# Expected Difference

| Axis | Skill Only | Skill + KDNA |
| --- | --- | --- |
| Diagnosis | Generic improvement checklist | Structural judgment failure |
| First fix | Stronger opening / concise wording | Create a contestable claim |
| Evidence | "Add examples" as generic advice | Evidence required to support the claim |
| Boundary | Treats post as copy-edit task | Avoids polishing before argument exists |

KDNA changes the review from execution advice to domain judgment.
