End-to-end launch flow for the smolmachines backend. Brings up
the per-bottle docker bridge + sidecar bundle, creates and
starts the smolvm guest pointed at the bundle's pinned IP via
TSI's `--allow-cidr <bundle-ip>/32`, yields a SmolmachinesBottle
handle that routes exec/cp through `smolvm machine exec / cp`,
tears everything down on context exit.
launch.py:
- ExitStack-managed: create_bundle_network → start_bundle →
machine_create → machine_start (each registered for reverse
teardown).
- daemons_csv="" for chunk 2d — bundle init logs "no daemons
selected" and idles. Real daemon bringup with inner-Plan-driven
env + volumes lands in chunk 4.
bottle.py:
- SmolmachinesBottle.exec → smolvm.machine_exec (captured).
- SmolmachinesBottle.exec_claude → direct subprocess.run with
inherited TTY for interactive sessions.
- SmolmachinesBottle.cp_in → smolvm.machine_cp.
Architecture pivots forced by smolvm 0.8.0's CLI shape:
1. `--from <smolmachine>` and `--smolfile <toml>` are MUTUALLY
EXCLUSIVE in smolvm 0.8.0. We need --from to avoid the
registry-pull race that bit us on machine_start (libkrun
agent's network attempt got refused by macOS with
"connect: permission denied" on IPv6). So Smolfile is dropped
entirely; per-bottle env + allow_cidrs flow as CLI flags
(`--allow-cidr CIDR`, `-e K=V`) directly to machine_create.
2. `smolvm pack create --image` doesn't pull from the local
docker daemon — only OCI registries via crane. The real
claude-bottle:latest image lives in the local docker daemon
and isn't reachable that way. Chunk 2d ships with an alpine
placeholder; the agent-image-conversion gap belongs to
chunk 4 (push the image to a registry, or smolvm grows a
docker-daemon transport).
Other changes:
- machine_create grew `image=` / `from_path=` / `allow_cidrs=`
/ `env=` kwargs; smolfile= dropped.
- bottle_plan: smolfile_path → agent_from_path + guest_env.
- prepare: pack_create against `alpine:latest`, cached under
~/.cache/claude-bottle/smolmachines/ keyed by image ref.
- Deleted smolfile.py + test_smolfile.py (dead code now).
Tests:
- Unit: 540 passing (smolvm wrapper grew 4 new flag forms; one
test renamed to reflect --from + --allow-cidr + -e combo).
- Integration: 3 new cases in tests/integration/
test_smolmachines_launch.py, gated on Darwin + smolvm on PATH
+ docker + not GITEA_ACTIONS:
* smoke: bottle.exec("echo hello-from-vm") round-trips with
the correct stdout + returncode.
* localhost-reach probe: agent dials 127.0.0.1:9 → connect
refused (TSI's <bundle-ip>/32 allowlist doesn't include
loopback). The regression test for the gap the PRD design
pivot was about.
* egress-port-bypass probe: agent dials <bundle-ip>:9099
(egress's port) → connect refused. Chunk 2d has no
daemons running so nothing's listening anyway; chunk 3
will preserve this property once egress is up but bound
to 127.0.0.1 inside the bundle.
End-to-end smoke + both probes green locally on macOS with
smolvm 0.8.0.

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
tests/
fixtures.py # JSON manifest builders (shared)
_docker.py # docker-availability skip helper (shared)

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.
