多角色账号按 All > College > Class > Self 自动取最高权限。

学院管理员限制在所属学院。
辅导员通过稳定账号 ID 绑定行政班，避免重名串班。
教师只能访问本人档案、授课课程和所授课学生。
学生只能访问本人档案及所在班级课程。
教师/学生角色会自动校验并绑定工号或学号档案。
超级管理员可在用户页面调整角色、学院、工号/学号，并预览生效后的数据范围。

 当前已实现系统登录与角色权限、基础数据、用户管理、教师档案、学生档案、课程库、培养方案、教学任务、排课课表和首页统计。人员及课程列表支持组合筛选、服务端分页和完整增删改查；培养方案支持课程模块、专业年级版本、复制新版本、发布锁定和旧版本归档；教学任务支持学期课程开设、多教师、合班、容量校验、发布与结课；排课支持单双周、周次节次、教室容量、教师/行政班/教室冲突校验和版本化发布。
