- ✅ Ticket 1.1: Estructura Clean Architecture en backend - ✅ Ticket 1.2: Schemas Zod compartidos - ✅ Ticket 1.3: Refactorización drugs.ts (1362 → 8 archivos modulares) - ✅ Ticket 1.4: Refactorización procedures.ts (3583 → 6 archivos modulares) - ✅ Ticket 1.5: Eliminación de duplicidades (~50 líneas) Cambios principales: - Creada estructura Clean Architecture en backend/src/ - Schemas Zod compartidos en backend/src/shared/schemas/ - Refactorización modular de drugs y procedures - Utilidades genéricas en src/utils/ (filter, validation) - Eliminados scripts obsoletos y documentación antigua - Corregidos errores: QueryClient, import test-error-handling - Build verificado y funcionando correctamente
