Combined Approximations for Uniform Operational Consistent Query Answering

Summary: Uniform approximation for operational CQA via revised repairs; combined-complexity for self-join-free, bounded-HTW conjunctive queries. Introduces SpanTL, and uses tree-automata results for efficient approximations; hardness if self-join or HTW bound is relaxed. (summarized by gpt-5-nano on Feb 09 2026)
