+# 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.
