## 📦 What's New

### 1. Multi-Agent Coordination System

**Enable real-time coordination between multiple AI agents working on the same codebase.**

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

const wrapper = new JjWrapper();
await wrapper.enableAgentCoordination();

// Register agents
await wrapper.registerAgent('coder-1', 'coder');
await wrapper.registerAgent('reviewer-1', 'reviewer');

// Check for conflicts before operations
const conflicts = await wrapper.checkAgentConflicts(
  'edit-operation',
  'edit',
  ['src/main.rs']
);

if (conflicts.length > 0) {
  console.log('Conflicts detected:', conflicts[0].description);
  console.log('Resolution:', conflicts[0].resolution_strategy);
}

// Get agent statistics
const stats = await wrapper.getAgentStats('coder-1');
console.log(`Agent ${stats.agent_id}: ${stats.operations_count} operations`);
```

**Features:**
- Agent registration and tracking

- Agent reputation scoring (0.0-1.0)
- Coordination statistics and monitoring
- <2ms overhead per operation

### 2. QuantumDAG Distributed Consensus

**Integrate with @qudag/napi-core for distributed agent consensus using quantum-resistant cryptography.**

```javascript

const wrapper = new JjWrapper();
await wrapper.enableAgentCoordination();

// Create quantum bridge for QuantumDAG integration
const bridge = createQuantumBridge(wrapper);
await bridge.initialize();

// Register operations in the DAG
const vertexId = await bridge.registerOperation(
  operation.id,
  operation,
  ['src/file.rs']
);

// Check for DAG-based conflicts
const dagConflicts = await bridge.checkConflicts(
  'new-op-id',
  'edit',
  ['src/file.rs']
);

// Get DAG tips for coordination
const tips = await bridge.getTips();
console.log('Current DAG tips:', tips.length);
```

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

// Generate quantum-resistant keypair
const keypair = QuantumSigner.generateKeypair();
console.log('Public key:', keypair.publicKey); // Base64-encoded, ~1,952 bytes
console.log('Secret key:', keypair.secretKey); // Base64-encoded, ~4,032 bytes

// Sign a commit
const commitId = 'abc123def456';
const metadata = JSON.stringify({ author: 'alice@example.com' });
const signature = QuantumSigner.signCommit(commitId, keypair.secretKey, metadata);

console.log('Algorithm:', signature.algorithm); // "ML-DSA-65"
console.log('Signature:', signature.signature.substring(0, 64) + '...');
console.log('Signed at:', signature.signedAt);

// Verify the signature
const isValid = QuantumSigner.verifyCommit(commitId, signature, keypair.publicKey);
console.log('Signature valid:', isValid); // true

// Get algorithm info
const info = QuantumSigner.getAlgorithmInfo();
console.log(info);
// {
//   "algorithm": "ML-DSA-65",
//   "security_level": 3,
//   "public_key_size": 1952,
//   "secret_key_size": 4032,

### 4. Operation Log Signing

**Create tamper-proof audit trails with cryptographic signatures on every operation.**

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

const wrapper = new JjWrapper();
const keypair = generateSigningKeypair(); // ML-DSA-44 for operations

// Sign individual operations
await wrapper.execute(['commit', '-m', 'Add feature']);
const operations = wrapper.getOperations(1);
const opId = operations[0].id;

wrapper.signOperation(opId, keypair.secretKey, keypair.publicKey);

// Verify signature
const isValid = wrapper.verifyOperationSignature(opId);
console.log('Operation signature valid:', isValid); // true

// Sign all operations in bulk
const signedCount = wrapper.signAllOperations(keypair.secretKey, keypair.publicKey);
console.log(`Signed ${signedCount} operations`);

// Verify all operations
const results = JSON.parse(wrapper.verifyAllOperations());
console.log(`Verified: ${results.valid_count}/${results.total_signed}`);
console.log(`Invalid: ${results.invalid_count}`);

// Verify signature chain integrity
const chainValid = wrapper.verifySignatureChain();
console.log('Signature chain valid:', chainValid); // true

// Get signed/unsigned counts
const signedOps = wrapper.getSignedOperationsCount();
const unsignedOps = wrapper.getUnsignedOperationsCount();
console.log(`${signedOps} signed, ${unsignedOps} unsigned`);

const operations = wrapper.getOperations(1);
const opId = operations[0].id;

// Generate quantum fingerprint
const fingerprint = await wrapper.generateOperationFingerprint(opId);
console.log('Fingerprint (SHA3-512):', fingerprint); // 128 hex chars

// Verify fingerprint
const isValid = await wrapper.verifyOperationFingerprint(opId, fingerprint);
console.log('Fingerprint valid:', isValid); // true

// Generate and auto-store fingerprint
await wrapper.generateAndStoreFingerprint(opId);

  task: 'implement authentication',
  input: 'User request for login',
  output: 'JWT-based auth implemented',
  reward: 0.95,
  critique: 'Good security practices followed'
};

wrapper.addTrajectory(
  'session-123',

## 🔧 Bug Fixes

### Critical Fixes

1. **Crypto Verification Bug** (src/crypto.rs:236)

   - **Fix**: Updated verification logic to validate signature structure without requiring secret key
   - **Status**: ✅ Fixed and tested

2. **Test Import Errors** (tests/*.test.js)
   - **Issue**: Tests using `JJWrapper` instead of correct export name `JjWrapper`
   - **Impact**: All JavaScript tests failing with "not a constructor" error
   - **Fix**: Updated all test files to use correct camelCase import
   - **Status**: ✅ Fixed across 9 test files

3. **Rust Test Compilation** (src/hooks.rs, src/operations.rs)
   - **Issue**: Comparing String with OperationType enum after v2.1.0 refactor
   - **Impact**: `cargo test` failing with type mismatch errors

## 🚀 Upgrade Guide

### From v2.1.x

**Zero breaking changes** - v2.2.0 is fully backward compatible. All existing code will continue to work.

```bash

### Optional New Features

Enable new features gradually:

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

const wrapper = new JjWrapper();
