      "description": "A rank-weighted reconstruction reward sounds order-sensitive. A two-gene example tests exactly what its maximum value establishes.",
      "finding": "Reference [A, B] and reconstruction [B, A] both contain the same genes, but in reverse order. In printed Eq.3, their reward is still 1: numerator 1.5, denominator 1.5. A maximum score therefore does not certify identical ordering.",
      "boundary": "This challenges an interpretation of the metric, not the reported model results. The manuscript says \"identical\" without specifying order equality here. No implementation or trained model was tested.",
      "next": "Compare the printed equation with the released implementation, then test whether rank changes matter for the intended biological use. Neither step is completed in this preview.",
      "evidence": "Eq.3 uses reciprocal-rank weights, averages the two weights for shared genes, and divides by reference weights plus weights of generated-only genes. Any permutation of the same unique-gene set of equal length gives 1.",

      "description": "Verification also checks objections. A criticism is unfair if it overlooks an explicit qualification in the source.",
