6. Govern the Blast Radius
If Part II handed you a fast, capable, occasionally-wrong new kind of worker, this chapter is about the question it forces: how much rope do you give it, and how do you keep a mistake from becoming a catastrophe? It is the same question you have always faced with talented, autonomous people. The answer that scales — to senior engineers and to coding agents alike — is the single most transferable idea in this book: govern the blast radius, not the steps.
