👋 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!

RCA/feasibility: closing unmerged. There are two independent problems with this slice. First, active security replacement #842 owns sandboxed_web_e2e.py and its tests to establish fail-closed credential-shaped stdout/stderr/timeout/service-tail redaction; this performance refactor is branched from the pre-redaction base and would create unnecessary writer/reconciliation conflict on that security boundary. Second, the patch deletes most existing .jules/bolt.md history while adding one performance note, which is unrelated destructive scope. The exponential readiness backoff may be worth reconsidering after #842 integrates, but only as a clean bounded PR with preserved history and a committed deterministic latency/behavior contract. It is not safe or dependency-correct in this branch.

Understood. Acknowledging that this work is being closed due to conflicts with the security replacement #842 and the unintended history overwrite in .jules/bolt.md. Stopping work on this task.
