+- 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.

+### CI Deploy 트러블슈팅 하네스 (2026-06-28)
+
+커밋 후 배포가 동작하지 않는다고 판단하기 전에 아래 순서로 확인한다. 추측으로 runner, secret, 커밋 제목을 원인으로 단정하지 않는다.
+
+1. **푸시 결과 확인**
+   ```powershell
+   git push origin master 2>&1 | Select-String "master|To|Processed|remote"
+   ```
+   `master -> master`가 보이면 Git push는 성공이다. 이 단계는 CI 실행 성공을 의미하지 않는다.
+
+2. **Actions run 생성 확인**
+   ```powershell
+   $headers = @{ Authorization = "token $env:GITEA_TOKEN_TAXBAIK" }
+   $runs = Invoke-RestMethod -Headers $headers -Uri "http://178.104.200.7/api/v1/repos/kjh2064/taxbaik/actions/runs?limit=10"
+   $runs.workflow_runs | Select-Object id,path,event,head_sha,display_title,status,conclusion
+   ```
+   `deploy.yml@refs/heads/master`, `event=push`, 최신 `head_sha`가 있어야 배포가 실제로 시작된 것이다.
+
+3. **workflow 파싱 검증**
+   ```powershell
+   curl.exe -sS -w "`nHTTP_STATUS:%{http_code}`n" `
+     -H "Authorization: token $env:GITEA_TOKEN_TAXBAIK" `
+     -H "Content-Type: application/json" `
+     -X POST "http://178.104.200.7/api/v1/repos/kjh2064/taxbaik/actions/workflows/deploy.yml/dispatches?return_run_details=true" `
+     --data '{"ref":"refs/heads/master","inputs":{}}'
+   ```
+   `failed to unmarshal workflow content`가 나오면 `.gitea/workflows/deploy.yml` YAML 문법 문제다. 여러 줄 문자열은 반드시 `run: |` 블록 들여쓰기 안에 둔다.
+
+4. **job 실패 로그 확인**
+   ```powershell
+   curl.exe -sS -H "Authorization: token $env:GITEA_TOKEN_TAXBAIK" `
+     "http://178.104.200.7/api/v1/repos/kjh2064/taxbaik/actions/jobs/{job_id}/logs"
+   ```
+   빌드/테스트/배포/헬스체크 중 어느 단계인지 먼저 분리한다.
+
+**이번 장애 원인 기록**:
+- `deploy.yml`의 Telegram 여러 줄 메시지 일부가 YAML 블록 들여쓰기 밖에 있어 Gitea workflow 파서가 실패했다.
+- 이후 배포 실행은 되었지만, 운영 `Authentication:*:ClientId`가 빈 값인데 OAuth provider를 무조건 등록해 `ClientId` 예외로 500이 발생했다.
+- 외부 OAuth provider는 ClientId/ClientSecret이 모두 있을 때만 등록한다.
