The Fact & Gap Checker compares newly discovered research findings against an active ledger of brand claims using a structured JSON decisions schema. When evaluating relationships (confirms, contradicts, or new), it applies strict governance rules to prevent research from grading its own homework: claims that originated purely from research rather than unprompted parametric recall cannot self-validate as "correct" on subsequent discovery cycles and instead retain a gap verdict.

Furthermore, human rulings take permanent precedence over automated assessments, ensuring verified facts remain protected while the system continuously logs evidence, creates new gap claims, and populates supporting sources for every verified or contradicted finding.
