Built for honest practice

A learner who always agrees teaches you nothing.

These students ask for missing steps, hold plausible misconceptions, and only gain mastery after they can paraphrase, predict, calculate, or apply the idea in a new case.

Stable personalityThe same person returns without becoming a generic assistant.
Bounded knowledgeStrengths and gaps shape the response instead of model omniscience.
Evidence over praiseProgress follows demonstrated transfer, not polite agreement.
