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.

# 판정
|
|
# 1) messagingCertificationTest 가 실제 apache/kafka:4.1.0 + toxiproxy 컨테이너에 대해 실행되었다.
|
|
# 2) verifyMessagingCertificationEvidence 가 생산물과 커밋본을 비교해 통과했다.
|
|
# (gitCommit·observedAt 은 정규식으로 제거 후 비교 — 그 설계는 messaging-kafka/build.gradle 에 명시)
|
|
# 생산본의 gitCommit 은 "local"(GITHUB_SHA 미설정 시 기본), 커밋본은 e98b56eb.
|
|
# 나머지 필드 — adapter, brokerImage, scenario, testId, outcome — 는 4줄 모두 일치했다.
|
|
# => **커밋된 인증 매니페스트는 이 revision 에서 레인이 실제로 생산하는 것과 동일하다.**
|
|
# analysis/messaging/messaging-testkit.md §16 이 "확인하지 못한 것" 으로 남긴 두 항목
|
|
# ("매니페스트 4줄이 실제 실행에서 나왔는지", "게이트가 실제로 도는지")이 여기서 닫힌다.
|
|
#
|
|
# 3) 5개 시나리오 중 connection-refused 는 여전히 증거가 없다. 이는 결함이 아니라
|
|
# CertifiedEvidenceTest 가 명시적으로 단언하는 알려진 gap 이다
|
|
# ("a Kafka producer buffers before it learns a connection exists, so this stays unproven").
|
|
|
|
# 참고: 일반 `test` 레인에는 KafkaBrokerCertificationIT 가 포함되지 않는다.
|
|
# command: ./gradlew :messaging:messaging-kafka:test --rerun-tasks (아래 EVD-320)
|
|
# 결과 XML 에 KafkaBrokerCertificationIT 가 없다 — excludeTags 'messaging-certification' 대로다.
