Gate run_server re-exec behind allow_reexec so embedders are not restarted

run_server is a library/embed entry point (colab.start calls it directly), so the
unconditional os.execv for the torch CUDA LD_LIBRARY_PATH fix would replace the live
Colab/Jupyter kernel and drop in-memory state. Gate the re-exec behind a new
allow_reexec flag defaulting to False; the run.py __main__ path already re-execs
before calling run_server, and the unsloth_cli studio/ui entrypoints opt in with
allow_reexec=True so the CLI keeps the CUDA LD fix.

-# Prompt-cache (KV-cache prefix reuse) detection, two strategies in one helper:
-#
-#   mode=api     A 2-turn /v1/chat/completions probe. Turn 2 prepends turn 1 +

-#                KV cache. Asserts usage.prompt_tokens_details.cached_tokens > 0
-#                on turn 2. This is the OpenAI-dialect server cache sanity.
-#                WHY this works on chat completions: the chat path forwards
-#                llama-server's real cached_tokens through
-#                studio/backend/routes/inference.py:482-489 (_prompt_tokens_details)
-#                into prompt_tokens_details (inference.py:519).
-#
-#   mode=log     Read the llama-server log and decide HIT vs MISS from the
-#                prompt-reprocessing trace. WHY the log (not the API field):
-#                the Anthropic /v1/messages path builds AnthropicUsage(
-#                input_tokens=..., output_tokens=...) at inference.py:8787-8790
-#                / :8829-8832 and NEVER sets cache_read_input_tokens, which
-#                therefore stays at its model default of 0
-#                (studio/backend/models/inference.py:1655). So an Anthropic-path
-#                client (Claude Code, OpenClaw is openai-completions but Claude
-#                Code is the canonical Anthropic agent) can get a real KV-cache
-#                hit that the API usage field reports as 0. The only ground
-#                truth for the Anthropic path is the llama-server log.
-#
-# Log location (verified): studio/backend/core/inference/llama_cpp.py:4363-4365
-#   _swa_cache_path().parent/"logs"/"llama-server"/llama-<ts>[label]-port-<P>[-try<N>].log
-#   _swa_cache_path() => $UNSLOTH_STUDIO_HOME|$STUDIO_HOME or ~/.unsloth/studio
-#   (llama_cpp.py:337-340). So default: ~/.unsloth/studio/logs/llama-server/.
-#
-#   <P> is the INTERNAL llama-server port (self._find_free_port(),
-#   llama_cpp.py:3489 / :4641) -- a RANDOM port, NOT the Unsloth port. So we must
-#   NOT filter the log glob by STUDIO_PORT (the brief's `port-<STUDIO_PORT>`
-#   glob would never match). We pick the newest llama-*.log instead.

-# Why this exists
-# ---------------
-# huggingface_hub 1.15+ deprecated `hf_transfer` and routes every
-# transfer through the `hf-xet` binary package. In CI we observed
-# `hf download` on a 3 GB GGUF (gemma-4-E2B-it-UD-Q4_K_XL) progress
-# to ~46% via Xet, then go completely silent for the remainder of
-# the 30-min job timeout -- no progress bytes, no error, no exit.
-# A sibling 940 MB mmproj on the same step downloaded in ~21s
-# moments earlier, so the hang is per-file inside hf-xet rather
-# than a network outage. The Xet env-vars below put hf-xet into
-# its highest-throughput mode and force a 500 s client-read
-# timeout; the watchdog loop ensures a stall does not eat the
-# whole job: if the hf process has not exited after STALL_S
-# seconds (default 180 = 3 min), we SIGTERM, then SIGKILL, then
-# start a fresh attempt. Retries are unbounded -- the enclosing
-# GitHub Actions job's `timeout-minutes` is the real bound.
-#
-# See https://huggingface.co/docs/huggingface_hub/package_reference/environment_variables
-# for the HF_XET_* documentation, and npm/cli#7308's pattern (silent
-# CI hang with no error) for prior art on this class of failure.

-# Boot `unsloth run --disable-tools` in the background, wait for it to be

-# /v1/models id. Exports everything downstream steps need into $GITHUB_ENV
-# (or prints it when run outside Actions). Factored out of the workflow so

-#
-# Why a helper and not inline YAML
-# --------------------------------
-#  * Every `unsloth run` invocation here is the *Unsloth server* under test.
-#    A failure to come up healthy is class (a) "server/API regression" and
-#    must be reported with a distinct `::error::` BEFORE any agent runs.
-#  * The banner is the documented contract a human copies from. We parse the
-#    exact `API Key:` line printed by unsloth_cli/commands/studio.py
-#    (`  API Key:      <key>` non-silent, `API Key: <key>` silent) so a
-#    silent change to that line is also caught.
-#  * `unsloth run` re-execs into the studio venv ($STUDIO_HOME/unsloth_studio),
-#    so in CI after `install.sh --local` it runs the PR's repo code.
-#
-# Outputs written to $GITHUB_ENV (and echoed):
-#   UNSLOTH_API_KEY        the sk-unsloth-* key minted on the banner
-#   UNSLOTH_STUDIO_URL     http://127.0.0.1:<PORT>  (so `unsloth start`
-#                          finds THIS server, not the hardcoded :8888)
-#   UNSLOTH_BASE_URL       same as UNSLOTH_STUDIO_URL (alias for clarity)
-#   UNSLOTH_MODEL_ID       the canonical id reported by /v1/models
-#   UNSLOTH_SERVER_PID     pid of the backgrounded `unsloth run`

