// tests/kb-update/test-priority-unverified.test.mjs
// TDD for carry-forward B (Sesjon 5): a reference file WITHOUT a "Last updated:"
// header must land in the 'unverified' priority bucket — not masquerade as
// critical-priority noise (the bug: dateless files got effectiveDate 0000-01-01
// AND a path-based priority, so they flooded the critical tier and drowned the
// genuinely-stale critical files).
//
// The decision lives in lag 0 (taxonomy.mjs makePriorityFn, the single source of
// truth for priority); report-changes only supplies whether the file carried a
// date header. The 'unverified' tier is declared in domain-taxonomy.json.
