QFix: Demonstrating Error Diagnosis in Query Histories

Summary: QFix is a query-centric error-diagnosis framework that infers faulty queries to explain and repair data discrepancies, not patch data directly. The demo benchmarks transactional data, injects query errors, and compares QFix to decision-tree baselines. (summarized by gpt-5-nano on Feb 09 2026)