-# Local Agent Guides CI
-# =====================
-# Detects when our local-agent setup recipes drift out of sync with
-# `unsloth run`. Boots a real `unsloth run --disable-tools` server and
-# drives the coding agents end to end through the *exact* recipes defined
-# in unsloth_cli/commands/start.py (the in-repo source of truth -- there
-# is no docs/ tree). Wherever start.py has a recipe we drive the agent
-# via `unsloth start <agent> --no-launch` and execute what it prints, so
-# the test self-updates against start.py and catches silent recipe drift.
-#
-# Source-of-truth files this workflow guards:
-#   unsloth_cli/commands/start.py   the `unsloth start <agent>` recipes
-#   unsloth_cli/commands/studio.py    the `unsloth run` banner (API Key line)
-#
-# Failure taxonomy (each surfaced with a distinct ::error:: + the agent name
-# + the start.py location, so a red X is immediately triageable):
-#   (a) Unsloth server/API regression -- the dialect HTTP preflight fails
-#       BEFORE the agent runs (or the server never becomes healthy).
-#   (b) Agent package install failed   -- npm/curl install of the CLI failed.
-#   (c) Guide drift                    -- preflight passed + install ok, but
-#       the documented `unsloth start` flow produced no/garbled output.
-#
-# Agents covered (6): claude, codex, hermes, openclaw, opencode, pi.
-#   - All six have a `unsloth start <agent>` recipe, so each cell obtains its
-#     env + command from `unsloth start <agent> --no-launch` and runs THAT
-#     (self-updating: a recipe change is exercised automatically).

-# This workflow is intentionally separate from security-audit.yml:
-#   - security-audit.yml is the umbrella job (pip-audit + npm audit +
-#     cargo audit + OSV + Semgrep + secret scanning + SBOM + ...);
-#     it takes ~25 minutes and runs only when dep manifests change.
-#   - lockfile-audit.yml is a ~30 second pure-Python parse + grep on
-#     the lockfiles themselves; it runs on every PR that even nudges
-#     a lockfile so reviewers always see the audit result inline.

-# Focused PR gate for the MLX dispatch surface, running on a real
-# Apple Silicon runner.
-#
-# Runner: macos-14 (M1, 3 vCPU / 7 GB / Apple Silicon standard runner
-# -- FREE for public repositories per the GitHub Actions billing
-# reference; larger variants like macos-14-large/-xlarge are paid so
-# we deliberately avoid those).
-#
-# Why a single Mac job (no Linux+spoof leg): the dispatch tests are
-# 100% spoofed monkeypatches and run identically on any host, so the
-# Linux leg was duplicating the matrix tests already covered on Mac
-# while missing everything Apple-specific. The Mac job runs the SAME
-# spoofed matrix PLUS three things only a real Apple Silicon host
-# can prove:
-#
-#   1. unsloth._IS_MLX flips True on Darwin+arm64 with mlx genuinely
-#      installed (no spoof).
-#   2. Every PR-A MLX-only unsloth_zoo module (mlx_loader, mlx_trainer,
-#      mlx_compile, mlx_utils, mlx_cce, gated_delta_vjp) imports
-#      against the real `mlx` + `mlx-lm` + `mlx-vlm` PyPI wheels --
-#      each does `import mlx.core as mx` at module top level, so this
-#      catches a future change that breaks the real wheels without
-#      needing a Mac developer in the loop.
-#   3. The hardware-dispatch spoofs do not collide with the real
-#      environment (the test fixture installs a MetaPathFinder that
-#      blocks `import mlx.core` for "no-mlx" profiles, faithfully
-#      simulating a Mac without mlx even when mlx IS installed).
-#   4. End-to-end MLX training + inference smoke test:
-#      run_real_mlx_smoke.py trains unsloth/gemma-3-270m-it for 7
-#      deterministic LoRA steps on a single repeated text row, then
-#      verifies the trained model can complete the prompt and that
-#      losses + grad norms are finite and well-behaved. This is the
-#      only place in CI that exercises a real MLX backward pass +
-#      optimizer step + inference call.
-#
-# Three dispatch test files documented in tests/studio/README.md:
-#   - test_hardware_dispatch_matrix.py    parametrized 7-profile matrix
-#                                         + 2 dispatch-priority canaries
-#   - test_is_mlx_dispatch_gate.py        AST + runtime guard on
-#                                         unsloth._IS_MLX
-#   - test_mlx_training_worker_behaviors.py  AST contract checks on
-#                                            studio/backend/core/training/worker.py
-#
-# Surfaces a single PR check ("MLX CI on Mac M1 / dispatch").
-#
-# Security audit footprint: every package this workflow installs is
-# already covered by .github/workflows/security-audit.yml -- the deps
-# come from studio/backend/requirements/studio.txt and unsloth-zoo's
-# pyproject (resolved transitively). The git+ install of unsloth-zoo
-# is intentionally skipped by the audit (pip-audit cannot resolve a
-# git URL through PyPI metadata; the audit comment in security-audit.yml
-# documents this). No new package is introduced solely by MLX CI.

