Designed for the :query hook in Attached.Originals.list/1 and Attached.Originals.count/1:
Attached.Originals.list(
query: &Attached.Originals.Scopes.orphans(&1, "users", "avatar_attached_original_id")

Restricts a query to orphaned originals within a single (owner_table, owner_field) group.
Functions
Restricts a query to originals belonging to a specific (owner_table, owner_field) group.
Restricts a query to orphaned originals within a single (owner_table, owner_field) group.
An original is orphaned when no row in owner_table references it via the
owner_field column. The group is required because SQL identifiers
(table/column names) can't be bound per row — iterate
Attached.Originals.list_owner_groups/0 to cover every group.
