description: >-
  Probe of standard /.well-known/ discovery endpoints across Terrastruct's
  public hosts. No well-known documents are published — terrastruct.com returns
  404 for every probed path, and d2lang.com (an S3-hosted static docs site)
  returns 403/AccessDenied for all paths. Absence is a valid, recorded result.
