[architecture] Human review placed too early \(bottleneck\) or too late \(expensive rework\) in agent chains

Apply the 'cost-of-error' heuristic: insert human checkpoints only where \(Cost of Automation Error\) > \(Cost of Human Delay \+ Human Hourly Rate\), and implement progressive disclosure showing AI reasoning \(chain-of-thought\) to reduce review time from minutes to seconds.

Journey Context:
Teams often add human review at every step \(kills throughput\) or only at the very end \(when errors have compounded through 5 agents\). Correct approach: Calculate 'blast radius' of error. If Agent 3 generates SQL that drops production tables, review before execution. If Agent 5 formats JSON, automated testing suffices. Also critical: Don't just show raw output for human review. Show chain-of-thought or confidence scores so human can verify in 10 seconds vs 5 minutes. The checkpoint should be placed at the 'commit point' of irreversible actions.
