+```markdown
+<thinking>
+[Model: Claude Opus 4.1] → [Agent: superport-api-architect]
+[Analysis Phase: API Architecture Integration Analysis]
+
+1. Problem Decomposition:
+   - Core challenge: Resolve frontend DTO and backend schema mismatch
+   - Sub-problems: vendors→models→equipments FK relationships, equipment_history missing
+   - Dependencies: PostgreSQL schema, Rust API, Flutter DTO
+
+2. Constraint Analysis:
+   - Technical: Maintain existing system stability, gradual migration
+   - Business: Support Korean ERP business processes, real-time data synchronization
+   - Resource: Single server environment (43.201.34.104:8080)
+   - Timeline: Improvement during non-stop service operation
+
+3. Solution Architecture:
+   - Approach A: Backend-first (schema-based API redesign)
+   - Approach B: Frontend-first (current DTO-based backend modification)
+   - Hybrid: Simultaneous modification (recommended) - OpenAPI spec-based synchronization
+   - Selection Rationale: Ensure bidirectional compatibility
+
+4. Risk Assessment:
+   - High Risk: Data loss, API compatibility failure
+   - Medium Risk: Performance degradation, user experience disruption
+   - Mitigation: Step-by-step verification, parallel environment testing
+
+5. Implementation Path:
+   - Phase 1: OpenAPI spec definition and documentation
+   - Phase 2: Add missing entities and endpoints
+   - Phase 3: Integration testing and optimization

-            icon: Icon(Icons.delete),
-            onPressed: () => _handleDelete(item),
-          ),
-        ],
-      )),
-    ],
-  )).toList(),
-);
-```
-
-## 4. 서비스 레이어 패턴
-
-### 4.1 Mock 데이터 서비스
-```dart
-class MockDataService {
-  static final MockDataService _instance = MockDataService._internal();
-  factory MockDataService() => _instance;
-  MockDataService._internal();
-  
-  // 데이터 저장소
-  final List<Model> _items = [];
-  
-  // CRUD 메서드
-  Future<List<Model>> getItems() async {
-    await Future.delayed(Duration(milliseconds: 300)); // 네트워크 지연 시뮬레이션
-    return List.from(_items);
-  }
-  
-  Future<Model> addItem(Model item) async {
-    await Future.delayed(Duration(milliseconds: 300));
-    _items.add(item);
-    return item;
-  }
-  
-  Future<void> updateItem(String id, Model item) async {
-    await Future.delayed(Duration(milliseconds: 300));
-    final index = _items.indexWhere((i) => i.id == id);
-    if (index != -1) {
-      _items[index] = item;
-    }
-  }
-  
-  Future<void> deleteItem(String id) async {
-    await Future.delayed(Duration(milliseconds: 300));
-    _items.removeWhere((i) => i.id == id);
-  }
-}
-```
-
-## 5. 유틸리티 패턴
-
-### 5.1 Validator
-```dart
-class Validators {
-  static String? required(String? value, {String? fieldName}) {
-    if (value == null || value.trim().isEmpty) {
-      return '${fieldName ?? '이 필드'}는 필수입니다.';
-    }
-    return null;
-  }
-  
-  static String? email(String? value) {
-    if (value == null || value.isEmpty) return null;
-    final emailRegex = RegExp(r'^[\w-\.]+@([\w-]+\.)+[\w-]{2,4}$');
-    if (!emailRegex.hasMatch(value)) {
-      return '올바른 이메일 형식이 아닙니다.';
-    }
-    return null;
-  }
-}
-```
-
-### 5.2 상수 정의
-```dart
-class Routes {
-  static const String home = '/';
-  static const String login = '/login';
-  static const String equipment = '/equipment';
-  // ...
-}
-
-class AppColors {
-  static const Color primary = Color(0xFF3B82F6);
-  static const Color secondary = Color(0xFF64748B);
-  // ...
-}
-```
-
-## 6. 베스트 프랙티스
-
-### 6.1 일반 규칙
-1. **단일 책임 원칙**: 각 클래스/함수는 하나의 책임만 가져야 함
-2. **DRY 원칙**: 코드 중복을 피하고 재사용 가능한 컴포넌트 작성
-3. **명확한 네이밍**: 변수, 함수, 클래스명은 용도를 명확히 표현
-4. **일관성**: 프로젝트 전체에서 동일한 패턴과 스타일 사용
-
-### 6.2 Flutter 특화
-1. **const 생성자 사용**: 가능한 모든 위젯에 const 사용
-2. **Key 사용**: 리스트나 동적 위젯에는 적절한 Key 제공
-3. **BuildContext 주의**: async 작업 후 context 사용 시 mounted 체크
-4. **메모리 누수 방지**: Controller, Stream 등은 dispose에서 정리
-
-### 6.3 리디자인 관련
-1. **테마 시스템 사용**: 하드코딩된 스타일 대신 ShadcnTheme 사용
-2. **컴포넌트 재사용**: shadcn_components의 표준 컴포넌트 활용
-3. **일관된 레이아웃**: AppLayoutRedesign으로 모든 화면 감싸기
-4. **반응형 디자인**: 다양한 화면 크기 고려
-
-## 7. 코드 예제
-
-### 7.1 완전한 리스트 화면 예제
-```dart
-// user_list_redesign.dart
-class UserListRedesign extends StatefulWidget {
-  const UserListRedesign({Key? key}) : super(key: key);
-  
-  @override
-  State<UserListRedesign> createState() => _UserListRedesignState();

-          Text('사용자가 없습니다', style: ShadcnTheme.typography.bodyMuted),
-        ],
-      ),

-),
-```
-
-## 성능 최적화 전략
-
-### 렌더링 최적화
-```dart
-// const 생성자 활용
-const SizedBox(width: 8),

-```dart
-// 불필요한 setState 방지
-if (_selectedStatus != newStatus) {
-  setState(() => _selectedStatus = newStatus);
-}
-
-// 컨트롤러 재사용
-late final EquipmentListController _controller;
-```
-
-## 테스트 전략
-
-### 단위 테스트
-```dart
-// 선택 기능 테스트
-test('equipment selection works correctly', () {
-  controller.selectEquipment(1, 'I', true);
-  expect(controller.getSelectedInStockCount(), 1);
-});
-
-// 검색 기능 테스트
-test('search filters equipment correctly', () {
-  final filtered = controller.searchEquipments('Dell');
-  expect(filtered.length, greaterThan(0));
-});
-```
-
-### 위젯 테스트
-```dart
-// UI 렌더링 테스트
-testWidgets('equipment table renders correctly', (tester) async {
-  await tester.pumpWidget(EquipmentListRedesign());
-  expect(find.byType(DataTable), findsOneWidget);
-});
-
-// 상호작용 테스트
-testWidgets('checkbox selection updates UI', (tester) async {
-  await tester.tap(find.byType(Checkbox).first);
-  await tester.pump();
-  expect(find.text('1개 선택됨'), findsOneWidget);
-});
-```
-
-## 마이그레이션 체크리스트
-
-### Phase 1 완료 기준
-- [ ] 체크박스 선택 기능 구현 및 테스트
-- [ ] 편집/삭제 버튼 구현 및 테스트
-- [ ] 상세 정보 표시 구현 및 테스트
-- [ ] 기존 equipment_list와 기능 동일성 확인
-
-### Phase 2 완료 기준
-- [ ] 라우트별 액션 버튼 구현
-- [ ] 검색 기능 확장 구현
-- [ ] 출고 정보 표시 구현
-- [ ] 모든 액션 핸들러 작동 확인
-
-### Phase 3 완료 기준
-- [ ] 상세/간소화 뷰 전환 구현
-- [ ] 반응형 레이아웃 구현
-- [ ] 성능 최적화 완료
-- [ ] 전체 기능 통합 테스트 통과
-
-## 리스크 및 대응 방안
-
-### 잠재 리스크
-1. **상태 관리 복잡도**: 선택 상태와 필터 상태의 동기화
-   - 대응: 명확한 상태 플로우 문서화
-
-2. **UI 일관성**: shadcn 스타일과 기존 기능의 조화
-   - 대응: 디자인 시스템 엄격 준수
-
-3. **성능 이슈**: 대량 데이터 처리 시 렌더링 지연
-   - 대응: 가상 스크롤링 도입 검토

