✅ **Distributed Consensus** - No single point of failure
✅ **Quantum-Resistant** - Future-proof security
✅ **Auto-Resolution** - Smart conflict handling
✅ **High Performance** - 1,000+ ops/sec

## Quick Start

```javascript
const { JjWrapper } = require('agentic-jujutsu');

async function example() {
    const jj = new JjWrapper();

    // 1. Enable coordination
    jj.enableAgentCoordination();

    // 2. Register agents
    await jj.registerAgent('coder-1', 'coder');
    await jj.registerAgent('coder-2', 'coder');

    // 3. Check for conflicts before executing
    const conflictsJson = await jj.checkAgentConflicts(
        operationId,
        ['src/main.js']
    );
    const conflicts = JSON.parse(conflictsJson);

    if (conflicts.length === 0) {
        // Safe to proceed
        await jj.execute(operation);
    } else {
        // Handle conflicts
        console.log(`Conflicts: ${conflicts.length}`);
    }

    // 4. Register operation in DAG
    await jj.registerAgentOperation(
        'coder-1',
        operationId,
        ['src/main.js']
    );

    // 5. Get stats
    const stats = JSON.parse(await jj.getCoordinationStats());
    console.log(`Active agents: ${stats.activeAgents}`);
}
```

## Conflict Detection

### Severity Levels

| Level | Description | Action |
|-------|-------------|--------|
| **0 - None** | Different files | ✅ Execute immediately |
| **1 - Minor** | Can auto-merge | ⚡ Auto-merge |
| **2 - Moderate** | Needs review | ⏱️ Sequential execution |
| **3 - Severe** | Manual required | 🛑 Wait for resolution |

### Detection Algorithm

```
1. File-level check
   ↓
2. Operation type compatibility
   ↓
3. Exclusive pattern matching
   ↓
4. Semantic analysis
   ↓
5. Assign severity & resolution strategy
```

## Demo Results

```bash
$ node examples/multi-agent-demo.js

Scenario 1: No Conflicts (Different Files)
  ✅ coder-1: edit completed
  ✅ coder-2: edit completed
  📊 Total operations: 2

Scenario 2: Minor Conflict (Same Branch)
  ✅ coder-1: branch-create completed
  ⏱️ coder-2: Sequential execution
  ✅ coder-2: branch-create completed
  📊 Total operations: 2

Scenario 3: Severe Conflict (Same Files)
  ✅ coder-1: edit completed
  🛑 coder-2: Manual resolution required
  ✅ coder-2: edit completed (after resolution)
  📊 Total operations: 2

Scenario 4: Complex Workflow
  Stage 1: Parallel development (2 agents)
  Stage 2: Code review (1 agent)
  Stage 3: Testing (1 agent)
  📊 Total agents: 4
  📊 Total operations: 4
```

## API Reference

### Core Methods

```typescript
// Enable coordination
jj.enableAgentCoordination(): void

// Register agent
jj.registerAgent(agentId: string, agentType: string): Promise<void>

// Register operation in DAG
jj.registerAgentOperation(
  agentId: string,
  operationId: string,
  affectedFiles: string[]
): Promise<string>

// Check for conflicts
jj.checkAgentConflicts(
  operationId: string,
  affectedFiles: string[]
): Promise<string> // JSON array of AgentConflict

// Get coordination tips
jj.getCoordinationTips(): Promise<string[]>

// Get agent stats
jj.getAgentStats(agentId: string): Promise<string> // JSON AgentStats

// List all agents
jj.listAgents(): Promise<string> // JSON array of AgentStats

// Get system stats
jj.getCoordinationStats(): Promise<string> // JSON CoordinationStats
```

### Data Types

```typescript
interface AgentConflict {
  operationA: string;
  operationB: string;
  agents: string[];
  conflictingResources: string[];
  severity: number;
  description: string;
  resolutionStrategy: string;
}

interface AgentStats {
  agentId: string;
  agentType: string;
  operationsCount: number;
  reputation: number;
  lastSeen: string; // ISO 8601
}

interface CoordinationStats {
  totalAgents: number;
  activeAgents: number;

## Use Cases

### 1. Parallel Development
Multiple AI agents work on different features simultaneously without conflicts.

```javascript
await Promise.all([
  agent1.implement('feature/auth'),
  agent2.implement('feature/api'),
  agent3.implement('feature/ui'),
]);
// ✅ No conflicts - different files
```

### 2. Sequential Coordination
Agents automatically coordinate when working on related code.

```javascript
await agent1.edit('src/main.js');
// Agent 2 waits automatically if conflict detected
await agent2.edit('src/main.js');
// ⏱️ Sequential execution enforced
```

### 3. Reviewer Integration
Code review agent checks for conflicts before reviewing.

```javascript
const conflicts = await jj.checkAgentConflicts(
  reviewOperation,
  ['src/auth.js', 'src/api.js']
);

if (conflicts.length > 0) {
  console.log('Wait for changes to finalize');
} else {
  await reviewer.review();
}
```

### 4. Test Orchestration
Testing agent coordinates with development agents.

```javascript
// Wait for all development to complete
const tips = await jj.getCoordinationTips();

if (tips.length === 0) {
  // All agents have finished
  await tester.runTests();
}
```
