Citation Discipline Score

Citation Discipline measures how rigorously a source backs each factual claim with a verifiable external source. High-discipline sources cite primary evidence inline; low-discipline sources opine without sourcing. AI engines weigh discipline heavily — uncited claims are increasingly skipped by retrieval models.
