Conjecture on kk-Antichains in the Unit Cube

A subset AA of the pointwise-ordered cube [0,1]n[0,1]^n is a kk-antichain when it meets every chain in at most kk points. The conjecture concerns the largest possible (n1)(n-1)-dimensional Hausdorff measure of such a set; it is settled here, following work of Janzer.
