Log every 404 hit with referrer, user-agent and hit-count, then redirect the top offenders to the right live URL without leaving wp-admin. No FTP, no .htaccess edits, no lost link-equity.
The exact path hit, query string preserved for debugging.
Internal, external, direct — grouped so you spot bad internal links fast.
Bot vs human split, so Googlebot 404s get triaged before human ones.
Sorted by frequency; a 404 hit once a month is noise, one hit 400× is a bleed.
Every logged 404 has a 'Redirect to…' picker inline: type or search a live URL, pick 301 / 302 / 307, save. The redirect is created in the same table the Redirections module reads from, so it's live immediately with no cache flush.
Filter out common bot-noise 404s (wp-login probes, /xmlrpc.php, /.env sniffers) so the dashboard shows real editorial gaps, not attack surface.
