⚠️ This page is noindex — but you cannot see it in View Source
HTML source : NO <meta name="robots"> tag ← looks fine
HTTP header : X-Robots-Tag: noindex ← invisible without DevTools
Sitemap lists : /pdf-report.html ← contradiction
To verify: open DevTools → Network tab → reload → click this request →
check Response Headers for X-Robots-Tag: noindex.
This is an internal report page. The server sets X-Robots-Tag: noindex
via the _headers file — but there is no noindex meta tag in this HTML.
This is the "alt" variant: noindex via HTTP header, not via HTML meta tag.
The fix is the same — remove this URL from the sitemap.
