[research] LLM expressing high confidence in incorrect code or factual statements without hedging or saying 'I don't know'

Implement calibrated uncertainty via self-consistency checks \(sampling N times and checking for variance\) and instruct the model to explicitly state 'I don't know' when code outputs diverge across samples.

Journey Context:
Standard prompting encourages definitive answers. Logprob calibration shows that high probability does not equal high factual accuracy \(the calibration gap\). Self-consistency provides a better proxy for confidence: if the model generates 10 different solutions, it doesn't 'know' the answer.
