Interview Prompt
The alerting pipeline needs to flag metric readings that deviate sharply from recent history, without hard-coding thresholds for every service. Write a function that scans a time series and reports any value that strays too far from the rolling average of the preceding data points.

- Ask clarifying questions to the AI interviewer