-      #    torch.cuda / torch.xpu / torch.backends.mps via monkeypatch

-# Mac counterpart to studio-update-smoke.yml. Verifies that on a real
-# Apple Silicon (macos-14, M1) runner:
-#
-#   1. install.sh --local --no-torch installs Unsloth AND auto-fetches
-#      the prebuilt llama.cpp Mac binary (llama-bNNNN-bin-macos-arm64
-#      from ggml-org/llama.cpp). Hitting the source-build fallback is
-#      treated as an Unsloth bug -- Unsloth must always pick the
-#      prebuilt on Mac.
-#   2. unsloth studio update --local is idempotent. Two consecutive
-#      runs both report "prebuilt up to date and validated", no
-#      source-build fallback.
-#   3. The installed Unsloth still boots and /api/health returns
-#      healthy after the update path.

-# End-to-end Unsloth chat UI smoke via Playwright + Chromium against a
-# headless Linux runner. Boots Unsloth with the smallest GGUF
-# (gemma-3-270m-it UD-Q4_K_XL, ~254 MiB), drives the actual frontend
-# bundle, and asserts the full bootstrap-password / change-password /
-# send-message / persist-on-reload journey works end to end.
-#
-# This is the only workflow that catches regressions in the wiring
-# between the React frontend and the FastAPI backend, e.g. assistant-ui
-# version drift, /api/auth response shape changes, runtime-provider
-# regressions, or chat-history persistence breaking. Backend-only and
-# frontend-only CI happily pass while the actual user-visible UI is
-# broken (cf. the 2026.5.1 chat-history release).

-# Windows counterpart to studio-update-smoke.yml /

-# windows-latest runner:
-#
-#   1. install.ps1 --local --no-torch installs Unsloth AND auto-fetches
-#      the prebuilt llama.cpp Windows binary (app-<tag>-windows-x64-cpu
-#      from unslothai/llama.cpp). Hitting the source-build fallback is
-#      treated as an Unsloth bug -- Unsloth must always pick the
-#      prebuilt on Windows.
-#   2. unsloth studio update --local is idempotent. Two consecutive
-#      runs both report "prebuilt up to date and validated", no
-#      source-build fallback. The CLI's _find_setup_script picks
-#      setup.ps1 on Windows automatically.
-#   3. The installed Unsloth still boots and /api/health returns
-#      healthy after the update path.

-# Cross-version compat canary for the four upstream packages whose
-# release cadence regularly breaks unsloth + unsloth-zoo:
-#
-#   1. vLLM             (LoRA worker manager, BnB loader, cumem allocator)
-#   2. TRL / GRPO       (trainer source rewriters in unsloth.models.rl*)
-#   3. PEFT             (LoraConfig, get_peft_model, LoraLayer, bnb integration)
-#   4. sentence-transformers (Transformer/Pooling/Normalize, Trainer)
-#   5. bitsandbytes     (Linear4bit, dequantize_4bit)
-#
-# Strategy: GitHub raw-fetch + symbol grep against every tracked
-# version (no pip install, CPU-only). When upstream renames a symbol
-# we depend on, the matching test fails BEFORE a user hits it. The
-# `main` branch entries give us a few-day lead on PyPI releases.

-Every release is a level-2 heading whose first token is the version, optionally
-followed by a date:
-
-```md
-## 2026.7.6 - 2026-07-22
-```
-
-`## [2026.7.6] - 2026-07-22` and `## v2026.7.6` also work. Everything under a
-heading, up to the next level-2 heading, is that release's notes and renders as
-Markdown in the popup.
-
-Notes are matched to one exact version. When Studio offers an update to
-`2026.7.6` it renders the `2026.7.6` section and nothing else. If that section
-is missing, the popup links out to the online changelog rather than showing
-notes from an unrelated release, so a new version needs its own section here
-before its notes can appear.
-
-Keep the newest release at the top. Lead each bullet with the change itself:
-the collapsed popup highlights the first sentence and dims the rest.
-`## Unreleased` is ignored by the popup, so it is safe to stage notes there and
-rename the heading at release time.
-
-<!-- Add new releases directly below this line. -->
-
-## Unreleased
-
-## 2026.7.5

-### What's Changed
-
-- AMD support is here. Train, run RL, chat with and deploy 500+ models on
-  Radeon, Instinct, Ryzen and data center GPUs across Windows, WSL and Linux,
-  up to 2x faster with 70% less VRAM and no accuracy loss.
-- Intel XPU support lands in Studio, so Arc and Data Center GPUs run chat and
-  training alongside the NVIDIA, AMD and Apple paths.
-- Local speech to text dictation runs fully offline, with slim Whisper bundles
-  and a picker for custom models.
-- DoRA training is available in Studio, selectable next to LoRA and full
-  fine-tuning in the training tab.
-- The update popup previews release notes inline, pulled from this file and
-  matched to the exact version being offered.
-
-### AMD, 23 July update
-
-Our AMD collaboration, custom Triton kernels and math algorithms bring local
-training and inference to AMD hardware. The 23 July update builds on the
-[AMD release](https://github.com/unslothai/unsloth/releases/tag/v0.1.501-beta):
-
-- RDNA2 and Gorgon Halo are supported, and the installer no longer fails to
-  detect GPUs on Strix Halo and other AMD cards.
-- RDNA4 handling is better, and HIP and ROCm failures are caught and fixed
-  automatically instead of stopping the install.
-- Unified memory safetensors loading is 2x faster, with much faster gradient
-  checkpointing on unified memory devices.
-- Voice dictation through whisper.cpp has preliminary support.
-- Rollback environments left by installs no longer eat 5GB of disk. They are
-  cleaned up automatically.
-
-Optimized ROCm builds cover GGUF and safetensors inference, and ROCm
-compatibility is improved for MI300X and MI325X. Full guide:
-[unsloth.ai/docs/basics/amd](https://unsloth.ai/docs/basics/amd).
-
-### Running larger models
-
-- Automatic GPU placement, or pick exactly which GPUs and layers to use.
-- Move MoE expert layers into system memory so larger models fit.
-- Split a model across several GPUs, or use tensor parallelism.
-- Hardware settings are saved per model and quant.
-
-### Also in this release
-
-- Remote access with `unsloth studio --secure` over free HTTPS via Cloudflare.
-- Web search reads PDF papers and manuals, and parallel tool calls, reasoning
-  output and tool retries are more reliable.
-- The model download location is configurable, so weights can live on a second
-  drive instead of the default cache.
-- Stalled Hugging Face XET downloads retry over standard HTTP, and existing
-  GGUF files are reused instead of downloaded again.

