# NodeBuster – Polyglot Network Topology Cache Busting System

**Engineering Team:** OBINexus Protocol Engineering Group  
**Project:** Aegis Technical Specification Implementation  
**Repository:** [@obinexus/node-buster](https://github.com/obinexus/node-buster)  
**Installation:** `npm install @obinexus/node-buster`  
**CLI Usage:** `npx buster [command] [options]`

---

## 🏗️ Single-Pass Architecture & Sinphasé Principles

NodeBuster implements mathematically rigorous, single-pass architecture for zero-overhead dependency busting in distributed Node.js environments. Following Sinphasé (Single-Pass Hierarchical Structuring) methodology, the system maintains O(1) operational overhead guarantees while providing cryptographic security across network topologies.

### Consumer/Exporter Pattern Architecture

```typescript
// Consumer Pattern - Import cache strategies
import { CacheStrategyManager, TopologyCoordinator } from '@obinexus/node-buster';

// Exporter Pattern - Compose and export optimized configurations
export const bustConfig = new CacheStrategyManager({
  strategy: 'arc',     // Adaptive Replacement Cache
  topology: 'mesh',    // Network topology for distributed busting
  overhead: 'O(1)'     // Guaranteed performance constraint
});
```

## 📦 Installation & Quick Start

### NPM Installation
```bash
npm install @obinexus/node-buster
# Global CLI access
npm install -g @obinexus/node-buster
```

### Immediate Usage
```bash
# Bust specific dependency with LRU strategy
npx buster --dep react --strategy lru --topology star

# Bust large dependencies with mesh topology
npx buster --dep "@types/node" --strategy arc --topology mesh --ttl 30000

# CDN-style distributed busting
npx buster --network-wide --strategy belady --cdn-mode
```

## 🧠 Cache Strategy Composition Framework

NodeBuster implements UML-style cache strategy composition through technique-based inheritance patterns:

### Core Cache Strategies (`src/core/cache-strategy-manager/`)

#### **LRU (Least Recently Used)** - O(1) Access Order Tracking
```typescript
interface LRUStrategy extends CacheStrategy {
  technique: 'lru';
  evictionPolicy: 'access-order';
  complexity: 'O(1)';
  useCase: 'General-purpose dependency caching';
}
```

#### **MRU (Most Recently Used)** - Streaming Optimization
```typescript
interface MRUStrategy extends CacheStrategy {
  technique: 'mru';
  evictionPolicy: 'reverse-access-order';
  complexity: 'O(1)';
  useCase: 'Streaming applications, build pipelines';
}
```

#### **ARC (Adaptive Replacement Cache)** - Dynamic Strategy Selection
```typescript
interface ARCStrategy extends CacheStrategy {
  technique: 'arc';
  evictionPolicy: 'adaptive-lru-lfu';
  complexity: 'O(1) amortized';
  useCase: 'Unknown access patterns, production systems';
}
```

#### **Belady's Optimal** - Theoretical Optimal Approximation  
```typescript
interface BeladyStrategy extends CacheStrategy {
  technique: 'belady';
  evictionPolicy: 'future-access-prediction';
  complexity: 'O(1) heuristic';
  useCase: 'Performance benchmarking, theoretical analysis';
}
```

### Strategy Composition Schema

```typescript
class CacheStrategyComposer {
  compose(primary: CacheStrategy, fallback: CacheStrategy): CompositeStrategy {
    return {
      name: `${primary.technique}+${fallback.technique}`,
      execute: (cache) => primary.execute(cache) || fallback.execute(cache),
      complexity: 'O(1)', // Maintained through composition
      governance: 'Sinphasé-compliant'
    };
  }
}
```

## 🌐 Network Topology Support

NodeBuster supports distributed dependency busting across multiple network topologies:

### **Star Topology** - Central Hub Coordination
```bash
npx buster --topology star --hub-node main --dependencies express,lodash,react
```

### **Mesh Topology** - Full Peer-to-Peer Relay
```bash
npx buster --topology mesh --peer-discovery auto --strategy arc
```

### **Ring Topology** - Sequential Bust Handoffs  
```bash
npx buster --topology ring --ring-order "dev,staging,prod" --ttl 60000
```

