Report #51889

[architecture] Silent error cascades when downstream agents treat low-confidence upstream outputs as ground truth

Propagate uncertainty metadata \(confidence scores, entropy, or token logprobs\) through the chain with adaptive circuit-breakers that trigger human escalation when aggregate confidence falls below dynamic thresholds

Journey Context:
Standard approaches add a confidence check at the end, but errors compound multiplicatively. If Agent A is 60% confident and Agent B processes that as fact with 60% confidence, the final output may be 36% reliable but treated as high confidence. You need to propagate uncertainty quantification \(UQ\) through the pipeline with circuit-breaker logic per Martin Fowler, but adapted for agent chains: if the product of confidences < threshold, stop and escalate.
