Move modules/backend to 528e3a4 (Backend #239), which rejects empty or foreign conversationId when creating a surface via POST /api/surfaces. Why: Dev must carry the Backend conversation-required fix. Evidence: Backend #239 CI success at 954e744; agent-exec unit dev-svc-superadmin-surface-backend-repin (cursor, authorized fresh rerun, terminal=success). Impact: documentation pin / gitlink only.
