## 12. Future Enhancements

1. **Directory Leases**: Extend lease support for directories
2. **Lease Key Persistence**: Save lease keys for reconnection
3. **Parent-Child Relationships**: Implement hierarchical leases
4. **Lease Sharing**: Support lease sharing across handles

                    LeaseEntry lease = entry.getValue();
                    log.info("Evicting lease for path: {} due to max lease limit", lease.getPath());

                    // Flush any cached data before eviction
                    if (lease.hasWriteCache()) {
                        flushCachedWrites(lease.getPath());
                    }
                    if (lease.hasReadCache()) {

/**
 * SMB2 Lease Key
 *
 * Represents a 16-byte lease key used to identify leases in SMB2/SMB3
 * MS-SMB2 2.2.13.2.8
 */

- [ ] Modify SmbFile to support lease-based caching
- [ ] Add lease upgrade/downgrade logic
- [ ] Implement lease epoch tracking for v2 leases

#### 1.3 Integration Points
- Modify `Smb2CreateRequest` to include lease contexts
- Update `SmbFile` caching logic to use leases
- Add lease break handling in `SmbTransport`
