 1// Package logic is version 1 of the logic realm of the "state realm + swappable
 2// logic" upgrade pattern (pattern C of the exploration; see ../../README.md).

 4// Same shape as v0, different rule. The counter it reads and writes is the same
 5// one v0 was using: the upgrade changed the code without touching the data.
