🛡️ Sentinel: [MEDIUM] Fix readline input integer overflow vulnerability

[seonghobae]

🚨 Severity: MEDIUM
💡 Vulnerability: readline()을 통해 사용자 입력을 받을 때, ^[0-9]+$의 느슨한 정규표현식 검증을 통과한 너무 큰 숫자가 as.integer()에서 평가될 때 NA를 반환하는 integer overflow coercion 취약점 존재
🎯 Impact: 사용자가 의도치 않게 거대한 값을 입력했을 때 NA가 제어 흐름에 포함되어 프로세스 충돌(crash)이나 예측할 수 없는 예외 발생 가능
🔧 Fix: 정규표현식을 ^[12]$로 구체화하여, 정확히 의도된 선택지만 허용하도록 입력 검증 강화
✅ Verification: Rscript -e "testthat::test_dir('tests/testthat')" 명령어로 관련 에러 처리 테스트가 성공하는지 검증 완료

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 d1a41662e9f88d1bbc39b3c6b69a6ff672c50ea9.
