[architecture] Orchestrator accepts high-confidence hallucinations without verification

Require agents to output a structured confidence score alongside their answer, and mandate deterministic verification \(e.g., code execution, fact-checking tool, or human-in-the-loop\) if the score is below a threshold OR if the task is high-stakes, regardless of the score.

Journey Context:
LLMs are notoriously miscalibrated; they frequently report high confidence on incorrect or hallucinated answers. Relying solely on the LLM's self-reported confidence as a gatekeeper is an anti-pattern. The correct architectural pattern is to use confidence as a triage mechanism: low confidence equals automatic escalation to HITL or a different agent; high confidence equals deterministic check \(if high stakes\). Tradeoff: Deterministic checks and HITL add latency and cost, but they prevent catastrophic autonomous failures in production.
