I don't know why it is so attractive to claim disagreement. In my 
message I already recognized that you probably want to run this edge. 
But it is an edge. 

I have further doubts: 
The UGE is stored in the browser, not in the backend. At the very moment 
of the interaction, you can't know whether your web wide UGE is still 
there. A user can have revoked your web wide exception by having erased 
your UGE in the browser store. If you have a site wide UGE, you have 
received a DNT:0 and the issue is moot. If you're just part of the 
auction, you don't have real estate on the target site to test the UGE 
because you're in the backend and you can't determine your UGE. 

You're mainly telling me: "We store a UGE into the Browser AND our 
backend and whatever the user does, we claim UGE because we have an UGE 
in our backend."

The absence of possible interaction is precisely the problem the 
transitory (or derived) permissions solve for the ad industry. I have 
the feeling that by over - optimizing you risk to break the model.

You can determine the freshness if you have contact with the UA. You 
can't assume the user hasn't changed anything only because you haven't 
seen it. This is not the model we have in section 6

Wait, you haven't obtained an UGE here. You simply can't know as you're 
part of the auction and not a part of the interaction. If you have your 
javascript already on the first party content site, you can check and 
leverage your UGE. In this case you have full permission, not a derived 
transitory permission. We are only talking about the latter here. And it 
doesn't affect the former.

I disagree that we disagree. I rather think we got lost in 
translation... But if you insist and the outcome is viable you can 
disagree with me and have me voted down... It is a detail, a pennon on a 
truck with "transitory permissions" written on both sides. Can we ship 
that truck first and then discuss the pennon?
