+## Arquitectura Clean
+
+```
+HTTP request
+   ▼
+presentation (Express controller)
+   ▼
+domain (use-case + DTO validator)
+   ▼
+data (repository impl / mock / cache)
+```
+
+### Reglas
+
+1. El **controller** solo recibe `req`, llama al use-case, responde JSON, maneja errores con `handleError()`.
+2. Los **use-cases** llevan toda la lógica de negocio.
+3. Los **DTOs** validan datos de entrada con métodos estáticos `static validate(data: unknown)`.
+4. Los **repositories** son interfaces en `domain/repositories/`; las implementaciones reales viven en `data/`.
+5. Los **errores** se manejan con `CustomError`: `badRequest`, `unauthorized`, `forbidden`, `notFound`, `conflict`, `internalServer`.
+6. JWT solo se maneja desde `JwtAdapter`. Bcrypt solo desde `BcryptAdapter`.
+7. Variables de entorno solo en `config/env.ts` (excepción: `.env`).
+
+---
+
+## Variables de entorno
+
+Archivo `.env` (no se sube al repo):
+
+```dotenv
+PORT=8080
+NODE_ENV=development
+
+DATABASE_URL=postgresql://user:password@localhost:5433/optihack
+POSTGRES_USER=user
+POSTGRES_PASSWORD=password
+POSTGRES_DB=optihack
+
+JWT_SEED=your_super_secret_jwt_seed_here_change_in_production
+JWT_EXPIRES_IN=7d
+
+BCRYPT_ROUNDS=10
+```
+
+| Variable | Default | Notas |
+|---|---|---|
+| `PORT` | `3000` | Aquí usamos `8080` porque otra app ocupa 3000 |
+| `DATABASE_URL` | — | Apunta a Postgres en 5433 (Docker mapping) |
+| `JWT_SEED` | — | Requerido. Cambiar en producción |
+| `JWT_EXPIRES_IN` | `7d` | Duración del token |
+| `BCRYPT_ROUNDS` | `10` | Costo del hash |
+| `POSTGRES_USER` / `POSTGRES_PASSWORD` / `POSTGRES_DB` | — | Usados por `docker-compose.yml` |
+
+---
+
+## Modelo de datos (Prisma)
+
+```prisma
+enum UserRole { USER ADMIN }
+
+model User {
+  id        Int      @id @default(autoincrement())
+  name      String
+  email     String   @unique
+  password  String
+  phone     String?  @unique
+  role      UserRole @default(USER)
+  isActive  Boolean  @default(true)
+  createdAt DateTime @default(now())
+  updatedAt DateTime @updatedAt
+  addresses Address[]
+  @@map("users")
+}
+
+model Address {
+  id           Int      @id @default(autoincrement())
+  userId       Int
+  label        String
+  street       String
+  neighborhood String?
+  postalCode   String?
+  latitude     Float?
+  longitude    Float?
+  isDefault    Boolean  @default(false)
+  createdAt    DateTime @default(now())
+  updatedAt    DateTime @updatedAt
+  user         User     @relation(fields: [userId], references: [id], onDelete: Cascade)
+  @@map("addresses")
+}
+```
+
+> En el MVP solo usamos `User`. `Address` está modelada pero los domicilios se guardan en mocks por ahora — se puede migrar sin tocar los controllers.
+
+---
+
+## Cómo correr
+
+### 1. Postgres con Docker
+
+```powershell
+docker compose up -d
+docker ps    # verifica que postgres:15.3 esté Up
+```
+
+### 2. Migraciones + cliente
+
+```powershell
+npm install
+npx prisma migrate deploy
+npx prisma generate
+```
+
+### 3. Dev
+
+```powershell
+npm run dev
+```
+
+Output esperado:
+
+```
+Database connected
+Seed admin: creado admin@test.com con password "admin123" (cambiar en producción)
+RouteSimulator started — tick every 30s
+Server is running on port 8080
+```
+
+### 4. Production build
+
+```powershell
+npm run build   # compila a dist/
+npm start       # corre node dist/app.js
+```
+
+### Scripts disponibles
+
+| Script | Hace |
+|---|---|
+| `npm run dev` | `tsx watch src/app.ts` — hot reload |
+| `npm run build` | `tsc` — emite a `dist/` |
+| `npm start` | `node dist/app.js` |
+
+---
+
+## Módulos
+
+### Auth (`/api/auth/*`)
+
+- **Registro**: hashea password con `BcryptAdapter`, crea con Prisma, agrega al mock de service con `routeId` default = `RUTA-01`. Siempre rol `USER`.
+- **Login**: compara password con bcrypt, genera JWT con `JwtAdapter.generate({ id, email })`. El login response incluye el `role` del DB.
+- **GetMe**: protegido con `AuthMiddleware.validate`, devuelve datos del user logueado.
+- Si un user legacy no estaba en el mock, el login lo agrega (idempotente con `upsertUser`).
+
+### Tracking (`/api/tracking/*`)
+
+- **POST `/gps-update`**: punto de entrada del simulador (o admin manual). Calcula ETA, evalúa notificaciones, escribe en `route-state` + `inbox`. Respeta cancelación.
