🚨 Severity: MEDIUM 💡 Vulnerability: `readline()` 입력 검증 시 제한 없는 정규식(`^[0-9]+$`)을 사용하여 정수 오버플로우로 인한 크래시 가능성이 있었습니다. 🎯 Impact: 악의적 또는 실수로 큰 숫자를 입력할 경우 프로세스가 크래시될 수 있습니다. 🔧 Fix: 정규식을 `^[12]$`로 수정하여 허용되는 값만 입력받도록 개선했습니다. ✅ Verification: 테스트 스위트가 통과하고 유효하지 않은 입력에 대해 올바르게 실패하는지 확인했습니다.

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

Three interactive prompts document exactly two valid choices,
1and2, but the protected behavior accepted any decimal string matching^[0-9]+$beforeas.integer()and downstream branching. Values such as3therefore passed the input validator despite not being a documented menu choice. Very large decimal strings can also coerce toNA.The earlier generated framing called this a MEDIUM integer-overflow/process-crash vulnerability. The repository evidence does not establish memory corruption, integer wrap, or a process-crash exploit. The supported finding is an interactive input-contract/reliability defect: values outside the documented choice domain must be rejected before coercion and control flow.
R Core documents that integer coercion can produce
NAfor values outside the representable range; this is coercion/validation evidence, not proof of an overflow exploit: https://stat.ethz.ch/CRAN/doc/manuals/r-patched/fullrefman.pdf.Causal repair and regression
Each prompt now validates with
^[12]$beforeas.integer(), preserving the existing three-attempt fail-closed behavior.The regression is now named for the actual contract and is deterministic:
0,3, and12;1needed to reach that prompt, then rejects out-of-domain/non-numeric/oversized values;sample()data.The branch also repairs intervening unrelated drift without rewriting history:
.Rbuildignore,.jules/sentinel.md, andtest_dummy.Rare restored to protected authority and the unrelated.markdownlint.jsonaddition is removed.mockeryremains inSuggestsbecause the focused regression uses it.Exact-head evidence
Fresh workflows for

Keep Draft until one unchanged exact head has terminal applicable checks, zero valid unresolved review findings, fresh protected-base compatibility, and the then-live independent-review requirement.
Do not restore repository-wide Sentinel doctrine, reclassify this as integer overflow without evidence, manufacture severity, weaken the three-attempt contract, reintroduce random fixtures, suppress scanners, self-approve, force-push, destructively rebase, or create source-neutral churn merely to trigger workflows.