-══╡ EXCEPTION CAUGHT BY RENDERING LIBRARY ╞═════════════════════════════════════════════════════════
-The following assertion was thrown during performLayout():
-RenderFlex children have non-zero flex but incoming width constraints are unbounded.
-When a row is in a parent that does not provide a finite width constraint, for example if it is in a
-horizontal scrollable, it will try to shrink-wrap its children along the horizontal axis. Setting a
-flex on a child (e.g. using Expanded) indicates that the child is to expand to fill the remaining
-space in the horizontal direction.
-These two directives are mutually exclusive. If a parent is to shrink-wrap its child, the child
-cannot simultaneously expand to fit its parent.
-Consider setting mainAxisSize to MainAxisSize.min and using FlexFit.loose fits for the flexible
-children (using Flexible rather than Expanded). This will allow the flexible children to size
-themselves to less than the infinite remaining space they would otherwise be forced to take, and
-then will cause the RenderFlex to shrink-wrap the children rather than expanding to fit the maximum
-constraints provided by the parent.
-If this message did not help you determine the problem, consider using debugDumpRenderTree():
-  https://flutter.dev/to/debug-render-layer
-  https://api.flutter.dev/flutter/rendering/debugDumpRenderTree.html
-The affected RenderFlex is:

-  mainAxisSize: max, crossAxisAlignment: center, textDirection: ltr, verticalDirection: down, spacing: 0.0)
-The creator information is set to:
-  Row ← Padding ← DecoratedBox ← Container ← Column ← Padding ← DecoratedBox ← ConstrainedBox ←

-## 🎯 Mandatory Response Format
-
-Before starting any task, you MUST respond in the following format:
-
-```
-[Model Name]. I have reviewed all the following rules: [rule file list or categories]. Proceeding with the task. Master!
-```
-
-**Examples:**
-
-- `Claude Sonnet 4. I have reviewed all the following rules: development guidelines, class structure, testing rules. Proceeding with the task. Master!`
-- For extensive rules: `coding style, class design, exception handling, testing rules` (categorized summary)
-
-## 🚀 Mandatory 3-Phase Task Process
-
-### Phase 1: Codebase Exploration & Analysis
-
-**Required Actions:**
-
-- Systematically discover ALL relevant files, directories, modules
-- Search for related keywords, functions, classes, patterns
-- Thoroughly examine each identified file
-- Document coding conventions and style guidelines
-- Identify framework/library usage patterns
-
-### Phase 2: Implementation Planning
-
-**Required Actions:**
-
-- Create detailed implementation roadmap based on Phase 1 findings
-- Define specific task lists and acceptance criteria per module
-- Specify performance/quality requirements
-
-### Phase 3: Implementation Execution
-
-**Required Actions:**
-
-- Implement each module following Phase 2 plan
-- Verify ALL acceptance criteria before proceeding
-- Ensure adherence to conventions identified in Phase 1
-
-## ✅ Core Development Principles
-
-### Language & Type Rules
-
-- **Write ALL code, variables, and names in English**
-- **Write ALL comments, documentation, prompts, and responses in Korean**
-- **Always declare types explicitly** for variables, parameters, and return values
-- Avoid `any`, `dynamic`, or loosely typed declarations (except when strictly necessary)
-- Define **custom types** when needed
-- Extract magic numbers and literals into named constants or enums
-
-### Naming Conventions
-
-|Element|Style|Example|
-|---|---|---|
-|Classes|`PascalCase`|`UserService`, `DataRepository`|
-|Variables/Methods|`camelCase`|`userName`, `calculateTotal`|
-|Files/Folders|`under_score_case`|`user_service.dart`, `data_models/`|
-|Environment Variables|`UPPERCASE`|`API_URL`, `DATABASE_PASSWORD`|
-
-**Critical Rules:**
-
-- **Boolean variables must be verb-based**: `isReady`, `hasError`, `canDelete`
-- **Function/method names start with verbs**: `executeLogin`, `saveUser`
-- Use meaningful, descriptive names
-- Avoid abbreviations unless widely accepted: `i`, `j`, `err`, `ctx`, `API`, `URL`
-
-## 🔧 Function & Method Design
-
-### Function Structure Principles
-
-- **Keep functions short and focused** (≤20 lines recommended)
-- **Avoid blank lines inside functions**
-- **Follow Single Responsibility Principle**
-- **Use verb + object format** for naming:
-    - Boolean return: `isValid`, `canRetry`, `hasPermission`
-    - Void return: `executeLogin`, `saveUser`, `startAnimation`
-
-### Function Optimization Techniques
-
-- Use **early returns** to avoid nested logic
-- Extract logic into helper functions
-- Prefer **arrow functions** for short expressions (≤3 lines)
-- Use **named functions** for complex logic
-- Minimize null checks by using **default values**
-- Minimize parameters using **RO-RO pattern** (Receive Object – Return Object)
-
-## 📦 Data & Class Design
-
-### Class Design Principles
-
-- **Strictly follow Single Responsibility Principle (SRP)**
-- **Favor composition over inheritance**
-- **Define interfaces/abstract classes** to establish contracts
-- **Prefer immutable data structures** (use `readonly`, `const`)
-
-### File Size Management
-
-- **Split by responsibility when exceeding 200 lines** (responsibility-based, not line-based)
-- ✅ **May remain as-is if**:
-    - Has **single clear responsibility**
-    - Is **easy to maintain**
-- 🔁 **Must split when**:
-    - Contains **multiple concerns**
-    - Requires **excessive scrolling**
-    - Patterns repeat across files
-    - Difficult for new developer onboarding
-
-### Class Recommendations
-
-- ≤ 200 lines (not mandatory)
-- ≤ 10 public methods
-- ≤ 10 properties
-
-### Data Model Design
-
-- Avoid excessive use of primitives — use **composite types or classes**
-- Move **validation logic inside data models** (not in business logic)
-
-## ❗ Exception Handling
-
-### Exception Usage Principles
-
-- Use exceptions only for **truly unexpected or critical issues**
-- **Catch exceptions only to**:
-    - Handle known failure scenarios
-    - Add useful context
-- Otherwise, let global handlers manage them
-
-## 🧪 Testing
-
-### Test Structure
-
-- Follow **Arrange–Act–Assert** pattern
-- Clear test variable naming: `inputX`, `mockX`, `actualX`, `expectedX`
-- **Write unit tests for every public method**
-
-### Test Doubles Usage
-
-- Use **test doubles** (mock/fake/stub) for dependencies
-- Exception: allow real use of **lightweight third-party libraries**
-
-### Integration Testing
-
-- Write **integration tests per module**
-- Follow **Given–When–Then** structure
-- Ensure **100% test pass rate in CI** and **apply immediate fixes** for failures
-
-## 🧠 Error Analysis & Rule Documentation
-
-### Mandatory Process When Errors Occur
-
-1. **Analyze root cause in detail**
-2. **Document preventive rule in `.cursor/rules/error_analysis.mdc`**
-3. **Write in English including**:
-    - Error description and context
-    - Cause and reproducibility steps
-    - Resolution approach
-    - Rule for preventing future recurrences
-    - Sample code and references to related rules
-
-### Rule Writing Standards
-
-```markdown
----
-description: Clear, one-line description of what the rule enforces
-globs: path/to/files/*.ext, other/path/**/*
-alwaysApply: boolean
----
-
-**Main Points in Bold**
-- Sub-points with details
-- Examples and explanations
-```
-
-## 🏗️ Architectural Guidelines
-
-### Clean Architecture Compliance
-
-- **Layered structure**: `modules`, `controllers`, `services`, `repositories`, `entities`
-- Apply **Repository Pattern** for data abstraction
-- Use **Dependency Injection** (`getIt`, `inject`, etc.)
-- Controllers handle business logic (not view processing)
-
-### Code Structuring
-
-- **One export or public declaration per file**
-- Centralize constants, error messages, and configuration
-- Make **all shared logic reusable** and place in dedicated helper modules
-
-## 🌲 UI Structure & Component Design
-
-### UI Optimization Principles
-
-- **Avoid deeply nested widget/component trees**:
-    - Flatten hierarchy for **better performance and readability**
-    - Easier **state management and testability**
-- **Split large components into small, focused widgets/components**
-- Use `const` constructors (or equivalents) for performance optimization
-- Apply clear **naming and separation** between view, logic, and data layers
-
-## 📈 Continuous Rule Improvement
-
-### Rule Improvement Triggers
-
-- New code patterns not covered by existing rules
-- Repeated similar implementations across files
-- Common error patterns that could be prevented
-- New libraries or tools being used consistently
-- Emerging best practices in the codebase
-
-### Rule Update Criteria
-
-**Add New Rules When:**
-
-- A new technology/pattern is used in 3+ files
-- Common bugs could be prevented by a rule
-- Code reviews repeatedly mention the same feedback
-
-**Modify Existing Rules When:**
-
-- Better examples exist in the codebase
-- Additional edge cases are discovered
-- Related rules have been updated

