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.

### P3 — 종료 시 자격증명 소거가 호출되지 않는다
|
|
|
|
- **사실.** `CredentialRuntimeRegistry.clearAll()`의 javadoc이 "Clears every held credential, for shutdown"이라고 하고, 호출자가 저장소에 없다.
|
|
- **근거.** `git grep -n 'clearAll' -- src`.
|
|
- **왜 문제인가.** 이 leaf 전체가 "비밀이 힙에 남지 않게 한다"를 목적으로 하고(`char[]`, `clear()`, 회전 시 즉시 소거), 종료 경로에서 그 마지막 단계가 빠져 있다. 프로세스가 끝나면 힙도 사라지지만, 종료가 느리거나 힙 덤프가 뜨는 경우가 정확히 이 통제가 노리는 상황이다.
|
|
- **확인 방법.** `git grep -n 'clearAll' -- src` → 선언과 테스트만.
|
|
- **후보.** `MessagingShutdownLifecycle`이나 `DisposableBean`에 연결한다.
|
|
- **다음 단계.** **CASE 후보.** `messaging-transport-spi` §12.1의 8단계 종료 계약과 같은 맥락이다.
|
|
|
|
### P3 — 회전 술어가 두 번 구현돼 있고, 쓰이지 않는 쪽이 테스트된다
|
|
|
|
- **사실.** `CredentialRotationPlan.isDue`/`isExpired`와 `CredentialRuntime.isDueForRotation`/`isExpired`가 글자까지 같다. 전자는 소비자 0이고 전용 테스트(`CredentialRotationContractTest`, 4개)가 있다.
|
|
- **근거.** `evidence/raw/287` §E.
|
|
- **왜 문제인가.** 테스트가 고정하는 것과 실행되는 것이 다른 객체다. 한쪽만 고치면 다른 쪽은 조용히 다른 시점에 회전한다.
|
|
- **확인 방법.** 두 메서드 본문 대조.
