 # Step 26: Abaqus B33 Reference Verification
 
-## 담당 역할과 필수 스킬
-
-- 담당 역할: `reference-verification-agent`
-- 필수 스킬: `fesa-reference-comparison`
-- `ARTIFACT CHECK -> COMPARE -> CLASSIFY -> REPORT` 순서를 지켜라.
+> 과거 개발 계획이다. 아래 작업·상태·예시는 현재 실행 지시가 아니다.
+> 현재 구현과 검증 한계는 [기능 요약](../../docs/linear-static-3d-euler-beam/README.md)을 따른다.
