Product Decisions This Supports

Enforces architectural standards through automated tests, reducing technical debt and ensuring consistency as the codebase evolves.
Supports build vs buy decisions by providing a ready-to-use solution instead of custom scripting for architecture validation.
Key use cases include maintaining layered architectures (e.g., hexagonal, clean architecture) in medium-to-large applications, and validating dependency rules during refactoring or feature expansion.
Aligns with roadmap goals for long-term maintainability, especially when scaling teams or migrating legacy systems to modern patterns.

When to Consider This Package

✅ Adopt when:
- Your project has a defined architecture (e.g., strict layer separation, bounded contexts) requiring enforcement.
- Team size exceeds 5 developers, and manual code reviews struggle to catch architectural violations.
- You already use PHPUnit and CI/CD pipelines for testing.
❌ Look elsewhere when:
- The project is a small prototype or monolithic script with no formal architecture.
- You need deeper static analysis (e.g., type checking, code smells)—use PHPStan or Psalm instead.
- Your test suite doesn’t use PHPUnit (e.g., Pest, Codeception), as this package is PHPUnit-specific.

Executives: "This tool automates validation of our application’s structure, preventing costly architectural drift that leads to bugs and delays. By catching violations early in development, it reduces technical debt, accelerates feature delivery, and ensures long-term codebase sustainability—directly impacting ROI through lower maintenance costs and faster time-to-market."
Engineering: "Seamlessly integrates with PHPUnit to enforce architectural rules (e.g., layer dependencies, namespace constraints) as part of CI. Lightweight, MIT-licensed, and easy to adopt—replacing manual code reviews for architecture compliance and ensuring consistent standards across the team."
