What if · the follow-ups in this answer

The answer works through 4 follow-ups like an interviewer would

A plan-change tool timed out. The audit trail contains an allowed decision and a hash of a document, but no retained document version and no provider result.

  1. Can the hash recreate the missing document?
  2. Does the timeout establish that the plan was unchanged?
  3. Would signing every log prove complete and truthful records?
  4. How would you test the audit design?

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.
