- bunfig.toml 的 [fmt]：不写分号、单引号、一行最长 160，和原来的写法一致 - .prettierignore：docs/教材摘要/ 是书上的摘录，不格式化 - 模板里一行写两条语句的事件处理（@keydown.delete、@dblclick）改成调用方法：去掉分号后拆成两行，Vue 编译不过 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（同时评的份数不超过检查项的并发上限，保证评分槽位能用满），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）。
