      # above stops at the root workspace members and never reaches it. Its
      # tests run in this job rather than in `test` because clippy has already
      # compiled the test targets, and because they need none of that job's
      # leanSpec fixtures.
      # `--locked` so the committed Cargo.lock is actually enforced: without it
      # cargo silently resolves and rewrites the lockfile in CI, and a stale or
      # missing entry never fails the build.
