+# 품목기준관리 Zustand 리팩토링 설계서
+
+> **핵심 목표**: 모든 기능을 100% 동일하게 유지하면서, 수정 절차를 간단화
+
+## 📌 핵심 원칙
+
+```
+⚠️ 중요: 모든 품목기준관리 기능을 그대로 가져와야 함
+⚠️ 중요: 수정 절차 간단화가 핵심 (3방향 동기화 → 1곳 수정)
+⚠️ 중요: 모든 기능이 정확히 동일하게 작동해야 함

+
+## 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

+    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;

+}
+```
+
+### 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 |
+| **동기화** | 1곳 수정으로 모든 뷰 업데이트 |
+| **코드량** | CRUD 함수 코드 50% 이상 감소 |
+| **버그** | 데이터 불일치 버그 0건 |
+| **성능** | 기존 대비 동등 또는 향상 |

+# 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

+
+```
+마이그레이션 준비해줘 - 기존 페이지를 테스트 페이지로 대체
+```
+
+---
+
+## 남은 작업
+
+### 우선순위 높음
+1. **실사용 테스트**: 테스트 페이지에서 실제 데이터로 CRUD 테스트
+2. **버그 수정**: 발견되는 버그 즉시 수정
+3. **마이그레이션**: 테스트 완료 후 기존 페이지 대체
+
+### 선택적 (필요 시)
+4. **Phase D-2**: 커스텀 탭 관리 (속성 하위 탭 추가/수정/삭제)
+   - 기존 페이지에서도 사용되지 않는 기능
+   - 백엔드 API 연동 필요
