The logical relations for soundness is somewhat cumbersome. In Agda code, they are defined by recursion on the PER model, which obviously is not possible in our case. I think it might just be easier to copy the PER model and extends it. Then we prove two lemmas: one says that a PER model necessarily gives a gluing model, and the other one says that a gluing model can be degenerated to a PER model. Hopefully, this is enough to recover the recursive definitions in Agda. I am not sure how repetitive the lemmas will be. I hope not by a lot after prove these two lemmas. |
