[research] Confidently answering obscure or out-of-distribution questions

Implement semantic entropy checks or logit-based confidence thresholds. If entropy across multiple generations is high, force the output to 'I don't know' or trigger a retrieval action.

Journey Context:
LLMs inherently lack a calibrated sense of their own knowledge boundaries. Standard prompting to 'say I don't know' often fails because the model's internal confidence is miscalibrated. Using token probabilities or measuring semantic consistency across multiple generations provides a mathematically grounded signal for abstention, trading recall for precision.
