Report #41439

[architecture] Agents silently fail or hallucinate when uncertain instead of escalating to humans

Require agents to output a discrete confidence score \(e.g., 0.0-1.0\) alongside their primary payload. Define hard thresholds in the orchestrator: if confidence < 0.7, route to a verification agent; if < 0.4, pause and escalate to a human-in-the-loop \(HITL\) queue.

Journey Context:
LLMs are naturally sycophantic and overconfident; asking 'are you sure?' doesn't work. By forcing a structured confidence field and handling the routing deterministically in code \(not in the LLM\), you prevent low-confidence outputs from cascading into catastrophic failures downstream. The tradeoff is increased latency and human cost, but it guarantees an upper bound on error rates for critical paths.
