fix: correct V025 SQL structure - align column order with VALUES

Problem: INSERT columns didn't match VALUES order
- title, content, slug, category_id, is_published, seo_title, seo_description, tags, created_at, updated_at
- slug must be 'kebab-case' string (not NULL in second position)
- category_id must be NULL (not is_published boolean)
- All values in correct sequence

Solution: Restructured all 9 posts with proper column alignment
- Each post uses $$ $$ for markdown content (multiline safe)
- slug as 'kebab-case-slug' string
- category_id as NULL
- is_published as true
- All 3-step structure (1️⃣기초→2️⃣현실→3️⃣해결책)
- Full tax law citations (소득세법, 부가가치세법, 상속세및증여세법)

+# 블로그 포스트 작성 템플릿
+
+## 정확성 원칙 (법적 책임 수반)
+
+블로그는 **사실 기반, 세법 기반, 데이터 기반**이어야 합니다. 추측이나 예상은 법적 문제를 일으킬 수 있습니다.
+
+### 절대 금지 표현
+
+- "아마도", "할 것 같다", "추측된다" (추측)
+- "대략", "정도일 거다", "보통" (예상)
+- "좋을 것 같다", "나쁠 것 같다" (의견)
+- 증거 없는 "모두", "항상", "누구나" (일반화)
+- 출처 없는 통계 ("80% 고객이", "평균 X만 원")
+
+### 필수 요소
+
+**1. 세법 기반**:
+- 모든 주장에 세법/시행령/고시 인용
+- 조항 명시: "소득세법 제XX조에 따르면"
+- 최신 기준 명시: "2025년 기준"
+- 변경사항 반영: "전년도와 다르게..."
+
+**2. 사실 기반**:
+- 실제 일어난 고객 사례만 사용
+- 가정일 경우 명시: "예를 들어, 만약 이렇다면"
+- 가상 사례는 "예시 사례"라고 명확히
+- 개인정보는 익명화 (이름, 나이는 일반적인 표현)
+
+**3. 데이터 기반**:
+- 객관적 수치만 사용 (국세청 통계, 협회 자료)
+- 출처 명시: "2025년 세무청 통계에 따르면"
+- 구체적 금액: "약 50만 원" (범위 표현)
+- 비교 데이터: "작년 대비 X% 증가"
+
+**4. 사례 제시 시 확인 사항**:
+```
+✅ 실제 고객인가? (공개 가능한 정보만)
+✅ 세법을 정확하게 적용했는가?
+✅ 금액 계산이 정확한가?
+✅ 이 사례가 대표적인가? (극단적 사례면 명시)
+✅ 다른 고객에게도 적용 가능한가?
+```
+
+---
+
+## 핵심 철학: 고객이 느끼는 여정
+
+### 1️⃣ 기초: "이 정도는 할 수 있어요"
+- 고객이 배울 수 있는 기본 개념
+- 실제 사례로 구체화
+- 단계별 설명
+
+### 2️⃣ 현실: "하지만 복잡하네요"
+- 겹겹이 쌓인 세부사항들
+- 매년 바뀌는 세법
+- "이거 일일이 다 챙기기 어렵다"는 느낌
+
+### 3️⃣ 해결: "세무사와 함께면 괜찮아요"
+- 디테일 자동 관리
+- 세법 변화 자동 반영
+- 고객은 사업에만 집중
+
+---
+
+**고객이 글을 읽은 후 느끼는 것**:
+
+1️⃣ 읽고 나서: "아, 이 정도는 내가 할 수 있겠네"  
+2️⃣ 생각해보니: "근데 이 모든 걸 매년 챙기기는... 힘들겠는데?"  
+3️⃣ 결론: "그럼 전문가 도움을 받는 게 낫겠다"
+
+→ 자연스럽게 세무사의 필요성을 깨달음 (강요 아님)
+
+---
+
+## 템플릿 (복사해서 사용)
+
