It would take the same amount of time to finish with or without turns (concurrency) and you would have done the same amount of work.

When `authenticate_user` is called with a username that doesn't exist in the database, we still run `verify_password` against a dummy hash.

This ensures the endpoint takes roughly the same amount of time to respond whether the username is valid or not, preventing **timing attacks** that could be used to enumerate existing usernames.

It would be very little effort from the person submitting the PR (an LLM prompt) that generates a large amount of effort on our side (carefully reviewing code).

Please don't do that.

We'll need to block accounts that spam us with repeated automated PRs or comments.
