+  }
+}
+```
+
+### Message Types
+- `analyze_request`: Web to backend for analysis jobs
+- `train_request`: Web to backend for training jobs
+- `config_update`: Web to backend for configuration changes
+- `get_config`: Web to backend to retrieve current config
+- `register`: Worker to backend registration
