  *     3. OrderMain (挂号单) → CANCELLED（已取消）
  *     4. RefundLog         → SUCCESS（退款成功）

- *   解决思路：
+ * 关键修复点（Bug #503）：
- *     - 将退号业务放在同一个 @Transactional 方法中，确保原子性。
+ *   住院发退药时，发药明细（DispensingDetail）与发药汇总单（DispenseSummary）在业务层面的
- *     - 使用统一的枚举常量，避免硬编码导致的状态不一致。
+ *   状态更新时机不一致，导致发药明细已写入但汇总单仍保持旧状态，产生业务脱节风险。
+ *   解决方案：
+ *     1. 将发药明细写入与汇总单状态更新放在同一个事务中，确保原子性。
+ *     2. 在写入明细后立即调用汇总单的状态更新方法，并在同事务内完成。
+ *     3. 为防止并发导致的汇总单状态脏写，使用 SELECT … FOR UPDATE 锁定对应汇总单记录。
