-Use `unittest.mock.patch` / `MagicMock` to mock dependencies and isolate the logic under test. If the module fails to import on CPU CI (e.g., imports `torch` or CUDA ops at module level), use `sys.modules` stubs to make the import succeed. See existing tests in `test/registered/unit/` for examples.
+Use `unittest.mock.patch` / `MagicMock` to mock dependencies and isolate the logic under test. If the module transitively imports GPU-only packages (e.g. `sgl_kernel`), they can be stubbed so the test runs on CPU CI. See `test/registered/unit/README.md` for details and examples.

 **Quality bar** — test real logic (validation boundaries, state transitions, error paths, branching, etc.). Skip tests that just verify Python itself works (e.g., "does calling an abstract method raise `NotImplementedError`?", "does a dataclass store the field I assigned?"). Consolidate repetitive patterns into parameterized tests. No production code changes in test PRs.
