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.

## 5. P3 — R1과 R2의 설정 취급이 비대칭이고, 검증된 쪽은 하나뿐이다
|
|
|
|
같은 leaf 안의 두 selector가 설정을 다르게 다룬다.
|
|
|
|
| | R2 `app.fileserver.*` | R1 `app.file-export.*` |
|
|
|---|---|---|
|
|
| 바인딩 타입 | `record` + **`ignoreUnknownFields = false`** | 가변 JavaBean, 기본값(**미지의 키 무시**) |
|
|
| 루트 경로 | `requireAbsoluteNormalizedPath` — 이미 절대·정규화여야 함 | `Path.of(v).toAbsolutePath().normalize()` — 상대 경로 허용, CWD 기준 절대화 |
|
|
| 기본 루트 | 없음(필수) | `./.data/fileserver`, `./.data/fileserver-legacy` |
|
|
| 디렉터리 생성 | 하지 않음(attestation이 별도로 요구) | `Files.createDirectories(root)`로 **생성** |
|
|
| 미지 키 test | `unknownConfigurationFieldIsRejectedInsteadOfSilentlyIgnored` | **없음** |
|
|
|
|
R2에서는 `strict-path-securty` 같은 오타가 컨텍스트를 실패시킨다. R1에서는 `app.file-export.maximum-rowz=10` 같은 오타가 조용히 무시되고, 설정했다고 믿는 상한이 적용되지 않은 채 기본값 1,000,000이 쓰인다. 두 selector가 같은 leaf의 같은 성격 설정인데 한쪽만 fail-closed다. **P3** — R1은 문서상 "compatibility only"이므로 우선순위를 낮춘다.

## 6. P3 — 문서가 지목한 기본값 위치와 test 목록이 실제와 다르다
