+- Include concrete facts, measurements, dates, comparisons, and examples when available.
+- Explain why the evidence matters: discuss implications, tradeoffs, limitations, and practical

+- Compare sources and account for counterevidence or conflicting findings in the relevant section.
+- Prefer useful depth over brevity, but avoid repetition, filler, and unsupported speculation.
+- Cite factual claims where they appear using exactly `[Source Title](exact URL)`.
+- Use only titles and URLs from the source catalog. Never use bare URLs, numeric citations,

+streams keep-alives while waiting, releases on completion, and maps rejects to
+429/503. Slot occupancy is driven directly through the shared queue (keyed by the
+backend base_url) so generation stays fast and no thread has to block.

+"""Numerics + gating for the RDNA4 _grouped_mm CPU fallback (PRs #7276 / #7292).
+
+RDNA4 (gfx1200/gfx1201) ships a null HIP `_grouped_mm` kernel on ROCm <= 7.12
+(fixed in 7.13, ROCm/TheRock #5284). Training MoE models there crashes with
+0xC0000005 on Windows and a plain segfault on Linux, so worker.py registers a
+Python mm/bmm fallback on the CUDA dispatch key.
+
+The fallback is silent, GPU-gated, and reimplements a matmul: if it is wrong, an
+RX 9070 user does not crash, they train on quietly wrong gradients. Until now the
+only coverage was `assert '_gm_lib.impl("_grouped_mm"' in source` -- the math was
+never executed once, in any suite.
+
+worker.py cannot be imported here (module-level structlog/backend imports), so
+`_install_grouped_mm_cpu_fallback` is lifted out with ast and driven with a fake
+`torch_mod` that forwards to real CPU torch. That also pins the op surface: the
+fallback may only use the ops the fake exposes, and the registration is captured
+instead of hitting a real CUDA dispatch key that CI runners do not have.
+
+The two gates around it are exec'd straight out of the source so this file tests
+the shipped expressions rather than a copy of them.

+"""Regression tests for the Colab "OutStream has no attribute 'watch_fd_thread'"
+startup crash.
+
+Field report (Colab): Unsloth Studio dies at server startup with
+``❌ Unsloth Studio failed to start: 'OutStream' object has no attribute
+'watch_fd_thread'``.
+
+Root cause chain:
+ * Colab's ipykernel ``OutStream`` is created with ``watchfd=False``, so it
+ never gains a ``watch_fd_thread``; the ``OutStream.close()`` shipped in the
+ affected ipykernel versions joins that thread unconditionally and raises
+ ``AttributeError`` (ipython/ipykernel#867).
+ * ``run._setup_server_disk_logging()`` replaces ``sys.stdout``/``sys.stderr``
+ with a ``_TeeStream``. That changes the console object identity, so Colab's
+ ``absl`` logging handler -- which captured the ORIGINAL OutStream and whose
+ ``close()`` deliberately skips ``sys.stdout``/``sys.stderr`` -- no longer
+ recognizes it as the live console.
+ * ``run_server`` builds ``uvicorn.Config(...)``, whose ``configure_logging`` ->
+ ``logging.config.dictConfig`` -> ``logging.shutdown`` closes every existing
+ handler. The absl handler then calls ``OutStream.close()`` on the orphaned
+ stream, and the AttributeError aborts startup.
+
+These tests reproduce the mechanism with a stand-in OutStream (Colab-identical
+constructs are not importable off Colab) and assert the tee/console path used at
+startup survives it.

+"""GRPO smoke test for the ``fast_inference=True`` vLLM rollout path.

+Exercises the vLLM LoRA activation path (`WorkerLoRAManager`) that regressed on
+vLLM >= 0.25.0 (unsloth#7283): the stacked `WeightsMapper` collapsed q/k/v and
+gate/up LoRA weights onto one key, crashing adapter activation with
+`IndexError`. All seven attention and MLP projections are LoRA targets so both
+the fused `qkv_proj` and `gate_up_proj` families are covered.
+
+Kept deliberately tiny so it finishes in well under a minute: a 0.6B model,
+`enforce_eager`, no torch.compile, three short training steps, and short
+prompts/completions. Seeded, so the asserted metrics are reproducible.
+
+Run directly (`python tests/fast_inference/test_fast_inference.py`) or via

