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.

## 96. P3 — 소비자가 없는 fixture 셋
|
|
|
|
`138-...` §8.1의 소비자 계수에서 test·testkit 양쪽 모두 0인 타입이 셋이다.
|
|
|
|
| 타입 | 무엇을 위한 것인가 |
|
|
|---|---|
|
|
| `MongoAtlasLocalContainer` | Atlas Local 컨테이너 — search·vector 계약의 빠른 피드백용. `MongoAtlasCapabilityContractSuite`(report 타입)는 test 1곳에서 쓰이지만, **실제 컨테이너를 띄우는 곳은 없다** |
|
|
| `MongoChunkMigrationController` | 트래픽 중 청크 이동 — "production hits during a rebalance"를 재현하는 유일한 장치 |
|
|
| `MongoRoundTripContract` | Java → BSON → **서버** → raw BSON → Java 왕복. javadoc: "Half a round trip proves nothing… only the raw BSON in the middle shows it" |
|
|
|
|
셋째가 가장 무겁다. `MongoReleaseContract`의 형제인 `MongoReplicaSetContract`는 `GOLDEN_BSON`을 열거된 계약으로 두는데, 그 계약을 실행하도록 만들어진 타입에 호출자가 없다. `MongoBsonSnapshot`·`MongoBsonSnapshotAssert`는 쓰이므로 **정규형 단언은 존재하지만 서버를 통과하는 왕복은 돌지 않는다** — 그리고 그 차이가 정확히 이 클래스가 존재하는 이유다. **P3.**

- **8.1 reachability**: 33개 testkit 타입의 소비자를 계수. 셋이 0(§96). 나머지는 test 또는 testkit 안에서 사용됨.
