cd982a121d docker: dedupe repeated rationale comments and parametrize the pip-shim tests
Comment-only consolidation: the sm_103/sm_121 + cu13 JIT story and the
xformers-aarch64 note were each told four times across docker/Dockerfile; keep
the header telling canonical and cross-reference it elsewhere (same for the
workflow's six retellings of the resolve-refs-once rationale and
Dockerfile.studio's NVRTC block). Comments that pointed at the removed dev
scripts now name the underlying command or artifact instead. Non-comment lines
of both Dockerfiles and the workflow are byte-identical.

unsloth_sync_notebooks.sh folds the three copies of the override -> PATH ->
sibling helper resolution into one resolve_helper(), behavior verified for all
four modes including graceful absence under set -u.

unsloth_pip_shim.py collapses an if/else whose branches were identical and
merges the structurally duplicate _parse_include/_parse_editable into one
_parse_flag_line. The test suite folds 35 near-duplicate tests into 8
parametrized groups with exact case-count parity (69 collected before and
after, 81 passing including the nb-pip-magic suite).

Cuts another 144 lines with zero behavior change outside the two refactors.

fix: single-pass GGUF export for directly convertible outtypes in save.py (#7090)
* Single-pass GGUF export for direct outtypes + parallel multi-quant

save_to_gguf defaulted first_conversion to model_dtype before the block
that picks the optimal base conversion, leaving that block dead since it
landed (#3356). Every default export (fast_quantized -> q8_0) therefore
ran two passes: convert HF -> 16-bit GGUF, then llama-quantize -> q8_0,
writing a 2x-size intermediate that the cleanup step deletes again.

- Route single-output exports whose type convert_hf_to_gguf.py emits
  directly (f32/f16/bf16/q8_0) through one conversion pass with no
  16-bit intermediate. Measured on Qwen2.5-0.5B-Instruct (8-core CPU):
  bytes written 1525 MB -> 531 MB (2.9x less), peak extra disk 994 MB
  -> 0, wall time neutral on local NVMe (14.8s vs 15.4s). The dequantized
  q8_0 tensors are bit-identical to the two-pass output (max diff 0 over
  all 290 tensors, same quant-type table). On disk-capped runtimes
  (Kaggle 20 GB, Colab) the removed intermediate is the difference
  between an export that fits and one that dies - see the Kaggle error
  text this file already carries. imatrix runs keep the two-pass route
  since only llama-quantize can apply one; explicit first_conversion is
  still honored.

- Run independent llama-quantize passes two at a time when several
  quant methods are requested (thread budget split between workers,
  outputs byte-identical, order preserved). Measured 1.38x wall-clock
  on q4_k_m+q5_k_m+q6_k. Sequential under UNSLOTH_ENABLE_LOGGING=1 to
  keep subprocess logs readable; kill switch
  UNSLOTH_PARALLEL_GGUF_QUANTS=0. Duplicate methods now quantize once.

* Guard parallel GGUF quant on Kaggle and make multi-quant failures atomic

Each llama-quantize pass loads the whole model into RAM, so running two at once on Kaggle can OOM a host that succeeded sequentially; skip the parallel path there. On a failed multi-quant export, stop launching queued passes and remove orphaned quant outputs so a failure leaves no partial GGUFs behind, keeping the 16-bit base for retry. Also accept 0/false/no/off/empty for UNSLOTH_PARALLEL_GGUF_QUANTS so a well-meant 'false' actually disables parallelism, and add tests/saving/test_gguf_single_pass_export.py to the CI saving bucket so the new tests run.

* Preserve pre-existing outputs for canceled quant passes on failure

The parallel cleanup unlinked every requested output name, so a failed rerun could delete a valid model.<METHOD>.gguf left by an earlier successful export for a method whose pass was canceled and never ran this session. Skip canceled futures and only remove outputs from passes that actually executed.

* Gate parallel GGUF quant on available memory and preserve prior outputs

Skip the two-worker path when RAM cannot hold two full-model quantizations at once (and on Colab as well as Kaggle), so a multi-quant export that fit sequentially no longer OOMs. On failure, remove only outputs this run newly created, tracked against a pre-launch snapshot, so a rerun into an existing _gguf directory never deletes a valid artifact from an earlier export.

47d66ecb53 docker: harden rollback, publish, shim, and view-cleanup paths
Ten verified fixes from a 12-reviewer audit of the image tooling, each
reproduced before fixing:

1. install_llama_prebuilt.py move_install_dir_aside: the EXDEV fallback
   copied straight into the rollback path, so a copy that died halfway
   (ENOSPC, I/O error) left a partial tree that activation recovery would
   later restore over the intact install while deleting the good copy.
   Copy to a temp sibling and publish with one atomic rename; dst.exists()
   is now a truthful complete-tree signal.

2. unsloth_run.py --out truncated the existing output before nbconvert
   ran, so a timeout, missing kernel, or failed cell irreversibly
   destroyed the previous result. The input copy and executed result are
   staged as temp files next to the destination and published with
   os.replace only on exit code 0.

3. unsloth_nb_view.py cleanup treated every symlink in the view as its
   own: user-created links (and an operator's view-root routing symlink)
   were deleted on every rebuild. Cleanup now removes only links that
   resolve into the notebooks tree it links from, and builds inside a
   view-root symlink's target instead of unlinking it.

4. unsloth_llama_update.sh: the unconditional EXIT trap deleted the .old
   backup even when it was the only remaining copy (signal between the two
   renames, or a failed swap whose restore also failed). The handler now
   restores the backup first when the install dir is missing and removes
   it only after the new tree is verifiably active; HUP/INT/TERM route
   through the same handler.

5. unsloth_pip_shim.py: transitive dependencies could replace the baked
   torch stack (reproduced with a wheel requiring torch==99.0). Every
   forwarded install now carries a constraints file pinning the installed
   protected set, turning the swap into ResolutionImpossible.

6. unsloth_pip_shim.py: ${UPPER} env references in requirements files were
   classified before pip expanded them, bypassing the protected-package
   filter; the shim now expands with pip's exact regex first.

7. unsloth_pip_shim.py: a failure writing the filtered requirements copy
   returned the ORIGINAL file, forwarding exactly the protected pins it
   had detected; it now fails closed.

8. docker-publish.yml: workflow_dispatch defaulted unsloth_ref to 'main'
   while the stable-tag gates require '', so UI-default manual runs could
   never advance :core/:latest/:studio; the default is now empty.

9. entrypoint.sh: the sm_103/sm_121 branch rewrote libnvrtc.so.12 to the
   CUDA-13 build but the ordinary-GPU branch never restored it, so a
   container moved to an older GPU kept the stale link; it is now reversed
   when it points exactly at the .cu13 target.

Rejected after verification (no code change): timeout=0 semantics are
documented at the site with no zero callers, TORCHINDUCTOR_COMPILE_THREADS
override is deliberate, fetchNews is a string enum per JupyterLab's schema,
:base tag appears in no in-tree doc, install-cell digest exclusion is the
module's stated contract, transformers ceiling semantics are documented,
and the cloudflared download mirrors the pre-existing Studio downloader
(Cloudflare publishes no checksum asset). The UNSLOTH_ALLOW_CPU import
crash lives in unsloth_zoo (compiler.py / loss_utils.py capability probes),
not in this diff; the image consumes the zoo fix automatically once merged
there.

Tests: shim suite extended to 63 (constraints, env expansion, fail-closed),
jit-selector suite to 14 (NVRTC reversal transitions), plus staged-publish
and ownership repros; wider studio install suite green except failures
reproduced at the unmodified head.

CI: retry transient HTTP timeouts in Studio smoke probes (#7052)
* CI: retry transient HTTP timeouts in Studio smoke probes

The post() helper in the Studio inference smoke workflows does a single
urlopen with a 240s timeout against the local Studio server. On shared
runners this sporadically hits TimeoutError while the server is stalled,
failing the whole job for a transport hiccup; the same flake has recurred
across unrelated PRs on Linux and Windows (JSON/images and tool-calling
jobs) and passes on rerun.

Retry the probe up to 3 times on transport-level failures only
(TimeoutError, ConnectionError, non-HTTP URLError), 15s apart. HTTP
status errors still surface immediately, so genuine server failures are
unaffected. post_sse() is left unchanged: it has a 600s budget and has
not flaked.

* CI: retry only short probes so worst case fits the job budget

Some json-images calls pass timeout=600; three attempts there could spend
30 minutes in one step and hit the job's timeout-minutes instead of failing
with the Python error. Retry (3 attempts) only when timeout <= 300s, which
covers the observed flaky 180-240s probes; longer probes keep the pre-PR
single attempt.

* CI: give long smoke probes one capped retry

Round two of bounding the retries: timeout>300s probes previously got a
single attempt, so a transient stall in the 600s JSON-mode probes still
failed on first occurrence. Give them one retry with the attempt timeout
capped at 300s. Worst cases stay inside timeout-minutes: 240s probes
12.5 min, one 600s probe 15.25 min, the Windows JSON job's two long
probes 30.5 min against its 35 minute budget.

scripts: refresh scan_packages allowlist baseline (#7032)
* scripts: refresh scan_packages allowlist baseline

Regenerate scripts/scan_packages_baseline.json against the current
resolved dependency set so the blocking pip scan-packages gate matches
what the scanner now finds. Refreshes evidence hashes for benign
findings whose code shifted lines (unsloth-zoo mlx loader, gguf/mlx
test /tmp fixtures) and adds two mainstream-library entries that were
newly surfaced (torch inductor codecache base64+subprocess compile
cache, torch testing common_utils socket import). Stale entries whose
matching code changed and no longer triggers are dropped.

All entries remain CRITICAL/HIGH findings manually judged benign;
matched on (package, file, check, evidence_hash).

* ci(security-audit): re-run scan when the allowlist baseline changes

The security-audit pull_request trigger listed the scanners but not
their allowlist baselines, so a baseline-only edit never re-ran the
scan that consumes it. A refreshed baseline could therefore merge
without CI confirming its evidence hashes match what the scanner finds.
Add scan_packages_baseline.json and scan_npm_packages_baseline.json to
the paths filter so baseline changes are validated on their own PR.

unsloth start: add --persist to keep and reopen agent sessions (#7014)
* unsloth start: add --resume to persist and reopen agent sessions

`unsloth start <agent>` launches a coding agent whose home is a throwaway
temp dir wiped on exit, so codex/openclaw/hermes/pi (which relocate their
whole home there) cannot resume a conversation after you quit. opencode and
claude keep their session data in a fixed user dir, so they already resume.

Add an opt-in --resume/--no-resume flag: it routes the launch to the stable
Unsloth agents dir (the same one --no-launch already uses) so the session
survives the exit, never touching the user's own ~/.<agent>. A bare --resume
also reopens the last conversation via the agent's native flag (codex
`resume --last`, opencode/claude/pi `--continue`). The default is unchanged:
a plain launch still uses a temp dir and persists nothing.

Add a dispatch-only `resume` job to the Local Agent Guides CI that drives the
real launch path and asserts the split: codex/pi are wiped without --resume
and persist with it, while opencode/claude persist either way.

