Non-Fiction Patterns
Chapter template: Hook(empathy) → Problem(why it matters) → Evidence(proof) → Framework(solution model) → Application(concrete examples) → Summary(3 points + bridge).
Learner levels: Novice ("Why?" · analogies) → Competent ("How?" · real scenarios) → Expert (root causes · edge cases).
Evidence hierarchy (high→low): Research(peer-reviewed) → Data(statistics) → Case Study(3+) → Experience(post-mortems) → Anecdote(empathy only). Core claims require Data+.
Argument: Claim(what) + Warrant(why valid) + Impact(so what). Strong = Claim + multiple Warrants + specific Impact.
Callouts (≤3/chapter): Tip · Warning · Example · Exercise.
Difficulty gradient: ▁▂▃ Intro → ▃▄▅ Basics → ▅▆▇ Practice → ▇▇██ Advanced. First chapter of each part slightly easier than last of previous.
