1"""Concept graph for LazyGraphRAG-style index-time knowledge extraction. 

2 

3Extracts noun-phrase concepts from chunks via spaCy, builds a PPMI-weighted 

4co-occurrence graph (Church & Hanks 1990), and clusters with Leiden 

5(Traag et al. 2019, graspologic-native). Used to boost search results by 

6concept overlap and expand queries via graph traversal. 

7 

8Requires optional ``graph`` extra: ``pip install lilbee[graph]``. 

9When dependencies are missing, all public functions degrade gracefully.
