sha256:88ac91129873e6a496e9189515aa690eb893ae25d69c8f72af141a2be5068eb3 docs: docstring sprint contract→find-symbol — idiomatic run… Sonnet 4.6 patch 141 days ago
1 """Seven-tier tests for ``muse/cli/guard.py`` — ``require_clean_workdir``.
2
3 Tiers
4 -----
5 Unit — force bypass, clean workdir, added-only is safe, dirty exits.
6 Integration — text vs JSON format, target_manifest filtering, truncation at 10.
7 End-to-end — guard fires through real CLI commands (reset --hard, checkout).
8 Stress — 500 dirty files, repeated calls on same repo.
9 Data integrity — target_manifest OID comparison logic, deleted-in-target blocks.
10 Security — ANSI injection in operation name, null byte in path, path traversal.
11 Performance — completes under 2 s on a clean repo.
