# 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();
  }
