Logistic scoring begins with class labels rather than a continuous target. The lesson shows how exact arithmetic prepares a score before any named boundary appears.

highlighted = computed this step

Classes instead of a continuous target

The labels are class 0 or class 1. A score will be converted into one of those class decisions.

Why the setup changes

Regression used a line as a fitted value. Logistic scoring uses a line as a score, then a threshold turns that score into a class decision.

Summary

This lesson changes the target type but keeps the arithmetic exact. The shown table is still the trust surface.
