ARCHITECTURE documents serve as authoritative sources for system design, component relationships, data flow, and structural decisions. ## When to Use - **System Design**: When designing new systems or major components - **Integration Planning**: When connecting systems or components - **Code Review**: When reviewing implementation against architectural decisions - **Onboarding**: When bringing new team members up to speed - **Refactoring**: When making significant structural changes ## How to Use ### Quick Overview 1. **Start with the System Overview** to understand the big picture 2. **Review the Component Architecture** to understand individual parts 3. **Follow the Data Flow** to understand how information moves 4. **Check the Integration Points** to understand connections 5. **Reference the Design Decisions** for context on why choices were made ### Architecture Patterns ```mermaid graph TB A[Component A] --> B[Component B] B --> C[Component C] C --> D[Component D] D --> A ``` ## What It Is ### System Overview [High-level description of the system, its purpose, and key characteristics] ### Architectural Principles -
