+## 2025-11-20 (수) - ItemMaster API Swagger 문서 작성
+
+### 주요 작업
+- ItemMaster 전체 API (32개 엔드포인트) Swagger 문서화 완료
+- OpenAPI 3.0 표준 준수
+- 기존 SAM Swagger 패턴 따름
+
+### 추가된 파일
+
+1. **app/Swagger/v1/ItemMasterApi.php** (~900 lines)
+   - Tag 정의: ItemMaster 리소스
+   - Model Schemas (8개): ItemPage, ItemSection, ItemField, ItemBomItem, SectionTemplate, ItemMasterField, CustomTab, UnitOption
+   - Request Schemas (12개): 각 리소스별 Store/Update + ReorderRequest
+   - Response Schema: ItemMasterInitResponse (nested arrays)
+   - 32개 엔드포인트 전체 문서화
+
+### Swagger 문서 구조
+
+**Model Schemas**:
+- ItemPage (id, page_name, item_type, sections[])
+- ItemSection (id, section_name, item_type, order_no, fields[])
+- ItemField (id, field_key, label, type, options[], validation_rules)
+- ItemBomItem (id, item_page_id, material_code, part_code, quantity, waste_rate)
+- SectionTemplate (id, name, description, fields[])
+- ItemMasterField (id, field_key, label, type, category)
+- CustomTab (id, label, icon, is_default, order_no)
+- UnitOption (id, label, value)
+
+**Request Schemas**:
+- Store/Update 요청 스키마 (각 리소스별)
+- ReorderRequest (items 배열)
+
+**Endpoint Documentation** (32개):
+- Init (1): 초기 데이터 로드
+- ItemPage (5): CRUD + reorder
+- ItemSection (6): CRUD + reorder + restore
+- ItemField (5): CRUD + reorder
+- ItemBomItem (5): CRUD + reorder
+- SectionTemplate (5): CRUD + reorder
+- ItemMasterField (3): index, store, delete
+- CustomTab (5): CRUD + reorder
+- UnitOption (3): index, store, delete
+
+### 작업 내용
+
+**1단계: 분석**
+- 기존 CategoryApi.php 구조 분석
+- ItemMaster 모델 구조 파악 (8개 모델)
+- 엔드포인트 전체 목록 정리 (32개)
+
+**2단계: Swagger 파일 생성**
+- Model Schema 정의 (nullable, type, example 포함)
+- Request/Response Schema 정의
+- 전체 엔드포인트 @OA annotation 작성
+- Security 설정 (ApiKeyAuth + BearerAuth)
+
+**3단계: 검증**
+- `php artisan l5-swagger:generate` 실행 성공
+- `./vendor/bin/pint` 코드 포맷팅 (1개 스타일 이슈 수정)
+- 라우트 목록 확인 (32개 엔드포인트 정상)
+
+### 검증 결과
+
+**Swagger 생성**:
+```bash
+php artisan l5-swagger:generate
+# 결과: Regenerating docs v1 성공
+```
+
+**코드 포맷팅**:
+```bash
+./vendor/bin/pint app/Swagger/v1/ItemMasterApi.php
+# 결과: 1 file, 1 style issue fixed
+```
+
+**라우트 확인**:
+```bash
+php artisan route:list --path=item-master | grep -c "item-master"
+# 결과: 32개 엔드포인트
+```
+
+### 다음 단계
+
+**남은 작업**:
+- API 테스트 케이스 작성
+- Frontend 연동 (React ItemMaster 화면)
+
+### Git 커밋
+- 커밋 예정: Swagger 문서 추가
+
+---
+
 ## 2025-11-20 (수) - ItemMaster Phase 3 API 구현 (부가 기능)
