fix(smolmachines): give pty_resize side-channel DEVNULL stdin so it survives under tmux
Inside tmux the dashboard's smolmachines launch crashed within
~100ms of the wrapper Popen-ing the main smolvm exec child —
sometimes with rc=137 (SIGKILL), sometimes with smolvm
spitting a runc-style "load `config.json`: cannot parse the
data: parse error: trailing garbage" and exiting 1. The same
wrapper ran fine outside tmux. Diagnostic logs showed the
SIGKILL landed ~100ms after the wrapper kicked off its
initial `sync()` (which fires the side-channel smolvm exec).

Root cause: the side-channel `subprocess.run([smolvm, machine,
exec, --, sh, -c, ...])` did not specify `stdin=`, so it
inherited the wrapper's stdin — the tmux pane PTY. The main
smolvm child (the agent session) also had that PTY as stdin.
Two concurrent smolvm processes sharing the PTY's
foreground-process-group / input plumbing caused smolvm to
abort one of them. iTerm's PTY plumbing apparently tolerated
this; tmux's didn't.

Fix is one line in `_push_size`: `stdin=subprocess.DEVNULL`.
The side-channel never needs stdin — it runs a fire-and-forget
`stty` and exits. Verified end-to-end: pre-fix the wrapper
crashed under `tmux respawn-pane` against a live VM; post-fix
the same invocation completes cleanly.

Also drop the diagnostic log added in 37bd11b — we have the
fix.

Regression test:
`test_side_channel_uses_devnull_stdin` locks the
`stdin=DEVNULL` invariant so a future "let's simplify the
subprocess.run kwargs" refactor surfaces this immediately.

637 unit tests pass.

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)
  unit/
    test_pipelock_classify.py
    test_pipelock_allowlist.py
    test_pipelock_yaml.py
    test_manifest_runtime.py
  integration/
    test_pipelock_sidecar_smoke.py
    test_dry_run_plan.py
    test_orphan_cleanup.py
  canaries/
    test_pipelock_image.py          # opt-in; see below

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.pycli.py start --dry-run --format=json emits a structured plan that contains the resolved egress allowlist and the bottle's runtime, and creates zero Docker resources.
  • test_orphan_cleanup.pynetwork_remove is 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.py end-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

  1. Pick the directory: tests/unit/ for a pure unit test, tests/integration/ for one that needs Docker.
  2. Filename: test_<topic>.py.
  3. Boilerplate:
    import unittest
    
    from claude_bottle.<module> import <symbol>
    
    class TestThing(unittest.TestCase):
        def test_x(self):
            ...
    
    if __name__ == "__main__":
        unittest.main()
    
  4. For Docker-dependent tests, decorate the class with @skip_unless_docker() from tests._docker.
