  * 修复 Bug #505、#503、#506、#561 等。
  *
- * 关键修复点（Bug #506）：
- *   门诊诊前退号后，涉及的多张表（order_main、order_detail、schedule_slot、schedule_pool 等）状态未统一
- *   与生产环境（PRD）定义不符，导致前端显示状态错误、后续排班冲突等问题。
- *
- *   解决思路：
- *     1. 将退号（退款）业务全部放在同一个 @Transactional 方法中，确保原子性。
- *     2. 统一使用 {@link OrderStatus#CANCELLED} 作为退号后医嘱主表的状态。
- *     3. 对应明细表（order_detail）状态同步更新为 {@link OrderStatus#CANCELLED}。
- *     4. 释放已占用的号源：将 schedule_slot.status 设为 {@link ScheduleSlotStatus#AVAILABLE}，
- *        并将 schedule_pool.used_count -1（若大于0）以恢复号源库存。
- *     5. 记录退款日志（refund_log），确保审计完整。
- *
  * 关键修复点（Bug #561）：
- *   医嘱录入后，总量单位（totalUnit）显示为 “null”。根因是创建 OrderDetail 时未从诊疗目录
- *  （CatalogItem）中读取并写入单位字段，导致前端渲染时取到空值。
+ *   医嘱录入后，总量单位显示异常，显示为“null”。根因是 OrderDetail 在保存时
+ *   未正确从诊疗目录（CatalogItem）读取并写入 totalUnit 字段，导致前端取到 null。
  *
  *   解决方案：
- *     1. 在保存医嘱明细（OrderDetail）时，显式把诊疗目录的计量单位（catalogItem.unit）复制到
- *        OrderDetail.totalUnit 字段。
+ *   1. 在创建 OrderDetail 前，确保通过 catalogItemId 查询到对应的 CatalogItem。
+ *   2. 将 CatalogItem 中的 totalUnit（或 unit）写入 OrderDetail.totalUnit。
+ *   3. 若 CatalogItem 为 null 或 totalUnit 为 null，抛出业务异常，防止脏数据写入。
+ *   4. 为兼容历史数据，若 CatalogItem 中的 totalUnit 为空，仍使用旧字段 unit 作为回退。
+ *
+ * 关键修复点（Bug #506）：
+ *   门诊诊前退号后，系统需要同步更新以下几张表的状态，使其与 PRD 定义保持一致：
+ *     1. OrderMain.status          → OrderStatus.CANCELLED（已退号）
+ *     2. OrderDetail.status        → OrderStatus.CANCELLED
+ *     3. ScheduleSlot.status       → ScheduleSlotStatus.AVAILABLE（号源恢复为可预约）
+ *     4. SchedulePool.status       → ScheduleSlotStatus.AVAILABLE（对应的号池状态同步）
+ *   之前的实现仅修改了 OrderMain，导致后续查询出现状态不一致的情况。
+ *
+ *   解决方案：
+ *   在取消诊前挂号的业务入口（cancelPreOrder）中，统一使用上述四个状态常量进行更新。
+ *   同时记录退号日志（RefundLog），并在同一事务内完成所有表的更新，确保数据一致性。
