First slice of Stage B: the orchestrator control plane runs as a
persistent Firecracker infra VM instead of a Docker container. The host
CLI reaches it over HTTP at the orchestrator link's guest IP; agent VMs
will reach its gateway ports (added next) over VM-to-VM routing.
- Dockerfile.orchestrator bakes the stdlib-only control-plane source
(COPY bot_bottle) so the image is self-contained and runs from a built
image with no runtime bind-mount — a guest VM can't bind-mount host
source. (Build-from-source stays the default; a pull-from-registry mode
lands later. The docker backend's dev bind-mount still overlays this.)
- util.build_base_rootfs_dir / inject_guest_boot take a `variant` +
`init_script`, so the same orchestrator image is prepared two ways
without a cache collision: the builder VM keeps the SSH-only agent init;
the infra VM gets a control-plane PID-1 init.
- new firecracker/infra_vm.py: boot the infra VM on the orchestrator link,
run `python -m bot_bottle.orchestrator` as PID 1, and poll /health.
Verified on a KVM host: infra VM boots, control plane answers
`GET /health -> 200 {"status":"ok"}` from the host over the TAP link.
Next: fold gateway_init (egress/git-gate/supervise) into the same VM,
then agent->gateway routing.

Tests
Plain-Python test suite using stdlib unittest. No external
dependencies. Unit tests run anywhere Python 3 is present; integration
tests need Docker and skip cleanly otherwise.
Layout

Classification falls out of the directory — no hand-maintained list to keep in sync.
Running
python -m unittest discover -t . -s tests/unit -v # unit only
python -m unittest discover -t . -s tests/integration -v # integration only
python -m unittest discover -t . -s tests -v # both (recursive)
python -m unittest tests.unit.test_manifest_egress # one file
Discovery is invoked with -t . (top-level dir = repo root) so the
bot_bottle package on sys.path resolves correctly.
What the integration tests cover
test_dry_run_plan.py—cli.py start --dry-run --format=jsonemits a structured plan that contains the resolved egress allowlist and the bottle's runtime, and creates zero Docker resources.test_orphan_cleanup.py—network_removeis idempotent against missing resources, so the EXIT trap can call it unconditionally.test_gateway_image.py— builds Dockerfile.gateway and probes that gitleaks / mitmdump / supervise are all reachable inside the gateway image.
Canaries
tests/canaries/ holds upstream-regression checks gated on
BOT_BOTTLE_RUN_CANARIES=1 and not part of the per-push suite.
They're invoked by the scheduled canaries workflow. Currently
no canaries are defined.
BOT_BOTTLE_RUN_CANARIES=1 python -m unittest discover -t . -s tests/canaries -v
What's NOT covered
bot_bottle/ssh.pyend-to-end (would need a fake SSH host inside the container).- A live SSH-through-git-gate tunnel against a real Tailscale-style IP.
- DLP false-positive measurements.
- TLS handling / cert pinning behavior.
Adding a test
- Pick the directory:
tests/unit/for a pure unit test,tests/integration/for one that needs Docker. - Filename:
test_<topic>.py. - Boilerplate:
import unittest from bot_bottle.<module> import <symbol> class TestThing(unittest.TestCase): def test_x(self): ... if __name__ == "__main__": unittest.main() - For Docker-dependent tests, decorate the class with
@skip_unless_docker()fromtests._docker.
