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)

Python Variables

🎯 한 줄 통찰 (One-line insight)

Python variables need no declaration or fixed type — a variable is created on first assignment and can be reassigned to a completely different type later, with type() always available to check its current type. [S1]

🧠 핵심 개념 (Core concepts)

No declaration keyword — a variable is created the moment a value is first assigned to it. [S1]
Dynamically typed — variables aren't bound to a type and can change type after being set. [S1]
Casting — str(), int(), float() explicitly specify a variable's data type. [S1]
type() function — returns a variable's current data type. [S1]
Quote flexibility — string variables can use single or double quotes interchangeably. [S1]
Case sensitivity — variable names are case-sensitive (a and A are different variables). [S1]

🧩 추출된 패턴 (Extracted patterns)

Type can change mid-program — x = 4 (int) then x = "Sally" (str) is legal; the variable simply now refers to a different type of object. [S1]

📖 세부 내용 (Details)

Basic creation: x = 5; y = "John". [S1]
Type change: x = 4 # int then x = "Sally" # str. [S1]
Casting: x = str(3); y = int(3); z = float(3). [S1]
Get type: print(type(x)). [S1]
Case sensitivity: a = 4; A = "Sally" creates two distinct variables. [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

소스에서 모순되는 정보는 발견되지 않음.

🛠️ 적용 사례 (Applied in summary)

현재 발견된 실제 적용 사례가 없습니다 — Data Types/Casting 챕터에서 이 개념이 더 깊이 다뤄진다. [S1]

💻 코드 패턴 (Code patterns)

Dynamic typing and casting (Python):

x = 4       # x is of type int
x = "Sally" # x is now of type str

x = str(3)    # x will be '3'
y = int(3)    # y will be 3
z = float(3)  # z will be 3.0
