- pyproject [tool.ruff.lint]: ignore RUF022/RUF023 (deliberately grouped __all__/__slots__), SIM117, BLE001 (blind except is intentional at CFFI callback boundaries) - Legit fixes: dict/tuple instead of typing.Dict/Tuple in generate.py, unquoted annotations in raf.py, Self return for __enter__ methods, explicit check=False on subprocess.run, collapsed nested ifs, sorted test imports, unused-unpacked-variable in test_raises - Bump minimum versions to the synced toolchain: cffi 2.1.1, ruff 0.16.10, pytest 9.1.1, auditwheel 6.8.2, setuptools 84.0.0, setuptools-scm 10.3.4 (project deps and build-system requires)
