These are the site's own public files, as fetched, with the date. The robot reports what is published. It does not determine compliance, approval, or intent. A failed read is never a missing file.
Not checked: anything behind a login, account settings, or private feeds. Whether crawlers obey robots.txt. Business deals: a file line is not a contract.
