 # Step 21: Domain Mapper Modules
 
-## 담당 역할과 필수 스킬
-
-- 담당 역할: `implementation-agent`
-- 필수 스킬: `harness`, `fesa-cpp-msvc-tdd`
-- 이 Step만 `RED -> observed failure -> minimal GREEN -> focused/full VERIFY`로 수행한다.
+> 과거 개발 계획이다. 아래 작업·상태·예시는 현재 실행 지시가 아니다.
+> 현재 구현과 검증 한계는 [기능 요약](../../docs/cpp-object-oriented-modular-refactoring/README.md)을 따른다.
