Jason, How do you know "From Pam's point of view the event of her reaching Proxima Centauri happens *before *Sam's 4th birthday. But from Sam's point of view, Pam reaching Proxima Centauri happens *after *his 4th birthday!"? How do you measure that?

You have to be careful to eliminate SR time dilation effects which are MUTUAL illusions of measurement that disappear when relative motion ceases, and stick with only the actual time dilation (clock slowing) of GR effects of accelerations which are real and actual and are all that is left when the twins meet up again. It is only these GR acceleration effects which account for the different clock time t values when Pam and Sam meet up again. The SR time dilation effects vanish at that point since they are due only to relative linear velocities which then cease. What we do know is that both Pam's and Sam's clock time proceeds in an orderly sequential fashion through their own experience of the present moment, and that present moment is shared before and after the journey. Thus the same present moment was inhabited DURING the trip as well, but what each is doing at any particular present time moment is not necessarily knowable by the other.
