  Only hosts Harbinger Health actually controls are recorded. The upstream documentation hosts
  referenced from apis.yml humanURL fields (developer.wordpress.org, modelcontextprotocol.io) are
  third-party and are deliberately excluded so their posture is not attributed to this provider.

      Fronted by Cloudflare (server: cloudflare). No Strict-Transport-Security header was returned
      on any probed path, so HSTS is not asserted for this origin.

findings:
  strengths:
    - TLS 1.3 negotiated on the only production host.
    - DNSSEC is signed on harbinger-health.com.
    - Both SPF and DMARC records are published.
  gaps:
    - No HSTS header, so the origin does not pin browsers or agents to HTTPS.
    - No CAA record, so any public CA may issue for the domain.
    - 'DMARC policy is p=none: reporting only, nothing is quarantined or rejected.'
    - No /.well-known/security.txt (RFC 9116) is served.
