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.

# 캐시 헤더를 소유하는 것은 24줄 상수 두 개다

배선된 `CacheControlFilter`는 `@Component`라 컴포넌트 스캔이 잡고 모든 응답에 `no-store`를 붙인다. 프로파일·지시자·`Vary` 규칙을 갖춘 `cache` 패키지 4파일 310 LOC은 배선되지 않았다.

배선된 쪽은 `CacheControlFilter`다. `@Component`이므로 컴포넌트 스캔이 잡고 Spring이 `Filter` 빈을 체인에 넣는다. **모든 응답에 `no-store`를 붙인다.** 배선되지 않은 것은 `cache` 패키지 4개 파일 310 LOC이고, `web.cache.` 패키지를 참조하는 파일이 자기 패키지 밖에 **0개**다.

## 소유자를 지목하는 주석과 실제 소유자

`SecurityConfig:80`이 Spring Security의 기본 캐시 헤더 작성기를 끄면서 그 이유를 적는다 — "`CacheControlFilter` **owns the cache header policy**". 소유자는 24줄짜리 상수 두 개이고, 프로파일·지시자·`Vary` 규칙을 갖춘 310줄은 소유하지 않는다.
