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

When you start a review, I'll add a 👀 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!

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

At typical activity levels, the full plan allowance applies. Higher sustained activity can lower the allowance until earlier attempts leave the 7-day window.

Superseded by #473. Both lanes remove role="status" from the same build-time empty-directory row, but #473 is the canonical, older bounded repair: it carries the explicit whole-page negative regression (assertFalse rather than merely deleting the old positive assertion), canonical doctoring with WAI-ARIA 1.2 / WCAG 2.2 claim boundaries and rollback condition, and the changelog contract. Keeping this Jules-generated duplicate open would create competing writers for the same markup/tests without adding buyer-visible behavior. No check or review evidence from this PR transfers to #473.

Understood. Acknowledging that this work is now obsolete and stopping work on this task.
