Issue
A creator deletes unused records and expects every storage or listing metric to update instantly.
Cause
Deleting a key, deleting an entire store, and changing reported usage are different operations with different propagation behavior.
Fix
Use the supported deletion workflow for the correct target, keep a backup of anything important, and document the store name and scope. Do not emulate deletion by writing empty tables if the goal is to remove the key. Allow dashboard metrics time to refresh.
Verify
Attempt a read of the exact deleted key and confirm the expected not-found behavior before removing migration code.
