I think that for the complexity of what you're doing with auth, then the 
authorization should be in the model layer.

You should have methods on the model layer which take some form of 
'user', and restrict what can be retrieved by that user. This is domain 
logic, so you need to build it into the domain.

DBIx::Class::Schema::RestrictWithObject is probably the place to start 
looking.
