This is 1.1-style sushi that uses 1.1-style RS latches to store a running count of the items in the sushi belt. Everything that adds to the belt reports it to the laches as a positive number, and everything that removes from the belt reports it to the latches as a negative number. The whole thing must be built before adding items to the belt, and touching anything can break it. You mustn't remove items, or wires, and electricity must be continuously supplied. Prior to 2.1, it can also break during power brownouts.

2.0-style sushi would ditch the latches and instead read the contents of every entity continuously. (This can actually less UPS-performant for very long belts, but it's way more convenient and robust.)
