ts-combo-contested-claims-claim-level ts-claim-cf1-contested-claim-level ts-claim-so1-contested-after-open-retrieval ts-concept-polarity-concordance In open-retrieval claim-verification corpora the contested fraction among claims with two or more polar evidence documents is about 0.2, independent of the number of documents and of domain; closed citation-built corpora show about 0 by construction, not because scientific claims are uncontested. A fourth open-retrieval corpus with >=2 polar documents per claim whose contested fraction falls outside 12-28% or whose trend in k has z > 1.6; or SciFact-Open's contested fraction rising above 35% as evidence per claim grows; or independence overprediction below 2x in any such corpus. ready_to_test 2026-09-02T15:10:00Z
