Use human_review for a general checkpoint. Approval-gated and manual tools populate run.pause.pending_tool_calls with exact call IDs. Continue through Agent#continue_run with:
  • ToolDecision values in approvals or rejections
  • ToolOutput values for manual work
  • human_input for a general review pause
  • the prior run, or run_id with a state accessor
Decisions use exact call IDs, so concurrent calls to the same tool remain distinct. A compatible state object implements load(run_id) and save(result).