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

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

* unsloth start: rename --resume to --persist

The session flag collided with agents' own resume flags. `unsloth start
claude --resume <id>` used to forward `--resume <id>` straight to Claude
(which keeps its history in ~/.claude regardless), so a boolean --resume on
unsloth start would have swallowed the session id and turned it into a stray
prompt. Name the persistence flag --persist instead, so every agent's native
resume flag (claude --resume <id>, codex resume, opencode --continue, ...)
still passes through untouched. Behavior is otherwise identical: --persist
keeps a launched agent's session under the Unsloth agents dir, and a bare
--persist reopens the last conversation.

Add a regression test that `--resume <id>` passes through verbatim, and in the
CI resume experiment skip the redundant second pass for opencode/claude (they
persist either way, and a second CPU turn only risks a timeout).

* unsloth start: correct --persist help and drop the buggy auto-resume

Reword the --persist help to be accurate: claude and opencode keep sessions in
the user's own stores and resume regardless, so --persist only stabilizes the
otherwise-ephemeral relocated home of codex/openclaw/hermes/pi. Drop the
bare-launch auto-append of native resume tokens: it errored on a first launch
with no prior session, and was inconsistent between launch and no-launch.
--persist now only keeps the session dir; resume via the agent's own command
(e.g. `unsloth start codex --persist resume`), which now finds it.

In the CI resume experiment, fail the pass when the launched turn exits
non-zero, so a write-then-error is not misread as PERSISTED.

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

* Restore floating monitor exit animation

* Harden Windows Studio smoke checks

* Keep API menu badge removed

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

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

* Reset chat UI session without a second browser context

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

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

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

* Drop stale localStorage auth tokens before re-login

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

version-compat CI: fake CPU training runs for SFT/GRPO/DPO (#6965)
* version-compat CI: fake CPU training runs for SFT/GRPO/DPO

Adds a runtime layer on top of the patch-run canary: actually runs
trainer.train() for a couple of steps on a CPU-only runner under the CUDA
spoof, wrapping a plain tiny HF model in the Unsloth-patched trainer. Exercises
the real train() loop (collation, generation, the injected
_get_per_token_logps_and_entropies, loss, backward, optimizer) so a TRL or
transformers change that breaks the loop at runtime -- not just the source
structure -- surfaces here. No GPU, no meaningful numerics.

Needs a chain of small CPU shims (eager torch.compile, dynamo suppress, cuda
tensor-alloc redirect to CPU, model.for_training/for_inference equivalents)
documented inline. Does not exercise Unsloth's Triton/GPU kernels (CPU can't).

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

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

* cpu fake-train: force adamw_torch + disable dynamo for CPU runner

On a real CPU-build torch runner (GitHub CI) two things bit that a CUDA-build
torch with GPUs hidden masked locally:

- The default optimizer is adamw_8bit (bitsandbytes), whose is_on_gpu() check
  dies on CPU tensors. Force optim=adamw_torch in all three configs.
- import unsloth reinstalls the real torch.compile over the eager passthrough,
  so the GRPO hot path (chunked_selective_log_softmax) actually compiles and
  inductor picks the spoofed CUDA device, crashing on device props
  (gcnArchName). Re-apply the eager passthrough after import and flip
  torch._dynamo.config.disable so every @torch.compile runs eager at call time.

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

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

* cpu fake-train: write checkpoints under pytest tmp_path

Use pytest's tmp_path for each trainer's output_dir instead of a hardcoded
relative temp/ci_* path, so a local pytest run does not leave untracked dirs in
the repo tree and the tests are CWD-independent.

* version-compat CI: disable dynamo at process level for the fake-run job

Set TORCHDYNAMO_DISABLE / TORCH_COMPILE_DISABLE in the fake-run step env so
dynamo/inductor is off before conftest.py's early import unsloth, not only via
the per-test runtime shim. Defense in depth on the GPU-less runner: the GRPO
hot path never compiles regardless of when its functions were decorated.

(GRPO) Fix PEFT replacement for TRL >= 1.7.0, add missing compute_aux_loss for TRL >= 1.7.0 (#6904)
* Fix PEFT replacement for TRL >= 1.7.0, add missing compute_aux_loss for TRL 1.7.0

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

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

* Fix GRPO for TRL >= 1.7.0: PEFT ref-adapter removal and return arity

rl.py: for trl >= 1.7.0, scope the PEFT removal regex to the ref-adapter
block only by anchoring the end on ref_param.data.copy_(param.data), so it
no longer also deletes the following gradient-checkpointing
enable_input_require_grads() block. Neutralize TRL 1.7.0's
`if _is_quantized_model:` bf16 cast the same way the existing
is_loaded_in_4bit cast is handled.

rl_replacements.py: initialize _extra_moe_kwargs before use (it was
referenced before assignment whenever compute_aux_loss was passed) and only
request output_router_logits when the aux loss is actually wanted.

rl_replacements.py: _get_per_token_logps_and_entropies now returns a 3-tuple
(logps, entropies, aux_loss) for trl >= 1.7.0 and a 2-tuple for older TRL,
matching how every TRL call site unpacks the result. Without this, TRL 1.7.x
_generate_and_score_completions unpacks 3 values from a 2-tuple and raises
"not enough values to unpack (expected 3, got 2)".

* Return zero aux_loss placeholder and drop inference-mode aux collection

* GRPO TRL >= 1.7.0: reject router aux-loss opt-in at init; drop zero aux placeholder

Unsloth's optimized GRPO forward cannot compute the MoE router auxiliary loss.
Previously an explicit opt-in (router_aux_loss_coef > 0) returned a fabricated
zero, silently training without the requested load-balancing penalty. Now reject
it at trainer init with a clear NotImplementedError, and return None (not zero)
for the aux slot of TRL's 3-tuple. Default stays off (coef 0), so the common
path is unaffected.

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

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

* GRPO hidden-states fallback: free ModelOutput before chunked log-softmax

The old/ref logprob fallback binds the full ModelOutput (which holds every
layer's hidden_states when output_hidden_states=True) and kept it alive across
chunked_hidden_states_selective_log_softmax, an avoidable OOM on large models.
Extract logits then del outputs in both the text and VLM branches.

* Version-compat CI: proactively catch TRL GRPO breakage

The existing TRL canary is a static symbol/source grep: it verifies symbols
exist but is blind to structural changes (TRL 1.7.0's 2->3-tuple per-token-logps
return arity and restructured PEFT ref-adapter block, which the fix in this PR
addresses, both slipped past it because the methods still existed).

Two additions:
- test_trl_grpo_pinned_symbols.py: extend TRL_TAGS to 1.5/1.6/1.7 and pin the
  exact source-string contracts the rl.py / rl_replacements.py transforms depend
  on for TRL >= 1.7.0 (PEFT elif ref-adapter block + enable_input_require_grads
  survival, if _is_quantized_model, aux_loss_enabled anchor, compute_aux_loss
  arity). A future TRL change fails on main a few days before the PyPI release.
- test_trl_grpo_fake_run.py + a version-compat-ci job: fake-CUDA run that drives
  the real GRPO/SFT/DPO source-transform patchers against latest + main TRL on a
  CPU-only runner (no training) and asserts the generated Unsloth trainer still
  satisfies the transform contracts. Catches behavioral regressions the grep
  cannot see.

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

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

* fake-run test: use a normal Version import for the aux gate

* version-compat CI: fix fake-run job gate + torch-absent collection

- Drop the invalid job-level matrix if (matrix is not available in
  jobs.<id>.if -> 'Unrecognized named-value: matrix' fails the whole
  workflow). Use a single job that runs vs TRL latest always and re-runs
  vs TRL main only on schedule/dispatch via a step-level github.event_name
  guard. Validated with actionlint.
- Module-level skip the fake-run test when torch is absent so
  daily-fresh-fetch (pytest-only, collects tests/version_compat/) does not
  crash on the top-level spoof import.

* fake-run test: do not skip on import failure

unsloth/trl are installed in the grpo-fake-run job, so a failing import is the
import-time drift this canary must catch. Keep only the not-installed find_spec
skips; let a real import error fail the test.

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

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

* GRPO arity gate: regex downgrade + fail loud + CI coverage

The TRL < 1.7.0 per-token-logps return downgrade was an exact-string replace
anchored on the full return line incl. its comment, so a reformat (e.g.
pre-commit) could silently no-op it and ship a 3-tuple to older TRL. Switch to
a regex tolerant of comment/whitespace drift, and raise if the anchor stops
matching (re.subn count != 1) instead of failing silently. Add a monkeypatched
trl_version unit test asserting both arities, since CI only installs TRL >= 1.7.0
and never exercised the downgrade otherwise.

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

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

* fake-run: give SFT/DPO a real contract, not just ast-parse

The SFT/DPO fake patch runs only checked the generated trainer parses. Also
assert the shared QLoRA _is_quantized_model bf16 cast is neutralized (TRL 1.7's
spelling, present in both sft_trainer and dpo_trainer), so a structural TRL
change to that block is caught for SFT/DPO too, not just GRPO.

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

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

* GRPO PEFT ref-adapter removal: lower gate to the TRL 1.4.0 floor

The elif is_peft_model(model) and args.beta != 0.0: ref-adapter block was
introduced in TRL 1.4.0 and is unchanged through 1.7.x, but the removal was
gated at >= 1.7.0, so for 1.4 <= TRL < 1.7 the transform fell through to the
0.27 branch (which matches the older if is_peft_available()... form) and
silently no-oped: a PEFT + beta != 0 GRPO run then computed the KL reference
from the copied ref adapter instead of the base model. Lower the gate to
1.4.0 and keep the 1.7.0-only router aux-loss fail-fast nested. Widen the
pinned-symbol contract test to run from 1.4.0 so the covered versions are
actually exercised.

251e3edf93 docker: address review round 3 (requirement-file shim edges + device-gate cu13 JIT tools)
unsloth_pip_shim.py: close three more ways a protected package slipped past
_KEEP. An editable line (-e/--editable <target>) inside a -r requirements file
is a real install target, so a protected editable there is now classified and
dropped like the command-line case (new _parse_editable). pip/uv accept the
attached short forms -rreqs.txt / -cconstraints.txt / -epath / -Pname as one
token; these were falling through as opaque options (so an attached -r-only cell
no-op'd and an attached -c/-e/-P value bypassed _KEEP), so the 2-char flag is now
split from its value and routed through the separated-form handling. And a nested
-c constraint inside a -r file no longer records its transformers pin as an
install request (a constraint is not a request; mirrors the top-level -c path).

entrypoint.sh / Dockerfile: gate the CUDA 13 ptxas + NVRTC to sm_103 / sm_121 at
runtime instead of a global build-time default. A cu13 cubin needs a >= 580
driver to LOAD even when it targets an older arch (CUDA has forward, not
backward, cross-major driver compatibility), but the image supports Turing..
sm_120 on a 570+ driver, so the previous global TRITON_PTXAS_PATH ENV + cu13
NVRTC symlink would break ordinary Triton/NVRTC JIT on 570-579 driver hosts. The
build still bakes cu13 (saving the cu12.8 NVRTC as .cu128.orig); a new
select_cuda_jit_tools() in the entrypoint reads the device compute_cap and only
activates cu13 for sm_103/sm_121 (which ship >= 580 drivers), otherwise leaving
Triton on its bundled cu12.8 ptxas and restoring the cu12.8 NVRTC in both the
base and Studio venvs. The base ENTRYPOINT runs for the Studio image too.

