+# 🔌 Brainy 2.0 Augmentations Complete Reference
+
+> **All 27 augmentations that power Brainy's extensibility - with locations, usage, and examples**
+
+## Quick Start
+
+```typescript
+import { BrainyData } from '@soulcraft/brainy'
+
+const brain = new BrainyData({
+  // Augmentations auto-configure based on environment
+  storage: 'auto',     // Storage augmentation
+  cache: true,         // Cache augmentation
+  index: true          // Index augmentation
+})
+
+await brain.init()  // Augmentations initialize automatically
+```
+
+## Core Concepts
+
+### What are Augmentations?
+Augmentations are modular extensions that add functionality to Brainy without cluttering the core API. They follow a unified interface and can be:
+- **Auto-enabled**: Based on configuration (cache, index, storage)
+- **Manually registered**: For custom functionality
+- **Chained**: Multiple augmentations work together seamlessly
+
+### Augmentation Lifecycle
+1. **Registration**: Augmentations register before init()
+2. **Initialization**: Two-phase init (storage first, then others)
+3. **Execution**: Hook into operations (before/after/both)
+4. **Shutdown**: Clean teardown on brain.shutdown()
+

+  // These auto-register augmentations:
+  storage: 'auto',        // Storage augmentation
+  cache: true,           // Cache augmentation  
+  index: true,           // Index augmentation
+  wal: true,            // WAL augmentation
+  metrics: true         // Metrics augmentation
+})
+```
+
+### Manual Registration
+```typescript
+const brain = new BrainyData()
+
+// Register before init()
+const customAug = new MyCustomAugmentation()
+await brain.registerAugmentation(customAug)
+
+await brain.init()
+```
+
+### Creating Custom Augmentations
+```typescript
+import { BaseAugmentation } from '@soulcraft/brainy'
+
+class MyAugmentation extends BaseAugmentation {
+  readonly name = 'my-augmentation'
+  readonly timing = 'after'  // before | after | both
+  readonly operations = ['addNoun', 'search']  // Which ops to hook
+  readonly priority = 10      // Execution order (lower = earlier)
+  
+  protected async onInit(): Promise<void> {
+    // Initialize your augmentation
+  }
+  
+  async execute<T>(
+    operation: string,
+    params: any,
+    context?: AugmentationContext
+  ): Promise<T | void> {
+    // Your augmentation logic
+    if (operation === 'addNoun') {
+      console.log('Noun added:', params)
+    }
+  }
+  
+  protected async onShutdown(): Promise<void> {
+    // Cleanup
+  }
+}
+```
+
+---
+
+## Augmentation Timing & Priority
+
+### Timing Options
+- **`before`**: Runs before the operation (can modify params)
+- **`after`**: Runs after the operation (can see results)
+- **`both`**: Runs before AND after
+
+### Priority (lower = earlier)
+1. Storage augmentations (priority: 0)
+2. Cache/Index augmentations (priority: 5-10)
+3. Monitoring/Metrics (priority: 15-20)
+4. Conduits/Synapses (priority: 20-30)
+
+---
+
+## Key Integration Points
+
+### Where Augmentations Hook In
+
+**BrainyData Constructor**:
+- Storage augmentations register based on config
+- Cache/Index augmentations auto-register if enabled
+
+**brain.init()**:
+- Two-phase initialization (storage first, then others)
+- Augmentations can access brain instance via context
+
+**Operations** (addNoun, search, etc.):
+- Augmentations execute based on timing and operations filter
+- Can modify params (before) or see results (after)
+
+**brain.shutdown()**:
+- All augmentations cleaned up in reverse order
+
+---
+
+## Performance Impact
+
+Most augmentations have minimal overhead:
+- **Cache**: ~1ms per search (saves 10-100ms on hits)
+- **Index**: ~1ms per operation (saves 100ms+ on queries)
+- **Metrics**: <1ms per operation
+- **Storage**: Varies by adapter (memory: 0ms, S3: 50-200ms)
+
+---
+
+## Best Practices
+
+1. **Let auto-configuration work**: Most apps need zero manual config
+2. **Storage first**: Always configure storage before other augmentations
+3. **Use built-in augmentations**: They're optimized and battle-tested
+4. **Custom augmentations**: Extend BaseAugmentation for consistency
+5. **Respect timing**: Use 'before' to modify, 'after' to observe
+6. **Mind priority**: Lower numbers execute first
+
+---
+
+## Troubleshooting
+
+### Augmentation not working?
