How to detect:

`autogroup:self` only applies to user-owned devices and cannot be used with `autogroup:tagged`. Attempting to use both in the same policy will result in incorrect access control behavior or policy validation failures.

Recommended action:

Review ACL rules that reference `autogroup:self` and ensure they do not also reference `autogroup:tagged`. Separate rules for user-owned devices and tagged devices. For tagged devices, use explicit tag references instead of `autogroup:self`.
