Sorry for the delay! After some discussion, we've decided that Vielot is an acceptable patron choice as long as it doesn't confer any additional benefit to the weapon! So as you said, no stat buffs and no Legend Lore, etc. Vielot's ability to aid Clear with certain tasks will also be somewhat limited by the will of the dice and mod availability, but we're very excited to see what you do with her.

Additionally, as a seeker of knowledge, Vielot would be classified as a Star/Seeker patron. So Clear's Otherworldly Patron benefit would be the spell Locate Object!
