In line 1691, shouldn't it be if !inst.lb.possibleQuorum[q] instead of. if !inst.lb.possibleQuorum[tpar.AcceptorId]?
Reasoning-
Line 1686 sets inst.lb.possibleQuorum[tpar.AcceptorId] = false.
Hence, the if condition in line 1691 will be always true. So the value of notInQuorum will be always r.N. This means if one replica rejected the try-pre-accept then notInQuorum will be directly set to r.N and then the condition in line 1695 will be always true. And hence the replica will move to phase 1 all the time. So code in lines 1700 to 1715 are never executed.
