How to read the book

New readers can begin with Chapters 0–2. The theoretical route continues through Chapters 3–10 and 21. The causal route connects Chapters 5–6 with Chapter 11; Chapter 7 gives the general tangent semantics of decision making, while Chapters 12–14 treat architectures, adapters, and skills; and Chapters 15–20 treat trajectories, preferences, relations, distributed claims, arguments, and trustworthy foundation-model foundries. This is an advanced companion to Categories for AGI; readers seeking a slower introduction may begin with that book.
