What if · the follow-ups in this answer

The answer works through 5 follow-ups like an interviewer would

A document agent has queued an export and exchanged its original token for a connector token. The owner withdraws access while a worker is running. The team must explain what stopped and what may already have happened.

  1. What if revoking the original token leaves the connector token active?
  2. What if every call checks a 30-second cached active result?
  3. What if the worker passes authorization just before withdrawal?
  4. What if the agent is about to return a summary from retrieved data?
  5. What evidence would support the stated stop-time objective?

Each rung has a nudge, a model answer, the principle that carries over and the weak answer to avoid. Premium opens every answer and ladder.
