Three earth and one water loads anime and the salt in tissue comes from water.

The decision of arm one moving atoms for top and bottom row gives close to enough constraints to anchor the solve in place. There are then how to distribute calcification, where do the two bars meet, and how many arms can fit into the earth-anime loop (one of two mors arms can so technically there's an 0g/-2i improvement there). Then a bunch of swinging arms around for potential track rivering opportunities.
