+# iotlcm-worker-svr
+
+Dedicated RabbitMQ consumer service for IotLCM asynchronous work.
+
+## Consumers
+
+The service always registers these business consumers when RabbitMQ is enabled:
+
+- `iotlcm.traffic_usage.daily.retry`
+- `iotlcm.traffic_usage.monthly.retry`
+- `iotlcm.work_order.auto_close`
+
+For local Admin-to-Worker integration checks, set `workerDiagnostic.enabled: true` to
+register `iotlcm.worker.diagnostic`. Diagnostic messages are logged and acknowledged;
+they do not access MySQL, TDengine, or Upstream. The diagnostic consumer is disabled
+in the default and build configurations.
+
+## SIM status synchronization
+
+Status sync uses run-scoped queues and durable outcome counters. The optional
+`simStatusQueueSync.redisKeyPrefix` setting controls the Redis key prefix used by
+these queues.
+
+
+## 角色权限同步
+
+配置 `roleSync.enabled: true` 后，由本服务独立接管管理后端的持久化角色权限任务。默认关闭；启用前需先完成数据库迁移，并移除旧管理后端的执行入口。
