Not sure if I undertand that you meant, here.
Sorry for my unclear words.
Simply speaking, I suggest you to stop current running check.
Then, clone above branch to compile binary then run
'btrfs check --mode=lowmem $dev'.
I understand, I'll build and try it.
This filesystem is trash to me and will require over a week to rebuild
manually if I can't repair it.
Understood your anxiety, a log of check without '--repair' will help
us to make clear what's wrong with your filesystem.
Ok, I'll run your new code without repair and report back. It will
likely take over a day though.
Well, it got stuck for over a day, and then I had to reboot :(

make[1]: Nothing to be done for 'all'.
However, it still got stuck here:
Thanks, I saw. Some Clues found.
Could you try follow dumps? They shouldn't cost much time.
#btrfs inspect dump-tree -t 21872 <device> | grep -C 50 "374857
EXTENT_DATA "
#btrfs inspect dump-tree -t 22911 <device> | grep -C 50 "374857
EXTENT_DATA "
Thanks,
