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.

## 본문

<!-- body:start -->

|
|
`ContractCatalogCompiler`가 **정확한 record 타입 토큰**으로부터 불변 카탈로그를 만들고, test 이름이 무엇을 거부하는지 전부 적는다 — 중복 stable/schema/payload 신원, 음수 버전, 잘못된 payload kind, null·공백·중복·반사 불일치 성분 순서, 서술자 누락, **payload 버전 사이의 logical destination 드리프트**.

## 그래프가 닫혀 있어야 스냅샷할 수 있다
|
|
|
|
`recursivelyFreezesOnlyTheClosedDeclaredGenericPayloadGraph` / `rejectsOpenRawWildcardMapJsonTreeInterfaceAndGenericRecordGraphs` — 열린 타입(raw·wildcard·`Map`·JSON 트리·인터페이스·제네릭 record 그래프)을 페이로드로 받지 않는다. 봉투 작성기가 shape을 따라 스냅샷할 수 있으려면 그래프가 닫혀 있어야 한다(§11).
|
|
|
|
## 접근자를 정확히 한 번만 부르는 이유
|
|
|
|
`snapshotsEveryContributionAccessorExactlyOnceIncludingAStatefulSchemaHash` / `statefulDescriptorCannotBypassCrossVersionLogicalDestinationDrift` — 기여 접근자를 **정확히 한 번만** 호출한다. 가변 서술자가 검사와 저장 사이에 값을 바꿔 규칙을 우회하는 경로를 닫는다.
|
|
|
|
## 반사가 밖으로 새지 않는다
|
|
|
|
`compiledContractUsesOnlyAStaticPublicCompositionBridgeWithoutReflectionLeak` — 컴파일된 계약이 반사를 밖으로 새게 하지 않는다.
