Replaces the alpine:latest placeholder with a real claude-bottle agent image, converted into a .smolmachine artifact via an ephemeral local OCI registry. Why the registry hop: smolvm pack create only accepts OCI registry refs. Empirically it rejects docker-daemon://, oci-layout://, docker-archive: tarballs, and every other transport tested — the crane backend treats anything with a scheme prefix as a registry hostname. To convert a locally-built docker image into a .smolmachine we have to push it somewhere smolvm can pull from. Smallest path: bring up registry:2.8.3 bound to 127.0.0.1:<random>, docker tag + docker push into it, smolvm pack create --image localhost:<port>/claude-bottle:<id>, tear down the registry. The .smolmachine is cached under ~/.cache/claude-bottle/smolmachines/ keyed by the docker image ID (first 16 hex chars of the sha256), so a Dockerfile change picks up a new image ID and invalidates the cache. Unchanged rebuilds skip the whole build → registry → pack pipeline. This puts `docker build` in smolmachines prepare (the docker backend defers it to launch). Necessary because pack_create needs the image ID to derive the cache key, and prepare is the only hook ahead of launch that runs once per slug. Adds: - claude_bottle/backend/docker/util.py: image_id / tag / push helpers (thin docker CLI wrappers). - claude_bottle/backend/smolmachines/local_registry.py: ephemeral_registry() context manager; pins registry:2.8.3 by digest, binds 127.0.0.1::5000 (loopback-only), force-removes on exit.

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.

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_pipelock_yaml # one file
Discovery is invoked with -t . (top-level dir = repo root) so the
claude_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_sidecar_bundle_image.py— builds Dockerfile.sidecars and probes that pipelock / gitleaks / mitmdump / supervise are all reachable inside the bundle.test_sidecar_bundle_compose.py— end-to-end compose-up of an agent + bundle pair; verifies the agent reaches the bundle via the legacy network aliases.
Canaries
tests/canaries/ holds upstream-regression checks (e.g. the pinned
pipelock digest's binary still runs). These are gated on
CLAUDE_BOTTLE_RUN_CANARIES=1 and not part of the per-push suite.
They're invoked by the scheduled canaries workflow.
CLAUDE_BOTTLE_RUN_CANARIES=1 python -m unittest discover -t . -s tests/canaries -v
What's NOT covered
claude_bottle/ssh.pyend-to-end (would need a fake SSH host inside the container).- A live SSH-through-pipelock 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 claude_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.
