Contributor guide
First steps
- Read the whole issue, then the project's contributing guide.
- Comment on the issue to say you are picking it up — it saves two people doing the same work.
- Fork the repository and make your change on a branch.
- Open a pull request that references the issue number.
Research direction
No file, endpoint, or test is named. Start by locating the request that returns different status codes for existing and non-existing user IDs, then verify both cases; done means the response no longer reveals whether an ID exists.