+# API 인벤토리 및 활용도 분석 보고서
+
+> 작성일: 2025년 8월 26일
+> 대상: Superport ERP 시스템 (Flutter Frontend + Rust Backend)
+
+## 1. 백엔드 API 총 인벤토리
+
+### 백엔드 API 엔드포인트 총계: **83개**
+
+| 모듈 | 엔드포인트 수 | 인증 요구 사항 |

+| **Rents** | ❌ **미사용** | - |
+| **Administrators** | ❌ **미사용** | - |
+| **Zipcodes** | ❌ **미사용** | - |
+
+## 3. API 활용률 계산
+
+### 전체 활용률
+- **백엔드 총 API**: 83개
+- **프론트엔드 사용 추정**: 약 35개
+- **활용률**: **42.2%**
+
+### 모듈별 활용률 상세
+
+| 모듈 | 백엔드 API | 프론트엔드 사용 | 활용률 |
+|------|-----------|--------------|--------|
+| Auth | 5개 | 3개 | 60% |
+| Users | 6개 | 5개 | 83% |
+| Companies | 6개 | 4개 | 67% |
+| Equipment | 9개 | 5개 | 56% |
+| Warehouses | 6개 | 5개 | 83% |
+| Lookups | 4개 | 2개 | 50% |
+| **Vendors** | 7개 | 0개 | **0%** |
+| **Models** | 6개 | 0개 | **0%** |
+| **Equipment History** | 10개 | 0개 | **0%** |
+| **Maintenances** | 6개 | 0개 | **0%** |
+| **Rents** | 6개 | 0개 | **0%** |
+| **Administrators** | 6개 | 0개 | **0%** |
+| **Zipcodes** | 5개 | 0개 | **0%** |
+
+## 4. 주요 불일치 사항
+
+### 🚨 Critical: 완전 미구현 모듈 (43개 API / 52%)
+1. **Vendors (제조사 관리)**: 백엔드 구현 완료, 프론트엔드 완전 미구현
+2. **Models (모델 관리)**: 백엔드 구현 완료, 프론트엔드 완전 미구현
+3. **Equipment History (재고 추적)**: 백엔드 구현 완료, 프론트엔드 완전 미구현
+4. **Maintenances (유지보수)**: 백엔드 구현 완료, 프론트엔드 완전 미구현
+5. **Rents (임대 관리)**: 백엔드 구현 완료, 프론트엔드 완전 미구현
+6. **Administrators**: 백엔드 구현 완료, 프론트엔드 완전 미구현
+7. **Zipcodes (우편번호)**: 백엔드 구현 완료, 프론트엔드 완전 미구현
+
+### ⚠️ Warning: 엔드포인트 경로 불일치
+1. **Equipment**:
+   - 백엔드: `/equipments` (복수형)
+   - 프론트엔드: `/equipment` (단수형)
+
+2. **Warehouse**:
+   - 백엔드: `/warehouses`
+   - 프론트엔드: `/warehouse-locations`
+
+### ⚠️ Warning: 존재하지 않는 API 호출
+프론트엔드가 정의했지만 백엔드에 없는 엔드포인트:
+- `/licenses/*` (라이선스 관련 모든 API)
+- `/overview/*` (대시보드 통계 관련)
+- `/files/*` (파일 업로드/다운로드)
+- `/reports/*` (보고서 생성)
+- `/bulk/*` (대량 처리)
+- `/audit-logs` (감사 로그)
+- `/backup/*` (백업/복원)
+
+## 5. 영향도 분석
+
+### 비즈니스 임팩트
+- **High Impact**: Equipment History 미구현으로 재고 추적 불가능
+- **High Impact**: Maintenances 미구현으로 유지보수 관리 불가능
+- **Medium Impact**: Vendors/Models 미구현으로 장비 카탈로그 관리 제한
+- **Low Impact**: Zipcodes 미구현 (주소 검증 제한)
+
+### 기술 부채
+- 43개 API (52%)가 구현되어 있지만 전혀 사용되지 않음
+- 프론트엔드가 존재하지 않는 API를 참조하고 있음 (License 등)
+- API 경로 불일치로 인한 잠재적 오류 위험
+
+## 6. 권장 사항
+
+### 즉시 조치 필요 (Priority 1)
+1. Equipment History API 프론트엔드 구현 (재고 관리 핵심)
+2. Maintenances API 프론트엔드 구현 (유지보수 관리 핵심)
+3. API 경로 통일 (equipment → equipments)
+
+### 단기 개선 (Priority 2)
+1. Vendors/Models API 프론트엔드 구현
+2. License → Maintenance 마이그레이션
+3. 미사용 API 정의 제거
+
+### 장기 개선 (Priority 3)
+1. Rents API 구현 (임대 기능)
+2. Administrators API 구현 (관리자 관리)
+3. 파일 업로드/보고서 기능 백엔드 구현
+
+## 7. 결론
+
+**현재 API 활용률 42.2%**는 시스템이 절반 이하의 기능만 사용하고 있음을 의미합니다. 특히 재고 관리(Equipment History)와 유지보수(Maintenances) 같은 핵심 기능이 완전히 누락되어 있어, ERP 시스템으로서의 완성도가 매우 낮은 상태입니다.
+
+백엔드는 이미 완성도 높게 구현되어 있으므로, 프론트엔드의 API 통합 작업이 시급히 필요합니다.

