A structured system for working through books like you'd work through a textbook with a tutor. It builds a local wiki as you go, compiling chapters into concepts, models, and cases, then tests your understanding with Socratic questioning before letting you move forward. The mastery test is strict: you need to explain, give examples, and apply ideas, not just say you got it. Includes spaced repetition review and cross-book comparison. Useful if you're reading to actually learn something rather than just finish the book. The pedagogy is deliberate, maybe overkill for casual reading, but that's the point.
