The Scenario

Your LLM provider started timing out 5% of requests. You didn't notice for 3 days because you only alert if >50% of requests fail. Your users are churning.

The Goal

Implement a Sliding Window Error Rate:

1. Track the last 100 requests.
2. Calculate error_rate = errors / total.
3. If error_rate > 0.05 (5%), return True (Trigger Alert).

Requirements:

• Use a list to store request status (1=Error, 0=Success).
• Keep only the last 100 requests.
• Return True if average > 0.05.
