Backend: 5/5 pytest tests passed for /api/gestion4sat/scraper/rut/{rut}, /api/guias/consultar-rut/{rut}, auth guard, invalid RUT handling, and cross-module cache_rut_sii sharing. Frontend: 7/7 Playwright tests passed covering admin4sat login redirect, /gestion4sat/empresas load, 'Nueva Empresa' dialog, btn-consultar-sii presence, RUT lookup auto-populates nombre_cliente + razon_social, spinner→search icon transition, and regression on cross-module auto-redirect.",
