Of 8 dimensions, 6 showed perfect agreement (scores of 1 each). The only non-trivial differences were: (1) scientific_premise where A scored 4 and B scored 3—averaged to 4, and (2) study_design where A scored 1 and B scored 2—averaged to 2. Both differences were within the ≤1 threshold, so averages were taken without flagging. No discrepancies required escalation. Cohen's kappa is not calculated because the ordinal scale and document-type constraints produce highly asymmetric marginal distributions that render the metric uninformative. Overall, evaluators demonstrated high consensus in recognizing this document as a non-empirical hypothesis paper lacking primary research rigor elements.","overall_agreement":"high","reconciled_scores":{"sabv":{"score":1,"a_score":1,"b_score":1,"a_evidence":"No mention of sex as a biological variable.
