I’ve owned and deployed a lot of pi, every model, and in my experience when I have similar instability as you described its related to the sdcard. Either the sdcard itself or the tray soldered to the pi. I had one pi that would corrupt the sdcard without fail after 2 months and I played with bending the sdcard metal tray inward a little to help press the card better into the contacts and the problem went away. Try fiddling with the sdcard holder or different sdcards.

I’m almost 40 and now just realizing my insistence on how to structure all my folders and notes is actually an ISO standard. Way to go me.

I read that entire article, thank you. Explains a bit why the company I work for seems really hesitant to hire more software engineers.
