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.

"""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.
