NEUTRAL (no regression). On the OrderService god-class all baselines already name the SRP/DIP violations, split by genuine responsibility, and — notably — do not over-split into anemic classes. The skill neither helps nor harms at this difficulty; the feared dogmatic-over-split regression did not materialise. Follow-up: author a harder borderline scenario (a class that only looks multi-purpose) to find where the skill is load-bearing. Gate per skill-optimizer/release-gates.md.
