## 🎯 Features

### 🕐 Memory Version Control (NEW!)

- ✅ Automatic versioning on updates
- ✅ Complete version history
- ✅ Rollback to any version
- ✅ Version diff comparison
- ✅ Automatic cleanup of old versions

```typescript
// Create memory (v1)
const id = await memoryManager.store('Initial', ['test']);

// Update (v2)
await memoryManager.updateMemory(id, 'Updated', 'user', 'Reason');

// View history
const history = await memoryManager.getVersionHistory(id);

// Rollback
await memoryManager.rollbackMemory(id, 1);
```

### 🔐 4-Level Permission System

- 🟢 **SAFE** - Read operations, no confirmation needed
- 🟡 **MODERATE** - Write operations, auto-approve in trusted sessions
- 🟠 **DANGEROUS** - Delete/Execute, always requires confirmation
- 🔴 **DESTRUCTIVE** - Irreversible operations, explicit CONFIRM required

### ✅ Zod Parameter Validation

All tools use Zod schemas for type-safe parameter validation:

```typescript
import { z } from 'zod';

const readSchema = z.object({
  path: z.string(),
  limit: z.number().min(1).max(10000).optional()
});
```

### 💬 Confirmation Dialogs

Dangerous operations automatically show confirmation dialogs:

```
🟠 Permission Required

Operation: exec
Risk Level: DANGEROUS
Parameters: { "command": "rm -rf /tmp" }

⚠️ This operation may be dangerous

Reply y to confirm, n to cancel.
```

### 📝 Audit Logging

All DANGEROUS+ operations are automatically logged:

```markdown
#### 🟠 2026-04-01 09:30:15
- **Operation**: `exec`
- **Risk Level**: DANGEROUS
- **Session**: main-session
- **User Confirmed**: ✅ Yes
- **Result**: ✅ Success
```

### 🧠 Memory Management with Hotness

- Automatic hotness scoring (0-100)
- Daily decay algorithm
- Smart recall based on relevance
- Cold/hot data separation

### 🔍 Vector Search (OpenViking)

- Semantic similarity search
- 1024-dimensional embeddings
- Cosine similarity calculation
- Fallback to text search

---

## 🚀 Quick Start

### Basic Usage

```typescript
import {
  executeToolWithPermission,
  defaultMemoryManager,
  PermissionLevel
} from '@openclaw/enhanced-permissions';

// Execute tool with permission check
const result = await executeToolWithPermission('read', {
  path: 'file.txt',
  limit: 100
}, 'main-session');

// Manage memories
const memId = await defaultMemoryManager.store(
  'User prefers TypeScript',
  ['preference', 'coding']
);

// Recall memories
const memories = await defaultMemoryManager.recall('coding', {
  limit: 5,
  minHotness: 20
});
```

### Advanced Usage

#### Custom Permission Checker

```typescript
import { PermissionChecker, PermissionLevel } from '@openclaw/enhanced-permissions';

const checker = new PermissionChecker({
  userLevel: PermissionLevel.DANGEROUS,
  requireConfirm: PermissionLevel.MODERATE,
  trustedSessions: ['main-session', 'home-workspace']
});

// Check permission
const result = await checker.check('exec', {
  sessionId: 'main',
  operation: 'exec',
  params: { command: 'ls -la' },
  timestamp: Date.now()
});

if (result.requiresConfirm) {
  console.log(result.confirmMessage);
  // Wait for user confirmation...
}
```

#### Vector Search with OpenViking

```typescript
import { defaultOpenVikingService } from '@openclaw/enhanced-permissions';

// Configure API key
defaultOpenVikingService.setApiKey('YOUR_VOLCENGINE_API_KEY');

// Generate embedding
const embedding = await defaultOpenVikingService.generateEmbedding(
  'Text to embed'
);

// Find similar memories
const similar = await defaultOpenVikingService.findSimilarMemories(
  'coding preferences',
  memories,
  5
);
```

## 📚 API Reference

### PermissionChecker

```typescript
class PermissionChecker {
  constructor(options: {
    userLevel: PermissionLevel;
    requireConfirm: PermissionLevel;
    trustedSessions: string[];
  });
  
  check(operation: string, context: OperationContext): Promise<PermissionResult>;
}
```

### ToolRegistry

```typescript
class ToolRegistry {
  register(tool: Tool): void;
  execute(toolName: string, params: any, context?: any): Promise<ToolResult>;
  getCachedSchema(toolName: string): string | undefined;
  getSchemaCacheSavings(): number;
}
```

### MemoryManager

```typescript
class MemoryManager {
  store(content: string, tags: string[]): Promise<string>;
  recall(query: string, options: RecallOptions): Promise<Memory[]>;
  touchMemory(id: string): void;
  archiveColdMemories(): Memory[];
  getStats(): MemoryStats;
}
```

### OpenVikingService

```typescript
class OpenVikingService {
  isAvailable(): boolean;
  generateEmbedding(text: string): Promise<number[]>;
  findSimilarMemories(query: string, memories: Memory[], limit: number): Promise<Array<{id: string, score: number}>>;
  setApiKey(apiKey: string): void;
}
```
