Served by the partial index on expires_at from the initial
migration, so the reaper no longer reads every lease to find the few
that expired.

Cheap liveness probe for the health endpoint. It must stay cheap: a
load balancer calls it constantly, against every replica, forever.

Best-effort cross-process mutual exclusion, so exactly one replica
runs a singleton background task. Granting unconditionally is correct
for a single-node or in-memory backend, which is why that is the
default. Read more
