System Governance Framework - Technical Architecture

Executive Summary

The System Governance Framework is built on a GitHub-native, automation-first architecture that requires zero additional infrastructure while providing enterprise-grade governance capabilities. The design leverages GitHub’s built-in features (Actions, Security, Issues, Projects) extended through configuration and workflows.

Architectural Principles

1. Zero Infrastructure

2. Configuration-Driven

3. Event-Driven Automation

4. Modular & Extensible

5. Security-First
