After API credentials leaked on July 1 of 2025, every owner who held a token in `api_tokens` that was valid that day must rotate. The security team wants those owners listed.

Summary

One specific day. Which tokens were still alive?

How This Interview Works

1. Read the vague prompt (just like a real interview)
2. Ask clarifying questions to the AI interviewer
3. Write and run your SQL against a real database
4. Answer the interviewer's follow-up questions, then get a hire or no-hire decision
