+ * MANUAL TEST INSTRUCTIONS FOR DOUBLE-DELETED EMAIL SCENARIO:
+ *
+ * To test the double-deletion bug fix manually:
+ *
+ * 1. Create a double-deleted email in the database:
+ *    ```sql
+ *    UPDATE cms_users
+ *    SET email = CONCAT(email, '.deleted.', id)
+ *    WHERE id = 100000005
+ *    AND email LIKE '%.deleted.%';
+ *    ```
+ *    This simulates the bug where a user was deleted twice.
+ *
+ * 2. Verify the email now has double suffix:
+ *    ```sql
+ *    SELECT id, email FROM cms_users WHERE id = 100000005;
+ *    ```
+ *    Should show: deleted@deleted.co.deleted.100000005.deleted.100000005
+ *
+ * 3. Run the fix cron job:
+ *    Visit: http://localhost:8100/cron/fix-double-deleted-emails.php
+ *    (Make sure db_database is 'dropapp_dev' in config)
+ *
+ * 4. Verify the email is fixed:
+ *    ```sql
+ *    SELECT id, email FROM cms_users WHERE id = 100000005;
+ *    ```
+ *    Should show: deleted@deleted.co.deleted.100000005
+ *
+ * 5. Try to reactivate the user through the UI:
+ *    - Go to Manage Users > Deactivated tab
+ *    - Select "Deleted User"
+ *    - Click "Activate"
+ *    - Should succeed without errors
+ *    - Email should be: deleted@deleted.co
