A New Basis for the Weak Instance Model
Summary: New weak-instance model treats nulls as mere lack of information (not existent-but-unknown), enabling logical theories without universal quantifiers while preserving dependency and query-answering properties. Drops the universal-instance assumption and gives principled semantics for universal-relation interfaces rather than heuristic rewrites. (summarized by gpt-5-mini on Feb 09 2026)
