[research] Model states answers as facts even when it should be uncertain

Elicit verbalized uncertainty and a calibrated confidence score \('high confidence / uncertain / guessing'\). Set an abstention threshold; when confidence is below it, refuse to answer or retrieve more evidence. Do not ask the model to sound confident; ask it to be calibrated.

Journey Context:
Lin et al. showed models can be taught to express uncertainty in words and that these verbalized probabilities can be calibrated; Kadavath et al. showed models mostly know what they know. The mistake is treating all outputs as equally reliable. The fix is to make uncertainty explicit and use it to route to retrieval or abstention, which is cheaper than cleaning up a wrong answer later.
