This is the final recorded pass/fail outcome for this specific historical FSM run of the deletion workflow. Unlike the live fsmStatus mirrored on the parent SwitchDelTask object, this is the fixed verdict for this one completed attempt, useful for auditing whether a specific past deletion attempt for this switch actually succeeded, even if a later retry, a separate FSM record, eventually did. A recorded 'FSM_FAIL_STS' here for an attempt from earlier today, alongside a newer successful attempt, tells you the deletion needed at least one retry before it actually removed the switch.