Adds 9 pip-shim regression tests and tests/sh/test_select_cuda_jit_tools.sh
(7 device-gating cases); registers the latter in CI and tests/run_all.sh.

d4dc8b6391 docker: address review round 2 (CI ref freeze, Studio NVRTC amd64, pip-shim edges)
docker-publish.yml: freeze the requested unsloth ref to one sha in the prepare
job before the matrix fans out. UNSLOTH_REF / UNSLOTH_STUDIO_REF were raw
expressions re-evaluated per base arch leg and in the Studio build, so a mutable
branch (the workflow_dispatch default unsloth_ref=main) advancing during the run
could bake different unsloth commits under one manifest. Resolve once (same
precedence: dispatch input, else pushed tag, else triggering sha, else main;
ls-remote a branch/tag to a sha, mirroring the zoo/notebooks steps) and read
needs.prepare.outputs.unsloth_ref everywhere.

Dockerfile.studio: run the Studio venv NVRTC cu13 swap on both arches, not arm64
only. amd64 sm_103 (B300/GB300) needs cu13 NVRTC just as arm64 sm_121 does, and
the CUDA dedup never touches cuda_nvrtc, so an amd64 Studio venv would otherwise
keep its bundled cu12.8 libnvrtc and fail NVRTC/jiterator JIT on compute_103. The
base cu13 layer installs cuda-nvrtc-13-0 on both arches, so the target .so.13
exists here regardless of TARGETARCH.

unsloth_pip_shim.py: close three ways a protected package slipped past _KEEP.
Treat -e/--editable as a value-taking flag paired with its target and drop both
when the target is protected (was leaving a dangling -e that failed the cell);
filter -P/--upgrade-package values through _KEEP (a named baked package could be
refreshed while installing another target); and parse the PEP 427 distribution
name out of a wheel URL/path so a bare `pip install https://.../torch-...whl`
drops instead of reinstalling the baked torch. Non-protected editables, upgrade
selectors, and wheels are unchanged. Adds tests/python/test_unsloth_pip_shim.py
(18 regression tests, exec captured via a patched os.execv).

docker: Colab-grade JupyterLab and Studio UX for the Unsloth image (#6681)
* docker: Colab-grade JupyterLab and Studio UX for the Blackwell image

Stacks a Colab-like JupyterLab and Studio experience on top of the
existing Blackwell image. Additive only: the training stack, CUDA/torch
pinning, and the Studio/JupyterLab/sshd service trio are unchanged.

JupyterLab labextension (prebuilt in a throwaway builder stage, so the
runtime image stays Node-free):
  - Unsloth Dark (Monokai) theme, adaptive light/dark by system preference
  - Colab-style ArrowDown/Up cell navigation
  - top-bar Unsloth logo (stock Jupyter logo disabled and locked)
  - #@title lines render as collapsible Heading-2 form bars
  - Ctrl+A in a cell output selects only that output, not the whole
    notebook (the old behaviour ran notebook:select-all and was laggy)
  - right activity bar hidden by default
  - overrides.json: per-cell run button without auto-advance, labeled
    Restart and Run All, windowing off so collapsing an output does not
    snap to the cell top, news/update prompts suppressed

Studio and login branding: Unsloth favicon, page logo, and a dark
Unsloth login page that rotates through the curated Studio sloth
stickers (fail-soft to the logo).

Notebook organization and Colab compatibility (base image):
  - categorized folder view built from relative symlinks mirroring the
    README sections, rebuilt each boot; real .ipynb files never moved,
    and the symlink tree is invisible to the sync state machine
  - AMD-* notebooks shown only on an AMD/HIP host (autodetected)
  - Docker-only strip of the Colab "Run all on Colab" intro sentence
    from unedited notebooks (upstream notebooks unchanged)
  - hoist %%capture above a leading #@title form so the cell runs
  - the per-cell transformers-sidecar log is silent unless
    UNSLOTH_ENABLE_LOGGING=1

Dependency pinning and naming: the curated notebook extras are pinned to
their resolved versions for reproducible rebuilds; decord is split into
its own fail-soft install (no aarch64 wheel). The lean base image is
renamed from :base to :core.

Adds tests/validate_studio_features.py, a static self-test for the
labextension plugins, overrides keys, and branding wiring.

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

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

* docker: address review feedback on the JupyterLab/Studio UX

- unsloth_nb_view.py: rebuilding the categorized view no longer deletes
  user files. The view is also JupyterLab's landing dir, so a user may
  save real notebooks there; _clear_view now unlinks only the symlinks we
  own and removes only folders that end up empty, leaving regular files
  in place. It also tests islink before isdir, so a view that is itself a
  symlink to a directory is unlinked instead of being walked into (which
  would have wiped the symlink target).

- studio_launch.sh: derive the landing URL and preferred_dir from
  UNSLOTH_NOTEBOOKS_VIEW_DIR / UNSLOTH_SKIP_NOTEBOOK_VIEW, the same env
  the sync script uses, instead of hard-coding /workspace/Unsloth
  Notebooks. A relocated or disabled view no longer opens JupyterLab on a
  missing folder; it falls back to the default /lab over /workspace.

- Dockerfile.studio: the labext-builder stage now installs Node 20 from
  NodeSource. Ubuntu 24.04's distro nodejs is 18, below JupyterLab 4.6's
  declared Node >=20 engine. Node stays confined to the throwaway builder
  stage, so the runtime image is unchanged.

- .dockerignore: explicitly allowlist jupyter/install_sloth_stickers.py
  alongside its sibling jupyter assets, rather than relying on the
  directory re-inclusion.

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

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

* docker: publish lean image as :core and full image as :studio

Complete the base->core (and "studio as studio") tag rename so the publish
workflow matches the user-facing helpers and the Dockerfile.studio header.

- The lean training image now publishes as :core (core-<tag>, core-nightly,
  core-sha-*); run.sh / docker_confirm.* already told users to pull :core, but
  docker-publish.yml still tagged it :base, so that pull would have 404'd. The
  per-arch digest artifacts are renamed to match.
- The full Studio image keeps :latest and gains a stable :studio alias, matching
  the Dockerfile.studio header.

Both the merge and post-publish smoke-test metadata blocks are updated together.
Internal "base image" wording (the layer Studio builds FROM) is left as-is.

* docker: address second-round review feedback on the JupyterLab/Studio UX

- studio_launch.sh: also gate the categorized-view landing URL on
  UNSLOTH_SKIP_NOTEBOOK_SYNC (the entrypoint skips building the view entirely in
  that mode), not just UNSLOTH_SKIP_NOTEBOOK_VIEW, so a no-sync container does not
  land on a missing folder.

- Dockerfile.studio: scope the sticker-install "|| echo" fallback to only the
  sticker step via a { ...; } group. It was attached to the whole branding &&
  chain, so a failure in a REQUIRED step (JS resolve, favicon/logo/login copy)
  was swallowed and the build continued with broken branding.

- unsloth_nb_view.py: when creating the categorized symlinks, only replace our
  own stale symlinks; if a real user file already occupies that name, keep it and
  skip the link instead of os.remove-ing it.

- overrides.json: drop doNotDisturbMode (it silenced ALL JupyterLab toasts,
  including kernel-restart / connection-drop feedback). The news/update prompts
  are already off via fetchNews / checkForUpdates.

- Dockerfile: keep decord mandatory on amd64 (fail the build on a missing or
  incompatible wheel) and only fail-soft on arm64/other arches that have no wheel.

- cellNav.ts: do not hijack ArrowUp/Down when focus is in an interactive output
  widget / form control, or while a completion popup is open, so ipywidgets
  controls and autocomplete at cell boundaries keep working.

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

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

* docker: keep Studio branding RUN free of comments inside the line continuation

Move the sloth-sticker fail-soft explanation above the RUN so no comment line
sits between backslash-continued commands. BuildKit strips such comments, but
keeping the RUN body a plain && chain removes the ambiguity for non-BuildKit
builders and static linters. The { ...; } fail-soft scoping is unchanged.

* docker: AGPLv3 attribution + integrity guard for the Studio/JupyterLab image

Make it obvious the image is built by Unsloth and hard to white-label out with a
shallow find-and-replace, and surface the AGPLv3 license + copyright in the UI.

Visible attribution (labextension):
- Help > "About Unsloth Docker Studio" dialog (about.ts): Unsloth logo, the
  AGPLv3 notice, "Copyright 2026-Present the Unsloth team", and source/website/
  license links. Added to the Help menu and the command palette.
- The JupyterLab loading splash is replaced with a spinning Unsloth logo
  (splash.ts, provides ISplashScreen; honors prefers-reduced-motion). The stock
  @jupyterlab/apputils-extension:splash is disabled+locked at build time, like
  the stock logo.
- AGPLv3 footer (license + copyright + links) on the branded login page.
- Labextension relicensed AGPL-3.0-only; SPDX headers on every source file.

Anti-tamper (no encoded/obfuscated strings -- plain readable text only; the one
data URI is the logo image):
- A canonical, plain-text attribution set lives in unsloth_branding.py with a
  TypeScript mirror (branding.ts) bundled verbatim into the labextension, so the
  phrase, copyright, links and plugin ids are spread across independent layers.
- unsloth_branding.py verifies all of these across the installed files (AGPLv3
  text, login footer, theme, labextension package + built bundle strings, logo,
  favicon) and fails loudly if any are missing. It runs at three layers:
  build time (fails the image build), the whole-container launcher
  (studio_launch.sh refuses to start), and as a jupyter_server extension
  (refuses to serve JupyterLab).
- tests/studio/test_branding_guard.py: positive + per-marker negative coverage,
  plus a check that no base64/decoder obfuscation crept into the attribution.

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

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

* docker: address #6681 review round 2 (colab magics, output select, branding guard)

- unsloth_colab_compat.py: only hoist a leading `%%` cell magic above the Colab
  `#@title` form for magics whose body runs as code (capture/time/bash/python/
  ...). Content magics (%%writefile, %%html, %%latex, ...) are left untouched so
  the form comment is never injected into the written file / rendered output.
- outputSelect.ts: stop trusting the text selection anchor to decide ownership
  of Ctrl/Cmd+A. A stale selection inside an output survives a click onto a
  command-mode cell or the file browser, which made select-all keep re-selecting
  the old output. Gate on the keystroke target or the last pointer-down (reset to
  null on any click outside an output) instead.
- unsloth_branding.py: also reject page_config.json that disables the Unsloth
  labextension or any of its plugin ids via disabledExtensions (dict or list
  form); that leaves the bundle on disk so the prior checks passed while the
  logo/About/splash attribution was stripped at load. Lock unsloth-jupyterlab in
  Dockerfile.studio as well (defense in depth), and add guard tests.

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

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

* labext: pin JupyterLab extension deps; confirm.ps1 /login probe

Pin the unsloth-jupyterlab npm deps to exact versions matching the baked
jupyterlab==4.6.0 (builder stays 4.5.9, its newest release) instead of floating
^/~ ranges, so the same commit always builds the same labextension bundle.
Also probe JupyterLab /login (not /api, which 403s behind a password hash) in
the Windows confirmation script.

