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.

# 상호배타성이 프로퍼티가 아니라 타입에서 온다
|
|
|
|
MVC와 WebFlux 자동설정 둘 다 `matchIfMissing = true`로 기본 켜짐이다. 두 아티팩트가 클래스패스에 함께 있어도 하나만 활성화되는 이유는 프로퍼티가 아니라 `@ConditionalOnWebApplication`의 타입 조건이다.
|
|
|
|
## 본문
|
|
|
|
<!-- body:start -->
|
|
|
|
두 자동설정의 게이트는 이렇게 붙어 있다.
|
|
|
|
```text
|
|
MVC: @ConditionalOnWebApplication(SERVLET) + @ConditionalOnProperty(backend.web.mvc.enabled, matchIfMissing = true)
|
|
WebFlux: @ConditionalOnWebApplication(REACTIVE) + @ConditionalOnProperty(backend.web.webflux.enabled, matchIfMissing = true)
|
|
```
|
|
|
|
둘 다 `matchIfMissing = true` — **기본 켜짐**이다. notification·messaging·cache-redis가 전부 `matchIfMissing = false`(옵트인)인 것과 반대인데, 이유가 다르다: 저쪽은 선택적 능력이고 이쪽은 웹 애플리케이션의 본체다.

## 활성화를 가르는 것

|
|
|
|
상호배타성은 프로퍼티가 아니라 `@ConditionalOnWebApplication`의 타입 수준에서 온다 — "a reactive application cannot accidentally activate the servlet filters even if both artifacts are on the classpath."

|
## 등록되는 빈 수
|
|
|
|
두 자동설정이 등록하는 빈은 MVC 12개, WebFlux 11개다. `AutoConfiguration.imports`에는 이 둘만 있다.
