claude_bottle/yaml_subset.py — stdlib-only, ~450 lines. Parses the
bounded shape claude-bottle's manifest files use:
- Block mappings (top-level + nested via indentation)
- Block lists (under a key, items can be scalars or block-style
mappings whose keys align with the rest after the dash)
- Inline lists `[a, b]` and inline dicts `{a: 1}` for one-level
leaves
- Quoted (single + double) and bare strings
- Scalars: string, int, true/false, null/~
Rejects, each with a clear pointer at the line number:
- `yes`/`no`/`on`/`off`/`Y`/`N`/`TRUE`/`FALSE` — only literal
`true` / `false` are bools (the Norway problem stays solved by
"quote your strings if they look like bools")
- Bare strings that look like dates / octals / hex / floats
- Anchors (`&`/`*`), aliases, YAML tags (`!!str`)
- Multi-line block scalars (`|`, `>`)
- Tabs in indentation
- Nested flow style (only one level allowed)
Public API:
parse_yaml_subset(text) -> dict[str, object]
Top level must be a mapping.
parse_frontmatter(text) -> (dict, body_text)
Strips `---` delimiters, parses content as YAML subset, returns
the verbatim body text after the closing fence.
46 unit tests covering every construct the real manifest files use
(the cred_proxy.routes structure, role-as-inline-list, nested
ExtraHosts dicts) plus every rejection case listed in PRD 0011.
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_pipelock_sidecar_smoke.py— drivesDockerPipelockProxy.prepare.start(the production code path) against a real Docker daemon and probes the sidecar's/healthfrom an in-network curl container.
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_removeandPipelockProxy.stopare idempotent against missing resources, so the EXIT trap can call them unconditionally.
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.
