The lighter sibling of provisioning — 1:many and broadcast, no credential,
just the broker's topic routing. A thin, audit-ready surface over the
broker's publish/subscribe:
- emit(type, body): publishes an Event carrying who emitted it (MESH_MODULE),
on which node (MESH_NODE) and when (ISO timestamp) — so a listener can
build a real audit trail.
- on(pattern, handler): react to events by topic pattern. The audit logger
is just on("#", ...).
Tested: a module emits; a targeted listener (module.umami.#) hears only its
events, the audit sink (#) hears every module's, and the metadata audit
needs is present.
The declared side — a manifest's emits/consumes, so the mesh knows the
event graph — and the audit-logger module are the next pieces.

Per novox/hq ADR 0044/0045: the sdk holds only what rarely changes and
is shared across modules; per-module code (a client, tool impls, a
create-a-resource adapter) lives in the module.
Five areas, real and tested:
- contracts: the runtime shapes module code touches (grant, credential,
a mesh Interface, tool + envelope types) — not the manifest schema,
which the control plane owns.
- provisioner: the reconcile harness every provider shares (watch grants,
create via the module's adapter, seal + write the credential, remove on
withdrawal). A module writes only the adapter.
- tools: registerModuleTools + collectTools — the serving harness; tools
and their client live in the module.
- messaging: the Broker/Envelope/event contract over the mesh broker; the
concrete binding is provided by the hosting runtime.
- primitives: AES-256-GCM seal/unseal, semver, resolved-env access.
Compiles (tsc, NodeNext) and passes tests: sealing round-trip + wrong-key
rejection, semver, tool registration (a thrower is skipped not fatal), and
the provisioner creating then removing a sealed grant.
