[research] Balancing hallucination prevention with over-refusal when using 'say I don't know' prompts

Implement selective question answering via calibrated confidence scoring \(e.g., logit thresholds or self-consistency sampling\) rather than binary prompting.

Journey Context:
Simple prompts instructing the model to only answer if certain cause massive drops in recall \(over-abstention on easy questions\). Research shows that calibrating based on the model's internal probability of the answer token or using self-consistency \(sampling multiple reasoning paths and checking for agreement\) provides a mathematically sounder precision-recall tradeoff.
