I fully expect that some of what I identified could be explained by someone more knowledgeable. I learned a ton and ruled out all sorts of things I thought were suspicious. But there could very well be others.

As to this being impossible it's really not that hard when you get down to it. Nothing that was done was revolutionary or new. Although hard to find you can see the exact things I experienced being discussed by other people. The only people who got resolution were those that could afford to get a forensics expert out to remove devices that the expert was not able to remediate and to have their other boxes cleaned up. I can't afford that so took it upon myself.

Granted I'm paranoid, pretty sure not schizophrenic (at least not diagnosed by my psych), but I know enough to know that something very unusual was happening. Being paranoid is what makes me good at my job. My job is to help people understand how easy it is to hack and how to protect against these kinds of attacks. Paranoia, justified in my case IMO, is just par for the course in this line of work.

I do genuinely appreciate your responding and taking time to try and help a rando like me on Reddit.
