+⚠️ 중요: 모든 품목기준관리 기능을 그대로 가져와야 함
+⚠️ 중요: 수정 절차 간단화가 핵심 (3방향 동기화 → 1곳 수정)
+⚠️ 중요: 모든 기능이 정확히 동일하게 작동해야 함

+| 3 | **기존 페이지 반영** | 테스트 페이지에서 수정 → 기존 품목기준관리 페이지에 반영 |
+| 4 | **품목관리 반영** | 테스트 페이지에서 수정 → 품목관리 동적 폼에 반영 |

+기존 페이지 (Context) ────┘
+
+→ 상태 관리 방식만 다르고, API/DB는 공유
+→ 테스트 페이지에서 수정한 내용이 품목관리 페이지에 그대로 적용되어야 함
+→ 이것이 성공하면 Zustand 리팩토링이 완전히 검증된 것

+
+## 1. 현재 문제점 분석
+
+### 1.1 중복 상태 관리 (3방향 동기화)
+
+현재 `ItemMasterContext.tsx`에서 섹션 수정 시:
+
+```typescript
+// updateSection() 함수 내부 (Line 1464-1486)
+setItemPages(...)           // 1. 계층구조 탭
+setSectionTemplates(...)    // 2. 섹션 탭
+setIndependentSections(...) // 3. 독립 섹션
+```
+
+**문제점**:
+- 같은 데이터를 3곳에서 중복 관리
+- 한 곳 업데이트 누락 시 데이터 불일치
+- 모든 CRUD 함수에 동일 패턴 반복
+- 새 기능 추가 시 3곳 모두 수정 필요
+
+### 1.2 현재 상태 변수 목록 (16개)
+
+| # | 상태 변수 | 설명 | 중복 여부 |
+|---|----------|------|----------|
+| 1 | `itemMasters` | 품목 마스터 | - |
+| 2 | `specificationMasters` | 규격 마스터 | - |
+| 3 | `materialItemNames` | 자재 품목명 | - |
+| 4 | `itemCategories` | 품목 분류 | - |
+| 5 | `itemUnits` | 단위 | - |
+| 6 | `itemMaterials` | 재질 | - |
+| 7 | `surfaceTreatments` | 표면처리 | - |
+| 8 | `partTypeOptions` | 부품유형 옵션 | - |
+| 9 | `partUsageOptions` | 부품용도 옵션 | - |
+| 10 | `guideRailOptions` | 가이드레일 옵션 | - |
+| 11 | `sectionTemplates` | 섹션 템플릿 | ⚠️ 중복 |
+| 12 | `itemMasterFields` | 필드 마스터 | ⚠️ 중복 |
+| 13 | `itemPages` | 페이지 (섹션/필드 포함) | ⚠️ 중복 |
+| 14 | `independentSections` | 독립 섹션 | ⚠️ 중복 |
+| 15 | `independentFields` | 독립 필드 | ⚠️ 중복 |
+| 16 | `independentBomItems` | 독립 BOM | ⚠️ 중복 |
+
+**중복 문제가 있는 엔티티**:
+- **섹션**: `sectionTemplates`, `itemPages.sections`, `independentSections`
+- **필드**: `itemMasterFields`, `itemPages.sections.fields`, `independentFields`
+- **BOM**: `itemPages.sections.bom_items`, `independentBomItems`
+

