Archive Freshness Audit
Freshness of all 448 archives measured against the snapshot date 2026-09-17: 438 carry updatedOn within 30 days, no archive falls in the 31–180 day bands, and 10 have no update record. Every dated entry falls inside the ten-day window 2026-09-06 → 2026-09-17, so this audit reports snapshot completeness rather than time trends.

Freshness buckets
Archive count per freshness bucket; the whole dated population sits in the 0–30 day bucket.
Method
- Population: all 448 archives in data/tools; freshness is computed from each archive's updatedOn field only.
- Buckets: 0–30, 31–90, 91–180 and 180+ days before the snapshot date (the latest updatedOn in the library, 2026-09-17); archives without updatedOn form the "no record" bucket.
- Window fact: all 438 dated records fall between 2026-09-06 and 2026-09-17 — a ten-day snapshot window — so no time-trend claims are made on this page.
