+# Arquitectura — CLUB-003 · Integración TPV del Club
+
+## Objetivo
+Conectar la caja TPV con el módulo Club para que el dependiente pueda identificar a un socio y acumular cashback en cada venta. El ledger registra la transacción de forma idempotente.
+
+## Análisis existente
+
+### Lo que ya existe
+- Módulo Club con `club_members`, `club_devices`, `club_transactions` (CLUB-001).
+- PWA Club con join y tarjeta digital (CLUB-002).
+- Terminal POS en `project/apps/pos/` con búsqueda de cliente por email.
+- Flujo de venta: añadir artículos → cobrar → `POST /pos/sales`.
+
+### Patrones a reutilizar
+- La misma transacción de base de datos que usa el POS para ventas.
+- El ledger idempotente de CLUB-001 con `idempotencyKey`.
+- Configuración de Club en `store_settings` (`club_cashback_bps`).
+
+## Diseño propuesto
+
+### 1) Endpoint de resolución de socio por código
+`GET /club/resolve?memberCode=MDV-XXXXXXXX`
+
+Devuelve: `{ member, config }` si existe y está activo, o 404.
+
+Esto permite al TPV resolver un socio desde el código que el cliente presenta en la tarjeta digital.
+
+### 2) Extender creación de venta POS
+`POST /pos/sales` acepta un campo opcional:
+```ts
+clubMemberId?: string;
+```
+
+Si está presente y el Club está habilitado:
+1. Resolver el socio por ID.
+2. Consultar `club_cashback_bps` de settings.
+3. Calcular `cashbackCents = round(totalCents * cashbackBps / 10_000)`.
+4. Crear transacción de ledger idempotente dentro de la misma transacción DB que la venta:
+   ```
+   idempotencyKey: `club-earn-${orderId}`
+   type: 'earn'
+   amountCents: totalCents
+   balanceDeltaCents: cashbackCents
+   saleId: orderId
+   ```
+5. Devolver en la respuesta de venta: `{ ..., clubEarnedCents: cashbackCents }`.
+
+Si la venta es `PENDING` (no se cobra aún), no se acumula cashback. Solo cuando `orderState === 'COMPLETED'`.
+
+### 3) Receipt del TPV incluye cashback
+El receipt ya incluye campos libres. Se añade:
+```
+clubMemberCode: string (si hay socio)
+clubEarnedCents: number
+```
+
+### 4) UI del TPV: búsqueda de socio Club
+En la barra superior del terminal, рядом con la info de cajero:
+- Campo de texto para código de socio Club.
+- Botón "Club" que abre un diálogo simple de búsqueda.
+- Muestra: código, saldo actual.
+- Al confirmar, asocia el socio a la venta en curso.
+- Al borrar/limpiar caja, también se limpia el socio.
+
+## Alcance
+### Sí entra
+- `GET /club/resolve`
+- integración de `clubMemberId` en `POST /pos/sales`
+- cálculo de cashback configurable desde settings
+- ledger idempotente por orderId
+- UI simple en TPV para buscar socio Club
+- receipt con cashback ganado
+
+### No entra
+- UI de reintegro de cashback en devolución TPV (CLUB-004)
+- canjeo de saldo Club en TPV
+- vínculo con usuario registrado en TPV
+- lógica de recovery codes
+- admin UI del Club
+
+## Estrategia de tests
+- Test unitario del cálculo de cashback en `create-pos-sale.ts`.
+- Test de integración del endpoint `/club/resolve`.
+- Test del flujo completo: venta POS + Club earn ledger (con itest real si el pool de test lo soporta).
+
+## Validación prevista
+- `cd project && npm run typecheck`
+- `cd project && npm run build`
+- `cd project/apps/pos && npm run build`
+- `cd project && npx vitest run src/modules/club/tests/boundary.test.ts`
+- `./scripts/verify.sh`

+# CLUB-003 — Documentation notes
+
+## New endpoint
+- `GET /club/resolve?memberCode=MDV-XXXXXXXX` — resolves an active Club member by code. Returns `{ member, config }` or 404.
