In high-throughput Rails ecosystems, technical debt often accumulates at the boundaries—where core logic meets volatile third-party drivers or sprawling internal subsystems. As an application matures, the cost of change increases exponentially if the business logic is tightly coupled to specific implementation details. To maintain a decoupled, testable, and resilient architecture,…
