Report #72145

[architecture] Overconfident agent outputs propagate errors through chains

Replace softmax probabilities with calibrated confidence intervals using temperature scaling or MC dropout; implement hard thresholds \(e.g., entropy > 2 bits or confidence < 0.9\) that trigger automatic human handoff before downstream consumption.

Journey Context:
Raw LLM probabilities are miscalibrated—high softmax values don't correlate with actual accuracy. Static thresholds fail under distribution shift. Alternative: ensemble disagreement. Tradeoff: calibration requires a held-out validation set and adds inference cost \(MC dropout requires multiple forward passes\), but prevents silent compounding of errors in multi-agent chains where one agent's fiction becomes another's fact.
