## Remarks

- Requires a vault session and the vault right `change_metadata_structure`.
- When a task exists, the server queues the vault's pending tasks for running instead of
  waiting for its next scheduling round, on this server and, by broadcast, on the others.
- Use the returned ID as the starting point when waiting for background work (see the service
  overview).
