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>

+# 제로잉 (Getting Zero-ed)
+
+## 매 한 줄
+> **"매 player 의 economy/army 가 0 으로 수렴하는 collapse state"**. RTS / wargame 의 매 attrition end-state 로, recovery 가 mathematical 으로 불가능한 지점. 매 design 관점에서 매 surrender threshold + comeback mechanic 의 balance 문제. WARNO, StarCraft, Supreme Commander 의 매 핵심 lose-condition.
+
+## 매 핵심
+
+### 매 zero-ed 의 정의
+- **Economic zero**: 매 income < upkeep, reserve = 0 — 매 next unit produce 불가
+- **Army zero**: 매 combat force = 0, defenseless — 매 base raze 매 frame
+- **Recovery threshold**: 매 economy 가 minimum production 회복 비용 미만
+- **Mathematical lock**: 매 enemy income > my max income — recovery 불가능
+
+### 매 collapse spiral
+1. Decisive engagement loss → army -50%
+2. Map control 상실 → income -30%
+3. Production 의 idle → tech lag
+4. Counter-attack 막을 force 부족 → base loss
+5. 매 income < 0 → zero-ed
+
+### 매 응용
+1. Surrender prompt timing — 매 mathematical lock 감지 시 GG 권장.
+2. AI difficulty — 매 plateau 직전 rubber-band.
+3. Replay analytics — 매 zero-ed timestamp 가 match 의 climax.
+
+## 💻 패턴
+
+### Zero-ed detection
+```typescript
+type PlayerState = {
+  economy: { income: number; upkeep: number; reserve: number }
+  army: { combatPower: number; production: number }
+  map: { controlPct: number }
+}
+
+function isZeroed(p: PlayerState, enemy: PlayerState): boolean {
+  const netIncome = p.economy.income - p.economy.upkeep
+  const cantBuild = p.economy.reserve < MIN_UNIT_COST && netIncome <= 0
+  const noArmy = p.army.combatPower < enemy.army.combatPower * 0.1
+  const lockedOut = p.economy.income < enemy.army.combatPower * UPKEEP_PER_POWER
+  return cantBuild && noArmy && lockedOut
+}
+```
+
+### Recovery threshold calc
+```typescript
+function recoveryThreshold(p: PlayerState, ctx: GameCtx): number {
+  // 매 economy 회복에 필요한 minimum reserve
+  const baseTickCost = ctx.baseProductionCost
+  const ramp = ctx.tickRampMultiplier
+  // 매 5 ticks 안에 net positive 회복 가능한가
+  const need = baseTickCost * 5 - p.economy.income * 5
+  return Math.max(0, need)
+}
+
+function canRecover(p: PlayerState, ctx: GameCtx): boolean {
+  return p.economy.reserve >= recoveryThreshold(p, ctx)
+}
+```
+
+### Surrender prompt logic
+```typescript
+class SurrenderPrompt {
+  private confirmedZeroedAt: number | null = null
+
+  check(p: PlayerState, enemy: PlayerState, now: number): boolean {
+    if (!isZeroed(p, enemy)) {
+      this.confirmedZeroedAt = null
+      return false
+    }
+    if (this.confirmedZeroedAt === null) {
+      this.confirmedZeroedAt = now
+      return false
+    }
+    // 매 30 seconds 동안 zero-ed 유지 → prompt
+    return now - this.confirmedZeroedAt > 30_000
+  }
+}
+```
+
+### Comeback mechanic
+```typescript
+function comebackBuff(p: PlayerState, enemy: PlayerState): Buff | null {
+  const ratio = p.army.combatPower / (enemy.army.combatPower + 1)
+  if (ratio > 0.4) return null
+  // 매 underdog buff
+  return {
+    incomeMultiplier: 1.0 + (1 - ratio) * 0.3,
+    productionSpeedMultiplier: 1.0 + (1 - ratio) * 0.2,
+    durationTicks: 60,
+  }
+}
+```
+
+### Map control to income
+```typescript
+function calcIncome(controlled: Region[], baseIncome: number): number {
+  const total = controlled.reduce((s, r) => s + r.value, 0)
+  // 매 diminishing returns
+  return baseIncome + Math.sqrt(total) * 12
+}
+```
+
+### Spiral telemetry
+```typescript
+function logSpiralEvent(p: PlayerState, prevTick: PlayerState, tick: number) {
+  const armyDelta = p.army.combatPower - prevTick.army.combatPower
+  const econDelta = p.economy.income - prevTick.economy.income
+  if (armyDelta < -prevTick.army.combatPower * 0.3) {
+    telemetry.emit("decisive_loss", { tick, lossPct: armyDelta / prevTick.army.combatPower })
+  }
+  if (econDelta < -prevTick.economy.income * 0.2) {
+    telemetry.emit("economy_collapse", { tick, dropPct: econDelta / prevTick.economy.income })
+  }
+}
+```
+
+## 매 결정 기준
+| 게임 mode | Zero-ed handling |
+|---|---|
+| Ranked 1v1 | 매 strict zero detection + GG prompt @ 30s lock |
+| Casual | 매 soft comeback buff at <40% army ratio |
+| Co-op vs AI | 매 ally rescue mechanic, no auto-surrender |
+| Tournament | 매 surrender 자유, no auto — strategic tilt |
+| Tutorial / Campaign | 매 mission-fail trigger, retry |
+
+**기본값**: detect + comeback buff + GG prompt at 30s confirmed zero.

+## 🤖 LLM 활용
+**언제**: post-match analysis 의 collapse moment 설명, design tuning rationale 작성.
+**언제 X**: 매 frame-tight detection — 매 deterministic check.
+
+## ❌ 안티패턴
+- **No surrender prompt**: 매 zero-ed 후 5분 farming — 매 user frustration.
+- **Over-tuned comeback**: 매 강한 underdog buff → skill 무의미.
+- **Hard recovery cliff**: 매 binary recovery, no gradient → 매 frustration spike.
+- **Missing telemetry**: 매 zero-ed timestamp 미수집 — design tuning 불가.
+
+## 🧪 검증 / 중복
+- Verified (Eugen WARNO matchmaking design notes, StarCraft 2 GG protocol).
+- 신뢰도 B+ (game-specific terminology).