+- **GET `/status`**: protegido. Devuelve la **visión de túnel** del user — solo su ruta, su ETA, sus notificaciones.
+- **POST `/reset-demo`**: limpia caches y estados en memoria sin reiniciar el server.
+
+### Direcciones (`/api/addresses/*`)
+
+- **GET `/colonias`**: catálogo público (mock).
+- **GET `/me`**: dirección actual del user.
+- **PUT `/me`**: cambia la colonia del user. Valida contra el catálogo; rechaza colonias inexistentes (cumple "validación de zona permitida" del reto).
+
+### Feedback (`/api/feedback/*`)
+
+- **POST**: envía feedback con tipo + mensaje + rating opcional. Tipos: `TRUCK_DID_NOT_PASS`, `RATING`, `SUGGESTION`, `OTHER`.
+- **GET `/me`**: feedbacks del user logueado (RBAC).
+
+### Admin (`/api/admin/*`)
+
+Todos requieren `AuthMiddleware.requireAdmin`.
+
+- **GET `/routes`**: lista todas las rutas con estado actual (status, currentPositionId, arrivalResult, cancelled).
+- **POST `/routes/:routeId/cancel`**: cancela la ruta. El simulador la pausa. Los users de esa ruta reciben notificación.
+- **POST `/routes/:routeId/resume`**: reanuda. Simulator vuelve a positionId 1 y se limpia el dedup cache.
+
+---
+
+## El simulador
+
+`data/simulation/route-simulator.ts`
+
+- Corre `setInterval` cada **30 segundos**
+- Solo simula `RUTA-01` por defecto (configurable en `SIMULATED_ROUTE_IDS`)
+- Cada tick: avanza el positionIndex de la ruta, dispara `ProcessGpsUpdateUseCase` con la posición correspondiente del mock
+- Cuando el ciclo se completa (positionIndex wrap a 0), limpia el dedup cache para que la siguiente vuelta vuelva a emitir notificaciones
+- Respeta el flag `cancelled` del estado de ruta: si está cancelada, no avanza
+- El admin puede llamar `resetPosition(routeId)` para volver el ciclo a 0
+
+```
+positionId 1 → (sin notif, salida del relleno)
+positionId 2 → ROUTE_START          "¡Ruta Iniciada!"
+positionId 3 → (sin notif, en camino)
+positionId 4 → TRUCK_PROXIMITY      "Camión Cercano"     (≈ 12 min de llegada)
+positionId 5 → TRUCK_ARRIVED        "El camión ya está aquí"  (ETA = 0, arrivalResult = ARRIVED)
+positionId 8 → ROUTE_COMPLETED      "Servicio Finalizado"
+wrap → cache cleared, loop back
+```
+
+---
+
+## Reglas de arquitectura
+
+Las reglas que mantenemos a lo largo del proyecto:
+
+1. **No lógica pesada en controllers.** Solo: recibir, validar, llamar use-case, responder.
+2. **Lógica de negocio en use-cases.**
+3. **Prisma solo en `data/repositories` o `data/postgres`.**
+4. **Use-cases dependen de interfaces** (`domain/repositories/*`), nunca de Prisma.
+5. **DTOs validan entrada** con `static validate()`.
+6. **Errores con `CustomError`**.
+7. **JWT solo via `JwtAdapter`. Bcrypt solo via `BcryptAdapter`**.
+8. **No regresar passwords en ninguna respuesta**.
+9. **Las rutas en `presentation`**. Middlewares en `presentation/middlewares`.
+10. **Variables de entorno solo en `config/env.ts`**.
+11. **No editar archivos generados** (`src/generated/prisma/*`).
+
+---
+
+## Troubleshooting
+
+| Síntoma | Causa | Fix |
+|---|---|---|
+| `Can't reach database server at localhost:5432` | DATABASE_URL apunta a 5432 pero Docker mapea 5433 | Cambiar puerto en `.env` a `5433` |
+| `Prisma client not found` | Cliente no generado | `npx prisma generate` |
+| Server arranca pero `/api/...` da 404 | Olvidaste registrar la ruta en `presentation/routes.ts` | Agregar `router.use('/api/X', XRoutes.routes)` |
+| Login devuelve 400 con error de Prisma | Tabla `users` no existe | `npx prisma migrate deploy` |
+| Admin tab no aparece en el front | Login devolvió role distinto a "ADMIN" | Verifica que el seed haya corrido (mira el log de arranque) |
+| Notificaciones repetidas no salen | Dedup cache | Esperar al wrap del simulador o llamar `POST /api/tracking/reset-demo` |
+
+---
+
+## Para extender
+
+- Añadir nuevo módulo X: copia la estructura de `feedback/` (DTO → repo → use-case → controller → route → registrar en `AppRoutes`)
+- Migrar un mock a DB real: cambia solo la **impl** en `data/`, las interfaces y use-cases no se tocan
+- Conectar Redis: nueva impl de `NotificationCacheRepository` y `RouteStateRepository`, cambia el `new InMemory...` por `new Redis...` en el controller
