Are there any official rulings on Sash of the War Champion?

I have found several discussions, but no official ruling on how Sash of the War Champion works with no fighter levels.

Sash of the War Champion wrote:

The wearer treats his Fighter level as 4 higher than normal for the purpose of the Armor Training and Bravery class features.

There are 2 basic questions:

1. If a character with no fighter levels wears this, do they gain the Armor Training and Bravery class features?

2. If a character with 1 fighter level wears this, do they gain the Armor Training and Bravery class features?

Bonus question:

Does Sash of the War Champion stack with Band of the Stalwart Warrior to give +8 effective Fighter levels for the Bravery class feature?

In general, "don't have" is considered different than "have zero", and you aren't allowed to treat "don't have X" as "have zero X" for the purpose of adding. So no to 1, and... probably to 2?

I don't know of any specific official rulings on it, nor where to find the general ruling.

1. Not sure, but I would guess not since it doesn't have wording to suggest non-Fighters can be treated as Fighters.

2. Hero Lab tells me yes on my Cleric/Fighter, but that isn't official support. I believe there is a faq about getting things before you actually have them, but I forget where.

Bonus: I don't believe so, as they both apply to your Fighter level, not to each other. So you are effectively increasing your Fighter level by 4 from two different sources, and since they aren't bonuses they don't stack.