+```typescript
+// Check if registered
+brain.listAugmentations()
+
+// Check if enabled
+brain.isAugmentationEnabled('cache')
+
+// Enable/disable at runtime
+brain.enableAugmentation('cache')
+brain.disableAugmentation('cache')
+```
+
+### Performance issues?
+```typescript
+// Check augmentation overhead
+const stats = brain.getStatistics()
+console.log(stats.augmentations)
+
+// Disable non-critical augmentations
+brain.disableAugmentation('monitoring')
+```

+# 🛠️ Brainy Augmentation Developer Guide
+
+> **How to create, test, and use augmentations in Brainy 2.0**
+
+## Quick Start: Your First Augmentation
+
+```typescript
+import { BaseAugmentation, BrainyAugmentation, AugmentationContext } from '@soulcraft/brainy'
+
+export class MyFirstAugmentation extends BaseAugmentation {
+  readonly name = 'my-first-augmentation'
+  readonly timing = 'after' as const       // When to run: before | after | both
+  readonly operations = ['addNoun'] as const  // Which operations to hook
+  readonly priority = 10                    // Execution order (lower = first)
+  
+  protected async onInit(): Promise<void> {
+    // Initialize your augmentation
+    console.log('MyFirstAugmentation initialized!')
+  }
+  
+  async execute<T = any>(
+    operation: string,
+    params: any,
+    context?: AugmentationContext
+  ): Promise<T | void> {
+    // Your augmentation logic
+    if (operation === 'addNoun') {
+      console.log('Noun added:', params.noun)
+      // You can access the brain instance
+      const stats = await context?.brain.getStatistics()
+      console.log('Total nouns:', stats.totalNouns)
+    }
+  }
+  
+  protected async onShutdown(): Promise<void> {
+    // Cleanup
+    console.log('MyFirstAugmentation shutting down')
+  }
+}
+```
+
+## Using Your Augmentation
+
+```typescript
+import { BrainyData } from '@soulcraft/brainy'
+import { MyFirstAugmentation } from './my-first-augmentation'
+
+const brain = new BrainyData()
+
+// Register before init()
+brain.augmentations.register(new MyFirstAugmentation())
+
+await brain.init()
+
+// Now your augmentation runs automatically!
+await brain.addNoun('Hello World')
+// Console: "Noun added: { id: '...', vector: [...], metadata: {} }"
+```
+
+---
+
+## Augmentation Lifecycle
+
+### 1. Registration Phase
+```typescript
+const aug = new MyAugmentation()
+brain.augmentations.register(aug)  // Before brain.init()!
+```
+
+### 2. Initialization Phase
+```typescript
+await brain.init()  // Calls aug.initialize() internally
+// Your onInit() method runs here
+```
+
+### 3. Execution Phase
+```typescript
+await brain.addNoun('data')  // Your execute() method runs
+```
+
+### 4. Shutdown Phase
+```typescript
+await brain.shutdown()  // Your onShutdown() method runs
+```
+
+---
+
+## Timing Options
+
+### `before` - Modify Input
+```typescript
+class ValidationAugmentation extends BaseAugmentation {
+  readonly timing = 'before' as const
+  
+  async execute<T>(operation: string, params: any): Promise<any> {
+    if (operation === 'addNoun') {
+      // Validate and/or modify params
+      if (!params.content) {
+        throw new Error('Content required')
+      }
+      // Return modified params
+      return { ...params, validated: true }
+    }
+  }
+}
+```
+
+### `after` - React to Results
+```typescript
+class LoggingAugmentation extends BaseAugmentation {
+  readonly timing = 'after' as const
+  
+  async execute<T>(operation: string, params: any): Promise<void> {
+    if (operation === 'search') {
+      console.log(`Search for "${params.query}" returned ${params.result.length} results`)
+    }
+    // Don't return anything - just observe
+  }
+}
+```
+
+### `both` - Before AND After
+```typescript
+class TimingAugmentation extends BaseAugmentation {
+  readonly timing = 'both' as const
+  private startTime?: number
+  
