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.

# 렌더된 키 문자열을 받는 API가 없다
|
|
|
|
`QualifiedRedisKey`의 javadoc이 이 계층의 규칙이다 — 이미 렌더된 키 문자열을 받는 API가 없으므로 네임스페이스·슬롯·크기 규칙을 우회할 수 없다. 구조가 그것을 강제한다.
|
|
|
|
## 본문
|
|
|
|
<!-- body:start -->
|
|
|
|
`QualifiedRedisKey`의 javadoc이 이 계층의 규칙이다 — "This is the only key shape the SDK accepts. **There is no API that takes an already rendered key string**, so namespace, slot, and size rules cannot be bypassed."
|
|
|
|
## 타입이 강제하는 형태
|
|
|
|
`RedisTypedKey`는 9종만 허용하는 sealed interface고(`ValueKey`·`HashKey`·`ListKey`·`SetKey`·`SortedSetKey`·`BitmapKey`·`HyperLogLogKey`·`GeoKey`·`StreamKey`), 전부 `QualifiedRedisKey` + 코덱으로 구성된다. `QualifiedRedisKey`는 `RedisNamespace`(토큰 3개) + `RedisKeyName`(entity 토큰 + identifier) + 선택적 `RedisSlotTag`다. 그리고 `RedisKeyRenderer`가 **중괄호를 쓰는 유일한 장소**라서 Cluster 해시 태그가 "the tag and nothing else"를 덮는다.

## 이 검사가 PII 방지의 완결이 아니라고 적는다
|
|
|
|
`RedisKeyRules`의 자기 한정도 정직하다 — 규칙은 "mechanical"이며 "Values that are indistinguishable from an ordinary surrogate identifier, such as a bare digit string, cannot be rejected here; those must be fingerprinted by the caller before they become a key part."
