# 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.
