The skill says drawings carry names and sentences go in <desc> and the paragraph beside the figure. I put sentences in node details and edge labels instead, and 27 of the 28 diagrams shipped with prose inside the canvas — "예측 다섯 개가 틀렸다", "아홉 번 조용히 실패했다", "막혀서 닿지 않는다". Only label and details render on the canvas; description does not. So every sentence moved to a noun phrase and the meaning stays in description, which was already carrying it. 막혀서 닿지 않는다 -> 차단 아홉 번 조용히 실패했다 -> 조용한 실패 9건 예측 다섯 개가 틀렸다 -> 틀린 예측 5건 로그아웃이 정리하지 않는다 -> 로그아웃 미정리 볼륨이 없으면 여기까지다 -> 볼륨 없음 Three node labels were sentences too and became names: 세션 스냅샷, 예측 선기록, 대조군 확보. What stays is what the rules protect — identifiers, commands and measured values: PRIMARY KEY (client_registration_id, principal_name), ValidationFailedException: 1 changesets check sum, nginx -t && nginx -s reload, SET LOCAL synchronous_commit TO OFF. Those are names of things, not prose about them. 294 canvas strings across 28 diagrams, none matching a sentence ending, average 11 characters. All 28 still lint clean and re-rendered.

<desc id="diagram-description">Keycloak 은 트랜잭션마다 SET LOCAL synchronous_commit TO OFF 를 건다. PostgreSQL 은 COMMIT 을 WAL 디스크 기록을 기다리지 않고 즉시 반환하고, 클라이언트는 200 과 토큰을 받는다. 실측된 wal_writer_delay 는 200ms 이며 그 사이에 프로세스가 죽으면 그만큼이 사라진다. 153건 중 4건이 그렇게 유실됐다. 버그가 아니라 의도된 설계이고 그 대가를 숫자로 확인한 것이다.</desc>
