This read-only INTEGER reports whether the test named in wvLastSelfTestType most recently passed(2) or failed(1). An admin monitoring this object gets a direct pass or fail health signal per hardware subsystem, letting them decide whether a terminal needs a service call before it is dispatched to a remote site. For example, wvLastSelfTestStatus reading failed(1) for the row where wvLastSelfTestType is ramTest would justify swapping the unit rather than trusting it in the field.
