Like my 7 year old HP laptop, the group of bad keys have failed again. 
I removed the bottom cover and cleaned the keyboard ribbon cable with a Q-tip and Corrosion-X to no avail. After replacing the cover, I noticed that I can get the keys to function intermittently by applying a twisting force to the case/chassis so this must be a mechanical issue and it was probably aggravated by the epoxy repairs I made to the broken captive nut anchors. My repairs slightly changed the fit of parts and, in turn, the stress and strain on an electrical keyboard connection. I can't identify anything specifically that's amiss though. Still, it should not do this. The chassis is not visibly or detect-ably misaligned.
I hope I'm not throwing more good money after bad but, with this newly discovered symptomatic detail, I might order a new keyboard/palm case. To be fair to my PBP, i've only purchased a replacement bottom cover (screw holes in the original had enlarged) and associated screws and spacers in the couple of years I've owned it. At least my PBP and Pinephones have been good for user-serviceability.
