# Gitea Actions — build the UE 5.7.4 editor binaries on a Windows host-mode runner
# and publish them to the GCS artifacts bucket (the poor-man's-UGS producer side).
#
# Runner: registered on a Windows box with label `windows:host` (host mode, NOT a
# container) so it can use the installed UE 5.7.4 + VS 2022 + gcloud.
#
# NOTE (proof shortcut): BUILDGRAPH_SCRIPT points at the build-infra folder on the
# runner's local disk, because for now the runner and build-infra live on the same
# machine. For a real multi-agent fleet, vendor BuildEditor.xml into this repo (or a
# submodule) so any runner has it — see build-infra/RUNBOOK.md §9.
