 * `base` defaults to the commit this branch and origin/main share. The
 * tool fetches the history that commit needs when the checkout lacks it.
 * An explicit `base` is read as this checkout holds it, so run `git fetch
 * origin main` first for a current base. Drift is a report, not a gate —
 * the exit code is 0 whether or not the contracts moved. */
