Chunk 1 of the host-control-server stack: close the PRD's **transport** gap. Today LaunchBroker.submit(token) is an in-process method call from OrchestratorCore; this makes it a real out-of-process service reached over HTTP. - host_server.py: the host control server. A pure dispatch() (POST /broker verifies a signed token via the existing verify_request + _launch/_teardown path, GET /health) wrapped by a thin http.server adapter, mirroring orchestrator/server.py. Only the signed token crosses the wire; provenance/schema failures are fail-closed 401s that never touch the backend, a backend launch failure is a 502. - broker_client.py: BrokerClient — a drop-in submit(token) that POSTs the signed token to the host controller. A 401 re-raises as BrokerAuthError so the launch path's rollback is identical local or remote. - broker.py: SubmitBroker Protocol — the one method OrchestratorCore depends on, satisfied by both LaunchBroker and BrokerClient, so the core is unchanged (service.py annotation only). - __main__.py: wire `--broker http` behind the shared-secret env var (BOT_BOTTLE_BROKER_SECRET, hex) — a chunk-1 stopgap the durable TrustDomain key (chunk 2, #476) replaces. Tested: pure-dispatch cases, BrokerClient with HTTP mocked, and a real-socket sign -> POST -> verify -> act round-trip (incl. fail-closed forged token). pyright clean; pylint 9.86.

"""Run the orchestrator control plane as a plain process (PRD 0070 dev-harness).

python -m bot_bottle.orchestrator [--host H] [--port P] [--db PATH]

The PRD sequences the orchestrator as a plain-process dev-harness first, so
|
|
the consolidation core (registry + attribution + HTTP control plane + live
|
|
reload) can be exercised with fast iteration, decoupled from any VM /
|
|
container packaging. Wrapping this exact service in a backend-native unit
|
|
(docker container, then Firecracker VM) comes later.
