The flank rule still admitted wedges beside HALF-course steps (island columns differ by the kit's 0.5/0.25 quarter blocks), which grew staircases of exposed triangle profiles along terraced shoulders, and let diagonals sit above part-lowered backs. The law is now binary per side: FLUSH (neighbor top at own level or higher, <=0.01) or OPEN (clean full-course drop, >=0.99); any in-between step disqualifies the cell. A slope needs exactly one open side; a diagonal exactly two adjacent opens with the between-corner open. Everything else keeps the cube.
