Mirrors [[io.github.libtmux.exception.CardinalityException CardinalityException]]'s two leaves losslessly, including the match count Java's own `MultipleMatches.atLeast()` carries — dropping it would be exactly the hand-authored lossy projection this facade's opaque handles exist to make impossible everywhere else.
