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.

위협은 실패가 아니라 잘못된 성공이다

브로커 한계를 넘는 payload를 객체 저장소에 두고 메시지는 참조만 나른다. 위협 모델은 "decode perfectly into the wrong object"다.

관계

  • leaf의 각 public 클래스는 자기 레인에 테스트를 갖는다 같은 분석 리프에서 끌어낸 규칙이다.
  • 같은 튜닝 값이 두 계층에 있으면 어느 쪽이 이기는지 정한다 같은 분석 리프에서 끌어낸 규칙이다.

본문

Claim Check 패턴 — 브로커 한계를 넘는 payload를 객체 저장소에 두고 메시지는 참조만 나른다. messaging-reliability-apiClaimCheckReference(storageKey·sizeBytes·sha256·expiresAt)를 값 타입으로 쓰고, 이 leaf가 그것을 만들고 검증하는 동작을 소유한다.

이 리프의 위협 모델

경계 진술이 두 클래스에 있다. **"decode perfectly into the wrong object"**가 이 leaf의 위협 모델이다 — 실패가 아니라 잘못된 성공.
