Test: Checking conv1_classification.json...
ERROR: need_reply should be true for conv1, got: False
Reason given: The most recent message is from contact 15 (Michał Flak) stating they tried something and it didn't work. While the user (Mathieu, contact 4) was mentioned earlier in the thread and participated in the conversation, the last message doesn't appear to be directed at or waiting for the user specifically. The conversation seems to have concluded with Michał's update about trying Lovable.