* docker: categorize AMD/domain notebooks and wire the feature validation into CI

unsloth_nb_view.parse_readme only reset the folder section on level-3
(###) headings. The notebooks README carries level-1 domain headers
(# AMD Notebooks, # Kaggle Notebooks) with their own nb/*.ipynb link
tables and no intervening ###, so those notebooks were mis-filed under
the previous stale section (all 148 AMD notebooks landed in Other
Notebooks on an --amd build). Reset on any heading level and strip a
leading emoji/symbol run so the domain notebooks get their own clean
folder.

Also run tests/validate_studio_features.py explicitly in the repo CPU
job. It is named validate_* (not test_*) so pytest never collected it,
which meant a regression in the notebook view, Colab compat, strip,
JupyterLab defaults or login branding failed CI only when run by hand.

* labext: use caret ranges so jlpm dedups JupyterLab/Lumino singletons

The exact pins introduced earlier (@jupyterlab/* 4.6.0, @lumino/widgets
2.8.0, @jupyterlab/builder 4.5.9) break the Dockerfile.studio
labext-builder stage. Exact-pinning the framework packages defeats
jlpm's (yarn classic) hoisting: transitive @jupyterlab deps request
caret ranges that resolve to newer patch releases (e.g. @jupyterlab/
notebook pulls @jupyterlab/cells ^4.6.0 -> a newer patch), so jlpm
installs a second nested copy alongside the exact top-level one. Two
copies of @jupyterlab/cells and @lumino/widgets in the tree produce
TS2345 "not assignable" errors (protected-member/identity mismatch)
and the build fails.

Caret ranges let jlpm collapse every @jupyterlab and @lumino package
to a single hoisted copy, which is required for a JupyterLab prebuilt
(federated) extension: at runtime those packages are shared singletons
provided by the host JupyterLab, so the build-time versions only need
to type-check against one consistent tree, not match an exact runtime
patch. This is the version set the published image was built and
validated with end to end.

Verified by building the labext in isolation against the base image
(Node 20 + bundled jlpm): caret ranges build clean (webpack compiled
successfully); the exact pins fail with the duplicate-package TS
errors.

* ci(studio-backend): trigger on docker/** so the JupyterLab feature validation guards docker-only changes

The 'Docker JupyterLab/notebook feature validation' step runs
tests/validate_studio_features.py, which checks docker/jupyter (the
labextension, overrides.json, login branding) and the docker notebook
helpers. The pull_request paths filter listed studio/unsloth/tests but
not docker/**, so a PR that only touches docker/ would skip that step
and a regression in those files could pass CI. Add docker/** so the
validation runs whenever the files it checks change.

* jupyter: center the login card and place the attribution below it

#site was a flex container using the default row direction with two children
(the login card and the AGPLv3 attribution), so they rendered side by side:
the card sat left of centre and the attribution floated up to the top-right.
Stack them in a column so the card is horizontally centred and the attribution
sits below it as a footer, matching the intended single-column layout.

* jupyter: refresh Studio attribution, About dialog and loading splash

- Attribution now reads 'Built by the Unsloth team' with a single Apache 2.0 /
  AGPLv3 license link (to the repo license section) on the login page and in the
  About dialog, replacing the plain 'Built by Unsloth. Licensed under the GNU
  AGPLv3.' line. The integrity guard, its canonical PHRASE and the branding tests
  are updated to match.
- About dialog: left-align the link rows so the labels line up instead of each
  row centering independently; add an 'Unsloth Reference' link to the docs, and a
  Licenses section listing Unsloth Studio (AGPLv3) and Unsloth Core (Apache 2.0)
  alongside the full license link.
- Loading splash now reads 'Loading Unsloth Docker' instead of the attribution
  label, via a dedicated SPLASH_LABEL constant.

* docker: document the branding attribution as an AGPLv3 Section 7 notice

Add docker/NOTICE and docker/jupyter/BRANDING.md so the Unsloth attribution that
unsloth_branding.py enforces is also a written license condition, not only a
build check. docker/NOTICE designates the attribution (the "Built by the Unsloth
team" label, the copyright line, the license notice, the logo and theme, and the
Help > About links) as required Appropriate Legal Notices under AGPLv3 Section
7(b), referencing /studio/LICENSE.AGPL-3.0 and /LICENSE. BRANDING.md is a
human-readable note next to the guard describing what must stay, where it lives
and how it is enforced.

* ci(studio-backend): restore docker/** trigger path

The docker/** pull_request path added in b558bc7d was dropped by a later
rebase, so the "Docker JupyterLab/notebook feature validation" step (which runs
tests/validate_studio_features.py against docker/jupyter branding and notebook
helpers) no longer ran on PRs that only touch docker/. Re-add docker/** so a
docker-only change is validated on the PR rather than only after merge to main.

326f57ea71 docker-publish: freeze the unsloth-zoo ref to a concrete sha before fan-out
The zoo_ref prepare step emitted the bare branch name (main) on the normal
push/schedule path, and both arch matrix legs plus the Studio build pass that
to pip install unsloth-zoo @ git+...@REF. If unsloth-zoo advanced mid-build a
single multi-arch tag could bake different zoo code across architectures or
between the base and Studio venvs. Resolve a branch/tag to its current sha via
ls-remote here (mirroring the notebooks step), so the whole matrix pins one
immutable commit. A 40-char sha input stays frozen; a lookup miss falls back to
the bare ref so the build can still fetch by name.

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

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

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

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

Export page overhaul on top of the formats dropdown:

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

* 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

* 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

* 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.

CLI: Rename unsloth connect to unsloth start (#6613)
* replaced connect with start

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

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

* fix

* Studio: build the coding-agent command from the selected server

The API keys panel showed a hardcoded `unsloth start claude`. `unsloth start`
defaults to 127.0.0.1:8888 and only mints a key for a loopback server, so a
non-default port or a tunnel/remote base would target the wrong server or fail
to mint. Build the command from the panel base/key (and emit a key for
non-loopback), matching the other snippets in the panel.

* CLI: keep `unsloth connect` as a hidden alias for `unsloth start`

Avoids breaking existing scripts and docs that still call `unsloth connect`.

* Tests: stub _unstarted_cleanup in same-task disconnect test

The test builds _SameTaskStreamingResponse via __new__, so set the attribute
that __call__ now reads.

* Match coding-agent command loopback check to the CLI 127.0.0.0/8 rule (#6613)

* Keep unsloth_cli.commands.connect importable as a deprecated shim (#6613)

* Format the new coding-agents panel strings and import per biome (#6613)

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

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

* Drop the unsloth connect alias and shim; unsloth start is the only command (#6613)

* Route unsloth connect to unsloth start as a hidden backward-compatible alias (#6613)

* Forward unsloth run model-load flags to unsloth start (gguf-variant, context-length, load-in-4bit, tensor-parallel) (#6613)

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

* Session-scope coding agent config in unsloth start

Configure each agent for the current session instead of writing the Studio endpoint, key, and default model into the user's own config. Codex, OpenCode, OpenClaw, and Hermes get a private config relocated through their config-path env vars (CODEX_HOME, OPENCODE_CONFIG overlay, OPENCLAW_CONFIG_PATH plus OPENCLAW_STATE_DIR, HERMES_HOME). Claude Code suppresses the attribution header for the session via the CLAUDE_CODE_ATTRIBUTION_HEADER env var plus a --settings overlay, with no ~/.claude write. --launch uses an ephemeral temp dir removed after the agent exits; --no-launch uses a stable Unsloth-owned dir and prints the matching export lines.

* Read relocated agent session config in Local Agent Guides CI

The contract crosscheck and the openclaw/hermes patch helpers now read each agent's config from the relocated path printed by unsloth start --no-launch (CODEX_HOME, OPENCODE_CONFIG, OPENCLAW_CONFIG_PATH, HERMES_HOME) instead of fixed home paths. The Claude attribution A/B toggles the header for the session only (shipped-config HIT vs vanilla MISS) instead of editing ~/.claude/settings.json.

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

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

* Skip the POSIX-only --no-launch parser test on Windows

test_no_launch_output_is_parseable mirrors the #6547 bash CI parser, which greps export/unset lines and only runs on Linux/macOS runners. On Windows --no-launch prints PowerShell ($env: / Remove-Item), so the export-line assertion does not apply there. Cross-OS staging CI surfaced this.

* Size Claude Code's auto-compact window to the loaded model's context

Claude Code auto-compacts against its native (~600k token) window, so against a smaller local model it overflows the server's context (silent truncation) long before it compacts. Set CLAUDE_CODE_AUTO_COMPACT_WINDOW to the loaded model's real context length (the value codex/openclaw already get via model_context_window / contextWindow). Omitted when the model reports no context length.

* Pin OpenCode/Hermes context window and set 90% compaction across agents

Feed every agent the server-determined sequence length (the value /v1/models reports from runtime_context_length) and a ~90% compaction threshold. OpenCode: a custom-provider model with no limit defaults to context 0, which silently disables auto-compaction, so set limit.context/output and scale the compaction buffer to 10% of the window. Hermes: pin model.context_length (it otherwise falls back to a 256k default when the server's /v1/models omits the field) and set compression.threshold 0.9. Claude: add CLAUDE_AUTOCOMPACT_PCT_OVERRIDE=90 alongside the window. Codex (model_context_window) and OpenClaw (contextWindow) already carried the window and auto-manage off it.

* Add `unsloth start pi` recipe

Pi was the only agent without a built-in recipe, so the agent-guides CI
hand-wrote ~/.pi/agent/models.json. Add a first-class `pi` command mirroring
the others:

- write_pi_config writes the session-scoped OpenAI-compatible provider config
  (key in the config, like openclaw/opencode).
- pi() launches `pi --provider unsloth --model <id>` (Pi defaults to the google
  provider, so the provider/model are pinned on the command line) with HOME
  relocated for the session. Pi has no config-dir env var and resolves ~/.pi off
  $HOME, so HOME-scoping keeps the user's ~/.pi untouched.

Migrate the agent-guides CI off the hand-written config onto the
`unsloth start pi --no-launch` path (connection + file-edit), with a crosscheck
for the provider api, so the documented recipe is exercised.

* Harden unsloth start for Windows and WSL agent launches

Address the Codex review on PR 6613:
- write_pi_config now pins the loaded contextWindow and a sane maxTokens so Pi
  compacts instead of overflowing a small Studio context (it otherwise assumes
  its 128000 default), matching the other agents.
- pi() sets USERPROFILE (and HOMEDRIVE/HOMEPATH when present) alongside HOME on
  native Windows, where Node resolves ~/.pi via USERPROFILE rather than HOME, so
  the session no longer reads or writes the user's real ~/.pi.
- The WSLENV bridge flags path-valued vars with /p so a Windows npm shim under
  /mnt receives translated paths, while scalar vars (the numeric context window)
  pass through untranslated. WSLENV is deduped on the bare name.
- _print_env prints the launch command with PowerShell-safe quoting so the inline
  --settings JSON survives copy-paste on native Windows --no-launch.

