-### UI 기준 원칙 (2026-06-29 추가)
-- 기본 디자인 템플릿은 `https://v5.fluentui-blazor.net/` 기준으로 한다.
-- 신규 또는 리팩토링 UI는 Fluent UI Blazor v5 패턴을 우선 적용한다.
-- MudBlazor는 레거시 폐기 대상이다. 새 UI나 리팩토링 UI에서는 사용하지 않는다.
-- 기존 MudBlazor 잔여 코드는 Fluent v5 또는 순수 HTML/CSS로 점진 전환한다.
-- 기본 로딩 상태는 `Skeleton`이다. `MudProgressCircular` / `MudProgressLinear`는 예외적으로만 사용한다.
-- `MudDataGrid`, `MudDialog`, `MudTabs`는 폐기 대상이다. 새 작업에서는 사용하지 말고 Fluent v5 또는 순수 HTML/CSS 패턴으로 대체한다.
-- 목록, 카드, 대시보드, 상세 페이지의 초기 데이터 상태는 스켈톤으로 먼저 렌더링하고, 데이터 수신 후 실제 UI로 교체한다.
-- 로딩 중 블로킹 스피너보다 스켈톤을 우선한다.
-- 관리자와 공개 사이트는 가능한 한 같은 `design-tokens.css` / `ui-primitives.css` 기반으로 구성한다.
-- Blazor 진입점은 중복 매핑하지 말고, 동일 호스트 내에서 라우트 충돌이 없도록 단일 엔트리 기준으로 구성한다.
-- `@page` 중복이나 동일 경로의 Razor Pages + Blazor 중복 선언은 배포 전에 반드시 제거한다.
-
-### 레거시 정책
-- MudBlazor, MudDataGrid, MudDialog, MudTabs는 신규 도입 금지다.
-- 남아 있는 레거시 UI는 우선순위에 따라 Fluent v5 또는 순수 HTML/CSS로 교체한다.

-**표준 배포 (현재)**:
-1. `master` 브랜치에 push
-2. Gitea Actions가 `TaxBaik.Web`을 build/publish
-3. CI가 서버의 `taxbaik` 서비스와 `~/taxbaik_active`를 갱신
-4. CI가 서비스 재시작 후 `/taxbaik/admin/login`으로 헬스 체크
-
-**API 클라이언트 설정 (Green-Blue 대비)**:
-- API 클라이언트 Base URL이 이제 동적 설정됨: `appsettings.json` > `ApiClient:BaseUrl`
-- 기본값: `http://localhost:5001/taxbaik/api/`
-- 배포 시 환경변수로 오버라이드 가능:
-  ```bash
-  export ApiClient__BaseUrl="http://localhost:5002/taxbaik/api/"
-  systemctl start taxbaik  # 새 포트에 배포
-  ```
-- Nginx가 `/taxbaik` → active 포트로 라우팅하면 자동 전환됨
+**무중단 Green-Blue 배포 아키텍처 (2026-06-30 적용 완료)**:
+1. **프록시 레이어**: 포트 `5001`에서 영구 가동되는 초경량 .NET TCP 프록시([TaxBaik.Proxy])가 수신 대기합니다. Nginx는 `/taxbaik` 트래픽을 기존과 같이 `5001`로 중계합니다.
+2. **동적 포트 스위칭**: 프록시는 요청이 들어올 때마다 `/home/kjh2064/taxbaik_port` 파일을 읽어 active 포트(5003 또는 5004)를 판단하고 트래픽을 포워딩합니다.
+3. **배포 흐름 (`deploy_gb.sh`)**:
+   - Gitea Actions가 코드를 build/publish 후 압축하여 서버에 업로드합니다.
+   - 서버의 배포 스크립트([deploy_gb.sh])가 실행되어 현재 미사용 중인 예비 포트(Target Port: 5003 또는 5004)를 파악합니다.
+   - 예비 포트에서 새 .NET 웹 앱을 실행하고 `http://127.0.0.1:$target_port/taxbaik/healthz` 헬스 체크를 통과할 때까지 폴링(최대 60초)합니다.
+   - 헬스 체크 성공 시 `/home/kjh2064/taxbaik_port` 파일에 새 포트 번호를 기입하여 **트래픽을 즉시 무중단 전환**합니다.
+   - 기존 포트에서 동작하던 구버전 .NET 프로세스를 종료(`kill -15`)합니다.
+   - 만약 헬스 체크 실패 시 새 프로세스만 강제 종료하고 배포를 롤백하여 실서비스 다운타임을 방지합니다.
 
 **운영 규칙**:
-- 로컬 또는 서버에서 수동 `dotnet publish`로 운영 배포하지 않는다
-- `rsync`로 직접 아티팩트를 올리지 않는다
-- 배포 실패 시 CI 로그를 먼저 본다
-- 배포된 아티팩트는 CI가 만든 것만 신뢰한다
-- 배포 후 검증은 홈, 관리자 로그인 페이지, 로그인 API를 모두 포함한다
+- 로컬 또는 서버에서 수동 `dotnet publish`로 운영 배포하지 않는다.
+- 배포 실패 시 Gitea Actions CI/CD 로그 및 `~/deployments/taxbaik_timestamp/web_*.log`를 먼저 확인한다.
+- 배포 후 최종 검증은 프록시 포트를 경유하는 메인 홈페이지, 관리자 로그인 페이지, 로그인 API를 모두 포함한다.
 
 **롤백**:
-- 이전 정상 커밋을 `master`에 revert 또는 hotfix로 되돌린다
-- 서버 파일을 수동으로 복구하지 않는다
-- 롤백은 커밋 단위로 추적 가능해야 한다
+- 이전 정상 커밋을 `master`에 revert 또는 hotfix로 되돌려 다시 배포를 수행하거나, 비상시 서버의 `taxbaik_port` 파일의 포트 번호를 수동 수정하여 이전 버전 포트로 즉시 원상복구한다.
