Validate tests against Detroit School (Classical) TDD principles: real objects over mocks, state verification, sociable tests. Use when reviewing test quality, when tests look mock-heavy or brittle, or ensuring tests reflect real behavior. Do NOT use for writing tests (use bug-fix-tdd), full PR review (use pr-reviewer-3a).
