ImpactGate: A merge gate that scores the structural decay AI adds

ImpactGate introduces a way for engineering leaders to quantify and control the structural decay that AI-assisted code changes can add, turning a subjective review issue into a measurable CI gate. For CIOs and technology teams, this means faster delivery from AI tools can be balanced with stronger governance over technical debt, maintainability, and long-term delivery risk by flagging or blocking changes that overload complex code areas. IT organizations that adopt this approach can better preserve software quality, reduce refactoring surprises, and make AI coding more scalable across enterprise development teams.
