 * GOV-01 / SW-RR-03. Structural gates for facts that a hand-maintained document
 * cannot keep true.
 *
 * The adapter review inventory claimed 118/118 while the tree held 119 files,
 * so a whole adapter was outside every review's coverage without anything
 * failing. And the Service Worker asset generator and the shared manifest
 * decoder each carried their own extension table, so a build could emit an
 * asset the runtime contract then refused. Both are now equalities this script
 * checks rather than numbers someone has to remember to update.
