Wondering how y’all would go about trimming the last SDL curve with the joined curve so that they’re a single closed polyline.

Not perfect yet, but close.
Must be enough to get to next stage. Good luck, Eef

Rethinking a bit, I found some better solutions, what closes the line up.
And changing input parameters gives some room.

… so that they’re a single closed polyline.

Assuming there is a closed region, one can use the CreateBooleanRegions method in a script:

I had to fiddle with your input parameters a bit to find a combination that didn’t have gaps (i.e. and would therefore fail to find a closed boolean region).
