错题本
Mistake notebook
诊断和练习里答错的题会自动记到这里。按知识点举一反三，连续两次答对就算掌握；挑几道组成一张巩固卷打印出来。
Questions you miss in diagnosis and practice land here. Drill similar questions per topic — two in a row counts as mastered — and print a review sheet.
错题只保存在这台设备的浏览器里，换设备不会同步，清理浏览器数据会丢失——记得定期「导出」。
Saved in this browser only — no sync across devices. Export regularly.
组卷：先勾选错题；一道都不勾就用全部未掌握的题。每道原题后面会配一道同知识点的变式题。
Tick questions to include; with none ticked, all open questions are used. Each gets a same-topic variant.
关于错题本
About
功能设计参考开源项目 wrong-notebook（MIT，margrop / wttwins），代码为 VuuGrow 自己实现。变式题取自知识图谱题库中同一知识点的题（CC BY-NC 4.0，AI 生成初稿、未经教师审核），不调用模型。
Design follows the open-source wrong-notebook (MIT); the code is VuuGrow's own. Variants come from the knowledge-graph bank (CC BY-NC 4.0, AI-drafted, not teacher-reviewed).
