 ## Changelog
 
+### 2025-01-04
+- Completed fiscalPeriods.service.ts migration to TypeORM
+  - Replaced raw SQL with Repository pattern for FiscalYear and FiscalPeriod
+  - Implemented QueryBuilder for complex queries with joins (fiscalYear, company)
+  - Preserved database function calls for close/reopen operations using repository.query()
+  - Preserved all critical business logic:
+    - Date overlap validation using PostgreSQL OVERLAPS operator
+    - Monthly period generation algorithm
+    - Period statistics calculation
+    - User name lookup for closedBy field
+  - Manual snake_case to camelCase mapping for database function results
+  - Converted DTOs to camelCase
+  - Added comprehensive logging
+- Completed payments.service.ts migration to TypeORM
+  - Created PaymentInvoice entity for payment-invoice junction table
+  - Replaced raw SQL with Repository pattern for Payment, PaymentInvoice, and Invoice
+  - Used QueryRunner for transaction management (reconcile, cancel operations)
+  - Used QueryBuilder for main queries, raw SQL for cross-schema joins (partners, currencies)
+  - Preserved all critical business logic:
+    - Payment reconciliation workflow with invoice validation
+    - Invoice amount updates (amountPaid, amountResidual, status)
+    - Partner validation (invoice must belong to same partner as payment)
+    - Amount validation (reconciled amount cannot exceed payment or invoice residual)
+    - Status transitions (draft -> posted -> reconciled -> cancelled)
+    - Only draft payments can be modified/deleted
+    - Reverse reconciliations on cancel
+  - Converted DTOs to camelCase
+  - Added comprehensive logging
+- Completed invoices.service.ts migration to TypeORM
+  - Replaced raw SQL with Repository pattern for Invoice and InvoiceLine
+  - Used QueryBuilder for main queries, raw SQL for cross-schema joins
+  - Preserved all critical business logic:
+    - Tax calculation integration with taxesService
+    - Invoice status workflow (draft -> open -> paid/cancelled)
+    - Sequential number generation (INV-XXXXXX / BILL-XXXXXX)
+    - Line management with automatic total recalculation
+    - Payment tracking (amountPaid, amountResidual)
+  - Converted DTOs to camelCase
+  - Added comprehensive logging
+- Completed journal-entries.service.ts migration to TypeORM
+  - Replaced raw SQL with Repository pattern
+  - Used QueryRunner for transaction management (create, update)
+  - Implemented QueryBuilder for complex queries with joins
+  - Preserved all accounting logic:
+    - Double-entry balance validation (debits = credits)
+    - Minimum 2 lines validation
+    - Status transitions (draft -> posted -> cancelled)
+    - Only draft entries can be modified/deleted
+  - Converted DTOs to camelCase
+- Completed journals.service.ts migration to TypeORM
+  - Replaced raw SQL with Repository pattern
+  - Implemented QueryBuilder for joins
+  - Converted DTOs to camelCase
+- Completed taxes.service.ts migration to TypeORM
+  - Replaced raw SQL CRUD with Repository pattern
+  - Used In() operator for batch tax lookups

+## 6. BLOQUEADORES Y RIESGOS
+
+### 6.1 Bloqueadores Activos
+
+_Ninguno_
+
+### 6.2 Riesgos Identificados
+
+| Riesgo | Probabilidad | Impacto | Mitigacion |
+|--------|--------------|---------|------------|
+| react-grid-layout deprecado | BAJA | MEDIO | Monitorear alternativas modernas |
+| Falta de tests unitarios | MEDIA | MEDIO | Agregar tests en Sprint futuro |
+
+---
+
+## 7. LECCIONES APRENDIDAS
+
+### 7.1 Lo que funciono bien
+
+1. Estructura feature-first permite encapsular toda la logica del modulo
+2. Zustand simplifica el state management vs Redux
+3. Recharts provee charts profesionales con minima configuracion
+4. react-grid-layout funciona bien para layouts drag & drop
+
+### 7.2 Lo que se puede mejorar
+
+1. Agregar tests unitarios para widgets
+2. Documentar API de configuracion de widgets
+3. Agregar storybook stories para componentes
+
+### 7.3 Acciones para siguiente sprint
+
+| Accion | Responsable | Prioridad |
+|--------|-------------|-----------|
+| Implementar Report Builder UI | Frontend-Agent | ALTA |
+| Agregar tests de widgets | Testing-Agent | MEDIA |
+| Agregar exportacion de dashboards | Backend-Agent | MEDIA |
+
+---
+
+## 8. PLAN PARA SIGUIENTE SPRINT (Sprint 10)
+
+### 8.1 HUs Candidatas
+
+| ID | Titulo | Prioridad | Dependencias |
+|----|--------|-----------|--------------|
+| US-MGN009-003 | Report Builder UI | P0 | RF-REPORT-003 |
+
+### 8.2 Objetivos Propuestos
+

