To me, calling TDT “an extension of CDT” implies that it applies to a wider range of problems than CDT, while agreeing with CDT where CDT gives a well-defined answer.
But this is a correct characterization of what TDT does. It extends applicability of CDT from action-determined to decision-determined problems.

But CDT already gives well-defined answers to decision-determined problems such as Newcomb’s problem. They’re just not necessarily the right answers.
By “applies”, I mean “yields an output, which supporters claim is correct”, not “yields a correct output”.
