P2 修复（来自审计报告）： - 2.4.4: Server Action 错误消息 i18n 化（attendance/elective 全部 Action） - 2.5.3: 抽取 AttendancePageLayout 组件复用（admin/teacher 页面） - 2.5.4: 抽取 ElectivePageLayout 组件复用（admin/teacher 列表页） - 2.6.3: 考勤月历键盘导航（tabIndex + 方向键 + Home/End + role=grid） - 2.8.2: getStudentAttendanceSummary 分页优化（SQL 聚合统计 + LIMIT 分页） - 2.8.3: resolveCourseDisplayNames 缓存优化（React cache 去重） - 2.1.4: elective data-access 跨模块依赖接口抽象（resolvers.ts 可注入） P2 建议项： - 选课时间冲突检测（parseSchedule + isScheduleConflict 纯函数 + checkScheduleConflict） - 学分上限校验（MAX_CREDIT_PER_TERM + checkCreditLimit） - 考勤/选课数据导出 Excel（export.ts + API 路由扩展） 新增文件： - src/modules/attendance/components/attendance-page-layout.tsx - src/modules/elective/components/elective-page-layout.tsx - src/modules/elective/resolvers.ts - src/modules/attendance/export.ts - src/modules/elective/export.ts 校验： - npm run lint 通过（exit 0） - npx tsc --noEmit attendance/elective/parent 相关零错误
