuned tab
The popover is a flex column, so the fit toggle stretched full width;
add w-fit/self-start so it sizes to its content. Also hide the
Fine-tuned tab when there are no fine-tuned models, defaulting to Hub
models.
* Studio: keep only fine-tuned models in the Fine-tuned tab
Local models (LM Studio, Ollama, custom folders) carry source "local"
and already show in the Hub tab's Downloaded / Custom sections, so
exclude them from the Fine-tuned tab and from its visibility count.
Extract the tab rules into source-tabs.ts.
* Studio: show local providers under Downloaded, Recommended first
Show LM Studio and other local provider models in the Downloaded
section in all modes (was chat-only). Put Recommended first and make it
the default section. Add a little more space below the search bar.
* Studio: make Recommended a sortable live Unsloth listing
Replace the static Recommended list (and its collapse chevron) with a
sort dropdown over Unsloth's own models: Recommended, Trending, Most
likes, Downloads, Recently updated. Recommended shows recently uploaded
GGUF/MLX models that fit the device (hidden if they do not); the other
sorts list all Unsloth models, badged but never hidden. Adds a sort
option to useHfModelSearch and a pure recommended-fit helper.
* Studio: size Recommended models from the repo name when metadata is missing
GGUF and MLX repos rarely expose safetensors metadata, so a large model
with no size could pass the Recommended fit check because unknown size was
treated as fitting. Parse the parameter count from the repo id, including
the Gemma E series, and hide anything we still cannot size.
* Studio: detect model capabilities and family from HF tags
Thread tags and the pipeline tag through the model search results and add a
pure helper that infers vision, reasoning and audio plus the architecture
family, falling back to repo-name keywords when tags are absent.
* Studio: add row details and inline section sorting to Select model
Give each model row more detail and make the Hub sections easier to scan:
- Show vision, reasoning and audio badges plus the architecture family tag
on each row, alongside the params, format and size.
- Drop the redundant unsloth/ prefix on the Recommended rows.
- Rename the Recommended section tab to Unsloth and enlarge the section tabs.
- Move the sort dropdown inline to the right of the tabs at a fixed width.
- Add Recent, Size and Downloaded sorting to the Downloaded and Custom tabs.
- Remove the header icons, pad the subheadings, and grow the list height.
* Studio: tune the Select model sort dropdown and trim row badges
- Recommended now lists the most recently created Unsloth repos.
- Narrow the sort dropdown, remove its border, and truncate long labels.
- Tighten the gap between the section tab icons and their labels.
- Remove the architecture family tag from rows since it repeats the name.
* Studio: extract the PillTabs toggle into a shared module
Move the segmented pill toggle out of the model selector into its own file so
the Hub picker can reuse it for a format filter without duplicating the markup.
* Studio: fix Recommended infinite scroll and add a format filter
- Re-attach the scroll observer on each loaded page so a filtered Recommended
list keeps paging until the viewport fills instead of spinning forever with
nothing new appearing.
- Add an All / GGUF / MLX / Safetensors toggle on the Unsloth listing that
filters every sort.
* Studio: default Recommended to Trending, rename Downloaded to On Device, and fade the scroll edge
Sort: default the Recommended view to Trending and add a Name option to
the On Device / Custom sort. Recent now orders by last load time while
Downloaded orders by file date, tracked in localStorage (model-usage.ts).
Formats: show the format filter on all three tabs (Unsloth, On Device,
Custom), exclude mobile GGUF builds from Recommended, and flag GGUF rows
that exceed the device with the same OOM badge as safetensors.
Polish: download-icon badge on already-downloaded Recommended rows, the
hugeicons view stroke-rounded vision badge, Search all models placeholder,
matched popover padding, and a top-edge mask fade once the list scrolls.
* Studio: size GGUF repos from gguf metadata so large ones flag OOM
Repos with no <n>B token in the name (Kimi, MiniMax) had no param count
and so never showed an OOM badge. Request the gguf expand field from
Hugging Face and read gguf.total, so those repos get a param chip and an
OOM badge when they exceed the device budget.
Keep the row name full contrast when over budget (the OOM badge already
signals the fit), shorten the format and sort dropdowns, narrow the
popover, and rename Recently updated to Recent and All formats to All.
* Studio: address selector review feedback
Add WAI-ARIA roving tabindex and Arrow Left/Right navigation to the pill
toggle so only the active tab is in the tab order. Keep the chat-only
GGUF/MLX filter for every Recommended sort, not just Recommended, so
chat-only users do not see unrunnable checkpoints under Trending. Feed
both listings' GGUF hints into repo detection so a tag-only GGUF in
Recommended expands variants instead of loading as a checkpoint.
