scripts/format.mjs skips *.test.mjs during runtime discovery, so a test added under a discovered root is never seen by format:check until it is listed in scripts/format-scope.json — which is what CODE-BOUNDARIES.md means by adding tests to the explicit list as they are adopted. The file went in unformatted and the check stayed green, hiding it. Listed and formatted; format:check now covers 917 files instead of 916.
