[research] Using vague hedging language instead of calibrated confidence scores or explicit 'I don't know' boundaries

Enforce a strict structured output format for confidence \(e.g., High/Medium/Low\) or extract logprobs. If confidence is below a threshold, force the model to output a standardized 'I don't know' block rather than guessing with hedging words.

Journey Context:
LLMs are notoriously poorly calibrated; their verbalized 'confidence' does not correlate well with actual correctness. Verbal hedges \('It seems like', 'Usually'\) provide zero actionable signal for automated agents. By forcing discrete confidence buckets or utilizing token logprobs, an agentic pipeline can programmatically route low-confidence outputs to a human or a different tool, rather than proceeding with a likely hallucination.
