| 1 | """Comprehensive tests for ``muse stash``. |
| 2 | |
| 3 | Covers: |
| 4 | - Unit: _load_stash / _save_stash atomic write, size guard |
| 5 | - Integration: stash → pop, list, drop |
| 6 | - E2E: full CLI via CliRunner |
| 7 | - Security: stash.json size limit, atomic writes, sanitized output |
| 8 | - Stress: many stash entries, repeated save/load |
