Role inheritance from permission not working?

Question

Yii

RBAC inherited role from permission, assign this role to user, check if he can do "permission" - false response:

role: admin
permission: canAdmin

auth_item_child:

parent         |  child
--------------+--------
canAdmin    |  admin

auth assignment:

item_name  | user_id 
--------------+-----------
admin          | 1

when checking: UPD: Through fraud, I realized that it is necessary to inherit not the role from the permission (which is logical), but the permission from the role (which is not at all logical) Why is that? After all, usually inheriting - we get the parent's saints, but here it turns out somehow the other way around
\Yii::$app->user->can('canAdmin'); // false

It's the other way around for you. In real life, a role combines powers. You even yourself first role, then permission.

role: admin
permission: canAdmin

And in the table do the opposite.
The director can have access to the admin panel, but the client does not. The admin can manage the content, but the user can't. If this is flipped, then the permission to manage content is obtained can have access to the admin . Where is the logic here?
A role is a group of permissions.
You can assign permissions directly to the user, or combine them into a group and assign a group (role) to the user. No other way. I hope it's clear.
