After moving benchmark scripts to a tracked folder (paths turned into env vars), we ran one cold take per tool through the ported copy and checked three things. (1) Shape: the same per-take files and log keys as the old runs, listing any intentional differences (a file removed because its line moved into the main log, a new sampler file). (2) The tracked analysis scripts run unmodified on the new output. A partial run (1 take instead of 3) may need a tiny wrapper, because analysis loops expect takes 1..3; exec the script's functions, not its main loop. (3) Values fall inside the audited ranges from the old runs. One did not (a server RSS 7% above the audited range), and we reported it as-is rather than calling the port 'identical'. Label the run SMOKE, so nobody quotes it as a result. Commit any options added for the smoke run (e.g. TAKES=1) together with the port, and record the commit hash with the smoke result.