+
+## 9. Recomendaciones
+
+### 9.1 Inmediatas
+1. **Agregar RLS a tablas nuevas**: Las 9 tablas nuevas necesitan politicas RLS
+2. **Agregar indices**: Crear indices para FK fields en tablas nuevas
+3. **Actualizar domain models**: Sincronizar documentacion de modelos de dominio
+
+### 9.2 Corto Plazo
+1. **Script de migracion**: Crear script consolidado para aplicar cambios en produccion
+2. **Tests unitarios**: Crear tests para funciones button_approve/button_confirm
+3. **Documentacion API**: Actualizar documentacion de endpoints afectados
+
+### 9.3 Mediano Plazo
+1. **Implementar P2**: Priorizar COR-014, COR-015, COR-016
+2. **Validacion E2E**: Tests de flujo completo PO -> Recepcion -> Factura
+
+---
+
+## 10. Conclusion
+
+La FASE 7 de validacion confirma que todas las 14 correcciones P1 han sido aplicadas correctamente a los 4 archivos DDL del modulo ERP-Core.
+
+**Estado Final:** VALIDACION EXITOSA
+
+**Proximos Pasos:**
+1. Crear script de migracion consolidado
+2. Actualizar documentacion downstream
+3. Planificar implementacion de correcciones P2/P3

+## 6. IMPACTO DE CAMBIOS
+
+### 6.1 Archivos de Alto Impacto (Modificar con cuidado)
+
+| Archivo | Impacto | Razon |
+|---------|---------|-------|
+| backend/src/app.ts | ALTO | Entry point, routing |
+| backend/src/modules/auth/entities/*.ts | ALTO | Entidades compartidas |
+| frontend/src/app/router/routes.tsx | ALTO | Routing global |
+| frontend/src/shared/stores/useAuthStore.ts | ALTO | Estado de autenticacion |
+| database/ddl/01-auth.sql | ALTO | Schema base |
+
+### 6.2 Archivos de Bajo Riesgo (Safe to modify)
+
+| Archivo | Impacto | Razon |
+|---------|---------|-------|
+| backend/src/modules/*/__tests__/*.ts | BAJO | Solo tests |
+| frontend/src/features/catalogs/* | BAJO | Nuevo feature |
+| frontend/src/features/settings/* | BAJO | Nuevo feature |
+| database/seeds/*.sql | BAJO | Datos iniciales |

+### 7.2 Variables de Entorno Requeridas
+
+```env
+# Existentes (verificar)
+DATABASE_URL=
+JWT_SECRET=
+REDIS_URL=
+
+# Nuevas a agregar

+
+## 8. CONCLUSIONES
+
+### 8.1 Hallazgos Importantes
+
+1. **HR Schema YA EXISTE** (12-hr.sql) - El gap GAP-002 puede no ser valido
+2. **Redis config YA EXISTE** (config/redis.ts) - Facilita permission cache
+3. **Estructura FSD consistente** - Facilita crear nuevos features
+4. **Dependencias bien definidas** - Orden de implementacion claro
+
+### 8.2 Recomendaciones para Ejecucion
+
+1. **Verificar 12-hr.sql** antes de crear HR Schema
+2. **Verificar redis.ts** antes de implementar permission cache
+3. **Seguir estructura existente** para nuevos features
+4. **Respetar orden de DDL** en cualquier cambio de base de datos
+
+### 8.3 Siguiente Fase
+
+Proceder con **FASE 5: Refinamiento del Plan** incorporando estos hallazgos.

+### 8.1 Resumen
+
+| Aspecto | Estado |
+|---------|--------|
+| Cobertura de Gaps | 100% (20/20) |
+| Dependencias Mapeadas | 100% |
+| Orden Validado | OK |

+| Archivos Afectados | 75+ |
+
+### 8.2 Conclusion
+
+El plan de correcciones FASE-3 esta **VALIDADO** y puede proceder a FASE-5 (Refinamiento).
+
+**Recomendaciones:**
+1. Crear branch `feature/odoo-alignment` antes de cambios
+2. Ejecutar correcciones P0 primero (COR-001 a COR-006)
+3. Actualizar documentacion inmediatamente despues de cada DDL change
+4. Crear tests de regresion para cada correccion
+
+---
+
+## 9. Proximos Pasos (FASE 5)
+
+1. Refinar orden de ejecucion basado en capacidad
+2. Crear migration scripts detallados
+3. Definir tests de regresion
+4. Establecer rollback plan
