| 1 | """Supercharge tests for ``muse restore`` — performance, data integrity, |
| 2 | object-store corruption, concurrency, and source+staged combos. |
| 3 | |
| 4 | Coverage tiers added here: |
| 5 | - Performance: duration_ms present, non-negative, and reasonable |
| 6 | - Data integrity: complete JSON schema, correct types, exit_code field |
| 7 | - Error mapping: object store corruption → exit code 3 (INTERNAL_ERROR) |
| 8 | - Concurrent: two threads restore independent files without racing |
| 9 | - Source+staged: --source --staged restores stage entry from source commit |
| 10 | - Text summary: text output includes "Restored N" summary line |
| 11 | - Docstring gap: _resolve_source_manifest returns {} for bad ref (not raises) |
