Limits And Trust Boundary

The API is read-only and public. Use AnchorFact only when answer_policy.can_answer_with_anchorfact is true, then cite claims returned by /api/context, /api/evidence, or /api/cite. For live prices, current events, local conditions, or personalized decisions, use external authoritative sources.
