  Every /.well-known/ path below was probed anonymously on 2026-08-09 and returned 404. The origin
  returns a genuine 404 for unknown paths — verified with a control probe to
  https://centrexion.com/llms-nonsense-xyz123.txt, which returned an nginx 404 body (146 bytes)
  rather than a soft-200 catch-all. No document was saved because none exists; an absent record is
  valid recorded data, not a failed probe. Note that the same control confirms the site's /llms.txt
  is a REAL 200 and not a catch-all artefact — it is saved verbatim at
  llms/centrexion-therapeutics-llms.txt.
