[architecture] Overconfident low-quality outputs poisoning downstream reasoning

Implement calibrated confidence scoring with hard escalation triggers: use logprobs or self-consistency voting to score confidence; define DAG-specific thresholds \(e.g., <0.7 confidence → human-in-the-loop checkpoint\); never allow uncertain intermediate data to reach aggregation agents without explicit uncertainty flags.

Journey Context:
LLMs are overconfident; raw logprobs are miscalibrated. Without confidence gates, uncertain parsing results \(e.g., extracted dates with 0.4 confidence\) flow into SQL generators, creating garbage queries. Hard stops prevent this. Thresholds must vary by agent type—parsers need strict gates, creative writers need looser ones. Bayesian calibration \(Platt scaling\) helps. Alternative: uniform thresholds across pipeline—too rigid for mixed agent types.
