## Review Methodology

### Process Overview
1. **Code Reading**: Read all 2,897 LOC of implementation
2. **Static Analysis**: mypy strict, ruff check
3. **Test Execution**: Run 183 tests with coverage
4. **Performance Profiling**: Measure operation times
5. **Security Audit**: Check for vulnerabilities
6. **Documentation Review**: Verify completeness
7. **Integration Testing**: Verify component interaction

### Tools Used
- **mypy**: Type checking (strict mode)
- **ruff**: Linting (E501, etc.)
- **pytest**: Test execution with coverage
- **pytest-cov**: Coverage analysis (HTML + term)
- **grep/glob**: Code search and pattern detection
- **Manual Review**: Architecture, design patterns, security

### Coverage Achieved
| Module | Lines | Uncovered | Coverage |
|--------|-------|-----------|----------|
| memory.py | 222 | 38 | 83% |
| memory_store.py | 97 | 5 | 95% |
| knowledge_base_compat.py | 71 | 15 | 79% |
| task_manager_compat.py | 98 | 17 | 83% |
| migrate_to_memory.py | 107 | 10 | 91% |
| memory.py (CLI) | 247 | 45 | 82% |
| migrate.py (CLI) | 68 | 52 | 24%* |

*Low coverage on CLI migrate.py is acceptable (Rich formatting, interactive prompts)
