## Overview

Apptrazabilidadfolios is a warehouse-exit tracking web app; its README identifies product-output scanning as the core task. The visible runtime also includes role-checked login, session cleanup, and service-worker caching for offline-capable use. The HTML pages are present, but their contents were not sampled, so the scanner’s implementation and its data flow to any backend cannot be confirmed; those links are omitted.

Main entry points: [`js/login.js`](https://github.com/dev-cerezo/apptrazabilidadfolios/blob/main/js/login.js) (Login handler), [`sw.js`](https://github.com/dev-cerezo/apptrazabilidadfolios/blob/main/sw.js) (Service worker), [`login.html`](https://github.com/dev-cerezo/apptrazabilidadfolios/blob/main/login.html) (Login page), [`js/logout.js`](https://github.com/dev-cerezo/apptrazabilidadfolios/blob/main/js/logout.js) (Logout and timeout)

## Connections

- Warehouse user → Login page: opens
- Login page → Login handler: submits credentials
- Login handler → Authentication API: checks credentials
- Authentication API → Login handler: returns user roles
- Login handler → Local session: stores session
- Login handler → Exit scanning: redirects after login
- Warehouse user → Exit scanning: scans exits
- Warehouse user → Logout and timeout: ends session
- Logout and timeout → Local session: clears session
- App startup → Service worker: registers
- Service worker → Cache helpers: calls cache helpers
- Service worker → Browser caches: reads and writes
- Service worker → Web network: fetches requests
- Login handler → Web network: requests login API
