Query for hierarchical RBAC scenario

Question

I have a SQLite database with a hierarchical role-based access control (RBAC) data model.

In this model, users are granted permissions to perform certain actions against various resources either directly or by being a member of one or more roles to which the permissions are assigned. Additionally roles can be assigned to other roles such that a hierarchy of roles can be defined.

The schema is roughly like the following:

(from How to design a hierarchical role based access control system - StackOverflow)

With the exception that there is a Role_Role join table instead of a "parent" column on the Roles table, similar to the below:

(from same post as above image)

Also there is no "grant" column on the join tables; existence of a record in a join table means it is granted.

What would a query to get all of the permissions for a given user look like? I'm assuming using a recursive CTE would be involved, but I'm not sure.

Edit: I've got the following recursive CTE working for getting the roles inherited by other roles:

WITH RECURSIVE
  deep_roles(role_id, parent_id, depth) AS (
    SELECT role_id, parent_id, 1 FROM role_roles WHERE role_id = ?
    UNION ALL
    SELECT rr.role_id, rr.parent_id, dr.depth+1
      FROM deep_roles dr, role_roles AS rr
     WHERE rr.role_id=dr.parent_id
       AND dr.depth < 10
  )
SELECT DISTINCT role_id, parent_id FROM deep_roles;

Not sure if this is the only CTE I'll need but it's a start.
