Why no coreos version in 'ostree remote refs fedora'

Ask Fedora

I am running a baremetal server with fedora coreOS 41, and was about to rebase it to 42.
But I see it is already 42, how could it happened?

root@mostro:~# cat /etc/fedora-release 
Fedora release 42 (Adams)

My intention was to follow Rebasing to New Versions, but when I do this command I see no specific version for coreos:

root@mostro:~# ostree remote refs fedora | grep 'x86_64/coreos'
fedora:fedora/x86_64/coreos/next
fedora:fedora/x86_64/coreos/stable
fedora:fedora/x86_64/coreos/testing

while for silverblue for instance I see all versions, ie 40,41,42.
Why no specific version for fcos?

CoreOS doesn’t use numbers. CoreOS Stable uses the latest stable release of Fedora, currently 42. CoreOS Testing includes updates that are in testing and to be released in Stable. CoreOS Next lets you test the next release early.

So basically, currently
CoreOS Stable = Fedora 42.
CoreOS Testing = Fedora 42 with Testing updates
CoreOS Next = In development version of Fedora 43 (or Rawhide?)

Adding to that. These docs pages might help clear some things up:
