This is the overall status of the FSM workflow tracked by this row (for example 'in progress', 'completed', or 'failed'). For this chassis slot endpoint, fsmStatus is the single field an admin polls to know whether this endpoint's current workflow is still running, finished cleanly, or needs attention, without having to inspect every individual stage row. A status of 'failed' here would send an admin down into the FsmStage and FsmTask rows for this same workflow to find exactly which step broke.
