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.

발견과 전송은 다른 경로다

두 노드가 데이터베이스로는 이어져 있고 TCP 7800 으로는 끊긴 구성. 세션 조회는 살아 있고 무효화 통지는 막힌다.
Long description
노드가 서로를 찾는 경로와 실제로 이야기하는 경로가 다르다. 발견은 PostgreSQL 의 JGROUPS_PING 테이블을 쓰고 전송은 TCP 7800 을 쓴다. 7800 만 막으면 둘 다 데이터베이스에 등록된 채로 남아 서로 존재한다고 믿지만 메시지는 오가지 않는다. 세션은 데이터베이스에 있으므로 교차 노드 refresh 는 200 을 유지하고, 로그아웃 무효화 통지는 7800 을 타므로 400 이어야 할 것이 200 이 된다.
Elements and evidence
- keycloak-0 (service): 로그아웃을 처리한 노드. Evidence: L183–L189.
- TCP 7800 (channel): 무효화 통지가 지나는 길. NetworkPolicy 로 막았다. Evidence: L191–L196.
- keycloak-1 (service): 통지를 못 받아 세션이 죽은 것을 모른다. Evidence: L183–L189.
- PostgreSQL (datastore): 세션이 여기 있어 7800 과 무관하다. Evidence: L186–L190.
Relationships
- keycloak-0 → TCP 7800: 무효화 통지. Evidence: L186–L190.
- keycloak-1 → PostgreSQL: 세션은 여기서 읽는다 — 7800 과 무관. Evidence: L186–L189.
- TCP 7800 → keycloak-1: 막혀서 닿지 않는다. Evidence: L186–L190.
