Great idea. Cool mission, and will love to play it.
Quite an interesting concept to reward both going for mutations and abstaining from mutations in the scoring mechanic. It seemed contradictory at first glance, but after some consideration, it could encourage some interesting decision making.
Does need a clarity edit and some clean up, e.g. "for each uncontested growth node" can be interpreted as no one controlling the node.
Overall, this looks like a fun mission.
