Enum FenceReason 

pub enum FenceReason {
    PeerClaimedEpoch,
    PersistenceFailure,
}

Why a writer is fenced. Both reasons are terminal, but callers must tell them apart (a peer takeover vs. our own failure) rather than parse the message.

Variants

PeerClaimedEpoch

A successor writer claimed a higher epoch; this writer lost ownership.

PersistenceFailure

Our own WAL persistence failed, so in-memory state may have diverged from the durable WAL. The writer must be reopened to replay.
