Refactor Candidates

After TDD cycle, look for:

• Duplication → Extract function/class
• Long methods → Break into private helpers (keep tests on public interface)
• Shallow modules → Combine or deepen — see DEEPENING.md in /codebase-design for dependency categories and seam discipline
• Feature envy → Move logic to where data lives
• Primitive obsession → Introduce value objects
• Existing code the new code reveals as problematic
