### Phase 2: Persistent Handles
**Priority: HIGH** | **Estimated Effort: 4-5 weeks**

Persistent handles allow connections to survive network interruptions and server failovers.

#### 2.1 Core Persistent Handle Infrastructure
```
Package: jcifs.internal.smb2.persistent
├── PersistentHandleContext.java     - Persistent handle create context

    /** Whether to use persistent handles for maximum reliability */
    protected boolean usePersistentHandles = false;
    /** Timeout for durable handles in milliseconds */
    protected long durableHandleTimeout = 120000; // 2 minutes
    /** Maximum number of retry attempts for handle reconnection */
    protected int handleReconnectRetries = 3;
    /** Directory to store persistent handle state */

        }

        @Test
        @DisplayName("Persistent handles capability should be 0x10")
        void testGlobalCapPersistentHandles() {
            assertEquals(0x10, Smb2Constants.SMB2_GLOBAL_CAP_PERSISTENT_HANDLES, "Persistent handles capability must be 0x10");
        }

        @Test
        @DisplayName("Directory leasing capability should be 0x20")

            attemptCount.incrementAndGet();
            throw new RuntimeException("Persistent failure");
        });

        try {
            fesenClient.get(c -> mockFuture);
            fail("Expected exception after max retries");
        } catch (RuntimeException e) {
            assertEquals("Persistent failure", e.getMessage());
        }

        // Should try initial + maxRetryCount times (1 + 3 = 4)

     */
    boolean isUseDurableHandles();

    /**
     * Property {@code jcifs.smb.client.usePersistentHandles}, defaults to false
     *
     * @return whether to use persistent handles for maximum reliability
     */
    boolean isUsePersistentHandles();

    /**
     * Property {@code jcifs.smb.client.durableHandleTimeout}, defaults to 120000
     *

**DataService**: Access result persistence, iteration

**Implementations**:
- `UrlQueueServiceImpl`, `DataServiceImpl`: In-memory (default)
- `OpenSearchDataService`: OpenSearch backend (persistent)
