Canonical test page

Why this page exists

This page is served normally, but its canonical link element names the crawl test guide as the preferred version instead of naming itself. A crawler should record the canonical exactly as declared and notice that it does not match the page address.

What a correct result looks like

The page is observed with status 200 and the canonical recorded for it is the guide address. The software should treat this as a canonical mismatch, not as a duplicate it invented.
