Sorry, there are in fact three distinct solutions - found a bug in my previous code

comment Closed-form solution to 3D vector rotation problem
Thanks, I added a recap panel and edited the picture. The z axis is still flipped, mainly because showing angles arcs greater than $\frac{\pi}{2}$ makes the drawing very cluttered and confusing. However, that should only make a difference when determining the signs of the rotation elements, conceptually it should not have any importance for understanding the problem

I see, yes that makes sense. So that question is, when do we find a "bump" in the product?

sure, I'll try, let me know if I can clarify further - I'm still trying to formalise it properly in my head!
