Report #36279

[architecture] Agents silently proceed with low-confidence outputs, compounding errors through the pipeline

Require agents to output a confidence score \(0.0-1.0\) alongside their primary output as part of their structured schema. Define hard programmatic thresholds: if score < threshold, halt and escalate to human or a more capable model.

Journey Context:
LLMs are naturally sycophantic and overconfident; simply asking 'are you sure?' does not work. By forcing a numerical confidence score as a required schema field, you create a programmatic hook for control flow. The tradeoff is latency: human escalation kills throughput. Thresholds must be tuned per task based on error-cost analysis.
