+This spec was inspired by https://github.com/microsoft/CCF/blob/main/tla/consensus/abs.tla.
+
+This spec has a machine-closed fairness constraint, which differs from the the CRDT and
+ReplicatedLog examples.  However, this spec assumes that a server can consistently read the
+state of all other servers, which is clearly not a realistic assumption for a real
+distributed system.  A real system would rely on some messaging protocol to determine the
+lag between servers (compare Raft).
