well as I said before talk to your Lawyer. I got my felony in Medford/Jackson County and as I stated before the judge put in my conditions that I was allowed to possess and obtain marijuana while I was under state supervision. As long as that was in my paperwork the PO had to go along with it. I was still subject to home inspections and piss test (neither were done the entire time). Your orientation with your PO should have stated that you have to cooperate with Law Enforcement whenever confronted by them to include your PO.
This is what I had done when I got sentenced to avoid a situation like yours.
You my friend, are a spark of hope in this bleak abyssal void of legal muck iv been floating around in as of late!
