- * 重要设计说明（符合业界最佳实践）：
+ * 设计说明：
  * ===========================================
- * - handle() 方法在事务内执行，只负责数据同步（synced_adoptions 表）
- * - 返回 AdoptionSyncResult，包含需要计算算力的认种ID
- * - 算力计算（calculateForAdoption）必须在事务提交后单独执行
- *
- * 为什么不能在事务内调用 calculateForAdoption：
- * 1. calculateForAdoption 内部使用独立的数据库连接查询数据
- * 2. 在 Serializable 隔离级别下，内部查询无法看到外部事务未提交的数据
- * 3. 这会导致 "Adoption not found" 错误，因为 synced_adoptions 还未提交
- *
- * 参考：Kafka Idempotent Consumer & Transactional Outbox Pattern
- * https://www.lydtechconsulting.com/blog/kafka-idempotent-consumer-transactional-outbox
+ * - handle() 方法100%同步数据，不跳过任何更新
+ * - 算力计算只在 status 变为 MINING_ENABLED 时触发
+ * - 算力计算在事务提交后执行（避免 Serializable 隔离级别的可见性问题）
