The UAP sightings layer is sourced from a live scrape of nuforc.org with a
static Hugging Face CSV mirror (kcimc/NUFORC) as a fallback. The fallback
parsed every row, sorted by occurred-desc, and took the top 250 — with no
date cutoff. The HF mirror is a third-party snapshot that hasn't been
refreshed in years, so the "newest 250" rows it returns are from ~2022-23.
When the live path fails (Cloudflare 403, curl disabled on Windows, wdtNonce
regex stale, etc.) users see a map full of sightings from 3 years ago,
labeled as the "last 60 days" layer.
Changes:
* HF fallback now applies the same 60-day cutoff the live path uses. Rows
outside the window are dropped before take-top-N. If the mirror has
nothing inside the window the fallback returns [] (don't serve stale).
* When the HF mirror is fully stale a loud ERROR log fires with the count
of dropped rows so the operator can tell the mirror's the problem, not
a network issue.
* When BOTH live AND HF fallback produce 0 rows, fetch_uap_sightings now
trips assert_canary("uap_sightings", 0) so the health registry shows
the layer as broken instead of "fresh and empty for days."
* Scheduler moved from daily 12:00 UTC to weekly Mondays 12:00 UTC. The
layer is a rolling 60-day digest; refreshing once a week is enough
cadence for human-readable map exploration and keeps nuforc.org load
light.
6 new tests cover the cutoff filter, the doomsday-log path, the mixed-age
path, the both-paths-empty health failure, the positive fallback path, and
the scheduler cadence.
