🛡️ Sentinel: [MEDIUM] 입력 검증에서 발생할 수 있는 정수 오버플로우 문제 수정

[seonghobae]

🚨 Severity: MEDIUM
💡 Vulnerability: 대화형 프롬프트(readline())에서 숫자를 입력받을 때 ^[0-9]+$ 정규식을 사용하여 무제한 자릿수의 입력을 허용하고 있었습니다. 이로 인해 정수 범위를 초과하는 매우 큰 값이 입력되면 as.integer() 변환 시 NA를 반환하게 되고, 후속 로직에서 예기치 않은 프로세스 크래시나 버그를 유발할 수 있습니다.
🎯 Impact: 이 패키지를 사용하는 환경에서 비정상적인 입력으로 인한 프로세스 중단 등의 문제가 발생할 수 있습니다.
🔧 Fix: 예상되는 입력값인 1과 2만 정확하게 매칭하도록 정규식을 ^[12]$로 수정하여 입력값을 안전하게 제한했습니다.
✅ Verification: 로컬에서 AFIPC_ENABLE_PACKRAT=true Rscript -e "testthat::test_dir('tests/testthat')" 및 rcmdcheck 명령어를 통해 모든 테스트가 통과하는지 확인 완료했습니다.

👋 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!

Warning

Review limit reached

@seonghobae, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 9 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

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.

Please refer docs for additional details.

Pull request overview

OpenCode cannot approve yet because required coverage evidence did not pass.

Review outcome

1. HIGH .github/workflows/opencode-review.yml:1 - Coverage evidence did not prove required test/docstring evidence

• Problem: The required coverage-evidence job result was failure, so OpenCode cannot establish approval sufficiency for this head.

• Root cause: Automated approval is only valid when the same-head coverage-evidence job proves supported repository test suites passed and configured docstring gates passed or were advisory, or reports not applicable because no supported source files or package manifests exist. Missing, failed, skipped, unavailable, or unsupported-tooling test evidence is a blocker.

• Fix: Install or configure the repository test/docstring evidence tooling when source files or package manifests exist, rerun the current-head coverage-evidence job, and approve only after it reports success with required evidence or explicit no-source not-applicable evidence.

• Regression test: Keep the approval branch checking needs.coverage-evidence.result == success before posting APPROVE, and publish REQUEST_CHANGES when coverage-evidence blocker states such as cancelled, skipped, failed, unsupported-tooling, or below-100 evidence are present.

• Result: REQUEST_CHANGES

• Reason: coverage-evidence result was failure, so required test/docstring evidence was not proven for current head 0f1f1517f375b6178539370a2e9cc549c5550b74.

Closing as superseded by #193. The production delta is identical: restrict the three documented yes/no prompts to exact 1 or 2 input. #193 consolidates that repair with bounded-risk classification, oversized-input and retry-limit regression tests, explicit test dependency metadata, and the current native-cache compatibility fix required for fresh R validation. Keeping both open would duplicate review and merge work.

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