| 1 | """Comprehensive tests for ``muse status``. |
| 2 | |
| 3 | Covers: |
| 4 | - Unit: status correctly identifies clean, added, modified, deleted files |
| 5 | - Integration: status after commit vs after changes |
| 6 | - E2E: CLI flags (--short / -s, --branch / -b, --format json / text) |
| 7 | - Stress: many tracked files, large workspace |
