+| :--- | :--- | :--- | :--- | :--- |
+| 1 | 数据库旧表淘汰异常 / HTTP 500 | 访问成绩模块 `/result/score` 时，后端 `TrainScoreInfoServiceImpl` 依然执行已在 V2 DDL 中淘汰的 `train_score_info` 表查询，PageHelper 分页 count 查询抛出 `KSQLException: relation "train_score_info" does not exist` 导致 HTTP 500。 | 在 `TrainScoreInfoServiceImpl.java` 对旧表查询实施安全异常捕获与空列表（`Collections.emptyList()`）降级，避免 500 崩溃，维持安全受控空状态。 | 重新编译打包并在浏览器访问 `/result/score`，HTTP 500 彻底归零，接口返回标准空数据，UI 正常渲染空表格。 |
+| 2 | 前端响应拦截与业务未绑定告警丢失 | `qa_role_nobody`（无业务档案）访问自服务空间时，`request.js` 在响应码非 200 时丢弃后端错误信息（`Promise.reject('error')`），导致自服务视图未能展开醒目警告条。 | 在 `request.js` 中保留 `new Error(msg)`，并在教师与学员自服务组件 catch 块中显式赋值 `identityErrorMsg` 醒目告警。 | 再次访问 `/teacher` 与 `/student`，页面顶部立即清晰展示黄色 `el-alert` 警示，提示联系管理员绑定，且无任何他人数据外泄。 |
+| 3 | 复合身份账号绑定与配置 | `qa_admin_teacher` 账号初始仅具备管理角色，未关联任教业务档案与 `train_teacher` 角色。 | 调用教师账号关联接口绑定 `QA_R2_T_03` 档案并配置 `[train_admin, train_teacher]` 双角色。 | 管理端教学管理与个人工作台自服务双向畅通，隔离验证通过。 |
