docs(10_Wiki): Dev 폴더 누락분 반영 — Topic_Programming으로 통합

이전 재구성 작업에서 Dev/ 폴더가 누락되었던 것을 반영.

- Dev/Topic_Programming(중첩 폴더, 78개)은 Dev 자체 최상위 폴더들
  (Architecture/Conventions/Engineering_Intelligence 등)과 완전 중복이라 제거.
- Dev 최상위 엔지니어링 지식 폴더(Architecture/Conventions/Engineering_Intelligence/
  Failure_Library/Generalized_Principles/Language/Pattern_Catalog/Platform_Guides/
  Subsystems, 77개)는 이미 Topic_Programming/Topic_Programming에 더 최신 버전이
  존재해 중복 제거(고유 콘텐츠 1개는 예외 처리하여 이동 보존).
- Dev의 W3Schools 언어 튜토리얼 폴더(Topic_C/CPP/CSS/CSharp/HOWTO/HTML/Java/
  JavaScript/PHP/Python/SQL/W3CSS, 1201개)는 전부 Topic_Programming 하위로 이동.
- 에이전트 운영 상태(.astra/docs)는 그대로 유지, 콘텐츠 폴더만 정리.
- Topic_Programming 최종 문서 수: 2784 → 3985.

+# [[SQL Between]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+BETWEEN selects values within an inclusive range — numbers, text (alphabetical range), or dates — and can be negated with NOT BETWEEN or combined with IN. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **BETWEEN operator** — selects values within a specified range; the range is inclusive of both boundary values. [S1]
+- **Syntax** — `SELECT column_name(s) FROM table_name WHERE column_name BETWEEN value1 AND value2;`. [S1]
+- **NOT BETWEEN** — selects values outside the specified range. [S1]
+- **Value types** — works with numbers, text (alphabetical ordering), and dates. [S1]
+
+## 🧩 추출된 패턴 (Extracted patterns)
+- **BETWEEN + IN combo** — `WHERE Price BETWEEN 10 AND 20 AND CategoryID IN (1,2,3);` layers a range filter with a set-membership filter. [S1]
+- **Date format discipline** — date BETWEEN comparisons require the literal format to match the database's date format convention (e.g. `'YYYY-MM-DD'`). [S1]
+
+## 📖 세부 내용 (Details)
+- Numeric range: `SELECT * FROM Products WHERE Price BETWEEN 10 AND 20;`. [S1]
+- Negated numeric range: `WHERE Price NOT BETWEEN 10 AND 20;`. [S1]
+- Text (alphabetical) range: `WHERE ProductName BETWEEN 'Geitost' AND 'Louisiana Hot Spiced Okra' ORDER BY ProductName;`. [S1]
+- Date range: `WHERE OrderDate BETWEEN '1996-07-01' AND '1996-07-31';` selects orders placed in July 1996. [S1]
+
+## ⚖️ 모순 및 업데이트 (Contradictions & updates)
+소스에서 모순되는 정보는 발견되지 않음.
+
+## 🛠️ 적용 사례 (Applied in summary)
+현재 발견된 실제 적용 사례가 없습니다 — 가격 범위 필터, 날짜 범위 리포트 등 실무 쿼리에서 흔히 재사용되는 패턴이다. [S1]
+
+## 💻 코드 패턴 (Code patterns)
+Numeric range (SQL):
+```sql
+SELECT * FROM Products
+WHERE Price BETWEEN 10 AND 20;
+```
+Date range (SQL):
+```sql
+SELECT * FROM Orders
+WHERE OrderDate BETWEEN '1996-07-01' AND '1996-07-31';
+```