+
+## 2. 리팩토링 설계
+
+### 2.1 정규화된 상태 구조 (Normalized State)
+
+```typescript
+// stores/useItemMasterStore.ts
+interface ItemMasterState {
+  // ===== 정규화된 엔티티 (ID 기반 딕셔너리) =====
+  entities: {
+    pages: Record<number, PageEntity>;
+    sections: Record<number, SectionEntity>;
+    fields: Record<number, FieldEntity>;
+    bomItems: Record<number, BOMItemEntity>;
+  };
+
+  // ===== ID 목록 (순서 관리) =====
+  ids: {
+    pages: number[];
+    independentSections: number[];  // page_id가 null인 섹션
+    independentFields: number[];    // section_id가 null인 필드
+    independentBomItems: number[];  // section_id가 null인 BOM
+  };
+
+  // ===== 참조 데이터 (중복 없음) =====
+  references: {
+    itemMasters: ItemMaster[];
+    specificationMasters: SpecificationMaster[];
+    materialItemNames: MaterialItemName[];
+    itemCategories: ItemCategory[];
+    itemUnits: ItemUnit[];
+    itemMaterials: ItemMaterial[];
+    surfaceTreatments: SurfaceTreatment[];
+    partTypeOptions: PartTypeOption[];
+    partUsageOptions: PartUsageOption[];
+    guideRailOptions: GuideRailOption[];
+  };
+
+  // ===== UI 상태 =====
+  ui: {
+    isLoading: boolean;
+    error: string | null;
+    selectedPageId: number | null;
+    selectedSectionId: number | null;
+  };
+}
+```
+
+### 2.2 엔티티 구조
+
+```typescript
+// 페이지 엔티티 (섹션 ID만 참조)
+interface PageEntity {
+  id: number;
+  page_name: string;
+  item_type: string;
+  description?: string;
+  order_no: number;
+  is_active: boolean;
+  sectionIds: number[];  // 섹션 객체 대신 ID만 저장
+  created_at?: string;
+  updated_at?: string;
+}
+
+// 섹션 엔티티 (필드/BOM ID만 참조)
+interface SectionEntity {
+  id: number;
+  title: string;
+  page_id: number | null;  // null이면 독립 섹션
+  order_no: number;
+  is_collapsible: boolean;
+  default_open: boolean;
+  fieldIds: number[];      // 필드 ID 목록
+  bomItemIds: number[];    // BOM ID 목록
+  created_at?: string;
+  updated_at?: string;
+}
+
+// 필드 엔티티
+interface FieldEntity {
+  id: number;
+  field_key: string;
+  field_name: string;
+  field_type: string;
+  section_id: number | null;  // null이면 독립 필드
+  order_no: number;
+  is_required: boolean;
+  options?: any;
+  default_value?: any;
+  created_at?: string;
+  updated_at?: string;
+}
+
+// BOM 엔티티
+interface BOMItemEntity {
+  id: number;
+  section_id: number | null;  // null이면 독립 BOM
+  child_item_code: string;
+  child_item_name: string;
+  quantity: number;
+  unit: string;
+  order_no: number;
+  created_at?: string;
+  updated_at?: string;
+}
+```
+
+### 2.3 수정 절차 비교
+
+#### Before (현재): 3방향 동기화
+
+```typescript
+const updateSection = async (sectionId, updates) => {
+  const response = await api.update(sectionId, updates);
+
+  // 1. itemPages 업데이트
+  setItemPages(prev => prev.map(page => ({
+    ...page,
+    sections: page.sections.map(s => s.id === sectionId ? {...s, ...updates} : s)
+  })));
+
+  // 2. sectionTemplates 업데이트
+  setSectionTemplates(prev => prev.map(t =>
+    t.id === sectionId ? {...t, ...updates} : t
+  ));
+
+  // 3. independentSections 업데이트
+  setIndependentSections(prev => prev.map(s =>
+    s.id === sectionId ? {...s, ...updates} : s
+  ));
+};
+```
+
+#### After (Zustand): 1곳만 수정
+
+```typescript
+const updateSection = async (sectionId, updates) => {
+  const response = await api.update(sectionId, updates);
+
+  // 딱 1곳만 수정하면 끝!
+  set((state) => ({
+    entities: {
+      ...state.entities,
+      sections: {
+        ...state.entities.sections,
+        [sectionId]: { ...state.entities.sections[sectionId], ...updates }
+      }
+    }
+  }));
+};
+```
+
+### 2.4 파생 상태 (Selectors)
+
+```typescript
+// 계층구조 탭용: 페이지 + 섹션 + 필드 조합
+const usePageWithDetails = (pageId: number) => {
+  return useItemMasterStore((state) => {
+    const page = state.entities.pages[pageId];
+    if (!page) return null;
+
+    return {
+      ...page,
+      sections: page.sectionIds.map(sId => {
+        const section = state.entities.sections[sId];
+        return {
+          ...section,
+          fields: section.fieldIds.map(fId => state.entities.fields[fId]),
+          bom_items: section.bomItemIds.map(bId => state.entities.bomItems[bId]),
+        };
+      }),
+    };
+  });
+};
+
+// 섹션 탭용: 모든 섹션 (페이지 연결 여부 무관)
+const useAllSections = () => {
+  return useItemMasterStore((state) =>
+    Object.values(state.entities.sections)
+  );
+};
+
+// 독립 섹션만
+const useIndependentSections = () => {
+  return useItemMasterStore((state) =>
+    state.ids.independentSections.map(id => state.entities.sections[id])
+  );
+};
+```

