ClaimBound Evidence

Where is the evidence? ClaimBound turns a narrow public claim about AI, ML, data or software into a small evidence card: frozen protocol, hashed sources, an exact result status, a claim boundary and a reproduction level.

It is not a model leaderboard, a hosted scoring service or a certification authority.

Reading the results honestly

• A green card means one narrow claim passed under one frozen protocol, nothing more.
• Most public cards are still SINGLE_OPERATOR and not independently reproduced. Independent reruns are the signal that matters most; see common misreadings.
• Many cards were produced with AI assistance (execution_mode: AUTOMATED_AI_ASSISTED); the field is part of every card and a validated card is judged by its protocol, hashes and boundary.
• Negative, blocked and insufficient-coverage outcomes are published like positive ones.
