    In a microservices world, your API *is* the product. Bad API design isn't just ugly code; it's architectural entropy. The "Contract-First" Enforcer forces Large Language Models to stop being "code generators" and start being "specification designers"

    The symfony/workflow component has long been one of the framework’s most powerful, yet underutilized, gems. It allows developers to decouple business process logic from entity state, transforming complex “spaghetti code” status checks into clean, visualizable directed graphs. In this article, we will build a robust Multi-Signature Approval System for a FinTech application. We will explore how to configure weighted transitions, implement the entity logic, and verify the flow with rigorous testing.
