OK, good.

Hum, I miss why you get all that. It’s weird that you have three
profiles here.
Could you provide the output of
guix gc --derivers $inferior
?
> $ profile=$(guix gc --referrers $inferior)
Because you all these derivations and 3 profiles above, here the
variable $profile isn’t the profile that I expected…

…however this is also unexpected. Somehow, I would expect something
like:
--8<---------------cut here---------------start------------->8---
$ guix gc --references
/gnu/store/h73qvv7iljwk2fsz84q282jmr02jfg8y-fonts-dir.drv

Hum, this error is unexpected. Could you report the output of
guix gc --list-live | grep
0y5pd6dyzh2bf0xghp35pnhhpzp6fl39-fonts-dir.drv
and
guix gc --list-dead | grep
0y5pd6dyzh2bf0xghp35pnhhpzp6fl39-fonts-dir.drv
? And if both outputs are empty,
guix gc --list-live | grep fonts-dir\.drv | wc -l
and
guix gc --list-dead | grep fonts-dir\.drv | wc -l
?

Well, I’m interested all the output. :-)
For example, I get this:
--8<---------------cut here---------------start------------->8---
$ guix gc --references $(guix gc --referrers $(guix time-machine -C
channels.scm))
/gnu/store/30j7azqpy63m251nr887g748w18cki6r-guix-science

/gnu/store/wpdq87d6azndvb94cfigsfbh2ph7j9aj-guix-package-cache
--8<---------------cut here---------------end--------------->8---
And I was expecting something similar. Since you get many derivations,
what is the running version of guix-daemon? Are you running an
unprivileged daemon [1]?

I think something is twisted with your current Guix. And it’s hard to
find… especially remotely. :-) Sorry for the inconvenience.
What do you get if you run
guix time-machine -q -- time-machine -C channels.scm -- build python-jax
? Or
guix time-machine -q --commit=52d82e555119c013cfbf9ad7671a56dc6c1a1f16 \
-- time-machine -C channels.scm -- build python-jax
?
