langgraph-checkpoint-inspeximus

A LangGraph checkpointer backed by inspeximus.

pip install langgraph-checkpoint-inspeximus

from langgraph.checkpoint.inspeximus import InspeximusSaver

graph = builder.compile(checkpointer=InspeximusSaver(path="threads.jsonl"))

Passes LangGraph's own conformance suite (langgraph-checkpoint-conformance) at FULL 5/5 on the base capabilities — put, put_writes, get_tuple, list, delete_thread — and the suite runs in CI on every push, so the claim is checkable rather than asserted.

What it adds over a plain checkpointer: the store underneath keeps superseded values on a bi-temporal ledger, so a thread's state has queryable history and erasure leaves a signed receipt. Nothing calls a model on the write path.
