"""
Knowledge Extraction Evaluations

Tests the quality of knowledge extraction from conversation summaries.
Ensures the extraction prompt correctly handles:
1. Assistant self-references (should NOT be extracted)
2. Stale temporal snapshots (should NOT be extracted)
3. Common knowledge (should NOT be extracted)
4. Novel knowledge (SHOULD be extracted)
5. Proper reframing (requests → knowledge, not interaction descriptions)

Run:
