// tests/kb-update/test-backfill-status.test.mjs
// TDD for the Status-backfill mechanism (R21 + Enhet 3). The applier (backfill-status.mjs)
// is a manifest-driven driver over the already-tested insertMetaField primitive; the ONLY
// new production logic is the pure deterministic value rule statusForFile() + the frozen
// MANIFEST. This suite pins both:
//   - statusForFile: filename token (template|matrix|benchmarks|register) → 'Reference',
//     else 'Established Practice'. Operator-approved vocabulary (2026-07-06).
//   - MANIFEST self-consistency: distinct entries, each value === statusForFile(path).
//
// Scope history:
//   R21 (2026-07-06)   — 14 English-dialect advisor/architecture files (7 Reference + 7 EP).
//   Enhet 3 (2026-07-07) — +25 non-advisor "none"-dialect files that lack **Status:** entirely
//     (ground-truth measured: 25, NOT the roadmap's "27" — 2 of the roadmap count were files
//     whose bold **Status:** sits past byte 500, i.e. present-but-header-invisible, a separate
//     header-slanking residual, not a missing-Status file). None of the 25 match the artifact
//     token → all 'Established Practice'. The 4 dual-header ai-act-* files are handled by the
//     plain→bold dedup driver (dedup-plain-header.mjs), NOT here — they carry an authored
//     `Status: GA` we preserve, so they must stay OUT of this derive-a-value manifest.
