# AeroFind v1.0.0 Stable: Technical Whitepaper & Project Overview

**Enterprise Ground Service & Logistics Intelligence**

---

## 01. EXECUTIVE FOUNDATION

### Mission Statement
AeroFind v1.0.0 is a professional middleware ecosystem designed to resolve the critical latency in airline baggage recovery and lost property management. By bridging legacy mainframe protocols (WorldTracer) with modern autonomous logistics (DPD/Haversine Routing), AeroFind transforms an operational bottleneck into a seamless, high-transparency service recovery experience.

### Stakeholder Accessibility
- **Interactive Demo Suite**: A zero-backend environment in `/demo` for immediate stakeholder evaluation, featuring functional staff, admin, and passenger portal mockups.
- **Anonymized Data Compliance**: All demonstration environments utilize non-sensitive, generic data profiles to ensure security and privacy during pitch sessions.

### Technical Stack
- **Production Core**: PHP 8 (Stable)
- **Database Layer**: MySQL with PDO (Type-Safe)
- **Security**: AES-256 Payload Encryption, CSRF Protection, and Session-Locked Internal Portals
- **Frontend**: TailwindCSS Design System with Inter/Outfit Typography
- **Reporting**: Automated PDF Generation via DomPDF
- **Demo Logic**: Client-side `demo.js` for full interaction simulation

## 02. LOGISTICS & RECOVERY INTELLIGENCE

### The BDO Routing Engine
The core of AeroFind's efficiency lies in its proprietary BDO (Baggage Delivery Order) Routing Engine. Unlike legacy systems that rely on manual courier assignment, AeroFind uses spherical geometry to calculate optimal recovery paths.

#### Technical Spotlight: Haversine Calculation
AeroFind computes the "Great Circle" distance between the report origin and the passenger's current delivery coordinate to identify the nearest logistics node.

**Formula Implementation:**
```php
function haversineDistance(float $lat1, float $lon1, float $lat2, float $lon2): float {
    $R = 6371.0; // Radius of Earth in km
    $dLat = deg2rad($lat2 - $lat1);
    $dLon = deg2rad($lon2 - $lon1);
    $a = sin($dLat / 2) ** 2 + cos(deg2rad($lat1)) * cos(deg2rad($lat2)) * sin($dLon / 2) ** 2;
    return $R * 2 * atan2(sqrt($a), sqrt(1 - $a));
}
```

### Automation Handshaking
- **AviationStack Integration**: Real-time flight telemetry for pirate report reconciliation.
- **DPD REST API**: Automated fulfillment triggering and parcel tracking label generation.
- **Cabin Recovery Module**: Dedicated search and matching logic for on-board lost items (wallets, devices, documents).

## 03. ENTERPRISE OPERATIONS & COMPLIANCE

### Operational Transparency
- **Audit Registry**: Every agent action, API call, and status change is logged in a centralized, time-stamped registry for high operational accountability.
- **Staff Command Deck**: A high-fidelity dashboard for operational agents featuring PIR queues, match metrics, and task management.
- **Real-Time Tracking Portal**: Tokenized passenger access to a live timeline of the recovery lifecycle.

### Data Governance (GDPR)
To remain compliant with EU Data Protection mandates, AeroFind implements a cron-driven auto-purge engine that scrubs PII (Personally Identifiable Information) according to strict retention profiles:
- **Baggage Data**: 90 Days
- **Cabin Property**: 180 Days
- **System Audit Logs**: 365 Days