* Studio: scope Select model search per tab and add an MLX tag
Search is now per section. The Unsloth tab searches the Unsloth HF
listing only, On Device filters downloaded and LM Studio models by name,
and Custom filters custom-folder models, each with its own empty state.
MLX repos get an MLX pill mirroring the GGUF tag. Downloaded quants in
the Unsloth and search lists get the same delete action as On Device.
Also: revert the model name to normal weight, narrow the popover to
558px so the format and sort dropdowns sit one gap-2 from the tabs,
tighten the dropdown menus to match the Projects activity Select, and
make the empty On Device state name the active format filter.
* Studio: show local ./models on the On Device tab so they stay selectable
Models under the local models directory (source models_dir) flow in as local
models but were dropped from every list: filtered out of Fine-tuned and never
re-added by the Hub picker, which kept only LM Studio and custom-folder
sources. Capture them in the local refresh and render a Local models group on
the On Device tab, with the same format, search, and chat-only GGUF rules as
the other local groups.
* Studio: add a Hub button beside the Select model search bar
Adds a Hub button next to the search bar that opens the full Hub Discover
page to browse more models. Styled like the section tabs (rounded, no
border, soft shadow with a faint top layer) and darkens on hover. Also
nudges the format and sort dropdown chevrons a touch toward the edge.
* Studio: align Select model padding and tighten the format pills
Sizes the popover to the tab cluster so the left and right padding match,
and drops the top row below the rounded corner so the Hub button lines up
with the Trending dropdown. Gives the Hub button a fixed width, lets the
list scrollbar sit inside the box, and shrinks the format pill dot with a
tighter dot-to-label gap.
* Studio: label the Hub button Search Hub and match the dropdown width
Renames the button to Search Hub, sets its width to the format and sort
dropdown width so it lines up above them, and tightens the icon gap.
* Studio: drop the vision and reasoning row badges to declutter
Removes the vision and reasoning capability icons from the model rows so
they read cleaner. Audio is kept.
* Studio: add a safetensors pill, hide diffusion models, eye on Vision
Gives safetensors rows a format pill and size so their meta matches GGUF
and MLX, drops image and video diffusion models from the listing since they
cannot run in chat, and shows an eye icon next to the Vision tag. Also
removes the em dashes from the Projects export and import labels.
* Studio: gate recommended folders on real weights and polish the selector
Only show a Recommended chip once the well-known dir actually holds
weights, so an empty LM Studio or Ollama scaffold no longer suggests
itself. _dir_has_downloaded_model checks for a GGUF/safetensors file or
a non-empty Ollama manifests store, with a bounded walk.
Selector polish: round the popover and option menus a touch more,
lighten the OOM badge in dark mode, soften the inner dropdown shadow,
even out the padding, and lift the toggle track and field triggers so
their edges read against the popover.
Also catch CogVideoX in the diffusion name fallback.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: align the dark Select model panel with the sidebar
Match the popover, fields, dropdowns, tab toggle and row states to the
sidebar surface and accent so the dropdown reads as one piece in dark
mode. The active tab pill and Search Hub button sit a touch lighter
than the track, and the inner option menus drop their drop shadow for a
flatter look. Light mode is unchanged.
* Studio: re-derive the Select model tab on open
The picker remounts each time the dropdown opens, but the source tab
state did not, so a persisted fine-tuned or connected selection that
only lands in its list after an async load would reopen on Hub. Reset
the active tab to the selection-derived default on the open edge, while
still letting the user switch tabs freely within a session.
* Studio: fold Custom into On Device and polish the picker
Merge the Custom tab into On Device so custom folders sit right below
the downloaded models, with a folder shortcut on the group header.
Rename the first Hub tab to Recommended, give the format dropdown
colored dots, even out the tab row spacing, and tighten the popover
width. Align the folder browser with the app dialogs (soft surface,
roomier padding, green confirm, grey hover).
* Studio: fix On Device controls and nudge the folder browser close
The Hub redesign merge dropped the old Search Hub button styling, so the
On Device search row rendered flat. Point the search input and Search
Hub button at the shared .field-soft surface so they match the rest of
the Hub controls, and lift the folder browser close button slightly.
* Studio: run the Select model search on the Hub search stack
Point the picker at the Hub's useHubModelSearch and useHubInfiniteScroll
instead of its own useHfModelSearch/useInfiniteScroll, scoped to unsloth
so the listing matches the old one. Both the search and the recommended
feed now share the Hub implementation, so there is one search path. The
Hub result folds GGUF params into totalParams, so the dead ggufParams
fallback is dropped.
* Studio: trim the recommended sort to Recommended, Trending, Recent
Drop Downloads and Most likes from the sort dropdown.
