The seat list's verbs saying `chunks: true` (ChunkVerbsOf, as KeptEventsOf) give the principal that answers the verb (a module's
own account for a seat it holds, the tool runner's for a carried module's) the publish of the chunk subjects and the
subscription to the acks, and an account naming the verb by name in `invokes` the reverse; a `*` entry none. The bus module's
keeper holds a standing grant of the restore subjects of the restricted streams, and only those.
