-**Legend:**
 - Live Platform Client: Live platform client (e.g., Bilibili) sends comments to the proxy (formatted as text-input)
 - Frontend UI: Front-end interface also sends user input and control messages to the same proxy
 - /proxy-ws: Core proxy endpoint, receives all messages and handles forwarding and broadcasting
 - WebSocketHandler: Processes messages and interacts with AI
 - AI Agent: Generates responses
 - AI responses are ultimately broadcast via the proxy to all connected clients (including the frontend and live platform client)
 
-**Core Requirement:** For live comments to be processed by the AI, and for AI responses to be correctly displayed in the frontend, **all clients (including the frontend UI and live platform client) must connect to the same `/proxy-ws` endpoint**.