Add tests for the WSLENV path flagging, PowerShell quoting, the Pi context
window, and the Pi USERPROFILE relocation.

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

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

* Set CLAUDE_CODE_NO_FLICKER for the Claude session

A local server streams in bursts, so Claude Code's full-screen TUI redraw
flickers between tokens. Disable it for the session via CLAUDE_CODE_NO_FLICKER,
alongside the other CLAUDE_CODE_* session env knobs.

* Add a normalized --yolo flag routed to each agent's auto-approve mode

It is easy to forget which agent spells "run tools without prompting" which way,
so `unsloth start` now accepts all three spellings as one option (--yolo,
--dangerously-skip-permissions, --dangerously-bypass-approvals-and-sandbox) and
routes to the agent's own mechanism:

- claude:   --dangerously-skip-permissions
- codex:    --dangerously-bypass-approvals-and-sandbox
- hermes:   --yolo
- pi:       --approve (Pi's only approval gate is project trust)
- opencode: a permission allow block in opencode.json (no CLI flag exists)
- openclaw: tools.exec security=full / ask=off / host=gateway (no CLI flag exists)

Because the option is parsed by `unsloth start`, the "wrong" spelling for an
agent still routes correctly instead of leaking through to the agent and erroring.
IS_SANDBOX is deliberately left unset for Claude so its root/sandbox safety gate
still applies. Adds routing, cross-routing, and per-config tests.

* Fix review findings: IPv6 loopback command, pi USERPROFILE under WSL, yolo guard

From a 10-reviewer pass over the PR:

- studio/frontend agent-command.ts: normalize bracketed IPv6 hosts. URL.hostname
  returns "[::1]" for http://[::1]:8888, which never matched the "::1" loopback
  checks, so the copied command embedded the placeholder API key for a local IPv6
  server instead of the bare auto-minting command. Now [::1] is treated as loopback
  like the CLI's is_loopback_url, so the command matches the CLI contract.

- pi(): also relocate USERPROFILE (and HOMEDRIVE/HOMEPATH) when running under WSL
  against a /mnt Windows shim, not just on native Windows. Windows Node resolves
  ~/.pi via USERPROFILE, and the WSLENV bridge translates the path, so pi no longer
  falls back to the user's real ~/.pi in that case.

- _yolo_command_flags: use .get so a config-based agent (or a typo) yields no flag
  instead of a latent KeyError.

Adds tests for the WSL pi USERPROFILE relocation, the yolo unmapped-agent guard,
and that opencode/openclaw --yolo stays config-only (no argv flag).

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

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

* Fix round-2 review findings: WSLENV /p upgrade, agent help text

- _merge_wslenv now upgrades a user's pre-existing unflagged WSLENV entry (e.g. a
  bare HOME or USERPROFILE) to the path-translated form (HOME/p) instead of leaving
  it as-is, so a Windows agent shim under WSL receives the translated session path
  rather than the raw Linux path.
- Generalize the `unsloth start` registration help to list all six agents (was only
  "Claude Code, Codex").

Adds a test for the WSLENV unflagged-entry upgrade.

* Fix round-3 review findings: complete openclaw --yolo, refresh stale copy

- openclaw --yolo now also writes the host approvals file (exec-approvals.json with
  defaults security=full / ask=off / askFallback=full) alongside the tools.exec
  config. OpenClaw gates tool execution on both layers (the stricter wins), so the
  config alone could still leave it prompting or denying. Mirrors `openclaw
  exec-policy preset yolo`. ask=off means nothing is ever prompted, so the runtime
  socket block is unnecessary.
- Studio API panel copy: clarify that a local server auto-mints the key while a
  remote one embeds it in the command, and add pi to the swap hint.
- Local Agent Guides CI: drop the stale "pi has no start.py recipe" note now that
  all six agents are driven via `unsloth start <agent> --no-launch`.

Adds the openclaw approvals-file assertions and a no-yolo openclaw test.

* start: parse claude --version with a regex so a format change does not drop optimization flags

* start: offer to install a missing agent (prompt then run its install command)

* start: auto-start a Studio server for --model when none is running, and stop it on exit

* inference: surface an actionable message when llama-server cannot compile a tool grammar

* start: split --model org/repo:variant so a running session is not evicted

`unsloth start <agent> --model org/repo:QUANT` failed against an already-running
Studio server and, worse, killed whatever model another session had loaded.

/v1/models lists a loaded GGUF under its bare repo id (e.g. unsloth/Qwen3-1.7B-GGUF),
so _resolve_model never matched the `:QUANT`-suffixed request. It then POSTed
/api/inference/load with model_path=org/repo:QUANT, which (a) Hugging Face rejects
("Repo id must use alphanumeric chars, '-', '_' or '.'") and (b) evicts the model the
other session was using, so a second 'unsloth start' in a new tmux/terminal tore down
the first. Re-running the command then attached to the now-empty server, which is why
it 'worked the second time'.

Mirror the org/repo:QUANT -> org/repo + --gguf-variant QUANT shorthand that
'unsloth run' and llama.cpp already accept, splitting it in _connect before we match or
serve. Matching now resolves against the loaded bare repo id (no spurious reload, no
eviction), and any real load uses a valid repo id plus gguf_variant. An explicit
--gguf-variant still wins; local paths and Windows drive letters pass through untouched.
The auto-serve path likewise spawns 'unsloth run --model org/repo --gguf-variant QUANT'.

* start: harden auth-key handling, codex teardown, and CI transcript redaction

Three review findings:

1. CI could leak a live key. agent-guides-drive.sh printed the raw
   'unsloth start --no-launch' transcript (which carries export UNSLOTH_API_KEY /
   ANTHROPIC_AUTH_TOKEN lines) to the Actions log on both the failure path and the
   success path before redact() ran. Add cat_redacted() and use it for those two
   prints, so the key is scrubbed on the way to the log while the on-disk file stays
   intact for the env parsing that follows.

2. Outages masqueraded as bad keys. _key_accepted caught a broad Exception and
   returned False, so a 5xx or timeout while checking a cached key looked like a
   rejection: it discarded a good key and minted extra ones (local) or reported 'no
   saved key' (remote). Only treat HTTP 401/403 as a rejection; let other errors
   propagate so a real outage surfaces.

3. Codex preflight could leave the auto-started server up. _require_gguf_for_codex
   runs after _connect may have auto-started Studio but before _run installs its
   teardown finally, so a preflight rejection (e.g. a transformers-backend model) left
   the server holding the port/GPU until the atexit backstop. Tear it down explicitly
   at the point of failure.

Tests: a 5xx on a saved key surfaces without minting; a non-GGUF codex preflight
tears down the auto-served server.

* start: fix IPv6/portless studio URLs, Pi config-dir isolation, and Pi install recipe

Four review findings:

1. Pi ignored the session config when PI_CODING_AGENT_DIR was already set. Pi's
   getAgentDir() reads process.env.PI_CODING_AGENT_DIR before falling back to
   $HOME/.pi/agent, so a value inherited from the user's shell sent Pi to their real
   config and skipped our provider/key (the HOME relocation alone was not enough). Pin
   PI_CODING_AGENT_DIR at the session's .pi/agent dir; it is path-valued so the WSL
   bridge translates it automatically.

2. Pi install hint dropped Pi's documented --ignore-scripts. Pi's README installs with
   'npm install -g --ignore-scripts @earendil-works/pi-coding-agent' and notes it needs
   no install scripts, so accepting the prompt now follows that safe recipe.

3. Auto-start ignored a portless UNSLOTH_STUDIO_URL. unsloth run binds to
   'parsed.port or 8888', so http://127.0.0.1 launched the child on 8888 but the health
   poll (and the returned base) still used port 80, stalling until the startup timeout.
   Normalize the base to host:8888 (IPv6-safe) before starting and polling.

4. API-panel command mistook IPv6 loopback for the bare default. The bare 'unsloth
   start' only probes 127.0.0.1:8888 on the IPv4 stack, so http://[::1]:8888 must carry
   an explicit UNSLOTH_STUDIO_URL. Drop ::1 from the bare-default host set while keeping
   it a loopback host (URL emitted, no key needed).

Tests: PI_CODING_AGENT_DIR is set to the session dir; _effective_base normalizes
portless/IPv6 bases; a portless UNSLOTH_STUDIO_URL auto-serves on :8888.

* start: apply fresh-review findings across CLI, CI, and the API-panel command

From a fresh multi-reviewer pass over the merged head plus the latest Codex bot review:

1. Load knobs now always consult the server. _resolve_model matched on model id alone,
   so --gguf-variant / --context-length / --no-load-in-4bit / --tensor-parallel were
   silently ignored whenever the id was already loaded (asking for UD-Q4_K_XL kept a
   Q8_0 serving). With any explicit knob the CLI defers to /api/inference/load, whose
   already-loaded dedup answers without reloading when variant and settings match, so a
   second session running the same command still attaches without evicting the first.

2. OpenCode --yolo and the session model pin now ride in OPENCODE_CONFIG_CONTENT. A
   project's own opencode.json outranks OPENCODE_CONFIG, so a repo config could silently
   override the session model and the --yolo permission block; OPENCODE_CONFIG_CONTENT
   outranks project config. The API key stays in the private file, never in printed env.

3. The --no-launch recipe's last line is a self-contained one-liner (inline VAR=value
   assignments before the command, conflicting vars blanked). People copy just the last
   line, and a bare codex/claude there ran against the user's real ~/.codex or Anthropic
   credentials with zero isolation, e.g. inheriting a pre-existing damaged ~/.codex
   state DB and blaming the recipe. The CI drive script scrubs the key from the one
   'invoking:' echo this adds.

4. The auto-serve log is 0600 and the parent handle is closed. It sat world-readable in
   the shared tempdir under a predictable name while carrying the minted sk-unsloth-
   key from the unsloth run banner.

5. _key_accepted fails with a clean message on outages. Non-auth errors (5xx, network,
   timeout) surfaced as a raw traceback; 401/403 still mean a rejected key.

6. _effective_base strips URL paths, and https loopback targets never auto-serve.
   http://127.0.0.1:8888/studio polled /studio/api/health (404) and https://127.0.0.1
   polled the wrong scheme, both spinning until the 15-minute startup timeout.

7. API-panel command: only literal 127.0.0.1:8888 earns the bare command. localhost can
   resolve to ::1, which the bare CLI never probes, so it keeps UNSLOTH_STUDIO_URL.

8. CI artifact sweep covers redacted-configs/ and agent-workdir/, not just logs/.

Tests: 125 CLI tests pass (new coverage for each fix), 156 backend tests pass, ruff
clean. Adds an unsloth connect alias regression test.

* start: hand Pi a clean screen at launch

Pi paints inline from wherever the cursor sits: its first render assumes a
clean screen instead of clearing or entering the alternate screen itself
(current Pi never emits a clear at startup). Launched under unsloth start,
that left the session starting mid-scroll beneath the connection output.
Clear the screen (click.clear, cross-platform, no-op without a TTY) right
before the Studio banner so Pi opens exactly one line down on a clean
viewport. Launch path only: --no-launch recipes and piped output are never
wiped, and alternate-screen agents are left alone.

