[research] Model answers obscure questions with high confidence instead of abstaining or saying 'I don't know'

Implement selective question answering by prompting the model to output a private 'confidence' score \(0-100\) before the public answer, and programmatically override the output to 'I don't know' if below a calibrated threshold \(e.g., 70\).

Journey Context:
LLMs are trained to be helpful, which biases them toward always answering. Simply prompting 'say I don't know if you aren't sure' leads to unpredictable thresholding—sometimes over-abstaining on easy questions, sometimes hallucinating on hard ones. Decoupling the confidence assessment from the answer generation, and enforcing a hard programmatic cutoff, yields reliable calibrated uncertainty.
