New evidence in this case would be any dialogue or wording from a licensed work where the Doctor is explaining what makes a 'companion'. It's not what the companions think of themselves, it's what the Doctor thinks of them. Does the Doctor have a rulebook or a ticklist of sorts? That's the evidence that the Wiki's probably looking for.
