A-165 callers: the tool runner refuses a seat verb's caller outside its effective callers before the bundle

Browse Source 
Where serveSeats answers a seat's verb it reads the verb from the runner's seat list (seatdef's
EffectiveCallers): an unproven caller is refused, and every caller while the seat's definition is unread,
names no such verb or opens it to none; a proven caller is among them, since the grants part composes the
call subject only for the effective callers. A module's tool on the subject naming no caller is unchanged.

Builds: design 47 G §610; lead answers A-165, A-179
