  note: 'The MCP host runs on a separate registrable domain from sweep.io and inherits none of sweep.io''s
    posture: no CAA, no DNSSEC, no SPF, no DMARC, and no HSTS header on the OAuth metadata response. sweep.io
    itself is p=reject with CAA pinning and an iodef security contact.'
notes: Two registrable domains are in play. sweep.io publishes SPF, DMARC p=reject, CAA including iodef
  mailto:security@sweep.io, and HSTS on www; it does not sign DNSSEC. sweepmcp.com — which serves the
  OAuth-protected MCP endpoint an agent actually calls — publishes none of these.
