• 你这个现象我已经定位并修了，核心原因是节点匹配和设备映射都有歧义。

已修改：

  - 节点识别优先用 id，只有找不到才回退 code，避免子节点被匹配成父节点
    ServerService.php (/E:/code/php/Xboard-new/app/Services/ServerService.php#L101)
  - 在线设备解析补全 node_key/node_id，并按真实节点键归类
    UserOnlineService.php (/E:/code/php/Xboard-new/app/Services/UserOnlineService.php#L43)
  - 用户端流量日志设备映射改为按 node_key 精确匹配
    StatController.php (/E:/code/php/Xboard-new/app/Http/Controllers/V1/User/StatController.php#L43)
  - 管理端同样改为按 node_key 映射
    StatController.php (/E:/code/php/Xboard-new/app/Http/Controllers/V2/Admin/StatController.php#L270)

  说明：

  - 这次不涉及数据库结构变更，不需要 migrate。
  - 对管理后台现有统计接口兼容，不会破坏原有 u/d/record_at/server_rate 显示。
  - 旧的历史日志如果之前已经按父节点入库，不会自动改名；新流量会按修复后的逻辑记录。