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

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

* start: auto-override hermes' 64K context floor for small model windows

Hermes refuses to initialize when the served model's context window is
under 64,000 tokens, and a second copy of the same check rejects the
compression model mid-session. write_hermes_config previously pinned the
real window, so any small local model (e.g. 40,960) failed at startup
with manual config.yaml instructions.

For windows below the floor the recipe now claims 65,536 in
model.context_length, scales compression.threshold so compaction still
fires at 90% of the real window, and sets
auxiliary.compression.context_length to cover the mid-session check.
Windows at or above the floor keep the exact previous behavior.

* ci: install pi with --ignore-scripts, matching the start.py hint

The pi cell predates the pi recipe in start.py and still installed the
package with lifecycle scripts enabled, so CI stopped exercising the
exact command users are prompted to run. npm_retry now passes extra
flags through, the pi branch mirrors the install hint verbatim, and the
stale no-recipe comment is refreshed.

* ci: fail loudly when a relocation var is missing from connect output

The empty-string guards ran after appending /config.toml or /config.yaml,
so they could never fire: crosscheck_contract silently skipped its
contract checks and patch_hermes_tools died on the root path with a bare
traceback. Check the raw variable first and guide_fail with the real
cause.

[Studio] Add --with-llama-cpp-dir installer flag to reuse a local llama.cpp (#6472)
* Add --with-llama-cpp-dir flag to install.ps1 and install.sh

Users can now pass --with-llama-cpp-dir /path/to/llama.cpp to the
installer to skip downloading or building llama.cpp and use a local
directory instead. A junction (Windows) or symlink (Linux/macOS) is
created at the canonical install location, bypassing both the prebuilt
download (Phase 3) and source build (Phase 4) steps in setup.ps1/setup.sh.

The path is passed via UNSLOTH_LOCAL_LLAMA_CPP_DIR env var which
setup.ps1 and setup.sh read directly.

Ported from the idea in unslothai/unsloth#4384, reimplemented against
current Studio architecture.

* test: add static wiring test for --with-llama-cpp-dir flag

Cross-checks install.sh, install.ps1, studio/setup.sh and studio/setup.ps1
so the flag's contract (parse -> UNSLOTH_LOCAL_LLAMA_CPP_DIR env var -> link
local dir, skip prebuilt download and source build) can't silently regress.
Wired into studio-backend-ci.yml alongside the other tests/sh installer tests.

* Address review feedback on --with-llama-cpp-dir flag

- setup.ps1: delete an existing junction/symlink via DirectoryInfo.Delete()
  instead of a recursive remove, which can traverse the link and wipe the
  user's real llama.cpp directory on PowerShell 5.1.
- setup.ps1: short-circuit the build chain when a local dir is linked so CMake
  never runs inside the user's checkout when it lacks a Windows-layout binary.
- install.sh / setup.sh: resolve paths with CDPATH= cd -P so a set CDPATH
  cannot corrupt the resolved path.
- install.sh: seed _WITH_LLAMA_CPP_DIR from UNSLOTH_LOCAL_LLAMA_CPP_DIR so an
  exported env var (piped-install style) is honored instead of being clobbered.
- setup.sh: create the root llama-quantize shim when linking a local source
  build so GGUF export's check_llama_cpp() still finds it.
- setup.sh / setup.ps1: drop a stale link before the custom-home ownership
  assert so re-runs with the flag stay idempotent.
- test: pin the new linked-dir build short-circuit.

* Harden --with-llama-cpp-dir against Codex/Gemini review findings

- install.sh: error when --with-llama-cpp-dir is the final arg with no path,
  matching the existing --package/--python post-loop guards (was a silent
  fallback to the normal prebuilt/source install).
- studio/setup.sh: canonicalize LLAMA_CPP_DIR before the self-link no-op
  compare. _RESOLVED_LOCAL is fully resolved while LLAMA_CPP_DIR was textual,
  so a symlinked $HOME made the guard miss and the rm -rf could wipe the
  user's real llama.cpp tree.
- studio/setup.sh: make the llama-quantize shim non-fatal; it writes through
  the link into the user's tree, which may be read-only (shared/CI cache),
  and under set -e a failed ln aborted an otherwise-good reuse.
- studio/setup.ps1: detect a broken junction via Get-Item -Force instead of
  Test-Path so a dangling link from a prior run is removed and mklink can
  relink to a new valid directory.
- studio/setup.ps1: use Copy-Item -LiteralPath so a source path containing
  [ ] isn't treated as a wildcard in the junction copy fallback.
- tests: update the wiring assertions for the LiteralPath copy and the
  canonicalized compare.

* Validate/reuse local llama.cpp tree and guard the in-use case

Addresses the second Codex pass on the --with-llama-cpp-dir flag:

- Validate the linked tree before disabling installs (setup.sh + setup.ps1):
  reusing a local dir skips BOTH the prebuilt download and the source build,
  so the dir must already contain a runnable llama-server (build/bin on
  Linux/macOS, build\bin\Release\llama-server.exe on Windows). Bail out with a
  clear message instead of linking an unbuilt/wrong-platform checkout and
  leaving Studio with no usable binary.
- Treat a canonical-path target as already linked when it holds a build
  (setup.sh + setup.ps1): point the flag at ~/.unsloth/llama.cpp itself and an
  existing build is reused (skip prebuilt + source) rather than clobbered by
  the staged prebuilt installer (which uses os.replace()/replace). An empty
  canonical dir still falls through to the normal in-place install.
- Abort when an in-use llama.cpp can't be removed on Windows (setup.ps1):
  Remove-Item -ErrorAction SilentlyContinue can silently leave a locked tree
  in place; detect that and stop with the same active-process message + exit 3
  the prebuilt path uses, instead of junctioning over a half-present dir.

Left as follow-up (already tracked by the PR author as a non-blocker): the
in-app "Update llama.cpp" updater does not yet recognize a local-link install
as externally managed; that fix belongs in studio/backend/utils/llama_cpp_update.py.

* Accept all backend llama-server layouts in --with-llama-cpp-dir validation

The linked-tree validation only accepted build/bin[/Release]/llama-server, but
LlamaCppBackend._layout_candidates() resolves a root-level llama-server first,
then build/bin, then build/bin/Release on Windows. A `make` build or a flat
release extract (binary at the dir root) was therefore rejected with a hard
installer failure even though Studio would have run it.

Validate the same candidate set the backend uses in both setup scripts, and add
wiring-test assertions so the check can't silently narrow again.

* Treat --with-llama-cpp-dir local links as externally managed

A --with-llama-cpp-dir install junctions/symlinks the canonical llama.cpp dir to
the user's own checkout, but two backend paths still treated it as a Studio-owned
tree:

- The in-app updater (llama_cpp_update) offered and could apply an official
  prebuilt over the link, writing through it into the user's checkout (or
  failing) and silently dropping the link the flag created.
- Orphan cleanup (LlamaCppBackend._kill_orphaned_servers) resolved the linked
  root into its kill allowlist, so a llama-server the user launched from the same
  checkout was classified as ours and killed on startup.

Detect the canonical dir being a symlink/junction (reparse point) and treat the
install as unmanaged: get_update_status reports unsupported, start_update refuses
with reason "local_link", and the linked root is left out of the orphan
allowlist. Adds behavioral tests (link vs plain dir, updater refusal, and the
spared-vs-killed orphan control).

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

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

* Add behavioral shell test for --with-llama-cpp-dir linking

The existing tests/sh/test_with_llama_cpp_dir_flag.sh is a static grep of the
scripts. This adds a behavioral test that extracts the real link block from
studio/setup.sh (by content anchors, with a self-validating extraction) and runs
it against hermetic fake dirs, asserting the outcomes that matter:

- an external CMake build links and arms neither the prebuilt download nor the
  source build
- a flat / make tree (root-level llama-server, no build/bin) is accepted too
- an unbuilt tree is rejected with a non-zero exit and no link left behind
- relinking over a stale link preserves the target's contents (no data loss)
- pointing at the canonical path is a no-op reuse, not a self-referential link

Symlink-identity checks run only where real symlinks exist (skipped on Windows
git-bash copy-mode); the link/skip/no-data-loss checks run everywhere. Wired into
studio-backend-ci.yml next to the static test.

* Install psutil in backend CI so orphan-cleanup tests run

The new orphan-cleanup tests import psutil for the process scan, but the Backend
CI deps step installed studio.txt plus a fixed extras list that omits it, so the
two tests failed with ModuleNotFoundError. Add psutil to both backend pytest dep
steps (kept in shared shape), and guard the import with pytest.importorskip so a
minimal env without psutil skips these tests instead of erroring.

Add FP8/FP4 compressed export to save_pretrained_merged (#6706)
* Add FP8/FP4 compressed export to save_pretrained_merged

Adds compressed-tensors export (for vLLM) to save_pretrained_merged /
push_to_hub_merged via llm-compressor, alongside the existing lora /
merged_16bit / merged_4bit / gguf / torchao paths:

    model.save_pretrained_merged("model", tokenizer, save_method="fp8")

Supported save_method values: fp8 (FP8_DYNAMIC), mxfp4, nvfp4 (W4A4) and
mxfp8. The LoRA is merged to 16bit at save_directory, then a quantized
checkpoint is written to save_directory + "-<fmt>". nvfp4 needs a small
calibration set (defaults to ultrachat, overridable via calibration_dataset).

Notes:
- llm-compressor is installed lazily on first use, pinning the current torch
  and transformers via a constraints file so they are not upgraded (a plain
  install pulls transformers>=5 and breaks Unsloth).
- Quantization runs in a separate process (unsloth/_compressed_quantize.py,
  launched by file path) so Unsloth's transformers attention patches do not
  interfere with the forward llm-compressor runs during calibration, mirroring
  how GGUF export shells out to llama.cpp.
- mxfp8 needs a newer llm-compressor (transformers>=5); it is recognised and
  raises a clear error until that stack is available.

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

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

* Address review: main-process guard, calibration subsampling, tokenizer + dtype handling

- Route the 16bit merge through unsloth_generic_save for both LoRA and full
  finetuned models, so non-PEFT models are written in 16bit consistently
  instead of saving the original (possibly quantized) weights directly.
- Honor is_main_process: only the main process quantizes and writes the
  compressed output, so distributed ranks do not race on the same dirs.
- Subsample an in-memory calibration Dataset before save_to_disk so large
  training sets are not fully copied to a temp dir.
- Tolerate a missing tokenizer in the converter (data-free exports); still
  require one for calibration based schemes.
- Open config.json via a context manager in both files.
- Drop the redundant nvfp4 entry from the unsupported-name check (fp4 covers it).

