Description: Implements Metric-T, a permutation-based diagnostic that flags
    when the reported direction of a group difference in
    electroencephalography (EEG) functional connectivity depends on the
    choice of metric. Direction consistency (DC)
    converts the weighted phase lag index (wPLI) and magnitude-squared
    coherence (MSC), both derived from the same cross-spectrum, into the
    percentage of channel-pair features for which one group exceeds the
    other; Metric-T is T = DC(wPLI) - DC(MSC). Significance is assessed by
    aligned label permutation with marginal and Westfall-Young max-T
    multiplicity control. For small samples the reference set is enumerated
    completely: exact two-group tests, the complete two-group labelling
    space (in which cut-points, exclusions and batches are located on one
    distribution), and a stratified exact test for a continuous covariate.
    Core functions use base R only; a 'shiny' graphical interface is
    included. Method: Kimura (2026) <doi:10.1016/j.neuri.2026.100286>.
