📄 Description

Summary

  • Add a Warning callout to the Graph API docs explaining that private state channels are not redacted during streaming.
  • Document that stream_mode="values" / streamMode: "values" defaults to the full set of state channels rather than the output schema, so private channels (e.g. bar) are visible while streaming even though invoke hides them.
  • Show how to restrict streamed values via output_keys (Python) / outputKeys (JS), and note stream_mode="updates" as an alternative for per-node output.
  • Mirror the guidance across both the Python and JS tabs.
