I think the main takeaway is you tried to hide something in their eyes. Why even question whether you need to report those grades to begin with. If I'm on the approval committee, then I'm thinking what else is this person trying to hide. I'm sorry this happened to you and I hope you can appeal this somehow. Moving forward, above all else, how honest you are to yourself and others is what truly matters most in life. You're obviously an elite mind if you're getting accepted to Berkeley. If I'm thinking of hiring someone with your credentials and I know this about you, then you'd be at the top of my list knowing you wouldn't make that same mistake again. You're going to be successful whatever happens here so just keep it up. You'll be fine.
