DongHyeonkaandClaude Opus 5 b2963105a8 docs(keycloak-session-store): import the session-storage lab as a new project
The keycloak project ended with four open questions that design could not
settle. A two-VM lab was built to answer them by measurement, and this is
that material: 26 experiments, 125 raw command outputs, 22 browser captures.

Follows the import procedure in README.md.

  source/     the originating repository verbatim — 78 documents, 28 SVGs,
              8 manifests, plus .source-revision recording the commit
  final/      the SSOT
    document.md   729 lines written from the 29 experiment documents, not
                  concatenated: what was predicted, what was measured, and
                  where the measurement itself was wrong
    evidence/raw    125 outputs, flattened to <experiment>__<file> because
                    the originals collided (01-baseline.txt appeared three
                    times) and the audit only globs the top level
    evidence/meta   one per raw file; command and exitCode are null and the
                    README says why rather than inventing them
    evidence/browser  22 captures
    assets/       three diagrams through techviz
    .techviz/     their VizSpecs

A separate project rather than an addition to keycloak: the B-layer answers
that project's four questions, but the A, C and D layers are about cluster
failure, SSO and operations, and one document.md should hold one subject.
The four question records there can point here through 관계.

Recorded rather than papered over: only three of the 28 diagrams were
remade. The repository forbids hand-drawn SVG and forbids titles inside the
canvas; all 28 originals carry both, so converting them is redrawing, not
reformatting. They stay in source/ and the gap is written into the document.

verify-pipeline.py passes. audit-records.py reports no issues.

# 같은 두 검사를 두 예외 계층이 나눠 갖는다
보안 판정이 두 예외 계층으로 나뉜다. BrokerTlsPolicy는 안정 코드가 붙은 MessagingConfigurationException을 쓰고, MessageSecurityValidator는 코드 없는 IllegalArgumentException을 쓴다.
## 관계
- **배선된 게이트는 자기 leaf 레인에서 검증한다**
같은 분석 리프에서 끌어낸 규칙이다.
- **같은 술어가 두 타입에 있으면 하나가 다른 하나를 부른다**
같은 분석 리프에서 끌어낸 규칙이다.
- **가변 필드로 상태 전이를 표현하면 가시성을 함께 정한다**
같은 분석 리프에서 끌어낸 규칙이다.
- **맵 갱신 함수 안에서 I/O를 하면 그 지연이 락 범위가 된다**
같은 분석 리프에서 끌어낸 규칙이다.
## 본문
<!-- body:start -->
실패가 두 계층으로 나뉜다.
| 코드 | 예외 | 위치 |
|---|---|---|
| `TLS_REQUIRED` | `MessagingConfigurationException` | `BrokerTlsPolicy` |
| `HOSTNAME_VERIFICATION_REQUIRED` | `MessagingConfigurationException` | 같음 |
| `TLS_PROTOCOL_NOT_ACCEPTED` | `MessagingConfigurationException` | 같음 |
| `TLS_PROTOCOL_UNSPECIFIED` | `MessagingConfigurationException` | 같음 |
| `APPLICATION_HOLDS_DESTRUCTIVE_GRANT` | `MessagingConfigurationException` | `BrokerAclManifest`(미사용) |
| `DESTINATION_PUBLISH_DENIED` | `MessageAuthorizationException` | `DestinationAccessValidator`(미사용) |
| `DESTINATION_CONSUME_DENIED` | `MessageAuthorizationException` | 같음(미사용) |
| `DESTINATION_ADMIN_DENIED` | `MessageAuthorizationException` | 같음(미사용) |
| (코드 없음) | `IllegalArgumentException` × 5 | `MessageSecurityValidator` |
| (코드 없음) | `IllegalArgumentException` | `CredentialIds`, 각 생성자 |
| (코드 없음) | `IllegalStateException` | `CredentialRuntime.material()` 소거 후 |
## BrokerTlsPolicy 참조 위치
:::evidence key="messaging-security-c05" alt="코드베이스에서 BrokerTlsPolicy 를 검색한 출력 28줄. 이 기록이 세는 참조가 그 출력에 그대로 보인다." caption="BrokerTlsPolicy 코드베이스 검색 — 28줄 · exit 0" zoom="true"
:::
## 나뉘는 지점
`BrokerTlsPolicy`는 안정 코드가 붙은 `MessagingConfigurationException`을 쓰고, `MessageSecurityValidator`는 코드 없는 `IllegalArgumentException`을 쓴다. 둘이 같은 두 검사(TLS·hostname)를 공유하는데도 그렇다 — §12.3, §17.
