description: >-
  Results of probing the /.well-known/ discovery surface on https://crob.at, the
  only host apis.yml and the OpenAPI servers[] name. crob.at serves a real RFC
  9727 api-catalog linkset, an APIs.json index (also aliased at /apis.json), and
  an APIs Onboarding (aod 0.1) document; robots.txt carries a Content-Signal
  line (search=yes, ai-train=no, ai-input=yes). 404 paths return the site's
  HTML shell with a real 404 status code. Agent-card probes (both the canonical
  and legacy paths) missed, so no AgentCard pointer is emitted.
