@jkeskingvillage after the first selection on the Toy Domain, the returned plan is missing an edge (the choice infos seem to be correct)

Let me investigate this.

Also, Build Backwards seems more of an issue:

Toy Domain

It does stop at the first fork but IMO the graph needs to show the fork as well otherwise the user cannot pick.

Travel Domain

The whole graph shows up.

@jkeskingvillage I have added an extra node for build backward so that the graph does not have multiple roots

Now to the question of what the graph should look like

Toy Domain

For Toy Domain we get this 👇 which I think (?) is correct, except that I am highlighting in the same direction as others (forward) so the highlight is wrong. On the other hand, I don't think highlighting backward help coz here the buffer edge is not actually a choice. In general, the fork leading up from the first forking node will have some non-choices, which I supposed is a disadvantage for the BUILD mode. So nothing much to do here (I will change the highlight to the forking node only).

Travel Domain

This one does not look correct. The graph goes all the way back to the first confluence of all edges -- which I suppose is correct. However, the highlight is on the wrong node in the middle of the first fork. This is because I am taking the first among the available_for_choice marked True (as we do in the Selection View). What's the desired action here?

[jkeskingvillage]

I can sort the choice by their distance from the initial state. I will put the one with the closest to the initial condition to the first position in ChoiceInfos.