+Every copy carries a "kept in sync with" comment and nothing enforced it, which is

+generic rocm7.2 index), #7293 / #7300 (fixed in one installer at a time) and #7277
+(RDNA2 gfx1030-1036 added to install.ps1 / setup.ps1 / install_python_stack.py --
+install.sh had to follow separately). Half-applied edits are invisible until an AMD
+user on the missed path gets CPU-only PyTorch.
+
+These tests parse each copy out of its source file and compare them, so a table
+edited in one place fails CI naming the file that was missed.
+
+Counting the copies by hand is itself unreliable -- the in-code "kept in sync
+with" comments claimed four when there were seven -- so TestNoUnregisteredArchTable

+"""Coverage for the native-Linux system-ROCm library prepend (PR #7233).
+
+#7233 fixed the segfault-on-launch class of AMD reports (#7208, #7310, #6276 and
+the native-Linux half of #7307): a prebuilt llama.cpp ships its own libggml-hip /
+HIP runtime, and on a bare-metal ROCm box that bundled runtime can disagree with
+the host amdkfd driver, so the server dies the moment a model is loaded. The fix
+prepends the *system* ROCm lib dirs ahead of the bundle on LD_LIBRARY_PATH.
+
+It landed as two hand-copied helpers, one in the installer (validation-time) and
+one in the serve-time launcher:
+
+ studio/install_llama_prebuilt.py _bundled_hip_present / _native_linux_system_rocm_lib_dirs
+ studio/backend/core/inference/llama_cpp.py same two, "mirrors" comment only
+
+and shipped with no tests at all: the WSL sibling helper added earlier has
+TestWslSystemRocmLibDirs / TestBinaryEnvWslOrdering / TestLlamaCppRuntimeWslOrdering,
+the native-Linux one has nothing. Every gate here is a false-positive risk that
+would silently reorder LD_LIBRARY_PATH for users the fix was never meant to touch
+(WSL, NVIDIA hosts, macOS, containers without /dev/kfd), so each gate gets a test,
+and both copies are run against the same fake host and required to agree.
+
+llama_cpp.py cannot be imported from the test suite (module-level structlog /
+backend imports), so its two helpers are lifted out with ast and exec'd standalone.

+"""Regression tests for what ``_get_new_mapper`` hands back to the upgrade probe.
+
+``test_new_mapper_no_global_leak.py`` serves the repo's own ``mapper.py`` as both installed
+and fetched source, so it cannot tell a fetched table from a fresh copy of the installed one.
+Two gaps it misses:
+
+1. The probe must answer for an fp8 repo only the FETCHED mapper knows, so an extra ``"8"``

+"""Regression test for ``_get_new_mapper`` leaking into ``loader_utils`` globals.
+
+``get_model_name`` calls ``_get_new_mapper()`` whenever a name misses the local
+tables, purely to answer "would a newer Unsloth support this?". It fetches
+``mapper.py`` from GitHub main, prefixes the three mappers it wants with
+``NEW_``, and ``exec``s the result into ``globals()``.
+
+The slice starts at ``__INT_TO_FLOAT_MAPPER``, so it also carries
+``FLOAT_TO_FP8_BLOCK_MAPPER``/``FLOAT_TO_FP8_ROW_MAPPER`` and the two
+``_add_*`` helpers, and those names are NOT renamed. Exec'ing into
+``globals()`` therefore rebinds the FP8 tables that ``loader_utils`` imported
+from the installed ``mapper``, so every later ``get_model_name(...,
+load_in_fp8 = ...)`` in the process resolves through GitHub main's table
+instead of the installed one. The probe is supposed to read, not to swap the
+installed mappings out from under the caller.
+
+``loader_utils`` imports torch, so ast-extract ``_get_new_mapper`` and run it