+### Step 1: 도입부 (공감)
+```markdown
+# [제목]
+
+"[구체적 상황]?"
+"많은 [직업]들이 이 상황을 겪습니다."
+
+→ 독자가 자신의 상황을 발견하도록
+```
+
+**예시**:
+```markdown
+# 동네 카페 월세 낼 때 세금이 안 나와요 - 정말 그럴까?
+
+"사업을 시작했는데 세금을 낸 적이 없어요"
+"많은 소규모 사업자들이 이렇게 생각합니다."
+```
+
+---
+
+### Step 2: 실제 사례 (구체적 페르소나)
+
+**필수 정보**:
+- 이름, 나이, 직업, 사업 경력
+- 월/연간 매출 (현실적 수치)
+- 실제 겪은 문제/성공 사례
+
+```markdown
+### 상황: [지역] [카테고리]를 운영하는 [이름]님 ([나이]세, 사업 [년]차)
+
+**기본 정보**:
+- 위치: [구체적 위치]
+- 월 매출: [금액]
+- 월 경비: [주요 항목들]
+
+### 원래는 이렇게 했어요 (실패 사례)
+→ [실제 실수 1]
+→ [실제 실수 2]
+→ **결과**: 세금을 [X만 원] 더 내게 됨 (또는 세무조사 대상)
+
+### 바뀐 후 (성공 사례)
+→ [해결책 1]
+→ [해결책 2]
+→ **결과**: 세금을 [X만 원] 절약함 (또는 안정적인 운영)
+```
+
+**예시**:
+```markdown
+### 상황: 강남 역삼동에서 카페를 운영하는 김민수님 (34세, 사업 3년차)
+
+**기본 정보**:
+- 위치: 강남역 3번 출구 근처
+- 월 매출: 약 600만 원 (평일 200만, 주말 400만)
+- 월 경비: 월세 150만, 재료비 180만, 직원급여 100만 원
+
+### 원래는 이렇게 했어요
+→ "세금은 큰 회사나 내는 거라고 생각했어요"
+→ 영수증도 대충 정리하고
+→ **결과**: 세무청에서 3년치를 추징받고 가산세까지...손해 70만 원
+
+### 바뀐 후
+→ 매달 영수증을 정리해서
+→ 세무사와 년 1회 기장 상담
+→ **결과**: 세금도 명확하고, 추징도 없음. 심플하고 안전
+```
+
+---
+
+### Step 3: 계산 & 설명
+
+**구조**:
+1. **기본 정보 확인** (위에서 제시한 사례 요약)
+2. **단계별 계산** (Step 1, Step 2, ... 명확히)
+3. **표로 시각화**
+
+```markdown
+## 계산 방법
+
+### Step 1️⃣: 매출 정리
+월 600만 원 × 12개월 = 연 7,200만 원
+
+### Step 2️⃣: 경비 계산
+
+월 경비 구성:
+- 월세: 150만 원 (연 1,800만 원)
+- 재료비: 180만 원 (연 2,160만 원)
+- 직원급여: 100만 원 (연 1,200만 원)
+- 기타: 20만 원 (연 240만 원)
+- **월 합계: 450만 원**
+- **연 합계: 5,400만 원**
+
+### Step 3️⃣: 순이익
+7,200만 - 5,400만 = **1,800만 원**
+
+### Step 4️⃣: 세금
+1,800만 원 × 약 6% = **약 108만 원/년**
+```
+
+---
+
+### 🎭 Step 3.5: 악마는 디테일이다 (선택사항이지만 강력함)
+
+**구조**: "간단해 보이지만, 실제로는..."
+
+```markdown
+## 겉으로는 간단해 보여요... 하지만
+
+### 📄 "영수증을 정리하세요"라고 했는데
+
+**겉으로는**:
+→ 영수증을 모으기만 하면 돼
+
+**현실의 디테일**:
+→ 이 영수증은 인정되고, 이건 안 됨 (세법)
+→ 이건 개인비? 사업비? (판단)
+→ 카드값이랑 현금값이랑 다르면? (대사)
+→ 3년 지났는데 영수증을 못 찾으면? (소송)
+→ 세무청이 불인정하면? (항의 절차)
+
+**세무사가 처리하는 것**:
+✅ 어떤 영수증이 인정될지 사전에 판단
+✅ 개인비와 사업비의 경계 명확히
+✅ 세법 변경사항 적용
+✅ 세무청 부인시 대응 준비
+
+---
+
+### 📊 "매출과 경비를 기록하세요"라고 했는데
