The change upset what I thought I understood for 2+ years...about the nature of this protocol, based on the previous query design. I had been basing assurance on properties you advocated as critical to the security logic, previously: inverse functional relations - that are now no longer present or dominate the security enforcement logic. It will take some time to settle down, as I understand the change.

Oops that's not true. There are semantic changes, we used to have

key ------identity------> agent

Now we have

agent ------key-----> key

And then there are some other changes of that nature. They don't change the security characteristics, that is what I meant, 
since you they imply each other. Ie: where the one is true, the other is true too.
