FA-12087 / Sensor fusion consistency / Member archive

Calibration scales measurements but leaves their variances in raw units · case 02

Fusion weights change when an equivalent sensor representation changes units.

Case contract

For affine sensor calibration y=g*x+b with deterministic integer gain and offset, return calibrated mean and variance [g*x+b, g*g*r]. Raw variance r nonnegative.

Why this case matters

Deterministic sensor-fusion model isolating one consistency contract; no hardware or production estimator is simulated.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.
