+## Plan de Limpieza
+
+### Fase 1: Eliminar Archivos de Analisis Historico
+
+Estos archivos fueron utiles para el analisis pero no deben permanecer:
+
+```
+MOVER A: docs/99-historico/ (o eliminar)
+- docs/90-transversal/ANALISIS-ARQUITECTONICO-IMPLEMENTACION.md
+- docs/90-transversal/PLAN-RESOLUCION-GAPS.md (parcial)
+```
+
+### Fase 2: Reescribir Archivos de Herencia
+
+```
+REESCRIBIR COMPLETAMENTE:
+- database/HERENCIA-ERP-CORE.md → ARQUITECTURA-DATABASE.md
+- orchestration/00-guidelines/HERENCIA-ERP-CORE.md → ELIMINAR
+- orchestration/00-guidelines/HERENCIA-SPECS-ERP-CORE.md → ELIMINAR
+- orchestration/00-guidelines/HERENCIA-DIRECTIVAS.md → DIRECTIVAS-PROYECTO.md
+```
+
+### Fase 3: Editar Referencias en Documentacion
+
+```
+EDITAR:
+- README.md: Eliminar "Extiende erp-core"
+- PROJECT-STATUS.md: Eliminar metricas Odoo/erp-core
+- docs/00-vision-general/VISION.md: Reescribir seccion herencia
+- docs/08-epicas/README.md: Eliminar tabla MGN
+- docs/02-definicion-modulos/*/README.md: Eliminar "Extiende MGN-*"
+```
+
+### Fase 4: Limpiar Comentarios SQL
+
+```sql
+-- ELIMINAR comentarios como:
+-- "NOTA: Los schemas auth, core, inventory se heredan de erp-core"
+-- "Referencia a auth.tenants de erp-core"
+-- "Implementa patron mail.thread de Odoo adaptado"
+```
+
+### Fase 5: Corregir Rutas Absolutas
+
+```yaml
+# CAMBIAR de:
+/home/isem/workspace/projects/erp-suite/apps/verticales/mecanicas-diesel
+
+# A (rutas relativas):
+./  (o eliminar rutas absolutas)
+```
+
+### Fase 6: Actualizar Inventarios
+
+```
+EDITAR:
+- orchestration/inventarios/MASTER_INVENTORY.yml
+- orchestration/inventarios/DATABASE_INVENTORY.yml
+- orchestration/inventarios/BACKEND_INVENTORY.yml
+- orchestration/inventarios/FRONTEND_INVENTORY.yml
+```
+
+---
+
+## Configuracion de Puerto Compartido: PostgreSQL
+
+El unico recurso compartido entre proyectos del workspace es PostgreSQL:
+
+```yaml
+PostgreSQL:
+  puerto: 5432
+  compartido: true
+  aislamiento:
+    - Cada proyecto tiene su propia BASE DE DATOS
+    - Cada proyecto tiene sus propios USUARIOS
+    - NO comparten schemas ni datos
+    - Multi-tenancy interno por tenant_id
+
+Ejemplo:
+  proyecto_1:
+    database: mecanicas_diesel_db
+    user: mecanicas_user
+  proyecto_2:
+    database: construccion_db
+    user: construccion_user
+```
+
+**Protocolo DEVENV:**
+- Puerto 5432 es el unico compartido (PostgreSQL server)
+- Todos los demas puertos (backend, frontend, etc.) son UNICOS por proyecto
+- SIEMPRE consultar DEVENV antes de asignar nuevos puertos
+
+---
+
+## Proximos Pasos
+
+1. **[PENDIENTE]** Ejecutar limpieza de referencias
+2. **[PENDIENTE]** Validar que el proyecto sea completamente standalone
+3. **[PENDIENTE]** Actualizar PROJECT-STATUS.md despues de limpieza
+4. **[LISTO]** Iniciar desarrollo con TECH-LEADER
+
+---
+
+## Notas Importantes
+
+### El Proyecto ES Independiente
+
+Aunque hay muchas referencias a erp-core y Odoo en la documentacion, el codigo DDL y la estructura del proyecto **YA SON INDEPENDIENTES**:
+
+- Los schemas son propios (`service_management`, `parts_management`, etc.)
+- No hay FKs reales a erp-core
+- Las funciones RLS son propias
+- Los seeds son propios
+
+Las referencias son **documentales** (para trazabilidad del analisis), no **funcionales**.
+
+### Recomendacion
+
+Antes de limpiar, considerar si vale la pena mantener un archivo `docs/99-historico/ORIGEN-PATRONES.md` que documente de donde vinieron los patrones sin que sea parte activa del proyecto.
