# 🆕 Introducing Cortex - Configuration & Coordination Command Center

**Never manage .env files again!** Cortex brings encrypted configuration management and distributed coordination to Brainy:

```bash
# Store all your configs encrypted in Brainy
npx cortex init
cortex config set DATABASE_URL postgres://localhost/mydb
cortex config set STRIPE_KEY sk_live_... --encrypt

# In your app - just one line!
await brainy.loadEnvironment()  # All configs loaded & decrypted!
```

# The Search Problem Every Developer Faces

**"I need to find similar content, explore relationships, AND filter by metadata - but that means juggling 3+ databases"**

❌ **Current Reality**: Pinecone + Neo4j + Elasticsearch + Custom Sync Logic  
✅ **Brainy Reality**: One database. One API. All three search types.

## 🔥 The Power of Three-in-One Search

```javascript
// This ONE query does what used to require 3 databases:
const results = await brainy.search("AI startups in healthcare", 10, {
  // 🔍 Vector: Semantic similarity 
  includeVerbs: true,
  
  // 🔗 Graph: Relationship traversal
  verbTypes: ["invests_in", "partners_with"],
  
  // 📊 Faceted: MongoDB-style filtering  
  metadata: {
    industry: "healthcare",
    funding: { $gte: 1000000 },
    stage: { $in: ["Series A", "Series B"] }
  }
})
// Returns: Companies similar to your query + their relationships + matching your criteria
```

**Three search paradigms. One lightning-fast query. Zero complexity.**

## 🚀 Install & Go

```bash
npm install @soulcraft/brainy
```

```javascript
import { BrainyData } from '@soulcraft/brainy'

const brainy = new BrainyData()  // Auto-detects your environment
await brainy.init()              // Auto-configures everything

// Add data with relationships
const openai = await brainy.add("OpenAI", { type: "company", funding: 11000000 })
const gpt4 = await brainy.add("GPT-4", { type: "product", users: 100000000 })
await brainy.relate(openai, gpt4, "develops")

// Search across all dimensions
const results = await brainy.search("AI language models", 5, {
  metadata: { funding: { $gte: 10000000 } },
  includeVerbs: true
})
```

**That's it. You just built a knowledge graph with semantic search and faceted filtering in 8 lines.**

## ⚙️ Configuration Options

Brainy works great with **zero configuration**, but you can customize it for your specific needs:

### 🚀 Quick Start (Recommended)
```javascript
const brainy = new BrainyData()  // Auto-detects everything
await brainy.init()              // Zero config needed
```

### 🎯 Specialized Configurations

#### Writer Service with Deduplication
Perfect for high-throughput data ingestion with smart caching:
```javascript
const brainy = new BrainyData({
  writeOnly: true,        // Skip search index loading
  allowDirectReads: true  // Enable ID-based lookups for deduplication
})
// ✅ Can: add(), get(), has(), exists(), getMetadata(), getBatch()
// ❌ Cannot: search(), similar(), query() (saves memory & startup time)
```

#### Pure Writer Service
For maximum performance data ingestion only:
```javascript
const brainy = new BrainyData({
  writeOnly: true,         // No search capabilities
  allowDirectReads: false  // No read operations at all
})
// ✅ Can: add(), addBatch(), relate()
// ❌ Cannot: Any read operations (fastest startup)
```

#### Read-Only Service
For search-only applications with immutable data:
```javascript
const brainy = new BrainyData({
  readOnly: true,    // Block all write operations
  frozen: true       // Block statistics updates and optimizations
})
// ✅ Can: All search operations
// ❌ Cannot: add(), update(), delete()
```

#### Custom Storage & Performance
```javascript
const brainy = new BrainyData({
  // Storage options
  storage: {
    type: 's3',                    // 's3', 'memory', 'filesystem'
    requestPersistentStorage: true, // Browser: request persistent storage
    s3Storage: {
      bucketName: 'my-vectors',
      region: 'us-east-1'
    }
  },
  
  // Performance tuning
  hnsw: {
    maxConnections: 16,      // Higher = better search quality
    efConstruction: 200,     // Higher = better index quality
    useOptimized: true       // Enable disk-based storage
  },
  
  // Embedding customization
  embeddingFunction: myCustomEmbedder,
  distanceFunction: 'euclidean'  // 'cosine', 'euclidean', 'manhattan'
})
```

