Guide an assignment-first learning loop using an unaided V0 draft, focused study, a fresh V1 redraft, one-question-at-a-time grilling, and a user-authored V2 final answer. Use for homework, course assignments, case analyses, reading responses, teach-backs, or requests such as "숙제 시작하자", "공부 전후 답을 비교하자", "내 답을 검토해줘", and "이전 학습 세션을 이어가자".
