[FEATURE] Support CK permission control

### Describe the feature

Our company needs to manage CK permission control.

Perhaps I might go and implement it.

I open an issue first.

### Motivation

_No response_

### Describe the solution

_No response_

### Additional context

_No response_

The issue does not name any files, tests, entry points, or concrete permission-control requirements. First clarify what “CK” refers to and the intended permission model; done should be defined by an agreed solution and corresponding validation criteria.
