πŸ‘‹ Jules, reporting for duty! I'm here to lend a hand with this pull request.

When you start a review, I'll add a πŸ‘€ emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down.

I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job!

For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with @jules. You can find this option in the Pull Request section of your global Jules UI settings. You can always switch back!

New to Jules? Learn more at jules.google/docs.


For security, I will only act on instructions from the user who triggered this task.

Closing as superseded by #193. Both PRs apply the same exact-choice validation to all three interactive prompts, while #193 is the focused canonical branch and includes realistic oversized-input and bounded-retry tests for each affected path.

This branch couples the fix to broad generated-document reformatting, a repository-wide markdownlint suppression, and build-ignore changes without adding domain-validity tests. Those unrelated changes obscure the small production correction and are not carried forward. No checks, reviews, or approvals from this PR transfer to #193.

Understood. Acknowledging that this work is now obsolete as it has been superseded by #193, and stopping work on this task.
