// instead: `scripts/lint-test-file-count.allowlist.json`'s `milestone` entry
// is an IDENTITY ratchet (an exact, already-over-cap list of 8 known
// filenames) — a new `milestone-archive.security.test.cjs` buckets into the
// same `milestone` module (`testEffectivePrefix` strips `.test.cjs`, and
// `milestone-archive.security` still starts with `milestone-`) and is a
// NOVEL file the ratchet has never seen, so `node scripts/lint-test-file-count.cjs`
// fails it outright (verified empirically: FAIL_NOVEL_FILES, exit 1).
// Splitting this describe block out is blocked by that ratchet, not by
