The controller ended (ADR 0590): the grants issued are the grants part's alone, so its grant value
is Grant and GrantSource goes; a node trusts the vault's key alone, follows the grants part's
user list alone and composes its own or none; the controller's composed and builds bucket names
go. nox calls seat verbs (ADR 0590 clause 7), so the cli package that spoke to the node-engine's
socket goes, and mesh-hand-compose, which wrote the controller's compositions. A have an engine
from before wrote, composes controller, still reads. Issue 1126 B4a, B6.
