Quick answer
Prototype now has enough exact-intent support
The official wiki maintains a direct Prototype page, and the site already uses Prototype as a named support pick. That is enough public surface to promote Prototype into an exact local route without inventing ability numbers.
The practical answer is that Prototype fits players who want a support-leaning Survivor route with mobility utility and update-sensitive timing. Use this page for identity and routing, then move to ranking or tool pages for the next decision.
