Monotone metric rigidity conjecture for polytopes

Let PRdP\subset\mathbb{R}^d and QReQ\subset\mathbb{R}^e be polytopes with isomorphic edge-graphs. Assume that 0int(Q)0\in\operatorname{int}(Q), every edge of QQ is at most as long as its corresponding edge in PP, and every vertex-origin distance in QQ is at least as large as the corresponding distance in PP. Monotone metric rigidity conjecture. Then PP and QQ are isometric via an orthogonal transformation. This is presented as a stronger conjecture related to the main reconstruction claim, and the source gives no resolution.
