[architecture] Overconfident agent outputs cascading errors through downstream automation

Implement statistical process control \(SPC\) by requiring each agent to output a calibrated confidence score \(e.g., log-probability or temperature-scaled entropy\); downstream router agents apply Western Electric rules—if confidence falls outside 3-sigma control limits or exhibits runs \(7 consecutive points above/below mean\), trigger a circuit breaker to halt the chain and escalate to human review.

Journey Context:
Raw LLM probabilities are poorly calibrated \(overconfident on hallucinations\), so naive thresholding fails. However, relative confidence drops or entropy spikes are statistically significant signals. Common mistakes include: \(1\) using raw softmax probabilities without temperature scaling, \(2\) setting static thresholds per agent rather than dynamic baselines, \(3\) failing to account for drift in agent behavior over time. The SPC approach treats agent outputs as a manufacturing process—analogous to semiconductor yield monitoring—where deviation from historical baselines indicates special cause variation requiring intervention, not just common noise.
