The first point is made in paragraph #1:

"Timeless decision theory (TDT) is an extension of causal decision networks that compactly represents uncertainty about correlated computational processes and represents the decision-maker as such a process."

Warning: my comment here is based on dim memories and vague understandings. That said...

Are you sure that being an extension of causal decision networks is the same as being an extension of causal decision theory? I took "causal decision networks" to be referring to the Judea Pearl-inspired stuff. I thought that Eliezer said somewhere that CDT just assumes causal dependencies wherever it wants, while Eliezer derives them with causal networks.
