The controller ended by its unassignment (ADR 0590): its user, its lease's cut and reads, the
operator's hand path to its compositions and its writers' rows go; an enrolling node enrols
through mesh-enrolment alone; the desk's prompt stays the vault's alone (DeskOnly). The golden
lists are now this composer's own, taken first from the controller's with its user removed.
The bus module's tools may remove the controller's leftovers by name, consumers, CONTROL,
ASSIGNMENTS, its 17 buckets and each node's declaration files' bucket, under the word
controller-leftovers (clause 6). The provisioner client reads placement in place of the
assignments mirror. Issue 1126 B3a, B5.

ADR 0587 §1-§3 (changing ADR 0561 §5) make mesh-enrolment the only caller of the vault's enrolment-token and
node-account and a caller of sign, and §2 its bucket enrolments read by it and by the grants part as a named reader.
The holder calls the vault through its manifest's invokes, in its own name, as any caller does; while the vault serves
either enrolment verb every other principal is denied both, however wide its grant (a runtime's or an agent's `*`),
as ControllerOnly denies the desk's prompt. The writers table gains the open enrolments (mesh-enrolment) and the
node-logins (the vault), each one writer; NamedReaders names the grants part for enrolments. Golden lists unchanged.
Tested as a subtest of TestTheCopiedComposerComposesAsTheControllers, no new test function.

ADR 0582 clause 3 composes the bus's user list without the controller's write on the lease key and update of
the lease's bucket. Records.LeaseCut, set by the grants part from the write's second step, drops the
controller's $KV grant on the lease, denies it the bucket's update, purge, delete and message delete (its
$JS.API.> reaches them), and lets the grants part write the key holder alone. The bus module's tools account
may read and update the lease's bucket, for the expiry tool the write and the hand-back call. Without the cut
the lists equal the controller's golden.
Tests: rows added to TestTheCopiedComposerComposesAsTheControllers' tables (the cut on and off; the tools
account's lease grants); no new test function.

The engine composes its node's wants itself, so the derivation the controller keeps
privately moves beside the layout: DeclaredPackagesOf gives the mirror's bytes from the
compositions, DiffDeclaredPackages what the node seat's verb packages compares until the
lease write, and EnginePackagesRead names the state as readers declare it (mesh-host.packages,
as mesh-host.data). Each engine may read the controller mirror's key of its own node alone.

mesh/check pass c28c645ca406 on 5ae69df8ccde | unit 4510 run, 4259 kept, 49 skipped | integration 4589 run, 4361 kept, 51 skipped | over bound: unit, …
The contract (state name, key form, value) is in delivery; buscompose grants the engine its own
node's keys of mesh-host_data and each node's disk-load a read of its own node's keys alone, the
same way the engine's other states are granted.

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.
The copied bus composer grants mesh-grants' principal $JS.API.STREAM.CREATE.<stream> and
$JS.API.STREAM.INFO.<stream> for each bucket (KV_<module>_<state>), log (LOG_<module>_<log>) and
module stream a placed module's manifest declares, each by its own name: NATS wildcards are whole
tokens, so nothing narrower than an exact name exists and nothing wider is granted. The writers
table lets the grants part create, never update or delete. The operator allowed this one grant
on 2026-10-26 08:54, beside the memberships grant of 22:31 (ADR 0547 clause 1 and 5).
The expected lists were written again by the controller's own internal/broker with the same
change (mesh-control fix/1790-grants-create-buckets); a fixture now places mesh-grants beside the
builder's state, log and stream.
Issue: 1790
The grants part composes the bus's user list with the composer the controller uses (ADR 0547 §5), copied rather than
moved: the controller is not changed and keeps its own until it loses the lease. Left out: the bus client, the broker's
address from the environment and the client's two methods; the lease's two subjects are copied in.
One table test holds the copy to four meshes' lists and the server golden, written by the controller's own
internal/broker from the same fixtures (testdata/controller-user-lists.json).
