 # Step 25: Build and Test Verification
 
-## 담당 역할과 필수 스킬
-
-- 담당 역할: `build-test-executor-agent`
-- 필수 스킬: `fesa-cpp-msvc-tdd`
-- 이 step은 검증과 보고만 수행한다. 실패를 production 변경으로 덮지 않는다.
+> 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.
