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 Special Characters

🎯 한 줄 통찰 (One-line insight)

Every escape sequence in this chapter (\', \", \\, \n, \t, \b) is character-for-character identical to C and C++'s escape sequences, making this the third "zero divergence" chapter in the C# series so far (after Comments and Operators) — the pattern across all three is that C#'s LEXICAL-LEVEL syntax (tokens, literals, comments, escapes) stays fully compatible with the C family, while its STRUCTURAL rules (mandatory classes, .Length as property not method, Convert.To*) are where the real divergence happens. [S1]

🧠 핵심 개념 (Core concepts)

  • Why escapes are needed — a double quote inside a double-quoted string literal breaks parsing; C# needs a way to include one. [S1]
  • \' — inserts a single quote. [S1]
  • \" — inserts a double quote. [S1]
  • \\ — inserts a single backslash. [S1]
  • \n — new line. [S1]
  • \t — tab. [S1]
  • \b — backspace. [S1]

📖 세부 내용 (Details)

  • Broken (unescaped) example shown deliberately as an error case: string txt = "We are the so-called "Vikings" from the north."; — the tutorial shows this fails, then fixes it with \". [S1]
  • Fixed: string txt = "We are the so-called \"Vikings\" from the north.";. [S1]
  • Single quote escape: string txt = "It\'s alright.";. [S1]
  • Backslash escape: string txt = "The character \\ is called backslash.";. [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

  • 이스케이프 시퀀스가 C/C++와 완전히 동일: \' \" \\ \n \t \b 전부 C/C++와 기호·의미가 동일하다는 점이 확인됨 — Comments, Operators에 이은 세 번째 "완전 동일" 챕터. 이는 C#의 어휘 수준 문법(토큰/리터럴/주석/이스케이프)이 C 계열과 완전히 호환되는 반면, 구조적 규칙(클래스 강제, .Length 프로퍼티, Convert.To* 등)에서만 실질적으로 갈라진다는 패턴을 보여줌. [S1]

🛠️ 적용 사례 (Applied in summary)

현재 발견된 실제 적용 사례가 없습니다 — 큰따옴표/작은따옴표/백슬래시를 이스케이프해 문자열에 포함시키는 예제가 원문에서 제시됨. [S1]

💻 코드 패턴 (Code patterns)

Escape sequences — identical to C/C++ (C#):

string txt1 = "We are the so-called \"Vikings\" from the north.";
string txt2 = "It\'s alright.";
string txt3 = "The character \\ is called backslash.";
