Nothing I am aware.  I mean nothing using ~/.cache/guix/checkouts.

However, it is easy to run the same thing from the development checkout.
I had (still have?) some Bash script for bisecting.

Well, I do not remember and I have not checked if the returned code of
“guix weather” is specified.  If not, it could make the Bash script more
annoying.

Last, this bisection of build failures is already provided by the Data
Service. For instance, see [1].  It currently only uses the Bordeaux
build farm and probably some work to add Berlin but doable, I guess.

There is many tools from the Nix ecosystem that could be implemented as
Guix extensions.  That’s where Guix shines: it is continuous from core
Guix to package definition or to scripts.
