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.
