Split Proformas / Issued Invoices

Estado: historico / transicional.
No describe el runtime minimo vigente por si solo; la fuente operativa actual para proformas es la combinación de:

• docs/document-series/README.md
• docs/customer-invoices/proforma-series-contract.md
• docs/customer-invoices/proforma-create-contract.md
• docs/customer-invoices/proforma-tax-config.md
• docs/catalogs/payment-terms.md

Estado: diseno tecnico / fases 1A-1D + 2A-2B
Estado del backend: persistencia V2 activada; integracion con document-series activa para numeracion nueva; sin ejecucion confirmada de migracion DB

Objetivo

Preparar el esquema fisico para separar:

• customer_invoices -> proformas
• customer_invoices -> issued_invoices
• customer_invoice_items -> proforma_items
• customer_invoice_items -> issued_invoice_items
• customer_invoice_taxes -> proforma_taxes
• customer_invoice_taxes -> issued_invoice_taxes
• verifactu_records.invoice_id -> verifactu_records.issued_invoice_id

Decisiones de fase 1A

• proforma_reference es el identificador visible canonico de proforma.
• target_invoice_series_code sustituye la semantica legacy de series en proformas.
• document_series_id identifica la serie documental usada para numerar la proforma.
• proforma_number guarda el numero propio asignado a la proforma.
• target_invoice_series_code es opcional y solo puede apuntar a una serie de issued_invoice.
• una serie PF o cualquier otra serie de document_type = proforma nunca debe persistirse en target_invoice_series_code.
• si target_invoice_series_code queda NULL, la emision de la factura usara la serie default activa de issued_invoice.
• issued_invoices usa invoice_series_code, invoice_number, invoice_reference, invoice_date y source_proforma_id.
• proformas no guarda issued_invoice_id; la relacion se resuelve con issued_invoices.source_proforma_id.
• Los impuestos del esquema actual son por documento, no por linea: proforma_taxes y issued_invoice_taxes.
• payment_method y payment_term en issued_invoices son snapshot historico, no estado vivo de cobro.
• No hay doble escritura.
• Legacy queda congelado solo para validacion y rollback cuando se haga el cutover.

Estado de fase 1B

• Existen mappers Sequelize V2 sobre proformas, proforma_items, proforma_taxes.
• Existen mappers Sequelize V2 sobre issued_invoices, issued_invoice_items, issued_invoice_taxes.
• Existen repositorios Sequelize V2 listos para convivir con los repositorios legacy.
• El wiring activo legacy no se ha sustituido todavia.
• El dominio/application sigue arrastrando naming legacy en algunos contratos (series, invoiceNumber, linkedProformaId); la traduccion queda encapsulada en Infrastructure V2.
• Esta afirmación quedó obsoleta. El runtime actual ya soporta payment_term en Company, Customer, Proforma e Issued Invoice según docs/catalogs/payment-terms.md.

Estado de fase 1C

• El wiring activo del modulo usa persistencia V2 en los composition roots principales.
• buildV2ProformaPersistence(...) queda activo en:
  • modules/customer-invoices/src/api/infrastructure/proformas/di/proformas.di.ts
  • modules/customer-invoices/src/api/infrastructure/proformas/di/proforma-public-services.ts
• buildV2IssuedInvoicePersistence(...) queda activo en:
  • modules/customer-invoices/src/api/infrastructure/issued-invoices/di/issued-invoices.di.ts
  • modules/customer-invoices/src/api/infrastructure/issued-invoices/di/issued-invoice-public-services.ts
• La persistencia legacy no se borra, pero deja de ser la ruta operativa principal.
• La emision Proforma -> IssuedInvoice ahora encadena sobre V2:
  • lee proformas
  • crea issued_invoices
  • crea issued_invoice_items
  • crea issued_invoice_taxes
  • marca la proforma como issued
  • usa issued_invoices.source_proforma_id
• No hay doble escritura: cada composition root sigue instanciando una sola familia de repositorios.
• VerifactuRecord queda preparado para la ruta V2 mediante issued_invoice_id como relacion principal.
• La migracion/backfill real sigue pendiente. Si la BD real no tiene las tablas nuevas, el backend no podra arrancar correctamente con este wiring.

Estado de fase 1D

• Existen scripts SQL separados para desarrollo:
  • docs/customer-invoices/sql/dev-split-proformas-issued-invoices.sql
  • docs/customer-invoices/sql/validate-split-proformas-issued-invoices.sql
• El SQL de desarrollo es idempotente y conservador:
  • crea tablas V2 con CREATE TABLE IF NOT EXISTS
  • hace backfill con NOT EXISTS
  • no usa DROP, TRUNCATE ni DELETE
  • no sobrescribe filas ya migradas
  • no toca datos legacy salvo la columna transicional verifactu_records.issued_invoice_id
• Se documenta el orden de ejecucion en docs/customer-invoices/sql/README.md.
• En este workspace no se encontro una configuracion de BD de desarrollo inequivoca (.env* no presente en raiz del repo), por lo que no se ejecuto SQL real.
• Tampoco se hizo validacion funcional contra runtime real porque falta una BD de desarrollo confirmada y migrada para esta fase.

