Bread doesn’t rot, it molds. Whether mold can grow depends on the conditions it’s kept in. The ingredients are availble to the public, the only preservative in the bun is calcium propionate which you’ll find in just about any other baked good on store shelves.
I bought a twin pack of Nutella from Costco. The unopened one developed mold after awhile, but the opened jar in the fridge was just fine. If anything, I was expecting at least the reverse.
That doesn’t explain the untarnished bun.

I never mentioned rot, I don’t think so anyway. Any bread I’ve ever had doesn’t look the same after 5 days.
