A device that has no issue list yet is not evaluated: it is out of every denominator and is not counted healthy. A device whose collector predates the on-device counters is out of the denominator of the DO-DIAG rows only, and what it did not collect is not collected, not a pass. “DoctorDO inference” marks a rule whose judgement, not only its fact, is DoctorDO's. Evidence and the fix are on each device's page.