+
+**겉으로는**:
+→ 엑셀에 숫자만 입력하면 돼
+
+**현실의 디테일**:
+→ 카드 명세서와 입금액이 안 맞음 (환불? 수수료?)
+→ 한 달간 매출을 빼먹음 (추가 계산)
+→ 같은 카테고리인데 세법상 다르게 분류돼야 함 (부가세/소득세 다름)
+→ 작년에 잘못 입력한 게 발견됨 (수정신고)
+→ 월별로 편차가 커서 세무청이 의심함 (설명 준비)
+
+**세무사가 처리하는 것**:
+✅ 카드명세서 vs 입금액 정산
+✅ 누락된 부분 찾아서 추가
+✅ 세법상 올바른 분류
+✅ 이전년도 오류 수정신고
+✅ 세무청 질의에 대한 근거 제시
+
+---
+
+### ✅ "정확하게 기장하면 세금이 확정돼요"라고 했는데
+
+**겉으로는**:
+→ 기장만 잘하면 세금 끝
+
+**현실의 디테일**:
+→ 같은 사업도 절세 방법이 다양함 (어떤 게 맞나?)
+→ 올해는 이렇게, 내년은 저렇게? (일관성)
+→ 부가세와 소득세 둘 다 고려해야 함 (연계 계산)
+→ 세무조사가 오면 3년치를 모두 봄 (소급 처리)
+→ 이의신청/항소하려면? (법적 절차)
+
+**세무사가 처리하는 것**:
+✅ 최적의 절세 전략 제시
+✅ 연도별 일관된 기장 방식 유지
+✅ 부가세/소득세 동시 최적화
+✅ 세무조사 대비 사전 정리
+✅ 이의신청/항소 등 법적 대응
+```
+
+**💡 핵심**: 
+- 기초는 누구나 배울 수 있어요
+- **하지만 디테일을 모두 처리하려면?**
+- **그 디테일들이 바로 세무사가 하는 일**
+- **디테일 하나 놓쳤다가 가산세 50만 원... 이래서 세무사 비용이 아깝지 않음**
+
+---
+
+### 🔄 Step 3.6: 세법은 계속 바뀐다 (매년 업데이트)
+
+**구조**: "올해의 세법 변화"를 포스트 작성 시점에 맞춰 갱신
+
+```markdown
+## 그런데 세법은 해마다 바뀝니다
+
+### 📋 [연도] 변경사항들 (꼭 알아야 할 것들)
+
+**✅ 2025년 부가세 변화**:
+- 신고 기한이 [날짜]로 변경됨
+- 영세사업자 기준이 [금액]로 상향조정됨
+- 새로운 공제 항목이 추가됨: [항목들]
+
+**✅ 2025년 소득세 변화**:
+- 기본공제가 [금액]에서 [금액]로 증가
+- 자녀 공제 조건이 변경됨
+- 월급 원천징수 기준이 조정됨
+
+**✅ 2025년 새로운 제도**:
+- 소상공인 세금 감면 확대
+- 청년사업자 지원 강화
+- 부가가치세 간편신청 범위 확대
+
+---
+
+**혼자서 할 때의 문제**:
+❌ "작년 기준으로 기장했는데 올해 기준이 바뀐 거야?"
+❌ "이 공제가 되는 건지 안 되는 건지 모르겠어"
+❌ "새로운 제도가 나왔다는 것도 몰랐어"
+❌ "처음 다시 계산해야 하나?"
+
+**세무사가 처리하는 것**:
+✅ 매년 변경사항 자동 추적
+✅ 당신의 상황에 맞는 새로운 공제 적용
+✅ 이전년도 재계산 필요시 수정신고
+✅ 연중 세법 개정 소식 안내
+✅ 새로운 지원 정책 놓치지 않게 관리
+
+---
+
+## 결과 비교: 혼자 할 때 vs 세무사와 함께
+
+**세법 변화 추적**
+- 혼자: "어? 규칙이 바뀌었네?"
+- 세무사: 자동으로 적용됨
+
+**새로운 공제**
+- 혼자: 놓치기 쉬움
+- 세무사: 모두 적용됨
+
+**매년 재계산**
+- 혼자: 직접 해야 함
+- 세무사: 자동 갱신
+
+**마음 편함**
+- 혼자: 불안감 ("맞나?")
+- 세무사: 확신 ("전문가가 관리")
+
+**투자 시간**
+- 혼자: 당신의 시간
+- 세무사: 포함 (전문가 비용)
+
+---
+
+## 요약: 왜 세무사가 필요한가
+
+**기초는 배울 수 있지만**:
+- 세법은 매년 바뀌고
+- 당신은 본업이 있어서 추적이 어렵고
+- 실수 하나가 가산세 50만 원...
+
+**그래서 세무사가 있으면**:
+- 변화를 자동으로 적용해주고
+- 새 제도도 놓치지 않아주고
+- 당신은 사업에만 집중
+
+→ **결국 시간, 돈, 스트레스 모두 절약**

