# Data Provenance Data provenance records where a datum came from, when it was created or observed, how it changed, which system or person supplied it, and what transformations or custody steps occurred. ## Notebook evidence [[Scanned_20260730-1845]] repeatedly asks which identity, company, certificate, device, or institutional repository makes a record authoritative. PDF page 27 requests historical company data; pages 39–43 preserve insurance, travel, account, and education evidence; pages 63–67 map legal, court, public-health, finance, and scientific repositories. ## Evidentiary role Provenance prevents a visual interface state, copied label, allegation, or later interpretation from being mistaken for the original record.
