OptionalrunThe live status, or the last run's.
running: a sync holds the corpus and keeps this status. idle: no lock — run
is the last run, if any. stale: the lock names a process on this host that is
gone. busy: another writer holds the corpus (ka reindex, doctor --fix), or
a sync on another host whose process cannot be checked from here.
The lock's holder, when there is a lock.
