So you've got a stable/testing/unstable system on hd1?

And a 14-month old bullseye system on hd0, which is currently running?

The system has booted into a bookworm Grub (deb12u1). It would appear
that your MBR/UEFI has booted into a grub.cfg that isn't the one
created above, ie on the other disk. After all, that Grub menu looks
as if it was created on a system that (a) isn't bullseye, and (b) ran
os-prober to produce its bullseye lines 3 and 4.
Cheers,
David.
