A Dichotomy in Consistent Query Answering for Primary Keys and Unary Foreign Keys
Summary: Dichotomy for CERTAINTY(q) with primary keys plus unary foreign keys under symmetric-difference (XOR) repairs for self-join-free conjunctive queries: either admits a FO rewriting or not. Provides precise structural characterization separating the two cases. (summarized by gpt-5-mini on Feb 09 2026)
