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.
