[architecture] Miscalibrated confidence scores cause wrong automated decisions or alert fatigue

Calibrate confidence scores using Platt scaling or isotonic regression on a held-out validation set, then apply cost-sensitive thresholds: compute the expected loss of false positives vs false negatives for your specific domain, and set dynamic thresholds that optimize for the business cost rather than raw accuracy.

Journey Context:
Raw softmax probabilities from LLMs or classifiers are poorly calibrated \(often overconfident\). Agents making routing decisions based on uncalibrated '0.9 confidence' thresholds will either escalate too much \(alert fatigue\) or miss critical errors. Proper calibration maps model outputs to true probabilities \(e.g., 80% of instances with 0.8 confidence should be correct\). Combining this with cost-sensitive thresholds \(where false negatives in medical diagnosis cost 100x more than false positives\) creates robust escalation logic that minimizes expected economic loss rather than just error rate.
