[architecture] Agents hallucinate high confidence on ambiguous tasks instead of escalating to humans

Implement a dual-metric confidence scoring system: an LLM-self-assessed score AND a deterministic heuristic score \(e.g., vector distance to known-good examples\). If either falls below a threshold, trigger a human-in-the-loop checkpoint before proceeding.

Journey Context:
LLMs are notoriously bad at self-assessing confidence, often reporting 90%\+ confidence on hallucinated answers. Relying solely on the LLM's self-reported confidence for HITL escalation results in missed interventions. By combining self-assessment with a deterministic metric \(like cosine similarity of the generated plan to a corpus of verified plans\), you trade a small amount of false-positive escalations for a massive reduction in catastrophic autonomous failures.
