Across the sources read, validation of automatic persona/voice measures is thin: PersonaScore had five experts and 1,500 ratings (kappa 0.71; mean Spearman 75.1%); the consistency judge of Abdulhai et al. agreed with humans more (kappa 0.552) than humans agreed with each other (0.303); the persistent-persona judge was checked by one author (kappa 0.65, 250 ratings); RoleBench reports GPT-4 and human win rates without an agreement statistic; the Distinction Score has no human check on generated lines. An evaluation protocol that combines blind attribution, cast-level distance, drift probes and a validated judge is proposed; no source documents it as a whole.

Curator qualifications: Validation of automatic persona measures is thin (small expert panels; judge-human agreement exceeding human-human in one study); the proposed evaluation protocol has not been run.

Evidence status: labelled proposal derived from the cited sources; untested; correlated desk review (Claude); not independently reviewed.
