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.

ADR 0582 clause 3 writes the key holder "with the why, the ask and the time": LeaseHolder gains ask and at,
which LeaseHandedAway ignores (it reads handed-to alone). The grants part's user-list key gains lease-handed,
so the bus node's engine follows the grants part's list alone once the lease is handed (ADR 0571 clause 8)
and never falls back to the controller's; a key written before reads false.
Tests: a row in the lease table of TestTheCopiedComposerComposesAsTheControllers; the old key (shaped as
EncodeGrantsUserList writes it today) and the flag's round trip added to the existing user-list case in
delivery_test.go; no new test function.

The grants part writes its list as an object of its own bucket, sealed to the bus node's key, and names it in
user-list.sealed; the node-engine of the node holding mesh-broker is granted that one key and an object by name, the
grants part its bucket (the controller's copy carries the same grants, byte for byte, golden regenerated there).
A state may name its readers (announce, NamedReaders): mesh-vault.bus-accounts is read by mesh-grants alone.
