Start with tests/sentry/feedback/lib/test_label_query.py, especially TestLabelQuery::test_query_recent_feedbacks_with_ai_labels around line 150, and run the named test to reproduce the empty result. Review the linked GitHub Actions run for context. Done means the test passes reliably without intermittent IndexError failures.
