Test: Checking conv1_classification.json...
SUCCESS: conv1 correctly classified as not needing reply
Reason: User ID 4 (Mathieu) is mentioned directly in messages 00012 and 00111, and the last message from sender 15 (message 00011) mentions user ID 4 via 'cc @**Mathieu**' (message 00202) and quotes a message from user ID 4 (message 00011). This indicates an active exchange or a direct notification to the user.
conv1 classification test passed!
