**🧠 Brainy 2.0 - The Universal Knowledge Protocol™**

**World's first Triple Intelligence™ database**—unifying vector similarity, graph relationships, and document filtering in one magical API. Model ANY data from ANY domain using 31 standardized noun types × 40 verb types.

**Why Brainy Leads**: We're the first to solve the impossible—combining three different database paradigms (vector, graph, document) into one unified query interface. This breakthrough enables us to be the Universal Knowledge Protocol where all tools, augmentations, and AI models speak the same language.

**Build once, integrate everywhere.** O(log n) performance, 3ms search latency, 24MB memory footprint.

## 🎉 What's New in 2.0

- **World's First Triple Intelligence™**: Unified vector + graph + document in ONE query
- **Universal Knowledge Protocol**: 31 nouns × 40 verbs standardize all knowledge
- **Infinite Expressiveness**: Model ANY data with unlimited metadata
- **API Consolidation**: 15+ methods → 2 clean APIs (`search()` and `find()`)
- **Natural Language**: Ask questions in plain English
- **Zero Configuration**: Works instantly, no setup required
- **O(log n) Performance**: Binary search on sorted indices
- **Perfect Interoperability**: All tools and AI models speak the same language

## ⚡ Quick Start - Zero Configuration

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

### 🎯 **True Zero Configuration**
```javascript
import { BrainyData } from '@soulcraft/brainy'

// Just this - auto-detects everything!
const brain = new BrainyData()
await brain.init()

// Add entities (nouns) with automatic embedding
const jsId = await brain.addNoun("JavaScript is a programming language", { 
  type: "language", 
  year: 1995,
  paradigm: "multi-paradigm"
})

const nodeId = await brain.addNoun("Node.js runtime environment", {
  type: "runtime",
  year: 2009,
  platform: "server-side"
})

// Create relationships (verbs) between entities
await brain.addVerb(nodeId, jsId, "executes", {
  since: 2009,
  performance: "high"
})

// Natural language search with graph relationships
const results = await brain.find("programming languages used by server runtimes")

// Triple Intelligence: vector + metadata + relationships
const filtered = await brain.find({
  like: "JavaScript",                    // Vector similarity
  where: { type: "language" },           // Metadata filtering  
  connected: { from: nodeId, depth: 1 }  // Graph relationships
})
```

## 📋 System Requirements

**Node.js Version:** 22 LTS or later (recommended)

- ✅ **Node.js 22 LTS** - Fully supported and recommended for production
- ✅ **Node.js 20 LTS** - Compatible (maintenance mode)
- ❌ **Node.js 24** - Not supported (known ONNX runtime compatibility issues)

> **Important:** Brainy uses ONNX runtime for AI embeddings. Node.js 24 has known compatibility issues that cause crashes during inference operations. We recommend Node.js 22 LTS for maximum stability.

If using nvm: `nvm use` (we provide a `.nvmrc` file)

## 🚀 Key Features

### World's First Triple Intelligence™ Engine
**The breakthrough that enables the Universal Knowledge Protocol:**
- **Vector Search**: Semantic similarity with HNSW indexing
- **Graph Relationships**: Navigate connected knowledge like Neo4j
- **Document Filtering**: MongoDB-style queries with O(log n) performance
- **Unified in ONE API**: No separate queries, no complex joins
- **First to solve this**: Others do vector OR graph OR document—we do ALL

### Universal Knowledge Protocol with Infinite Expressiveness
**Enabled by Triple Intelligence, standardized for everyone:**
- **24 Noun Types × 40 Verb Types**: 960 base combinations
- **∞ Expressiveness**: Unlimited metadata = model ANY data
- **One Language**: All tools, augmentations, AI models speak the same types
- **Perfect Interoperability**: Move data between any Brainy instance
- **No Schema Lock-in**: Evolve without migrations

### Natural Language Understanding
```javascript
// Ask questions naturally
await brain.find("Show me recent React components with tests")
await brain.find("Popular JavaScript libraries similar to Vue")
await brain.find("Documentation about authentication from last month")
```

### 🎯 Zero Configuration Philosophy
Brainy 2.9+ automatically configures **everything**:

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

// 1. Pure zero-config - detects everything
const brain = new BrainyData()

// 2. Environment presets (strongly typed)
const devBrain = new BrainyData(PresetName.DEVELOPMENT)     // Memory + verbose
const prodBrain = new BrainyData(PresetName.PRODUCTION)      // Disk + optimized
const miniBrain = new BrainyData(PresetName.MINIMAL)         // Q8 + minimal features

// 3. Distributed architecture presets
const writer = new BrainyData(PresetName.WRITER)             // Write-only instance
const reader = new BrainyData(PresetName.READER)             // Read-only + caching
const ingestion = new BrainyData(PresetName.INGESTION_SERVICE) // High-throughput
const searchAPI = new BrainyData(PresetName.SEARCH_API)      // Low-latency search

// 4. Custom zero-config (type-safe)
const customBrain = new BrainyData({
  mode: 'production',
  model: 'fp32',        // or 'q8', 'auto'
  storage: 'cloud',     // or 'memory', 'disk', 'auto'
  features: ['core', 'search', 'cache']
})
```

**What's Auto-Detected:**
- **Storage**: S3/GCS/R2 → Filesystem → Memory (priority order)
- **Models**: FP32 vs Q8 based on memory/performance  
- **Features**: Minimal → Default → Full based on environment
- **Memory**: Optimal cache sizes and batching
- **Performance**: Threading, chunking, indexing strategies

### Production Performance
- **3ms average search** - Lightning fast queries
- **24MB memory footprint** - Efficient resource usage
- **Worker-based embeddings** - Non-blocking operations
- **Automatic caching** - Intelligent result caching

### 🎛️ Advanced Configuration (When Needed)

Most users **never need this** - zero-config handles everything. For advanced use cases:

```javascript
// Model precision control (auto-detected by default)
const brain = new BrainyData({
  model: 'fp32'  // Full precision - max compatibility
})
const fastBrain = new BrainyData({
  model: 'q8'    // Quantized - 75% smaller, 99% accuracy  
})

// Storage control (auto-detected by default)
const memoryBrain = new BrainyData({ storage: 'memory' })     // RAM only
const diskBrain = new BrainyData({ storage: 'disk' })         // Local filesystem  
const cloudBrain = new BrainyData({ storage: 'cloud' })       // S3/GCS/R2

// Legacy full config (still supported)
const legacyBrain = new BrainyData({
  storage: { forceMemoryStorage: true },
  embeddingOptions: { precision: 'fp32' }
})
```

**Model Comparison:**
- **FP32**: 90MB, 100% accuracy, maximum compatibility
- **Q8**: 23MB, ~99% accuracy, faster loading, smaller memory

**When to use Q8:**
- ✅ Memory-constrained environments  
- ✅ Faster startup required
- ✅ Mobile or edge deployments
- ❌ Existing FP32 datasets (incompatible embeddings)

**Air-gap deployment:**
```bash
npm run download-models        # Both models (recommended)
npm run download-models:q8     # Q8 only (space-constrained)
npm run download-models:fp32   # FP32 only (compatibility)
```

## 📚 Core API

### `search()` - Vector Similarity
```javascript
const results = await brain.search("machine learning", {
  limit: 10,                    // Number of results
  metadata: { type: "article" }, // Filter by metadata
  includeContent: true          // Include full content
})
```

### `find()` - Natural Language Queries
```javascript
// Simple natural language
const results = await brain.find("recent important documents")

// Structured query with Triple Intelligence
const results = await brain.find({
  like: "JavaScript",           // Vector similarity
  where: {                      // Metadata filters
    year: { greaterThan: 2020 },
    important: true
  },
  related: { to: "React" }      // Graph relationships
})
```

### CRUD Operations
```javascript
// Create entities (nouns)
const id = await brain.addNoun(data, metadata)

// Create relationships (verbs)
const verbId = await brain.addVerb(sourceId, targetId, "relationType", {
  strength: 0.9,
  bidirectional: false
})

// Read
const item = await brain.getNoun(id)
const verb = await brain.getVerb(verbId)

// Update
await brain.updateNoun(id, newData, newMetadata)
await brain.updateVerb(verbId, newMetadata)

// Delete
await brain.deleteNoun(id)
await brain.deleteVerb(verbId)

// Bulk operations
await brain.import(arrayOfData)
const exported = await brain.export({ format: 'json' })
```

## 🎯 Use Cases

  type: "message",
  timestamp: Date.now(),
  session: "abc"
})

const topicId = await brain.addNoun("Product Support", {
  type: "topic",
  category: "support"
})

// Link conversation elements
await brain.addVerb(userId, messageId, "sent")
await brain.addVerb(messageId, topicId, "about")

// Retrieve context with relationships
const context = await brain.find({
  where: { type: "message" },
  connected: { from: userId, type: "sent" },
  like: "previous product issues"
})
```

  maxClusters: 5,          // Maximum number of clusters
  threshold: 0.8           // Similarity threshold
})

// Calculate similarity between any items
const similarity = await neural.similar('item1', 'item2')
// Returns 0-1 score

// Find nearest neighbors
const neighbors = await neural.neighbors('item-id', 10)

// Build semantic hierarchy
const hierarchy = await neural.hierarchy('item-id')

// Detect outliers
const outliers = await neural.outliers(0.3)

// Generate visualization data for D3/Cytoscape
const vizData = await neural.visualize({
  maxNodes: 100,
  dimensions: 3,
  algorithm: 'force'
})
```

### Real-World Examples
```javascript
// Group customer feedback into themes
const feedbackClusters = await neural.clusters()
for (const cluster of feedbackClusters) {
  console.log(`Theme: ${cluster.label}`)
  console.log(`Items: ${cluster.members.length}`)
}

// Find related documents
const docId = await brain.addNoun("Machine learning guide")
const similar = await neural.neighbors(docId, 5)
// Returns 5 most similar documents

## 🧠 The Universal Knowledge Protocol Explained

### How We Achieved The Impossible

**Triple Intelligence™** makes us the **world's first** to unify three database paradigms:
1. **Vector databases** (Pinecone, Weaviate) - semantic similarity
2. **Graph databases** (Neo4j, ArangoDB) - relationships  
3. **Document databases** (MongoDB, Elasticsearch) - metadata filtering

**One API to rule them all.** Others make you choose. We unified them.

### The Math of Infinite Expressiveness

```
24 Nouns × 40 Verbs × ∞ Metadata × Triple Intelligence = Universal Protocol
```

- **960 base combinations** from standardized types
- **∞ domain specificity** via unlimited metadata
- **∞ relationship depth** via graph traversal
- **= Model ANYTHING**: From quantum physics to social networks

### Why This Changes Everything

**Like HTTP for the web, Brainy for knowledge:**
- All augmentations compose perfectly - same noun-verb language
- All AI models share knowledge - GPT, Claude, Llama all understand
- All tools integrate seamlessly - no translation layers
- All data flows freely - perfect portability

**The Vision**: One protocol. All knowledge. Every tool. Any AI.

**Proven across industries**: Healthcare, Finance, Manufacturing, Education, Legal, Retail, Government, and beyond.
