Report #30559

[architecture] Overconfident agent outputs bypassing quality gates

Use token-level logprobs to calculate calibrated confidence scores; set explicit thresholds \(e.g., <0.85 mean token probability triggers human escalation\); never rely on semantic certainty cues like 'I think' or 'Certainly'.

Journey Context:
Raw LLM outputs have no built-in uncertainty metric. Developers rely on the model saying 'I'm not sure' which fails because models are calibrated to sound authoritative. Using token-level logprobs provides statistical confidence. However, logprobs are expensive to compute and calibrating thresholds requires held-out validation data. Alternative \(ensemble voting\) is more robust but costly.
