This is a CucsFsmFlags bitmask of internal housekeeping flags UCS Manager sets on a queued workflow step in the extpol external-application registry's FSM. These bits are consumed by UCS Manager's own workflow engine to track internal bookkeeping for this queued registry task (such as whether it has already been dispatched); they aren't meant to be interpreted directly by an admin. In practice this value is mostly useful when compared across polls to confirm this queued registry task has actually been picked up for execution rather than left sitting untouched in the queue.
