Agent access & discovery signals
Optional and unscored — it never changes the grade. Reads up to three public files from this site (robots.txt, llms.txt and /.well-known/security.txt) and reuses the homepage headers already fetched. llms.txt is an emerging proposal, not an official standard. It is informational and does not affect the grade.
