Explaining Missing Answers to SPJUA Queries

Summary: Missing-answer explanations for SPJUA queries via a source-data-driven framework; algorithms yield correct, finite, and, when possible, minimal explanation sets. Artemis implements this approach for query debugging; experiments show explanations produced quickly enough for practical developer use. (summarized by gpt-5-nano on Feb 09 2026)
