The default differential run can select fewer covered sites than exist after a function is added or removed, forcing a manual --mutate-all rerun. Add mutate-file.sh (auto-reruns when Selected < Covered) and clean-builds.sh (removes worker-copy bloat), and document them plus the intrinsic upper-bound Gherkin survivors in the architect cheat-sheet. By specifier.
