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.

여섯 갈래 원인이 하나의 코드로 접힌다

전부 retryable = false다 — PERMANENT_BUSINESS와 DESERIALIZATION 카테고리다. 같은 바이트를 다시 디코딩해도 같은 결과이므로 일관적이다.

관계

  • 실패 코드는 운영자의 다음 행동이 갈리는 지점마다 나눈다 같은 분석 리프에서 끌어낸 규칙이다.

진단 손실 하나

파서 강화가 잡는 여섯 가지(깊이, 중복 키, trailing token, 미지 필드, 문서 길이, 토큰 길이)가 전부 하나의 코드 JSON_DECODE_FAILED로 접힌다. 운영자는 "JSON 디코딩 실패"만 보고 원인 여섯 갈래를 구분할 수 없다.

원인은 붙지만 분류에는 남지 않는다

원인 예외가 cause로 붙지만 FailureDescriptorexceptionTypeOptional.empty()로 둔다(MessageSerializationException의 3인자 생성자 경로). §17 참조.
