+> [!failure]
+> Several fixtures were erroneously based on NM cable.
+

+to be an unswitched hot.
+Joel is having me change them to \#12/2.
+
+#### Units

+
+Suppose a true cost model,
+accounting for all relevant information available at time $t$.
+
+$C(t)$ returns a distribution whose [scale](https://en.wikipedia.org/wiki/Scale_parameter)
+decreases with $t$, and $C(0)$ maps to a single value.
+$t>0$ is time until the final payment.
