+## 1. elink-online-common — StandardItem.java 버그 수정
+
+### 현상
+
+`StandardItem.toJson()` 직렬화 시 빈 `itemPart`가 반환되는 경우에도 쉼표 구분자와 함께 빈 문자열이 출력되어 잘못된 JSON이 생성됨.
+
+### 원인
+
+```java
+// 수정 전: itemPart 비어있어도 무조건 sb.append 호출
+if (ai > 0) sb.append(",");
+String key = keyIter.next();
+StandardItem item = group.get(key);
+if (showPretty) sb.append("\n");
+sb.append(item.toJson(showPretty, withBizData));
+ai++;
+```
+
+### 수정
+
+```java
+// 수정 후: itemPart가 비어있으면 구분자와 내용 모두 건너뜀
+String key = keyIter.next();
+StandardItem item = group.get(key);
+String itemPart = item.toJson(showPretty, withBizData);
+if (StringUtils.isNotEmpty(itemPart)) {

+## 3. StandardMessageCoordinatorDJB.java 수정
+
+### 3.1 `coordinateAfterCreateMessageByRule` — ERP 분기 추가
+
+기존: IP/MAC 설정 후 종료  
+수정: `corp_tlwn_virt_brcd=ERP` 일 때 HEAD 지점코드 및 EZDATA 전자금융공통영역 설정 추가
+
+```java
+// 네트워크 정보 수집 구조 변경 (setNetworkInfo → collectNetworkInfo 반환값 활용)
+String[] netInfo = collectNetworkInfo();
+String ipv4 = netInfo[0];
+String mac  = netInfo[1];
+
+// ERP 채널 분기
+String corpTlwn = StringUtils.trimToEmpty(standardMessage.findItemValue(HEAD_CORP_TLWN_VIRT_BRCD));
+if ("ERP".equals(corpTlwn)) {
+    setErpHeadFields(standardMessage);   // tx_cmgr_cd, mgmt_brcd, tx_brcd, insl_brcd, blng_brcd
+    setEzdataFields(standardMessage, ipv4, mac);  // EZDATA 6개 필드
+}
+```
+
+### 3.2 `coordinateBeforeResponse` — guid_prgs_no +1, dman_rspn_dvcd=R 추가
+
+```java
+// GUID 진행번호 +1
+mapper.nextGuidSeq(standardMessage);
+
+// 요청응답구분 = 응답(R)
+mapper.setSendRecvDivision(standardMessage, STDMessageKeys.SEND_RECV_CD_RECV);
+```
+
+### 3.3 `coordinateAfterRecvNonStdSyncResponse` — 정상 MSG 수정
+
+| 항목 | 수정 전 | 수정 후 |
+|------|--------|--------|
+| `outp_msg_cd` | `"000000000000"` | `"NCMM00001   "` |
+| `outp_msg_ctnt` | `"정상처리"` | `"정상처리되었습니다."` |
+| `msg_list_rowcnt` | `"00001"` | `"00000"` |
+| `msg_list` 행 생성 | 1건 생성 | 제거 (rowcnt=0) |
+
+### 3.4 `coordinateSetStandardMessageError` — MSG_LIST 항목 추가
+
+```java
+// 기존: outp_msg_cd, outp_msg_ctnt 만 설정
+// 추가:
+if (row.containsKey("outp_msg_desc")) row.get("outp_msg_desc").setValue(siteErrMsg);
+if (row.containsKey("err_occu_loct")) row.get("err_occu_loct").setValue(errCode);

+## 6-2. CSV 기본값 이관 리팩터링
+
+### 배경
+
+Coordinator에 하드코딩된 고정값들을 `standard-layout-djb.csv` 기본값(마지막 컬럼)으로 옮겨 코드 변경 없이 CSV 수정만으로 대응 가능하도록 개선.
+
+### standard-layout-djb.csv 변경 내용
+
+| 필드 | 변경 내용 |
+|------|----------|
+| `tx_cmgr_cd` | 기본값 `S004` 추가 |
+| `mgmt_brcd` | 기본값 `260` 추가 |
+| `tx_brcd` | 기본값 `260` 추가 |
+| `insl_brcd` | 기본값 `260` 추가 |
+| `blng_brcd` | 기본값 `260` 추가 |
+| `outp_msg_cd` (MAIN_MSG) | 기본값 `NCMM00001` 추가 |
+| `outp_msg_ctnt` (MAIN_MSG) | 기본값 `정상처리되었습니다.` 추가 |
+| `msg_list_rowcnt` | 기본값 `00000` → `0` 수정 (NUMBER 타입 선행 0 strip 반영) |
+
+### StandardMessageCoordinatorDJB.java 변경 내용
+
+- `setErpHeadFields()` 메서드 및 관련 상수 5개(`HEAD_TX_CMGR_CD` 등) 제거
+- `coordinateAfterCreateMessageByRule`: `setErpHeadFields()` 호출 제거
+- `coordinateAfterRecvNonStdSyncResponse`: `msg_dvcd`, `outp_atrb_cd`, `outp_msg_cd`, `outp_msg_ctnt`, `msg_list_rowcnt` 명시적 `setData` 호출 제거 (CSV 기본값으로 대체)
+
+### 테스트 수정
+
+- `StandardMessageSpecTest`: `비ERP_ERP_HEAD_필드_미설정` 테스트 제거
+  - `tx_cmgr_cd`가 CSV 기본값 `S004`로 항상 설정되므로 "비ERP에서 미설정" 조건이 무효화됨
+
+---
+
+## 6-3. EZDATA 조건 평가 리팩터링 — evaluateBlockCondition
+
+### 배경
+
+`coordinateAfterCreateMessageByRule`에서 EZDATA 활성화 조건을 `"ERP".equals(corpTlwn)`으로 하드코딩하고 있어, 조건 변경 시 Java 코드 수정이 필요했음.
