* [What qualifies as a bug fix?](./bug-fix-procedure.md#what-qualifies-as-a-bug-fix)

## Exemptions

Even if some of our infrastructure can be used by others, it is still considered
internal and comes without stability guarantees.
This is a non-exhaustive list of components without stability guarantees:

* The CLIs and environment variables used by `remote-test-client` / `remote-test-server`