* Studio: give the section tabs room off the rounded edge
The fit-mode toggle wrapped the tabs with no inset, so On Device sat
tight against the rounded-full edge. Add a small horizontal inset and
widen the popover a touch to fit it.
* Studio: drop the legacy HF search hooks for the Hub ones
Migrate the training model and dataset sections, export page, onboarding
steps and recipe dataset combobox off useHfModelSearch, useHfDatasetSearch
and useInfiniteScroll onto the Hub equivalents, scoped to unsloth so the
listings match. The picker reads recommended param counts off the search
results it already has instead of a separate fetch. Removes the duplicate
search stack: use-hf-model-search, use-hf-dataset-search,
use-hf-paginated-search, use-infinite-scroll, use-recommended-model-vram
and the old lib/hf-cache.
* Fix model selector section toggle proportions
Remove the fit-mode track inset so the active pill sits flush to the
track edge, matching the Hub's segmented controls.
* Tighten model selector width and tab padding
Reduce the popover width so the right edge aligns with the row, and
widen the fit-mode tab padding so On Device clears the track edge.
* Refine Recommended formats, sort width and tab padding
Recommended now suggests GGUF anywhere and MLX only on Mac, never
safetensors. Size the sort dropdown to its label so Recommended no
longer truncates, and match the On Device trailing gap to the active
pill's leading inset.
* Flush section toggle and match dropdown font to Search Hub
Drop the trailing track pad so the active pill fits the track exactly
at either end. Size the sort and format dropdown text to text-xs like
the Search Hub button, and clip long labels without an ellipsis.
* Fix sort menu checkmark overlap and lock dropdown widths
Keep the option's right padding so the selected checkmark no longer
overlaps the label, and let the open menu expand to fit it. Set the
format and sort triggers to a fixed width matching the Search Hub
button so they always line up.
* Keep section toggle and dropdowns on one row
Drop the wrap and size the Search Hub button, format and sort dropdowns
to a shared 100px so they stay equal width and fit on one row without
widening the box.
* Studio: pre-load inference settings dialog with native context
Add a gear on downloaded GGUF quant rows that opens a settings dialog
to adjust inference parameters before loading a model:
- Context length, KV cache dtype, speculative decoding and tensor
parallelism, all written to the runtime store the load call reads.
- Settings can be remembered per model in localStorage.
- The context slider ceiling and "Model supports up to N tokens" come
from the model's native context, read from GGUF metadata and returned
by /api/models/gguf-variants once a variant is downloaded.
Also drop models Studio can't run for chat (diffusion, image, video)
from the recommended feed and Hub search, plus minor selector polish
on row hover padding, Search Hub and dropdown widths, and tab spacing.
* Studio: model selector polish and memory-aware load warning
Search and listing:
- Drop the "Recommended" and "Hugging Face" section labels while
searching so results read as one list; keep the format and sort
dropdowns visible so search results can still be sorted and filtered.
- Request gguf metadata in the Hub listing so GGUF repos report a
parameter count, restoring the OOM badge for repos without a size
token in the name (Kimi, MiniMax, GLM).
Load settings dialog:
- Warn when weights plus the KV cache at the chosen context exceed
available memory. The KV size is sized by the backend's
architecture-aware estimator via a new kv-cache-estimate endpoint;
the budget uses VRAM plus system RAM. Best-effort, no warning on
failure or on auto context.
- Context Length placeholder reads "auto"; dark background slightly
lighter.
Other:
- Clicking the Custom Folders header opens the folder browser; its
title now reads "Select folder to detect models".
- On Device sort lists Downloaded last.
- Smaller chat template editor font; rounded wrapper clips the prompt
and template editor scrollbars so the right corners stay round.
* Studio: fix load dialog memory warning budget and KV dropdown width
- The memory warning never fired without a discrete GPU. useGpuInfo
returned zero system RAM in that case, so the budget was always zero.
Surface system RAM even when no GPU is present (Mac unified memory),
and have the load dialog read memory directly instead of through props.
- Give the dialog fields shrink-0 so the KV Cache Dtype value (e.g.
q8_0) is not squeezed and clipped by the row.
* Studio: fold fine-tuned models into On Device tab
Remove the Hub models and Fine-tuned source tabs. Fine-tuned models now
show as a section in the Hub tab's On Device view, above Custom Folders,
with the Train icon and a collapse toggle. The section only appears when
the user has fine-tuned models. With no external providers the lone Hub
tab hides its own toggle.
Also: tick-circle Show hidden checkbox and drop the divider above Eject;
keep run settings load params (KV cache dtype, speculative, tensor
parallel) from being clobbered by a mid-load status poll.
