This enumerated value gives the completion state of this specific queued task within the PSU's FSM workflow. This is a lower-level status than the parent stage's stageStatus, telling an admin whether this individual internal task unit -- one of possibly several driving a single stage forward -- has itself finished, which matters when a stage seems stuck despite some of its underlying tasks having completed. A typical value is a token such as completed once this task item has finished executing, or scheduled while it is still queued.
