# Engineering model calibration
# Scope: Two-point affine calibration fit; exact points, no least-squares residual model.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

xA = 1
xB = 3
yA = 2 V
yB = 6 V
query = 2

slope := (yB-yA)/(xB-xA) [V]
offset := yA-slope*xA [V]
prediction := slope*query+offset [V]

check prediction budget: prediction <= 5 V

scenario alternative: xA = 0.8