+# 코드 정리 및 미사용 파일 분석 보고서
+
+> 작성일: 2025년 8월 26일
+> 분석 도구: flutter analyze, grep, code dependency analysis
+
+## 1. 미사용 파일 현황
+
+### 1.1 License 관련 잔여 파일 (삭제 필요)
+```
+lib/core/extensions/license_expiry_summary_extensions.dart
+lib/data/models/dashboard/license_expiry_summary.dart
+lib/data/models/dashboard/license_expiry_summary.g.dart
+lib/data/models/dashboard/license_expiry_summary.freezed.dart
+lib/data/models/dashboard/expiring_license.dart
+lib/data/models/dashboard/expiring_license.g.dart
+lib/data/models/dashboard/expiring_license.freezed.dart
+lib/screens/overview/widgets/license_expiry_alert.dart
+```
+
+**이유**: License → Maintenance 마이그레이션 후 남은 잔여 파일
+
+### 1.2 마이그레이션 임시 파일 (검토 후 삭제)
+```
+lib/core/migrations/license_to_maintenance_migration.dart
+lib/core/migrations/maintenance_data_validator.dart
+lib/core/migrations/execute_migration.dart
+lib/core/migrations/equipment_category_migration.dart (예상)
+```
+
+**이유**: 일회성 마이그레이션 스크립트
+
+### 1.3 미구현 API 관련 파일 (삭제 고려)
+```
+lib/data/models/equipment/equipment_history_dto.dart (미사용)
+lib/data/models/maintenance_dto.dart (미사용)
+lib/data/models/vendor_dto.dart (미사용)
+lib/data/models/model_dto.dart (미사용)
+```
+
+**이유**: 백엔드 API는 있지만 프론트엔드에서 전혀 사용하지 않음
+
+## 2. Dead Code 현황
+
+### 2.1 미사용 메서드 (27개)
+| 파일 | 메서드 | 라인 |
+|-----|--------|-----|
+| equipment_list.dart | _loadData() | 95 |
+| equipment_list.dart | _onEquipmentSelected() | 147 |
+| equipment_list.dart | _handleHistory() | 443 |
+| equipment_list.dart | _showEditDialog() | 1280 |
+| equipment_list.dart | _showDeleteDialog() | 1285 |
+| equipment_list.dart | _getPagedEquipments() | 1321 |
+| equipment_out_form.dart | _getUsersForCompany() | 808 |
+| equipment_history_panel.dart | _buildUpcomingFeature() | 405 |
+| overview_screen.dart | _buildStatusItem() | 534 |
+| user_list.dart | _getCompanyName() | 58 |
+| user_service.dart | _mapRoleFromApi() | 203 |
+
+### 2.2 미사용 필드 (11개)
+| 파일 | 필드 | 라인 |
+|-----|------|-----|
+| equipment_in_form_controller.dart | _warehouseService | 18 |
+| equipment_in_form_controller.dart | _companyService | 19 |
+| equipment_out_form_controller.dart | _equipmentService | 14 |
+| equipment_list.dart | _scrollController | 30 |
+| stock_in_form.dart | _status | 23 |
+| number_formatter.dart | _percentFormat | 14 |
+
+## 3. 중복 코드 패턴
+
+### 3.1 API 에러 처리 중복
+```dart
+// 40+ 파일에서 동일한 패턴 반복
+} on DioException catch (e) {
+  throw ServerException(
+    message: e.response?.data['message'] ?? 'Network error occurred',
+    statusCode: e.response?.statusCode,
+  );
+}
+```
+
+**개선안**: 공통 에러 핸들러로 추출
+
+### 3.2 페이지네이션 로직 중복
+```dart
+// 15+ 파일에서 유사한 코드
+final pagination = response.data['pagination'] ?? {};
+final listData = {
+  'items': dataList,
+  'total': pagination['total'] ?? 0,
+  // ...
+};
+```
+
+**개선안**: 페이지네이션 유틸리티 클래스 생성
+
+### 3.3 폼 검증 로직 중복
+```dart
+// 모든 폼에서 반복
+validator: (value) {
+  if (value == null || value.isEmpty) {
+    return '필수 입력 항목입니다';
+  }
+  return null;
+}
+```
+
+**개선안**: 공통 Validator 클래스 사용
+
+## 4. Import 정리 필요
+
+### 4.1 Unused Imports (23개 파일)
+```dart
+// 예시
+import 'package:superport/models/license_model.dart'; // 미사용
+import 'dart:async'; // 미사용
+import 'package:flutter/foundation.dart'; // 미사용
+```
+
+### 4.2 Duplicate Imports (5개 파일)
+```dart
+import 'dart:async';
+// ... other imports ...
+import 'dart:async'; // 중복
+```
+
+## 5. 구조적 개선 필요 사항
+
+### 5.1 순환 의존성
+```
+equipment_service ← equipment_controller ← equipment_service
+```
+
+### 5.2 과도한 파일 크기
+- equipment_list.dart: 1,400+ 라인 (분할 필요)
+- company_form.dart: 800+ 라인 (분할 필요)
+
+### 5.3 잘못된 위치의 파일
+```
+lib/models/ (legacy)
+lib/data/models/ (새로운 구조)
+// 두 곳에 모델이 혼재
+```
+
+## 6. 삭제 권장 파일 목록
+
+### 즉시 삭제 가능 (안전)
+```bash
+# License 관련 잔여 파일
+rm lib/core/extensions/license_expiry_summary_extensions.dart
+rm lib/data/models/dashboard/license_expiry_summary.*
+rm lib/data/models/dashboard/expiring_license.*
+rm lib/screens/overview/widgets/license_expiry_alert.dart
+
+# 빈 파일 또는 템플릿
+rm lib/data/models/.gitkeep (있다면)
+rm lib/screens/.DS_Store (있다면)
+
+# 미사용 테스트 파일
+rm test/integration/license_integration_test.dart
+```
+
+### 검토 후 삭제 권장
+```bash
+# 마이그레이션 완료 확인 후
+rm -rf lib/core/migrations/
+
+# 미사용 DTO (백엔드 API 미사용)
+rm lib/data/models/equipment_history_dto.*
+rm lib/data/models/maintenance_dto.*
+rm lib/data/models/vendor_dto.*
+rm lib/data/models/model_dto.*
+```
+
+### 리팩토링 필요
+```bash
+# models 디렉토리 통합
+mv lib/models/* lib/data/models/
+rmdir lib/models/
+
+# 중복 서비스 통합
+# lib/services/ → lib/data/repositories/로 이동
+```
+
+## 7. 코드 품질 메트릭
+
+### Before Cleanup
+- Flutter analyze issues: 64개
+- Unused code: 38개
+- Dead code: 11개
+- Duplicate code blocks: 15+
+- Total lines of code: ~45,000
+
+### After Cleanup (예상)
+- Flutter analyze issues: ~30개
+- Unused code: 0개
+- Dead code: 0개
+- Duplicate code blocks: 5개
+- Total lines of code: ~38,000 (15% 감소)
+
+## 8. 정리 실행 계획
+
+### Phase 1: 안전한 정리 (즉시 가능)
+```bash
+#!/bin/bash
+# cleanup_phase1.sh
+
+# 1. License 관련 파일 삭제
+find lib -name "*license*" -type f | grep -v maintenance | xargs rm -f
+
+# 2. Dead code 제거
+flutter analyze | grep "unused_element" | cut -d':' -f1 | xargs -I {} sed -i '' '/unused_element/d' {}
+
+# 3. Unused imports 제거
+dart fix --apply
+```
+
+### Phase 2: 구조 개선 (신중한 검토 필요)
+1. models 디렉토리 통합
+2. 순환 의존성 해결
+3. 대형 파일 분할
+
+### Phase 3: 코드 품질 개선
+1. 중복 코드 추출
+2. 공통 유틸리티 생성
+3. 테스트 커버리지 개선
+
+## 9. 위험 분석
+
+### Low Risk (즉시 가능)
+- License 관련 파일 삭제
+- Unused imports 제거
+- Dead code 제거
+
+### Medium Risk (테스트 필요)
+- 미사용 DTO 삭제
+- 중복 코드 통합
+
+### High Risk (신중한 검토)
+- models 디렉토리 재구성
+- 서비스 레이어 통합
+- 대형 파일 분할
+
+## 10. 권장사항
+
+### 즉시 실행
+1. `dart fix --apply` 실행
+2. License 관련 파일 모두 삭제
+3. Dead code 제거
+
+### 단기 계획
+1. 미사용 API 관련 파일 정리
+2. Import 정리 자동화 설정
+3. 코드 포맷터 규칙 통일
+
+### 장기 계획
+1. 아키텍처 개선 (Clean Architecture 완전 적용)
+2. 모듈화 강화
+3. 테스트 커버리지 80% 달성
+
+## 결론
+
+현재 코드베이스는 **약 15-20%의 불필요한 코드**를 포함하고 있으며, 특히 License 시스템 잔여물과 미구현 API 관련 파일들이 주요 원인입니다.
+
+정리 작업을 통해:
+- **코드 크기 15% 감소**
+- **빌드 시간 10% 개선**
+- **유지보수성 향상**
+
+을 기대할 수 있습니다.

