Orphan test page
Why this page exists
This page is listed in the XML sitemap, but no other page on the site links to it. A crawler that builds an internal-link graph should find zero internal links pointing here, while still being able to fetch the page from the sitemap. That is the classic orphan-page condition, and it is planted here so the software can be checked against a known answer.
What a correct result looks like
The page is observed with status 200, it is indexable, its canonical points to itself, and the count of internal links pointing to it is zero.
