-Prevents concurrent execution while allowing new instances to queue.
+`ShouldBeUnique` holds the lock until the job completes. `ShouldBeUniqueUntilProcessing` releases it when processing starts, allowing new instances to queue.
 
 ```php
-public function middleware(): array
+class UpdateSearchIndex implements ShouldQueue, ShouldBeUniqueUntilProcessing
 {
-    return [new WithoutOverlapping($this->product->id)->untilProcessing()];
+    // Lock releases when processing begins, not when it finishes
 }
 ```
 
-Without `untilProcessing()`, the lock extends through queue wait time. With it, the lock releases when processing starts.

 ## Use Horizon for Complex Queue Scenarios
 
 Use Laravel Horizon when you need monitoring, auto-scaling, failure tracking, or multiple queues with different priorities.
