Land the `decnet bus` worker and `get_bus()` factory. Transport is a host-local UNIX-domain socket (0660, group=decnet); authz is the file mode. Wire framing is a tiny verb-line + 4-byte-BE length + orjson body. NATS-style wildcard topics (`*`, `>`). At-most-once, fire-and-forget — DB stays the source of truth. `FakeBus` / `NullBus` for tests and the disabled path. Cross-host federation is deferred to a future `--bridge-tcp` mode; DEBT-030 is master-only and unblocked.
