What changed
- Live preview now runs a project's server file alongside the page, so buttons that call the app's own API work during an assessment. Full-stack starter projects were updated to run this way.
- Coding agents can now rename files. React projects preview correctly when the code imports React, and agents no longer rewrite plain HTML projects into React.
- Candidates now see a warning before submitting with unanswered questions. Text pasted into the AI chat box no longer counts as pasted code in the integrity review.
