This is the plain-text name of the current overall FSM status for this Downloader job -- essentially the headline state such as in-progress, completed, or failed. This is the single field most admins would check first to know at a glance whether a specific firmware download is done, still running, or needs attention, without digging into the more granular stage and progress fields. A status of 'downloadFailed' next to a fileName of ucs-6454-k9-bundle.bin tells an admin immediately which specific download job needs to be retried.
