A group whose order rules disagreed was refused as "its order contradicts
itself" with only the member ids: nobody could see which rules clashed or
what to write to resolve it. The controller now resolves rules by
precedence (hq ADR 0249) and answers, per pair, the rules it won over, and
per contradiction no precedence resolves, both rules and how to declare
the order. mesh-delivery keeps both, lists them in groups and the plan
note, and refuses a group by those words; a cycle through more members
names the pairs in it. An older controller's answer reads as before.
