+been inverted since 2023: it demanded the marching-cubes ambiguous face pattern instead of
+forbidding it, so almost no cell reached the reproduction test and a floor roughened by one pass
+and re-cut flat by a later one stayed at its finest level for the life of the tree. 128 of the 256
+corner masks now pass, the 1e-9 reproduction test behind the gate is unchanged. On a 1000-move CL
+replay the node count drops 17% and the peak working set 8%. Because folds are now routine, the
+meshed-geometry writer and the fly-piece remover tolerate a child array folded away under them
+while a cut runs on another thread — a snapshot taken mid-cut stays torn, but no longer crashes.</li>
