| 1 | """Tests for Phase 3.3 — Knowtation CLI hooks (cli_hooks.py). |
| 2 | |
| 3 | Covers the six runners that dispatch ``muse code`` commands to the |
| 4 | note-metrics helpers when the active domain is ``knowtation``. |
| 5 | |
| 6 | Test tiers (Rule #0): |
| 7 | 1. Unit — each runner handles missing-arg defaults via getattr fallbacks |
| 8 | 2. Integration — JSON-mode output is shape-correct and stable |
| 9 | 3. Security — runners survive corrupt manifests and missing snapshots |
| 10 | |
| 11 | Notes |
| 12 | ----- |
| 13 | These tests intentionally exercise the runners *without* a real Muse repo |
| 14 | context — they monkeypatch the snapshot/commit lookups to use synthetic data, |
| 15 | which keeps them fast and isolated from store layer changes. |
