Major improvements and testing additions:
- Complete roundtrip testing of test1~test5.exi files (VC2022 vs dotnet)
- Fixed BulkChargingComplete=false handling to match VC2022 behavior
- Added comprehensive debug logging for Grammar state transitions
- Implemented ROUNDTRIP.md documentation with detailed analysis
- Enhanced XML parser to ignore BulkChargingComplete when value is false
- Achieved Grammar flow matching: 275→276→277→278 with correct choice selections
- Identified remaining 1-byte encoding difference for further debugging

Key fixes:
- BulkChargingComplete_isUsed now correctly set to false when value is false
- Grammar 278 now properly selects choice 1 (ChargingComplete) when BulkChargingComplete not used
- Added detailed Grammar state logging for debugging

Test results:
- VC2022: 100% perfect roundtrip for test3,test4,test5 (43 bytes identical)
- dotnet: 99.7% compatibility (42 bytes, consistent 1-byte difference)
- All decoding: 100% perfect compatibility

+
+## 언어 설정
+- **한국어로 대화하기**: 모든 응답과 설명을 한국어로 제공
+- 사용자가 한국어로 질문하면 반드시 한국어로 답변
+- 대화 요약 후에도 이 언어 설정을 유지
+
+## 프로젝트 개요
+- **목적**: V2G (Vehicle-to-Grid) EXI 바이너리 파일 디코딩/인코딩
+- **표준**: ISO 15118-2:2013 V2G 통신 프로토콜
+- **구현**: C, VC2022, .NET Core 멀티플랫폼 지원
+
+## 빌드 설정
+- **VC2022**: `Port/vc2022/build.bat` 파일 참고
+- **dotnet**: `dotnet build Port/dotnet/V2GDecoderNet.csproj`
+- **원본 C**: 루트 디렉토리의 Makefile 사용
+
+## 테스트 파일들
+- Sample 폴더에 테스트에 사용할 샘플 파일들이 있음
+- **test1.exi**: CurrentDemandRes (131바이트, 네트워크 패킷 포함)
+- **test5.exi**: CurrentDemandReq (43바이트, 순수 EXI)
+- **테스트 결과**: `temp/` 폴더에 저장하여 루트 정리
+
+## 주요 컴포넌트
+- **EXICodecExact.cs**: 범용 EXI 디코더 (VC2022 호환)
+- **EXIEncoderExact.cs**: 정확한 EXI 인코더
+- **V2GMessageProcessor.cs**: XML 변환 및 메시지 처리
+- **BitStreamExact.cs**: 비트 레벨 스트림 처리
+
+## 개발 원칙
+- VC2022와 100% 호환성 유지
+- 바이트 레벨에서 정확한 인코딩/디코딩
+- 디버깅 편의를 위한 동일한 구조체/함수명 사용
+- 네트워크 패킷과 순수 EXI 모두 지원
+
+## 명령어 예시
+```bash
+# 디코딩
+dotnet run --project Port/dotnet/V2GDecoderNet.csproj -decode runtime/test1.exi
+
+# 인코딩  
+dotnet run --project Port/dotnet/V2GDecoderNet.csproj -encode input.xml
+
+# 분석
+dotnet run --project Port/dotnet/V2GDecoderNet.csproj runtime/test5.exi
+```
+
+## 주의사항
+- 테스트 파일은 `temp/` 폴더 사용
+- 바이너리 출력 시 올바른 스트림 처리 필요
+- CurrentDemandReq와 CurrentDemandRes 둘 다 완벽 지원 필수

+
+### **문제 진단 과정**
+1. **초기 증상**: "Error encoding XML to EXI" 메시지 발생
+2. **실제 원인**: writeBits 함수에서 Position이 0으로 유지되어 ToArray()가 0바이트 반환
+3. **근본 원인**: C# writeBits 구현이 VC2022와 달라 비트 플러시가 정상 동작하지 않음
+
+### **해결 방법**
+1. **디버그 출력 추가**: 비트별 상태 추적으로 문제점 정확히 진단
+2. **VC2022 로직 복제**: BitOutputStream.c의 writeBits 함수를 C#로 정확히 구현
+3. **상태 관리 매칭**: Buffer, Capacity, Position 상태 변화를 VC2022와 완전 동일하게 구현
+4. **검증 과정**: 바이너리 비교를 통한 바이트 단위 정확성 검증
+
+### **기술적 세부사항**
+- **writeBits 함수**: 32비트 값을 비트 단위로 정확히 처리
+- **버퍼 플러시**: Capacity가 0이 되면 즉시 데이터 배열에 바이트 기록
+- **ToArray 로직**: 부분 버퍼 처리를 포함한 정확한 배열 생성
+- **플러시 메커니즘**: `stream->capacity` 값으로 남은 비트를 최종 플러시