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

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

* Add direct LoRA to GGUF export and harden FP8/FP4 compressed export

- Run llm-compressor install and scheme check before the 16bit merge so
  unsupported schemes (e.g. mxfp8) fail fast without writing a checkpoint
- Only the main process installs, merges, quantizes and uploads; isolate
  hub pushes to a temp dir and clean all temp dirs in a finally
- Forward standard save kwargs (state_dict, max_shard_size, ...) to the merge
- Fall back to the first dataset split for Hub calibration ids
- Export LoRA adapters to GGUF via convert_lora_to_gguf.py: modernize
  save_pretrained_ggml/push_to_hub_ggml and add save_method="lora" to
  save_pretrained_gguf/push_to_hub_gguf; resolve base from the adapter config

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

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

* Fix LoRA GGUF shell-injection test and compressed export trailing-slash path

- Update tests/saving/test_save_shell_injection.py for the new delegation: the
  LoRA to GGUF conversion now lives in _unsloth_save_lora_gguf, so assert it
  passes argv as a list with no shell=True and that the legacy ggml wrappers
  delegate to it instead of calling subprocess.Popen directly
- Normalize the local save_directory before building the "<dir>-<fmt>" sibling
  so a trailing slash no longer nests the compressed output inside the 16bit dir

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

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

* Polish FP8/FP4 and LoRA GGUF export after review

- Warn (not silently downgrade) when an explicit quantization_method is not a
  valid LoRA GGUF outtype; default stays f16
- Correct the inference hardware note: MXFP8 is 8-bit (cc >= 8.9), only FP4
  needs Blackwell for full activation quantization
- Document that a local fp8/fp4 save keeps the 16bit merge at save_directory
  and writes the quantized checkpoint to save_directory + "-<fmt>"

* Use sequential calibration pipeline and validate Hub access early

- nvfp4 calibration no longer forces the memory-hungry "basic" pipeline. The
  quantization runs in a clean subprocess, so llm-compressor's default
  sequential pipeline (layer-by-layer onloading) works and lets large models
  that do not fit at once still calibrate; fall back to "basic" only if tracing
  fails
- For push_to_hub compressed exports, create/validate the repo up front so a bad
  token or denied repo fails before the merge and quantization instead of after

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

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

* Harden compressed export: explicit sequential pipeline, base-tokenizer calibration, GPU memory

- nvfp4 calibration now passes pipeline="sequential" explicitly (layer-by-layer
  onloading) instead of relying on the inferred default, with a "basic" fallback
- Calibration datasets with a messages column no longer require a chat template:
  base / non-chat tokenizers fall back to concatenating message contents
- Free the in-memory model's CUDA memory before the quantize subprocess loads its
  own copy from disk (best-effort, single-device non-quantized only; restored
  afterward), so a single GPU need not hold two copies at once
- Create the calibration temp dir in the system temp location instead of next to
  the save directory, avoiding stray dirs in the workspace

* Free the failed calibration model before the basic-pipeline retry

In the sequential -> basic NVFP4 fallback, release the partially-processed model
and clear the CUDA cache before loading a fresh copy, so the retry does not
transiently hold two model copies on the GPU.

* Harden calibration data handling and compressed-export edge cases

- Calibration messages without a chat template now handle multimodal (list)
  content, None content, and null message rows instead of crashing on join
- Raise a clear error when the calibration dataset is empty after subsampling
- Reset llm-compressor's global session before freeing the model in the
  sequential -> basic NVFP4 fallback, so the old model is actually released
- LoRA GGUF export accepts a single-element list quantization_method
- Attach datasets metadata to the pushed repo on compressed hub exports
- Warn (instead of silently) if the model cannot be restored to its device
- Raise a clear error if the LoRA base model id cannot be determined

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

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

* Handle DatasetDict calibration, MoE routers, and MTP models in compressed export

- Reduce an in-memory DatasetDict calibration set to a single split before row
  subsampling, so save_to_disk does not copy every split to the temp dir
- For MoE models, keep the router/gate unquantized and pass
  moe_calibrate_all_experts so every expert is calibrated
- Warn when a model carries MTP / speculative-decoding tensors that the
  compressed export does not include

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

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

* Support many more compressed-tensors schemes and address review

- Expand save_method to cover the full set of compressed-tensors preset schemes:
  FP8 (dynamic/static/block), INT8, W8A8, W8A16, W4A16(+asym), W4A8, W4AFP8,
  MXFP4(+A16), NVFP4(+A16), plus the gated MXFP8; calibration is used only for
  the static-activation schemes (FP8 static, NVFP4)
- Broaden the near-miss save_method error to cover int/w-prefixed names
- MoE: also keep the Qwen shared-expert gate unquantized
- Strip non-model-input columns from already-tokenized calibration data so the
  collator does not choke on a leftover messages column
- Forward the Hub token to the LoRA converter and the quantize subprocess so
  gated/private base models and calibration datasets work without a global login

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

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

* Collapse compressed-tensors export help line so ruff-format converges

The print line in print_quantization_methods needed two ruff-format passes to
reach a fixpoint (merge implicit string concat, then collapse the single-arg
print). pre-commit.ci applies one pass per run, so it kept reformatting. Land
the converged single-line form directly.

* Add CPU-only regression tests for the export API

Cover all export paths without a GPU, for slow CPU-only CI:
- pure-function checks of the compressed-tensors scheme registry and save_method
  normalization (aliases, calibration flags, near-miss errors)
- AST checks that every merged saver dispatches compressed export, the GGUF savers
  expose the lora branch, torchao routes PTQ/QAT, the public methods stay attached,
  and the export subprocesses remain shell-safe (argv list, sys.executable, no shell)
- monkeypatched dispatch checks that fp8/nvfp4/merged_16bit, the LoRA-GGUF outtype
  resolution, and torchao PTQ/QAT reach the right helper with the right arguments

* Run the CPU-only export tests in consolidated CI

tests/saving is --ignored by the Repo tests (CPU) job, so the new GPU-free export
tests are added by path to consolidated-tests-ci.yml (collection sanity + Bucket-A run),
alongside the existing CPU saving tests, so they actually execute on CPU CI.

* Add GPU GGUF export + llama-cli inference smoke test

tests/saving/test_gguf_export_and_inference.py: skipif no CUDA. Trains a tiny
phrase-imprinting LoRA, exports a full-model q8_0 GGUF (merge -> convert_hf_to_gguf
-> llama-quantize), asserts a valid GGUF (magic + size), and - when a llama-cli
binary is available - runs one bounded generation (byte cap + watchdog kill) and
asserts the trained phrase round-trips through HF -> GGUF -> quantize -> inference.
The llama-cli step skips gracefully since the export only builds llama-quantize.

* Fix variant mismatch in compressed (FP8/FP4) export

save_pretrained_merged(..., save_method=fp8/nvfp4, variant=...) forwarded
the variant into the intermediate 16bit merge, so Transformers wrote
variant-named shards (model.<variant>.safetensors). The converter
subprocess then reloaded that directory with the default weight filenames,
so the compressed export failed after doing the merge.

Pop the variant out of the intermediate merge (internal staging that the
subprocess reloads with default names) and forward it via --variant so it
is applied to the final compressed checkpoint instead. Add a CPU AST guard
for the contract.

* Harden export paths from review

- install_llm_compressor: fall back to uv pip when this interpreter has no
  pip seeded (uv-created/relocatable venvs), instead of failing with
  No module named pip.
- LoRA GGUF export: if convert_lora_to_gguf.py is missing (a prebuilt or
  reused CWD llama.cpp install carries binaries but not the converter
  script), force a dedicated source checkout that ships it.
- push_to_hub_gguf(save_method=lora): return on non-main ranks, matching the
  local save_pretrained_gguf lora branch, so only rank 0 converts/uploads.
- compressed export VLM detection: require a vision_config or a
  ForVisionText2Text architecture; a bare *ForConditionalGeneration also
  matches text seq2seq models (T5/BART/Whisper) and is no longer treated as
  a VLM on its own.
- GGUF GPU smoke test: drop SFTConfig(max_length=1024), which raises under
  newer TRL padding-free training; length enforcement is not needed here.

* Add imatrix option to GGUF export, enabling IQ low-bit quants

save_pretrained_gguf / push_to_hub_gguf gain imatrix_file:
  None        -> no imatrix (unchanged)
  '/path'     -> pass to llama-quantize --imatrix (a *.gguf_file is renamed to *.gguf)
  True        -> download the upstream unsloth/<base>-GGUF imatrix (imatrix_unsloth.dat or
                 .gguf_file), raising a clear error if none exists

An importance matrix unlocks the IQ low-bit quants (iq2_xxs, iq4_xs, ...), which were hard
disabled before. They are gated: requesting one without an imatrix raises a clear error.

- _resolve_imatrix_file resolves path/True (PEFT base first, normalized via get_model_name,
  derives unsloth/<base>-GGUF, copies out of the HF cache before renaming *.gguf_file).
- IMATRIX_QUANTS registry replaces the old commented-out IQ entries; save_to_gguf accepts a
  resolved imatrix and threads it into the quantize calls.
- The --imatrix flag is emitted by unsloth_zoo's quantize_gguf (companion change). save.py
  fails fast with an upgrade hint if the installed unsloth_zoo lacks the imatrix kwarg.

Tests: tests/saving/test_imatrix_export.py (CPU: resolution, repo derivation, IQ gate,
--imatrix wiring) wired into CI; tests/saving/test_gguf_export_and_inference.py extended with
GPU iq2_xxs/iq4_xs export + inference. Verified end to end on Llama-3.2-1B: imatrix
auto-downloaded, iq2_xxs/iq4_xs exported and run via llama.cpp.

Note: requires the companion unsloth_zoo quantize_gguf imatrix change.

* Address imatrix/compressed review feedback: unsloth org GGUF repo, fail-fast, calibration split

- imatrix auto-resolve (imatrix_file=True): derive the upstream repo as unsloth/<base>-GGUF
  instead of <org>/<base>-GGUF, so official bases (e.g. meta-llama/Llama-3.1-8B-Instruct) find
  the matching Unsloth GGUF imatrix repo rather than failing on a nonexistent meta-llama/...-GGUF.
- Resolve/validate the imatrix before the 16-bit merge in save_pretrained_gguf, so a bad path or
  an unavailable upstream imatrix fails fast instead of after a long, multi-GB merge.
- Compressed calibration: when a Hub dataset has no "train" split, resolve the first split name
  and slice it, instead of materializing the whole dataset just to take num_samples rows. Keeps
  the original materialize-then-subselect path as a last resort.

Tests: add unsloth/<base>-GGUF mapping for an official base id, and create the imatrix file in the
quantize_gguf flag test (quantize_gguf now validates the imatrix exists).

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* Close residual credential-probe gaps for PR #6696

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

Factored the shared scrub into secret_free_environ().

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

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

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

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

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

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

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

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

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

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

2c316862f8 docker: address review round 4 (jupyter probe, CPU messaging, llama EXDEV, %pip shim)
- docker-publish smoke + docker_confirm.sh probe Jupyter /login, not /api: the
  launcher always configures a password hash so /api returns 403 and curl -f
  would never flip the health flag (false build failure).
- entrypoint.sh CPU messaging: CPU mode covers Jupyter, GGUF tooling and
  llama.cpp (GGUF) Studio chat; training AND loading an Unsloth model
  (FastLanguageModel) still need a GPU, since from_pretrained runs CUDA probes.
- install_llama_prebuilt.py: rollback/activation moves used bare os.replace,
  which fails with EXDEV across overlayfs in a Docker build and fell back to a
  broken source build (no nvcc). Add is_cross_device_error + move_install_dir_aside
  (os.replace fast path, copy+remove on EXDEV; busy errors still re-raise).
- notebooks: %pip / %uv line magics and the `!python -m pip` form bypassed the
  PATH pip/uv shim and could overwrite the baked cu128 torch/vLLM stack. Add
  unsloth_nb_pip_magic.py to re-point them at the shim, wired via the IPython
  startup hook and installed into the venv site-packages.