+  async execute<T>(operation: string, params: any, context?: AugmentationContext): Promise<void> {
+    if (!this.startTime) {
+      // Before execution
+      this.startTime = Date.now()
+    } else {
+      // After execution
+      const duration = Date.now() - this.startTime
+      console.log(`${operation} took ${duration}ms`)
+      this.startTime = undefined
+    }
+  }
+}
+```
+
+---
+
+## Operation Hooks
+
+### Core Operations You Can Hook
+```typescript
+readonly operations = [
+  'addNoun',        // Adding data
+  'updateNoun',     // Updating data
+  'deleteNoun',     // Deleting data
+  'getNoun',        // Retrieving data
+  'search',         // Searching
+  'find',           // Triple Intelligence queries
+  'addVerb',        // Adding relationships
+  'deleteVerb',     // Removing relationships
+  'clear',          // Clearing data
+  'all'            // Hook ALL operations
+] as const
+```
+
+### Example: Multi-Operation Hook
+```typescript
+class AuditAugmentation extends BaseAugmentation {
+  readonly operations = ['addNoun', 'updateNoun', 'deleteNoun'] as const
+  
+  async execute<T>(operation: string, params: any): Promise<void> {
+    // Log all data modifications
+    await this.logToAuditTrail(operation, params)
+  }
+}
+```
+
+---
+
+## Accessing Brain Context
+
+```typescript
+class ContextAwareAugmentation extends BaseAugmentation {
+  async execute<T>(
+    operation: string,
+    params: any,
+    context?: AugmentationContext
+  ): Promise<void> {
+    // Access the brain instance
+    const brain = context?.brain
+    if (!brain) return
+    
+    // Use any brain method
+    const stats = await brain.getStatistics()
+    const size = await brain.size()
+    const results = await brain.search('query')
+    
+    // Access other augmentations
+    const cache = brain.augmentations.get('cache')
+    if (cache) {
+      await cache.clear()
+    }
+  }
+}
+```
+
+---
+
+## Real-World Examples

+
+## Best Practices
+
+### 1. Use Proper Timing
+- `before`: Validation, modification, rate limiting
+- `after`: Logging, metrics, side effects
+- `both`: Timing, tracing, wrapping
+
+### 2. Set Appropriate Priority
+```typescript
+// Priority guidelines
+100: Critical (auth, rate limiting)
+50:  Important (validation, transformation)
+10:  Normal (logging, metrics)
+1:   Optional (debugging, tracing)
+```
+
+### 3. Handle Errors Gracefully
+```typescript
+async execute<T>(operation: string, params: any): Promise<void> {
+  try {
+    await this.riskyOperation()
+  } catch (error) {
+    // Log but don't break the main operation
+    console.error(`Augmentation error in ${this.name}:`, error)
+    // Optionally report to monitoring
+    this.reportError(error)
+  }
+}
+```
+
+### 4. Be Performance Conscious
+```typescript
+class CachedAugmentation extends BaseAugmentation {
+  private cache = new Map<string, any>()
+  
+  async execute<T>(operation: string, params: any): Promise<any> {
+    const key = this.getCacheKey(params)
+    
+    // Check cache first
+    if (this.cache.has(key)) {
+      return this.cache.get(key)
+    }
+    
+    // Expensive operation
+    const result = await this.expensiveOperation(params)
+    this.cache.set(key, result)
+    
+    return result
+  }
+}
+```
+
+### 5. Clean Up Resources
+```typescript
+protected async onShutdown(): Promise<void> {
+  // Close connections
+  await this.connection?.close()
+  
+  // Clear intervals
+  clearInterval(this.interval)
+  
+  // Flush buffers
+  await this.flush()
+  
+  // Clear caches
+  this.cache.clear()
+}
+```

+
+### Q: Can augmentations communicate?
+**A**: Yes, through the context: `context.brain.augmentations.get('other-augmentation')`
+
+### Q: What if my augmentation fails?
+**A**: Handle errors internally. Don't break the main operation unless critical.
+
+### Q: Can I use async operations?
+**A**: Yes, everything is async-friendly.
