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.

닫을 자원이 없어서 두 번 닫아도 무해하다

ShareRegistration.activeAtomicBoolean이고 close()set(false)이므로 멱등이다. 수명주기 참여가 없다.

관계

  • 허용 의존 목록은 상한이므로 미사용을 잡지 않는다 — 그것을 잡으려면 별도 검사가 필요하다 같은 분석 리프에서 끌어낸 규칙이다.
  • leaf의 각 public 클래스는 자기 레인에 테스트를 갖는다 같은 분석 리프에서 끌어낸 규칙이다.
  • 에러 메시지가 지시하는 설정은 그 설정을 읽는 코드와 함께 존재해야 한다 같은 분석 리프에서 끌어낸 규칙이다.
  • 구성 오류는 한 예외 타입과 안정 코드로 보고한다 같은 분석 리프에서 끌어낸 규칙이다.

본문

ShareRegistration.activeAtomicBoolean이다. close()set(false)이고 CAS가 아니므로 두 번 닫아도 무해하다(멱등).

ShareRegistration 참조 위치

상태를 갖는 것과 갖지 않는 것

KafkaShareProfileValidator·KafkaShareWorkQueueCapability는 상태가 없다. KafkaShareGroupRegistrar는 validator 참조 하나만 갖는다.

수명주기 참여가 없는 이유

TransportConsumerRegistrationAutoCloseable이지만 이 구현은 닫을 자원을 갖지 않는다.
