  • All code examples have been tested and work correctly
  • I have used root relative paths for internal links

  • Not required — individual provider/retriever pages are auto-discovered and do not need a docs.json entry

Additional notes

Adds documentation for langchain-engram, a LangChain integration for Engram — cognitive memory infrastructure for AI agents.

Engram differs from simple vector stores by tracking calibrated confidence scores, detecting contradictions between beliefs, and managing memory lifecycle (decay, consolidation, tier promotion).

This PR adds one integration:

  • EngramRetriever — BaseRetriever backed by Engram's hybrid vector + knowledge-graph recall, returning Document objects with confidence score, memory tier, and relevance metadata.

Package published at pip install langchain-engram. Tested against langchain-core 0.3.x and 1.x.
