Description: Generates a Report Card for rater reliability on binary
        outcomes from an N x k subject-by-rater rating matrix, on both
        the inter-rater and intra-rater axes. Each panel coefficient is
        positioned on a data-generating-process-calibrated reference
        surface conditioned on the study's rater count, sample size,
        and prevalence, yielding a pooled percentile (the coefficient's
        position within the design's achievable agreement range)
        together with a consistency band on panel quality: the quality
        levels whose sampling distributions are consistent with the
        observed value at that design. The panel coefficients are the
        prevalence-adjusted bias-adjusted kappa (PABAK) of Byrt,
        Bishop, and Carlin (1993) <doi:10.1016/0895-4356(93)90018-V>,
        the first-order agreement coefficient (AC1) of Gwet (2008)
        <doi:10.1348/000711006X126600>, the multi-rater kappa of Fleiss
        (1971) <doi:10.1037/h0031619>, and the observed intraclass
        correlation. A cross-coefficient discordance diagnostic
        (delta-hat) reports the spread of the coefficients' implied
        panel qualities and flags panels for which no single
        coefficient is a stable summary by the spread's percentile on a
        matched null distribution; for such divergent panels the report
        routes to a pairwise PABAK matrix and per-rater sensitivity and
        specificity recovered from the latent-class model of Dawid and
        Skene (1979) <doi:10.2307/2346806>, with the two-rater bounds
        of Hui and Walter (1980) <doi:10.2307/2530508>.
