DongHyeonkaandClaude Opus 5 b2963105a8 docs(keycloak-session-store): import the session-storage lab as a new project
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
:::evidence key="adapter-inbound-web-c01-diagram" alt="웹 애플리케이션 타입에서 MVC 자동설정과 WebFlux 자동설정으로 각각 화살표가 나가고 화살표에 SERVLET 과 REACTIVE 가 붙은 구조" caption="타입이 고르는 자동설정" zoom="false"
:::
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.
