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)

C Comments

🎯 한 줄 통찰 (One-line insight)

Before C99 (1999), single-line // comments were NOT part of standard C at all — only /* */ multi-line comments existed — meaning // comments, now the default choice for short notes, are actually a relatively recent addition to the language's ~50-year history, not an original feature. [S1]

🧠 핵심 개념 (Core concepts)

  • Single-line comments (//) — everything from // to the end of the line is ignored by the compiler. [S1]
  • Multi-line comments (/* */) — everything between the markers is ignored, regardless of line count. [S1]
  • Comments as code-disabling tool// can be prefixed to a line of working code to temporarily disable it during testing, without deleting it. [S1]
  • Historical constraint — pre-C99, only /* */ was valid; // support was added in the C99 standard. [S1]

📖 세부 내용 (Details)

  • Single-line comment before code: // This is a comment followed by printf("Hello World!");. [S1]
  • Single-line comment disabling code: printf("This will run"); // printf("This will NOT run");. [S1]
  • Multi-line comment: /* The code below will print the words Hello World! to the screen, and it is amazing */ printf("Hello World!");. [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

  • // 주석의 표준화 시점: C99(1999) 이전에는 다중 줄 주석(/* */)만 사용 가능했고, 한 줄 주석(//)은 C99부터 표준에 포함되었다는 역사적 사실이 명시됨 — 구형 컴파일러/표준 준수 코드 작성 시 유의해야 할 사항. [S1]

🛠️ 적용 사례 (Applied in summary)

현재 발견된 실제 적용 사례가 없습니다 — 특정 코드 줄을 지우지 않고 // 로 임시 비활성화하는 것이 실전 디버깅/테스트에서 흔히 쓰이는 기법이다. [S1]

💻 코드 패턴 (Code patterns)

Temporarily disabling a line of code using a single-line comment instead of deleting it (C):

printf("This will run");
// printf("This will NOT run");
