1//! CSV storage for test results. The schema is a header line followed by rows:
2//! `suite,name,category,status,duration_ms,timestamp,commit,note`. `suite` is one
3//! of `protocol`/`unit`/`system`; `status` is `pass`/`fail`/`skip`/`unknown`;
4//! `commit` is the changeset the test last passed at (empty when not passing);
5//! `note` explains a skip/fail reason (empty otherwise).
