note: >-
  Every /.well-known/* path on three.arcprize.org returns HTTP 200 but with
  content-type text/html — the single-page-app catch-all shell, not a genuine
  well-known document. Treated as NOT PRESENT (no authentic artifact saved).
  arcprize.org and docs.arcprize.org return 404 for all probed paths.
