This paper talks about reflexive decision models and claims to develop a form of CDT which one boxes.

It's in my to-read list but I haven't got to it yet so I'm not sure whether it's of interest but I'm posting it just in case (it could be a while until I have time to read it so I won't be able to post a more informed comment any time soon).

Though this theory post-dates TDT and so isn't interesting from that perspective.
