Thanks that is a pretty concise description of the state of things.

How's this for confusion? I rebooted and plugged into the front Type-c,
haven't changed anything, not the cabling, not the bios. No joy this time
not even the repeated bind unbind messages I usually get, udevadm monitor
saw nothing.

I then plugged into the Type-c on the PCI-e card directly. This time it
recognized the nvme ntfs partition as sdb. I'm wondering if fuse handles
something, maybe xhci mode alias which I could configure when I try to make
this an LVM boot device again.

udevadm monitor
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

Gnome-disks now shows sdb1
Contents NTFS — Mounted at /run/media/R3eiter/Zomey512Gb

Now it is possible that the tolerances between the MB Type-c the PCI-e
cards type-c and the front breakout Type-c are all slightly different and
this is causing a SHINE single high-level impulse noise.

This last semi-sucess was a live hotplug. I'm going to reboot and see if it
mounts on boot, but at this point I'm not holding my breath.
