description: >-
  Probe of the standard /.well-known/ discovery surface across Synadia's marketing host, docs host,
  Synadia Cloud console host and the NGS HTTP Gateway API host. www.synadia.com serves a real
  RFC 9727 api-catalog linkset and an Agent Skills registry index; both are saved verbatim. All other
  standard paths return 404 on that host (the Astro site answers unknown paths with a 404-status HTML
  page, so the byte size is non-zero but the status is a true 404). The Cloud console and NGS hosts
  answer 404 text/plain on every well-known path.

      It does NOT link an OpenAPI; both machine-readable contracts were found elsewhere.
