How a grant reaches the queried space, i.e. where its space sits relative to it.
- RESIDENTThe grant lives on the queried space itself.
- PROPAGATEDThe grant lives on an ancestor space and reaches the queried space by propagating down.
- INHERITEDThe grant lives on a descendant space and reaches the queried space by inheritance up the tree (the descendant chain has inherit_entities enabled).
