Hi,
Well, I do not know if it is a bug or if I misuse something. Feel free
to close if I am missing a point.

Well, that’s just a luck that both commit hash matches.
Now, what I am missing. The manual says:
As for ‘guix pull’, the absence of any options means that the latest
commit on the master branch will be used. The command
guix time-machine -- build hello
will thus build the package ‘hello’ as defined in the master branch,
which is in general a newer revision of Guix than you have installed.
Time travel works in both directions!
and I get:
--8<---------------cut here---------------start------------->8---
$ guix time-machine -- describe
guix e499cb2
repository URL: https://git.savannah.gnu.org/git/guix.git
commit: e499cb2c12d7f1c6d2f004364c9cc7bdb7e38cd5
--8<---------------cut here---------------end--------------->8---
But I do not understand from where this commit hash is coming from. And
please note that this commit seems coming from my previous experiments
reported in #63667 [1].
Well, the last commit seems a9cde26133b,
--8<---------------cut here---------------start------------->8---
$ git -C
~/.cache/guix/checkouts/pjmkglp4t7znuugeurpurzikxq3tnlaywmisyr27shj7apsnalwq
log origin/master --oneline -1
a9cde26133b (origin/master, origin/HEAD) gnu: Add mouseloupe.
--8<---------------cut here---------------end--------------->8---
Therefore, let create a Guix revision:
--8<---------------cut here---------------start------------->8---
$ guix time-machine --commit=a9cde26133b -- describe
guix a9cde26
repository URL: https://git.savannah.gnu.org/git/guix.git
commit: a9cde26133bd98498869a3528d9dff0d3f456a96
--8<---------------cut here---------------end--------------->8---
However, still this e499cb2 one:
--8<---------------cut here---------------start------------->8---
$ guix time-machine -- describe
guix e499cb2
repository URL: https://git.savannah.gnu.org/git/guix.git
commit: e499cb2c12d7f1c6d2f004364c9cc7bdb7e38cd5
