Design the Multi-Agent Architecture

Design a multi-agent system using LangGraph for the given collaborative task (e.g., supply chain anomaly investigation). Define at least three distinct agent roles (e.g., Logistics, Finance, Compliance) and their primary responsibilities. Architect the graph to include an 'Overseer Agent' node that intercepts and analyzes communications and actions. Describe how agents will communicate and pass information within the LangGraph state. Detail the ethical ontology relevant to your chosen task domain, outlining key guidelines and behavior norms to be stored in the vector database.
