 ## Conventions
 - **Changelogs**: Every user-facing change MUST have a changelog entry before opening a PR. Run `npm run changelog` (entries stored in `changelog/`).
-- **Test assertions**: When a single test has multiple assertions, pass a message as the third argument to each assertion (e.g., `self::assertSame( $expected, $actual, 'Foo should be updated.' );`) so a failure points to the specific check that failed.