+# API 호환성 및 논리적 오류 검증 보고서
+
+> 작성일: 2025년 8월 26일
+> 분석 범위: Frontend-Backend API 호환성 및 비즈니스 로직 검증
+
+## 1. Critical 호환성 문제
+
+### 🔴 1.1 Equipment 데이터 구조 불일치
+
+#### 문제점
+프론트엔드가 두 가지 상충되는 데이터 모델을 동시에 사용:
+```dart
+// equipment_in_form.dart
+// 1. Legacy 카테고리 시스템
+CategoryCascadeFormField(
+  category1: _controller.category1,
+  category2: _controller.category2,
+  category3: _controller.category3,
+)
+
+// 2. 새로운 Vendor-Model 시스템 
+EquipmentVendorModelSelector(
+  initialVendorId: _controller.vendorId,
+  initialModelId: _controller.modelsId,
+)
+```
+
+#### 백엔드 기대값
+```rust
+// 백엔드는 models_id FK만 사용
+pub struct Equipment {
+    pub models_id: i32,  // Foreign Key to models table
+    // category1, category2, category3 필드 없음
+}
+```
+
+#### 영향도
+- **데이터 무결성 파괴**: 같은 화면에서 두 가지 다른 분류 체계 사용
+- **API 호출 실패 위험**: 백엔드가 기대하지 않는 필드 전송
+- **사용자 혼란**: 어떤 입력이 실제로 저장되는지 불명확
+
+### 🔴 1.2 API 경로 불일치
+
+| 기능 | 프론트엔드 경로 | 백엔드 경로 | 상태 |
+|-----|---------------|------------|------|
+| 장비 | `/equipment` | `/equipments` | ❌ 불일치 |
+| 창고 | `/warehouse-locations` | `/warehouses` | ❌ 불일치 |
+| 라이선스 | `/licenses` | 존재하지 않음 | ❌ 404 에러 |
+| 유지보수 | 구현 안됨 | `/maintenances` | ❌ 미사용 |
+
+### 🔴 1.3 필드명 케이스 불일치
+
+```dart
+// 프론트엔드 (camelCase)
+{
+  "equipmentNumber": "EQ-001",
+  "serialNumber": "SN12345",
+  "purchaseDate": "2025-08-26"
+}
+
+// 백엔드 기대값 (snake_case)
+{
+  "equipment_number": "EQ-001",
+  "serial_number": "SN12345",
+  "purchase_date": "2025-08-26"
+}
+```
+
+## 2. 논리적 오류 및 알고리즘 문제
+
+### 🔴 2.1 재고 관리 논리 부재
+
+#### 현재 상태
+- Equipment History API 완전 미구현
+- 입고/출고 추적 불가능
+- 재고 수량 관리 로직 없음
+
+#### 예상 문제
+```dart
+// equipment_remote_datasource.dart
+Future<EquipmentIoResponse> equipmentOut(EquipmentOutRequest request) {
+  // 재고 확인 로직 없음
+  // 출고 가능 수량 검증 없음
+  // 동시 출고 방지 로직 없음
+  return _apiClient.post('/equipment/out', data: request);
+}
+```
+
+### 🔴 2.2 중복 데이터 검증 미흡
+
+#### 시리얼 번호 중복 검사
+```dart
+// 프론트엔드에만 존재, 백엔드 검증 없음
+validator: (value) {
+  if (value.trim().isEmpty) {
+    return '장비 번호는 필수입니다';
+  }
+  // 중복 검사 로직 없음
+  return null;
+}
+```
+
+### 🔴 2.3 트랜잭션 처리 부재
+
+#### 문제 시나리오
+```dart
+// 장비 생성 + 초기 재고 입고를 별도 API로 호출
+await createEquipment(request);  // 성공
+await createEquipmentHistory(historyRequest);  // 실패시?
+// 롤백 로직 없음 → 데이터 불일치 발생
+```
+
+## 3. 페이지네이션 로직 불일치
+
+### 프론트엔드 기대값
+```dart
+{
+  'page': 1,
+  'per_page': 20,
+  'total': 100,
+  'total_pages': 5
+}
+```
+
+### 백엔드 실제 응답
+```json
+{
+  "pagination": {
+    "page": 1,
+    "per_page": 20,
+    "total": 100,
+    "total_pages": 5
+  }
+}
+```
+
+### 변환 로직 오류
+```dart
+// equipment_remote_datasource.dart
+final pagination = response.data['pagination'] ?? {};
+final listData = {
+  'items': dataList,
+  'total': pagination['total'] ?? 0,
+  'page': pagination['page'] ?? 1,  // 'current_page' 아님
+  // 하지만 다른 곳에서는 'current_page' 사용
+};
+```
+
+## 4. 한국어 검색 로직 문제
+
+### 현재 구현
+```dart
+// 단순 문자열 포함 검색만 지원
+if (search != null && search.isNotEmpty) 'search': search,
+```
+
+### 누락된 기능
+- 초성 검색 지원 안됨 (ㅅㅁㅅ → 삼성)
+- 공백 무시 검색 안됨 (삼 성 → 삼성)
+- 영한 혼용 검색 안됨 (samsung 갤럭시)
+
+## 5. 날짜/시간 처리 불일치
+
+### 프론트엔드
+```dart
+DateTime.now().toIso8601String()  // "2025-08-26T15:30:45.123Z"
+```
+
+### 백엔드 기대값
+```rust
+// NaiveDate expects "2025-08-26"
+// NaiveDateTime expects "2025-08-26 15:30:45"
+```
+
+## 6. 권한 체크 로직 누락
+
+### 현재 상태
+```dart
+// 모든 API 호출시 권한 체크 없음
+Future<void> deleteEquipment(int id) async {
+  // 삭제 권한 확인 없이 직접 호출
+  await _apiClient.delete('/equipment/$id');
+}
+```
+
+### 필요한 구현
+```dart
+// 권한 체크 후 호출
+if (currentUser.hasPermission('equipment.delete')) {
+  await _apiClient.delete('/equipment/$id');
+} else {
+  throw UnauthorizedException();
+}
+```
+
+## 7. 에러 처리 불일치
+
+### 백엔드 에러 형식
+```json
+{
+  "success": false,
+  "message": "Equipment not found",
+  "error_code": "EQUIPMENT_NOT_FOUND"
+}
+```
+
+### 프론트엔드 에러 처리
+```dart
+// error_code 무시, message만 사용
+throw ServerException(
+  message: e.response?.data['message'] ?? 'Network error occurred',
+  // error_code 처리 없음
+);
+```
+
+## 8. 비즈니스 로직 검증 오류
+
+### 8.1 회사 계층 구조
+- 백엔드: parent_company_id 지원
+- 프론트엔드: 플랫 구조만 지원
+
+### 8.2 유지보수 vs 라이선스
+- 백엔드: maintenances (equipment_history 기반)
+- 프론트엔드: licenses (독립 엔티티)
+
+### 8.3 장비 상태 관리
+```dart
+// 상태 전환 규칙 미구현
+changeEquipmentStatus(id, 'DISPOSED', reason) {
+  // ACTIVE → DISPOSED 직접 전환 허용
+  // 중간 상태 검증 없음
+}
+```
+
+## 9. 성능 문제
+
+### 9.1 N+1 쿼리 문제
+```dart
+// 장비 목록 조회 후 각 장비마다 추가 API 호출
+for (var equipment in equipments) {
+  final vendor = await getVendor(equipment.vendorId);  // N번 호출
+  final model = await getModel(equipment.modelId);     // N번 호출
+}
+```
+
+### 9.2 캐싱 전략 부재
+```dart
+// 매번 새로운 API 호출
+Future<List<LookupDto>> getLookups() async {
+  // 캐시 체크 없음
+  return await _apiClient.get('/lookups');
+}
+```
+
+## 10. 권장 수정 사항
+
+### Priority 1 (즉시)
+1. API 경로 통일 (equipment → equipments)
+2. 필드명 케이스 변환기 구현
+3. Equipment category 시스템 제거, models_id만 사용
+
+### Priority 2 (단기)
+1. Equipment History API 구현
+2. 트랜잭션 처리 로직 추가
+3. 중복 검증 로직 구현
+
+### Priority 3 (중기)
+1. 한국어 검색 개선
+2. 캐싱 전략 구현
+3. 권한 체크 시스템 구현
+
+## 결론
+
+현재 프론트엔드와 백엔드 간의 API 호환성은 **심각한 수준**입니다. 특히 Equipment 관련 데이터 구조 불일치와 재고 관리 로직 부재는 비즈니스 운영에 직접적인 영향을 미칠 수 있습니다.
+
+즉시 수정이 필요한 항목들을 우선적으로 처리하고, 체계적인 API 통합 테스트를 구축하는 것이 필요합니다.

+- ❌ 전역 포맷터 미활용
+
+### 1.3 ShadCN UI 한국화
+```dart
+✅ ShadToaster로 통일된 피드백
+✅ ShadDialog로 일관된 모달
+✅ 한국어 메시지 전체 적용
+```
+
+## 2. 🔴 누락된 필수 한국형 기능
+
+### 2.1 주소 검색 시스템 미구현
+**문제점**:
+- Daum 우편번호 API 미통합
+- 수동 주소 입력만 가능
+- 우편번호 검증 없음
+
+**현재 구현**:
+```dart
+// company_form.dart
+TextFormField(
+  decoration: InputDecoration(labelText: '주소'),
+  // 단순 텍스트 입력만 지원
+)
+```
+
+**필요한 구현**:
+```dart
+// 예상 구현
+AddressSearchField(
+  onAddressSelected: (address) {
+    _controller.zipcode = address.zipcode;
+    _controller.address1 = address.roadAddress;
+  },
+)
+```
+
+### 2.2 한국어 검색 최적화 부재
+**문제점**:
+- 초성 검색 미지원 (ㅅㅁㅅ → 삼성)
+- 공백 무시 검색 미지원
+- 영한 혼용 검색 미지원
+
+**현재 코드**:
+```dart
+// 단순 contains 검색만 지원
+if (search != null && search.isNotEmpty) {
+  filteredList = list.where((item) => 
+    item.name.contains(search)
+  ).toList();
+}
+```
+
+### 2.3 숫자 포맷팅 미적용
+**문제점**:
+- 금액 천 단위 구분 없음
+- 한국식 단위 미표시 (만/억/조)
+
+**현재 상태**:
+```dart
+Text('구매 가격: ${equipment.purchasePrice}')  // "50000000"
+```
+
+**개선 필요**:
+```dart
+Text('구매 가격: ${formatKoreanCurrency(equipment.purchasePrice)}')  // "5,000만원"
+```
+
+## 3. 🟡 부분적으로 구현된 기능
+
+### 3.1 날짜 표시
+**현재**: ISO 8601 형식 (2025-08-26T15:30:45)
+**개선 필요**: 한국식 표시 (2025년 8월 26일 (월) 오후 3시 30분)
+
+### 3.2 에러 메시지
+**잘된 점**: 모두 한국어로 표시
+**문제점**: 기술적 용어 그대로 노출
+
+```dart
+// 현재
+"Network error occurred"  // 영어 에러 그대로 노출
+
+// 개선 필요
+"네트워크 연결을 확인해 주세요"  // 사용자 친화적 메시지
+```
+
+## 4. 🔴 한국 비즈니스 워크플로우 미반영

+
+// 필요: 반응형 처리
+Container(
+  width: MediaQuery.of(context).size.width > 600 
+    ? 600 
+    : MediaQuery.of(context).size.width * 0.9,
+)
+```
+
+### 5.2 터치 타겟 크기 미달
+- 최소 48dp 권장, 현재 많은 버튼이 36dp
+- 스와이프 제스처 미지원
+- 롱프레스 컨텍스트 메뉴 없음
+
+## 6. 🔴 한국형 검증 규칙 누락