-## 🚀 Unsloth Start
-
-[Unsloth Start](https://unsloth.ai/docs/integrations/unsloth-start) connects [Claude Code](https://unsloth.ai/docs/basics/claude-code), [Codex](https://unsloth.ai/docs/basics/codex) and other agents to local models with one command.
-
-Start Unsloth, load a model, open your project folder, then run:
-
-```bash
-unsloth start claude
-```
-
-Replace `claude` with any supported agent:
-
-| Agent | Command |
-| --- | --- |
-| Claude Code | `unsloth start claude` |
-| OpenAI Codex | `unsloth start codex` |
-| Hermes Agent | `unsloth start hermes` |
-| OpenClaw | `unsloth start openclaw` |
-| OpenCode | `unsloth start opencode` |
-| Pi Coding Agent | `unsloth start pi` |
-
-Claude Code, Codex, OpenCode and Pi can keep their current model and use Unsloth as a local
-subagent:
-
-```bash
-unsloth start claude --as-subagent --model unsloth/model-GGUF:quant
-```
-
-## 📥 Install
+## ⚡ Quickstart
 Unsloth can be used in two ways: through **[Unsloth Studio](https://unsloth.ai/docs/new/studio/)**, the web UI, or through **Unsloth Core**, the code-based version. Each has different requirements.
 
 ### Unsloth Studio (web UI)
-Unsloth Studio (Beta) works on **Windows, Linux, WSL** and **macOS**.
+Unsloth Studio works on **Windows, Linux, WSL** and **macOS**.
 
-* **CPU:** Supported for Chat and Data Recipes currently
-* **NVIDIA:** Training works on RTX 30/40/50, Blackwell, DGX Spark, Station and more
-* **macOS:** Training, MLX and GGUF inference are ALL supported.
-* **AMD:** Training, RL, chat and deployment work on Windows, WSL and Linux. [Read the AMD guide](https://unsloth.ai/docs/basics/amd).
-* **Vulkan:** GGUF inference is supported on [compatible GPUs, including Intel GPUs](https://github.com/unslothai/unsloth/pull/5819). Vulkan accelerates GGUF inference only; training still requires a supported PyTorch or MLX backend.
+* **CPU:** Supported for **chat inference only**
+* **NVIDIA GPUs:** Training works on RTX 30/40/50, Blackwell, DGX Spark, DGX Station and more
+* **macOS:** Currently supports chat only; **MLX training** is coming very soon
 * **Multi-GPU:** Available now, with a major upgrade on the way
 
-#### macOS, Linux, WSL:
-```bash
-curl -fsSL https://unsloth.ai/install.sh | sh
+#### Windows, MacOS, Linux or WSL:
 ```
-Use the same command to update.
-
-To force the Vulkan llama.cpp backend, set `UNSLOTH_FORCE_VULKAN=1` **before installing or updating**. The setting selects the llama.cpp binary bundle, so setting it only when launching Studio cannot replace an existing CPU bundle:
-
-```bash
-export UNSLOTH_FORCE_VULKAN=1
-curl -fsSL https://unsloth.ai/install.sh | sh
+pip install unsloth
+unsloth studio setup
+unsloth studio -H 0.0.0.0 -p 8888
 ```
+Use our [Docker image](https://hub.docker.com/r/unsloth/unsloth) ```unsloth/unsloth``` container. Read our [Docker Guide](https://unsloth.ai/docs/get-started/install/docker).
 
-#### Windows:
-```powershell
-irm https://unsloth.ai/install.ps1 | iex
+You can also install directly from source:
 ```
-Use the same command to update.
-
-To force the Vulkan llama.cpp backend, set the environment variable before running the installer or updater:
-
-```powershell
-$env:UNSLOTH_FORCE_VULKAN=1
-irm https://unsloth.ai/install.ps1 | iex
+git clone https://github.com/unslothai/unsloth.git
+cd unsloth
+pip install -e .
+unsloth studio setup
+unsloth studio -H 0.0.0.0 -p 8888
 ```
 
