-The initial two-human written record models offer, acceptance and mutual
-release; compliance with prose and impossibility are player-managed, and spice

+Written records allow two to six human seats to consent and mutually release;
+pairwise nonalliance at offer and acceptance is a conservative provisional
+interpretation, not an explicit publisher ruling on multiparty offers. Prose