Dependencias compartidas y exclusivas

Compartidas entre legacy y V2

• contratos de Application (IProformaRepository, IIssuedInvoiceRepository)
• use cases, servicios de dominio y assemblers
• TransactionManager
• adaptadores legacy de InvoiceSeriesNumberAssigner para IssuedInvoice
• resolvers de catalogos
• servicios de documentos PDF/preview

Exclusivas de legacy

• CustomerInvoiceModel como storage real de Proforma e IssuedInvoice
• numerador de proformas sobre customer_invoices.invoice_number con is_proforma = true
• repositorios Sequelize legacy de customer_invoices
• CustomerInvoiceSeriesModel y SequelizeInvoiceSeriesRepository como wiring transicional no prioritario

Exclusivas de V2

• tablas proformas, proforma_items, proforma_taxes
• tablas issued_invoices, issued_invoice_items, issued_invoice_taxes
• numerador V2 de proformas sobre document-series, con snapshot en proformas.document_series_id, proforma_number y proforma_reference
• mappers y repositorios Sequelize V2

Regla operativa actual de series en proformas

La semantica operativa vigente ya no se mantiene en este documento historico.

Fuente canonica actual:

• docs/customer-invoices/proforma-series-contract.md
• docs/customer-invoices/proforma-create-contract.md
• docs/customer-invoices/proforma-tax-config.md

Este documento conserva solo el contexto de migracion, fases y SQL historico.

Estado Fase 2B

• customer-invoices ya no usa customer_invoice_series como fuente primaria para listar series activas ni para asignar numeracion nueva en issued_invoice y proforma
• /catalogs/invoice-series fue transicional y queda eliminado antes de produccion
• document-series queda como API canonica para listar series activas y asignar numeracion
• la DDL de proformas y la migracion/validacion SQL quedan documentadas, no ejecutadas
• la propagacion de branchId sigue pendiente porque el contexto de sucursal no llega todavia a los casos de uso activos

Estado Fase 2C

• se detecto un entorno de desarrollo en apps/server/.env.development
• produccion quedo descartada para ejecucion en esta fase
• no se ejecuto SQL real desde esta terminal por bloqueo operativo del cliente de BD local
• la DDL de proformas se endurecio para compatibilidad MariaDB/MySQL mediante information_schema y SQL dinamico
• la validacion funcional y la prueba de concurrencia quedaron documentadas para ejecucion manual sobre la BD de desarrollo segura

Estado Fase 2D

• el contrato publico de proformas ya soporta target_invoice_series_code en create y update
• la semantica detallada del alias legacy series se consolido despues en proforma-series-contract.md
• el cliente interno del modulo ya emite target_invoice_series_code en requests nuevos

Estado Fase 2E

• create separa proforma_series_code de target_invoice_series_code
• las reglas operativas exactas se consolidaron despues en proforma-series-contract.md
• la UI nueva de proformas ya envia proforma_series_code y target_invoice_series_code

Estado Fase 2F

• create de proforma se consolida como creacion de cabecera/documento inicial
• la semantica funcional exacta de create se consolido despues en proforma-create-contract.md

Estado Fase 2G

• DELETE /proformas/:proforma_id vuelve a estar operativo sobre persistencia V2
• el borrado es logico mediante deleted_at
• el archivado es logico mediante archived_at
• el listado V2 de proformas usa Criteria filters[] para archived_at y status
• GET /proformas/:id permite abrir proformas archivadas
• las reglas funcionales exactas de borrado y numeracion se consolidaron despues en proforma-series-contract.md
• la validacion de borrado comprueba tambien linked_invoice_id y issued_invoices.source_proforma_id
• la numeracion de document-series no se reutiliza ni se decrementa tras un borrado

Rollback recomendado

• no aplicar nada en produccion en esta fase
• si en desarrollo se ejecuta la DDL/migracion y hay que revertir, hacerlo con backup previo o clon de desarrollo, nunca con borrado destructivo improvisado
• conservar customer_invoice_series solo como legado historico hasta ejecutar la limpieza operativa documentada

• no integracion Verifactu funcional nueva
• no cambios en controllers, rutas o DTOs publicos

No incluido en fase 1D

• no ejecucion en produccion
• no borrado de tablas legacy
• no eliminacion de modelos/repositorios legacy
• no integracion Verifacti funcional
• no dominio de cobros
• no doble escritura

Resultado de validacion tecnica fase 1D

• tsc modulo customer-invoices: esperado ejecutar en esta fase
• biome lint sobre src/api/infrastructure y docs/customer-invoices: esperado ejecutar en esta fase
• tsc raiz: esperado ejecutar en esta fase
• Validacion SQL real: no ejecutada por falta de entorno de desarrollo inequivoco
• Validacion runtime real contra BD migrada: no ejecutada por la misma razon

Siguiente fase recomendada

• confirmar .env/credenciales de una BD de desarrollo segura
• ejecutar solo los runbooks SQL que sigan siendo necesarios para el entorno real afectado
• levantar el backend contra esa BD y validar create, update, get, list e issue proforma
• validar numeracion de proformas V2 y asignacion de serie/numero de factura emitida
• revisar la ruta VerifactuRecord -> issued_invoice_id ya con persistencia V2 activa

Nota document-series

customer-invoices ya migró funcionalmente desde CustomerInvoiceSeriesModel hacia document-series. Como nota histórica de Fase 2A:

• issued_invoice ya asigna numeración nueva mediante document-series
• proforma ya asigna referencia nueva mediante document-series
• la UI debe consumir GET /document-series filtrando por document_type
• CustomerInvoiceSeriesModel deja de existir como modelo runtime activo

Fase 2B no incluida

• no ejecucion de SQL en una BD real
• no borrado de tablas/modelos/repositorios legacy
• no propagacion completa de branchId
• no cambios de frontend salvo compatibilidad ya existente
• no nueva infraestructura de tests automatizados para estos modulos
