Chunk 2 of the host-control-server stack: close the PRD's **durable secret** gap and replace chunk 1's BOT_BOTTLE_BROKER_SECRET stopgap. - trust_domain.py: two new domains. LAUNCH_BROKER holds the durable HS256 key both the orchestrator (signer) and the host control server (verifier) share for the broker's launch JWT — a host-canonical key file minted 0600 on first use, so a restarted orchestrator re-verifies against the same key. HOST_CONTROLLER is the separate domain for the controller's own lifecycle endpoints, keyed by a key the orchestrator never holds (its role is `host`, deliberately outside control-plane ROLES). LaunchBrokerProvisioning is the fail-closed seam. - orchestrator_auth.py: ROLE_HOST, outside ROLES. - paths.py: key-file + env-var constants for both domains. Key resolution is split by owner (addresses codex review on #497): broker_secret(allow_host_file=...) — the host controller / dev-harness (True) may mint/read the durable host key file it owns; the GUEST orchestrator (--broker http, default False) must be *injected* the key and fails closed if it isn't. A guest that fell back to the host file would mint a process-local key unrelated to the host controller's, so startup would succeed but every launch would 401 — this prevents that silent divergence. Tested: domain boundary + separation, provisioning fail-closed, and broker_secret env-only (guest) vs host-file (host) resolution. pyright clean; pylint 9.86.