+```
+
+## 7. 🟡 성능 최적화 이슈
+
+### 7.1 리스트 가상 스크롤링 미구현
+```dart
+// 현재: 모든 항목 한번에 렌더링
+ListView(
+  children: items.map((item) => ItemWidget(item)).toList(),
+)
+
+// 필요: 가상 스크롤링
+ListView.builder(
+  itemCount: items.length,
+  itemBuilder: (context, index) => ItemWidget(items[index]),
+)
+```
+
+### 7.2 이미지 레이지 로딩 없음
+장비 사진 등 이미지 최적화 미구현
+
+## 8. 개선 우선순위

+### 9.3 숫자 포맷팅
+```dart
+class KoreanNumberFormatter {
+  static String format(int number) {
+    if (number >= 100000000) {
+      return '${(number / 100000000).toStringAsFixed(1)}억';
+    } else if (number >= 10000) {
+      return '${(number / 10000).toStringAsFixed(0)}만';
+    }
+    return NumberFormat('#,###').format(number);
+  }
+}
+```
+
+## 10. 결론

+```yaml
+심각도: 🟡 Medium
+영향도: 사용자 경험  
+문제:
+  - ShadCN UI 부분 구현 상태
+  - 커스텀 위젯과 표준 위젯 혼재
+  - 일관되지 않은 디자인 시스템
+```
+
+### ✅ **잘 구현된 부분**
+
+#### **1. Clean Architecture 기반 구조**
+```yaml
+✅ 레이어 분리 명확
+✅ 의존성 주입 (GetIt) 잘 설정됨

+✅ 브레이크포인트 기반 레이아웃
+✅ 접이식 사이드바
+✅ 모바일 최적화 고려
+```
+
+---
+
+## 🚀 9. 마이그레이션 우선순위
+
+### 🔥 **Phase 1: API 스키마 동기화 (Critical)**
+```yaml
+1. 누락 엔티티 DTO 생성:
+   - VendorDto + Repository + UseCase
+   - ModelDto + Repository + UseCase
+   - EquipmentHistoryDto + Repository + UseCase
+   - MaintenanceHistoryDto + Repository + UseCase (License 대체)
+   - RentDto + Repository + UseCase
+
+2. 기존 DTO 수정:
+   - EquipmentDto: modelsId 추가, category1/2/3 제거
+   - CompanyDto: zipcodeZipcode, isActive 추가
+
+3. Service → Repository 마이그레이션:
+   - CompanyService → CompanyRepository
+   - EquipmentService → EquipmentRepository
+```
+
+### 🎨 **Phase 2: ShadCN UI 통합**
+```yaml
+1. 완전한 ShadCN 컴포넌트 구현:
+   - ShadInput, ShadSelect, ShadDatePicker
+   - ShadTable, ShadDialog, ShadSheet
+   - ShadTabs, ShadCheckbox, ShadProgress
+
+2. 기존 커스텀 위젯을 ShadCN으로 교체:
+   - standard_data_table.dart → ShadTable
+   - 모든 폼 입력 필드 → Shad 컴포넌트
+
+3. 통일된 디자인 토큰:
+   - 색상, 타이포그래피, 간격 표준화
+```
+
+### ⚡ **Phase 3: 기능 완성**
+```yaml
+1. Equipment History & Rent 시스템:
+   - 장비 라이프사이클 완전 추적
+   - 입고 → 출고 → 대여 → 반납 흐름
+
+2. Maintenance 시스템 (License 대체):
+   - Equipment History 기반 유지보수 관리
+   - 주기별 점검 스케줄링
+
+3. Company 계층 구조:
+   - 본사-지점 트리 뷰
+   - 계층별 권한 관리
+```

+# Superport ERP - Existing Implementation Analysis
+
+> **Date**: 2025-08-23  
+> **Status**: Complete - Ready for Migration Planning  
+> **Scope**: Comprehensive analysis of current implementation for new backend API migration
+
+## 📋 Executive Summary
+
+**Current Implementation Status**: The Superport ERP system is a **fully completed Flutter web application** based on Clean Architecture principles, but built against an **OLD backend API schema** that has been completely redesigned. The frontend requires **major architectural restructuring** to align with the new backend schema while migrating to ShadCN UI components.
+
+### Key Findings
+- **Completion Level**: ~90% functionally complete with the old API
+- **Architecture Gap**: 60% schema incompatibility with new backend
+- **UI Modernization Need**: 70% of components need ShadCN migration
+- **Missing Core Entities**: 5 critical entities not implemented (Vendors, Models, Equipment History, Rents, Maintenances)

+
+✻ Thinking…
+
+  사용자가 현재 프로젝트의 CLAUDE.md를 기준으로 claude_old.md를 통합하는 것에 대해 물어보고 있습니다. 
+
+  이전 대화 요약을 보면:
+  - Superport 프로젝트가 90% 완료되었지만 백엔드 API가 완전히 새로 개발되어서 프론트엔드를 완전히 재구성해야 하는 상황
+  - claude_old.md에는 이전 버전의 중요한 컨텍스트가 있을 것
+  - 현재 CLAUDE.md는 Smart Context Engineering 시스템에 맞춰 업데이트되었음
+
+  사용자는 line 175를 선택했는데, 이것은 아마도 현재 CLAUDE.md의 특정 부분을 가리키는 것 같습니다. 하지만 정확한 내용은 보이지 않네요.
+
+  claude_old.md를 통합하는 것에 대한 의견을 물어보는 것이므로, Dispatcher로 시작해서 분석해야 합니다.
+
+  먼저 claude_old.md 파일을 읽어보고 현재 CLAUDE.md와 비교하여 통합 전략을 제안해야 겠습니다.

-## 🔌 Unused Backend API Integration Plan
-
-### 현재 백엔드에 구현되었으나 프론트엔드에서 미사용 중인 API
-
-#### 1. `/overview/license-expiry` - 라이선스 만료 요약
-**용도**: 30일/60일/90일 내 만료 예정인 라이선스 요약 정보 제공
-**활용 계획**:
-- **위치**: Dashboard 화면 상단 알림 배너
-- **구현 방법**: 
-  - 만료 임박 라이선스 카운트를 배지로 표시
-  - 클릭 시 상세 라이선스 목록으로 이동
-  - 관리자/매니저 권한일 때만 표시
-- **예상 효과**: 라이선스 갱신 누락 방지, 사전 대응 가능
-
-#### 2. `/lookups` - 전체 조회 데이터
-**용도**: 시스템 전체 드롭다운/셀렉트 박스용 마스터 데이터 제공
-**활용 계획**:
-- **위치**: 앱 초기화 시 한 번 호출하여 캐싱
-- **구현 방법**:
-  - `LookupService` 생성하여 전역 상태 관리
-  - 장비 타입, 상태 코드, 제조사 목록 등 일괄 관리
-  - 각 화면에서 개별 API 호출 대신 캐시된 데이터 사용
-- **예상 효과**: API 호출 횟수 감소, 응답 속도 향상
-
-#### 3. `/lookups/type` - 타입별 조회 데이터
-**용도**: 특정 타입의 조회 데이터만 선택적으로 가져오기
-**활용 계획**:
-- **위치**: 대량 데이터 입력 화면 (장비 일괄 등록, Excel 임포트)
-- **구현 방법**:
-  - 필요한 타입만 선택적으로 로드
-  - 동적 폼 생성 시 활용
-  - 타입별 유효성 검증 규칙 적용
-- **예상 효과**: 메모리 사용량 최적화, 동적 UI 구성 가능
-
-#### 4. `/health` - 시스템 상태 체크
-**용도**: API 서버 상태 및 DB 연결 상태 확인
-**활용 계획**:
-- **위치**: 
-  - 로그인 화면 하단 (서버 상태 인디케이터)
-  - 관리자 대시보드 (시스템 모니터링 위젯)
-- **구현 방법**:
-  - 30초 간격 폴링으로 서버 상태 모니터링
-  - 연결 실패 시 자동 재시도 및 사용자 알림
-  - 서버 점검 시간 사전 공지 표시
-- **예상 효과**: 시스템 안정성 향상, 장애 조기 감지
-
-### 구현 우선순위
-1. **Phase 1 (1주차)**: `/overview/license-expiry` - 대시보드 통합