+
+CSV 레이아웃에 이미 조건 정보가 존재함:
+```
+EZDATA,1,3,1,1,0,1,HEAD.corp_tlwn_virt_brcd,ERP,
+```
+
+### 해결: Coordinator에 refPath/refValue 평가 헬퍼 추가
+
+```java
+private boolean evaluateBlockCondition(StandardMessage standardMessage, StandardItem item) {
+    String refPath  = item.getRefPath();
+    String refValue = item.getRefValue();
+    if (StringUtils.isBlank(refPath) || StringUtils.isBlank(refValue)) return true;
+    String actualValue = StringUtils.trimToEmpty(standardMessage.findItemValue(refPath));
+    boolean negate = refValue.startsWith("!");
+    String compareValue = negate ? refValue.substring(1) : refValue;
+    boolean matched = matchesAny(compareValue, actualValue);
+    return negate ? !matched : matched;
+}
+
+private boolean matchesAny(String refValue, String actualValue) {
+    for (String v : refValue.split("\\|")) {
+        if (v.equals(actualValue)) return true;
+    }
+    return false;
+}
+```
+
+- `!` 접두사: NOT 조건 (`!S` → S가 아닌 경우)
+- `|` 구분자: OR 조건 (`NM|EM` → NM 또는 EM)
+
+### 변경 내용
+
+| 항목 | 수정 전 | 수정 후 |
+|------|--------|--------|
+| `ERP_CODE` 상수 | `"ERP"` 하드코딩 | 제거 |
+| `HEAD_CORP_TLWN_VIRT_BRCD` 상수 | `"HEAD.corp_tlwn_virt_brcd"` | 제거 |
+| EZDATA 조건 분기 | `if ("ERP".equals(corpTlwn))` | `if (evaluateBlockCondition(msg, ezdataItem))` |
+| `setEzdataFields()` 시그니처 | `(StandardMessage, String, String)` | `(StandardMessage, StandardItem, String, String)` |
+| `elfn_spr_fild` 설정값 | `"ERP"` 리터럴 | `ezdataItem.getRefValue()` (CSV에서 읽기) |
+
+---
+
+## 7. 주요 이슈 및 해결
+
+### ① NUMBER 타입 전체 zero strip (rowcnt 검증)
+
+- **현상**: `msg_list_rowcnt` (NUMBER, 5자리)에 `"00000"` 설정 후 `findItemValue()` → `""` (빈 문자열)
+- **원인**: `StandardItem.toTypeValue()`가 NUMBER 타입에서 선행 0 전부 제거 → 전체 0이면 빈 문자열
+- **해결**: 테스트에서 빈 문자열을 `"0"`으로 normalize 후 `Integer.parseInt()` 비교
+
+```java
+String normalized = (rowcnt == null || rowcnt.trim().isEmpty()) ? "0" : rowcnt.trim();
+assertEquals(0, Integer.parseInt(normalized), "정상 응답 msg_list_rowcnt는 0이어야 함");
+```
+
+### ② EZDATA 조건부 직렬화 — MSG 블록과 다른 동작
+
+- **현상**: 비ERP 요청(corp_tlwn_virt_brcd 미설정) 직렬화 시에도 EZDATA 블록이 기본값으로 포함됨
+- **원인**: MSG 블록은 `dman_rspn_dvcd=!S` 조건으로 파싱 시 hidden 처리되지만, EZDATA는 해당 조건이 직렬화 시 재평가되지 않고 기본값으로 렌더링됨
+- **해결**: 비ERP 테스트에서 "EZDATA 없음" 대신 "ERP 전용 필드(usr_no, rgsr_id)가 빈 값" 검증으로 전환
+
+### ③ `setNetworkInfo` 리팩터링 — EZDATA 재사용
+
+- **배경**: 기존 `setNetworkInfo(StandardMessage)` private 메서드는 IP/MAC을 수집·설정만 하고 반환값 없음
+- **문제**: EZDATA 설정 시 IP/MAC을 다시 수집해야 하므로 중복 발생
+- **해결**: `collectNetworkInfo()` 로 분리 (`String[]` 반환), `coordinateAfterCreateMessageByRule` 에서 한 번만 수집 후 HEAD와 EZDATA에 공유
+
+---
+
+## 8. 향후 작업
+
+- [ ] `elfn_bnkn_dvcd` 기본값 CSV 수정 (`01` → `10`) — 비ERP 요청의 기본값 정합성 확인
+- [ ] `svr_tx_seqno` 10자리 검증 — Unix timestamp가 10자리인지 2038년 이후 11자리 여부 확인
+- [ ] `outp_msg_cd` 정상코드 `"NCMM00001"` — DJBank 메시지 코드 체계 확인 후 확정
+- [ ] ERP 채널 실서버 통합 테스트 — EZDATA 전자금융공통영역 정상 전달 검증