-Re-running the current installer replaces a previously selected CPU bundle when the backend differs. A separate Vulkan SDK is not required; the GPU driver must provide a working Vulkan runtime.
-
-#### Launch
-```bash
-unsloth studio -p 8888
-```
-For LAN or cloud access, add `-H 0.0.0.0` (raw port only; add `--cloudflare` for a public URL). By default, Unsloth is accessible only locally.
-
-To reach Unsloth over HTTPS, use `unsloth studio --secure`. Unsloth stays bound to localhost and is reached only through a free Cloudflare tunnel, which publishes it at a public `https://*.trycloudflare.com` URL (it fails closed if the tunnel can't start, so the raw port is never exposed). This makes Unsloth reachable from the internet, so anyone with the link and API key can use it and run code: keep your API key private (see Remote access below).
-
-#### Docker
-Use our [Docker image](https://hub.docker.com/r/unsloth/unsloth) ```unsloth/unsloth``` container. Run:
-```bash
-docker run -d -e JUPYTER_PASSWORD="mypassword" \
-  -p 8888:8888 -p 8000:8000 -p 2222:22 \
-  -v $(pwd)/work:/workspace/work \
-  --gpus all \
-  unsloth/unsloth
-  ```
-
-#### Developer, Nightly, Uninstall
-To see developer, nightly and uninstallation etc. instructions, see [advanced installation](#-advanced-installation).
-
 ### Unsloth Core (code-based)
-#### Linux, WSL:
+#### Windows, Linux, WSL
 ```bash
-curl -LsSf https://astral.sh/uv/install.sh | sh
-uv venv unsloth_env --python 3.13
-source unsloth_env/bin/activate
-uv pip install unsloth --torch-backend=auto

