This PR contains some technical machineries for reasoning about diamond and fairness properties about the distributed algorithms introduced in #556:
CanReachVia.leandefines the notion of reachability via a subset of processes and proves some of its properties, including some diamond properties.FairScheduler.leancontains a technical machinery for constructing fair executions, which will be used in formalizing some arguments which were either only hinted at or completely glossed over in Völzer's paper.Zulip discussion:
