+# Implementer evidence — CHECKOUT-RETURNTO
+
+## Resumen
+Haciendo que checkout redirecte al usuario a /checkout después de login/register en lugar de a /home.
+
+## Cambio
+
+### Login page
+- Añadido `useSearchParams` para leer `returnTo` de la URL.
+- Después de login exitoso, `router.push(returnTo)` en vez de `router.push('/')`.
+- Envuelto en `<Suspense>` porque `useSearchParams` requiere client boundary async.
+
+### Register page
+- Igual que login: lee `returnTo` de la URL.
+- Redirect post-register a `returnTo` en vez de a la página de "revisa tu correo".
+
+### CheckoutClient
+- Los enlaces de "Iniciar sesión" y "Crear cuenta" ahora apuntan a `/auth/login?returnTo=%2Fcheckout` y `/auth/register?returnTo=%2Fcheckout`.
+
+## Validación
+- `cd project/frontend && npm run build` ✅
+- `./scripts/verify.sh` ✅
+- `git diff --check` ✅

+## Resumen
+El endpoint checkout ahora devuelve errores del backend de forma legible usando `readErrorMessage` en vez de JSON crudo.
+
+## Cambio
+En `project/frontend/src/app/api/checkout/route.ts`, cuando la respuesta del backend no es OK, se usa `readErrorMessage` para extraer el mensaje legible del JSON del backend y envolverlo en `{ error: { code: 'CHECKOUT_FAILED', message } }`.

+# Arquitectura — CLUB-001 · Fase 1 Core backend
+
+## Análisis de arquitectura existente
+
+### Superficies del proyecto
+- **Backend API**: `project/src/app/build-app.ts` registra módulos Fastify desacoplados bajo `project/src/modules/*`.
+- **Frontend tienda**: `project/frontend/` consume la API vía rutas proxy Next.js.
+- **Admin panel**: `project/apps/admin/` usa endpoints backoffice/admin ya existentes.
+- **TPV/POS**: `project/apps/pos/` usa backend POS y órdenes como fuente de ventas.
+
+### Patrones que debemos reutilizar
+- **Módulo aislado por carpeta**: `api/`, `application/`, `domain/`, `infrastructure/`, `index.ts`.
+- **Rutas finas**: validación con `zod` + `parseJson`, errores con `AppError`, Swagger con `errorSchema`.
+- **Persistencia PostgreSQL**: migraciones `project/migrations/*.js` y repositorios `Pg*Repository`.
+- **Auth desacoplada por inyección**: módulos reciben `authenticate` desde `build-app.ts`; no importan internals de identity.
+- **Configuración editable**: `store_settings` ya actúa como KV-store para ajustes globales del negocio.
+- **Tests reales de integración**: `project/src/app/tests/*.itest.ts` recrean DB, aplican migraciones y prueban la app completa.
+
+## Decisiones técnicas para Fase 1
+
+### 1) Nuevo módulo `club`
+Se crea `project/src/modules/club/` con registro de rutas propio desde `build-app.ts`.
+
+### 2) Ledger como fuente de verdad
+- `club_transactions` será el **source of truth**.
+- `club_members.current_balance_cents` existirá solo como **cache/optimización**.
+- Cada escritura de ledger actualizará ambos dentro de la misma transacción.
+- El balance podrá reconstruirse con `SUM(balance_delta_cents)`.
+
+### 3) Configuración reutilizando `store_settings`
+No se crea un sistema nuevo de configuración.
+Se añaden claves:
+- `club_enabled`
+- `club_cashback_bps`
+- `club_allow_anonymous_members`
+- `club_allow_recovery_codes`
+- `club_minimum_redeem_cents`
+
+Esto mantiene consistencia con la arquitectura actual y simplifica futura UI admin.
+
+### 4) Dispositivo anónimo con token opaco hasheado
+- El backend genera `device_token` opaco.
+- Solo se persiste `device_token_hash` en `club_devices`.
+- El raw token se devuelve al cliente una sola vez en `POST /club/join`.
+- Las rutas de lectura de Club aceptarán el token mediante header/cookie para no acoplar la PWA todavía.
+
+### 5) Modelo preparado para fases futuras
+Aunque Fase 1 solo activa core backend, la migración deja base para próximas fases:
+- `club_members`
+- `club_devices`
+- `club_transactions`
+- `club_recovery_codes`
+- `club_rewards`
+- `club_campaigns`
+
+### 6) Cashback configurable, no hardcoded
+La lógica core leerá `club_cashback_bps` desde settings. El default inicial será **200 bps = 2%**.
+
+## Alcance funcional de CLUB-001
+
+### Sí entra en Fase 1
+- Crear socio anónimo.
+- Emitir token de dispositivo.
+- Consultar tarjeta/resumen del socio por token.
+- Consultar movimientos del ledger.
+- Configuración backend del Club.
+- Infraestructura de migraciones y tests.
+- Helper backend para registrar transacciones idempotentes sobre ledger.
+
+### No entra en Fase 1
+- PWA visual `/club/*`.
+- QR visual y endpoint TPV de identificación.
+- Recovery codes funcionales.
+- Vinculación a cuenta de usuario.
+- Admin UI.
+- Integración TPV completa de earn/redeem/refund.
+
+## Esquema inicial propuesto
+
+### `club_members`
+- `id uuid pk`
+- `user_id uuid null -> identity_users(id)`
+- `member_code text unique`
+- `status text` (`active|blocked|merged`)
+- `tier_code text default 'base'`
+- `current_balance_cents integer default 0`
+- `created_at`, `updated_at`
+
+### `club_devices`
+- `id uuid pk`
+- `member_id uuid fk -> club_members(id)`
+- `device_token_hash text unique`
+- `last_used_at timestamptz`
+- `created_at timestamptz`
+- `revoked_at timestamptz null`
+
+### `club_transactions`
+- `id uuid pk`
+- `member_id uuid fk -> club_members(id)`
+- `sale_id uuid null -> orders_orders(id)`
+- `store_id uuid null -> pos_stores(id)`
+- `type text` (`earn|redeem|refund|bonus|adjustment`)
+- `amount_cents integer`
+- `balance_delta_cents integer`
+- `idempotency_key text unique null`
+- `metadata jsonb not null default '{}'`
+- `created_at`
+
+### `club_recovery_codes`
+- Tabla preparada para Fase 4.
+- Guardará hash(es) del código, no plaintext.
+
+### `club_rewards`, `club_campaigns`
+- Tablas scaffold para evolución posterior sin activar motor complejo aún.
+
+## Endpoints backend de Fase 1
+
+### Públicos / cliente Club
+- `GET /club/config`
+  - Devuelve flags públicos del módulo.
+- `POST /club/join`
+  - Crea socio anónimo + device token.
+- `GET /club/me`
+  - Resuelve socio por device token.
+- `GET /club/movements`
+  - Lista movimientos del socio actual.
+
+### Admin / configuración
+- `GET /admin/club/settings`
+- `PATCH /admin/club/settings`
+
+### Aplicación interna
+- Servicio backend para registrar ledger idempotente y recalcular balance.
+- Se deja listo para ser usado por TPV en CLUB-003.
+
+## Validaciones clave
+- Rechazar `join` si `club_enabled=false` o `club_allow_anonymous_members=false`.
+- No aceptar tokens sin hash coincidente o revocados.
+- `member_code` único y corto, formato `MDV-XXXXXXXX`.
+- `type` del ledger restringido por CHECK.
+- `current_balance_cents` nunca por debajo de 0 en operaciones que no lo permitan.
+- `idempotency_key` único para evitar dobles registros.
+
+## Estrategia de tests
+- **Unit tests** para helpers de token/member code/config parsing.
+- **Boundary test** para evitar imports indebidos del módulo.
+- **Integration test real PostgreSQL** para:
+  - migraciones del Club
+  - `POST /club/join`
+  - `GET /club/me`
+  - `GET /club/movements`
+  - `GET/PATCH /admin/club/settings`
+  - escritura idempotente de ledger
+
+## Riesgos / deuda controlada
+- La PWA aún no existe; por eso Fase 1 devolverá el `deviceToken` al cliente y además dejará la ruta preparada para header/cookie.
+- El QR opaco persistente se implementará en la fase TPV/PWA, sin bloquear el core del ledger.
+- Recovery codes se dejan modelados pero no activados todavía para evitar complejidad prematura.

+# CLUB-001 — Documentation notes
+
+## New backend endpoints
+- `GET /club/config`
+- `POST /club/join`
+- `GET /club/me`
+- `GET /club/movements`
+- `GET /admin/club/settings`
+- `PATCH /admin/club/settings`
+
+## Contract notes
+- Anonymous Club identity is device-based for now.
+- Client receives the raw `deviceToken` once; database stores only `device_token_hash`.
+- The backend also persists the token in cookie `mdv_club` and accepts it again via cookie or `x-club-device-token` header.
+- `club_transactions` is the source of truth; `club_members.current_balance_cents` is a transactional cache.
+- Cashback is configurable through `store_settings` (`club_cashback_bps`) instead of hardcoded constants.
+
+## Scope boundary
+- CLUB-001 ships backend foundations only.
+- PWA screens, digital card UI, TPV integration, recovery flow and account linking remain for later CLUB phases.

+# Implementer evidence — CLUB-001
+
+## Resumen
+Implementé la **Fase 1 — Core backend** del nuevo módulo **Club de Clientes**.
+
+## Qué se creó
+
+### 1) Nuevo módulo backend `club`
+Archivos nuevos en `project/src/modules/club/`:
+- `api/club.routes.ts`
+- `application/club-service.ts`
+- `domain/club.ts`
+- `domain/errors.ts`
+- `domain/ports.ts`
+- `infrastructure/device-token.ts`
+- `infrastructure/member-code.ts`
+- `infrastructure/pg-club-repository.ts`
+- `index.ts`
+- `tests/token-and-code.test.ts`
+- `tests/boundary.test.ts`
+
+### 2) Migración core del Club
+- Nueva migración: `project/migrations/066_club_core.js`
+- Crea tablas:
+  - `club_members`
+  - `club_devices`
+  - `club_transactions`
+  - `club_recovery_codes`
+  - `club_rewards`
+  - `club_campaigns`
+- Añade seeds en `store_settings` para:
+  - `club_enabled`
+  - `club_cashback_bps`
+  - `club_allow_anonymous_members`
+  - `club_allow_recovery_codes`
+  - `club_minimum_redeem_cents`
+
+### 3) Endpoints backend de Fase 1
+- `GET /club/config`
+- `POST /club/join`
+- `GET /club/me`
+- `GET /club/movements`
+- `GET /admin/club/settings`
+- `PATCH /admin/club/settings`
+
+### 4) Comportamiento implementado
+- Alta anónima de socio Club.
+- Generación de `deviceToken` opaco.
+- Persistencia solo del `device_token_hash`.
+- Reutilización del socio actual si el dispositivo ya tenía token válido.
+- `memberCode` corto formato `MDV-XXXXXXXX`.
+- Ledger `club_transactions` como fuente de verdad.
+- `current_balance_cents` como cache transaccional.
+- Registro de transacciones idempotentes mediante `idempotencyKey`.
+- Configuración Club reutilizando `store_settings`.
+
+### 5) Wiring en la app
+- Registré el módulo en `project/src/app/build-app.ts`.
+
+## Tests añadidos
+- `project/src/modules/club/tests/token-and-code.test.ts`
+- `project/src/modules/club/tests/boundary.test.ts`
+- `project/src/app/tests/club.itest.ts`
+
+## Fixes necesarios para poder ejecutar itest reales
+Las itest reales del proyecto estaban bloqueadas por migraciones previas mal definidas con `pgm.addColumn(...)`.
+Corregí:
+- `project/migrations/057_product_variant_weight_and_expiry.js`
+- `project/migrations/058_identity_email_confirmation.js`
+
+Esto no cambia la intención funcional de esas migraciones; corrige únicamente su forma para que node-pg-migrate pueda aplicarlas.
+
+## Validación ejecutada
+- `./scripts/verify.sh` ✅
+- `cd project && npm run typecheck` ✅
+- `cd project && npm run build` ✅
+- `cd project && npx vitest run src/modules/club/tests/token-and-code.test.ts src/modules/club/tests/boundary.test.ts` ✅
+- `cd project && TEST_DATABASE_URL=postgres://mdv:mdv_dev_only@localhost:5432/mercadodevida_test npx vitest run src/app/tests/club.itest.ts --no-file-parallelism` ✅
+- `git diff --check` ✅
+
+## Decisiones técnicas relevantes
+- Reutilicé `store_settings` para configuración del Club en vez de crear otro subsistema.
+- El token de dispositivo sigue el patrón de sesiones existente: token opaco en cliente, hash SHA-256 en BD.
+- El módulo ya queda preparado para fases posteriores (PWA, TPV, recovery, linking, admin UI) sin introducirlas todavía.
+
+## Deuda / siguiente paso
+- Fase 2 debería construir la PWA `/club/*` consumiendo estos endpoints y mostrando la tarjeta digital.
+- `npm run lint:boundaries` sigue fallando por violaciones **preexistentes y ajenas** en módulos `pos` y `security`; no introducidas por CLUB-001.

+# Arquitectura — CLUB-002 · PWA Club
+
+## Objetivo
+Construir la primera experiencia frontend del Club sobre el backend ya entregado en CLUB-001:
+- alta/join del Club
+- tarjeta digital móvil
+- shell instalable tipo PWA
+
+## Análisis del frontend actual
+- La tienda usa Next App Router en `project/frontend/src/app`.
+- No existe manifiesto PWA ni rutas `/club/*` todavía.
+- Los flujos autenticados usan proxies Next.js (`/api/auth/*`) para preservar cookies same-origin.
+- CLUB-001 ya expone backend suficiente para esta fase:
+  - `GET /club/config`
+  - `POST /club/join`
+  - `GET /club/me`
+  - `GET /club/movements`
+
+## Diseño propuesto
+
+### 1) Proxy Next dedicado para Club
+Añadir `project/frontend/src/app/api/club/[...path]/route.ts`.
+
+Motivo:
+- preservar la cookie `mdv_club` como same-origin
+- reenviar `set-cookie` del backend en `POST /club/join`
+- evitar que componentes cliente hablen directo con `NEXT_PUBLIC_API_URL`
+
+### 2) Rutas frontend Club
+Crear páginas:
+- `/club` → landing/resumen del Club
+- `/club/join` → alta anónima o acceso al card si ya existe identidad Club
+- `/club/card` → tarjeta digital con member code, saldo y últimos movimientos
+
+### 3) Shell móvil instalable
+Añadir:
+- `app/manifest.ts`
+- iconos PWA a partir del branding existente
+- metadatos PWA en `app/layout.tsx` (`themeColor`, `appleWebApp`, manifest)
+- CTA de instalación desde cliente (`beforeinstallprompt`) en la superficie Club
+
+### 4) Estado de Club en cliente
+No crear aún un provider global complejo.
+En CLUB-002 basta con fetch puntual desde páginas/componentes Club:
+- `GET /api/club/config`
+- `POST /api/club/join`
+- `GET /api/club/me`
+- `GET /api/club/movements`
+
+Esto minimiza acoplamiento y deja abierta una futura extracción a `ClubContext` si la PWA crece.
+
+### 5) Tarjeta digital
+La card mostrará:

+- `/club`
+- `/club/join`
+- `/club/card`
+- `/manifest.webmanifest`
+
+## New same-origin proxy
+- `GET/POST/PATCH /api/club/[...path]`
+- Forwards Club requests to backend `/club/*`
+- Preserves incoming cookies and forwards backend `set-cookie`
+
+## User-facing behavior
+- Customers can activate an anonymous Club identity from the storefront without a separate login flow.
+- After join, the browser keeps the `mdv_club` cookie and the Club card can be reopened later from the same device.
+- The Club card shows member code, current balance and recent ledger movements.
+- The storefront now exposes install metadata for a standalone Club PWA shell.
+
+## Scope reminder
+- CLUB-002 is frontend/PWA only.
+- TPV scan semantics, recoveries and account linking stay in later Club phases.

+# Implementer evidence — CLUB-002
+
+## Resumen
+Implementé la primera superficie frontend/PWA del Club sobre el backend de CLUB-001.
+
+## Qué se añadió
+
+### 1) Proxy Next.js para Club
+- `project/frontend/src/app/api/club/[...path]/route.ts`
+
+Función:
+- reenviar `GET/POST/PATCH` al backend
+- propagar cookies entrantes
+- reenviar `set-cookie` del backend para conservar `mdv_club` same-origin
+
+### 2) Rutas frontend del Club
+- `project/frontend/src/app/club/page.tsx`
+- `project/frontend/src/app/club/join/page.tsx`
+- `project/frontend/src/app/club/card/page.tsx`
+- `project/frontend/src/components/club/ClubExperience.tsx`
+
+Comportamiento:
+- landing Club
+- alta anónima desde `POST /api/club/join`
+- tarjeta digital con `memberCode`, saldo y movimientos recientes
+- CTA para abrir la tarjeta cuando ya existe identidad Club en el dispositivo
+- bloque de instalación PWA usando `beforeinstallprompt`
+
+### 3) Manifest e iconos PWA
+- `project/frontend/src/app/manifest.ts`
+- `project/frontend/public/images/club-icon-192.png`
+- `project/frontend/public/images/club-icon-512.png`
+
+Además:
+- `project/frontend/src/app/layout.tsx` ahora declara manifest + metadata Apple Web App + viewport themeColor.
+
+### 4) Descubribilidad en storefront
+- enlace `Club` añadido en header y footer.
+
+## Decisiones de implementación
+- Reutilicé un único componente cliente `ClubExperience` para `/club`, `/club/join` y `/club/card`.
+- El frontend consume el backend Club vía proxy Next same-origin para que la cookie `mdv_club` quede gestionada correctamente por el navegador.
+- La tarjeta muestra una credencial visual móvil basada en `memberCode` y deja el contrato final de lectura en caja para CLUB-003, como estaba previsto en la fase TPV.
+
+## Validación ejecutada
+- `cd project/frontend && npm run build` ✅
+- `./scripts/verify.sh` ✅
+- `git diff --check` ✅
+
+## Riesgos / siguiente paso
+- CLUB-003 debe cerrar el contrato exacto de identificación en TPV/caja para usar la tarjeta digital también en escaneo/lectura operativa.
+- Conviene hacer smoke manual real en navegador/móvil para comprobar el prompt de instalación y la persistencia de `mdv_club` después de `POST /club/join`.

+# 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.

