{"judgments":[{"pair_id":"E13Q032","reason":"B applies event primacy directly to passage-grounded narratological disagreement, with explicit distinctions among occurrence, report, disclosure, and inference. A is unusually measurable but its apparatus is expensive, behavior-perturbing, and only weakly connected to interpretive reading; physical traversal should not be mistaken for literary uptake.","scores_a":{"causal_coherence":3,"contrivance_risk":5,"incremental_portfolio_value":4,"operational_specificity":5,"practicality":2,"structural_fidelity":4,"testability":5},"scores_b":{"causal_coherence":5,"contrivance_risk":3,"incremental_portfolio_value":3,"operational_specificity":5,"practicality":4,"structural_fidelity":5,"testability":4},"winner":"B"},{"pair_id":"E13Q027","reason":"Both instantiate governed fast-to-slow transfer well, but B adds a genuinely distinct local cumulative-memory case with explicit controls, harvest, validation, and conservation-history integration.