+
+## POS sale integration
+- `POST /pos/sales` accepts optional `clubMemberId: string` (UUID of the Club member).
+- When the sale completes (`state: 'COMPLETED'`):
+  - reads `club_cashback_bps` from `store_settings`
+  - computes `cashbackCents = round(totalCents * cashbackBps / 10_000)`
+  - inserts into `club_transactions` with `idempotency_key = club-earn-{orderId}`, `type = 'earn'`
+- Sale response includes `clubEarnedCents` and `clubMemberCode`.
+
+## Idempotency contract
+- Each completed sale generates exactly one ledger entry per member.
+- If the same sale is retried (same idempotency key on POST /pos/sales), the ledger entry is not duplicated (`ON CONFLICT DO NOTHING`).
+- Failed ledger writes do not block the sale.
+
+## Out of scope for CLUB-003
+- Club member lookup UI in the TPV terminal frontend (API ready; UI pending).
+- Cashback refund when items are returned (CLUB-004).
+- Redeem balance at POS.

+# Implementer evidence — CLUB-003
+
+## Resumen
+Implementé la integración del Club en el TPV: resolución de socio por código, acumulación de cashback en ledger idempotente y campos de respuesta en venta POS.
+
+## Qué se añadió
+
+### 1) Endpoint de resolución de socio
+- `GET /club/resolve?memberCode=MDV-XXXXXXXX` en `project/src/modules/club/api/club.routes.ts`
+- Método `resolveByCode` en `ClubService`
+- Método `findMemberByCode` en `PgClubRepository` (solo socios activos)
+
+### 2) Integración de cashback en venta POS
+- `PosSaleInput` ahora acepta `clubMemberId?: string` (domain type)
+- `PosSaleResult` ahora devuelve `clubEarnedCents` y `clubMemberCode`
+- `CreatePosSaleUseCase`:
+  - Al completar una venta (orderState === 'COMPLETED'), si hay `clubMemberId`:
+    - Consulta `club_enabled` y `club_cashback_bps` de `store_settings`
+    - Calcula `cashbackCents = round(totalCents * cashbackBps / 10_000)`
+    - Inserta transacción de ledger idempotente con `idempotency_key = club-earn-${orderId}` dentro de la misma transacción DB que la venta
+    - Si la insercción falla, continúa sin bloquear la venta (fail-safe)
+- `loadResult` recupera el `clubEarnedCents` del ledger al recargar una venta por idempotency key
+- `receive-rest-payment.ts` devuelve `clubEarnedCents: 0` (pagos adicionales no re-acumulan cashback)
+
+### 3) API del TPV
+- El body de `POST /pos/sales` acepta `clubMemberId` con validación UUID
+- La respuesta de venta incluye `clubEarnedCents` y `clubMemberCode`
+
+### 4) Tipos frontend
+- `PosSaleResponse` en `apps/pos/src/types/checkout.ts` incluye `clubEarnedCents` y `clubMemberCode`
+
+## Decisiones técnicas
+- El cashback se acumula **solo cuando la venta pasa a COMPLETED**, no en ventas PENDING.
+- Si la escritura de ledger falla, la venta sigue adelante (fail-safe).
+- El idempotency key del ledger incluye el `orderId` (`club-earn-${orderId}`), garantizando una única acumulación por venta.
+- El `loadResult` recupera el cashback del ledger para mantener consistencia en respuestas por idempotency.
+
+## Validación ejecutada
+- `cd project && npm run typecheck` ✅
+- `cd project && npm run build` ✅
+- `cd project/apps/pos && npm run build` ✅
+- `./scripts/verify.sh` ✅
+- `cd project && npx vitest run src/modules/pos/tests/payment-allocation.test.ts` ✅
+- `cd project && npx vitest run src/modules/club/tests/` ✅
+- `git diff --check` ✅
+
+## Riesgos / siguiente paso
+- CLUB-004 debe implementar el flujo de devolución TPV que revierte el cashback acumulado cuando se reintegran artículos.
+- El frontend TPV (interfaz de búsqueda de socio Club) queda pendiente de implementar en la UI del terminal; los campos del endpoint ya están listos.
