Quick history, the system was rejecting ssh connections, and was not
responding to ACPI shutdown, so I had to force power off.
On restart, everything looked ok, but when I did a scrub, the system
quickly reached a point of forced read-only., (kernel Ubuntu 4.15.0-52)
I installed a current Arch for recovery, (kernel 5.3.1 and btrfs-progs
5.2.2)
Here is the result of btrfs check

As that btrfs check shows, your extent tree is corrupted.
Quite some backref is lost, thus no wonder some write opeartion would
cause problem.
In that case, it looks like only extent tree is corrupted, and no
transid error.

This is itself a back-up system, but not wishing to tempt fate, I'm
going to have to create a working substitute before I do anything risky
with it. It would take me several days and lots of travel to re-aquire
them.
Any idea what could have happened? The data and meta data should be
raid1, and none of the drives have any io errors of any kinds in their
SMART log.
Thank you for your guidance.

Maybe some existing bugs, since it's an older kernel.
But at least, no tree relationship corruption. So you should be pretty OK.
You could try btrfs check --init-extent-tree, as I see no error report
from fs tree check.
Since it's extent tree only mismatch, you can in fact mount the fs RO
and grab all data.

It's indeed a symptom of btrfs kernel module bug. But at least looks
repairable.

As advertised, btrfs --check repair restored the FS to full function.
A follow-up scrub even found and corrected some corrupt data on one of
the disks, that went completely unreported by the disk itself. So,
despite this hiccup, BTRFS did it's job admirably.
Whenever I do any further btrfs check after cleanly unmounting the
filesystem, I get this error:
cache and super generation don't match, space cache will be invalidated
Even mounting with clear_cache,nospace_cache , (then mounting again with
space_cache=v2) does not remove this warning. But it doesn't seem to be
causing any problems.. There are no warnings about the space cache in
the dmesg log when the filesystem is mounted.

Yep, btrfs check --repair is getting better and better.
As long as btrfs check (no --repair) after --repair reports no error,
you're completely OK to go.
But as you already found, btrfs check (by default) only cares metadata,
while ignores all data, so you still need another scrub to fix data error.
In fact you can use --check-data-csum to make btrfs check to
check/repair data csum error too. (kinda like scrub).

It's not an error, just a warning.
Kernel will just discard that cache.
