Okay, then we have a logical link from C-platonic to D-platonic, and causal links descending from C-platonic to C-physical, E-platonic to E-physical, and D-platonic to D-physical to F-physical = D-physical xor E-physical. The idea being that when we counterfactualize on C-platonic, we update D-platonic and its descendents, but not E-platonic or its descendents.
I suppose that as written, this requires a rule, “for purposes of computing counterfactuals, keep in the causal graph rather than the logical knowledge base, any mathematical knowledge gained by observing a fact descended from your decision-output or any logical implications of your decision-output”. I could hope that this is a special case of something more elegant, but it would only be hope.
Ok. I think it would be very helpful to sketch, all in one place, what TDT2 (i.e., the envisioned avenue-2 version of TDT) looks like, taking care to pin down any needed sense of “dependency”. And similarly for TDT1, the avenue-1 version. (These suggestions may be premature, I realize.)
No, D was the Platonic simulator. That’s why the nature of the C->D dependency is crucial here.
