> The {{OnCompletionAction}} currently only receives the {{JobResult}} when the job terminates.
For further archiving of the {{ArchivedExecutionGraph}}, we should change this to {{AccessExecutionGraph}}.
The {{AccessExecutionGraph}} contains all the information to derive the {{JobResult}} and
additionally the information needed for serving information about completed jobs.
