docs(10_Wiki): 위키 전체 재구성 — Topic_* 폴더를 4개 카테고리로 통합 + 대규모 중복 제거

Topic_Agent/Topic_Blog/Topics/Topics_Biz/Topics_Meeting/Topics_Rag의 마크다운 지식 문서를
Topic_General/Topic_Programming/Topic_Graphic/Topic_Business 4개 카테고리로 재분류.

- 중복 제거: frontmatter의 status:duplicate/merged + duplicate_of/redirect_to 필드로
  자기 자신을 중복으로 선언한 리다이렉트 stub 1032개 제거, 완전 동일 내용 파일 472개 제거,
  동일 파일명·다른 내용 충돌 시 더 큰(완전한) 버전만 유지(162개 제거) — 총 1639개 중복 제거.
- 분류: 폴더 단위로 명확한 항목(AI_and_ML/Coding/Architecture 등 → Programming,
  Comfyui/Visual_Effects → Graphic, Topics_Biz/Topics_Meeting/사업 등 → Business,
  Poetic_Blog_Writing/창의성/Game_Design 등 → General)은 폴더 우선순위로,
  나머지 혼재 폴더(Topic_Agent/Topic_Blog/Topics 루트/Thinking & Reasoning/Other/UI_UX_Assets)는
  title/tags 키워드 스코어링으로 파일 단위 분류(불명확한 경우 General로 폴백).
  원본 폴더명은 "From_*" 서브폴더로 보존해 추적 가능성 유지.
- 최종 배치: Programming 2784 / General 1608 / Graphic 285 / Business 249 = 4926개 문서.
- 에이전트 운영 상태(.astra/.agent/.obsidian/sessions/memory/_company/docs/lessons/_shared/src)는
  지식 콘텐츠가 아니므로 재분류 대상에서 제외하고 원위치 유지.
- Topics/Topic_email(상위 보호 폴더 Topic_email과 파일명 100% 중복) 삭제 — 보호 폴더 자체는 미변경.
- 완전히 비게 된 Topic_Agent/Topic_Blog/Topics_Biz/Topics_Rag 폴더 제거.

# Expo 2025 Osaka
## 매 한 줄
> **"매 'Designing Future Society for Our Lives' 매 Yumeshima island, Osaka"**. 매 2025-04-13 ~ 10-13. 매 BIE 등록 — 매 World Expo. 매 highlight: 매 Grand Ring (largest wooden structure), 매 flying car demo, 매 immersive pavilion, 매 AI / robotics. 매 attendance ~28M.
## 매 핵심
### 매 basics
- **Theme**: Designing Future Society for Our Lives.
- **Sub-themes**: Saving Lives, Empowering Lives, Connecting Lives.
- **Location**: Yumeshima, Osaka.
- **Period**: 2025-04-13 to 2025-10-13.
- **Participants**: 158 countries + 7 international orgs.
### 매 architecture
- **Grand Ring** (Sou Fujimoto): 매 largest wooden structure ever (2km 둘레).
- **Pavilion**: 매 each country / sponsor.
- **Signature pavilions** (8): 매 Japanese expert curated.
### 매 tech showcase
- **Flying cars** (eVTOL demo).
- **Avatar robots**.
- **AI translation** (real-time multi-lingual).
- **Sustainable construction** (timber).
- **AR / VR experiences**.
- **IoT cashless**.
### 매 응용 (lessons for tech)
1. **Immersive media** design.
2. **AR / VR** at scale.
3. **Multilingual UX**.
4. **Sustainable infra**.
5. **Crowd flow** (computer vision).
6. **Cashless / digital ID**.
## 💻 패턴 (응용 lessons)
### Multilingual real-time translation
```python
def realtime_translate(audio_stream, target_lang):
"""매 Expo-style booth interaction."""
transcript = whisper.transcribe(audio_stream)
translated = translate(transcript, target_lang)
tts = synthesize(translated, target_lang)
return tts
```
### Crowd flow ML
```python
def predict_pavilion_wait(historical, weather, time_of_day):
"""매 wait time prediction."""
features = encode([historical, weather, time_of_day])
return wait_time_model.predict(features)
```
### Cashless venue (digital ID)
```typescript
class ExpoPay {
async pay(amount: number, vendor: string) {
const token = await getDigitalIDToken();
return fetch('/pay', { method: 'POST', headers: { Authorization: `Bearer ${token}` }, body: JSON.stringify({ amount, vendor }) });
}
}
```
### AR pavilion experience
```javascript
import { ARSession } from '@react-three/xr';
function PavilionAR() {
return (
<ARSession>
<ambientLight intensity={0.5} />
<Scene model="pavilion-content.glb" />
<Hotspot position={[0, 1, -2]} info="Future city design" />
</ARSession>
);
}
```
### Sustainable timber engineering (Grand Ring)
```python
# 매 wood vs concrete CO2
def co2_footprint(material, mass_kg):
factors = {'concrete': 0.1, 'steel': 1.85, 'cross_laminated_timber': -1.0} # 매 CLT 의 carbon sink
return mass_kg * factors[material]
```
### Visitor flow heatmap
```python
def crowd_density(camera_feed):
"""매 head detection + heatmap."""
heads = detect_heads(camera_feed)
H, W = camera_feed.shape[:2]
density = np.zeros((H, W))
for h in heads:
density[h.y, h.x] += 1
return gaussian_filter(density, sigma=10)
```
### Real-time queue management
```python
def dynamic_queue(pavilion, current_wait):
if current_wait > 90:
suggest_alternatives(pavilion.theme)
offer_virtual_queue()
elif current_wait > 60:
recommend_off_peak()
return current_wait
```
### Avatar telepresence
```python
class TelepresenceAvatar:
"""매 remote operator → 매 robot guide."""
def __init__(self, robot):
self.robot = robot
def operate(self, operator_video, operator_audio):
self.robot.face_display.show(operator_video)
self.robot.speakers.play(operator_audio)
self.robot.move(operator_command)
```
## 매 결정 기준 (응용)
| 상황 | Approach |
|---|---|
| Tourist tech showcase | Immersive AR/VR |
| Multilingual venue | Real-time translation |
| Large crowd | CV flow + dynamic queue |
| Sustainable build | Timber structural |
| Payments | Digital ID + cashless |
**기본값**: 매 Expo lessons → 매 immersive + multilingual + crowd-aware + sustainable.
## 🔗 Graph
## 🤖 LLM 활용
**언제**: 매 large-event tech reference. 매 immersive design.
**언제 X**: 매 deep tech detail (specific paper).
## ❌ 안티패턴
- **Tech for tech**: 매 visitor benefit X.
- **Offline-only**: 매 multilingual demand miss.
- **Static queue**: 매 frustration.
## 🧪 검증 / 중복
- Verified (Expo 2025 official, BIE, design news).
- 신뢰도 B.
