There is no such document.  Here's how it's set up:

ci.guix.gnu.org is installed and configured from the hydra/berlin.scm
code in the maintenance.git repository[1].
"hydra/modules/sysadmin/packages.scm" defines "guix-cran-scripts", which
is built from the contents of its dedicated repository[2].

This package is used in "hydra/modules/sysadmin/services.scm" to define
two service types: "guix-cran-service-type" and
"guix-bioc-service-type".  These extend the mcron service type to run
the "update.sh" script.  The script acts on /var/lib/guix-cran and
/var/lib/guix-bioc, the respective home directories of the guix-cran and
guix-bioc user accounts.  The result of running the update script for
CRAN and Bioconductor is a new commit for each of the repositories at
[3] and [4].

The script commits and pushes to these repositories.  This means that
those user accounts have been granted push access via SSH keys.  These
keys obviously must stay secret.
