docs(clean-architecture-backend-template): 제1부가 채택한 것만 글감으로 남기고 다시 고른다

Browse Source 
글감 1,001개 중 제1부(§3~§11) 앵커를 하나라도 가진 것은 112개뿐이었다. 나머지 889개는
제2부 모듈 분석 65편의 절 제목에서 나온 것이고, 그것이 재판정이 필요했던 이유다.

  주제      44 → 16   (43개가 독자 질문 없이 있었다. 지금은 전부 있다)
  글감   1,001 → 123  (제1부 앵커 112 + 제1부가 채택했는데 비어 있던 자리 11)
  후보      965 → 1,088 · PENDING 905 → 0
  error   3,042 → 0

내려온 889개는 후보 대장에 KEEP_IN_SSOT 로 남는다 — 버린 것이 아니라 분석에 남기고 독립
기록으로 만들지 않기로 한 것이다. 그 글감을 받치던 기록 파일 828개는 지웠다. 계약이 정본이고,
파일이 남아 있다는 이유로 계약에서 뺀 주제가 되살아나면 안 된다. 이력에는 그대로 있다 —
git checkout a0ca2bb -- <경로>.

제1부가 채택했는데 글감이 없던 자리 열하나를 채웠다: mongo high-water mark 가 재전달 이벤트를
삼킨 P1, admin plane 이 가드만 켜고 서비스는 켜지 않은 것과 그 짝인 결정, 실패 어휘 세 층과
SQLState 매트릭스 병합 규칙, 부하 아래에서만 새는 admission 경계, 발행 증거와 완료 판정의
분리, keyset·JSONB 결정 둘.

Concept 17개에 basis-version 을 채우고, 계약 제목과 기록 제목이 갈라져 있던 23건을 기록 쪽에
맞췄다. candidateScope 에 excludedAnchorPattern 을 적어 제2부 앵커만 가진 글감이 다시 올라올
수 없게 한다.

<desc id="diagram-description">브라우저가 Authorization header 없이 AP3_SESSION cookie로 /bff/api/me를 호출한다. BFF는 현재 Authentication으로 authorized-client manager를 호출해 server-held access token을 얻고 Resource Server의 /api/me에 Bearer header를 붙인다. Resource Server가 JWT를 검증해 사용자 JSON을 반환하면 BFF가 ResponseEntity로 받아 브라우저에 중계한다. 브라우저 session cookie는 downstream으로 전달되지 않는다.</desc>

<desc id="diagram-description">왼쪽의 BFF CSRF endpoint에서 두 결과가 갈라진다. XSRF-TOKEN cookie에는 raw token이 저장되고 JSON body에는 XOR와 Base64로 masked된 token 및 headerName이 담긴다. 두 결과는 SPA의 POST 조립 단계로 모이지만, JSON에서는 headerName만 사용하고 실제 X-XSRF-TOKEN 값은 document.cookie에서 읽은 raw token이다. POST에는 같은 raw 값을 가진 cookie와 header가 함께 도달하고 Spring CSRF filter가 일치 여부를 확인한다.</desc>

<title id="diagram-title">AP4 proxy session에서 trusted identity JSON까지</title>
<desc id="diagram-description">브라우저가 AP4_SESSION cookie로 Nginx의 /api/edge를 호출한다. Nginx는 oauth2-proxy의 internal auth endpoint에 subrequest를 보내고 인증된 user와 email 결과를 받는다. 이어서 client가 보낸 동명 header를 사용하지 않고 oauth2-proxy 결과와 Nginx 환경의 internal token으로 /edge/me 요청을 새로 조립한다. Spring controller가 user header와 internal token을 함께 확인해 identity JSON을 만들고 Nginx가 브라우저에 전달한다.</desc>
