# because we need repository secrets for that, which pull_request doesn't allow from forks.
# However, it's very important that we don't run code from forks without sandboxing it,
# because that way anybody could potentially extract repository secrets!

# To prevent running untrusted code from forks,
# pull_request_target will cause the base branch to be checked out, not the PR branch.
# This is exactly what we want in this case,
# because the sync-pr.sh script cannot be run sandboxed since it needs to have side effects.
# Instead, the script itself fetches the PR, but then runs its code within sandboxed derivations.
