Nine are old page addresses and seven are WordPress short links (?p= and ?page_id=). A redirect that points at another redirect stops this site's build, so the count of chains stays at zero.

Technical SEO problems pile up before anyone sees them

Crawl paths, indexation rules, rendering behavior, and internal links all interact, often in ways that aren't obvious until scale or change is introduced. I've watched sites lose thousands of indexed pages after a platform migration because nobody mapped the old URL patterns to the new ones. I've seen render-dependent content vanish from Google's index because the JavaScript that loaded it failed silently on Googlebot.

Technical SEO problems rarely announce themselves. They compound silently until something breaks visibly.
