AutoGen Ethical Companion Architecture

Design an AutoGen multi-agent system for your ethical AI companion. Define roles for agents such as a 'User Proxy', 'Conversationalist', 'Memory Manager (LlamaIndex)', and an 'Ethical Monitor (MCP)'. Outline how Gemini 2.5 Pro will primarily power conversational flow and ethical decision-making, and how Grok 4 Heavy will be invoked for deeper, Graph-of-Thought based reasoning on complex user problems. Detail the interaction flow for a user expressing distress.
