Prelaunch AI Claim Evidence Ladder

Prelaunch AI Claim Evidence Ladder

Treat each model statement as an atomic claim. Give it one current evidence state: rumor, attributed report, controlled preview, publisher announcement, released documentation, accessible artifact, independent evaluation, or observed deployment.

A higher state does not prove every part of a claim. A released model card can establish the publisher's artifact description but not the reader's workload performance. A downloadable checkpoint can establish access but not unrestricted rights. A demo can show one prepared path but not reliability.

Every claim record needs a source, publication date, observation date, product and version, geography or account scope, uncertainty, next verification event, and correction history.