#### Distributed Services
```javascript
// Microservice A (Writer)
const writerService = new BrainyData({
  writeOnly: true,
  allowDirectReads: true,  // For deduplication
  defaultService: 'data-ingestion'
})

// Microservice B (Reader) 
const readerService = new BrainyData({
  readOnly: true,
  defaultService: 'search-api'
})

// Full-featured service
const hybridService = new BrainyData({
  writeOnly: false,  // Can read and write
  defaultService: 'full-stack-app'
})
```

### 🟢 Node.js / Serverless / Edge

```javascript
import { BrainyData } from '@soulcraft/brainy'

// SAME CODE works in Node.js, Vercel, Netlify, Cloudflare Workers, Deno, Bun
const brainy = new BrainyData()
await brainy.init()  // Auto-detects environment and optimizes

// Add entities and relationships
await brainy.add("Python is great for data science", { type: "fact" })
await brainy.add("JavaScript rules the web", { type: "fact" })

// Search by meaning
const results = await brainy.search("programming languages", 5)

// Optional: Production with S3/R2 storage (auto-detected in cloud environments)
const productionBrainy = new BrainyData({
  storage: {
    s3Storage: { bucketName: process.env.BUCKET_NAME }
  }
})
```

**That's it! Same code, everywhere. Zero-to-Smart™**

Brainy automatically detects and optimizes for your environment:

| Environment | Storage | Optimization |
|-------------|---------|-------------|
| 🌐 Browser | OPFS | Web Workers, Memory Cache |
| 🟢 Node.js | FileSystem / S3 | Worker Threads, Clustering |
| ⚡ Serverless | S3 / Memory | Cold Start Optimization |
| 🔥 Edge | Memory / KV | Minimal Footprint |

## 🌐 Distributed Mode (NEW!)

**Scale horizontally with zero configuration!** Brainy now supports distributed deployments with automatic coordination:

- **🌐 Multi-Instance Coordination** - Multiple readers and writers working in harmony
- **🏷️ Smart Domain Detection** - Automatically categorizes data (medical, legal, product, etc.)
- **📊 Real-Time Health Monitoring** - Track performance across all instances
- **🔄 Automatic Role Optimization** - Readers optimize for cache, writers for throughput
- **🗂️ Intelligent Partitioning** - Hash-based partitioning for perfect load distribution

```javascript
// Writer Instance - Ingests data from multiple sources
const writer = new BrainyData({
  storage: { s3Storage: { bucketName: 'my-bucket' } },
  distributed: { role: 'writer' }  // Explicit role for safety
})

// Reader Instance - Optimized for search queries
const reader = new BrainyData({
  storage: { s3Storage: { bucketName: 'my-bucket' } },
  distributed: { role: 'reader' }  // 80% memory for cache
})

// Data automatically gets domain tags
await writer.add("Patient shows symptoms of...", {
  diagnosis: "flu"  // Auto-tagged as 'medical' domain
})

// Domain-aware search across all partitions
const results = await reader.search("medical symptoms", 10, {
  filter: { domain: 'medical' }  // Only search medical data
})

// Monitor health across all instances
const health = reader.getHealthStatus()
console.log(`Instance ${health.instanceId}: ${health.status}`)
```

### 🐳 NEW: Zero-Config Docker Deployment

**Deploy to any cloud with embedded models - no runtime downloads needed!**

```dockerfile
# One line extracts models automatically during build
RUN npm run download-models

# Deploy anywhere: Google Cloud, AWS, Azure, Cloudflare, etc.
```

- **⚡ 7x Faster Cold Starts** - Models embedded in container, no downloads
- **🌐 Universal Cloud Support** - Same Dockerfile works everywhere  
- **🔒 Offline Ready** - No external dependencies at runtime
- **📦 Zero Configuration** - Automatic model detection and loading

```javascript
// Zero configuration - everything optimized automatically!
const brainy = new BrainyData()  // Auto-detects environment & optimizes
await brainy.init()

// Caching happens automatically - no setup needed!
const results1 = await brainy.search('query', 10)  // ~50ms first time
const results2 = await brainy.search('query', 10)  // <1ms cached hit!

// Advanced pagination works instantly
const page1 = await brainy.searchWithCursor('query', 100)
const page2 = await brainy.searchWithCursor('query', 100, {
  cursor: page1.cursor  // Constant time, no matter how deep!
})

// Monitor auto-optimized performance
const stats = brainy.getCacheStats()
console.log(`Auto-tuned cache hit rate: ${(stats.search.hitRate * 100).toFixed(1)}%`)
```
