saihm-langgraph

saihm-langgraph has moved. It is now the LangGraph adapter inside the consolidated saihm-adapters package — the same BaseStore that gives a LangGraph app long-term memory the user owns: portable across models and frameworks, sealed client-side (Python never holds a key), and provably erasable (GDPR Art. 17).

Installing saihm-langgraph now pulls saihm-adapters[langgraph]. This package ships no code of its own.

Migration — one line

The import root changed from saihm_memory to saihm_adapters:

from saihm_adapters import SaihmStore          # was: from saihm_memory import SaihmStore

SaihmMemoryClient, Memory, and SaihmTimeout now also come from saihm_adapters:

from saihm_adapters import SaihmMemoryClient, Memory, SaihmTimeout

This is a clean break: after upgrading, import saihm_memory will fail with ModuleNotFoundError. That is intentional — the old import root is gone rather than silently shadowed, so the one change to make is obvious.

Install

pip install saihm-langgraph        # -> installs saihm-adapters[langgraph]; also needs Node.js >= 20 on PATH

or depend on the consolidated package directly:

pip install "saihm-adapters[langgraph]"

SaihmStore remains a drop-in langgraph.store.base.BaseStore — get / put / search / delete / list_namespaces, sync and async. Everything else about the adapter is unchanged; only the package that carries it and its import root have consolidated.
