 ## [Unreleased]
 
 ### 변경
+- **디자인 시스템 SSOT 일괄 준수 (30파일)** — `frontend/design-system.html` 쇼케이스의 공통 컴포넌트와 `shared/constants/` 카탈로그를 우회하던 하드코딩 UI 를 전영역 치환. raw `<button>` → `<Button variant>` / raw `<input>` → `<Input>` / raw `<select>` → `<Select>` / 커스텀 탭 → `<TabBar>` + `<TabButton>` / raw checkbox → `<Checkbox>`. `text-red-400` 같은 다크 전용 색상을 `text-red-600 dark:text-red-400` 쌍으로 라이트 모드 대응. StatBox `color: string` prop 을 `intent: BadgeIntent` + `INTENT_TEXT_CLASS` 매핑으로 재설계. 에러 메시지도 `t('error.errorPrefix', { msg })` 로 통일. 영역: detection(6) / detection/components(4) / enforcement / surveillance(2) / admin(7) / parent-inference(3) / statistics / ai-operations(3) / dashboard / field-ops(2) / auth
 - **i18n 하드코딩 한글 제거 (alert/confirm/aria-label 우선순위)** — `common.json` 에 `aria` / `error` / `dialog` / `success` / `message` 네임스페이스 추가 (ko/en 대칭, 52개 키). 운영자 노출 `alert('실패: ' + msg)` 11건과 접근성 위반 `aria-label="역할 코드"` 등 40+건을 `t('aria.*')` / `t('error.*')` / `t('dialog.*')` 로 일괄 치환. parent-inference / admin / detection / enforcement / vessel / statistics / ai-operations 전 영역. MainLayout 언어 토글은 `title={t('message.switchToEnglish')}` + `aria-label={t('aria.languageToggle')}` 로 정비
 - **iran 백엔드 프록시 잔재 제거** — `IranBackendClient` dead class 삭제, `application.yml` 의 `iran-backend:` 블록 + `AppProperties.IranBackend` inner class 정리. prediction 이 kcgaidb 에 직접 write 하는 현 아키텍처에 맞춰 CLAUDE.md 시스템 구성 다이어그램 최신화. Frontend UI 라벨 `iran 백엔드 (분석)` → `AI 분석 엔진` 로 교체, system-flow manifest `external.iran_backend` 노드는 `status: deprecated` 마킹(노드 ID 안정성 원칙 준수, 1~2 릴리즈 후 삭제 예정)
 - **백엔드 계층 분리** — AlertController/MasterDataController/AdminStatsController 에서 repository·JdbcTemplate 직접 주입 패턴 제거. `AlertService` · `MasterDataService` · `AdminStatsService` 신규 계층 도입 + `@Transactional(readOnly=true)` 적용. 공통 `RestClientConfig @Configuration` 으로 `predictionRestClient` / `signalBatchRestClient` Bean 통합 → Proxy controller 들의 `@PostConstruct` ad-hoc 생성 제거
