which edition · when checked · what moves
A citation on a row says where a number came from. This page answers the other two questions: when a human last checked it is still true, and what in this manual moves if the body republishes. Detection is partial — a body that swaps a revised PDF in at the same URL is invisible to any check here, which is why every row carries a review interval, and why this page only ever reports no change detected — never an all-clear.
