Oh, maybe there’s something wrong with that file.  I’m sorry.

Have you taken a look at https://hydra.nixos.org yet?  This is the hydra
instance of the Nix project.  (We use an older variant of the same
software on https://hydra.gnu.org, but it’s not very responsive.)

On https://hydra.nixos.org/jobset/nixos/staging you can see a particular
branch of the nixos project.  It lists evaluations, displays the number
of successes, failures, and pending builds, and it links to a detailed
overview of the evaluation.

For example, at https://hydra.nixos.org/eval/1459429 we see the list of
builds that are associated with a particular evaluation and we can
follow a link to a description of that build.  The build page shows us
some information about the derivation/package and links to the build
logs.

It also shows us when the build first failed, what change in the
repository lead to the build failure, and so on.

We are not just looking for a status page that displays the database
contents.  Some of the bits of information have to be derived from more
than one database record.  When you compare the current state of the
Cuirass web interface to that of Hydra, what do you see is still missing
and should be implemented next?  Could you identify the top 5 features
that you think are missing and could be added to Cuirass?
