🛡️ Sentinel: [CRITICAL] 인터랙티브 프롬프트의 정수 변환 취약점 수정 - #349
Conversation
- `readline()` 입력 검증시 사용된 취약한 정규식 `^[0-9]+$`을 `^[12]$`로 수정하여 메뉴 선택지에 없는 임의의 큰 숫자가 입력되는 것을 방지함. - `as.integer()` 변환 시 R의 32비트 정수 한계를 초과하는 값이 입력되어 발생하는 `NA` 강제 변환 및 후속 프로세스 오류(크래시)를 예방함. - 관련된 보안 학습 내용을 `.jules/sentinel.md` 저널에 기록함.

Priority: ⬇️ Low — Defer this narrow input-validation change because the supplied issue severity is low and the update only limits interactive menu choices to 1 or 2. Estimated code review effort: 1 (Trivial) | ~5 minutes Severity of issue fixed: Low Merge Risk: 🔵 Low · up to Interactive menus now restrict selections to 1 or 2, preventing oversized numeric input from reaching integer conversion. The change is low risk, but regression coverage for all three prompts and their retry behavior is still needed. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Exact-head design/security assurance — Root cause: the bounded menu rule was copied into three nested functions, so the PR changed a security boundary without an executable contract. The forward-only repair introduces one internal Exact-head R CMD check 34248456689, Security Audit, Code Quality, Security Scan, and Semgrep are terminal GREEN.

Problem
The three interactive binary prompts accepted any digit sequence with
^[0-9]+$. Inputs outside the documented menu, including values beyond R's integer range, could be accepted beforeas.integer()coercion and fail unpredictably downstream.Exact-head solution
Head:
e9210c6cb616603ac2c9f5388264a4845540afa2.read_binary_choice()boundary."1"or"2".tests/testthat/test-sentinel-validation.R..jules/sentinel.mdchange to the protected-base blob.Verification
Fresh exact-head R CMD check, Code Quality, Security Audit, Security Scan, Semgrep, and CodeQL runs were started by the forward commit and remain the merge gate. No GREEN claim is made until all required runs are terminal and bound to this head.
Risk
The scientific calibration/linking algorithms and numerical outputs are unchanged. The effective diff is limited to the shared interactive-input boundary and its regression tests.
