# 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 |

# CLUB-004 — Documentation
## 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

# Implementer — CLUB-004
## Resumen
Implementados códigos de recuperación del Club: generación, listado y recuperación con nuevo dispositivo.
## Archivos modificados/creados
- `src/modules/club/domain/club.ts` — tipos `ClubRecoveryCode`, `GenerateRecoveryCodesResult`, `RecoverByCodeResult`
- `src/modules/club/domain/errors.ts` — `ClubRecoveryCodeInvalidError`, `ClubRecoveryCodesDisabledError`
- `src/modules/club/domain/ports.ts` — порты: `generateRecoveryCodes`, `listActiveRecoveryCodes`, `consumeRecoveryCode`
- `src/modules/club/infrastructure/pg-club-repository.ts` — implementación + `generateRecoveryCode()` helper
- `src/modules/club/application/club-service.ts` — `generateRecoveryCodes()`, `listRecoveryCodes()`, `recoverByCode()`
- `src/modules/club/api/club.routes.ts` — 3 endpoints nuevos + mapeo de errores
- `migrations/067_club_recovery_code_index.js` — índice en `code_fingerprint`
## Validación
- `cd project && npm run typecheck` ✅
- `cd project && npm run build` ✅
- `npx vitest run src/modules/club/tests/` ✅ (4 tests pass)
- `git diff --check` ✅
- `./scripts/verify.sh` ✅
