Good points, thank you. Those logs are hard to read! I did do one restart in safe mode, I read somewhere that can fix some things like this but it's probably a long shot. It's running normally now.
I'll check it out in the morning. If the watchdogd panic reoccurs I've decided the best thing to do is a squeaky-clean install. I'll do an NVRAM reset, erase the partition, reinstall from USB drive, reapply post install patches. It'll take a while but it might turn out to be faster than chasing a discrete fix.
One thing I've noticed since installing Monterey 12.5 with OCLP 0.4.10 is the About This Mac panel is showing both GPUs, I don't recall ever having seen that before.
