Summary
Design the first data model for storing incorrect answers and review metadata.
Problem
The error notebook is a core differentiator, but we do not yet have a stable model.
Proposed solution
Define entities, fields, and relationships for mistakes, retry history, and source links.
Why this matters
A weak data model here will slow down quizzes, reviews, and analytics later.
