"""Quality tests for agentic search - verify actual functionality, not just "doesn't crash".
These tests verify:
1. similarity_score > 0 for all results (embeddings work)
2. Results are relevant to query (contain query keywords)
3. Crawling stores data (chunks_stored > 0 after web_search)
4. Completeness improves after crawling new data
REQUIREMENTS:
- Qdrant running on localhost:6333
- SearXNG running on localhost:8080
- OPENAI_API_KEY set in environment
- AGENTIC_SEARCH_ENABLED=true
- NO MOCKS - all services must be real
These are NOT flaky tests - they verify deterministic properties:
- Embeddings produce non-zero similarity scores
- Search results contain query terms
- Database operations persist data
