ADM.7:5.2 - The wrong test and an unavailable test
An archive requires an accepted person-identity result and a valid read grant. A device credential succeeds. That observation supports the device operation it actually checked; the handler cannot use it as the required person result or read grant.
If the person checker is unavailable, the outcome is unavailable checking. The existing approved alternative may supply a qualified person check through ADM.6. If the person check instead establishes that the person is different from the grant beneficiary, that is a substantive negative correspondence result, and the applicable service rule supplies the response.
These cases require different next actions despite each sometimes being displayed as “verification failed”.
