Antigravity Agent c24165b8bc refactor(topics): 멀티 에이전트용 지식 재편 — _Common(공통 기본기) + Domain_* 구조
에이전트 8종(대화형/프로그래머 C·S/디자이너/설계자/기획자/QA/PD/PM)에게
[공통 기본 능력 + 롤별 Specialty] 2층으로 지식을 주입하기 위한 재분류.
문서 내용·포맷은 무수정, 폴더 이동만 (6,372개 문서 수 보존 확인).

- Topic_Programming → Domain_Programming (내부 구조 보존)
- Topic_Graphic → Domain_Design
- Topic_Business → Domain_Product
- Topic_General → Domain_General
- _Common 신설: Math(구 Topic_Math_Specialty), Reasoning(구 General/From_Thinking & Reasoning),
  Reasoning_Creativity(구 General/From_창의성), Communication(Poetic_Blog_Writing + From_writing)
- 타 도메인의 From_* 폴더는 유지 (출처 표기일 뿐, 이미 도메인에 맞게 분류된 문서)
- 빈 폴더 정리 (memory/procedures)
- 에이전트→폴더 매핑은 workspace의 .astra/agent-knowledge-map.json (9개 에이전트)

CSharp Switch

🎯 한 줄 통찰 (One-line insight)

The switch(expression) { case x: ... break; default: ... break; } skeleton is structurally identical to C/C++'s switch statement — same case/break/default keywords, same "evaluate once, compare against each case" model — making Switch the fourth chapter in the C# series (after Comments, Operators, Special Characters) where the answer to "what's different from C++" is essentially nothing at the syntax level shown here. [S1]

🧠 핵심 개념 (Core concepts)

  • switch(expression) — evaluated exactly ONCE, then compared against each case value in order. [S1]
  • case x: — if the switch expression matches x, that block's code runs. [S1]
  • break — exits the switch block immediately once a match's code has run, preventing execution from continuing into subsequent cases; described as saving execution time by skipping the rest of the block. [S1]
  • default: — optional; runs when NO case matches the expression. [S1]

📖 세부 내용 (Details)

  • Weekday-name example: switch (day) { case 1: Console.WriteLine("Monday"); break; ... case 7: Console.WriteLine("Sunday"); break; } with day = 4 → outputs "Thursday". [S1]
  • Default fallback example: switch (day) { case 6: ...Saturday...; break; case 7: ...Sunday...; break; default: Console.WriteLine("Looking forward to the Weekend."); break; } with day = 4 (no matching case) → outputs "Looking forward to the Weekend." via default. [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

  • switch 구조가 C/C++와 동일: switch/case/break/default 키워드와 전체 구조가 C/C++의 switch문과 차이가 없다는 점이 확인됨 — Comments, Operators, Special Characters에 이은 네 번째 "구조 동일" 챕터. [S1]

🛠️ 적용 사례 (Applied in summary)

요일 번호(day)를 받아 요일 이름을 출력하는 switch문과, 매치되는 case가 없을 때 default로 넘어가는 예제가 원문에서 직접 실전 활용 사례로 제시됨. [S1]

💻 코드 패턴 (Code patterns)

Switch with break and default (C#):

int day = 4;
switch (day)
{
    case 1:
        Console.WriteLine("Monday");
        break;
    case 4:
        Console.WriteLine("Thursday");
        break;
    default:
        Console.WriteLine("Looking forward to the Weekend.");
        break;
}
// Outputs "Thursday"
