Maintainability & Modifiability

📄️ Modularity and Encapsulation Principles

Apply modularity principles, information hiding, and sound module design to reduce coupling, improve cohesion, and enable independent system evolution.

📄️ API Contracts and Backward Compatibility

Design API contracts, implement semantic versioning, detect breaking changes, and evolve schemas while maintaining backward compatibility with existing clients.

📄️ Code Health Metrics and Refactoring Strategy

Track code health with cyclomatic complexity, coupling metrics, and technical debt; implement refactoring strategies and automate code quality gates in CI/CD.
