Eligibility is the most important stage and if you have passed it then you don't really need Gcms Notes and the application will takes its course till approved. To determine if its passed by an officer; if Security is in progress then it's a clear signal that Eligibility has been passed by an officer. Sometimes Eligibility may have been passed by an officer and security has not started due to administrative delays What you can instead of Gcms Notes is that you can send a web form and see what they have to say about Security.
Will they respond to the web form query since the application is within the normal processing times? In the web form page they state that they won't if this is the case.
