Description: Tools for detecting, decomposing, and testing temporal change in
    repeated binary decision systems. Decomposes each change in the decision
    rate into inflow (uptake) and outflow (reversal) through the
    marginal-transition identity, separates net change from gross turnover,
    and splits aggregate change into within-group and composition components
    with a symmetric midpoint decomposition. A unit-level cluster bootstrap
    gives intervals for every component and a global test of process
    stability with family-wise-adjusted contrasts and simultaneous confidence
    bands. Also provides prevalence and transition drift summaries, entropy
    trends, group-differential drift, change-point diagnostics, robustness and
    sensitivity analyses, an integrated audit, and a simulator for stable,
    marginal, masked, abrupt, group-masked, and composition-change scenarios.
    Complements the 'decisionpaths' package. Applications include algorithmic
    audit, AI governance, education, health, and organisational research.
