So I understood you correctly before -- it is a sequence switch :-D

I started writing that I am not convinced, but then you convinced me, 
so I delete everything in "unconvinced" state :-D

Sure.

I sense here, that you calculated B->D from exclusion. This is 
interesting mathematical challenge, but even without much thought I 
think it is not doable because there are cases when you get clash. 
I.e. you end up with mutually depend exclusions.

Unless you say, that we try first exclusions, and for all clashes we 
compute sequence from geometry + take-first decision.

Hmm, I am kinda more convinced to sequence switching.

Nah, this one can be fixed :-) Btw. spatial alg. must also have bias.
