This value is a set of bit flags describing behavior attributes of this specific queued FSM task, such as whether it can be retried or run in parallel with others. It matters on a single queued work item that finite-state-machine must execute because these flags determine how UCS Manager is allowed to handle the task if it fails — for instance whether an automatic retry is even permitted for this particular task. A flags value on this workflow indicating a task is not retryable explains why a single failed task caused the whole workflow to fail outright rather than attempt again automatically.
