+**역할 호환 어댑터를 경유한 실제 격리 OpenSQL·OpenProxy에서 4회차가 통과했습니다.** 최초 요청 192개 중 174개는 204였고, Primary 상실 때의 503 18개는 같은 키 재시도로 모두 확정했습니다. 최초 204 키 174개가 모두 보존됐으며 최종 요청 키는 192개, 회수 대상 권한 행과 최종 인가 허용은 0개입니다.
+
+> **원본 OpenProxy 그대로는 두 동기 모드 모두 시작에 실패합니다.** `sync_standby`와 `quorum_standby` parser 오류를 실제 관측했으며 [호환 어댑터와 원본 실패 기록](../patroni-role-compatibility-20261017/README.md)에 분리했습니다. 아래 표는 어댑터 경유 결과이며 공급사 공식 지원이나 공개 배포 완료를 뜻하지 않습니다.

+- 각 회차는 합성 권한 48개·동시성 2이며 동일 애플리케이션/시험 코드 `bb3c73521155a64e9675a28a32c9f673f9a47e0f`를 사용했습니다.
+- 네 회차 모두 strict=true, synchronous_node_count=1, on. 최초 Primary·호스트·스키마·데이터량을 같게 초기화했습니다. 지정형은 실제 sync 후보 1대, quorum은 실제 ANY 1 후보 2대를 SQL로 확인했습니다.
+- Primary 자동 승격 관측은 지정형 **20.385초**, quorum **18.695초**입니다. 쓰기 재개는 각각 **26.067초**, **25.902초**입니다. 표본 1회씩이며 이 차이로 성능 우위를 일반화하지 않습니다.
+- 장애 중 204 뒤 별도 인가 확인이 불가능한 경우는 Primary 회차마다 **2건**이었습니다. 허용으로 추정하지 않았으며 별도로 집계했습니다. `forbidden_content` 원시 카운터는 **최종 인가가 true인 횟수**이고, GCP 네 조회 API의 실제 본문 반환량을 계측한 값이 아닙니다.
+- 503은 롤백 확정으로 표현하지 않았습니다. 같은 요청 키의 WAL 재주장과 독립 JDBC 키 감사로 최종 상태를 대조했습니다.

+## 준비 실패와 재시험
+
+| 실행 | 관측 | 처리 |
+| --- | --- | --- |
+| preflight JDBC 01–04 | native DB 경로는 읽혔으나 원본 Proxy 연결 실패 | 로그 폴더 권한 문제를 분리한 뒤 native 역할 parser 결함 확인 |
+| [preflight JDBC 05](preflight-jdbc-run05.log) | 어댑터 경유 두 Proxy에서 ANY 1·Primary·streaming 2대 확인 | 본 비교로 진행 |
+| [designated-standby-run01](designated-standby-run01/control.jsonl) | streaming 1대라 사전 기준 실패 | 부하·장애 주입 미실행, SQL readiness 대기 보완 |
+| [designated-standby-run02](designated-standby-run02/control.jsonl) | 강제 종료 후 시험 socket 잠금이 남아 재기동 실패 | 정지된 시험 컨테이너의 전용 socket만 정리 |
+| [designated-standby-run03](designated-standby-run03/app.log) | WAN 스키마 초기화·fixture 준비가 180초 준비 제한 초과 | 장애 주입 미실행. 뒤늦게 시작된 부분 응답 10개는 모두 204였으나 시험을 중단했으며 최종 4회 집계에서 제외. 사전 배치 준비로 분리 |
+| [designated-standby-run04](designated-standby-run04/app.log) | 48개 204 뒤 검증용 autocommit 조회가 standby에 도착해 Primary 단언 실패 | 최종 대조도 read-write Transaction으로 수정. [실패 회차 키 감사](designated-standby-run04/post-failure-key-audit.log)는 통과 판정에 재사용하지 않음 |
+| designated-standby-run05 | 수정된 동일 시험과 독립 키 감사 통과 | 최종 집계에 사용 |
+
+추가 준비 과정에는 기존 RSA SSH 인증 실패, 임시 만료 키 사용, Docker commit 출력 형식/시간 제한, 읽기 전용 패키지의 로그 경로 준비 문제가 있었습니다. 초기 이미지 캡처 1회에는 Docker 기본 pause가 사용됐고 이후에는 pause=false를 적용했습니다. 공개 HTTP 영향은 계측하지 않았습니다. 공개 DB 설정 hash는 모든 제어 단계에서 일치했습니다.
