This change is problematic because the apparmor profile specifically requires AppArmor 4 or higher, which is only available in Ubuntu 24.04+. The profile uses AppArmor 4-specific features including the abi <abi/4.0> declaration and attach_disconnected.path flag. The workflow comment at line 12 explicitly states "AppArmor version must be coordinated with ABI specified in profile."

GitHub's ubuntu-latest may not currently point to Ubuntu 24.04, which would cause this workflow to fail or behave incorrectly. The runner should remain pinned to ubuntu-24.04 to ensure the correct AppArmor version is used.

Suggested change

	os: ubuntu-latest # apparmor 4
	os: ubuntu-24.04 # apparmor 4

This needs to remain at 24.04 and not be updated to latest. See comments.
