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.

`ObjectOperationStateMachine`이 publication·scan·reference·direct-grant·multipart 다섯 계열의 전이를 각각 switch로 적고, terminal 처리가 계열마다 명시적이다.

`ObjectOperationStateMachine`이 publication·scan·reference·direct-grant·multipart 다섯 계열의 전이를 각각 switch로 적는다. terminal 처리가 계열마다 명시적이다.

뒤 둘은 **branch 전이**(EXPIRED/ABORTED/FAILED/CORRUPT)를 별도로 허용해, 정상 사슬 어디서든 실패로 빠질 수 있되 terminal에서는 나올 수 없게 한다.

`requireNextRevision(current, next)`가 `next == current + 1`을 강제한다. `ObjectOperationStateMachineTest`가 셋을 이름으로 고정한다: `publicationFollowsScanFreeAndScanRequiredPaths`, `terminalOutOfOrderAndStaleRevisionTransitionsFailClosed`, `independentStateFamiliesDoNotImplyEachOther`.
