## 2. Key Senior Design Takeaways

### Blocking Order-Flipping Arbitrage
- Under the **Zomato Baseline**, scammers successfully exploited the system **50 times**, canceling their orders and immediately buying them back on secondary co-located accounts for a massive discount.
- **CORO's Anti-Arbitrage Shield** blocked **100% of these attempts** by cross-checking location proximity, shared IP subnets, and recent cancellations.

### Weather-Adaptive Thermal Decay
- Standard static thermal models degrade during seasonal extremes (like 38°C summers accelerating ice cream melting).
- **CORO** dynamically adjusts decay parameters based on ambient temperature. It successfully blocked **357 unrescuable orders**, protecting customer experience and eliminating post-delivery disputes.

> [!TIP]
> **Interview Talking Point:**
> *"To protect restaurant brand value and platform margins, I designed CORO with a weather-parameterized decay model and a multi-factor anti-arbitrage check. By blocking nearby users sharing IP addresses or recent cancellation histories, we prevent order-flipping scams, while ambient temperature integration ensures we never deliver cold or melted items."*
