The Concluding Event or Final Story Driver in Star Wars is when the Death Star goes Ka-blooie. The Story Drivers in Dramatica are tied to the Overall Story Throughline and when the inequity in that Throughline is resolved (or unresolved as the case may be)--not when the presentation of the narrative ends.
My outline above was to show how you would break up individual Signposts into individual sequences, not an exact outline that should be followed to the letter.
Many stories end their Overall Story Throughlines and then carry out their fulfillment of the conclusion of Main Character, Influence Character, and Relationship Story Throughlines.
The Shawshank Redemption is a great example of this. The Concluding Event of that Throughline is when the Warden blows his head off. Then you have a whole bunch of Main Character stuff, then a smidge of Influence Character, and then finally you wrap up with Relationship Story Throughline.
