Recommended action: Pass a checkpointer to compile() (e.g. InMemorySaver for dev, Postgres/SQLite saver for prod) or @entrypoint(checkpointer=...), and pass a thread_id in config; on LangGraph Server/API persistence is provided automatically.
Option: Compile with a checkpointer [evidence: official_recommended_action]
Applies when: LangGraph Graph/Functional API
Steps:
1. from langgraph.checkpoint.memory import InMemorySaver
2. graph = builder.compile(checkpointer=InMemorySaver())
3. graph.get_state({'configurable': {'thread_id': '1'}})
Expected: State APIs work
Evidence basis (self-declared by the contributing chat client): untested.
