Family gravity

The contract in words, and how to choose

No hand-written part: how to choose among this family’s laws, or to attach them together, is not written yet.

Contract

What every member must satisfy, as the family’s harness checks it on the member’s own node.

• Sign rule: weight minus buoyancy lies along gravity, pointing with it when the body is heavier than the fluid it displaces

• Cases a member passes: sign, frame, units, material reach, oracle, gradients, nodes

• Settings that stand for a material’s properties, each of which must reach the output: mass, buoyant_volume, fluid_density, centre_of_buoyancy

• Deliveries a two-way law makes equal and opposite: none

• Reference member a swap replaces: none

• Settings proportional to a material property: none
