What to fix
- security.txt is missing the Expires line, which RFC 9116 requires. Guide
- robots.txt tells ChatGPT-User not to open pages for users; if that is unintended, split training crawlers from assistants. Rules for AI crawlers
- No HSTS header: browsers can still be downgraded to HTTP on the first visit.
- No privacy policy link found on the homepage. Legal notices checklist
- No accessibility statement link found on the homepage. Legal notices checklist
- No llms.txt: a short Markdown index of what the site offers to AI assistants. Guide
- No A2A agent card at /.well-known/agent-card.json. Guide
