```

```javascript
import { createAutoBrainy, NounType, VerbType } from 'brainy'

const brainy = createAutoBrainy()

// Add data with Nouns (entities)
const catId = await brainy.add("Siamese cats are elegant and vocal", {
  noun: NounType.Thing,
  breed: "Siamese",
  category: "animal"
})

const ownerId = await brainy.add("John loves his pets", {
  noun: NounType.Person,
  name: "John Smith"
})

// Connect with Verbs (relationships)
await brainy.addVerb(ownerId, catId, {
  verb: VerbType.Owns,
  since: "2020-01-01"
})

// Search by meaning
const results = await brainy.searchText("feline companions", 5)

// Search JSON documents by specific fields
const docs = await brainy.searchDocuments("Siamese", {
  fields: ['breed', 'category'],  // Search these fields
  weights: { breed: 2.0 },         // Prioritize breed matches
  limit: 10
})

// Find relationships
const johnsPets = await brainy.getVerbsBySource(ownerId, VerbType.Owns)
```

That's it! No config, no setup, Zero-to-Smart™

### 🌐 Distributed Mode Example (NEW!)

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

// Reader Instance - Optimized for search queries
const reader = createAutoBrainy({
  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}`)
```

## 🧬 The Power of Nouns & Verbs

Brainy uses a **graph-based data model** that mirrors how humans think - with **Nouns** (entities) connected by **Verbs
** (relationships). This isn't just vectors in a void; it's structured, meaningful data.

### 📝 Nouns (What Things Are)

Nouns are your entities - the "things" in your data. Each noun has:

- A unique ID
- A vector representation (for similarity search)
- A type (Person, Document, Concept, etc.)
- Custom metadata

**Available Noun Types:**

| Category            | Types                                                             | Use For                                               |
|---------------------|-------------------------------------------------------------------|-------------------------------------------------------|
| **Core Entities**   | `Person`, `Organization`, `Location`, `Thing`, `Concept`, `Event` | People, companies, places, objects, ideas, happenings |
| **Digital Content** | `Document`, `Media`, `File`, `Message`, `Content`                 | PDFs, images, videos, emails, posts, generic content  |
| **Collections**     | `Collection`, `Dataset`                                           | Groups of items, structured data sets                 |
| **Business**        | `Product`, `Service`, `User`, `Task`, `Project`                   | E-commerce, SaaS, project management                  |
| **Descriptive**     | `Process`, `State`, `Role`                                        | Workflows, conditions, responsibilities               |

### 🔗 Verbs (How Things Connect)

Verbs are your relationships - they give meaning to connections. Not just "these vectors are similar" but "this OWNS
that" or "this CAUSES that".

**Available Verb Types:**

| Category       | Types                                                                | Examples                                 |
|----------------|----------------------------------------------------------------------|------------------------------------------|
| **Core**       | `RelatedTo`, `Contains`, `PartOf`, `LocatedAt`, `References`         | Generic relations, containment, location |
| **Temporal**   | `Precedes`, `Succeeds`, `Causes`, `DependsOn`, `Requires`            | Time sequences, causality, dependencies  |
| **Creation**   | `Creates`, `Transforms`, `Becomes`, `Modifies`, `Consumes`           | Creation, change, consumption            |
| **Ownership**  | `Owns`, `AttributedTo`, `CreatedBy`, `BelongsTo`                     | Ownership, authorship, belonging         |
| **Social**     | `MemberOf`, `WorksWith`, `FriendOf`, `Follows`, `Likes`, `ReportsTo` | Social networks, organizations           |
| **Functional** | `Describes`, `Implements`, `Validates`, `Triggers`, `Serves`         | Functions, implementations, services     |

### 💡 Why This Matters

```javascript
// Traditional vector DB: Just similarity
const similar = await vectorDB.search(embedding, 10)
// Result: [vector1, vector2, ...] - What do these mean? 🤷

// Brainy: Similarity + Meaning + Relationships
const catId = await brainy.add("Siamese cat", {
  noun: NounType.Thing,
  breed: "Siamese"
})
const ownerId = await brainy.add("John Smith", {
  noun: NounType.Person
})
await brainy.addVerb(ownerId, catId, {
  verb: VerbType.Owns,
  since: "2020-01-01"
})

// Now you can search with context!
const johnsPets = await brainy.getVerbsBySource(ownerId, VerbType.Owns)
const catOwners = await brainy.getVerbsByTarget(catId, VerbType.Owns)
```

## 🌍 Distributed Mode (New!)

Brainy now supports **distributed deployments** with multiple specialized instances sharing the same data. Perfect for
scaling your AI applications across multiple servers.