+# Architect — CLUB-004
+
+## Objetivo
+Permitir que un socio anónimo recupere su membresía en un dispositivo nuevo usando códigos de recuperación.
+
+## Diseño
+
+### Flujo
+1. **Alta**: al unirse al Club se generan 3 códigos (mostrados una sola vez).
+2. **Generar más**: `POST /club/recovery-codes/generate` (autenticado con device token o cuenta).
+3. **Listar**: `GET /club/recovery-codes` devuelve códigos activos (fingerprints, nunca plaintext).
+4. **Recuperar**: `POST /club/recover` acepta `{ code, newDeviceToken }` → consume código + vincula nuevo dispositivo.
+
+### Formato de código
+`XXXX-XXXX-XXXX-XXXX-XXXX-XXXX` (6 grupos de 4 chars alfanuméricos, sin I,O,0,1 para legibilidad).
+~44 bits de entropía (~10⁹⁶ combinaciones).
+
+### Almacenamiento
+- `code_hash = SHA-256(plaintext)` — para verificación
+- `code_fingerprint = SHA-256(UPPER(plaintext))[0:16]` — para lookups rápidos y dedup
+- `expires_at = now() + 30 días`
+- `used_at = NULL` initially
+
+### Seguridad
+- Código hasheado, nunca se guarda plaintext
+- `FOR UPDATE` en la misma transacción para evitar race conditions
+- Valida que no esté usado ni caducado antes de vincular
+
+### Endpoints nuevos
+| Método | Ruta | Auth | Descripción |
+|--------|------|------|-------------|
+| POST | `/club/recovery-codes/generate` | device token o sesión | Generar códigos |
+| GET | `/club/recovery-codes` | device token o sesión | Listar códigos activos |
+| POST | `/club/recover` | ninguno (código + token) | Recuperar con código |

+## Endpoints added
+
+### POST /club/recovery-codes/generate
+Genera códigos de recuperación (3 por defecto, máximo 10).
+- **Auth**: device token cookie/header o sesión de usuario
+- **Body**: `{ count?: number }`
+- **Response**: `{ member, codes: string[], config }` — los códigos plaintext se muestran **una sola vez**
+
+### GET /club/recovery-codes
+Lista códigos activos (sin usar, no caducados).
+- **Auth**: device token o sesión
+- **Response**: `{ member, codes: [{ id, fingerprint, expiresAt, createdAt }] }`
+
+### POST /club/recover
+Recupera la membresía usando un código de recuperación.
+- **Auth**: ninguno (usa código + nuevo token)
+- **Body**: `{ code: string, newDeviceToken: string }`
+- **Response**: `{ member, deviceToken, config }`
+- El código se consume (no reutilizable)
+- El nuevo dispositivo se vincula al miembro

+# Architect — CLUB-005
+
+## Objetivo
+Vincular socios anónimos a cuentas registradas de usuario, restaurar la tarjeta automáticamente al login y manejar fusión segura de membresías.
+
+## Diseño
+
+### 1. Restauración automática de tarjeta al login
+El endpoint `GET /club/me` ya lo hace — comprueba `userId` primero, luego cae back a device token. No se necesita cambio.
+
+### 2. Vincular miembro anónimo a cuenta registrada (`PATCH /club/me`)
+- El frontend llama a este endpoint después de login/register cuando hay cookie `mdv_club`
+- Requiere sesión (autenticado)
+- Usa el device token de la cookie para encontrar el socio anónimo
+- Actualiza `user_id` del socio anónimo al userId de la sesión
+- Si el usuario ya tiene un socio vinculado → retorna `linked: false`, no sobreescribe
+
+### 3. Fusión de membresías (`POST /club/merge`)
+- Para cuando el usuario tiene un socio anónimo (device) Y un socio registrado (userId)
+- El socio registrado es el primario (se conserva)
+- El socio anónimo se marca como `merged`, su saldo se suma al primario
+- Los dispositivos del anónimo se transfieren al primario
+- Los recovery codes del anónimo expiran (no se transfieren)
+
+### Seguridad
+- `PATCH /club/me` requiere sesión — no se puede vincular sin estar autenticado
+- `POST /club/merge` requiere sesión y solo usa el socio del usuario autenticado como primario
+- La transacción de merge usa `FOR UPDATE` para evitar race conditions
+
+### Endpoints nuevos
+| Método | Ruta | Auth | Descripción |
+|--------|------|------|-------------|
+| PATCH | `/club/me` | sesión | Vincular miembro anónimo a cuenta |
+| POST | `/club/merge` | sesión | Fusionar miembro anónimo en el registrado |
