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 Tuples

🎯 한 줄 통찰 (One-line insight)

A tuple is an ordered, immutable, duplicate-allowing collection written with round brackets — and a single-item tuple requires a trailing comma, or Python won't recognize it as a tuple at all. [S1]

🧠 핵심 개념 (Core concepts)

  • Tuple — one of Python's 4 built-in collection types; ordered and unchangeable, written with (). [S1]
  • Ordered — item order is fixed and persists. [S1]
  • Unchangeable (immutable) — cannot change, add, or remove items after creation. [S1]
  • Allows duplicates — indexed, so identical values can repeat. [S1]
  • Single-item tuple gotcha("apple",) is a tuple; ("apple") (no comma) is just a string in parentheses. [S1]
  • tuple() constructor — alternative creation syntax. [S1]

🧩 추출된 패턴 (Extracted patterns)

  • Trailing-comma requirement — the single most common tuple mistake is omitting the comma for a one-item tuple, silently producing a non-tuple instead of raising an error. [S1]

📖 세부 내용 (Details)

  • Basic creation: thistuple = ("apple", "banana", "cherry"). [S1]
  • Duplicates allowed: thistuple = ("apple", "banana", "cherry", "apple", "cherry"). [S1]
  • Single-item tuple: thistuple = ("apple",) # tuple vs thistuple = ("apple") # NOT a tuple. [S1]
  • Constructor: thistuple = tuple(("apple", "banana", "cherry")). [S1]

⚖️ 모순 및 업데이트 (Contradictions & updates)

소스에서 모순되는 정보는 발견되지 않음.

🛠️ 적용 사례 (Applied in summary)

현재 발견된 실제 적용 사례가 없습니다 — List와 대비되는 불변 컬렉션으로서 이후 Access/Update/Unpack/Loop/Join/Methods 챕터의 기초가 된다. [S1]

💻 코드 패턴 (Code patterns)

Single-item tuple gotcha (Python):

thistuple = ("apple",)   # a tuple
print(type(thistuple))   # <class 'tuple'>

thistuple = ("apple")    # NOT a tuple
print(type(thistuple))   # <class 'str'>
