 ## 2026-07-30 - Add window.confirm for destructive actions
 **Learning:** Destructive actions like deleting groups and edge relationships previously occurred immediately without user confirmation.
 **Action:** Always wrap delete operations with window.confirm() dialogs and ensure corresponding tests successfully mock window.confirm.
+## 2024-08-16 - 파괴적 액션에 대한 사용자 확인 추가
+**Learning:** 테이블 편집 모달 내 '테이블 삭제'와 같은 파괴적인 액션이 사용자 확인 없이 즉시 실행되어, 의도치 않은 데이터 손실을 초래할 수 있었습니다.
+**Action:** 파괴적인 작업을 수행하는 버튼의 이벤트 핸들러에는 항상 `window.confirm`을 사용하여 사용자의 명시적인 확인을 받도록 개선했습니다.

 # Changelog
 
 ## Unreleased
+- [FE] 🛡️ **테이블 삭제 확인**: 테이블 편집 화면에서 삭제를 실행하기 전에 확인하여 실수로 인한 데이터 손실을 예방합니다.
 - [BE] 🔒 **Cryptography 50+ 보안 경계 갱신**: `pyproject.toml`과 두 hash-locked 요구사항 파일을 동일한 Cryptography 50+ 해석으로 정합화하여 PKCS#7 오류·타이밍 구분으로 인한 CVE-2026-69247 완화를 실제 설치·검증 경로에 반영했습니다.
 - [FE] ⚡ **검색 노드 참조 안정화 및 순차 스냅샷 폴링**: 같은 정규화 검색어와 원본 테이블 데이터에는 장식된 `node.data` 참조를 재사용하여 드래그 중 불필요한 하위 렌더링과 할당을 줄입니다. 스냅샷 폴링은 이전 요청이 끝난 뒤에만 다음 요청을 예약하며, 선택 변경·언마운트 후 도착한 오래된 성공 또는 실패 응답을 무시합니다.
 - [BE] 🔒 **공유 export 전 경로 redaction**: 공개 share의 SQL / index-design / reversing-spec export에서 코멘트·`example_value`를 제거합니다. 단위 테스트로 누출을 차단합니다.

 ## [Unreleased]
 ### Added
+- **테이블 삭제 확인**: 테이블 편집 화면에서 삭제하기 전에 확인창을 표시하여 실수로 인한 데이터 손실을 예방합니다.
 - **테이블 및 컬럼 편집 기능**: UI 패널을 통해 노드를 선택하고, 테이블의 이름/코멘트를 수정하며, 컬럼을 추가/수정/삭제하거나 테이블을 삭제할 수 있는 기능 추가.
 - **테스트 추가**: 프론트엔드 테스트 커버리지 100% 목표 달성을 위해 `cardinality.ts`, `types.ts`, `export.ts` 의 미달성 분기 및 함수 테스트 추가 (`cardinality_extra.test.ts` 등).
 - `.gitignore` 파일에 `coverage/` 폴더를 추가하여 불필요한 테스트 아티팩트가 커밋되지 않도록 보완.

 # Changelog
 
 ## Unreleased
-- [FE] 🛡️ **테이블 삭제 확인**: 테이블 편집 화면에서 삭제를 실행하기 전에 확인하여 실수로 인한 데이터 손실을 예방합니다.
 - [BE] 🔒 **Cryptography 50+ 보안 경계 갱신**: `pyproject.toml`과 두 hash-locked 요구사항 파일을 동일한 Cryptography 50+ 해석으로 정합화하여 PKCS#7 오류·타이밍 구분으로 인한 CVE-2026-69247 완화를 실제 설치·검증 경로에 반영했습니다.
 - [FE] ⚡ **검색 노드 참조 안정화 및 순차 스냅샷 폴링**: 같은 정규화 검색어와 원본 테이블 데이터에는 장식된 `node.data` 참조를 재사용하여 드래그 중 불필요한 하위 렌더링과 할당을 줄입니다. 스냅샷 폴링은 이전 요청이 끝난 뒤에만 다음 요청을 예약하며, 선택 변경·언마운트 후 도착한 오래된 성공 또는 실패 응답을 무시합니다.
 - [BE] 🔒 **공유 export 전 경로 redaction**: 공개 share의 SQL / index-design / reversing-spec export에서 코멘트·`example_value`를 제거합니다. 단위 테스트로 누출을 차단합니다.

 # Changelog
 
 ## Unreleased
+- [FE] 🛡️ **테이블 삭제 확인**: 테이블 편집 화면에서 삭제를 실행하기 전에 확인하여 실수로 인한 데이터 손실을 예방합니다.
 - [BE] 🔒 **Cryptography 50+ 보안 경계 갱신**: `pyproject.toml`과 두 hash-locked 요구사항 파일을 동일한 Cryptography 50+ 해석으로 정합화하여 PKCS#7 오류·타이밍 구분으로 인한 CVE-2026-69247 완화를 실제 설치·검증 경로에 반영했습니다.
 - [FE] ⚡ **검색 노드 참조 안정화 및 순차 스냅샷 폴링**: 같은 정규화 검색어와 원본 테이블 데이터에는 장식된 `node.data` 참조를 재사용하여 드래그 중 불필요한 하위 렌더링과 할당을 줄입니다. 스냅샷 폴링은 이전 요청이 끝난 뒤에만 다음 요청을 예약하며, 선택 변경·언마운트 후 도착한 오래된 성공 또는 실패 응답을 무시합니다.
 - [BE] 🔒 **공유 export 전 경로 redaction**: 공개 share의 SQL / index-design / reversing-spec export에서 코멘트·`example_value`를 제거합니다. 단위 테스트로 누출을 차단합니다.

 ## [Unreleased]
 ### Added
+- **테이블 삭제 확인**: 테이블 편집 화면에서 삭제하기 전에 확인창을 표시하여 실수로 인한 데이터 손실을 예방합니다.
 - **테이블 및 컬럼 편집 기능**: UI 패널을 통해 노드를 선택하고, 테이블의 이름/코멘트를 수정하며, 컬럼을 추가/수정/삭제하거나 테이블을 삭제할 수 있는 기능 추가.
 - **테스트 추가**: 프론트엔드 테스트 커버리지 100% 목표 달성을 위해 `cardinality.ts`, `types.ts`, `export.ts` 의 미달성 분기 및 함수 테스트 추가 (`cardinality_extra.test.ts` 등).
 - `.gitignore` 파일에 `coverage/` 폴더를 추가하여 불필요한 테스트 아티팩트가 커밋되지 않도록 보완.
