Yea, the paper discusses a probe with a mass between 50g and 500kg using a diamondoid data storage medium that holds ~6,250 exabytes per gram. Plenty of room for any blueprints you want to include, up to and including a planet full of humans. If not actually today’s tech, it is but a few years into the future. I’m sure my next computer will have a few hundred grams of that diamondoid storage.

Blueprints are the last of my concerns. What I think will be hard to do is to implement a full supply chain into a single space-travelling factory, including sourcing and refining of raw materials. But, regarding the blueprints, it now occurs to me that our "recipes" are made to work on our planet. Another one may lack some "ingredients" or have atmospheric conditions that could mess with the chemical reactions we use here. So we would need an advanced AI able to adapt production to the environment it finds.

Sourcing and refining materials are just blueprints. Adaptations for other environments are just different blueprints.

But honestly most of the work would be done in vacuum. Skip the planets, build the daughter probes out of asteroids. Most systems should have plenty of easily accessible material even if they don’t have a prominent asteroid belt, even if the probe has to scavenge the system’s oort cloud.
