Thinking of we need to verify the k characters it got replaced by were zero? Tho I think the random computation should cover but but not sure

Core circuit looks good to me. Can you make it an argument in the main EmailVerifier component arguments and if on, then apply it to the body string? Also, have you tested it on real emails at all? I'm not convinced they all use \r.
