Vet a perf measurement (limiter, tuning, limits, errors, repeatability, relevance, and whether the work happened) before you report or act on it. Use when you run a benchmark or report a speedup or regression you measured. Use this when you produce a performance number: a PR's before and after, a regression claim, a hillclimb harness, or a library or config choice. Explain the Number says why. Answer each question below with evidence from a run, not from a guess about the code.
