+## Findings
+- Single responsibility: single type definition; cohesive.
+- Dependency inversion: static utility types limit substitution; consider abstraction if behavior must vary.
+
+## Maintainability Notes
+- Minimal surface area; easy to reason about.
+
+## Recommendations
+- Consider interface-backed abstraction if alternate implementations are needed.
