consistency-gate

Check whether a claim contradicts a known set of facts. Extract subject-predicate-object triples from a natural-language statement (or pass a raw triple) and check each against a grounded fact store. Returns an auditable receipt with a verdict of consistent, contradicts, or unverifiable, plus every conflict it found, never a bare true/false. Advisory and read-only: it flags consistency, it never blocks, decides, or writes for you, and checking a claim never stores it. Includes a deterministic no-LLM triple check for cheap, testable runs, plus a fact-listing tool for transparency. Public demo runs against an open demo fact store, not your data.
