[architecture] Cascading hallucinations compound errors when low-confidence agent outputs pass unchecked

Require agents to emit a structured confidence score \(0.0-1.0\) alongside their primary output. Configure the orchestrator with a threshold: if confidence is below the threshold, route to a human-in-the-loop \(HITL\) queue or a verification agent rather than the next execution agent.

Journey Context:
Agents naturally hallucinate. In a pipeline, a small hallucination in step 1 becomes a foundational premise for step 2. LLMs are bad at self-evaluating confidence natively, so you must force it via structured output. The tradeoff is that forced confidence scores can themselves be hallucinated, so combining this with deterministic validation is necessary. HITL adds latency but prevents catastrophic compounding errors.
