I think the Requirements will work well. I was probably over-thinking; we have to remember that as long as we meet the underlying story point (Progress in this case -- the freedoms are progressively restricted) Dramatica will ensure everything works out.
As for the MC throughline and what her change is about, I think that will work itself out as we address that throughline -- again, the reason this whole Embroidery thing works is because we have a storyform backing us up.
Next story point...
First Story Driver (an Action): Lawanda discovers that the "powers that be" * know about a cryogenically frozen man who is believed to be both fertile and capable of surviving the revivification process. Aghast that they have been sitting on their hands about this, she is forced to befriend a doctor, Olivia. She never really liked Olivia but needs her help to revive the man (Clay).
* "Powers that be" is pretty vague, do we want to define the organization of this community yet? Is there a government, or rulers, or warlords, or ???
I originally was going to pick either Tam or Hawk as this doctor; @jassnip gave the idea of the Skeptic below.
(Note that "she is forced to befriend" is the decision/choice that the action forces. It's not something she would have done without the Action [discovery] forcing it.)