-## 📥 Advanced Installation
-The below advanced instructions are for Unsloth Studio. For Unsloth Core advanced installation, [view our docs](https://unsloth.ai/docs/get-started/install/pip-install#advanced-pip-installation).
-#### Developer / Nightly / Experimental installs: macOS, Linux, WSL:
-The developer install builds from the `main` branch, which is the latest (nightly) source.
-```bash
-git clone https://github.com/unslothai/unsloth
-cd unsloth
-./install.sh --local
-unsloth studio -p 8888
-```
-To install into an isolated location (its own virtual env, `auth/`, `studio.db`, cache and llama.cpp build), set `UNSLOTH_STUDIO_HOME` and pass it again at launch:
-```bash
-UNSLOTH_STUDIO_HOME="$PWD/.studio" ./install.sh --local
-UNSLOTH_STUDIO_HOME="$PWD/.studio" unsloth studio -p 8888
-```
-Then to update :
-```bash
-cd unsloth && git pull
-./install.sh --local
-unsloth studio -p 8888
-```
-
-#### Developer / Nightly / Experimental installs: Windows PowerShell:
-The developer install builds from the `main` branch, which is the latest (nightly) source.
-```powershell
-git clone https://github.com/unslothai/unsloth.git
-cd unsloth
-Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass
-.\install.ps1 --local
-unsloth studio -p 8888
-```
-To install into an isolated location (its own virtual env, `auth/`, `studio.db`, cache and llama.cpp build), set `UNSLOTH_STUDIO_HOME` and pass it again at launch:
-```powershell
-$env:UNSLOTH_STUDIO_HOME="$PWD\.studio"; .\install.ps1 --local
-$env:UNSLOTH_STUDIO_HOME="$PWD\.studio"; unsloth studio -p 8888
-```
-Then to update :
-```powershell
-cd unsloth; git pull
-.\install.ps1 --local
-unsloth studio -p 8888
-```
-
-#### Remote access: `--secure` (HTTPS tunnel) vs raw port
-By default `unsloth studio` binds to `127.0.0.1` (this machine only). To reach it from another device, pick one of:
-
-- `--secure` (recommended): serve **only** through a free Cloudflare HTTPS link. Unsloth stays bound to localhost and the tunnel provides the public URL; it fails closed (does not start) if the tunnel can't come up, so the raw port is never exposed.
-```bash
-unsloth studio --secure -p 8888
-```
-- `-H 0.0.0.0`: bind the raw port on all network interfaces, reachable from anywhere on the network (subject to your firewall). It does not create a public internet URL; add `--cloudflare` to also publish an internet-reachable `https://*.trycloudflare.com` link even behind a firewall. Only use this on a network you trust.
-```bash
-unsloth studio -H 0.0.0.0 -p 8888
-```
-The Cloudflare tunnel is **off by default**: `-H 0.0.0.0` exposes the raw port only, not a public internet URL. Pair the wildcard bind with `--cloudflare` (`unsloth studio -H 0.0.0.0 --cloudflare`) to also publish a public `https://*.trycloudflare.com` link, or prefer `--secure` (above), which keeps the raw port private. `--cloudflare` has no effect on a loopback bind.
-
-On a wildcard bind Unsloth works out the address to share by asking `ifconfig.me` for the public IP, then asks `check-host.net` whether that port is reachable so it can tell you if a firewall is in the way. Both contact a third party. Set `UNSLOTH_STUDIO_DISABLE_PUBLIC_CHECK=1` to skip them; the banner then shows the LAN address and no reachability line.
-
-The first time Unsloth is published on a public URL (`--secure` or `--cloudflare`) with the auto-generated admin password still in place, it asks for a new admin password in the terminal (masked input with confirmation) before the public link goes up. Without an attached terminal it warns instead and keeps the bootstrap deadline: Unsloth shuts down after `UNSLOTH_STUDIO_BOOTSTRAP_TIMEOUT` (default 1 hour) unless the password is changed in the web UI.
-
-For headless setups that cannot answer that prompt, set the initial admin password non-interactively with `--password` (only takes effect when no password is set yet; if one already exists it is a hard error, so rotate later with `unsloth studio reset-password`):
-
-```bash
-unsloth studio --secure --password 'your-strong-password'        # visible in `ps`/history
-UNSLOTH_STUDIO_PASSWORD='your-strong-password' unsloth studio --secure   # via env var
-printf '%s\n' 'your-strong-password' | unsloth studio --secure --password -   # via stdin
-```
-
-A literal `--password VALUE` is visible in the process list and shell history, so prefer the `UNSLOTH_STUDIO_PASSWORD` env var or `--password -` (stdin) for automation. This applies to any launch (public or a headless `-H 0.0.0.0` bind), and the password is set in the parent before the server binds, so it never reaches a re-executed child process.
-
-Server-side tools (web search, Python and terminal code execution) run as your user and are on by default. Anyone who can reach the server with the API key can run code on this machine, so keep your API key private and pass `--disable-tools` when exposing Unsloth.
-
-#### Advanced launch options
-Installer options can be passed as environment variables. On macOS, Linux and WSL place the variable after the pipe so the shell passes it to `sh`; on Windows set it with `$env:` before piping to `iex`.
-
-Skip PyTorch (GGUF-only mode):
-```bash
-curl -fsSL https://unsloth.ai/install.sh | UNSLOTH_NO_TORCH=1 sh
-```
-```powershell
-$env:UNSLOTH_NO_TORCH=1; irm https://unsloth.ai/install.ps1 | iex
-```
-
-Skip the post-install prompt that starts Unsloth (useful for automated installs):
-```bash
-curl -fsSL https://unsloth.ai/install.sh | UNSLOTH_SKIP_AUTOSTART=1 sh
-```
-```powershell
-$env:UNSLOTH_SKIP_AUTOSTART=1; irm https://unsloth.ai/install.ps1 | iex
-```
-
-Pin the Python version:
-```bash
-curl -fsSL https://unsloth.ai/install.sh | UNSLOTH_PYTHON=3.12 sh
-```
-```powershell
-$env:UNSLOTH_PYTHON='3.12'; irm https://unsloth.ai/install.ps1 | iex
-```
-
-Install to a custom location with `UNSLOTH_STUDIO_HOME`:
-```bash
-curl -fsSL https://unsloth.ai/install.sh | UNSLOTH_STUDIO_HOME=/abs/path sh
-```
-```powershell
-$env:UNSLOTH_STUDIO_HOME='C:\path'; irm https://unsloth.ai/install.ps1 | iex
-```
-
-On macOS, the installer defaults to the system certificate store (`UV_SYSTEM_CERTS=1`) so uv trusts the CAs in your Keychain, needed behind TLS-inspecting proxies (Cisco Umbrella, Zscaler, etc.). Opt out with:
-```bash
-curl -fsSL https://unsloth.ai/install.sh | UV_SYSTEM_CERTS=0 sh
-```
-
-Point the frontend build at a corporate npm mirror/proxy with `UNSLOTH_NPM_REGISTRY` (for the developer install behind a firewall that blocks `registry.npmjs.org`):
-```bash
-UNSLOTH_NPM_REGISTRY=https://artifactory.example.com/api/npm/npm/ ./install.sh --local
-```
-```powershell
-$env:UNSLOTH_NPM_REGISTRY='https://artifactory.example.com/api/npm/npm/'; .\install.ps1 --local
-```
-It is threaded as `--registry` into the Unsloth frontend `npm`/`bun` installs; the supply-chain locks (7-day `min-release-age`, exact version pins) stay in force.
-
-Cap Unsloth's native CPU thread pools on high-core hosts: `UNSLOTH_CPU_THREADS=8 unsloth studio -p 8888`.
-
-#### Uninstall
-The recommended way to fully remove Unsloth Studio is the matching uninstall script for your OS. It stops any running servers, removes the install dir, the launcher data dir, the desktop shortcut, and any platform-specific entries (macOS `.app` bundle + Launch Services on Mac; Start Menu, `HKCU\Software\Unsloth` registry key and user `PATH` entries on Windows):
-
-* ​ **MacOS, WSL, Linux:** `curl -fsSL https://raw.githubusercontent.com/unslothai/unsloth/main/scripts/uninstall.sh | sh`
-* ​ **Windows (PowerShell):** `irm https://raw.githubusercontent.com/unslothai/unsloth/main/scripts/uninstall.ps1 | iex`
-
-If you only want to drop the install dir and keep the launcher/shortcut for a later reinstall, you can instead run `rm -rf ~/.unsloth/studio` (Mac/Linux/WSL) or `Remove-Item -Recurse -Force "$HOME\.unsloth\studio"` (Windows). The model cache at `~/.cache/huggingface` is not touched by any of these.
-
-For more info, [see our docs](https://unsloth.ai/docs/new/studio/install#uninstall).
-
-#### Deleting model files
-
-You can delete old model files either from the bin icon in model search or by removing the relevant cached model folder from the default Hugging Face cache directory. By default, HF uses:
-
-* ​ **MacOS, Linux, WSL:** `~/.cache/huggingface/hub/`
-* ​ **Windows:** `%USERPROFILE%\.cache\huggingface\hub\`

-"""Diff two `package-lock.json` files and flag NEW install-script deps.
-
-A `"hasInstallScript": true` package runs preinstall/install/postinstall
-hooks on every `npm ci` -- the lever behind recent npm supply-chain
-compromises (attacker publishes a malicious version of a trusted dep).
-This refuses to land a newly-introduced install-script dep without a
-maintainer eyeball; pre-existing ones are not re-flagged.
-
-Supports lockfileVersion 1 (recursive `dependencies`) and 2/3 (flat
-`packages` with `node_modules/.../node_modules/...` nesting). For each
-new entry we best-effort fetch the registry metadata to recover the
-postinstall command body; the finding is still emitted if unreachable.
-
-Exit codes: 0 = none; 1 = one or more (on stderr); 2 = internal error.

