π Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a π 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. For security, I will only act on instructions from the user who triggered this task. |

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.

Pull request overview
This PR hardens autoFIPC()βs interactive CLI prompts against integer overflow coercion by strictly limiting accepted responses to the expected categorical options (1 or 2), preventing as.integer() from producing NA on extremely long numeric inputs.
Changes:
- Tightened three
readline()input validations inR/aFIPC.Rfrom^[0-9]+$to^[12]$to only accept1or2. - Added a Sentinel log entry documenting the interactive input overflow-coercion issue and its prevention guidance.

| File | Description |
|---|---|
| R/aFIPC.R | Restricts interactive prompt inputs to 1/2 to prevent overflow coercion issues during as.integer() conversion. |
| .jules/sentinel.md | Documents the vulnerability and mitigation guidance for future prevention. |

| **Learning:** In R, optional boolean parameters that default to `NULL` should be validated using explicit runtime type validation (e.g., `if (!is.null(flag) && (!is.logical(flag) || length(flag) != 1 || is.na(flag)))`). | ||
| **Prevention:** Always implement explicit runtime type validation for optional boolean parameters. | ||
