| operation_history.py | 81% | 31/159 | ✅ Good |
| search.py | 86% | 8/58 | ✅ Good |

**Assessment**: CLI and supporting modules have good coverage.

#### ⚠️ Lower Coverage (<80%)

| Module | Coverage | Missing Lines | Priority | Notes |
|--------|----------|---------------|----------|-------|
| logger.py | 77% | 18/79 | Low | Runtime utility, indirectly tested |
| backup_manager.py | 66% | 19/56 | Medium | Backup/restore edge cases |
| file_utils.py | 67% | 7/21 | Low | Small utility module |
| yaml_utils.py | 59% | 25/61 | Medium | YAML I/O edge cases |

**Assessment**: Lower coverage modules are primarily utilities with acceptable test coverage for v0.10.0.

### 1.3 Missing Coverage Analysis

#### logger.py (77%, 18 missing lines)
- **Missing**: Edge cases in log rotation, cleanup
- **Impact**: Low (logs are not critical to functionality)
- **Recommendation**: Acceptable for v0.10.0, improve in v0.10.1

#### backup_manager.py (66%, 19 missing lines)
- **Missing**: Complex backup scenarios, error recovery
- **Impact**: Medium (backups are safety feature)
- **Recommendation**: Add 5-7 tests for edge cases in v0.10.1

#### yaml_utils.py (59%, 25 missing lines)
- **Missing**: YAML parsing edge cases, encoding issues
- **Impact**: Medium (YAML is core storage)
- **Recommendation**: Add 8-10 tests for edge cases in v0.10.1

**Conclusion**: Acceptable gaps for v0.10.0 release. No critical functionality uncovered.
