feat: #34 - Enforce vertical TDD workflow with 4-phase process#35
Conversation
Replace simple presence-check TDD enforcement with a structured 4-phase workflow (Planning → Tracer Bullet → Incremental Loop → Refactor) that prevents horizontal slicing — where agents write all tests first then all code, producing brittle implementation-coupled tests. Adds per-cycle checklist, reference documents for mocking policy, interface design, test quality, and refactoring guidance. Updates implementer agent to inject TDD reference excerpts into subagent prompts.
