What's happening in this scenario is that B is not getting any revs

replication both ways, then your nodes will be consistent (assuming
they accept the same set of updates as valid).
If you have > 2 nodes then that is no longer true. Consider three
nodes A, B and C where
A: has a validation function F
B: a document that is invalid under F
Replicating B -> C, A -> C is different than A -> C, B -> C, and there
is no global steady state that can be reached.
Without these non-functional additions, A, B, C will tend to a global
steady state assuming full replication coverage, regardless of
ordering. At least that's what I assume from the wiki statement about
the determinism of conflict resolution. Have I made the wrong
assumption about that?