+
+### Q: How do I access storage directly?
+**A**: Through context: `context.brain.storage` (but prefer using brain methods)

+# Brainy Augmentations
+
+Augmentations are the core extensibility mechanism in Brainy. They allow you to modify, enhance, and extend Brainy's behavior without changing the core code.
+
+## Core Principle: One Interface, Infinite Possibilities
+
+Every augmentation implements the same simple `BrainyAugmentation` interface:
+
+```typescript
+interface BrainyAugmentation {
+  name: string
+  timing: 'before' | 'after' | 'around' | 'replace'
+  operations: string[]
+  priority: number
+  initialize(context): Promise<void>
+  execute(operation, params, next): Promise<any>
+}
+```
+
+This single interface can handle EVERYTHING - from adding AI capabilities to exposing APIs to replacing storage backends.

+
+## Using Augmentations
+
+### Zero-Config Approach
+
+```typescript
+const brain = new BrainyData()
+
+// Just register augmentations - they work automatically!
+brain.augmentations.register(new WALAugmentation())
+brain.augmentations.register(new EntityRegistryAugmentation())
+brain.augmentations.register(new APIServerAugmentation())
+
+await brain.init()
+```
+
+### With Configuration
+
+```typescript
+const brain = new BrainyData()
+
+brain.augmentations.register(
+  new APIServerAugmentation({
+    port: 8080,
+    auth: { required: true }
+  })
+)
+
+await brain.init()
+```
+
+## Creating Custom Augmentations
+
+See [Creating Custom Augmentations](./creating-augmentations.md) for a complete guide.
+
+Quick example:
+
+```typescript
+class MyAugmentation extends BaseAugmentation {
+  readonly name = 'my-augmentation'
+  readonly timing = 'after'
+  readonly operations = ['add', 'search']
+  readonly priority = 50
+  
+  async execute<T>(operation: string, params: any, next: () => Promise<T>): Promise<T> {
+    console.log(`Before ${operation}`)
+    const result = await next()
+    console.log(`After ${operation}`)
+    return result
+  }
+}
+```
+
+## Augmentation Timing
+
+### `before`
+Executes before the main operation. Used for:
+- Input validation
+- Data transformation
+- Authentication checks
+
+### `after`
+Executes after the main operation. Used for:
+- Broadcasting updates
+- Syncing to external services
+- Logging and metrics
+
+### `around`
+Wraps the main operation. Used for:
+- Transactions
+- Caching
+- Error handling
+
+### `replace`
+Completely replaces the main operation. Used for:
+- Alternative storage backends
+- Mock implementations
+- Proxy operations
+
+## Priority System
+
+Higher numbers execute first:
+- **100**: Critical system operations
+- **50**: Performance optimizations
+- **10**: Enhancement features
+- **1**: Optional features

+# API Server Augmentation
+
+## Overview
+
+The `APIServerAugmentation` is a powerful augmentation that exposes your Brainy instance through REST, WebSocket, and MCP (Model Context Protocol) APIs. It transforms Brainy into a full-featured API server with zero configuration required.
+
+## Features
+
+### 🌐 REST API
+Complete CRUD operations and advanced queries through HTTP endpoints.
+
+### 🔌 WebSocket Server
+Real-time bidirectional communication with automatic operation broadcasting.
+
+### 🧠 MCP Integration
+Built-in Model Context Protocol support for AI agent communication.
+
+### 📊 Operation Broadcasting
+Automatically broadcasts all Brainy operations to subscribed WebSocket clients.
+
+### 🔒 Optional Security
+Built-in authentication and rate limiting when needed.
+
+## Installation
+
+The APIServerAugmentation is included in Brainy core. No additional installation required.
+
+For Node.js environments, you may want to install optional dependencies:
+```bash
+npm install express cors ws
+```
+
+## Zero-Config Usage
+
+```typescript
+import { BrainyData } from 'brainy'
+import { APIServerAugmentation } from 'brainy/augmentations'
+
+const brain = new BrainyData()
+
+// Register the API server augmentation
+brain.augmentations.register(new APIServerAugmentation())
+
+await brain.init()
+
+// Server is now running at http://localhost:3000
+console.log('API Server ready!')
