Milestone B1 of issue 1966 (ADR 0595 §10 steps 1, 2 and 4; design 25 § 12). One delivery group with mesh-delivery, mesh-tools and mesh-catalog on branch feat/bus-state.

Contracts only (ADR 0578 §7, ADR 0593 §1): a requires item naming storage decodes into Manifest.BusState (kept off Requires, which names provisions); the storage types, templates, options and ledger effects as names; Membership.Bindings with a ledger's types; the new package buscalls (objects, streams, work queues, ledgers; MetaCall; IndexKey encoding each part); delivery.ManifestAccepted; the bus account kind ledger (ledger.<node>.<module>, own secret ledgers) and LedgerHistorySubject / LedgerSnapshotSubject. Additive: nothing a running module reads changes.

Acceptance: issue 1966 notes 8 and 10 (AC1-AC6, AC23, AC27, AC28).
Test budget: unit tests 607 -> 605 (over the 500 budget before; fell, no new test function).

A requires entry naming a storage type asks for bus state, read leniently beside the plain names (issue 1966 S1) 779ad9ac10

ADR 0595 §1: the typed long form {name, storage, template, options,
configuration} decodes into Manifest.BusState, its name also on Requires;
a key it does not know is set aside and named, never refused (ADR 0578 §3).
The requirements tests are one table.

Name the storage types, templates, options and ledger effects, and give a ledger its types (issue 1966 S2) 0bec849c40

The words of design 25 § 12.1 and ADR 0597 §1-2 as constants, and a
ledger's types (schema, operations each with its effect, indexes) on the
bus-state entry, so the judge, the bus module and the tool runner read one
contract. No bound and no rule: those are the judge's (ADR 0578 §7).

A membership carries its module's bus-state bindings, by local name (issue 1966 S3) e9c319c5a0

ADR 0595 §1, §7: the binding travels on the bus module's created and the
grants part writes it into the membership; omitted when empty, so a
membership without bindings encodes byte for byte as before. The two
address tests are one table.

A calls package of its own for objects, streams, work queues and ledgers (issue 1966 S4) 510d983cc6

ADR 0595 §9, ADR 0597 §10, design 25 § 12.5: the request and answer types
and method names of the bundle-pipe calls the tool runner serves, apply
naming the tool call it serves (ADR 0597 §7) and answering taken, its
sequence and state behind. It imports nothing of mesh-sdk, so a change
rebuilds only its importers; the package list names it.

The indexer's manifest-accepted event carries the manifest's bus-state entries whole (issue 1966 S5) 2122ba52c0

ADR 0595 §4, design 25 § 12.2: the bus module hears the accepted verdict
as an event with the entries, never reading the indexer's state; AcceptedOf
builds the body and EventID names it once per digest and judge.

A bus account kind ledger, named ledger.<node>.<module> and held in the tool runner's ledgers (issue 1966 S6) 6ec6cad968

ADR 0597 §9 and the lead's Q1 path: one ledger credential per module
assignment, minted by the vault like every kind; the grants part's copy
of buscompose gains the same kind alike (D5b).

A bus-state entry stays off Requires, which names provisions (issue 1966 S1) d3e10f68c5

A local name such as records is no provision: on Requires it would send
the placement looking for a provider nothing offers (the lead's ruling on
issue 1966 B1). BusState alone holds the typed entries.

Name the _meta key the tool runner hands a bundle the id of the tool call in flight under (issue 1966 S4) 25c08d09ec

MetaCall, mesh/call: the id ApplyRequest.Call names, so the runner stamps
the caller it proved as the operation's author (ADR 0597 §7; the lead's
ruling on issue 1966 B1).

Name a ledger's history and snapshot subjects in one place (issue 1966 S3) cc64794d4c

The grants part grants on them, the tool runner appends and snapshots on
them and the bus module creates the history over them, so the three read
one contract (the lead's ruling on issue 1966 B1; ADR 0597 §8, §9).

A ledger's binding carries its types (issue 1966 S3) 092260870b

The grants part copies them from the manifest-accepted entry, so the tool
runner checks an operation against its type without reading another
part's state (ADR 0596; the lead's ruling on issue 1966 B1).

An index's key and entry are one contract of the calls package (issue 1966 S4) 15fc2c4ce4

IndexKey and IndexEntry {instance, sequence}: the owner's watcher and the
tool runner's reindex write the same, so a reindex leaves the index as the
watcher keeps it (the lead's ruling on issue 1966 B1; ADR 0597 §4).

Encode each part of an index key, so no two keys meet and every part is a bus token (issue 1966 S4)

A raw value holding "." collided with a longer path, and a space is refused
by the bus: every byte outside [A-Za-z0-9_-] of a field value or an instance
path part is written =XX (review round 1 of issue 1966 B1).
