Let be any smooth free scalar, . Define

by the switched scalar equation and zero positive-order Cauchy data. For the metric jet,

Hence

The sources are smooth and compactly supported because their coefficients contain or its derivatives.

Evaluation of the relational functional on this scalar solution gives

Square brackets distinguish evaluated solution coefficients from the bare coefficients (eq:Ozero)–(eq:Otwo).
