Module spec 

A curve recipe stated as data.

A RecipeSpec is what a recipe source — a desk’s configuration, a connector — hands over in place of builder calls. It is converted by applying the same builder operations in the same order hand-built code applies, so a spec is refused exactly where the builder chain would be, and a recipe converted to a spec and back is the recipe it came from.