+"""Guard: shipping code must name an encoding on every text read and write.
+
+`Path.read_text()`, `Path.write_text()`, `Path.open()` and builtin `open()` fall back
+to `locale.getencoding()`: UTF-8 on the Linux and macOS runners, cp1252 on a stock
+Windows install. Every file this repo reads at runtime is UTF-8 (HF `config.json` /
+`tokenizer_config.json` / `adapter_config.json`, Ollama manifests, GGUF export
+metadata), so on Windows those reads crash or, worse, succeed with mojibake: a
+DeepSeek or Qwen tokenizer_config.json carries U+FF5C and U+2581 in its chat
+template, and at utils/models/model_config.py that read sits inside a broad
+`except Exception: logger.debug(...)`, so the token-pattern check silently
+returned the wrong answer.
+
+Unlike the import-time rule in test_source_read_encoding.py this is scope agnostic:
+runtime reads live inside functions, and shipping code has no legitimate reason to
+let the operator's locale decide. No reachability analysis to get wrong, so no
+allowlist and no false positives.
+
+Binary handles are skipped (no encoding to name, and passing one is a ValueError),
+and a non-constant mode counts as unknown rather than text: demanding `encoding =`
+on a call that may resolve to "rb" would leave no compliant way to write it.
+
+Known limitation, deliberately not closed: `configparser.ConfigParser.read()` also
+defaults to the locale encoding, but cannot be matched by name without resolving the
+receiver, since `f.read(n)`, `resp.read(limit)` and `handle.read(chunk)` are spelled
+identically. Flagging it would be a false positive with no compliant fix, the exact
+failure mode this guard avoids. The one live `ConfigParser.read` (/etc/wsl.conf,
+hub/utils/paths.py) is pinned by hand; a future one has to be caught in review.

+"""Guard: tests that read checked-in files must name their encoding.
+
+`Path.read_text()` and `open()` with no encoding use `locale.getencoding()`:
+UTF-8 on the Linux and macOS runners, cp1252 on a stock Windows install. A test
+that reads a repo file that way passes in CI and raises UnicodeDecodeError for a
+Windows contributor as soon as that file gains a non-ASCII byte, which the
+source-scanning tests do constantly:
+
+ studio/backend/routes/inference.py carries the DeepSeek tool-call token
+ regexes, so it holds U+FF5C and U+2581. Reading it as cp1252 dies on
+ "byte 0x81", taking test_cancel_atomicity.py and test_cancel_id_wiring.py
+ out at collection time.
+
+A call is an offence when it does un-pinned text I/O and either of two things
+holds. It runs at import, where nothing can see a tmp_path fixture yet. Or the
+path it reads anchors on something checked in: a module-level constant or
+import, which a fixture parameter can never be, `__file__`, or a relative
+literal that names a file actually present in the tree. Anchoring is what
+decides the second one, followed through `/` joins, path methods, the locals
+and loop variables of the enclosing function, and the parameters of helpers
+every caller hands a checked-in path. So `for p in (_B / "routes").rglob("*.py")`
+is in scope, `_source(LOADER_PATH)` puts the bare read inside `_source` in
+scope, and anything growing out of a tmp_path stays out. That reaches test
+bodies, where the same failure lands one step later:
+
+ test_gemma4_chat_template.py opens unsloth/chat_templates.py through a
+ helper its tests call, and cp1252 cannot decode that file ("byte 0x90").
+ test_consent_gate.py reads routes/inference.py as `(_BACKEND / rel)` and
+ test_gguf_load_cache_reuse.py as `Path(__file__).parent.parent / ...`, both
+ dying on the same 0x81 the two cancel modules hit at collection.
+
+Every question the rules ask is answered by the call, its path expression, or
+the call sites of the helper it sits in, which keeps them mechanical enough to
+enforce with no allowlist and quiet about temp-dir I/O, where the platform
+default is harmless and the test wrote the bytes itself.
+
+Three shapes are consequently out of reach, all fixed by hand and none decidable
+from the call. A path a helper hands back rather than takes in, as
+`for path in _iter_caller_files()` does in test_security_gate_consistency.py,
+says nothing about itself at the read. Text read from a checked-in file and
+then written back to a tmp_path, at test_studio_install_workspace_guard.py:851
+and test_scan_packages.py:40, is unsafe only because of where the string came
+from. And a read inside a `python -c` snippet, as test_studio_import_no_torch.py
+and test_e2e_no_torch_sandbox.py build for their subprocess tests, runs in a
+child interpreter this scan never parses: the snippet is an f-string whose paths
+are replacement fields, so recovering it would mean evaluating the
+interpolation. Reviewers have to catch those three; running the suite under
+LC_ALL=C is the cheapest way to find them, since ASCII rejects every byte cp1252
+does and more.
