summary:
  strong:
  - DNSSEC signed on both registrable domains
  - HSTS with includeSubDomains and preload on both apex domains
  - TLS 1.3 everywhere with valid chains
  - CAA issue restrictions plus an iodef incident-reporting address
  - SPF and enforced DMARC on both domains
  gaps:
  - DMARC policy is p=quarantine, not p=reject
  - No HSTS on the status.jerry.ai GitHub Pages host
  - No /.well-known/security.txt on any host (see jerry-vulnerability-disclosure.yml)
