Report #90737

[architecture] Human reviewers become bottlenecks and single points of failure when asked to verify every low-confidence agent output, or conversely, high-stakes decisions are auto-approved without oversight

Implement tiered confidence thresholds with dynamic sampling: high-confidence \(>0.9\) auto-approve, medium \(0.7-0.9\) use differential privacy budgets \(epsilon\) to sample for human review, low \(<0.7\) require human review; use active learning to prioritize uncertain samples and retire reviewed samples to a feedback buffer for model fine-tuning

Journey Context:
Static thresholds \('if confidence < 0.8, escalate'\) break down because confidence calibration varies by task and model. In high-volume systems, requiring human review for everything above a threshold creates a queue that grows without bound \(the 'human bottleneck'\). Conversely, auto-approving everything below a threshold risks catastrophic errors. The solution is dynamic, context-aware sampling inspired by differential privacy budgets. You allocate a daily 'human attention budget' of N reviews \(the epsilon budget\). High-confidence outputs \(>0.9\) are auto-approved. Low-confidence \(<0.7\) always consume budget \(mandatory review\). For medium confidence, you sample probabilistically: the probability of review is \(remaining\_budget / remaining\_requests\), ensuring you never exceed the daily quota while maintaining uniform coverage of the medium-risk population. This prevents queue overflow while ensuring risky items are caught. Active learning prioritizes the most uncertain samples \(closest to 0.5 probability\) for review, maximizing information gain. Reviewed samples are fed back into a fine-tuning pipeline to improve the model and reduce future human load.
