When multiple instances concurrently recover the same orphan lock, both succeed because add() ignores insert()'s return value and insert() updates the timestamp unconditionally. Fix: - add() now checks insert()'s return value (0 = not acquired) - insert() uses conditional UPDATE (WHERE createdAt < ?) for orphan recovery so only one instance can claim an orphan lock
