  "summary": "End-to-end backend + frontend testing of the 8 improvements for the Gestión 4SAT module. All 9 backend pytest cases pass (test_g4s_improvements.py) covering: (1) Scraper /api/gestion4sat/scraper/patente/BBFL71 returns cached datos with marca=NISSAN, modelo=TERRANO DX D CAB 2.5, anio=2008, color=BLANCO, tipo=CAMIONETA, source=cache; (2) GET /api/gestion4sat/dispositivos/buscar-imei?q=866 returns predictive resultados array (≤10) filtered by IMEI, and correctly enforces min 3 chars + route precedence over /{dispositivo_id}; (3) GET /api/gestion4sat/sync-log returns logs array (empty by default); (4) PUT /api/gestion4sat/dispositivos/{id} persists patente/vehiculo_marca/notas + 404 on unknown id; (5) DELETE /api/usuarios/{id} works (first call 200, repeat 404); (6) PUT /api/gestion4sat/config with tabla_font_size persists. Frontend on /gestion4sat/dispositivos as admin4sat: full ICCID displayed (15-digit numbers, no slice), edit-button on every row, both 'Log Sync' + 'Sync → 4sat.cl' toolbar buttons render; edit dialog opens with all expected fields (Patente, Estado, GPS Marca/Modelo, Vehículo Marca/Modelo/Año/Color/Tipo, ICCID, Notas) and Guardar saves. Sync log dialog opens showing 'Sin registros de sync' (empty state). On /gestion4sat/servicios/nuevo: input-imei triggers predictive dropdown with 10 devices when typing '866' (IMEI+patente+empresa visible), Lat/Lng inputs (input-lat, input-lng) accept manual entry and 'Ver en Google Maps' link appears (href=https://www.google.com/maps?q=lat,lng). On /gestion4sat/config: 'Tamaño de Letra en Tablas' selector present, users table shows edit + delete (trash) icons per row, 'Integración 4sat.cl' section with Email/Password/API Hash fields present.",
