The originating repository's SVGs were drawn by hand and every one of them
put a title, a subtitle and an explanation band inside the canvas. This
repository forbids both, so they could not be carried over — the whole set
was rebuilt through the skill's pipeline instead.
Each diagram went through prepare, references, prompt, a VizSpec 1.1 citing
document line ranges, lint, and render. All 28 pass lint and produce the
same eight formats the existing keycloak project has. Sentences moved out of
the canvas into <desc> and the paragraph beside each figure; the drawings
carry names only.
Two lint rules did real work rather than formatting work:
edge-through-node caught arrows crossing an unrelated
node and implying an adjacency that
does not exist — four diagrams had to
be restructured, not just relaid out
evidence-outside-prepared-context caught a diagram citing another
section; its anchor moved from B-0 to
B-1 so all three sections it draws on
are inside the prepared context
lab-topology also had to change profile: its context offers a different
candidate set, and query-fanout with shard roles is what the section
actually shows — one entry point spreading to two Keycloak nodes.
The document now carries all 28 inline, one per claim that needed one, and
the section recording what was still missing is updated: the diagram gap is
closed, Studio records remain.
verify-pipeline.py passes. audit-records.py reports no issues.

# 노드를 잃는 두 가지
|
||
|
||
## Alternative text
|
||
|
||
kc-lab-2 를 잃으면 데이터베이스가 함께 사라지고, kc-lab-1 을 잃으면 진입 경로가 사라지는 구성.
|
||
|
||
## Long description
|
||
|
||
kc-lab-2 를 잃으면 keycloak-1 은 살아 있지만 PostgreSQL 이 같이 죽어 외부 응답이 503 이 된다. kc-lab-1 을 잃으면 keycloak-0 은 계속 돌고 있는데 traefik 과 API 서버가 사라져 연결 자체가 안 된다. 워크로드가 멀쩡한데 도달할 수 없어 장애다. 진입점이 단일 노드에 있으면 워크로드 이중화는 의미가 없다.
|
||
|
||
## Elements and evidence
|
||
|
||
- **외부 요청** (actor): 사용자. Evidence: L221–L228.
|
||
- **진입 경로 (kc-lab-1)** (gateway): traefik 과 API 서버. 잃으면 000 이다. Evidence: L221–L231.
|
||
- **keycloak-0 (kc-lab-2)** (service): 4b 에서는 계속 돌고 있었다. Evidence: L221–L231.
|
||
- **PostgreSQL (kc-lab-2)** (datastore): 4a 에서 함께 죽는다. 잃으면 503 이다. Evidence: L221–L233.
|
||
|
||
## Relationships
|
||
|
||
- **외부 요청 → 진입 경로 (kc-lab-1):** 요청. Evidence: L221–L228.
|
||
- **진입 경로 (kc-lab-1) → keycloak-0 (kc-lab-2):** 라우팅. Evidence: L221–L228.
|
||
- **keycloak-0 (kc-lab-2) → PostgreSQL (kc-lab-2):** 세션 조회. Evidence: L221–L233.
