Is my carbon frame done? I have a carbon trek Emonda bicycle. Today, my rear derailleur got caught in my wheel. As a result, the rear derailleur is bent, the rear derailleur hanger snapped off, the chain got twisted and the right seat stay got scratched.
Is the scratch on my right seat stay too dangerous to ride again? It goes about 1-2 mm at the deepest part of the scratch.
I would not ride that frame as-is.
Whether it is repairable or not needs a hands-on inspection by a competent carbon fibre frame repairer in person.  So you need to strip everything else off the bike and send/take the bare frame to someone who can advise professionally.
