Evap Not Ready - Need help diagnosing

Hey guys, new to me 2006 Cayman S that's going to be my track car. I'd like to get it to pass the state inspection. It doesn't have cats, so I know that's never going to be in the ready state, but I can still pass as long as I don't have TWO items not ready. So evap...

 

I guess the gas cap is the most common failure point, but mine LOOKS tight and in good shape. Haven't replaced it yet though. I have a PIWIS and I'm trying to learn  how to use it. Today I discovered it has a "Short Test" feature that goes through a bunch of diagnostic tests. The first several passed fine. There were a few related to the evap system (I believe) that did not. Let me show you a few screenshots and see if anyone here knows what I should check or maybe how I can use the tools I already have to further diagnose this.

 

Any help/tips greatly appreciated. I will, of course, eventually make a video for my channel to help the next guy that runs into this! Doesn't seem to be much info out there (that's clear enough for me to follow at least)
