DecidingCommand

The command a decide function is deciding, in its coroutine context while it decides. A command a Wow client sends from there takes nextRequestId as its request id unless its caller gives one, as a saga's derived commands take theirs: a decision decided again after a version conflict sends the same requests again, which their targets answer as repeats rather than run twice. The kernel puts a new one in for each attempt, so the n-th command an attempt sends is the n-th request of every attempt, as long as the decision sends them in order.
