[System/Component] Architecture

Purpose

This document provides comprehensive architectural documentation for [specific system/component] within the Sirius project. 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
