Reading model

How the challenge notes are structured

1. Context

Start with the objective, difficulty, source workspace, and the safest sanitized summary.

2. Method

Follow the evidence trail and the technique decisions that mattered, without exposing raw secret material.

3. Lesson

End with reusable operator learning: what to notice next time and how to validate the same class of issue.
