"""
Answering module for QAFD-RAG.

This module handles the query-time operations: from user question to final answer.
It coordinates keyword extraction, entity retrieval, graph traversal, context assembly,
and response generation.

Submodules:
-----------
- handler: Main query entry point (kg_query)
- context: Context building based on query modes
- clusters: Flow diffusion cluster operations
- text_units: Text chunk retrieval

Note: Evaluation functions have been moved to src/evaluation.py
