What then would you specify as the clearly defined storage fault model for non-Byzantine protocols such as Paxos/RAFT that rely on stable storage for correctness?
Anything is possible with Byzantine faults, on the specific failed node. It will not remember voting, it will not remember to vote, it will not remember its identity, etc. PAXOS/Raft are not tolerant to a minority of nodes exhibiting those kinds of faults, only to a minority of nodes being unreachable or partitioned.
Remember that the Byzantine generals had traitors among them, not merely communication issues.
