- **nginx**: routes requests — `/api/*` to the Gateway, LangGraph streaming endpoints to LangGraph directly, and everything else to the frontend.
- **Frontend** (Next.js + React): the browser UI. Communicates with both the Gateway and LangGraph.
- **Gateway** (FastAPI): handles API operations — model listing, agent CRUD, memory, extensions management, file uploads.
- **LangGraph**: the DeerFlow Harness runtime. Manages thread state, agent execution, and streaming.