+
+## 재실행
+
+1. 정식 사용 가능한 기존 라이선스 호스트에 별도 시험 데이터·DCS namespace·포트로 3노드를 준비합니다. 공급사 파일·라이선스·실제 인프라 설정은 이 저장소에 포함하지 않습니다.
+2. `patroni_role_compatibility.py`를 시험 scope와 private IPv4에만 연결합니다. 시험 OpenProxy의 Patroni 조회 포트는 해당 어댑터를 가리켜야 합니다.
+3. 전용 루프백 JDBC URL·별도 migration URL·비공개 접속 설정과 `PERMISSION_HA_RUN_DIR`, `PERMISSION_HA_MODE`, `PERMISSION_HA_SCENARIO`를 준비하고 `./backend/gradlew -p backend permissionHaTest`를 실행합니다. Task는 전용 loopback Proxy URL만 허용합니다.
+4. 실행 디렉터리의 `ready` 뒤에 시험 컨테이너만 중단하고, 실제 승격·재가입 관측 뒤 `fault.done`을 기록합니다. 제어 시각은 별도 JSONL에 남겨야 합니다.
+5. 같은 JDBC 드라이버로 `PermissionLedgerReconcile.java`를 실행해 실제 외부 요청 키를 다시 대조합니다. 호스트 접속·자원 생성 제어 프로필은 비공개로 분리했습니다.
+
+## 수동 검토 뒤 실행 제한 보완
+
+- Flyway·fixture 준비 주소도 전용 loopback 포트만 허용하고, 지원하는 모드·시나리오를 제한했습니다. 이전 응답 원장이나 완료 표식이 있는 디렉터리는 재사용하지 않습니다.
+- [migration 주소 차단](guard-migration-run01.jsonl), [이전 원장 보호](guard-ledger-run01.jsonl) 두 목적별 검사에서 예상 사전 조건 오류로 실행이 중단되고 원장이 변하지 않았습니다. 이는 의도한 exit 1을 통과 기준으로 한 검사이며 DB 장애 회차 실패가 아닙니다.
+- 이 사전 조건·integration 태그 보완 후 GCP 4회차를 다시 실행하지 않았습니다. 위 표는 명시한 `bb3c735` 실행 그대로입니다.
+
+## 운영 판단과 검증 한계
+
+- 이번 조건에서는 quorum의 뚜렷한 우위를 관측하지 못했습니다. 한 Standby 상실은 두 모드 모두 48개 204를 유지했고 Primary 상실은 두 모드 모두 9개 503과 같은 키 재시도로 수렴했습니다.
+- 원본 OpenProxy 역할 호환 문제가 있으므로 **현재 공개 클러스터의 동기/quorum 전환은 보류**합니다. 동기 확정 기능 기본값 false이며 운영 설정·배포를 이 시험으로 바꾸지 않았습니다.
+- 실제 OpenSQL 자동 승격을 시험했지만 후보 지정 수동 전환, 네트워크 분할, 임의 복제 지연, 동기 후보 전체 상실은 이 GCP 비교 범위 밖입니다. 사전 패키지 읽기에서 확인한 #3310 핵심 패치 부재를 해결했다고 주장하지 않습니다.
+- 로컬 시험의 COMMIT 경고·응답 유실 모델과 이번 GCP Primary 중단을 구분합니다. GCP에서 COMMIT 후 HTTP 응답만 차단한 별도 회차는 실행하지 않았습니다.
+- 로컬에서는 상세·본문·파일·새 검색 MVC 응답을 검증했습니다. GCP에서는 회수·최종 인가·원장 대조를 검증했습니다. 실제 모델·검색 품질·공개 로그인·GCS는 포함하지 않았습니다.
+- 기존 VM의 물리 자원을 공유하고 IAP 지연이 포함됐습니다. 전역 RPO=0·공개 서비스 전체 RTO·성능 SLA·공급사 공식 지원으로 확장하지 않습니다.
+- 시간 정의 보완은 원시 원장에 동일 규칙을 적용한 사후 집계이며 원시 `measurement.json`의 fault-requested 기준 값도 보존했습니다.
+
+## 정리 확인
+
+[정리 원장](cleanup.jsonl)에 실제 작업 결과를 시간순으로 보존했습니다.
+
+- 격리 GCP 컨테이너 3개·전용 데이터 경로 3개·확인된 시험 이미지 3개를 제거했습니다. 전용 DCS 키는 0개입니다.
