// Sibling test for c32_real_tests.ts. buildLiveTestData fans out to
// loadTestBundle + fetchRepoCommits (both network/disk) so the
// end-to-end is covered by the live /reports/live/tests route. The
// pure helpers — agent attribution and the file/name label shortener —
// are unit-testable here.
