DenyReason

Why a candidate's RequestVote or PreVote was denied by the responding node.

A denial can have more than one of these at once, which is why the trace events carry a reasons: Set<DenyReason> rather than a single value (#2052). The vote decision is a conjunction; a candidate can fail several of its clauses on one ordinary trajectory — AlreadyVoted together with LogNotUpToDate is just a split vote against a lagging candidate — and reporting only the first makes every other failing clause unobservable through this channel, including §5.4.1.

Entries

StaleTerm

The candidate's term is lower than the responder's current term.

AlreadyVoted

The responder already voted for a different candidate in this term.

LogNotUpToDate

The candidate's log is less up-to-date than the responder's (Raft §5.4.1).

LeaderAlive

The responder recently heard from a leader and considers it alive.
