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) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

# Nuclear Deterrence Models
|
||||
|
||||
## 매 한 줄
|
||||
> **"매 first strike 의 cost 의 retaliatory 의 unbearable 의 make → 매 attack 의 prevent"**. Nuclear deterrence 매 game-theoretic equilibrium 의 family — Mutually Assured Destruction (MAD), credible-threat signaling, escalation ladders. 매 Cold War-era foundation 의 modern simulations (Plan A by Princeton, ICONS) + 4X game design (Civilization, Hearts of Iron) 의 informs.
|
||||
|
||||
## 매 핵심
|
||||
|
||||
### 매 Foundational Models
|
||||
- **MAD (Mutually Assured Destruction)**: 매 second-strike survivability 매 first strike 의 deters.
|
||||
- **Massive Retaliation (Dulles, 1954)**: 매 any aggression 매 maximum response.
|
||||
- **Flexible Response (Kennedy)**: 매 graduated escalation — match 의 force level.
|
||||
- **Counterforce vs Countervalue**: 매 military targets 의 vs population/cities.
|
||||
|
||||
### 매 Game-Theoretic Lens
|
||||
- **Chicken / Hawk-Dove**: 매 brinkmanship — 매 first 의 swerve 의 lose.
|
||||
- **Schelling 의 Focal Points**: 매 tacit coordination 매 escalation 의 around.
|
||||
- **Credible commitment**: 매 burn-the-boats — 매 retreat option 의 remove.
|
||||
- **Signaling cost**: 매 expensive signals (mobilization) 매 cheap talk 의 outweigh.
|
||||
|
||||
### 매 응용
|
||||
1. 4X game design — diplomacy systems (Civilization VI/VII nuclear units).
|
||||
2. Wargame simulation — Plan A, Sigma war games (Pentagon, RAND).
|
||||
3. Geopolitical training — Foreign Service simulations.
|
||||
|
||||
## 💻 패턴
|
||||
|
||||
### MAD payoff matrix
|
||||
```typescript
|
||||
// Row = US strategy, Col = USSR strategy. Values: [US payoff, USSR payoff]
|
||||
const madMatrix = {
|
||||
cooperate_cooperate: [3, 3],
|
||||
cooperate_strike: [-100, 1],
|
||||
strike_cooperate: [1, -100],
|
||||
strike_strike: [-100, -100],
|
||||
} as const;
|
||||
|
||||
function nashCheck(strategy: keyof typeof madMatrix): boolean {
|
||||
// 매 strike_strike 의 not 매 deviating cooperate 의 worse
|
||||
return false; // mutual cooperation 매 not Nash 의 single-shot, repeated game 매 stable
|
||||
}
|
||||
```
|
||||
|
||||
### Second-strike survivability
|
||||
```typescript
|
||||
interface Arsenal {
|
||||
silos: number;
|
||||
submarines: number;
|
||||
bombers: number;
|
||||
silos_survival: number; // ~0.05
|
||||
sub_survival: number; // ~0.95
|
||||
bomber_survival: number; // ~0.30
|
||||
}
|
||||
|
||||
function expectedRetaliation(a: Arsenal, warheadsPerPlatform: number): number {
|
||||
return (
|
||||
a.silos * a.silos_survival +
|
||||
a.submarines * a.sub_survival +
|
||||
a.bombers * a.bomber_survival
|
||||
) * warheadsPerPlatform;
|
||||
}
|
||||
|
||||
function isMADStable(us: Arsenal, ussr: Arsenal, warheads: number, threshold = 200): boolean {
|
||||
return (
|
||||
expectedRetaliation(us, warheads) > threshold &&
|
||||
expectedRetaliation(ussr, warheads) > threshold
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
### Escalation ladder (Kahn)
|
||||
```typescript
|
||||
const ESCALATION_LADDER = [
|
||||
{ rung: 1, name: 'Crisis declaration', kineticForce: false },
|
||||
{ rung: 5, name: 'Show of force', kineticForce: false },
|
||||
{ rung: 10, name: 'Conventional war', kineticForce: true },
|
||||
{ rung: 15, name: 'Tactical nuclear', kineticForce: true },
|
||||
{ rung: 20, name: 'Strategic limited strike', kineticForce: true },
|
||||
{ rung: 44, name: 'Spasm war (full exchange)', kineticForce: true },
|
||||
];
|
||||
|
||||
function escalate(current: number, signal: 'firm' | 'reciprocate' | 'deescalate'): number {
|
||||
if (signal === 'firm') return Math.min(44, current + 2);
|
||||
if (signal === 'reciprocate') return current;
|
||||
return Math.max(1, current - 3);
|
||||
}
|
||||
```
|
||||
|
||||
### Brinkmanship simulation (Chicken)
|
||||
```typescript
|
||||
interface Player { resolve: number; rationality: number; }
|
||||
|
||||
function chickenOutcome(a: Player, b: Player): 'a_yields' | 'b_yields' | 'crash' {
|
||||
// 매 brinkmanship — both swerve 의 mutual benefit, 매 neither swerve 의 catastrophe
|
||||
const aYieldP = 1 - a.resolve;
|
||||
const bYieldP = 1 - b.resolve;
|
||||
const r = Math.random();
|
||||
if (r < aYieldP * (1 - bYieldP)) return 'a_yields';
|
||||
if (r < aYieldP * (1 - bYieldP) + bYieldP * (1 - aYieldP)) return 'b_yields';
|
||||
if (r < aYieldP * (1 - bYieldP) + bYieldP * (1 - aYieldP) + aYieldP * bYieldP) return 'a_yields';
|
||||
return 'crash';
|
||||
}
|
||||
```
|
||||
|
||||
### Credible threat (Schelling commitment device)
|
||||
```typescript
|
||||
class Commitment {
|
||||
// 매 retreat 의 cost 의 raise 하여 매 threat 의 credible 의 make
|
||||
constructor(
|
||||
public publicAnnouncement: boolean,
|
||||
public alliancesAtStake: number,
|
||||
public sunkInvestment: number,
|
||||
) {}
|
||||
|
||||
credibility(): number {
|
||||
return (
|
||||
(this.publicAnnouncement ? 0.4 : 0) +
|
||||
Math.min(0.4, this.alliancesAtStake * 0.1) +
|
||||
Math.min(0.2, this.sunkInvestment / 1e9 * 0.05)
|
||||
);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 매 결정 기준
|
||||
| 상황 | Approach |
|
||||
|---|---|
|
||||
| Symmetric superpowers | MAD + arms control treaties |
|
||||
| Asymmetric (one weak) | Flexible response + extended deterrence |
|
||||
| Multiparty (3+ nuclear states) | Stability erosion — 매 stochastic escalation risk |
|
||||
| Game design (4X / wargame) | Schelling-flavored mechanics — credible-threat units, escalation tracker |
|
||||
|
||||
**기본값**: MAD model 의 baseline + flexible response 의 layered nuance.
|
||||

||||

- Adjacent: [[Algorithmic Rhetoric]] · [[Alliance (동맹)]] · [[4X 시스템 (4X System)]]
|
||||
|
||||
## 🤖 LLM 활용
|
||||
**언제**: Wargame scenario drafting, doctrine summary, simulation NPC rhetoric generation.
|
||||
**언제 X**: Real-world policy advice, classified-domain reasoning, live crisis decision support.
|
||||
|
||||
## ❌ 안티패턴
|
||||
- **Single-strategy doctrine**: 매 only-massive-retaliation 매 small-conflict 매 incredible.
|
||||
- **Ignoring second-strike**: 매 silo-only arsenal 매 vulnerable, MAD 의 collapse.
|
||||
- **Cheap-talk threats**: 매 cost-free threats 매 not credible — game-theoretic noise.
|
||||
- **Ladder collapse**: 매 step-skipping 매 stability 의 destroy.
|
||||
|
||||
## 🧪 검증 / 중복
|
||||
- Verified (Schelling "Strategy of Conflict", Kahn "On Escalation", Princeton SGS Plan A 2019, RAND deterrence literature 2020-2024).
|
||||
- 신뢰도 A.
