docs: B-1 — Redis moves the session and leaves the tokens behind

Adding Spring Session Redis grows the context by 81 beans and swaps sessionRepository for RedisSessionRepository, while authorizedClientService stays InMemoryOAuth2AuthorizedClientService. The user then reads as logged in with principal labuser while accessTokenStoredOnServer is false, which is worse than being logged out.

Redis holds only the security context, serialized with Java native serialization, and the refresh token is not there to encrypt in the first place. Three problems on the way: Kubernetes service links overwrote REDIS_PORT with a tcp:// URL, the tests tried to reach Redis, and the resource server was never deployed so a DNS failure looked like a token failure.

+# A-2 — PostgreSQL 정지 증거

+2026-09-04 11:56–11:58 KST · Keycloak 26.7.0
+해설: [`docs/experiment-a2-database-loss.md`](../../experiment-a2-database-loss.md)
+
+| 파일 | 무엇을 보여주는가 |
+|---|---|
+| `01-baseline.txt` | 정지 전 — 양쪽 Ready, `cluster_size=2` |
+| `02-setup-sessions.txt` | 양쪽 노드에 세션 하나씩. 캐시는 각자 노드에만 |
+| `03-four-paths.txt` | **네 경로 전부 `500`.** 캐시를 가진 노드도 실패 — refresh 는 쓰기다 |
+| `04-health-and-service.txt` | **전면 장애 증거** — Ready 파드 0개, `ready 주소=[]`, 외부 **503**, `database connections: DOWN`. JWKS·.well-known 은 `200` |
+| `05-recovery.txt` | **`up=1` 인 채로 503.** DB 복귀 15초 후 재시작 0회로 자동 회복, 세션 5건 생존 |
+| `a2-up-stayed-1-during-outage.png` | Grafana — `up{job="keycloak"}` 이 전면 장애 내내 **1에 평평** |
+
+## 핵심 세 줄
+
+1. **DB 는 단일 장애점이다.** Keycloak 을 몇 대로 늘려도 같이 죽는다 — Ready 파드 0개, 외부 503.
+2. **캐시는 읽기를 대신할 뿐 쓰기를 못 한다.** refresh 는 `UPDATE LAST_SESSION_REFRESH` 를 하므로 캐시가 있어도 실패한다.
+3. **`up` 은 이 장애를 못 잡는다.** 알림은 readiness 와 외부 응답 코드에 걸어야 한다.

+
+2026-09-04 12:00–12:05 KST · Keycloak 26.7.0 / PostgreSQL 16
+해설: [`docs/experiment-a3-database-crash.md`](../../experiment-a3-database-crash.md)
+
+| 파일 | 무엇을 보여주는가 |
+|---|---|
+| `01-crash-injection.txt` | 첫 시도 실패 — 파드 안 백그라운드 루프가 `exec` 종료와 함께 죽어 0건 수집 |
+| `02-design-check.txt` | **핵심 설계 확인** — 로그인 트랜잭션도 `SET LOCAL synchronous_commit TO OFF` 로 커밋한다 |
+| `03-loss-measurement.txt` | `--grace-period=0 --force` 주입 |
+| `04-comparison.txt` | **유실 0건** — 그러나 crash recovery 가 안 돌았다. 죽인 적이 없는 것 |
+| `05-true-crash.txt` | `kill -9 1` 시도 — **컨테이너 안에서 PID 1 은 SIGKILL 을 무시한다** |
+| `06-backend-kill-crash.txt` | **성공한 주입** — 백엔드에 SIGKILL → `not properly shut down` / `redo starts` / `redo done` |
+| `07-loss-result.txt` | **결과: 153건 중 4건 유실.** 토큰은 발급됐는데 세션 행이 없는 sid 목록 |
+
+## 핵심 세 줄
+
+1. **로그인도 비동기 커밋이다.** refresh 시각뿐 아니라 **로그인 자체**가 사라질 수 있다.
+2. **153건 중 4건(약 2.6%) 유실** — 초당 19건 기준 마지막 0.2초 분량, `wal_writer_delay` 기본값과 일치.
+3. **주입을 세 번 시도해 세 번째에 성공했다.** 앞의 둘은 "손실 0"으로 보였지만 실제로는 크래시가 아니었다.

+1. **쿠버네티스는 40초 동안 노드가 살아 있다고 말한다.** 사용자는 이미 장애를 겪는 중이다.
+2. **죽은 파드의 상태는 화석이다.** `ready=true` 인 파드가 꺼진 기계 위에 있다.
+3. **StatefulSet 은 대체 파드를 만들지 않고, PVC 는 재배치를 막는다.** 사람이 개입해야 한다.
+4. **컨트롤 플레인 상실 ≠ 워크로드 상실.** 컨테이너는 계속 돌고, 들어갈 문만 사라진다.

+2. **단방향 차단으로는 못 가른다.** JGroups 가 열린 방향으로 재연결한다 (자가 치유).
+3. **양방향이면 갈라진다** — `coord=t` 가 둘.
+4. **그래도 전면 장애가 아니다.** 코디네이터 쪽만 UP 을 유지해 서비스가 계속된다 — A-1 의 열린 질문에 대한 답.

+# A-6 — 지연 주입 증거
+
+2026-09-04 13:10–13:35 KST
+해설: [`docs/experiment-a6-latency-injection.md`](../../experiment-a6-latency-injection.md)
+
+| 파일 | 무엇을 보여주는가 |
+|---|---|
+| `01-baseline.txt` | 배치 설명(A/B 가 되는 이유), `agroal_*` 지표 목록, **기준선 70ms / 66ms** |
+| `02-delay-injected.txt` | 첫 시도 실패 — **`Cannot find device "eth0"`** (Debian 은 `enp1s0`) |
+| `03-flannel-injection.txt` | **성공** — `flannel.1` 에 걸어야 파드 IP 가 보인다. netem `Sent 150 pkt` 로 검증. **k0=41ms vs k1=1872ms** |
+| `04-pool-under-load.txt` | 동시 20건 — 응답이 1.9초에서 **22.2초**까지 계단. `blocking_time_max=20000ms`, `max_used_count=19`, **readiness 프로브 타임아웃** |
+| `05-recovery.txt` | 해제 즉시 43ms / 51ms 회복. **낙관적 락 충돌 0건**(예측 빗나감) |
+| `a6-connection-pool-blocking.png` | Grafana — `agroal_blocking_time_max_milliseconds` |
+
+## 핵심 네 줄
+
+1. **200ms 가 1,872ms 가 된다.** 로그인 트랜잭션의 왕복이 9번이라 지연이 곱해진다.
+2. **동시 부하에서 22초까지 늘어난다.** 커넥션 풀 큐잉으로 한 번 더 곱해진다.
+3. **헬스체크도 같은 줄에 선다** — 프로브가 타임아웃되어 노드가 로드밸런서에서 빠지고, 남은 노드로 부하가 몰린다.
+4. **낙관적 락 충돌은 없었다.** 로그인은 새 행을 만들 뿐 같은 행을 다투지 않는다 — B-3 의 영역.
