// Package role defines the permission vocabulary that authorizes console and
// management behavior.
//
// Roles are rows in the roles table and their permissions live in
// role_permissions, so a tenant can define its own and authorization is
// resolved by the database rather than from a matrix held here. What belongs in
// this package is the closed set of permissions a role may be granted, plus the
// labels the console renders.
//
// Keep the permission list in step with the role_permissions_permission_check
// constraint in migration 0006: a name that is not in both places cannot be
// stored.
