System Dependency Graph

This document illustrates the relationships between the core systems of Atlas and their interdependencies. This serves as a blueprint for understanding how different components interact and rely on each other.

Core Services Layer Dependencies

The Core Services Layer provides fundamental capabilities that all other components depend on:
