+ # Match a read permission for the user to the record's
+ # owner_uuid. This is so we can have a permissions table that
+ # mostly consists of users and groups (projects are a type of
+ # group) and not have to compute and list user permission to
+ # every single object in the system.
+ #
+ # Don't do this for API keys (special behavior) or groups
+ # (already covered by direct_check).

+ # The traverse_owned flag indicates whether the permission to
+ # read an object also implies transitive permission to read
+ # things the object owns. The situation where this is important
+ # are determining if we can read an object owned by another
+ # user. This makes it possible to have permission to read the
+ # user record without granting permission to read things the
+ # other user owns.
