# VigilanzaTurni - Sistema Gestione Turni per Istituti di Vigilanza

## Overview
VigilanzaTurni is a professional 24/7 shift management system for security companies, designed to streamline operations and enhance efficiency. It supports multi-role authentication (Admin, Coordinator, Guard, Client) and multi-location operations, managing over 250 security personnel across different branches. Key capabilities include comprehensive guard and site management, 24/7 shift planning, a live operational dashboard with KPIs, reporting for worked hours, and a notification system. The project aims to provide a robust, scalable solution for security companies, improving operational control and resource allocation.

## User Preferences

## System Architecture

### Stack Tecnologico
- **Frontend**: React + TypeScript + Tailwind CSS + Shadcn UI
- **Backend**: Express.js + TypeScript
- **Database**: PostgreSQL (Neon) with Drizzle ORM
- **Autenticazione**: Replit Auth (OIDC)
- **State Management**: TanStack Query v5
- **Routing**: Wouter
- **Maps**: Leaflet + react-leaflet + OpenStreetMap tiles

### Design System
- **Font Principale**: Inter (sans-serif)
- **Font Monospace**: JetBrains Mono
- **Colori**: Primary Blue, Status Green, Orange, Red, Gray for various operational states.
- **Tema**: Dark mode by default, with light mode support.
- **Componenti**: Shadcn UI with an operational design.

### Database Schema
The database supports managing users, guards, certifications, sites, shifts, shift assignments, notifications, customers, and service types. It also includes tables for advanced scheduling constraints such as guard constraints, site preferences, contract parameters, training courses, holidays, and absences. Service types include specialized parameters like `fixedPostHours`, `patrolPassages`, `inspectionFrequency`, and `responseTimeMinutes`.

### Core Features
- **Multi-Sede Operational Planning**: Location-first approach for shift planning, filtering resources by selected branch.
- **Service Type Classification**: Classifies services as "fisso" (fixed posts) or "mobile" (patrols, inspections) to route sites to appropriate planning modules.
- **Planning Fissi**: Weekly planning grid for fixed posts, enabling shift creation with guard availability checks. Includes weekly shift duplication feature with confirmation dialog and automatic navigation.
- **Planning Mobile**: Guard-centric interface for mobile services, displaying guard availability and hours, with an interactive Leaflet map showing sites. Features include:
  - **Smart Site Assignment Indicators**: Sites already in patrol routes display "Assegnato a [Guard Name]" button with scroll-to functionality; unassigned sites show "Non assegnato" text
  - **Drag-and-Drop Reordering**: Interactive drag-and-drop using @dnd-kit library for patrol route stops with visual feedback and automatic sequenceOrder persistence
  - **Route Optimization**: OSRM API integration with TSP (Traveling Salesman Problem) nearest neighbor algorithm; displays total distance (km) and estimated travel time in dedicated dialog
  - **Patrol Sequence List View**: Daily view of planned patrol routes with stops visualization
  - **Duplication/Modification Dialog**: Copy routes to different dates or modify assigned guard
- **Customer Management**: Full CRUD operations for customer details and customer-centric reporting with CSV export.
- **Dashboard Operativa**: Live KPIs and real-time shift status.
- **Gestione Guardie**: Complete profiles with skill matrix, certification management, and badge numbers.
- **Gestione Siti/Commesse**: Sites are associated with service types, including schedule, contract management, and location assignment. Automatic geocoding is supported.
- **Pianificazione Turni**: 24/7 calendar, manual guard assignment, basic constraints, and shift statuses.
- **Advanced Planning**: Management of guard constraints, site preferences, contract parameters, training courses, holidays, and absences. Includes patrol route persistence and exclusivity constraints between fixed and mobile shifts.
- **Guard Planning Views**: Dedicated views for guards to see their fixed post shifts and mobile patrol routes.
- **Site Planning View**: Coordinators can view all guards assigned to a specific site over a week.
- **Shift Duplication Features**:
  - **Weekly Copy (Planning Fissi)**: POST /api/shift-assignments/copy-week endpoint duplicates all shifts and assignments from selected week to next week (+7 days) with atomic transaction. Frontend includes confirmation dialog with week details and success feedback.
  - **Patrol Sequence Duplication (Planning Mobili)**: POST /api/patrol-routes/duplicate endpoint with dual behavior: UPDATE when target date = source date (modifies guard), CREATE when different date (duplicates route with all stops). Frontend shows daily sequence list with duplication dialog (date picker defaulting to next day, guard selector pre-filled but changeable).
- **Guardie Settimanale**: Compact weekly schedule view showing all guards' assignments across the week in a grid format. Features include:
  - **Weekly Grid View**: Guard names in first column, 7 daily columns (Mon-Sun) with compact cell display
  - **Multi-Source Aggregation**: GET /api/weekly-guards-schedule endpoint aggregates fixed shifts, patrol routes, and absences by location and week
  - **Compact Cell Format**: Fixed posts show "Site Name HH:mm-HH:mm", mobile patrols show "Pattuglia HH:mm-HH:mm", absences show status (Ferie/Malattia/Permesso/Riposo)
  - **Read-Only Dialogs**: Clicking cells opens appropriate dialog (fixed shift details or mobile patrol info) with navigation links to Planning Fissi/Mobile for edits
  - **Location and Week Filters**: Dropdown for branch selection, week navigation with prev/next buttons displaying "Settimana dal DD MMM al DD MMM YYYY"

### User Roles
- **Admin**: Full access.
- **Coordinator**: Shift planning, guard assignment, operational site management, reporting.
- **Guard**: View assigned shifts, time-punching, notifications, personal profile.
- **Client**: View assigned sites, service reporting, KPIs.

### Critical Date/Timezone Handling
The system handles timezone conversions for shift times, converting Italy local time from the frontend to UTC for database storage, and back to Italy local time for display, accounting for DST.
