{"adjudications":[{"pair_id":"E12MQ009","winner":"A","reason":"Crack intersection directly and locally initiates a bounded repair sequence with strong matched controls; B depends more on uncertain ion-exchange selectivity and corrosion-inhibition conditions."},{"pair_id":"E12MQ032","winner":"B","reason":"B partitions independently exhausting treatment functions into coherent, testable modules and evaluates both local substitution and whole-train reintegration with strong rivals."},{"pair_id":"E12MQ048","winner":"A","reason":"A more directly addresses a genuinely binding, contested authority problem while preserving emergency authority and testing legitimacy through a well-scoped shadow adjudication."},{"pair_id":"E12MQ035","winner":"A","reason":"Although both mappings are strained, A gives the gate a concrete bounded decision role with fail-closed operation and direct evidence paths; B relies more heavily on metaphorical authority mapping."}]}
