Volume monotonicity under crossing changes for alternating hyperbolic links

Let $K$ be an alternating hyperbolic knot or link, and let $K'$ be obtained by changing any proper subset of crossings of $K$.

Volume monotonicity conjecture.

$$\operatorname{vol}(K')<\operatorname{vol}(K).$$

This conjecture predicts that changing any proper subset of crossings strictly decreases hyperbolic volume. The source presents the claim as a broader conjecture of which the weaving-knot volume bound is a special case and test; its resolution is not indicated here.
