Case contract

Two-axis scalar-gain model: return each prior component averaged with the corresponding observation if it is not None; otherwise retain prior. Return fraction strings.

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.

Boundary fixture	Actual	Expected	Outcome
missing y	`["4", "2"]`	`["4", "4"]`	Failed