* Studio: stage load settings in the sidebar with a Load on selection toggle
Replace the pre-load settings popup with a staging flow in the Run settings
sidebar. The gear on a downloaded quant row now stages the model and opens
Run settings with Load model and Cancel buttons, so options like context
length, KV cache, speculative decoding and tensor parallelism are set before
the model loads. A "Remember these settings" tick reuses them next time.
Add a global Load on selection toggle in Settings, Chat tab (default on).
On: Unsloth auto-picks the best settings for your hardware and loads on
selection. Off: picking a model stages it in Run settings to customize first.
The gear always stages, regardless of the toggle.
Other polish in this change:
- Fine-tuned models live under the On Device tab, with a train icon on the
header that jumps to the Fine-tuned section.
- Default to the On Device tab when downloads exist, otherwise the last used
section.
- Standard Unsloth tooltips on the train, folder and gear icons.
- Request the gguf param count on every Hub listing fetch so Kimi, MiniMax
and GLM show a size badge.
- Search Hub hover state, scrollbar position and minor spacing fixes.
Remove the old inference load settings dialog.
* Studio: always show the fine-tuned shortcut and smooth out the picker
- Fine-tuned section and its train shortcut now always show on On Device,
with an empty state when no fine-tuned models exist yet.
- Folder icon on the header jumps to Custom Folders instead of opening the
browse popup, matching the train shortcut.
- Folder browser keeps the list mounted and dims it while refetching, so
toggling Show hidden or changing folders no longer flashes.
- Drop the tooltip hover grace area in the picker so moving between the
train, folder and gear icons switches the tooltip at once.

* Studio: add quantization display options and drop the fine-tuned empty text
- Settings, Chat: 'Expand quantizations' toggle. On expands every On Device
GGUF model's quantizations by default; off keeps them behind a click
(default).
- Settings, Chat: 'Show all quantizations' toggle. On lists every quant
including ones not downloaded (default); off shows downloaded only.
- Remove the empty-state line under the Fine-tuned header; the header still
shows on its own.
* Studio: let expanded quantizations collapse on click and split the On/Off help
- With Expand quantizations on, clicking an On Device model now collapses or
re-expands its quantizations. The collapse state is in memory only, so it
resets on reload and when the setting is toggled.
- Put the Off sentence on its own line in the quantization setting descriptions.
* Studio: reorder chat settings and rename the model section
- Rename the Models section to Select model settings and move it above the
Chat menu section.
- Trim the section and Load on selection descriptions.
* Studio: tighten the On/Off lines in the model setting descriptions
Use a line break instead of separate spans so the On and Off lines sit on
consecutive lines without the extra paragraph gap.
* Studio: top-align the Load on selection toggle
Add an alignTop option to SettingsRow and use it so the toggle sits at the top
of the row next to the label, not centered against the tall description.
* Studio: put the gear hint and example chip on one line
Move the gear example chip inline with its label so it reads as a single line
instead of wrapping onto its own row.
* Studio: move the New badge from API keys to Chat settings
Add the New badge to the Chat settings tab and drop it from API keys.
* Studio: line the Load on selection toggle up with the first description line
Offset the top-aligned control past the label row so it sits next to the On
line instead of the label.
* Studio: label the chat menu item Chat with Files (RAG)
Rename the Chat with Files entry in the chat menu settings to clarify it is RAG.
* Studio: drop the pill around the gear example so it fits on one line
Remove the background and padding from the gear example chip so it sits inline
with its label at a lower height.
* Studio: fold the gear example into the description line spacing
Render the gear example inline in the same text block so its line spacing
matches the On and Off lines instead of an extra flex gap.
* Studio: scope Show all quantizations to On Device only
Gate the downloaded-only filter on an onDevice flag so Recommended and other
browse lists always show every quant, and note On Device in the setting copy.
* Studio: tidy On Device GGUF rows
- Drop the redundant Quantizations subheading under On Device models.
- Relay GGUF vision support up to the model name as a Vision badge instead.
- Drop the repo size from On Device GGUF model rows since the quants already
show their size.
* Studio: pin the eject button and tidy General settings
- Move Eject loaded model out of the scrollable list into a centered footer so
it stays in view no matter how far the list is scrolled.
- Space out and center the gear example in the Load on selection description.
- General: drop the duplicate Unsloth version section, move llama.cpp
notifications above Helper LLM, and note new models in its description.
* Studio: add left padding before the gear example
Nudge the gear example away from its label with a small left margin.
* Studio: make the eject footer a sticky bar over the list
Pin Eject loaded model to the bottom of the scroll area with the menu
background so rows scroll under it, and drop the divider line.
