Privileged issue

  • I am a LangGraph maintainer, or was asked directly by a LangGraph maintainer to create an issue here.

Issue Content

If you use a checkpointer, state vars are persisted across the same thread. Developers can mark state keys as run-scoped with UntrackedValue. This should be documented better, along with EphemeralValue
