Check it yourself
Every figure above is read from /glassbox/polygon_split_crosscheck.json, the
artifact the engine wrote. Nothing on this page is typed by hand: the page is generated from that
file, so a figure that moves in the artifact moves here and a figure that is not in the artifact
cannot appear here at all.