+## 6. 테스트 시나리오
+
+### 6.1 섹션 수정 동기화 테스트
+
+```
+시나리오: 섹션 이름 수정
+1. 계층구조 탭에서 섹션 선택
+2. 섹션 이름 "기본정보" → "기본 정보" 수정
+3. 검증:
+   - [ ] 계층구조 탭에 반영
+   - [ ] 섹션 탭에 반영
+   - [ ] 독립 섹션(연결 해제 시) 반영
+   - [ ] API 호출 1회만 발생
+```
+
+### 6.2 필드 이동 테스트
+
+```
+시나리오: 필드를 다른 섹션으로 이동
+1. 섹션 A에서 필드 선택
+2. 섹션 B로 이동 (unlink → link)
+3. 검증:
+   - [ ] 섹션 A에서 필드 제거
+   - [ ] 섹션 B에 필드 추가
+   - [ ] 계층구조 탭 반영
+   - [ ] 필드 탭에서 section_id 변경
+```
+
+### 6.3 독립 → 연결 테스트
+
+```
+시나리오: 독립 섹션을 페이지에 연결
+1. 독립 섹션 선택
+2. 페이지에 연결 (linkSectionToPage)
+3. 검증:
+   - [ ] 독립 섹션 목록에서 제거
+   - [ ] 페이지의 섹션 목록에 추가
+   - [ ] 섹션 탭에서 page_id 변경
+```
+
+---
+
+## 7. 롤백 계획
+
+문제 발생 시:
+1. 테스트 페이지 라우트 제거
+2. 스토어 코드 삭제
+3. 기존 `ItemMasterContext` 그대로 사용
+
+**리스크 최소화**:
+- 기존 코드 수정 없음
+- 새 코드만 추가
+- 언제든 롤백 가능
+
+---
+
+## 8. 성공 기준
+
+| 항목 | 기준 |
+|-----|------|
+| **기능 동등성** | 기존 모든 기능 100% 동작 |

+# 품목기준관리 Zustand 리팩토링 - 세션 컨텍스트
+
+> 다음 세션에서 이 문서를 먼저 읽고 작업 이어가기
+
+## 🎯 프로젝트 목표
+
+**핵심 목표:**
+1. 품목기준관리 100% 동일 기능 구현
+2. **더 유연한 데이터 관리** (Zustand 정규화 구조)
+3. **개선된 UX** (Context 3방향 동기화 → Zustand 1곳 수정)
+
+**접근 방식:**
+- 기존 컴포넌트 재사용 ❌
+- 테스트 페이지에서 완전히 새로 구현 ✅
+- 분리된 상태 유지 → 복구 시나리오 보장
+
+---
+
+## 세션 요약 (2025-12-21 - 10차 세션)
+
+### ✅ 오늘 완료된 작업
+
+1. **기존 품목기준관리와 기능 비교 분석**
+   - 기존 페이지의 모든 핵심 기능 구현 확인
+   - 커스텀 탭 관리는 기존 페이지에서도 비활성화(주석 처리)됨
+   - 탭 관리 기능은 로컬 상태만 사용 (백엔드 미연동, 새로고침 시 초기화)
+
+2. **Phase D-2 (커스텀 탭 관리) 분석 결과**
+   - 기존 페이지의 "탭 관리" 버튼: 주석 처리됨 (미사용)
+   - 속성 하위 탭 관리: 로컬 상태로만 동작 (영속성 없음)
+   - **결론**: 선택적 기능으로 분류, 핵심 기능 구현 완료
+
+---