+- 로컬 fixture 컨테이너 3개와 전용 Docker 네트워크 1개를 제거했습니다.
+- 30분 임시 OS Login 키는 이미 만료·부재 상태였고 일치하는 키 0개를 다시 확인했습니다. 로컬 개인키·비밀 파일을 제거하고 전용 SSH 제어 연결 3개를 종료했습니다. 기존 개인키·터널은 유지했습니다.
+- 공개 클러스터는 최종 조회에서 leader 1대·streaming replica 2대, 기존 비동기 설정으로 확인했습니다. 원본 설정 hash도 3대 모두 같았습니다. 기존 VM은 정지하지 않았습니다.
+- 생성 경위가 확정되지 않은 이전 이미지 캐시는 broad prune하지 않았습니다. 따라서 호스트의 모든 이미지 캐시가 0개라고 주장하지 않습니다.

+# 격리 동기 정책 비교의 판정·계측 경계
+
+## 사전 조건
+
+- 실제 OpenSQL PostgreSQL 17.8·Patroni 4.0.5, 원본 OpenProxy와 동일 역할 호환 어댑터.
+- 지정형/Quorum 모두 strict=true, synchronous_node_count=1, 쓰기 synchronous_commit=on.
+- 각 회차의 데이터·DCS 시험 namespace를 초기화하고 동일 호스트를 초기 Primary로 시작한다. Standby 두 대가 streaming인지 실제 SQL로 확인한다.
+- 스키마와 Flyway 이력만 동일하게 사전 적재한다. 문서 데이터가 없는 스키마 snapshot SHA-256: `6c730ecef5fbb9587e57f325f18421b2f663ae057eb42078fb29446bdc17d219`.
+- 합성 사용자·문서·READ 권한 48개를 직접 Primary에서 배치로 준비한다. 준비 시간은 장애 지연에 포함하지 않는다.
+- 측정 JVM·Controller·JPA·Hikari·부하는 동일하다. 동시성 2, 표본 48개, 요청마다 독립 UUID. 모델·검색 품질·공개 로그인·GCS는 포함하지 않는다.
+
+## 장애
+
+- 첫 4개 응답 뒤 지정 동기 후보인 시험 node2를 강제 종료하고 약 8초 대기 후 시작한다.
+- 별도 회차에서는 시험 Primary node1을 강제 종료해 **후보를 지정하지 않은 자동 승격**을 관찰한다. 과거 #3310의 후보 지정 수동 전환 경로와 구분한다.
+- 실제 종료 완료·새 Primary 관측·재가입 시각은 외부 제어 원장에 KST로 기록한다.
+
+## 통과 기준
+
+- 최초 204를 받은 요청 키가 모두 현재 Primary에 남아야 한다.
+- 결과 불명은 같은 키 WAL 재주장으로 해소하고, 최종 요청 키 48개·권한 행 0개로 수렴해야 한다.
+- 응답 뒤 최종 인가에서 접근 허용 0건. 권위 조회 실패는 허용으로 집계하지 않고 별도 건수로 보존한다.
+- 최종 대조도 read-write Transaction으로 현재 Primary에 고정한다. 추가 독립 JDBC 감사로 실제 외부 요청 키들을 대조한다.
+
+## 시간 해석
+
+- `max_initial_204_gap_seconds`: 계속 제공한 최초 요청 48개 중 연속 204 응답 사이의 최대 간격이다. 준비·의도적 재시도 대기 구간은 제외한다.
+- 쓰기 재개: Standby 장애는 종료 확인 이후 첫 204, Primary 장애는 새 Primary 관측 이후 첫 204를 사용한다. 시작은 실제 종료 확인 시각이다.
+- 지연 p50/p95는 최초 48개 응답 전체(불명 포함)의 MVC 호출 시간을 정렬해 nearest-rank로 계산한다.
+- Hikari active/pending 최대값은 100 ms 간격 표본이다. 순간 최대를 놓칠 수 있다.
+- 이 수치는 로컬 JVM→IAP→격리 OpenProxy·DB 경로이며 공개 서비스 전체 RTO·성능 SLA가 아니다. 기존 라이선스 VM의 물리 자원을 공유하므로 성능 우열을 일반화하지 않는다.
+
+## 원본과 호환 계층
+
+원본 OpenProxy는 native sync_standby와 quorum_standby를 모두 거부했다. 성공한 비교는 역할 어댑터 경유 결과이며, 원본 공급사 공식 동기/quorum 지원으로 표현하지 않는다.