-# Enable ROCm-on-WSL for AMD GPUs (Strix Halo/Point APUs AND discrete Radeon RX
-# 7000/9000). Verified on gfx1151 (Radeon 8060S) and gfx1200 (Radeon RX 9060 XT).
-# ──────────────────────────────────────────────────────────────────────────────
-# install.sh routes the detected arch to the right ROCm wheels once a runtime exists;
-# what it does NOT do is install AMD's ROCm userspace + the WSL DXG bridge (librocdxg).
-# This helper does that Linux-side prerequisite on Ubuntu 24.04 WSL2, invoked by
-# install.sh when it sees an AMD GPU via /dev/dxg but no ROCm yet. Arch-agnostic: the
-# arch is auto-detected from rocminfo (override UNSLOTH_WSL_GFX=gfx1200). Idempotent.
-#
-# Manual, admin-gated Windows prerequisite: an AMD Adrenalin driver with
-# production ROCDXG/WSL support (26.2.2+). install.ps1 offers to update it. Once
-# installed + rebooted, /dev/dxg is exposed to WSL and this script builds the rest.
-#
-# HOW ROCDXG WORKS (and why older /usr/lib/wsl/lib notes are wrong): librocdxg.so
-# is AMD's user-mode bridge between the Linux HSA runtime and the Windows driver
-# over /dev/dxg. The STANDARD hsa-rocr runtime (NOT the gone "roc4wsl" package)
-# loads it when HSA_ENABLE_DXG_DETECTION=1. No hsa/rocm libs need injecting into
-# /usr/lib/wsl/lib (it holds only d3d12/dxcore), yet rocminfo enumerates gfx1151
-# fine -- so we gate on /dev/dxg, not on WSL lib injection.
-#
-# KNOWN CAVEAT (ROCm/ROCm#6022): librocdxg can cap usable ROCm VRAM at the WSL
-# VM's RAM (.wslconfig [wsl2] memory=) on some BIOS UMA layouts, and amd-smi
-# doesn't work in WSL. On OOM below capacity, raise memory= (then wsl --shutdown)
-# and watch GPU use from Windows. Large-UMA BIOS exposes the full pool regardless.
-#
-# Verified on Ryzen AI Max+ PRO 395 / Radeon 8060S (gfx1151) with ROCm 7.2.1 +
-# Ubuntu 24.04 + WSL2 + Adrenalin. These pins MOVE; bump + re-verify on newer ROCm.

-"""Measure where Unsloth Studio's startup time goes, per platform.
-
-Nothing measured this before: the backend logs "lifespan startup completed in X ms"
-but no test or CI job asserted a budget, and studio_test_kit discards the elapsed
-time of its /healthz poll. A first local run (Linux, warm cache, fast server CPU)
-found `import main` alone costs 6.6s before the server can bind, dominated by eager
-module-level imports pulled in by the `routes` package:
-
-    torch          1930 ms self
-    unsloth_zoo     914 ms self
-    routes          779 ms self
-    transformers    524 ms self
-
-Phases measured:
-  import   `python -X importtime -c "import main"`, top cumulative + per-package self
-  spawn    process start -> first byte on stdout
-  healthz  process start -> /api/health (or /healthz) answers 200
-  lifespan the backend's own "lifespan startup completed in X ms" log line
-
-Usage:
-    python scripts/profile_startup.py --repeats 3 --json out.json
-    python scripts/profile_startup.py --import-only     # no server, no port needed
-
-Exit code is 0 unless --max-healthz-seconds is given and exceeded.

-"""Keep `allowScripts` pins in studio/frontend/package.json in sync with
-package-lock.json.
-
-`npm approve-scripts` writes version-pinned entries ("pkg@1.2.3": true).
-A dependency bump strands the pin, so the approval (or denial) silently
-stops matching and the package's install scripts fall back to
-"unreviewed". This tool re-pins existing entries to the versions the
-lockfile actually resolves; it never adds or removes entries, so
-approving a brand-new script-bearing package stays a human decision.
-
-Usage:
-  python scripts/sync_allow_scripts_pins.py --check   # CI: exit 1 on drift
-  python scripts/sync_allow_scripts_pins.py --fix     # rewrite package.json
-
-Pinned keys follow npm's allowScripts grammar: "name@1.2.3" or
-"name@1.2.3 || 1.2.4". Bare names (no version) match every version and
-are left alone. Entries whose range is not an exact-version disjunction

