Use ONLY when the user explicitly asks for 古法编程 mode. Slow-path Build mode that replaces normal AI code-drop: forces line-by-line principle questioning (default) or human transcription before code lands. Optional TDD rhythm (test-first → red → impl → green) auto-routed by content type, opt-out by user. Reads an existing plan file when present, hands off to /finalize when done. Do NOT auto-invoke.
