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.

# vendor migration 아홉을 실제 PostgreSQL에서 적용했다
|
|
|
|
9개 migration을 모두 읽고 실제 PostgreSQL probe에서 Flyway가 전부 validate/apply했다.

다음 9개 migration을 모두 읽었다. 확인한 경계는 이렇다.
|
|
|
|
- idempotency owner/state/replay/transition metadata의 persisted shape
|
|
- outbox claim/delivery/index shape
|
|
- integer advisory/row-lock support table과 expiry extension
|
|
- capability schema registry adoption/widening
|
|
- request hash `char`/`varchar` drift 보정
|
|
- durable operation / live-event log schema
|
|

## 실제 적용 결과와 남긴 범위
|
|
|
|
real PostgreSQL probe에서 Flyway는 vendor 9 migrations를 모두 validate/apply했다. 이번 sub-scope에서 migration 순서, 현재 schema 제약, index 선언 자체로 승격할 신규 defect는 확인하지 못했다. capability-specific migration의 완전한 cross-stream adoption은 각 owning capability scope에서 다시 본다.
