Rejected EA from MIT. I'm shocked and don't know what went wrong.

I was outright rejected EA as a domestic student. I'm truly baffled - I thought I would at least be deferred. I'm really thought that I would be competitive. I don't understand what went wrong. There must be some kind of bright red flag in my application that my school college counselor and external college counselor didn't catch?? Maybe I bombed the interview??? I truly have no idea.

Stats:

White, male, very high income, California, ultra-competitive Bay Area public cchool

1590 SAT (790 Math, 800 EBRW)

3.86 UW, 4.41 W. I had a 3.5 GPA in sophomore year due to undiagnosed severe ADHD. Since then, I have been properly medicated. I have otherwise gotten all A's (except for an A- in Phys C) since.

13 AP's. The standard stuff, Calc AB, BC, Phys C, etc. Scored 5 on every exam.

Class Rank: 17/401

  • I have taken 13 dual enrollment math classes at a local community college and a local private college, all the way up to a few senior-level classes (Mathematical Statistics and Operations Research 1).
  • I did research under a math professor at a T50 for 3 summers. I was on a published paper as third author and another published paper as second author. I made meaningful contributions to the research process. In one of the papers, I suggested the 'key idea' that led to the breakthrough, so to speak, in the proof.
  • President of my school's math club.
  • Member of my school's math team for 4 years. (the team is not the same as the club)

LOR's:

  • The math professor I worked under wrote me a glowing letter of recommendation. He was very impressed by me and that my mathematical ability and maturity was better than many of his graduate students. (11/10 letter)
  • Math club advisor wrote me a LOR. She taught me in Calc BC and clearly liked me as she chose me to be president of the math club over 11 other applicants.
  • AP Lit teacher. She did not know me well but I got an A in the class.

My interview went well. My alumni interviewer went to my high school in the 90's and majored in math at MIT, and we related very well. We spent the entire time talking about math, it was a really fun conversation. After the interview, he said that I was clearly very smart and that MIT would be lucky to have me. I'm not sure if these were just pleasantries, but I'm pretty sure that he liked me a lot.

I'm just shocked. I can understand being deferred, MIT is competitive, after all. But being a domestic student, and being rejected EA??? I just don't get it. Rejected!

I was originally going to apply to Princeton single-choice EA, but I visited both Princeton and MIT and talking with the students at both schools and decided to apply to MIT and not Princeton. I connected with the MIT students on a deeper level, in a way that I hadn't connected with the Princeton students. I talk to one of the MIT students that I met during my visit on Discord nearly every day. He's one of my best friends and I was looking so forward to joining him at MIT.

I'm just devastated. I'm just devastated. I don't know what more I could have possibly done. Should I have invested my time into competitive math and won an IMO medal instead of taking dual enrollment classes??? I just don't understand.
