- 学生提交时浏览器给每个窗体截图（运行时同一套 FormWindow 在屏幕外渲染），随提交保存 - 自动评分后进入 AI 评阅队列：按书上评价表给老师评分项打建议分、写评语（JSON 输出，服务器再校验、限制分数）； 发出的内容不含姓名学号；学生代码里像指令的文字一律当作品内容；学生又交了新的只评最新的 - 提示词按教材命名习惯校准（"缩写_含义"、书上规定的控件名、界面上不用的标签保留默认名不扣分）： 教材参考答案 28/30，默认控件名且没有注释 15/30 - 评阅页：界面截图标签页、AI 建议卡片（采纳、重新评阅）、全部采纳（不覆盖老师已评的分）、评阅后又提交的提醒； 成绩表显示"AI 建议，待确认"；学生在老师确认前看不到 AI 的建议 - 规范提示移到 shared，服务端组装提示词时也用 - 配置 DEEPSEEK_API_KEY、AI_MODEL；部署说明提醒 NPM 调大请求体上限 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

// 评分队列：学生提交后立即返回，后台按提交顺序评分（同时最多评 MAX_ACTIVE 份），结果写回数据库。

// 服务器重启前没评完的提交，启动时继续评。评完调用 onGraded（接着做 AI 评阅）。