* Studio: drop the eject footer background, keep it a sticky button
Make the sticky eject a centered transparent button so it coexists with the
rows scrolling behind it. The wrapper ignores pointer events so only the button
is clickable.
* Studio: give the eject button a solid background
Add the menu background, a border and a soft shadow to the sticky eject button
so it reads as a floating button over the list.
* Studio: restore the eject footer block, keep hover on the button only
Bring back the full-width menu background behind the sticky eject footer, but
keep the button compact and centered so the hover stays on the button.
* Studio: show the vision badge on On Device rows without expanding
- cached-gguf listing reports has_vision (mmproj present), so the badge shows
on the model name without opening the quantizations.
- Make the vision badge icon-only with a tooltip: "This model can process
image inputs". Falls back to the expander-reported value on older backends.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Make LM Studio and Local models sections collapsible
* Fade the eject footer instead of a solid block
* Wrap the vision badge in a bordered pill
* Taller model list with the eject footer pinned to the bottom
* Use purple for the vision badge to set it apart from GGUF
* Reduce the model list height
* Make the eject button inline with no background block
* Match the vision badge color to the Hub indigo tone
* Shorten the model list and square off the format tags
* Pin the eject button so it floats at the bottom of the list
* Give the floating eject button a tinted background
* Add bottom clearance so the list ends on white space under the eject button
* Match eject button to the menu background and unify the settings gear icon
* Move eject below the list and match its shadow and dark background
* Drop the min height so short model lists leave no white space
* Remove the eject button fill so it never covers the list
* Nest dropdown hover radius inside the menu corners
* Float the eject pill again and fix sort dropdown hover radius
* Make the eject button opaque in both themes on hover and dark
* Trim the model menu bottom padding so it stops clipping the last row
* Match dark eject background to the Search Hub button and pad row indicators
* Fade the model list bottom edge while rows sit below the fold
* Lift the eject button and trim the section toggle right padding
* Nudge the model list taller and run the bottom fade to the box edge
* Nudge the model list slightly taller
* Remove the eject button shadow
* Align the eject button to the right
* Widen the Search Hub and dropdowns and right-align them
* Seat the eject button at the base and restore On Device right padding
* Reduce the Search Hub and dropdown width by 4px
* Widen the model menu so the section toggle keeps its padding
* Make the eject button an icon-only button with shadow
* Tighten section tab padding to cut the grey between tabs
* Revert section tab padding back to px-3
* Remove the section toggle trailing padding
* Add an eject button beside the model selector trigger
* Shrink the in-list eject button to a smaller proportional size
* Raise the in-list eject button
* Make the trigger eject a bare icon next to the dropdown arrow
* Revert eject back to the labeled button on the right
* Place the format and sort dropdowns next to the section toggle
* Raise the eject button and shorten its label to Eject model
* Widen the gap between the toggle and dropdowns slightly
* Align Search Hub with the last dropdown via a shared-width grid
* Narrow the model menu for symmetric padding
* Stretch the search row so Search Hub lines up with the last dropdown
* Inset the list so the right padding matches the left
* Right-align dropdowns and full-width search so Search Hub meets the last dropdown
* Pack section toggle and dropdowns with a uniform gap
* Inset search row so Search Hub aligns with the Trending dropdown
* Trim model menu right padding to match the left
* Nudge model list scrollbar inward
* Move eject button to the bottom left with a light shadow
* Shorten show all quantizations description
* Keep eject button right-aligned, nudged in from the edge
* Move Connected into the section toggle as a cloud-icon tab
* Align eject button with the format tag edge
* Right-align Connected layout so Search Hub meets Trending
* Download selected models through the Hub download manager
* Add Other models section for non-Unsloth downloads
* Add directions icon and shortcut for Other models section
* Space out subheadings and gate Other models on non-Unsloth downloads
* Use direction-right icon for Other models
* Use flag icon for Other models
* Widen Connected menu so dropdowns align with Search Hub
* Model selector: truncate long quant labels and tidy layout
- Hub GGUF card: truncate long file-path quant labels with an ellipsis
instead of overflowing the row.
- Connected layout: left-pack the dropdowns and size the box so the last
dropdown's right gap matches the pill's left gap, with Search Hub on its edge.
- On Device: show MLX/Safetensors with the size on non-GGUF rows.
- Connected list rows use the same grey hover as the tabs; the selected
section tab no longer shows a hover change.
* Model selector: drop stale custom section on restore
A persisted custom section value no longer maps to a tab, so restoring it
opened the picker to an empty view. Fall back to recommended instead.
* Model selector: align the non-connected search bar with the All dropdown
Nudge the non-connected box width so the search bar's right edge meets the
All dropdown, which lands Search Hub on the last dropdown's edge.
