I love to make informed decisions.  It happens to be that I have already
considered some of your suggestions but decided to do things differently
before I sent my first email here.

Your comments are helpful and I really appreciate them.

Since I get a lot of HTTP 502 from cgit[1] of NonGNU ELPA repo, I choose
to check it by cloning the repo with:

  git clone --single-branch git://git.git.savannah.gnu.org/emacs/nongnu.git

The latest commit is the one adding codex-ide and hermes.  Also, I do not
see project-store in the repo.  Is something wrong?

Nix can be seen as two parts:

- The first part generates derivations (.drv files) from something
  higher-level.
- The second part builds derivations into store objects.

There are some projects inspired by Nix.  For the first part, some of
them compile Nix language into derivations; others compiles other
languages into derivations, such as Guile for Guix, Typescript for Garn
(there is a talk about it in NixCon2025) and Janet for Hermes[2].
Except for Hermes, they seem to keep their implementations of the second
part compliant with Nix's.

There are also projects that are more different, such as Tangram and
Brioche.

I am not familiar with all of them so take my words with a grain of salt.

I use "the store module" to refer to data model and
operations/interfaces of the store layer.  Guix seems to just call it
"the store"[3].

I highly recommend the "Learning the Nix Store Layer" talk of NixCon2022
if you are interested in the second part.  The speaker thinks the store
model as a "narrow waist" in Nix ecosystems, just like TCP/IP in the
network layer.
