| 1 | """Comprehensive tests for ``muse merge-base`` and ``snapshot-diff``. |

| 3 | Coverage tiers |
| 4 | -------------- |
| 5 | - Integration: linear ancestor, diverged branches, no common ancestor, |
| 6 | branch name resolution, HEAD resolution, JSON/text format |
| 7 | - Security: ANSI in paths stripped in text mode, errors to stderr |
| 8 | - Stress: 10-commit chain merge-base, 50-path manifest diff |
