Report #53616

[architecture] Human review is placed at the end of the agent chain, catching failures too late when cost and side effects have already accumulated

Insert human checkpoints before irreversible actions \(writes, sends, deployments\) and after high-uncertainty steps \(ambiguous user intent, low-confidence classification\), not just at the end of the pipeline.

Journey Context:
The default pattern is to let the agent chain run to completion and then have a human review the final output. This is wrong for two reasons: \(1\) if an early agent misinterpreted intent, all downstream work is wasted, \(2\) if intermediate agents took irreversible actions, the human cannot undo them. The correct pattern is risk-based checkpoint placement: before any write operation, after any intent classification, and at trust boundaries \(e.g., when passing from a 'research' agent to an 'execution' agent\). The tradeoff is that more checkpoints mean more latency and human fatigue — alert fatigue leads to rubber-stamping — so you must be selective. The heuristic: checkpoint at state transitions, not at every step.
