+"""Unit tests for TraceQueueManager telemetry guard.
+
+This test suite verifies that TraceQueueManager correctly drops trace tasks
+when telemetry is disabled, proving Bug 1 from code review is a false positive.
+
+The guard logic moved from persistence.py to TraceQueueManager.add_trace_task()
+at line 1282 of ops_trace_manager.py:
+    if self._enterprise_telemetry_enabled or self.trace_instance:
+        trace_task.app_id = self.app_id
+        trace_manager_queue.put(trace_task)
+
+Tasks are only enqueued if EITHER:
+- Enterprise telemetry is enabled (_enterprise_telemetry_enabled=True), OR
+- A third-party trace instance (Langfuse, etc.) is configured
+
+When BOTH are false, tasks are silently dropped (correct behavior).
