ci: enable workflow dispatch for deploy

과거 실수들을 명시하여 같은 오류 반복 방지

## 실수 방지 체크리스트 추가

1. 카테고리 할당 실수 (category_id NULL)
2. 내용 길이 부족 (1,500자 미만)
3. 테이블 사용 금지 (리스트만)
4. 계산 예시 누락 (절세액 미수치)
5. 카테고리 주제 불일치
6. 정확한 세법 인용 누락

## 각 실수별
- 과거 오류 상황
- 문제점 분석
- 예방책 (SQL/마크다운 예시)
- 최종 체크리스트

SQL 확인 쿼리도 포함하여 DB 적용 후
자동 검증 가능하게 구성.

+
+## 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?
+```
+
+---
+
+## 카테고리 필수 규칙
+
+**모든 블로그 포스트는 반드시 하나의 카테고리에 할당되어야 합니다. (NOT NULL)**
+
+### 카테고리별 포스트 배치
+
+| 카테고리 | 최소 포스트 | 주제 범위 |
+|---------|-----------|---------|
+| 사업자 세무 | 3개 | 기장, 세무신고, 부가세, 종합소득세 |
+| 부동산 세금 | 3개 | 월세, 양도세, 상속세(부동산) |
+| 종합소득세 | 3개 | 프리랜서, 부업, 경비 처리 |
+| 부가가치세 | 3개 | 신고, 기한, 간이과세 vs 일반과세 |
+| 가족자산·증여 | 3개 | 자녀 증여, 상속, 자산 이전 |

+
+### 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

+## 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

+**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.

+## ⚠️ 실수 방지 체크리스트 (과거 오류 기록)
+
+**이전에 반복된 실수들을 기록하여, 같은 실수를 하지 않도록 합니다.**
+
+### 1️⃣ 카테고리 할당 실수 ❌
+
+**과거 오류**: 포스트를 만들 때 category_id를 NULL로 두었음
+
+**문제점**:
+- DB NOT NULL 제약 위반
+- 블로그 페이지에 노출 안 됨
+- 고객이 카테고리로 검색 불가
+
+**예방책**:
+- ✅ **SQL INSERT 시 반드시 category_id 명시**
+- ✅ **포스트 작성 전에 카테고리 결정**
+- ✅ **DB 적용 후 category_id NOT NULL 확인**
+- ✅ **각 카테고리별 최소 3개 이상 포스트 유지**
+
+**SQL 예시** (권장):
+```sql
+INSERT INTO blog_posts (title, slug, content, category_id, is_published, ...)
+VALUES ('제목', 'slug', $$본문$$, 1, true, ...);
+-- category_id 절대 생략 금지!
+```
+
+---
+
+### 2️⃣ 내용 길이 부족 ❌
+
+**과거 오류**: 에이전트가 지침(1,500~2,500자)을 무시하고 간단한 버전(500자)으로 생성
+
+**문제점**:
+- 고객 설득력 부족
+- 계산 예시 없음
+- 3단계 구조 불완전
+- 세법 인용 부족
+
+**예방책**:
+- ✅ **각 포스트 최소 1,500자 이상 (추천 2,000~2,500자)**
+- ✅ **포스트 작성 후 글자 수 확인: `LENGTH(content) >= 1500`**
+- ✅ **항상 실제 사례 포함** (이름, 나이, 직업, 구체적 상황)
+- ✅ **항상 계산 과정 포함** (절세액 수치화)
+- ✅ **3단계 구조 필수** (1️⃣ 기초 → 2️⃣ 현실 → 3️⃣ 해결책)
+
+**확인 쿼리**:
+```sql
+SELECT id, title, LENGTH(content) as length FROM blog_posts
+WHERE LENGTH(content) < 1500;  -- 부족한 포스트 검출
+```
+
+---
+
+### 3️⃣ 테이블 사용 금지 ❌
+
+**과거 오류**: 마크다운 테이블(`| |---|---|`) 사용
+
+**문제점**:
+- 지침 위반 (리스트만 사용)
+- 모바일에서 가독성 저하
+- 유지보수 어려움
+
+**예방책**:
+- ✅ **테이블 금지, 리스트만 사용** (- 또는 숫자 목록)
+- ✅ **작성 후 `| |` 패턴 검색으로 테이블 확인**
+- ✅ **수치/계산은 리스트 형식**:
+
+**❌ 금지 (테이블)**:
+```markdown
+| 항목 | 월 | 연간 |
+|------|-----|------|
+| 월세 | 150만 | 1,800만 |
+```
+
+**✅ 권장 (리스트)**:

+월 경비 구성:
+- 월세: 150만 원 (연 1,800만 원)
+- 재료비: 180만 원 (연 2,160만 원)
+- 직원급여: 100만 원 (연 1,200만 원)
+```
+
+---
+
+### 4️⃣ 계산 예시 누락 ❌
+
+**과거 오류**: 포스트에 개념만 있고 실제 계산 예시 부족
+
+**문제점**:
+- 고객이 "내 상황에 얼마나 해당하나" 판단 어려움
+- 추상적 설명으로 설득력 감소
+- 세무사 필요성 전달 미흡
+
+**예방책**:
+- ✅ **모든 포스트에 구체적 계산 예시 필수**
+- ✅ **절세액을 수치로 제시** ("약 50만 원 절약")
+- ✅ **단계별 계산 과정 포함** (Step 1️⃣, 2️⃣, 3️⃣, 4️⃣)
+- ✅ **실제 사례로 숫자 구체화**:

+
+### 5️⃣ 카테고리 주제 불일치 ❌
+
+**과거 오류**: 포스트 주제와 카테고리가 맞지 않음
+
+**문제점**:
+- 고객이 원하는 정보 검색 불가
+- 카테고리 신뢰도 저하
+- UX 혼란
+
+**예방책**:
+- ✅ **포스트 작성 전 카테고리 명확히 결정**
+- ✅ **포스트 주제와 카테고리 일관성 검증**:
+
+| 포스트 | 카테고리 | 확인 |
+|--------|---------|------|
+| 프리랜서 경비 | 종합소득세 (3) | ✅ 맞음 |
+| 월세 신고 | 부동산 세금 (2) | ✅ 맞음 |
+| 자녀 증여세 | 가족자산·증여 (5) | ✅ 맞음 |
+| 사업자 기장 | 사업자 세무 (1) | ✅ 맞음 |
+| 부가세 신고 | 부가가치세 (4) | ✅ 맞음 |
+
+---
+
+### 6️⃣ 정확한 세법 인용 누락 ❌
+
+**과거 오류**: 일부 포스트에서 법조 명시 부족
+
+**문제점**:
+- 정확성 원칙 위반
+- 법적 책임 불명확
+- 고객 신뢰도 저하
+
+**예방책**:
+- ✅ **모든 주요 내용에 세법 조항 인용 필수**
+- ✅ **형식**: "소득세법 제XX조에 따르면"
+- ✅ **연도 기준 명시**: "2025년 기준"
+- ✅ **포스트 끝에 "법적 근거" 섹션 필수**:
+
+```markdown
+**법적 근거**:
+- 소득세법 제29조 (수입금액의 계산)
+- 국세기본법 제47조 (가산세)
+- 소득세법 제160조 (증빙 보관)
+```
+
+---
+
+## ✅ 포스트 최종 체크리스트
+
+모든 포스트를 DB에 등록하기 전에 다음을 확인하세요:
+
+- [ ] **카테고리 할당**: `category_id NOT NULL` (필수)
+- [ ] **내용 길이**: `LENGTH(content) >= 1500` (최소 1,500자)
+- [ ] **테이블 확인**: `| |` 패턴 없음 (리스트만)
+- [ ] **계산 예시**: Step 1️⃣~4️⃣ 포함 (절세액 수치)
+- [ ] **세법 인용**: 모든 주요 내용에 법조 명시
+- [ ] **카테고리 일치**: 포스트 주제 ↔ 카테고리 일관성
+- [ ] **3단계 구조**: 1️⃣ 기초 → 2️⃣ 현실 → 3️⃣ 해결책
+- [ ] **광고 규칙**: 금지 표현(보장, 최저가, 무료) 없음
+- [ ] **사례 포함**: 실제 상황 + 이름/나이/직업 구체화
+- [ ] **정확성**: 추측/예상/의견 표현 없음
+
+**체크 쿼리**:
+```sql
+-- DB 적용 후 확인
+SELECT id, title, LENGTH(content), category_id
+FROM blog_posts
+WHERE LENGTH(content) < 1500 OR category_id IS NULL
+ORDER BY id;

+## WBS-UX-03 FAQ 관리 (어드민 CRUD)
+
+목표: 세무사가 관리자 화면에서 FAQ 항목을 직접 등록·수정·삭제·순서 조정한다.
+홈페이지 FAQ가 하드코딩에서 DB 기반으로 전환되어, 코드 수정 없이 운영 가능해진다.
+
+설계 방향:
+- FAQ 항목: 질문(question), 답변(answer), 정렬 순서(sort_order), 활성화 여부(is_active)
+- 홈페이지는 is_active=TRUE 항목을 sort_order 오름차순으로 표시
+- 카테고리 태그(선택): "기장·세금신고", "부동산", "증여·상속", "기타" — 홈페이지에서 탭 필터 가능
+
+성공 기준:
+- 관리자 `/taxbaik/admin/faqs` 목록/생성/수정/삭제/순서변경 동작
+- 홈페이지 FAQ 섹션이 DB에서 로드 (하드코딩 제거)
+- 비활성 항목은 홈페이지 미표시
+- sort_order 기준 정렬
