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.

파일	무엇을 보여주는가
`01-restart-availability.txt`	재시작 전 로그인(sid 기록), 롤링 재시작 중 외부 진입점 9회 모두 `200`
`02-session-survival.txt`	재시작 전 토큰으로 refresh `200`, DB 행 생존(`last_session_refresh` 갱신 확인), 세션 수 151 → 151, 캐시 0으로 초기화, 파드 나이 44초/66초
`a8-cache-reset-cluster-reformed.png`	Grafana — 세션 캐시가 0 으로 떨어지고 `cluster_size` 가 다시 2 가 되는 구간

핵심 세 줄

무중단이었다. 한 번에 하나씩 내리고 readiness 가 전환을 맞춰준다 — replica ≥ 2 가 전제.
세션은 살아남고 캐시만 사라진다. DB 151건 그대로, 재시작 전 토큰이 그대로 통한다.
이것이 persistent-user-sessions 를 켜는 진짜 이유다. A-7(volatile)에서 정반대가 나와야 한다.