-## 🔑 Key Decisions
-
-### 2025-08-13 (Phase 4C 완료)
-- **Decision**: 전역 Lookups 시스템 적용 범위 결정 - Equipment 화면만 적용, 나머지 화면은 기존 방식 유지
-- **Reason**: 시스템 안정성 우선, 복잡성 대비 효용성 고려, Equipment 화면에서 성공적인 성과 확인
-- **Impact**: 
-  - ✅ Equipment 화면: 드롭다운 로딩 4회 → 0회, 즉시 로딩, 백엔드 100% 동기화
-  - ✅ Company, License, User, Warehouse Location: 검증된 기존 방식 유지
-  - ✅ 프로젝트 안정성 확보, 빌드 및 실행 테스트 통과
-  - ⚡ 개발 속도 향상: 검증된 패턴 유지로 버그 위험 최소화
-- **Implementation**: Equipment LookupsService 완성, 다른 화면 하드코딩 패턴 유지
-
-### 2025-08-13 (Phase 1-3)
-- **Decision**: 백엔드 API 스키마 기준 프론트엔드 전면 마이그레이션 및 전역 Lookups 시스템 구축
-- **Reason**: API 호환성 문제 해결, 성능 최적화, 데이터 일관성 확보
-- **Impact**: API 호환성 65% → 95% 향상, 드롭다운 로딩 속도 대폭 개선, 캐시 시스템 구축
-- **Implementation**: 
-  - API 응답 형식 표준화 (`success` → `status`)
-  - 페이지네이션 구조 현대화 (`meta.pagination` 중첩 구조)
-  - 소프트 딜리트 파라미터 통일 (`is_active`만 사용)
-  - ResponseMeta 클래스 신규 도입
-  - **전역 LookupsService 구축**: 30분 캐시, 백그라운드 갱신
-  - **Equipment 화면 완전 마이그레이션**: 하드코딩 → 백엔드 동기화
-
-### 2025-08-12
-- **Decision**: 소프트 딜리트 시스템 전면 구현 완료
-- **Reason**: 데이터 무결성 보장, 실수로 인한 데이터 손실 방지, 감사 추적 강화
-- **Impact**: Company, Equipment, License, Warehouse Location 모든 핵심 엔티티에서 논리 삭제 지원
-- **Implementation**: `deleted_at` 필드 추가, API 및 UI에서 삭제된 데이터 필터링 자동 처리
-
-### 2025-01-11
-- **Decision**: Clean Architecture 전면 적용 완료
-- **Reason**: 확장성, 테스트 용이성, 유지보수성 극대화
-- **Impact**: 모든 기능이 UseCase 패턴으로 재구현됨
-
-### 2025-01-07
-- **Decision**: Mock 서비스 제거, Real API 전용으로 전환
-- **Reason**: 개발 환경 단순화 및 실제 환경 테스트 강화
-
-### 2025-01-06
-- **Decision**: Provider 패턴 유지 (Riverpod 마이그레이션 보류)
-- **Reason**: 현재 구조가 안정적, 팀 학습 곡선 고려
-
-### 2024-12-20
-- **Decision**: Flutter Web 우선 개발
-- **Reason**: 빠른 배포와 크로스 플랫폼 지원

-## 🔴 Critical Issues (즉시 수정 필요)
-
-### 1. API 응답 형식 불일치
-
-**문제점**: 현재 코드와 API 스키마의 응답 구조가 완전히 다름
-
-#### 현재 코드 (잘못됨)
-```dart
-// lib/data/models/common/api_response.dart
-@Freezed(genericArgumentFactories: true)
-class ApiResponse<T> with _$ApiResponse<T> {
-  const factory ApiResponse({
-    required bool success,      // ❌ 잘못된 필드명
-    required String message,
-    T? data,
-    String? error,
-  }) = _ApiResponse<T>;
-}
-```
-
-#### API 스키마 (정답)
-```json
-{
-  "status": "success",         // ✅ 올바른 필드명
-  "message": "Operation completed successfully",
-  "data": { /* 실제 데이터 */ },
-  "meta": { /* 메타데이터 (페이지네이션 등) */ }
-}
-```
-
-**영향도**: 🔥 **극심함** - 모든 API 호출이 영향받음
-
-**수정 방법**:
-```dart
-// 수정된 ApiResponse
-@Freezed(genericArgumentFactories: true)
-class ApiResponse<T> with _$ApiResponse<T> {
-  const factory ApiResponse({
-    required String status,     // success/error
-    required String message,
-    T? data,
-    ResponseMeta? meta,         // 새로 추가
-  }) = _ApiResponse<T>;
-}
-
-// 새로운 메타 클래스
-@freezed
-class ResponseMeta with _$ResponseMeta {
-  const factory ResponseMeta({
-    PaginationMeta? pagination,
-  }) = _ResponseMeta;
-}
-```
-
-### 2. 페이지네이션 메타데이터 구조 불일치
-
-**문제점**: 페이지네이션 응답 구조가 API 스키마와 다름
-
-#### 현재 코드 응답 파싱
-```dart
-// lib/data/datasources/remote/company_remote_datasource.dart (line 88-104)
-final responseData = response.data;
-if (responseData['success'] == true && responseData['data'] != null) {  // ❌
-  final List<dynamic> dataList = responseData['data'];
-  final pagination = responseData['pagination'] ?? {};                  // ❌
-  
-  return PaginatedResponse<CompanyListDto>(
-    items: items,
-    page: pagination['page'] ?? page,
-    size: pagination['per_page'] ?? perPage,
-    totalElements: pagination['total'] ?? 0,                            // ❌ 필드명 불일치
-    totalPages: pagination['total_pages'] ?? 1,
-    // ...
-  );
-}
-```
-
-#### API 스키마 올바른 구조
-```json
-{
-  "status": "success",
-  "data": [...],
-  "meta": {
-    "pagination": {
-      "current_page": 1,
-      "per_page": 20,
-      "total": 150,
-      "total_pages": 8,
-      "has_next": true,
-      "has_prev": false
-    }
-  }
-}
-```
-
-**수정 방법**:
-```dart
-// 올바른 응답 파싱
-if (responseData['status'] == 'success' && responseData['data'] != null) {
-  final List<dynamic> dataList = responseData['data'];
-  final meta = responseData['meta']?['pagination'] ?? {};
-  
-  return PaginatedResponse<CompanyListDto>(
-    items: items,
-    page: meta['current_page'] ?? page,
-    size: meta['per_page'] ?? perPage,
-    totalElements: meta['total'] ?? 0,
-    totalPages: meta['total_pages'] ?? 1,
-    first: !(meta['has_prev'] ?? false),
-    last: !(meta['has_next'] ?? false),
-  );
-}
-```
-
-### 3. 소프트 딜리트 파라미터 불일치
-
-**문제점**: API는 `is_active` 파라미터를 요구하지만, 일부 코드에서는 `includeInactive` 사용
-
-#### 현재 코드 (혼재)
-```dart
-// lib/data/datasources/remote/company_remote_datasource.dart (line 72-78)
-Future<PaginatedResponse<CompanyListDto>> getCompanies({
-  // ...
-  bool? isActive,              // ✅ 올바름
-  bool includeInactive = false, // ❌ API 스키마에 없음
-}) async {
-  final queryParams = {
-    if (isActive != null) 'is_active': isActive,        // ✅ 올바름
-    'include_inactive': includeInactive,                // ❌ 제거해야 함
-  };
-}
-```
-
-#### API 스키마 정의
-```http
-GET /api/v1/companies?page=1&per_page=20&is_active=true
-```
-- `is_active=true`: 활성 데이터만
-- `is_active=false`: 삭제된 데이터만  
-- `is_active` 미지정: 모든 데이터
-
-**수정 방법**: `includeInactive` 파라미터 제거 및 `is_active`만 사용
-
----
-
-## 🟡 Major Issues (우선 수정 필요)
-
-### 4. JWT 토큰 구조 변경
-
-**문제점**: JWT 클레임 구조가 변경됨
-
-#### 기존 JWT (추정)
-```json
-{
-  "user_id": 1,
-  "username": "admin",
-  "role": "admin"
-}
-```
-
-#### 새로운 JWT 구조
-```json
-{
-  "sub": 1,           // user_id 대신 sub 사용
-  "username": "admin", 
-  "role": "admin",    // admin|manager|staff
-  "exp": 1700000000,
-  "iat": 1699999000
-}
-```
-
-**영향도**: AuthInterceptor 및 토큰 파싱 로직 수정 필요
-
-### 5. Equipment 상태 Enum 확장
-
-**문제점**: 장비 상태에 새로운 값 추가됨
-
-#### 현재 Equipment 상태
-```dart
-// lib/data/models/equipment/equipment_dto.dart
-enum EquipmentStatus {
-  @JsonValue('available') available,
-  @JsonValue('inuse') inuse,
-  @JsonValue('maintenance') maintenance,
-  // disposed가 누락됨
-}
-```
-
-#### API 스키마 Equipment 상태
-```dart
-enum EquipmentStatus {
-  available,   // 사용 가능
-  inuse,      // 사용 중  
-  maintenance, // 점검 중
-  disposed,   // 폐기 ⬅️ 새로 추가됨
-}
-```
-
-**수정 방법**: EquipmentStatus enum에 `disposed` 추가
-
-### 6. Company 모델 필드 누락
-
-**문제점**: Company DTO에 새로운 필드들이 누락됨
-
-#### 현재 CompanyResponse
-```dart
-@freezed
-class CompanyResponse with _$CompanyResponse {
-  const factory CompanyResponse({
-    // ... 기존 필드들
-    @JsonKey(name: 'is_partner') @Default(false) bool isPartner,
-    @JsonKey(name: 'is_customer') @Default(false) bool isCustomer,
-    // company_types 필드는 이미 있음
-  }) = _CompanyResponse;
-}
-```
-
-#### API 스키마에서 추가된 필드
-```dart
-// CreateCompanyRequest에 추가 필요
-@JsonKey(name: 'company_types') List<String>? companyTypes,  // ✅ 이미 있음
-@JsonKey(name: 'is_partner') bool? isPartner,              // ✅ 이미 있음  
-@JsonKey(name: 'is_customer') bool? isCustomer,            // ✅ 이미 있음
-```
-
-**상태**: ✅ 이미 대부분 구현됨 (양호)
-
----
-
-## 🟢 Minor Issues (점진적 개선)
-
-### 7. 에러 응답 처리 개선
-
-**문제점**: 에러 응답 구조가 표준화되지 않음
-
-#### 현재 에러 처리
-```dart
-// lib/data/datasources/remote/company_remote_datasource.dart
-catch (e, stackTrace) {
-  if (e is ApiException) rethrow;
-  throw ApiException(message: 'Error creating company: $e');
-}
-```
-
-#### API 스키마 표준 에러 형식
-```json
-{
-  "status": "error",
-  "message": "에러 메시지",
-  "error": {
-    "code": "VALIDATION_ERROR",
-    "details": [
-      {
-        "field": "name",
-        "message": "Company name is required"
-      }
-    ]
-  }
-}
-```
-
-**개선 방법**: 구조화된 에러 객체 생성
-
-### 8. 권한별 API 접근 제어
-
-**문제점**: 일부 화면에서 사용자 권한 확인 누락
-
-#### 권한 매트릭스 (API 스키마)
-| 역할 | 생성 | 조회 | 수정 | 삭제 |
-|------|------|------|------|------|
-| **Admin** | ✅ | ✅ | ✅ | ✅ |
-| **Manager** | ✅ | ✅ | ✅ | ✅ |
-| **Staff** | ⚠️ | ✅ | ⚠️ | ❌ |
-
-**현재 상태**: UI에서 권한 체크 미흡
-
-**개선 방법**: 
-```dart
-// 권한 기반 UI 제어
-if (currentUser.role == UserRole.staff) {
-  return SizedBox(); // 삭제 버튼 숨김
-}
-```
-
-### 9. 날짜/시간 형식 통일
-
-**문제점**: 날짜 필드의 타입과 형식이 일관되지 않음
-
-#### 현재 혼재된 형식
-```dart
-@JsonKey(name: 'purchase_date') String? purchaseDate,    // ❌ String
-@JsonKey(name: 'created_at') DateTime createdAt,         // ✅ DateTime
-```
-
-#### 권장 표준
-```dart
-@JsonKey(name: 'purchase_date') DateTime? purchaseDate,  // ✅ 모두 DateTime
-@JsonKey(name: 'created_at') DateTime createdAt,
-```
-
----
-
-## 🔵 Missing Features (신규 구현)
-
-### 10. Lookups API 미구현
-
-**상태**: ❌ 완전히 미구현
-
-#### API 스키마에서 제공
-```http
-GET /lookups          # 전체 마스터 데이터
-GET /lookups/type     # 타입별 마스터 데이터
-```
-
-#### 예상 활용도
-- 드롭다운 옵션 동적 로딩
-- 장비 카테고리, 제조사 목록
-- 상태 코드, 타입 코드 관리
-
-**구현 필요도**: 🟡 **Medium** (성능 최적화에 도움)
-
-### 11. Health Check API 미구현
-
-**상태**: ❌ 완전히 미구현
-
-#### API 스키마
-```http
-GET /health          # 서버 상태 체크
-```
-
-**활용 방안**:
-- 앱 시작 시 서버 연결 확인
-- 주기적 헬스체크 (30초 간격)
-- 네트워크 오류와 서버 오류 구분
-
-**구현 필요도**: 🟢 **Low** (운영 편의성)
-
-### 12. Overview API 부분 구현
-
-**상태**: ⚠️ **부분 구현**
-
-#### 구현된 API
-- ✅ `/overview/stats` - 대시보드 통계
-- ✅ `/overview/license-expiry` - 라이선스 만료 요약
-
-#### 미구현 API  
-- ❌ `/overview/recent-activities` - 최근 활동 내역
-- ❌ `/overview/equipment-status` - 장비 상태 분포
-
-**현재 처리 방식**: 404 에러를 받으면 빈 데이터 반환
-```dart
-// lib/data/datasources/remote/dashboard_remote_datasource.dart (line 61-65)
-if (e.response?.statusCode == 404) {
-  return Right([]);  // 빈 리스트 반환
-}
-```

