Cooperative Update Exchange in the Youtopia System

Summary: Youtopia’s cooperative update exchange combines a deterministic chase with user-controlled mapping repair, allowing cyclic mappings while preserving correctness. It defines final-state and conflict serializability for update interference and presents an optimistic enforcement algorithm with abort reduction. (summarized by gpt-5.6-luna on Jul 24 2026)