+console.log('REST: http://localhost:3000/api/*')
+console.log('WebSocket: ws://localhost:3000/ws')
+console.log('MCP: http://localhost:3000/api/mcp')
+```
+
+## Configuration Options
+
+While zero-config works great, you can customize the server:
+
+```typescript
+const apiServer = new APIServerAugmentation({
+  enabled: true,           // Enable/disable the server
+  port: 3000,             // HTTP port
+  host: '0.0.0.0',        // Bind address
+  
+  cors: {
+    origin: '*',          // CORS allowed origins
+    credentials: true     // Allow credentials
+  },
+  
+  auth: {
+    required: false,      // Require authentication
+    apiKeys: [],         // Valid API keys
+    bearerTokens: []     // Valid bearer tokens
+  },
+  
+  rateLimit: {
+    windowMs: 60000,     // Rate limit window (ms)
+    max: 100            // Max requests per window
+  }
+})
+```
+
+## REST API Endpoints
+
+### Health Check
+```http
+GET /health
+```
+Returns server status and basic metrics.
+
+### Search
+```http
+POST /api/search
+Content-Type: application/json
+
+{
+  "query": "search text",
+  "limit": 10,
+  "options": {}
+}
+```
+
+### Add Data
+```http
+POST /api/add
+Content-Type: application/json
+
+{
+  "content": "data to add",
+  "metadata": {
+    "key": "value"
+  }
+}
+```
+
+### Get by ID
+```http
+GET /api/get/:id
+```
+
+### Delete
+```http
+DELETE /api/delete/:id
+```
+
+### Create Relationship
+```http
+POST /api/relate
+Content-Type: application/json
+
+{
+  "source": "id1",
+  "target": "id2",
+  "verb": "relates_to",
+  "metadata": {}
+}
+```
+
+### Complex Queries
+```http
+POST /api/find
+Content-Type: application/json
+
+{
+  "where": { "type": "document" },
+  "like": "machine learning",
+  "limit": 10
+}
+```
+
+### Clustering
+```http
+POST /api/cluster
+Content-Type: application/json
+
+{
+  "algorithm": "kmeans",
+  "options": {
+    "k": 5
+  }
+}
+```
+
+### Statistics
+```http
+GET /api/stats
+```
+
+### Operation History
+```http
+GET /api/history
+```
+
+## WebSocket API
+
+### Connection
+```javascript
+const ws = new WebSocket('ws://localhost:3000/ws')
+
+ws.onopen = () => {
+  console.log('Connected to Brainy WebSocket')
+}
+
+ws.onmessage = (event) => {
+  const msg = JSON.parse(event.data)
+  console.log('Received:', msg)
+}
+```
+
+### Subscribe to Operations
+```javascript
+ws.send(JSON.stringify({
+  type: 'subscribe',
+  operations: ['all']  // or specific: ['add', 'search', 'delete']
+}))
+```
+
+### Search via WebSocket
+```javascript
+ws.send(JSON.stringify({
+  type: 'search',
+  query: 'your search',
+  limit: 10,
+  requestId: 'unique-id'
+}))
+```
+
+### Add Data via WebSocket
+```javascript
+ws.send(JSON.stringify({
+  type: 'add',
+  content: 'data to add',
+  metadata: {},
+  requestId: 'unique-id'
+}))
+```
+
+### Operation Broadcasts
+When subscribed, you'll receive real-time updates:
+```javascript
+{
+  "type": "operation",
+  "operation": "add",
+  "params": { /* sanitized parameters */ },
+  "timestamp": 1234567890,
+  "duration": 15
+}
+```
+
+## MCP (Model Context Protocol)
+
+The MCP endpoint allows AI agents to interact with Brainy:
+
+```http
+POST /api/mcp
+Content-Type: application/json
+
+{
+  "method": "search",
+  "params": {
+    "query": "find documents about AI"
+  }
+}
+```
+
+## Authentication
+
+When authentication is enabled:
+
+### API Key
+```http
+GET /api/stats
+X-API-Key: your-api-key
+```
+
+### Bearer Token
+```http
+GET /api/stats
+Authorization: Bearer your-token
+```
+
+## Environment Support
+
+### Node.js ✅
+Full support with Express, WebSocket, and all features.
