Audit of package __init__ import cost turned up two eager ones: orchestrator/__init__.py (27 -> 2): was pure `from .X import Y` re-exports (registry_store, broker, docker_broker, gateway, service, server). Because importing any submodule runs the parent __init__, the CLI migration gate (orchestrator.store.store_manager, hit on every command) transitively dragged backend.docker, docker_broker, server, and http.server. Converted to the same lazy __getattr__ + _LAZY facade used by manifest/backend/egress/git_gate; the re-export API is unchanged and the docker/http drag is gone. cli/commands/__init__.py (78 -> 23): the registry imported all twelve handlers to build COMMANDS, so importing one command pulled all of them plus their deps. COMMANDS now maps each name to a thin lazy wrapper that imports its handler's module on first dispatch. Values stay callable, so the dispatcher and the patch.dict dispatch tests are unchanged; a CLI run now loads only the one command it dispatches. The remaining 23 is the dispatcher's own baseline (store_manager migration gate + help + log). Full unit suite green (2243); `bb help` + dispatch/migration-gate tests verified.

"""Per-host orchestrator service (PRD 0070).
|
|
|
|
A single persistent per-host service that will run the gateway functions
|
|
(egress / git-gate / supervise), coordinate with the console, and broker
|
|
agent launches. This package is being built bottom-up, starting with the
|
|
backend-neutral "consolidation core" that needs no VM packaging:
|
|
|
|
* `store.registry_store` — the SQLite runtime-state store + fail-closed
|
|
attribution (source IP + per-bottle identity token).
|
|
* `broker` — the signed, structured launch-request contract + a
|
|
`LaunchBroker` (stub for the harness) that verifies
|
|
provenance before acting.
|
|
* `gateway` — the consolidated per-host gateway: the `Gateway`
|
|
lifecycle contract (idempotent singleton). One
|
|
gateway shared by all bottles instead of one per
|
|
bottle; backend impls live under `backend/*/gateway`.
|
|
* `service` — the `Orchestrator`: owns the registry, brokers the
|
|
launch lifecycle (launch/teardown), manages the
|
|
shared gateway, attributes.
|
|
* `server` — the HTTP control-plane RPC (launch / teardown /
|
|
list / attribute / gateway / health).
|
|
|
|
The actual backend-native launch (a real docker/firecracker broker) and
|
|
the egress/git/supervise data plane land in later slices once this core is
|
|
proven (see the PRD sequencing: plain-process dev-harness -> docker
|
|
orchestrator -> firecracker).
