This reports essentially the same operability assessment for the fan module as a distinct property, per its operability field. As with the individual fan's fields, a mismatch between operState and operability for this module is worth an admin's attention as a possible transitional fault state rather than a clean pass/fail. An operability of 'degraded' while operState still reads 'operable' for this module flags it as one to monitor before it potentially worsens.
