- 名单导入容错：rowsToStudents 加去重/跳过统计、表头正则扩充、.0 尾巴清理；importFile 返回精确 count
- 看板：修复 .repeat(0) 空状态坏代码；新增实时点 stale 指示（手动/自动刷新失败变红 + 提示刷新中断）；
手动刷新按钮加刷新中…反馈；记住自动刷新开关与间隔（localStorage + ?interval= 深链）
- 主统计页：后台静默刷新连续失败时连接指示转实时刷新中断告警；记住用户手动调整的刷新间隔
- 设置页：新增 config_test 端点 + 独立测试连接按钮（用弹窗内未保存凭据测连接，不落盘）；
保存按钮加保存中…防重提交；登录失败不清旧 token
- 抽取页：重置结果加二次确认；新增复制名单按钮（两列制表符分隔，可粘到微信/Excel）
- 修复看板预先存在 JS 语法错误（少一个右括号导致整页 JS 失效）
