+    **Streaming Syndrome Interface**
+    
+    For real-time applications, the decoder provides an ``enqueue_syndrome()``
+    method that accepts syndrome data one round at a time. This allows the host
+    to feed syndrome measurements as they arrive without waiting for all rounds
+    to complete. The decoder automatically manages internal buffering and triggers
+    window decodes at appropriate boundaries.
