A till is short. Someone finds a set of sales that adds up to the missing amount. Someone gets blamed.

Cuadre asks the other question: how many sets add up to it. On the shift bundled here the answer has twenty-two digits — so the set that was found proves nothing about the person who was standing there.

A match found by looking is only evidence if the looking could have failed. Every number below is exact integer arithmetic — no model, no estimate, no sampling. The count is a bigint because on a real shift it does not fit in a double.

Scenarios:

The data below is generated — register positions, never names. The amounts are shaped like Chilean retail prices because that density is the mechanism, not the decoration.
