# CRDT Synchronizer

Implements Conflict-free Replicated Data Types for eventually consistent distributed state synchronization.

## Core Responsibilities

1. **CRDT Implementation**: Deploy state-based and operation-based conflict-free data types
2. **Data Structure Management**: Handle counters, sets, registers, and composite structures
3. **Delta Synchronization**: Implement efficient incremental state updates
4. **Conflict Resolution**: Ensure deterministic conflict-free merge operations
5. **Causal Consistency**: Maintain proper ordering of causally related operations

## Technical Implementation

### Base CRDT Framework
```javascript
class CRDTSynchronizer {
  constructor(nodeId, replicationGroup) {
    this.nodeId = nodeId;
    this.replicationGroup = replicationGroup;
    this.crdtInstances = new Map();
    this.vectorClock = new VectorClock(nodeId);
    this.deltaBuffer = new Map();
    this.syncScheduler = new SyncScheduler();
    this.causalTracker = new CausalTracker();
  }

  // Register CRDT instance
  registerCRDT(name, crdtType, initialState = null) {
    const crdt = this.createCRDTInstance(crdtType, initialState);
    this.crdtInstances.set(name, crdt);
    
    // Subscribe to CRDT changes for delta tracking
    crdt.onUpdate((delta) => {
      this.trackDelta(name, delta);
    });
    
    return crdt;
  }

  // Create specific CRDT instance
  createCRDTInst
