So the contact tracers won't be using the phone/app IDs that the infected persons phone has logged? Or that is what the tracers will do if the individual the infected person mentions does not have the app. So the individuals phone is not linked to an App ID? For App users is the App ID linked to a phone number and stored on a central database. So when an App user is tested positive, his App record can be examined and all proximate users logged against the person tested positive are pulled up - they will each have an associated phone number that the tracers can use to contact all those proximate persons?
I think each phone will have a randomly generated code. Its the phone that is traced when some one notifies the NHS of potential covid19 symptoms. The tracers then try to notify the other phones that have been at the same time and location for a declared period of time. It is only then the phone's owner is identified and texted advice.
