This was just the auto-generated name, but int the course of investigating it I actually solved the problem. First, here's the output of installkernel.

sudo installkernel

It says "Warning! Kernel command "root=" is missing from loaded configuration!", which I had dismissed for two reasons:
1. It dracut "root=UUID=c7085028-6dfa-4b82-911e-b176b9cd1f38 rootfstype=bcachefs rootflags=rw,noatime,noshard_inode_numbers" just a few lines prior, which it inferred from the fstab. Which told me that I didn't need to specify the root device.
2. When booting, OpenRC prints "setting hostname to "fixti" from /etc/hostname" which tells me that it is able to find the root partition and read data off of it.
Anyway despite that, I was wrong, and copying the above "root=..." line into /etc/default/uefi-mkconfig actually fixed the problem. Now my efi boot entries look like this:

Those numbers at the end are hex-encoded UTF-16 for root=UUID=c7085028-6dfa-4b82-911e-b176b9cd1f38 rootfstype=bcachefs rootflags=rw,noatime,noshard_inode_numbers.
Apparently "2000" decodes to a character called "EN QUAD", a non-printing space character with a specific width used in typography. This seems pretty strange, maybe it's a bug.
I still don't actually understand why the problem occurred. Why OpenRC defaulted to shutting down in the situation I created for it. But at least It's fixed.
