# Structural Dynamics and Tactical Evolution of the Combat Ecosystem

## 매 한 줄
> **"매 tactical layer 의 time-axis evolution 의 분석"**. 매 [[Structural-Dynamics-of-Combat-Ecosystem]] 의 4-layer model 의 temporal extension — 매 patch cadence, player-discovery curve, esports refinement, content drop 의 cumulative effect 의 modeling. 매 multi-year title 의 living balance 의 frame.

## 매 핵심

### 매 4 axis (temporal)
1. **Patch axis**: 매 dev-driven adjustment 의 timeline.
2. **Discovery axis**: 매 player community 의 strategy uncover.
3. **Esports axis**: 매 pro scene 의 refinement.
4. **Content axis**: 매 new unit/map 의 drop.

### 매 evolution phase
- **Launch**: 매 dev-intended meta — fragile equilibrium.
- **Discovery**: 매 community 의 tech 의 surface — 1st meta shift.
- **Refinement**: 매 pro 의 micro 의 polish — 매 meta convergence.
- **Stagnation**: 매 dominant strategy 의 lock-in — 매 churn risk.
- **Refresh**: 매 patch/content 의 inject — 매 cycle restart.

### 매 응용
1. Patch cadence design — 매 stagnation 의 prevention.
2. Esports league season planning.
3. Telemetry-driven predict-vs-actual meta delta.

## 💻 패턴

### Meta state tracker
```typescript
type MetaPhase = 'launch' | 'discovery' | 'refinement' | 'stagnation' | 'refresh';

interface MetaSnapshot { date: string; topUnits: string[]; diversity: number; phase: MetaPhase; }

export function classifyPhase(snapshot: MetaSnapshot, prev: MetaSnapshot[]): MetaPhase {
  if (prev.length < 2) return 'launch';
  const trend = snapshot.diversity - prev.at(-1)!.diversity;
  if (snapshot.diversity < 0.3 && Math.abs(trend) < 0.02) return 'stagnation';
  if (trend > 0.1) return 'refresh';
  if (snapshot.diversity > 0.6) return 'discovery';
  return 'refinement';
}
```

### Diversity index (Shannon)
```typescript
export function diversityIndex(pickCounts: Record<string, number>): number {
  const total = Object.values(pickCounts).reduce((a, b) => a + b, 0);
  if (total === 0) return 0;
  return -Object.values(pickCounts).reduce((s, c) => {
    const p = c / total;
    return p > 0 ? s + p * Math.log2(p) : s;
  }, 0);
}
```

### Discovery rate model
```typescript
// 매 logistic curve 의 strategy discovery
export function discoveryProgress(daysSinceLaunch: number, complexity: number): number {
  const k = 0.05 / complexity; // higher complexity → slower
  return 1 / (1 + Math.exp(-k * (daysSinceLaunch - 30 * complexity)));
}
```

### Patch impact decay
```typescript
export function patchDecay(daysSincePatch: number, halfLifeDays = 14): number {
  return Math.pow(0.5, daysSincePatch / halfLifeDays);
}
```

### Esports vs ladder delta
```typescript
interface PickStats { ladder: Record<string, number>; pro: Record<string, number>; }

export function esportsDelta(p: PickStats): { unit: string; delta: number }[] {
  const all = new Set([...Object.keys(p.ladder), ...Object.keys(p.pro)]);
  return [...all].map(u => ({
    unit: u,
    delta: (p.pro[u] ?? 0) - (p.ladder[u] ?? 0),
  })).sort((a, b) => Math.abs(b.delta) - Math.abs(a.delta));
}
```

### Content drop scheduler
```typescript
interface ContentPlan { name: string; date: string; type: 'unit' | 'map' | 'mode'; expectedDiversityDelta: number; }

export function planNextDrop(currentDiversity: number, history: ContentPlan[]): ContentPlan | null {
  if (currentDiversity > 0.5) return null; // healthy
  const last = history.at(-1);
  if (last && Date.now() - new Date(last.date).getTime() < 30 * 86400_000) return null;
  return { name: 'TBD', date: new Date().toISOString(), type: 'unit', expectedDiversityDelta: 0.15 };
}
```

## 매 결정 기준
| 상황 | Approach |
|---|---|
| 매 launch phase | Light-touch patches — let discovery breathe. |
| 매 stagnation 의 detected | Major content drop or rework patch. |
| 매 esports vs ladder split | Mode-specific balance (esp. fast/slow). |
| 매 mature title (5+ yr) | Focus on QOL + cosmetic content over balance churn. |

**기본값**: monthly diversity check + quarterly content drop + biweekly micro-patch.

## 🤖 LLM 활용
**언제**: meta narrative 의 summary, content roadmap 의 brainstorm, patch announcement 의 draft.
**언제 X**: 매 telemetry pipeline (Shannon entropy 의 deterministic).

## ❌ 안티패턴
- **Patch fatigue**: 매 weekly major change — pro/community whiplash.
- **No diversity metric**: 매 stagnation 의 invisible.
- **Ignoring esports delta**: 매 ladder-vs-pro 의 split-meta blind.
- **Content as balance crutch**: 매 power creep 의 inevitable.

## 🧪 검증 / 중복
- Verified: SC2 LotV balance history, Smash Ultimate community tier list evolution, DOTA 2 7.x patches.
- 신뢰도 A.
