I haven't been unable to find anything directly addressing something that came up in my game tonight. I played bounty on my friends card, and elected to not battle the one unit he attacked with. This sparked a discussion about the text on the card vs the text in the rule book.
The way I read it, you lose the enhancement if you lose an edge battle by 3 or more force icons. Since I didn't engage the attacking unit, I lost the edge battle automatically according to the rule book and not by force icons. Even if he decides to commit cards to the edge battle (usually something you would do to play fate cards that have beneficial effects) I'm not losing by force icons, I'm losing by default. The bounty enhancement doesn't get discarded.
I'm putting myself out there a bit... maybe I'm wrong, but it seemed pretty clear to me. I would love to get some insight from the community at large.
