How a chapter is delivered

One chapter is one idea taken to the point of use

Each chapter covers one idea to the point where you can use it, and comes two ways: a narrated explainer, and a deep dive audio discussion of around thirty minutes that works the same material at depth.

Self-paced throughout, and the same chapters can be taught as a cohort. Chapters run in order: each one assumes only what the chapters before it taught, and capability belonging to a later course is named and deferred rather than half-covered.
