Read the first diagram as a timing map: this guide is for a named pressure, not for wandering the whole course-book. Read the second diagram as the guide loop: arrive with a concrete question, use only the matching sections, then leave with one smaller and more honest next move.

This page turns the course into a repeatable rehearsal loop. The goal is not only to finish reading. The goal is to improve judgment under change.

  1. Read the module overview first.
  2. Read the lesson sequence in order.
  3. Pause after each major concept and write one sentence beginning with: "This boundary exists because..."
  4. Inspect the capstone package or guide that expresses that boundary.
  5. Run or review the matching executable proof.
  6. Compare your understanding with _history/worktrees/module-XX when the module ends.
  7. Rephrase the lesson in terms of change: what becomes easier to refactor or review now?

Questions that travel across modules

  • What is still pure?
  • What is now explicit data?
  • Where does materialization happen, and why there?
  • Which failure shape is visible to the caller?
  • Which effectful behavior is controlled by a protocol, shell, or adapter?

What this prevents

This practice loop prevents passive reading, diagram memorization, and the common mistake of admiring a functional abstraction without being able to say how it makes the codebase safer to change.
