Report #90506

[architecture] Humans are overwhelmed with review requests or critical errors slip through because HITL is only at the end of long agent chains

Place HITL checkpoints at 'irreversibility boundaries'—before actions that cannot be undone \(payments, deletions, external notifications\) and after 'uncertainty accumulation points' where multiple low-confidence agent outputs converge; implement tiered review where low-risk actions are auto-approved with audit logs, high-risk require synchronous confirmation, and critical paths require dual authorization.

Journey Context:
Putting HITL only at the start \(priming\) or end \(final review\) fails to catch compounding errors in the middle. Agents are black boxes—intermediate outputs need spot checks. The key is identifying irreversible actions vs. reversible ones \(drafts can be auto-generated, sends need approval\). The tradeoff is latency—synchronous HITL kills throughput. Solution is async review for non-blocking paths and 'shadow mode' where humans review AI decisions post-hoc to calibrate when to remove HITL. This prevents 'automation surprise' where the system acts unpredictably because no human saw the intermediate reasoning.
