| t591-dealhub | replication_stopped | IO=False, SQL=True（IO 线程停止，复制中断，数据不再从主库同步） |
无（阈值扫描复核：复制延迟最高 7s（hk8591-slave / mcdb-slave / tw8591-slave，<60s）；连接使用率最高 3.0%（td_master）；慢查询最高 0.01/s（100-master、t8_mysql），均未触发阈值）。
延迟从库说明：本快照中无 sql_delay>0 实例；tw591-slave-lag 为设计延迟从库，当前 seconds_behind_master=0。

注：t591-dealhub 标 0* —— IO 线程已停止，seconds_behind_master 不再增长但复制实际中断；「-」表示无复制上下文（主库/单机）。t8-antifraud BP 命中率 92.8% 偏低（重启约 20 天，属缓冲池预热阶段，暂观察）。
