Report #75699

[architecture] Agents confidently hallucinate and pass bad data down the chain without pausing

Require agents to output a structured confidence score \(0.0-1.0\) alongside their primary payload. Configure the orchestrator with a threshold \(e.g., <0.7\) that triggers a human-in-the-loop checkpoint or fallback agent.

Journey Context:
LLMs are bad at absolute accuracy self-evaluation, but decent at evaluating ambiguity based on provided context. A binary pass/fail doesn't work because agents will default to 'pass'. By forcing a numeric score and a hard architectural threshold, you convert silent failures into explicit routing decisions. If the score field is missing, default to 0 to force escalation.
