When this script is used as the added unit-test proof, a regression or noisy environment where the parallel path is not faster only prints
❌ No significant difference; the process still exits 0 and the final summary still says all issues were verified. This makes the new proof unable to fail CI or manual validation in the exact scenario it is meant to catch; convert these checks to assertions or set a non-zero exit code on failure.Useful? React with 👍 / 👎.
