The Fact & Gap Checker systematically reconciles live grounded research against a brand's stored claims by comparing cited web findings directly against native model recall. It updates matching recalled claims to verified or contradicted statuses while attaching source URLs as evidence, and catalogs unmentioned facts as entries marked as gaps in training memory. Crucially, the system protects human-vetted claims from automated overwriting and ensures research findings cannot self-validate as authentic recall without unprompted parametric confirmation.
