dependency PRs can be outdated but still mergable.
Ideally they should be tested not at PR's head — which is simply the author's branch — but at the merge-to-be that would happen if merged now.
Github exposes magic pull/NN/head and pull/NN/merge refs, and I was hoping I can just use the later.
Alas, somehow it's not a "real branch", doesn't work in git checkout --branch pull/42/merge nor in Gemfile gem git: ..., ref: "pull/42/merge" :-(
