Internal Knowledge Assistant Challenge

Welcome. This repository is a 60-minute engineering challenge for senior product engineers working with AI-assisted development tools.

The app is a small Next.js internal knowledge assistant. A conversation answer should show the sources it cites, but the current implementation always renders No sources available.

Your Task

Fix citation rendering so answers show their linked sources.

Please submit a pull request that includes:

• The code change.
• Any tests you believe are necessary.
• A short PR note answering:
  • What did you change?
  • What did you test?
  • Did you find any misleading or outdated project guidance?

Setup

npm install
npm run dev

Open http://localhost:3000.

Tests

npm test

At the start of the challenge, one test is expected to fail. Your PR should make the candidate-facing test suite pass.

Constraints

• Keep the fixture-only architecture. Do not add a database, auth provider, API server, or external service.
• Prefer a small, well-tested fix over a broad refactor.
• The app should remain understandable to another engineer reviewing the PR.
