Report #71402

[architecture] Hallucinated or uncertain agent outputs silently cascading to downstream agents

Require agents to emit a structured confidence score or explicit uncertainty tokens alongside their primary output. Configure the orchestrator to route low-confidence outputs to a fallback agent or human-in-the-loop rather than the next logical step.

Journey Context:
Downstream agents often assume upstream outputs are factual. If Agent A hallucinates, Agent B will confidently reason on top of that false premise. LLMs are bad at self-evaluating, but forcing a confidence score makes uncertainty explicit. Tradeoff: LLMs often overestimate confidence; calibrating this requires few-shot examples of uncertain vs certain outputs.
