Legacy Modernization with GitHub Copilot

Most GitHub Copilot writing assumes a clean repo and a fresh problem. Real enterprise work is a system that has been running for a decade, whose original authors have left, whose business rules survive only as a strange if branch nobody dares delete. This series is about that system. It starts with the blueprint for an AI development team, then goes deep on each role in turn: extracting the knowledge the code never held, pinning current behaviour before changing a line, reviewing security without trusting the review, and finally the orchestration that decides who does what and where a human signs their name.
