+/// ============================================================
+/// 【课堂习题 · 数据加载】（1:1 迁移 Vue exerciseLoad.js）
+///
+/// - loadStartOvercome：edit 模式，GetRecordData + GetListByRecordQuestion，
+///   解析题目、追加 sort、补 hasOptionChildrenQuestion、挂学科 id；
+/// - loadSubmitReport：view 模式，GetSubmitReport，错题模式过滤重排。
+///
+/// 调试：loadStartOvercome 在接口返回后会（仅 kDebugMode）追加
+/// assets/mock/class_exercises_edit.json（取自 Vue exerciseLoad.js）。
