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.

### 17.1 P2 — insert-first 주장이 Spring Data 의 `save` 계약과 어긋난다. 그리고 테스트 이중이 그 차이를 가린다

어댑터는 이렇게 쓴다.
|
|
|
|
```java
|
|
try {
|
|
repository.save(GrpcOperationLedgerEntity.claim(identity, requestFingerprint, now));
|
|
return Optional.empty(); // 내가 이겼다
|
|
} catch (DataIntegrityViolationException alreadyClaimed) {
|
|
return repository.findById(identity.storageKey()).map(entity -> entity.toRecord(identity));
|
|
}
|
|
```
|
|
|
|
전제는 `save` 가 INSERT 이고, 같은 신원의 두 번째 청구가 유니크 제약을 건드린다는 것이다.
