+# VD-01: TypeScript 7과 ESLint 10의 점진적 전환 도구
+
+- 상태: Accepted
+- 결정일: 2026-07-26
+- 적용 브랜치: `feature-frontend-typescript-tooling-foundation`
+
+## 배경
+
+저장소는 TypeScript `7.0.2`와 ESLint `10.8.0`을 고정하고 있다. 첫 전환
+브랜치는 compiler를 변경하거나 production source를 일괄 변환하지 않고
+JS/JSX/TS/TSX가 같은 품질 게이트를 통과하게 해야 한다.
+
+결정 시점의 package peer contract는 다음과 같다.
+
+- `typescript-eslint@8.65.0`과 canary는 TypeScript `<6.1.0`을 요구한다.
+- `eslint-plugin-jsx-a11y@6.10.2`는 ESLint `<=9`를 요구한다.
+- `eslint-plugin-react-hooks@7.1.1`은 ESLint 10을 지원한다.
+- Babel 8 ESLint parser는 ESLint 10을 지원하고 Node `>=24.11.0`을 요구한다.
+
+호환되지 않는 peer dependency를 강제 설치하면 lockfile 검증은 통과하더라도
+지원되지 않는 parser와 rule 조합을 플랫폼 계약으로 만들게 된다.
+
+## 결정
+
+1. TypeScript `7.0.2`와 ESLint `10.8.0`을 유지한다.
+2. TypeScript/TSX의 ESLint syntax parsing에는
+   `@babel/eslint-parser`와 TypeScript/JSX syntax plugin을 사용한다.
+3. TypeScript의 이름 해석, unused 진단과 type semantics는 `tsc`가 소유한다.
+   Babel parser가 TypeScript scope manager를 제공하지 않으므로 TS 파일의
+   core `no-undef`와 `no-unused-vars`는 끄고 분리된 app/node/test TypeScript
+   project를 필수 게이트로 실행한다.
+4. React Hook 규칙은 호환되는 `eslint-plugin-react-hooks`로 즉시 적용한다.
+5. JSX 접근성은 현재의 semantic component contract, Testing Library,
+   axe 기반 cross-browser gate와 수동 검토 계약이 계속 담당한다. 호환되지 않는
+   `eslint-plugin-jsx-a11y`는 설치하지 않는다.
+6. Babel 8의 지원 범위에 맞춰 Node engine 하한을 `24.11.0`으로 명시한다.
+7. production source의 대량 rename은 이 결정에 포함하지 않는다.
+
+## 검증
+
+- `check:types`는 app, Node scripts/config, tests project를 모두 검사한다.
+- JS invalid-call, TS invalid port, TS discriminated-union fixture는 실패해야 한다.
+- ESLint와 dependency-cruiser는 TS/TSX architecture fixture를 검사한다.
+- registry scanner는 TS registry의 required field, uniqueness와 reference를
+  검증한다.
+- browser security gate는 TSX의 금지된 raw HTML fixture를 거절한다.
+
+## 후속 검토와 제거
+
+`typescript-eslint`가 TypeScript 7을, JSX 접근성 plugin이 ESLint 10을 공식
+지원하면 별도 dependency 브랜치에서 peer metadata와 전체 negative fixture를
+재검증한다. 교체할 때는 Babel parser package와 TS 전용 ESLint override를
+함께 제거한다. compiler downgrade나 `--force` 설치는 이 ADR의 rollback
+방법이 아니다.
