  OK... I've spent a fair bit of time looking into this.  I am interested in making FreeRADIUS better, after all.

  That's wrong.  It's not a valid attribute reference.

  Most of the rest of the changes are needlessly complicated.  You don't need to delete the Called-Station-SSID and then re-add it.  You can just use ":=", as that's it's documented behaviour.

  You don't need to check for the existence of the Called-Station-Id, you can just use it in the Reply-Message

  And it works in my tests, with the exception of the wrong attribute reference above.

  You're using 3.0.4.  It works in 3.0.8.  Upgrade.
