## Overview
This directory contains foundational concepts and theoretical documentation for the cognitive modeling system. While the [[knowledge_base/cognitive/cognitive_science|Cognitive Science Knowledge Base]] contains the comprehensive cognitive science theory, this directory focuses on the implementation and documentation aspects of these concepts.
