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.

Retire "sidecar" for the consolidated per-host path (PRD 0070 naming
decision): the orchestrator is the umbrella/control plane, and the
egress/git/supervise data-plane unit it runs is the "gateway".
- git mv sidecar.py -> gateway.py and the two integration + one unit test
files; DockerSidecar->DockerGateway, Sidecar->Gateway,
SidecarError->GatewayError, SIDECAR_*->GATEWAY_*, ensure_sidecar->
ensure_gateway, sidecar_status->gateway_status, container name
bot-bottle-orch-sidecar->bot-bottle-orch-gateway.
- Prose rename across broker/registry/egress/policy_resolver + PRD 0070.
- Preserved: the image name bot-bottle-sidecars, the
BOT_BOTTLE_SIDECAR_IMAGE env var, Dockerfile.sidecars, and PRD 0069's
own stage-name cross-references (that doc still uses "sidecar").
No behavior change. Full unit suite green (1679 tests; the 13
test_sidecar_init /bin/sleep errors are pre-existing NixOS-local noise).

Second slice of PRD 0070, still a backend-neutral dev-harness:
* orchestrator/broker.py — the launch-broker contract. A LaunchRequest is
structured (static ids/flags only — bottle id, pool slot, a
content-addressed image_ref; never a path/argv) and signed as a compact
HS256 JWT so the broker verifies PROVENANCE before acting: a compromised
co-located component can't forge a launch without the shared secret.
verify_request is fail-closed (bad sig / malformed / off-schema -> raise).
Stdlib only (no runtime deps). Ships a StubBroker that records verified
requests for the harness/tests.
* orchestrator/service.py — the Orchestrator: owns the registry and brokers
the lifecycle. launch_bottle mints the bottle + sends a signed launch,
rolling the registry entry back if the launch fails (no orphans);
teardown_bottle brokers teardown then deregisters; attribute delegates.
* control_plane.py — POST /bottles now launches, DELETE tears down (both go
through the Orchestrator + broker). dispatch/server take an Orchestrator.
* __main__.py wires an ephemeral secret + StubBroker for the harness.
Tests: broker sign/verify round-trip, tamper/wrong-secret/malformed/off-schema
rejection, StubBroker fail-closed; Orchestrator launch->registry->attribute,
teardown, rollback-on-broker-failure; control-plane updated for launch/teardown.
Full suite green (only the pre-existing /bin/sleep errors); harness does
launch -> attribute -> teardown over HTTP.
