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

How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

🛡️ Sentinel: implement secure dual rate-limiting
Severity: HIGH
Vulnerability: Account Lockout Denial of Service via Target-Based Bucket Pollution
Impact: A malicious actor could flood authentication endpoints with a target's email, locking legitimate enrollees out of their accounts.
Fix:
rateLimitDualinsidesrc/lib/rate-limit.tsto perform dual rate-limiting on both client IP (usingx-forwarded-for/x-real-ip) and target identifiers (such as emails).rateLimitDualintosignUpActionandsignInActionserver actions.src/lib/__tests__/rate-limit.test.tsto achieve 100% test coverage and ensure zero regressions.PR created automatically by Jules for task 1277239486621716037 started by @projectamazonph