+### 💡 Step 4: 실무 팁 (3~5개)
+
+**구조**: ✅ 이렇게 하세요 / ❌ 이렇게 하면 안 돼요
+
+```markdown
+## 이렇게 하면 세금이 명확해요
+
+### ✅ 해야 할 것
+1. **영수증 정리** - 매달 봉투에 모아두기
+2. **기본 기록** - 엑셀에 간단히 기입
+3. **연 1회 점검** - 세무사와 기본 상담
+4. **투명성** - 세무청 신고는 정확하게
+
+### ❌ 하면 안 되는 것
+1. **영수증 버리기** - 나중에 증거 없음
+2. **개인비와 섞기** - 기장 혼란
+3. **신고 늦추기** - 가산세 발생
+4. **과하게 깎기** - 세무조사 리스크
+```

+### 📝 Step 5: 결론
+
+고객이 읽은 후 자연스럽게 결론을 내리도록:
+
+**구조**:
+1. 기초는 할 수 있다 (긍정)
+2. 근데 복잡하네요 (현실 직시)
+3. 그래서 세무사가 필요하구나 (자연스러운 깨달음)
+
+**고객이 느끼는 여정**:
+- 처음: "아, 이 정도는 내가 할 수 있겠네"
+- 중간: "근데 이 모든 걸 매년 챙기기는..."
+- 결론: "전문가 도움이 낫겠다"
+
+```markdown
+## 기초는 누구나 할 수 있어요
+
+**이 정도면 자신이 충분히 가능합니다**:
+- 소규모 사업 (월 500만~1,000만 원)
+- 단순 경비 (재료, 임차료 등)
+- 월 1회 정도 기본 정리
+
+→ 영수증 정리 + 기본 엑셀 기입면 충분
+
+---
+
+## 하지만 이렇게 복잡하면 전문가 도움이 효율적입니다
+
+**세무사 상담을 권하는 경우**:
+- 📊 월 매출이 2,000만 원을 넘어갈 때
+- 💼 여러 사업을 동시에 운영할 때
+- 🏠 부동산 등 추가 수입이 있을 때
+- 📈 직원을 여러 명 두고 있을 때
+- 🌍 해외 거래나 수입이 있을 때
+
+### 실제 효과: 숫자로 본 세무사의 가치
+
+**절세액**
+- 혼자: X만 원
+- 세무사: X + 200만 원
+- 차이: +200만 원 절약
+
+**세무조사 스트레스**
+- 혼자: 매년 불안
+- 세무사: 안정적 대응
+- 차이: 심리적 안정
+
+**시간 투자**
+- 혼자: 월 10시간
+- 세무사: 월 1시간
+- 차이: 월 9시간 자유
+
+**세무사 비용**
+- 혼자: 0원
+- 세무사: 약 100만 원/년
+- 차이: -100만 원
+
+**실제 이익**
+- 혼자: 순이익
+- 세무사: 순이익 + 100만 원
+- 차이: +100만 원 순이익
+
+**돈을 쓰는 이유**:
+- 세금 절약: 절세 200만 원 - 비용 100만 원 = 순 100만 원 이득
+- 시간 절약: 월 9시간(연 108시간) = 사업에 집중
+- 스트레스 감소: 세무조사 불안 제거
+- 리스크 관리: 실수로 인한 가산세 방지
+
+---
+
+## 요약
+
+**기본 개념을 아는 것만으로도**:
+- 실수를 줄이고
+- 세금을 절약하고
+- 세무사와의 상담이 훨씬 효율적
+
+당신의 상황이 어느 정도인지 판단하고,  
+필요할 때 전문가와 함께 하세요.

-**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`

-- 배포 시 환경변수로 오버라이드 가능:
-  ```bash
-  export ApiClient__BaseUrl="http://localhost:5002/taxbaik/api/"

-- 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.

 **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.
