-- **Design before you write.** Answer four questions first: what is the module
-  for, what is its I/O contract, what failure am I guarding against, and what is
-  the cheapest level that catches it (unit over integration over e2e)?
-- **Reuse before create.** Extend existing test files, `conftest.py` fixtures, and
-  helpers; add a new file only when no nearby suite fits.
-- **Test behavior with intent.** Assert observable outcomes through public APIs;
-  state why in the name or docstring. Skip trivial wiring; flaky tests are worse
-  than no tests.
-- **Keep it minimal.** One behavior per test and the smallest setup that
-  triggers it; if the test diff dwarfs the code change, cut scope.
-- **No one-off kernel benchmarks in `tests/`.** Put kernel perf work in
-  `benchmarks/kernels/`; prove correctness in existing pytest suites.
-- **Run model evals for model-affecting changes.** Search `tests/evals/` or use
-  `vllm bench` and include results in the PR — do not wait for reviewers to ask.
