source: live GET of the named /.well-known/ path list on every host this record knows
note: >-
  Probed the registrable domain (dremio.com + www), the docs host, the Dremio Cloud API host
  (api.dremio.cloud), the hosted MCP host (mcp.dremio.cloud) and the authorization server host
  named in the MCP protected-resource document (login.dremio.cloud). Real documents were served
  on three of the six hosts. Every host carried a negative-control probe at a path that cannot
  exist; all six returned a non-2xx, so no path-echoing host is in this set.

  note: >-
    /.well-known/agent-card.json and the legacy /.well-known/agent.json returned 404 on all six
    hosts. No a2a/ artifact was written — an agent card is search-only and is never authored on a
    provider's behalf.
