Antigravity Agent e9cbf23ab5 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.

CSharp Identifiers

🎯 한 줄 통찰 (One-line insight)

C#'s identifier rules (letters/digits/underscore, must start with letter/underscore, case-sensitive, no reserved words) are the same rule-set every C-family language in this series has used verbatim — the interesting detail isn't the rule itself but the STYLE convention layered on top: C# explicitly recommends lowercase-starting names (camelCase, e.g. minutesPerHour), which will matter later when C#'s method/class names are shown starting with an UPPERCASE letter (PascalCase) — a naming-convention split by identifier kind that C and C++ never enforced this explicitly. [S1]

🧠 핵심 개념 (Core concepts)

  • Identifier — the unique name given to a variable. [S1]
  • Character rules — letters, digits, and underscore (_) allowed; must begin with a letter or underscore (never a digit). [S1]
  • Case sensitivitymyVar and myvar are distinct variables. [S1]
  • No whitespace — names cannot contain spaces. [S1]
  • No reserved words — C# keywords like int or double cannot be used as identifier names. [S1]
  • Style convention (recommended, not enforced) — start with a lowercase letter; prefer descriptive names (minutesPerHour) over terse ones (m) for readability and maintainability. [S1]

📖 세부 내용 (Details)

  • Good vs. acceptable naming contrast: int minutesPerHour = 60; // Good vs int m = 60; // OK, but not so easy to understand. [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

  • 명명 규칙 자체는 C/C++/Java와 동일: 문자/숫자/언더스코어, 숫자로 시작 불가, 대소문자 구분, 예약어 사용 불가라는 규칙이 이전 언어들과 동일함이 확인됨 — 차이는 규칙이 아니라 스타일 권장(lowercase 시작, 서술적 이름 선호)에 있음. [S1]

🛠️ 적용 사례 (Applied in summary)

현재 발견된 실제 적용 사례가 없습니다 — minutesPerHour vs m 이름 비교가 원문에서 스타일 예제로 제시됨. [S1]

💻 코드 패턴 (Code patterns)

Descriptive vs. terse identifier naming (C#):

// Good
int minutesPerHour = 60;
// OK, but not so easy to understand what m actually is
int m = 60;
