Description: A Bayesian analysis for Q methodology, alongside the
        classical one. Models the forced Q sort as an ordered partition
        of the statements through an exact rank-order likelihood (the
        design quotas fix the partition margins, so the likelihood of
        the observed sorting event is exact), fits it by a
        parameter-expanded Gibbs sampler in R with no compiled code and
        a convergence gate on rotation-invariant functionals, resolves
        rotational ambiguity via the MatchAlign post-processing of
        Poworoznek et al. (2025) <doi:10.1214/25-BA1544>, and returns
        the familiar Q tables as posterior summaries: credible
        intervals for bounded participant loadings, flag probabilities
        with an explicit unclassified state, quota-respecting factor
        arrays, distinguishing and consensus statements judged against
        a posterior critical difference and a grid-width equivalence
        region, one posterior false-discovery rule for all published
        claims, and a two-signal posterior-predictive workflow for the
        number of factors.
