Check the permanent redirects under [[Special:PrefixIndex/User:AnomieBOT/req/|User:AnomieBOT/req/]] to validate the anchor still exists in the target page. If the anchor can be found in an archive subpage, the redirect will be updated. Otherwise, the bot will ask for help on its talk page.
 
Note this doesn't handle {{tl|archiveanchor}} or the like, just TOC headers.
