pub fn default_classify(
sui: &CapturedOutput,
nix: &CapturedOutput,
compare_ok: impl FnOnce(&CapturedOutput, &CapturedOutput) -> bool,
) -> VerdictExpand description
Shared verdict skeleton — handles spawn failure, timeout, and the

compare_ok closure, which is only called when both engines exit 0.
