Quick questions: javelins with dueling style and natural weapon proficiency

What in the world is official standard?

Books and SAC according to AL, says TO. Nevermind that they called an AL Discord's channel as irrelevant but a reply on StackExchange somehow mattering (reply that said that both rulings are applicable and then deferred to JC).

Essentially if TO thinks they can use it to support their specific view then they'll treat it as acceptable... up until it is shown to support a counter argument or demonstrate an intended interpretation that goes against their very specific definition, in which case it would no longer be valid for any reason.
