🛡️ Sentinel: [MEDIUM] readline 유효성 검사에서 정수 오버플로우 강제 변환 문제 수정

[seonghobae]

🚨 Severity: MEDIUM
💡 Vulnerability: readline() 입력을 검증할 때 ^[0-9]+$ 정규식을 사용하여, 사용자가 정수 표현 범위를 초과하는 매우 긴 숫자를 입력하면 as.integer()가 NA를 반환하고, 후속 로직에서 프로세스가 비정상 종료될 수 있는 취약점이 존재했습니다.
🎯 Impact: 악의적인 사용자가 과도하게 큰 정수 입력을 통해 애플리케이션 충돌(Denial of Service)을 유발할 수 있습니다.
🔧 Fix: readline() 입력이 허용되는 정확한 값(1 또는 2)만 매칭되도록 정규식을 ^[12]$로 수정하여 검증 로직을 강화했습니다.
✅ Verification: AFIPC_ENABLE_PACKRAT=true Rscript -e "testthat::test_dir('tests/testthat')" 명령어를 실행하여 단위 테스트가 정상적으로 통과하는지 확인했습니다.

autoFIPC의 세 대화형 입력 검증 정규식을 ^[12]$로 제한했습니다. 정수 범위 초과 입력 위험과 예방책을 .jules/sentinel.md에 기록했습니다.

Changes

사용자 입력 검증

Layer / File(s)	Summary
허용 입력 검증 및 보안 문서화 R/aFIPC.R, .jules/sentinel.md	checkCorrect, checkoldformBILOGprior, checknewformBILOGprior는 1 또는 2만 허용합니다. 관련 정수 변환 취약점과 예방책을 문서화했습니다.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to 12cb7

The change restricts interactive input to the supported values 1 and 2 across the affected paths, preventing oversized numeric input from reaching integer conversion. No actionable merge-blocking risk remains; targeted regression tests would provide additional confidence.
