Reading paths

The book has four parts. Each has a natural audience, but none are gated — read what’s useful to you.

Part	For	What you’ll get
Part I: The Foundation	Everyone	The thesis. The shift from human-only to AI-native delivery, why it’s happening now, and the vocabulary the rest of the book uses. Start here regardless of role.
Part II: For Leaders	CEO, CTO, CIO, VP Engineering, Director, Head of Platform	Landscape, business case, reference architecture, governance, team structures, transition planning. The frame for deciding what to build, buy, or compose — and how to organize the team that will do it.
Part III: For Practitioners	Staff/Principal engineer, tech lead, senior developer building with agents this week	The runtime machine, the instrumented codebase, PROSE, the load lifecycle, attention economy, multi-agent orchestration, primitives as code. The substrate practitioners design and operate against.
Part IV: Case Studies	Everyone	Four worked examples — APM, this book, the publishing pipeline, the growth engine — showing the methodology in production. Read after Part II or Part III for grounding, or sample any one as a standalone.

The two appendices (Cross-harness reference, Genesis worked example) are reference material — bookmark them, return as needed.
