The right place to introduce the separation is not in between TDT and TDT-prime, but in between TDT-prime's output and TDT-prime's decision. If its output is a strategy, rather than a number of boxes, then that strategy can include a byte-by-byte comparison; and if TDT and TDT-prime both do it that way, then they both win as much as possible.

But doesn't that make cliquebots, in general?

I'm thinking hard about this one...

Can all the TDT variants adopt a common strategy, but with different execution results, depending on source-code self-inspection and sim-inspection? Can that approach really work in general without creating CliqueBots? Don't know yet without detailed analysis.

Another issue is that Omega is not obliged to reveal the source-code of the sim; it could instead provide some information about the method used to generate / filter the sim code (e.g. a distribution the sim was drawn from) and still lead to a well-defined problem. Each TDT variant would not then know whether it was the sim.

I'm aiming for a follow-up article addressing this strategy (among others).

This sounds equivalent to asking "can a turing machine generate non-deterministically random numbers?" Unless you're thinking about coding TDT agents one at a time and setting some constant differently in each one.
