Read the evidence

Every imported value has a source, version and locator. Nulls are not zero. Published monthly prices are not transactions. Two-month views require both months unless you explicitly enable a partial view. National figures are never allocated to states. Unknown publication dates are excluded from historical as-of views. UCDP counts documented organized-violence events, not all crime. A checksum proves byte integrity, not factual truth. Community evidence stays private until independently reviewed and moderated.
