Web pages saved as HTML

The axe-core rules our page scanner runs, filed under the same WCAG criteria. The file is rendered in a sandboxed frame where its own scripts don't run; the signed-in Document Audit also runs them, with the scanner's own checks.

Every WCAG 2.2 A and AA criterion

Each criterion is marked failed, needs review, no issues found, manual check or not applicable, so nothing reads as passed that wasn't checked. Level AAA findings are shown for information.
