+### OpenClaw 元数据 enrichment
+
+当 OpenClaw 插件通过 `POST /openclaw` 推送元数据后，Monitor 会在后续的心跳上报中自动将这些信息附加到遥测数据中：
+
+- `openclaw_version` — OpenClaw 运行时版本
+- `plugin_version` — 插件版本
+- `agents` — 代理列表
+
+如果插件从未推送过元数据，这些字段会被省略，心跳上报完全不受影响。
 
 **重要**：桥接端口是可选的。如果 `MONITOR_PORT` 为 0 或未设置，桥接服务不会启动，Monitor 的心跳上报功能完全不受影响。即使桥接服务启动失败，心跳上报也会继续正常工作。