+# License → Maintenance 시스템 전환 가이드
+
+## 📋 개요
+
+Superport ERP 시스템이 **License 관리 시스템**에서 **Maintenance 관리 시스템**으로 전환됩니다.
+이 문서는 시스템 변경사항과 새로운 사용 방법을 안내합니다.
+
+---
+
+## 🔄 주요 변경사항
+
+### 이전 (License 시스템)
+- **독립적인 License 관리**: Equipment와 별도로 라이선스 관리
+- **만료일 기반 관리**: 라이선스 만료일만 추적
+- **단순 비용 관리**: 라이선스 비용만 기록
+- **개별 관리**: Equipment와 라이선스를 각각 관리
+
+### 이후 (Maintenance 시스템)
+- **통합 관리**: Equipment History 기반 유지보수 관리
+- **주기적 관리**: 유지보수 주기와 다음 일정 자동 계산
+- **포괄적 관리**: 유지보수 이력, 비용, 일정 통합 관리
+- **자동화**: Equipment 입출고와 연동된 자동 추적
+
+---
+
+## 📊 화면별 변경사항
+
+### 1. 메뉴 구조 변경
+
+**이전:**
+```
+📁 라이선스 관리

-## 🧪 테스트 업데이트 가이드
-
-### 1. 단위 테스트 수정
-```dart
-// Repository 테스트 수정 예시
-group('CompanyRepository', () {
-  test('should return active companies when isActive is true', () async {
-    // Given
-    when(mockApiClient.getCompanies(
-      page: 1,
-      perPage: 20,
-      isActive: true,  // 추가된 파라미터 테스트
-    )).thenAnswer((_) async => mockActiveCompaniesResponse);
-
-    // When
-    final result = await repository.getCompanies(
-      page: 1,
-      perPage: 20,
-      isActive: true,
-    );
-
-    // Then
-    expect(result.isRight(), true);
-  });
-});
-```
-
-### 2. Widget 테스트 수정
-```dart
-testWidgets('should show restore button for deleted companies', (tester) async {
-  // Given
-  final deletedCompany = Company(id: 1, name: 'Test', isActive: false);
-  
-  // When
-  await tester.pumpWidget(CompanyListItem(company: deletedCompany));
-  
-  // Then
-  expect(find.text('복구'), findsOneWidget);
-  expect(find.byIcon(Icons.restore), findsOneWidget);
-});
-```
-
-### 3. 통합 테스트 수정
-```dart
-group('Company CRUD Integration', () {
-  test('soft delete should set is_active to false', () async {
-    // Create company
-    final company = await createTestCompany();
-    
-    // Delete (soft delete)
-    await apiClient.deleteCompany(company.id);
-    
-    // Verify soft delete
-    final companies = await apiClient.getCompanies(isActive: false);
-    expect(companies.data.any((c) => c.id == company.id), true);
-  });
-});
-```

-
-## 🚨 주의사항
-
-### 1. 데이터 마이그레이션
-- 기존 삭제된 데이터는 복구 불가능
-- 소프트 딜리트 전환 후에만 복구 가능
-
-### 2. 성능 영향
-- `is_active` 필터링으로 인한 쿼리 복잡도 증가
-- 인덱스 활용으로 성능 최적화 필요
-
-### 3. 권한 관리
-- 새로운 권한 체크 로직 확인 필요
-- Staff 권한 사용자의 기능 제한 확인
-
-### 4. 캐싱 전략
-- Lookups API 응답 캐싱 구현 권장
-- 대시보드 통계 캐싱으로 성능 개선
