Fixes #694
Local LightRAG queries returned the synthesized answer but discarded the structured retrieval data that LightRAG already exposes through
aquery_data(). This forwards stable chunk, entity, relationship, and file-reference metadata into the existing RAG source event.The answer continues through
RAGAnything.aquery()so the current VLM-enhanced response behavior is preserved. When an older LightRAG installation lacksaquery_data()or provenance lookup fails, the answer still succeeds and DeepTutor keeps the existing query-echo fallback.Tests:
uv run pytest tests/services/rag/test_lightrag_pipeline.py -quv run pytest tests/core/test_builtin_tools.py -quv run pre-commit run --files deeptutor/services/rag/pipelines/lightrag/engine.py deeptutor/services/rag/pipelines/lightrag/pipeline.py tests/services/rag/test_lightrag_pipeline.pyAI assistance: Codex assisted with implementing and testing this focused change.
