    2. Find statistics on European auto imports via the canal
    3. Locate financial reports from major manufacturers during that period

    2. Corrective RAG (CRAG) Self-Grading

    The system evaluates retrieved content quality in three categories:

    • Correct: Relevant, sufficient context – proceeds to generation
    • Ambiguous: Potentially relevant but unclear – triggers query refinement
    • Incorrect: Irrelevant content – initiates fallback to external search

    3. Hybrid Retrieval & Local Reranking

    The pipeline combines the strengths of different search methods:

    • Dense Retrieval: Semantic vector search using ChromaDB
    • Sparse Retrieval: Keyword matching via BM25

    2. System analyzes query complexity and decomposes if needed
    3. Parallel retrieval from ChromaDB (vector) and BM25 (keyword)
    4. Self-grading evaluates retrieved chunks quality
    5. Ambiguous/incorrect results trigger refinement or external search
    6. Merged results are reranked by local Jina model
    7. Final context sent to Qwen 30B for answer generation
    8. Response and provenance returned via streaming WebSocket

    Comparison: CRAG MultiHop vs Traditional RAG

    Feature Traditional RAG CRAG MultiHop
    Query Complexity Single-step Multi-hop (up to 3 steps)
    Retrieval Quality No self-assessment Self-grading with fallbacks
    Search Method Single mode (usually vector) Hybrid vector + keyword
    Transparency Black box Real-time pipeline monitoring
