Please describe the bug 🐞

1. We have a third-party service to clean up snapshot versions. During the cleaning process, if there is a long waiting time after the first confirmation of the lock's survival as shown;
2. During the waiting period, there were other normal submissions of batch 2026-02-08, and metadata_location was updated;
3. When the waiting for the third-party service ended, the metadata_location of batch 2026-02-08 was overwritten using the file of batch 2026-02-07 metadata_location.
4. This ultimately led to the data loss of batch 2026-02-08.
