PROPOSAL (synthesis, not a tested standard): require eight items before saying a world model worked on a job: system and version, production date, task, inputs, outputs used in the final cut, a comparison baseline that was actually run, who measured and who wrote the claim, and what was not measured. Mapping the cases found: none of the generative cases meets items 1, 5 or 6; the only case with a run alternative (DOSENMUTTER) is not a world-model case. Until a case meets the checklist, an agent should say 'vendor reports' and not 'it worked'.