* Studio chat model selector: remember last tab, route non-GGUF downloads through Hub, stack overlays
- Restore the last Hub section (Recommended / On Device) on every open instead of always snapping to On Device when downloads exist.
- Route uncached non-GGUF repos (safetensors / MLX) through the Hub download manager via a snapshot download, so every model download shows in the bottom-right indicator and follows Load on selection like GGUF.
- Allow safetensors in Recommended on Mac (they run locally there now), and honor the Safetensors format filter instead of dropping it via the recommendation default.
- Stack bottom-right overlays in one column so the download panel and banners never overlap.
- Add evenly spaced divider lines between the On Device subheadings.
- Pad the bottom of the list so the floating Eject pill never covers the last row.
* Studio downloads panel: widen left padding on header and rows
Bump the left inset to pl-4 while keeping pr-3 so the collapse and cancel buttons stay put.
* Studio: update cached-gguf route tests for the has_vision field
list_cached_gguf now returns has_vision per row (vision badge on On Device);
the expected dicts were missing it. True for the mmproj vision repo, False elsewhere.
* Studio: keep MLX/safetensors selectable in chat-only Mac search
The empty Recommended view allows GGUF plus MLX/safetensors on Mac, but the
curated and HF search lists dropped non-GGUF in chat-only via a GGUF-only filter,
so typing a query hid runnable Mac models. Reuse isRecommendableFormat in both
lists so search matches the empty view (chat-only non-Mac stays GGUF-only).
* Model selector: restore global model search and fix GGUF/device-fit regressions
- Search: training, export and onboarding pickers searched only the unsloth org
on a typed query. Restore the prior behavior (global Hub search with unsloth
floated first when a query is typed, curated unsloth listing when empty).
- Recommended browse: the GGUF/MLX-only gate ran before the format filter, so
the Safetensors filter and the Trending/Recent sorts always came back empty.
Apply that gate only for the Recommended sort and chat-only mode.
- GGUF metadata: request the gguf expand field through listModels so repos with
no size token in the name (Kimi, MiniMax, GLM) report a param count for the
size and OOM badge.
- Local GGUF: custom-folder and standalone ./models/*.gguf files now load
directly with the GGUF marker instead of dead-ending in the variant expander,
and scanned GGUF folders are classified via a backend model_format hint.
- Device fit: use system RAM in the budget on unified-memory hosts, and keep MLX
rows selectable on chat-only Macs.
- kv-cache-estimate: resolve the quant from the snapshot-relative path, skip MTP
drafter files, and prefer the most complete snapshot (mirrors the variant
scanner). Bound the Ollama manifest walk.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Model selector: classify suffixless local GGUF folders consistently
Complete the model_format plumbing so a GGUF folder is detected and loaded
through the same GGUF path that the format filter already uses:
- _scan_models_dir: a config.json no longer disqualifies a folder whose only
weights are .gguf, so HF GGUF repos shipping a config still classify as GGUF.
- _scan_lmstudio_dir: emit model_format for every GGUF row (LM Studio dirs
rarely carry a -GGUF suffix), via a shared _dir_model_format helper.
- Custom Folders and LM Studio rows: use localModelIsGguf (the same helper the
filter uses) so the row label, expand-vs-direct-load, and isGguf flag agree;
a suffixless GGUF folder no longer filters as GGUF but loads as non-GGUF.
Adds tests/test_local_model_format.py covering the classification rule.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio model selector: tighten section spacing
Trim each subheading's gap to its rows (pb-1.5 to pb-1) and pull the On Device
heading block tight to the controls while Recommended keeps a little top room.
* Hub: format filter fix, sort defaults, avatar and layout polish
- Format dropdown now filters the feed's Latest list too, so the default
GGUF hides fp8/safetensors and picking a format changes the rows.
- Latest Unsloth Models sorts by newest created, not recently updated.
- Sort dropdown order: Newest, Trending, Most downloads, Recently
updated, Most likes.
- Unsloth uploads with no upstream provider logo show the Unsloth avatar
instead of a colored initial.
- Owner scope pill gets a little more room before the chevron.
- README detail column lines up with the top bar (both-edges gutter).
- Long file-path quant labels truncate instead of overflowing the row.
- Model list keyboard nav no longer clips the focus ring.
- Run settings sheet: restore the Remember settings toggle and larger
Load/Cancel buttons on the staged load flow.
* Hub: hide the RAG embedding model from browse previews
The Hub discover feed and chat model selector pull from the Hugging Face
listing on the client, which the backend _is_hidden_model filter never
touches, so the RAG embedder (unsloth/bge-small-en-v1.5-GGUF) and the
llama.cpp validation probe leaked into the lists.