+
+### Deno 🚧
+Planned support using Deno.serve() or oak framework.
+
+### Browser/Service Worker 🚧
+Planned support for intercepting fetch() calls locally.
+
+## How It Works
+
+The APIServerAugmentation hooks into Brainy's augmentation pipeline:
+
+1. **Timing**: Executes `after` operations complete
+2. **Operations**: Monitors `all` operations
+3. **Broadcasting**: Sends operation details to subscribed clients
+4. **History**: Maintains operation history (last 1000 operations)
+
+## Example: Multi-Client Sync
+
+```typescript
+// Server
+const brain = new BrainyData()
+brain.augmentations.register(new APIServerAugmentation())
+await brain.init()
+
+// Client 1 - WebSocket subscriber
+const ws1 = new WebSocket('ws://localhost:3000/ws')
+ws1.onopen = () => {
+  ws1.send(JSON.stringify({
+    type: 'subscribe',
+    operations: ['add', 'delete']
+  }))
+}
+ws1.onmessage = (e) => {
+  console.log('Client 1 received update:', JSON.parse(e.data))
+}
+
+// Client 2 - REST API user
+fetch('http://localhost:3000/api/add', {
+  method: 'POST',
+  headers: { 'Content-Type': 'application/json' },
+  body: JSON.stringify({
+    content: 'New data',
+    metadata: { source: 'client2' }
+  })
+})
+// Client 1 automatically receives notification!
+```
+
+## Performance Considerations
+
+- **Operation History**: Limited to last 1000 operations
+- **WebSocket Heartbeat**: Every 30 seconds
+- **Client Timeout**: 60 seconds of inactivity
+- **Parameter Sanitization**: Sensitive fields removed, large content truncated
+- **Rate Limiting**: In-memory tracking (use Redis in production)
+
+## Security Notes
+
+1. **Default Configuration**: No auth, open CORS - suitable for development
+2. **Production**: Enable auth, configure CORS, use HTTPS
+3. **Sensitive Data**: Parameters are sanitized before broadcasting
+4. **Rate Limiting**: Basic in-memory implementation included
+
+## Comparison with Previous Implementations
+
+The APIServerAugmentation unifies and replaces:
+- `BrainyMCPBroadcast` - Node-specific WebSocket/HTTP server
+- `WebSocketConduitAugmentation` - WebSocket client functionality  
+- `ServerSearchAugmentations` - Remote Brainy connections
+
+Benefits of the unified approach:
+- Single augmentation for all API needs
+- Consistent interface across protocols
+- Automatic operation broadcasting
+- Environment-aware implementation
+- Zero-configuration philosophy
+
+## Advanced Usage
+
+### Custom Operation Filtering
+
+```typescript
+class FilteredAPIServer extends APIServerAugmentation {
+  shouldExecute(operation: string, params: any): boolean {
+    // Don't broadcast sensitive operations
+    if (operation === 'delete' && params.sensitive) {
+      return false
+    }
+    return true
+  }
+}
+```
+
+### Integration with Other Augmentations
+
+```typescript
+const brain = new BrainyData()
+
+// Stack augmentations for complete system
+brain.augmentations.register(new WALAugmentation())           // Durability
+brain.augmentations.register(new EntityRegistryAugmentation()) // Dedup
+brain.augmentations.register(new APIServerAugmentation())      // API
+
+await brain.init()
+// All augmentations work together seamlessly!
+```
+
+## Troubleshooting
+
+### Server won't start
+- Check if port is already in use
+- Verify Node.js dependencies are installed: `npm install express cors ws`
+- Check console for error messages
+
+### WebSocket connections drop
+- Ensure heartbeat responses are handled
+- Check for proxy/firewall issues
+- Verify CORS configuration
+
+### Authentication not working
+- Ensure `auth.required` is set to `true`
+- Verify API keys or bearer tokens are correctly configured
+- Check request headers are properly formatted
+
+## Future Enhancements
+

+- [ ] Service Worker implementation  
+- [ ] GraphQL endpoint
+- [ ] gRPC support
+- [ ] Built-in SSL/TLS
+- [ ] Redis-based rate limiting
