  [inst : CategoryTheory.Category.{v, u} C] → CategoryTheory.MorphismProperty C → CategoryTheory.Precoverage C → Prop

A property of morphisms P in C is local at the source with respect to the precoverage K if it respects isomorphisms, and: P holds for f : X ⟶ Y if and only if it holds for the restrictions of f to Uᵢ for a 0-hypercover {Uᵢ} of X in the precoverage K.
