Qr-Hint: Formally Verified and AI-Explained SQL Tutoring
Summary: Qr-Hint formally finds the smallest syntactic edit that restores semantic equivalence between an incorrect and correct SQL query, avoiding test-case dependence. It uses AI to turn verified diagnoses into answer-preserving hints for learners and teaching staff. (summarized by gpt-5.6-luna on Aug 28 2026)
