+# Phase 1.2: 다건 BOM 기반 자동산출 API
+
+## 개요
+- **작업일**: 2026-01-02
+- **커밋**: `4e59bbf` feat: Phase 1.2 - 다건 BOM 기반 자동산출 API 구현
+- **목적**: React 견적등록 화면에서 여러 품목의 자동산출 일괄 요청
+
+## API 엔드포인트
+```
+POST /api/v1/quotes/calculate/bom/bulk
+```
+
+## 파일 목록
+
+### 생성된 파일
+| 파일 | 설명 |
+|------|------|
+| `app/Http/Requests/Quote/QuoteBomBulkCalculateRequest.php` | 다건 BOM 산출 FormRequest |
+| `api/docs/changes/20260102_1300_quote_bom_bulk_calculation.md` | 변경 내용 문서 |
+
+### 수정된 파일
+| 파일 | 설명 |
+|------|------|
+| `app/Services/Quote/QuoteCalculationService.php` | calculateBomBulk() 메서드 추가 |
+| `app/Http/Controllers/Api/V1/QuoteController.php` | calculateBomBulk 액션 추가 |
+| `routes/api.php` | /calculate/bom/bulk 라우트 추가 |
+| `app/Swagger/v1/QuoteApi.php` | 스키마 3개 + 엔드포인트 추가 |
+
+## React → API 필드 매핑
+
+| React 필드 (camelCase) | API 변수 (약어) | 설명 |
+|----------------------|----------------|------|
+| openWidth | W0 | 개구부 폭 (mm) |
+| openHeight | H0 | 개구부 높이 (mm) |
+| quantity | QTY | 수량 |
+| productCategory | PC | 제품 카테고리 |
+| guideRailType | GT | 가이드레일 타입 |
+| motorPower | MP | 모터 출력 |
+| controller | CT | 제어반 |
+| wingSize | WS | 날개 크기 |
+| inspectionFee | INSP | 검사비 |
+
+## 요청/응답 예시
+
+### 요청
+```json
+{
+  "items": [
+    {
+      "finished_goods_code": "SC-1000",
+      "openWidth": 3000,
+      "openHeight": 2500,
+      "quantity": 2
+    },
+    {
+      "finished_goods_code": "SC-2000",
+      "W0": 4000,
+      "H0": 3000,
+      "QTY": 1
+    }
+  ],
+  "debug": false
+}
+```
+
+### 응답
+```json
+{
+  "success": true,
+  "message": "견적 일괄 산출이 완료되었습니다.",
+  "data": {
+    "success": true,
+    "summary": {
+      "total_count": 2,
+      "success_count": 2,
+      "fail_count": 0,
+      "grand_total": 2500000
+    },
+    "items": [...]
+  }
+}
+```
+
+## 핵심 로직
+
+### QuoteBomBulkCalculateRequest::getInputItems()
+- React camelCase 필드명을 API 약어로 자동 변환
+- 양쪽 필드명 모두 지원 (하위 호환성)
+
+### QuoteCalculationService::calculateBomBulk()
+- 각 품목에 대해 calculateBom() 순회 호출
+- 성공/실패 카운트 집계
+- 개별 품목 실패가 전체에 영향 없음 (예외 처리)
+
+## 관련 문서
+- 계획 문서: `docs/plans/quote-calculation-api-plan.md`
+- Phase 1.1 문서: `docs/changes/20260102_quote_bom_calculation_api.md`
+- Phase 1.2 문서: `docs/changes/20260102_1300_quote_bom_bulk_calculation.md`
+
+## 다음 단계
+- React 프론트엔드에서 `/calculate/bom/bulk` API 연동
+- 실제 품목 데이터로 테스트
+- 저장 플로우 연결 (`POST /quotes` store API)
