I'm figuring that since Gaetanna spent days/weeks fiddling with the ships systems she would know that this "AI" isn't the ship's pre-installed AI, especially considering that Angel Industries would have made a detailed survey of the Gold Greed before they initially loaned it out to the group (and that she would theoretically have had access to that information (if Grandpa Vincent actually wanted to to learn something about business while on this voyage). Also, considering this ship is on a company funded expedition, there most likely would be a company policy in effect dealing with unwarranted/reported modifications which could negate any insurance claims or reimbursement that the crew may receive as compensation for them fixing any damage that may have resulted from ship on ship combat or general wear and tear.
