Shedding Light on Opaque Application Queries
Summary: UNMASQUE, an active-learning, non-invasive extractor, unmasks hidden SQL queries in applications by observing results from mutated/generated data. Optimizations trim overhead; evaluations on hidden/imperative variants show accurate, efficient recovery of a basal warehouse-query class. (summarized by gpt-5-nano on Feb 09 2026)
