+### `api.runtime.nodes`
+
+List connected nodes and invoke a node-host command from Gateway-loaded plugin
+code. Use this when a plugin owns local work on a paired device, for example a
+browser or audio bridge on another Mac.
+
+```typescript
+const { nodes } = await api.runtime.nodes.list({ connected: true });
+
+const result = await api.runtime.nodes.invoke({
+  nodeId: "mac-studio",
+  command: "my-plugin.command",
+  params: { action: "start" },
+  timeoutMs: 30000,
+});
+```
+
+This runtime is only available inside the Gateway. Node commands still go
+through normal Gateway node pairing, command allowlists, and node-local command
+handling.
