I deactivated this puzzle a while ago due to the comment below, but recently went back and did a rigorous test-solve of it. In my opinion, this puzzle does not require bifurcation or excessive case-checking, however if you fail to ask the right logical question then indeed that may be the only way forward -- as with all puzzles.

This puzzle features a number of very sophisticated small steps, but some of them require so much case-testing they're borderline - if not outright - bifurcation. I'm astonished so many people have solved it.