+- [x] 브랜치 상태 확인 (`feature/item-master-zustand`)
+- [x] 기존 작업 혼동 정리 (품목관리 CRUD vs 품목기준관리 설정)
+- [x] 작업 대상 파일 확인 (`ItemMasterDataManagement.tsx` - 1,799줄)
+- [x] 기존 훅 분리 상태 파악 (7개 훅 이미 존재)
+- [x] `ItemMasterDataManagement.tsx` 상세 분석 완료
+- [x] 훅 분리 계획서 작성 (`[PLAN-2025-12-24] hook-extraction-plan.md`)
+- [x] **Phase 1: 신규 훅 4개 생성**
+  - `useInitialDataLoading.ts` - 초기 데이터 로딩 (~130줄)
+  - `useImportManagement.ts` - 섹션/필드 Import (~100줄)
+  - `useReorderManagement.ts` - 드래그앤드롭 순서 변경 (~80줄)
+  - `useDeleteManagement.ts` - 삭제/언링크 핸들러 (~100줄)
+- [x] **Phase 2: UI 컴포넌트 2개 생성**
+  - `AttributeTabContent.tsx` - 속성 탭 콘텐츠 (~340줄)
+  - `ItemMasterDialogs.tsx` - 다이얼로그 통합 (~540줄)
+- [x] 빌드 테스트 통과
+
+### 현재 상태
+- **메인 컴포넌트**: 1,799줄 → ~1,478줄 (약 320줄 감소)
+- **신규 훅**: 4개 생성 및 통합
+- **신규 UI 컴포넌트**: 2개 생성 (향후 추가 통합 가능)
+- **빌드**: 통과
+
+### 다음 TODO (커밋 후)
+1. Git 커밋 (Phase 1, 2 변경사항)
+2. Phase 3: 추가 코드 정리 (선택적)
+   - 속성 탭 내용을 `AttributeTabContent`로 완전 대체 (추가 ~500줄 감소 가능)