### Distributed Setup

```javascript
// Single instance (no change needed!)
const brainy = createAutoBrainy({
  storage: { s3Storage: { bucketName: 'my-bucket' } }
})

// Distributed mode requires explicit role configuration
// Option 1: Via environment variable
process.env.BRAINY_ROLE = 'writer'  // or 'reader' or 'hybrid'
const brainy = createAutoBrainy({
  storage: { s3Storage: { bucketName: 'my-bucket' } },
  distributed: true
})

// Option 2: Via configuration
const writer = createAutoBrainy({
  storage: { s3Storage: { bucketName: 'my-bucket' } },
  distributed: { role: 'writer' }  // Handles data ingestion
})

const reader = createAutoBrainy({
  storage: { s3Storage: { bucketName: 'my-bucket' } },
  distributed: { role: 'reader' }  // Optimized for queries
})

// Option 3: Via read/write mode (role auto-inferred)
const writer = createAutoBrainy({
  storage: { s3Storage: { bucketName: 'my-bucket' } },
  writeOnly: true,  // Automatically becomes 'writer' role
  distributed: true
})

const reader = createAutoBrainy({
  storage: { s3Storage: { bucketName: 'my-bucket' } },
  readOnly: true,   // Automatically becomes 'reader' role
  distributed: true
})
```

### Key Distributed Features

**🎯 Explicit Role Configuration**

- Roles must be explicitly set (no dangerous auto-assignment)
- Can use environment variables, config, or read/write modes
- Clear separation between writers and readers

**#️⃣ Hash-Based Partitioning**

- Handles multiple writers with different data types
- Even distribution across partitions
- No semantic conflicts with mixed data

**🏷️ Domain Tagging**

- Automatic domain detection (medical, legal, product, etc.)
- Filter searches by domain
- Logical separation without complexity

```javascript
// Data is automatically tagged with domains
await brainy.add({
  symptoms: "fever",
  diagnosis: "flu"
}, metadata)  // Auto-tagged as 'medical'

// Search within specific domains
const medicalResults = await brainy.search(query, 10, {
  filter: { domain: 'medical' }
})
```

**📊 Health Monitoring**

- Real-time health metrics
- Automatic dead instance cleanup
- Performance tracking

```javascript
// Get health status
const health = brainy.getHealthStatus()
// {
//   status: 'healthy',
//   role: 'reader',
//   vectorCount: 1000000,
//   cacheHitRate: 0.95,
//   requestsPerSecond: 150
// }
```

**⚡ Role-Optimized Performance**

- **Readers**: 80% memory for cache, aggressive prefetching
- **Writers**: Optimized write batching, minimal cache
- **Hybrid**: Adaptive based on workload

### Deployment Examples

**Docker Compose**

```yaml
services:
  writer:
    image: myapp
    environment:
      BRAINY_ROLE: writer  # Optional - auto-detects

  reader:
    image: myapp
    environment:
      BRAINY_ROLE: reader  # Optional - auto-detects
    scale: 5
```

**Kubernetes**

```yaml
# Automatically detects role from deployment type
apiVersion: apps/v1
kind: Deployment
metadata:
  name: brainy-readers
spec:
  replicas: 10  # Multiple readers
  template:
    spec:
      containers:
        - name: app
          image: myapp
          # Role auto-detected as 'reader' (multiple replicas)
```

**Benefits**

- ✅ **50-70% faster searches** with parallel readers
- ✅ **No coordination complexity** - Shared JSON config in S3
- ✅ **Zero downtime scaling** - Add/remove instances anytime

    startCommand: node server.js
    envVars:
      - key: BRAINY_STORAGE
        value: persistent-disk
```

## 🚀 Quick Examples

### Basic Usage

```javascript
import { BrainyData, NounType, VerbType } from 'brainy'

// Initialize
const db = new BrainyData()
await db.init()

// Add data (automatically vectorized)
const catId = await db.add("Cats are independent pets", {
  noun: NounType.Thing,
  category: 'animal'
})

// Search for similar items
const results = await db.searchText("feline pets", 5)

// Add relationships
await db.addVerb(catId, dogId, {
  verb: VerbType.RelatedTo,
  description: 'Both are pets'
})
```

### AutoBrainy (Recommended)

```javascript
import { createAutoBrainy } from 'brainy'

// Everything auto-configured!
const brainy = createAutoBrainy()

// Just start using it
await brainy.addVector({ id: '1', vector: [0.1, 0.2, 0.3], text: 'Hello' })
const results = await brainy.search([0.1, 0.2, 0.3], 10)
```

### Scenario-Based Setup

```javascript
import { createQuickBrainy } from 'brainy'

// Choose your scale: 'small', 'medium', 'large', 'enterprise'
const brainy = await createQuickBrainy('large', {
  bucketName: 'my-vector-db'
})
```

### With Offline Models

```javascript
import { createAutoBrainy } from 'brainy'
import { BundledUniversalSentenceEncoder } from '@soulcraft/brainy-models'

// Use bundled model for offline operation
const brainy = createAutoBrainy({
  embeddingModel: BundledUniversalSentenceEncoder,
  // Model loads from local files, no network needed!
})

// Works exactly the same, but 100% offline
await brainy.add("This works without internet!", {
  noun: NounType.Content
})
```
