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 런타임 — 스레드 규율이 설계다

공개 API 인 pause/resume 도 제어 큐를 통해 폴 스레드로 넘어가고, 반환된 단계는 다음 폴 주기 에 완료된다. close() 만 예외이고 그 예외에 근거가 붙어 있다 — 이후 폴 루프가 멈추므로 큐에 넣으면 영원히 배수되지 않는다.

본문

공개 API 인 pause/resume 도 제어 큐를 통해 폴 스레드로 넘어가고, 반환된 단계는 다음 폴 주기 에 완료된다.

폴 스레드가 소유한 것

:::evidence key="messaging-kafka-c01-diagram" alt="consumer 객체와 제어 큐 배수가 폴 스레드 안에 놓이고 작업자 람다가 바깥에 빗금으로 놓인다" caption="폴 스레드가 소유한 것" zoom="false" :::

close 만 예외인 이유

이후 폴 루프가 멈추므로 큐에 넣으면 영원히 배수되지 않는다.

이 기록이 다루는 범위

규율이 실제로 지켜진다

작업자 람다가 만지는 것은 settlements·coordinator·shutdown·retries 뿐이고 consumer 는 한 번도 없다. 통독으로 확인했다.
