 Agent Framework provides comprehensive checkpointing through `FileCheckpointStorage` and the `with_checkpointing()` method on `WorkflowBuilder`. Checkpoints capture:
 
-- **Executor state**: Local state for each executor using `ctx.set_state()`
+- **Executor state**: Local state for each executor using `ctx.set_executor_state()`
 - **Shared state**: Cross-executor state using `ctx.set_shared_state()`
 - **Message queues**: Pending messages between executors
 - **Workflow position**: Current execution progress and next steps
