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.

# 소비자 없음과 membership 없음이 일치한다
들어오는 것: messaging-core-api(api), messaging-schema-api(api), avro:1.12.0(api). 나가는 것: 없다.
## 관계
- **모드 enum을 분기 조건으로 쓰면 각 분기에 테스트를 둔다**
같은 분석 리프에서 끌어낸 규칙이다.
- **컬렉션 순서가 계약이면 양쪽에서 같은 방향으로 적는다**
같은 분석 리프에서 끌어낸 규칙이다.
- **안정 코드는 판단 단위로 정하고 구현 단위로 정하지 않는다**
같은 분석 리프에서 끌어낸 규칙이다.
## 본문
<!-- body:start -->
들어오는 것은 `messaging-core-api`(api), `messaging-schema-api`(api), `avro:1.12.0`(api)다. 나가는 것은 **없다** — 어떤 leaf의 `allowed_dependencies`에도 `messaging-schema-avro`가 없고, `messaging-spring-boot-starter`의 17개 의존 목록에도 없다.
## 이 기록이 다루는 범위

:::
## 런타임 배선 없음
`runtime_memberships: []`이므로 배포 아티팩트에 실리지 않는다. bean도 없다(Spring 주석 0개).
## 정합적인 incubating 상태
소비자 없음과 membership 없음이 일치한다. `messaging-cloudevents`와 대비된다 — 그쪽은 membership이 있고 소비자가 없다.
