Eight lists of seat verbs (checker, enrolment, artifact sweep, delivery, node-resolver, node-nfs-server, node-mounts, mesh-config's input) and their schema helpers were read by nothing but one test, and drifted from their seats (B0's verb input never reached the checker's copy). A guard row in the seats test finds any list of the catalogue's verbs written in the node-engine's code. Claude-Session: https://claude.ai/code/session_01NcbgfFSnn24M3GcqttoU7i
