Juke is a title, above Captain, and referring to the Collective of Salamancers, the greater mission, and conveys respect for both. Therefore, introductions often include Juke Arcus, and Juke alone is a respectful form of address. Juke could be considered the physical manifestation of Salamancers as an ongoing mission.
Arcus is specifically the mech, its physical body and systems engineering. Most informal addresses and technical guides will use only "Arcus".
Juke Arcus as the full presentation uses they/them address pronouns, and the royal we as personal pronouns, mindful of the collective.
"We are Juke Arcus. Are you Friend or Food?"
Friends and Food are the only two categories for basically anything.
Friends are things which can communicate, especially sapient things, as well as plants, creatures, and technology that is non hostile and not intended to be consumed.
Food is.... a lot of things. Basically anything alive that isn't a Friend.