+
+## 분리 계획
+
+### Phase 1: 신규 훅 생성 (4개)
+
+#### 1. `useInitialDataLoading` (~100줄 분리)
+
+**분리 대상:**
+- 초기 데이터 로딩 useEffect (387-492줄)
+- 로딩/에러 상태 (isInitialLoading, error)
+- transformers 호출 로직
+
+**반환값:**
+```typescript
+{
+  isInitialLoading: boolean;
+  error: string | null;
+  reload: () => Promise<void>;
+}
+```
+
+#### 2. `useImportManagement` (~80줄 분리)
+
+**분리 대상:**
+- Import 다이얼로그 상태 (512-516줄)
+- handleImportSection (519-530줄)
+- handleImportField (540-559줄)
+- handleCloneSection (562-570줄)
+
+**반환값:**
+```typescript
+{
+  // 상태
+  isImportSectionDialogOpen, setIsImportSectionDialogOpen,
+  isImportFieldDialogOpen, setIsImportFieldDialogOpen,
+  selectedImportSectionId, setSelectedImportSectionId,
+  selectedImportFieldId, setSelectedImportFieldId,
+  importFieldTargetSectionId, setImportFieldTargetSectionId,
+  // 핸들러
+  handleImportSection,
+  handleImportField,
+  handleCloneSection,
+}
+```
+
+#### 3. `useReorderManagement` (~60줄 분리)
+
+**분리 대상:**
+- moveSection (650-668줄)
+- moveField (672-702줄)
+
+**반환값:**
+```typescript
+{
+  moveSection: (dragIndex: number, hoverIndex: number) => Promise<void>;
+  moveField: (sectionId: number, dragFieldId: number, hoverFieldId: number) => Promise<void>;
+}
+```
+
+#### 4. `useDeleteManagement` (~50줄 분리)
+
+**분리 대상:**
+- handleDeletePageWithTracking (582-588줄)
+- handleDeleteSectionWithTracking (591-597줄)
+- handleUnlinkFieldWithTracking (601-609줄)
+- handleResetAllData (705-743줄)
+
+**반환값:**
+```typescript
+{
+  handleDeletePage: (pageId: number) => void;
+  handleDeleteSection: (pageId: number, sectionId: number) => void;
+  handleUnlinkField: (pageId: string, sectionId: string, fieldId: string) => Promise<void>;
+  handleResetAllData: () => void;
+}
+```
+
+### Phase 2: UI 컴포넌트 분리 (2개)
+
+#### 1. `AttributeTabContent` (~400줄 분리)
+
+**분리 대상:**
+- 속성 탭 내용 (807-1331줄)
+- 단위/재질/표면처리 반복 UI 통합
+
+**Props:**
+```typescript
+interface AttributeTabContentProps {
+  activeAttributeTab: string;
+  attributeSubTabs: AttributeSubTab[];
+  unitOptions: UnitOption[];
+  materialOptions: MaterialOption[];
+  surfaceTreatmentOptions: SurfaceTreatmentOption[];
+  customAttributeOptions: Record<string, Option[]>;
+  attributeColumns: Record<string, Column[]>;
+  itemMasterFields: ItemMasterField[];
+  // 핸들러들...
+}
+```
+
+#### 2. `ItemMasterDialogs` (~280줄 분리)
+
+**분리 대상:**
+- 13개 다이얼로그 렌더링 (1442-1797줄)
+
+**Props:**
+```typescript
+interface ItemMasterDialogsProps {
+  // 모든 다이얼로그 관련 props
+}
+```
+
+### Phase 3: 코드 정리
+
+1. **래퍼 함수 제거** (~30줄)
+   - `handleAddSectionWrapper` 등을 훅 내부로 이동
+   - `selectedPage`를 훅 파라미터로 전달
+
+2. **unused 변수 정리**
+   - `_mounted`, `_isLoading` 등 제거
+
+3. **Import 최적화**
+   - 사용하지 않는 import 제거
+
+---
+
+## 예상 결과
+
+### 줄 수 변화
+
+| 항목 | 현재 | 분리 후 |
+|------|------|---------|
+| Import | 61 | 40 |
+| 상수 | 28 | 28 |
+| 훅 사용 | 160 | 60 |
+| useMemo | 75 | 75 |
+| 상태/Effect | 130 | 20 |
+| 핸들러 | 225 | 30 |
+| UI 렌더링 | 1,053 | 300 |
+| **합계** | **1,799** | **~550** |

+- [ ] 반복 코드 통합
+
+### Step 6: ItemMasterDialogs 컴포넌트 분리

+
+### Step 7: 정리 및 테스트

+
+## 리스크 및 주의사항
+
+1. **Context 의존성**: 훅들이 `useItemMaster` Context에 의존
+   - 해결: 필요한 함수만 훅 파라미터로 전달
+
+2. **상태 공유**: 여러 훅에서 동일 상태 사용
+   - 해결: 공통 상태는 메인 컴포넌트에서 관리
+
+3. **타입 호환성**: 기존 훅의 setter 타입 문제
+   - 해결: `as any` 임시 사용 또는 타입 수정
+
+4. **테스트**: 페이지 기능이 많아 수동 테스트 필요
+   - 해결: 체크리스트 작성하여 순차 테스트
+
+---
+
+## 다음 단계
+
+1. 이 계획서 확인 후 작업 시작
+2. Step 1부터 순차 진행
+3. 각 Step 완료 후 빌드 확인
+4. 최종 수동 테스트
