So things to do to help triage the problem:
* Keep a continuous eye on the temperature
In a console window
* Using pitemp.sh note the temperature at boot & after 1/2 hour
* Remove the DRAWS hat, boot, note the temperature & after a 1/2 hour
* When you re-install DRAWS hat check for being off by one on the
* Power down RPi with DRAWS hat, let RPi cool down
At cool power up is the DRAWS hat working?
* just run alsa-show.sh and look for something reasonable.
* Do a close visual inspection of the DRAWS hat & RPi.
* Anything look charred?
* Feel the USB cable powering your RPi does it feel warm?
More things to try as you suggested.
The Pi did not seem to be acting sick by itself.
Could it be the power source or should I not trust the PI at all?
It is suspicious to me that the RPi gives the low voltage symptom
(lightning bolt). Is it the power supply or is the DRAWS card loading
the RPi voltage source?
The following is not a bad idea but I would confirm that there is not
something seriously fried on the DRAWS hat first.
If you think I can trust the Pi, I could always take a different power
supply tactic and use the buck supply line in the DRAWs card for the Pi and
feed the display from a separate line.

Hmmm... and Pi was feeding the DRAWS card, not visa-versa... but that should
not be causing the CPU to overheat!

Ya that was a little too dramatic. While your RPi is running much hotter
than any of mine on the bench @ 69C it won't catch fire. It looks like the
"official" operating limit is around 85C and will start to thermally
throttle at around 82C which your RPi has already hit.
So yes your RPi is running suspiciously hot and no it probably won't catch

First Pass at your console output.
Drivers are loading fine, no software faults, hardware is definitely
stressed, gps not working, codec not working
Second Pass at your console output.
Your RPI is running at over 150F and will soon catch fire if you don't
DISCONNECT THE POWER. From vcgencmd throttled=0xd0005
- Temperature limit has occurred
- Throttling has occurred
- Under voltage has occurred
The RPi is currently running throttled & under-voltage
Just recently I have seen someone else's RPi start running really hot.
Also check your 5V RPi wall wart. Is it warm/hot?
See embedded below.

Should I wait for image 16, try another install then?
Do you see something that got flipped the wrong way by me whenSoftware config looks OK.
running ./app_config.sh core?
