Enum Liveness 

pub enum Liveness {
    Alive,
    Stale,
}

Outcome of probing whether a recorded lock owner is still alive.

Kept as a distinct type (rather than a bare bool) so callers can treat Unknown conservatively — an unprobeable owner is not silently reclaimed.

Variants

Alive

The recorded owner is alive and its start token matches: the lock is held.

Stale

The recorded owner is gone (pid dead) or was replaced (pid reused): the lock is stale and may be reclaimed.
