Sitemap and canonical URL
Is there a valid sitemap, and does the page declare which address is the real one?
Why it matters
Agents deduplicate by canonical URL. Without one, the same page reached through three paths becomes three sources that can disagree, and a citation may point at the copy you did not want indexed.
How to fix it
Publish a valid sitemap.xml, reference it from robots.txt, and put a self-referencing <link rel="canonical"> on every page.
