  Probed /.well-known/ discovery surface across the MX hosts (api.mx.com,
  www.mx.com, docs.mx.com). Only the RFC 9116 security.txt (PGP-signed, served
  from www.mx.com with canonical https://mx.com/.well-known/security.txt) was
  present. The api.mx.com host returns HTTP 400 to bare well-known and
  /openapi.json probes (auth-gated API host, no anonymous discovery surface);
  the machine-readable spec is published at
  https://docs.mx.com/openapi/platform-api/v20250224.yaml instead.
