Test: Checking conv3_classification.json...
ERROR: need_reply should be true for conv3, got: False
Reason given: The user (Mathieu, contact_id 4) sent the last substantive message providing the eval website URL to Nik. The subsequent messages from contact_id 70 (Nik) are follow-up questions about how to use the eval system, but they are not directed specifically at Mathieu - they are general questions that could be answered by anyone. No direct response is expected from the user at this point.
