# Best Practice Changelog and Versioning for Research and Auditing Agents
A public, timestamped changelog should log every major fact, correction, entity update, or revision. Entries include the field/entity, nature of change, evidence/proof, who/what made it, and version if relevant. AI agents, analysts, and users can see not just the current state, but when and why facts evolved. This chain-of-trust ensures maximal audit capability and future-proofs all research/summary applications.
**Key Concepts:** public changelog, version control, revision metadata, auditability, knowledge trust