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

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

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

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

d476c7764b docker: address review round 3 (notebook -r filter, studio zoo ref, pinned notebooks commit)
- unsloth_pip_shim.py: filter protected packages out of a notebook
  `pip install -r requirements.txt`. The -r value was passed to the real pip
  unchanged, so torch / transformers / vLLM / nvidia pins inside the file could
  overwrite the baked cu128 stack or push transformers into the base venv.
  _filter_requirements_file() applies the same _KEEP / transformers-sidecar
  rules per line, writes the survivors to a temp file, keeps comments, option
  lines, nested includes and urls verbatim, and records a pinned transformers
  version for the sidecar.

- install.sh + Dockerfile.studio + docker-publish.yml: forward the resolved
  unsloth-zoo ref into the Studio build. install.sh --local overlaid
  unsloth-zoo from git main regardless of the operator-requested or base-image
  ref, so the full image could run a different zoo than the base. install.sh
  now honors UNSLOTH_ZOO_REF across all four --local overlays, Dockerfile.studio
  passes UNSLOTH_STUDIO_ZOO_REF through to it, and the workflow resolves one zoo
  ref in the prepare job and shares it with both the base and Studio builds.

- Dockerfile + docker-publish.yml: pin unslothai/notebooks to one resolved
  commit. Each arch leg cloned HEAD independently, so the same tag could seed
  different baked templates and .unsloth_template_commit depending on the pulled
  platform. The prepare job freezes notebooks to one sha (like the llama.cpp
  prebuilt tag) and the Dockerfile fetches that single ref at depth 1.

0ebbdbb9cc docker: address review follow-ups (pip-shim flags, sync ownership, tags, zoo ref, arch list)
- pip shim: do not treat the value of an index-url / find-links / constraint flag
  as an install target. A cell like 'pip install --extra-index-url <url> torch'
  now no-ops after keeping the baked stack instead of exec'ing a bare
  'pip install --extra-index-url <url>' that fails. Positional . / url / vcs and
  -r/--requirement files still count as targets.
- notebook sync: on first boot, record only files we actually wrote (or that are
  byte-identical to the template), never a kept pre-existing user file; and on the
  GitHub refresh, treat a file present in DEST but absent from the sync state as
  user-owned and keep it. Previously a bind-mounted notebook was recorded as
  managed and then overwritten by upstream.
- docker-publish: add flavor latest=false to the Studio metadata steps too, so a
  v* tag push cannot emit an implicit :latest via metadata-action's latest=auto;
  :latest stays default-branch-only, and the smoke test pulls the published tag.
- unsloth-studio-update: resolve the unsloth-zoo ref independently of --ref (new
  --zoo-ref, else use the ref only when the zoo repo has it, else fall back to
  main) so 'update --ref <unsloth-tag/sha>' does not fail on a missing zoo ref.
- Dockerfile: drop 10.3 (compute_103) from TORCH_CUDA_ARCH_LIST in both the
  builder and runtime stages. B300 runs sm_100 SASS, and the bundled CUDA 12.8
  nvcc cannot compile compute_103 (added in 12.9), which broke arch-list-honoring
  source / JIT builds.

8402dcebdd docker-publish: pin one llama.cpp prebuilt release across both arch legs
The base build-args never passed LLAMA_PREBUILT_TAG, so the Dockerfile fell back
to latest and each matrix leg resolved whatever unslothai/llama.cpp release was
current at its own build time. If latest moved between the amd64 and arm64 legs,
one published manifest could carry different GGUF binaries per arch.

Resolve the release once in a new prepare job (explicit llama_prebuilt_tag
dispatch input for a frozen build, else follow the /releases/latest redirect to a
concrete tag, mirroring docker/build.sh) and pass that single tag to both legs.

8f693c6207 docker: fix notebook pip-shim drops, first-boot overwrite, base :latest tag, arm64 decord
- pip shim: count editable/local/url/vcs targets (-e ., ., git+https, wheel
  URLs) as install targets, not just canonical package names, so they are no
  longer silently skipped inside notebooks
- notebook sync: never overwrite a pre-existing user notebook on first boot
  (match the refresh path's ownership rule); skip .unsloth_sync_state.tmp when
  recording state so it is not tracked as a managed file
- docker-publish: set flavor latest=false on the base image metadata so a v*
  tag push cannot publish :latest from the base image (the Studio image owns it)
- notebook deps: pin to tested versions and install decord on its own, hard on
  amd64 and fail-soft on arm64 (no aarch64 wheel) so the arm64 base build works

053a4f3853 docker-publish: clean build-args + add least-privilege default permissions
- Move the explanatory prose out of the two `build-args:` blocks.
  docker/build-push-action forwards every non-empty line verbatim, so a
  leading-# line is passed as a bogus --build-arg; the comments now live above
  each block. This workflow has not run yet, so the issue was latent.
- Add a top-level `permissions: contents: read` default so every job (including
  smoke-test, which had none) limits the GITHUB_TOKEN. The merge jobs keep their
  own `packages: write` blocks. Addresses the CodeQL "workflow does not contain
  permissions" findings.

Verify linuxdeploy AppImage digest before use in desktop release (#6673)
* Verify linuxdeploy AppImage digest before use in desktop release

The desktop release workflow downloaded linuxdeploy-x86_64.AppImage from a
GitHub release and ran chmod +x with no integrity check. Pinning the
versioned release path is reproducibility, not integrity: a release asset
can be replaced (or its delivery path compromised) after upload. The next
step builds the AppImage with the Tauri signing private key and a
contents:write GITHUB_TOKEN in scope, so a substituted linuxdeploy that
ran during packaging could exfiltrate signing material or tamper with
published release artifacts.

Pin the immutable SHA-256 of the asset and verify it with sha256sum -c
before chmod +x, so a mismatch fails the job closed before the binary is
ever executable. Extend the existing in-workflow guard to require both the
pinned digest and the verification step, so a future edit cannot silently
drop the check.

* Scope linuxdeploy guard to real step content, not its own text

The self-check searched every workflow line, so the digest assertion was
satisfied by the guard's own expectedLinuxdeployDigest line and the
verification assertion by a comment. Deleting the LINUXDEPLOY_SHA256 env
pin or the actual sha256sum -c command would still have passed.

Match the digest against the LINUXDEPLOY_SHA256 env line specifically and
require sha256sum -c on a non-comment line, so dropping either the pin or
the verification now fails the guard.

* Scope linuxdeploy guard to the Pin step block and check ordering

The previous predicate still scanned the whole workflow, so the literal
sha256sum -c in the guard's own code satisfied the verification check; a
deleted or post-chmod verification command would still pass.

Extract the 'Pin linuxdeploy for AppImage' step block and assert within it:
the LINUXDEPLOY_SHA256 env pins the expected digest, a non-comment line
runs sha256sum -c, and that verification precedes chmod +x.

Withhold HF_TOKEN from pull_request CI runs (#6600)
* Withhold HF_TOKEN from pull_request runs of CI workflows

The pull_request-triggered CI workflows check out and execute PR-controlled
code (install.sh, .github/scripts/**, tests/**) with secrets.HF_TOKEN in the
step environment. For a same-repo PR, GitHub provides repository secrets to the
run, so a malicious or compromised branch could modify a checked-out script to
read and exfiltrate HF_TOKEN, including by writing it into the uploaded logs/
artifact. HF_TOKEN is an external Hugging Face credential of unknown scope, so
this is the high-value exposure.

Gate every HF_TOKEN reference in these workflows with
`github.event_name != 'pull_request' && secrets.HF_TOKEN || ''`, so the real
token flows only on the trusted schedule/push/workflow_dispatch runs and PR runs
see an empty string. All model repos used by these jobs are public
(unsloth/*-GGUF), so anonymous download still works on PRs; install_llama_prebuilt.py
only sends HF auth to Hugging Face hosts and tolerates an absent token.

GITHUB_TOKEN (passed as GH_TOKEN) is intentionally left in place: it is the
auto-provisioned, job-scoped, contents:read token that expires with the job and
gives a same-repo PR author nothing they do not already have, and
install_llama_prebuilt.py needs it to authenticate the GitHub releases API or
the prebuilt llama.cpp download hits the anonymous rate-limit bucket and 403s.

* Trim the HF_TOKEN gating comments to one line per site

Comment/whitespace-only: collapse the per-step rationale to a single line and
shorten the local-agent-guides header note. No workflow logic changes (verified
each file's parsed YAML is identical before/after).

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

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

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

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

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

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

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

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

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

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

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

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

* Tighten code comments (no logic change)

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

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

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

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

CI: fix import-hoist false positive, vision-cache test cwd, llama.cpp CLI smoke (#6598)
Three independent upstream CI fixes that currently fail on every open PR:

verify_import_hoist.py: TARGET-CHANGED only flags a genuine swap (a BEFORE
target no longer reachable in AFTER). A pure superset growth such as adding
import urllib.error next to import urllib.request binds the same top-level
package and loses nothing, so it is no longer a blocker (transformers_version.py).

test_vision_cache.py: run each test from a fresh empty cwd. is_vision_model
calls is_local_path first, and a relative model id that happens to exist on
disk short-circuits before the mocked detection runs; the CI cwd and HF cache
can contain dirs colliding with the synthetic ids, causing 'called 0 times'.
Production code is correct; only the test needed cwd isolation.

consolidated-tests-ci.yml: the llama.cpp smoke probes the first of
llama-cli / llama-mtmd-cli / llama-server that exists instead of hard-requiring
llama-cli, which upstream no longer always builds. llama-cli stays first so it
is preferred when present. Adds Windows .exe + build/bin/Release handling.

Add Local Agent Guides CI (#6547)
Boot `unsloth run --disable-tools` against a small GGUF and drive each
supported coding agent (claude, codex, hermes, openclaw, opencode, pi)
through its documented `unsloth connect <agent> --no-launch` recipe, so
the connect flow in unsloth_cli/commands/connect.py stays exercised end
to end and regressions surface as a failing check.

Per-agent matrix, three jobs:
- connection: assert a non-empty, error-free reply to a trivial prompt
- file-edit: a two-turn create-and-run hello.py test (dispatch/schedule
  only, skipped on pull_request)
- prompt-cache: verify llama.cpp prefix-cache reuse across requests

The GitHub-hosted runners are CPU-only, so each request is trimmed to
the smallest prompt that still drives the recipe: claude with --tools to
drop unused tool schemas (--allowedTools only gates permission, it does
not shrink the prompt), hermes with an empty platform_toolsets.cli, and
openclaw with a minimal agent definition. hermes and openclaw run a
multi-turn tool loop in file-edit that a CPU runner cannot finish in
time, so those two cells are best-effort; their endpoint wiring is still
hard-gated by the connection job.

A preflight step HTTP-checks each agent's API dialect before install so a
server-side contract regression is reported separately from agent or
guide drift.

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

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

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

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

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

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

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

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

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

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

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

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

Follow-up to PR #6296.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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