 后端启动时会自动拉起本地 Embedding 服务（Octen-Embedding-0.6B，端口 17997），首次启动会下载模型。如需关闭本地 Embedding，设置 `USE_LOCAL_EMBEDDING=0`。

 On startup, the backend automatically launches a local embedding service (Octen-Embedding-0.6B on port 17997). The model is downloaded on first run. To disable local embedding, set `USE_LOCAL_EMBEDDING=0`.
