📄 Description

Description

The LangGraph persistence docs claimed checkpointing only happens at super-step boundaries, but node-level task writes are also persisted to the checkpoint_writes table as each node finishes. Updated the Super-steps section to describe both levels and tie the per-task writes to the existing pending-writes recovery behavior.

Release Note

Clarified in the LangGraph persistence docs that checkpointing happens at both the super-step and node (task) level, with per-node writes stored in checkpoint_writes.

Test Plan

  • Verify the updated Super-steps section renders correctly in Mintlify preview

Opened collaboratively by Naomi Pentrel and open-swe.
