Buying an Aeumifesh in play?

Let’s say for argument’s sake a Vaylen didn’t buy the Aeumifesh trait at burning, what would the Resources Ob be? I’m thinking something like this:

Aeumifesh Tt 6pts
An aeumifesh. See the Aeumifesh trait for description.
Technological traits: Enhancement (allows test), Categorical Limitation x2 (May only operate machines, and may only be used by a Naiven)

You can get it either with Tech or via the ALF. Both are acceptable ways to generate biomechanical tech!