Added isHiddenModelId mirroring the backend needles and filtered it out of
the discover rows, the trending feed, and the selector's recommended and
Hugging Face search lists. Per-repo file and download views are untouched,
so the model is never deleted and a reinstall still shows it as already
downloaded.
* Studio: skip hidden dirs when checking a folder for downloaded models
_dir_has_downloaded_model walked the tree with rglob("*") bounded by
max_entries. rglob yields entries in arbitrary order and counts every one, so a
model directory that also holds a large hidden subtree (.git/.cache/venv) could
exhaust the budget before reaching the real weights and falsely report no model,
hiding a valid Recommended-folder chip. Replace the generic-weights pass with a
bounded BFS that skips hidden directories so their entries can't starve the walk.
Adds a regression test (50-entry .git beside the weights, max_entries=10).
* Fix/adjust model selector handling for PR #6364
* Studio: address codex review on the staging/recommended-folder paths
- chat-page auto-load: selectModel only clears pendingSelection on success, so a
failed auto-load left the hidden stage (and its edited load knobs) behind.
Abandon the stage when it still matches the failed pick.
- model picker: count fine-tuned rows in the On Device empty check so a
fine-tuned-only tab no longer shows a false 'No models on device' message
above the Fine-tuned section.
- general settings: add the remembered per-model load settings key to PREFS_KEYS
so 'Reset all local preferences' actually clears it.
- recommended-folders: recognize PyTorch .bin weights (gated by the scanner's
weight-name prefixes) so a .bin-only model folder still earns a chip; add tests.
* Studio: name-gate .bin weight detection and complete selector preference reset
Follow-up to the codex review on the model_format/recommended-folder paths:
- _dir_model_format and _scan_models_dir treated any .bin (incl. tokenizer.bin)
as a non-GGUF weight, so a suffixless GGUF folder shipping a companion .bin was
misclassified as a plain checkpoint and routed through the wrong load path.
Factor the scanner's weight-name gating into shared _is_weight_bin /
_has_non_gguf_weights helpers and use them everywhere (also in
_dir_has_downloaded_model).
- PREFS_KEYS was missing the new 'Select model settings' keys (load on selection,
expand/show-all quantizations), so 'Reset all local preferences' left them set.
- On Device cached search dropped the active format filter while a query was
typed; keep matchesFormatFilter applied so the format dropdown stays consistent.
Adds tests for the tokenizer.bin vs weight-.bin classification.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: validate Ollama blobs, gate staged context, honor RAM budget on no-GPU hosts
- recommended-folders: only count an Ollama dir once its manifest resolves to an
on-disk model blob, so a failed/pruned pull no longer surfaces an empty chip
- GGUF variant click: only seed the staged contextLength for already-downloaded
picks, so choosing an undownloaded quant from a partially cached repo still
starts its download (the staging effect short-circuits on a known context)
- device fit: classify GGUF variants against the system-RAM budget on no-GPU /
unified-memory hosts instead of reporting everything as fits, and pass
systemRamGb to every variant expander regardless of gpu.available
* Studio: scope Hub search to Recommended, fix staged non-GGUF settings, keep local MLX on Mac
- model picker: only run the Hub search hooks on the Recommended section. On
Device / Connected render local data, so typing there no longer fires HF
requests or a spinner and the local/offline flow is preserved
- chat settings: when a pick is staged, decide the GGUF-only controls from the
staged model's type, not the currently loaded model's. A staged non-GGUF Hub
repo no longer inherits a loaded GGUF's context/KV/speculative controls
- On Device: keep local MLX builds in ./models selectable on Mac (chat-only ran
GGUF/MLX only, but the filter dropped MLX before the format toggle)

* 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.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* 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.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* 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.
* Fix MLX repair and health auth for PR #6494
* Fix macOS upstream prebuilt fallback for PR #6494
* Fix MLX stack validation for PR #6494
* Fix MLX self-heal validation for PR #6494
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* 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.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* 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.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* 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.

* Studio: fix llama.cpp update toast tag and reload hint
The post-update toast used the job's to_tag, which is the bare bNNNN build
number (same as installed_tag), so it showed e.g. "b9726" instead of the full
release tag. Use status.latest_tag (e.g. b9726-mix-<sha>) to match the tag the
banner already shows, falling back to to_tag and then a generic label.
Also drop "Reload your model to use it." when there is nothing to reload: only
append it when a local model is loaded, since external-provider models do not
use llama.cpp.

* Studio: fix Bypass Permissions menu freeze and show decimal GB for model sizes
Bypass Permissions freeze: the warning dialog lived inside the composer
"+"/More dropdown and kept the menu mounted via onSelect preventDefault,
so confirming or cancelling the dialog left both popovers frozen open.
