Linked documents are reported inside A11y Gate's entry panel. The gate reads
a page's rendered HTML and cannot open a linked PDF, so an entry linking to an
untagged document read as passing there while this addon refused the same save.
Two addons giving an author opposite answers on one screen is worse than either
being absent.

The block lists the documents an entry links to, names what is wrong in the same
words the dashboard and the queue use, and links to the remediation queue. Its
tone is error only when a finding is critical, so its colour means what the
gate's does. It says so when the documents have never been checked, because
silence there reads as "checked, and fine".

Registered only when A11y Gate is installed. Upgrading re-checks nothing.
