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.

### 17.7 P3 — 오류 노출 거부 목록의 "호스트와 포트" 규칙이 IPv4 점표기만 본다
|
|
|
|
```java
|
|
Pattern.compile("\\b\\d{1,3}(\\.\\d{1,3}){3}(:\\d{1,5})?\\b"),
|
|
```
|
|
|
|
아홉 패턴을 전부 읽으면 주소 형태를 보는 것은 이 하나다. 클래스 javadoc 은 거부 대상을 "a stack frame, a SQL fragment, a JDBC URL, a bearer token, **a host and port**, a file path" 로 서술하는데, 실제로 걸리는 host 는 IPv4 점표기뿐이다.
|
|
|
|
통과하는 것들:
|
|
|
|
- IPv6 리터럴 — `fe80::1`, `[2001:db8::1]:5432`
|
|
- DNS 이름과 포트 — `documents-db.internal:5432`, `kafka-0.kafka-headless:9092`
|
|
|
|
`jdbc:postgresql://db/app` 이 막히는 것은 host 규칙이 아니라 `jdbc:` 규칙 때문이다. 즉 이 구멍은 테스트에도 없다 — `exposurePolicyRefusesLeakyStrings` 의 아홉 사례 중 주소는 `upstream 10.0.3.14:5432 refused` 하나이고 IPv4 다.
