The prompt I run on my own pull requests before anyone else sees them

Review the diff below as a senior engineer who is tired and does not want to be paged at 3am because of it.

For each finding, give: file:line, severity (bug / risk / nit), a one-sentence explanation, and the smallest possible fix. Order by severity. Skip style comments unless they hide a bug.

Then answer three questions in one line each:

1. What input would make this code do the wrong thing?
2. What happens if the network call in the middle fails halfway?
3. What would I need to roll back if this ships and is wrong?

If you find nothing, say “nothing” — do not invent findings to look thorough.
