After the first version's reviews, the person asked whether its title was accurate and, when the agent judged that it overstated the findings, asked for this correction of the title and of what the reviews found. Every other proposal, from the plan's rules to the record of departures and this version's changes, was the agents', and the person accepted them. No person reviewed the extractions, the code, the results, or the paper."
