Module lance 

LanceDB graph storage for the memory hook.

Three tables: entities (typed nodes with FTS), relations (directed edges between entities), and journals (compaction summaries with vector embeddings for semantic search). Mutations use lancedb directly; graph traversal uses lance-graph Cypher queries via DirNamespace. Entities and relations are shared across all agents (DD#40). Journals are agent-scoped.