Lift the dialog out of the menu into a store-driven
BypassPermissionsConfirmDialog mounted at a stable spot in the composer.
The menu item now closes normally on select and just toggles a new
bypassConfirmOpen store flag, so the popovers dismiss as expected.
Model search sizes: formatBytes divided bytes by 1024 but labelled the
result "GB", so unsloth/GLM-5.2-GGUF:UD-IQ1_S showed 201.8 GB where
Hugging Face reports 217 GB. Switch the search display to decimal
(base-1000) units to match what Hugging Face reports. The GPU-fit math
stays base-1024 since VRAM capacity is binary.
* Studio: address review feedback and add GLM-5.2 high/max/disabled thinking
Review feedback on the Bypass Permissions and size-format changes:
- Mount the Bypass Permissions warning dialog once at the chat-page root
instead of inside each Composer. It is driven by global store state, so
the per-composer mount meant Compare mode (multiple composers) rendered
duplicate dialogs and the shared-composer menu had none. A single root
mount fixes both.
- Defer opening the dialog past Radix's menu-close focus restoration with
setTimeout(0), so the dropdown does not steal focus back and break the
dialog's focus trap.
- Clamp the unit index in formatBytes so units[i] cannot go out of bounds
past TB (and to absorb log() float error at exact powers of 1000).
GLM-5.2 reasoning levels:
GLM-5.2's template gates thinking with enable_thinking and also reads a
reasoning_effort level ('high' or 'max'), so it needs high / max /
disabled rather than the binary toggle it got before (its style was
detected as enable_thinking, which made 'high' unreachable). Add a new
reasoning style 'enable_thinking_effort' that reuses the effort dropdown
but, unlike gpt-oss, can be fully disabled:
- detect_reasoning_flags classifies a template that has both
enable_thinking and reasoning_effort, extracting the discrete levels
from the quoted effort literals it branches on. Templates with only one
of the two (gpt-oss, Qwen3, DeepSeek, GLM-4.6) are unchanged.
- _request_reasoning_kwargs maps the new style to enable_thinking plus an
in-range reasoning_effort; disabling sends enable_thinking=false. The
gpt-oss reasoning_effort path is left untouched.
- The backend reports reasoning_effort_levels on the load/status response;
the frontend carries them through to the effort dropdown and sends
enable_thinking + reasoning_effort for this style.
Verified: backend reasoning kwargs render the real GLM-5.2 template to
"Reasoning Effort: High/Max" (thinking) and an empty <think></think>
(disabled); tsc, eslint, i18n parity and the production build all pass.

* Studio: address review feedback on reasoning effort and formatBytes
- chat-adapter localReasoningEffort: accept 'minimal' so a template that
branches on it (extracted into reasoning_effort_levels) is sent through
instead of being coerced to 'low' and then dropped by the backend.
- formatBytes: return '0 B' for non-finite / non-positive sizes (missing
metadata -> NaN, Infinity, negatives) and clamp the unit index lower
bound to 0, so sub-1-byte values can't produce a negative index.
* Studio: hybrid reasoning none gate and decimal GB in load progress
- _request_reasoning_kwargs: for enable_thinking_effort models, treat a
raw reasoning_effort='none' (OpenAI 'no reasoning' sentinel) as the
enable_thinking=false off gate, so a direct API caller can disable
thinking even without passing enable_thinking. The frontend already
sends enable_thinking=false; this only affects raw API callers.
- use-chat-model-runtime: the download / 'X of Y GB in memory' load
progress divided bytes by 1024**3 but labelled GB, so it disagreed with
the model picker and Hugging Face. Use decimal GB (1e9) to match.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: carry hybrid reasoning levels on all load paths and harden formatBytes
Review follow-ups on the enable_thinking_effort work:
- Every model-load path now copies reasoning_effort_levels and derives
supportsReasoningOff, via a shared reasoningCapsFromLoad() helper. The
shared/Compare composer load and the three chat-adapter auto-load paths
previously set only reasoningStyle, so a GLM-style hybrid model loaded
through Compare or first-chat auto-load fell back to the default
low|medium|high and lost its Max / Off controls.
- The local send path clamps the effort to the loaded model's advertised
levels (clampReasoningEffortToLevels) instead of a hard-coded list. A
stale "max" carried over from an external provider no longer reaches a
pure reasoning_effort (gpt-oss) model that only accepts none|low|medium|
high, where the backend would have dropped it.
- formatBytes divides iteratively instead of via Math.log, which has float
error at exact powers of 1000 (log(1e12)/log(1000) = 3.9999... would
label 1 TB as "1000 GB"). Keeps the non-finite/non-positive guard.
