System Design for Multi-Agent Foresight

Design the architecture for a multi-agent system that can perform foresight-driven urban infrastructure planning. Specify the roles of at least four distinct agents (e.g., Data Analyst, Infrastructure Planner, Risk Assessor, Policy & Ethics), their communication protocols using AutoGen, and how they will integrate with a multimodal semantic memory system using a vector database. Detail how Command R+ via Amazon Bedrock will be used by each agent for their specific reasoning tasks and how agent debate will resolve conflicts or optimize decisions.
