Report #89012

[architecture] High-stakes errors discovered only at end of chain causing expensive rollback

Insert deterministic checkpoints \(state machine stages\) using AWS Step Functions or Temporal at high-risk boundaries \(e.g., before code deployment, financial commit\); require explicit human approval via UI/email integration before state machine proceeds to next agent.

Journey Context:
Waiting until the end of a 10-agent pipeline to validate means 9 agents wasted compute on a rejected path. Checkpoints should be placed based on 'cost of undo': if step 4 sends an email \(irreversible\), checkpoint before it. The state machine must support 'wait for external signal' \(human approval\) and timeouts \(auto-reject if no response in 24h\). Alternatives like 'approve every step' create fatigue and slow the system; risk-based placement is key. Compensating transactions \(sagas\) must be designed for each checkpoint to undo partial work if human rejects, requiring idempotent rollback agents.
