🛡️ Sentinel: [MEDIUM] Fix integer coercion vulnerability in interactive prompts

[seonghobae]

🚨 심각도: MEDIUM
💡 취약점: aFIPC.R 내 대화형 사용자 입력(readline())의 숫자 유효성 검사가 ^[0-9]+$ 형식으로 되어 있어 너무 큰 숫자가 입력될 경우 발생할 수 있는 취약점입니다.
🎯 영향: 지나치게 큰 숫자(예: 99999999999999999999)를 입력하면 문자열 정규식 통과 후 as.integer()에서 NA로 변환되어, 이후 if문 등에서 missing value where TRUE/FALSE needed 에러로 프로그램 프로세스 크래시(DoS)가 발생합니다.
🔧 해결 방안: 정규 표현식을 ^[12]$로 수정하여 허용되는 선택지("1" 또는 "2")만 정확히 매치하도록 개선했습니다.
✅ 검증 방법: R 스크립트의 테스트 스위트가 정상 작동하는 것을 확인했으며, 범위를 벗어난 값을 주입하여 크래시되지 않는 것을 확인했습니다.

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 64ef05127bcbc669a42d1e26309bac86a36479c4.
