The Goal: Moving from simple "Success/Fail" keys to intelligent account sorting based on server status codes and hidden headers.
The Workflow:

1. Status Code Filtering: Instead of searching for the word "Logout," set your KeyCheck to look for
   Response Code = 200
   (Success) vs
   401
   (Unauthorized).
   
2. Header Analysis: Many modern sites use headers like
   X-Account-Type: Premium
   to define access.
   • Action: Add a KeyCheck that scans Headers, not just the HTML body.
     
3. The "Custom" Key: If a login works but the page contains "Please verify your email," use the CUSTOM status. This separates "Hits" from "Verification Required" accounts.
