Initial Agent Design and Modeling Plan

Based on the concept of 'Model-First Reasoning', design the architecture for your supply chain optimization agent. Define the explicit internal model(s) the agent will construct (e.g., current inventory state graph, demand prediction model, cost function representation). Outline the LangGraph states and edges required to implement the iterative reasoning and decision-making process for a multi-tier supply chain. Specify how Llama 3.3 will be prompted to interact with and update this internal model.
