Busybox wc is back in every suite, for shits and giggles. checkwc now walks PATH and identifies each wc by its --version answer (coreutils and fastwc respond; busybox names itself in the error it prints), so a wc symlinked to fastwc is detected and skipped instead of silently racing us against ourselves, and a missing coreutils is a clear configure error. Every run now ends with the average speedup of fastwc against coreutils and busybox, computed from the per-case ratios. The fail-fast verdict now requires a measurable (>0ms) reference time, so sub-millisecond cases stop flaking on startup noise, and the 100M line monster is pinned back to the coreutils oracle instead of whatever oracle was raced last.
