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.

# 구독 경로가 guard를 건너뛰고 대신 세우는 검사
`PubSubOperationRequests`의 javadoc이 guard를 지나지 않는 경로를 스스로 밝히고, 그 자리에 어떤 검사를 대신 두었는지도 함께 적는다. 대체 검사는 실제로 존재한다.
## 본문
<!-- body:start -->
`PubSubOperationRequests`의 javadoc이 예외를 스스로 밝힌다. 발행은 보통의 명령이라 guard를 지나지만 구독은 지나지 않고, 경계 지을 응답도 적용할 타임아웃도 없어서 guard가 검사할 대상 자체가 없다는 것이 그 이유다. 대체 검사가 실제로 있다.
## 구독이 guard 대신 통과하는 세 검사
`channelTargets`·`shardTargets`·`patternTargets` 셋 다 빈 컬렉션을 거부하고 **모든 대상의 네임스페이스가 이 프로세스의 것과 같은지** 확인한다(`requireNamespace`, 다르면 "channel belongs to a namespace this process may not use"). `patternTargets`는 추가로 `context.sdkPermit(PATTERN_SUBSCRIBE)`를 호출한다. 팬아웃 폭을 요청이 아니라 서버가 정하기 때문이다.
