+# Unprivileged wrapper for the generation tests.
+#
+# Upstream's image runs as root and leaves /.local root-owned, so running
+# it as the host user fails before generation starts (PermissionError on
+# /.local) and running it as root leaves root-owned seeds in the mounted
+# output directory. Two lines fix both, and they are the only difference
+# from the base image.
+#
+# Built once per Archipelago tag, not per apworld test, so the cost of
+# the recursive chown is paid once and amortised over a few hundred
+# generations.
