I suspect that GHC was never built by Cuirass, but that somebody logged
in to the build server and invoked `guix build ghc
--max-silent-time=99999`.

There's no logs of a successful build of GHC 9.2.5 available through the
Cuirass web interface, which is a clue that my hunch is correct. Builds
performed "by hand" don't appear in the web interface.

https://ci.guix.gnu.org/search?query=spec%3Amaster+ghc-9.2.5

Are we sure that Cuirass honors the max-silent-time property? If I
remember correctly, it did not do so in the past.
