Confidence-banded predictions
The number is the headline. The band is the methodology.
Every prediction comes with a 90% confidence interval — derived from quantile regression against the comparable cohort, not bolted on. The band widens when the cohort is thin or the severity is catastrophic. It's the part of the output that survives the carrier's "where did you get this number?" — and the part that tells you when to slow down before signing the retainer.
9 of 10 cases with the same input profile settle inside the published range. The other 10% are the long tail — flagged, not hidden.
