Crossing-change invariance conjecture for lifts of tree-type webs

About 4 years old · traced to

Let G~\tilde{G} and G~′\tilde{G}' be tangled tree diagrams related by crossing changes, and let G∈Treesp4,ΣG\in\mathsf{Tree}_{\mathfrak{sp}_4,\Sigma} be a tree-type elementary web. Crossing-change invariance conjecture. If G~\tilde{G} is a lift of GG, then G~′\tilde{G}' is also a lift of GG. The claim would make the lift property independent of the chosen crossing data within a crossing-change class; the source gives no resolution.
