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.

# R4인데 BLOCKED이 아닌 정책 파일은 읽히지 않는다
`RedisCommandPolicyLoader`가 일반 YAML 파서를 쓰지 않고, 교차 필드 불변식이 로딩 시점에 적용된다.
## 본문
<!-- body:start -->
`RedisCommandPolicyLoader`의 javadoc이 일반 YAML 파서를 쓰지 않는 이유를 적는다. 파서는 그만큼 좁다 — 탭 금지, 들여쓰기 0/2/4만 허용, `commands:` 루트 정확히 하나, 명령 블록 중복 금지, 필드 이름 allowlist(12종) 밖이면 거부, 빈 값 거부, 필드 중복 거부. test가 `rejectsUnknownFieldsEnumsAndDuplicates`로 잡는다.
## RedisCommandPolicyLoader 참조 위치

## 모순된 정책 파일은 읽히지 않는다
`RedisCommandPolicy`/`RedisCommandDescriptor`의 교차 필드 불변식(§24)이 로딩 시점에 적용되므로, "R4인데 BLOCKED이 아닌" 정책 파일은 **읽히지 않는다**.
