06. Module 02 — Revision

Review loop

1. Skim the table of contents in 02_explainer.md.
2. Re-read only the fuzzy chapters in 02_explainer.md.
3. Re-do the self-check questions in 01_weekly_plan.md from memory.
4. Run the spaced questions in 04_daily_recall.md without notes.
5. Sketch the Chapter 6 failure-fix table from 02_explainer.md §6.1.
6. Revisit implementation mistakes from 05_hands_on_lab.md.

Reflection prompts

1. Which failure-fix transition now feels obvious to you, and which one still feels shaky?
2. If you had to explain self-attention to a junior engineer in two minutes, what picture would you use?
3. What production risk do you now notice earlier: token budget mismatch, order loss, or long-context cost?
