The bus module's tool hands the ask to the keeper through its own state
requests (design 25 § 12.2), as the caller the tool runner proved; the keeper
asks indexer_bus_state at once beside its backoff, applies what it answers,
records the hand act and writes back what it answered and at which revision.

The bus module's tools hold no grant of the seat's acting verbs (design 25
§ 12.3): nats_create, nats_apply, nats_recreate and nats_drop write a request
into the keeper's own state requests, stamped with stdio.CallerOf (a name in
the arguments is never the caller), and read its end back. recreate and drop
raise the operator's ask first, its option binding exactly that act; the
keeper acts only on the router's warrant for it (Warrant.For, Option.Performs),
after a snapshot of the entry's streams (bussnap, moved from the snapshot
command with a streams filter), says recreated or dropped, and records every
act as a hand act through mesh-hand-acts. A drop removes an orphan alone.

Served by the bus module's bundle from the keeper's own state asked and the
bus's monitoring endpoint (design 25 § 12.3): each entry's template, bus
names, settings asked and held and fill against its cap; check names each
object missing or differing; orphans what no accepted manifest asks for.
nats_history reads one entry's events, in order, from the bus module's own
stream BROKER_EVENTS on the tools' credential. The manifest test now holds
every tool and reading verb the manifest names to what the bundle serves.

The keeper's one periodic read (ADR 0595 §6): every entry that refuses when
full, by its fullest object; full raised at the raise mark (75 by default),
cleared only below the clear mark (70), so an entry at the mark does not flap;
an entry dropping its oldest is never read. HealthOf is the keeper's health
for its tool: unhealthy when its pass is more than three minutes old, its
first view has not answered (naming the indexer's verb), or verdicts wait on
its consumer unanswered past the bound; it names the entries refused, waiting
and full beside.

An entry made for a module whose newest accepted manifest no longer asks for
it is said orphaned and raised, never removed; asked again it is kept, its
binding said again with created and the condition cleared. A module missing
from a first view keeps its key (a set-aside manifest is not in it); an entry
never made leaves nothing, so the empty verdict ends that module's key.

Rows of the keeper's table test: a larger cap is applied with no event; a
smaller one is drifted with what differs, raised once, and drift-cleared once
the manifest asks what the bus holds again; an entry the bus already holds is
taken as made and its binding said, nothing made twice.

Each bus-state entry is planned into its objects (design 25 § 12.1): state a
bucket <module>_<local>; events, work queue, log and a bare stream a stream
<module>_<local> on mesh.bus.<module>.<local>.>; objects an object store;
a ledger its history stream, its state and index buckets and its snapshot
stream, one message per subject. The keeper makes what the bus lacks on its
own account; a refusal of its grant waits for the next check, a refusal of the
entry is said (refused) and raised, cleared by a later create. The comparison
of what is held and the orphans are in the same pass (CAT-N4, N5).
