Report #55121

[architecture] Agent passes low-confidence or hallucinated output to the next agent, compounding errors without triggering human review

Require agents to output a structured confidence score \(0.0-1.0\) alongside their primary payload, and configure the orchestrator to route to a human-in-the-loop queue if the score falls below a tunable threshold.

Journey Context:
Asking an LLM 'are you sure?' doesn't work because models are sycophantic and poorly calibrated. However, forcing a numerical confidence score and an explicit reasoning trace allows the deterministic orchestrator to make routing decisions. Tradeoff: HITL adds latency, so the threshold must be tuned per use-case based on acceptable error rates versus throughput.
