What to fix

  1. No robots.txt is served, so every crawler applies its own defaults. Rules for AI crawlers
  2. No HSTS header: browsers can still be downgraded to HTTP on the first visit.
  3. No accessibility statement link found on the homepage. Legal notices checklist
  4. No llms.txt: a short Markdown index of what the site offers to AI assistants. Guide
  5. No A2A agent card at /.well-known/agent-card.json. Guide
