Interview Prompt
We're auditing which API tokens are still carrying live traffic. Surface the 5 busiest tokens that haven't expired, where a token counts as unexpired if it has no expiration date set or its expiration is still in the future, and show each token with its issuance date.
Summary
The busiest keys are the ones that never had a deadline.