### **Hybrid Topology** - Mixed Strategy Deployment
```bash
npx buster --topology hybrid --config ./topology.json --cdn-integration
```

## 🔧 Technical Implementation Structure

### Core Module Priority Matrix (`src/core/`)

| **Module** | **Priority** | **Function** | **O(1) Guarantee** |
|------------|--------------|--------------|-------------------|
| `topology-manager` | 1 | Network coordination | ✅ Deterministic routing |
| `memory-buster` | 2 | Runtime invalidation | ✅ In-place replacement |
| `cache-strategy-manager` | 3 | Adaptive caching | ✅ Amortized complexity |
| `crypto-verifier` | 4 | Security validation | ✅ Precomputed proofs |
| `delta-processor` | 5 | State compression | ✅ Bounded delta size |
| `registry-coordinator` | 6 | Lifecycle management | ✅ Constant overhead |

### Build Configuration (`rollup.config.js`)

```javascript
// Sinphasé-compliant build configuration
export default {
  input: 'src/index.ts',
  output: [
    { 
      file: 'dist/buster.cjs.js', 
      format: 'cjs',
      exports: 'named'
    },
    { 
      file: 'dist/buster.esm.js', 
      format: 'esm' 
    },
    { 
      file: 'dist/buster.umd.js', 
      format: 'umd',
      name: 'NodeBuster'
    }
  ],
  external: ['crypto', 'fs', 'path'],
  plugins: [
    typescript({
      declaration: true,
      declarationDir: 'dist/types'
    }),
    resolve(),
    commonjs()
  ]
};
```

## 💻 Programmatic API

### Consumer Pattern Usage

```typescript
import { 
  NodeBuster, 
  CacheStrategyManager,
  TopologyCoordinator 
} from '@obinexus/node-buster';

// Initialize with cost function constraints
const buster = new NodeBuster({
  strategy: 'arc',
  topology: 'mesh',
  costFunction: {
    maxExecutionTime: 10,  // O(1) constraint
    memoryLimit: 1024,     // Bounded resources
    networkTimeout: 5000   // Deterministic behavior
  }
});

// Large dependency busting with zero overhead
await buster.bustDependency('@types/node', {
  cacheStrategy: 'lru',
  networkPropagation: true,
  cdnOptimization: true,
  ttl: 30000
});

// Consumer/Exporter pattern for team coordination
export const teamBustConfig = buster.exportConfiguration();
```

### Exporter Pattern for CDN-Style Distribution

```typescript
// Export optimized configurations for distributed teams
class TeamCacheExporter {
  static exportOptimizedConfig(): BustConfiguration {
    return {
      strategies: ['arc', 'lru', 'belady'],
      topologies: ['mesh', 'star'],
      governance: 'Sinphasé-O(1)-compliant',
      cdnCompatible: true
    };
  }
}
```

## 📊 Performance Guarantees & Validation

### Mathematical Complexity Bounds

```typescript
interface PerformanceGuarantees {
  communication: 'O(n · log m)';    // n=nodes, m=message_size
  computation: 'O(1) amortized';    // Per cache operation
  memory: 'O(k · log n)';           // k=cache_size, n=nodes
  networkOverhead: 'O(log n)';      // Topology-dependent
}
```

### Sinphasé Compliance Validation

```bash
# Automated O(1) constraint verification
npx buster --validate-complexity --performance-profile production

# NASA-STD-8739.8 compliance testing
npx buster --safety-critical-validation --deterministic-execution

# Consumer/Exporter pattern integrity
npx buster --validate-composition --audit-trail
```

---

## 🔒 Security & Cryptographic Verification

### Zero-Knowledge Overhead Protocol

```typescript
interface CryptographicSecurity {
  primitives: ['RSA', 'ECC', 'Lattice-based'];
  verification: 'Zero-knowledge proofs';
  overhead: 'O(1) cryptographic operations';
  compliance: 'NASA-STD-8739.8';
}
```

### Audit Trail Generation

```bash
# Cryptographic audit trail for dependency busting
npx buster --audit-mode --crypto-verify --trail-output ./audit-log.json

# Consumer/Exporter pattern security validation
npx buster --security-validate --pattern-integrity-check
```
