  "summary": "Verified backend + frontend for the new 'Completitud de Datos' panel in Gestión 4SAT dashboard. Backend: 20/20 pytest tests passed against GET /api/gestion4sat/dashboard, validating shape (empresas_completas, empresas_sin_razon, empresas_sii_no_encontrado, porcentaje, ultimo_enriquecimiento{estado,actualizados,finished_at}), correct porcentaje math (round(completas/total*100)), that counts sum to total_empresas, auth guard (401/403 without token), and regression of all existing KPIs (total_empresas, dispositivos_*, servicios_*, alertas_pendientes, top_empresas). Live data: 170 total, 169 completas, 1 sin razón, 0 sii_no_encontrado, porcentaje=99. Frontend: admin4sat@demo.com auto-redirects to /gestion4sat/dashboard with data-testid='g4s-dashboard'. datos-completitud-card renders 99% progress ring (emerald-green, matching >=80% threshold), 3 stats columns (Completas 169 / Sin razón social 1 / No en SII 0), 'Enriquecer' button (data-testid='btn-ir-enriquecer') visible because empresas_sin_razon>0, last enrichment info line 'Último enriquecimiento: 11-07-2026, 7:34:06 p. m. · 0 actualizados' visible. Click Enriquecer navigates to /gestion4sat/importar. All 8 existing KPI cards + Top Empresas + Servicios Pendientes render correctly (regression OK).",
