If you go to a patch, like: https://patchwork.cbaines.net/patch/20613/
there are some links in the Checks section. The "View comparison" link
takes you to a Guix Data Service instance, the "View Git branch" link
takes you go a Git repository containing the patches, and the "View
Laminar job" link takes you to the job in Laminar that tried to apply
the patches.

I realise that it's not easy enough to find this out, but the Guix Data
Service provides substitutes for the derivations it knows about. It
stores all the information about derivations, and it also stores the
sources referenced by the derivations.
This means it can provide substitutes for these store items. Take mxnet,
if you trust the key (which can be found here
https://guix-patches-data.cbaines.net/substitutes ), then you'll be able
to do:
guix build --substitute-urls="https://guix-patches-data.cbaines.net"
/gnu/store/9xcmc4z6w0brg17l1frz6blg79wgf7yi-mxnet-1.6.0.drv
As I understand it, Guix will download the derivation graph from the
Guix Data Service until it has the derivation locally, then it will
build it as normal.
Hope that makes sense?
