     * `pending_cleanup` lease exists, so this lock serializes the two writes:
     *
     * - The environment still exists: the insert records the orphan with the
     *   environment reference. A concurrent delete blocks on the lock, then its
     *   `not exists (pending_cleanup)` predicate fails, so the delete refuses.
     * - The environment is already gone (a delete won the race before this
     *   insert): the insert records the orphan with a null environment
     *   reference. The row carries the immutable provider metadata the sweep
     *   needs, so the teardown still runs. This closes the window the finding
     *   describes, where the foreign-key insert fails after a delete.
