Methodology
Dismissed. is a forensic catalog, not an opinion column. Every entry traces back to a real line of code. Here's exactly how a notice gets booked and scored.
Enumerate the callbacks
We install each plugin and use WP-CLI + PHP Reflection to dump every callback hooked to admin_notices, all_admin_notices, and network_admin_notices — resolving each closure back to its file and line.
Check for a screen gate
A well-behaved notice checks get_current_screen() and only renders on its own pages. We render each callback under several unrelated screens; one that shows up everywhere has no gate — it hijacks the whole dashboard, and the count goes up.
Capture & recreate the render
Each notice's live HTML is captured and faithfully recreated in the wp-admin canvas you see on every artifact — same markup, same severity border, same missing dismiss button.
