Data Coordination: Supporting Contingent Updates

Summary: Introduces data coordination for contingent sources C when independently maintained bases B change, using declarative mappings without constraining B. Novel two-stage algorithms perform view differencing and translate resulting changes into updates on C, validated on real workloads. (summarized by gpt-5.6-luna on Jul 24 2026)