-"""Deterministic comment / docstring-only verifier.
-
-Compares a list of changed files between two git refs and reports whether
-each diff is strictly comments / docstrings (Python) or comments
-(YAML / GitHub Actions). Useful for gating a "comment trim" /
-"docstring refactor" PR against accidental code drift.
-
-Per .py file: parse both revs into AST, strip module / class / function
-docstrings, then compare ast.unparse output. Pure Python comments are
-discarded by the parser by construction, so any post-strip diff is real
-code. Per .yml file: yaml.safe_load both sides and compare the parsed
-Python object; if scalar values differ, also strip shell comments inside
-``run: |`` block bodies before comparing. Exit code 0 = all OK, 1 = at
-least one file has a real (non-comment) diff or an error.
-
-Usage:
-    python scripts/verify_comment_only_diff.py [--base REF] [--head REF] path ...
-
-Defaults: --base origin/main, --head HEAD. Paths are repo-relative.
-
-Example:
-    git diff --name-only origin/main..HEAD \\
-      | xargs python scripts/verify_comment_only_diff.py --base origin/main

-"""Deterministic, scope-aware verifier for import-hoisting / alias-rename refactors.
-
-The risk when moving `from a import b as _b` (or `import b as _b`) to module top
-and normalizing `_b` -> `b` is twofold:
-
-  1. DANGLING ALIAS  - a `_b` reference is left un-normalized; it now resolves to
-     nothing (NameError) or, worse, to some *other* module-level `_b`.
-  2. RENAME CLASH    - `_b` was an alias on purpose because `b` already meant
-     something else in that scope; normalizing `_b` -> `b` silently re-points the
-     reference at the wrong object (no NameError, no pyflakes warning).
-
-This tool parses BEFORE (a git ref, default origin/main) and AFTER (default HEAD)
-for each file, builds a real LEGB scope model (functions, classes, lambdas,
-comprehensions, global/nonlocal, args, walrus, star-imports), and resolves every
-Name load to its binding. It then compares, PER SCOPE:
-
-  * UNRESOLVED-NEW   : loads that resolve to nothing in AFTER but did in BEFORE
-                       (or are newly present) -> catches dangling aliases.
-  * TARGET-MISSING   : an import *target* (e.g. module `glob`, or
-                       `importlib.metadata.version`) that a function resolved to
-                       in BEFORE but no longer resolves to in AFTER -> catches a
-                       function that lost access to a module it still uses.
-                       Robust to alias renames because it compares the *target*,
-                       not the local name.
-  * TARGET-CHANGED   : a load whose resolved import target differs BEFORE vs
-                       AFTER -> catches a rename that re-points to a different
-                       module (the clash case).
-  * AMBIGUOUS-BIND   : a name bound by BOTH an import and a non-import in the same
-                       scope in AFTER (and not in BEFORE) -> the "alias was on
-                       purpose / now collides" smell.
-  * MODULE-DUP-IMPORT: a module-level name imported and also defined/assigned at
-                       module level (introduced by the change).
-  * NEW-UNUSED-IMPORT: a module-level import added in AFTER that nothing resolves
-                       to (informational; re-exports are a known false positive).
-
-Usage:
-  verify_import_hoist.py [--before REF] [--after REF] <file>...   # compare
-  verify_import_hoist.py --self-test                              # prove it catches bugs
-Exit code 1 if any non-informational finding.

-# Unsloth Studio MCP server
-
-Unsloth can expose a local MCP server so an MCP client can inspect models and
-GPU state, validate recipes, start or stop training, inspect recipe output, and
-export a loaded model.
-
-The server is disabled by default. Enable it for a local Unsloth process with:
-
-```bash
-UNSLOTH_STUDIO_ENABLE_MCP=1 \
-UNSLOTH_STUDIO_MCP_TOKEN='use-a-local-secret' \
-unsloth studio
-```
-
-The endpoint is `http://127.0.0.1:8888/mcp/` when Unsloth uses its default port
-(a request to `/mcp` redirects to the canonical `/mcp/`). Use the actual Unsloth
-port when it is configured differently.
-
-The high-impact tools are:
-
-- `studio_status` and `list_local_models` for discovery
-- `get_training_status`, `start_training`, `stop_training`, and `list_training_runs`
-- `validate_recipe`, `get_recipe_job_status`, and `get_recipe_job_dataset`
-- `load_checkpoint` and `export_gguf`
-
-`start_training` accepts the same fields as the Unsloth `TrainingStartRequest`.
-The request is validated by the existing Pydantic model before a subprocess is
-started. Export paths use the existing Unsloth validation as well.
-
-The endpoint always requires `UNSLOTH_STUDIO_MCP_TOKEN` and checks an exact
-Bearer token for both HTTP and WebSocket connections. Keep it on localhost
-unless the deployment has an authenticated reverse proxy. The MCP endpoint is
-intentionally opt-in because tools can consume GPU memory, write model
-artifacts, and stop active work.

-  Unsloth-local changes vs PR #118:
-    1. preserve_thinking defaults to false (see SETUP block below).
-    2. The empty "<|channel>thought\n<channel|>" block on enable_thinking=false is
-       NOT emitted. Google ships a distinct template for E2B/E4B (google/gemma-4-E2B-it,

-       This file matches the E2B/E4B behavior; gemma-4.jinja keeps the larger-model one.

-  Gemma 4 chat template, vendored for Unsloth Studio.
-  Source: google/gemma-4-31B-it HF discussion/PR #118 (adds the preserve_thinking
-  flag plus null-rendering, string-arguments validation, balanced turn tags, empty
-  messages handling, and OpenAI image_url/input_audio aliases).
-  Unsloth-local change: preserve_thinking defaults to false (see SETUP block below).
-  Applied to unsloth/gemma-4-*-GGUF models so the embedded GGUF template does not
-  need re-downloading. Keep in sync with upstream if PR #118 changes.
